    Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder and the most disabling condition of heterotopic (extraskeletal) ossification in humans. Extraskeletal bone formation associated with inflammation preceding the osseous conversion usually begins in the first decade, predominantly in the head, neck, and shoulders. All patients have malformed great toes. Most patients have a spontaneous mutation of the ACVR1 gene. We report a 17-year-old girl with malformed great toes who had her first episode of heterotopic ossification and impaired mobility of the left hip at the age of 13 years. No inflammatory fibroproliferative masses preceded the onset of heterotopic ossification. Radiographic studies demonstrated myositis ossificans, but failure to associate the great toe malformation with heterotopic ossification led to a failure to diagnose FOP. She underwent repeated and unnecessary operative procedures to remove a recurrent lesion. FOP was finally suspected when the great toe malformation was correlated with the trauma-induced heterotopic ossification. Genetic analysis confirmed the presence of the classic FOP mutation (ACVR1 c.617G>A; R206H). This case highlights the importance of examining the great toes in anyone with heterotopic ossification. The association of malformations of the great toe with heterotopic ossification in all cases of classic FOP will lead to prompt clinical diagnosis and the prevention of iatrogenic harm.

    Episodic flare-ups of fibrodysplasia ossificans progressiva (FOP) are characterized clinically by severe, often posttraumatic, connective tissue swelling and intramuscular edema, followed histologically by an intense and highly angiogenic fibroproliferative reaction. This early inflammatory and angiogenic fibroproliferative response is accompanied by the presence of abundant mast cells far in excess of other reported myopathies. Using an injury-induced, constitutively-active transgenic mouse model of FOP we show that mast cell inhibition by cromolyn, but not aprepitant, results in a dramatic reduction of heterotopic ossification. Cromolyn, but not aprepitant, significantly decreases the total number of mast cells in FOP lesions. Furthermore, cromolyn specifically diminishes the number of degranulating and resting degranulated mast cells in pre-osseous lesions. This work demonstrates that consideration of FOP as a type of localized mastocytosis may offer new therapeutic interventions for treatment of this devastating condition.

    Fibrodysplasia ossificans progressiva (FOP) leads to disabling heterotopic ossification (HO) from episodic flare-ups. However, the natural history of FOP flare-ups is poorly understood. A 78-question survey on FOP flare-ups, translated into 15 languages, was sent to 685 classically-affected patients in 45 countries (six continents). Five hundred patients or knowledgeable informants responded (73%; 44% males, 56% females; ages: 1 to 71 years; median: 23 years). The most common presenting symptoms of flare-ups were swelling (93%), pain (86%), or decreased mobility (79%). Seventy-one percent experienced a flare-up within the preceding 12 months (52% spontaneous; 48% trauma-related). Twenty-five percent of those who had received an intramuscular injection reported an immediate flare-up at the injection site, 84% of whom developed HO. Axial flare-ups most frequently involved the back (41.6%), neck (26.4%), or jaw (19.4%). Flare-ups occurred more frequently in the upper limbs before 8 years of age, but more frequently in the lower limbs thereafter. Appendicular flare-ups occurred more frequently at proximal than at distal sites without preferential sidedness. Seventy percent of patients reported functional loss from a flare-up. Thirty-two percent reported complete resolution of at least one flare-up and 12% without any functional loss (mostly in the head or back). The most disabling flare-ups occurred at the shoulders or hips. Surprisingly, 47% reported progression of FOP without obvious flare-ups. Worldwide, 198 treatments were reported; anti-inflammatory agents were most common. Seventy-five percent used short-term glucocorticoids as a treatment for flare-ups at appendicular sites. Fifty-five percent reported that glucocorticoids improved symptoms occasionally whereas 31% reported that they always did. Only 12% reported complete resolution of a flare-up with glucocorticoids. Forty-three percent reported rebound symptoms within 1 to 7 days after completing a course of

    Fibrodysplasia ossificans progressiva (FOP) is an extremely rare and disabling genetic disorder of connective tissue. The condition is characterized by congenital malformation of the great toes and by progressive heterotopic ossification of the tendons, ligaments, fasciae, and striated muscles. Fibrodysplasia ossificans progressiva occurs sporadically and is transmitted as a dominant trait with variable expression and complete penetrance. Reproductive fitness is low. There are fewer than 150 known patients with the disorder in the United States. A point prevalence of one affected patient in every 2 million of population has been observed. There is no sexual, racial, or ethnic predilection. The disease presents in early life; its course is unavoidably progressive. Most patients are confined to a wheelchair by the third decade of life and often succumb to pulmonary complications in the 5th/6th decade of life. At present there is no effective prevention or treatment. The recent discovery of overproduction of bone morphogenetic protein-4 in lesional cells and lymphocytic cells of affected patients provides a clue to both the underlying pathophysiology and potential therapy. The FOP gene has recently been mapped to human chromosome 4 q 27-31. (orig.)

    2011-12-01

    Full Text Available Abstract Fibrodysplasia ossificans progressiva (FOP is a severely disabling heritable disorder of connective tissue characterized by congenital malformations of the great toes and progressive heterotopic ossification that forms qualitatively normal bone in characteristic extraskeletal sites. The worldwide prevalence is approximately 1/2,000,000. There is no ethnic, racial, gender, or geographic predilection to FOP. Children who have FOP appear normal at birth except for congenital malformations of the great toes. During the first decade of life, sporadic episodes of painful soft tissue swellings (flare-ups occur which are often precipitated by soft tissue injury, intramuscular injections, viral infection, muscular stretching, falls or fatigue. These flare-ups transform skeletal muscles, tendons, ligaments, fascia, and aponeuroses into heterotopic bone, rendering movement impossible. Patients with atypical forms of FOP have been described. They either present with the classic features of FOP plus one or more atypical features [FOP plus], or present with major variations in one or both of the two classic defining features of FOP [FOP variants]. Classic FOP is caused by a recurrent activating mutation (617G>A; R206H in the gene ACVR1/ALK2 encoding Activin A receptor type I/Activin-like kinase 2, a bone morphogenetic protein (BMP type I receptor. Atypical FOP patients also have heterozygous ACVR1 missense mutations in conserved amino acids. The diagnosis of FOP is made by clinical evaluation. Confirmatory genetic testing is available. Differential diagnosis includes progressive osseous heteroplasia, osteosarcoma, lymphedema, soft tissue sarcoma, desmoid tumors, aggressive juvenile fibromatosis, and non-hereditary (acquired heterotopic ossification. Although most cases of FOP are sporadic (noninherited mutations, a small number of inherited FOP cases show germline transmission in an autosomal dominant pattern. At present, there is no definitive

    Full Text Available Fibrodysplasia ossificans progressiva is a rare genetic disease characterized by widespread soft tissue ossification and congenital stigmata of the extremities. We report on a male child followed for ten years since the age of 3 years and 9 months, when the diagnosis was made. He was born with bilateral hypoplasic hallux valgus and ventricular septal defect, corrected by transsternal approach when 32 months old. Restriction of neck mobility followed and foci of ectopic ossification appeared. Four crises of disease exacerbation were treated with oral prednisone and/or other antiinflammatory drugs. Sodium etidronate 5 to 10 mg/kg/day was prescribed intermittently during about six years but was discontinued due to osteopenia. The disease course has been relentless, with severe movement restriction including the chest wall. A review showed few similar case reports in the Brazilian literature. We revisit the criteria for diagnosis and the essentials of management and treatment.

    1999-10-01

    Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder characterized by progressive soft tissue ossification. Although signs may be present at birth, the first appearance of ectopic bone typically occurs in early childhood. The primary target is the axial musculature. Eventually ectopic bone also occurs in ligaments, fascia, aponeurosis, tendons, and joint capsules of the appendicular skeleton with a proximal to distal predilection. As the disease advances, mobility becomes restricted, and affected individuals are typically limited to bed or chair by their early 30s. This report describes a 30-year-old woman with advanced FOP. She had a fused spine and a fixed pelvis, with hips and knees locked in flexion and feet in plantarflexion. Her upper limb mobility was similarly restricted. She was not able to stand upright or sit independently. The modification of a commercially available power wheelchair that allowed the patient to maintain her employment as a preschool teacher and custom shoes are described. Creative physiatric intervention is essential to liberate human potential for people with FOP.

    Full Text Available Fibrodysplasia ossificans progressiva (FOP is a rare autosomal dominant disorder characterized by postnatal progressive heterotopic ossification of the connective tissue and congenital malformation of the big toes. We report on a nine-year-old girl with clinical and radiological features of FOP. She was born with bilateral hallux valgus and at the age of nine presented an indurate mass in the left cervical region that was painful. A significant decreased range of motion in all levels of the spine and shoulder girdle was found. The radiographs showed heterotopic ossification in the thoracic region. The patient had two outbreaks of the disease ("flare-ups" that were treated with prednisone 2 mg/kg/day for four days. After the "flare-ups", she had a continuous therapy with a Cox-2 inhibitor (25 mg/day and a leukotriene inhibitor, montelukast (10 mg/day.A fibrodisplasia ossificante progressiva (FOP é doença rara, autossômica dominante, caracterizada por ossificação heterotópica progressiva pós-natal do tecido conjuntivo e malformação congênita dos háluces.

    Fibrodysplasia ossificans progressiva (FOP) is a rare connective tissue disorder characterized by congenital malformation of the great toes and by progressive heterotopic ossification of the tendons, ligaments, fasciae and skeletal muscles. We document the radiologic manifestation of FOP passed from a sporadically affected father to each of his two children (a son and a daughter). Previous consideration of a genetic etiology was based on the fact that the disease has been reported in several sets of monozygotic twins and that increased paternal age has been associated with sporadic occurrence of the disorder. Although autosomal-dominant transmission has long been suspected, the findings in this family provide confirmation for such inheritance and a basis for the diagnosis and counseling of patients with FOP.

  14. Application of human induced pluripotent stem cells to model fibrodysplasia ossificans progressiva.

    2018-04-01

    Fibrodysplasia ossificans progressiva (FOP) is a genetic condition characterized by massive heterotopic ossification. FOP patients have mutations in the Activin A type I receptor (ACVR1), a bone morphogenetic protein (BMP) receptor. FOP is a progressive and debilitating disease characterized by bone formation flares that often occur after trauma. Since it is often difficult or impossible to obtain large amounts of tissue from human donors due to the risks of inciting more heterotopic bone formation, human induced pluripotent stem cells (hiPSCs) provide an attractive source for establishing in vitro disease models and for applications in drug screening. hiPSCs have the ability to self-renew, allowing researchers to obtain large amounts of starting material. hiPSCs also have the potential to differentiate into any cell type in the body. In this review, we discuss how the application of hiPSC technology to studying FOP has changed our perspectives on FOP disease pathogenesis. We also consider ongoing challenges and emerging opportunities for the use of human iPSCs in drug discovery and regenerative medicine. Copyright © 2017 Elsevier Inc. All rights reserved.

    We have clinically encountered children with fibrodysplasia ossificans progressiva who had abnormal calcaneal ossification. To evaluate whether calcaneal ossification variants are significant radiographic findings in children with fibrodysplasia ossificans progressiva. Lateral feet radiographs in nine children who fulfilled the diagnostic criteria of fibrodysplasia ossificans progressiva were reviewed. The studies were obtained during infancy or early childhood. Fourteen lateral foot radiographs of fibrodysplasia ossificans progressiva were available for this study (ages at examination: 1-104 months). Four children ages 2 months to 11 months showed double calcaneal ossification centers; 7 children had plantar calcaneal spurs that decreased in size with age. Overall, eight of nine children with fibrodysplasia ossificans progressiva demonstrated double calcaneal ossifications and/or plantar calcaneal spurs in infancy or childhood. Double calcaneal ossification centers in early infancy and plantar calcaneal spurs in childhood are frequently seen in children with fibrodysplasia ossificans progressiva and may be a useful radiologic indicator for early diagnosis.

    T o present the clinical findings of a patient with fibrodysplasia ossificans progressiva (FOP), highlighting peculiarities of dental treatment in patients with this condition. FOP is a rare genetic disease characterized by skeletal malformations and ectopic ossifications in skeletal muscles, tendons, ligaments and aponeurosis. Exacerbation of these ossifications can be caused by dental treatment, resulting in disease progression. A 26-year-old male patient with a diagnosis of FOP was referred to our service for dental treatment. The patient presented decreased mobility in peripheral joints (knees and elbows), postural disability (ankylosis of the vertebral column), lateral deviation and shortness of the hallux, as well as heterotopic ossifications on the hands and back. The implementation of conservative dental procedures, such as oral hygiene instructions and recurrent topical fluoride applications, were performed in addition to endodontic and restorative treatments. Brief dental appointments were conducted without using regional anesthesia or dental dam clamps. The dental chair was positioned at 45° to provide more comfort and to avoid exacerbating the disease. The patient has now completed 6 months of follow-up and is free of heterotopic ossifications resulting from dental treatment. The dental treatment modifications implemented for the present case were sufficient to establish good oral health and to prevent the formation of heterotopic ossifications in the maxillofacial region. FOP is a rare disease dentists must familiarize themselves with to provide adequate, personalized treatment, which minimizes traumas that may exacerbate the disease.

  1. ACVR1, a Therapeutic Target of Fibrodysplasia Ossificans Progressiva, Is Negatively Regulated by miR-148a

    Jun Cheng

    2012-02-01

    Full Text Available Fibrodysplasia ossificans progressiva (FOP is a rare congenital disorder of skeletal malformations and progressive extraskeletal ossification. There is still no effective treatment for FOP. All FOP individuals harbor conserved point mutations in ACVR1 gene that are thought to cause ACVR1 constitutive activation and activate BMP signal pathway. The constitutively active ACVR1 is also found to be able to cause endothelial-to-mesenchymal transition (EndMT in endothelial cells, which may cause the formation of FOP lesions. MicroRNAs (miRNAs play an essential role in regulating cell differentiation. Here, we verified that miR-148a directly targeted the 3' UTR of ACVR1 mRNA by reporter gene assays and mutational analysis at the miRNA binding sites, and inhibited ACVR1 both at the protein level and mRNA level. Further, we verified that miR-148a could inhibit the mRNA expression of the Inhibitor of DNA binding (Id gene family thereby suppressing the BMP signaling pathway. This study suggests miR-148a is an important mediator of ACVR1, thus offering a new potential target for the development of therapeutic agents against FOP.

    Full Text Available Fibrodysplasia ossificans progressiva (FOP is an exceptionally rare genetic disease that is characterised by congenital malformations of the great toes and progressive heterotopic ossification (HO in specific anatomical areas. This disease is caused by a mutation in activin receptor IA/activin-like kinase-2 (ACVR1/ALK2. A Mexican family with one member affected by FOP was studied. The patient is a 19-year-old female who first presented with symptoms of FOP at 8 years old; she developed spontaneous and painful swelling of the right scapular area accompanied by functional limitation of movement. Mutation analysis was performed in which genomic DNA as PCR amplified using primers flanking exons 4 and 6, and PCR products were digested with Cac8I and HphI restriction enzymes. The most informative results were obtained with the exon 4 flanking primers and the Cac8I restriction enzyme, which generated a 253 bp product that carries the ACVR1 617G>A mutation, which causes an amino acid substitution of histidine for arginine at position 206 of the glycine-serine (GS domain, and its mutation results in the dysregulation of bone morphogenetic protein (BMP signalling that causes FOP.

    Fibrodysplasia ossificans progressiva, also known as myositis ossificans progressiva, is characterized by congenital skeletal malformations and progressive ectopic bone formation in connective tissues. The disorder presents as rapidly growing masses usually in the neck or paraspinal region with stiffness in the adjoining joints. The preosseous lesions involve the fascia, ligaments, tendons, and skeletal muscle. These lesions occasionally resolve but more often progress to form ectopic ossification. We present a boy who had a characteristic clinical presentation. Magnetic resonance (MR) imaging conducted in the preosseous stage of the lesion revealed the pathology, resulting in early therapy and resolution of the preosseous lesion without progression to ossification. To the best of our knowledge, post-therapy follow-up MR imaging in such a case has not been reported. (orig.)

    Full Text Available Myositis ossificans progressiva/fibrodysplasia ossificans progressiva (MOP, is an autosomal dominant mesodermal tissue disorder, characterized by an initial period of inflammation and subsequent proliferation of fibrous tissue with the formation of ectopic bone tissue. The incidence of MOP is one case per two million people. The ectopic bone tissue formed is located in soft tissue mainly in the connective tissue of striated musculature. We report MOP in an 18-year old female who presented with multiple tender, hard swelling in various parts of the body associated with stiffness and limitations of movements. A literature review of the subject showed few similar case reports in the literature. We revisit the criteria for diagnosis and the essentials of management and treatment of MOP as it is rare being a rare condition, and treatment guidelines are not clear.

Most of the isolated classic cases of FOP showed heterozygous mutation in the ACVR1 gene on chromosome 2q23 that encodes a bone morphogenetic protein BMP (ALK2. The most common mutation is (c.617G > A leading to the amino acid substitution of arginine by histidine (p.Arg206His. We currently report on an Egyptian infant with a sporadic classic FOP in whom c.617G > A mutation had been documented. The patient presented with the unique congenital malformation of big toe and radiological evidence of heterotopic ossification in the back muscles. The triggering trauma was related to the infant's head, however; neither neck region nor sites of routine intramuscular vaccination given during the first year showed any ossifications. Characterization of the big toe malformation is detailed to serve as an early diagnostic marker for this rare disabling disease.

    Fibrodysplasia ossificans progressiva is one of the most devastating constitutional diseases of the bone, and may be a valid example to establish the role of Primary Care in the care of rare diseases. Although rare diseases usually present with marked anomalies, they can mimic signs and symptoms of common disorders, with the risk of going unnoticed. For this reason, all health professionals should proceed with a reasonable suspicion when confronted with a patient with an apparently common disease with atypical symptoms and a non-conventional progress. The care given by the Primary Care team along with other health care services are fundamental in the integrated and individualised follow-up. The quality of care in rare diseases must not be inferior to that provided to the other chronic diseases, since, besides being a requirement of justice and fairness, these patients are, in essence, the "paradigm of chronicity".

    1997-01-01

    Fibro-dysplasia ossificans progressiva is a rare congenital disease that affects children under the age of five years. Soft tissue swelling of the cervical and dorsal regions with local pain, warmth and low grade fever are the early clinical manifestations, usually associated with hallux valgus and microdactyly of the fingers and toes. Calcifications of the fascias and muscles cause muscular contractures leading to progressive disability and restrictive lung disease. In the early stage, CT shows edema of the soft tissues and later on, calcifications of muscular fascia. The association of these radiographic and CT findings is specific and should avoid muscular biopsies which are known to be an aggravating factor in this disease. (author)

  9. Restricted Mandibular Movement Attributed to Ossification of Mandibular Depressors and Medial Pterygoid Muscles in Patients With Fibrodysplasia Ossificans Progressiva: A Report of 3 Cases.

    Okuno, Tetsuko; Suzuki, Hitoshi; Inoue, Akio; Kusukawa, Jingo

    2017-09-01

    Fibrodysplasia ossificans progressiva (FOP) is an extremely rare genetic condition characterized by congenital malformation and progressive heterotopic ossification (HO) caused by a recurrent single nucleotide substitution at position 617 in the ACVR1 gene. As the condition progresses, HO leads to joint ankylosis, breathing difficulties, and mouth-opening restriction, and it can shorten the patient's lifespan. This report describes 3 cases of FOP confirmed by genetic testing in patients with restricted mouth opening. Each patient presented a different onset and degree of jaw movement restriction. The anatomic ossification site of the mandibular joint was examined in each patient using reconstructed computed tomographic (CT) images and 3-dimensional reconstructed CT (3D-CT) images. A 29-year-old woman complained of jaw movement restriction since 13 years of age. 3D-CT image of the mandibular joint showed an osseous bridge, formed by the mandibular depressors that open the mouth, between the hyoid bone and the mentum of the mandible. A 39-year-old man presented with jaw movement restriction that developed at 3 years of age after a mouth injury. 3D-CT image of the jaw showed ankylosis of the jaw from ossification of the mandibular depressors that was worse than in patient 1. CT images showed no HO findings of the masticatory muscles. To the authors' knowledge, these are the first 2 case descriptions of the anatomic site of ankylosis involving HO of the mandibular depressors in the jaw resulting from FOP. In contrast, a 62-year-old bedridden woman with an interincisal distance longer than 10 mm (onset, 39 years of age) had no HO of the mandibular depressors and slight HO of the medial pterygoid muscle on the right and left sides. These findings suggest that restricted mouth opening varies according to the presence or absence of HO of the mandibular depressors. Copyright © 2017. Published by Elsevier Inc.

  13. Myositis Ossificans.

    Walczak, Brian E; Johnson, Christopher N; Howe, B Matthew

    2015-10-01

    Myositis ossificans is a self-limiting, benign ossifying lesion that can affect any type of soft tissue, including subcutaneous fat, tendons, and nerves. It is most commonly found in muscle as a solitary lesion. Ossifying soft-tissue lesions historically have been inconsistently classified. Fundamentally, myositis ossificans can be categorized into nonhereditary and hereditary types, with the latter being a distinct entity with a separate pathophysiology and treatment approach. The etiology of myositis ossificans is variable; however, clinical presentation generally is characterized by an ossifying soft-tissue mass. Advanced cross-sectional imaging alone can be nonspecific and may appear to be similar to more sinister etiologies. Therefore, the evaluation of a suspicious soft-tissue mass often necessitates multiple imaging modalities for accurate diagnosis. When imaging is indeterminate, biopsy may be required for a histologic diagnosis. However, histopathology varies based on stage of evolution. The treatment of myositis ossificans is complex and is often made in a multidisciplinary fashion because accurate diagnosis is fundamental to a successful outcome.

    Mandibular periostitis ossificans was assessed in a 18-year-old black boy. This form of chronic osteomyelitis (Garré osteomyelitis) resulted from a periostitis on the 4.8 in association with an infected and ankylosed 4.7. Clinically a firm swelling of the right mandibular angle was noticeable. The diagnosis was confirmed by computed tomography and biopsy. After extraction of the causative teeth, in combination with an antibiotic treatment, a good evolution was obtained. The possible pathogenesis and the differential diagnosis are discussed.

    The 35 patients who have suffered from myositis ossificans were investigate for 11 years. They were post traumatic patients. They trauma was divided into 3 groups; spinal cord injury, direct injury (fracture) and mixed type involving both. We evaluated the age distribution, the frequency of myositis ossificans, predilection site, bilaterally and relation between predilection site and bilaterally to the type of trauma. The results are as follows; 1. The age distribution was highest in 4th decades (12 among 35 patients). 2. In regard to distribution of 35 patients, spinal cord injury were most common (15 cases, 43%), the fracture nextly common (14, 40%) and then mixed type (6, 17%). 3. Among 51 cases of myositis ossificans, the frequency was highest in spinal cord injury (25 cases, 49%), next was fracture (14, 27%). 4. The predilection site of myositis ossificans were thigh (18 cases, 35%), hip (17, 33%) and buttock (6, 12%). 5. In correlation between predilection site of myositis ossificans and level of spinal cord injury, hip is the most frequent site in thoracic injury. 6. The bilaterally of myositis ossificans is 39% (20 among 51 lesions).

    A review of the radiographs of 60 hemophilia patients showed nine (15%) with ectopic new bone formation. Three of these patients had multiple sites of involvement. The high frequency discovered in this series contrasts with the paucity of descriptions to be found in the literature. This process of myositis ossificans affects the lower half of the body and probably represents dysplastic metaplasia developing at the site of an intramuscular hematoma when remote from bone, as well as ossification of hemorrhagic lesions related to the periosteum. In conventional radiographs anatomic localization of bone foci is difficult, but use of computed tomography permits precise identification of the affected muscle. There is negligible disability associated with this condition.

    2014-01-01

    The term myositis ossificans refers to the formation of ossifications in the muscles, ligaments and fascias, usually as a result of trauma. Fibrodysplasia ossificans progressiva is a rare genetic disease in which heterotopic ossifications appear in early childhood and are accompanied by feet and spine defects. We present a case of a 31-year-old woman with massive heterotopic ossifications who suffered multiple injuries. We would like to emphasize the role of computed tomography in the exact localization of ossifications. Thanks to the volume rendering techniques and 3D image reconstructions, it is possible to precisely determine the position of ossifications in relation to the internal organs and blood vessels, allowing to schedule the surgery to remove the lesions

  1. FOP is a centriolar satellite protein involved in ciliogenesis.

    Joanna Y Lee

    Full Text Available Centriolar satellites are proteinaceous granules that are often clustered around the centrosome. Although centriolar satellites have been implicated in protein trafficking in relation to the centrosome and cilium, the details of their function and composition remain unknown. FOP (FGFR1 Oncogene Partner is a known centrosome protein with homology to the centriolar satellite proteins FOR20 and OFD1. We find that FOP partially co-localizes with the satellite component PCM1 in a cell cycle-dependent manner, similarly to the satellite and cilium component BBS4. As for BBS4, FOP localization to satellites is cell cycle dependent, with few satellites labeled in G1, when FOP protein levels are lowest, and most labeled in G2. FOP-FGFR1, an oncogenic fusion that causes a form of leukemia called myeloproliferative neoplasm, also localizes to centriolar satellites where it increases tyrosine phosphorylation. Depletion of FOP strongly inhibits primary cilium formation in human RPE-1 cells. These results suggest that FOP is a centriolar satellite cargo protein and, as for several other satellite-associated proteins, is involved in ciliogenesis. Localization of the FOP-FGFR1 fusion kinase to centriolar satellites may be relevant to myeloproliferative neoplasm disease progression.

  2. Merits of magnetic resonance imaging (MRI) for the diagnosis of myositis ossificans circumscripta

    Bouchardy, L.; Garcia, J.

    1994-01-01

    A retrospective study of 5 cases, 4 of myositis ossificans circumscripta (MOC) and 1 of non-ossificans myositis, is presented. The clinical presentation was a painful soft-tissues swelling, and the final diagnosis was established by biopsy in 3 cases and clinical evolution in 2 cases. Different types of imaging techniques were performed: 4 MRI, 2 arteriographies, 3 Tc 99m scintigraphies, 3 US, 3 CT and plain film radiographs for all patients. MOC is a benign process (as opposed to myositis ossificans progressiva, which is an hereditary pathology with a fatal prognosis) with 3 phases of evolution: an acute or pseudo-inflammatory phase, a sub-acute or pseudo-tumoral phase and a chronic phase with a spontaneous healing. The radiologic diagnostic findings are dependent of the phase of the disease. The calcifications are seen earlier with scintigraphy than plain films, with US being less helpful. A heterogenous mass and calcifications are seen with CT. MRI allows the characterization of oedema during the acute phase and sometimes can exclude a malignant process. MRI is the best method for an early diagnosis, the differential diagnosis and to follow the evolution. (authors). 26 refs., 8 figs

    1999-01-01

    Myositis ossificans is characterized by a benign, self-limiting, ossifying mass of the white tissue. In the present report, we describe the magnetic resonance (MR) images in three cases of myositis ossificans in pediatric patients, correlating the MR findings with those obtained with other radiological studies. The lesions were detected in three patients, two boys and one girl, ranging in age between 10 and 14 years. The nature of the lesion was confirmed histologically in all three cases. The MR images were obtained using superconductive units at 0.5 Teslas, with T1 and T2-weighted spin-echo and STIR sequences. In two patients, gadolinium-enhanced T1-weighted images were also obtained. As in any process of maturation, the proliferation/maturation ratio depends on the moment in the course of the lesion, which affects its MR features,. In acute phases, the soft tissue mass with an intraosseous, perilesional adematous reaction predominates, while annular calcification and lesser edema are characteristic of subacute episode. Myositis ossificans is very rare in children. The inflammatory response may present a radiological pattern difficult to distinguish from that of aggressive tumor or infection, especially in the acute phase. (Author) 7 refs

Initially, the bony mass was soft and movable, but during the first year it became hard and fixed. The patient had no history of trauma. Because the lesion did not grow or cause any symptoms, the patient did not come to the hospital until 4 years after she first noticed the lesion. Radiologically, the bony mass had features characteristic of mature myositis ossificans, showing ''eggshell'' ossification. A nonmineralized soft tissue mass occurred between the surface of the radius and the bony shell. Histologically, a high-grade osteosarcoma was present between the surface of the radius and the well-differentiated bone tissue, which included fatty and hematopoietic marrow. All the findings indicated that our patient had an extremely rare case of malignant transformation of myositis ossificans. (orig.)

  14. Fibrodysplasia ossificans circumscripta of the masseter muscle.

    Geist, J R; Bhatti, P; Plezia, R A; Wesley, R K

    1998-05-01

    Fibrodysplasia ossificans circumscripta (FOC) is a lesion characterized by localized calcification of the investing fascia of skeletal muscle. It is often related to repeated trauma and was formerly known as traumatic myositis ossificans. Surgical procedures involving muscles are also believed to be a factor in the origin of the lesion. When FOC develops in the muscles of mastication it can lead to severe trismus. A case is reported of FOC in the left masseter muscle of a 44-year-old man who presented with marked limitation of opening. It was believed that previous fractures of the left maxilla and mandible and/or the subsequent surgical treatments were responsible for the onset of FOC. The radiographic and microscopic features of FOC are discussed in relation to recent theories on the etiology, pathogenesis, and treatment of the lesion.

    2008-04-01

    Full Text Available Abstract Background The t(6;8 translocation found in rare and agressive myeloproliferative disorders results in a chimeric gene encoding the FOP-FGFR1 fusion protein. This protein comprises the N-terminal region of the centrosomal protein FOP and the tyrosine kinase of the FGFR1 receptor. FOP-FGFR1 is localized at the centrosome where it exerts a constitutive kinase activity. Results We show that FOP-FGFR1 interacts with the large centrosomal protein CAP350 and that CAP350 is necessary for FOP-FGFR1 localisation at centrosome. FOP-FGFR1 activates the phosphoinositide-3 kinase (PI3K pathway. We show that p85 interacts with tyrosine 475 of FOP-FGFR1, which is located in a YXXM consensus binding sequence for an SH2 domain of p85. This interaction is in part responsible for PI3K activation. Ba/F3 cells that express FOP-FGFR1 mutated at tyrosine 475 have reduced proliferative ability. Treatment with PI3K pathway inhibitors induces death of FOP-FGFR1 expressing cells. FOP-FGFR1 also recruits phospholipase Cγ1 (PLCγ1 at the centrosome. We show that this enzyme is recruited by FOP-FGFR1 at the centrosome during interphase. Conclusion These results delineate a particular type of oncogenic mechanism by which an ectopic kinase recruits its substrates at the centrosome whence unappropriate signaling induces continuous cell growth and MPD.

    Nontraumatic myositis ossificans circumscripta (MOC) is a rarely reported benign heterotopic ossification characterized by the aberrant formation of bone in extraskeletal soft tissues. Although a history of trauma can be elicited in 75% of MOC patients, the etiology is unclear in patients without inciting injury. MOC is associated with young male athletes, and is most often localized to the muscle groups of the extremities. Rare cases have been reported in children and adolescents of nontraumatic MOC in the neck. We present a 15-year-old adolescent with a rapidly growing, painful neck mass without traumatic stimulus.

  19. Myositis ossificans imaging: keys to successful diagnosis

    Lacout, Alexis; Jarraya, Mohamed; Marcy, Pierre-Yves; Thariat, Juliette; Carlier, Robert Yves

    2012-01-01

    Myositis ossificans (MO) is an inflammatory pseudotumor of the muscle that may be mistaken clinically and even histologically for a malignant soft tissue tumor. The aim of this article is to report the imaging characteristics of MO, the emphasis being on the early diagnostic clues. USG can be used at an early stage to reveal the ‘zone phenomenon,’ which is highly suggestive of MO. A short course of nonsteroidal anti-inflammatory drug therapy may be an efficient treatment for early MO

  20. Myositis ossificans and the three-phase bone scan

    Drane, W.E.

    1984-01-01

    Myositis ossificans circumscripta (or paraosteoarthropathy) in paraplegics has been a well known entity since its classic description in 1918 by Dejerine and Ceillier. The disease is characterized by ectopic bone formation, primarily occurring in the particular soft tissues of the hips and knees. Hypotheses concerning its origin have been proposed, but its etiology is still unknown. Myositis ossificans can occur after traumatic injury, but develops in paraplegics without apparent injury in the involved regions. Radionuclide techniques have been used in the evaluation of myositis ossificans, particularly with serial studies to stage the activity of the disease. The author reports a case of myositis ossificans in a paraplegic that emphasizes the benefit of the three-phase bone scan in the early diagnosis of this disorder

  1. MYOSITIS OSSIFICANS TRAUMATICA IN A VAMPIRE BAT (DESMODUS ROTUNDUS).

    Hausmann, Jennifer C; Manasse, Jorden; Churgin, Sarah; Steinberg, Howard; Clyde, Victoria L; Wallace, Roberta

    2016-09-01

    A 15-yr-old sexually intact female vampire bat ( Desmodus rotundus ) was diagnosed with myositis ossificans traumatica of the abdominal wall. The bat presented with a large ulcerated firm mass along the abdomen. Radiographs and cytology were performed, followed by surgical exploration. The mass was determined to be nonresectable and the bat was euthanized. Histopathology showed severe necrotizing, degenerative, and pyogranulomatous myositis with osseous and cartilaginous metaplasia, fibrosis, and ulceration, which were consistent with myositis ossificans traumatica. Myositis ossificans traumatica is commonly associated with previous trauma to skeletal muscle. Two years prior, this bat had an emergency Caesarian section at this site, which was postulated to elicit a marked tissue response leading to this condition. Myositis ossificans traumatica is infrequently reported in humans, dogs, cats, pigs, and horses. To the author's knowledge, this is the first report of this condition in a bat.

  2. Merits of magnetic resonance imaging (MRI) for the diagnosis of myositis ossificans circumscripta. Apport de l'imagerie par resonance magnetique (IRM) dans le diagnostic de la myosite ossifiante circonscrite (MOC)

    Bouchardy, L.; Garcia, J. (Hopital Cantonal Geneve, Geneva (Switzerland))

    1994-02-01

    A retrospective study of 5 cases, 4 of myositis ossificans circumscripta (MOC) and 1 of non-ossificans myositis, is presented. The clinical presentation was a painful soft-tissues swelling, and the final diagnosis was established by biopsy in 3 cases and clinical evolution in 2 cases. Different types of imaging techniques were performed: 4 MRI, 2 arteriographies, 3 Tc 99m scintigraphies, 3 US, 3 CT and plain film radiographs for all patients. MOC is a benign process (as opposed to myositis ossificans progressiva, which is an hereditary pathology with a fatal prognosis) with 3 phases of evolution: an acute or pseudo-inflammatory phase, a sub-acute or pseudo-tumoral phase and a chronic phase with a spontaneous healing. The radiologic diagnostic findings are dependent of the phase of the disease. The calcifications are seen earlier with scintigraphy than plain films, with US being less helpful. A heterogenous mass and calcifications are seen with CT. MRI allows the characterization of oedema during the acute phase and sometimes can exclude a malignant process. MRI is the best method for an early diagnosis, the differential diagnosis and to follow the evolution. (authors). 26 refs., 8 figs.

  3. Pseudomalignant myositis ossificans involving multiple masticatory muscles: Imaging evaluation

    Kamalapur, Muralidhar G; Patil, Pritam B; Joshi, Shyamsundar; Shastri, Dinesh

    2014-01-01

    Myositis ossificans is a rare cause of trismus. We present a case of pseudomalignant myositis ossificans involving medial pterygoid, lateral pterygoid, and temporalis muscles. Patient presented with gross limitation in mouth opening. There was no history of trauma. Computed tomography (CT) images revealed a bone density mass located in the region of medial and lateral pterygoid muscles on the right and temporalis muscle on the left. Magnetic resonance imaging (MRI) showed similar findings. Radiological diagnosis was pseudomalignant myositis ossificans. The masses were resected and histopathologic examination confirmed the above diagnosis. This report describes the characteristic CT and MRI features. The unique feature of this case is the absence of history of trauma with involvement of multiple masticatory muscles, which, to the best of our knowledge, has not been reported before

  4. Myositis ossificans with atypical clinical, radiographic, or pathologic findings

    Nuovo, M.A.; Chumas, J.; Ackerman, L.V.

    1992-01-01

    Myositis ossificans is a relatively rare, well-defined entity. The 23 cases sent for consultation to two of us (L.V.A. and A. N.) were reviewed. Clinical, radiologic, and microscopic information was reexamined, and special attention was given to features infrequently seen in typical myositis ossificans. Due to the uncommon location of 15 lesions and an unusual presentation in 5, the correct diagnosis was not obvious in these cases. Radiologic studies raised the possibility of a malignant bone-forming tumor in at least three instances; myositis ossificans was originally diagnosed in 6 cases radiologically. In 8 cases, histologic evidence suggested malignancy, including osteosarcoma, either parosteal or extraosseous, in 6. Other diagnoses included epithelioid sarcoma and callus formation. Presentation of these variations from the norm highlights the importance of recognizing the evolution of a nonneoplastic fibro-osseous and cartilaginous entity in which conservative treatment is curative.

    Fibrodysplasia ossificans progressive is a rare hereditary connective tissue disease characterized by disseminated soft tissue ossification and congenital abnormality of the extremities. It is genetically inherited as a dominant trait with complete penetrance but variable expression. The onset takes place during childhood and the progressive involvement of the spine and proximal extremities leads to immobilization and articular deformity. We report a case of a 22-year-old male patient with typical symptoms of fibrodysplasia ossificans progressive and discuss the new advances in the diagnosis and pathophysiology. (author)

  6. Gallium uptake in myositis ossificans. Potential pitfalls in diagnosis

    Salzman, L.; Lee, V.W.; Grant, P.

    1987-01-01

    Seven cases of gallium uptake in myositis ossificans are described. Gallium scans are done frequently in paraplegics, quadriplegics, and comatose patients to look for occult infection. It is important to be aware of possible gallium uptake in myositis ossificans, particularly in the extremities, which is frequent in these patients. Gallium uptake may be present prior to any abnormalities seen on plain films or CT scans. It is important to correlate roentgenograms with abnormal gallium scans, particularly in the extremities, to avoid potential pitfalls in diagnosis and prevent unnecessary antibiotic treatment. A bone scan should be obtained whenever possible, particularly when roentgenograms are negative, to confirm the diagnosis

  8. Regional blood flow in experimental myositis ossificans

    Hierton, C.

    1983-01-01

    In a recent model for heterotopic bone formation, muscular oedema, swelling and necrosis is seen in the quadriceps muscle of rabbit hind limbs immobilized for at least 2 weeks when, from the second week, the immobilized limb is subjected to dayly forcible mobilization lasting about 5 min. According to this model, heterotopic calcification develops gradually from the second week of forcible mobilization and is located in the vastus intermedius region. Between the fourth and fifth week of immobilization and forcible mobilization, heterotopic bone formation is seen in virtually all cases. The histological findings are similar to those in human ectopic bone formation. In the present investigation the labelled microsphere technique was used to study the regional blood flow effects in the early development of myositis ossificans with this model. The results are quite different from those reported by other investigators on immobilization alone and point to a causal relation between regional blood flow and forcible mobilization of the immobilized rabbit hind limp. Prostaglandins as mediators between the traumatic inflammation, a part of the circulatory effects observed and the induction of a new bone is suggested. (author)

  9. Magnetic resonance imaging of myositis ossificans: Analysis of seven cases

    De Smet, A.A.; Norris, M.A.; Fisher, D.R.

    1992-01-01

    Since magnetic resonance imaging (MRI) is commonly used to evaluate soft tissue masses, we analyzed eight MR examinations in seven patients with myositis ossificans to determine if typical patterns were present. One acute lesion had homogeneous intermediate signal intensity on T1-weighted images and high signal intensity on T2-weighted images. Two subacute lesions had low signal intensity margins with slightly increased signal intensity centers on T1-weighted images and very high signal intensity on T2-weighted images. Five chronic lesions had two different patterns. All five were well-defined with low signal intensity borders. Three had signal intensity patterns characteristic of fat on T1-weighted and T2-weighted images. The other two lesions had intermediate signal intensity on T1-weighted images and slightly increased signal intensity on T2-weighted images. We conclude that typical MR appearances of myositis ossificans do exist. A low signal intensity rim is a common finding. However, these patterns are not unique to myositis ossificans and resemble those that have been reported in other lesions. It is important to be aware of the spectrum of MR findings of myositis ossificans when considering the differential diagnosis of a soft tissue mass. (orig./MG)

    We present a case of intraarticular myositis ossificans in the right knee of a child. Myositis ossificans (MO), though relatively rare in childhood and even more uncommon within a joint, should be included in the differential diagnosis of an intra-articular mass when indicated by the typical clinical, radiographic, and histologic findings. An 11-year-old male presented with a history of trauma to his right knee. Four weeks after the initial injury, an MRI demonstrated evidence of an ACL rupture with a ''cystic mass'' within the intercondylar notch along the anterior surface of the torn ligament. At subsequent arthroscopy, the mass noted on MRI was removed. The histology was consistent with MO. The authors believe this to be the first case of MO in the intercondylar notch detected by MRI, treated by arthroscopy, and confirmed by histology. (orig.)

    2014-12-01

    Myositis ossificans traumatica is an unusual complication following a muscle contusion injury. A significantly large myositic mass causing ankylosis of the elbow is even rarer. We report a 13-year-old boy who presented with a 14-month history of a fixed elbow with no movement and a palpable bony mass in the anterior aspect of the elbow. He had sustained significant trauma to the affected limb 1 month prior to onset of symptoms, which was managed by native massage and bandaging for 4 weeks. The clinicoradiological diagnosis was suggestive of myositis ossificans, and the myositic mass was completely excised. Histopathology revealed lamellar bone. The 2-year follow-up showed full function of the affected limb and no signs of recurrence. We report this case of clinical interest due to the unusually large myositic mass.

    Introduction: Myositis ossificans circumscripta is a benign non neoplastic ossifying tumor presenting with bone like osteoid tissue extraskelletaly amidst the muscle planes. This condition when not associated with trauma is very trivial and considering the way it mimics certain characteristics, it may be misunderstood as a malignant neoplasm, abscess or antibioma. The aetiology of this atraumatic condition is still indistinct and remains a question unsolved. We would like to report such a cas...

  17. Advantages and Limitations of the Front-of-Package (FOP Labeling Systems in Guiding the Consumers’ Healthy Food Choice

    Angela Tarabella

    2013-02-01

    Full Text Available In the last decades, nutrition labels have provided an increasing amount of information about the nutritional value of a foodstuff, in a variety of patterns, having the main goal to help consumers in making healthier food choices. Now, many questions appeared related to the effectiveness of nutrition information in guiding the consumer purchasing behaviour, by encouraging the healthy foods choice. It becomes increasingly clear that many consumers have difficulties in understanding the nutritional information, preferring a simpler way in providing this information, helping them in the rapid evaluation of the nutritional characteristics of a foodstuff. In response to the obvious need to develop a more effective presentation of nutritional information, which convey this information in a simplified and systematic manner, manufacturers and retailers from different countries have created some systems for signalling the nutritional profile. For the nutritional information of greatest interest to be easily perceived by consumers, they have used various forms of graphical representation, that were marked on the front of individual packages (generically called "front of package" - FOP. Although created in order to facilitate healthy food choices, the effect of these FOP systems on consumers is now controversial. Following a literature review, the paper highlights the main benefits and limitations of the widely used FOP systems in the European Union ("Traffic Light" and "Guideline Daily Amounts". The paper presents also some suggestions for developing an optimal FOP system, standardized and adapted to consumers` needs.

    Myositis ossificans is a benign, self-limiting and non-neoplastic development of heterotopic bone in skeletal muscle following trauma. Although myositis ossificans can occur anywhere in the body, psoas muscle involvement is very rare. To the best of our knowledge, CT and MR imaging findings of myositis ossificans in the psoas muscle secondary to lumbar spine fracture have not been reported in the radiological literature. In this article, we describe the CT and MR imaging findings of myositis ossificans of the psoas muscle after lumbar spine fracture in a 64-year-old man, and conduct a review of the relevant literature

  20. Myositis ossificans: radiologic evaluation of two cases with diagnostic computed tomograms

    Zeanah, W.R.; Hudson, T.M.

    1982-01-01

    Although most physicians associated myositis ossificans with recent, acute trauma, only 40%-60% of patients give such a history. The appearance of a soft tissue mass without a clear history of trauma may suggest a diagnosis of sarcoma, especially because results of a biopsy of the central portion of an area of myositis ossificans may yield immature, undifferentiated tissue resembling a sarcoma. Pain and rapid growth of a mass are more usual in myositis ossificans than in sarcomas, and careful inquiry may reveal stretching injury or chronic trauma associated with normal, vigorous, physical activities. Recognizing the characteristic histologic zoning phenomenon (immature tissue centrally surrounded by more mature tissue and a peripheral shell of benign bone) during the biopsy procedure permits the correct diagnosis of myositis ossificans. Plain radiographs or conventional tomograms may reflect this histologic zoning by demonstrating the typical, mature, outer shell of bone. Although additional radiographic studies are not usually necessary, they may be obtained when the mass is suspected to be a sarcoma. In two patients computed tomographic scans clearly demonstrated well-defined, peripheral shells of mature bone, diagnostic of myositis ossificans

    To report clinical signs, diagnostic imaging findings, and outcome in a dog with traumatic myositis ossificans of the origin of the extensor carpi radialis muscle. Clinical report. An 8-month-old intact female Irish Setter Dog. After radiographic and computed tomographic evaluation of an osseous proliferation arising from the cranial cortex of the right distal humeral diaphysis, the protruding bone was surgically removed and evaluated by histopathology. Traumatic myositis ossificans was successfully treated with surgical removal of the osseous proliferation resulting in improved postoperative range of motion of the right elbow joint. There was no evidence of lameness or abnormal bone regrowth associated with the surgical site radiographically at follow up. Surgical removal of a traumatic myositis ossificans lesion resulted in full return to function in a young, competitive show dog. © Copyright 2014 by The American College of Veterinary Surgeons.

    Full Text Available Niemann-Pick Disease (NPD is a rare autosomal recessive lysosomal lipid storage disorder. The disease is caused by gene mutations that affect the metabolism of sphingolipids. The dysfunctions cause sphingomyelin to accumulate in different organs. NPD includes forms with low and high levels of sphingomyelin. We report a case of a 34 year-old man with a family history of NPD type B who presented with hepatosplenomegaly, neurological deficiency, bone abnormalities, and myositis ossificans. The clinical, biochemical, and imaging data confirmed the combined diagnosis of NPD type B with myositis ossificans.

  3. An unusual case of lumbar paravertebral miositis ossificans mimicking muscular skeletal tumor.

    2013-12-01

    Several lesions have clinical and radiological characteristics mimicking muscular skeletal tumor. Myositis ossificans usually presents a typical pattern making biopsy unnecessary; nevertheless, in rare cases, neoplasm must be ruled out. Biopsy is often sufficient to allow a diagnosis and a correct related treatment, but, unfortunately, sometimes it may lead to erroneous treatment. We report an unusual case of a lumbar paravertebral mass that had an MRI aspect similar to a chondrosarcoma, a histology pattern based on biopsy compatible with neurinoma and a definitive diagnosis of myosistis ossificans.

    The association between sensorineural hearing loss and sickle cell disease has been described, and labyrinthine hemorrhage has been reported with sickle cell disease. We report the CT and MRI findings of labyrinthitis ossificans in a child with sickle cell disease who presented with sensorineural hearing loss. Labyrinthitis ossificans is associated with an infectious, inflammatory, or destructive insult to the membranous labyrinth; however, it has not been specifically described with sickle cell disease. Recognition of this condition is important because it affects both management and prognosis of this disease. (orig.)

  5. Myositis ossificans around shoulder following military training programme

    Mustafa C Kir

    2011-01-01

    Full Text Available The myositis ossificans around shoulder in military recruits are not reported yet. Three young male soldiers presented with complaints of palpable mass at the anterior aspect of shoulder; tenderness around the superior part of deltopectoral groove close to acromioclavicular joint; and restriction of shoulder motion. They also noticed ecchymosis and pain around the coracoid process and anterior shoulder region during regular firing exercises. Plain X-rays and computerized tomography showed extra-capsular, dense, irregular structure in the space between pectoralis and deltoid muscles which correlated with heterotopic bone. One patient refused surgical intervention because of the completion of his military serving period. Surgical excision was performed for the other two patients. During surgical exploration, both ossified masses were found in deltopectoral region and mostly in fibers of clavicular and acromial parts of deltoid muscle. Pathological reports confirmed the structure of masses as mature trabecular bone. Postoperatively indomethacin treatment and active shoulder exercises were started until the full range of motion was regained. Mini soft bag was used on the rifle contact area of the shoulder. No complications or recurrences were observed during the 24 months of followup period.

    Full Text Available OBJETIVO: Descrever os resultados imediatos e tardios da cirurgia para correção de escoliose em pacientes com amiotrofia espinhal progressiva (AEP. MÉTODO: 14 pacientes com AEP submetidos a cirurgia para escoliose foram selecionados para análise retrospectiva dos prontuários e radiografias, assim como para exame radiográfico e aplicação de um questionário na consulta final. O tempo médio de seguimento foi de 22 meses. A escoliose média pré-operatória foi de 78,4° pelo método de Cobb. Todos os pacientes apresentavam obliqüidade pélvica (média de 25,5° e 11 apresentavam cifose. A média de idade à época da cirurgia foi de 12 anos e 3 meses. Em 12 pacientes foi realizada artrodese via posterior com instrumental de Luque-Galveston, e em 2 com instrumental de Cotrel-Dubousset. RESULTADOS: Foi obtida correção no pós-operatório imediato de 64,3% da escoliose, 36,4% da cifose e 70,9% da obliqüidade pélvica. As complicações foram fístula liquórica e infecção precocemente em um caso; e tardiamente soltura da amarria de T1, em dois casos. Houve perda média de correção no final do seguimento de 0,26° da escoliose e de 1,28° da obliqüidade pélvica. Os pais e os pacientes referiram boa melhora em relação aos aspectos estéticos, postura, equilíbrio para sentar e cuidados de higiene, assim como das intercorrências respiratórias. CONCLUSÃO: A cirurgia para escoliose na AEP tem impacto satisfatório quanto à estética, qualidade de vida e função respiratória dos pacientes, com mínima perda da correção obtida com o tempo e com poucas complicações.

    Fear of cancer progression/recurrence (FOP/FCR) is considered one of the most prevalent sources of distress in cancer survivors and associated with lower quality of life and functional impairment. Detailed measures of FOP/FCR are needed because little is known about the knowledge of FOP/FCR, its associations with the patient-doctor relationship, and the rate of adequate therapy. Colorectal cancer (CRC) is one of the most prevalent cancer entities, and oral capecitabine is widely prescribed as treatment. Therefore, we initiated a pilot study to expand the literature on FOP/FCR in CRC outpatients receiving capecitabine and to generate hypotheses for future investigations. This study included 58 patients treated at a comprehensive cancer center. FOP/FCR was assessed with the Fear of Progression Questionnaire (FOP-Q-SF). Satisfaction with the relationships with doctors was assessed with the Patient-Doctor Relationship Questionnaire-9 (PRDQ-9). Levels of side effects were rated by the patients on a visual analog scale. Clinical data were extracted from the charts. A total of 19 out of 58 patients (36%) suffered from FOP/FCR according to our assessment. Levels of FOP/FCR seemed to be mostly moderate to high. Only four out of the 19 distressed patients (21%) were treated accordingly. Typical side effects of oncological treatment were associated with higher FOP/FCR. Satisfaction with doctor-patient relationships was not associated with FOP/FCR. Regarding single items of FOP/FCR, three out of the five most prevalent fears were associated with close relatives. FOP/FCR occurred frequently in more than one in three patients, but was mostly untreated in this sample of consecutive outpatients with CRC receiving oral capecitabine. In detail, most fears were related to family and friends. In addition to an unmet need of patients, our data indicate sources of distress not considered thus far. If replicated in larger studies, results may help to inform intervention development and

  9. A fatal case of metastatic squamous cell carcinoma in a patient with myositis ossificans traumatica.

    Vlasveld, I N; Scheper, H; Stalenhoef, J; Baas, J M; van Dissel, J

    Myositis ossificans traumatica is a rare disease associated with chronic wounds and fistulae. Chronic ulcers, fistulae and wounds can transform into squamous cell carcinoma, the so-called Marjolin's ulcer. We describe a rapid, progressive and fulminant course of a metastatic squamous cell carcinoma

  10. Non-traumatic myositis ossificans mimicking a malignant neoplasm in an 83-year-old woman: a case report

    Full Text Available Abstract Introduction Myositis ossificans is a benign, self-limiting condition that usually affects young, athletically active men. To the best of our knowledge, this case report describes the oldest recorded patient with myositis ossificans. Case presentation Our patient was an 83-year-old Japanese woman who presented with a one week history of a palpable mass in the left thigh. She had a history of surgery for transverse colon cancer and lung cancer at the ages of 73 and 80, respectively. Clinical and radiological examinations suggested a malignant neoplasm such as metastatic carcinoma or extraskeletal osteosarcoma. A diagnosis of myositis ossificans was made by core needle biopsy. Our patient was asymptomatic and had no recurrence at one year follow-up. Conclusion Clinicians should consider myositis ossificans as a possible diagnosis for a soft tissue mass in the limb of an older patient, thereby avoiding unnecessarily aggressive therapy.

  11. MR imaging and ultrasonography findings of early myositis ossificans: a case report

    Lee, Kyung Ryeol; Park, So Young; Jin, Wook; Won, Kyu Yeoun

    2016-01-01

    Myositis ossificans (MO) is a benign soft tissue lesion with non-neoplastic heterotopic bone formation. MO in the intermediate and mature stages can be easily diagnosed if characteristic imaging findings such as a peripheral zonal pattern of ossification with variable thickness is observed. However, it is difficult to correctly diagnose early MO because it can mimic malignancy clinically, radiologically, and histopathologically. We report a case of early pseudosarcomatous phase of non-traumatic MO with atypical imaging findings. A 59-year-old woman presented with pain followed by a mass in the left thigh within a week. MR imaging and ultrasonography showed an intramuscular lesion with preserved muscle fascicles in the vastus lateralis muscle. Intralesional ossification or calcification was not seen on ultrasonography. A diagnosis of myositis ossificans was made by ultrasonographically guided biopsy. (orig.)

    1993-01-01

    We present the case of a 4-year-old female with a complex fracture of the left hemipelvis who, on follow-up CT imaging, developed new ossific densities within the peripelvic soft tissues of the contralateral side. Three-dimensional surface reformations of the pelvis demonstrated myositis ossificans along the course of the right sacrospinous ligament, thus elucidating unsuspected ligamentous injury and implying prior instability.

    1987-01-01

    A case of heterotopic ossification (myositis ossificans) secondary to the central nervous system complications of acquired immune deficiency syndrome (AIDS) is reported. Because of the overwhelming suspicion of infection in this patient, this diagnosis was not considered until a gallium scan revealed the typical findings of heterotopic ossification. Because of the increasing utilization of gallium imaging in the AIDS population, every imaging specialist should be aware of this potential disorder

    1995-01-01

    The authors report a case of ossificans myositis, in which magnetic resonance imaging (MRI) showed inflammatory changes of the adjacent bone. T 1 weighted fat saturation sequence with gadolinium injection showed enhancement of medullary and cortical bone. This potentially mistaking pattern must be known, to avoid mis diagnosing with malignant osseous tumor, specially before achievement of the characteristic pattern of zonal maturation and its calcified rim.

    1984-01-01

    Myositis ossificans is primarily a disorder of young adults, whereby an area of muscle mass undergoes progressive ossification. The authors review a case in which the patient's presentation was somewhat atypical, and where the course of disease was unusually prolonged. Examination of the soft tissue lesion using Tc-99m diphosphonate bone scans was helpful in establishing the diagnosis and in determining the full extent of the process early in its evolution

  18. Case report 488: Post-traumatic myositis ossificans mimicking a soft tissue neoplasm

    Ackerman, L.; Ramamurthy, S.; Jablokow, V.; Van Drunen, M.; Kaplan, E.

    1988-01-01

    A case of post-traumatic myosotis ossificans (MO) in a young man with only a vague history of preceding physical trauma to the area of the lesion was presented. Imaging modalities, including plain film radiography, CT, contrast angiography and bone scintigraphy, could not exclude a malignancy with a reliable degree of certainty. The biopsy specimen was consistent with MO but could easily be misinterpreted as a sarcomatous lesion. A diagnosis of MO was only established by a scrupulous analysis of all clinical, radiological, scintigraphic and microscopic findings and unnecessary extensive surgery for a malignancy was avoided. The correlative radiological and pathological features in distinguishing post-traumatic myositis ossificans from such lesions as soft tissue osteosarcoma or parosteal osteosarcoma were described and the meaning of the term zoning phenomenon was elucidated. It was emphasized that utilizing the zonal phenomenon (both pathologically and radiologically) ensures a correct diagnosis most of the time. However, it must be emphasized that this zoning phenomenon is not established in the early stages of post-traumatic myositis ossificans. (oerig./MG)

    Gu Xiang; Bai Rongjie; Qu Hui; Cheng Xiaoguang; Li Yuang

    2009-01-01

    Objective: To investigate the MRI features of myositis ossificans, and to address the correlation with X-ray radiography and CT findings. Methods: X-ray films, CT and MRI of 36 documented cases of myositis ossificans were retrospectively analyzed, and the literatures were reviewed. Results: Of the 36 cases, 4 cases occurred in the elbow joint, 4 in the shoulder joint, 15 in the hip joint, 6 in the tibiofibula, 5 in the femur, 1 in the metatarsal bones, and 1 in the ilium, respectively. Irregular patchy or lamellar high density calcification or ossification could be seen in the soft tissue parenchym on X-ray films and CT scan. Cortical bone integrity was preserved in diaphysis. CT enhanced scan showed that the swollen parenchyma was not enhanced and there was no parenchyma mass. On the early and middle stages, MR T 1 WI and T 2 WI showed slice-shaped low signal in the peripheral parenchyma, but patchy high signal was found around the low signal on T 2 WI. STIR showed mixed high and low signals in the swollen parenchyma with unclear demarcation. The lesions showed low signal on MR T 1 WI and T 2 WI in the late stage, and there was no edema in peripheral parenehyma. MRI enhanced scan found that the swollen parenchyma showed no enhancement in all stages. Conclusions: The imaging features of myositis ossificans have some characteristics. Misdiagnosis could be avoided when the disease was evaluated with the course. (authors)

    Full Text Available OBJETIVO: Compreender, por meio de figuras e funções matemáticas do cone, as lentes progressivas e mostrar que elas não são lentes multifocais porque, nelas, a refração da luz não obedece as leis da geometria euclidiana. MÉTODOS: Foi feito um estudo da geometria analítica do cone, com o programa de computador Auto-CAD 14, dando enfoque óptico às figuras geométricas obtidas com a sua secção. RESULTADOS: Pela análise das figuras obtidas da secção do cone, pudemos observar as superfícies que compõem as lentes progressivas. Estas superfícies são compostas de elipse, círculo, parábola e hipérbole. Diferente do que é dito na literatura, encontramos as elipses com diâmetro maior nas ordenadas e de mesmo sentido seguida por duas superfícies inferiores que são parábola e hipérbole e não o contrário. CONCLUSÕES: As lentes progressivas diferentemente das lentes multifocais apresentam prismas nos centros ópticos como decorrência da sua estrutura. No final, fizemos análise das suas formas mostrando o limite teórico da sua evolução.

  1. Heterotopic bone formation (myositis ossificans) and lower-extremity swelling mimicking deep-venous disease

    Orzel, J.A.; Rudd, T.G.; Nelp, W.B.

    1984-01-01

    A quadriplegic patient with a swollen leg was suspected of having deep-venous thrombosis, and was studied with radionuclide venography (RNV) and contrast venography. Focal narrowing of the femoral vein, seen on RNV, was due to extrinsic compression. Although soft-tissue radiographs were normal, Tc-99m diphosphonate imaging established the diagnosis of early heterotopic bone formation (myositis ossificans), which was responsible for the venous compression. Clinically this inflammatory process can mimic deep-venous thrombosis, and should be considered in evaluating patients at risk for both heterotopic bone formation and deep-venous thrombosis

    2011-01-01

    Myositis ossificans circumscripta (MOC) is a rare benign neoplasm located in soft tissues that, most of the time, appears after a local trauma. The positive diagnosis of MOC may be challenging on CT or MRI findings. We report on an atypical case of a spontaneous nontraumatic MOC in a 54-year-old man, located in the longus supinatus muscle diagnosed with MRI and F-18 FDG PET/CT findings. Rarely described F-18 FDG PET/CT features in MOC are presented. Pattern of avid FDG focus on PET/CT, that may wrongly suggest osteosarcoma, is presented.

  4. A case of myositis ossificans in the upper cervical spine of a young child.

    Findlay, Iain; Lakkireddi, Prabhat Reddy; Gangone, Ravinder; Marsh, Gavin

    2010-12-01

    Case report. We present a case of myositis ossificans (MO) of the upper cervical spine in a young child. The literature is reviewed with the classification, etiology, and treatment of MO discussed. Calcification of joint capsule, muscle, cartilage, and ligaments is a well-known phenomenon and is known as myositis ossificans. It is very rarely seen in the head and neck, with no reports of MO of the soft tissues surrounding the first 2 cervical vertebrae. An 8-year-old boy presented with severe neck pain after a fall. He had had a similar neck injury 4 years before, but made a full recovery. Radiographs showed a large ossified lesion between the posterior elements of C1 and C2. After further imaging, a diagnosis of MO was made. The child was treated with simple analgesia and observation. With no evidence of neurologic compromise and minimal symptoms, there was no indication for surgical intervention. Although rare, MO should be suspected as one of the possible causes of persistent pain following cervical spine injury in children. We would advise a low threshold for cervical spine imaging in the child presenting with persistent neck pain and stiffness, even years after injury.

  5. Myositis ossificans circumscripta of the psoas muscle due to overuse in an adolescent gymnast.

    Masquijo, Julio Javier; Sartori, Federico

    2014-11-01

    Myositis ossificans is a pseudoinflammatory tumour that originates from skeletal muscle and corresponds to a heterotopic, metaplastic, nonmalignant bone tumour. The purpose of this article is to report the case of myositis ossificans circumscripta (MOC) of the psoas muscle due to overuse in an adolescent gymnast. A 16-year-old female athlete presented at our outpatient orthopaedic clinic for evaluation of a 1-month history of low back pain. Initial plain radiographs were initially interpreted as negative, and laboratory values were normal. MRI imaging demonstrated a circumscribed mass with associated oedema in the psoas muscle. Computed tomography-guided percutaneous biopsy was performed and histology confirmed the diagnosis of MOC. Conservative treatment was initiated with rest and anti-inflammatory drugs (indomethacin). The patient had a resolution of pain and function after 3 months of conservative treatment. At 6 months' follow-up, MRI demonstrated complete resolution of the lesion and she gradually returned to her sports activity. At last follow-up she was asymptomatic. MOC is a rare lesion in the paediatric-adolescent population. To our knowledge, this is the first report of MOC in the psoas muscle produced by overuse. MRI is very sensitive in detecting oedema during the acute phase of the lesion. Conservative treatment should be considered, especially at the early stage of the disease. Spontaneous resolution can be expected in most cases.

    2000-01-01

    Myositis ossificans traumatica (MOT) is a rare musculoskeletal disorder in young children. Clinical and imaging presentation in the early stage of disease makes it difficult to differentiate between infection and musculoskeletal neoplasms, particularly in the absence of a history of trauma. Three cases of MOT in children under the age of 10 years, two with inferential trauma, are presented and the findings on different imaging modalities are discussed with reference to the existing literature. While findings based on a single imaging technique, including MRI, may be rather non-specific and even misleading, the combination of different modalities can assist in the consideration of MOT as a possible diagnosis. For example, the demonstration of soft-tissue haematoma on US would suggest the traumatic origin. A rational imaging approach is proposed. (orig.)

    Myositis ossificans (MO) is a rare benign cause of heterotopic bone formation within soft tissue. It most commonly affects adolescents and young adults, typically in the limbs and following trauma. Very few cases have been reported in children. We report here a case of nontraumatic MO occurring in a 10-year-old girl with an uncommon location in the 5th right intercostal space; it was initially misdiagnosed and treated as osteosarcoma. Imaging findings including plain radiographs, CT, MRI, bone scintigraphy and PET-CT are described. This case highlights the central role played by imaging in diagnosis, thus avoiding biopsy that can erroneously suggest osteosarcoma as the diagnosis, as occurred in this case. (orig.)

    1997-09-01

    Full Text Available The clinical features of the primary progressive freezing gait, a rare and distinct neurological entity, have been described in some articles. This paper describes this gait disorder affecting one patient, whose condition's long course provoked no postural instability. As stated in the literature, the pathophysiology of the primary progressive freezing gait still remains unclear, although the lack of response to levodopa therapy suggests a possible involvement of nondopaminergic pathways. Alteration in the visual perception may be a potential cause for the condition.Uma rara e distinta entidade neurológica, a marcha congelada progressiva primária, tem sido relatada na literatura. Descrevemos o caso de um paciente com este distúrbio da marcha que, apesar do longo curso da doença, não apresentava instabilidade postural. Como citado na literatura, a fisiopatologia desta condição permanece obscura, embora a falta de resposta à levodopa sugira uma possível participação de vias não dopaminérgicas. Alteração na percepção visual também pode estar envolvida na gênese desta afecção.

  11. Myositis ossificans versus osteosarcoma: Is it possible to achieve differential diagnosis by skeletal scintiscanning?

    Toman, A.; Enderle, A.; Munz, D.L.

    1989-01-01

    The authors report the cases of two juvenile patients suffering for about three weeks from a painful swelling in the humerus region, who were to be examined for suspected osteosarcoma. In one patient, the X-ray picture at that time showed a discrete solidification in the soft tissue, the findings in the other patient were normal. Three-phase skeletal scintiscanning with Tc-99m MDP in the perfusion and in the blood pool phase revealed an only slightly enhanced, localised activity accumulation in the affected area. The image taken in the late static phase revealed a clearly defined, clearly enhanced activity accumulation, which was characterised by a marginal accentuation with relatively lower accumulation of the radiopharmaceutical in the center. This characteristic pattern of activity distribution can only be detected by means of a subtle, computer-aided control system. The specific distribution pattern indicated the possibility of myositis ossificans localisata. X-ray diagnostics and especially computed tomography verified this diagnosis. (orig./MG) [de

    Myositis ossificans is a difficult differential diagnosis and a false positive for malignancy in both 99m Tc H.M.D.P. (hydroxy-methylene diphosphonate) scintigraphy and in exploration PET-F.D.G. This hypothesis should be mentioned in case of young patients, despite the unusual scintigraphic appearance in a benign process. (N.C.)

  18. Contribuição para o diagóstico diferencial da distrofia muscular progressiva

    José Antonio Levy

    1964-06-01

    Full Text Available Os dados fornecidos pela anamnese assim como a sintomatologia nem sempre permitem estabelecer, com segurança, o diagnóstico de distrofia muscular progressiva (DMP; o diagnótico é facilitado quando são obtidos dados heredológicos depondo por afecção de caráter familiar ou quando se trate de casos de longa evolução, mostrando a característica fundamental da irreversibilidade. As provas laboratoriais propostas até agora, embora úteis para a avaliação do estado da consunção do tecido muscular, não fornecem elementos seguros para o diagnóstico diferencial, pois os resultados podem ser idênticos tanto na DMP (especialmente nas fases, iniciais ou de evolução subaguda como nas polimiosites e nas neuromiosites. De grande importância para o diagnóstico diferencial são a eletromio-grafia e a biopsia muscular: a eletromiografia mostra, na DMP, diminuição da voltagem e redução da duração média dos potenciais de ação, com elevada incidência de potenciais polifásicos; o exame histológico mostra grande variação no calibre e degeneração das fibras musculares com proliferação de tecido conjuntivo, sem infiltrações de caráter inflamatório e sem atividade regenerativa útil. Entretanto, êstes exames complementares não bastam, por si sós, para o diagnóstico diferencial de todos os casos e seus resultados devem ser interpretados cuidadosamente. Neste trabalho são referidos 21 casos que exigiram cuidadoso diagnóstico diferencial. Em 17 (casos 1 a 17, com base na anamnese e na sintomatologia, fôra feito o diagnóstico de DMP; entretanto em todos êles o exame mais minucioso, acrescido de dados fornecidos pela eletromiografia e especialmente pela biopsia, conduziu à formulação de outro diagnóstico. Em dois casos (18 e 19, ambos de moléstia de Charcot-Marie-Tooth, o exame histo-patológico sugeria o diagnóstico de DMP. Em um caso (20 o quadro clínico sugeria DMP e o exame eletromiográfico indicava haver les

    The authors report a case of ossificans myositis, in which magnetic resonance imaging (MRI) showed inflammatory changes of the adjacent bone. T 1 weighted fat saturation sequence with gadolinium injection showed enhancement of medullary and cortical bone. This potentially mistaking pattern must be known, to avoid mis diagnosing with malignant osseous tumor, specially before achievement of the characteristic pattern of zonal maturation and its calcified rim.

    Full Text Available Primary progressive aphasia (PPA is an intriguing syndrome, showing some peculiar aspects that differentiate it from classical aphasic pictures caused by focal cerebral lesions or dementia. The slow and progressive deterioration of language occurring in these cases provides an interesting model to better understand the mechanisms involved in the linguistic process. We describe clinical and neuroimaging aspects found in 16 cases of PPA. Our patients underwent language and neuropsychological evaluation, magnetic resonance imaging (MRI and single photon emission computerized tomography (SPECT. We observed a clear distinction in oral expression patterns; patients were classified as fluent and nonfluent. Anomia was the earliest and most evident symptom in both groups. Neuroimaging pointed to SPECT as a valuable instrument in guiding the differential diagnosis, as well as in making useful clinical and anatomical correlations. This report and a comparison to literature are an attempt to contribute to a better understanding of PPA.A afasia progressiva primária (APP é uma síndrome que tem despertado grande interesse devido a aspectos particulares que a diferenciam das afasias clássicas (secundárias a lesões cerebrais focais e dos quadros demenciais. A deterioração lenta e progressiva da linguagem presente nesses casos fornece um interessante modelo de observação dos mecanismos subjacentes ao processamento linguístico. Descrevemos as características clínicas e de neuroimagem de 16 casos de APP. Os pacientes foram submetidos a exame de linguagem, neuropsicológico, ressonância magnética (RM e tomografia computadorizada por emissão de fóton único (SPECT. Clinicamente pudemos observar uma nítida distinção nos padrões de produção oral, sendo os pacientes agrupados em fluentes e não-fluentes. Anomia foi o sintoma mais precoce e evidente nos dois subgrupos. Os achados de neuroimagem permitem destacar a sensibilidade do SPECT como

    Full Text Available Com base em trabalhos anteriores, 13 casos de distrofia muscular progressiva foram tratados com lactato de sódio 1/6 molar associado a ATP e complexo B. O exame da força muscular, realizado antes e após o tratamento — salvo em dois casos nos quais ocorreram melhoras muito discretas — não mostrou qualquer efeito favorável da medicação. Os autores sugerem a verificação de possíveis alterações enzimáticas provocadas pelo lactato de sódio, o que serviria para melhor avaliação do efeito terapêutico.Thirteen cases of progressive muscular dystrophy were treated with 1/6 M. sodium lactate plus ATP and B complex. Examinations of muscle strength, before and after the treatment, did not show any favourable effects, except in two of the cases which showed slight improvement. The authors suggest that possible enzimatic alterations caused by the sodium lactate be checked up on, since this checking could be employed in the evaluation of the therapeutic effects.

    USP6 rearrangements with several partner genes have been identified recently in primary but not in secondary aneurysmal bone cysts (ABCs). Several lesions show histologic features that may overlap with ABC, including myositis ossificans (MO), brown tumor, and cherubism. The objective of this study was to assess whether these lesions harbored USP6 rearrangements. Twelve patients with classic radiologic and histologic features of MO, 6 with brown tumors, and 5 with cherubism diagnosed at our institution were studied for the presence of USP6 rearrangements using fluorescence in situ hybridization with probes flanking the USP6 locus on chromosome 17p13. In addition, conventional cytogenetic analysis was performed in 2 patients with cherubism. USP6 rearrangements were identified in 2 patients with radiologic and histologic features consistent with MO. None of the patients with brown tumor or cherubism demonstrated USP6 rearrangements. Cytogenetic analysis of the cherubism patients demonstrated normal karyotypes. These findings indicate that a subset of cases with apparent classic histologic and imaging features of MO are rather better classified as being soft-tissue ABC with clonal USP6 rearrangements. In contrast, no USP6 rearrangements were found in patients with cherubism or brown tumor, supporting the prevailing view that these lesions are distinct biologic entities. (orig.)

    The purpose of this case report is to describe a patient with post traumatic myositis ossificans (PTMO) of the anterior thigh following blunt trauma and discuss the incidence, clinical presentation, management, and imaging findings. An 18-year-old male presented to a chiropractic clinic with a chief complaint of left knee pain and reduced range of motion after an impact injury to his left anterior thigh during hurdling 6 weeks earlier. Immediately after the injury, he presented to the emergency department where radiography of the left knee was negative and he was diagnosed with a muscle sprain. Follow-up radiography and ultrasonography of the left knee in a chiropractic radiology department revealed ossification consistent with PTMO within his vastus intermedius. The patient underwent a course of rehabilitation for 2 months including ice, class IV cold laser and vibration applied to his anterior thigh, and myofascial release of his quadriceps musculature with targeted and progressive rehabilitative exercises. His left knee pain resolved within 2 weeks of care. He resumed sports participation (American football) pain-free, while wearing protective padding over the affected thigh, 1 month after presentation, which was approximately 2 1/2 months following his injury. This case demonstrates that ultrasonography may have the capability to detect early phases of PTMO approximately 2 weeks prior to radiographic evidence and to monitor progression throughout its course.

    Full Text Available É estudada uma forma particular de distrofia muscular progressiva — forma óculo-faríngea — cujo diagnóstico foi comprovado mediante traçados eletromiográficos e biópsia do músculo orbicular da pálpebra. São analisadas as duas formas de distrofias oftalmoplégicas: 1 miopatia ocular; 2 miopatia óculo-faríngea. A forma óculo-faríngea é mais rara, incide em idades mais avançadas (média de 40 anos em comparação com a forma ocular pura (média de 23 anos; além disso, é ressaltada a alta incidência familiar daquela forma de miopatia. O caso ora registrado parece ser um élo entre as duas formas, pois o início foi precoce, sem incidência familiar e com comprometimento da deglutição e de músculos da face, pescoço, tronco, cintura escapular, pélvica e dos membros.A case of peculiar form of progressive muscular dystrophy — the oculopharyngeal one — is reported. The diagnosis was ascertained by electromiography and biopsy of orbicularis palpebrae muscle. Two forms of ophthalmoplegic dystrophy are analysed: 1 ocular myopathy and 2 oculopharyngeal miopathy. The latter is less frequent, occurring on patients in the fourth decade, in comparison with the pure ocular form affecting patients in the second decade. Besides this, the high familial incidence of the oculo-pharyngeal form is stressed. The reported case seems to be an intermediate form between them. The onset occurred at 11 years of age; there was no other case in the family, the disease involving swallowing, face, neck, trunk, shoulder, pelvic and members muscles.

    2014-01-01

    Full Text Available A rare disease afflicts less than 200,000 individuals, according to the National Organization for Rare Diseases (NORD of the United States. Over 6,000 rare disorders affect approximately 1 in 10 Americans. Rare genetic bone disorders remain the major causes of disability in US patients. These rare bone disorders also represent a therapeutic challenge for clinicians, due to lack of understanding of underlying mechanisms. This systematic review explored current literature on therapeutic directions for the following rare genetic bone disorders: fibrous dysplasia, Gorham-Stout syndrome, fibrodysplasia ossificans progressiva, melorheostosis, multiple hereditary exostosis, osteogenesis imperfecta, craniometaphyseal dysplasia, achondroplasia, and hypophosphatasia. The disease mechanisms of Gorham-Stout disease, melorheostosis, and multiple hereditary exostosis are not fully elucidated. Inhibitors of the ACVR1/ALK2 pathway may serve as possible therapeutic intervention for FOP. The use of bisphosphonates and IL-6 inhibitors has been explored to be useful in the treatment of fibrous dysplasia, but more research is warranted. Cell therapy, bisphosphonate polytherapy, and human growth hormone may avert the pathology in osteogenesis imperfecta, but further studies are needed. There are still no current effective treatments for these bone disorders; however, significant promising advances in therapeutic modalities were developed that will limit patient suffering and treat their skeletal disabilities.

Os relatos e interpretações de comprometimento do sistema nervoso central na HFP, conforme deduzido pela ocorrência de crises epilépticas em alguns pacientes e pela documentação por pneumencefalografia e CT em pequenas séries de pacientes, são contraditórios. Examinamos três pacientes do sexo feminino com HFP, uma com epilepsia, com o objetivo de obter mais informações sobre a patogênese da doença. MÉTODOS: Realizamos exames de ressonância magnética nuclear (RMN de rotina da cabeça e face. RESULTADOS:Apenas a paciente com epilepsia apresentou achados patológicos no cérebro. Estes eram confinados ao hemisfério homolateral à hemiatrofia facial: dilatação monoventricular, dismorfismo meningo-cortical e alterações na substância branca. CONCLUSÕES: As alterações morfológicas verificadas à RMN assim como os achados neurorradiológicos e histopatológicos mostrados em revisão da literatura indicaram que a hemiatrofia homolateral é achado típico para um subgrupo de pacientes com HFP, mas não indica um modelo de simples processo atrófico. Reconsideramos a possibilidade de uma meningoencefalite crônica com acometimento vascular como possível causa do ocasional envolvimento cerebral na HFP.

    Full Text Available A radioterapia é um dos fatores desencadeantes do hipopituitarismo, mesmo quando não direcionada diretamente para o eixo hipotálamo-hipofisário, podendo resultar em redução de hormônios adeno-hipofisários, principalmente por lesão hipotalâmica. A perda da função da hipófise anterior é progressiva e geralmente na seguinte ordem: hormônio do crescimento, gonadotrofinas, adrenocorticotrofina e o hormônio estimulante da tireóide. Vários testes estão disponíveis para a confirmação das deficiências, sendo discutidos, neste artigo, os melhores testes para pacientes submetidos à irradiação. Enfatizamos que o desenvolvimento do hipopituitarismo após a radioterapia é dose e tempo dependente de irradiação, com algumas diferenças entre os eixos hipofisários. Portanto, a conscientização da necessidade de terapia em conjunto de endocrinologistas e oncologistas otimizará o tratamento e a qualidade de vida do paciente.Hypopituitarism can be caused by radiation therapy, even when it is not directly applied on the hypothalamic-pituitary axis, and can lead to anterior pituitary deficiency mainly due to hypothalamic damage. The progressive loss of the anterior pituitary hormones usually occurs in the following order: growth hormone, gonadotropin hormones, adrenocorticotropic hormone and thyroid-stimulating hormone. Although there are several different tests available to confirm anterior pituitary deficiency, this paper will focus on the gold standard tests for patients submitted to radiation therapy. We emphasize that the decline of anterior pituitary function is time- and dose-dependent with some variability among the different axes. Therefore, awareness of the need of a joint management by endocrinologists and oncologists is essential to improve treatment and quality of life of the patients.

    Full Text Available Primary progressive multiple sclerosis (PPMS is defined clinically with a progressive course from onset. There is no approved treatment for the PPMS. Methylprednisolone IV (MP hastens the recovery from MS relapses. We studied 11 patients that met the MacDonald's diagnostic criteria for PPMS. The dose of MP was 30 mg/kg in 250 mL of glucose solution in three consecutive days during the first week, two doses during the second and one dose in the third week. One weekly session for eight consecutive weeks was given. After, a once-a week/eight-week interval was maintained. The medium EDSS before treatment was 6.2, and after 11.2 years of treatment, the EDSS was 4.9. Although we studied a small sample of PPMS we may conclude that therapy with IVMP prevents clinical worsening of MS in the majority of patients with improvement in EDSS scores.A forma progressiva da esclerose múltipla (FPEM é definida como progressiva desde o início. Não há tratamento eficaz para esta forma. A metilprednisolona por via endovenosa (MPEV é usada para os surtos de exacerbação da EM. Estudamos 11 pacientes que preenchiam os critérios de MacDonald para FPMS. A dose inicial de MPEV foi de 30 mg/kg em 250 mL de soro glicosado por três dias consecutivos na primeira semana, duas doses na segunda e uma dose na terceira semana. Seguiu-se uma sessão semanal por oito semanas. Após manteve-se uma dose semanal a cada oito semanas. A média do EDDS foi 9,6 antes e 4,9 após 11,2 anos de tratamento. Embora tenhamos estudado número reduzido de casos, podemos dizer que o uso de MPEV impede a progressão da FPEM na maioria dos pacientes estudados com melhora do EDDS.

  15. Evaluation of Salivary Cytokines for Diagnosis of both Trauma-Induced and Genetic Heterotopic Ossification

    Benjamin Levi

    2017-04-01

    Full Text Available PurposeHeterotopic ossification (HO occurs in the setting of persistent systemic inflammation. The identification of reliable biomarkers can serve as an early diagnostic tool for HO, especially given the current lack of effective treatment strategies. Although serum biomarkers have great utility, they can be inappropriate or ineffective in traumatic acute injuries and in patients with fibrodysplasia ossificans progressiva (FOP. Therefore, the goal of this study is to profile the cytokines associated with HO using a different non-invasive source of biomarkers.MethodsSerum and saliva were collected from a model of trauma-induced HO (tHO with hind limb Achilles’ tenotomy and dorsal burn injury at indicated time points (pre-injury, 48 h, 1 week, and 3 weeks post-injury and a genetic non-trauma HO model (Nfatc1-Cre/caAcvr1fl/wt. Samples were analyzed for 27 cytokines using the Bio-Plex assay. Histologic evaluation was performed in Nfatc1-Cre/caAcvr1fl/wt mice and at 48 h and 1 week post-injury in burn tenotomy mice. The mRNA expression levels of these cytokines at the tenotomy site were also quantified with quantitative real-time PCR. Pearson correlation coefficient was assessed between saliva and serum.ResultsLevels of TNF-α and IL-1β peaked at 48 h and 1 week post-injury in the burn/tenotomy cohort, and these values were significantly higher when compared with both uninjured (p < 0.01, p < 0.03 and burn-only mice (p < 0.01, p < 0.01. Immunofluorescence staining confirmed enhanced expression of IL-1β, TNF-α, and MCP-1 at the tenotomy site 48 h after injury. Monocyte chemoattractant protein-1 (MCP-1 and VEGF was detected in saliva showing elevated levels at 1 week post-injury in our tHO model when compared with both uninjured (p < 0.001, p < 0.01 and burn-only mice (p < 0.005, p < 0.01. The Pearson correlation between serum MCP-1 and salivary MCP-1 was statistically significant (r = 0

    Carvalho, Paulo Cesar Gasse de

    1999-12-01

    The main purpose of this work is to develop an intelligent system to management and control, that allows to periodically evaluate the operational performance of a petroleum field producing with the wells equipped with PCP - Progressing Cavity Pump. The work was developed in two main stages. Initially, it was accomplished a literature search about PCP, in order to identify its fundamental parameters that provide a better operation of the system. Afterwards, based on the experience obtained during the last years with the accompaniment of petroleum fields in Bahia, it is proposed a control system for management of the petroleum field operations, centered to PCP. This system uses techniques of artificial intelligence, as fuzzy sets, to obtain better interpolations. It is desired that the results presented in this Master's thesis can be useful to managers, engineers, supervisors and operators to obtain a continuous and optimized performance of this artificial lift method, at petroleum production.

    Full Text Available São relatados 3 casos de pacientes femininos com atrofia dos músculos oculares extrínsecos, sendo 2 de início provável aos 25 anos e 1 aos 56 anos. No que se referem às intercorrencias não miogênicas, no caso 1 havia otoscle-rose, comum na família e incapacidade para engravidar. A menarca ocorreu aos 19 anos e a menopausa aos 40, o que igualmente ocorreu com o caso 2, este o único a mostrar alterações eletrocardiográficas. No caso 3 havia sinal de Romberg e hiporreflexia profunda, sendo comum a incidência de catarata congênita. Com relação à patologia muscular, apesar das queixas serem praticamente restritas aos músculos extrínsecos oculares, procedemos à biópsia de outros músculos, além dos oculares, evidenciando-se em todos acometimento do tipo miogênico, o mesmo ocorrendo na EMG. Acreditamos tratar-se de processo miogênico difuso, em que pese a dominância das manifestações oculares.

  18. L'imposizione progressiva nei paesi sottosviluppati. (Progressive taxation in underdeveloped countries

    C. COSCIANI

    2014-07-01

    Full Text Available The arguments for progressive taxation in the nineteenth century were strongly countered by reference to their harmful effects on the incentives to produce, save and invest. This position is still fairly widespread in discussions on what makes a sound fiscal policy for the underdeveloped countries today. The present article argues that progressive taxation corrects the maldistribution of national income, producing additional positive effects in a depressed economy in the process of development, especially as regards investment and the balance of payments. The considerations set out by the author suggest that in underdeveloped countries, progressive taxation must therefore not be regarded only from the point of view of national finance, but from that of the redistribution of income.JEL: E24, E62, H21, O15, F32

    2008-01-01

    Full Text Available An 8-year-old boy, diagnosed as cervical dystonia, was referred to our tertiary center. After a trivial trauma he had developed painful lumps in the axial region, which was followed by restricted movements of neck, shoulder, and abdominal muscles over 4 months. He had kyphoscoliosis, torticollis, rigid abdomen, and multiple muscle contractures. He also had short great toes. A detailed skeletal survey showed calcification in the soft tissues surrounding the shoulder anterior chest wall, thorax, and paraspinal muscles; there was also beaking of vertebrae, which was confirmed by CT thorax. This report showcases the diagnostic challenge posed by myositis ossificans progressiva, which can rarely cause rapidly progressing muscle contractures. A brief review of literature is also presented.

    The hands of 55 patients suffering from progressive sclerodermia were examined by liquid crystal thermography. The findings were compared with those of X-ray diagnosis and with clinical results. In 20 patients also capillary microscopy was applied. All patients revealed hypothermias in the fingers, independent from X-ray results, duration of the disease and Raynaud's phenomenon. Hypothermia could involve all fingers and was localized proximally or distally. In most of the patients also hyperthermias, not to be cooled, were found. They were diarthrodial and vasal, respectively

    Objective: To describe the high-resolution computed tomography findings in the lung of patients with systemic sclerosis, independently of the respiratory symptoms. Materials and methods: Seventy-three high-resolution computed tomography scans of 44 patients with clinical diagnosis of systemic sclerosis were reviewed and defined by the consensus of two radiologists. Results: Abnormalities were seen in 91.8% (n = 67) of the scans. The most frequent findings were reticular pattern (90.4%), ground-glass opacities (63%), traction bronchiectasis and bronchiolectasis (56.2%), esophageal dilatation (46.6%), honeycombing pattern (28.8%) and signs of pulmonary hypertension (15.6%). In most cases the lesions were bilateral (89%) and symmetrical (58.5%). The lesions were predominantly located in the basal (91.2%) and peripheral (92.2%) regions. Conclusion: In the majority of the patients, progressive systemic sclerosis can cause pulmonary fibrosis mainly characterized by reticular pattern with basal and peripheral distribution on high-resolution computed tomography.

  4. Heterotopic ossification revisited.

    Mavrogenis, Andreas F; Soucacos, Panayotis N; Papagelopoulos, Panayiotis J

    2011-03-11

    Heterotopic ossification is the abnormal formation of mature lamellar bone within extraskeletal soft tissues where bone does not exist. Heterotopic ossification has been classified into posttraumatic, nontraumatic or neurogenic, and myositis ossificans progressiva or fibrodysplasia ossificans progressive. The pathophysiology is unknown. Anatomically, heterotopic ossification occurs outside the joint capsule without disrupting it. The new bone can be contiguous with the skeleton but generally does not involve the periosteum. Three-phase technetium-99m (99mTc) methylene diphosphonate bone scan is the most sensitive imaging modality for early detection and assessing the maturity of heterotopic ossification. Nonsurgical treatment with indomethacin and radiation therapy is appropriate for prophylaxis or early treatment of heterotopic ossification. Although bisphosphonates are effective prophylaxis if initiated shortly after the trauma, mineralization of the bone matrix resumes after drug discontinuation. During the acute inflammatory stage, the patient should rest the involved joint in a functional position; once acute inflammatory signs subside, passive range of motion exercises and continued mobilization are indicated. Surgical indications for excision of heterotopic ossification include improvement of function, standing posture, sitting or ambulation, independent dressing, feeding and hygiene, and repeated pressure sores from underlying bone mass. The optimal timing of surgery has been suggested to be a delay of 12 to 18 months until radiographic evidence of heterotopic ossification maturation and maximal recovery after neurological injury. The ideal candidate for surgical treatment before 18 months should have no joint pain or swelling, a normal alkaline phosphatase level, and 3-phase bone scan indicating mature heterotopic ossification.

  5. Using Human Induced Pluripotent Stem Cells to Model Skeletal Diseases.

    Barruet, Emilie; Hsiao, Edward C

    2016-01-01

    Musculoskeletal disorders affecting the bones and joints are major health problems among children and adults. Major challenges such as the genetic origins or poor diagnostics of severe skeletal disease hinder our understanding of human skeletal diseases. The recent advent of human induced pluripotent stem cells (human iPS cells) provides an unparalleled opportunity to create human-specific models of human skeletal diseases. iPS cells have the ability to self-renew, allowing us to obtain large amounts of starting material, and have the potential to differentiate into any cell types in the body. In addition, they can carry one or more mutations responsible for the disease of interest or be genetically corrected to create isogenic controls. Our work has focused on modeling rare musculoskeletal disorders including fibrodysplasia ossificans progressive (FOP), a congenital disease of increased heterotopic ossification. In this review, we will discuss our experiences and protocols differentiating human iPS cells toward the osteogenic lineage and their application to model skeletal diseases. A number of critical challenges and exciting new approaches are also discussed, which will allow the skeletal biology field to harness the potential of human iPS cells as a critical model system for understanding diseases of abnormal skeletal formation and bone regeneration.

  6. Postoperative Bowel Perforation due to Heterotopic Ossification (Myositis Ossificans Traumatica: A Case Report and Review of the Literature

    2011-01-01

    Full Text Available Heterotopic ossification (HO is the ectopic development of normal bone within soft tissue that can occur after traumatic injury. It is uncommon and may be missed or misdiagnosed, which can lead to complications. We report the case of an 84-year-old male with a previous history of a laparotomy who underwent resection of an intra-abdominal tumor through a midline incision. On postoperative day six, the patient was taken to the operating room, as succus was draining from the incision. Upon re-exploration, sharp bone-like material was found in the wound directly adjacent to an enterotomy. Pathology confirmed mature lamellar bone and the diagnosis of HO. This is the first report of postoperative intestinal perforation secondary to HO in a midline wound. We report this case to encourage accurate reporting of HO and its morbidity and complications for the benefit of appropriate surgical planning and epidemiologic tracking of outcomes.

  7. Integrating Gene Correction in the Reprogramming and Transdifferentiation Processes: A One-Step Strategy to Overcome Stem Cell-Based Gene Therapy Limitations

    Seo-Young Lee

    2016-01-01

    Full Text Available The recent advent of induced pluripotent stem cells (iPSCs and gene therapy tools has raised the possibility of autologous cell therapy for rare genetic diseases. However, cellular reprogramming is inefficient in certain diseases such as ataxia telangiectasia, Fanconi anemia, LIG4 syndrome, and fibrodysplasia ossificans progressiva syndrome, owing to interference of the disease-related genes. To overcome these therapeutic limitations, it is necessary to fundamentally correct the abnormal gene during or prior to the reprogramming process. In addition, as genetic etiology of Parkinson’s disease, it has been well known that induced neural stem cells (iNSCs were progressively depleted by LRRK2 gene mutation, LRRK2 (G2019S. Thus, to maintain the induced NSCs directly derived from PD patient cells harboring LRRK2 (G2019S, it would be ideal to simultaneously treat the LRRK2 (G2019S fibroblast during the process of TD. Therefore, simultaneous reprogramming (or TD and gene therapy would provide the solution for therapeutic limitation caused by vulnerability of reprogramming or TD, in addition to being suitable for general application to the generation of autologous cell-therapy products for patients with genetic defects, thereby obviating the need for the arduous processes currently required.

  8. Temporomandibular joint ankylosis as part of the clinical spectrum of Carey-Fineman-Ziter syndrome?

    Pasetti, Martina; Mazzoleni, Fabio; Novelli, Giorgio; Iascone, Maria; Bozzetti, Alberto; Selicorni, Angelo

    2016-08-01

    The Carey-Finema-Ziter syndrome (CFZS, MIM 254940) is an apparently autosomal recessively inherited disorder consisting of the combination of non-progressive congenital myopathy with Moebius and Pierre Robin sequence, facial anomalies and growth delay. Mental development has been described as normal or delayed. Temporomandibular joint (TMJ) ankylosis is the immobility of the joint caused by ankylotic fusion of the mandible to the cranial base or zygoma. It is a serious and disabling condition that may cause problems in mastication, digestion, speech, appearance, and oral hygiene. Most often is a true ankylosis of the TMJ but other pathological mechanisms are described (i.e., the fusion of the coronoid process to temporal bone or with the zygoma, or a variety of soft tissues disorders like Fibrodysplasia Ossificans Progressiva). Here we report a 2-year-old girl fitting with a clinical diagnosis of CFZS associated with a limited mouth opening in which temporomandibular joint ankylosis was suspected. Because it has been postulated that many clinical features in CFZS may only be secondary effects of brainstem anomalies and muscle weakness during development, the limited opening of the mouth observed in our patient could represent a rare clinical feature of CFZS itself. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    Full Text Available Na introdução deste artigo, o autor parte de uma preocupação com o debate atual em torno do processo de tentativa de inovação política setorial que vem sendo designado entre nós pela expressão "Reforma Sanitária". Chama a atenção para os diferentes sentidos em que, a seu ver, esta expressão tem sido utilizada no Brasil E se dispõe a deter-se, particularmente, em um destes sentidos: o que se aproxima da formulação italiana de mesmo nome (a "Riforma Sanitária". Esta discussão o leva, no corpo do artigo propriamente dito, a tratar, centralmente, da relação entre as características assumidas pela ordenação política liberal contemporânea e a estratégia gramsci-togliattiana de transição no socialismo, no que tange ao tema das chamadas "Políticas Públicas" e, mais particularmente, das "Políticas Sociais". O artigo termina com um esboço inicial de um projeto de investigação comparativa nesta área.In the introduction, the author discusses the current debate on the "Reforma Sanitária"; a proposal to innovate health policy. The author draws attention to the different meanings that can be attributed, in his opinion, to the use of this term in Brazil. He focusses particularly on the meaning closer to that of the Italian proposal of the same name ("Riforma Sanitaria". The discussion leads the author to question the relationship between the characteristics of the contemporary political liberal organization and the Gramsci-Togliattian strategy of the transition in socialism, within the field of "Public Policies" and more specifically ''Social Policies". The article ends with a preliminary outline a comparative investigation in this field.

    One of the most important equipment in the progressing cavity pump (PCP) is the subsurface pump, which comprises a rotor and a stator covered internally by an elastomer. This is responsible for sealing the pump and, consequently, for elevating the fluids. In fact, this polymer is used because of the ability to generate pressure in the pump by the seals formed between the cavities. In order to guarantee that the elastomer will have a good performance in the PCP system certain requirements need to be checked, such as: stress, elongation, hardness, resilience, permeability and adhesion. The fluids and solids handled by the PCP system, allied to high temperatures can cause premature wear in the elastomers. The most common reactions which are also observed in most of the wells are swelling, shrinkage, softening, hardening and explosive decompression. In this sense, the aim of this work is to study some elastomers which were chosen based on compatibility tests conducted by a major oil company. The problems that occurred in the wells will be analyzed in order to verify whether the choice of the elastomer had some influence on system failure. For this purpose, the intervention reports, efficiency tests and failure analysis reports will be used. At the end of this work, it was possible to diagnose the causes, consequences and solutions to inherent problems at various oil wells in a field that is in an advanced stage of recovery. Finally, it was concluded that simple changes in the process of compatibility analysis would help to increase the reliability level of the tests, especially the problems observed during the PCP operation in hostile environments.

These findings are consistent with the observation that BMP receptor hyperactivation correlates with bone abnormalities and pain sensitization in fibrodysplasia ossificans progressiva (Kitterman et al., 2012). Because nociceptive sensitization is associated with chronic pain, these findings indicate that human BMP pathway components may represent targets for novel pain-relieving drugs.

  18. Principles for interactions with biopharmaceutical companies: the development of guidelines for patient advocacy organizations in the field of rare diseases.

    Stein, Susan; Bogard, Elizabeth; Boice, Nicole; Fernandez, Vivian; Field, Tessa; Gilstrap, Alan; Kahn, Susan R; Larkindale, Jane; Mathieson, Toni

    2018-01-22

    Rare diseases are a global public health concern, affecting an estimated 350 million individuals. Only 5% of approximately 7000 known rare diseases have a treatment, and only about half have a patient advocacy organization. Biopharmaceutical companies face complex challenges in developing treatments for rare diseases. Patient advocacy organizations may play a major role by positively influencing research and development, clinical trials, and regulations. Thus, collaboration among patient advocacy organizations and industry is essential to bring new therapeutics to patients. We identified an unmet need for guidelines on day-to-day decision-making by rare disease patient advocacy organizations when working with biopharmaceutical partners. We convened an Independent Expert Panel experienced in collaborations between patient advocacy organizations and biopharmaceutical companies (April 2017) to develop consensus guidelines for these relationships. The guidelines were based on an original version by the International Fibrodysplasia Ossificans Progressiva Association (IFOPA). The Expert Panel reviewed and broadened these to be applicable to all patient advocacy organizations. Comments on the draft Guidelines were provided first by Panel participants and subsequently by six independent experts from patient advocacy organizations and industry. The Panel comprised four experts from the rare disease community who lead patient advocacy organizations; three leaders who perform advocacy functions within biopharmaceutical companies; and two facilitators, both having leadership experience in rare diseases and industry. The finalized Guidelines consist of four main sections: Identification and Engagement With Companies, Patient Engagement and Patient Privacy, Financial Contributions, and Clinical Trial Communication and Support. The Guidelines address the daily considerations, choices, and consequences of patient advocacy organizations as they engage with biopharmaceutical

  1. The impact of front-of-pack nutrition labels on consumer product evaluation and choice: an experimental study.

    Hamlin, Robert P; McNeill, Lisa S; Moore, Vanessa

    2015-08-01

    The present research was an experimental test that aimed to quantify the impact of two dominant front-of-pack (FOP) nutritional label formats on consumer evaluations of food products that carried them. The two FOP label types tested were the traffic light label and the Percentage Daily Intake. A 4×5 partially replicated Latin square design was used that allowed the impact of the FOP labels to be isolated from the effects of the product and the consumers who were performing the evaluations. The experiment was conducted on campus at the University of Otago, New Zealand. The participants were 250 university students selected at random who met qualifying criteria of independent living and regular purchase of the products used in the research. They were not aware of the purpose of the research. The presence of FOP labels led to significant and positive changes in consumer purchase intentions towards the products that carried them. These changes were not affected by the nature of FOP labels used, their size or the product nutritional status (good/bad) that they were reporting. The result is consistent with the participants paying attention to the FOP label and then using it as an adimensional cue indicating product desirability. As such, it represents a complete functional failure of both of these FOP label types in this specific instance. This result supports calls for further research on the performance of these FOP labels before any move to compulsory deployment is made.

  3. Does depression decrease the moderating effect of self-efficacy in the relationship between illness perception and fear of progression in breast cancer?

    Shim, Eun-Jung; Lee, Jong Won; Min, Yul Ha

    2018-02-01

    Fear of progression (FOP) is a prevalent concern among breast cancer patients that affect their adjustment to disease. This study examined whether self-efficacy moderates the effect of illness perception (IP) on FOP and whether the moderating effect of self-efficacy depends on the level of depressive symptoms. A cross-sectional survey including brief illness perception questionnaire (BIPQ), FOP short form, general self-efficacy scale, and the center for epidemiologic studies depression scale were administered to 245 patients with breast cancer in Korea. Self-efficacy moderated the negative impact of the patients' perception of chronic timeline and a greater emotional impact of the illness on FOP. However, the moderating effect of self-efficacy of the BIPQ timeline and emotions on FOP depended on level of depressive symptoms. The findings underscore the importance of considering the IP as determinants of FOP, as well as of self-efficacy and depression as the moderating factors in the relationship between IP and FOP, suggesting the need to enhance self-efficacy and depressive symptoms in order to compensate the negative impact of IP on FOP in breast cancer patients.

    Objective: To study the CT characteristics of solitary focal organizing pneumonia (FOP). Materials and methods: Chest CT of consecutive 45 patients (34 males and 11 females, median age: 56 years) with confirmed FOP were analyzed. The CT features between large FOP (>3 cm, n = 27) and small FOP (≤3 cm, n = 18) were compared. Results: FOP lesions predominately located in peripheral lungs (86.7%), with the right lower lobe being most common lobe (44.4%). No lesion mainly located in the inner 1/3 of lungs. All large lesions were polygon in shape and had an irregular margin, while small lesions were more likely to be round or oval with an irregular or smooth border. Air bronchogram or small bubble-like lucency was present in majority of the lesions. 42.2% of lesions had incompact internal structure with inhomogeneous density besides air component. Most lesions were associated with a contraction or convergence of surrounding vessels; while no pulmonary vessel was interrupted abruptly by a small FOP lesion. Majority of large lesions had broad contact with the pleura, while only one patient had mild pleural effusion. Mild mediastinal lymph nodes enlargement was present in about 1/5 of the patients. Conclusion: Compared with the known CT features of lung cancer, our results suggest differential diagnosis can often be made for large FOP, while small FOP may resemble lung cancer.

  5. Attitude and Behavior Factors Associated with Front-of-Package Label Use with Label Users Making Accurate Product Nutrition Assessments.

    Roseman, Mary G; Joung, Hyun-Woo; Littlejohn, Emily I

    2018-05-01

    Front-of-package (FOP) labels are increasing in popularity on retail products. Reductive FOP labels provide nutrient-specific information, whereas evaluative FOP labels summarize nutrient information through icons. Better understanding of consumer behavior regarding FOP labels is beneficial to increasing consumer use of nutrition labeling when making grocery purchasing decisions. We aimed to determine FOP label format effectiveness in aiding consumers at assessing nutrient density of food products. In addition, we sought to determine relationships between FOP label use and attitude toward healthy eating, diet self-assessment, self-reported health and nutrition knowledge, and label and shopping behaviors. A between-subjects experimental design was employed. Participants were randomly assigned to one of four label conditions: Facts Up Front, Facts Up Front Extended, a binary symbol, and no-label control. One hundred sixty-one US primary grocery shoppers, aged 18 to 69 years. Participants were randomly invited to the online study. Participants in one of four label condition groups viewed three product categories (cereal, dairy, and snacks) with corresponding questions. Adults' nutrition assessment of food products based on different FOP label formats, along with label use and attitude toward healthy eating, diet self-assessment, self-reported health and nutrition knowledge, and label and shopping behaviors. Data analyses included descriptive statistics, χ 2 tests, and logistical regression. Significant outcomes were set to α=.05. Participants selected the more nutrient-dense product in the snack food category when it contained an FOP label. Subjective health and nutrition knowledge and frequency of selecting food for healthful reasons were associated with FOP label use (P<0.01 and P<0.05, respectively). Both Facts Up Front (reductive) and binary (evaluative) FOP labels appear effective for nutrition assessment of snack products compared with no label. Specific

  6. To See or Not to See: Do Front of Pack Nutrition Labels Affect Attention to Overall Nutrition Information?

    Laura Bix

    Full Text Available Front of pack (FOP nutrition labels are concise labels located on the front of food packages that provide truncated nutrition information. These labels are rapidly gaining prominence worldwide, presumably because they attract attention and their simplified formats enable rapid comparisons of nutritional value.Eye tracking was conducted as US consumers interacted with actual packages with and without FOP labels to (1 assess if the presence of an FOP label increases attention to nutrition information when viewers are not specifically tasked with nutrition-related goals; and (2 study the effect of FOP presence on consumer use of more comprehensive, traditional nutrition information presented in the Nutritional Facts Panel (NFP, a mandatory label for most packaged foods in the US.Our results indicate that colored FOP labels enhanced the probability that any nutrition information was attended, and resulted in faster detection and longer viewing of nutrition information. However, for cereal packages, these benefits were at the expense of attention to the more comprehensive NFP. Our results are consistent with a potential short cut effect of FOP labels, such that if an FOP was present, participants spent less time attending the more comprehensive NFP. For crackers, FOP labels increased time spent attending to nutrition information, but we found no evidence that their presence reduced the time spent on the nutrition information in the NFP.The finding that FOP labels increased attention to overall nutrition information by people who did not have an explicit nutritional goal suggests that these labels may have an advantage in conveying nutrition information to a wide segment of the population. However, for some food types this benefit may come with a short-cut effect; that is, decreased attention to more comprehensive nutrition information. These results have implications for policy and warrant further research into the mechanisms by which FOP labels

    Clever, Katharina; Schepper, Florian; Küpper, Luise; Christiansen, Holger; Martini, Julia

    2018-04-01

    Fear of Progression (FoP) is a commonly reported psychological strain in parents of children with cancer. This expert survey investigates how professionals in pediatric oncology estimate the burden and consequences of FoP in parents and how they assess and treat parental FoP. N=77 professionals in pediatric oncology (members and associates of the Psychosocial Association in Paediatric Oncology and Haematology, PSAPOH) were examined in an online survey with a self-developed questionnaire. Data were analyzed via descriptive statistics and qualitative content analysis. Three of four experts in clinical practice were (very) often confronted with parental FoP which was associated with more negative (e. g., psychosomatic reactions, reduced family functioning) than positive (e. g., active illness processing) consequences. N=40 experts indicated that they mainly assess parents' anxiety via clinical judgment (72.5%) and/or according to ICD-10/DSM-5 diagnostic criteria (37.5%), whereas standardized methods such as psycho-oncological questionnaires (12.5%) were applied less often. Only n=6 experts named a specific diagnostic approach to assess parental FoP. The most common treatment approaches for FoP were supportive counseling (74.0%), psychotherapy (59.7%) and/or relaxation techniques (55.8%). Parental FoP is frequently perceived by experts in clinical practice. A standardized diagnostic procedure would increase comparability of diagnostic judgments and harmonize treatment indications. © Georg Thieme Verlag KG Stuttgart · New York.

  10. The role of nutrition labels and advertising claims in altering consumers' evaluation and choice.

    Bialkova, Svetlana; Sasse, Lena; Fenko, Anna

    2016-01-01

    Despite policy efforts, consumers' well-informed healthful choice is a challenge. Due to increasing number of benefit claims advertising taste or health front of pack (FOP), consumers face the dilemma to trade taste for health. To understand the mechanisms underlying food evaluation, this study investigates the health-pleasure trade-off and its effect on consumers' choice. 240 EU consumers took part in a taste experiment, after being presented with the product FOP. Half of the products carried a nutrition label FOP, respectively, reduced fat for potato chips, reduced sugar for cereal bars. Further, one third of the products carried health benefit claim, one third taste benefit claim, and one third no additional claim FOP. Attention to information and its effect on experienced taste, health perception and the buying intention were measured. The results show that the message displayed FOP altered consumers evaluation and choice. The effectiveness of the FOP message further depended on consumers' health motivation and the healthfulness perception of carrier products. The outcomes are summarized in a framework of health-pleasure trade-off. Current findings call for the establishment of standards to avoid the use of misleading information FOP.

    2015-10-01

    1) To assess whether Front-of-Pack (FOP) nutrition labels garner attention more readily than more complete, mandated nutrition information (the Nutrition Facts Panel (NFP), required in the US), and 2) To determine whether label design characteristics, specifically, color coding and/or coding with facial icons, increase attention to the FOP label. In two experiments, we tracked the allocation of attention while participants (n=125) viewed novel and commercial packages with varied FOP designs using a change detection methodology. We found empirical evidence that FOP labels are attended more often, and earlier, than the currently mandated NFP, and that this benefit is due both to its placement on the front of the package and to the design characteristics of the FOP. Specifically, the use of color in FOPs increased attention to the label, but there was no evidence that coding information via facial icons impacted attention. Our work supports a growing body of evidence supporting the use of FOP labels to attract attention to nutritional information. Findings may be relevant to inform policy decisions on labeling standards.

    Full Text Available INTRODUCTION: Administration of the NO inhibitor Nwð-nitro-L-arginine methyl ester (NAME and a high-salt diet (HS promotes severe albuminuria and renal injury, which regresses upon discontinuation of treatments. OBJECTIVE: We investigated whether these changes reappear after reinstitution of HS, and whether they are prevented by treatment with the antilymphocyte agent mycophenolate mofetil (MMF or the AT-1 receptor blocker losartan (L. Adult male Munich-Wistar rats received NAME and HS. A control Group (C received only HS. After 20 days, rats receiving HS and NAME exhibited severe hypertension and albuminuria. After a 30-day recovery period, hypertension was attenuated and albuminuria had virtually disappeared. MATERIAL AND METHODS: Rats were then distributed among the following groups: HS, receiving HS; NS, receiving a normal salt (NS diet; HS-MMF, receiving HS and MMF; HS-LOS, receiving HS and L; HS-HDZ, receiving HS and hydralazine (HDZ. Sixty days later, NS rats showed only slight albuminuria and renal damage or inflammation. In contrast, HS rats developed severe hypertension, marked glomerulosclerosis with interstitial expansion and renal infiltration by macrophages and angiotensin II-positive cells. The group treated with losartan had lowered blood pressure and a lack of albuminuria or renal injury. MMF provided similar protection without altering blood pressure, suggesting a nonhemodynamic effect, a hypothesis reinforced by the finding that HDZ lowered blood pressure without preventing renal injury. RESULTS: These results indicate that treatment with HS and NAME predisposes to the development of hypertension and renal injury upon salt overload, characterizing a new model of chronic nephropathy. CONCLUSION: The response to MMF or L, but not HDZ, suggests a key role for inflammatory rather than hemodynamic factors.INTRODUÇÃO: A administração de Nômega-nitro-L-arginina metiléster (NAME, um inibidor da produção de NO, com dieta rica em sal (HS promove albuminúria e dano renal graves, reversíveis ao interromperem-se os tratamentos. OBJETIVO: Investigamos se tais alterações recrudescem ao reinstituir-se a HS e se são prevenidas pelo micofenolato mofetil (MMF, um agente antilinfócito, ou losartan, um bloqueador do receptor AT-1. MATERIAL E MÉTODOS: Ratos Münich-Wistar machos adultos receberam NAME e HS. Um grupo controle (C recebeu apenas HS. Após 20 dias, os ratos que receberam HS e NAME exibiam hipertensão e albuminúria graves. Após recuperação de 30 dias, a hipertensão atenuou-se e a albuminúria praticamente desapareceu. Formaram-se então os grupos: HS, recebendo HS; NS, recebendo dieta normal em sal (NS; HS-MMF, recebendo HS e MMF; HS-LOS, recebendo HS e losartan; HS-HDZ, recebendo HS e hidralazina. Após sessenta dias os ratos NS tinham albuminúria e dano/inflamação renal apenas discretos. Já os ratos HS desenvolveram hipertensão e glomerulosclerose acentuadas, expansão intersticial e infiltração renal por macrófagos e células positivas para angiotensina II. Losartan baixou a pressão arterial e preveniu albuminúria e lesão renal. MMF proporcionou proteção semelhante sem alteração pressórica, sugerindo a ação de mecanismos não hemodinâmicos, hipótese reforçada pelo achado de que a HDZ baixou a pressão arterial sem prevenir a nefropatia. RESULTADOS: Esses resultados indicam que o tratamento com HS e NAME predispõe ao desenvolvimento de hipertensão e lesão renal induzidos por excesso de sal, caracterizando um novo modelo de nefropatia crônica. CONCLUSÃO: A resposta ao MMF ou losartan, mas não à hidralazina, sugere o predomínio de fatores inflamatórios.

    2015-05-01

    Recurrent headache sufferers are often fearful of pain, which disrupts thought processes, interferes with daily activities, and may maintain headache-related disability through avoidance and associated negative reinforcement. The aim of this cross-sectional study was to (1) examine differences in fear of pain (FOP) between headache sufferers and non-headache controls; (2) examine differences in FOP across primary headache diagnostic groups; (3) assess the extent to which FOP predicts headache variables (eg., severity, frequency, disability); and (4) determine whether FOP mediates the relationship between pain severity and headache-related disability. The sample consisted of 908 young adults (M age = 19.5 years; 64.9% female). Of those, 237 (26.1%) met the diagnostic criteria for episodic tension-type headache (TTH), 232 (25.6%) for episodic migraine (167 [18.4%] without aura and 65 [7.2%] with aura), 38 (4.2%) for chronic migraine, and 19 (2.1%) for chronic TTH; 382 (42.1%) served as non-headache controls. FOP differed among groups, with headache sufferers reporting greater FOP than those without headache; migraineurs typically endorsed greater FOP than those with TTH. Among those with headache, FOP significantly predicted headache severity (R(2)  = 6.1%) and frequency (R(2)  = 4.5%), and accounted for more variance in disability (R(2)  = 17.5%) than gender, anxiety, and depression combined (13.8%). Pain severity and disability were strongly associated (r = 0.61, P headache and plays a significant role in primary headache, particularly in headache-related disability. Findings build upon and extend those from previous chronic pain studies and highlight the need for longitudinal and experimental studies to further explore this construct in headache. © 2015 American Headache Society.

  17. Does front-of-pack nutrition information improve consumer ability to make healthful choices? Performance of warnings and the traffic light system in a simulated shopping experiment.

    The inclusion of more attention-grabbing and easily interpretable front-of-pack (FOP) nutrition information is one of the public policies that can be implemented to empower consumers to identify unhealthful food products and to make more informed food choices. The aim of the present work was to evaluate the influence of two FOP nutrition labelling schemes - the traffic light labelling and the warning scheme - on consumer food purchases when facing a health goal. The study was conducted with 1182 people from Montevideo (Uruguay), recruited using a Facebook advertisement. Participants were randomly allocated to one of three between-subjects experimental conditions: (i) a control condition with no FOP nutrition information, (ii) FOP nutrition information using a modified version of the traffic light system including information about calorie, saturated fat, sugars and sodium content per portion, and (iii) FOP nutrition information using the Chilean warning system including separate signs for high calorie, saturated fat, sugars and sodium content. Respondents were asked to imagine that they had to purchase food in order to prepare a healthy dinner for themselves and their family, using the website of an online grocery store. Results showed that FOP nutrition information effectively improved the average healthfulness of participants' choices compared to the control condition, both in terms of the average nutritional composition of the purchased products and expenditure in specific product categories. No relevant differences between the effect of the traffic light and the warning system were found. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Full Text Available Francisella tularensis is a Gram-negative facultative intracellular bacterium and the causative agent of the lethal disease tularemia. An outer membrane protein (FTT0918 of F. tularensis subsp. tularensis has been identified as a virulence factor. We generated a F. novicida (F. tularensis subsp. novicida FTN_0444 (homolog of FTT0918 fopC mutant to study the virulence-associated mechanism(s of FTT0918.The ΔfopC strain phenotype was characterized using immunological and biochemical assays. Attenuated virulence via the pulmonary route in wildtype C57BL/6 and BALB/c mice, as well as in knockout (KO mice, including MHC I, MHC II, and µmT (B cell deficient, but not in IFN-γ or IFN-γR KO mice was observed. Primary bone marrow derived macrophages (BMDM prepared from C57BL/6 mice treated with rIFN-γ exhibited greater inhibition of intracellular ΔfopC than wildtype U112 strain replication; whereas, IFN-γR KO macrophages showed no IFN-γ-dependent inhibition of ΔfopC replication. Moreover, phosphorylation of STAT1 was downregulated by the wildtype strain, but not the fopC mutant, in rIFN-γ treated macrophages. Addition of NG-monomethyl-L-arginine, an NOS inhibitor, led to an increase of ΔfopC replication to that seen in the BMDM unstimulated with rIFN-γ. Enzymatic screening of ΔfopC revealed aberrant acid phosphatase activity and localization. Furthermore, a greater abundance of different proteins in the culture supernatants of ΔfopC than that in the wildtype U112 strain was observed.F. novicida FopC protein facilitates evasion of IFN-γ-mediated immune defense(s by down-regulation of STAT1 phosphorylation and nitric oxide production, thereby promoting virulence. Additionally, the FopC protein also may play a role in maintaining outer membrane stability (integrity facilitating the activity and localization of acid phosphatases and other F. novicida cell components.

  20. Consumer perceptions of the Nutrition Facts table and front-of-pack nutrition rating systems.

    Emrich, Teri E; Qi, Ying; Mendoza, Julio E; Lou, Wendy; Cohen, Joanna E; L'abbé, Mary R

    2014-04-01

    Preferences for, and consumer friendliness of, front-of-pack (FOP) nutrition rating systems have not been studied in a Canadian population, and studies comparing systems that are accompanied by mandatory labelling, such as Canada's Nutrition Facts table (NFt), are lacking. The purpose of this study was to evaluate 4 FOP systems relative to the NFt with respect to consumer friendliness and their influence on perceptions of the healthiness and nutrient content of food. Canadian consumers (n = 3029) participating in an online survey were randomized to score the consumer friendliness of 1 of 5 FOP conditions with or without an NFt and to score the healthiness and nutrient content of 2 foods using the provided label(s). The mean differences in scores were evaluated with analysis of covariance (ANCOVA) controlling for age, gender, and education, with Tukey-Kramer adjustments for multiple comparisons. The NFt received the highest scores of consumer friendliness with respect to liking, helpfulness, credibility, and influence on purchase decisions (p consumers still supported the implementation of a single, standardized FOP system, with the nutrient-specific systems (a "Traffic Light" and a Nutrition Facts FOP system) being preferred and scored as more consumer friendly than the summary indicator systems. Without the NFt, consumer ratings of the healthiness and calorie and nutrient content differed by FOP system. With the NFt present, consumers rated the healthiness and calorie and nutrient content similarly, except for those who saw the Traffic Light; their ratings were influenced by the Traffic Light's colours. The introduction of a single, standard, nutrient-specific FOP system to supplement the mandatory NFt should be considered by Canadian policy makers.

  1. Nutrient profiling for front of pack labelling: how to align logical consumer choice with improvement of products?

    Roodenburg, Annet J C

    2017-08-01

    The primary goal of front of pack (FOP) labelling is to help consumers make healthier choices through communication. A secondary goal is to encourage producers to improve the nutritional composition of their products. Evidence has shown that (FOP) labelling can help consumers to make healthier food choices and has been an incentive for producers to improve product composition. As FOP labelling is seen as an important tool to improve food environments for public health purposes, the WHO supports initiatives of governments to implement an FOP labelling system. Based on the experiences of a wide range of countries over many years, possible success factors for such an FOP system have been defined, six of which are discussed in the present paper and used to evaluate the Dutch Choices Programme that was started in 2006. In the course of time a large number of producers joined the programme and the logo was recognised by more than 90 % of the consumers, but by 2016 the Dutch consumer organisation argued on the basis of their own research that a quarter of the consumers did not understand the colour coding of the logo and as a result the Dutch government decided to no longer support this logo and to introduce a nutrition app. The challenge that remains is to find a system that consumers understand well and that still encourages manufacturers of food to improve product composition. New technology-based data collecting initiatives might provide the right tools to develop such a system.

  2. Consumer perceptions of specific design characteristics for front-of-package nutrition labels.

    Acton, R B; Vanderlee, L; Roberto, C A; Hammond, D

    2018-04-01

    An increasing number of countries are developing front-of-package (FOP) labels; however, there is limited evidence examining the impact of specific design characteristics for these labels. The current study investigated consumer perceptions of several FOP label design characteristics, including potential differences among sociodemographic sub-groups. Two hundred and thirty-four participants aged 16 years or older completed nine label rating tasks on a laptop at a local shopping mall in Canada. The rating tasks asked participants to rate five primary design characteristics (border, background presence, background colour, 'caution' symbol and government attribution) on their noticeability, readability, believability and likelihood of changing their beverage choice. FOP labels with a border, solid background and contrasting colours increased noticeability. A solid background increased readability, while a contrasting background colour reduced it. Both a 'caution' symbol and a government attribution increased the believability of the labels and the perceived likelihood of influencing beverage choice. The effect of the design characteristics was generally similar across sociodemographic groups, with modest differences in five of the nine outcomes. Label design characteristics, such as the use of a border, colour and symbols can enhance the salience of FOP nutrition labels and may increase the likelihood that FOP labels are used by consumers.

  7. When zero is greater than one: consumer misinterpretations of nutrition labels.

    Graham, Dan J; Mohr, Gina S

    2014-12-01

    Front-of-package (FOP) nutrition labels are increasingly used by food manufacturers. A call to regulate the content and format of these labels resulted in recommendations by the Institute of Medicine (IOM) for standardized FOP labels that clearly communicate packaged foods' healthfulness. It is currently unclear how consumers would interpret and use these proposed labels. This research addresses psychological factors affecting the efficacy of FOP label use. It was hypothesized that IOM's proposed 0- to 3-point rating scale would produce the zero-comparison effect, leading to more favorable evaluations than are warranted for the least healthful products (i.e., those earning zero nutritional points). In two studies (Study 1, n = 68; Study 2, n = 101), participants evaluated products containing FOP labels on the basis of IOM recommendations. Primary outcomes were perceived product healthfulness and purchase intentions. Study 1 demonstrated that less-healthful products were rated by study participants to be equally healthful as more-healthful products. The relationship between FOP rating and purchase intentions was mediated by perceived healthfulness. Biases in product healthfulness ratings were exacerbated for consumers with higher (vs. lower) health concern. Study 2 demonstrated that by changing the rating scale from 0-3 to 1-4, consumers avoid the zero-comparison effect and accurately evaluate products' healthfulness. This research has implications for theory and policy in the domains of nutrition labeling and consumer health. Specifically, FOP labels can help consumers identify healthful options, but products receiving zero nutritional points may be misidentified as healthful; a simple label modification can prevent this confusion.

  8. Comparison of two front-of-package nutrition labeling schemes, and their explanation, on consumers' perception of product healthfulness and food choice.

    Lundeberg, Pamela J; Graham, Dan J; Mohr, Gina S

    2018-06-01

    Front-of-package (FOP) nutrition labels are increasingly used to present nutritional information to consumers. A variety of FOP nutrition schemes exist for presenting condensed nutrition information. The present study directly compared two symbolic FOP labeling systems - traffic light and star-based schemes - with specific regard to healthfulness perception and purchase intention for a variety of products. Additionally, this study investigated which method of message framing (gain, loss, gain + loss) would best enable individuals to effectively utilize the FOP labels. College students (n = 306) viewed food packages featuring either star or traffic light FOP labels and rated the healthfulness of each product and their likelihood of purchasing the product. Within each label type, participants were presented with differently-framed instructions regarding how to use the labels. Participants who viewed the star labels rated products with the lowest healthfulness as significantly less healthful and rated products with the highest healthfulness as significantly more healthful compared to participants who viewed those same products with traffic light labels. Purchase intention did not differ by label type. Additionally, including any type of framing (gain, loss, or gain + loss) assisted consumers in differentiating between foods with mid-range vs. low nutritional value. Star-based labels led more healthful foods to be seen as even more healthful and less healthful foods to be seen as even less healthful compared to the same foods with traffic light labels. Additionally, results indicate a benefit of including framing information for FOP nutrition label instructions; however, no individual frame led to significantly different behavior compared to the other frames. While ratings of product healthfulness were influenced by the framing and the label type, purchase intention was not impacted by either of these factors. Copyright © 2018 Elsevier Ltd. All rights

  9. Differentially Expressed Genes in Resistant and Susceptible Common Bean (Phaseolus vulgaris L. Genotypes in Response to Fusarium oxysporum f. sp. phaseoli.

    Renfeng Xue

    Full Text Available Fusarium wilt of common bean (Phaseolus vulgaris L., caused by Fusarium oxysporum Schlechtend.:Fr. f.sp. phaseoli (Fop, is one of the most important diseases of common beans worldwide. Few natural sources of resistance to Fop exist and provide only moderate or partial levels of protection. Despite the economic importance of the disease across multiple crops, only a few of Fop induced genes have been analyzed in legumes. Therefore, our goal was to identify transcriptionally regulated genes during an incompatible interaction between common bean and the Fop pathogen using the cDNA amplified fragment length polymorphism (cDNA-AFLP technique. We generated a total of 8,730 transcript-derived fragments (TDFs with 768 primer pairs based on the comparison of a moderately resistant and a susceptible genotype. In total, 423 TDFs (4.9% displayed altered expression patterns after inoculation with Fop inoculum. We obtained full amplicon sequences for 122 selected TDFs, of which 98 were identified as annotated known genes in different functional categories based on their putative functions, 10 were predicted but non-annotated genes and 14 were not homologous to any known genes. The 98 TDFs encoding genes of known putative function were classified as related to metabolism (22, signal transduction (21, protein synthesis and processing (20, development and cytoskeletal organization (12, transport of proteins (7, gene expression and RNA metabolism (4, redox reactions (4, defense and stress responses (3, energy metabolism (3, and hormone responses (2. Based on the analyses of homology, 19 TDFs from different functional categories were chosen for expression analysis using quantitative RT-PCR. The genes found to be important here were implicated at various steps of pathogen infection and will allow a better understanding of the mechanisms of defense and resistance to Fop and similar pathogens. The differential response genes discovered here could also be used as

    This document is the Groundwater Level Monitoring Sampling and Analysis Plan (SAP) for Waste Area Grouping (WAG) 6 at Oak Ridge National Laboratory (ORNL). Note that this document is referred to as a SAP even though no sampling and analysis will be conducted. The term SAP is used for consistency. The procedures described herein are part of the Environmental Monitoring Plan (EMP) for WAG 6, which also includes monitoring tasks for seeps and springs, groundwater quality, surface water, and meteorological parameters. Separate SAPs are being issued concurrently to describe each of these monitoring programs. This SAP has been written for the use of the field personnel responsible for implementation of the EMP, with the intent that the field personnel will be able to take these documents to the field and quickly find the appropriate steps required to complete a specific task. In many cases, Field Operations Procedures (FOPs) will define the steps required for an activity. The FOPs for the EMP are referenced and briefly described in the relevant sections of the SAPs, and are contained within the FOP Manual. Both these documents (the SAP and the FOP Manual) will be available to personnel in the field.

    Research on the relative influence of package features on children's perception of food products is still necessary to aid policy design and development. The aim of the present work was to evaluate the relative influence of two front-of-pack (FOP) nutrition labelling schemes, the traffic light system and Chilean warning system, and label design on children's choice of two popular snack foods in Uruguay, wafer cookies and orange juice. A total of 442 children in grades 4 to 6 from 12 primary schools in Montevideo (Uruguay) participated in the study. They were asked to complete a choice-conjoint task with wafer cookies and orange juice labels, varying in label design and the inclusion of FOP nutrition information. Half of the children completed the task with labels featuring the traffic-light system (n = 217) and the other half with labels featuring the Chilean warning system (n = 225). Children's choices of wafer cookies and juice labels was significantly influenced by both label design and FOP nutritional labels. The relative impact of FOP nutritional labelling on children's choices was higher for the warning system compared to the traffic-light system. Results from the present work stress the need to regulate the design of packages and the inclusion of nutrient claims, and provide preliminary evidence of the potential of warnings to discourage children's choice of unhealthful products.

  15. Mandatory labels, taxes and market forces: An empirical evaluation of fat policies.

    Allais, Olivier; Etilé, Fabrice; Lecocq, Sébastien

    2015-09-01

    The public-health community views mandatory Front-of-Pack (FOP) nutrition labels and nutritional taxes as promising tools to control the growth of food-related chronic diseases. This paper uses household scanner data to propose an ex-ante evaluation and comparison of these two policy options for the fromage blanc and dessert yogurt market. In most markets, labelling is voluntary and firms display fat labels only on the FOP of low-fat products to target consumers who do not want to eat fat. We here separately identify consumer preferences for fat and for FOP fat labels by exploiting an exogenous difference in legal labelling requirements between these two product categories. Estimates of demand curves are combined with a supply model of oligopolistic price competition to simulate policies. We find that a feasible ad valorem fat tax dominates a mandatory FOP-label policy from an economic perspective, but both are equally effective in reducing average fat purchases.

    2010-02-01

    Twenty Dorper x Pelibuey male lambs were used to evaluate the effect of substitution of forage with fresh orange pulp (FOP) in diets for fattening lambs on productive behavior, nutrient intake, apparent digestibility coefficient, and feeding costs. Lambs were divided into five groups (n = 4) and then housed in individual pens during 70 d. Treatments consisted of five levels of FOP (0, 25, 50, 75 and 100%) which substituted buffel grass hay on the base diet (40:60%, forage:concentrate). Additionally, changes in chemical composition of FOP stored in stack during 8 d were evaluated (from the day 1 until day 8). Daily feed intake expressed as kg/day and % live weight, lamb growth rate, feeding cost of each lamb per day and per fattening period, hemicellulose intake, and DM, OM, CP, NDF and hemicellulose digestibility showed a quadratic effect (P 0.05) among storage days. Therefore, replacing around 75% of buffel grass hay with FOP in diets for fattening lambs resulted in the best growth rate and more efficient diet utilization. Fresh orange pulp stored in a stack did not change its chemical composition, and did not affect its utilization as a sheep feedstuff.

  12. Groundwater level monitoring sampling and analysis plan for the environmental monitoring plan at waste area grouping 6, Oak Ridge National Laboratory, Oak Ridge, Tennessee

    1995-09-01

    This document is the Groundwater Level Monitoring Sampling and Analysis Plan (SAP) for Waste Area Grouping (WAG) 6 at Oak Ridge National Laboratory (ORNL). Note that this document is referred to as a SAP even though no sampling and analysis will be conducted. The term SAP is used for consistency. The procedures described herein are part of the Environmental Monitoring Plan (EMP) for WAG 6, which also includes monitoring tasks for seeps and springs, groundwater quality, surface water, and meteorological parameters. Separate SAPs are being issued concurrently to describe each of these monitoring programs. This SAP has been written for the use of the field personnel responsible for implementation of the EMP, with the intent that the field personnel will be able to take these documents to the field and quickly find the appropriate steps required to complete a specific task. In many cases, Field Operations Procedures (FOPs) will define the steps required for an activity. The FOPs for the EMP are referenced and briefly described in the relevant sections of the SAPs, and are contained within the FOP Manual. Both these documents (the SAP and the FOP Manual) will be available to personnel in the field

  14. Mesiodistal angulation of the lateral teeth to the functional occlusal plane in normal occlusions

    Hiroshi Ueda

    2016-01-01

    Full Text Available Introduction: Crowding is a malocclusion with irregularly positioned teeth caused by arch length discrepancy (ALD. Its incidence is high compared with the various malocclusions. In a previous study the crowns of the maxillary lateral teeth had erupted mesially in relation to the functional occlusal plane (FOP in patients with Angle Class I malocclusion and highly erupted canines, which had been uprighted by non-extraction orthodontic treatment, yet these results were based on only two cases evaluated by using plaster models. Therefore, the aim of this study was to assess the mesiodistal angulations of both maxillary and mandibular teeth relative to the FOP in normal occlusion by means of cephalograms and identifying the teeth axial factors contributing to the normal dentitions with the least ALD. Materials and Methods: Thirty Japanese young adult patients (6 males, 24 females with normal occlusion were selected to participate in this study; cephalograms were procured from each and the FOP was used as a reference plane for measuring the changes in the axial angulation along with other indicators of vertical growth. Results: Progressive mesial tipping of the maxillary lateral teeth was observed. First premolars tended to express this more than the second premolars but the tipping values were roughly 90° relative to the FOP on the first molars. Conclusion: The maxillary lateral teeth are more mesially angulated compared to the mandibular ones relative to the FOP. Furthermore, progressive mesial tipping of the maxillary lateral teeth was detected, of which axial angulations were significantly correlated to each other, in spite the mandibular premolars and molars being angulated in a similar fashion.

  15. Consumer acceptability and understanding of front-of-pack nutrition labels.

    2013-10-01

    Front-of-pack (FOP) nutrition labelling has been proposed as a tool for helping consumers make healthy choices. Before determining its effects on consumer behaviour, factors involved in its use must be elucidated, i.e. understanding and acceptability on the part of the consumer. Among five FOP labels, we sought to determine which formats were most easily understood and accepted by a large sample of adults. Among 39 370 adults who participated in the French Nutrinet-Santé cohort study, understanding and indicators of acceptability (attitude, liking, visual attractiveness and perceived cognitive workload) were measured for five FOP labels: The currently used 'multiple traffic lights' (MTL) and 'simple traffic lights' (STL), and the 'colour range' logo (CR), the 'green tick' and the PNNS logo. We investigated the contribution of the different elements to consumer perception of FOP labels using multiple correspondence analyses. Over half of the sample population showed a high level of understanding and perceived no discomfort in terms of the different logos. Label formats were positioned along an acceptability gradient ranging from acceptance to rejection, consisting of 'liking', 'attractiveness' and indicators of perceived cognitive workload. MTL was significantly more often liked and was viewed as reliable and informative. MTL, STL and the green tick performed better than the CR and PNNS logos in terms of ease of identification and comprehension. CR was clearly the least appreciated and it had the most complex format. Consumers prefer FOP labels which give complete, reliable and simplified information on the nutrient quality of foods. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

  16. [Fear of progression in parents of children with cancer: adaptation of the Fear of Progression Questionnaire and correlates].

    Schepper, F; Abel, K; Herschbach, P; Christiansen, H; Mehnert, A; Martini, J

    2015-05-01

    Fear of Progression (FoP), the fear of further disease progression, is one of the most common psychological strains of chronically ill patients and can also be found in healthy partners of cancer patients. Parents of children with cancer are also at risk of developing distinct fears that may persist after medical treatment. This study aimed to assess FoP in parents of children with cancer and to investigate relationships between FoP in parents of children with cancer and disease- and treatment-related issues, the child's current medical condition and parents' quality of life. In this study 76 parents (51 mothers, 25 fathers) whose children were in inpatient treatment or follow-up care were surveyed. The short form of the FoP Questionnaire was adapted by rephrasing the items for the parental perspective (FoP-Q-SF/PR). The FoP-Q-SF/PR is a short questionnaire with adequate psychometric properties (e. g. Cronbach's α=0.90) and satisfying results in terms of construct validity. Significant correlations with FoP are found for the child's current medical condition (r=0.35), time since diagnosis (r=- 0.30), parents' capacity to cope with disease-related fears (r=- 0.45) and parents' quality of life (r=- 0.55). A cut-off value of 46 points is recommended. The FoP-Q-SF/PR offers a feasible and sensitive battery to assess disease-related fears. For clinicians, evaluation of individual results can provide insight into specific problem areas for parents of children with cancer. The questionnaire is thus well suited for use in psychosocial care of families within the field of paediatric oncology. © Georg Thieme Verlag KG Stuttgart · New York.

    To evaluate the sensitivity and specificity of "fundus on phone' (FOP) camera, a smartphone based retinal imaging system, as a screening tool for diabetic retinopathy (DR) detection and DR severity in comparison with 7-standard field digital retinal photography. Single-site, prospective, comparative, instrument validation study. 301 patients (602 eyes) with type 2 diabetes underwent standard seven-field digital fundus photography with both Carl Zeiss fundus camera and indigenous FOP at a tertiary care diabetes centre in South India. Grading of DR was performed by two independent retina specialists using modified Early Treatment of Diabetic Retinopathy Study grading system. Sight threatening DR (STDR) was defined by the presence of proliferative DR(PDR) or diabetic macular edema. The sensitivity, specificity and image quality were assessed. The mean age of the participants was 53.5 ±9.6 years and mean duration of diabetes 12.5±7.3 years. The Zeiss camera showed that 43.9% had non-proliferative DR(NPDR) and 15.3% had PDR while the FOP camera showed that 40.2% had NPDR and 15.3% had PDR. The sensitivity and specificity for detecting any DR by FOP was 92.7% (95%CI 87.8-96.1) and 98.4% (95%CI 94.3-99.8) respectively and the kappa (ĸ) agreement was 0.90 (95%CI-0.85-0.95 p<0.001) while for STDR, the sensitivity was 87.9% (95%CI 83.2-92.9), specificity 94.9% (95%CI 89.7-98.2) and ĸ agreement was 0.80 (95%CI 0.71-0.89 p<0.001), compared to conventional photography. Retinal photography using FOP camera is effective for screening and diagnosis of DR and STDR with high sensitivity and specificity and has substantial agreement with conventional retinal photography.

On conventional radiography, the lesion demonstrated a spherically trabeculated mass with a calcific rim. On CT scan, it showed a well-organized peripheral calcification resembling a myositis ossificans. On MRI, it presented as a multilocular, cystic lesion with fluid-fluid levels. The lesion had no solid components except for intralesional septa. Although findings on imaging and histology were identical to those described in classical aneurysmal bone cyst, diagnosis was delayed because of lack of knowledge of this entity and its resemblance to the more familiar post-traumatic heterotopic ossification (myositis ossificans).

  1. Extraarticular bony ankylosis in a child with supracondylar fracture of humerus

    Naranje Sameer

    2012-11-01

    Full Text Available 【Abstract】 Myositis ossificans is defined as forma-tion of bone at the site of injured muscle. It is one of the rare complications of supracondylar fracture of humerus in children. Myositis mass usually develops on the anterior aspect in the brachialis muscle and produces restriction of range of motion, but complete ankylosis is rare. To the best of our knowledge, this is the first case to be reported in the literature as a consequence of myositis ossificans traumatica. In this case, a six-year-old child presented to the casualty department with pain in the right elbow after a fall on out-stretched hand during play. After surgical excision through the anterior approach, the child had no symptoms referable to the elbow and a residual flexion deformity of 15 degrees with further painless flexion up to 100 degrees at last follow-up of one year after surgery.

  2. Unexpected radionuclide uptake due to calcification in muscles

    Khier, A.

    1999-01-01

    Full text: A male patient aged 27 years was injected with 1000 MBq of 99 Tc m -MDP. The patient was an active man indulging in contact sport. He presented with lower back and pelvic pain. Spot pictures were made of the pelvis, lumbar spine and femurs. Unexpected active radionuclide uptake in the muscles was seen. In the delayed static images, there was focal accumulation of tracer uptake in the muscles overlying the mid-shaft of the left femur consistent with myositis ossificans. Myositis ossificans is a benign ossifying process that is generally solitary and well circumscribed. It is most commonly found in the muscles but it may occur in other connective tissues, especially tendons and subcutaneous fat. This was presumably associated with chronic muscular injuries contracted during sports activity

    Injuries to skeletal muscle are very common particularly in athletes. Besides ultrasound, MR imaging represents the most valuable imaging modality for diagnosis and grading of muscle lesions. This article reviews the examination technique and diagnostic criteria of acute and chronic lesions of skeletal muscle at MR imaging. In addition to the morphology of direct and indirect muscle injuries, MR findings in myositis ossificans and compartment syndrome are discussed as well.

    Focal myositis is a pseudotumor of soft tissue that typically occurs in the deep soft tissue of the extremities, and is a relatively rare lesion. There is a wide clinical spectrum, with approximately one-third of patients with focal myositis subsequently developing polymyositis, and clinical symptoms of generalized weakness, fever, myalgia, and weight loss, with elevation of creatine phosphokinase. We report the case of a patient with focal myositis who subsequently developed myositis ossificans-like features. (orig.)

    Fault permeability is known to depend strongly on stress and fluid pressures. Exponential relationships between permeability and effective pressure have been proposed to approximate fault response to fluid pressure variations. However, the applicability of these largely empirical laws remains questionable, as they do not take into account shear stress and shear strain. A series of experiments using mHPP probes have been performed within fault zones in very low permeability (less than 10-19 m2) Lower Jurassic shale formations at Tournemire (France) and Mont Terri (Switzerland) underground laboratories. These probes allow to monitor 3D displacement between two points anchored to the borehole walls at the same time as fluid pressure and flow rate. In addition, in the Mont-Terri experiment, passive pressure sensors were installed in observation boreholes. Fracture transmissivity was estimated from single borehole pulse test, constant pressure injection tests, and cross-hole tests. It is found that the transmissivity-pressure dependency can be approximated with an exponential law, but only above a pressure threshold that we call the Fracture Opening Threshold (F.O.P). The displacement data show a change of the mechanical response across the F.O.P. The displacement below the F.O.P. is dominated by borehole response, which is mostly elastic. Above F.O.P., the poro-elasto-plastic response of the fractures dominates. Stress determinations based on previous work and on the analysis of slip data from mHPPP probe indicate that the F.O.P. is lower than the least principal stress. Below the F.O.P., uncemented fractures retain some permeability, as pulse tests performed at low pressures yield diffusivities in the range 10-2 to 10-5 m2/s. Overall, this dual behavior appears consistent with the results of CORK experiments performed in accretionary wedge decollements. Results suggest (1) that fault zones become highly permeable when approaching the critical Coulomb threshold (2

    To investigate patients' reasons for selecting a dental clinic given their choice of free or highly-subsidized dental services. The study was based on cross-sectional data obtained through phone interviews with adults in Tehran, Iran. The present study included those entitled to free or highly-subsidized dental services (n = 726). The data covered the patients' awareness of subsidized dental services and type of dental clinic for their most recent visit and their reasons for selecting that clinic. Awareness of subsidized dental services was dichotomized as being either aware or unaware of such subsidy. The type of clinic was dichotomized as providing either free or highly-subsidized (FHS) or fully out-of-pocket paid (FOP) services. Free format answers about the subjects' reasons for selecting a particular clinic were later sub-grouped as: convenient access, good technical aspects, good interpersonal aspects, low or reasonable fees, recommendation by a friend, and no reason. Socio-demographic status was based on background. Data analysis included the chi-square test and logistic regression model. Of the subjects (n = 726), 60% were women and 58% were under 35 years of age. The subjects' mean age was 33.5 years with no difference by gender (P = 0.24) and the majority had public insurance (91%). Of all the subjects, 60% selected FOP. Good interpersonal aspects were the strongest reason for selecting FOP (OR = 4.6), follow by good technical aspects (OR = 2.3). Those subjects who were unaware of their benefit had 4.6 times the odds of selecting FOP. Despite the opportunity to use highly-subsidized dental services, good interpersonal and good technical aspects lead patients to select private dentists and to pay fully out of pocket.

    To date, no consensus has emerged on the most appropriate front-of-pack (FOP) nutrition label to help consumers in making informed choices. We aimed to compare the effectiveness of the label formats currently in use: nutrient-specific, graded and simple summary systems, in a large sample of adults. The FOP label effectiveness was assessed by measuring the label acceptability and understanding among 13,578 participants of the NutriNet-Santé cohort study, representative of the French adult population. Participants were exposed to five conditions, including four FOP labels: Guideline Daily Amounts (GDA), Multiple Traffic Lights (MTL), 5-Color Nutrition Label (5-CNL), Green Tick (Tick), and a "no label" condition. Acceptability was evaluated by several indicators: attractiveness, liking and perceived cognitive workload. Objective understanding was assessed by the percentage of correct answers when ranking three products according to their nutritional quality. Five different product categories were tested: prepared fish dishes, pizzas, dairy products, breakfast cereals, and appetizers. Differences among the label effectiveness were compared with chi-square tests. The 5-CNL was viewed as the easiest label to identify and as the one requiring the lowest amount of effort and time to understand. GDA was considered as the least easy to identify and to understand, despite being the most attractive and liked label. All FOP labels were found to be effective in ranking products according to their nutritional quality compared with the "no label" situation, although they showed differing levels of effectiveness (p<0.0001). Globally, the 5-CNL performed best, followed by MTL, GDA and Tick labels. The graded 5-CNL label was considered as easy to identify, simple and rapid to understand; it performed well when comparing the products' nutritional quality. Therefore, it is likely to present advantages in real shopping situations where choices are usually made quickly.

  12. Understanding pea resistance mechanisms in response to Fusarium oxysporum through proteomic analysis.

    Castillejo, María Ángeles; Bani, Moustafa; Rubiales, Diego

    2015-07-01

    Fusarium oxysporum f. sp. pisi (Fop) is an important and destructive pathogen affecting pea crop (Pisum sativum) throughout the world. Control of this disease is achieved mainly by integration of different disease management procedures. However, the constant evolution of the pathogen drives the necessity to broaden the molecular basis of resistance to Fop. Our proteomic study was performed on pea with the aim of identifying proteins involved in different resistance mechanisms operating during F. oxysporum infection. For such purpose, we used a two-dimensional electrophoresis (2-DE) coupled to mass spectrometry (MALDI-TOF/TOF) analysis to study the root proteome of three pea genotypes showing different resistance response to Fop race 2. Multivariate statistical analysis identified 132 differential protein spots under the experimental conditions (genotypes/treatments). All of these protein spots were subjected to mass spectrometry analysis to deduce their possible functions. A total of 53 proteins were identified using a combination of peptide mass fingerprinting (PMF) and MSMS fragmentation. The following main functional categories were assigned to the identified proteins: carbohydrate and energy metabolism, nucleotides and aminoacid metabolism, signal transduction and cellular process, folding and degradation, redox and homeostasis, defense, biosynthetic process and transcription/translation. Results obtained in this work suggest that the most susceptible genotypes have increased levels of enzymes involved in the production of reducing power which could then be used as cofactor for enzymes of the redox reactions. This is in concordance with the fact that a ROS burst occurred in the same genotypes, as well as an increase of PR proteins. Conversely, in the resistant genotype proteins responsible to induce changes in the membrane and cell wall composition related to reinforcement were identified. Results are discussed in terms of the differential response to Fop

    2014-01-01

    Background and aim Although it is known that case management for frail older persons (FOP) is more likely to foster positive outcomes when the case manager works closely with the primary care physicians (PCP) [1], engaging PCPs to collaborate is often a difficult process, especially when the case management function is new [2]. The aim of this study was to provide insight on how newly implemented case management projects managed to engage FOPs’ PCP in the case management process, (to what ext...

    2015-07-01

    Parents caring for a child with a chronic somatic condition are at risk of increased distress and impaired quality of life. Fear of disease progression (FoP) is known to be an important source of distress in patients and their partners, and may be of relevance for parents as well. Existing measures are not applicable to parents. This study describes the adaptation of the FoP questionnaire for parental caregivers and investigated its psychometric properties. Sixteen items appropriate for parents were derived from existing measures and from interviews with clinical experts in family-oriented psychosocial care. Factor structure, internal consistency, validity and sensitivity to change were analyzed in a clinical sample of 162 caregivers (M(age)=42.07 years, SD=6.0 years, 87.8% female) of a child with cystic fibrosis. The exploratory factor analysis reveal ed a two-factor structure, which was not supported by confirmatory analysis. Cronbach's α was examined for total score (.91) and significant positive correlations of the total score with anxiety (HADS: r=.70) and depression (CES-D: r=.60, BDI-II: r=.59), and a significant negative correlations with quality of life (r=-.66) could be demonstrated. A significant decrease in FoP was found (d=1.11) in a group of highly distressed caregivers undergoing web-based cognitive behavioral intervention. The FoP questionnaire is a reliable and valid instrument for parents of children with CF. Further studies in larger samples are needed to clarify dimensionality and validity among parents of children with other chronic conditions. Copyright © 2015 Elsevier Inc. All rights reserved.

    Incremental Programming (IP) is a programming style in which new program components are defined as increments of other components. Examples of IP mechanisms include: Object-oriented programming (OOP) inheritance, aspect-oriented programming (AOP) advice and feature-oriented programming (FOP). A characteristic of IP mechanisms is that, while individual components can be independently defined, the composition of components makes those components become tightly coupled, sh...

  1. Impact of Added Sugar Information of Front-of-Pack Labels on Consumers’ Beverage Health Perception Changes

    Kim, Hyeyoung; House, Lisa

    2012-01-01

    This study examined the effect of Front-of-package (FOP) labels with voluntary and mandatory disclosure of added sugar levels for beverages on consumer perceptions of how healthy the beverages are. Three groups of beverages were investigated: 1) 100% fruit juice (containing sugar but no added sugar); 2) sugar-sweetened beverages (containing sugar and added sugar); and 3) diet soft drink (containing no sugar). In general, added sugar information seems to play an important role in perception of...

    2018-02-01

    Front-of-package (FOP) marketing strategies of a wide variety of beverages were catalogued to examine the prevalence of each strategy prior to a sweeping Chilean restriction of child-directed marketing aimed at reducing obesity-related disease among Chile's youth. Photographs of 1005 beverage packages were quantitatively content-analysed to code whether a variety of child-directed, health-oriented and other marketing strategies (e.g. sales promotions) were present on each product's FOP. Strategies were then analysed based on beverages' product category, total sugar, energy and tax status (beverages with added sugars are taxed at different rates). Photographs were taken in six urban supermarkets in Santiago, Chile, representing five different supermarket chains. Beverages using child-directed characters or nature/fruit references were higher in total sugar and beverages with child-directed characters or childhood/family references were higher in energy than beverages without these respective strategies. Of the beverages taxed at the highest rate (greatest amount of added sugars), 49 % used nutrition and health appeals and 80 % used nature or fruit appeals. Plain waters and plain milks were less likely than other selected product categories to use health-oriented appeals or multiple FOP strategies in combination. FOP marketing on beverages varied according to the nutritional quality of the product, with heavier use of health-oriented and child-directed strategies in less healthy products. Marketing activities warrant continued observation to evaluate how industry responds to new marketing restrictions as these restrictions are evaluated in the light of existing taxes and other regulatory efforts to improve diets and reduce obesity-related disease.

  3. Association of perception of front-of-pack labels with dietary, lifestyle and health characteristics.

    Caroline Méjean

    Full Text Available OBJECTIVE: To identify patterns of perception of front-of-pack (FOP nutrition labels and determine dietary, lifestyle and health profiles related to such patterns. DESIGN: Cross-sectional. PARTICIPANTS/SETTING: 28,952 French adults participating in the web-based Nutrinet-Santé cohort. OUTCOME MEASURES: Perception was measured using indicators of understanding and acceptability for three simple FOP labels ("green tick", the logo of the French Nutrition and Health Program and "simple traffic lights" (STL, and two detailed FOP formats ("multiple traffic lights" (MTL and "color range" logo (CR, placed on ready-to-eat soup packages. Dietary intake data were collected using three web-based 24 h records. STATISTICAL ANALYSES: Associations of perception patterns with individual characteristics, including diet, lifestyle and health status, were examined using analysis of covariance and logistic regression, adjusted for socio-demographic and economic factors. RESULTS: No clear trend emerged concerning differences in dietary intake between perception groups. Low physical activity and obesity were more frequent in the 'favorable to STL' group (respectively, 20.7% and 10.7%. The 'favorable to MTL' group included the highest percentage of individuals who declared type 2 diabetes (2.2%. Persons with hypertension were proportionally more numerous in the 'favorable to MTL' and the 'favorable to CR logo' groups (respectively, 9.5% and 9.3%. CONCLUSIONS: After adjustment for socio-demographic and economic factors, no FOP label stood out as being more suitable than another for reaching populations with poor diet. However, both STL and MTL may be most appropriate for increasing awareness of healthy eating among groups at higher risk of nutrition-related chronic diseases.

  5. Dual-process theory and consumer response to front-of-package nutrition label formats.

    Sanjari, S Setareh; Jahn, Steffen; Boztug, Yasemin

    2017-11-01

    Nutrition labeling literature yields fragmented results about the effect of front-of-package (FOP) nutrition label formats on healthy food choice. Specifically, it is unclear which type of nutrition label format is effective across different shopping situations. To address this gap, the present review investigates the available nutrition labeling literature through the prism of dual-process theory, which posits that decisions are made either quickly and automatically (system 1) or slowly and deliberately (system 2). A systematically performed review of nutrition labeling literature returned 59 papers that provide findings that can be explained according to dual-process theory. The findings of these studies suggest that the effectiveness of nutrition label formats is influenced by the consumer's dominant processing system, which is a function of specific contexts and personal variables (eg, motivation, nutrition knowledge, time pressure, and depletion). Examination of reported findings through a situational processing perspective reveals that consumers might prefer different FOP nutrition label formats in different situations and can exhibit varying responses to the same label format across situations. This review offers several suggestions for policy makers and researchers to help improve current FOP nutrition label formats. © The Author(s) 2017.

    In the ongoing debate about front-of-package (FOP) nutrition labels, little data exist regarding nutritionally at-risk populations, although they are critical targets of prevention programs. This study aimed to compare the impact of FOP labels on the ability to rank products according to their nutritional quality among French adults potentially at risk of poor dietary quality (N = 14,230). Four labels were evaluated: Guideline Daily Amounts (GDA), Multiple Traffic Lights (MTL), 5-Color Nutrition Label (5-CNL), Green Tick (Tick), along with a reference without label. Mixed models were used to assess how individual characteristics and FOP labels were associated with the ability to rank products. Older participants and those with a lower educational level, income, nutritional knowledge, and likelihood of reading nutrition facts were less skilled at ranking food products according to nutritional quality. Compared with individual characteristics, nutrition labels had an increased impact on food product ranking ability. Overall, 5-CNL corresponded to the highest rate of correct responses, followed by MTL, GDA, and Tick (p < 0.0001). The strongest impact of 5-CNL was observed among individuals with no nutritional knowledge (odds ratio (OR): 20.24; 95% confidence interval (CI): 13.19-31.06). Therefore, 5-CNL appeared to be effective at informing consumers, including those who are nutritionally at-risk, about the nutritional quality of food products.

  7. Generalized finite polynomial approximation (WINIMAX) to the reduced partition function of isotopic molecules

    Lee, M.W.; Bigeleisen, J.

    1978-01-01

    The MINIMAX finite polynomial approximation to an arbitrary function has been generalized to include a weighting function (WINIMAX). It is suggested that an exponential is a reasonable weighting function for the logarithm of the reduced partition function of a harmonic oscillator. Comparison of the error function for finite orthogonal polynomial (FOP), MINIMAX, and WINIMAX expansions of the logarithm of the reduced vibrational partition function show WINIMAX to be the best of the three approximations. A condensed table of WINIMAX coefficients is presented. The FOP, MINIMAX, and WINIMAX approximations are compared with exact calculations of the logarithm of the reduced partition function ratios for isotopic substitution in H 2 O, CH 4 , CH 2 O, C 2 H 4 , and C 2 H 6 at 300 0 K. Both deuterium and heavy atom isotope substitution are studied. Except for a third order expansion involving deuterium substitution, the WINIMAX method is superior to FOP and MINIMAX. At the level of a second order expansion WINIMAX approximations to ln(s/s')f are good to 2.5% and 6.5% for deuterium and heavy atom substitution, respectively

  8. Feature-opinion pair identification of product reviews in Chinese: a domain ontology modeling method

    Yin, Pei; Wang, Hongwei; Guo, Kaiqiang

    2013-03-01

    With the emergence of the new economy based on social media, a great amount of consumer feedback on particular products are conveyed through wide-spreading product online reviews, making opinion mining a growing interest for both academia and industry. According to the characteristic mode of expression in Chinese, this research proposes an ontology-based linguistic model to identify the basic appraisal expression in Chinese product reviews-"feature-opinion pair (FOP)." The product-oriented domain ontology is constructed automatically at first, then algorithms to identify FOP are designed by mapping product features and opinions to the conceptual space of the domain ontology, and finally comparative experiments are conducted to evaluate the model. Experimental results indicate that the performance of the proposed approach in this paper is efficient in obtaining a more accurate result compared to the state-of-art algorithms. Furthermore, through identifying and analyzing FOPs, the unstructured product reviews are converted into structured and machine-sensible expression, which provides valuable information for business application. This paper contributes to the related research in opinion mining by developing a solid foundation for further sentiment analysis at a fine-grained level and proposing a general way for automatic ontology construction.

    2010-01-01

    This study investigated the fear of progression (FoP) in cancer patients and the discriminant ability of the Fear of Progression Questionnaire (FoP-Q) against the Hospital Anxiety and Depression Scale (HADS), while also examining relationships between FoP, satisfaction outcomes and supportive needs. The FoP-Q and HADS were administered to 112 cancer patients in Korea during June and July 2006. The FoP-Q totals and subscales, and the HADS scores were compared across three groups (patients with recurrence, patients with metastases and controls experiencing neither). Comparison of the FoP-Q total score to HADS anxiety (HADS-A) and depression (HADS-D) scores showed higher FoP in the recurrence group compared to the control group (P=.009). Subscale score comparisons revealed a heightened "affective reaction" (P=.003) to cancer progression and fear of "loss of autonomy" (P=.011) in recurrence patients. FoP-Q score showed a moderate association with HADS-A (r=.54, P=.000) and a significant association with treatment satisfaction (r=-.26, P=.007), medical staff and communication (r=-.31, P=.001), and supportive needs (r=.41, P=.000). The importance of providing supportive interventions tailored to the specific emotional concerns of cancer patients, assessed via appropriate, disease-specific instruments, and the need to pay special attention to the concerns of recurrence patients are suggested.

  11. Fear of progression in chronic diseases: psychometric properties of the Fear of Progression Questionnaire.

    Herschbach, Peter; Berg, Petra; Dankert, Andrea; Duran, Gabriele; Engst-Hastreiter, Ursula; Waadt, Sabine; Keller, Monika; Ukat, Robert; Henrich, Gerhard

    2005-06-01

    The aim of this study was the development and psychometric testing of a new psychological questionnaire to measure the fear of progression (FoP) in chronically ill patients (cancer, diabetes mellitus and rheumatic diseases). The Fear of Progression Questionnaire (FoP-Q) was developed in four phases: (1) generation of items (65 interviews); (2) reduction of items--the initial version of the questionnaire (87 items) was presented to 411 patients, to construct subscales and test the reliability; (3) testing the convergent and discriminative validity of the reduced test version (43 items) within a new sample (n=439); (4) translation--German to English. The scale comprised five factors (Cronbach's alpha >.70): affective reactions (13 items), partnership/family (7), occupation (7), loss of autonomy (7) and coping with anxiety (9). The test-retest reliability coefficients varied between .77 and .94. There was only a medium relationship to traditional anxiety scales. This is an indication of the independence of the FoP. Significant relationships between the FoP-Q and the patient's illness behaviour indicate discriminative validity. The FoP-Q is a new and unique questionnaire developed for the chronically ill. A major problem and source of stress for this patient group has been measuring both specifically and economically the FoP of an illness. The FoP-Q was designed to resolve this problem, fulfill this need and reduce this stress.

    Full Text Available A Mexican Committee of Nutrition Experts (MCNE from the National Institute of Public Health (INSP, free from conflict of interest, established food content standards to place the front-of-package (FOP logo on foods that meet these nutrition criteria. The objectives were to simulate the effect on nutrient intake in the Mexican adult population (20–59 years old after replacing commonly consumed processed foods with those that meet the FOP nutrition-labeling criteria. Twenty-four hour dietary recalls were collected from the 2012 Mexican National Health and Nutrition Survey (n = 2164 adults. A food database from the INSP was used. Weighted medians and 25–75 inter-quartile ranges (IQR of energy and nutrient intake were calculated for all subjects by sociodemographic characteristics before and after replacing foods. Significant decreases were observed in energy (−5.4%, saturated fatty acids (−18.9%, trans-fatty acids (−20%, total sugar (−36.8% and sodium (−10.7% intake and a significant increase in fiber intake (+15.5% after replacing foods, using the MCNE nutrition criteria. Replacing commonly consumed processed foods in the diet with foods that meet the FOP nutrition-labeling criteria set by the MCNE can lead to improvements in energy and nutrient intake in the Mexican adult population.

    2014-06-25

    The inclination of the occlusal plane (OP) is related to facial types and experiences physiological growth-related changes. The aims of this research were to determine if there were any differences in the inclination of OP in subjects with three types of skeletal malocclusion and to investigate the characteristics and differences of functional occlusal plane (FOP) compared to bisected occlusal plane (BOP). A sample of 90 Caucasians patients was skeletal-classified into three (n = 30), and pre- and post-treatment cephalograms were digitized. Six linear and 8 angular cephalometric measurements were selected. The changes of OP inclination within each group and the differences among the three groups pre- and post-treatment were compared with paired t test and ANOVA test, respectively. The comparison and correlation between BOP and FOP were analyzed with paired t test and coefficient of correlation, respectively. The BOP angle increased in all of the three groups but only had statistically significant differences in skeletal class II patients in a mean of 1.51° (p stability (p > 0.05) in all three groups. The inclination of FOP was closely related to that of BOP (p stability in orthodontically treated patients with all three skeletal patterns.

  14. Predicting success of oligomerized pool engineering (OPEN for zinc finger target site sequences

    Goodwin Mathew J

    2010-11-01

    Full Text Available Abstract Background Precise and efficient methods for gene targeting are critical for detailed functional analysis of genomes and regulatory networks and for potentially improving the efficacy and safety of gene therapies. Oligomerized Pool ENgineering (OPEN is a recently developed method for engineering C2H2 zinc finger proteins (ZFPs designed to bind specific DNA sequences with high affinity and specificity in vivo. Because generation of ZFPs using OPEN requires considerable effort, a computational method for identifying the sites in any given gene that are most likely to be successfully targeted by this method is desirable. Results Analysis of the base composition of experimentally validated ZFP target sites identified important constraints on the DNA sequence space that can be effectively targeted using OPEN. Using alternate encodings to represent ZFP target sites, we implemented Naïve Bayes and Support Vector Machine classifiers capable of distinguishing "active" targets, i.e., ZFP binding sites that can be targeted with a high rate of success, from those that are "inactive" or poor targets for ZFPs generated using current OPEN technologies. When evaluated using leave-one-out cross-validation on a dataset of 135 experimentally validated ZFP target sites, the best Naïve Bayes classifier, designated ZiFOpT, achieved overall accuracy of 87% and specificity+ of 90%, with an ROC AUC of 0.89. When challenged with a completely independent test set of 140 newly validated ZFP target sites, ZiFOpT performance was comparable in terms of overall accuracy (88% and specificity+ (92%, but with reduced ROC AUC (0.77. Users can rank potentially active ZFP target sites using a confidence score derived from the posterior probability returned by ZiFOpT. Conclusion ZiFOpT, a machine learning classifier trained to identify DNA sequences amenable for targeting by OPEN-generated zinc finger arrays, can guide users to target sites that are most likely to function

    In part I, we reviewed the varied clinical presentations, pathogenesis, histologic findings, radiologic findings, and treatment of intramedullary cartilaginous lesions of bone. In this section, we will evaluate our cases and consultations of juxtacortical cartilaginous tumors. Radiographic differential diagnosis includes the numerous juxtacortical lesions particularly osteochondroma, parosteal chondroma, Trevor's disease, trauma (fracture and periostitis ossificans), and the low- and high-grade surface osteosarcomas. By emphasizing pathogenesis in conjunction with radiographic and histologic findings, pitfalls in diagnosis and subsequent treatment can be avoided in such cases. (orig.)

  16. MR imaging of soft tissue tumors and tumor-like lesions

    2004-01-01

    The evaluation of a soft tissue mass in a child should proceed with a differential diagnosis in mind, based on the clinical history, age of the child, and location of the abnormality. Small, superficial masses can be initially evaluated with sonography. More extensive or deep lesions usually require cross-sectional imaging. With the exception of myositis ossificans, magnetic resonance (MR) imaging has largely replaced the use of computed tomography. MR imaging is used to delineate the extent of a lesion, to evaluate response to therapy, and to monitor postoperative complications. There is great overlap in the MR imaging characteristics of benign and malignant lesions, making tissue sampling imperative for diagnosis. (orig.)

    2015-01-01

    Full Text Available Introduction. Rotator cuff intramuscular calcification is a rare condition usually caused by heterotopic ossification and myositis ossificans. Case Presentation. We describe a patient with voluminous calcified mass entrapped in supraspinatus muscle associated with corresponding tendon tear. Histological examination corresponded to a calcified hematoma or necrosis. Patient was surgically managed with open excision of the calcified hematoma and rotator cuff arthroscopic repair. At 6 months, supraspinatus muscle was healed, and functional outcome was good. Discussion and Conclusion. We hypothesized that supraspinatus intramuscular calcified hematoma was responsible for mechanical stress on the tendon. This association has never been described.

    Osteoblastomas located on the surface of the cortical bone, so-called periosteal osteoblastomas, are extremely rare. We report on a case of periosteal osteoblastoma arising from the posterior surface of the right distal femur in a 17-year-old man. Roentgenographic, computed tomographic, magnetic resonance imaging, and histologic features of the case are presented. Periosteal osteoblastoma should be radiologically and histologically differentiated from myositis ossificans, avulsive cortical irregularity syndrome, osteoid osteoma, parosteal osteosarcoma, periosteal osteosarcoma, and high-grade surface osteosarcoma. Although periosteal osteoblastoma is rare, this tumor should be included in the differential diagnosis of surface-type bone tumors. (orig.)

    Noninfectious, nonneoplastic reactive processes of the hand, such as myositis ossificans circumscripta, pseudomalignant osseous tumor of soft tissue, and florid reactive periostitis, appear similar radiologically and histologically and are often difficult to differentiate. Magnetic resonance (MR) findings in two such lesions are reported. The extensive reactive change in the extraosseous soft tissue and the bone marrow and the relatively small extent of ossification may be characteristic. Although low-grade infection and small osseous neoplasms with reactive changes, such as osteoid osteoma, may still remain possible causes, MR imaging provides essential evidence for including noninfective, nonneoplastic reactive processes of uncertain cause in the list of differential diagnoses.

  20. A Unique Case of Melorheostosis Presenting with Two Radiologically Distinct Lesions in the Shoulder

    Ahmed A. Elsheikh

    2017-01-01

    Full Text Available Melorheostosis is a rare, nonhereditary, benign, mesenchymal condition of unknown aetiology affecting the bones and surrounding tissues. A male patient complaining of left shoulder pain, swelling, and mildly limited range of motion has an exclusive combination of the classic dripping wax lesion in the scapula and the myositis ossificans-like lesion in the deltoid muscle; this combination is the first to be reported in the shoulder. Both lesions showed typical findings of melorheostosis in radiographs, CT, MRI, and bone scan. This case has a stationary course over the follow-up period, and no specific treatment is needed in due course.

  1. Fine needle aspiration cytology of pseudosarcomatous reactive lesions of soft tissues: A report of two cases

    Suchitha Satish

    2012-01-01

    Full Text Available Pseudosarcomatous lesions are reactive proliferative lesions of the soft tissue, that are likely to be misdiagnosed as malignant, based on clinical and histological features. The most common lesions are nodular fasciitis, proliferative fasciitis, proliferative myositis and myositis ossificans. These rapidly growing soft-tissue lesions can represent a variety of diagnoses involving radically different treatment modalities. Accurate diagnosis is important to avoid unnecessary and often mutilating surgery. We report two cases to illustrate the importance of correct identification of these lesions by fine needle aspiration cytology.

    Focal myositis is a pseudotumor of soft tissue that typically occurs in the deep soft tissue of the extremities, and is a relatively rare lesion. There is a wide clinical spectrum, with approximately one-third of patients with focal myositis subsequently developing polymyositis, and clinical symptoms of generalized weakness, fever, myalgia, and weight loss, with elevation of creatine phosphokinase. We report the case of a patient with focal myositis who subsequently developed myositis ossificans-like features. (orig.) With 3 figs., 25 refs.

    Ultrasound is the first step imaging investigation for the evaluation of muscle injuries and pathologies, even better than MRI for repairing processes study and rehabilitation program's assessment. The key sign of a muscular tear is hematoma, whose formation is lasting between 2 and 48 hours from injury. US supports the analysis of its evolving patterns, early detecting complications such as cystic lesions or myositis ossificans too. It also provides dynamic details of muscle fibers, tendons and aponeurosis, that all of the other instrumental investigation can't offer.

    1990-01-01

    Temporal bone CT was done in 697 patients from April 1985 to October 1989. The abnormal findings were seen in 453 patients, which were chronic otitis media in 355 patients, fracture in 49 patients and congenital anomaly in 44 patients, etc. The abnormal findings of inner ear were observed on 46 patients. The results were summarized as follows : 1. The incidence of inner ear involvement by chronic otitis media was 7.3% (26/355 : labyrinthine fistula in 17 patients, labyrinthitis ossificans in 9 patients). Labyrinthine fistula was most commonly located on lateral semicircular canal (15/17, 88.2%). 2. Fusion of vestibule with lateral semicircular canal and formation of common cavity was demonstrated incidentally in 5 patients (0.7% of total number of temporal bone CT), and bilateral in 3 patients. 3. The incidence of inner ear anomaly in congenital ear anomaly was 11.4% (5/44). All cases were bilateral and three patients showed associated middle ear anomaly. 4. The incidence of involvement of bony labyrinth in temporal bone fracture was 10.2% (5/49). Labyrinthine fracture was seen all patients of transverse(3) and mixed fracture(1). In longitudinal fracture, labyrinthine fracture was seen in 2.2% (1/45). 5. Others were traumatic labyrinthitis ossificans(1), intracanalicular acoustic neuroma(3) and facial nerve neuroma(1)

    Focal myositis is a rare benign inflammatory pseudotumor, presenting as a painful nodular mass within a muscle, and characterized by spontaneous resolution within weeks. To assess the clinical and imaging findings of focal nodular myositis simulating a neoplasm at clinical examination, with no history of trauma. This study describes the locations and appearance at ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) of this condition in a series of five patients. MRI and US displayed a solid intramuscular “tumor” and suggested a continuum between the proximal and distal muscle fibers that appeared thickened within the nodular lesion, a sign that has been reported in myositis ossificans. MRI showed edema in adjacent muscles and soft tissues, as well as intense enhancement of the mass. Intense vascular flows were seen at Doppler analysis. CT did not reveal the appearance of peripheral ossifications, ruling out the diagnosis of myositis ossificans. In some patients, the diagnosis of sarcoma had been suggested as possible by the radiologist. Imaging follow-up with MRI showed complete resolution of the masses over several weeks, thus avoiding a biopsy; no recurrence was observed at long-term follow-up (more than 24 months). This paper highlights MRI and US findings in focal non-ossifying myositis, and emphasizes the role of MRI in suggesting this diagnosis, leading to the careful follow-up of the lesion until its resolution, and ruling out more aggressive lesions

  9. Violence against women by male partners and against children within the family: prevalence, associated factors, and intergenerational transmission in Romania, a cross-sectional study.

    Domestic violence is a public health problem with negative consequences. We aimed to determine the prevalence of violence between parents and by parents against children, types of intimate partner violence against women, the intergenerational transmission of violence, and to identify a profile of beliefs and judgements regarding violent behaviour. The data used for this article were sourced from three cross-sectional studies performed in Romania in 2009-2011. We sampled 869 respondents (male and female) with a homogenous distribution between environment, gender, educational level, and age group (18 to 75). From a 96-item questionnaire regarding family and reproductive health, this article refers to four items: (1) feelings relating to the family in which they were raised; (2) whether they witnessed violence between parents or were victims of violence by parents or other family members during childhood or the teenage years; (3) opinions relating to 10 statements on violence from Maudsley Violence Questionnaire; (4) the manifestation of psychological, emotional, and sexual abuse from the partner in the family of procreation (FOP). The data were analysed by Pearson chi-square tests and latent class analysis. During childhood, 35% of respondents witnessed parental violence and 53.7% were victims of family violence. Psychological abuse by men against women was the most common type of violence reported in the FOP (45.1%). Violence in childhood and adolescence correlated with the perception of the family of origin as a hostile environment and of violence against women as a corrective measure, and that insults, swearing, and humiliation by their partner within the FOP is acceptable (p violence or were victims of violence during childhood (p violence as a form of discipline or instruction of children and women remains a significant problem, with a higher rate of intimate partner violence than in other developed countries.

  10. Ignorance is bliss. How parents of preschool children make sense of front-of-package visuals and claims on food.

    2015-04-01

    With growing scrutiny over how the food industry advertises products aimed toward children and fewer consumers using nutrition facts panels and ingredient lists, the fronts of food packages have become an increasingly important marketing tool to understand. Front-of-package (FOP) visual and verbal claims play a critical role in capturing consumers' attention and helping them choose foods that fit their goals. Due to only possessing emergent literacy skills, preschool children are attuned to FOP visuals while parents are able to use the visuals in combination with verbal claims to make food choices for their children. The purpose of this focus group study was to explore how parents of preschool children make sense of FOP visual and verbal claims on packaged food products that are intended for their children. Thematic analysis revealed that parents associated aspects that most appeal to their preschool children - the characters and other playful visuals - with higher sugar content and artificial ingredients. However, parents were also easily led to believe the product was healthier based on visuals of fruit, more realistic pictures, health claims, cross-branding with healthier foods, and visuals suggesting the product is more natural. While parents recognized that the health claims and some visuals may not truly mean the food is healthier, they agreed that they rarely think beyond their initial impression. The food industry needs better regulatory guidance on how to communicate flavors and ingredients on package fronts in a way that helps consumers - particularly parents wanting to encourage healthy eating habits for their young children - better match their nutrition goals.

    The reformulation of the food products available in the marketplace to improve their nutritional quality has been identified as one of the most cost-effective policies for controlling the global obesity pandemic. Front-of-pack (FOP) nutrition labelling is one of the strategies that has been suggested to encourage the food industry to reformulate their products. However, the extent to which certain FOP labels can encourage product reformulation is dependent on consumer reaction. The aim of the present work was to assess consumers' perception towards product reformulation in the context of the implementation of nutritional warnings, an interpretive FOP nutrition labelling scheme. Three product categories were selected as target products: bread, cream cheese and yogurt, each associated with high content of one target nutrient. For each category, six packages were designed using a 3 × 2 experimental design with the following variables: product version (regular, nutrient-reduced and nutrient-free) and brand (market leader and non-market leader). A total 306 Uruguayan participants completed a choice experiment with 18 choice sets. Reformulated products without nutritional warnings were preferred by participants compared to regular products with nutritional warnings. No apparent preference for products reformulated into nutrient-reduced or nutrient-free product versions was found, although differences depended on the product category and the specific reformulation strategy. Preference for reformulated products without nutritional warnings was more pronounced for non-market leaders. Results from the present work suggest that reformulation of foods in the context of the implementation of nutritional warnings holds potential to encourage consumers to make more healthful food choices and to cause a reduction of their intake of nutrients associated with non-communicable diseases.

    Objectives: The European Union (EU)-funded project Food Labelling to Advance Better Education for Life (FLABEL) aims to understand how nutrition information on food labels affects consumers' dietary choices and shopping behaviour. The first phase of this study consisted of assessing the penetration of nutrition labelling and related information on various food products in all 27 EU Member States and Turkey. Methods: In each country, food products were audited in three different types of retailers to cover as many different products as possible within five food and beverage categories: sweet biscuits, breakfast cereals, pre-packed chilled ready meals, carbonated soft drinks and yoghurts. Results: More than 37 000 products were audited in a total of 84 retail stores. On average, 85% of the products contained back-of-pack (BOP) nutrition labelling or related information (from 70% in Slovenia to 97% in Ireland), versus 48% for front-of-pack (FOP) information (from 24% in Turkey to 82% in the UK). The most widespread format was the BOP tabular or linear listing of nutrition content. Guideline daily amounts labelling was the most prevalent form of FOP information, showing an average penetration of 25% across all products audited. Among categories, breakfast cereals showed the highest penetration of nutrition-related information, with 94% BOP penetration and 70% FOP penetration. Conclusions: Nutrition labelling and related information was found on a large majority of products audited. These findings provide the basis for subsequent phases of FLABEL involving attention, reading, liking, understanding and use by consumers of different nutrition labelling formats. PMID:20808336

    To identify patterns of perception of front-of-pack (FOP) nutrition labels and to determine social factors, nutritional knowledge and attention to packaging features related to such patterns. Cross-sectional. Perception was measured using indicators of understanding and acceptability of three simple FOP labels (the 'Green Tick', the logo of the French Nutrition and Health Programme (PNNS logo) and 'simple traffic lights' (STL)) and two detailed formats ('multiple traffic lights' (MTL) and the 'colour range' logo (CR)). Associations of perception patterns with individual characteristics were examined using χ2 tests. Data from the French NutriNet-Santé cohort study. A total of 38,763 adults. Four perception patterns emerged. Poorly educated individuals were most often found in groups favouring simple formats. The 'favourable to CR' group had a high rate of men and older persons. Poor nutritional knowledge was more frequent in the 'favourable to STL' group, while individuals with substantial knowledge were proportionally more numerous in the 'favourable to MTL' group. The 'favourable to STL' group more frequently self-reported noting price and marketing characteristics during purchasing, while the 'favourable to MTL' and 'favourable to CR' groups declared more interest in nutritional information. The 'favourable to Green Tick and PNNS logo' group self-reported paying closer attention to claims and quality guarantee labels. The 'favourable to MTL' cluster was most frequently represented in our survey. However, simple FOP formats may be most appropriate for increasing awareness of healthy eating among targeted groups with poor nutritional knowledge and little interest in the nutritional quality of packaged foods.

  15. UK consumer perceptions of a novel till-receipt 'traffic-light' nutrition system.

    Cole, Matthew; Peek, Hayden; Cowen, Daniel

    2018-03-26

    Front-of-pack (FoP) traffic light nutrition labelling has been widely proposed as a tool to improve public health nutrition. Current evidence suggests that whilst consumers generally find them to be useful and an important source of information about a particular food or ingredient, this may have limited value in isolation when considering a person's overall nutritional intake. This study sought to examine UK consumers' use of existing FoP traffic light food labelling and ascertain public perception of a novel 'till-receipt' summary providing nutritional information about consumers entire shopping purchases. In total, 237 respondents completed an online questionnaire between May and June 2016. Almost two-thirds were female (n = 152, 64.1%) and the largest proportion of responses were received from those aged 25-32 years (n = 53, 22.4%) and 41-50 years (n = 53, 22.4%). About 83.5% of respondents suggested that they currently use traffic light information to inform their food purchases and 'health' was reported as the most important factor influencing food choice (42.2%; n = 100). Notably, 54.4% of respondents indicated that the novel till-receipt system could provide a solution to the potential limitations of existing FoP labelling and could help inform healthier food purchases. Our findings strengthen the existing evidence base to suggest that traffic light information is a useful tool to aid consumer food purchases. Moreover, our outcomes propose that consumers may benefit from a new receipt-based traffic light system which provides a more holistic summary of their entire food purchases.

    Front-of-pack (FOP) nutrition labelling has received growing attention from public health authorities, as a tool to promote healthier diets in the population. Recently, the French Health law introduced the principle of implementing a FOP nutrition labelling system. A scientific proposal has put forward the 5-Colour Nutrition Label (5-CNL), a five-category colour-coded summary system supported by research suggesting that it is well perceived and understood in the population. Our objective was to investigate the impact of the 5-CNL on the nutritional quality of purchases in experimental supermarkets. Participants (n = 901) were recruited using quota sampling between September and December 2015 and evenly distributed in three experimental conditions: 1) control situation; 2) Application of the 5-CNL on all food products in three specific sections: breakfast cereals, sweet biscuits and appetizers; 3) introduction of the 5-CNL accompanied by consumer information on use and understanding of the label. Main outcome was the nutritional quality of the shopping cart in the three sections combined, measured using the United Kingdom Food Standards Agency nutrient profiling system (FSA score). Significantly higher mean nutritional quality of the purchased items per section were observed for the sweet biscuits category in the intervention combining the label + communication (overall FSA score 21.01 vs. 20.23, P = 0.02). No significant effects were observed for the general mean over the three sections combined or other food categories. The results observed on purchase may be related to the high level of recall, self-reported and objective understanding of the label that were observed in the intervention groups as they are pre-requisites for use of a label in purchasing situations. These results suggest that the 5-CNL FOP nutrition label may have a limited impact on purchases, leading to healthier food choices in some food categories such as sweet biscuits. The trial

  1. A combination of transformation optics and surface impedance modulation to design compact retrodirective reflectors

    H. Haddad

    2018-02-01

    Full Text Available This study proposes a new approach to flatten retrodirective corner reflectors. The proposed method enables compact reflectors via Transformation Optics (TO combined with Surface Impedance Modulation (SIM. This combination permits to relax the constraints on the anisotropic material resulting from the TO. Phase gradient approach is generalized to be used within anisotropic media and is implemented with SIM. Different reflector setups are designed, simulated and compared for fop = 8GHz using ANSYS® HFSS® in order to validate the use of such a combination.

    In this paper, we propose a robust fractional-order proportional-integral U+0028 FOPI U+0029 observer for the synchronization of nonlinear fractional-order chaotic systems. The convergence of the observer is proved, and sufficient conditions are derived in terms of linear matrix inequalities U+0028 LMIs U+0029 approach by using an indirect Lyapunov method. The proposed U+0028 FOPI U+0029 observer is robust against Lipschitz additive nonlinear uncertainty. It is also compared to the fractional-order proportional U+0028 FOP U+0029 observer and its performance is illustrated through simulations done on the fractional-order chaotic Lorenz system.

  7. Application of Fuzzy Optimization to the Orienteering Problem

    Madhushi Verma

    2015-01-01

    Full Text Available This paper deals with the orienteering problem (OP which is a combination of two well-known problems (i.e., travelling salesman problem and the knapsack problem. OP is an NP-hard problem and is useful in appropriately modeling several challenging applications. As the parameters involved in these applications cannot be measured precisely, depicting them using crisp numbers is unrealistic. Further, the decision maker may be satisfied with graded satisfaction levels of solutions, which cannot be formulated using a crisp program. To deal with the above-stated two issues, we formulate the fuzzy orienteering problem (FOP and provide a method to solve it. Here we state the two necessary conditions of OP of maximizing the total collected score and minimizing the time taken to traverse a path (within the specified time bound as fuzzy goals and the remaining necessary conditions as crisp constraints. Using the max-min formulation of the fuzzy sets obtained from the fuzzy goals, we calculate the fuzzy decision sets (Z and Z∗ that contain the feasible paths and the desirable paths, respectively, along with the degrees to which they are acceptable. To efficiently solve large instances of FOP, we also present a parallel algorithm on CREW PRAM model.

  8. Nutrition marketing on processed food packages in Canada: 2010 Food Label Information Program.

    Schermel, Alyssa; Emrich, Teri E; Arcand, JoAnne; Wong, Christina L; L'Abbé, Mary R

    2013-06-01

    The current study describes the frequency of use of different forms of nutrition marketing in Canada and the nutrients and conditions that are the focus of nutrition marketing messages. Prepackaged foods with a Nutrition Facts table (N = 10,487) were collected between March 2010 and April 2011 from outlets of the 3 largest grocery chains in Canada and 1 major western Canadian grocery retailer. The nutrition marketing information collected included nutrient content claims, disease risk reduction claims, and front-of-pack nutrition rating systems (FOPS). We found that nutrition marketing was present on 48.1% of Canadian food packages, with nutrient content claims being the most common information (45.5%), followed by FOPS on 18.9% of packages. Disease risk reduction claims were made least frequently (1.7%). The marketing messages used most often related to total fat and trans fat (15.6% and 15.5% of nutrient content claims, respectively). Limiting total and trans fats is a current public health priority, as recommended by Health Canada and the World Health Organization. However, other nutrients that are also recommended to be limited, including saturated fats, sodium, and added sugars, were not nearly as prominent on food labels. Thus, greater emphasis should be placed by the food industry on these other important nutrients. Repeated data collection in the coming years will allow us to track longitudinal changes in nutrition marketing messages over time as food marketing, public health, and consumer priorities evolve.

    Full Text Available Fear of pain (FOP can increase risk for chronic pain and disability but little is known about corresponding neural responses in anticipation of potential pain. In this study, more (10 women, 6 men and less (7 women, 6 men pain-fearful groups underwent whole-brain functional magnetic resonance imaging (fMRI during anticipation of near pain-threshold stimulation. Groups did not differ in the proportion of stimuli judged to be painful but pain-fearful participants reported significantly more state fear prior to stimulus exposure. Within the entire sample, stronger activation was found in several pain regions (e.g., bilateral insula, midcingulate cortex (MCC, thalamus, superior frontal gyrus and visual areas linked to decoding stimulus valences (inferior orbital cortex during anticipation of painful stimuli. Between groups and correlation analyses indicated pain-fearful participants experienced comparatively more activity in regions implicated in evaluating potential threats and processing negative emotions during anticipation (i.e., MCC, mid occipital cortex, superior temporal pole, though group differences were not apparent in most so-called pain matrix regions. In sum, trait- and task-based FOP is associated with enhanced responsiveness in regions involved in threat processing and negative affect during anticipation of potentially painful stimulation.

    The morphological changes in 54 benign lung nodules, including 8 histologically proven nodules of tuberculoma, 10 of focal organizing pneumonia (FOP), 1 of lung abscess and 35 other benign nodules, were evaluated with contiguous thin-section (3 mm) CT. In addition, incremental dynamic studies were carried out in 25 of these nodules. The three-dimensional shapes of the nodules were found to be quite varied and were classified into four types: round mass (n=18), polygonal mass with concave or straight margins (n=20), oval or band-like mass extending along the bronchovascular bundle (n=7), and oval mass attached to the pleura with broad contact (n=9). Forty-two (78%) of the 54 nodules were located along the bronchovascular bundle. The maximum increments in CT values over 20 HU were observed after contrast enhancement in 18 (72%) of the 25 benign nodules, among which all tuberculomas showed little or no contrast enhancement. The number of small vessels quantified microscopically in the center of the nodules were minimal in tuberculomas with little enhancement and plentiful in lesions of FOP and abscess which showed marked enhancement. Our results suggest that the differentiation between benign and malignant pulmonary nodules is not possible simply on the basis of the degree of contrast enhancement. Therefore, morphological features and the anatomical relation to the bronchovascular bundles should also be taken into consideration in the diagnosis of pulmonary nodules. (author)

  13. The impact of price and nutrition labelling on sugary drink purchases: Results from an experimental marketplace study.

    Acton, Rachel B; Hammond, David

    2018-02-01

    To examine the effect of front-of-package (FOP) nutrition labelling and sugary drink taxation on consumer beverage purchases. A total of 675 respondents aged 16 years and older participated in an experimental marketplace study using a 4 × 5 within-between group design. Participants were randomised to one of four labelling conditions (no label; star rating; high sugar symbol; health warning) and completed five within-subject purchase tasks. Beverage prices in each task corresponded to 'tax' conditions: 0%, 10%, 20%, 30% and a variable tax proportional to free sugar level. In each task, participants selected from 20 commercially available beverages; upon conclusion, one of five selections was randomly chosen for purchase. As price increased, participants were significantly less likely to select a sugary drink, and selected drinks with fewer calories and less free sugar (p sugary drink (p = 0.11) and encouraging participants to select drinks with less free sugar (p = 0.11). Increasing price was associated with reduced sugary drink purchases. Enhanced FOP labelling results highlight the need for further research to investigate their potential impact. The study adds empirical support for taxation to reduce sugary drink consumption. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Conjoint analysis of orthodontic patients using the Subspinale (A-point) Nasion-Supramentale (B point) (ANB) angle and the Wits appraisal is popular in many practices. This study aimed to present reference values for the Wits appraisal among Nigerians using three horizontal reference planes namely the bisected occlusal plane (BOP), the functional occlusal plane (FOP) and the maxillomandibular angle bisector (MM° bisector) plane. It also assessed the relationship of the Wits appraisal with the ANB angle and its interaction with clinical measures of sagittal skeletal relations among subjects with malocclusion. One hundred participants with normal occlusion and 120 with malocclusion were recruited in the study. Cephalometric radiographs were taken for all participants. Each radiograph was manually traced on a 0.003 matted cellulose acetate tracing paper using a sharpened 2H pencil. The Wits appraisal and ANB angle were determined. Data was analyzed using SPSS version 19. The mean age was 20.7 ± 4.9 years for those with normal occlusion and 18.8 ± 6.5 years in the malocclusion group. There were 91 (41.4%) males and 129 (58.6%) females. Mean values for the Wits appraisal using the BOP as reference, was--1.27 ± 2.91mm, with the FOP, it was -3.54 ± 3.24mm, while with the MM° bisector plane, it was--.75? ± .94mm. The ANB angle showed highest correlation with the MM'°bisector plane Wits value(Pplane Wits appraisal.

  15. Nutrition warnings as front-of-pack labels: influence of design features on healthfulness perception and attentional capture.

    Cabrera, Manuel; Machín, Leandro; Arrúa, Alejandra; Antúnez, Lucía; Curutchet, María Rosa; Giménez, Ana; Ares, Gastón

    2017-12-01

    Warnings are a new directive front-of-pack (FOP) nutrition labelling scheme that highlights products with high content of key nutrients. The design of warnings influences their ability to catch consumers' attention and to clearly communicate their intended meaning, which are key determinants of their effectiveness. The aim of the present work was to evaluate the influence of design features of warnings as a FOP nutrition labelling scheme on perceived healthfulness and attentional capture. Five studies with a total of 496 people were carried out. In the first study, the association of colour and perceived healthfulness was evaluated in an online survey in which participants had to rate their perceived healthfulness of eight colours. In the second study, the influence of colour, shape and textual information on perceived healthfulness was evaluated using choice-conjoint analysis. The third study focused on implicit associations between two design features (shape and colour) on perceived healthfulness. The fourth and fifth studies used visual search to evaluate the influence of colour, size and position of the warnings on attentional capture. Perceived healthfulness was significantly influenced by shape, colour and textual information. Colour was the variable with the largest contribution to perceived healthfulness. Colour, size and position of the warnings on the labels affected attentional capture. Results from the experiments provide recommendations for the design of warnings to identify products with unfavourable nutrient profile.

  16. Testing consumer perception of nutrient content claims using conjoint analysis.

    2010-05-01

    The US Food and Drug Administration (FDA) proposes to establish standardized and mandatory criteria upon which front-of-pack (FOP) nutrition labelling must be based. The present study aimed to estimate the relative contribution of declared amounts of different nutrients to the perception of the overall 'healthfulness' of foods by the consumer. Protein, fibre, vitamin A, vitamin C, calcium and iron were nutrients to encourage. Total fat, saturated fat, cholesterol, total and added sugar, and sodium were the nutrients to limit. Two content claims per nutrient used the FDA-approved language. An online consumer panel (n 320) exposed to multiple messages (n 48) rated the healthfulness of each hypothetical food product. Utility functions were constructed using conjoint analysis, based on multiple logistic regression and maximum likelihood estimation. Consumer perception of healthfulness was most strongly driven by the declared presence of protein, fibre, calcium and vitamin C and by the declared total absence of saturated fat and sodium. For this adult panel, total and added sugar had lower utilities and contributed less to the perception of healthfulness. There were major differences between women and men. Conjoint analysis can lead to a better understanding of how consumers process information about the full nutrition profile of a product, and is a powerful tool for the testing of nutrient content claims. Such studies can help the FDA develop science-based criteria for nutrient profiling that underlies FOP and shelf labelling.

  17. Physical and Chemical Barriers in Root Tissues Contribute to Quantitative Resistance to Fusarium oxysporum f. sp. pisi in Pea

    Moustafa Bani

    2018-02-01

    Full Text Available Fusarium wilt caused by Fusarium oxysporum f. sp. pisi (Fop is one of the most destructive diseases of pea worldwide. Control of this disease is difficult and it is mainly based on the use of resistant cultivars. While monogenic resistance has been successfully used in the field, it is at risk of breakdown by the constant evolution of the pathogen. New sources of quantitative resistance have been recently identified from a wild relative Pisum spp. collection. Here, we characterize histologically the resistance mechanisms occurring in these sources of quantitative resistance. Detailed comparison, of the reaction at cellular level, of eight pea accessions with differential responses to Fop race 2, showed that resistant accessions established several barriers at the epidermis, exodermis, cortex, endodermis and vascular stele efficiently impeding fungal progression. The main components of these different barriers were carbohydrates and phenolic compounds including lignin. We found that these barriers were mainly based on three defense mechanisms including cell wall strengthening, formation of papilla-like structures at penetration sites and accumulation of different substances within and between cells. These defense reactions varied in intensity and localization between resistant accessions. Our results also clarify some steps of the infection process of F. oxysporum in plant and support the important role of cell wall-degrading enzymes in F. oxysporum pathogenicity.

    Full Text Available A esclerose múltipla é uma afecção neurológica que envolve distúrbios da deglutição. Muitos estudos têm mostrado associação entre o comprometimento neurológico e o desempenho da deglutição, porém, os resultados têm sido conflitantes. OBJETIVO: Identificar a frequência de disfagia nos pacientes com esclerose múltipla e os indicadores neurológicos que podem representar o desempenho da deglutição. MÉTODO: Neste estudo (estudo transversal, 120 pacientes com esclerose múltipla foram submetidos à avaliação funcional da deglutição por fibronasofaringolaringoscopia, cujos resultados foram comparados com a pontuação das escalas de classificação (Formas Clínicas Evolutivas da Doença, Escala de Incapacidade Funcional por Sistemas e Escala Ampliada de Incapacidade Funcional [Kurtzke Expanded Disability Status Scale]. RESULTADOS: A disfagia foi identificada em 90% dos pacientes. Dentre as formas clínicas, as formas progressivas (primária progressiva e secundária progressiva apresentaram com maior frequência disfagia grave, enquanto a forma remitente-recorrente apresentou mais frequentemente disfagia leve e moderada. Em relação à Escala de Incapacidade Funcional por Sistemas, as funções cerebelares, do tronco encefálico e mental tiveram associação com a disfagia, especialmente na forma grave. Quanto à Escala Ampliada de Incapacidade Funcional, pontuações mais altas se associaram aos quadros graves de disfagia. CONCLUSÃO: A disfagia é frequente em pacientes com esclerose múltipla, especialmente naqueles com maior comprometimento das funções neurológicas.

  19. Malignant fibrous histiocytoma of soft tissue with metaplastic bone and cartilage formation

    Dorfman, H.D.; Bhagavan, B.S.

    1982-01-01

    The presence of bone and cartilage in some cases of malignant fibrous histiocytoma of the soft tissue as a microscopic finding has been reported previously but little note has been taken of the radiologic manifestations of these tumor elements. A series of five such cases with sufficient metaplastic osseous and cartilaginous elements to produce roentgenographic evidence of their presence is reported here. An additional two cases showed only histologic evidence of bone or cartilage formation. The reactive ossification tends to be peripheral in location, involving the pseudocapsule of the sarcoma or its fibrous septa. In three there was a zoning pattern with peripheral or polar orientation, strongly suggesting the diagnosis of myositis ossificans. The latter was the diagnosis considered radiologically in four of the five cases. Malignant fibrous histiocytoma with reactive bone and cartilage must be considered in the differential diagnosis of soft tissue masses with calcific densities, particularly when these occur in tumors of the extremities.

  20. Histology and imaging of soft tissue sarcomas.

    Kind, Michèle; Stock, Nathalie; Coindre, Jean Michel

    2009-10-01

    Imaging and histology are two complementary morphological techniques which play a fundamental role in the diagnosis and management of soft tissue sarcomas. Imaging allows to identify some pseudosarcomatous benign lesions such as myositis ossificans, intramuscular hemangioma, angiomyolipoma, intramuscular lipoma, giant cell tumour of tendon sheath, desmoid tumour and elastofibroma. There is no formal criterion for diagnosing a sarcoma on magnetic resonance imaging (MRI) but malignancy is strongly suspected with the presence of necrosis and vascular, bone or joint invasion. Imaging may also suggest some histological types of sarcoma such as well-differentiated liposarcoma, dedifferentiated liposarcoma, synovial sarcoma or extraskeletal osteosarcoma. Imaging is also extremely helpful in determining the appropriate kind of sampling to carry out and in guiding the performance of a microbiopsy. The appearance observed on imaging should always be taken into consideration for the interpretation of the microbiopsy by the pathologist.

    2010-01-01

    Radial neck fractures are a common injury in children as a result of a fall on an extended and supinated outstretched hand. We present 2 cases of osteotomy of the neck of the radius performed in 2 children with neglected radial neck fractures. Preoperatively, both patients complained of pain and severely reduced mobility of the elbow. Surgery was performed at 6 weeks and 3 months, respectively, after the initial injury and the 2 children were reviewed at 6 and 16 months follow-up. Osteotomies healed within the usual time and no avascular necrosis of the radial head, proximal radioulnar synostosis, or myositis ossificans were observed. The Mayo Elbow Performance Index Score improved significantly after the operation with the 2 patients rated as excellent. In this small series, we present a novel technique of proximal osteotomy of the radius to correct this deformity in children. Case series, level IV evidence.

    Aneurysmal bone cyst (ABC) is an expansile cystic lesion that may affect any bone of the skeleton. Although exceedingly rare, lesions with histomorphologic characteristics of an ABC have reportedly originated within soft tissue. Extraskeletal ABC may mimic a variety of benign and malignant lesions and can be confused with other more common or rare giant cell-rich tumors of soft tissue, especially myositis ossificans. Clinical, radiological and histologic correlation is crucial in reaching the correct diagnosis. Cytogenetic and/or molecular genetic analysis is a useful adjunct in diagnosing these exquisitely rare lesions. Here we report a case of an ABC arising in an extraskeletal site and provide a comprehensive review of literature on this rare entity. Copyright © 2017 Elsevier GmbH. All rights reserved.

    Cochlear implant is the method of choice in the treatment of deep sensorineural hypoacusis, particularly in patients where conventional amplification devices do not imply noticeable clinical improvement. Imaging findings are crucial in the indication or contraindication for such surgical procedure. In the assessment of the temporal bone, radiologists should be familiar with relative or absolute contraindication factors, as well as with factors that might significantly complicate the implantation. Some criteria such as cochlear nerve aplasia, labyrinthine and/or cochlear aplasia are still considered as absolute contraindications, in spite of studies bringing such criteria into question. Cochlear dysplasias constitute relative contraindications, among them labyrinthitis ossificans is highlighted. Other alterations may be mentioned as complicating agents in the temporal bone assessment, namely, hypoplasia of the mastoid process, aberrant facial nerve, otomastoiditis, otosclerosis, dehiscent jugular bulb, enlarged endolymphatic duct and sac. The experienced radiologist assumes an important role in the evaluation of this condition. (author)

  5. Musculoskeletal disorders associated with HIV infection and AIDS. Part II: Non-infectious musculoskeletal conditions

    Tehranzadeh, Jamshid; Ter-Oganesyan, Ramon R.; Steinbach, Lynne S.

    2004-01-01

    This section of a two-part series on musculoskeletal disorders associated with HIV infection and AIDS reviews the non-infectious musculoskeletal conditions. In the first part, the infectious conditions were reviewed. The non-infectious conditions include polymyositis, drug-induced myopathy, myositis ossificans, adhesive capsulitis, avascular necrosis, bone marrow abnormalities, and hypertrophic osteoarthropathy. Inflammatory and reactive arthropathies are more prevalent in HIV-positive individuals, and a separate section is dedicated to these conditions, including Reiter's syndrome, psoriatic arthritis, HIV-associated arthritis, painful articular syndrome, and acute symmetric polyarthritis. Lastly, we include a discussion of HIV-related neoplastic processes that affect the musculoskeletal system, namely Kaposi's sarcoma and non-Hodgkin's lymphoma. (orig.)

    Imaging and histology are two complementary morphological techniques which play a fundamental role in the diagnosis and management of soft tissue sarcomas. Imaging allows to identify some pseudosarcomatous benign lesions such as myositis ossificans, intramuscular hemangioma, angiomyolipoma, intramuscular lipoma, giant cell tumour of tendon sheath, desmoid tumour and elastofibroma. There is no formal criterion for diagnosing a sarcoma on magnetic resonance imaging (MRI) but malignancy is strongly suspected with the presence of necrosis and vascular, bone or joint invasion. Imaging may also suggest some histological types of sarcoma such as well-differentiated liposarcoma, dedifferentiated liposarcoma, synovial sarcoma or extraskeletal osteosarcoma. Imaging is also extremely helpful in determining the appropriate kind of sampling to carry out and in guiding the performance of a microbiopsy. The appearance observed on imaging should always be taken into consideration for the interpretation of the microbiopsy by the pathologist.

    To evaluate MR findings of soft tissue masses in extremities and to find the helpful findings of distinguish benignity from malignancy, 28 soft tissue masses (22 benign and 6 malignant) in extremities were reviewed. TI-weighted, proton density, T2-weighted and Gd-DTPA enhanced images were obtained. MR images allowed a specific diagnosis in large number of benign masses, such as hemangioma(8/9), lipoma(2/2), angiolipoma(1/1), epidermoid cyst(2/2), myositis ossificans(1/1), synovial chondromatosis(1/1) and pigmented villonodular synovitis(1/2). Specific diagnosis was difficult in the rest of the masses including malignancy. However, inhomogeneous signal intensities with necrosis and inhomogeneous enhancement may suggest malignant masses.

  8. Benign bone-forming lesions: osteoma, osteoid osteoma, and osteoblastoma; Clinical, imaging, pathologic, and differential considerations

    The benign bone lesions - osteoma, osteoid osteoma, and osteoblastoma - are characterized as bone-forming because tumor cells produce osteoid or mature bone. Osteoma is a slow-growing lesion most commonly seen in the paranasal sinuses and in the calvaria. When it occurs in the long bones, it is invariably juxtacortical and may need to be differentiated from, among others, parosteal osteosarcoma, sessile osteochondroma, and a matured juxtacortical focus of myositis ossificans. Osteoid osteoma and osteoblastoma appear histologically very similar. Their clinical presentations and distribution in the skeleton, however, are distinct: osteoid osteoma is usually accompanied by nocturnal pain promptly relieved by salicylates; osteoblastoma arises predominantly in the axial skeleton, spinal lesions constituting one-third of reported cases. This review focuses on the application of the various imaging modalities in the diagnosis, differential diagnosis, and evaluation of these lesions. Their histopathology also is discussed, and their treatment briefly outlined. (orig.)

    The case of a 35-year-old woman with low-grade extraskeletal osteosarcoma of the left leg is presented. Radiographs showed peripheral ossification of the lesion, suggesting myositis ossificans. Most of the tumor was composed of cartilage, and the cellularity and cell atypia of the proliferating chondrocytes were mild to moderate. In the periphery, bone formation with a relatively clear margin and proliferation of spindle cells with minimal nuclear atypia were observed. The average percentage of cells positive for MIB-1 was 9.0%. A diagnosis of low-grade extraskeletal osteosarcoma was made on the basis of these histologic findings. The clinical course 47 months after a wide excision was uneventful. (orig.)

    1990-01-01

    The purpose of this study was to assess the diagnostic and differential diagnostic value of high-resolution computed tomography in the evaluation of temporal-bone dystrophies. The study group included 55 patients with osseous abnormalities of the temporal bone in general, and the labyrinthine capsule in particular. In 27 patients the CT scan revealed evidence of otodystrophic lesions. The CT findings in patients with otosclerosis (21 patients), osteogenesis imperfecta (two patients), fibrous dysplasia (one patient). Paget's disease (one patient) and osteoporosis (two patients) are described. The CT scans of 17 patients revealed secondary osseous lesions due to metastasis (five patients), post-inflammatory changes (10 patients) or labyrinthitis ossificans (two patients). Normal variants and congenital mineralization defects were diagnosed in nine patients, Down's syndrome in two. Our results indicate the importance of high-resolution computed tomography as the primary imaging modality in evaluating osseous lesions of the temporal bone and labyrinth.

  15. Angiography of primary bone tumors

    Keyl, W.; Kunkel, B.

    1982-01-01

    To determine the type of a tumour by means of angiography is problematical. Considering that tumour-simulating lesions (myositis ossificans, modular synoritis) can also show pathological blood vessel formations and AV-shunts the interpretation of vessel-architectonic criteria must be done very carefully. The finding of some individual signs of malignancy does not justify the diagnosis of ''malignant tumour''. Only the ''anarchic vessel picture'' (Freyschmidt) with changing caliber, corkscrew vessels, interrupted vessels, unregular tumour colouring, arteria-venous shunts and possibly also tumour invasion into vessels makes a malignant process very likely. The absence of these criteria, however, does not exclude malignancy. Non-vascularised malignant tumours can only lead to a displacement of vessels without an angiographic proof of the tumour itself.

  16. Extraosseous localization of sup(99m)Tc-diphosphonate

    Nakama, M; Sugawara, T; Furuse, M; Shibuya, K; Watanabe, T [Jichi Medical School, Tochigi (Japan)

    1977-10-01

    Many different types of extraosseous lesions have been reported using /sup 99m/Tc-phosphate bone scanning agents. Abnormal extraosseous localization was observed in 30 cases among the patients referred for bone scanning with /sup 99/Tc-diphosphonate. The lesions associated with extraosseous accumulation are as follows: carcinomatous pleurisy 14 cases; lung cancer 3; brain metastasis 3; digestive tract cancer 4; skin and contralateral breast metastasis from breast cancer 1; respectively; and other benign disease 4, e.i. meningioma, angiofibroma of the nasopharynx, and myositis ossificans. Eighty-seven per cent of the extra-osseous accumulations of /sup 99m/Tc-diphosphonate were malignant, and preferential accumulation for adenocarcinoma was observed in comparison with other pathological groups. Among those patients, 7 cases of marked extraosseous localizations were demonstrated in this report. The mechanisms for the localization in extraosseous lesions are discussed.

  17. Computerized tomography of pelvic osteomyelitis in patients with spinal cord injuries

    Firooznia, H.; Rafii, M.; Golimbu, C.; Sokolow, J.

    1983-01-01

    Computerized tomography (CT) was performed in 19 patients with spinal cord injury (SCI) who had large pressure sores and in whom other complications were suspected. CT detected the depth, extent, and degree of undermining of the edges of the pressure sores in 19 of 27 lesions. Conventional radiography detected four cases of pelvic osteomyelitis. CT detected eight additional cases of pelvic osteomyelitis, as well as eight clinically unsuspected peripelvic and intrapelvic abscesses. Technetium-99m bone scanning was not very helpful because of localization in chronic proliferative changes of bone and widespread foci of myositis ossificans, as well as in osteomyelitis. Gallium-67 scanning detected only one of six abscesses. It was not very helpful because of confusion of abscess and osteomyelitis with intense soft tissue swelling and cellulitis, which are often associated with pressure sores in patients with chronic SCI. CT was found to be, by far, the modality of choice for detection of pelvic osteomyelitis and abscess in patients with SCI

    Full Text Available Observações sobre a epizootiologia da "cara inchada" dos bovinos (CI indicam que animais clinicamente positivos se recuperam espontâneamente quando transferidos para área indene. No presente estudo, 13 bovinos com lesões peridentárias progressivas da "cara inchada" foram transferidos para área indene com a finalidade de se verificar a evolução clínica da doença e a composição da microbiota da bolsa peridentária em duas situações distintas: (1 nas lesões progressivas e (2 quando da recuperação clínica. O estudo bacteriológico semi-quantitativo e qualitativo foi realizado tendo como referência a percentagem de Bacteroides pigmentados de negro presentes nos cultivos. Nas lesões progressivas a percentagem média destes microrganismos foi de 71,3%. Após 4 a 7 meses da transferência os animais se recuperaram espontaneamente, observando-se uma melhora na condição nutricional, desaparecimento do abaulamento facial e do odor fétido bucal e cicatrização com epitelização das lesões peridentárias. Na avaliação da composição da micro-biota das bolsas peridentárias dos bezerros quando clinicamente recuperados, este mesmo grupo de micorganismos representou em média 1,7%. Os resultados revelaram a ocorrência de uma predominância de Bacteroides pigmentados de negro nas lesões peridentárias progressivas da "cara inchada"e sua remissão quantitativa percentual após a recuperação clínica dos animais, consubstanciando as evidências de sua natureza infecciosa primária.

    Mabel Franzone

    2005-03-01

    Full Text Available Attraverso due racconti di Cortázar, l'analisi di due figure del desiderio ci permette esplorare due estremi seguendo una verticalità. La distruzione, doppio tenebroso della nostra anima, ci rivela un erotismo legato alla morte e al desiderio morboso di possedere l'Altro; il suo contraltare è un'ascesa vertiginosa accompagnata da un godimento estetico, dall'amore sublime prossimo all'esperienza mistica che si concluderà con una discesa progressiva e nel rispetto di questo Altro. La creazione letteraria si presenta come uno sfogo alle nostre angosce, che sono anche una sorta d'espressione dell'erotismo.

    MRI has gained an undisputed place in the evaluation of malignant bone tumors, not only for verifying results of conventional radiography and clarifying differential diagnoses; it has also become increasingly important for the assessment of the malignant/benign nature of the tumor, its growth rate, definition of adequate sites for biopsy, local preoperative staging, and evaluation of the response to chemotherapy. However, several pitfalls have to be observed regarding choice of technical parameters (coils, sequences, imaging planes), tissue differentiation, and tumor staging. When staging malignant tumors, critical aspects which have to be observed are tumor extension, integrity of the cortical bone, soft tissue components, infiltration of a joint or neurovascular bundle. The use of contrast agents provides important additional information but can also give rise to misinterpretations. Thus, all features of a tumor have to be observed in order to establish a final diagnosis. Particular difficulties can occur with the interpretation of MR images of osteomyelitis, osteoid osteoma, stress and insufficiency fractures, bone infarcts, myositis ossificans, hemangiomas, and aneurysmal bone cysts. (orig.) [Deutsch] Bei der Diagnostik von malignen Knochentumoren hat die MRT einen fixen Platz nicht nur in der Verifikation der Nativdiagnostik und der Differentialdiagnostik, sondern zunehmende Bedeutung bei der primaeren Beurteilung von Dignitaet und Wachstumsgeschwindigkeit, Definition einer geeigneten Biopsiestelle, beim lokoregionaeren, praeoperativen Staging und der Evaluation des Ansprechens auf Chemotherapie. Zahlreiche Pitfalls finden sich jedoch bei der Wahl der technischen Parameter (Spulen, Sequenzen, Schichtebenen), der Tumordifferenzierung und beim Staging von malignen Tumoren. Beim Staging sind die kritischen Punkte die Beurteilung von Tumorausdehnung, Integritaet der Kortikalis, Vorhandensein einer Weichteilkomponente, Infiltration eines Gelenks oder des

    Since musculoskeletal tumours comprise a large heterogeneous group of entities with different biological behaviour, clinical diagnosis of such lesions can be very difficult. The aim of this prospective study was to assess the usefulness of 2-[F-18]-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography (PET) in the non-invasive evaluation of soft tissue tumours. One hundred and two patients with suspected soft tissue neoplasms were investigated by FDG-PET. The uptake of FDG was evaluated semiquantitatively by determining the tumour to background ratio (TBR). All patients underwent biopsy, resulting in the histological detection of 39 high-grade sarcomas, 16 intermediate-grade sarcomas, 11 low-grade sarcomas, 25 benign tumours, 10 tumour-like lesions such as spontaneous myositis ossificans (n = 6) and one non-Hodgkin lymphoma. All lesions except for two lipomas disclosed an increased FDG uptake. Sarcomas showed significantly higher TBR values than latent or active benign lesions (P<0.001) and aggressive benign lesions (P<0.05). Using a TBR cut-off level of 3.0 for malignancy, sensitivity of FDG-PET was 97.0%, specificity 65.7% and accuracy 86.3%. From our data there are three main conclusions: (1) Except for patients with pseudotumoral myositis ossificans, lesions with a TBR >3 were sarcomas (91.7%) or aggressive benign tumours (8.3%). (2) Tumours with a TBR <1.5 were latent or active benign lesions, exclusively. (3) The group with intermediate TBR values (<3 and >1.5) comprised primarily latent or active benign lesions, but also four aggressive benign tumours and two low-grade sarcomas. Our data suggest that FDG-PET represents a useful tool for the evaluation of the biological activity of soft tissue neoplasms. (orig.) With 5 figs., 2 tabs., 26 refs.

    Full Text Available We report the case of a patient with trisomy 21 (T21 with late onset epilepsy. The electro-clinical features were of myoclonic jerks on awakening and generalised tonic clonic seizures, with generalised spike and wave on EEG, and a progressive dementia. As familial Alzheimer's dementia and progressive myoclonic epilepsy (Unverricht-Lundborg type are both linked to the chromosome 21, this case may represent a distinct progressive myoclonic epilepsy related to T21.Pacientes com trissomia do cromossoma 21 (T21, com o passar dos anos, são propensos a desenvolver crises epilépticas parciais concomitantes ao aparecimento de degeneração cerebral do tipo Alzheimer. Pacientes com T21 e demência parecem ter risco maior de apresentarem crises epilépticas que outros pacientes com degeneração cerebral do tipo Alzheimer. O caso relatado é de um paciente com T21 com epilepsia de início tardio. A história clínica consiste de crises mioclônicas ao despertar, ocasionais crises generalizadas tônico-clônicas, demência e ponta onda generalisada no EEG. Demência do tipo Alzheimer familial é ligada ao cromossoma 21, bem como epilepsia mioclônica progressiva (tipo Unverricht-Lundborg. Isto sugere que este caso possa representar um tipo distinto de epilepsia mioclônica progressiva, ligado ao cromossoma 21.

    2013-09-01

    Full Text Available Este trabalho calcula as características distributivas dos bens e serviços consumidos pelas famílias no Brasil, usando a POF 2008-2009, e utiliza essa informação para elaborar propostas alternativas de reforma tributária indireta. O impacto das reformas sobre o bem-estar é avaliado usando o conceito de "variação equivalente" e o sistema de demanda quase ideal na forma quadrática (QUAIDS. Os resultados mostram que os três itens de consumo familiar com características distributivas mais elevadas são combustível doméstico, fumo e cesta básica de alimentos, e os três itens com características distributivas mais baixas são combustível automotivo, bebidas alcoólicas e transporte privado. As reformas baseadas nas características distributivas são progressivas, sendo que a mais progressiva resulta em um aumento de bem-estar das famílias mais pobres equivalente a um aumento de 8,2% no seu consumo, e em uma perda de bem-estar para as famílias mais ricas equivalente a uma redução de 5,6% no seu consumo.

    2018-01-01

    We describe the search for TESS Objects of Interest (TOIs), led by the MIT branch of the TESS Science Office (TSO). TSO has developed a tool called TESS Exoplanet Vetter (TEV) to facilitate this process. Individuals independently examine data validation products for each target and assign a category to the object: planet candidate, eclipsing binary, other astrophysical, stellar variability, or instrument noise/systematic. TEV assigns a preliminary follow-up priority designation to each object and allows for modification when final dispositions are decided on in a group setting. When all targets are vetted, TEV exports a catalogue of TOIs which is delivered to the TESS Follow-Up Observing Program (TFOP), working with ExoFOP-TESS, and made publicly available on the official TESS website and the Mikulski Archive for Space Telescopes (MAST).

    Full Text Available The article reviews the capabilities and particularities of the approach to the improvement of metrological characteristics of fiber-optic pressure sensors (FOPS based on estimation estimation of dynamic errors in laser optoelectronic dimension gauges for geometric measurement of details. It is shown that the proposed criteria render new methods for conjugation of optoelectronic converters in the dimension gauge for geometric measurements in order to reduce the speed and volume requirements for the Random Access Memory (RAM of the video controller which process the signal. It is found that the lower relative error, the higher the interrogetion speed of the CCD array. It is shown that thus, the maximum achievable dynamic accuracy characteristics of the optoelectronic gauge are determined by the following conditions: the parameter stability of the electronic circuits in the CCD array and the microprocessor calculator; linearity of characteristics; error dynamics and noise in all electronic circuits of the CCD array and microprocessor calculator.

    Front-of-pack (FOP) nutrition labelling has received extensive political attention in recent years. Most studies assessing the influence of nutrition labelling focus on consumer attention to labels, while few concentrate on its effects on actual purchase behaviour. In this study, we present results...... to enable us to identify as many influencing factors on food choice as possible. We utilize the SSAg/1 health score for our food categories as a dependent variable to obtain an objective measure of healthiness. Our results suggest that the GDA label introduction reduces attraction of unhealthier products...... in terms of market share but does not affect product choice behaviour. Instead, price and habit exhibit a greater impact on purchase behaviour and product choice than the GDA label introduction....

    Rajalakshmi, Ramachandran; Subashini, Radhakrishnan; Anjana, Ranjit Mohan; Mohan, Viswanathan

    2018-06-01

    To assess the role of artificial intelligence (AI)-based automated software for detection of diabetic retinopathy (DR) and sight-threatening DR (STDR) by fundus photography taken using a smartphone-based device and validate it against ophthalmologist's grading. Three hundred and one patients with type 2 diabetes underwent retinal photography with Remidio 'Fundus on phone' (FOP), a smartphone-based device, at a tertiary care diabetes centre in India. Grading of DR was performed by the ophthalmologists using International Clinical DR (ICDR) classification scale. STDR was defined by the presence of severe non-proliferative DR, proliferative DR or diabetic macular oedema (DME). The retinal photographs were graded using a validated AI DR screening software (EyeArt TM ) designed to identify DR, referable DR (moderate non-proliferative DR or worse and/or DME) or STDR. The sensitivity and specificity of automated grading were assessed and validated against the ophthalmologists' grading. Retinal images of 296 patients were graded. DR was detected by the ophthalmologists in 191 (64.5%) and by the AI software in 203 (68.6%) patients while STDR was detected in 112 (37.8%) and 146 (49.3%) patients, respectively. The AI software showed 95.8% (95% CI 92.9-98.7) sensitivity and 80.2% (95% CI 72.6-87.8) specificity for detecting any DR and 99.1% (95% CI 95.1-99.9) sensitivity and 80.4% (95% CI 73.9-85.9) specificity in detecting STDR with a kappa agreement of k = 0.78 (p < 0.001) and k = 0.75 (p < 0.001), respectively. Automated AI analysis of FOP smartphone retinal imaging has very high sensitivity for detecting DR and STDR and thus can be an initial tool for mass retinal screening in people with diabetes.

    Interpretive, front-of-pack (FOP) nutrition labels may encourage reformulation of packaged foods. We aimed to evaluate the effects of the Health Star Rating (HSR), a new voluntary interpretive FOP labelling system, on food reformulation in New Zealand. Annual surveys of packaged food and beverage labelling and composition were undertaken in supermarkets before and after adoption of HSR i.e., 2014 to 2016. Outcomes assessed were HSR uptake by food group star ratings of products displaying a HSR label; nutritional composition of products displaying HSR compared with non-HSR products; and the composition of products displaying HSR labels in 2016 compared with their composition prior to introduction of HSR. In 2016, two years after adoption of the voluntary system, 5.3% of packaged food and beverage products surveyed ( n = 807/15,357) displayed HSR labels. The highest rates of uptake were for cereals, convenience foods, packaged fruit and vegetables, sauces and spreads, and 'Other' products (predominantly breakfast beverages). Products displaying HSR labels had higher energy density but had significantly lower mean saturated fat, total sugar and sodium, and higher fibre, contents than non-HSR products (all p -values labelled products compared with their composition prior to adoption of HSR. Reformulation of HSR-labelled products was greater than that of non-HSR-labelled products over the same period, e.g., energy reduction in HSR products was greater than in non-HSR products (-1.5% versus -0.4%), and sodium content of HSR products decreased by 4.6% while that of non-HSR products increased by 3.1%. We conclude that roll-out of the voluntary HSR labelling system is driving healthier reformulation of some products. Greater uptake across the full food supply should improve population diets.

    2012-02-01

    The 'Smart Choices' programme was an industry-driven, front-of-package (FOP) nutritional labelling system introduced in the USA in August 2009, ostensibly to help consumers select healthier options during food shopping. Its nutritional criteria were developed by members of the food industry in collaboration with nutrition and public health experts and government officials. The aim of the present study was to test the extent to which products labelled as 'Smart Choices' could be classified as healthy choices on the basis of the Nutrient Profile Model (NPM), a non-industry-developed, validated nutritional standard. A total of 100 packaged products that qualified for a 'Smart Choices' designation were sampled from eight food and beverage categories. All products were evaluated using the NPM method. In all, 64 % of the products deemed 'Smart Choices' did not meet the NPM standard for a healthy product. Within each 'Smart Choices' category, 0 % of condiments, 8·70 % of fats and oils, 15·63 % of cereals and 31·58 % of snacks and sweets met NPM thresholds. All sampled soups, beverages, desserts and grains deemed 'Smart Choices' were considered healthy according to the NPM standard. The 'Smart Choices' programme is an example of industries' attempts at self-regulation. More than 60 % of foods that received the 'Smart Choices' label did not meet standard nutritional criteria for a 'healthy' food choice, suggesting that industries' involvement in designing labelling systems should be scrutinized. The NPM system may be a good option as the basis for establishing FOP labelling criteria, although more comparisons with other systems are needed.

  9. New Developments At The Science Archives Of The NASA Exoplanet Science Institute

    Berriman, G. Bruce

    2018-06-01

    The NASA Exoplanet Science Institute (NExScI) at Caltech/IPAC is the science center for NASA's Exoplanet Exploration Program and as such, NExScI operates three scientific archives: the NASA Exoplanet Archive (NEA) and Exoplanet Follow-up Observation Program Website (ExoFOP), and the Keck Observatory Archive (KOA).The NASA Exoplanet Archive supports research and mission planning by the exoplanet community by operating a service that provides confirmed and candidate planets, numerous project and contributed data sets and integrated analysis tools. The ExoFOP provides an environment for exoplanet observers to share and exchange data, observing notes, and information regarding the Kepler, K2, and TESS candidates. KOA serves all raw science and calibration observations acquired by all active and decommissioned instruments at the W. M. Keck Observatory, as well as reduced data sets contributed by Keck observers.In the coming years, the NExScI archives will support a series of major endeavours allowing flexible, interactive analysis of the data available at the archives. These endeavours exploit a common infrastructure based upon modern interfaces such as JuypterLab and Python. The first service will enable reduction and analysis of precision radial velocity data from the HIRES Keck instrument. The Exoplanet Archive is developing a JuypterLab environment based on the HIRES PRV interactive environment. Additionally, KOA is supporting an Observatory initiative to develop modern, Python based pipelines, and as part of this work, it has delivered a NIRSPEC reduction pipeline. The ensemble of pipelines will be accessible through the same environments.

  10. Association between a dietary quality index based on the food standard agency nutrient profiling system and cardiovascular disease risk among French adults.

    In France, the implementation of a front-of-pack (FOP) nutrition label-the 5-Colour Nutrition Label (5-CNL) is currently under consideration as a strategic tool to allow consumers making healthier food choices. This FOP label is based on the British Food Standards Agency Nutrient Profiling System (FSA-NPS), reflecting the overall nutritional quality of foods. At the individual level, an energy-weighted mean of all FSA-NPS scores of foods usually consumed has been elaborated (FSA-NPS DI). Our objective was to investigate the prospective association between the FSA-NPS DI and cardiovascular disease (CVD) risk. 75,801 participants to the NutriNet-Santé cohort, who completed at least three 24h dietary records during the first 2y of the follow-up, were followed between 2009 and 2016. Multivariable Cox proportional hazards models were used to characterize the associations between FSA-NPS DI and the incidence of CVDs. 509 major cardiovascular events were diagnosed (262 coronary heart diseases and 247 strokes). A higher FSA-NPS DI, characterizing lower dietary quality, was associated with increased CVD risk (HR for a 1-point increment =1.08 (1.03-1.13); HR Q4vs.Q1 =1.40 (1.06-1.84), P trend Q4-Q1 =0.01). This association tended to be stronger in overweight subjects (HR for a 1-point increment =1.12 (1.04-1.19); P interaction =0.003). These results suggest that lower dietary quality, as reflected by a higher FSA-NPS DI, may be associated with a significant increase in cardiovascular risk, especially in at-risk individuals (overweight population). They support the public health relevance of developing a front-of-pack nutrition label based on this score. Copyright © 2017 Elsevier B.V. All rights reserved.

    Full Text Available Front-of-pack (FOP nutrition labels are considered helpful tools to help consumers making healthier food choices, thus improving their diet. In France, the implementation of a FOP nutrition label-the 5-Colour Nutrition Label (5-CNL-is currently under consideration. Our objective was to investigate dietary profiles in a French adult population using the 5-CNL, and to assess its potential impact in improving the diet through substitution of foods.Subjects included in the NutriNet-Santé cohort, who had completed three 24-h dietary records were included in this cross-sectional analysis. Mutually exclusive clusters of individuals were identified using the percentage of energy derived from foods of each of the 5-CNL colours as input variables. Three scenarios of substitution of foods for healthier alternative using the 5-CNL were tested. Food group and dietary intakes, socio-demographic and lifestyle data were compared across clusters using ANOVAs or Chi-square tests, as appropriate. We identified three mutually exclusive dietary profiles: 'Healthy' (N = 28 095, 29.3% of the sample, with high consumption of fruit, vegetables, whole cereals and fish; 'Western' (N = 33 386, 34.8%; with high consumption of sweetened beverages, breakfast cereal, cheese, fatty and sugary foods; 'Traditional' (N = 34 461, 35.1%, with high consumption of potatoes, bread, meat and dairy desserts. Overall, substitutions strategies led to an increase in the number of subjects reaching the recommended intakes in energy, macro and micronutrients. Increases were particularly high in the 'Western' pattern for lipids and saturates intakes: from 16.2% reaching the recommended amount for lipids (13.5% for saturates to 60.6% and 85.7% respectively.The use of the 5-CNL as an indicator of food choice meaningfully characterizes clusters of dietary habits and appears as an effective tool to help improving the nutritional quality of the diet.

  13. Diagnóstico diferencial das distrofias musculares com referência especial às alterações enzimáticas

    H. Heick

    1967-06-01

    Full Text Available Depois de apresentar os dados clínicos e genéticos relativos a 221 casos de distrofia muscular progressiva (125 casos do tipo Duchenne, 63 do tipo cintura pélvica e 25 do tipo fácio-escápulo-umeral, os autores analisam os resultados das dosagens sôro-enzimáticas que fizeram; em alguns casos foram pesquisas também as atividades de 25 enzimas em homogeneizados de tecido muscular. Os mesmos exames foram feitos em casos de miopatias de outra etiologia e de distrofias musculares neuropáticas e mielopáticas. Foi verificado que o teor das sôro-enzimas aumenta em todas as formas de distrofia muscular progressiva hereditária. No tipo Duchenne as-atividades enzimáticas são elevadas desde o nascimento das crianças acometidas, precedendo o aparecimento da sintomatologia clínica. Com o progredir da moléstia e com o decorrer dos anos os teores sôro-enzimáticos tendem a diminuir, podendo reduzir-se aos valores normais nas fases finais da moléstia. No tecido muscular não existe diferença significante, no que respeita à composição enzimática, entre os diversos tipos de distrofia muscular progressiva e hereditária. Com exceção de poucas enzimas cuja atividade é maior nos tecidos conjuntivo e adiposo que progressivamente substituem o tecido muscular que entra em atrofia, o teor das mio-enzimas diminui com o progredir da moléstia, como expressão do crescente esgotamento do citoplasma da célula muscular. Nas distrofias musculares neuropáticas e mielopáticas as alterações são idênticas, embora de menor intensidade. Algumas diferenças quantitativas podem ser explicadas pela idade dos pacientes e pela intensidade do processo. A mesma diferença pode ser demonstrada mediante exames histopatológicos: nas formas que acometem crianças (Werdnig-Hoffmann as fibras musculares ainda não denervadas se apresentam com aspecto normal, ao passo que, nas formas do adulto (Kugelberg-Welander, possivelmente pelo desgaste provocado pelos esfor

    2006-01-01

    Objective: To evaluate the ability of the volume rendering technique to display the normal and abnormal inner ear structures. Methods: Forty normal earand 61 abnormal inner ears (40 congenital inner ear malformations, 7 labyrinthitis ossificans, and 14 inner ear erosion caused by cholesteatomas) were examined with a MSCT scanner. Axial imaging were performed using the following parameters: 120 kV, 100 mAs, 0.75 mm slice thickness, a pitch factor of 1. The axial images of interested ears were reconstructed with 0.1 mm reconstruction increment and a FOV of 50 mm. The 3D reconstructions were done with volume rendering technique on the workstation. Results: In the subjects without ear disorders a high quality 3D visualization of the inner ear could be achieved. In the patients with inner ear' disorders all inner ear malformations could be clearly displayed on 3D images as follows: (1) Michel deformity (one ear): There was complete absence of all cochlear and vestibular structures. (2) common cavity deformity (3 ears): The cochlea and vestibule were represented by a cystic cavity and couldn't be differentiated from each other. (3)incomplete partition type I (3 ears): The cochlea lacked the entire modiolus and cribriform area, resulting in a cystic appearance. (4) incomplete partition type II (Mondini deformity) (5 ears): The cochlea consisted of 1.5 turns, in which the middle and apical turns coalesced to form a cystic apex. (5) vestibular and semicircular canal malformations (14 ears): Cochlea was normal, vestibule dilated, semicircular canals were absent, hypoplastic or enlarged. (6) dilated vestibular aqueduct (14 ears): The vestibular aqueduct was bell-mouthed. In 7 patients with labyrinthifis ossificans, 3D images failed to clearly show the completeinner ears in 4 ears because of too high ossifications in the membranous labyrinth. In the other 3 ears volume rendering could display the thin cochlea basal turn and the intermittent semicircular canals. In the patients

    Full Text Available O governo brasileiro oferece anualmente mais de um milhão de vagas em universidades públicas e gratuitas. Entretanto, a educação superior no Brasil é altamente progressiva. Neste artigo estudamos como a cobrança pela educação pública de alunos com elevada renda altera o equilíbrio no mercado de educação superior. Tal taxa encoraja alunos mais ricos a buscar a educação particular e aumenta o acesso de alunos carentes às universidades públicas. Mostramos que uma pequena taxa cobrada gera ganhos de bem-estar com uma cota inferior de cerca de R$100.000 por aluno carente extra atendido pelo sistema público.

    2005-03-01

    Full Text Available The aim of this in vitro study was to evaluate by spectrophotometry the influence of the incremental technique and progressive light curing in the microleakage of Class V cavities. Forty samples were prepared with class V cylindrical cavities on the buccal root surface of bovine incisive teeth and filled with composite resin (Z250. The samples were divided into four groups: I: cavity was bulk filled and the composite was light cured for 40 seconds; Group II: cavity was bulk filled and a "soft-start" polymerization was used; Group III: cavity was filled with the incremental technique in two coats and light cured for 40 seconds; Group IV: cavity was filled with the incremental technique in two coats and light cured with "soft-start" polymerization. After the restoration, the specimens were thermally stressed for 3,000 cycles in bath at 5 ± 2°C and 55 ± 2°C, protected with nail enamel, colored with 2% methylene blue and cut into sections. These sections were triturated and the dye was recovered with PA ethanol and the supernatant was evaluated. The data were submitted to ANOVA and the results showed the following averages: bulk filled and conventional photopolymerization (I 0.06075 µg/ml; bulk filled and progressive photopolymerization (II 0.04030 µg/ml; incremental insertion and conventional photopolymerization (III 0.04648 µg/ml; incremental insertion and progressive photopolymerization (IV 0.04339 µg/ml. No significant statistic differences were observed among the mean values. The Degulux "soft-start" equipment probably emits too high initial light intensity to promote progressive photopolymerization.O objetivo deste estudo in vitro foi avaliar através de espectrofotometria a influência das técnicas de inserção incremental e de fotopolimerização progressiva na microinfiltração de cavidades Classe V.

La fenomenologia contemporanea delle migrazioni che interessano il continente europeo mostra una progressiva convergenza delle storie nazionali che si accompagna a un intenso dibattito istituzionale dell’Unione Europea sui margini di comunitarizzazione delle politiche migratorie. Il discorso istituzionale sviluppatosi nell’ultimo decennio consente di identificare alcune tendenze di fondo relative agli sviluppi di una politica migratoria europea e di riflettere criticamente sulle possibilità di individuare nel migrante non comunitario la figura sociale di uno ‘straniero europeo’.

  14. Esclerodermia, tireoidite e miastenia grave: estudo de um caso

    Antonio L. dos Santos Werneck

    1993-11-01

    Full Text Available Uma paciente de 36 anos com miastenia grave desenvolveu após dois anos intolerância ao frio, o que conduziu ao diagnóstico de tireoidite de Hashimoto. Quatro anos mais tarde apresentou pele espessada nas mãos (esclerodermia limitada. O quadro clínico e os exames complementares encaminharam o diagnóstico para a forma CREST de esclerodermia sistêmica progressiva. Discute-se a dificuldade diagnóstica da esclerodermia, assim como suas síndromes de superposição. Doença de Hashimoto e miastenia grave constituem associação pouco frequente. A presença de esclerodermia e miastenia grave é rara. Não encontramos na literatura a coincidência destas três doenças.

    Isabel Ayres Pereira

    2016-07-01

    Comentários: O SBO tem uma penetrância e expressão fenotípica variáveis, estando descritos casos de lesões cutâneas e ósseas isoladamente. A osteopoiquilose é progressiva e mais evidente a partir da puberdade, e a dor óssea está descrita em apenas 25% dos casos e é habitualmente ligeira. Esta é uma entidade benigna sem sequelas a longo prazo, e o seu conheci- mento e suspeição são fulcrais para o diagnóstico precoce permitindo tranquilizar a família e evitar investigações dispendiosas e desnecessárias.

    2013-01-01

    INTRODUÇÃO: A doença renal crônica (DRC) é decorrente de uma lesão renal e perda progressiva e irreversível da função dos rins. A hemodiálise substitui parcialmente essa função, com o objetivo de corrigir as alterações metabólicas na DRC. Para acompanhar a adequação da diálise, é determinado o Kt/V - índice de depuração da ureia por sessão de hemodiálise. O exercício físico de moderada intensidade tem se mostrado de fundamental importância para melhorar os efeitos adversos ao tratamento dialí...

    2016-01-01

    A doença renal crônica (DRC) consiste na perda progressiva e irreversível da função dos rins. No seu estágio mais avançado, a perda da função renal é maior que 85%, sendo necessário o início de algum tipo de terapia renal substitutiva, onde a hemodiálise (HD) é a mais comum. As características do tratamento dialítico tendem a favorecer uma série de fatores negativos, como desnutrição e fraqueza muscular, que apresentam forte associação com a diminuição da independência funcional. Neste sentid...

  5. Panorama dell´italiano in San Paolo nel contesto plurilinguistico brasiliano

    Loredana de Stauber Caprara

    2004-12-01

    Full Text Available O italiano, ou variedades dialetizadas de italiano, no início do século XX era falado aproximadamente pela metade da população de São Paulo. Posteriormente, por diferentes motivos, entre os quais a chegada de outros grupos étinicos e diminuição progressiva de onda imigratória italiana, essa porcentagem diminuiu muito. Agora, quase quarenta anos após o fim do movimento imigratório, a permanência do italiano em São Paulo depende do ensino formal em cursos livres, às vezes com contribuições financeiras italianas, em escolas e universidades públicas brasileiras. Para a atualização linguistica deve-se considerar o suvsídio de RAI International.

    2000-01-01

    Full Text Available Propiltiouracil é uma droga amplamente utilizada no tratamento do hipertiroidismo. A hepatotoxicidade é um dos efeitos colaterais mais raros e também mais graves associados a ela. Relata-se um caso de hepatite aguda colestática que acomete um jovem de 15 anos em uso de propiltiouracil para tratamento de hipertiroidismo. Causas virais, metabólicas e autoimunes foram excluídas e a biopsia hepática revelou achados histopatológicos sugestivos de hepatite colestática induzida por droga. Com a suspensão da droga, houve remissão dos sintomas e normalização progressiva das provas de função hepática.

    Patricia Capua Vieira da Silva

    2011-06-01

    Full Text Available A síndrome de Waardenburg tipo I é uma desordem auditivo-pigmentária que inclui, entre outros, perda auditiva neurossensorial congênita não progressiva, telecanto, distúrbios pigmentares de íris, cabelo e pele. Indivíduos afetados podem ter maior risco de: defeitos no tubo neural, fendas labial e palatina, anormalidades nos membros e doença de Hirschsprung. O diagnóstico é clínico, sendo necessários dois critérios maiores ou um maior e dois menores. PAX3 é o único gene conhecido associado à síndrome, sendo, entretanto, mais usado no aconselhamento genético. Quanto ao diagnóstico diferencial, podemos citar: outras causas de perda auditiva neurossensorial congênita não progressiva, outros tipo de síndrome de Waardenburg, piebaldismo, albinismo, vitiligo e síndrome de Teitz. Neste trabalho, apresenta-se um paciente masculino de 11 anos com diagnóstico de síndrome de Waardenburg tipo I. Ressalta-se a importância do oftalmologista no auxílio do diagnóstico deste raro quadro sistêmico, uma vez que inclui algumas alterações oftalmológicas. O diagnóstico precoce da síndrome permite estimulação adequada para a perda auditiva, assim como medidas preventivas em caso de gestantes afetadas no aconselhamento genético.

    2002-06-01

    Full Text Available The association between multiple (MS sclerosis and cerebral gliomas has been sporadically reported in the literature, causing a long lasting discussion if these lesions occur coincidentally or if MS plaques may actually lead to the genesis of gliomas. We report a 36 year old man who developed a rapid onset of right side weakness and loss of vision, having established a diagnosis of MS which was confirmed by CSF analysis and MRI. Nine years later he developed progressive tetraparesis, leading initially to suspicion of illness relapse and a demyelinating plaque in the spinal cord. However, after MRI investigation, a spinal cord tumor was diagnosed. The patient underwent cervical spine laminotomy for microsurgical removal of the spinal cord tumor diagnosed as ependimoma. The neurological deficits improved significantly.A associação entre esclerose múltipla (EM e gliomas cerebrais foi relatada esporadicamente na literatura, levando a longa discussão quanto à possibilidade das placas de esclerose estarem envolvidas na etiologia dos gliomas ou dessas lesões ocorrerem coincidentemente. Relatamos um paciente de 36 anos que desenvolveu hemiparesia direita rapidamente progressiva e perda visual, sendo estabelecido o diagnóstico de EM após análise do LCR e imagens de RM de encéfalo. Após nove anos o paciente desenvolveu tetraparesia lentamente progressiva, levantando inicialmente a hipótese de atividade da doença e aparecimento de placa de EM na medula espinal. Contudo, após investigação com RM de coluna, um tumor medular foi diagnosticado. Foi então submetido a laminectomia cervical para ressecção microcirúrgica do tumor, que foi diagnosticado como ependimoma. Os déficits neurológicos melhoraram significativamente.

  19. Correlação entre a incapacidade funcional, idade e enzimas séricas nas doenças neuromusculares

    1995-03-01

    Full Text Available Foram estudados 806 casos de diversas doenças neuromusculares, a fim de verificar se existe correlação entre o grau de incapacidade funcional aferida pela escala de Vignos e Archibald (V&A e enzimas séricas (creatinoquinase, desidrogenase lática, aldolase, transaminase glutâmica oxalacética e pirúvica. Foram utilizados testes para a análise do coeficiente de correlação simples (Pearson e múltiplo. Foi encontrada correlação positiva (piora progressiva da incapacidade da V&A com a idade em algumas doenças, como a distrofia muscular de Duchenne, distrofia fascio-escapulo-umeral, distrofia miotônica, miopatias com defeitos enzimáticos da cadeia respiratória e esclerose lateral amiotrófica. Por outro lado, foi detectada correlação negativa (melhora progressiva dos sintomas na miopatia do multicore, miopatia benigna da infância com predomínio de fibras do tipo 1, deficiência de carnitina e dermatomiosite. A V&A mostrou maiores correlações (p< 0,05 entre as diversas enzimas sérícas quando estudadas isoladamente na distrofia muscular de Duchenne, distrofia óculo-crânio-somática, polimiositcs e periarterite nodosa. Quando as enzimas foram analisadas em conjunto, através de teste de correlação múltipla, verificou-se pequena correlação entre elas e a V&A. Esta reduzida interrelação sugere que a utilização de diversas enzimas na análise longitudinal das doenças neuromusculares é limitada, não tendo aplicação pratica, embora sejam muito importantes no diagnóstico.

    Full Text Available A otospongiose é uma osteodistrofia do osso temporal caracterizada pela reabsorção e neoformação óssea desordenada. Clinicamente, caracteriza-se por disacusia condutiva, neurossensorial, e/ou mista, progressiva e zumbidos. O início dos sintomas ocorre entre 30 e 40 anos de idade sendo rara sua manifestação na infância. Descrevemos o caso de um paciente de 11 anos de idade, com quadro de hipoacusia unilateral progressiva há 5 anos. O exame otorrinolaringológico revelou mancha rubra de Schwartze em orelha esquerda. A audiometria, imitanciometria e a tomografia computadorizada demonstraram características sugestivas de otospongiose. Realizamos uma revisão dos aspectos clínicos, diagnósticos e da conduta terapêutica da otospongiose na infância.Otospongiosis is an osteodystrophy of the temporal bone, characterized by disordered neoformation and deposition of bone, characterized by the presence of a progressive conductive, sensorineural or mixed hearing loss and tinnitus. Typically, otospongiosis presents as a slowly progressive conductive hearing loss in the third to fourth decade of life. Uncommonly children and adolescents may also have conductive or sensorineural hearing loss caused by otosclerosis. We describe a case of an 11-year-old patient, with progressive unilateral conductive hearing loss for 5 years. The otoscopic examination revealed a positive Schwartz's sign in the left ear. Audiometry, impedanciometry and CT scan showed characteristics that suggested otospongiosis. We reviewed clinical aspects, diagnosis and the therapeutic approach for otospongiosis in children.

    2013-01-01

    subgrupo das Pneumonias Intersticiais Idiopáticas. Apesar de uma grande variabilidade no tipo de evolução clínica, está inexoravelmente associada a um mau prognóstico. Material e métodos: Foram identificados doentes com FPI, observados na consulta de Doenças Pulmonares Difusas do Centro Hospitalar de São João, Porto, e revistos os seus parâmetros clínicos, funcionais, radiológicos e do lavado broncoalveolar (LBA. A evolução clínica e sobrevivência foram avaliadas, tendo sido igualmente identificados factores prognósticos. Resultados: Foram incluídos 81 doentes com uma média de idade de 63.8 anos. Na altura do diagnóstico, as principais alterações funcionais identificadas foram restrição, redução da difusão pulmonar e da capacidade de exercício. A maioria dos doentes (72.3% apresentou uma evolução clínica lentamente progressiva. Em 10 doentes (13.2%, foi observada uma evolução rapidamente progressiva e 11 (14.5% apresentaram exacerbação aguda. Verificou-se uma associação entre a evolução rapidamente progressiva e uma maior gravidade funcional ao diagnóstico, nomeadamente na Capacidade Vital Forçada (CVF e Capacidade Pulmonar Total (CPT. A sobrevivência mediana foi de 36 meses. Verificou-se uma diferença estatisticamente significativa na sobrevivência entre os diferentes grupos de evolução clínica - 41 meses para os doentes com evolução lentamente progressiva e 9 meses para os doentes com evolução rapidamente progressiva. Valores inferiores de CVF, CPT, distância na Prova da marcha dos 6 minutos e PaO2 em repouso, bem como o maior grau de neutrofilia no LBA estiveram associados a uma sobrevivência inferior em análise univariada. Conclusão: A análise deste grupo de doentes com FPI confirma a existência de 2 fenótipos claramente distintos, o de evolução lenta e o de evolução rapidamente

  4. ELBOW AND WRIST INJURIES IN SPORTS

    Marmor, Leonard; Bechtol, Charles O.

    1960-01-01

    Any disabling injury of the elbow or wrist should be studied roentgenographically for evidence of fracture which may not be otherwise evident but which may cause permanent disability unless the joint is immobilized for healing. “Tennis elbow” may be treated with physical therapy and analgesic injection but may require splinting or tendon stripping. Elbow sprain can occur in the growing epiphysis but is rare in adults. A jarring fall on the hand may cause fracture or dislocation at the elbow. Full extension of the joint should be restored gradually by active exercise rather than passive or forcible stretching. Fracture at the head of the radius may cause joint hemorrhage with severe pain which can be relieved by aspiration. A displacing fracture at the head of the radius requires removal of the head to prevent arthritic changes. Myositis ossificans contraindicates operation until after it has cleared. Healing of wrist fractures may be facilitated by exercise of the shoulder and elbow while the wrist is still in a cast. Fractures of the navicular bone are difficult to detect even roentgenographically and splinting may have to be done on clinical evidence alone. PMID:14421374

  5. Melorheostosis: a review of 23 cases

    Freyschmidt, J. [Dept. of Radiology, Zentralkrankenhaus Bremen (Germany)

    2001-03-01

    The aim of this study was to review clinical and radiological signs of melorheostosis in a large series of cases. Family history, patient history, clinical data and radiological features of 23 consecutive cases of melorheostosis were investigated. Criteria for establishing the diagnosis ''melorheostosis'' were defined. Sixteen patients (mean age 34 years, equal ratio between genders) had chronic pain in the affected limb(s) and/or subcutaneous fibrosis and/or various skin lesions. Number of involved bones: one bone (n = 10); two bones (n = 4); three or more bones (n = 9). Anatomic distribution: upper extremity (n = 5); lower extremity (n = 16); upper and lower extremity (n = 1); sacrum (n = 1). Radiologic pattern: osteoma-like (n = 7); classic candle wax appearance (n = 5); myositis ossificans-like (n = 1); osteopathia striata-like (n = 6); mixed pattern (n = 4). Patterns different from the appearance formerly judged to be ''classic'' prevail. The standard concept of disease manifestation has to be adjusted. Pathogenesis remains unclear. The classic theory claims the presence of an early embryonic infection of a sensory nerve inducing changes in the respective sclerotome, but we propose the concept of mosaicism as a better explanation for the sporadic occurrence, the asymmetric ''segmental'' pattern with variable extent of involvement and equal gender ratio of the disease.

    To determine whether proton magnetic resonance spectroscopy (1H-MRS) can help differentiate between benign and malignant soft tissue lesions, and to assess if there is a correlation between 1H-MRS data and the mitotic index. MR measurements were performed in 43 patients with soft tissue tumours >15 mm in diameter. Six cases were excluded for technical failure. Examinations were performed at 1.5 T using a single-voxel point resolved spectroscopy sequence (PRESS) with TR/TE = 2000/150 ms. The volume of interest was positioned within the lesion avoiding inclusion of necrotic regions. In all patients, a histological diagnosis was obtained and the corresponding mitotic index was also computed. 1H-MRS results and histopathological findings were compared using the chi-squared test and correlation coefficient. Choline was detected in 18/19 patients with malignant tumours and in 3/18 patients with benign lesions. The three benign lesions included one desmoid tumour, one ossificans myositis and one eccrine spiradenoma. Choline was not detected in 15 patients with benign lesions or in one patient with dermatofibrosarcoma protuberans. Resulting 1H-MRS sensitivity and specificity were 95% and 83% respectively. Absence of choline peak is highly predictive of benign tumours suggesting that 1H-MRS can help to differentiate malignant from benign tumours. (orig.)

  7. [New insights of myositis-specific and -associated autoantibodies in juvenile and adult type myositis].

    Váncsa, Andrea; Dankó, Katalin

    2016-07-01

    Myositis, which means inflammation of the muscles, is a general term used for inflammatory myopathies. Myositis is a rare idiopathic autoimmune disease. It is believed that environmental factors such as virus, bacteria, parasites, direct injuries, drugs side effect can trigger the immune system of genetically susceptible individuals to act against muscle tissues. There are several types of myositis with the same systemic symptoms such as muscle weakness, fatigue, muscle pain and inflammation. These include dermatomyositis, juvenile dermatomyositis, inclusion-body myositis, polymyositis, orbital myositis and myositis ossificans. Juvenile and adult dermatomyositis are chronic, immune-mediated inflammatory myopathies characterized by progressive proximal muscle weakness and typical skin symptoms. The aim of the authors was to compare the symptoms, laboratory and serological findings and disease course in children and adult patients with idiopathic inflammatory myopathy. Early diagnosis and aggressive immunosuppressive treatment improve the mortality of these patients. Myositis-specific autoantibodies have predictive and prognostic values regarding the associated overlap disease, response to treatment and disease course. The authors intend to lighten the clinical and pathogenetic significance of the new target autoantigens. Orv. Hetil., 2016, 157(29), 1179-1184.

  8. A large parosteal ossifying lipoma of lower limb encircling the femur

    2014-01-01

    Introduction Lipoma is a benign soft tissue neoplasm that may contain mesenchymal elements, as a result of metaplastic process. Ossification in benign and malignant soft tissue tumors can also manifest due to metaplastic process. Case presentation A 45 year old woman presented with a large thigh mass. The mass was developed one and a half year ago which insidiously increased in size and was associated with movement restriction. Radiological findings revealed soft tissue neoplasm on antero-medial aspect of thigh encircling the femur and displacing adjacent muscles. Fine trabeculations were seen in neoplasm suggestive of ossification. Excision of the mass was performed and histopathology revealed adipocytes with mature bony trabeculae possessing prominent osteoblastic rimming suggestive of ossifying lipoma. Conclusion It is important to recognize this variant of lipoma as it is associated with a better clinical outcome in contrast to most of the deep seated soft tissue neoplasms. Secondly it should also be differentiated from myositis ossificans and heterologous differentiation in other soft tissue neoplasms. We suggest an algorithmic approach to the diagnosis of ossifying soft tissue neoplasms histopathologically. Mature bony trabeculae with prominent osteoblastic rimming in a soft tissue lesion are due to a metaplastic process and should not be confused with osteosarcoma. PMID:24433545

  10. On the importance of considering disease subtypes: Earliest detection of a parosteal osteosarcoma? Differential diagnosis of an osteosarcoma in an Anglo-Saxon female.

    Ferrante di Ruffano, Lavinia; Waldron, Tony

    2016-12-30

    A case of potentially dedifferentiated parosteal osteosarcoma was found in the proximal humerus of an adult female buried in the late Anglo-Saxon cemetery of Cherry Hinton, Cambridgeshire, UK. Key features include a large, dense, lobulated mass attached to the medial metaphysis of the proximal humerus by a broad-based attachment, accompanied by cortical destruction and widespread spiculated periosteal reaction. Radiographic images confirm medullary involvement, lack of continuity between the cortex and external mass, a radiolucent cleavage plane and possible radiolucent zones within the bony masses. Differential diagnoses considered include osteochondroma, myositis ossificans, fracture callus, as well as the primary malignancies of osteosarcoma and chondrosarcoma, and their various subtypes. The macroscopic and radiographic analysis of the tumor is described and discussed within clinical and paleopathological contexts. One of only 19 uncontested examples of osteosarcoma from past human populations, most of which remain unconfirmed, this case represents what we believe to be the earliest, and probably singular, bioarcheological example of parosteal osteosarcoma in human history.

    The purpose of this study was to assess the diagnostic and differential diagnostic value of high-resolution computed tomography in the evaluation of temporal-bone dystrophies. The study group included 55 patients with osseous abnormalities of the temporal bone in general, and the labyrinthine capsule in particular. In 27 patients the CT scan revealed evidence of otodystrophic lesions. The CT findings in patients with otosclerosis (21 patients), osteogenesis imperfecta (two patients), fibrous dysplasia (one patient). Paget's disease (one patient) and osteoporosis (two patients) are described. The CT scans of 17 patients revealed secondary osseous lesions due to metastasis (five patients), post-inflammatory changes (10 patients) or labyrinthitis ossificans (two patients). Normal variants and congenital mineralization defects were diagnosed in nine patients, Down's syndrome in two. Our results indicate the importance of high-resolution computed tomography as the primary imaging modality in evaluating osseous lesions of the temporal bone and labyrinth.

  12. Pitfalls in the MR diagnosis of primary malignant bone tumors

    Bader, T.R.

    1998-01-01

    MRI has gained an undisputed place in the evaluation of malignant bone tumors, not only for verifying results of conventional radiography and clarifying differential diagnoses; it has also become increasingly important for the assessment of the malignant/benign nature of the tumor, its growth rate, definition of adequate sites for biopsy, local preoperative staging, and evaluation of the response to chemotherapy. However, several pitfalls have to be observed regarding choice of technical parameters (coils, sequences, imaging planes), tissue differentiation, and tumor staging. When staging malignant tumors, critical aspects which have to be observed are tumor extension, integrity of the cortical bone, soft tissue components, infiltration of a joint or neurovascular bundle. The use of contrast agents provides important additional information but can also give rise to misinterpretations. Thus, all features of a tumor have to be observed in order to establish a final diagnosis. Particular difficulties can occur with the interpretation of MR images of osteomyelitis, osteoid osteoma, stress and insufficiency fractures, bone infarcts, myositis ossificans, hemangiomas, and aneurysmal bone cysts.

    The assessment was introduced of 24-hour whole-body retention of 99m Tc-methylene diphosphonate by estimating the amount excreted in urine per 24 hours. The mean value ± standard deviation of 34 subjects without disorders of the skeleton, aged 22 to 70 years, is 34.8±7.1%: 23 men with a value of 35.9±7.4% and 11 women with 32.4±6.3%. The results in pathological conditions (in parentheses the number of examinations): primary hyperparathyroidism (13) 58.4±4.7% (p<0.01); osteoporosis (11) 34.2±3.3% (NS); osteomalacia (16) 59.1±3.8% (p<0.01); acromegaly (10) 37.4±4.1% (NS); not evaluated by statistical methods: Paget's disease (6) 50.4%; multiple metastases in bones (3) 60.7%; malnutritional states (6) 50.5%; myositis ossificans (1) 67.8%. Normal and pathological results are consistent with assumptions and the available experience. The method appears to be a suitable indicator of the metabolic activity of the skeleton for clinical diagnosis and research. (author)

    Acquired resistance to Tamoxifen remains a critical problem in breast cancer patient treatment, yet the underlying causes of resistance have not been fully elucidated. Abberations in the Wnt signalling pathway have been linked to many human cancers, including breast cancer, and appear to be associated with more metastatic and aggressive types of cancer. Here, our aim was to investigate if this key pathway was involved in acquired Tamoxifen resistance, and could be targeted therapeutically. An in vitro model of acquired Tamoxifen resistance (named TamR) was generated by growing the estrogen receptor alpha (ER) positive MCF7 breast cancer cell line in increasing concentrations of Tamoxifen (up to 5 uM). Alterations in the Wnt signalling pathway and epithelial to mesenchymal transition (EMT) in response to Tamoxifen and treatment with the Wnt inhibitor, IWP-2 were measured via quantitative RT-PCR (qPCR) and TOP/FOP Wnt reporter assays. Resistance to Tamoxifen, and effects of IWP-2 treatment were determined by MTT proliferation assays. TamR cells exhibited increased Wnt signalling as measured via the TOP/FOP Wnt luciferase reporter assays. Genes associated with both the β-catenin dependent (AXIN2, MYC, CSNK1A1) and independent arms (ROR2, JUN), as well as general Wnt secretion (PORCN) of the Wnt signalling pathway were upregulated in the TamR cells compared to the parental MCF7 cell line. Treatment of the TamR cell line with human recombinant Wnt3a (rWnt3a) further increased the resistance of both MCF7 and TamR cells to the anti-proliferative effects of Tamoxifen treatment. TamR cells demonstrated increased expression of EMT markers (VIM, TWIST1, SNAI2) and decreased CDH1, which may contribute to their resistance to Tamoxifen. Treatment with the Wnt inhibitor, IWP-2 inhibited cell proliferation and markers of EMT. These data support the role of the Wnt signalling pathway in acquired resistance to Tamoxifen.

  17. Visual-gustatory interaction: orbitofrontal and insular cortices mediate the effect of high-calorie visual food cues on taste pleasantness.

    Vision provides a primary sensory input for food perception. It raises expectations on taste and nutritional value and drives acceptance or rejection. So far, the impact of visual food cues varying in energy content on subsequent taste integration remains unexplored. Using electrical neuroimaging, we assessed whether high- and low-calorie food cues differentially influence the brain processing and perception of a subsequent neutral electric taste. When viewing high-calorie food images, participants reported the subsequent taste to be more pleasant than when low-calorie food images preceded the identical taste. Moreover, the taste-evoked neural activity was stronger in the bilateral insula and the adjacent frontal operculum (FOP) within 100 ms after taste onset when preceded by high- versus low-calorie cues. A similar pattern evolved in the anterior cingulate (ACC) and medial orbitofrontal cortex (OFC) around 180 ms, as well as, in the right insula, around 360 ms. The activation differences in the OFC correlated positively with changes in taste pleasantness, a finding that is an accord with the role of the OFC in the hedonic evaluation of taste. Later activation differences in the right insula likely indicate revaluation of interoceptive taste awareness. Our findings reveal previously unknown mechanisms of cross-modal, visual-gustatory, sensory interactions underlying food evaluation.

  18. Quantitative scintigraphy of the sacroiliac joints and spinal column in Bechterev's disease (spondylitis ankylopoetica)

    Mlychkov, Kh.

    1982-01-01

    Quantitative scintigraphy of the sacroiliac joints and the spinal column was performed in 138 patients with verified Bechterev's disease and in a control group of 104 healthy subjects, who had no clinical, roentgenographic and laboratory evidence of illness of the sacroiliac joints and the spinal column. By comparing skeletal ''zones of interest'' the author studied the following quantitative parameters: sacroiliac index (separately fop the right and left sacpoiliac joint); C 7 /sacrum jndex; D 10 /sacrum and L 4 /sacrum indices. The main values of these indices in the control group were accordingly 114.5 and 113.7 (for the right and left sacroiliac joints); 59; 95; 90. In patients with Bechterev's disease these indices were raised: 154 and 149 (for right and left sacroiliac joints); 75; 123; 113. Peak diagnostic value have the sacroiliac indices and the D 10 /sacrum, index, which appeared to be elevated in more than 95 per cent of the tested patients with verified Bechterev's disease.

    2013-09-01

    Little is known about the impact of n3 (ω3) PUFAs on polarization of CD4(+) T cells into effector subsets other than Th1 and Th2. We assessed the effects of dietary fat [corn oil (CO) vs. fish oil (FO)] and fermentable fiber [cellulose (C) vs. pectin (P)] (2 × 2 design) in male C57BL/6 mice fed CO-C, CO-P, FO-C, or FO-P diets for 3 wk on the ex vivo polarization of purified splenic CD4(+) T cells (using magnetic microbeads) into regulatory T cells [Tregs; forkhead box P3 (Foxp3(+)) cells] or Th17 cells [interleukin (IL)-17A(+) and retinoic acid receptor-related orphan receptor (ROR) γτ(+) cells] by flow cytometry. Treg polarization was unaffected by diet; however, FO independently reduced the percentage of both CD4(+) IL-17A(+) (P diets enriched in eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), or DHA + EPA similarly reduced Th17-cell polarization in comparison to CO by reducing expression of the Th17-cell signature cytokine (IL-17A; P = 0.0015) and transcription factor (RORγτ P = 0.02), whereas Treg polarization was unaffected. Collectively, these data show that n3 PUFAs exert a direct effect on the development of Th17 cells in healthy mice, implicating a novel n3 PUFA-dependent, anti-inflammatory mechanism of action via the suppression of the initial development of this inflammatory T-cell subset.

    In spite of its recognized benefits in the treatment of malignant tumors, radiation therapy have several side effects in the head and neck region. The evaluation of oral conditions by a dentist is important to prevent or minimize these problems. The aim of this retrospective review was to analyze the dental needs in 357 patients who received radiotherapy in the head and neck region and were treated at Orocentro/FOP/UNICAMP, between January 1990 and December 2004. Review of patient files showed that dental examination before radiotherapy was not performed in 148 patients (41.5%) and was done in 209 patients (58.5%). From the total of examined patients, 94 (45%) did not require dental procedures at the moment of examination, while 115 (55%) presented some sort of dental need. Following the patients after the radiotherapy, it was observed that the group of patients that was evaluated before radiation presented less need of restorations, root canal filling and dental extractions than those who were not evaluated. The results of this study confirm that the evaluation of oral conditions prior to radiotherapy is essential to minimize the dental needs, emphasizing the importance of the dentist in the multidisciplinary team that treats cancer patients.

  3. Merge processing in the human brain: a sub-region based functional investigation in the left pars opercularis

    Emiliano eZaccarella

    2015-11-01

    Full Text Available Language is thought to represent one of the most complex cognitive functions in humans. Here we break down complexity of language to its most basic syntactic computation which hierarchically binds single words together to form larger phrases and sentences. So far, the neural implementation of this basic operation has only been inferred indirectly from studies investigating more complex linguistic phenomena. In the present sub-region based functional magnetic resonance imaging (fMRI study we directly assessed the neuroanatomical nature of this process. Our results showed that syntactic phrases—compared to word-list sequences—corresponded to increased neural activity in the ventral-anterior portion of the left pars opercularis (Brodmann Area (BA 44, whereas the adjacently located deep frontal operculum/anterior insula (FOP/aINS, a phylogenetically older and less specialized region, was found to be equally active for both conditions. Crucially, the functional activity of syntactic binding was confined to one out of five clusters proposed by a recent fine-grained sub-anatomical parcellation for BA 44, with consistency across individuals. Neuroanatomically, the present results call for a redefinition of BA 44 as a region with internal functional specializations. Neurocomputationally, they support the idea of invariance within BA 44 in the location of activation across participants for basic syntactic building processing.

    2017-08-08

    We investigated the effects of tumor suppressor candidate 3 ( TUSC3 ) on autophagy in human non-small cell lung cancer (NSCLC) cells. A total of 118 NSCLC patients (88 males and 30 females) who underwent surgery at our institute were enrolled in the study. Immunohistochemical analysis revealed that TUSC3 protein expression was lower in NSCLC specimens than adjacent normal tissue. Correspondingly, there was greater methylation of TUSC3 in NSCLC than adjacent normal tissue. After transient transfection of A549 NSCLC cells with constructs designed to up-regulate or down-regulate TUSC3 expression, we analyzed the effects of inhibiting the Wnt pathway (XAV939) and autophagy (chloroquine, CQ) on the behavior of NSCLC cells. We also performed TOP/FOP-Flash reporter assays, MTT assays, Annexin V-FITC/propidium iodide staining, and acridine orange staining to evaluate Wnt/β-catenin signaling, cell proliferation, apoptosis, and autophagy, respectively. Expression of Wnt/β-catenin pathway components and autophagy-related proteins was analyzed using qRT-PCR and Western blotting. We found that TUSC3 inhibited cell proliferation and promoted both apoptosis and autophagy in A549 cells. In addition, TUSC3 increased expression of autophagy-related proteins. It also increased expression of Wnt/β-catenin signaling pathway components and promoted nuclear transfer of β-catenin, resulting in activation of Wnt/β-catenin signaling. TUSC3 thus induces autophagy in human NSCLC cells through activation of the Wnt/β-catenin signaling pathway.

    2018-01-01

    The Tillinghast Reflector Echelle Spectrograph (TRES) on the 1.5-m Tillinghast Reflector at the Fred L. Whipple Observatory on Mount Hopkins has been a workhorse for reconnaissance spectroscopy of transiting-planet candidates identified by a variety of ground- and space-based photometric surveys, including Vulcan, TrES, HATNet, KELT, QES, Kepler, and K2. In support of NASA missions, quick-look classifications of effective temperature, surface gravity, metallicity, line broadening due to rotation, and absolute radial velocity have been uploaded to ExoFOP at NExScI on a timely schedule. More careful results derived using the Stellar Parameter Classification (SPC) tool can be provided in support of publications. For example, SPC results for effective temperature and metallicity have been used extensively to help constrain asteroseismic analyses of Kepler and K2 targets. TRES has also been used effectively for orbital solutions, Rossiter-McLaughlin observations, and Doppler tomography of large planets orbiting brighter. We look forward to continuing this work on TESS Objects of Interest.

    Full Text Available Diagnosis in neuroimaging involves the recognition of specific patterns indicative of particular diseases. Pareidolia, the misperception of vague or obscure stimuli being perceived as something clear and distinct, is somewhat beneficial for the physician in the pursuit of diagnostic strategies. Animals may be pareidolically recognized in neuroimages according to the presence of specific diseases. By associating a given radiological aspect with an animal, doctors improve their diagnostic skills and reinforce mnemonic strategies in radiology practice. The most important pareidolical perceptions of animals in neuroimaging are the hummingbird sign in progressive supranuclear palsy, the panda sign in Wilson's disease, the panda sign in sarcoidosis, the butterfly sign in glioblastomas, the butterfly sign in progressive scoliosis and horizontal gaze palsy, the elephant sign in Alzheimer's disease and the eye-of-the-tiger sign in pantothenate kinase-associated neurodegenerative disease.O diagnóstico em neuroimagem envolve o reconhecimento de padrões específicos indicativos de doenças particulares. Pareidolia, é a perceção equivocada de algo claro e distinto a partir de um estímulo vago e obscuro, por vezes benéfico a quem interpreta exames de imagem na procura do diagnóstico. A este propósito, alguns animais podem pareidolicamente ser reconhecidos em neuroimagens associadas a determinadas doenças específicas, promovendo mais rapidez na habilidade diagnóstica e naturalmente reforçando estratégias mnemônicas individuais na prática do diagnóstico neuroradiológico. Alguns dos sinais de neuroimagens relacionados a percepções pareidolicas de animais são: o sinal do beja-flor na paralisia supra nuclear progressiva; o sinal do panda na doença de Wilson; o sinal do panda na sarcoisdose; o sinal da borboleta no glioblastoma; o sinal da borboleta no escoliose progressiva e paralisia do olhar horizontal; o sinal do elefante na doença de

    Full Text Available Este artigo analisa os impactos distributivos e macroeconômicos de curto e longo prazo de duas reformas tributárias alternativas, utilizando um modelo de equilíbrio geral dinâmico com agentes heterogêneos e acumulação de capital. As duas propostas concentram a tributação sobre o consumo, sendo que na primeira as alíquotas efetivas entre as famílias são quase idênticas enquanto que na segunda elas são progressivas. Os principais resultados macroeconômicos das duas propostas sugerem um aumento da produção, do consumo, das horas de trabalho e do estoque de capital com ganhos no bem-estar agregado. Do ponto de vista desagregado, o que se observa é que os maiores ganhos se concentraram nos mais pobres, com aumento do consumo e das horas trabalhadas para todas as famílias. A primeira proposta teve menores ganhos de eficiência e ao não diferenciar as alíquotas do consumo implicou em mais desigualdade e menos progressividade no sistema tributário nacional. A segunda proposta, com tributação sobre o consumo progressiva, foi capaz de trazer maiores ganhos de eficiência, ganhos de progressividade na tributação, além de pequena redução da desigualdade.This paper aims to analyze the distributive as well as macroeconomic impacts of two alternative tax reform proposals. To this end, a dynamic general equilibrium model with six heterogeneous agents' types and capital accumulation is built. The two considered proposals focuses on consumption taxes. The first one implements a nearly flat tax rate on consumption whereas the second one uses a progressive tax rate. The main macroeconomic finding is that both proposals lead to an increase in production, consumption, working hours, capital stock and aggregate welfare. On the disaggregated level, the poor families are the most benefited from the considered tax reform schedules, but all types increased their consumption as well as working hours. The first proposal generates little

Dois grupos eutireóideos, um castrado e o outro não, foram mantidos nas mesmas condições e serviram de controle. Ao final de cada período, foram colhidos o plasma, para determinação da concentração de T4 livre, o cálcio e o fósforo e as paratireóides, para análise morfológica e determinação da porcentagem de núcleo, citoplasma e estroma. Aos 90 dias houve reversão da hipocalcemia observada aos 60 dias nos animais eutireóideos castrados e não castrados, graças à hipertrofia da paratireóide. O mesmo não ocorreu com os grupos hipertireóideos que apresentaram hipocalcemia e hiperfosfatemia progressivas e não compensadas até os 90 dias. Na castração há pronta reversão da hipocalcemia em resposta ao aumento da atividade funcional da paratireóide. No estado hipertireóideo com gônadas funcionais, apesar da hipertrofia da paratireóide, não há retorno à isocalcemia e isofosfatemia. Na associação hipertireoidismo-castração, a paratireóide não responde satisfatoriamente à hipocalcemia e hiperfosfatemia intensas e progressivas.Eighty four parathyroids of castrated and intact adult female Wistar rats kept under hyperthyroidism state for 30, 60 or 90 days were studied. Two euthyroid goups, one castrated and another intact were used as controls. At the end of each period, blood was collected and the concentrations of free T4, calcium and phosphorus were determined. The parathyroids were analysed microscopically and % of nuclei, cytoplasm and stroma were determined. Hypocalcemia that was observed in castrated and intact euthyroid rats at 60 days was reverted after 90 days due to parathyroid hypertrophy. In hyperthyroid groups, hypocalcemia and hyperphosphatemia were progressive and did not revert at 90 days. In conclusion, castration revert hypocalcemia due to

Under Dante de Oliveira's Government (1994-1998, this Union has been striving to regulate the 1989 constitutional clause that determines a progressive integration of the network of state and municipal schools into a one and only Schooling System. Mechanisms have been created to involve the population that uses public schools (parents and students in the deliberation and decision about educational policies; these mechanisms have been designed to favour the construction and the widening of the public sphere of rights. The regulation came to nothing and the mechanisms are still to consolidate. Nowadays, this frustrated experience should be resumed in a critical way, with new proposals. The Union is now more experienced and should reopen the process with the intention to achieve it.

    Full Text Available The differential diagnosis of Parkinsonism based on clinical features, sometimes may be difficult. Diagnostic tests in these cases might be useful, especially magnetic resonance imaging, a noninvasive exam, not as expensive as positron emission tomography, and provides a good basis for anatomical analysis. The magnetic resonance spectroscopy analyzes cerebral metabolism, yielding inconsistent results in parkinsonian disorders. We selected 40 individuals for magnetic resonance imaging and spectroscopy analysis, 12 with Parkinson's disease, 11 with progressive supranuclear palsy, 7 with multiple system atrophy (parkinsonian type, and 10 individuals without any psychiatric or neurological disorders (controls. Clinical scales included Hoenh and Yahr, unified Parkinson's disease rating scale and mini mental status examination. The results showed that patients with Parkinson's disease and controls presented the same aspects on neuroimaging, with few or absence of abnormalities, and supranuclear progressive palsy and multiple system atrophy showed abnormalities, some of which statistically significant. Thus, magnetic resonance imaging and spectroscopy could be useful as a tool in differential diagnosis of Parkinsonism.O diagnóstico diferencial do parkinsonismo baseado em parâmetros clínicos pode ser difícil.

    Full Text Available Resumo: A osteonecrose da mandíbula (ONM pode surgir como complicação do tratamento com bifosfonatos. Esta patologia tem sido descrita em doentes com cancro e o seu desenvolvimento associado a exposição prolongada a altas doses de bifosfonatos. Má higiene dentária, história de uso de próteses ou extração dentária, quimioterapia, corticosteroides e radioterapia da cabeça e pescoço são fatores de risco reportados. Nas fases iniciais pode ser assintomática, contudo, o doente posteriormente desenvolve dor significativa e exposição óssea progressiva. Os autores descrevem 3 casos de ONM em doentes com cancro do pulmão após exposição prolongada a bifosfonatos e na presença de fatores de risco conhecidos. A ONM pode atingir seriamente a qualidade de vida dos doentes com cancro. O diagnóstico precoce poderá reduzir ou mesmo evitar as consequências da lesão óssea progressiva. Abstract: Osteonecrosis of the jaw (ONJ can occur as a complication of bisphosphonate therapy. This condition has been described in cancer patients and its development has been associated with prolonged exposure to high doses of bisphosphonates. Bad dental hygiene, a history of prosthesis or dental extraction, chemotherapy, corticosteroids, and radiation therapy of the head and neck are risk factors reported. In the initial stages it may be asymptomatic, but the patient subsequently develops severe pain and progressive exposed bone. The authors describe three cases of ONJ in lung cancer patients after prolonged exposure to bisphosphonates and there were known risk factors. ONJ can seriously affect the quality of life of cancer patients. An early diagnosis may reduce or avoid the consequences of progressive bone lesion.

Tampouco houve diferença entre as variáveis após capacitação e após incubação no sêmen resfriado, mas, no congelado, a concentração foi significativamente superior após capacitação. CONCLUSÕES: embora a concentração e a motilidade progressiva não tenham diferido em ambas as técnicas, sugere-se o uso do resfriamento em procedimentos específicos a curto prazo, devido à simplicidade e baixo custo. Quando o sêmen congelado for necessário, recomenda-se a utilização logo após a capacitação para evitar redução da qualidade do mesmo.

  19. Iontophoresis: principles and applications

    Eddy Krueger

    Full Text Available Introduction Iontophoresis is a noninvasive technique used to increase transdermal penetration of substances through the skin layer (epidermis, dermis and hypodermis in a controlled manner. Technological advance in recent decades have provided reduced cost of equipment needed for implementation, which allowed for the expansion of this technique. Objective The aim of this paper is to present the state of the art on iontophoresis, ranging from the atomic characteristics of the ion formation to the current applications of the technique. Methods Were researched papers from databases: IOP publishing, ScienceDirect, Pubmed, Springer, IEEE Xplore, Google Scholar and books with keywords iontophoresis, ions, topical applications between 1967 and 2010. Results Were selected (number of papers and database 1 IOP Publishing, 1 from ScienceDirect, Central, 1 from Springer, 2 from PubMed, 11 from IEEE Xplore, 35 from Google Scholar, and 15 books, totaling 66 references and websites with nationally marketed electrotherapy products. Conclusion Iontophoresis is suitable for applications such as acetic acid (calcific tendinitis and myositis ossificans, calcium chloride and magnesium sulfate (control of musculoskeletal spasms, dexamethasone (inflammation, lidocaine (inflammation of soft tissues, zinc oxide (rheumatoid arthritis. It is also used in cosmetic applications with devices attached to the skin and for eye treatment aimed at specific tissues of the eye, providing a treatment option for various eye diseases, reducing the complications secondary to traditional methods of treatment. The advantages are the significant increase in the release and control of therapeutic agents, including drugs with high molecular weight. The disadvantages of iontophoresis are the complexity of the drug release system and prolonged exposure of the skin to an electrical current.

  20. Topographic Locomotive Analysis of 99mTc-HDP Uptake of Acute Rhabdomyolysis and Musculotendinous Unit Injury due to Excessive Swimming Exercise in Novice: A Case Report

    Bahk, Yong Whee; Jeon, Ho Seung

    2008-01-01

    Rhabdomyolysis (RM), also referred to as myonecrosis, is not an uncommon disorder of skeletal muscle, the incidence of which is on the increase as endurance tests, sports and body build have become popular. RM is divided into diffuse muscle fiber damage and musculotendinous unit (MTU) injury. A recent study by Crenshaw et al. revealed that muscular fiber damage caused by racing was associated with elevated intra-muscular pressure, capillary damage, and ischchemia. It is to be remembered that myocytes are mainly destroyed in RM whereas perimysial connective is predominantly damaged in myositis ossificans. When muscle fibers disrupt myoglobin escapes into extracellular fluid and plasma resulting in myoglobinemia and often acute renal failure. Plasma creatine phosphokinase level becomes elevated. We report a case of strenuous swimming-related RM that occurred in the muscles of the shoulder girdles and chest wall analyzed using magnified 9 :9 m Tc-HDP bone scan. Of interest magnified bone scan of RM in the present case showed not only ordinary muscular injury but also MTU injury. MRI is useful in the study of soft tissue injury and in recent years sonography has also become increasingly used. As mentioned 99m Tc-HDP bone scan, especially magnification scan, sensitively depicts metabolic change that occurred in injured muscles and tendons. Unless injury is trivial the bone scan nearly always reveals pathological uptake in a damaged muscle, MTU, and/or tendinous insertion permitting the topographic distinction of injury. Thus, the diagnosis of myolysis, MTU injury, and enthesitis can specifically be made when one uses magnification technique

    1986-01-01

    Computed tomographic (CT) scans of the shoulder girdle, upper arm, waist, pelvic girdle, thigh, and lower leg were obtained in a total of 21 patients with neuromuscular diseases, including 10 with Duchenne muscle dystrophy (DMD), 3 with Fukushima type congenital muscular dystrophy (FCMD), 3 with Werdnig-Hoffmann's disease (WH), 3 with autosomal recessive muscular dystrophy in childhood (childhood MC), one with nemaline myopathy (NM), and one with myositis ossificans circumscripta (MOC). Age-dependent changes in CT findings were examined in the 10 DMD patients ranging in age from 3 to 15 years. Each muscle of the shoulder girdle and upper arm was seen as a low density area on CT in patients 9 years of age when the arms are difficult to elevate. Changes in the m. quadriceps femoris occurring in all the patients were visible earlist on CT, followed by those in the m. gluteus maximus, m. gastrocnemius, and m. soleus. CT scans of the thigh was thus considered most useful in diagnosing DMD. CT scans of the lower leg showed low density areas in the m. gastrocnemius and m. soleus in both WH and FCMD patients, while a low density area seen in the m. gluteus maximum on CT was restricted to FCMD patients. This suggests the potential of CT in the differentiation of WH from FCMD. In patients with childhood ARMD, there were various CT findings including normal and extremely low density areas. CT findings in NM patients were similar to those in DMD patients. High density areas were seen along the fascia of the trunk in MOC patients. (Namekawa, K.)

    Rhabdomyolysis (RM), also referred to as myonecrosis, is not an uncommon disorder of skeletal muscle, the incidence of which is on the increase as endurance tests, sports and body build have become popular. RM is divided into diffuse muscle fiber damage and musculotendinous unit (MTU) injury. A recent study by Crenshaw et al. revealed that muscular fiber damage caused by racing was associated with elevated intra-muscular pressure, capillary damage, and ischchemia. It is to be remembered that myocytes are mainly destroyed in RM whereas perimysial connective is predominantly damaged in myositis ossificans. When muscle fibers disrupt myoglobin escapes into extracellular fluid and plasma resulting in myoglobinemia and often acute renal failure. Plasma creatine phosphokinase level becomes elevated. We report a case of strenuous swimming-related RM that occurred in the muscles of the shoulder girdles and chest wall analyzed using magnified {sup 9}:9{sup m}Tc-HDP bone scan. Of interest magnified bone scan of RM in the present case showed not only ordinary muscular injury but also MTU injury. MRI is useful in the study of soft tissue injury and in recent years sonography has also become increasingly used. As mentioned {sup 99m}Tc-HDP bone scan, especially magnification scan, sensitively depicts metabolic change that occurred in injured muscles and tendons. Unless injury is trivial the bone scan nearly always reveals pathological uptake in a damaged muscle, MTU, and/or tendinous insertion permitting the topographic distinction of injury. Thus, the diagnosis of myolysis, MTU injury, and enthesitis can specifically be made when one uses magnification technique.

    Full Text Available We report two patients with central neurocytomas at an uncommon location in the brain. The first, a 58-year-old man presenting with signs and symptoms of increased intracranial pressure, had a tumor located at the pineal region. The second, a 21-year-old woman with tumor in the aqueductal region had worsening migraine-like headaches and diplopia. Both patients had obstructive hydrocephalus treated by neuroendoscopic third ventriculostomy and biopsy of the tumors. No additional treatment was done. We conclude that neurocytomas should be considered in the differential diagnosis of tumors located in the pineal and aqueductal regions.Relatamos dois pacientes com neurocitoma central com localização incomum no sistema nervoso central. O primeiro, 58 anos, masculino, apresentava sinais e sintomas de hipertensão intracraniana, tinha um tumor na região da pineal. O segundo, feminino, 21 anos, tinha um tumor na região do aqueduto de Sylvius e apresentava cefaléia migranosa progressiva e diplopia. Ambos apresentavam hidrocefalia obstrutiva tratada com terceiroventriculostomia endoscópica e biópsia da lesão. Não foi feito tratamento adicional. Concluimos que os neurocitomas devem ser considerados no diagnóstico diferencial de tumores localizados na região da pineal e do aqueduto.

    Full Text Available Resumo: A Distrofia Muscular de Duchenne (DMD é uma doença genética de caráter recessivo que caracterizada por fraqueza muscular progressiva de cintura pélvica e escapular evoluindo para insuficiência respiratória e, ou cardíaca. O camundongo mdx é um modelo amplamente utilizado para estudos da DMD. Apesar do fenótipo destes animais serem mais suave, estes apresentam o principal músculo respiratório, o diafragma com morfologia e bioquímica semelhante à DMD humana, fato este que pode comprometer a função respiratória e consequentemente os pulmões. Foi realizado um estudo anatômico descritivo do parênquima pulmonar dos pulmões de 5 animais modelo mdx comparando estes com os pulmões de 5 camundongos BALB/C57 (Mus musculus. Os pulmões foram analisados macroscopicamente e através de microscopia de luz e eletrônica de varredura. Os achados sugerem que o modelo mdx apresenta morfologia pulmonar semelhante aos camundongos BALB/C57 e que seu uso deve ser cauteloso e criterioso em ensaios clínicos que aborde este órgão.

    2013-08-01

    Full Text Available As rugas são sulcos ou pregas cutâneas que se apresentam de forma progressiva pelo declínio da junção dermoepidérmica, em que ocorre um distúrbio nos componentes do tecido conjuntivo. O colágeno torna-se mais rígido e a elastina perde a sua elasticidade natural com a redução do número de fibras elásticas e de outros componentes do tecido. O objetivo do estudo foi verificar osefeitos da aplicação de eletrolifting em rugas. É um relato de caso, com uma participante do sexo feminino, de 54 anos, com rugas estáticas em regiões frontal, orbital, bucal e nasolabial, que foi submetida a seis sessões de aplicação de eletrolifting, com intervalo de sete dias entre cada intervenção, os resultados foram avaliados pela análise fotográfica e questionário de satisfação pessoal. Observou-se melhora no aspecto da face, atenuação das linhas de expressão, e como consequência melhora da auto-estima e aparência estética. A aplicação de eletrolifting mostrou resultados satisfatórios.

  9. Síndrome de Sjögren: revisão de literatura e acompanhamento de um caso clínico

    Freitas Tarsila M. C.

    2004-01-01

    Full Text Available A síndrome de Sjögren é uma doença inflamatória sistêmica, de natureza auto-imune, caracterizada pela infiltração linfocitária progressiva de vários órgãos exócrinos e não exócrinos. Acomete preferencialmente as glândulas salivares e lacrimais determinando prejuízo estrutural e disfunção secretória destes órgãos. A produção de auto-anticorpos e a hipergamaglobulinemia policlonal indicam que anormalidades na imunidade humoral desempenham um papel importante na patogenia desta afecção e o seu diagnóstico é baseado na combinação de vários achados clínicos e laboratoriais. A proposta deste trabalho é apresentar um caso clínico de síndrome de Sjögren enfatizando a sua importância clínica e a necessidade do diagnóstico precoce na tentativa de melhorar a qualidade de vida dos pacientes acometidos.

  15. Abordagem diagnóstica da tosse crônica em pacientes não-tabagistas: diagnostic approach

    Jacomelli Márcia

    2003-01-01

    Full Text Available A tosse, como mecanismo fisiológico, tem fundamental importância na remoção das secreções respiratórias, constituindo, assim, um dos mecanismos de defesa pulmonar. No entanto, os quadros de tosse crônica constituem uma das principais causas de procura por assistência médica no mundo, o que ressalta o significado da correta identificação e tratamento dos fatores desencadeantes e/ou perpetuadores. Dentre os vários fatores relacionados aos quadros de tosse crônica, alguns assumem papel de relevada importância, tais como o refluxo gastroesofágico, a rinorréia posterior ou a asma, já que, isolada ou conjuntamente, constituem cerca de 95% das causas. O passo fundamental para o sucesso terapêutico nos quadros de tosse crônica é uma abordagem diagnóstica racional, que investigue a tosse crônica de maneira progressiva, permitindo, assim, a instituição do tratamento de forma mais custo-efetiva. Para isso, a proposta de um algoritmo a ser seguido serve como base para essa investigação inicial.

  16. Selenium content of tissues in Finnish infants and adults with various diseases, and studies on the effects of selenium supplementation in neuronal ceroid lipofuscinosis patients

    Westermarck, T.

    1977-01-01

    A low blood selenium level has previously been observed in healthy inhabitants of Finland. In this study even lower blood selenium values were observed in patients with acrodermatitis enteropathica, dystrophia musculorum progressiva (Duchenne), infantile and juvenile type of neuronal ceroid lipofuscinosis (NCL), severe mental retardation caused by various factors, and myocardial infarction. The selenium content of the brain, heart, kidney and liver in patients of different ages was also determined. The highest selenium level was found in the kidney. The mean liver selenium concentrations in stillborn, premature and full-term neonates were 1.11 plus minus 0.23 (8), 1.21 plus minus 0.17 (12) and 0.93 plus minus 0.16 μg/g dry weight (12) respectively (the number of subjects in parentheses). The selenium values are considerably higher than those in infants of from one to nine months of age and adults, whose liver selenium values were 0.58 plus minus 0.21 (8) and 0.67 plus minus 0.08 μg/g dry weight (8) respectively. The vitamin E levels of serum in patients with NCL, as well as in subjects with severe mental retardation (controls), were low compared with values in healthy normal subjects. Sodium selenite supplementation in patients with NCL produced at least a transitory improvement without causing any toxic effects during one year of administration. (author)

  17. A Escola de Governo: do berço à idade adulta

    FÁBIO KONDER COMPARATO

    Full Text Available resumo A Escola de Governo foi criada em São Paulo em 1990, com o objetivo de explicar o mecanismo de funcionamento de nossas instituições políticas. Seu objetivo não é meramente teórico, mas sim prático; ou seja, colaborar para a progressiva correção dos rumos de nossa vida política, em obediência aos princípios fundamentais da República, da Democracia e do Estado de Direito. Para alcançar esse objetivo, os cursos ministrados na Escola focalizam principalmente os dois fatores estruturantes de toda sociedade política; a saber, a estrutura hierarquizada do poder e a mentalidade coletiva dominante. Procura-se mostrar que, desde sempre, tem havido uma dupla vigência do ordenamento jurídico nesse particular: por trás do direito oficial, em geral copiado do estrangeiro e praticamente inaplicado, existe efetivamente um outro direito, todo submetido aos comandos de uma oligarquia binária, composta dos potentados econômicos privados e dos grandes agentes estatais.

  18. La vida invisible ed El séptimo velo di Juan Manuel de Prada: quando echi e geometrie divengono formule

    Simone Cattaneo

    2012-01-01

    Full Text Available Il presente articolo vorrebbe mostrare, soffermandosi soprattutto sull’analisi dei romanzi La vida invisible (2003 e El séptimo velo (2007, come la traiettoria letteraria di Juan Manuel de Prada sia nel fondo frutto di una progressiva sedimentazione di tic stilistici, metafore, similitudini, immagini e personaggi che ricorrono sistematicamente nei suoi libri, finendo per dare vita a universi chiusi, retti su archetipi che, con la loro fissità, offuscano il brillante stile barocco dell’autore e mettono a nudo una certa serialità delle vicende narrate. The aim of this article is to show, through the analysis of the novels La vida invisible and El séptimo velo, how the whole literary work of Juan Manuel de Prada –one of the most acclaimed spanish writers born in the Seventies– is based on a progressive sedimentation of stylistic devices, metaphors, similes, images and characters. As a consequence, the literary worlds that he creates in his books are claustrophobic and rely on archetypes that, because of their shared traits, undermine the brilliance of his baroque style and reveal some repetitiveness in the elaboration of plots and situations.
