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)

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.

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".

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

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.

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.

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

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 autosomal dominant severe musculoskeletal disease characterized by extensive new bone formation within soft connective tissues and unique skeletal malformations of the big toes which represent a birth hallmark for the disease. 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.

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

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

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

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

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

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.

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).

CASE DESCRIPTION: A 10-year-old female patient that has developed, since the age of 4, progressive stiffness of the joints and spine and ossification of soft tissues, often associated with trauma. The hallux valgus deviation of both toes was present from birth. X-ray showed the presence of heterotopic ossification. COMMENTS: This disease is likely to be diagnosed with the resources available in primary health care, since it is based on clinical findings. Currently, there is no cure for this disease, but high doses of corticosteroids and the use of nonsteroidal anti-inflammatory drugs, which are available in the primary care level, may limit the development of new calcifications and mitigate the pain, improving the quality of life of these patients.

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.

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

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

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

A 53-year-old woman had extraskeletal osteosarcoma that developed from a soft tissue bony mass present on the volar aspect of the left wrist for 4 years. 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.)

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

Gallium uptake in myositis ossificans. Potential pitfalls in diagnosis

International Nuclear Information System (INIS)

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

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)

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

Directory of Open Access Journals (Sweden)

Nishio Jun

2010-08-01

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.

Myositis ossificans and the three-phase bone scan

International Nuclear Information System (INIS)

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

Magnetic resonance imaging of myositis ossificans: Analysis of seven cases

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

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)

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.

Myositis ossificans in hemophilia

Energy Technology Data Exchange (ETDEWEB)

Vas, W.; Cockshott, W.P.; Martin, R.F.; Pai, M.K.; Walker, I.

1981-10-01

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.

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.

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.

Myositis ossificans with atypical clinical, radiographic, or pathologic findings

International Nuclear Information System (INIS)

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 circumscripta of the masseter muscle.

Science.gov (United States)

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.

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.

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.)

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.

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

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)

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

International Nuclear Information System (INIS)

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

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.)

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.

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)

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

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

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.)

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.

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. Th...

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.

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

International Nuclear Information System (INIS)

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

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.

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.)

Regional blood flow in experimental myositis ossificans

International Nuclear Information System (INIS)

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)

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.)

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.

Heterotopic ossification revisited.

Science.gov (United States)

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.

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 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.

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.

Myositis ossificans traumatica in young children: report of three cases and review of the literature

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.)

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.

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

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.

Molecular, Phenotypic Aspects and Therapeutic Horizons of Rare Genetic Bone Disorders

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.

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

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 A mielomalácia hemorrágica progressiva (MHP é uma afecção rara e fatal, em que ocorre necrose aguda isquêmica e progressiva do parênquima da medula espinhal, levando à liquefação da mesma. Pode ocorrer após extrusão do disco intervertebral, trauma medular ou embolismo fibrocartilaginoso. Este estudo teve como objetivo avaliar casos de mielomalácia hemorrágica progressiva em cães atendidos no Hospital Veterinário da Universidade Estadual de Londrina entre os anos 2000 e 2011, realizando-se a análise dos prontuários de atendimento e acompanhamento dos casos. Os animais do presente estudo atendiam a alguns critérios de inclusão, como histórico de paraplegia com sinais de neurônio motor superior, piora dos sinais progredindo para tetraplegia flácida, alterações clínicas progressivas e/ou alterações nos exames complementares. Foram analisados os aspectos epidemiológicos (raça, idade e sexo, clínicos (evolução dos sinais clínicos e neurológicos, laboratoriais (análise do líquido cefalorraquidiano, radiográficos (radiografias simples e contrastadas e o tempo decorrido desde o início dos sinais clínicos até óbito ou eutanásia.

Em sete cães a causa da MHP foi a doença do disco intervertebral toracolombar, em um cão a causa foi o trauma medular, em dois cães a MHP foi decorrente de linfoma e em quatro cães a causa provável foi doença de disco intervertebral. Alterações na análise do líquido cerebroespinhal, na mielografia e na evolução dos sinais clínicos e neurológicos foram extremamente importantes para diagnosticar a MHP. Seis animais progrediram para tetraplegia e quatro cães já apresentavam tetraplegia flácida no atendimento inicial. Em

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.

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.

Full Text Available A hemiatrofia facial progressiva (HFP é doença esporádica de etiologia não esclarecida, caracterizada por progressiva atrofia e deformação de um dos lados da face. 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.

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.

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

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.

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

Deficiência progressiva dos hormônios adeno-hipofisários após radioterapia em adultos Progressive pituitary hormone deficiency following radiation therapy in adults

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.

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)

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.

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.

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

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.

The objectives of this study were to describe the main features of patients with PML and estimate its frequency among AIDS patients with central nervous system (CNS opportunistic diseases admitted to the Instituto de Infectologia Emílio Ribas, São Paulo, Brazil, from April 2003 to April 2004. A retrospective and descriptive study was performed. Twelve (6% cases of PML were identified among 219 patients with neurological diseases. The median age of patients with PML was 36 years and nine (75% were men. Nine (75% patients were not on antiretroviral therapy at admission. The most common clinical manifestations were: focal weakness (75%, speech disturbances (58%, visual disturbances (42%, cognitive dysfunction (42%, and impaired coordination (42%. The median CD4+ T-cell count was 45 cells/µL. Eight (67% of 12 patients were laboratory-confirmed with PML and four (33% were possible cases. Eleven (92% presented classic PML and only one case had immune reconstitution inflammatory syndrome (IRIS-related PML. In four (33% patients, PML was the first AIDS-defining illness. During hospitalization, three patients (25% died as a result of nosocomial pneumonia and nine (75% were discharged to home. Cases of PML were only exceeded by cases of cerebral toxoplasmosis, cryptococcal meningoencephalitis, and CNS tuberculosis, the three more frequent neurologic opportunistic infections in Brazil. The results of this study suggest that PML is not an uncommon HIV-related neurologic disorder in a referral center in Brazil.Existe informação limitada sobre a presença da leucoencefalopatia multifocal progressiva (LEMP em pacientes com aids no Brasil.

Full Text Available 【Abstract】Objective: The treatment of multi-fragmentary, intraarticular fractures of the distal humerus is difficult, even in young patients with bone of good quality. Small distal fragment, diminished bone mineral quality and increased trauma-associated joint destruction make stable joint reconstruction more problematic. The anatomically preshaped locking plates allow angular stable fixation for these complex fractures. We evaluated functional results of patients treated with open reduction and internal fixation with distal humerus locking plates for complex distal hu-merus fractures. Methods: Forty-three consecutive patients with ar-ticular fractures of the distal humerus were treated by open reduction and internal fixation with AO distal humerus plate system and locking reconstruction plates. Forty patients were available for the final outcome analysis. According to AO/ASIF classification, there were 2 cases of type A2, 4 cases of type A3, 1 case of type B1, 1 case of type B2, 14 cases of type C1, 7 cases of type C2 and 11 cases of type C3. Open reduction with triceps splitting technique was used in all patients. The clinical and radiographic follow-up was performed and outcome measures included pain assessment, range of motion, and Mayo elbow performance score. Results: Forty patients were available for the final outcome analysis. There were 29 males and 11 females with an average age of 38.4 years (18-73 years. Clinical and ra-diological consolidation of the fracture was observed in all cases at an average of 11.6 weeks (9-14 weeks. The average follow-up was 12 months (10-18 months. Using the Mayo elbow performance score the results obtained were graded as excellent or good results in 33 patients (82.5%. One pa-tient had superficial infection, and 4 had myositis ossificans. There were no cases of primary malposition or secondary displacement, implant failure or ulnar neuropathy. Conclusion: Anatomically preshaped distal humerus locking

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.

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.

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)

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

Extraarticular bony ankylosis in a child with supracondylar fracture of humerus

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.

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.

F. Soares Pires

2013-01-01

Full Text Available Introduction: Idiopathic Pulmonary Fibrosis (IPF is the most common disease in the subgroup of idiopathic interstitial pneumonias. It is inevitably associated to a bad prognosis, although assuming a highly variable clinical course. Methods: Patients with IPF, observed at Interstitial Lung Diseases outpatient clinic of Centro Hospitalar de São João – Porto, Portugal, were identified and clinical, functional, radiological and bronchoalveolar lavage (BAL parameters were reviewed. Their clinical course and survival were analyzed in order to identify prognostic factors. Results: Eighty-one patients were included, with a mean age at diagnosis of 63.8 years old. At diagnosis, the main functional abnormalities were restrictive physiology, reduced lung diffusion and exercise capacity impairment. Clinical course was mainly slowly progressive (72.3%. Ten patients (13.2% had a rapid progression and 11 (14.5% patients had an acute exacerbation during the course of the disease. IPF's rapid progression was associated to a higher functional impairment at diagnosis, namely in what is related with Functional Vital Capacity (FVC and Total Lung Capacity (TLC. Median survival was 36 months. A significant difference in survival was observed among different types of clinical course – 41 months for slow progressors and 9 months for rapid progressors. Lower levels of FVC, TLC, six-minute walk test (6MWT distance and rest PaO2, and higher BAL neutrophil count were associated with poorer survival in univariate analysis. Conclusion: The analysis of this group of IPF patients confirms two clearly different phenotypes, slow and rapid progressors. Those phenotypes seem to have different presentations and a remarkably different natural history. These results could mean different physiopathologic pathways, which could implicate different therapeutic approaches.

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.

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

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.

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.

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

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.

Full text: Introduction: SPECT-CT study allows the precise correlation between functional and morphological data on the same image. Methods: Whole body bone scan (WBBS) is a diagnostic modality still firmly established as a valuable tool to assess skeleton abnormalities. CT is an imaging method for characterizing destruction of the bone spongy lesions, their consolidation or calcium accumulation. This fact allows differentiation of the osteolytic metastases from the osteosclerotic and mixed lesions and also from degenerative ones. Whole body bone scan followed by SPECT-CT scanning increases the accuracy of the study and potentially accelerates the diagnosis of the patient based on a single imaging session. This is especially important in cancer patients. Results and discussion: After retrospectively review of WBBS and SPECT-CT fused images 141 bone lesions in 89 pts were analyzed The skeletal findings with previously uncertain character were classified as definitely benign, indeterminate or definitely malignant. 1. 47 (33%) of all lesions in 36 pts could be correlated with benign degenerative findings on SPECT-CT images. 5 (3%) lesions in 3 of these pts were indeterminate on the SPECT-CT images. They were localized in the area of articulation parts and corpus of the thoracic vertebra and ribs. After additional MRT examination and 6 months follow-up these changes were considered degenerative: osteopathy changes and presence of spondyloarthrosis and osteochondrosis; compression fractures due to advanced osteoporosis. These pts were with prolonged chormono/chemotherapy; chronic inflammatory disease of the coxofemoral articulation, coxarthrosis, aseptic necrosis of the femoral head and postoperative sacroiliitis; post-traumatic fractures or surgical intervention; hyperplastic degenerative lesions in the skeleton and asymmetrical pelvic bone structures due to M.

Aneurysmal bone cyst is a benign proliferative tumefaction of bone. Histologic similarities indicate a kinship among classic aneurysmal bone cysts, essentially 'solid' proliferative lesions in bones; giant cell reparative granulomas of the jaws, at the base of the skull, and in the small bones of the hands and feet; skeletal lesions of hyperparathyroidism; and even pseudosarcomatous myositis ossificans, proliferative myositis, and proliferative fasciitis.

Introduction: Heterotopic ossification occurs when bone develops in tissues which usually don’t undergo ossification. Heterotopic mesenteric ossification, also known as intra-abdominal myositis ossificans, is a rare and benign form of ossification, usually related with previous abdominal surgery or trauma. Presentation of cases: We report two cases of heterotopic ossification both after multiple abdominal surgeries, with intraoperative findings of mesenteric and abdominal wall ossification...

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.)

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.

MÉTODOS: Seis pacientes com idade entre 26 e 38 anos foram submetidos ao tratamento com crosslinking após implante de anel de Ferrara. Cinco pacientes receberam 2 segmentos de anel e um paciente recebeu um segmento. Depois de 4 a 55 meses os pacientes foram submetidos a aplicação do "crosslinking" com ultra-violeta de acordo com o protocolo estabelecido por Seiler & cols. RESULTADOS: Quatro olhos apresentaram alteração progressiva da refração e 2 apresentaram refração sem alteração progressiva. A topografia mostrou queda acentuada da curvatura e o estudo da lâmpada de fenda mostrou anel em boa profundidade durante um ano de pós-operatório em 100% dos olhos. A microscopia especular não mostrou alteração significativa e a acuidade visual se mostrou semelhante ao pré-operatório. CONCLUSÃO: O crosslinking poderá ajudar a manter ceratocones estáveis, não-somente nos casos de progressão, mas também nos cones evolutivos com implante de anel.PURPOSE: To describe our experience with crosslinking after Ferrara ring implant for better vision and corneal stabilization.

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.

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.

Full Text Available 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.

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.

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. (author)

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.

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

Directory of Open Access Journals (Sweden)

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.

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.)

Full Text Available Adrenoleukodystrophy (X-ALD is an X-linked recessively inherited peroxisomal disorder, phenotypically heterogeneous, characterized by progressive white-matter demyelination of the central nervous system and adrenocortical insufficiency. We investigated 15 male X-ALD patients varying in age from 7 to 39, diagnosed among 108 suspected patients referred for investigation. Plasma levels of very long chain fatty acids (VLCFA were measured at our laboratory using gas chromatography (GC. Eleven cases of childhood X-ALD and four cases of adrenomyeloneuropathy (AMN were diagnosed. Adrenal leukodystrophy insufficiency and limb weakness were the most frequent symptoms, appearing in 12, 8 and 6 of the patients, respectively. Physician awareness of X-ALD seems inadequate to judge by age at diagnosis and lengthy interval between the start of symptoms and diagnosis. This is the first published series of Brazilian patients with X-ALD. We determined signs and symptoms relevant for diagnosis, as early identification seems important for treatment outcome. In addition, diagnosis identifies carriers, who could benefit from genetic counselling and prenatal diagnosis.Adrenoleucodistrofia (X-ALD é uma desordem peroxissomal com padrão de herança ligada ao X, fenotipicamente heterogênea, caracterizada por uma progressiva desmielinização da substância branca do sistema nervoso central e por insuficiência adrenal. Foram investigados por nós 15 pacientes do sexo masculino com sinais clínicos sugestivos de X-ALD, com idade entre 7 e 39 anos, diagnosticados entre 108 pacientes encaminhados para investigação por suspeita clínica. Os níveis plasmáticos dos ácidos graxos de cadeia muito longa (VLCFA foram dosados em nosso laboratório através de cromatografia gasosa (GC.

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.

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.

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.)

Anesthetic management of two patients with alkaptonuric ochronosis for total knee arthroplasty

2018-05-01

Full Text Available The current case report describes two cases of alkaptonuric ochronosis for anesthetic management. Alkaptonuria is a rare genetic orphan disease of tyrosine metabolism characterized by an accumulation of homogentisic acid in cartilage and connective tissues. Patients present most commonly for orthopedic joint surgery due to progressive arthropathy that can be misdiagnosed many a times. However respiratory, airway, cardiovascular and genitourinary systems complications can occur with age progressing. Restricted range of motion of cervical spine may lead to difficulty with airway management. In addition, degenerative changes and stiffness of lumbar spine due to ochronosis would make neuraxial blockade challenging. Although this inherited condition is extremely rare, anesthesiologists should be aware of its existence and prepare for management of potential challenging problems. This report highlights special care and precautions that need to be taken during anesthetic management. Resumo: Este relato descreve o manejo anestésico em dois casos de ocronose alcaptonúrica. Alcaptonúria é uma doença genética rara do metabolismo de tirosina caracterizada por acúmulo de ácido homogentísico em cartilagem e tecidos conjuntivos. Os pacientes geralmente recorrem à cirurgia ortopédica devido à artropatia progressiva que, muitas vezes, pode ser diagnosticada incorretamente. No entanto, complicações das vias respiratórias, cardiovasculares e geniturinárias podem ocorrer com o avanço da idade. A restrição de mobilidade da coluna cervical pode levar ao manejo difícil das vias aéreas. Além disso, as alterações degenerativas e a rigidez da coluna lombar devido à ocronose podem tornar o bloqueio neuroaxial um desafio. Embora essa condição hereditária seja extremamente rara, os anestesiologistas devem estar cientes de sua existência e se prepararem para o manejo de potenciais problemas desafiadores.

Full Text Available A doença arterial periférica faz parte de um grupo de patologias vasculares que evolui de forma lenta e progressiva. A proposta deste artigo foi avaliar, por meio de revisão bibliográfica, os possíveis benefícios da eletroestimulação crônica como tratamento coadjuvante para pacientes arteriopatas. De acordo com a literatura analisada, concluímos que a eletroestimulação é capaz de provocar alterações importantes no perfil metabólico das fibras musculares, convertendo-as do tipo II para o tipo I, o que induz o crescimento capilar, a densidade capilar e o suprimento de oxigênio. Desta forma, este recurso terapêutico aumenta a capacidade aeróbica oxidativa e a resistência à fadiga dos músculos isquêmicos. Assim, a eletroestimulação é mais um recurso terapêutico capaz de melhorar a habilidade para caminhar destes pacientes, diminuindo gastos com cirurgias de revascularização e complicações maiores.Peripheral arterial disease is included in a group of vascular diseases whose evolution is slow and progressive. This article aimed at performing a literature review to evaluate the benefits of chronic electrostimulation as adjuvant treatment for arteriopathic patients. Based on the literature, we concluded that electrostimulation can generate important changes in the metabolic profile of muscle fibers, switching them from type II to type I, which leads to capillary increase, capillary density and suppression of oxygen. Therefore, this therapeutic resource increases aerobic oxidative capacity and ischemic muscle resistance to fatigue. Thus, electrostimulation is another therapeutic option able to improve these patients' walking ability, reducing expenses related to revascularization surgeries and major complications.

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.)

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.

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.

Full Text Available JUSTIFICATIVA E OBJETIVOS: O primeiro caso de proteinose alveolar pulmonar (PAP foi descrito por Rose em 1958, mas ainda é um distúrbio raro. PAP é caracterizada pela deposição de material lipoproteico secundário ao processamento anormal de surfactantes pelos macrófagos. Os pacientes podem ter dispneia progressiva e tosse, às vezes acompanhadas pelo agravamento da hipóxia, e seu curso pode variar de deterioração progressiva a melhora espontânea. Muitas terapias foram usadas, incluindo antibióticos, drenagem postural e ventilação com pressão positiva intermitente com acetilcisteína, heparina e soro fisiológico em aerossol. Atualmente, a base do tratamento é a lavagem pulmonar total (LPT. A LPT, embora seja geralmente bem-tolerada, pode estar associada a algumas complicações. RELATO DE CASO: Relatamos um caso de PAP grave durante o procedimento anestésico e as complicações no manejo da proteinose alveolar pulmonar em um paciente que havia sido submetido a múltiplas e alternadas lavagens de um dos pulmões ao longo de sete anos (os últimos três em nosso hospital, com melhora dos sintomas depois de cada tratamento.

2003-01-01

Full Text Available Hipertensão pulmonar primária é uma doença rara, progressiva e com alta mortalidade, cujo tratamento baseia-se em medicações de alto custo e pouco disponíveis em nosso meio. O sildenafil é um vasodilatador de fácil administração por via oral, com indicação primária para disfunção erétil e que recentemente tem sido descrito como opção terapêutica para a hipertensão pulmonar primária. Relata-se o caso de uma paciente de 21 anos com diagnóstico de hipertensão pulmonar primária, que apresentou piora abrupta da saturação de oxigênio, com abertura do forame oval e shunt direita-esquerda, evidenciados ao ecocardiograma. Foi introduzido sildenafil na dose de 225mg/dia com melhora progressiva da oxigenação e reversão do shunt após 40 dias. Os autores acreditam que o sildenafil seja uma opção no tratamento da hipertensão pulmonar primária, embora estudos clínicos que comprovem sua segurança e eficácia ainda sejam necessários.

Full Text Available O sucesso recente no desenvolvimento de uma prótese eletrônica coclear para surdos estimulou vários grupos de cientistas ao desenvolvimento de próteses visuais. A maioria dos protótipos de próteses visuais está baseada em estimulação elétrica neuronal em diferentes localizações do sistema visual até o sistema nervoso central. Atualmente os esforços estão concentrados em três localizações de implantes visuais: retina, nervo óptico e córtex. Implantes de retina e do nervo óptico têm o potencial de restabelecer a visão em pacientes com degenerações retinianas progressivas por meio de estimulação elétrica de neurônios do sistema visual. Próteses corticais podem beneficiar um número maior de pacientes cegos devido à sua localização mais posterior no sistema visual. Apesar dos grandes avanços, torna-se ainda necessária a elucidação de questões importantes na avaliação do funcionamento, em longo prazo, dos vários implantes eletrônicos para cegos, em estudo. Neste artigo analisamos os motivos que justificam o início dos experimentos nas três posições mencionadas e os desafios advindos de tal decisão.Recent success in the development of a prosthesis for the deaf patient encouraged several groups of scientists to develop and investigate a visual prosthesis. Visual prosthesis are based on neuronal electrical stimulation at different locations along the visual pathways, and three localizations of visual prosthesis are being researched, retina, optic nerve, and cortex. Retina and optic nerve implants may restore vision in patients with progressive retinal degenerations by means of electrical stimulation of visual pathway neurons. Cortex prosthesis may restore vision in a greater number of blind patients due to the more posterior location in the visual pathway. While major advances have been made in the field of visual prosthesis for the blind, a number of key questions remain to render a visual prosthesis

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

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.

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.)

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.

Background: Patients with chronic injuries of the proximal hamstring can develop significant impairment because of weakness of the hamstring muscles, sciatic nerve compression from scar formation, or myositis ossificans. Purpose: To describe the surgical outcomes of patients with chronic injury of the proximal hamstrings who were treated with hamstring repair and sciatic neurolysis supplemented with nerve wrapping with acellular dermal matrix. Study Design: Retrospective case series; Level of evidence, 4. Methods: Fifteen consecutive patients with a diagnosis of chronic complete proximal hamstring rupture or chronic ischial tuberosity apophyseal avulsion fracture (mean age, 39.67 years; range, 14-69 years) were treated with proximal hamstring repair and sciatic neurolysis supplemented with nerve wrapping with acellular dermal matrix. Nine patients had preoperative sciatica, and 6 did not. Retrospective chart review recorded clinical outcomes measured by the degree of pain relief, the rate of return to activities, and associated postoperative complications. Results: All 15 patients were followed in the postoperative period for an average of 16.6 months. Postoperatively, there were 4 cases of transient sciatic nerve neurapraxia. Four patients (26%) required postoperative betamethasone sodium phosphate (Celestone Soluspan) injectable suspension USP 6 mg/mL. Among the 9 patients with preoperative sciatica, 6 (66%) had a good or excellent outcome and were able to return to their respective activities/sports; 3 (33%) had persistent chronic pain. One of these had persistent sciatic neuropathy that required 2 surgical reexplorations and scar excision after development of recurrent extraneural scar formation. Among the 6 without preoperative sciatica, 100% had a good or excellent outcomes and 83% returned to their respective activities/sports. Better outcomes were observed in younger patients, as the 3 cases of persistent chronic sciatic pain were in patients older than 45

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 A disacusia neurossensorial imunomediada (DNSI é caracterizada geralmente por uma disacusia neurossensorial bilateral, progressiva e assimétrica, acompanhada ou não por outros sintomas da orelha interna. Três pacientes com DNSI cujo quadro clínico e audiométrico eram sugestivos de doença auto-imune, e apresentaram resposta positiva à terapia imunossupressora ou pesquisa positiva de anticorpo anti hsp-70 68kD, foram estudados com relação às características clínicas, testes diagnósticos, alternativas terapêuticas e evolução da doença. Dois pacientes apresentaram quadro de disacusia neurossensorial rapidamente progressiva, associado a quadro vestibular, e outro, quadro de surdez súbita unilateral. Nenhum paciente apresentou positividade às provas reumatológicas, e apenas um paciente apresentou aumento na velocidade de hemossedimentação. Nenhum paciente obteve resposta adequada sustentada à corticoterapia, mas dois deles melhoraram com outras terapias imunossupressoras. O diagnóstico da DNSI é clínico e baseado na resposta positiva ao teste terapêutico com imunossupressores. A pesquisa de anticorpo anti-hsp70 de 68 kD pelo Western Blot é o único exame laboratorial específico para seu diagnóstico, possuindo sensibilidade de 42% e especificidade de 90%. Apenas 1 paciente apresentou positividade para este teste e não respondeu à terapia imunossupressora. Os dois pacientes com teste negativo responderam satisfatoriamente ao tratamento. A baixa sensibilidade do Western Blot e seu alto custo dificultam sua difusa utilização em nosso meio. A introdução precoce do tratamento é de suma importância por auxiliar no diagnóstico e por proporcionar um melhor prognóstico auditivo.The immunomediated sensorineural hearing loss (ISHL is characterized as an asymmetric and progressive sensorineural hearing loss.

Lopez, Liurka V; Rodriguez, Michael G; Siegal, Gene P; Wei, Shi

2017-11-01

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.

Angiography of primary bone tumors

International Nuclear Information System (INIS)

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.

Suplementação de antioxidantes: enfoque em queimados Antioxidant supplementation: focusing on burned patients

Full Text Available Na queimadura, os radicais livres são produzidos durante a reposição de fluídos, alterando numerosos componentes, como os ácidos nucléicos, os lipídios e as proteínas. Sendo assim, se, por um lado, essa restauração do fluxo sanguíneo é, em geral, necessária para recuperar a função celular normal, por outro lado a reintrodução do sangue oxigenado nos tecidos isquêmicos contribui para uma produção excessiva de radicais livres derivados do oxigênio, exacerbando a lesão mediada pela isquemia. O papel dos neutrófilos ativados na célula após a queimadura também tem recebido atenção especial. A partir do sistema NADPH oxidase os neutrófilos aderidos podem produzir uma explosão de radical superóxido, produzindo um dano tecidual importante. A queimadura, além de aumentar a produção de radicais livres, também é capaz de impedir os mecanismos de defesa antioxidante, submetendo o paciente queimado ao estresse oxidativo, o qual se constitui em fator perpetuante da resposta inflamatória sistêmica, levando à piora progressiva do estado metabólico. Com esses dados, objetiva-se revisar os principais estudos com a suplementação de antioxidantes em pacientes críticos, com ênfase em pacientes queimados, e descrever os possíveis benefícios dessa intervenção.In burn injuries, free radicals are produced during fluid replacement, altering multiple components of the organism such as nucleic acids, lipids and proteins. Thus, if on the one hand restoring blood flow is generally necessary to recover normal cell function, on the other hand oxygen reperfusion into ischemic tissues triggers massive production of oxygen free radicals, therefore further exacerbating ischemic injury. The role of neutrophiles activated in the cell after burns has also received special attention. By means of the NADPH-oxidase system, adherent neutrophiles may release superoxide radicals inflicting major tissue damage. The burn injury not only

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.

Diagnóstico diferencial das distrofias musculares com referência especial às alterações enzimáticas

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

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.

Pitfalls in the MR diagnosis of primary malignant bone tumors; Pitfalls in der MR-Diagnostik primaer maligner Knochentumoren

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

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.

Full Text Available In this retrospective (1980-1998 study, we have analyzed clinico-demographically, from the records of the University Hospital of Fortaleza (Brazil, a group of 87 patients showing signs and symptoms of motor neuron diseases (MNDs. Their diagnosis was determined clinically and laboratorially. The WFN criteria were used for amyotrophic lateral sclerosis (ALS diagnosis. The clinico-demographic analysis of the 87 cases of MNDs showed that 4 were diagnosed as spinal muscular atrophy (SMA, 5 cases as ALS subsets: 2 as progressive bulbar paralysis (PBP, 2 as progressive muscular atrophy (PMA and 1 as monomelic amyotrophy (MA, and 78 cases of ALS. The latter comprised 51 males and 27 females, with a mean age of 42.02 years. They were sub-divided into 4 groups according to age: from 15 to 29 years (n= 17, 30 to 39 years (n= 18, 40 to 69 years (n= 39 and 70 to 78 years (n= 4. From the 78 ALS patients, 76 were of the classic sporadic form whilst only 2 were of the familial form. The analysis of the 87 patients with MNDs from the University Hospital of Fortaleza showed a predominance of ALS patients, with a high number of cases of juvenile and early onset adult sporadic ALS.Neste estudo retrospectivo (1980-1998, analisamos clínico-demograficamente, a partir dos prontuários do Hospital Universitário de Fortaleza (Brasil, um grupo de 87 pacientes que apresentavam sinais e sintomas de doenças do neurônio motor (DNMs. Eles foram diagnosticados clinicamente, e através de exames complementares.

Full Text Available OBJETIVO: Correlacionar os parâmetros tomográficos com os de função pulmonar em portadores de silicose, bem como comparar os resultados da tomografia computadorizada de alta resolução (TCAR com os da radiografia de tórax. MÉTODOS: Foi realizado um estudo de corte transversal, em que foram avaliados 44 pacientes não-tabagistas e sem história pregressa de tuberculose. As radiografias foram classificadas de acordo com a proposta da Organização Internacional do Trabalho. Utilizando um sistema de escore semiquantitativo, os seguintes achados na TCAR foram quantificados: extensão total do envolvimento pulmonar, opacidades parenquimatosas e enfisema. Foram realizados espirometria, oscilações forçadas, avaliação dos volumes pulmonares pela técnica de diluição com hélio e medida da diffusing capacity of the lung for carbon monoxide (DLCO, capacidade de difusão do monóxido de carbono. RESULTADOS: Dos 44 pacientes estudados, 41 eram homens, com média de idade de 48,4 anos. Na análise comparativa, 4 pacientes classificados na categoria 0 pela radiografia foram reclassificados na categoria 1 pela TCAR e, enquanto a radiografia diagnosticou 23 casos de fibrose maciça progressiva, a TCAR estabeleceu esse diagnóstico em 33 doentes. Para o escore de opacidades, as maiores correlações foram observadas com as medidas de fluxo, DLCO e complacência. Já o enfisema correlacionou-se negativamente com as medidas de volume, DLCO e fluxo. Nesta amostra com predomínio de grandes opacidades (75% dos indivíduos, a deterioração da função pulmonar associou-se com a extensão das alterações estruturais. CONCLUSÕES: Na silicose, a TCAR é superior à radiografia tanto na detecção precoce da doença quanto na identificação de fibrose maciça progressiva.OBJECTIVE: To correlate tomographic findings with pulmonary function findings, as well as to compare chest X-ray findings with high resolution computed tomography (HRCT findings, in

Full Text Available We added hydrotherapy to 50 patients with spinal muscular atrophy (SMA who were being treated with individual conventional physiotherapy. Hydrotherapy was performed at an approximate temperature of 30 degrees Celsius, twice a week, for thirty minutes in children and for forty-five minutes in adults during a 2-year period. The outcome derived from this combined modality of treatment was rated according to physiotherapeutic evaluations, the MMT (Manual Muscular Test, and the Barthel Ladder. Patients were reevaluated at 2-month intervals. After two years of ongoing treatment, we were able to observe that the deformities in hip, knee and foot were progressive in all SMA Type II patients, and in some Type III. Muscle strength stabilized in most SMA Type III patients, and improved in some. MMT was not done in SMA Type II. In all patients we were able to detect an improvement in the Barthel Ladder scale. This study suggests that a measurable improvement in the quality of daily living may be obtained in patients with SMA Types II and III subjected to conventional physiotherapy when associated with hydrotherapy.A hidroterapia foi realizada em SO pacientes com atrofia muscular espinhal, os quais foram também tratados com fisioterapia individual convencional. O tratamento hidroterápico foi realizado em piscina aquecida numa temperatura de aproximadamente 30° Celsius, duas vezes por semana, durante 30 minutos em crianças e 45 minutos em adultos num período de dois anos. Os benefícios deste tipo de tratamento foram avaliados de acordo com a evolução clínica, o MMT(Teste de Força Muscular e a Escala de Barthel. Os pacientes foram reavaliados a cada dois meses. Após dois anos de tratamento nós observamos que as deformidades nos quadris, joelhos e pés foram progressivas em todos os pacientes do Tipo II e em alguns do Tipo III. Houve estabilização da força muscular na maioria dos pacientes com SMA Tipo III, e melhora da força em alguns; nos

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.

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.)

To discuss the value of surgical hip dislocation approach in the treatment of femoral head fracture. A retrospectively analysis was made on the clinical data of 15 patients with femoral head fractures treated through surgical hip dislocation approach between January 2010 and February 2013. There were 11 men and 4 women with an average age of 30.8 years (range, 15-63 years). The causes included traffic accident injury in 9 cases, falling injury from height in 5 cases, and sports injury in 1 case. According to Pipkin typing, 2 cases were rated as type I, 7 cases as type II, 1 case as type III, and 5 cases as type IV. The interval of injury and operation was 2-10 days (mean, 4.1 days). Reduction was performed in 10 patients within 6 hours after injury, and then bone traction was given for 4-6 weeks except 5 patients who received reduction in the other hospital. Primary healing of incision was obtained in all patients after surgery without complications of dislocation and lower limbs deep venous thrombosis. The mean follow-up time was 29.9 months (range, 25-36 months). During follow-up, there was no infection, breakage of internal fixation, or nonunion of femoral greater trochanter fracture. In 3 patients having necrosis of the femoral head, 2 had no obvious symptoms [staging as IIa and IIb respectively according to Association Research Circulation Osseous (ARCO) staging system], and 1 (stage IIIb) had nonunion of the femoral neck fracture, who underwent total hip arthroplasty (THA). In 4 patients having myositis ossificans (2 cases of grade I, 1 case of grade II, and 1 case of grade III based on Brooker grading), no treatment was given in 3 cases and the focus was removed during THA in 1 case. According to the Thompson-Epstein scale at last follow-up, the results were excellent in 9 cases, good in 3 cases, fair in 1 case, and poor in 2 cases, and the excellent and good rate was 80%.

Full Text Available A síndroma hepatopulmonar é uma complicação importante da doença hepática crónica, ocorrendo em 16-24% dos doentes. É caracterizada por aumento do gradiente alveolocapilar com ou sem hipoxemia resultante de vasodilatação intrapulmonar. O curso da doença é progressivo e associado a aumento da morbilidade e mortalidade. Não existe tratamento médico eficaz, sendo o transplante hepático a opção terapêutica prioritária. Como exemplo desta patologia, os autores apresentam o caso clínico de um doente, sexo masculino, 39 anos, enviado à consulta de Pneumologia com informação de policitemia secundária e dispneia progressiva para esforços de média intensidade e cuja investigação permitiu identificar uma síndroma hepatopulmonar.Hepatopulmonary syndrome is an important complication of chronic liver disease occurring in 16 24% of patients. It is characterized by an increase in alveolar-capillary gradient, with or without hypoxemia, due to intrapulmonary vasodilatation. The course of the disease is progressive and associated with increased morbidity and mortality. There is no effective medical treatment and liver transplant is a priority. To exemplify the authors present the case of a 39 year-old male patient sent to the Pulmonology outpatient clinic and presenting with secondary polycythemia and progressive exertional dyspnoea. Clinical investigation identified a hepatopulmonary syndrome.

Three main childhood forms can be established on the basis of age of onset, clinical course, and ultrastructural morphology: infantile (INCL, late infantile (LINCL, and juvenile (JNCL. Several variant subtypes have been described. Genetic and biochemical analysis are helping to better understand, diagnose and classify these disorders. We report on clinical, neurophysiological, neuroradiological, and morphological data from 17 patients with different forms (infantile, late infantile, and juvenile of neuronal ceroid lipofuscinoses (NCL evaluated at Hospital de Clínicas de Porto Alegre, Southern Brazil, during 6 years (1992-1997. Seven cases were infantile; 5 were late infantile; and 5 were juvenile NCL. Gender ratio was male:female, 11:6. Age at presentation varied from 2-24 months for INCL; 2,5 to 5 years for LINCL ; and 4-10 years for the JNCL cases. Seizures (6 patients and psychomotor retardation (1 patient were the initial symptoms in the INCL group. All the patients in the group of LINCL had the usual findings. JNCL patients manifested different initial symptoms, although tending to follow a similar clinical picture within familial cases. Epidemiological data on the prevalence of NCLs in Brazil are not available, we expect this series of cases to contribute to further research in our population.As lipofuscinoses ceroides neuronais (LCN constituem um grupo de desordens neurodegenerativas, progressivas e de origem genética.

Full Text Available BACKGROUND: Esophagectomy presents the highest rate of postoperative pulmonary complications among all types of upper abdominal surgery. The benefits of chest physical therapy in patients undergoing upper abdominal surgery have been shown by many studies; however, its specific effect in patients receiving esophagectomy has been seldom investigated. OBJECTIVES: This study aimed to compare the frequency of respiratory complications in patients undergoing esophagectomy receiving chest physical therapy compared to no treatment. METHODS: 70 consecutive patients were evaluated retrospectively and allocated to two groups: control group (CG=no physical therapy; n=30 and chest physical therapy group (PTG; n=40. Patients received chest physical therapy which includes lung re-expansion and airway clearance maneuvers. They were not submitted to either noninvasive ventilation or exercises with devices that generate airways positive pressure. All patients were instructed to early mobilization. Information about pre-operative and respiratory complications were collected. Statistic analysis to compare the frequency of respiratory complications was performed by the Z test. The significance level was set to 5%. RESULTS: Patients in the CG and PTG were similar in terms of age, BMI, smoking and drinking status, malignant diseases, surgical and anesthesia duration and types of esophagectomy (p>0.05. Our results show that patients received chest physical therapy after esophagectomy had a lower frequency of respiratory complications (15% vs. 37%, pCONTEXTUALIZAÇÃO: A esofagectomia apresenta a maior taxa de complicações pulmonares pós-operatórias dentre as cirurgias abdominais altas.

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.

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.

Full Text Available L’intento dell’articolo è quello di fornire alcune riflessioni sul processo di costruzione dell’identità europea a partire da una considerazione critica del discorso istituzionale sullo straniero non comunitario. 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’.

Recurrent purpura due to alcohol-related Schamberg's disease and its association with serum immunoglobulins: a longitudinal observation of a heavy drinker.

Bonnet, Udo; Selle, Claudia; Isbruch, Katrin; Isbruch, Katrin

2016-10-31

It is unusual for purpura to emerge as a result of drinking alcohol. Such a peculiarity was observed in a 55-year-old man with a 30-year history of heavy alcohol use. The Caucasian patient was studied for 11 years during several detoxification treatments. During the last 2 years of that period, purpuric rashes were newly observed. The asymptomatic purpura was limited to both lower limbs, self-limiting with abstinence, and reoccurring swiftly with alcohol relapse. This sequence was observed six times, suggesting a causative role of alcohol or its metabolites. A skin biopsy revealed histological features of purpura pigmentosa progressiva (termed Schamberg's disease). Additionally, alcoholic fatty liver disease markedly elevated serum immunoglobulins (immunoglobulin A and immunoglobulin E), activated T-lymphocytes, and increased C-reactive protein. In addition, moderate combined (cellular and humoral) immunodeficiency was found. Unlike the patient's immunoglobulin A level, his serum immunoglobulin E level fell in the first days of abstinence, which corresponded to the time of purpura decline. Systemic vasculitis and clotting disorders were excluded. The benign character of the purpura was supported by missing circulating immune complexes or complement activation. An alcohol provocation test with vinegar was followed by the development of fresh "cayenne pepper" spots characteristic of Schamberg's disease. This case report demonstrates that Schamberg's disease can be strongly related to alcohol intake, in our patient most likely as a late complication of severe alcoholism with alcoholic liver disease. Immunologic disturbances thereby acquired could have constituted a basis for a hypersensitivity-like reaction after ingestion of alcohol. Schamberg's disease induction by vinegar may point to an involvement of acetate, a metabolite of ethanol.

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.

Unexpected death of a ventilator-dependent amyotrophic lateral sclerosis patient

Directory of Open Access Journals (Sweden)

M. di Paolo

2013-07-01

Full Text Available Background: Amyotrophic lateral sclerosis (ALS is a fatal, progressive, neurodegenerative disease and most patients affected die of respiratory compromise and/or pneumonia within 2–3 years of diagnosis. As ALS progresses, ventilator assistance is required. In the end stages of the disease, patients suffer from respiratory failure and may become ventilator-dependent. Deaths due to malfunction of mechanical ventilators are reported but there are very few forensic autopsy records. We report the case of a 69-year-old ALS female ventilator-dependent, trachostomised patient who was found dead by her husband, with the ventilator in “stand-by” mode. Method: A forensic autopsy was performed. Samples of internal organs were taken for histological and toxicological examination. The ventilator internal memory was also analysed and tested in order to find possible malfunction. Results: Gross examination did not reveal any sign of trauma but showed brain and lung congestion. Pulmonary histological examination revealed thickening of peribronchial interstitial space, alveolar over-distension, break of inter-alveolar walls and diffuse alveolar haemorrhages. Focal microhemorrhages were also detected in other organs. Analysis of the ventilator internal memory showed that during the night of death, there had been several voltage drops. Specific tests revealed malfunction of the internal battery which was unable to provide the necessary voltage, as a consequence the ventilator switched off, stopping ventilation. Battery malfunction reduced the volume of the ventilator alarm, which was not heard by the caregiver. Conclusion: Histological pattern, with acute pulmonary emphysema and focal polivisceral haemorrhages, is strongly suggestive of a death due to “acute” asphyxia. The authors also discuss the need for strict supervision and follow up of these ventilatory dependent patients and their devices. Resumo: Introdução: A Esclerose

Full Text Available Tay-Sachs disease is an autosomal recessive disorder of sphingolipid metabolism, caused by enzime hexosaminidase A deficiency that leads to an accumulation of GM2 in neurocytes which results in progressive loss of neurological function. The accumulation of lipid in retinal ganglion cells that leads to a chalk-white appearance of the fundus called "cherry red spot" is the hallmark of Tay-Sachs disease. It is also seen in others neurometabolic diseases as well as in central retinal artery occlusion. This case reports a child with Tay-Sachs disease in a family with four previous similar deaths without diagnostic.Tay-Sachs é uma doença autossômica recessiva, caracterizada pela deficiência da enzima hexosaminidase A levando ao acúmulo de esfingolipídios (GM2 em células neuronais que resulta em uma perda progressiva da função neurológica.

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

Science.gov (United States)

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.

Pitfalls in the MR diagnosis of primary malignant bone tumors

International Nuclear Information System (INIS)

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)

Patient participation in patient safety still missing: Patient safety experts' views.

The aim of this study was to elicit patient safety experts' views of patient participation in promoting patient safety. Data were collected between September and December in 2014 via an electronic semi-structured questionnaire and interviews with Finnish patient safety experts (n = 21), then analysed using inductive content analysis. Patient safety experts regarded patients as having a crucial role in promoting patient safety. They generally deemed the level of patient safety as 'acceptable' in their organizations, but reported that patient participation in their own safety varied, and did not always meet national standards. Management of patient safety incidents differed between organizations. Experts also suggested that patient safety training should be increased in both basic and continuing education programmes for healthcare professionals. Patient participation in patient safety is still lacking in clinical practice and systematic actions are needed to create a safety culture in which patients are seen as equal partners in the promotion of high-quality and safe care. © 2016 John Wiley & Sons Australia, Ltd.

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.

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 OBJETIVOS: avaliar as características do sêmen humano preservado a +4ºC e a -196ºC por 24 h e determinar a técnica ideal para utilização em procedimentos específicos. MÉTODOS: amostras de sêmen de 24 voluntários foram analisadas após a coleta e divididas em duas alíquotas, uma resfriada em a +4ºC e outra congelada a -196ºC. As amostras foram mantidas em baixas temperaturas por 24 h e então em temperatura ambiente por 30 minutos (T1, capacitadas (T2 e incubadas a +37ºC por 90 minutos (T3, sendo avaliadas quanto à concentração e motilidade progressiva em T1, T2 e T3. Para análise dos resultados obtidos com as duas diferentes técnicas foi utilizado o Modelo Linear Geral e para análise dos dados obtidos com a mesma técnica, em dois diferentes momentos de observação, foi utilizado o teste de Wilcoxon (a de 5% e p0,05 quanto à concentração, motilidade e NTEM entre as técnicas nos três momentos de observação. 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.

Acute care patients discuss the patient role in patient safety.

2011-01-01

Patient safety has been a highly researched topic in health care since the year 2000. One strategy for improving patient safety has been to encourage patients to take an active role in their safety during their health care experiences. However, little research has shed light on how patients view their roles. This study attempted to address this deficit by inductively exploring the results of a qualitative study in which patients reported their ideas about what they believe their roles should be. Patients with an overnight stay in the previous 90 days at one of three hospitals were surveyed using a mailing methodology. Of 1,040 respondents, 491 provided an open-ended response regarding what they believe the patient role should be. Qualitative analysis found several prominent themes. The largest proportion of responses (23%) suggested that patients should follow instructions given by care providers. Other prominent themes were that patients should ask questions and become informed about their conditions and treatments, and many implied that they should expect competent care. Our results suggest that patients believe they should be able to trust that they are being provided competent care, as opposed to assuming a leadership role in their safety. Our results suggest that engaging patients in safety efforts may be complex, requiring a variety of strategies. Managers must provide environments conducive to staff and patient interactions to support patients in this effort. Different types of patients may require different engagement strategies.

Full Text Available Amiloidose refere-se à deposição extracelular e progressiva de proteínas fibrilares patogênicas com características microscópicas e ultra-estruturais similares. A amiloidose pode ser sistêmica ou localizada. Descrevemos três pacientes que desenvolveram amiloidose intra-oral, sendo que dois casos manifestaram amiloidose localizada e o outro caso apresentou amiloidose sistêmica com acometimento de língua. Nos três casos, o exame histopatológico evidenciou depósitos de amilóide, os quais foram confirmados pela coloração de vermelho-congo. A ultra-estrutura mostrou material fibrilar compatível com amilóide. Apesar de infreqüente, a cavidade bucal pode ser um importante local de acometimento de amiloidose.

The analysis was based on the constant comparison of the data, the progressive incorporation of subjects and triangulation among researchers and stomal therapy nurses. The software Atlas.ti was used. two main categories emerge: "Coping with the news about receiving a stoma" and "Meaning and experience of the new bodily reality". The informants' answer varies, showing situations that range from the natural acceptance of the process to resignation and rejection. The previous experiences of other family members, the possible reconstruction of the stoma or the type of illness act as conditioning factors. the coping with the news about the stoma is conditioned by the type of illness, although the normalization of the process is the trend observed in most informants. Nursing plays a fundamental role in the implementation of cognitive-behavioral interventions and other resources to promote the patients' autonomy in everything related to care for the stoma. descrever o enfrentamento de pessoas ostomizadas diante da notícia da realização do estoma, assim como analisar o significado e a vivência diante de sua nova realizada corporal. estudo qualitativo fenomenológico mediante entrevistas semiestruturadas com 21 personas ostomizadas.

Full Text Available As distrofias hereditárias de retina abrangem um amplo número de doenças caracterizadas por lenta e progressiva degeneração da retina. São o resultado de mutações em genes expressos em fotorreceptores e no epitélio pigmentado da retina. A herança pode ser autossômica dominante, autossômica recessiva, ligada ao X recessiva, digênica ou herança mitocondrial. Atualmente não há tratamento para essas doenças e os pacientes convivem com a perda progressiva da visão. O aconselhamento genético e o suporte para reabilitação têm indicação nestes casos. Pesquisas envolvendo a base molecular e genética dessas doenças está continuamente em expansão e ampliam as perspectivas para novas formas de tratamento. Dessa forma, a terapia gênica, que consiste na inserção de material genético exógeno em células de um indivíduo com finalidade terapêutica, tem sido a principal forma de tratamento para as distrofias hereditárias de retina. O olho é um órgão peculiar para a terapia gênica, pois é anatomicamente dividido em compartimentos, imunologicamente privilegiado e com meios transparentes. A maioria das doenças oculares tem defeitos em genes conhecidos. Além disso, há modelo animal bem caracterizado para algumas condições. Propostas para pesquisa clínica em terapia gênica nas degenerações retinianas hereditárias com defeito no gene RPE65, recentemente tiveram aprovação ética e os resultados preliminares obtidos trouxeram grandes expectativas na melhora da qualidade de vida dos pacientes.The inherited retinal dystrophies comprise a large number of disorders characterized by a slow and progressive retinal degeneration.

To report the personal experiences of patients undergoing awake craniotomy for brain tumor resection. We carried out a qualitative descriptive survey of patients` experiences with awake craniotomies for brain tumor resection. The survey was conducted through a standard questionnaire form after the patient was discharged from the hospital. Of the 9 patients who met the inclusion criteria and underwent awake craniotomy, 3 of those patients reported no recollection of the operation. Five patients had auditory recollections from the operation. Two-thirds (6/9) reported that they did not perceive pain. Five patients remembered the head clamp fixation, and 2 of those patients classified the pain from the clamp as moderate. None of the patients reported that the surgery was more difficult than anticipated. Awake craniotomy for surgical resection of brain tumors was well tolerated by patients. Most patients reported that they do not recall feeling pain during the operation. However, we feel that further work and exploration are needed in order to achieve better control of pain and discomfort during these types of operations.

Achieving patient satisfaction: resolving patient complaints.

Patients demand to be active participants on and partners with the health care team to design their care regimen. Patients bring unique perceptions and expectations and use these to evaluate service quality and satisfaction. If customer satisfaction is not achieved and a patient complaint results, staff must have the skills to respond and launch a service recovery program. Service recovery, when done with style and panache, can retain loyal customers. Achieving patient satisfaction and resolving patient complaints require commitment from top leadership and commitment from providers to dedicate the time to understand their patients' needs.

To elicit patient stakeholders' experience and perspectives about patient-centred care. Qualitative. A large urban healthcare system. Four patient stakeholders who are prostate cancer survivors. Experience and perspectives of patient stakeholders regarding patient-centred care and treatment decisions. Our patient stakeholders represented a diverse socio-demographic group. The patient stakeholders identified engagement and dialogue with physicians as crucial elements of patient-centred care model. The degree of patient-centred care was observed to be dependent on the situations. High severity conditions warranted a higher level of patient involvement, compared to mild conditions. They agreed that patient-centred care should not mean that patients can demand inappropriate treatments. An important attribute of patient-centred outcomes research model is the involvement of stakeholders. However, we have limited knowledge about the experience of patient stakeholders in patient-centred outcomes research. Our study indicates that patient stakeholders offer a unique perspective as researchers and policy-makers aim to precisely define patient-centred research and care.

Patient Involvement in Patient Safety: A Qualitative Study of Nursing Staff and Patient Perceptions.

Bishop, Andrea C; Macdonald, Marilyn

2017-06-01

The risk associated with receiving health care has called for an increased focus on the role of patients in helping to improve safety. Recent research has highlighted that patient involvement in patient safety practices may be influenced by patient perceptions of patient safety practices and the perceptions of their health care providers. The objective of this research was to describe patient involvement in patient safety practices by exploring patient and nursing staff perceptions of safety. Qualitative focus groups were conducted with a convenience sample of nursing staff and patients who had previously completed a patient safety survey in 2 tertiary hospital sites in Eastern Canada. Six focus groups (June 2011 to January 2012) were conducted and analyzed using inductive thematic analysis. Four themes were identified: (1) wanting control, (2) feeling connected, (3) encountering roadblocks, and (4) sharing responsibility for safety. Both patient and nursing staff participants highlighted the importance of building a personal connection as a precursor to ensuring that patients are involved in their care and safety. However, perceptions of provider stress and nursing staff workload often reduced the ability of the nursing staff and patient participants to connect with one another and promote involvement. Current strategies aimed at increasing patient awareness of patient safety may not be enough. The findings suggest that providing the context for interaction to occur between nursing staff and patients as well as targeted interventions aimed at increasing patient control may be needed to ensure patient involvement in patient safety.

Full Text Available We describe a patient who had difficulty in walking since toddling stage and presented proximal upper and lower member weakness which have evolved to a progressive limitation of neck and trunk flexure, compatible with rigid spine syndrome. The serum muscle enzymes were somewhat elevated and the electromyography showed a myopatic change. The muscle biopsy demonstrated an active and chronic myopathy. The DNA analysis through PCR did not display any abnormality for dystrophin gene. The dystrophin by immnofluorescence was present in all fibers, but some interruptions were found in the plasma membrane giving it the appearance of a rosary. The test for merosin was normal.Relatamos o caso de um paciente com dificuldade de marcha desde o início da deambulação, com fraqueza proximal de membros, evoluindo com limitação progressiva da flexão do pescoço e tronco, compatível com a síndrome da espinha rígida. As enzimas musculares séricas estavam moderadamente elevadas e a eletromiografia revelou padrão miopático. A biópsia muscular indicou miopatia crônica e ativa. A análise do DNA por PCR não demonstrou alterações no gene da distrofina. A imunofluorescência para distrofina foi positiva em todas as fibras, apresentando interrupções na membrana plasmática, semelhante a um rosário e o teste para merosina mostrou positividade.

Full Text Available The authors report a case of a 16-year-old man who presented progressive dyspnea. At that time the diagnosis of rheumatic fever with mitral valve involvement was performed. The bidimensional echocardiogram showed presence of mobile mass inside the left atrium. The tumor presented lobules, projecting into the left ventricle during the diastole and provoking turbulence. The patient underwent surgical resection with postoperative course needing re-operation for mitral valve replacement. Histopathology has proven that such tumor was a primary cardiac rhabdomyosarcoma and the early clinical diagnosis of rheumatic mitral valve disease was very difficult.Os autores reportam caso de jovem de 16 anos, o qual apresentou dispnéia progressiva.

However, not all physician-patient relationships follow the normal course and/or meet the natural ends. These abnormal relationships are not inconsequential in terms of numbers and/or their effects (short-term and long term on both patients and physicians. Every country has its own baggage in the wake of why, how and what about these abnormal ends to physician-patient relationships; however, the most common causes are the patients’ inability to pay their medical bills, the conflicting goals of physicians and their patients in regards to patients’ sufferings’ management and finally the behavioral issues (patients’ and/or physicians’ interfering these relationships.

Primary extraintestinal complications caused by Yersinia enterocolitica are extremely rare, especially in the form of skin and soft-tissue manifestations, and little is known about their clinical characteristics and treatments. We presented our case and reviewed past cases of primary skin and soft-tissue infections caused by Y enterocolitica. We report a case of primary cellulitis and cutaneous abscess caused by Y enterocolitica in an immunocompetent 70-year-old woman with keratodermia tylodes palmaris progressiva. She presented to an outpatient clinic with redness, swelling, and pain of the left ring finger and left upper arm without fever or gastrointestinal symptoms 3 days before admission. One day later, ulceration of the skin with exposed bone of the proximal interphalangeal joint of the left ring finger developed, and cefditoren pivoxil was described. However, she was admitted to our hospital due to deterioration of symptoms involving the left finger and upper arm. Cefazolin was initiated on admission, then changed to sulbactam/ampicillin and vancomycin with debridement of the left ring finger and drainage of the left upper arm abscess. Wound culture grew Y enterocolitica serotype O:8 and methicillin-sensitive Staphylococcus aureus. Blood cultures were negative and osteomyelitis was ruled out. Vancomycin was switched to ciprofloxacin, then skin and soft-tissue manifestations showed clear improvement within a few days. The patient received 14 days of ciprofloxacin and oral amoxicillin/clavulanate and has since shown no recurrence. We reviewed 12 cases of primary skin and soft-tissue infections caused by Y enterocolitica from the literature. In several past cases, portal entry involved failure of the skin barrier on distal body parts. Thereafter, infection might have spread to the regional lymph nodes from the ruptured skin. Y enterocolitica is typically resistant to aminopenicillins and narrow-spectrum cephalosporins. In most cases, these inefficient

For patient-oriented mobile health tools to contribute meaningfully to improving healthcare delivery, widespread acceptance and use of such tools by patients are critical. However, little is known about patients' attitudes toward using health technology and their willingness to share health data with providers. To investigate primary care patients' comfort sharing health information through mobile devices, and patients' awareness and use of patient portals. Patients (n=918) who visited one of 6 primary care clinics in the Northwest US completed a survey about health technology use, medical conditions, and demographics. More patients were comfortable sharing mobile health information with providers than having third parties store their information (62% vs 30%, Somers D=.33, phigher among patients with a chronic condition (AOR= 3.18, p=0.004). Comfort, awareness, and use of health technologies were variable. Practices introducing patient-facing health technologies should promote awareness, address concerns about data security, and provide education and training, especially to older adults and those with health literacy limitations. Patient-facing health technologies provide an opportunity for delivering scalable health education and self-management support, particularly for patients with chronic conditions who are already using patient portals.

ELBOW AND WRIST INJURIES IN SPORTS

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

Consumerism in health care defines patients as self-determined, rational customers. Yet, it is questionable whether vulnerable patients, such as the terminally ill, also fulfill these criteria. Vulnerable contexts and the patient's perspective on being a customer remain relatively unexplored. The present study addresses this research gap by analyzing terminally ill patients' views on being customers. To explore the ways in which patients in palliative care refer to themselves as patients/customers, and how the patients' concepts of self-determination are related to their attitudes toward the patient/customer role. Qualitative interviews were conducted. Data were analyzed in three steps: narrative analysis, thematic content analysis, and typology construction. Researchers recruited 25 patients via the Department of Palliative Care, University Medical Center Freiburg, Germany. In many ways, palliative patients contradict the image of a self-determined customer. The palliative patient role is characterized by the concept of relational self-determination rather than an unrestricted self-determination. Self-attribution as a customer still occurs when positively associated with a person-centered, individualized treatment. Thus, the customer and patient role overlap within the palliative care setting because of the focus on the individual. The idealized customer role cannot be arbitrarily applied to all medical fields. Palliative patients are dependent on the physician, regardless of whether the customer or patient role is preferred. Hence, self-determination must be understood in relational terms, and physicians must recognize their crucial role in promoting patients' self-determination in the context of shared decision-making.

ETHICAL MODELS OF PHYSICIAN--PATIENT RELATIONSHIP REVISITED WITH REGARD TO PATIENT AUTONOMY, VALUES AND PATIENT EDUCATION.

Science.gov (United States)

Borza, Liana Rada; Gavrilovici, Cristina; Stockman, René

2015-01-01

The present paper revisits the ethical models of patient--physician relationship from the perspective of patient autonomy and values. It seems that the four traditional models of physician--patient relationship proposed by Emanuel & Emanuel in 1992 closely link patient values and patient autonomy. On the other hand, their reinterpretation provided by Agarwal & Murinson twenty years later emphasizes the independent expression of values and autonomy in individual patients. Additionally, patient education has been assumed to join patient values and patient autonomy. Moreover, several authors have noted that, over the past few decades, patient autonomy has gradually replaced the paternalistic approach based on the premise that the physician knows what is best for the patient. Neither the paternalistic model of physician-patient relationship, nor the informative model is considered to be satisfactory, as the paternalistic model excludes patient values from decision making, while the informative model excludes physician values from decision making. However, the deliberative model of patient-physician interaction represents an adequate alternative to the two unsatisfactory approaches by promoting shared decision making between the physician and the patient. It has also been suggested that the deliberative model would be ideal for exercising patient autonomy in chronic care and that the ethical role of patient education would be to make the deliberative model applicable to chronic care. In this regard, studies have indicated that the use of decision support interventions might increase the deliberative capacity of chronic patients.

Patient involvement in patient safety: Protocol for developing an intervention using patient reports of organisational safety and patient incident reporting

Armitage Gerry

2011-05-01

Full Text Available Abstract Background Patients have the potential to provide a rich source of information on both organisational aspects of safety and patient safety incidents. This project aims to develop two patient safety interventions to promote organisational learning about safety - a patient measure of organisational safety (PMOS, and a patient incident reporting tool (PIRT - to help the NHS prevent patient safety incidents by learning more about when and why they occur. Methods To develop the PMOS 1 literature will be reviewed to identify similar measures and key contributory factors to error; 2 four patient focus groups will ascertain practicality and feasibility; 3 25 patient interviews will elicit approximately 60 items across 10 domains; 4 10 patient and clinician interviews will test acceptability and understanding. Qualitative data will be analysed using thematic content analysis. To develop the PIRT 1 individual and then combined patient and clinician focus groups will provide guidance for the development of three potential reporting tools; 2 nine wards across three hospital directorates will pilot each of the tools for three months. The best performing tool will be identified from the frequency, volume and quality of reports. The validity of both measures will be tested. 300 patients will be asked to complete the PMOS and PIRT during their stay in hospital. A sub-sample (N = 50 will complete the PMOS again one week later. Health professionals in participating wards will also be asked to complete the AHRQ safety culture questionnaire. Case notes for all patients will be reviewed. The psychometric properties of the PMOS will be assessed and a final valid and reliable version developed. Concurrent validity for the PIRT will be assessed by comparing reported incidents with those identified from case note review and the existing staff reporting scheme. In a subsequent study these tools will be used to provide information to wards/units about their

Pii, Kathrine Hoffmann

2015-01-01

Intro: This paper discusses a central professional dilemma in patient-centred education: on one hand the concern for ensuring patients autonomy and right to make their own decisions regarding their treatment and, on the other hand, a concern for getting patients to make the “right” decisions......-centredness is thus promoted as a way to organize health more effectively (in terms of cost and treatment outcomes) and as a way to ensure patients’ autonomy and fundamental right to make their own decisions regarding their treatment. Critical voices within social and nursing theory have however argued....... The paper shows that the programme’s attempt to facilitate that patients make their “own” decision is challenged by patients who understand the preventive programme in relational terms and even demand more intervention from the professionals in terms of expert advice, involvement, and discipline.

Meeker, B J

1994-04-01

Preoperative teaching is an important part of patient care and can prevent complications, as well as promote patient fulfillment during hospitalization. A study was conducted at Alton Ochsner Medical Foundation in New Orleans, LA, in 1989, to determine the impact of a preoperative teaching program on the incidence of postoperative atelectasis and patient satisfaction. Results showed no significant difference of postoperative complications and patient gratification after participating in a structured preoperative teaching program. As part of this study, it was identified that a patient evaluation tool for a preoperative teaching class needed to be developed. The phases of this process are explained in the following article.

Full Text Available Sara Misra, Blánaid Daly, Stephen Dunne, Brian Millar, Mark Packer, Koula AsimakopoulouDental Institute, King's College London, London, UKBackground: There is a lack of information about the extent to which patients recall key facts of dental consultations. Forgetting health advice undermines adherence with such instructions and is a potential problem. This study assessed the quantity and type of information recalled in a dental consultation, dentist–patient agreement over the contents of the consultation, and the relationship of such recall with patient satisfaction.Methods: Using a cross-sectional design, questionnaire data were obtained from patients recruited through a letter and presenting for a routine dental consultation. General issues discussed, specific information about oral health given, dentist-performed procedures, and agreed future actions were reported independently in writing, by patients and also by the treating dentist immediately postconsultation. Additionally, patients completed a dental visit satisfaction questionnaire.Results: Responses (n = 26, 55% response rate were content-analyzed, and data on the number and type of information that was recalled were obtained. Interrater reliability was established. Inferential testing showed differences in dentist–patient recall, dentist–patient agreement, and the association between patient recall and satisfaction. Dentists recalled more information than patients (P = 0.001. Dentists further reported giving more dental health education (P = 0.006 and discussing more future actions (P = 0.002 than patients actually remembered. Technical (eg, crowns/bridges rather than psychosocial (eg, pain/embarrassment issues were reported more often (P = 0.001 by both dentists and patients. Dentist–patient agreement over issues discussed and procedures performed was higher (kappa = 0.210–0.310 than dental health education agreement and agreed future actions (kappa = 0.060–0.110. There

Constructions of the patient in healthcare communications: six patient figures.

The purpose of this paper is to examine how strategic, patient-centred communication plays a part in the discursive management of expectations posed to patients and healthcare organizations. The paper provides an analysis of four documents collected as part of an ethnographic case study regarding "The Perspective of the Patient" - a Danish Hospital's patient-centred communication programme. Mapping methods inspired by Grounded Theory are used to qualify the analysis. The paper shows that strategic patient-centred communication addresses both a care-oriented approach to the patient and deploys market perceptions of patients. Market and care is seen as co-existing organizing modes that entail expectations to the patient. In the communication programme the patient is constructed in six information-seeking patient figures: affective patient; target group patient; citizen with rights; patient as a competent resource; user as active partner; and consumer. As a result, the patient-centred communication programme renders the patient as a flexible figure able to fit organizational demands of both care orientation and market concerns. This study contributes to qualitative research in organizational health communication by combining two subfields - patient-centredness and health communication - in an empirical study of how market and care are intertwined in a patient-centred communication programme. The argument goes beyond the prevalent prescriptive approaches to patient-centredness and healthcare communication, instead providing a critical analytical perspective on strategic communication and patient-centredness and showing how expectations are posed to both patient and organization.

Recently, the patient's role in preventing adverse events has been emphasized. Patients who are more knowledgeable about safety issues are more likely to engage in safety initiatives. Therefore, nurses need to develop techniques and tools that increase patients' knowledge in preventing adverse events. For this reason, an educational smartphone application for patient safety called "Safe Patients" was developed through an iterative process involving a literature review, expert consultations, and pilot testing of the application. To determine the effect of "Safe Patients," it was implemented for patients in surgical units in a tertiary hospital in South Korea. The change in patients' knowledge about patient safety was measured using seven true/false questions developed in this study. A one-group pretest and posttest design was used, and a total of 123 of 190 possible participants were tested. The percentage of correct answers significantly increased from 64.5% to 75.8% (P effectively improve patients' knowledge of safety issues. This will ultimately empower patients to engage in safe practices and prevent adverse events related to surgery.

To investigate the baseline status of patients' awareness, knowledge, and attitudes to patient safety in China, and to determine the factors that influence patients' involvement in patient safety. We conducted a cross sectional survey using questionnaires adapted from recent studies on patient safety from outside China. The items included medical errors, infection, medication safety, and other aspects of patient safety. The questionnaire included 17 items and 5 domains. The survey was conducted between Jan. 2009 and Dec. 2010 involving 1000 patients from ten grade-A hospitals in seven provinces or cities in China. Most patients from the surgery departments completed the questionnaires voluntarily and anonymously. Five reviewers independently input the data into Microsoft Excel 2003, and the data were double-checked. Data were analyzed using SPSS 15.0 software for differences in the perceptions and attitudes of patients toward patient safety among different genders, ages, and regions. We distributed 1000 questionnaires and collected 959 completed questionnaires (response rate: 96%). Among the respondents, 58% of patients did not know what medical error is. Sixty-five percent of patients wanted disclosure of all medical errors. After errors occurred, 58% of patients wanted explanations of all possible harms that had resulted. Among 187 patients who had experienced medical errors, 83% of patients had sought appropriate legal action. About 52% of patients understood hospital infection, but 28% patients did not know that infections could occur in hospital. Seventy-eight percent of patients thought that medical staff should wash their hands before examining patients. More than half of the patients (68%) were willing to remind the staff of hygiene if they saw unsanitary conditions in a health clinic. Only 14% of patients knew the side effects of medications that they took. The majority of patients surveyed expressed willingness to contribute to patient safety, but their

This study aimed to (1) identify patient-controlled analgesia (PCA) attributes that negatively impact patient satisfaction and ability to control pain while using PCA and (2) obtain data on patient perceptions of new PCA design features. We conducted a prospective survey study of postoperative pain control among patients using a PCA device. The survey was designed to evaluate patient satisfaction with pain control, understanding of PCA, difficulties using PCA, lockout-period management, and evaluation of new PCA design features. A total of 350 eligible patients completed the survey (91%). Patients who had difficulties using PCA were less satisfied (P PCA. Forty-nine percent of patients reported not knowing if they would receive medicine when they pushed the PCA button, and of these, 22% believed that this uncertainty made their pain worse. The majority of patients preferred the proposed PCA design features for easier use, including a light on the button, making it easier to find (57%), and a PCA button that vibrates (55%) or lights up (70%), alerting the patient that the PCA pump is able to deliver more medicine. A majority of patients, irrespective of their satisfaction with PCA, preferred a new PCA design. Certain attributes of current PCA technology may negatively impact patient experience, and modifications could potentially address these concerns and improve patient outcomes.

Effective design of health information technology (HIT) for patient-centered care requires consideration of workflow from the patient's perspective, termed 'patient-oriented workflow.' This approach organizes the building blocks of work around the patients who are moving through the care system. Patient-oriented workflow complements the more familiar clinician-oriented workflow approaches, and offers several advantages, including the ability to capture simultaneous, cooperative work, which is essential in care delivery. Patient-oriented workflow models can also provide an understanding of healthcare work taking place in various formal and informal health settings in an integrated manner. We present two cases demonstrating the potential value of patient-oriented workflow models. Significant theoretical, methodological, and practical challenges must be met to ensure adoption of patient-oriented workflow models. Patient-oriented workflow models define meaningful system boundaries and can lead to HIT implementations that are more consistent with cooperative work and its emergent features.

The aim of this study was to explore cardiac patients' perception of patient-centred care. Despite patient's importance in the process of care, less attention has been paid to experiences and expectations of patients in definitions of patient-centred care. As patients are an important element in process of patient-centred care, organizing care programs according to their perceptions and expectations will lead to enhanced quality of care and greater patient satisfaction. This study is a descriptive qualitative study. Content analysis approach was performed for data analysis. Participants were 18 cardiac patients (10 women and 8 men) hospitalized in coronary care units of teaching hospitals affiliated to Tehran University of Medical Sciences. We collected the study data through conducting personal face-to-face semi-structured interviews. The participants' perceptions of patient-centred care fell into three main themes including managing patients uncertainty, providing care with more flexibility and establishing a therapeutic communication. The second theme consisted of two sub-themes: empathizing with patients and having the right to make independent decisions. Receiving patient-centred care is essential for cardiac patients. Attention to priorities and preferences of cardiac patients and making decisions accordingly is among effective strategies for achieving patient-centred care. Cardiac care unit nurses ought to be aware that in spite of technological developments and advances, it is still important to pay attention to patients' needs and expectations in order to achieve patient satisfaction. In planning care programs, they should consider accountability towards patients' needs, flexibility in process of care and establishing medical interactions as an effective strategy for improving quality of care. © 2014 British Association of Critical Care Nurses.

There have been studies on the patient-centeredness of medical students and physicians in South Korea, but no result has presented the patient-centered attitude of patients and doctors. So, this study intended to compare the attitudes of patients and doctors toward the roles that patients and physicians should play in the health care process. One hundred and fifteen doctors and 264 patients participated in this survey using a structured questionnaire, including sociodemographic data and Patient Practitioner Orientation Scale (PPOS). The PPOS comprises sharing (sharing information, take part in decision making) and caring (respecting one's feelings, interpersonal relationships) subscales. The PPOS scores of the doctors and patient were 3.02 and 3.20. In detail, the doctors' sharing and caring scores were and 3.02 and 3.48, and the those of patients were 3.14 and 3.12, respectively. This results are enough to demonstrate that patients are likely to be patient-centered with regard to sharing and that doctors tend to be patient-centered in terms of caring. The patients' desire to obtain medical information and take part in decision making (sharing) are greater than those of doctors. Doctors had more patient-centered attitude than patients in terms of respects for one's feelings and interpersonal relationships (caring).

Electronic patient portals give patients access to personal medical data, potentially creating opportunities to improve knowledge, self-efficacy, and engagement in healthcare. The combination of knowledge, self-efficacy, and engagement has been termed activation. Our objective was to assess the relationship between patient activation and outpatient use of a patient portal. Survey. A telephone survey was conducted with 180 patients who had been given access to a portal, 113 of whom used it and 67 of whom did not. The validated patient activation measure (PAM) was administered along with questions about demographics and behaviors. Portal users were no different from nonusers in patient activation. Portal users did have higher education level and more frequent Internet use, and were more likely to have precisely 2 prescription medications than to have more or fewer. Patients who chose to use an electronic patient portal were not more highly activated than nonusers, although they were more educated and more likely to be Internet users.

Patients are becoming increasingly active in their relationship with medical professionals. Their relationship with medical students needing to learn clinical skills, may be specially problematic if patients are not willing to accept their involvement in the medical team. To examine patient's perceptions of their relation with medical students and their agreement to let students be part of the treating team. Qualitative study using taped semi-structured interviews addressed to inpatients from one public and one private hospital in Chile. Both groups of patients acknowledged that students dedicated more time to them, but they expressed their preference to limit student's participation to clinical history taking and physical examination. They also expected them to be observers rather than actors. Patients from the private hospital emphasized that only one student per instructor should participate in their care. Patients from the public hospital were more compliant about student's participation. The right to refuse students' involvement in their care was clearly known by all patients from the private system and by most patients from the public hospital. Patients in Chilean public and private hospitals were in general positive regarding student's participation in their care. Students' clinical practice ought to strictly respect patients's rights, and patients should be considered volunteers who generously agree to cooperate with the education of medical students.

Patient satisfaction and positive patient outcomes in ambulatory anesthesia

Full Text Available Ushma Shah, David T Wong, Jean Wong Department of Anesthesia, Toronto Western Hospital, University Health Network, University of Toronto, Toronto, ON, Canada Abstract: Most surgeries in North America are performed on an ambulatory basis, reducing health care costs and increasing patient comfort. Patient satisfaction is an important outcome indicator of the quality of health care services incorporated by the American Society of Anesthesiologists (ASA. Patient satisfaction is a complex concept that is influenced by multiple factors. A patient's viewpoint and knowledge plays an influential role in patient satisfaction with ambulatory surgery. Medical optimization and psychological preparation of the patient plays a pivotal role in the success of ambulatory surgery. Postoperative pain, nausea, and vomiting are the most important symptoms for the patient and can be addressed by multimodal drug regimens. Shared decision making, patient–provider relationship, communication, and continuity of care form the main pillars of patient satisfaction. Various psychometrically developed instruments are available to measure patient satisfaction, such as the Iowa Satisfaction with Anesthesia Scale and Evaluation du Vecu de I'Anesthesie Generale, but none have been developed specifically for ambulatory surgery. The ASA has made recommendations for data collection for patient satisfaction surveys and emphasized the importance of reporting the data to the Anesthesia Quality Institute. Future research is warranted to develop a validated tool to measure patient satisfaction in ambulatory surgery. Keywords: patient, satisfaction, anesthesia, outcomes, questionnaire, perspectives

Patient participation in patient safety and nursing input - a systematic review.

2015-03-01

This systematic review aims to synthesise the existing research on how patients participate in patient safety initiatives. Ambiguities remain about how patients participate in routine measures designed to promote patient safety. Systematic review using integrative methods. Electronic databases were searched using keywords describing patient involvement, nursing input and patient safety initiatives to retrieve empirical research published between 2007 and 2013. Findings were synthesized using the theoretical domains of Vincent's framework for analysing risk and safety in clinical practice: "patient", "healthcare provider", "task", "work environment", "organisation & management". We identified 17 empirical research papers: four qualitative, one mixed-method and 12 quantitative designs. All 17 papers indicated that patients can participate in safety initiatives. Improving patient participation in patient safety necessitates considering the patient as a person, the nurse as healthcare provider, the task of participation and the clinical environment. Patients' knowledge, health conditions, beliefs and experiences influence their decisions to engage in patient safety initiatives. An important component of the management of long-term conditions is to ensure that patients have sufficient knowledge to participate. Healthcare providers may need further professional development in patient education and patient care management to promote patient involvement in patient safety, and ensure that patients understand that they are 'allowed' to inform nurses of adverse events or errors. A healthcare system characterised by patient-centredness and mutual acknowledgement will support patient participation in safety practices. Further research is required to improve international knowledge of patient participation in patient safety in different disciplines, contexts and cultures. Patients have a significant role to play in enhancing their own safety while receiving hospital care. This

To assess patients' and healthcare workers' (hcw) attitudes and experiences with a patient safety advisory, to investigate predictors for patients' safety-related behaviors and determinants for staff support for the advisory. Cross-sectional surveys of patients (n= 1053) and hcw (n= 275). Three Swiss hospitals. Patients who received the safety advisory and hcw caring for these patients. Patient safety advisory disseminated to patients at the study hospitals. Attitudes towards and experiences with the advisory. Hcw support for the intervention and patients' intentions to apply the recommendations were modelled using regression analyses. Patients (95%) and hcw (78%) agreed that hospitals should educate patients how to prevent errors. Hcw and patients' evaluations of the safety advisory were positive and followed a similar pattern. Patients' intentions to engage in safety were significantly predicted by behavioral control, subjective norms, attitudes, safety behaviors during hospitalization and experiences with taking action. Hcw support for the campaign was predicted by rating of the advisory (Odds ratio (OR) 3.4, confidence interval (CI) 1.8-6.1, Ppatients (OR 1.9, CI 1.1-3.3, P= 0.034) and experience of unpleasant situations (OR 0.6, CI 0.4-1.0, P= 0.035). The safety advisory was well accepted by patients and hcw. To be successful, the advisory should be accompanied by measures that target norms and barriers in patients, and support staff in dealing with difficult situations.

Patient information in radiooncology. Results of a patient survey

Schaefer, C.; Dietl, B.; Putnik, K.; Altmann, D.; Herbst, M.; Marienhagen, J.

2002-01-01

Background: As a result of increased interest and public demand, providing patients with adequate information about radiooncology has become more and more difficult for the doctor. Insufficient patient information can not only cause anxiety for the patient, but can also lead to legal action against the physician. In order to gain a deeper insight into our clinical practice of providing patient information, we developed a special questionnaire. We describe our first experiences in using this questionnaire at our institute. Patients and methods: We examine the amount of information and level of satisfaction, as well as the agreement of assessment between patient and physician after the provision of standard patient information before and at the end of radiotherapy. 51 consecutive patients were interviewed with a newly designed questionnaire. The first questioning with 13 items was carried out before radiotherapy and the second with ten items was done at the end of treatment. Sum scores for information and satisfaction were defined and agreement was measured by the weighted κ coefficient. Results: Global level of information and satisfaction was good, and a significant increase in information level and a significant decline in satisfaction were seen between questionnaire 1 and 2. Agreement between patient and physician was fair, for example intent of treatment resulted in a κ coefficient of 0.34, and poor for the doctor's role with a κ coefficient of -0.002. Only 52% of the patients who received palliative radiotherapy rated correctly the non-curative intent of treatment, whereas 86% of the patients who received curative radiotherapy made a correct statement. Before radiotherapy, emotional state was often both negatively and positively assessed by the patients. Conclusion: Our short questionnaire is simple and easy to understand. It provides insights into patient information with respect to assessment of the information, satisfaction level, and agreement between

Does patient satisfaction affect patient loyalty?

Science.gov (United States)

Kessler, Daniel P; Mylod, Deirdre

2011-01-01

This paper aims to investigate how patient satisfaction affects propensity to return, i.e. loyalty. Data from 678 hospitals were matched using three sources. Patient satisfaction data were obtained from Press Ganey Associates, a leading survey firm; process-based quality measures and hospital characteristics (such as ownership and teaching status) and geographic areas were obtained from the Centers for Medicare and Medicaid Services. The frequency with which end-of-life patients return to seek treatment at the same hospital was obtained from the Dartmouth Atlas. The study uses regression analysis to estimate satisfaction's effects on patient loyalty, while holding process-based quality measures and hospital and market characteristics constant. There is a statistically significant link between satisfaction and loyalty. Although satisfaction's effect overall is relatively small, contentment with certain hospitalization experience may be important. The link between satisfaction and loyalty is weaker for high-satisfaction hospitals, consistent with other studies in the marketing literature. RESEARCH LIMITATION/IMPLICATIONS: The US hospitals analyzed are not a random sample; the results are most applicable to large, non-profit teaching hospitals in competitive markets. Satisfaction ratings have business implications for healthcare providers and may be useful as a management tool for private and public purchasers. The paper is the first to show that patient satisfaction affects actual hospital choices in a large sample. Because patient satisfaction ratings are also correlated with other quality measures, the findings suggest a pathway through which individuals naturally gravitate toward higher-quality care.

The aim of this paper is to present our "Patient Keeper" application, which is a client-server medical application. "Patient Keeper" is designed to run on a mobile phone for the client application and on a PC for the server application using J2ME and JAVA2, respectively. This application can help doctors during visits to their patients in hospitals. The client application allows doctors to store on their mobile phones the results of their diagnoses and findings such as temperature, blood pressure, medications, analysis, etc., and send this information to the server via short message service (SMS) for storage in a database. The server can also respond to any request from the client and send the result via Bluetooth, infrared, or over the air. Experimental results showed a significant improvement of the healthcare delivery and reduction for in-patient stay.

The relationship between physician humility, physician-patient communication, and patient health.

Cultural portrayals of physicians suggest an unclear and even contradictory role for humility in the physician-patient relationship. Despite the social importance of humility, however, little empirical research has linked humility in physicians with patient outcomes or the characteristics of the doctor-patient visit. The present study investigated the relationship between physician humility, physician-patient communication, and patients' perceptions of their health during a planned medical visit. Primary care physician-patient interactions (297 patients across 100 physicians) were rated for the physician's humility and the effectiveness of the physician-patient communication. Additionally, patients reported their overall health and physicians and patients reported their satisfaction with the interaction. Within-physician fluctuations in physician humility and self-reported patient health positively predicted one another, and mean-level differences in physician humility predicted effective physician-patient communication, even when controlling for the patient's and physician's satisfaction with the visit and the physician's frustration with the patient. The results suggest that humble, rather than paternalistic or arrogant, physicians are most effective at working with their patients. Interventions to improve physician humility may promote better communication between health care providers and patients, and, in turn, better patient outcomes. Copyright © 2016 Elsevier Ireland Ltd.

Full Text Available O ensaio procura flagrar o surgimento de um segundo “momento de escritura” na obra Guimarães Rosa, delineado por um conjunto de textos publicados em periódicos entre Sagarana (1946 e os livros de 1956, Corpo de Baile e Grande Sertão: Veredas. A partir da análise de uma importante carta do autor e de um dos textos síntese do período, “Com o Vaqueiro Mariano”, procuramos compreender as linhas de força de uma nova inflexão da literatura rosiana caracterizada pelo combate aos problemas da “deficiência representativa” imanente ao contexto literário brasileiro e internacional e pela constituição progressiva de uma voz narrativa em primeira pessoa marcada pela dificuldade de narrar e por uma postura de adesão à sua matéria que, adquirindo concretude nos textos, precisa ser pensada em termos de alcance estético-ideológico.

Full Text Available O trabalho analisa as representações e os relatos da experiência com a menopausa contidos no site brasileiro da internet Menospausa - o site da mulher madura, no espaço de interatividade, procurando identificar aspectos do climatério/menopausa, da vivência deste processo e das ações de cuidados. Foram separadas as 48 postagens, das quais dez escolhidas e analisadas conforme o gênero de narrativas, classificadas segundo Michael Bury como: contingentes, progressivas, morais, épicas/heroicas e regressivas/trágicas. Conclui-se que, apesar de a menopausa portar sinais corporais comuns, as representações e experiências narradas sobre corpo, menopausa e cuidados dialogam com os saberes médico e não eruditos, são heterogêneas, não necessariamente negativas, e informadas pelo contexto sociocultural mais amplo de suas protagonistas, e, em particular, filtradas pelas características do site.

Full Text Available O internato médico tem gerado recorrente debate frente às transformações curriculares em andamento no País. A despeito das discussões, um modelo de internato consonante com essas mudanças ainda não foi consistentemente delineado. Neste ensaio, trazemos uma proposta de matriz estruturante para o internato médico. Propomos que o internato médico seja realizado durante os seis anos do curso, de forma longitudinal, tendo como eixo estruturante a clínica da Atenção Básica (AB. Esse modelo de "internato longitudinal" prevê a introdução progressiva na prática clínica, iniciando-se pela AB nos dois primeiros anos, acrescentando-se progressivamente os ambulatórios de especialidades, os estágios hospitalares e demais atividades práticas, alcançando-se, dessa forma, o rol de diversidade e complexidade previsto para o egresso da escola médica.

Patient-Centeredness as Physician Behavioral Adaptability to Patient Preferences.

Science.gov (United States)

Carrard, Valérie; Schmid Mast, Marianne; Jaunin-Stalder, Nicole; Junod Perron, Noëlle; Sommer, Johanna

2018-05-01

A physician who communicates in a patient-centered way is a physician who adapts his or her communication style to what each patient needs. In order to do so, the physician has to (1) accurately assess each patient's states and traits (interpersonal accuracy) and (2) possess a behavioral repertoire to choose from in order to actually adapt his or her behavior to different patients (behavioral adaptability). Physician behavioral adaptability describes the change in verbal or nonverbal behavior a physician shows when interacting with patients who have different preferences in terms of how the physician should interact with them. We hypothesized that physician behavioral adaptability to their patients' preferences would lead to better patient outcomes and that physician interpersonal accuracy was positively related to behavioral adaptability. To test these hypotheses, we recruited 61 physicians who completed an interpersonal accuracy test before being videotaped during four consultations with different patients. The 244 participating patients indicated their preferences for their physician's interaction style prior to the consultation and filled in a consultation outcomes questionnaire directly after the consultation. We coded the physician's verbal and nonverbal behavior for each of the consultations and compared it to the patients' preferences to obtain a measure of physician behavioral adaptability. Results partially confirmed our hypotheses in that female physicians who adapted their nonverbal (but not their verbal) behavior had patients who reported more positive consultation outcomes. Moreover, the more female physicians were accurate interpersonally, the more they showed verbal and nonverbal behavioral adaptability. For male physicians, more interpersonal accuracy was linked to less nonverbal adaptability.

Full Text Available Remote patient management (RPM offers renal health care providers and patients with end-stage kidney disease opportunities to embrace home dialysis therapies with greater confidence and the potential to obtain better clinical outcomes. Barriers and evidence required to increase adoption of RPM by the nephrology community need to be clearly defined. Ten health care providers from specialties including nephrology, cardiology, pediatrics, epidemiology, nursing, and health informatics with experience in home dialysis and the use of RPM systems gathered in Vienna, Austria to discuss opportunities for, barriers to, and system requirements of RPM as it applies to the home dialysis patient. Although improved outcomes and cost-effectiveness of RPM have been demonstrated in patients with diabetes mellitus and heart disease, only observational data on RPM have been gathered in patients on dialysis. The current review focused on RPM systems currently in use, on how RPM should be integrated into future care, and on the evidence needed for optimized implementation to improve clinical and economic outcomes. Randomized controlled trials and/or large observational studies could inform the most effective and economical use of RPM in home dialysis. These studies are needed to establish the value of existing and/or future RPM models among patients, policy makers, and health care providers.

Patient recall of treatment information is a key variable towards chronic disease (CD) management. It is unclear what communication and patient participation characteristics predict recall. To assess what aspects of doctor-patient communication predict patient recall of medication information. To describe lifestyle treatment recall, in CD primary care patients. Observational study within a RCT. Community-based primary care (PC) practices. Family physicians (n=18): practicing >5 years, with a CD patient caseload. Patients (n=159): >40 years old, English speaking, computer literate, off-target hypertension, type II diabetes and/or dyslipidaemia. Patient characteristics: age, education, number of CDs. Information characteristics: length of encounter, medication status, medication class. Communication variables: socio-emotional utterances, physician dominance and communication control scores and PACE (ask, check and express) utterances, measured by RIAS. Number of medication themes, dialogue and initiative measured by MEDICODE. Recall of CD, lifestyle treatment and medication information. Frequency of lifestyle discussions varied by topic. Patients recalled 43% (alcohol), 52% (diet) to 70% (exercise) of discussions. Two and a half of six possible medication themes were broached per medication discussion. Less than one was recalled. Discussing more themes, greater dialogue and patient initiative were significant predictors of improved medication information recall. Critical treatment information is infrequently exchanged. Active patient engagement and explicit conversations about medications are associated with improved treatment information recall in off-target CD patients followed in PC. Providers cannot take for granted that long-term off-target CD patients recall information. They need to encourage patient participation to improve recall of treatment information. © 2016 The Authors. Health Expectations Published by John Wiley & Sons Ltd.

Patient satisfaction with doctor-patient interactions is an indicator of physicians' competence. The satisfaction of diabetes patients is rarely studied in public diabetes clinics of Pakistan. Thus, this study aims to analyse the association between patient satisfaction and five dimensions of medical interaction: technical expertise, interpersonal aspects, communication, consultation time, and access/availability. A cross-sectional mixed methods study was conducted during July and August 2015 in the largest public diabetes outpatient clinic in Punjab province. We used the criterion sampling method to identify 1164 patients who: (i) were adult (18 years and above), (ii) had diabetes mellitus, (iii) had made at least three previous visits to the same clinic. The data was collected through face-to-face interviews. The structured part of the questionnaire was based on demographic characteristics and the Patient Satisfaction Questionnaire (PSQ-III). We translated the questionnaire into Urdu and pretested it with 25 patients in a similar context. Data storage and analysis were carried out using SPSS (version 22.0). Bivariate analyses and multinomial logistic regression model were used to generate the quantitative findings. Out of the 1164 eligible patients approached for interviews, 1095 patients completed the structured questionnaire and 186 respondents provided qualitative information in comments section. We conducted a thematic content analysis of qualitative responses in order to explain the quantitative findings. Demographic characteristics such as gender, education and occupation were significantly associated with the levels of patient satisfaction. The dimensions of doctor-patient interaction were significantly associated with patient satisfaction: technical expertise (OR = .87; 95% CI = .84-.91), interpersonal aspects (OR = .82; 95% CI = .77-.87), communication (OR = .83; 95% CI = .78-.89), time dimension (OR = .90; 95% CI = .81

Patient decision-making aids (PDMAs) help patients make informed healthcare decisions and improve patient satisfaction. The utility of PDMAs for patients considering treatments for urolithiasis has not yet been published. We report our experience using PDMAs developed at our institution in the outpatient clinical setting in patients considering a variety of treatment options for stones. Patients with radiographically confirmed urolithiasis were given PDMAs regarding treatment options for their stone(s) based on their clinical profile. We assessed patients' satisfaction, involvedness, and feeling of making a more informed decision with utilization of the PDMAs using a Likert Scale Questionnaire. Information was also collected regarding previous stone passage, history and type of surgical intervention for urolithiasis, and level of education. Patients (n = 43; 18 males, 23 females and two unknown) 53 +/- 14years old were included. Patients reported that they understood the advantages and disadvantages outlined in the PDMAs (97%), that the PDMAs helped them make a more informed decision (83%) and felt more involved in the decision making process (88%). Patients reported that the aids were presented in a balanced manner and used up-to-date scientific information (100%, 84% respectively). Finally, a majority of the patients prefer an expert's opinion when making a treatment decision (98%) with 73% of patients preferring to form their own opinion based on available information. Previous stone surgery was associated with patients feeling more involved with the decision making process (p = 0.0465). PDMAs have a promising role in shared decision-making in the setting of treatment options for nephrolithiasis.

There is increasing emphasis on the use of patient-reported experience data to assess practice performance, particularly in the setting of patient-centered medical homes. Yet we lack understanding of what organizational processes relate to patient experiences. Examine associations between organizational processes practices adopt to become PCMH and patient experiences with care. We analyzed visit data from patients (n=8356) at adult primary care practices (n=22) in a large health system. We evaluated the associations between practice organizational processes and patient experience using generalized estimating equations (GEE) with an exchangeable correlation structure to account for patient clustering by practice in multivariate models, adjusting for several practice-level and patient-level characteristics. We evaluated if these associations varied by race/ethnicity, insurance type, and the degree of patient comorbidity MEASURES:: Predictors include overall PCMH adoption and adoption of six organizational processes: access and communications, patient tracking and registry, care management, test referral tracking, quality improvement and external coordination. Primary outcome was overall patient experience. In our full sample, overall PCMH adoption score was not significantly associated with patient experience outcomes. However, among subpopulations with higher comorbidities, the overall PCMH adoption score was positively associated with overall patient experience measures [0.2 (0.06, 0.4); P=0.006]. Differences by race/ethnicity and insurance type in associations between specific organizational processes and patient experience were noted. Although some organizational processes relate to patients' experiences with care irrespective of the background of the patient, further efforts are needed to align practice efforts with patient experience.

Snyder, Claire F.; Jensen, Roxanne E.; Segal, Jodi B.; Wu, Albert W.

2013-01-01

Patient-centered outcomes research (PCOR) aims to improve care quality and patient outcomes by providing information that patients, clinicians, and family members need regarding treatment alternatives, and emphasizing patient input to inform the research process. PCOR capitalizes on available data sources and generates new evidence to provide timely and relevant information and can be conducted using prospective data collection, disease registries, electronic medical records, aggregated results from prior research, and administrative claims. Given PCOR’s emphasis on the patient perspective, methods to incorporate patient-reported outcomes (PROs) are critical. PROs are defined by the U.S. Food & Drug Administration as “Any report coming directly from patients… about a health condition and its treatment.” However, PROs have not routinely been collected in a way that facilitates their use in PCOR. Electronic medical records, disease registries, and administrative data have only rarely collected, or been linked to, PROs. Recent technological developments facilitate the electronic collection of PROs and linkage of PRO data, offering new opportunities for putting the patient perspective in PCOR. This paper describes the importance of and methods for using PROs for PCOR. We (1) define PROs; (2) identify how PROs can be used in PCOR, and the critical role of electronic data methods for facilitating the use of PRO data in PCOR; (3) outline the challenges and key unanswered questions that need to be addressed for the routine use of PROs in PCOR; and (4) discuss policy and research interventions to accelerate the integration of PROs with clinical data.

Prior research on the use of patients as teachers has focused on testing the effectiveness of this practice and exploring its benefits for students. However, very little is known about the added value of patient teaching and how it relates to patient-centred learning. The aim of this study was to explore whether there is added value in using patients as instructors in health professions education and, if there is, to examine how it is constituted. Group interviews were conducted with physiotherapy and occupational therapy students who had attended a 3-hour optional class entitled 'Thoughtful joint examination and respectful patient contact'. This class was delivered by patient-instructors (PIs), who were patients with rheumatism certified to teach. A semi-structured interview guide was used. Interviews continued until data saturation occurred (seven interviews). The interviews were recorded and transcribed verbatim. Data were analysed using content analysis. The main finding of this study is that PI sessions facilitate a learning environment in which the content matter is complemented by the provision of realism and individual perspectives on rheumatism, the pedagogical format is characterised by authenticity and intimacy in the style of instruction and feedback, and the PI-student relationship is characterised by balanced teacher-student power relations that support the legitimacy of learning and make space for the asking of questions and the making of mistakes. This study indicates that, in terms of power relations, the PI-student relationship differs from those between faculty teachers and students, and students and patients in the clinic. The formation of a professional identity by students may clash with the fulfilment of their learning tasks in the clinical environment. The study indicates that patient-centredness can be fostered in the PI-student relationship. This is probably supported by the absence of faculty staff involvement in PI teaching sessions

Communication during clinical encounters can be challenging with patients with communication disabilities. Physicians have the potential to positively affect the encounter by using communication strategies that engage the patient in patient-centered communication. We engaged patients and their physicians in defining their preferences for patient-centered communication strategies, then evaluated the use of the identified strategies during observed clinical encounters. We video-recorded 25 clinical encounters with persons with aphasia. All encounters were previously scheduled with community physicians and a companion was present. Following each encounter, physicians completed a brief questionnaire and the person with aphasia and his or her companion participated in a video elicitation interview. While many of the communication strategies identified and described by physicians, patients and companions were similar, patients and companions identified three additional key communication strategies. These strategies included (1) using visual aids, (2) writing down key words while speaking, and (3) using gestures. In the video recorded clinical encounters, no physicians wrote down key words while speaking and only one used a visual aid during the clinical encounter. The frequency with which physicians used gestures varied greatly, even within the same patient, suggesting the use of gestures was independent of patient or companion characteristics. To maximize patient-centered communication with patients with communication disabilities, physicians should use "disability-specific" communication strategies. Our study suggests that physicians should routinely ask patients and companions about communication preferences and then incorporate identified communication strategies into their communication style.

Patient delay and associated factors among breast cancer patients

International Nuclear Information System (INIS)

Khan, M.A.; Khan, M.I.; Andleeb, U.

2015-01-01

Objectives: To stratify patients into various stages, calculate average patient delay and study various causes of delay to presentation. Methodology: This was a one year hospital based cross sectional study at Khyber Teaching Hospital, using non probability consecutive sampling. A simplified staging was used for this study; Early (Stage I), Intermediate (Stage II, III), and Late (Stage IV). A patient was labelled delay when >3 months had elapsed between first symptom perception and first doctor consultation. Results: 80 patients were included with age 21-80 years (mean 45.28+-13.15). 80% of the patients were married, 76.3% (n=61/80) were poor with annual income of <500 US $, 85% of patients were illiterate. The participants from Rural and Urban areas were similar (37 % vs 31%); 15% were from Afghanistan. 80% patients presented with a delay of >3 months. Most common cause of delay was false symptom interpretation in 25.3% (n=17) patients. Conclusion: Late clinical presentation is because of lack of health education, unawareness, misconceptions about treatment and strong belief in traditional medicine resulting in advanced disease. This is worsened by poverty and unavailability of health care services especially in rural areas. (author)

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.

A large parosteal ossifying lipoma of lower limb encircling the femur

Science.gov (United States)

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

A randomised controlled trial was used to evaluate elective ambulatory orthopaedic surgery patients' emotions during internet-based patient education or face-to-face education with a nurse. The internet-based patient education was designed for this study and patients used websites individually based on their needs. Patients in the control group participated individually in face-to-face patient education with a nurse in the ambulatory surgery unit. The theoretical basis for both types of education was the same. Ambulatory orthopaedic surgery patients scored their emotions rather low at intervals throughout the whole surgical process, though their scores also changed during the surgical process. Emotion scores did not decrease after patient education. No differences in patients' emotions were found to result from either of the two different patient education methods.

Janine W.Y. Kee

2018-06-01

Full Text Available Purpose: Despite communication skills training in medical school, junior doctors continue to demonstrate poor patient-doctor communication skills, where patient unhappiness from the encounter often manifests as patient complaints. We sought to identify crucial communication skills that should be incorporated in the communications curriculum by learning from patient complaints, to explore how the communication lapses occur. Method: 38 cases of anonymized negative patient feedback about junior doctors were analysed using qualitative content analysis. A two-step fine-coding system involving four researchers was employed. Results: Four main themes of communication errors were identified, namely: non-verbal (eye contact, facial expression and paralanguage, verbal (active listening and inappropriate choice of words, and content (poor quantity and quality of information provided; and poor attitudes (lack of respect and empathy. Discussion: Patient-doctor communication is a complex interpersonal interaction that requires an understanding of each party׳s emotional state. We identified important but overlooked communication lapses such as non-verbal paralinguistic elements that should be incorporated into communications curriculum, with an emphasis on dialectical learning. These include integrating these findings into a simulation-based communications module for training doctors at a post-graduate level as well as monitoring and analyzing patient complaints regularly to iteratively update the content of the training module. Beyond these skills training, there is also a need to highlight negative emotions of doctors in future research, as it influences their communication patterns and attitudes towards patients, ultimately shaping how patients perceive them.

Patient value (V) is enhanced when quality (Q) is increased and cost (C) is diminished (V = Q/C). However, calculating value has been inhibited by a lack of risk-adjusted cost data. The aim of this analysis was to measure patient value before and after implementation of quality improvement and cost reduction programs. Multidisciplinary efforts to improve patient value were initiated at a safety-net hospital in 2012. Quality improvement focused on adoption of multiple best practices, and minimizing practice variation was the strategy to control cost. University HealthSystem Consortium (UHC) risk-adjusted quality (patient mortality + safety + satisfaction + effectiveness) and cost (length of stay + direct cost) data were used to calculate patient value over 3 fiscal years. Normalized ranks in the UHC Quality and Accountability Scorecard were used in the value equation. For all hospital patients, quality scores improved from 50.3 to 66.5, with most of the change occurring in decreased mortality. Similar trends were observed for all surgery patients (42.6 to 48.4) and for general surgery patients (30.9 to 64.6). For all hospital patients, cost scores improved from 71.0 to 2.9. Similar changes were noted for all surgical (71.6 to 27.1) and general surgery (85.7 to 23.0) patients. Therefore, value increased more than 30-fold for all patients, 3-fold for all surgical patients, and almost 8-fold for general surgery patients. Multidisciplinary quality and cost efforts resulted in significant improvements in value for all hospitalized patients as well as general surgery patients. Mortality improved the most in general surgery patients, and satisfaction was highest among surgical patients. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc.

To describe the doctors' satisfaction of the doctor-patient relationship and find out the influencing factors of the patients, gathering evidence to improve the doctor-patient relationship. This study was a cross-sectional study, in which doctors and nurses in 10 hospitals of Beijing, Shandong and Chongqing were surveyed with structured questionnaires and in-depth interviews. The mean score of the doctors' satisfaction of the doctor-patient relationship was 59.97, which was much lower than the patients'. The patients' socio-demographic characteristics, social economic status (SES) and behavior characteristics influence the interaction of the doctors and the patients. The doctors' satisfaction of the doctor-patient relationship was influenced by the patients' trust. The doctors' perspective is helpful to define the tension and the cause of the doctor-patient relationship. The patients' characteristics have important influence on the doctor-patient relationship. It's necessary to take action on the patients to improve the doctor-patient relationship.

Autoantibody signature differentiates Wilms tumor patients from neuroblastoma patients.

Directory of Open Access Journals (Sweden)

Jana Schmitt

Full Text Available Several studies report autoantibody signatures in cancer. The majority of these studies analyzed adult tumors and compared the seroreactivity pattern of tumor patients with the pattern in healthy controls. Here, we compared the autoimmune response in patients with neuroblastoma and patients with Wilms tumor representing two different childhood tumors. We were able to differentiate untreated neuroblastoma patients from untreated Wilms tumor patients with an accuracy of 86.8%, a sensitivity of 87.0% and a specificity of 86.7%. The separation of treated neuroblastoma patients from treated Wilms tumor patients' yielded comparable results with an accuracy of 83.8%. We furthermore identified the antigens that contribute most to the differentiation between both tumor types. The analysis of these antigens revealed that neuroblastoma was considerably more immunogenic than Wilms tumor. The reported antigens have not been found to be relevant for comparative analyses between other tumors and controls. In summary, neuroblastoma appears as a highly immunogenic tumor as demonstrated by the extended number of antigens that separate this tumor from Wilms tumor.

The evolving concept of "patient-centeredness" in patient-physician communication research.

Over the past few decades, the concept of "patient-centeredness" has been intensively studied in health communication research on patient-physician interaction. Despite its popularity, this concept has often been criticized for lacking a unified definition and operationalized measurement. This article reviews how health communication research on patient-physician interaction has conceptualized and operationalized patient-centered communication based on four major theoretical perspectives in sociology (i.e., functionalism, conflict theory, utilitarianism, and social constructionism), and discusses the agenda for future research in this field. Each theory addresses different aspects of the patient-physician relationship and communication from different theoretical viewpoints. Patient-centeredness is a multifaceted construct with no single theory that can sufficiently define the whole concept. Different theoretical perspectives of patient-centered communication can be selectively adopted according to the context and nature of problems in the patient-physician relationship that a particular study aims to explore. The present study may provide a useful framework: it offers an overview of the differing models of patient-centered communication and the expected roles and goals in each model; it does so toward identifying a communication model that fits the patient and the context and toward theoretically reconstructing existing measures of patient-centered communication. Furthermore, although patient-centered communication has been defined mainly from the viewpoint of physician's behaviors aimed at achieving patient-centered care, patient competence is also required for patient-centered communication. This needs to be examined in current medical practice. Copyright © 2013 Elsevier Ltd. All rights reserved.

Ensuring a proactive, evidence-based, patient safety approach to patient assessment.

Science.gov (United States)

Considine, Julie; Currey, Judy

2015-01-01

To argue that if all nurses were to adopt the primary survey approach (assessment of airway, breathing, circulation and disability) as the first element of patient assessment, they would be more focused on active detection of clinical deterioration rather than passive collection of patient data. Nurses are the professional group that carry the highest level of responsibility for patient assessment, accurate data collection and interpretation. The timely recognition of, and response to deteriorating patients, is dependent on the measurement and interpretation of pertinent physiological data by nurses. Discursive paper. Traditionally taught and commonly used approaches to patient assessment such as 'vital signs' and 'body systems' are not evidence-based nor framed in patient safety. The primary survey approach as the first element in patient assessment has three major advantages: (1) data are collected according to clinical importance; (2) data are collected using the same framework as most organisation's rapid response system activation criteria; and (3) the primary survey acts as a patient safety checklist, thereby decreasing the risk of failure to recognise, and therefore respond to, deteriorating patients. The vital signs and body systems approaches to patient assessment have significant limitations in identifying clinical deterioration. The primary survey approach provides nurses with a consistent, evidence-based and sequenced approach to patient assessment in every clinical setting. All nurses should use a primary survey approach as the first element of patient assessment in every patient encounter as a patient safety strategy. © 2014 John Wiley & Sons Ltd.

This article looks at how diagnostic radiographers label their patients. An ethnographic study of the workplace culture in one diagnostic imaging department was undertaken using participant observation for four months and semi-structured interviews with ten key informants. One of the key themes; the way in which radiographers label their patients, is explored in this article. It was found from the study that within the department studied the diagnostic radiographers labelled or categorised their patients based on the information that they had. This information is used to form judgements and these judgements were used to assist the radiographers in dealing with the many different people that they encountered in their work. This categorisation and labelling of the patient appears to assist the radiographer in their decision-making processes about the examination to be carried out and the patient they are to image. This is an important aspect of the role of the diagnostic radiographer. - Highlights: • I have studied the culture in one imaging department. • Radiographers label or categorise their patients. • These labels/categories are used to manage the patient. • This is an important aspect of the way in which radiographers work.

Blood transfusion is one of the major areas where serious clinical consequences, even death, related to patient misidentification can occur. In the UK, healthcare professional compliance with pre-transfusion checking procedures which help to prevent misidentification errors is poor. Involving patients at a number of stages in the transfusion pathway could help prevent the occurrence of these incidents. To investigate patients' willingness to be involved and healthcare professionals' willingness to support patient involvement in pre-transfusion checking behaviours. A cross-sectional design was employed assessing willingness to participate in pre-transfusion checking behaviours (patient survey) and willingness to support patient involvement (healthcare professional survey) on a scale of 1-7. One hundred and ten patients who had received a transfusion aged between 18 and 93 (60 male) and 123 healthcare professionals (doctors, nurses and midwives) involved in giving blood transfusions to patients. Mean scores for patients' willingness to participate in safety-relevant transfusion behaviours and healthcare professionals' willingness to support patient involvement ranged from 4.96-6.27 to 4.53-6.66, respectively. Both groups perceived it most acceptable for patients to help prevent errors or omissions relating to their hospital identification wristband. Neither prior experience of receiving a blood transfusion nor professional role of healthcare staff had an effect on attitudes towards patient participation. Overall, both patients and healthcare professionals view patient involvement in transfusion-related behaviours quite favourably and appear in agreement regarding the behaviours patients should adopt an active role in. Further work is needed to determine the effectiveness of this approach to improve transfusion safety. © 2012 The Authors. Transfusion Medicine © 2012 British Blood Transfusion Society.

There is a paucity of data to support evidence-based practices in the provision of patient/family education in the context of a new childhood cancer diagnosis. Since the majority of children with cancer are treated on pediatric oncology clinical trials, lack of effective patient/family education has the potential to negatively affect both patient and clinical trial outcomes. The Children's Oncology Group Nursing Discipline convened an interprofessional expert panel from within and beyond pediatric oncology to review available and emerging evidence and develop expert consensus recommendations regarding harmonization of patient/family education practices for newly diagnosed pediatric oncology patients across institutions. Five broad principles, with associated recommendations, were identified by the panel, including recognition that (1) in pediatric oncology, patient/family education is family-centered; (2) a diagnosis of childhood cancer is overwhelming and the family needs time to process the diagnosis and develop a plan for managing ongoing life demands before they can successfully learn to care for the child; (3) patient/family education should be an interprofessional endeavor with 3 key areas of focus: (a) diagnosis/treatment, (b) psychosocial coping, and (c) care of the child; (4) patient/family education should occur across the continuum of care; and (5) a supportive environment is necessary to optimize learning. Dissemination and implementation of these recommendations will set the stage for future studies that aim to develop evidence to inform best practices, and ultimately to establish the standard of care for effective patient/family education in pediatric oncology.

INTRODUCTION: Patient-controlled hospital admission for individuals with severe mental disorders is a novel approach in mental healthcare. Patients can admit themselves to a hospital unit for a short stay without being assessed by a psychiatrist or contacting the emergency department. Previous...... studies assessing the outcomes of patient-controlled hospital admission found trends towards reduction in the use of coercive measures and length of hospital stay; however, these studies have methodological shortcomings and small sample sizes. Larger studies are needed to estimate the effect of patient-controlled...... hospital admission on the use of coercion and of healthcare services. DESIGN AND METHODS: We aim to recruit at least 315 patients who are offered a contract for patient-controlled hospital admissions in eight different hospitals in Denmark. Patients will be followed-up for at least 1 year to compare...

'What do patients want?' Tailoring medicines information to meet patients' needs.

Science.gov (United States)

Young, Amber; Tordoff, June; Smith, Alesha

2017-11-01

Medicines information leaflets can equip patients to be in control of their own healthcare and support the safe and effective use of medicines. The design and content of leaflets influences patients' willingness to read them, and poor examples can cause patient confusion and anxiety. Researchers examined the literature over the past 8 years to determine the content and design of medicine information leaflets that patients prefer in order to read, understand, and use them effectively. It was found that existing leaflets do not meet patients' needs and appear ineffective. Leaflets lack the information patients seek and may contain non-essential material, affecting patients' perception of, and willingness to read them. Additionally, the acceptable leaflet length varies between patients. Application of good design principles improves readability, comprehension, and ability to locate information. Medicine information leaflets must meet patients' needs and be well designed. Tailoring information leaflets to patient characteristics and requirements would enhance effectiveness. Passive provision of pre-printed leaflets is outdated, unvalued and ineffective. Using automated computer systems for leaflet tailoring with the ability to further adapt patients' information might be the best way forward. Copyright © 2016 Elsevier Inc. All rights reserved.

Patients as educators: interprofessional learning for patient-centred care.

Towle, Angela; Godolphin, William

2013-01-01

Patients with chronic conditions have unique expertise that enhances interprofessional education. Although their active involvement in education is increasing, patients have minimal roles in key educational tasks. A model that brings patients and students together for patient-centred learning, with faculty playing a supportive role, has been described in theory but not yet implemented. To identify issues involved in creating an educational intervention designed and delivered by patients and document outcomes. An advisory group of community members, students and faculty guided development of the intervention (interprofessional workshops). Community educators (CEs) were recruited through community organizations with a healthcare mandate. Workshops were planned by teams of key stakeholders, delivered by CEs, and evaluated by post-workshop student questionnaires. Workshops were delivered by CEs with epilepsy, arthritis, HIV/AIDS and two groups with mental health problems. Roles and responsibilities of planning team members that facilitated control by CEs were identified. Ten workshops attended by 142 students from 15 different disciplines were all highly rated. Workshop objectives defined by CEs and student learning both closely matched dimensions of patient-centredness. Our work demonstrates feasibility and impact of an educational intervention led by patient educators facilitated but not controlled by faculty.

To determine the patient compliance in completing electronically administered patient-reported outcome (PRO) scores following shoulder arthroscopy, and to determine if dedicated research assistants improve patient compliance. Patients undergoing arthroscopic shoulder surgery from January 1, 2014, to December 31, 2014, were prospectively enrolled into an electronic data collection system with retrospective review of compliance data. A total of 143 patients were included in this study; 406 patients were excluded (for any or all of the following reasons, such as incomplete follow-up, inaccessibility to the order sets, and inability to complete the order sets). All patients were assigned an order set of PROs through an electronic reporting system, with order sets to be completed prior to surgery, as well as 6 and 12 months postoperatively. Compliance rates of form completion were documented. Patients who underwent arthroscopic anterior and/or posterior stabilization were excluded. The average age of the patients was 53.1 years, ranging from 20 to 83. Compliance of form completion was highest preoperatively (76%), and then dropped subsequently at 6 months postoperatively (57%) and 12 months postoperatively (45%). Use of research assistants improved compliance by approximately 20% at each time point. No differences were found according to patient gender and age group. Of those completing forms, a majority completed forms at home or elsewhere prior to returning to the office for the clinic visit. Electronic administration of PRO may decrease the amount of time required in the office setting for PRO completion by patients. This may be mutually beneficial to providers and patients. It is unclear if an electronic system improves patient compliance in voluntary completion PRO. Compliance rates at final follow-up remain a concern if data are to be used for establishing quality or outcome metrics. Level IV, case series. Copyright © 2017 Arthroscopy Association of North

A diabetes patient web portal allows patients to access their personal health record and may improve diabetes outcomes; however, patients' adoption is slow. We aimed to get insight into patients' experiences with a web portal to understand how the portal is being used, how patients perceive the content of the portal and to assess whether redesign of the portal might be needed. A survey among 1500 patients with type 1 and type 2 diabetes with a login to a patient portal. 62 primary care practices and one outpatient hospital clinic, using a combined patient portal. We compared patients who requested a login but never used it or once ('early quitters') with patients who used it at least two times ('persistent users'). 632 patients (42.1%) returned the questionnaire. Their mean age was 59.7 years, 63.1% was male and 81.8% had type 2 diabetes. 413 (65.3%) people were persistent users and 34.7% early quitters. In the multivariable analysis, insulin use (OR2.07; 95%CI[1.18-3.62]), experiencing more frequently hyperglycemic episodes (OR1.30;95%CI[1.14-1.49]) and better diabetes knowledge (OR1.02, 95%CI[1.01-1.03]) do increase the odds of being a persistent user. Persistent users perceived the usefulness of the patient portal significantly more favorable. However, they also more decisively declared that the patient portal is not helpful in supporting life style changes. Early quitters felt significantly more items not applicable in their situation compared to persistent users. Both persistent users (69.8%) and early quitters (58.8%) would prefer a reminder function for scheduled visits. About 60% of both groups wanted information about medication and side-effects in their portal. The diabetes patient web portal might be improved significantly by taking into account the patients' experiences and attitudes. We propose creating separate portals for patients on insulin or not.

Reforma tributária: impactos distributivos, sobre o bem-estar e a progressividade

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

Full Text Available Abstract Background Stroke patients' care in hospital tends to be poorly organised, with poor communication and a lack of information being frequent sources of complaint. The purpose of this study was to evaluate whether a patient-held record (PHR would result in greater patient satisfaction and better care planning for stroke patients. Methods A time series control (6 months - intervention (8 months - control (6 months was used among London teaching hospital general medical and geriatric medicine inpatient wards. All stroke patients admitted to the wards during the intervention phase received a PHR and were instructed in its use. Demographic, stroke severity, social factors and outcomes were collected from all stroke patients during all phases of the study. Results Of 252 stroke patients aged 46 to 98 years entered into the study, by six months after admission 118 (46.8% had died. PHR and control group patients were well matched in terms of socio-demographic characteristics and pre-stroke ability. At six months after admission, 119 (97% patients responded to the questionnaire. Just over half (56%, 13 of intervention group patients recalled receiving a PHR. Of those patients, 59% reported reading the PHR, 27% had lost their PHR, and two-thirds said they had difficulties encouraging staff to write in the PHR. Half felt that possession of the PHR was more trouble than it was worth. PHR group patients were more satisfied with the recovery they had made (79% vs. 59%, p=0.04, but felt less able to talk to staff about their problems (61% vs. 82%, p=0.02.

Bacon O

2017-06-01

Full Text Available Background: Inadequate health literacy in adults is a nationwide issue that is associated with worse health outcomes. There is a paucity of literacy regarding rates of inadequate health literacy in psychiatric populations. Objective: The aim of the study was to identify an existing tool that would easily identify patients who had inadequate health literacy, so that a targeted intervention could be performed. Secondarily we attempted to compare rates of inadequate health literacy with providers’ perception of patients’ health literacy. Methods: We assessed health literacy in a psychiatric population by administering the Brief Health Literacy Survey (BHLS. Additionally, all psychiatry residents, psychiatrists, nurse practitioners, pharmacists, and social workers were surveyed to assess their perception of patient health literacy. Differences between patient health literacy and provider expectations of patient health literacy were compared. Results: Inadequate health literacy was identified in 31 out of 61 patients (50.8% using 2 questions from the BHLS. Only 9 (29% of patients who were identified as having inadequate health literacy were identified by both BHLS questions. In contrast, almost 100% of providers identified their patients, in general, as having inadequate health literacy. Conclusions: These results identify a higher rate of health literacy in a psychiatric inpatient population than in the general population. However, providers at this institution likely over-identify health literacy. This highlights the need for a health literacy tool that can easily target patients with inadequate health literacy for an intervention.

Quality of life in patients with dental conditions: comparing patients' and providers' evaluation.

To measure the agreement between patients and their caregivers in evaluating patients' oral quality of life. Cross-sectional study. Data collected in four Swedish dental clinics in 2004. Consecutive patients. Data were completed for 444 patients. Fifteen dentists and 12 dental hygienists agreed to participate. For each patient, the patient him/herself and his/her caregiver completed the 14-item Oral Health Impact Profile (OHIP-14), a specific instrument used to measure quality of life in oral conditions, with higher scores indicating a worse quality of life. Information on personal and clinical characteristics of patients were also collected. Median OHIP-14 scores given by caregivers and patients were calculated and compared in different subgroups of patients. Cohen's kappa was calculated to measure the agreement between the evaluation of patients and caregivers. OHIP-14 scores median values were 3.0 among patients and 9.0 among caregivers. Caregivers always gave a higher score than patients, especially in older patients and patients with lower education. The concordance between patients' and caregivers' evaluation was very low (for different OHIP-14 cutoffs: Cohen's kappa from 0.10 to 0.15). In this study, great discrepancies were observed between patients and caregivers in the evaluation of patients' oral quality of life, with caregivers overestimating the burden of dental conditions on patients. It is important to improve patient-caregiver communication, in order to increase patient satisfaction and provide better care. A good patient-caregiver relationship is essential for the patients' well-being and their adherence to treatment.

General practitioner consultations with patients of non-English speaking background (NESB) account for one in 10 encounters recorded in the BEACH (Bettering the Evaluation and Care of Health) program (NESB is defined as patients who reported that their primary language spoken at home is not English). We present a descriptive comparison of consultations with NESB and English speaking patients recorded between April 2007 and March 2009. Indigenous persons were excluded from the analysis to give a clearer picture of NESB patients of non- Australian origin. Only statistically significant differences with nonoverlapping 95% confidence intervals are reported.

National Committee for Quality Assurance recommends patient-centered medical homes incorporate input from patient populations; however, many health care organizations do not. This qualitative study used two open-ended questions from 148 active duty Army Soldiers and their family members to illicit recommendations for primary care providers and clinic leadership that would improve their health care experiences. Content analysis and descriptive statistics were used to analyze responses. Participant responses were related to four major themes: Access to Care, Interpersonal Interaction, Satisfaction of Care, and Quality of Care. Participants were overall satisfied with their care; however, spending less time waiting for appointments and to see the provider or specialist were the most frequently requested improvements related to Access to Care. For Interpersonal Interaction, 82% of the responses recommended that providers be more attentive listeners, courteous, patient, caring, and respectful. Decreasing wait times and improving interpersonal skills would improve health care experiences and patient satisfaction. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

Patient satisfaction with emergency care is associated with timeliness of care, empathy, technical competence, and information delivery. Previous studies have demonstrated inconsistent findings regarding the association between pain management and patient satisfaction. This study was undertaken to determine the association between pain management and patient satisfaction among Emergency Department (ED) patients presenting with acute painful conditions. In this survey study, a standardized interview was conducted at the Emergency Department at the University of Toledo Medical Center in May-July 2011. Participants were asked to answer 18 questions pertaining to patient satisfaction. Additional data collected included demographic information, pain scores, and clinical management. Among 328 eligible participants, 289 (88%) participated. The mean triage pain score on the verbal numeric rating scale was 8.2 and the mean discharge score was 6.0. The majority of patients (52%) experienced a reduction in pain of 2 or more points. Participants received one pain medication dose (44%), two medication doses (14%), three medication doses (5%), or four medication doses (2%). Reduction in pain scores of 2 or more points was associated with a higher number of medications administered. Reduction in pain scores was associated with higher satisfaction as scored on questions of patient perceptions of adequate assessment and response to pain, and treatment of pain. There was a significant association between patient satisfaction and a reduction in pain of 2 or more points and number of medications administered. Effective pain management is associated with improved patient satisfaction among ED patients with painful conditions. Copyright © 2014 Elsevier Inc. All rights reserved.

Full Text Available The present study aims to assess how patient satisfaction with medical provider-patient communication can affect oral health, diabetes, and psychobehavioural measures among type 2 diabetes (T2DM patients. It is part of a prospective intervention study among randomly selected T2DM patients, in Turkey. The data analyzed were Community Periodontal Need Index (CPI, HbA1c, patient satisfaction with communication, and psychobehavioural variables. Data was collected initially and at the end of the intervention. The participants were allocated to either health coaching (HC or health education (HE. At baseline, there were no statistical differences between the HC and the HE groups on any of the measures (P>0.05. Patients in both the HC and the HE groups had low satisfaction with communication. At postintervention, the increase in patient satisfaction with communication in the HC group was significantly higher than that in the HE group (P=0.001. Principal component analysis revealed that patient satisfaction with communication shared the same cluster with clinical measures (CPI and HbA1c and quality of life in the HC group. In conclusion, the present study showed, to our knowledge for the first time, that overall patient satisfaction with medical care provider-patient communication, empowered by HC approach, was interrelated with well-being of T2DM patients, in terms of psychobehavioural and clinical measures.

The goal of patient satisfaction addresses both a care-oriented approach to the patient and also deploys market perceptions of patients as homogeneous target groups...... for which information can be standardized. In the latter approach (market orientation), the patient is also a resource for organizational development. Overall, the strategy presents an information-pursuing patient figure that makes it possible to streamline the organization's care orientation on market......Over the past decade, patient communication has become a strategic priority in Danish public hospitals: communication is a focal point of policies, plans and daily work practices.

2015-11-01

Full Text Available With the emerging trend of patient family–centered care in health care, it is essential that physicians be exposed to patient and family perspectives of care during medical education and training. Grand Rounds provides an ideal format for physicians to learn about patient family–centered care. At Brigham and Women’s Hospital, we sought to bring the voice of the patient to Patient Family–Centered Grand Rounds in order to expose clinicians to rich narratives describing the medical care received by patients/families and to ultimately change physician practice to reflect patient family–centered principles. We conducted a clinician survey and found promising results indicating that patient/family narratives can be effective at educating physicians about patient family–centered care.

Full Text Available Background and ObjectivesDiabetic patients play the main role in the management of their disease. Adequate knowledge of this disease state and self directed patient care will improve the health of these patients. Some studies have indicated a high prevalence of diabetes complication are due to the lack of knowledge of self directed patient care and practice in diabetic patient group. The objective of this study is to measure the knowledge level of self directed patient care and practice in order to evaluate their effects on improvement of diabetic patients' health in the city of Qom, Iran.MethodsIn this cross sectional study 1004 patients with diabetes participated (During year 2006. Data were collected from patients of General Hospital metabolism and endocrine research center.An interviewing method was used to asses the demographics data, history of disease, and knowledge of self directed patient care in these patients. Data were analyzed using a descriptive statistic, chi-square, and Pearson correlation coefficient, and SPSS software.ResultsOut of 1004 observed case, 154 patients were with Diabetes type I and 850 patients with Diabetes type II. The knowledge of self directed patient care and practice level of with both types of diabetes were determined to be mostly at an intermediate level. In type I diabetic patients there was a significant relation between knowledge level of self directed patient care and gender of the patients (P=0.01. Also, there was a significant correlation between practice and age (P=0.03(, and economical status (P=0.06 of the patients. In type II diabetic patients there was a significant relation between knowledge level of self directed patient care and educational level (P=0.00(, and economical status (P=0.01 of the patients.

Patient-Ventilator Dyssynchrony

Full Text Available In mechanically ventilated patients, assisted mechanical ventilation (MV is employed early, following the acute phase of critical illness, in order to eliminate the detrimental effects of controlled MV, most notably the development of ventilator-induced diaphragmatic dysfunction. Nevertheless, the benefits of assisted MV are often counteracted by the development of patient-ventilator dyssynchrony. Patient-ventilator dyssynchrony occurs when either the initiation and/or termination of mechanical breath is not in time agreement with the initiation and termination of neural inspiration, respectively, or if the magnitude of mechanical assist does not respond to the patient’s respiratory demand. As patient-ventilator dyssynchrony has been associated with several adverse effects and can adversely influence patient outcome, every effort should be made to recognize and correct this occurrence at bedside. To detect patient-ventilator dyssynchronies, the physician should assess patient comfort and carefully inspect the pressure- and flow-time waveforms, available on the ventilator screen of all modern ventilators. Modern ventilators offer several modifiable settings to improve patient-ventilator interaction. New proportional modes of ventilation are also very helpful in improving patient-ventilator interaction.

To examine changes in patient experience across key domains of the patient-centered medical home (PCMH) following practice transformation with Lean quality improvement methodology inclusive of payment reform. Pre-intervention/post-intervention analysis of intervention with a comparison group, a quasi-experimental design. We surveyed patients following office visits at the intervention (n = 2502) and control (n = 1622) practices during the 15-month period before and 14-month period after PCMH Lean transformation (April-October 2009). We measured and compared pre-intervention and post-intervention levels of patient satisfaction and other indicators of patient-centered care. Propensity weights adjusted for potential case-mix differences in intervention and control groups; propensity-adjusted proportions accounted for physician-level clustering. More intervention patients were very satisfied with their care after the PCMH Lean intervention (68%) compared with pre-intervention (62%). Among control patients, there was no corresponding increase in satisfaction (63% very satisfied pre-intervention vs 64% very satisfied post-intervention). This comparison resulted in a statistical trend (P = .10) toward greater overall satisfaction attributable to the intervention. Post-intervention, patients in the intervention practice consistently rated indicators of patient-centered care higher than patients in the control practice, particularly in the personal physician and communication domain. In this domain, intervention patients reported superior provider explanations, time spent, provider concern, and follow-up instructions compared with control participants, whereas control group ratings fell in the post-intervention period (P for difference Lean enhancement with payment reform, patient experience was sustained or improved across key PCMH domains.

Good doctor-patient communication may lead to better compliance, higher patient satisfaction, and finally, better health. Although the social variance in how physicians and patients communicate is clearly demonstrated, little is known about what patients with different educational attainments actually prefer in doctor-patient communication. In this study we describe patients' perspective in doctor-patient communication according to their educational level, and to what extent these perspectives lean towards the expert opinion on doctor-patient communication. In a multi-center study (Belgium, The Netherlands, UK and Italy), focus group discussions were organised using videotaped medical consultations. A mixed methods approach was used to analyse the data. Firstly, a difference in perspective in communication style was found between the lower educated participants versus the middle and higher educated participants. Secondly, lower educated participants referred positively most to aspects related to the affective/emotional area of the medical consultation, followed by the task-oriented/problem-focused area. Middle and higher educated participants positively referred most to the task-oriented/problem-focused area. The competency of the physician was an important category of communication for all participants, independent of social background. The results indicate that the preferences of lower educated participants lean more towards the expert opinion in doctor-patient communication than the middle and higher educated participants. Patients' educational level seems to influence their perspective on communication style and should be taken into account by physicians. Further quantitative research is needed to confirm these results.

Including target populations in the design and implementation of research trials has been one response to the growing health disparities endemic to our health care system, as well as an aid to study generalizability. One type of community-based participatory research is "Patient Centered-Research", in which patient perspectives on the germane research questions and methodologies are incorporated into the study. The Patient-Centered Outcomes Research Institute (PCORI) has mandated that meaningful patient and stakeholder engagement be incorporated into all applications. As of March 2015, PCORI funded seven clinically-focused studies of patients with kidney disease. The goal of this paper is to synthesize the experiences of these studies to gain an understanding of how meaningful patient and stakeholder engagement can occur in clinical research of kidney diseases, and what the key barriers are to its implementation. Our collective experience suggests that successful implementation of a patient- and stakeholder-engaged research paradigm involves: (1) defining the roles and process for the incorporation of input; (2) identifying the particular patients and other stakeholders; (3) engaging patients and other stakeholders so they appreciate the value of their own participation and have personal investment in the research process; and (4) overcoming barriers and challenges that arise and threaten the productivity of the collaboration. It is our hope that the experiences of these studies will further interest and capacity for incorporating patient and stakeholder perspectives in research of kidney diseases.

However, the ideal of involving patients in quality improvement is described in very general terms and with only few specific expectations of how it is to be carried out...... in practice, as I show in the thesis. In the patient involvement literature, the difficulties of getting patient involvement in quality improvement to have in an impact on the planning and development of healthcare services is, for example, ascribed to conceptual vagueness of patient involvement, differences...... in perspectives, values and understandings between patients and healthcare professionals, or the lack of managerial attention and prioritization....

An increasing interest in alternative medicine can be explained by the inefficiency of conventional treatment, dissatisfaction with treating patients like objects, and the will to use all available treatment methods. Objectives . The authors assessed how often patients use CAM methods, and which of them are most popular. Material and methods . The study was conducted in Military Hospital no. 109 and the Independent Public Clinical Hospital no. 1 in Szczecin among 100 chemotherapy patients. This survey-based study was performed using an original questionnaire. Results. Most respondents (68% did not use alternative methods to fight the disease. The most popular treatment methods were: herbal medicine (50%, alternative medicine preparations (38% and diet (25%, and the least common: hypnosis (3% and aromatherapy (3%. Analyzed sociodemographic factors had no effects on a choice of a CAM method. Patients obtained information about CAM methods mainly from the Internet (40%, medical staff (37% and literature (31%. Conclusions . 1. Using CAM by patients receiving chemotherapy for neoplasms is quite a common phenomenon. 2. CAM were more often chosen by women. Neither the duration of the disease nor sociodemographic data had effects on making the decision to use CAM methods. 3. The most popular CAM were: herbal medicine, alternative medicine preparations, and diet. 4. Cancer patients should receive special support from nurses and doctors as well as other members of the therapeutic team. Oncology patients should never be left on their own so that they were forced to seek help and support in therapies unconfirmed by scientific investigation.

To investigate patient perceptions of patient-centered communication (PCC) in doctor-patient consultations and explore barriers to PCC implementation in China. This study was conducted in public teaching hospital in Guiyang, Guizhou, China. In Phase 1, patient attitudes to PCC were quantitatively assessed in 317 outpatients using modified Patient-Practitioner Orientation Scale (PPOS). In Phase 2, we conducted in-depth interviews with 20 outpatients to explore their views on PCC and expose potential barriers to PCC implementation. Participants communicated "patient-centered" preferences, particularly with regard to their doctors' empathy, communication skills, time and information sharing. Patients were more concerned about doctors exhibiting caring perspective than power sharing. Younger and highly educated patients were more likely to prefer PCC and highly educated patients paid more attention to power sharing. Several factors including inadequate time for PCC resulting from doctors' high patient-load, doctor-patient communication difficulties and excessive treatment due to inappropriate medical payment system affected PCC implementation in China. Patients expressed moderate enthusiasm for PCC in China. They expressed strong preferences concerning physician respect for patient perspective, but less concern for power sharing. Government should improve health care system by implementing PCC in daily healthcare practice to improve patient awareness and preferences. Copyright © 2016. Published by Elsevier Ireland Ltd.

Display methods of electronic patient record screens: patient privacy concerns.

Niimi, Yukari; Ota, Katsumasa

2013-01-01

To provide adequate care, medical professionals have to collect not only medical information but also information that may be related to private aspects of the patient's life. With patients' increasing awareness of information privacy, healthcare providers have to pay attention to the patients' right of privacy. This study aimed to clarify the requirements of the display method of electronic patient record (EPR) screens in consideration of both patients' information privacy concerns and health professionals' information needs. For this purpose, semi-structured group interviews were conducted of 78 medical professionals. They pointed out that partial concealment of information to meet patients' requests for privacy could result in challenges in (1) safety in healthcare, (2) information sharing, (3) collaboration, (4) hospital management, and (5) communication. They believed that EPRs should (1) meet the requirements of the therapeutic process, (2) have restricted access, (3) provide convenient access to necessary information, and (4) facilitate interprofessional collaboration. This study provides direction for the development of display methods that balance the sharing of vital information and protection of patient privacy.

The Act of 6 November 2008 on Patients' Rights and the Commissioner for Patients' Rights collect and safeguard patients' basic rights as well as provide, for the first time in Poland, an original concept for patients' collective rights. In addition, the new Act stipulates the specific mechanism for protecting patients' rights by the newly established body called the Commissioner for Patients' Rights. Polish reform of medical law will undoubtedly contribute to the expected ratification of the Convention on Human Rights and Biomedicine. However, the nature of codified rights is relatively abstract, and the Act cannot be read without reference to legislation related to physicians and health care institutions.
