A method of retrieving thermophysical depth profiles of continuously inhomogeneous materials is presented both theoretically and experimentally using the three-dimensional (3-D) photothermal radiometry. A 3-D theoretical model suitable for characterizing solids with arbitrary continuously varying thermophysical property depth profiles and finite (collimated or focused) laser beam spotsize is developed. A numerical fitting algorithm to retrieve the thermophysical profile was demonstrated with three case hardened steel samples. The reconstructed thermal conductivity depth profiles were found to be well anti-correlated with microhardness profiles obtained with the conventional indenter method.

Recently, the input-profile-based testing for safety critical software has been proposed for determining the number of test cases and quantifying the failure probability of the software. Input-profile of a reactor protection system (RPS) software is the input which causes activation of the system for emergency shutdown of a reactor. This paper presents a method to determine the input-profile of a RPS software which considers concurrent events/transients. A deviation of a process parameter value begins through an event and increases owing to the concurrent multi-events depending on the correlation of process parameters and severity of incidents. A case of reactor trip caused by feedwater loss and main steam line break is simulated and analyzed to determine the RPS software input-profile and estimate the number of test cases. The different sizes of the main steam line breaks (e.g., small, medium, large break) with total loss of feedwater supply are considered in constructing the input-profile. The uncertainties of the simulation related to the input-profile-based software testing are also included. Our study is expected to provide an option to determine test cases and quantification of RPS software failure probability. (author)

2005-08-01

Full Text Available Abstract Background Cancer serum protein profiling by mass spectrometry has uncovered mass profiles that are potentially diagnostic for several common types of cancer. However, direct mass spectrometric profiling has a limited dynamic range and difficulties in providing the identification of the distinctive proteins. We hypothesized that distinctive profiles may result from the differential expression of relatively abundant serum proteins associated with the host response. Methods Eighty-four antibodies, targeting a wide range of serum proteins, were spotted onto nitrocellulose-coated microscope slides. The abundances of the corresponding proteins were measured in 80 serum samples, from 24 newly diagnosed subjects with lung cancer, 24 healthy controls, and 32 subjects with chronic obstructive pulmonary disease (COPD. Two-color rolling-circle amplification was used to measure protein abundance. Results Seven of the 84 antibodies gave a significant difference (p Conclusion Our results suggest that a distinctive serum protein profile involving abundant proteins may be observed in lung cancer patients relative to healthy subjects or patients with chronic disease and may have utility as part of strategies for detecting lung cancer.

Langerhans'cell histiocytosis (Histiocytosis X) is a rare disease of unknown cause characterized by oligoclonal proliferation of Langerhans cells. It occurs mostly in children and young adults and involves one or more body systems such as bone, hypothalamus, posterior pituitary gland, lymph nodes, liver or various soft tissues. The diagnosis is always made by a histological approach. We report a case of Langerhans'cell histiocytosis in a young patient with clinical signs of diabetes insipidus and hepatic involvement in whom the immunohistochemical analysis of the liver tissue led to the definitive diagnosis.

This exploratory study examines the delivery of child protection services by county child protection agencies involving cases with a family member with a disability. Telephone surveys were conducted with the directors or their designees of 89% of the child protection agencies in a Midwestern state. Respondents were asked about the policies and/or procedures for approaching cases involving a person with a disability and the barriers and strengths agencies have in serving people with disabilities. Only 6.7% of respondents reported their agency had a written policy related to serving persons with a disability. There were 18 different approaches to serving clients with a disability within child protection, with the most common being informally teaming for information, dual case assignment, and teaming with an outside consultant. Five counties had specialty workers who were experts in both child protection and disability. Barriers reported varied between rural and non-rural counties, with the most important barriers being lack of resources, lack of knowledge regarding disabilities, systems conflicts, and rural issues, such as lack of providers and lack of transportation. Strengths included accessing and coordinating services, individualizing services, good collaboration and creativity. While few county agencies had any written policies, both formal and informal collaboration is happening at the individual level. The lack of standardization in providing services indicates a need for more attention to issues regarding disability within child protection, including more training for workers, the development of models of collaborative case management and the removal of systemic barriers.

2015-07-01

Full Text Available The aim of this study is to examine the involvement of families in child protection cases in Iceland, as well as to shed light on the attitudes of child protection workers on the importance of including families while working on child protection cases. The study is part of an international comparative analysis called: Social Work with Families: Social Workers’ Constructions of Family in Professional Practice. This article only addresses the Icelandic segment of the research. In the study, qualitative methods were used and three focus groups were conducted, in which the same three-step vignette about a child protection case was presented. The findings highlighted how difficult child protection workers found it to define the family. The main element is that family are those individuals closest to the child and connected to them through emotional ties, as Icelandic child protection workers seem to strive to involve family in child protection cases. However, there are signs which show that when working with more complicated cases the definition of a family becomes narrower, and involvement is restricted mostly to parents and grandparents. The findings also show that attitudes toward fathers differ from those toward mothers. The mother is expected to support and create security for the child, while the father is judged mostly on his violent behaviour and is not automatically regarded as providing support or actively taking responsibility for his child.

Ahmadieh, Azadeh; Farnad, Fariborz; Sedghizadeh, Parish P

2014-11-05

Gaucher disease is an autosomal recessive systemic condition, and the most common of the lysosomal storage disorders. It is characterized by lipid accumulation in certain cells and organs, particularly macrophages, which appear on light microscopy as 'Gaucher cells' or vacuolated lipid-laden reticuloendothelial cells. Long bone involvement is common in Gaucher disease, whereas craniofacial bone involvement is extremely rare. Reports confirming the diagnoses of Gaucher disease involving craniofacial bones by histopathologic evidence are even rarer. A 46-year-old Caucasian Ashkenazi Jewish woman with Gaucher disease presented with jawbone pain and lytic radiographic lesions of her mandible. Surgical biopsy of a mandibular lesion revealed Gaucher cells infiltrating the mandible, which correlated with radiographic and clinical findings, supporting a diagnosis of Gaucher disease with jawbone involvement. Lysosomal storage diseases can have head and neck manifestations, and bone involvement in Gaucher disease is common. Therefore, careful consideration of signs and symptoms and medical history, with a thorough review of systems, is important when evaluating patients with lysosomal storage disorders to rule out head and neck involvement of disease. Biopsy may be warranted in some cases for more definitive diagnosis of painful jawbone lesions and to rule out other odontogenic and non-odontogenic conditions in the differential diagnosis.

The attrition of rape cases from the criminal justice system (CJS) remains high and there is a paucity of research in relation to marginalized groups. Sex workers (SWs) are vulnerable to sexual violence due to the nature of their work. They are also unlikely to report such violence to police for a range of reasons. Two stages of research sought to describe the victim, perpetrator, and offense characteristics of SW rape and to examine the attrition of these cases. All rapes and attempted rapes (N = 1,146) reported to police in a large city in the South West of England over a 21-year period were examined; 67 cases involved SWs. Data were extracted from police files in line with the variables of interest. Secondary analysis of the total number of SW rapes (n = 67) resulted in a profile of these cases. A matched pairs study revealed significant differences in victim, perpetrator, and assault characteristics between SW (n = 62) and non-sex-worker (NSW) samples (n = 62). Although no significant difference was found in terms of attrition from the CJS, SW cases were observed to secure more convictions for rape than NSW cases. The implications of the findings for practice and future research are discussed. © The Author(s) 2015.

Polyarteritis nodosa (PAN) is a systemic necrotizing vasculitis that involves medium- and small-sized arteries. PAN may affect any organ, and the presenting symptom of PAN varies depending on the organs affected. However, PAN generally spares the lung; thus, a report of PAN involving the bronchial artery is extremely rare, and hemoptysis has not been reported as the sole presenting symptom. Here, we report the case of a 39-year-old woman with hemoptysis who was diagnosed with PAN involving only the bronchial artery by angiography without involvement of the visceral arteries. Details of this case and a literature review are presented.

Carfentanil is a fentanyl analog frequently used in large animal veterinary medicine. Recently, carfentanil has been discovered in postmortem and antemortem cases throughout the United States in the heroin supply either alone or mixed with heroin and/or other fentanyl analogs. The potency of carfentanil is ~10,000 times greater than morphine and 100 times greater than fentanyl. In two recent cases, carfentanil was identified and ruled to be the cause of death, either alone or in combination with other drugs. Case 1 involved a known heroin user. He was discovered slumped over in a running van blocking the bays of a carwash. Two syringes, a spoon with cotton and residue and a yellow baggie of powder were found in the van. Case 2 involved a man living in a tent in a park with his mother. He was last heard from by a sister via phone who stated he sounded very intoxicated and by his mother who noted him to be "itching all over" and upset over his girlfriend. When the mother returned from work, she discovered him unresponsive with a small baggie of brown powder next to him. Routine drug and volatile screening tests were performed on heart blood using headspace gas chromatography, immunoassay and gas chromatography mass spectrometry methods. Results from initial testing on both cases did not have any significant toxicological findings. However, due to the history, scene photos, toxicological findings in blood and urine and analysis of the drug paraphernalia on one of the cases which identified carfentanil and furanyl fentanyl, fentanyl analogues were suspected. Heart blood was sent to a reference laboratory for carfentanil and furanyl fentanyl analysis. Case 1 had a carfentanil concentration of 1.3 ng/mL and a furanyl fentanyl concentration of 0.34 ng/mL. Case 2 had a carfentanil concentration of 0.12 ng/mL. © The Author 2017. Published by Oxford University Press. All rights reserved. For Permissions, please email: journals.permissions@oup.com.

This case report and literature review reports on a rare case of facial nerve hemangioma (FNH) involving the vertical facial nerve (FN) segment, and discusses the clinical presentation, imaging, pathogenesis, and management of these rare lesions. A 53-year-old male presented with a 10-year history of right hemifacial twitching and progressive facial paresis (House-Brackmann grading score V/VI). The computed tomography and magnetic resonance imaging studies confirmed an expansile lesion along the vertical FN segment. Excision and histopathologic examination demonstrated FNH. FNHs involving the vertical FN segment are extremely rare. Despite being rare lesions, we believe that familiarity with the presentation and management of FNHs are imperative. Laryngoscope, 2012.

As a specialized organ, the insect ovary performs valuable functions by ensuring fecundity and population survival. Oogenesis is the complex physiological process resulting in the production of mature eggs, which are involved in epigenetic programming, germ cell behavior, cell cycle regulation, etc. Identification of the genes involved in ovary development and oogenesis is critical to better understand the reproductive biology and screening for the potential molecular targets in Plutella xylostella, a worldwide destructive pest of economically major crops. Based on transcriptome sequencing, a total of 7.88Gb clean nucleotides was obtained, with 19,934 genes and 1861 new transcripts being identified. Expression profiling indicated that 61.7% of the genes were expressed (FPKM≥1) in the P. xylostella ovary. GO annotation showed that the pathways of multicellular organism reproduction and multicellular organism reproduction process, as well as gamete generation and chorion were significantly enriched. Processes that were most likely relevant to reproduction included the spliceosome, ubiquitin mediated proteolysis, endocytosis, PI3K-Akt signaling pathway, insulin signaling pathway, cAMP signaling pathway, and focal adhesion were identified in the top 20 'highly represented' KEGG pathways. Functional genes involved in oogenesis were further analyzed and validated by qRT-PCR to show their potential predominant roles in P. xylostella reproduction. Our newly developed P. xylostella ovary transcriptome provides an overview of the gene expression profiling in this specialized tissue and the functional gene network closely related to the ovary development and oogenesis. This is the first genome-wide transcriptome dataset of P. xylostella ovary that includes a subset of functionally activated genes. This global approach will be the basis for further studies on molecular mechanisms of P. xylostella reproduction aimed at screening potential molecular targets for integrated pest

Sonographic biophysical profile in detection of foetal hypoxia in 100 cases of suspected high risk pregnancy

International Nuclear Information System (INIS)

Ullah, N.; Khan, A.R.; Usman, M.

2010-01-01

Background: The foetus has become increasingly accessible and visible as a patient over the last two decades. Ultrasound imaging has broadened the scope of foetal assessment. Dynamic real time B-Mode ultrasound is used to monitor cluster of biophysical variables, both dynamic and static collectively termed as biophysical profile. The purpose of this study was to determine the effect of sonographic biophysical profile score on perinatal outcome in terms of mortality and morbidity. Methods: This descriptive study was carried on 100 randomly select ed high risk pregnant patients in Radiology Department PGMI, Government Lady Reading Hospital, Peshawar from December 2007 to June 2008. Manning biophysical profile including non-stress was employed for foetal screening, using Toshiba ultrasound machine model Nemio SSA-550A and 7.5 MHZ probe. Results: Out of 100 cases 79 (79%) had a normal biophysical profile in the last scan of 10/10 and had a normal perinatal outcome with 5 minutes Apgar score >7/10. In 13 (13%) cases Apgar score at 5 minute was < 7/10 and babies were shifted to nursery. There were 2 (2%) false positive cases that showed abnormal biophysical profile scores of 6/10 but babies were born with an Apgar score of 8/10 at 5 minutes. There were 2 (2%) neonatal deaths in this study group. The sensitivity of biophysical profile was 79.1%, specificity 92.9%. Predictive value for a positive test was 98.55%; predictive value for a negative test was 41.93%. Conclusion: Biophysical profile is highly accurate and reliable test of diagnosing foetal hypoxia.

Laing, R M; Bryant, V

1991-08-28

The effectiveness of legislative intervention in the New Zealand market for children's nightclothes as an injury prevention strategy has been reassessed by examining those hospital admissions for the period 1980-8 (with emphasis on the 1985-8 period) in which clothing and/or nightclothes were involved. The profiles of the production of children's nightclothes (1977-86) and domestic heating (1984-8) were also examined. Ninety-five cases of burn injury discharges were identified (1985-8), and of those cases involving clothing 42% involved nightwear (49% 1981-4). Some of the 27% unspecified cases may have also involved nightwear (23%, 1981-4). A very strong linear downward trend for nightwear incidents was noted (chi 2 slope = 31.06, p less than 0.001). Forty-eight percent of cases involved children aged 1-6 years, and 68% involved pajamas. Stoves were the main specified ignition agent for nightclothes (36%). Open fires as a form of household heating decreased from 49% to 34% of households (1984-8). Estimated production of nightdresses in New Zealand also decreased (460,000 to 80,000 units, 1973-86). The pronounced decrease in injuries attributable to ignition of children's nightclothes is likely to be the result of mandatory controls on children's nightclothes, increased use of pyjamas, and a steady decrease in use of open fires and portable electric heaters. The typical injury event portrayed to the public of a girl in front of a heater or open fire needs to be corrected.

Flannery, Dustin D; Stephens, Clare L; Thompson, Amy D

2016-01-01

High-profile media cases of sexual abuse may encourage disclosures of abuse from victims of unrelated assaults and also influence parental concerns, leading to increased emergency department visits. In the region of the study authors' institution, there are two recent high-profile sexual abuse cases with media coverage: Earl Bradley, a Delaware pediatrician, and Jerry Sandusky, a Pennsylvania college football coach. This is a retrospective cohort study of children evaluated for sexual abuse at a pediatric emergency department. Patients were classified as either presenting during a media period or non-media period. The media periods were one-month periods immediately following breaking news reports, when the cases were highly publicized in the media. The non-media periods were the 12-month periods directly preceding the first reports. The median number of emergency department visits per month during a non-media period was 9 visits (interquartile range 6-10). There were 11 visits in the month following the Sandusky case and 13 visits following the Bradley case. There was no statistical difference in number of emergency department visits for sexual abuse between the periods (p = .09). These finding have implications regarding use of resources in pediatric EDs after high-profile sexual abuse cases.

Damodaran, Shivashankar; Gengan, Devakannan; Walling, Sashi T

2017-07-01

Aggressive angiomyxoma is a rare benign mesenchymal stromal tumour, characterized by locally infiltrative nature and a tendency for recurrence. Only a few cases of penile involvement have been reported in the literature so far. We report a case of aggressive penile angiomyxoma in a sixty-two-year-old obese, diabetic male patient. He presented with obstructive lower urinary tract symptoms (LUTS) and diffuse enlargement of the penis and scrotum. He was managed with excision, reduction scrotoplasty, internal urethrotomy, followed by Leuprolide therapy for prevention of recurrence. He is on follow up for 20 months without recurrence and obstructive symptoms.

Doo, Kyung Won; Yong, Hwan Seok; Kang, Eun-Young

2013-12-01

We report a case of Churg-Strauss syndrome (CSS) associated with coronary artery involvement, as demonstrated on coronary CT angiography (CCTA), without specific cardiac symptoms. A 69-year-old male had an 8-year history of bronchial asthma and chronic sinusitis with hypereosinophilia (35 %), polyneuropathy, and a positive antineutrophil cytoplasmic antibody titer, so he was diagnosed with CSS. The patient had no specific cardiac symptoms, but CCTA showed vasculitis and a saccular aneurysm involving the proximal coronary arteries. The 3-year follow-up CCTA demonstrated an increase in the extent of soft-tissue wall thickening and infiltration involving the coronary arteries. Although vasculitis of the major coronary arteries is not a prominent feature of CSS, our case suggests that the coronary arteries may also be targeted in this syndrome.

Flipse, Steven M; Puylaert, Steven

2018-02-01

Following societal and policy pressures for responsible innovation, innovators are more and more expected to consider the broader socio-ethical context of their work, and more importantly, to integrate such considerations into their daily practices. This may require the involvement of 'outsiders' in innovation trajectories, including e.g. societal and governmental actors. However, methods on how to functionally organize such integration in light of responsible innovation have only recently started to emerge. We present an approach to do just that, in which we first develop value profiles of the involved actors, and second, design a workshop setting that allows innovators to develop design requirements in collaboration with representatives of parties that are not usually involved in such innovation design practices. Using a case study in automated vehicle development, we positively demonstrate the possibility and utility of our approach. We stress that in this study we wish to demonstrate the functionality of our developed method, and did not search for scientifically valid outcomes regarding this technical field.

A retrospective study of all patients presenting with abdominal malignancies since November 1982 was undertaken in order to assess the CT features of peritoneal and mesenteric involvement in childhood. Thirteen cases, including 4 cases of malignant lymphomas, 1 case of Hodgkin's disease, 5 cases of adrenal tumors and 3 cases of ovarian tumors, were selected. Providing a good technique, CT appears as the best imaging modality of the mesentery. CT is also reliable in showing peritoneal implants, even without ascites. A high quality vascular opacification is needed in order to recognize the involvement of the lesser omentum (6/13 cases in our series). Precise knowledge of the intra-abdominal extension of the primary neoplasm has a definite impact upon the surgical indications and therefore upon the prognosis [fr

Injuries now rank among the leading causes of morbidity and mortality the world over. Injuries are steadily increasing in developing countries like India. Systematic and scientific efforts in injury prevention and control are yet to begin in India. Data on injuries are very essential to plan preventive and control measures. The objective of this study is to know the profile of the injury cases admitted to M S Ramaiah hospital, Bangalore, India, using a cross-sectional study design for six months, i.e. from Oct 2008 to April 2009. The mean age of the study population was 35.3 years (SD = 15.38), 69.1% were injured in road traffic accidents (RTA), 28.7% due to falls and 2.2% due to burns. Nearly 14.4% were under the influence of alcohol. Nearly 73.6% of RTA cases were two-wheeler users, 48.5% had not followed sign boards and 56.5% had not obeyed the one-way rules, 63.5% of the two-wheeler users did not use helmets. Also, 38% of two wheelers had two pillion riders, whereas 57% of four-wheeler users had not used a seat belt. Among falls, 58% occurred at home, 49% occurred due to slippery surface. Road traffic accidents were the most common cause for injuries, in which two wheelers were most commonly involved. Strict enforcement of traffic rules and education on road safety are very essential to prevent injuries.

Cancer serum protein profiling by mass spectrometry has uncovered mass profiles that are potentially diagnostic for several common types of cancer. However, direct mass spectrometric profiling has a limited dynamic range and difficulties in providing the identification of the distinctive proteins. We hypothesized that distinctive profiles may result from the differential expression of relatively abundant serum proteins associated with the host response. Eighty-four antibodies, targeting a wide range of serum proteins, were spotted onto nitrocellulose-coated microscope slides. The abundances of the corresponding proteins were measured in 80 serum samples, from 24 newly diagnosed subjects with lung cancer, 24 healthy controls, and 32 subjects with chronic obstructive pulmonary disease (COPD). Two-color rolling-circle amplification was used to measure protein abundance. Seven of the 84 antibodies gave a significant difference (p < 0.01) for the lung cancer patients as compared to healthy controls, as well as compared to COPD patients. Proteins that exhibited higher abundances in the lung cancer samples relative to the control samples included C-reactive protein (CRP; a 13.3 fold increase), serum amyloid A (SAA; a 2.0 fold increase), mucin 1 and α-1-antitrypsin (1.4 fold increases). The increased expression levels of CRP and SAA were validated by Western blot analysis. Leave-one-out cross-validation was used to construct Diagonal Linear Discriminant Analysis (DLDA) classifiers. At a cutoff where all 56 of the non-tumor samples were correctly classified, 15/24 lung tumor patient sera were correctly classified. Our results suggest that a distinctive serum protein profile involving abundant proteins may be observed in lung cancer patients relative to healthy subjects or patients with chronic disease and may have utility as part of strategies for detecting lung cancer

The aim was to explore the process of involving mental healthcare service users in a mental health promotion research project as research advisors and to articulate features of the collaboration which encouraged and empowered the advisors to make significant contributions to the research process and outcome. There is an increasing interest in evaluating aspects of service user involvement in nursing research. Few descriptions exist of features that enable meaningful service user involvement. We draw on experiences from conducting research which used the methodology interpretative phenomenological analysis to explore how persons with mental disorders perceived mental health. Aside from the participants in the project, five research advisors with service user experience were involved in the entire research process. We applied a case study design to explore the ongoing processes of service user involvement. Documents and texts produced while conducting the project (2012-2016), as well as transcripts from multistage focus group discussions with the research advisors, were analysed. The level of involvement was dynamic and varied throughout the different stages of the research process. Six features: leadership, meeting structure, role clarification, being members of a team, a focus on possibilities and being seen and treated as holistic individuals, were guiding principles for a salutogenic service user involvement. These features strengthened the advisors' perception of themselves as valuable and competent contributors. Significant contributions from research advisors were promoted by facilitating the process of involvement. A supporting structure and atmosphere were consistent with a salutogenic service user involvement. This article is protected by copyright. All rights reserved. This article is protected by copyright.

Signalling pathways involved in adult heart formation revealed by gene expression profiling in Drosophila.

Directory of Open Access Journals (Sweden)

Bruno Zeitouni

2007-10-01

Full Text Available Drosophila provides a powerful system for defining the complex genetic programs that drive organogenesis. Under control of the steroid hormone ecdysone, the adult heart in Drosophila forms during metamorphosis by a remodelling of the larval cardiac organ. Here, we evaluated the extent to which transcriptional signatures revealed by genomic approaches can provide new insights into the molecular pathways that underlie heart organogenesis. Whole-genome expression profiling at eight successive time-points covering adult heart formation revealed a highly dynamic temporal map of gene expression through 13 transcript clusters with distinct expression kinetics. A functional atlas of the transcriptome profile strikingly points to the genomic transcriptional response of the ecdysone cascade, and a sharp regulation of key components belonging to a few evolutionarily conserved signalling pathways. A reverse genetic analysis provided evidence that these specific signalling pathways are involved in discrete steps of adult heart formation. In particular, the Wnt signalling pathway is shown to participate in inflow tract and cardiomyocyte differentiation, while activation of the PDGF-VEGF pathway is required for cardiac valve formation. Thus, a detailed temporal map of gene expression can reveal signalling pathways responsible for specific developmental programs and provides here substantial grasp into heart formation.

A case of exorbitism in association with Wegener′s granulomatosis with renal involvement

Directory of Open Access Journals (Sweden)

S Beji

2012-01-01

Full Text Available Wegener′s granulomatosis (WG is a necrotizing granulomatous vasculitis invol-ving the nose, paranasal sinuses, lungs, and kidneys. Ocular involvement can occur in about 50% of cases. There are very few reports of WG with orbital inflammation and exorbitism. We report a case of a female patient who presented with exorbitism related to orbital inflammation secondary to WG, with renal involvement. A 29-year-old woman with a previous history of recurrent pan-sinusitis presented with bilateral exophthalmos and renal failure with rapidly progressive glo-merulonephritis. Computed tomography showed extensive bilateral soft tissue in the retro-orbital area. Immunologic tests showed the presence of type-C anti-neutrophil cytoplasmic antibodies and renal biopsy revealed pauci immune crescentic glomerulonephritis. The patient was treated with corticosteroids and pulses of cyclophosphamide followed by azathioprine and trimethoprim-sulfamethoxazole. After a follow-up of 10 months, the renal outcome was favorable with improvement of renal function but there was persistence of exorbitism and loss of visual function. Our case suggests that WG should be considered in the differential diagnosis of persistent bila-teral exophthalmos. Prompt recognition of this early manifestation is important for the institution of early treatment.

Pemphigus, defines a group of disorders in autoimmune etiology which could be life-threatening and clinical manifestations are mainly epithelial blistering affecting cutaneous and/or mucosal surfaces including oral mucosa. The aim of our study is to evaluate the clinical appearance of pemphigus with oral involvement by reported 15 pemphigus cases. This retrospective study of 15 cases of pemphigus obtained over a period of 7 years from 2006 to 2013 in Istanbul University, Dentistry Faculty, Oral Medicine and Surgery Department was designed. Age distribution of pemphigus was from 15 to 59 years with an average age of 41.3 years. Of the 15 patients, the male:female ratio was 1:2.75 (4 male, 11 female). The most common clinical various of pemphigus was pemphigus vulgaris, diagnosed in all patients. The buccal mucosa (34.3%) was the most commonly affected site followed by tongue (20%), gingiva (17.1%), palate (11.4%), lips (11.4%) and floor of mouth (5.7%). Our explanation of this conclusion, while speculative, is that socioeconomic situation related stress in males and hormonal changes like pregnancy and menostasis in females; systemic disease and using drugs; dental trauma and bruxism could be responsible for flare up in the disease.

2015-01-01

Full Text Available Introduction. Eosinophilic polymyositis (EPM is a rare cause of rhabdomyolysis characterized by eosinophilic infiltrates in the muscle. We describe the case of a young patient with eosinophilic polymyositis causing isolated severe rhabdomyolysis without systemic involvement. Case Presentation. A 22-year-old Haitian female with no past medical history presented with progressive generalized muscle aches without precipitating factors. Examination of the extremities revealed diffuse muscle tenderness. Laboratory findings demonstrated peripheral eosinophilia and high creatinine phosphokinase (CPK and transaminase levels. Workup for the common causes of rhabdomyolysis were negative. Her CPK continued to rise to greater than 100,000 units/L so a muscle biopsy was performed which showed widespread eosinophilic infiltrate consistent with eosinophilic polymyositis. She was started on high dose systemic corticosteroids with improvement of her symptoms, eosinophilia, and CPK level. Discussion. This case illustrates a systematic workup of rhabdomyolysis in the presence of peripheral eosinophilia. Many differential diagnoses must be considered before establishing a diagnosis of idiopathic eosinophilic polymyositis. To our knowledge, our case of eosinophilic polymyositis is unique as it presented with severe rhabdomyolysis without another organ involvement. Clinicians should maintain a high index of suspicion for this physically debilitating disease to aid in prompt diagnosis.

Neuropsychological profile of a Filipino gentleman with X-linked dystonia-parkinsonism: a case report of Lubag disease.

X-Linked Dystonia-Parkinsonism (XDP or "Lubag") is a progressive neurodegenerative disorder unique to the Island of Panay in the Philippines. Imaging and autopsy studies have suggested involvement of the caudate and putamen in late stages. Because the clinical presentation of patients with XDP resembles that of patients with Parkinson disease or dystonia, it is reasonable to predict the neuropsychological profile might be similar; however, the neuropsychological profile of a XDP patient has not previously been published. We present the neuropsychological findings of a 67-year-old gentleman with a 10-year history of XDP who presented with parkinsonian and dystonic symptoms. He was evaluated for suitability for deep brain stimulation surgery. Neuropsychological findings demonstrated diffuse impairment involving memory, visuospatial, language, and executive functioning.

CNS dengue infection is a rare condition and the pattern of brain involvement has not been well described. We report the MR imaging (MRI) features in eight cases of dengue encephalitis. We retrospectively searched cases of dengue encephalitis in which imaging was performed. Eight cases (three men, five women; age range: 8-42 years) diagnosed with dengue encephalitis were included in the study. MR studies were performed on 3-T and 1.5-T MR clinical systems. Two neuroradiologists retrospectively reviewed the MR images and analysed the type of lesions, as well as their distribution and imaging features. All eight cases exhibited MRI abnormalities and the cerebellum was involved in all cases. In addition, MRI signal changes were also noted in the brainstem, thalamus, basal ganglia, internal capsule, insula, mesial temporal lobe, and cortical and cerebral white matter. Areas of susceptibility, diffusion restriction, and patchy post-contrast enhancement were the salient imaging features in our cohort of cases. A pattern of symmetrical cerebellar involvement and presence of microbleeds/haemorrhage may serve as a useful imaging marker and may help in the diagnosis of dengue encephalitis. (orig.)

2009-07-01

Full Text Available Abstract Background Serial analysis of gene expression (LongSAGE was applied for gene expression profiling in seeds of oilseed rape (Brassica napus ssp. napus. The usefulness of this technique for detailed expression profiling in a non-model organism was demonstrated for the highly complex, neither fully sequenced nor annotated genome of B. napus by applying a tag-to-gene matching strategy based on Brassica ESTs and the annotated proteome of the closely related model crucifer A. thaliana. Results Transcripts from 3,094 genes were detected at two time-points of seed development, 23 days and 35 days after pollination (DAP. Differential expression showed a shift from gene expression involved in diverse developmental processes including cell proliferation and seed coat formation at 23 DAP to more focussed metabolic processes including storage protein accumulation and lipid deposition at 35 DAP. The most abundant transcripts at 23 DAP were coding for diverse protease inhibitor proteins and proteases, including cysteine proteases involved in seed coat formation and a number of lipid transfer proteins involved in embryo pattern formation. At 35 DAP, transcripts encoding napin, cruciferin and oleosin storage proteins were most abundant. Over both time-points, 18.6% of the detected genes were matched by Brassica ESTs identified by LongSAGE tags in antisense orientation. This suggests a strong involvement of antisense transcript expression in regulatory processes during B. napus seed development. Conclusion This study underlines the potential of transcript tagging approaches for gene expression profiling in Brassica crop species via EST matching to annotated A. thaliana genes. Limits of tag detection for low-abundance transcripts can today be overcome by ultra-high throughput sequencing approaches, so that tag-based gene expression profiling may soon become the method of choice for global expression profiling in non-model species.

A case for increased private sector involvement in Ireland's national animal health services.

More, Simon J

2008-02-01

Non-regulatory animal health issues, such as Johne's disease, infectious bovine rhinotracheitis (IBR) and mastitis will become increasing important, with ongoing globalisation of markets in animals and animal products. In response, Ireland may need to broaden the scope of its national animal health services. However, there have been concerns about the respective roles and responsibilities (both financial and otherwise) of government and industry in any such moves. This paper argues the case for increased private sector involvement in Ireland's national animal health services, based both on theoretical considerations and country case studies (the Netherlands and Australia). The Dutch and Australian case studies present examples of successful partnerships between government and industry, including systems and processes to address non-regulatory animal health issues. In each case, the roles and responsibilities of government are clear, as are the principles underpinning government involvement. Furthermore, the roles and responsibilities (financial and otherwise) of the Dutch and Australian industry are determined through enabling legislation, providing both legitimacy and accountability. There are constraints on the use of EU and national government funds to support non-regulatory animal health services in EU member states (such as Ireland and the Netherlands).

Full Text Available Abstract Non-regulatory animal health issues, such as Johne's disease, infectious bovine rhinotracheitis (IBR and mastitis will become increasing important, with ongoing globalisation of markets in animals and animal products. In response, Ireland may need to broaden the scope of its national animal health services. However, there have been concerns about the respective roles and responsibilities (both financial and otherwise of government and industry in any such moves. This paper argues the case for increased private sector involvement in Ireland's national animal health services, based both on theoretical considerations and country case studies (the Netherlands and Australia. The Dutch and Australian case studies present examples of successful partnerships between government and industry, including systems and processes to address non-regulatory animal health issues. In each case, the roles and responsibilities of government are clear, as are the principles underpinning government involvement. Furthermore, the roles and responsibilities (financial and otherwise of the Dutch and Australian industry are determined through enabling legislation, providing both legitimacy and accountability. There are constraints on the use of EU and national government funds to support non-regulatory animal health services in EU member states (such as Ireland and the Netherlands.

Full Text Available The aim of this study was to examine the relationship between motivational characteristics and dispositional flow. In order to accomplish this goal, motivational profiles emerging from key constructs within Achievement Goal Theory and Self-Determination Theory were related to the dispositional flow measures. A sample of 413 young athletes (Age range 12 to 16 years completed the PMCSQ-2, POSQ, SMS and DFS measures. Cluster analysis results revealed three profiles: a "self-determined profile" characterised by higher scores on the task-involving climate perception and on the task orientation; a "non-self-determined profile", characterised by higher scores on ego-involving climate perception and ego orientation; and a "low self-determined and low non-self-determined profile" which had the lowest dispositional flow. No meaningful differences were found between the "self-determined profile" and the "non-self-determined profile" in dispositional flow. The "self-determined profile" was more commonly associated with females, athletes practising individual sports and those training more than three days a week. The "non-self-determined profile" was more customary of males and athletes practising team sports as well as those training just two or three days a week

Aerosol extinction coefficient profile is an essential parameter for atmospheric radiation model. But it is difficult to get the full aerosol extinction profile from the ground to the tropopause especially in near ground precisely using backscattering lidar. A combined measurement of side-scattering, backscattering and Raman-scattering lidar is proposed to retrieve the aerosol extinction coefficient profile from the surface to the tropopause which covered a dynamic range of 5 orders. The side-scattering technique solves the dead zone and the overlap problem caused by the traditional lidar in the near range. Using the Raman-scattering the aerosol lidar ratio (extinction to backscatter ratio) can be obtained. The cases studies in this paper show the proposed method is reasonable and feasible.

Objective This study aimed to assess the risk factor profile of shoulder dystocia and associated neonatal complications in Oman, a developing Arab country. Methods A retrospective case-control study was conducted among 111 cases with dystocia and 111 controls, identified during 1994-2006 period in a tertiary care hospital in Oman. Controls were randomly selected among women who did not have dystocia, and were matched to cases on the day of delivery. Data related to potential risk factors, delivery, and obstetric complications were collected. Results Dystocia was significantly associated with older maternal age, higher parity, larger BMI, diabetes, and previous record of dystocia. In addition, dystocia was associated more with vacuum and forceps deliveries. Routine traction (51%) was the most used manoeuvre. Among dystocia cases, 13% were associated with fetal complications of which Erb’s Palsy was the most prevalent (79%). Conclusion Our finding of significant associations with risk factors lays out the ground to develop a predictability index for shoulder dystocia, which would help in making it preventable. Further p rospective studies are required to confirm the obtained results. PMID:25337307

2016-12-01

Patient and public involvement in all aspects of research is espoused and there is a continued interest in understanding its wider impact. Existing investigations have identified both beneficial outcomes and remaining issues. This paper presents the impact of public involvement in one case study led by a mental health charity conducted as part of a larger research project. The case study used a devolved model of working, contracting with service user-led organizations to maximize the benefits of local knowledge on the implementation of personalized budgets, support recruitment and local user-led organizations. To understand the processes and impact of public involvement in a devolved model of working with user-led organizations. Multiple data collection methods were employed throughout 2012. These included interviews with the researchers (n = 10) and research partners (n = 5), observation of two case study meetings and the review of key case study documentation. Analysis was conducted in NVivo10 using a coding framework developed following a literature review. Five key themes emerged from the data; Devolved model, Nature of involvement, Enabling factors, Implementation challenges and Impact. While there were some challenges of implementing the devolved model it is clear that our findings add to the growing understanding of the positive benefits research partners can bring to complex research. A devolved model can support the involvement of user-led organizations in research if there is a clear understanding of the underpinning philosophy and support mechanisms are in place. © 2015 The Authors.

Sarcoidosis is an inflammatory disorder that is characterized by the presence of noncaseating granulomas in tissues, involving many organs and tissues. Extra-pulmonary, especially muscular sarcoidosis is a rare condition. The most common location of the muscular sarcoidosis is known to be the proximal muscles of the extremities; however, there have been no cases of diffuse involvement of the chest and abdominal wall muscles. Here, we report a rare muscular sarcoidosis with infiltrative pattern in the chest and abdominal wall muscles and describe the MR imaging findings that were mistaken as lymphoma at initial diagnosis. Although our case did not show characteristic MR findings of muscular sarcoidosis, clinicians or radiologists who are aware of these imaging features can perform early systemic survey for sarcoidosis. Also muscle biopsy is very important to confirm the sarcoidosis and distinguish it from other tumors. (orig.)

Rutherford backscattering experiments under channeling conditions (RBS-c) have been carried out on Hg{sub 0.77}Cd{sub 0.23}Te (MCT) layers implanted with arsenic. Accurate damage profiles have been extracted through a simple formalism for implanted and annealed layers. Quantitative damage profiles are correlated with structural defects observed by bright-field scanning transmission electron microscopy (BF-STEM) and chemical composition measured by secondary ion mass spectrometry (SIMS). Evolution of damage for increasing ion implantation fluence has been investigated by these three complementary techniques. Evidence is found of irradiation induced annealing during implantation. A fast damage recovery has been observed for post-implantation thermal anneals. In the case of an implanted layer annealed during 1 h, the damage profile, associated with arsenic concentration measurements, indicates the presence of complexes involving arsenic.

Microscopic polyangiitis is characterized by pauci-immune, necrotizing small-vessel vasculitis and an anti-neutrophil cytoplasmic antibody-associated vasculitis. Although gastrointestinal involvement in microscopic polyangiitis is not rare, endoscopic observation of it is extremely rare. To the best of our knowledge, this is the first case report of small intestinal involvement in microscopic polyangiitis detected and followed up by double-balloon endoscopy. A 70-year-old Japanese woman was transferred to our hospital for close examination of suspected small intestinal lymphoma. Retrograde double-balloon endoscopy revealed various forms of ulcers with redness and edema in the ileum. Histological findings suggested ischemic changes. Because mononeuritis multiplex and a fever spike appeared later, vasculitis was suspected. The perinuclear anti-neutrophil cytoplasmic antibody titer was elevated. Nerve biopsy results suggested vasculitis. From these findings, microscopic polyangiitis was diagnosed. It was suggested that microscopic polyangiitis caused the intestinal involvement. Intravenous pulse cyclophosphamide and oral predonisolone were started. After treatment, perinuclear anti-neutrophil cytoplasmic antibodies decreased to the normal range. Retrograde double-balloon endoscopy after treatment showed ulcer scars and no ulcer. The cause of gastrointestinal involvement in microscopic polyangiitis is ischemia due to vasculitis. It is difficult to diagnose small-vessel vasculitis by endoscopic biopsy. Although histological evidence of microscopic polyangiitis is important, the treatment should not be delayed by repeating the biopsy, because such delay can result in adverse sequela.This case report shows that microscopic polyangiitis should be considered as a differential diagnosis when small intestinal changes like those in the present case are observed by endoscopy.

This paper presents a case study on the crude oil atmospheric distillation column of Tabriz refinery plant to show the applicability of exergy loss profiles in thermodynamic examination of the different retrofit options. The atmospheric distillation column of Tabriz refinery has been revamped as a consequence of increase of the plant capacity to 100,000 bpd. To cover the deficit of feedstock of the revamped unit, a blend of the existing feedstock with imported crude oil is used as a feedstock. However, to investigate how the blend of these two different types of crudes as a feedstock has an influence on the operating conditions, the examination of the column is needed. Exergy as a comprehensive thermodynamic property which translates the temperature, pressure and composition change into a common unit has been chosen to evaluate the distillation column thermodynamically. Furthermore, the exergy loss profile of the base case serves as a scoping tool to pinpoint the source of inefficiencies. Then, the exergy loss profile as a screening tool has found the retrofit options which are likely to yield greatest energy saving from a list of retrofit options proposed by the industrial partner. In the presented case study, the exergy loss profile identifies the best retrofit option with 17.16% reduction in exergy losses, which finally lead to 3.6% reduction of primary fuel demand. (orig.)

Full Text Available Abstract Background Penetrating injuries of the abdomen and spinal canal that involve organic material of animal origin are extremely rare and derive from domestic and wild animal attacks or fish attacks. Case presentation In this case report we present the unique, as far as the literature is concerned, unprovoked woman's injury to the abdomen by a swordfish. There are only four cases of swordfish attacks on humans in the literature - one resulted to thoracic trauma, two to head trauma and one to knee trauma, one of which was fatal - none of which were unprovoked. Three victims were professional or amateur fishermen whereas in the last reported case the victim was a bather as in our case. Our case is the only case where organic debris of animal's origin remained in the spinal canal after penetrating trauma. Conclusions Although much has been written about the management of penetrating abdominal and spinal cord trauma, controversy remains about the optimal management. Moreover, there is little experience in the management of patients with such spinal injuries, due to the fact that such cases are extremely rare. In this report we focus on the patient's treatment with regard to abdominal and spinal trauma and present a review of the literature.

1999-07-01

Full Text Available Three case studies involving Leptospira interrogans serovar pomona outbreaks within mixed farming systems in South Africa are described. On 2 farms, pigs constituted the main enterprise with cattle and sheep of secondary importance. On each of these 2 farms, abortion due to L. pomona in sows was confirmed by culture, and antibody titres to pomona were detected in cattle, sheep, horses and dogs. On the 3rd farm, a piggery was ofsecondary importance to cattle farming. Abortion and death in cows occurred on this farmand serology showed titres to various serovars, including pomona. L. pomona was also isolated from bovine urine, an aborted bovine foetus and kidneys from slaughtered pigs. This particular case study was regarded as clinically atypical in that adult Jersey cattle died of acute leptospirosis in a semiarid region of South Africa. In all 3 case studies, the poor management of pig effluent and of the drinking water and its sources played a pivotal role in the transmission of the disease. Inadequate vaccination of animals against Leptospira and poor record-keeping within the secondary farming enterprises were also contributing factors to the spread of leptospirosis.

Primary angiitis of the central nervous system is a rare condition, usually with an insidious onset. There is a wide variety of histological types (granulomatous, lymphocytic or necrotizing vasculitis) and types of vessel involved (arteries, veins or both). Most cases are idiopathic. We describe a first case of idiopathic granulomatous central nervous system phlebitis with additional limited involvement of the heart and lung, exclusively affecting small and medium sized veins in a 22-year-old woman, presenting as a sub acute headache. The reasons for this peculiar limitation of inflammation to the veins and the involvement of the heart and lungs are unknown. © 2015 Japanese Society of Neuropathology.

To report a case of primary angiitis of the central nervous system (PACNS), a rare inflammatory disease restricted to the central nervous system (CNS), with unusual clinical presentation mimicking schizophrenia. Case report. A 45-year-old male presented with alteration of consciousness and confusion. Brain magnetic resonance imaging (MRI) scan showed a mass-like enhancing lesion involving bilateral thalami, and biopsy revealed findings compatible with PACNS. The patient was treated with corticosteroids. Psychotic symptoms crystallized over the initial 2 months after the diagnosis and persisted for over a year. Severity of his symptoms improved with gradual normalization of the radiologic findings and antipsychotic medication. Our case highlights the importance of considering PACNS as a differential diagnosis of a tumor-like mass lesion in the CNS and the significance of thalamic involvement in the pathogenesis of psychotic symptoms including delusions and hallucinations.

MicroRNA profiling of primary cutaneous large B-cell lymphomas.

Directory of Open Access Journals (Sweden)

Lianne Koens

Full Text Available Aberrant expression of microRNAs is widely accepted to be pathogenetically involved in nodal diffuse large B-cell lymphomas (DLBCLs. However, the microRNAs profiles of primary cutaneous large B-cell lymphomas (PCLBCLs are not yet described. Its two main subtypes, i.e., primary cutaneous diffuse large B-cell lymphoma, leg type (PCLBCL-LT and primary cutaneous follicle center lymphoma (PCFCL are characterized by an activated B-cell (ABC-genotype and a germinal center B-cell (GCB-genotype, respectively. We performed high-throughput sequencing analysis on frozen tumor biopsies from 19 cases of PCFCL and PCLBCL-LT to establish microRNA profiles. Cluster analysis of the complete microRNome could not distinguish between the two subtypes, but 16 single microRNAs were found to be differentially expressed. Single microRNA RT-qPCR was conducted on formalin-fixed paraffin-embedded tumor biopsies of 20 additional cases, confirming higher expression of miR-9-5p, miR-31-5p, miR-129-2-3p and miR-214-3p in PCFCL as compared to PCLBCL-LT. MicroRNAs previously described to be higher expressed in ABC-type as compared to GCB-type nodal DLBCL were not differentially expressed between PCFCL and PCLBCL-LT. In conclusion, PCFCL and PCLBCL-LT differ in their microRNA profiles. In contrast to their gene expression profile, they only show slight resemblance with the microRNA profiles found in GCB- and ABC-type nodal DLBCL.

OBJECTIVES—Global aphasia without hemiparesis (GAWH) is an uncommon stroke syndrome involving receptive and expressive language impairment, without the hemiparesis typically manifested by patients with global aphasia after large left perisylvian lesions. A few cases of GAWH have been reported with conflicting conclusions regarding pathogenesis, lesion localisation, and recovery. The current study was conducted to attempt to clarify these issues.
METHODS—Ten cases of GAWH were prospectively studied with language profiles and lesion analysis; five patients had multiple lesions, four patients had a single lesion, and one had a subarachnoid haemorrhage. Eight patients met criteria for cardioembolic ischaemic stroke.
RESULTS—Cluster analysis based on acute language profiles disclosed three subtypes of patients with GAWH; these clusters persisted on follow up language assessment. Each cluster evolved into a different aphasia subtype: persistent GAWH, Wernicke's aphasia, or transcortical motor aphasia (TCM). Composite lesion analysis showed that persistent GAWH was related to lesioning of the left superior temporal gyrus. Patients with acute GAWH who evolved into TCM type aphasia had common lesioning of the left inferior frontal gyrus and adjacent subcortical white matter. Patients with acute GAWH who evolved into Wernicke's type aphasia were characterised by lesioning of the left precentral and postcentral gyri. Recovery of language was poor in all but one patient.
CONCLUSIONS—Although patients with acute GAWH are similar on neurological examination, they are heterogeneous with respect to early aphasia profile, language recovery, and lesion profile.

This article adds to the literature on familicide by providing specific insights from the Italian experience. It presents results of an exploratory investigation into male-perpetrated familicides in Italy between 1992 and 2015. Familicide is defined as the killing of the spouse or intimate partner, and at least one child, at the hand of the other spouse/partner. Incidents of familicide were collated from newspaper reports. We identified 90 cases, resulting in 207 deaths. On average, perpetrators were middle aged ( M = 46.8; age ranging from 25 to 76), and most ( n = 66; 73%) committed, or attempted to commit, suicide. While significant contributory roles were played by health problems and financial worries, the origin of the primary emotional upset for the killers tended to be interpersonal conflicts involving their partners. For those cases with available information ( n = 56; 62%), six types of familicide were also identified on the basis of the murderer's homicidal motivations. Most frequent were three circumstances. 15 cases concerned the "doubly-protective familicide" (which corresponds to the "suicide-by-proxy"), characterized by the preservation of the family in the face of a presumed catastrophic event. Triggers included the killer's financial distress, health troubles, or anxiety associated with other personal problems. 13 cases referred to "doubly-punitive familicide," whose distinctive feature, in addition to punishing the partner because of her estrangement, her infidelity, or other disputes, is to directly involve the child(ren) in the punitive homicidal act. The children are viewed as contributory factors to the killer's stress, or are considered to be in league with the mother. 12 cases exemplified "indirectly-punitive familicide" (also termed "murder-by-proxy"), in which the victimized child(ren) are killed as an extension of the partner. Overall, this typology provides a more nuanced conceptualization of familicide occurrences than those examined

Simple or unicameral bone cysts are metaphyseal lesions of long bones. They usually move away from the physis with growth to become diaphyseal in location. Involvement of the physis and epiphysis by these cystic lesions is very rare. This paper reports a case of simple bone cyst of the proximal humerus in a 11- year -old girl which was shown by MR imaging to extend through the physis into the epiphysis.

2006-05-21

Geographic profiling was originally developed as a statistical tool for use in criminal cases, particularly those involving serial killers and rapists. It is designed to help police forces prioritize lists of suspects by using the location of crime scenes to identify the areas in which the criminal is most likely to live. Two important concepts are the buffer zone (criminals are less likely to commit crimes in the immediate vicinity of their home) and distance decay (criminals commit fewer crimes as the distance from their home increases). In this study, we show how the techniques of geographic profiling may be applied to animal data, using as an example foraging patterns in two sympatric colonies of pipistrelle bats, Pipistrellus pipistrellus and P. pygmaeus, in the northeast of Scotland. We show that if model variables are fitted to known roost locations, these variables may be used as numerical descriptors of foraging patterns. We go on to show that these variables can be used to differentiate patterns of foraging in these two species.

Multiplex immunoassays are used for rapid profiling of biomarker proteins and small molecules in biological fluids. The advantages over single immunoassays include lower sample consumption, cost, and labor. This chapter details a protocol to develop a 5-plex assay for glucagon-like peptide 1, growth hormone, insulin, leptin, and thyroid-stimulating hormone on the Luminex ® platform. The results of the analysis of insulin in normal control subjects are given due to the important role of this hormone in nutritional programming diseases.

2009-06-01

Despite the genitourinary tract being the most common site affected by extrapulmonary TB, isolated testicular TB remains a rare clinical entity. In patients with co-morbidities such as hepatic impairment, treatment proves a challenge, as first-line hepatotoxic pharmaceuticals are contraindicated. Here, we report a case of isolated testicular TB with scrotal involvement, on a background of hepatic dysfunction.

Full Text Available Background and Objective: Dengue, an acute viral disease, transmitted by Aedes mosquitoes, has a variable clinical spectrum ranging from asymptomatic infection to life-threatening dengue hemorrhagic fever and dengue shock syndrome. However, neurological complications, in general, are unusual but have been observed more frequently in the recent past, and some studies highlighted varied neurological complications during the course of illness. Although dengue is classically considered a nonneurotropic virus, there is increasing evidence for dengue viral neurotropism. In this study, we have evaluated clinico-radiological profile and outcome of nine serologically confirmed dengue patients having varied manifestations of central nervous system (CNS involvement. Materials and Methods: All the consecutive patients presented with neurological complications with positive serology for dengue infection (IgM positivity in Department of Medicine, in a tertiary care hospital in Eastern India from August 2013 to October 2014 were included in the study. These patients were subjected to a detailed clinical evaluation, laboratory assessment including complete hemogram, coagulation profile, liver function test, serum electrolytes, and routine CSF (Cerebrospinal Fluid study with the exclusion of other common neuroinvasive pathogens. Results: Out of 9 patients with neurological complications associated with confirmed dengue infection, 2 (22% patients had dengue encephalopathy, 5 (56% patients have dengue encephalitis, 1 (11% patient had dengue meningitis, and 1 (11% patient had postdengue immune-mediated CNS involvement. Conclusion: This case series reaffirms the occurrence of varied CNS manifestations in dengue virus infection and underlines the importance of inclusion of dengue in the differential diagnosis of acute encephalitis syndrome.

2008-07-01

The development of HSE Cases demonstrating that HSE and particularly major accident hazard risks are being managed to an acceptable level is a requirement posed on many Oil and Gas facilities by regulators and stakeholders. In order to develop a demonstration case rather than a description and to ensure a truly live document, GASCO, one of the world's largest gas processing companies, turned to DNV to develop HSE Cases for all their facilities. The DNV approach included the use of Hazard and Effects Management Process (HEMP) and the development of a customised intranet solution to ensure a continuously living process. HEMP is a systematic method of identifying hazards, assessing risk, putting controls in place to guard against those risks and defining recovery measures should an incident happen. With GASCO, HEMP was implemented through workshops involving operation workforce from senior managers to supervisory level. A powerful and popular output of HEMP is the Bow Tie diagram which is used to graphically display HSE Critical Elements and the HSE Critical Activities and Tasks (i.e. operational systems) that support them. To ensure a living process, a dedicated GASCO intranet solution was developed where all users can easily access and contribute to the electronic HSE Case without any geographical constraints. The electronic case widens the user base and creates awareness among the workforce. The added value of the HEMP and intranet solution approach is that it focuses on capitalizing on knowledge and expertise present with those operating the facilities using a 'Cradle to the Grave' approach. It is essential to maximize the interface with the workforce in order to develop and maintain a comprehensive HSE Case. (author)

A case of disseminated hydatid disease by surgery involving multiple organs

2014-09-01

Full Text Available Hydatid disease is the most common parasitic infection in the world, and is caused by the parasite Echinococcus granulosus. The most common site of this disease is the liver (75%, followed by the lungs, kidney, bones, and brain. Multiple abdominal organ and peritoneal involvement can also be seen in some cases. The dissemination of hydatid cyst disease can develop spontaneously or secondary to trauma or surgery. Here, we present the case of a 69-year-old man with multiple cyst hydatidosis, who underwent surgery for acute appendicitis approximately 20 years previously. Computed tomography of the abdomen shows the multiple active and inactive cystic lesions in the liver, spleen, right kidney, and mesentery. This patient required surgery several times, as well as medical treatment, after the rupture of a mesenteric hydatid cyst during the appendectomy. Combined anthelmintic treatment was recommended to the patient who refused further surgical treatment.

Full Text Available Rheumatoid arthritis’ synovitis affects mostly small hand and feet joints, although it may compromise any joint with a synovial lining. Cervical involvement occurs usually in longstanding disease in over half of these patients. We report the case of a 35-year old male patient who was referred to our outpatient clinic for a 2-year severe and disabling inflammatory neck pain, with incomplete response to intramuscular non-steroidal anti-inflammatory drugs and unremarkable cervical imaging studies. He also mentioned self-limited episodes of symmetric polyarthralgia involving hands, wrists, elbows, knees and feet, which started after his cervical complaints. On laboratorial workup, positive rheumatoid factor and anti-citrullinated peptide antibody and negative HLA-B27 were found. Cervical spine magnetic resonance imaging revealed atlantoaxial subluxation and odontoid process inflammatory pannus and erosions. Rheumatoid arthritis with cervical spine involvement as initial manifestation of disease was the definite diagnosis. The patient was started on methotrexate and prednisone and he was referred to neurosurgery outpatient clinic for cervical spine fixation.

Full Text Available Abstract Objective To study the clinico-pathological characteristics of Langerhans cell sarcoma (LCS which involving epidermis. Methods A case of primary multifocal LCS was analyzed in histopathology and immunophenotype. Results A 41-year-old man with multifocal cutaneous LCS involving the inguina and waist was reported. Clinical and pathology data were available. Neoplastic cells with markedly malignant cytological features were observed. Tumor cells exhibited irregular shape with abundant and eosinophilic red staining cytoplasm; large, irregular-shaped, showing lobulated or dented nucleus and some cells with a longitudinal nuclear groove and prominent nucleoli. The tumor cells expressed CD1a, Langerin (CD207, S-100 protein, CD68 and vimentin, and did not express pan-T or B cell markers and epithelial markers. The patient died less than 1 year after diagnosis due to local recurrence and metastasis to the lung, despite the administration of local radiation and chemotherapy. Conclusions LCS is a tumor with markedly malignant cytological features that originates from Langerhans cells. Primary multifocal neoplasms involving epidermis is even rare. Accurate diagnosis is based on the histopathological and immunohistochemical of the tumor cells.

Full Text Available Abstract Introduction Sarcoidosis is an inflammatory disorder characterized by the presence of non-caseating granulomas in affected organs. The presence of CD4-positive T lymphocytes and macrophages in affected organs suggests an ongoing immune response. Systemic corticosteroids remain the mainstay of treatment, but therapy is often limited by adverse effects. This is the first report of the use of adalimumab (HUMIRA®, Abbott Laboratories, North Chicago, IL, USA, an anti-tumor necrosis factor monoclonal antibody, in a patient with systemic sarcoidosis with bone marrow involvement. Case presentation A 42-year-old African-American man with a medical history significant for hypertension and diabetes mellitus presented with anemia and thrombocytopenia of two months duration. The patient underwent physical examination, bone marrow aspiration and biopsy, chest X-ray, acid-fast bacilli stain, computed tomography with contrast, and additional laboratory tests. He was diagnosed with systemic sarcoidosis with splenomegaly and bone marrow involvement. Drug therapy included prednisone, which had to be discontinued owing to adverse effects, and adalimumab. Conclusion This is the first report describing the use of adalimumab in a patient with systemic sarcoidosis with bone marrow involvement. Tumor necrosis factor antagonism with adalimumab was efficacious and well-tolerated in this patient and may be considered as a treatment option for similar cases.

This is a case report of Churg-Strauss Syndrome (CSS) associated with cardiac involvement which is demonstrated in chest CT and cardiac MRI (CMR) without specific cardiac symptoms. A 32-year-old woman had a 3-year history of bronchial asthma, chronic sinusitis, and otitis media. The patient had various typical findings of CSS. The patient had no specific cardiac symptoms or signs such as chest pain, palpitations, syncope, or murmur, but she had diffuse low attenuation lesions in the inner wall of the left ventricle (LV) in contrast-enhanced CT. This corresponded to the area of subendocardial hyperenhancement in delayed contrast-enhanced CMR images. She was treated with steroids for 2 months. Follow-up delayed contrast-enhanced CMR of the LV showed a decrease in the size of the subendocardial enhancement area, and she had no symptoms. Therefore, the radiologist and clinician both should pay careful attention to observe possible cardiac involvement in case of CSS.

This gives an accurate view to programmers how close the worst execution path passing through a specific part of a real-time program...

Ombuds’ corner: Is the number of cases involving women related to their percentage in an organization?

CERN Multimedia

Vincent Vuillemin

2013-01-01

Over the past two years, the Ombuds has seen double the number of cases involving women staff members compared to those involving men, relative to their populations. Two questions can thus be asked: is that a general phenomenon also seen in other organizations? Or is it related to the under-representation of women, namely is this a common situation in organizations with fewer women than men? If so, the Ombuds should notice different statistics in organizations where the number of women and men is comparable.   To answer these questions, several annual reports from international organizations have been analysed. The names of these organizations are kept confidential, as the reports are not public. Relation between the percentage of cases involving women and their percentage in an Organization. The circled data point is CERN’s. The results can be seen in this graph (right), limited solely by the number of Organizations for which such data is available. Note that if the ...

How Irish 1985 Energy Demand Model (EDM) case study results have been optimized on the supply side, by means of the EFOM model and software, are described. The 1985 case study results are for low, likely, and high cases. The Low case represents a 1985 Irish economic profile for real GNP being 54% greater thand the GNP of 1974. The Likely case relates to 1985 real GNP being 70% greater than that of 1974, and the High to real GNP being 92% greater. The 1985 final energy results emerging from the case studies are tabulated, showing quantities of final energy required by each of the 13 sectors of the Irish EDM. In all three case studies, 5 of the 13 demand sectors take in aggregate more than 76% of the total energy; these five sectors, in decreasing size of demand, are: other household uses; other industries; private transport; cement; other services. The preparation for EFOM is described. The optimal final energy flows, with some comparisons with the non-optimal inital flows, are considered. The gross primary energy quantity and cost underlying the optimal final energy flows are examined in detail.

MYC translocation-negative classical Burkitt lymphoma cases: an alternative pathogenetic mechanism involving miRNA deregulation

Sarcoidosis is a chronic granulomatous disease that can affect multiple organs. The lungs, eyes, and skin are known to be highly affected organs in sarcoidosis. There have been reports based on random muscle biopsy that 32-80% of systemic sarcoidosis comprises noncaseating granulomas; however, muscle involvement in sarcoidosis is generally asymptomatic and has an unknown frequency. We describe a case of acute to subacute sarcoid myositis of the skeletal and extraocular muscles. Typical ophthalmic involvement (manifested by infiltration of the ocular adnexa, intraocular inflammation, or infiltration of the retrobulbar visual pathways) and extraocular sarcoid myositis (as with the present case) is infrequently reported. It is important to keep in mind the rare yet perhaps underestimated entity of sarcoid myositis, and to utilize muscle biopsy and imaging tests for appropriate diagnosis and management of patients with sarcoidosis.

Central nervous system (CNS) relapse occurs in around 5% of diffuse large B-cell lymphoma (DLBCL) cases. No biomarkers to identify high-risk patients have been discovered. We evaluated the expression of lymphocyte-guiding chemokine receptors in systemic and CNS lymphomas. Immunohistochemical staining for CXCR4, CXCR5, CCR7, CXCL12, and CXCL13 was performed on 89 tissue samples, including cases of primary central nervous system lymphoma (PCNSL), secondary CNS lymphoma (sCNSL), and systemic DLBCL. Also, 10 reactive lymph node samples were included. Immunoelectron microscopy was performed on two PCNSLs, one sCNSL, one systemic DLBCL, and one reactive lymph node samples, and staining was performed for CXCR4, CXCR5, CXCL12, and CXCL13. Chi-square test was used to determine correlations between clinical parameters, diagnostic groups, and chemokine receptor expression. Strong nuclear CXCR4 positivity correlated with systemic DLBCL, whereas strong cytoplasmic CXCR5 positivity correlated with CNS involvement (P = 0.003 and P = 0.039). Immunoelectron microscopy revealed a nuclear CXCR4 staining in reactive lymph node, compared with cytoplasmic and membranous localization seen in CNS lymphomas. We found that CNS lymphoma presented a chemokine receptor profile different from systemic disease. Our findings give new information on the CNS tropism of DLBCL and, if confirmed, may contribute to more effective targeting of CNS prophylaxis among patients with DLBCL. © 2015 John Wiley & Sons A/S.

An unusual presentation of brucellosis, involving multiple organ systems, with low agglutinating titers: a case report

Directory of Open Access Journals (Sweden)

Khorvash Farzin

2007-07-01

Full Text Available Abstract Background Brucellosis is a multi-system disease that may present with a broad spectrum of clinical manifestations. While hepatic involvement in brucellosis is not rare, it may rarely involve the kidney or display with cardiac manifestations. Central nervous system involvement in brucellosis sometimes can cause demyelinating syndromes. Here we present a case of brucella hepatitis, myocarditis, acute disseminated encephalomyelitis, and renal failure. Case presentation A 26-year-old man presented with fever, ataxia, and dysarthria. He was a shepherd and gave a history of low grade fever, chilly sensation, cold sweating, loss of appetite, arthralgia and 10 Kg weight loss during the previous 3 months. He had a body temperature of 39°C at the time of admission. On laboratory tests he had elevated level of liver enzymes, blood urea nitrogen, Creatinine, Creatine phosphokinase (MB, and moderate proteinuria. He also had abnormal echocardiography and brain MRI. Enzyme-linked immunosorbent assay for IgG and IgM was negative. Standard tube agglutination test (STAT and 2-mercaptoethanol (2-ME titers were 1:80 and 1:40 respectively. Finally he was diagnosed with brucellosis by positive blood culture and the polymerase chain reaction for Brucella mellitensis. Conclusion In endemic areas clinicians should consider brucellosis in any unusual presentation involving multiple organ systems, even if serology is inconclusive. In endemic areas low STAT and 2-ME titers should be considered as an indication of brucellosis and in these cases additional testing is recommended to rule out brucellosis.

Cognitive processes in criminal profile construction: a preliminary study.

Science.gov (United States)

Kocsis, Richard N; Middledorp, Jenny; Try, Andrew C

2005-12-01

This study undertook an empirically based examination of the cognitive processes associated with the accurate construction of a criminal psychological profile. This was accomplished by comparing the abilities of profilers and nonprofilers in two simulated profiling exercises that measured both profile accuracy and an individual's performance on various tests of memory and comprehension related to the case materials presented in each exercise. The results of these experiments suggest that an incremental relationship exists between comprehension of the case materials and accuracy of the profiles generated. In addition, the findings provide some tentative indications that the comprehension of case material in a narrative (i.e., written) format is an integral cognitive function to proficient profiling.

2002-01-01

Familial erythrophagocytic lymphohistiocytosis is a fatal early childhood disorder characterized by multiorgan lymphohistiocytic infiltration and active hemophagocytosis. Involvement of the central nervous system (CNS) is not uncommon and is characterized by rapidly progressive tissue damage affecting both the gray and white matter. We encountered a case of familial erythrophagocytic lymphohistiocytosis with CNS involvement. Initial T2-weighted MRI of the brain demonstrated high signal intensity in the right thalamus, though after chemotherapy, which led to the relief of neurologic symptoms, this disappeared. After four months. however, the patient's neurologic symptoms recurred, and follow-up T2-weighted MR images showed high signal intensity in the thalami, basal ganglia, and cerebral and cerebellar white matter. Brain MRI is a useful imaging modality for the evaluation of CNS involvement and monitoring the response to treatment

Histiocytic sarcoma with bladder involvement: Case report and literature review.

Science.gov (United States)

Fernández-Aceñero, Mª Jesús; Pérez Alonso, Pablo; Díaz Del Arco, Cristina

We report an unusual case of histiocytic sarcoma with bladder involvement. An 80 year-old man with a previous history of diffuse large B-cell malignant lymphoma presented with hematuria and back pain. Serial urine cytologies revealed no urothelial malignant cells, but cystoscopy showed a large intravesical mass. The patient underwent transurethral resection (TUR) of the tumor. The bladder TUR specimen showed a widely infiltrating epithelioid neoplasm, with intense immunohistochemical positivity for CD45 and histiocytic markers (CD68, lysozime and fascin). Histopathological diagnosis was histiocytic sarcoma. As the patient's condition was progressively deteriorating, only palliative care was indicated and he died one month after TUR. Although histiocytic sarcoma can often be widespread at the time of diagnosis, to our knowledge, this is the first report of a case presenting with urinary symptoms. Histiocytic sarcoma can mimic many other malignant lesions, and only immunohistochemistry can define the tumor cells, allowing correct therapy. We discuss the differential diagnosis and possible associations. Copyright © 2017 Sociedad Española de Anatomía Patológica. Publicado por Elsevier España, S.L.U. All rights reserved.

Full Text Available Mycoplasma synoviae (MS is an important pathogen of poultry worldwide, causing respiratory tract infection and infectious synovitis in chickens and turkeys. The study was designed to detect M. synoviae through serology, culture isolation and polymerase chain reaction (PCR assay to document the involvement of MS infection in respiratory distress cases of broiler birds. The validated PCR assay amplifying the conserved gene region of 16SrRNA gene was applied for the detection of M. synoviae from culture as well as in clinical samples. The results indicated that 04 out of total 17 commercial broiler flocks showing respiratory distress signs were found positive with M. synoviae infection indicating 76.57% sero-positivity as, determined with rapid serum agglutination (RSA test. Out of 85 clinical specimens (collected from sero-positive birds; M. synoviae culture isolation was successfully attained in 36 (42.35% samples. Whereas, PCR test has detected 84 (98.82% positive cases. The prevalence of MS in broiler birds was observed maximum as measured through PCR. It is suggested that the true prevalence of MS may best be reflected by combining RSA and PCR test findings.

2011-12-01

The emergence profile concept of an implant restoration is one of the most important factors for the esthetics and health of peri-implant soft tissue. This paper reports on two cases of gingival recontouring by the fabrication of a provisional implant restoration to produce an optimal emergence profile of a definitive implant restoration. After the second surgery, a preliminary impression was taken to make a soft tissue working cast. A provisional crown was fabricated on the model. The soft tissue around the implant fixture on the model was trimmed with a laboratory scalpel to produce the scalloped gingival form. Light curing composite resin was added to fill the space between the provisional crown base and trimmed gingiva. After 4 to 6 weeks, the final impression was taken to make a definitive implant restoration, where the soft tissue and tooth form were in harmony with the adjacent tooth. At the first insertion of the provisional restoration, gum bleaching revealed gingival pressure. Four to six weeks after placing the provisional restoration, the gum reformed with harmony between the peri-implant gingiva and adjacent dentition. Gingival recontouring with a provisional implant restoration is a non-surgical and non-procedure-sensitive method. The implant restoration with the optimal emergence profile is expected to provide superior esthetic and functional results.

To evaluate myocardial involvement in diabetes mellitus, we studied 39 patients with negative double-Master's test and without hypertension by exercise thallium-201 (Tl-201) myocardial scintigraphy using a bicycle ergometer. Among the 39 patients, 12 (30.8 %) showed filling defects in the scintigrams (positive cases), including eight with stress-induced defects and four with fixed defects. The positive cases had higher scores of diabetic complications (3.6 +- 2.4 vs 2.1 +- 1.8; p < 0.05) and longer durations of diabetes as compared with those of the negative cases. The frequency of insulin therapy was also greater in the positive cases. Eleven patients (5 positive and 6 negative cases) who underwent cardiac catheterization had no significant stenotic lesions of their coronary arteries. However, all of the positive cases showed abnormal wall motion, mainly hypokinesis, by left ventriculography (LVG). The abnormalities of the LVG corresponded to the findings of the scintigrams (i.e. filling defects and decrease in washout ratios by circumferential profile analysis). These results suggest that in some diabetics myocardial involvement exists in the early stage without overt cardiac disease and exercise Tl-201 scintigraphy is useful in detecting pre-clinical cardiomyopathy. Cardiomyopathy in diabetics seems to be due to disturbances of the myocardial microcirculation. (author)

Intelligent sensors for evaluating reservoir and well profiles in horizontal wells : Saudi Arabia case histories

Horizontal wells are commonly used in Saudi Arabia because they have proven advantages in optimizing production and cost. However, in order to ensure proper production, these wells occasionally require downhole measurements of the flow profile; wellbore parameters such as water entry points; and productivity index for remedial action, such as water shut off or well stimulation. Evaluating the performance of a well also contributes to a better understanding of sweep, water production and cross flow, particularly in long reach wells. The most common flow regime at downhole conditions is a stratified flow regime in which lighter oil flows on top and heavier water flows on bottom. Slugging and bubbling flow regimes are typical of low oil flow rate and are considered unstable flow regimes. This paper described a new generation of production logging tools (PLTs) that have been used on some horizontal wet producers located in Saudi Arabia. The new PLTs consists of arrays of spinners and sensors to log the entire cross section to describe the horizontal flow regime and measure the downhole production and phases. In an effort to find the best logging procedure, the PLT was tested using two methods, notably coiled tubing (CT) and wireline tractor. It was concluded that PLTs are reliable and accurate. Case studies involving planning, deployment, data acquisition, and detailed analysis of PLTs were presented. 35 refs., 1 tab., 20 figs.

Each forensic case is characterized by its own uniqueness. Deficient forensic cases require additional sources of human identifiers to assure the identity. We report on two different cases illustrating the role of teeth in answering challenging forensic questions. The first case involves identification of an adipocere male found in a car submersed in water for approximately 2 years. The second scenario, which involves paternity DNA testing of an exhumed body, was performed approximately 2.8 years post-mortem. The difficulty in anticipating the degradation of the DNA is one of the main obstacles. DNA profiling of dental tissues, DNA quantification by using real-time PCR (PowerQuant™ System/Promega) and a histological dental examination have been performed to address the encountered impediments of adverse post-mortem changes. Our results demonstrate that despite the adverse environmental conditions, a successful STR profile of DNA isolated from the root of teeth can be generated with respect to tooth type and apportion. We conclude that cementocytes are a fruitful source of DNA. Cementum resists DNA degradation in comparison to other tissues with respect to the intra- and inter-individual variation of histological and anatomical structures.

Epileptic Electroencephalography Profile Associates with Attention Defects in Children with Fragile X Syndrome: review and case series

Directory of Open Access Journals (Sweden)

Benjamin Cowley

2016-07-01

Full Text Available Fragile X syndrome (FXS is the most common cause of inherited intellectual disability and a variant of autism spectrum disorder (ASD. The FXS population is quite heterogeneous with respect to comorbidities, which implies the need for a personalized medicine approach, relying on biomarkers or endophenotypes to guide treatment. There is evidence that quantitative electroencephalography (EEG endophenotype-guided treatments can support increased clinical benefit by considering the patient’s neurophysiological profile. We describe a case series of 11 children diagnosed with FXS, aged one to 14 years, mean 4.6 years. Case data are based on longitudinal clinically-observed reports by attending physicians for comorbid symptoms including awake and asleep EEG profiles. We tabulate the comorbid EEG symptoms in this case series, and relate them to the literature on EEG endophenotypes and associated treatment options. The two most common endophenotypes in the data were diffuse slow oscillations and epileptiform EEG, which have been associated with attention and epilepsy respectively. This observation agrees with reported prevalence of comorbid behavioral symptoms for FXS. In this sample of FXS children, attention problems were found in 37% (4 of 11, and epileptic seizures in 45% (5 of 11. Attention problems were found to associate with the epilepsy endophenotype. From the synthesis of this case series and literature review, we argue that the evidence-based personalized treatment approach, exemplified by neurofeedback, could benefit FXS children by focusing on observable, specific characteristics of comorbid disease symptoms.

Central nervous system involvement in patients with HCV-related cryoglobulinemia: review and a case report

Directory of Open Access Journals (Sweden)

B. Canesi

2011-09-01

Full Text Available Introduction: Few well-documented cases of central nervous system involvement in patients with mixed cryoglobulinemia and/or HCV infection have been reported. We can distinguish between acute or subacute diffuse and focal lesions (transient ischemic attack-like syndromes and cerebrovascular accidents. Methods: A search of two electronic databases (Medline and EMBASE was conducted from the year of their inception (1966 for Medline and 1988 for EMBASE to September 2000. The search strategy employed entailed combining these terms: Cryoglobulinemia, Central Nervous System, Hepatitis C, chronic hepatitis. Cryoglobulinemia and Central Nervous System were also used as free test words. We analysed articles with case reports and the most frequent articles on the references list. Pathogenesis: The main pathophysiologic mechanism of cerebral involvement is ischemia (or rarely hemorrhage due to diffuse or segmental vasculitis of the small cerebral vessels. In these cases a brain MRI usually shows single or multiple increased T2 signals. Furthermore an occasional occlusive vasculopathy without vasculitis was documented histologically. In these patients ischemia could be started or enhanced by the engorgement of the microvasculature by clumps of red cells and by aggregates of cryoglobulins. In the same patients vasculitis and hemoreological abnormalities can affect the clinical picture of the cerebral involvement in mixed cryoglobulinemia. Finally, the detection of HCV in the lesions induces a hypothesis that, in some cases, CNS involvement could be directly related to chronic HCV infection, even in the absence of cryoglobulin production. Case report: We describe a 63 year-old woman with acute severe encephalopathy. Laboratory evaluation revealed a high positive test result for rheumatoid factor (3390 U/ml and hypocomplementemia (C4 less than 1.67 mg/dl. Protein immunofixation electrophoresis demonstrated 5% monoclonal proteins (IgM/k and IgG/k, 3

Profile of sudden death in an adult population (1999-2008).

Sudden death is the sudden and unexpected death of an individual within 24 hours of symptom onset. The vast majority of these cases are found, at autopsy, to be due to underlying ischaemic cardiac disease. We retrospectively reviewed all adult post mortems performed at Beaumont Hospital over a decade (1999-2008). Our aim was to identify all sudden death cases (natural and accidental) and subclassify them according to age profile and organ system involved. We identified 1230 sudden death cases in the review period with 775 (63%) deaths attributable to ischaemic heart disease. The rate of sudden death remained constant over the decade with 663 (54%) deaths occurring in the first five years. Our negative autopsy rate was 2.8% corresponding to 35 cases. This is the first Irish study to retrospectively review all adult sudden deaths within a defined catchment area and analyse them as outlined above.

The absorption and emission arrays in the unresolved transition array (UTA) and super transition array (STA) models are usually assumed to have the same Gaussian spectral shape. It is shown, starting from a Boltzmann population distribution, that the assumption of profile identity for both absorption and emission is inconsistent with Kirchhoff's law. A correcting formula is established. It is extended to the cases where one or two effective population temperatures are involved. Examples are shown where the effect is noticeable.

Full Text Available Joint involvement in syphilis has been considered as casuistry in recent years. At the same time, the high incidence of primary syphilis and the notified cases of late neurosyphilis may suggest that joint involvement in this disease is by no means always verified. Traditionally there are two forms of syphilitic arthritis: primary synovial (involving the articular membranes and sac and primary bone (involving the articular bones and cartilages ones. The paper describes the authors' clinical case of the primary bone form of articular syphilis in a 34-year-old man.

Full Text Available Objective: Serum lipid levels are not only associated with etiology, but also with prognosis in cancer. To investigate this issue further, we aimed to evaluate the serum levels of lipids in association with the most important prognostic indicators in cancer patients at the start of chemotherapy. Methods: In a retrospective cross-sectional study, using existing medical records obtained from 2009–2014, the data of all incident cancer cases in Iranian patients referred to the Semnan oncology clinic for chemotherapy were analyzed. Data on demographics, cancer type, prognostic indicators (e.g. lymph node involvement, metastasis, and stage of disease, as well as the patient’s lipid profile were collected. We used multiple logistic regression models to show the relationship between prognosis indicators and lipid profile adjusting for age, gender, and type of cancer. Results: The data of 205 patients was gathered. We found a significant difference in the lipid profile between different types of cancers (breast, colon, gastric, and ovarian. With the exception of high-density lipoprotein levels in women, which were higher than in men, the means of other lipid profiles were similar between the genders. There was a significant association between higher levels of low-density lipoprotein (LDL >110mg/dL in the serum and metastasis (adjusted odds ratio=2.4, 95% CI 1.2–3.5. No significant association was reported between lipid profile and lymph nodes involvement and stage of the disease. Conclusion: Our study suggested a benefit of measuring serum levels of lipids for predicting cancer progression. Increased LDL levels can be considered a predictive factor for increasing the risk of metastasis.

2011-12-01

We present a rare case of a very rapidly growing stage IV ovarian endometrioid adenocarcinoma involving the uterine cervix and vagina without lymph node involvement. A 43-year-old woman visited the hospital with complaints of lower abdominal discomfort and vaginal bleeding over the previous 3 months. Serum levels of tumor marker CA 125 and SCC antigen (TA-4) were normal. On magnetic resonance imaging, a 7.9×9.7cm heterogeneous mass with intermediate signal intensity was observed in the posterior low body of the uterus. Two months ago, a computed tomography scan revealed an approximate 4.5×3.0cm heterogeneously enhanced subserosal mass with internal ill-defined hypodensities. A laparotomy, including a total abdominal hysterectomy with resection of the upper vagina, bilateral salpingo-oophorectomy, pelvic and para-aortic lymph node dissection, appendectomy, total omentectomy, and biopsy of rectal serosa was performed. A histological examination revealed poorly differentiated endometrioid ovarian adenocarcinoma with vaginal involvement. The patient had an uncomplicated post-operative course. After discharge, she completed six cycles of adjuvant chemotherapy with paclitaxel (175mg/m(2)) and carboplatin (300mg/m(2)) and has remained clinically disease-free until June 2010. Epithelial ovarian cancer may grow very rapidly. The frequent measurement of tumor size by ultrasonography may provide important information on detection in a subset of ovarian carcinomas that develop from preexisting, detectable lesions.

Existence and Stability of Viscous Shock Profiles for 2-D Isentropic MHD with Infinite Electrical Resistivity

Blake, B.; Zumbrun, K.; Lafitte, O.

2010-01-01

For the two-dimensional Navier Stokes equations of isentropic magnetohydrodynamics (MHD) with γ-law gas equation of state, γ≥1, and infinite electrical resistivity, we carry out a global analysis categorizing all possible viscous shock profiles. Precisely, we show that the phase portrait of the Crave ling-wave ODE generically consists of either two rest points connected by a viscous Lax profile, or else four rest points, two saddles and two nodes. In the latter configuration, which rest points are connected by profiles depends on the ratio of viscosities, and can involve Lax, over-compressive, or under-compressive shock profiles. Considered as three-dimensional solutions, under-compressive shocks are Lax-type (Alfven) waves. For the monatomic and diatomic cases γ=5/3 and γ=7/5, with standard viscosity ratio for a nonmagnetic gas, we find numerically that the the nodes are connected by a family of over-compressive profiles bounded by Lax profiles connecting saddles to nodes, with no under-compressive shocks occurring. We carry out a systematic numerical Evans function analysis indicating that all of these two-dimensional shock profiles are linearly and nonlinearly stable, both with respect to two- and three-dimensional perturbations. For the same gas constants, but different viscosity ratios, we investigate also cases for which under-compressive shocks appear; these are seen numerically to be stable as well, both with respect to two-dimensional and (in the neutral sense of convergence to nearby Riemann solutions) three-dimensional perturbations.

Objective To analyze cases of violence against transvestites and transsexuals based on their sociodemographic profile. Method Cross-sectional, descriptive research performed in Cajazeiras / Paraíba, consisting of 16 transvestites and transsexuals. Data collection took place in April 2014 and was analyzed descriptively. Results The typology of violence that victimized transvestites and transsexuals were: verbal (91.96%), psychological (58.33%) and physical (33.33%), often between 24 hours and six months preceding the survey. Regarding the spatiality: the street, school and health services were all scenarios of aggression. With respect to the offending agent, the findings point towards neighbors, family members and health professionals. All forms of violence happened between agents and spaces of aggression. Conclusions Violence among this population, silence around the situations of abuse became more pronounced as did its invisibility in the social and institutional context, reflecting the inhibition of human rights and concealment of reality.

It is good practice for the public to be involved in developing health research. Resources should be available for researchers to fund the involvement of the public in the development of their grants. To describe a funding award scheme to support public involvement in grant development, managed by an NIHR Research Design Service (RDS). Case examples of how the award contributed to successful grant applications and findings from a recent evaluation of the scheme are presented. A case study of resource provision to support public involvement activities in one region of England. University and NHS-based researchers, and members of the public. Between 2009 and 2012, the RDS approved 45 public involvement funding awards (totalling nearly £19,000). These awards contributed to 27 submitted applications at the time of writing, of which 11 were successful (totalling over £7.5 million). The evaluation revealed difficulties encountered by some researchers when involving the public in grant development, which led to suggestions about how the scheme could be improved. This award scheme represents an efficient method of providing researchers with resources to involve the public in grant development and would appear to represent good value for money. © 2013 John Wiley & Sons Ltd.

Langerhans cell histiocytosis (LCH) is systemic disease resulting from the proliferation and dissemination of abnormal histiocytic cells of the Langerhans cell system. Common sites of involvement include the skin, bone, bone marrow, lung, lymph nodes and central nervous system, and the condition manifests in variety of ways. We present the CT and MR findings of a case of LCH involving the spleen, an organ invloved relatively rarely. Post-contrast CT revealed multiple hypodense nodules. T1-weighted MR images of the spleen depicted no definitive lesion, but T2-weighted images showed abnormal low signals scattered throughout this organ. In addition, post-contrast, fat-saturated T1-weighted MR images lesions showed multiple, low-signal-intensity lesions.

Heena M Desai

2015-01-01

Full Text Available Mitral valve prolapse (MVP is usually asymptomatic, but can be associated with complications such as infective endocarditis, mitral regurgitation, thromboembolism and sudden cardiac death. It has been very rarely reported to occur in association with other valvular involvement. A 55-year-old male patient was brought dead and at autopsy the mitral valve orifice was stenotic and the leaflets were enlarged, myxoid and bulging suggestive of MVP and chordae tendinae were thickened, stretched and elongated. Similar changes were seen in the tricuspid valve. The pulmonary and aortic valves also showed myxomatous degeneration of their cusps. Myxomatous degeneration is the most common cause of MVP and it can be associated with involvement of the other valves. Concomitant involvement of the aortic valve has been reported, however it is very rare and simultaneous involvement of the pulmonary valve has not been reported in the literature so far. We report a case of MVP associated with myxomatous degeneration of the tricuspid, pulmonary and aortic valves.

Cervical spondylolysis is a rare condition, and less than 100 cases have been reported in the world literature. Cervical spondylolysis is defined as a well corticated defect in the posterior element of a cervical vertebra. Although the etiology of cervical spondylolysis is unknown, its association with dysplastic changes and spina bifida occulta suggest that the lesion is congenital. Here, we describe the radiographs and CT images of cervical spondylolysis involving four levels in a 9 year old boy.

The authors aimed to (a) identify the cognitive appraisals underlying nostalgia and (b) compare nostalgia with other emotions in terms of its appraisal profile. In Study 1, participants (N = 1,125) generated narratives. Next, they reported the level of nostalgia and 31 other emotions that these narratives elicited. Subsequently, participants evaluated the narrative events on several cognitive appraisals. Events that elicited nostalgia were pleasant, involved an irretrievable loss, felt psychologically distant, and were unique-an appraisal profile that differed from all other emotions. In Study 2 (N = 1,261), the authors experimentally varied these appraisals in a vignette paradigm and measured anticipated nostalgia and 10 other emotions. Participants anticipated most nostalgia when events were pleasant, involved irretrievable loss, were distant, and were unique-a profile shared only with longing. In Study 3 (N = 994), the authors used a guided autobiographical recall procedure in which they manipulated appraisals and measured the resultant emotions. Corroborating Studies 1-2, nostalgia was most intense for events that were pleasant, irretrievably lost, temporally distant, and unique. This appraisal profile was not shared by other emotions. The findings delineate the distinguishing cognitive appraisal profile of nostalgia. Nostalgia occupies a special place in the pantheon of emotions.

A Case of Midbrain and Thalamic Infarction Involving Artery of Percheron

Directory of Open Access Journals (Sweden)

Muhammad Almamun

2015-03-01

Full Text Available Blood supply to the thalamus and brainstem have frequent anatomic variations. One of these is where all the perforators to the above areas arise from a single branch of the posterior cerebral artery commonly known as the artery of Percheron. Infarction involving this artery leading to bilateral thalamic and midbrain lesions is not uncommon, but can cause diagnostic difficulties due to the varying clinical presentations possible and the wide differentials. Early brain imaging and diagnosis is important for initiating appropriate treatment. In this case report, we discuss a patient who presented with an artery of Percheron related stroke affecting the mid brain and paramedian thalamic areas. We also discuss the differentials of presentations with similar symptoms.

EMPLOYEE INVOLVEMENT IN A CHANGE PROCESS - A CASE STUDY FOR ROMANIAN ORGANIZATIONS

Full Text Available Innovation, competitive advantage, change are some concepts that should be on every organization's agenda, due to the fact the global market leads to global competition so in order to increase the market share, turnover or profit organizations have to incorporate those concepts in their strategies. The outside environment is very unstable and things are evolving very fast so managers from all levels have to acknowledge the importance of change and to identify as soon as possible several new ideas that should be the subject of different change processes. Openness to organizational change has become a mandatory feature for those organizations that want to survive and adapt to the external pressure, helping them to be efficient. Even if in many cases managers are the initiators of change, this process is very complex and needs support and involvement from all the members of the organization, so the employee's attitude and commitment to change is crucial. In many cases employees have a negative attitude towards change and manifest a strong resistance, due to the fact that they are not consulted and are not involved in the process of the identification for the need of change. Without understanding and knowing very well what it is expected from them, employees are afraid of the unknown and prefer to perform their tasks as they did before. Creating a climate and a culture for change is very important, because like this change will be something normal, continuous and people will feel comfortable with any change initiatives, without being surprised, confused or scared. Even if any change process should improve the current state of the organization, sometimes change efforts fail because the ones that resist change are stronger than the ones supporting change. The purpose of this paper is to analyze how often are Romanian employees involved in the processes of change and how important is the role they play. We have also tried to see the Romanian manager

In environmental forensic, it is extremely important to have a fast and reliable method in identifying sources of spilled oil and petroleum products. In this study, solid phase micro extraction (SPME) method coupled to gas chromatography-mass spectrometry was developed for the analysis of hydrocarbons in diesel and petroleum contaminated soil samples. Optimization of SPME parameters such as extraction time, extraction temperature and desorption time, was performed using 100-μm poly dimethylsiloxane (PDMS) fiber. These parameters were studied at three levels by means of a central composite experimental design and the optimum experimental conditions were determined using response surface method. The developed SPME method was applied to determine the profiles of hydrocarbons in several oil contaminated soil sample. The SPME method was also used to study the effects of weathering on the profiles of hydrocarbons in unleaded gasoline, diesel and kerosene contaminated soil samples. After several days, significant losses of the lighter hydrocarbons were observed compared to the heavier ones. From these data, SPME method can be used to differentiate possible candidate sources in oil spill cases. (author)

Ethnographic research among people who inject drugs (PWID) involves complex ethical issues. While ethical review frameworks have been critiqued by social scientists, there is a lack of social science research examining institutional ethical review processes, particularly in relation to ethnographic work. This case study describes the institutional ethical review of an ethnographic research project using observational fieldwork and in-depth interviews to examine injection drug use. The review process and the salient concerns of the review committee are recounted, and the investigators' responses to the committee's concerns and requests are described to illustrate how key issues were resolved. The review committee expressed concerns regarding researcher safety when conducting fieldwork, and the investigators were asked to liaise with the police regarding the proposed research. An ongoing dialogue with the institutional review committee regarding researcher safety and autonomy from police involvement, as well as formal consultation with a local drug user group and solicitation of opinions from external experts, helped to resolve these issues. This case study suggests that ethical review processes can be particularly challenging for ethnographic projects focused on illegal behaviours, and that while some challenges could be mediated by modifying existing ethical review procedures, there is a need for legislation that provides legal protection of research data and participant confidentiality.

Full Text Available Abstract Objective: The present study was aimed at investigating bone involvement secondary to rotator cuff calcific tendonitis at ultrasonography. Materials and Methods: Retrospective study of a case series. The authors reviewed shoulder ultrasonography reports of 141 patients diagnosed with rotator cuff calcific tendonitis, collected from the computer-based data records of their institution over a four-year period. Imaging findings were retrospectively and consensually analyzed by two experienced musculoskeletal radiologists looking for bone involvement associated with calcific tendonitis. Only the cases confirmed by computed tomography were considered for descriptive analysis. Results: Sonographic findings of calcific tendinopathy with bone involvement were observed in 7/141 (~ 5% patients (mean age, 50.9 years; age range, 42-58 years; 42% female. Cortical bone erosion adjacent to tendon calcification was the most common finding, observed in 7/7 cases. Signs of intraosseous migration were found in 3/7 cases, and subcortical cysts in 2/7 cases. The findings were confirmed by computed tomography. Calcifications associated with bone abnormalities showed no acoustic shadowing at ultrasonography, favoring the hypothesis of resorption phase of the disease. Conclusion: Preliminary results of the present study suggest that ultrasonography can identify bone abnormalities secondary to rotator cuff calcific tendinopathy, particularly the presence of cortical bone erosion.

Immunoglobulin G4 (IgG4)-related disease is a well-known disorder characterized by an inflammatory reaction with an increase in the number of IgG4-positive plasma cells associated with sclerosis. IgG4-related disease often affects the dura mater with a pattern of diffuse thickening when the central nervous system is involved. However, some nodular dural thickening requires discrimination from tumors because of obviously different treatment options. We report of a case of IgG4-related disease with tumefactive dural involvement

Outcome prediction models are widely used to evaluate trauma care. External benchmarking provides individual institutions with a tool to compare survival with a reference dataset. However, these models do have limitations. In this study, the hypothesis was tested whether specific injuries are associated with increased mortality and whether differences in case-mix of these injuries influence outcome comparison. A retrospective study was conducted in a Dutch trauma region. Injury profiles, based on injuries most frequently endured by unexpected death, were determined. The association between these injury profiles and mortality was studied in patients with a low Injury Severity Score by logistic regression. The standardized survival of our population (Ws statistic) was compared with North-American and British reference databases, with and without patients suffering from previously defined injury profiles. In total, 14,811 patients were included. Hip fractures, minor pelvic fractures, femur fractures, and minor thoracic injuries were significantly associated with mortality corrected for age, sex, and physiologic derangement in patients with a low injury severity. Odds ratios ranged from 2.42 to 2.92. The Ws statistic for comparison with North-American databases significantly improved after exclusion of patients with these injuries. The Ws statistic for comparison with a British reference database remained unchanged. Hip fractures, minor pelvic fractures, femur fractures, and minor thoracic wall injuries are associated with increased mortality. Comparative outcome analysis of a population with a reference database that differs in case-mix with respect to these injuries should be interpreted cautiously. Prognostic study, level II.

In the current study, the authors present a comprehensive genomic profile (CGP)-based study of advanced urothelial carcinoma (UC) designed to detect clinically relevant genomic alterations (CRGAs). DNA was extracted from 40 µm of formalin-fixed, paraffin-embedded sections from 295 consecutive cases of recurrent/metastatic UC. CGP was performed on hybridization-captured, adaptor ligation-based libraries to a mean coverage depth of 688X for all coding exons of 236 cancer-related genes plus 47 introns from 19 genes frequently rearranged in cancer, using process-matched normal control samples as a reference. CRGAs were defined as GAs linked to drugs on the market or currently under evaluation in mechanism-driven clinical trials. All 295 patients assessed were classified with high-grade (International Society of Urological Pathology classification) and advanced stage (stage III/IV American Joint Committee on Cancer) disease, and 294 of 295 patients (99.7%) had at least 1 GA on CGP with a mean of 6.4 GAs per UC (61% substitutions/insertions/deletions, 37% copy number alterations, and 2% fusions). Furthermore, 275 patients (93%) had at least 1 CRGA involving 75 individual genes with a mean of 2.6 CRGAs per UC. The most common CRGAs involved cyclin-dependent kinase inhibitor 2A (CDKN2A) (34%), fibroblast growth factor receptor 3 (FGFR3) (21%), phosphatidylinositol 3-kinase catalytic subunit alpha (PIK3CA) (20%), and ERBB2 (17%). FGFR3 GAs were diverse types and included 10% fusions. ERBB2 GAs were equally divided between amplifications and substitutions. ERBB2 substitutions were predominantly within the extracellular domain and were highly enriched in patients with micropapillary UC (38% of 32 cases vs 5% of 263 nonmicropapillary UC cases; PCancer 2016;122:702-711. © 2015 American Cancer Society. © 2015 American Cancer Society.

Sponge divers of the Aegean and medical consequences of risky compressed-air dive profiles.

Historically, Turkey once had a substantial number of professional sponge divers, a population known for a relatively high incidence of diving-related conditions such as decompression sickness (DCS) and dysbaric osteonecrosis (DON). Sponge diving ended in the mid-1980s when nearly all of the sponges in the Aegean and Mediterranean Seas contracted a bacterial disease and the occupation became unprofitable. We reviewed the records of Turkish sponge divers for information on their level of knowledge, diving equipment, dive profiles, and occupational health problems. Information was collected by: 1) interviewing former sponge divers near Bodrum, where most of them had settled; 2) reviewing the relevant literature; and 3) examining the medical records of sponge divers who underwent recompression treatment. These divers used three types of surface-supplied equipment, including hard helmets, Fernez apparatus, and hookahs; the latter were preferred because they allowed divers the greatest freedom of movement while harvesting sponges underwater. These divers used profiles that we now know involved a high risk for DCS and DON. We were able to access the records of 58 divers who had received recompression treatment. All of the cases involved severe DCS and delays from dive to recompression that averaged 72 h. Complete resolution of symptoms occurred in only 11 cases (19%). Thus, we were able to document the several factors that contributed to the risks in this occupational group, including unsafe dive profiles, resistance to seeking treatment, long delays before recompression, and the fact that recompression treatment used air rather than oxygen.

Wright, Franklin D; Golden, Gregory S

2010-09-10

Photography often represents the best method to collect and preserve evidence in forensic cases. This is especially true in forensic odontology with cases involving dental identification, human abuse and, perhaps most significantly, bitemark cases. Basic visible light photography is adequate in most dental identification cases; however, full spectrum digital photography is best utilized to collect all available evidence in cases of human abuse and bitemarks. This paper will discuss the types of photographic evidence that should be collected with various forensic odontological cases and the specific techniques utilized in full spectrum forensic digital photography. The use of full spectrum photography captures the forensic injuries using special techniques recording the injuries in each of the four resultant events that occur when light strikes skin.

The authors report their experience with temporomandibular joint (TMJ) traumas involving breakage of the roof of the glenoid cavity, an infrequent event that occurs in those cases in which, as a result of the condylar neck not fracturing, the traumatic energy is transmitted to the middle skull base. As the literature contains no valid series for establishing standardized protocols for the treatment of these fractures, we propose our own orthopedic-functional approach. The patient observed by us had suffered a cranio-facial trauma and presented the classical symptoms and signs of TMJ traumas and complete bilateral Bell paralysis. He was subjected to a CAT scan and then to 2-stage treatment consisting of functional rest with liquid diet followed by physiotherapy. An almost total recovery in TMJ function was observed after 1 month. At 1-year follow-up the facial paralysis had resolved completely. On the basis of our experience, breakages of the glenoid cavity can be compared, in terms of treatment procedure, to intracapsular fractures of the TMJ with surgery confined to cases of ankylosis sequelae. To avoid the onset of ankylosis careful control of clinical, functional and radiological follow-up is required.

Full Text Available Nevus of Ota, a dermal melanocytic nevus, is rare in the Indian subcontinent. It presents as a brown, blue, or gray patch on the face and is within the distribution of the ophthalmic and maxillary branches of the trigeminal nerve. The oral cavity is infrequently involved in nevus of Ota. Only 11 cases have been documented in the English literature. We report a rare case of intraoral nevus of Ota in a 22-year-old male patient. This paper focuses on the differential diagnosis of oral manifestations of nevus of Ota to assist in proper followup to avert malignant transformation.

Full Text Available Posterior reversible encephalopathy syndrome (PRES is a rare entity involving brainstem in very rare reported cases. We describe here the case of a boy who presented to the emergency department for headaches and strabismus. Diagnosis of PRES was retained by magnetic resonance imaging. The causes were blood pressure urgency and renal failure. Location of lesions was very rarely reported in literature and neurological troubles were persistent. Emergency physicians should evocate PRES each time there is a clinical context associated with neurological troubles by a normal brain CT scan. Early diagnosis is very important to treat its causes and improve prognosis.

Adenocarcinoma of the thymus is a very rare malignant tumor. The standard treatment for advanced thymic carcinoma has not yet been established, and the prognosis is poor. We report a case of thymic carcinoma that involving the aortic arch and the innominate vein. A 78-year-old woman was admitted to our hospital complaining of hoarseness in April 2007. The computed tomography (CT) scan showed an anterior mediastinal tumor contiguous to the aortic arch and the innominate vein with swelling lymphnodes. Microspcopic examinations of specimens obtained by CT-guided needle biopsy revealed poorly differenciated adenocarcinoma. The carcinoembryonic antigen (CEA) level of serum elevated at 54.9 ng/ml. Thymic carcinoma was diagnosed. The chemoradiotherapy [concurrent, carboplatin (CBDCA) + paclitaxel(TXL)-->vinorelbine (NVB), 60 Gy] was performed, but the effect of the therapy was limited. The resection of the tumor with a part of aortic arch and other peripheral tissues was performed in Augast 2007. The postoperative course was uneventful and the CEA level of serum lowered to the normal. She was discharged 30 days after surgery.

The Zika virus (ZIKV) is an emerging arthropod-borne virus related to the dengue virus (DENV), and shows a similar clinical profile as other arboviral diseases, such as dengue and chikungunya virus (CHIKV). Historically, ZIKV has been associated with sporadic cases of human infection, but is now responsible for outbreaks worldwide. In Brazil, cases have been reported since 2015, with some cases causing severe disease. To identify clinical symptoms of Zika in patients in Dengue suspected patients. Description of a series of cases, wherein we analyzed 100 clinical samples collected from patients who exhibited acute febrile disease for ≤5days, from January to February 2016. In this study, we report 13 cases of ZIKV infection in adults presenting dengue-like symptoms in a DENV endemic area. All patients presented with fever, with myalgia being the second most frequently observed symptom. Two patients had rashes, but none of them had conjunctivitis. Other less frequent manifestations included headache, arthralgia, diarrhea, and nausea. The co-circulation of ZIKV and DENV is a serious public health concern, since it represents both a clinical and diagnostic challenge in endemic areas, as well as in the field of travel medicine.

Nephroblastoma and neuroblastoma belong to the most common abdominal malignancies in childhood. Similarities in the initial presentation may provide difficulties in distinguishing between these two entities, especially if unusual variations to prevalent patterns of disease manifestation occur. Because of the risk of tumor rupture, European protocols do not require biopsy for diagnosis, which leads to misdiagnosis in some cases. We report on a 4½-year-old girl with a renal tumor displaying radiological and laboratory characteristics supporting the diagnosis of nephroblastoma. Imaging studies showed tumor extension into the inferior vena cava and bilateral lung metastases while urine catecholamines and MIBG-scintigraphy were negative. Preoperative chemotherapy with vincristine, actinomycine D and adriamycin according to the SIOP2001/GPOH protocol for the treatment of nephroblastoma was initiated and followed by surgical tumor resection. Histopathology revealed an undifferentiated tumor with expression of neuronal markers, suggestive of neuroblastoma. MYCN amplification could not be detected. DNA-microarray analysis was performed using Affymetrix genechip human genome U133 plus 2.0 and artificial neural network analysis. Results were confirmed by multiplex RT-PCR. Principal component analysis using 84 genes showed that the patient sample was clearly clustering with neuroblastoma tumors. This was confirmed by hierarchical clustering of the multiplex RT-PCR data. The patient underwent treatment for high-risk neuroblastoma comprising chemotherapy including cisplatin, etoposide, vindesine, dacarbacine, ifosfamide, vincristine, adriamycine and autologous stem cell transplantation followed by maintenance therapy with 13-cis retinoic acid (GPOH NB2004 High Risk Trial Protocol) and is in complete long-term remission. The use of gene expression profiling in an individual patient strongly contributed to clarification in a diagnostic dilemma which finally led to a change of

Amyloidosis in the parotid gland is rare and is usually associated with systemic amyloidosis. Localized amyloidosis in the parotid gland is extremely rare. We present a case of localized light chain amyloidosis of the parotid gland without systemic involvement. A 70-year-old woman presented with an asymptomatic swelling of the right parotid region. The findings of a physical examination, hematologic and biochemical investigations, imaging, and cytology were inconclusive. The patient underwent an extracapsular dissection of the right parotid gland. Histologic analysis showed that the tissue of the right parotid gland mostly consisted of amyloid deposition. The amyloid stained with antibodies to lambda light chains. Additional investigations showed no systemic involvement. The patient is asymptomatic 5 months after surgery. Clinicians should be aware of the possibility of localized amyloid light chain amyloidosis in the parotid gland, especially if magnetic resonance imaging, computed tomography imaging, and ultrasound findings are inconclusive, and they should recognize, evaluate, and treat it accordingly.

To determine the results of "biologic fixation" with a minimally invasive plating technique using a newly designed low profile "Scallop" plate in the treatment of pilon fractures. Retrospective case series. A tertiary referral center. Seventeen patients were treated between 1999 and 2001 for a tibial plafond fracture at the Hospital for Special Surgery with a newly designed low-profile plate. Eleven of the fractures (65%) were high-energy injuries. Two fractures were open. Staged surgical treatment with open reduction and fixation of the fibular fracture and application of an external fixator was performed in 12 cases. As soon as the soft tissues and swelling allowed, i.e. skin wrinkling, the articular surface was reconstructed and simply reduced, if necessary through an small incision, and the articular block was fixed to the diaphysis using a medially placed, percutaneously introduced flat scallop plate. In the remaining five cases the operation was performed in one session. Time to healing and complications including delayed union, non-union, instrument failure, loss of fixation, infection, quality of reduction and number of reoperations were evaluated. Quality of results and outcome were graded using the ankle-hindfoot-scale and a modified rating system. All patients went on to bony union at an average time of 14 weeks. There were no plate failures or loss of fixation/reduction. Two superficial wound-healing problems resolved with local wound care. At an average follow up of 17 months (range 6-29 months) eight patients (47%) had an excellent result; seven (41%) had a fair result whereas two (12%) had a poor result. The average ankle-hindfoot-score was 86.1 (range 61-100). Four patients have had the hardware removed and one of them is awaiting an ankle arthrodesis. Based on these initial results, it appears that a minimally invasive surgical technique including new low profile plate can decrease soft tissue problems while leading to fracture healing and

To date, there is no criterion enabling to determine the spontaneous or radio-induced origin of malignant tumour occurring in a previously irradiated patient. Biological studies are rare. The cytogenetic data which could be found in the literature for eleven radio-induced tumours suggest that aneuploidies and polyclonality are frequent events. We studied, by R-Banding cytogenetic technique, five patients with short-term cultures (3 cases), short and long-term cultures (1 case) and xeno-grafting on nude pattern a high rate of balanced translocations, numerous random break points and a polyclonal evolution (10 clones). All other tumours, including the xeno-grafting sarcoma, had a monoclonal profile with complex karyotypes, hypo-diploid formulas and many deletions. These results show that the mechanism of radiation-induced tumours frequently involves chromosomes losses and deletions. The most likely explanation is that these alterations unmask radiation induced recessive mutations of tumour suppressor genes. (authors)

Identification and expression profiling analysis of TCP family genes involved in growth and development in maize.

2017-10-01

The TCP family is a group of plant-specific transcription factors. TCP genes encode proteins harboring bHLH structure, which is implicated in DNA binding and protein-protein interactions and known as the TCP domain. TCP genes play important roles in plant development and have been evolutionarily and functionally elaborated in various plants, however, no overall phylogenetic analysis or expression profiling of TCP genes in Zea mays has been reported. In the present study, a systematic analysis of molecular evolution and functional prediction of TCP family genes in maize ( Z . mays L.) has been conducted. We performed a genome-wide survey of TCP genes in maize, revealing the gene structure, chromosomal location and phylogenetic relationship of family members. Microsynteny between grass species and tissue-specific expression profiles were also investigated. In total, 29 TCP genes were identified in the maize genome, unevenly distributed on the 10 maize chromosomes. Additionally, ZmTCP genes were categorized into nine classes based on phylogeny and purifying selection may largely be responsible for maintaining the functions of maize TCP genes. What's more, microsynteny analysis suggested that TCP genes have been conserved during evolution. Finally, expression analysis revealed that most TCP genes are expressed in the stem and ear, which suggests that ZmTCP genes influence stem and ear growth. This result is consistent with the previous finding that maize TCP genes represses the growth of axillary organs and enables the formation of female inflorescences. Altogether, this study presents a thorough overview of TCP family in maize and provides a new perspective on the evolution of this gene family. The results also indicate that TCP family genes may be involved in development stage in plant growing conditions. Additionally, our results will be useful for further functional analysis of the TCP gene family in maize.

Perinatal asphyxia and medical professional liability: A case series

Full Text Available In the context of medical professional liability, obstetrics is one of the most involved medical specialties because the unfavorable outcome of a pregnancy is difficult to accept for parents, who tend to reduce it to inappropriate care that occurred during pregnancy or birth. 32 cases of perinatal asphyxia were evaluated by the Institute of Forensic Medicine in Brescia during the period between 1999 and 2014 (13 in Civil Court and 19 in Penal Court. 9 out of the 32 pregnancies were twins, so the considerations were carried out on a total of 41 fetuses/newborns. Profiles of inadequacy were identified in 66% of cases (85% of the cases evaluated in Civil Court; 53% of the cases evaluated in Penal Court. The existence of a causal relationship between the medical conduct and the onset of asphyxia was recognized in 79% of civil cases and in 38% of penal cases. There is a “greater rigor” in the verification of causal relationship and malpractice profiles in penal cases compared to civil ones: this is in harmony with the most recent Italian Court decisions, characterized by compelling suspect’s protection in the presence of a reasonable doubt in criminal matters and by victim’s protection in civil ones.

This study aimed to clarify whether work-related adverse events in cases involving compensation for mental disorders and suicide differ by sex and industry using a database containing all relevant cases reported from 2010 to 2014 in Japan. A total of 1362 eligible cases involving compensation for mental disorders (422 females and 940 males) were analyzed. Among males, 55.7% of cases were attributed to "long working hours." In both sexes, the frequencies of cases attributed to "long working hours" and other events differed significantly by industry. Among cases involving compensation for suicide, 71.4% were attributed to "long working hours." The frequency distribution of work-related adverse events differed significantly by sex and industry. These differences should be taken into consideration in the development of industry-specific preventive measures for occupational mental disorders.

Progression to severe organ involvement due to dengue infection has been associated with severe dengue disease, intensive care treatment, and mortality. However, there is a lack of understanding of the impact of pre-existing comorbidities and other risk factors of severe organ involvement among dengue adults. The aim of this retrospective case-control study is to characterize and identify risk factors that predispose dengue adults at risk of progression with severe organ involvement. This study involved 174 dengue patients who had progressed with severe organ involvement and 865 dengue patients without severe organ involvement, matched by the year of presentation of the cases, who were admitted to Tan Tock Seng Hospital between year 2005 and 2008. Age group of 60 years or older, diabetes, cardiac disorders, asthma, and having two or more pre-existing comorbidities were independent risk factors of severe organ involvement. Abdominal pain, clinical fluid accumulation, and hematocrit rise and rapid platelet count drop at presentation were significantly associated with severe organ involvement. These risk factors, when validated in a larger study, will be useful for triage by clinicians for prompt monitoring and clinical management at first presentation, to minimize the risk of severe organ involvement and hence, disease severity.

Ovarian carcinosarcomas (OCS), also known as malignant mixed mesodermal/Müllerian tumors, are rare neoplasms (1%-4% of all malignant ovarian tumors) composed of high-grade malignant epithelial and mesenchymal elements. OCS occurs in older women. It is associated with a poor outcome and is usually not involved in inherited cancer syndromes. We present 2 cases of OCS; one arising in a patient with a pathogenetic BRCA1 mutation and the other in a woman affected by Lynch Syndrome (LS) carrying a MSH6 germline mutation. To the best of our knowledge, this is the first time that this second type of case has been reported. In this study, we investigated somatic impairment of the wild-type BRCA1 and MSH6 alleles in the OCS of these 2 patients. We also explored in both OCS, the occurrence of TP53 loss of function, which is a genetic alteration known to occur in BRCA-linked ovarian tumorigenesis but not in LS tumors. Moreover, we also provide further data about the histogenesis of OCS.

10 years of 1:1 taping in Belgium - A selection of murder cases involving fibre examination.

De Wael, K; Lepot, L; Lunstroot, K; Gason, F

2016-01-01

Since 2002, the 1:1 tape lifting technique on murder victims has been introduced in Belgium. Thirty-six murder cases for which a fibre examination was carried out in our laboratory between 2002 and 2012 are reviewed. These cases all involved the collection of microtraces on 39 victims using a 1:1 taping or similar technique, called semi 1:1 taping. The degree of "positive outcomes" for investigative and comparative fibre cases is high. Especially in cases where the modus operandi of suspects had to be verified, the examination of the 1:1 tape lifting led to very useful fibre results. The findings from some of these fibre cases are used to illustrate the advantages, drawbacks and points of interest of the two collection techniques. These are also compared with the zonal taping technique, another microtrace collection technique applied on victims at the crime scene. Copyright © 2015 The Chartered Society of Forensic Sciences.

Malignant Pleural Mesothelioma with Marked Lymphatic Involvement: A Report of Two Autopsy Cases

Directory of Open Access Journals (Sweden)

Reiko Ideguchi

2017-01-01

Full Text Available We herein report two cases of malignant pleural mesothelioma with marked lymphangiosis. The patients included a 68-year-old man and a 67-year-old man who both had a history of exposure to asbestos. Computed tomography (CT on admission showed pleural effusion with pleural thickening. In both cases, a histopathological examination of the pleura confirmed the diagnosis of epithelioid malignant mesothelioma. They received chemotherapy, but the treatment was only palliative. The chest CT assessments during admission revealed marked pleural effusion and mediastinal lymphadenopathy. CT also showed a consolidative mass with bronchovascular bundle and septal thickening in the lungs suggesting pulmonary parenchymal involvement and the lymphangitic spread of the tumor. These CT findings mimicked lung cancer with pleuritis and lymphangitic carcinomatosis. Autopsy was performed in both cases. Macroscopically, the tumor cells infiltrated the lung with the marked lymphatic spread of the tumor. Microscopy also revealed that the tumor had invaded the pulmonary parenchyma with the marked lymphatic spread of the tumor. Although this growth pattern is unusual, malignant pleural mesothelioma should be considered as the differential diagnosis, especially in patients with pleural lesions.

Full Text Available Since nasal NK/T cell lymphoma and NK/T cell lymphoma nasal type are rare diseases, gastric involvement has seldom been seen. We report a unique case of a patient with a primary NK/T cell lymphoma nasal type of the stomach with skin involvement. The patient had no history of malignant diseases and was diagnosed with hematemesis and intense bleeding from his gastric primary site. Shortly after this event, exanthemic skin lesions appeared with concordant histology to the primary site. Despite chemotherapy, the patient died one month after the first symptomatic appearance of disease.

Full Text Available Background: Patients who undergo emergency colorectal cancer surgery has poor outcome compared to elective surgery, both in terms of morbidity and mortality. Approximately 15 to 30% of colorectal cancers present as an emergency, most often as obstruction or perforation. Objective: To compare surgical outcome and clinical profiles of emergency and elective cases for colorectal cancer. Methods: Retrospective analysis of 34 cases who underwent surgery for colorectal cancer between December 2011 to January 2013was carried out and their surgical outcomes, clinical presentation, demographic profile were analyzed. Results: The total numbers of patients included in this study were 34. Out of which 52.94 %( n=18 were emergency cases and 47.05 %( n=16 were elective. Male female ratio was 3:1 in emergency cases and 2.6:1 in elective cases. Per rectal bleeding (56% and altered bowel habit (31.25% was predominant clinical presentation in elective cases whereas intestinal obstruction (55.55% and peritonitis (22.22% were predominant clinical presentation in emergency cases. In emergency cases most of the tumors were located in left side (77.77% and in elective cases rectum was common site (37.5%. Left hemicolectomy was the commonest surgery performed (72.22% in emergency set up. In elective cases, right hemicolectomy, left hemicolectomy, APR and LAR was done in 31.25%, 31.25%, 25% and 25% cases respectively. In the emergency group 11.11% (n=2 developed enterocutaneous fistula and early mortality within 30 days was observed in 5% (n=1 of emergency cases only. Conclusion: In emergency conditions, colorectal cancer presented with intestinal obstruction where as elective cases presented with per rectal bleeding and altered bowel habits. Compared with the elective patients, the emergency patients had higher rate of morbidity and mortality. Because of higher incidence of colorectal cancer in our institution, in all emergency cases who presents with features of

Posttransplant lymphoproliferative disorder (PTLD) is a well-recognized complication of solid organ transplantation and commonly affects upper airway lymphoid tissue. Tracheal and laryngeal involvement in patients with PTLD, however, is rare. We present one such case. We report the case of a patient with recurrent PTLD involving the larynx and trachea and describe the presentation, evaluation, management, and outcome. An 11-year-old boy who underwent bilateral nephrectomy and renal transplantation as an infant was admitted to the hospital with chronic cough, fever, stridor, and dyspnea. His post-transplantation course was complicated by PTLD in cervical lymph nodes at 9 years of age that was successfully treated with chemotherapy. A computed tomographic scan during his present admission revealed supraglottic swelling, a distal tracheal mass, and paratracheal lymph node enlargement. The patient underwent laryngoscopy and bronchoscopy with biopsy specimens taken from the right laryngeal ventricle and distal trachea. Pathologic examination yielded a diagnosis of Epstein-Barr virus-positive PTLD. The patient was treated with chemotherapy, which resulted in resolution of the airway lesions, as seen on repeat bronchoscopy. This is the first report, to our knowledge, of recurrent PTLD involving simultaneous lesions in the larynx and the trachea. PTLD in the head and neck can present as lymphoid hypertrophy, airway obstruction, stridor, or cough. A high degree of clinical suspicion is essential for prompt diagnosis of this life-threatening complication.

To describe MRI findings of multiple sclerosis involving the brainstem. Among 35 cases of clinically definite multiple sclerosis, the authors retrospectively analysed 20 in which the brainstem was involved. MR images were analysed with regard to involvement sites in the brainstem or other locations, signal intensity, multiplicity, shape, enhancement pattern, and contiguity of brainstem lesions with cisternal or ventricular CSF space. The brainstem was the only site of involvement in five cases (25%), while simultaneous involvement of the brainstem and other sites was observed in 15 cases (75%). No case involved only the midbrain or medulla oblongata, and simultaneous involvement of the midbrain, pons and medulla oblongata was noted in 12 cases (60%). The most frequently involved region of the brainstem was the medulla oblongata (n=13; 90%), followed by the pons (n=17; 85%) and the midbrain (n=16; 80%). Compared with normal white matter, brainstem lesions showed low signal intensity on T1 weighted images, and high signal intensity on T2 weighted, proton density weighted, and FLAIR images. In 17 cases (85%), multiple intensity was observed, and the shape of lesions varied: oval, round, elliptical, patchy, crescentic, confluent or amorphous were seen on axial MR images, and in 14 cases (82%), coronal or sagittal scanning showed that lesions were long and tubular. Contiguity between brainstem lesions and cisternal or ventricular CSF space was seen in all cases (100%) involving midbrain (16/16) and medulla oblongata (18/18) and in 15 of 17 (88%) involving the pons. Contrast enhancement was apparent in 7 of 12 cases (58%). In the brainstem, MRI demonstrated partial or total contiguity between lesions and cisternal or ventricular CSF space, and coronal or sagittal images showed that lesions were long and tubuler

[The profile of neonaticide mothers in legal expertise].

Vellut, N; Simmat-Durand, L; Tursz, A

2013-10-01

Neonaticide is the term used to refer to the killing of newborn infants within the first 24 hours of life. A recent study conducted by Inserm Unit 750 found a frequency of 2.1 cases of neonaticide for 100,000 births in France. The persistence of these crimes raises serious issues, and scientists have attempted to explain this by the profile of neonaticidal mothers: young, or even teenage, single, primiparous, and socially deprived. The present study sought to question this profile, and to suggest a new profile for neonaticidal mothers. This retrospective study over the years 1996-2000 comprised 32 cases of neonaticide perpetrated in three French regions. Seventeen solved cases of these 32 cases generated 54 documents by expert consultants, mainly psychiatric and psychological expertise, studied and analysed here using Modalisa software for quantitative analyses and Nvivo software for qualitative data. No single socio-demographic profile was observed. The mothers were in contrasting situations at the time of the event. There were few psychotic profiles. The other psychopathological disturbances detected were very often related to the event. The most surprising feature in the expert reports describing the neonaticidal mothers was the existence of what we have termed "descriptive absent-factors". These mothers had not experienced major trauma in childhood such as the death of persons close or foster care. They were not living in an environment of family violence. They did not exhibit addictive or self-harm behaviour. Their parents before them had similar profiles, except three cases of alcoholism. Their parentage, and that of the infants, was not an issue. The most widely described personality features were immaturity, dependency on others, withdrawal, inhibition, emptiness, lack of affectivity, non-expressiveness, and devaluation of self-image. The very impoverished relational environment of these mothers also appears in the expertise data. Their affective and

Numerous xenobiotics have been shown to be harmful for the kidney. Thus, to improve our knowledge of the cellular processing of these nephrotoxic compounds, we evaluated, by real-time PCR, the mRNA expression level of 377 genes encoding xenobiotic-metabolizing enzymes (XMEs), transporters, as well as nuclear receptors and transcription factors that coordinate their expression in eight normal human renal cortical tissues. Additionally, since several renal in vitro models are commonly used in pharmacological and toxicological studies, we investigated their metabolic capacities and compared them with those of renal tissues. The same set of genes was thus investigated in HEK293 and HK2 immortalized cell lines in commercial primary cultures of epithelial renal cells and in proximal tubular cell primary cultures. Altogether, our data offers a comprehensive description of kidney ability to process xenobiotics. Moreover, by hierarchical clustering, we observed large variations in gene expression profiles between renal cell lines and renal tissues. Primary cultures of proximal tubular epithelial cells exhibited the highest similarities with renal tissue in terms of transcript profiling. Moreover, compared to other renal cell models, Tacrolimus dose dependent toxic effects were lower in proximal tubular cell primary cultures that display the highest metabolism and disposition capacity. Therefore, primary cultures appear to be the most relevant in vitro model for investigating the metabolism and bioactivation of nephrotoxic compounds and for toxicological and pharmacological studies. - Highlights: • Renal proximal tubular (PT) cells are highly sensitive to xenobiotics. • Expression of genes involved in xenobiotic disposition was measured. • PT cells exhibited the highest similarities with renal tissue.

Since the recent introduction of the Case/Care Manager's professional figure, it is quite difficult to identify properly his/her own particular features, which could be mainly be found revising mainly in American studies. Therefore, the present study intended to identify the Case/Care Manager's skills and professional profile in an Intensive Care Unit experience, taking into consideration the staff's activities, perception and expectations towards the Case/Care Manager. In particular, it has been compared the experience of an Intensive Care Units where the Case/Care Manager's profile is operational to a different Unit where a Case/Care Manager is not yet in force. a Levati's model was used to map the Case/Care Manager's skills, involving each unit whole working staff, executives and caregivers through semi-structured interviews. It has been taken into consideration the Anaesthesia Unit and Emergency Unit of Cesena's healthcare organisation (AUSL of Romagna) and a Cardiology Intensive Care Unit of Piacenza's healthcare organisation, where the Case/Care Manager's profile has not been experimented yet. Firstly, it a data collection in each healthcare organization has been organised. Subsequently, semi-structured interviews to doctors, unit nurses, caregivers, nurses' coordinators and medical staff have been used to compare each healthcare system. The interviewees' described their expectations in relation to the Case/Care Manager working in a critical area. Then, every data collected during interviews has been organised to map a Case/Care Manager's essential professional profile to work in a critical area together with medical staff. Piacenza's O.U. critical area experience reported a major demand for patients' and patient's families' assistance. On the other hand, the very same aspects seem to have been better achieved in Cesena's O.U., where a Case/Care Manager's recent introduction has actually helped to overcome the void in organising systems. a Case/Care Manager

Two incidents involving internal exposure by inhalation of transuranic compounds are presented herein. The results of the measurements of urinary and faecal excretions of the two individuals involved do not concur with the values predicted by the ICRP models that should be applied by default, according to the circumstances of the incidents and the chemical form of the products involved: oxide in the first case and nitrate in the second. These cases are remarkable in the similarity of their biokinetic behaviour even though they occurred in different situations and involved different chemical compounds. Both situations provide an illustration of the management of internal contamination events. The precautions to be taken and the questions that the physician should ask himself in the estimation of the internal dose are listed as follows: What type of examinations should be prescribed and at what frequency? What analysis results should be used in assessing the dose? How can the effect of the Ca-DTPA treatment be assessed? How long is it necessary to perform radio toxicological exams before assessing the dose? What should be done if the ICRP model corresponding to the initial circumstances does not fit the measurement data? Finally, our selected hypotheses, used to explain specific biokinetic behaviour and to estimate its intake in both cases, are detailed. These incidental contaminations suggest that further studies should be carried out to develop a new model for inhalation of transuranic compounds that would follow neither the S nor the M absorption type of the respiratory tract model of ICRP publication 66.

We report an uncommon 22-year-old male Pulmonary Langerhans Cell Histiocytosis (PLCH) case which co-existed with pulmonary tuberculosis (TB). Unlike the common PLCH cases, this PLCH case has cervical lymph node involvement and right pneumothorax. The diagnosis was established by the imaging of lung and the biopsies of the lung and left neck lymph node. Imaging of the chest showed characteristic small nodules and thin-walled cysts and right pneumothorax. The LCH cells in the lung and left neck lymph node were characterized by large convoluted nuclei with cerebriform indentations of the nuclear envelope and longitudinal grooves. The nuclei contained small eosinophilic nucleoli and moderate amount cytoplasm. Immunohistochemically, the histiocytoid cells were positive for Langerin, CD1a and S-100. Acid-fast bacilli were found in sputum and lung biopsy tissue. To the best of our knowledge, this is the first case of PLCH with cervical lymph node involvement, and coexisted with pulmonary tuberculosis, right pneumothorax. A contribution of this case and review three of the five cases of PLCH with extrapulmonary involvement to lymph nodes resolved spontaneously after smoking cessation constitute a novel addition that it is inappropriate to regard pulmonary/nodal LCH as multi-organ or disseminated disease, and the treatment methods are the same whether the PLCH patient with lymph node involvement or not.

Ameloblastic fibroma is a rare, slow-growing benign mixed odontogenic tumor. It constitutes 2% of odontogenic tumors and is reported to occur at an age ranging from 6 months to 42 years. The youngest being a 7-week-old infant. We report a case of peripheral ameloblastic fibroma in a 2-week-old infant. The lesion presented since birth. It involved the maxilla with an extraosseous component involving the gingiva. A more or less conservative surgical approach of enucleation and curettage of the lesion was done under general anesthesia, trying to conserve the adjacent tooth buds. Only a few cases of congenital peripheral ameloblastic fibroma have been reported so far.

In this study, we examined the internal consistency and structural validity of Cross Racial Identity Scale (CRIS) scores in a sample of 477 African American adolescents who had been arrested in a city in the mid-Atlantic. Using cluster analysis, we also identified profiles of CRIS scores and compared adolescents with different profiles on Major Depressive Episode, Manic Episode, Generalized Anxiety Disorder, and Obsessive-Compulsive Disorder scores. Results indicated that CRIS subscale scores were reliable, and the 6-factor structure of the CRIS was supported. Five nigrescence profiles were identified: Miseducation-Pro-Black, Conflicted-Self-Hatred, Multiculturalist, Low Race Salience, and Conflicted-Anti-White. Individuals with Conflicted-Self-Hatred profiles reported significantly and meaningfully higher scores on the 4 syndromes than did their peers, and individuals with the Multiculturalist and Low Race Salience profiles reported the lowest scores. A greater percentage of individuals with Conflicted racial identity profiles had syndrome scores in the clinically significant range. The results of this study demonstrate that some of the nigrescence profiles found in college-age students generalize to adolescents. The implications of the findings for theory, research, and practice are discussed. PsycINFO Database Record (c) 2014 APA, all rights reserved.

One of students’ characteristics which play an important role in learning mathematics is logical-mathematical intelligence. This present study aims to identify profile of students’ logical-mathematical intelligence in general and specifically in each indicator. It is also analyzed and described based on students’ sex. This research used qualitative method with case study strategy. The subjects involve 29 students of 9th grade that were selected by purposive sampling. Data in this research involve students’ logical-mathematical intelligence result and interview. The results show that students’ logical-mathematical intelligence was identified in the moderate level with the average score is 11.17 and 51.7% students in the range of the level. In addition, the level of both male and female students are also mostly in the moderate level. On the other hand, both male and female students’ logical-mathematical intelligence is strongly influenced by the indicator of ability to classify and understand patterns and relationships. Furthermore, the ability of comparison is the weakest indicator. It seems that students’ logical-mathematical intelligence is still not optimal because more than 50% students are identified in moderate and low level. Therefore, teachers need to design a lesson that can improve students’ logical-mathematical intelligence level, both in general and on each indicator.

Full Text Available The EU Flood Risk Management Directive 2007/60/EC aims at an active involvement of interested parties in the setting up of flood risk management plans and thus calls for more governance-related decision-making. This requirement has two perspectives. On the one hand, there is (1 the question of how decision-makers can improve the quality of their governance process. On the other hand, there is (2 the question of how the public shall be appropriately informed and involved. These questions were the centre of the ERA-Net CRUE-funded project IMRA (integrative flood risk governance approach for improvement of risk awareness that aimed at an optimisation of the flood risk management process by increasing procedural efficiency with an explicit involvement strategy. To reach this goal, the IMRA project partners developed two new approaches that were implemented in three case study areas for the first time in flood risk management: 1. risk governance assessment tool: An indicator-based benchmarking and monitoring tool was used to evaluate the performance of a flood risk management system in regard to ideal risk governance principles; 2. social milieu approach: The concept of social milieus was used to gain a picture of the people living in the case study regions to learn more about their lifestyles, attitudes and values and to use this knowledge to plan custom-made information and participation activities for the broad public. This paper presents basic elements and the application of two innovative approaches as a part of an "involvement strategy" that aims at the active involvement of all interested parties (stakeholders for assessing, reviewing and updating flood risk management plans, as formulated in the EU Flood Risk Management Directive 2007/60/EC.

By analyzing the clinical data of 1 case of IgG4-related lung disease(IgG4-RLD) and the review of literature, the author investigated the clinical characteristics of IgG4-RLD. IgG4-RLD is a rare disease characterized by significant elevation of serum IgG4 and infiltration of a large number of IgG4+ plasma cells. The clinical manifestations of the disease were nonspecific, and the imaging features were mixed with several types. The disease can only be involved in the lung, but also multiple organ involvement. Solely lung-involved IgG4-RD is not only extremely rare but also easily misdiagnosed as tuberculosis, lung cancer, lymphoma and other common pulmonary diseases. Histopathological examination is the key to the diagnosis of the disease. Corticosteroids are the first choice of treatment, and the overall prognosis is good.

Full Text Available Objective: Elevated serum ferritin has been linked to type 2 diabetes (T2D and adverse health outcomes in subjects with the Metabolic Syndrome (MetS. As the mechanisms underlying the negative impact of excess iron have so far remained elusive, we aimed to identify potential links between iron homeostasis and metabolic pathways. Methods: In a cross-sectional study, data were obtained from 163 patients, allocated to one of three groups: (1 lean, healthy controls (n = 53, (2 MetS without hyperferritinemia (n = 54 and (3 MetS with hyperferritinemia (n = 56. An additional phlebotomy study included 29 patients with biopsy-proven iron overload before and after iron removal. A detailed clinical and biochemical characterization was obtained and metabolomic profiling was performed via a targeted metabolomics approach. Results: Subjects with MetS and elevated ferritin had higher fasting glucose (p < 0.001, HbA1c (p = 0.035 and 1 h glucose in oral glucose tolerance test (p = 0.002 compared to MetS subjects without iron overload, whereas other clinical and biochemical features of the MetS were not different. The metabolomic study revealed significant differences between MetS with high and low ferritin in the serum concentrations of sarcosine, citrulline and particularly long-chain phosphatidylcholines. Methionine, glutamate, and long-chain phosphatidylcholines were significantly different before and after phlebotomy (p < 0.05 for all metabolites. Conclusions: Our data suggest that high serum ferritin concentrations are linked to impaired glucose homeostasis in subjects with the MetS. Iron excess is associated to distinct changes in the serum concentrations of phosphatidylcholine subsets. A pathway involving sarcosine and citrulline also may be involved in iron-induced impairment of glucose metabolism.

2012-10-01

Full Text Available Abstract Background The human inferior frontal junction area (IFJ is critically involved in three main component processes of cognitive control (working memory, task switching and inhibitory control. As it overlaps with several areas in established anatomical labeling schemes, it is considered to be underreported as a functionally distinct location in the neuroimaging literature. While recent studies explicitly focused on the IFJ's anatomical organization and functional role as a single brain area, it is usually not explicitly denominated in studies on cognitive networks. However based on few analyses in small datasets constrained by specific a priori assumptions on its functional specialization, the IFJ has been postulated to be part of a cognitive control network. Goal of this meta-analysis was to establish the IFJ’s connectivity profile on a high formal level of evidence by aggregating published implicit knowledge about its co-activations. We applied meta-analytical connectivity modeling (MACM based on the activation likelihood estimation (ALE method without specific assumptions regarding functional specialization on 180 (reporting left IFJ activity and 131 (right IFJ published functional neuroimaging experiments derived from the BrainMap database. This method is based on coordinates in stereotaxic space, not on anatomical descriptors. Results The IFJ is significantly co-activated with areas in the dorsolateral and ventrolateral prefrontal cortex, anterior insula, medial frontal gyrus / pre-SMA, posterior parietal cortex, occipitotemporal junction / cerebellum, thalamus and putamen as well as language and motor areas. Results are corroborated by an independent resting-state fMRI analysis. Conclusions These results support the assumption that the IFJ is part of a previously described cognitive control network. They also highlight the involvement of subcortical structures in this system. A direct line is drawn from works on the functional

To describe the epidemiological profile of tuberculosis cases reported among health care workers in the Tuberculosis Control Program of the Cassiano Antonio of Moraes University Hospital in Vitoria, Brazil. A retrospective descriptive study of secondary data was conducted between 2002 and 2006. Twenty-five cases of health care workers with tuberculosis were reported: 8 in nursing technicians (32%); 4 in doctors (16%); 3 in nurses (12%); 2 in radiology technicians (8%) and 8 in professionals from other categories (32%). Of those 25 health care workers, 14 (56%) were male and 11 (44%) were female. The incidence of the disease was highest among those from 35 to 39 years of age. The predominant clinical presentation was extrapulmonary (12 cases, 48%), followed by pulmonary (11 cases, 44%) and a combination of the two (2 cases, 8%). Regarding comorbidities, AIDS, alcoholism and smoking, respectively, were present in 33.3% of the study population. Outcomes were as follows: 22 cases of cure (88%); 2 transfers (8%); and 1 death (4%). The proportion of health care workers diagnosed with tuberculosis in the period studied was 2.53%. The results show the need for heath care workers who work in the tuberculosis control program to fill out the field "professional occupation" on the tuberculosis case registry database reporting forms. In addition, this situation draws attention to the need to implement an occupational tuberculosis control program.

Rocky Mountain Spotted Fever (RMSF), caused by Rickettia rickettsii, is a serious tickborne illness that is endemic in the southeastern United States. Although it is most commonly known as a cause of fever and rash, it can have systemic manifestations. The myocardium may rarely be involved, with symptoms that can mimic those of acute coronary syndromes. This report describes a case of serologically proven RMSF causing symptomatic myocarditis, manifested by chest pain, elevated cardiac enzyme levels, and decrease myocardial function. After treatment with antibiotics, the myocarditis resolved. Thus, although unusual, the clinician should be aware of myocardial disease in patients with appropriate exposure histories or other clinical signs of RMSF. Close monitoring and an aggressive approach are essential to reduce mortality rates.

Full Text Available Exergy rate profiles, exergetic efficiency and irreversibility were used to examine the driving forces in multicomponent distillation system with the view to identifying feasible and efficient operating parameters. The mixture used comprised of 5% propane, 15% iso-butane, 25% nbutane, 20% iso-pentane and 35% n-pentane. Operating variables were feed temperature (-30 oC and -80 oC, pressure (800 kPa and 1200 kPa, and reflux-ratio (2 and 6. Stage-by-stage system exergy analysis was estimated. Column profiles of base case -30 oC, -80 oC, -30 oC-reflus ratio 6, -80 oC reflux ratio 6 and base case reflux ratio 6 did not crossed thus are thermodynamically feasible. Base case -30 oC-reflux ratio 2, -80 oC-reflux ratio 2, and base case-reflux ratio 2 were crossed and constricted and are infeasible. Base case results gave efficiency of 81.7% at depropanizer and 65.2% at debutanizer. Base cases sensitivity results with -30 oC, -80 oC and reflux ratio 6, efficiency range 57.40 – 70% and 65.20% - 54.90% for depropanizer and debutanizer respectively. Spitted cases gave 81.7% and 62.20% with more scatter profiles. Splitted feed base case -30 oC design gave the lowest overall system exergy loss rate of 1.12E+6 and efficiency of 95.70%. Design feasible parameters, system efficiency and irreversibility which form basis

Full Text Available Introduction: Our present observational study attempted to evaluate the clinical profiles, diagnosis, treatment and follow-up results of 51 pediatric neurocysticercosis patients over a mean duration of five years (from January 2006 to December 2010. Materials and Methods: Diagnosis was mainly based on clinical features, computed tomography (CT/magnetic resonance imaging scan and exclusion of other causes. Patients with active, transitional cysts and seizure were treated with albendazole for 28 days, steroids and anticonvulsants. Results: A total of 38 patients completed this study. Mean age of the presentation was 8.47 ± 3.19 years 52.6% of the patients were female. Overall patients presented with generalized seizure in 55.3%, focal in 31.6%, headache ± vomiting in 63.2%, focal neurodeficit in 10.5% and combination of symptoms in 60.5% cases. Contrast CT brain showed a solitary lesion in 27 (71.1% and multiple in the rest. At presentation lesions were transitional in 58.2%, inactive in 20% and mixed in 14.6%. After a mean of 2 years, seizure persisted in 9 (23.7% and headache in 8 (21.1% of whom six had normal electroencephalography (EEG while one each showed focal slowing, generalized slowing and epileptiform discharges. During the follow-up, CT scan brain 44.7% lesions calcified, 31.6% disappeared, 10.5% regressed and the rest persisted. Conclusion: Solitary ring enhancing lesions (transitional stage involving the parietal lobe was the commonest CT picture at presentation. Generalized tonic-clonic seizure was the most common type of seizure. Number of lesions, persistence of lesion, number of seizures, EEG abnormality at presentation were not found to be prognostically significant (P > 0.05.

Regression analysis has been performed on a number of measured profiles including temperature and density vs. nominal macroscopic operating parameters for TEXT tokamak (pre-upgrade) ohmic plasmas. The resulting simple empirical model has enabled the authors to quickly approximate profiles of electron temperature and density, ion temperature, and soft x-ray brightness, as well as the scalar quantities: total radiated power, q=1 radius, sawtooth period and amplitude, and energy confinement time as a power law of toroidal field, plasma current, chord average density, and fueling gas atomic weight. The model profiles are only applicable to the plasma interior, i.e. within the limiter radius. In most cases the predicted model profiles are within the experimental error bars of measured profiles and are more accurate at predicting profile variation for small operating parameter changes than the measured profiles

Children with reading disability exhibit varied deficits in reading and cognitive abilities that contribute to their reading comprehension problems. Some children exhibit primary deficits in phonological processing, while others can exhibit deficits in oral language and executive functions that affect comprehension. This behavioral heterogeneity is problematic when missing data prevent the characterization of different reading profiles, which often occurs in retrospective data sharing initiatives without coordinated data collection. Here we show that reading profiles can be reliably identified based on Random Forest classification of incomplete behavioral datasets, after the missForest method is used to multiply impute missing values. Results from simulation analyses showed that reading profiles could be accurately classified across degrees of missingness (e.g., ∼5% classification error for 30% missingness across the sample). The application of missForest to a real multi-site dataset with missingness ( n = 924) showed that reading disability profiles significantly and consistently differed in reading and cognitive abilities for cases with and without missing data. The results of validation analyses indicated that the reading profiles (cases with and without missing data) exhibited significant differences for an independent set of behavioral variables that were not used to classify reading profiles. Together, the results show how multiple imputation can be applied to the classification of cases with missing data and can increase the integrity of results from multi-site open access datasets.

May Stakeholders be Involved in Design Without Informed Consent? The Case of Hidden Design.

Pols, A J K

2017-06-01

Stakeholder involvement in design is desirable from both a practical and an ethical point of view. It is difficult to do well, however, and some problems recur again and again, both of a practical nature, e.g. stakeholders acting strategically rather than openly, and of an ethical nature, e.g. power imbalances unduly affecting the outcome of the process. Hidden Design has been proposed as a method to deal with the practical problems of stakeholder involvement. It aims to do so by taking the observation of stakeholder actions, rather than the outcomes of a deliberative process, as its input. Furthermore, it hides from stakeholders the fact that a design process is taking place so that they will not behave differently than they otherwise would. Both aspects of Hidden Design have raised ethical worries. In this paper I make an ethical analysis of what it means for a design process to leave participants uninformed or deceived rather than acquiring their informed consent beforehand, and to use observation of actions rather than deliberation as input for design, using Hidden Design as a case study. This analysis is based on two sets of normative guidelines: the ethical guidelines for psychological research involving deception or uninformed participants from two professional psychological organisations, and Habermasian norms for a fair and just (deliberative) process. It supports the conclusion that stakeholder involvement in design organised in this way can be ethically acceptable, though under a number of conditions and constraints.

Breast cancer is the most common malignancy among women in the United States with the second highest incidence of cancer-related death following lung cancer. The decision-making process regarding adjuvant therapy is a time intensive dialogue between the patient and her oncologist. There are multiple tools that help individualize the treatment options for a patient. Population-based analysis with Adjuvant! Online and genomic profiling with Oncotype DX are two commonly used tools in patients with early stage, node-negative breast cancer. This case report illustrates a situation in which the population-based prognostic and predictive information differed dramatically from that obtained from genomic profiling and affected the patient's decision. In light of this case, we discuss the benefits and limitations of these tools.

Speeding is one of the most relevant risk behaviors for serious and fatal accidents, particularly among young drivers. This study presents a tailoring strategy for anti-speeding communication. By referring to their motivational dispositions toward speeding derived from motivational models of health behavior, young car drivers were segmented into different risk groups. In order to ensure that risk communication efforts would actually be capable to target these groups, the linkage between the risk profiles and communication preferences were explored. The study was conducted on the basis of survey data of 1168 German car drivers aged between 17 and 24 years. The data reveal four types of risk drivers significantly differing in their motivational profiles. Moreover, the findings show significant differences in communication habits and media use between these risk groups. By linking the risk profiles and communication preferences, implications for tailoring strategies of road safety communication campaigns are derived. Promising segmentation and targeting strategies are discussed also beyond the current case of anti-speeding campaigns. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available Ameloblastic fibroma is a rare, slow-growing benign mixed odontogenic tumor. It constitutes 2% of odontogenic tumors and is reported to occur at an age ranging from 6 months to 42 years. The youngest being a 7-week-old infant. We report a case of peripheral ameloblastic fibroma in a 2-week-old infant. The lesion presented since birth. It involved the maxilla with an extraosseous component involving the gingiva. A more or less conservative surgical approach of enucleation and curettage of the lesion was done under general anesthesia, trying to conserve the adjacent tooth buds. Only a few cases of congenital peripheral ameloblastic fibroma have been reported so far.

Information regarding physiopathology and complications in fatal cases of chikungunya virus (CHIKV) is scarce. The aim of this study was to describe the frequency and severity of renal complications in fatal cases associated with CHIKV infection based on the clinical and histopathological features from post-mortem tissue biopsies. This retrospective study included fatal cases associated with CHIKV infection occurring from September 2014 through October 2015, reported to National System for Public Health Surveillance (SIVIGILA) and laboratory-confirmed by the National Institute of Health of Colombia. Medical records from 13 patients were available. Information was collected on history, physical examination, and haematological, biochemical, radiological, and virologic investigation reports. Diagnosis of CHIKV infection was performed by positive CHIKV-PCR on post-mortem tissue in 10 cases, positive CHIKV-PCR in serum in 6 cases and anti-CHIKV virus IgM in 2 cases. Only 3 cases were children (≤5 years old). Four cases had underlying diseases, mainly systemic arterial hypertension. The median value of creatinine at admission was 2.8 mg/dL (interquartile range 1.52-4.51). During hospitalization, 9 cases required ICU admission, 8 vasopressor support and 6 mechanical ventilation. Kidney histopathological findings were mainly acute interstitial nephritis (11 cases), congestion/oedema glomerular (10 cases) and acute tubular necrosis (5 cases). Renal impairment in fatal cases of CHIKV infection is frequent and related mainly to acute interstitial nephritis. These data demonstrate evidence of acquired kidney injuries during CHIKV infection.

Sarcoidosis is an inflammatory disorder characterized by the presence of non-caseating granulomas in affected organs. The presence of CD4-positive T lymphocytes and macrophages in affected organs suggests an ongoing immune response. Systemic corticosteroids remain the mainstay of treatment, but therapy is often limited by adverse effects. This is the first report of the use of adalimumab (HUMIRA((R)), Abbott Laboratories, North Chicago, IL, USA), an anti-tumor necrosis factor monoclonal antibody, in a patient with systemic sarcoidosis with bone marrow involvement. A 42-year-old African-American man with a medical history significant for hypertension and diabetes mellitus presented with anemia and thrombocytopenia of two months duration. The patient underwent physical examination, bone marrow aspiration and biopsy, chest X-ray, acid-fast bacilli stain, computed tomography with contrast, and additional laboratory tests. He was diagnosed with systemic sarcoidosis with splenomegaly and bone marrow involvement. Drug therapy included prednisone, which had to be discontinued owing to adverse effects, and adalimumab. This is the first report describing the use of adalimumab in a patient with systemic sarcoidosis with bone marrow involvement. Tumor necrosis factor antagonism with adalimumab was efficacious and well-tolerated in this patient and may be considered as a treatment option for similar cases.

Multiple sclerosis (MS) is a chronic disorder that affects the central nervous system myelin. However, a few radiological cases have documented an involvement of peripheral cranial nerves, within the subarachnoid space, in MS patients. We report the case of a 36-year-old female with a history of relapsing-remitting (RR) MS who consulted for a subacute complete paralysis of the right III nerve. Magnetic resonance imaging (MRI) examination showed enhancement and thickening of the cisternal right III nerve, in continuity with a linear, mesencephalic, acute demyelinating lesion. Radiological involvement of the cisternal part of III nerve has been reported only once in MS patients. Radiological involvement of the cisternal part of V nerve occurs more frequently, in almost 3% of MS patients. In both situations, the presence of a central demyelinating lesion, in continuity with the enhancement of the peripheral nerve, suggests that peripheral nerve damage is a secondary process, rather than a primary target of demyelination.

Modifying locally the safety profile to improve the confinement of magnetic field lines in tokamak plasmas

International Nuclear Information System (INIS)

Constantinescu, D.; Firpo, M.-C.

2012-01-01

Using Hamiltonian models for the magnetic field lines, we propose a methodology to improve their confinement through the creation of transport barriers. A local modification of the safety profile creating a low-shear zone is shown to be sufficient to locally enhance drastically the regularity of the magnetic field lines without requesting a reversed shear. The optimal benefits of low-shear are obtained when the value q 0 of the safety profile in the low-shear zone is sufficiently far from the main resonance values m/n with low m and n, in the case of large enough values of those (m, n) mode amplitudes. A practical implementation in tokamak plasmas should involve electron cyclotron current drive to locally modify the magnetic shear. (paper)

Uterine cervix carcinomas spread by direct local extension, lymphatic permeation and hematogenous dissemination. Their metastatic foci are closely related to iliopsoas compartment anatomically no matter what the pattern of spread is. Therefore, iliopsoas involvement in uterine cervix cancer may occur frequently. The authors reviewed pelvis CT of 218 cervix cancer patients for recent one year from March 1986 to February 1987 at Seoul National University Hospital. Among them, 10 cases showed iliopsoas involvement. Pattern of iliopsoas involvement was classified into four types: infiltrative type (three cases), localized mass type (three cases), mass with bone destruction type (two cases), paraaortic lymphadenopathy type (two cases). In all cases except 3 cases of infiltrative type, lymphadenopathy or bone metastasis adjacent to iliopsoas lesion was identified. And this finding suggested that the route of iliopsoas involvement in cervix cancer would be secondary infiltration from metastatic focus of adjacent lymph node or bone. Recognition of iliopsoas involvement of cervix caner may prevent misdiagnosis and predict the degree of disease dissemination

Stratigraphic Profiles for Selected Hanford Site Seismometer Stations and Other Locations

Last, George V. [Pacific Northwest National Lab. (PNNL), Richland, WA (United States)

2014-02-01

Stratigraphic profiles were constructed for eight selected Hanford Site seismometer stations, five Hanford Site facility reference locations, and seven regional three-component broadband seismometer stations. These profiles provide interpretations of the subsurface layers to support estimation of ground motions from past earthquakes, and the prediction of ground motions from future earthquakes. In most cases these profiles terminated at the top of the Wanapum Basalt, but at selected sites profiles were extended down to the top of the crystalline basement. The composite one-dimensional stratigraphic profiles were based primarily on previous interpretations from nearby boreholes, and in many cases the nearest deep borehole is located kilometers away.

Full text: The usefulness of film to perform dosimetric measurement is a topic often discussed and not clearly agreed upon. While single point measurement detectors give consistent and reliable results for physically wedged fields they cannot be easily used to measure intensity modulated fields. In this work a method of using film to measure profiles for dynamically wedged (DW) fields is presented. The method of positioning film for the subsequent generation of a conversion function to allow for the variation in films' response with energy is outlined. Furthermore, the profiles determined by film measurement are compared with those measured with single point measurement detector and an array of silicon diodes. Both Leavitt et. al. 8 and Weber et. al. 7 have reported on the successful use of the linear diode array (LDA) in measuring dynamic wedge data. This claim will be investigated. The film used in this work was Kodak X-Omat V. The solid water was RW3 with high water equivalency in the range from 137 CS to 50 MV for photons and electrons. All films were processed in an automatic processor. Both the Wellhoefer and the Scanditronix RFA 300 densitometers were used to take film readings. Wedged field and open field profiles measurements were taken in water using both the Wellhoefer IC-10 chamber, the Scanditronix RFA 300 RK chamber and the Scanditronix LDA . The energy investigated was 6 MV at 1.5, 5.0, 10.0, 15.0 and 20.0 cm for a Varian 2100C machine. More consistent density readings were obtained when films were processed with the edge of the film that was parallel to the beam axis was fed into the processor first; rather than when the beam incident edge was fed into the processor first. Comparing the position of the central axis (CAX) of open films from the geometric method developed in this work to the software determined CAX (as available with the Wellhoefer software), it was found that the difference in CAX positions varied between -0.03 to +0.04 cm at 2.5 cm

Exploring technological limits is a common practice in forensic DNA research. Reliable genetic profiling based on only a few cells isolated from trace material retrieved from a crime scene is nowadays more and more the rule rather than the exception. On many crime scenes, cartridges, bullets, and casings (jointly abbreviated as CBCs) are regularly found, and even after firing, these potentially carry trace amounts of biological material. Since 2003, the Forensic Laboratory for DNA Research is routinely involved in the forensic investigation of CBCs in the Netherlands. Reliable DNA profiles were frequently obtained from CBCs and used to match suspects, victims, or other crime scene-related DNA traces. In this paper, we describe the sensitive method developed by us to extract DNA from CBCs. Using PCR-based genotyping of autosomal short tandem repeats, we were able to obtain reliable and reproducible DNA profiles in 163 out of 616 criminal cases (26.5%) and in 283 out of 4,085 individual CBC items (6.9%) during the period January 2003-December 2009. We discuss practical aspects of the method and the sometimes unexpected effects of using cell lysis buffer on the subsequent investigation of striation patterns on CBCs.

Parrots and cockatoos are highly prized aviary birds and the demands for such species has fuelled their illegal trade and harvest from the wild. Here we report on three forensic case studies involving black-cockatoos (Calyptorhynchus spp.) endemic to Australia. These cases involve suspected poaching and illegal killing of endangered red- and white-tailed black-cockatoos. Through the prior development of 20 polymorphic microsatellite loci and population databases for white- and red-tailed black-cockatoos, the tools are available to conduct high-resolution paternity and individual identity testing. In one case, we matched a red-tailed black-cockatoo nestling to a tree hollow from which it was poached through the use of DNA from eggshell recovered from the nest. For the second case, we utilized our provenance population database (nest sites), and identified the kinship and geographic origin of a white-tailed black-cockatoo, which was illegally harvested from the wild. The third case determined the number individual white-tailed black-cockatoos allegedly shot at a fruit grower's orchard from body part remains. These genetic investigations highlight the significance and statistical confidence of DNA profiling and associated databases for endangered taxa, such as exotic birds. Our cockatoo population databases are the first of their kind in Australia, and demonstrate the efficacy of such approaches to identify such illegal activity. With a robust set of genetic markers and methodologies in place, we aim to broaden our population databases to include other cockatoo species of conservation concern.

MetAssimulo:Simulation of Realistic NMR Metabolic Profiles

Directory of Open Access Journals (Sweden)

De Iorio Maria

2010-10-01

Full Text Available Abstract Background Probing the complex fusion of genetic and environmental interactions, metabolic profiling (or metabolomics/metabonomics, the study of small molecules involved in metabolic reactions, is a rapidly expanding 'omics' field. A major technique for capturing metabolite data is 1H-NMR spectroscopy and this yields highly complex profiles that require sophisticated statistical analysis methods. However, experimental data is difficult to control and expensive to obtain. Thus data simulation is a productive route to aid algorithm development. Results MetAssimulo is a MATLAB-based package that has been developed to simulate 1H-NMR spectra of complex mixtures such as metabolic profiles. Drawing data from a metabolite standard spectral database in conjunction with concentration information input by the user or constructed automatically from the Human Metabolome Database, MetAssimulo is able to create realistic metabolic profiles containing large numbers of metabolites with a range of user-defined properties. Current features include the simulation of two groups ('case' and 'control' specified by means and standard deviations of concentrations for each metabolite. The software enables addition of spectral noise with a realistic autocorrelation structure at user controllable levels. A crucial feature of the algorithm is its ability to simulate both intra- and inter-metabolite correlations, the analysis of which is fundamental to many techniques in the field. Further, MetAssimulo is able to simulate shifts in NMR peak positions that result from matrix effects such as pH differences which are often observed in metabolic NMR spectra and pose serious challenges for statistical algorithms. Conclusions No other software is currently able to simulate NMR metabolic profiles with such complexity and flexibility. This paper describes the algorithm behind MetAssimulo and demonstrates how it can be used to simulate realistic NMR metabolic profiles with

Case report 390: Tuberculous pseudotumor of the proximal end of the right tibia without obvious synovial involvement

Energy Technology Data Exchange (ETDEWEB)

Abdelwahab, I.F.; Present, D.A.; Klein, M.J.

1986-11-01

A case of osseous tuberculosis has been presented in a young black man who was known to be an addict to cocaine. An osteolytic lesion involved the proximal end of the tibia, being eccentric and subarticular in location. The knee joint spaces were intact, suggesting that no obvious involvement of the cartilages was present. Thus, neoplastic lesions such as chondroblastoma and giant cell tumor were considered in the differential diagnosis of the lesion which appeared to be benign radiologically. The lesion proved to be tuberculous in nature, with intact knee joint cartilages. A diagnosis of tuberculous 'pseudotumor' might be used aptly. (orig./SHA).

Student involvement as a vehicle for empowerment: a case study of the student platform for engineering education development

KAUST Repository

Delaine, David A.

2010-08-01

This paper examines the mission, structure and outputs of one organisation, the Student Platform for Engineering Education Development (SPEED), as a case study for how student-led organisations can use student involvement to promote and sustain student self-efficacy in an academic field. SPEED attracts young people to engineering through student participation in engineering education (EE). SPEED is a global, non-profit student organisation that functions as an interdisciplinary network to diversify dialogue, stimulate change and impact the development of EE and its effect on society. SPEED is directly attracting young people to engineering in various ways: the organisation of its keynote event, the Global Student Forum; facilitating interactions between globally minded, socially inclined engineers with aspirations to change the world; and through the global dissemination of SPEED\\'s work and practices through broad and relevant channels. Short-term outcomes are highlighted here. This case study can serve as a model for student engagement and involvement in other disciplines. © 2010 SEFI.

Mariel Asbury Marlow

Full Text Available BACKGROUND: Although known to be highly endemic in the Amazon regions of Brazil, the presence of cutaneous leishmaniasis (CL in the subtropical southern part of the country has largely been ignored. This study was conducted to demonstrate CL is emerging in the Brazilian state of Santa Catarina, as well as to characterize the epidemiological profile and Leishmania species involved. METHODOLOGY/PRINCIPAL FINDINGS: For this cross-sectional study, data from all CL cases from Santa Catarina, Brazil, reported to the Brazilian National Notifiable Diseases Information System from 2001 to 2009 were investigated. Amplification of the kDNA minicircle conserved region followed by restriction fragment length polymorphism (PCR-RFLP was conducted to screen for Leishmania species present in patient biopsy. Overall, 542 CL cases were reported, with majority resulting from autochthonous transmission (n = 401, 73.99% and occurring in urban zones (n = 422, 77.86%. Age, gender, zone of residence, origin of case, clinical form and case outcome were found to differ significantly by region. Imported cases were over seven times more likely to relapse (95% CI 2.56-21.09. Mapping of cases revealed new endemic areas in northeastern Santa Catarina with two species present. With the exception of three L. (Leishmania amazonensis cases (1.20%, majority of PCR positive samples were found to be L. (Viannia braziliensis (n = 248, 98.80%. CONCLUSIONS/SIGNIFICANCE: CL is now endemic in the state of Santa Catarina, Brazil, with case profiles varying significantly by region. L. (V. braziliensis has been identified as the predominant species in the region.

Structuring an integrated care system: interpreted through the enacted diversity of the actors involved – the case of a French healthcare network

Full Text Available Research question: We are looking at the process of structuring an integrated care system as an innovative process that swings back and forth between the diversity of the actors involved, local aspirations and national and regional regulations. We believe that innovation is enriched by the variety of the actors involved, but may also be blocked or disrupted by that diversity. Our research aims to add to other research, which, when questioning these integrated systems, analyses how the actors involved deal with diversity without really questioning it. Case study: The empirical basis of the paper is provided by case study analysis. The studied integrated care system is a French healthcare network that brings together healthcare professionals and various organisations in order to improve the way in which interventions are coordinated and formalised, in order to promote better detection and diagnosis procedures and the implementation of a care protocol. We consider this case as instrumental in developing theoretical proposals for structuring an integrated care system in light of the diversity of the actors involved. Results and discussion: We are proposing a model for structuring an integrated care system in light of the enacted diversity of the actors involved. This model is based on three factors: the diversity enacted by the leaders, three stances for considering the contribution made by diversity in the structuring process and the specific leading role played by those in charge of the structuring process.  Through this process, they determined how the actors involved in the project were differentiated, and on what basis those actors were involved. By mobilizing enacted diversity, the leaders are seeking to channel the emergence of a network in light of their own representation of that network. This model adds to published research on the structuring of integrated care systems.

Spray cleaner is a cleaning product containing compressed 1,1-difluoroethane (HFC-152a) to blow dust off electric devices and other sensitive equipment; however, it is also inhaled to induce euphoria. This report describes three cases of death involving HFC-152a inhalation with spray cleaner under different circumstances. In case 1, death was during inhalation for euphoria with which led to having frostbite. In case 2, death may have been associated with suicidal intention. Case 3 was also considered an accidental autoerotic death. In all three cases, HFC-152a was detected at 99.2-136.2mg/l in blood samples, 94.5-191.9 mg/l in urine samples and 3.6-18.4 mg in the gastric contents according to gas chromatography with flame ionization detection. To prevent death associated with HFC-152a inhalation from spray cleaner, the danger of the sudden death should be announced to people, given the ready availability of commercial products containing HFC-152a.

Parental involvement in the educational process is desirable, although more involvement does not guarantee better results. The aim of this research is to explore the relationship between styles of parental involvement at home and academic performance. A random sample of 26,543 Spanish students was used, with a mean age of 14.4 (SD = 0.75). Two thirds (66.2%) attended a publicly funded school; 49.7% were girls; 87.8% had Spanish nationality; and 73.5% were in the school year corresponding to their age. Different three-level hierarchical-linear models were fitted: student, school, and region (autonomous community). Students whose parents exhibited a more distal or indirect profile of family involvement tended to demonstrate better results than those from homes with a more controlling style. Parental involvement styles have an effect on achievement at an individual and school level, even after accounting for the effect of context or background variables. Given the importance of parental involvement in academic performance, schools should consider it in their family information and training policies. Schools which have more communicative family profiles tend to demonstrate lower levels of intra-school differences in students’ academic performance.

Health systems need efficient and effective innovation decisions to provide maximum benefit to patients, particularly in a climate of financial constraints. Although evidence-based innovations exist for helping to address healthcare-associated infections, the uptake and implementation of these is highly variable and in some cases very slow. To investigate innovation adoption decisions and implementation processes from an organizational perspective, focusing on the implications of stakeholder involvement during the innovation process. Thirty-eight technology adoption decisions and implementation processes were examined through 121 qualitative interviews in 12 National Health Service healthcare organizations across England. Stakeholder involvement varied across organizations with decisions highly exclusive to the infection prevention and control (IPC) team, to highly inclusive of wider organizational members. The context, including organizational culture, previous experience, and logistical factors influenced the level of stakeholder engagement. The timing of stakeholder involvement in the process impacted on: (i) the range of innovations considered; (ii) the technologies selected, and (iii) the success of technology implementation. Cases of non-adoption, discontinued adoption, and of successful implementation are presented to share learning. The potential benefits of stakeholder involvement for 'successful' innovation adoption are presented including a goal-oriented framework for involvement. Key stakeholder involvement can lead to innovation adoption and implementation compatible with structural and cultural contexts, particularly when involvement crosses the phases of initiation, decision-making and implementation. Involving members of the wider healthcare organization can raise the profile of IPC and reinforce efforts to make IPC everybody's business. Copyright © 2012 The Healthcare Infection Society.

The use of Function Parameterisation for the recovery of plasma profiles as a function of flux surface area from spatial point data directly combined with external magnetic measurements is demonstrated in the case of ASDEX electron temperature and density profiles. The extrapolated temperature on the magnetic axis is shown to be more reliable than that obtained from a conventional fitting procedure. (orig.)

Full Text Available Abstract Background Legal requirements for quality assurance in German rehabilitation hospitals include comparisons of providers. Objective is to describe and to compare outcome quality of care offered by three hospitals providing in-patient rehabilitative treatment exemplified for patients with chronic headache. Methods We performed a prospective three center observational study on patients suffering from chronic headache. Patients underwent interventions commonly used according to internal guidelines of the hospitals. Measurements were taken at three points in time (at admission, at discharge and 6 months after discharge. Indicators of outcome quality included pain intensity and frequency of pain, functional ability, depression, quality of life and health related behavior. Analyses of differences amongst the hospitals were adjusted by covariates due to case-mix situation. Results 306 patients from 3 hospitals were included in statistical analysis. Amongst the hospitals, patients differed significantly in age, education, diagnostic subgroups, beliefs, and with respect to some pain-related baseline values (covariates. Patients in all three hospitals benefited from intervention to a clinically relevant degree. At discharge from hospital, outcome quality differed significantly after adjustment according to case-mix only in terms of patients' global assessment of treatment results. Six months after discharge, the only detectable significant differences were for secondary outcomes like improved coping with stress or increased use of self-help. The profiles for satisfaction with the hospital stay showed clear differences amongst patients. Conclusion The results of this case study do not suggest a definite overall ranking of the three hospitals that were compared, but outcome profiles offer a multilayer platform of reliable information which might facilitate decision making.

A 76-year-old man complained of difficulty in urination and miction pain with abacterial pyuria after radiation therapy for prostate cancer. Transurethral resection of the prostate was performed and histopathologically widespread necrosis was observed in the prostate. Thereafter retention of urine and fever occurred and computed tomography scan revealed an abscess of the penile corpus. The abscess was drained, but the fever continued. He developed an abacterial lung abscess and abacterial necrotic ulcerating lesions on his back, his left leg and his lower abdomen. Macroscopic findings demonstrated typical features of pyoderma gangrenosum. Steroid treatment was initiated and the response to steroid therapy was dramatic. Finally urinary diversion using an ileal conduit was performed. We found few cases of pyoderma gangrenosum involving lesions other than those of the skin in the literature. This is the first report of pyoderma gangrenosum involving the prostate gland after radiation therapy for prostate cancer. (author)

Full text of publication follows: Two case studies were presented on experiences with stakeholder involvement in decommissioning projects. The first paper described the development of the United Kingdom Atomic Energy Authority's (UKAEA) stakeholder involvement activities for the Dounreay Nuclear Reactor Test Establishment. The second paper presented the US Nuclear Regulatory Commission regulatory process for decommissioning that includes opportunities for public involvement. The presentation contrasted the stakeholder involvement for two commercial US nuclear power plants (NPPs) that completed decommissioning in 2005, the Trojan NPP and the Maine Yankee NPP. The two case studies highlighted the importance of involving stakeholders in decommissioning projects, and provide important lessons learned. The Dounreay case study demonstrated the UKAEA's determination and commitment to continuously improve its stakeholder engagement program. In 2002, the UKAEA set out to broaden its stakeholder program by improving both public understanding and participation. With regard to public understanding, the UKAEA committed to keep the public informed on decommissioning developments, and ensure that communication was in an understandable form. To improve participation, the UKAEA actively worked to identify and engage stakeholders. The UKAEA then made efforts to involve stakeholders in decision-making activities, including the use of stakeholder panels to discuss and consider options for specific aspects of the Dounreay decommissioning and site restoration plan. In 2004, the UKAEA commissioned an independent review of its stakeholder involvement program to assess the program's effectiveness and benchmark it against best practices. The program was found to be useful, and positive feedback was provided on the use of stakeholder panels and the UKAEA's determination to deliver a broad based and effective stakeholder strategy. Recommendations to UKAEA included involving stakeholders

Meta-analysis of microarray data is increasingly important, considering both the availability of multiple platforms using disparate technologies and the accumulation in public repositories of data sets from different laboratories. We addressed the issue of comparing gene expression profiles from two microarray platforms by devising a standardized investigative strategy. We tested this procedure by studying MDA-MB-231 cells, which undergo apoptosis on treatment with resveratrol. Gene expression profiles were obtained using high-density, short-oligonucleotide, single-color microarray platforms: GeneChip (Affymetrix) and CodeLink (Amersham). Interplatform analyses were carried out on 8414 common transcripts represented on both platforms, as identified by LocusLink ID, representing 70.8% and 88.6% of annotated GeneChip and CodeLink features, respectively. We identified 105 differentially expressed genes (DEGs) on CodeLink and 42 DEGs on GeneChip. Among them, only 9 DEGs were commonly identified by both platforms. Multiple analyses (BLAST alignment of probes with target sequences, gene ontology, literature mining, and quantitative real-time PCR) permitted us to investigate the factors contributing to the generation of platform-dependent results in single-color microarray experiments. An effective approach to cross-platform comparison involves microarrays of similar technologies, samples prepared by identical methods, and a standardized battery of bioinformatic and statistical analyses.

The current study explored the multifaceted nature of the mother-adolescent coparental relationship with data from 167 Mexican-origin adolescent mothers and their own mothers at ten months post-childbirth. Profiles of mother-adolescent coparenting were created with latent profile analysis using adolescents’ reports of three dimensions of coparenting (communication, involvement and conflict). Four profiles were identified: (a) Harmonious Coparents (equal involvement, high communication, low conflict); (b) Harmonious-Adolescent Primary (adolescent is more involved than mother, high communication, low conflict); (c) Conflictual Coparents (equal involvement, high communication, high conflict); and (d) Conflictual-Adolescent Primary (adolescent is more involved than mother, moderate communication, high conflict). Families characterized by high mother-daughter conflict and psychological control prior to childbirth were more likely to belong in the Conflictual Coparents profile. In addition, adolescents’ and mothers’ depressive symptoms and parenting efficacy after childbirth were linked to profile membership, such that the Harmonious-Adolescent Primary profile reported the most positive adjustment patterns, whereas profiles with high coparental conflict (i.e., Conflictual Coparenting and Conflictual-Adolescent Primary profiles) showed the least positive adjustment patterns. Discussion considers the applied implications of identifying precursors to healthy and problematic mother-daughter coparenting for families of adolescent mothers in the early years of parenting.

Prior person-centered research has consistently identified a subgroup of highly religious participants that uses significantly less alcohol when compared to the other subgroups. The construct of religious motivation is absent from existing examinations of the nuanced combinations of religiousness dimensions within persons, and alcohol expectancy valuations have yet to be included as outcome variables. Variable-centered approaches have found religious motivation and alcohol expectancy valuations to play a protective role against individuals' hazardous alcohol use. The current study examined latent religiousness profiles and hazardous alcohol use in a large, multisite sample of ethnically diverse college students. The sample consisted of 7412 college students aged 18-25 (M age = 19.77, SD age = 1.61; 75% female; 61% European American). Three latent profiles were derived from measures of religious involvement, salience, and religious motivations: Quest-Intrinsic Religiousness (highest levels of salience, involvement, and quest and intrinsic motivations; lowest level of extrinsic motivation), Moderate Religiousness (intermediate levels of salience, involvement, and motivations) and Extrinsic Religiousness (lowest levels of salience, involvement, and quest and intrinsic motivations; highest level of extrinsic motivation). The Quest-Intrinsic Religiousness profile scored significantly lower on hazardous alcohol use, positive expectancy outcomes, positive expectancy valuations, and negative expectancy valuations, and significantly higher on negative expectancy outcomes, compared to the other two profiles. The Extrinsic and Moderate Religiousness profiles did not differ significantly on positive expectancy outcomes, negative expectancy outcomes, negative expectancy valuations, or hazardous alcohol use. The results advance existing research by demonstrating that the protective influence of religiousness on college students' hazardous alcohol use may involve high levels on

Full Text Available The objective of this study was to identify profiles of high school students, based on variables related to academic performance, socioeconomic status, cultural capital and family organization. A total of 21,724 high school students, from the five municipalities of the state of Baja California, took part. A K-means cluster analysis was performed to identify the profiles. The analyses identified two clearly-defined clusters: Cluster 1 grouped together students with high academic performance and who achieved higher scores for socioeconomic status, cultural capital and family involvement, whereas Cluster 2 brought together students with low academic achievement, and who also obtained lower scores for socioeconomic status and cultural capital, and had less family involvement. It is concluded that the family variables analyzed form student profiles that can be related to academic achievement.

It is good practice for the public to be involved in developing research ideas into grant applications. Some positive accounts of this process have been published, but little is known about when their reactions are negative and when researchers' ideas are abandoned. To present a case study account of when an academic-led idea for funding was not supported by stroke survivors and carers who were asked to contribute to its development, together with a reflection on the implications of the case from all the stakeholders involved. A reflective case study of a research idea, developed by an academic researcher, on which stakeholders were consulted. University researchers, clinicians, public involvement managers, and stroke survivors and carers from the NIHR's Stroke Research Network. Although the idea met with the approval of health professionals, who were keen to develop it into a funding bid, the stroke survivors and carers did not think the idea worth pursuing. This lack of patient and carer support led to the idea being abandoned. Reflecting on this, those involved in the consultation believed that the savings accrued from abandoning the idea, in terms of ensuring that public money is not wasted, should be seen as an important benefit of public involvement in the research process. Little is known about the role of the public in the abandonment of research ideas. We recommend that further research is undertaken into this important contribution that patients and the public can make to health research. © 2012 John Wiley & Sons Ltd.

Full Text Available Heritable factors are evidently involved in prostate cancer (PrCa carcinogenesis, but currently, genetic markers are not routinely used in screening or diagnostics of the disease. More precise information is needed for making treatment decisions to distinguish aggressive cases from indolent disease, for which heritable factors could be a useful tool. The genetic makeup of PrCa has only recently begun to be unravelled through large-scale genome-wide association studies (GWAS. The thus far identified Single Nucleotide Polymorphisms (SNPs explain, however, only a fraction of familial clustering. Moreover, the known risk SNPs are not associated with the clinical outcome of the disease, such as aggressive or metastasised disease, and therefore cannot be used to predict the prognosis. Annotating the SNPs with deep clinical data together with miRNA expression profiles can improve the understanding of the underlying mechanisms of different phenotypes of prostate cancer.In this study microRNA (miRNA profiles were studied as potential biomarkers to predict the disease outcome. The study subjects were from Finnish high risk prostate cancer families. To identify potential biomarkers we combined a novel non-parametrical test with an importance measure provided from a Random Forest classifier. This combination delivered a set of nine miRNAs that was able to separate cases from controls. The detected miRNA expression profiles could predict the development of the disease years before the actual PrCa diagnosis or detect the existence of other cancers in the studied individuals. Furthermore, using an expression Quantitative Trait Loci (eQTL analysis, regulatory SNPs for miRNA miR-483-3p that were also directly associated with PrCa were found.Based on our findings, we suggest that blood-based miRNA expression profiling can be used in the diagnosis and maybe even prognosis of the disease. In the future, miRNA profiling could possibly be used in targeted screening

Chemical-genetic profiling of inhibitory compounds can lead to identification of their modes of action. These profiles can help elucidate the complex interactions between small bioactive compounds and the cell machinery, and explain putative gene function(s). Colony size reduction was used to investigate the chemical-genetic profile of cycloheximide, 3-amino-1,2,4-triazole, paromomycin, streptomycin and neomycin in the yeast Saccharomyces cerevisiae. These compounds target the process of protein biosynthesis. More than 70,000 strains were analyzed from the array of gene deletion mutant yeast strains. As expected, the overall profiles of the tested compounds were similar, with deletions for genes involved in protein biosynthesis being the major category followed by metabolism. This implies that novel genes involved in protein biosynthesis could be identified from these profiles. Further investigations were carried out to assess the activity of three profiled genes in the process of protein biosynthesis using relative fitness of double mutants and other genetic assays. Chemical-genetic profiles provide insight into the molecular mechanism(s) of the examined compounds by elucidating their potential primary and secondary cellular target sites. Our follow-up investigations into the activity of three profiled genes in the process of protein biosynthesis provided further evidence concerning the usefulness of chemical-genetic analyses for annotating gene functions. We termed these genes TAE2, TAE3 and TAE4 for translation associated elements 2-4.

No data are available regarding the success of DNA Short Tandem Repeat (STR) profiling from degraded skeletal remains in Guatemala. Therefore, DNA profiling success rates relating to 2595 skeletons from eleven cases at the Forensic Anthropology Foundation of Guatemala (FAFG) are presented. The typical postmortem interval was 30 years. DNA was extracted from bone powder and amplified using Identifiler and Minifler. DNA profiling success rates differed between cases, ranging from 50.8% to 7.0%, the overall success rate for samples was 36.3%. The best DNA profiling success rates were obtained from femur (36.2%) and tooth (33.7%) samples. DNA profiles were significantly better from lower body bones than upper body bones (p = <0.0001). Bone samples from males gave significantly better profiles than samples from females (p = <0.0001). These results are believed to be related to bone density. The findings are important for designing forensic DNA sampling strategies in future victim recovery investigations. © 2016 American Academy of Forensic Sciences.

The gene repertoire regulating vertebrate biomineralization is poorly understood. Dental enamel, the most highly mineralized tissue in mammals, differs from other calcifying systems in that the formative cells (ameloblasts) lack remodeling activity and largely degrade and resorb the initial extracellular matrix. Enamel mineralization requires that ameloblasts undergo a profound functional switch from matrix-secreting to maturational (calcium transport, protein resorption) roles as mineralization progresses. During the maturation stage, extracellular pH decreases markedly, placing high demands on ameloblasts to regulate acidic environments present around the growing hydroxyapatite crystals. To identify the genetic events driving enamel mineralization, we conducted genome-wide transcript profiling of the developing enamel organ from rat incisors and highlight over 300 genes differentially expressed during maturation. Using multiple bioinformatics analyses, we identified groups of maturation-associated genes whose functions are linked to key mineralization processes including pH regulation, calcium handling, and matrix turnover. Subsequent qPCR and Western blot analyses revealed that a number of solute carrier (SLC) gene family members were up-regulated during maturation, including the novel protein Slc24a4 involved in calcium handling as well as other proteins of similar function (Stim1). By providing the first global overview of the cellular machinery required for enamel maturation, this study provide a strong foundation for improving basic understanding of biomineralization and its practical applications in healthcare.

Nur Laili

2016-12-01

Full Text Available Adoption of new technologies is a process that involves technological learning and penetration of new products into the market. Within the process of new technologies adoption, government usually intervened by providing incentives, in order to support the technology adoption to be succeed. This paper examines the effectiveness of incentives for the sustainability of reverse osmosis (RO membrane technology adoption. The study conducted through single case study on SWRO installation in Mandangin Island, East Java, Indonesia. Results of case study indentify the existence of government incentive in the form of direct subsidies to decrease the price of clean water. Although successful in reducing the price of water, but effectiveness of the subsidy on the sustainability of SWRO is still low, which is operates only 30% in a year. Further analysis shows that these subsidies actually be counter-productive to the sustainability of SWRO installation.

To analyze the risk profile of patients with diabetes who seek care from hospital emergency departments and emergency department involvement in preventing cardiovascular complications in these patients. Cross-sectional analysis of case series from 2 Spanish hospital emergency departments. We included all patients with a history or final diagnosis of diabetes mellitus who were treated in the emergency department between November 1, 2010, and June 30, 2011. Each patient's cardiovascular risk profile was analyzed. The main outcome was the appropriate of prescribed treatment to prevent cardiovascular complications according to the 2012 guidelines of the American Diabetes Association on the patient's discharge from emergency care. A total of 298 patients were included; 275 (92%) had type II diabetes. Ninety percent of the series (269 patients) had at least 1 cardiovascular risk factor and 147 (49%) had prior target organ damage; target organ damage was newly diagnosed in 41 (14%). Fifty-eight percent (172 patients) were discharged home from the emergency department. Although 215 patients (72%) were not adhering to at least 1 previously prescribed preventive treatment and 30 (10%) were not adhering to any prescribed treatment, drug prescriptions were modified only in 1.1% to 3.3% of patients and no follow-up was recommended in 42 cases (24%). Although diabetic patients treated in emergency departments are at high risk for cardiovascular complications, their visit is not used to optimize preventive treatment for these complications or ensure appropriate follow-up.

Patients with pulmonary and pulmonary plus extrapulmonary sarcoidosis differ in symptom severity and health status impairment. To date there is no information on differences in clinical and laboratory parameters between these phenotypes and limited information on extrapulmonary involvement in Czech sarcoidosis patients exists. We therefore compared clinical data (age, gender, organ involvement, lung function tests) and laboratory data (blood counts, bronchoalveolar fluid (BAL) cellular profile, serum levels of CRP, SACE, sIL-2R, neopterin) between patients with newly diagnosed pulmonary sarcoidosis (n=107) and those with pulmonary plus extrapulmonary sarcoidosis (n=54). Extrapulmonary sarcoidosis was diagnosed in 33% of patients, mostly affecting lymph nodes and skin and having hypercalciuria. There was no difference in the prevalence of extrapulmonary sarcoidosis between genders. Patients with extrapulmonary sarcoidosis were older and mostly non-smokers when compared to those with limited pulmonary form. X-ray Stage I and erythema nodosum were less frequent in extrapulmonary disease. Serum levels of CRP, SACE, sIL-2R and neopterin and BAL cellular profile did not differ between both phenotypes. We observed lower platelets, FEV1, VC, and BAL CD19+ in females with extrapulmonary involvement than in those with pulmonary disease. Affected lymph nodes, skin and hypercalciuria were the most common in sarcoidosis patients with extrapulmonary involvement. Pulmonary sarcoidosis did not differ in clinical and routine laboratory parameters from pulmonary plus extrapulmonary sarcoidosis. Observation of low platelets, VC, FEV1 and BAL CD19+ in females with extrapulmonary sarcoidosis needs further verification in larger cohort.

Failure of the inflatable penile prosthesis due to abnormal folding of a low-profile reservoir – A selected case from an overall series and systematic review

Full Text Available We present a case from a running series of inflatable penile prosthesis failure due to improper folding of the Conceal™ reservoir. The Conceal™ Low-Profile reservoir gained popularity due to claims of improved cosmesis and ease of implantation. As the number of patients receiving this and other low-profile reservoirs increases, it is imperative to review and document any novel complications. While the Conceal™ reservoir may be preferred in ectopic placement, it may be more prone to fluid lockout facilitated by conformational change. Our review did not identify prior reports of improper folding, which we believe is unique to these low-profile reservoirs.

Otitis media is a well-known condition and its infra-temporal and intracranial complications are extremely rare because of the widespread usage of antibiotic treatment. We report a case of 63-year-old female with complaints of right-sided facial pain and diplopia. She had a history of acute otitis media before 4 months of admission to our neurology unit. Neurological examination showed that total ophthalmoplegia with ptosis, mydriasis, decreased vision and loss of pupil reflex on the right side. In addition, there was involvement of 5th and 7th cranial nerves. Neurological and radiological follow-up examinations demonstrated Jacod's Syndrome with unusual facial nerve damage and infection in aetiology. Sinusitis is the most common aetiology, but there are a few cases reported Jacod's Syndrome originating from otitis media.

Experimental quantum annealing: case study involving the graph isomorphism problem.

Zick, Kenneth M; Shehab, Omar; French, Matthew

2015-06-08

Quantum annealing is a proposed combinatorial optimization technique meant to exploit quantum mechanical effects such as tunneling and entanglement. Real-world quantum annealing-based solvers require a combination of annealing and classical pre- and post-processing; at this early stage, little is known about how to partition and optimize the processing. This article presents an experimental case study of quantum annealing and some of the factors involved in real-world solvers, using a 504-qubit D-Wave Two machine and the graph isomorphism problem. To illustrate the role of classical pre-processing, a compact Hamiltonian is presented that enables a reduced Ising model for each problem instance. On random N-vertex graphs, the median number of variables is reduced from N(2) to fewer than N log2 N and solvable graph sizes increase from N = 5 to N = 13. Additionally, error correction via classical post-processing majority voting is evaluated. While the solution times are not competitive with classical approaches to graph isomorphism, the enhanced solver ultimately classified correctly every problem that was mapped to the processor and demonstrated clear advantages over the baseline approach. The results shed some light on the nature of real-world quantum annealing and the associated hybrid classical-quantum solvers.

Lee, Sung Sik; Jang, Byoung Gyu; Kim, Young H.

2002-01-01

The computer simulation has been done for non-insulated and insulated pipes which are vacant or half filled with liquid. The simulation results showed that the density profile on the radiography is continuous and symmetrical around the center of pipe in the case of vacant pipe. On the other hand the density profiles are not symmetrical and depend on geometrical setting for radiography in the case of half filled pipes. Finally, experimental testing on a non-insulated carbon steel pipe with artificial notches of different depth is carried out using Ir-192 and industrial film. Comparing the measured density profile on the radiograph to the calculated one, it has been shown that it is possible to evaluate thickness variation by measuring density profile on a radiograph

Adaptive Sensing Based on Profiles for Sensor Systems

Directory of Open Access Journals (Sweden)

Yoshiteru Ishida

2009-10-01

Full Text Available This paper proposes a profile-based sensing framework for adaptive sensor systems based on models that relate possibly heterogeneous sensor data and profiles generated by the models to detect events. With these concepts, three phases for building the sensor systems are extracted from two examples: a combustion control sensor system for an automobile engine, and a sensor system for home security. The three phases are: modeling, profiling, and managing trade-offs. Designing and building a sensor system involves mapping the signals to a model to achieve a given mission.

Microsomal prostaglandin E synthase-1, ephrins, and ephrin kinases as suspected therapeutic targets in arthritis: exposed by "criminal profiling".

Science.gov (United States)

Romanovsky, Andrej A; Ivanov, Andrei I; Petersen, Scott R

2006-06-01

Feeding information obtained in one criminal case into the profile of another crime often helps to solve the latter. The literature on two different "crimes," namely, acute systemic inflammation and arthritis (including osteoarthritis [OA] and rheumatoid arthritis [RA] deals largely with the same "gang" of inflammatory mediators, such as prostaglandin (PG) E2. Early investigations suggested that microsomal PGE synthase-1 (mPGES-1; a terminal PGE2-synthesizing enzyme) plays a pivotal role in bacterial lipopolysaccharide (LPS)-induced systemic inflammation, but overlooked the possibility that the same enzyme could be involved in OA or RA. Later studies showed that mPGES-1 is indeed a key perpetrator in arthritic diseases, a fact that could have been predicted earlier by pooling the new knowledge about mPGES-1 into the profile of arthritic diseases. In this review, we analyze our recent study on the expression of erythropoietin-producing hepatocellular (Eph) receptor kinases and their ligands, ephrins, in LPS-induced systemic inflammation. By pooling these results together with literature data into the profile of RA, we conclude that Eph kinases and ephrins are prime suspects for being involved in the pathogenesis of RA. We further conjecture that the involvement of Eph kinases and ephrins may be realized via the induction of angiogenesis in the inflamed joint, promotion of leukocyte infiltration, and activation of the infiltrated cells. Studies to test this new hypothesis seem warranted, and our prediction is that the "smoking gun" will be found.

To examine the influence of quarter outcome and the margin of the score differential on both the physical activity profile and skill performance of players during professional Australian Football matches. Prospective, longitudinal. Physical activity profiles were assessed via microtechnology (Global Positioning System and accelerometer) from 40 professional AF players from the same team during 15 Australian Football League games. Skill performance measures (involvement and effectiveness) and player rank scores (Champion Data(©) Rank) were provided by a commercial statistical provider. The physical performance variables, skill involvements and individual player performance scores were expressed relative to playing time for each quarter. The influence of the quarter result (i.e. win vs. loss) and score margin (i.e. small: 19 points) on activity profile and skill involvements and skill efficiency performance of players were examined. Skill involvements (total disposals/min, long kicks/min, marks/min, running bounces/min and player rank/min) were greater in quarters won (all p14.5 km h(-1), HSR/min), sprints/min and peak speed were higher in losing quarters (all pProfessional AF players are likely to have an increased physical activity profile and decreased skill involvement and proficiency when their team is less successful.

Vertical grid of retrieved atmospheric profiles

Ceccherini, Simone; Carli, Bruno; Raspollini, Piera

2016-01-01

The choice of the vertical grid of atmospheric profiles retrieved from remote sensing observations is discussed considering the two cases of profiles used to represent the results of individual measurements and of profiles used for subsequent data fusion applications. An ozone measurement of the MIPAS instrument is used to assess, for different vertical grids, the quality of the retrieved profiles in terms of profile values, retrieval errors, vertical resolutions and number of degrees of freedom. In the case of individual retrievals no evident advantage is obtained with the use of a grid finer than the one with a reduced number of grid points, which are optimized according to the information content of the observations. Nevertheless, this instrument dependent vertical grid, which seems to extract all the available information, provides very poor results when used for data fusion applications. A loss of about a quarter of the degrees of freedom is observed when the data fusion is made using the instrument dependent vertical grid relative to the data fusion made using a vertical grid optimized for the data fusion product. This result is explained by the analysis of the eigenvalues of the Fisher information matrix and leads to the conclusion that different vertical grids must be adopted when data fusion is the expected application. - Highlights: • Data fusion application is taken into account for the choice of the vertical grid. • The study is performed using ozone profiles retrieved from MIPAS measurements. • A very fine vertical grid is not needed for the analysis of a single instrument. • The instrument dependent vertical grid is not the best choice for data fusion. • A data fusion dependent vertical grid must be used for profiles that will be fused.

Cross-sectional study in which data were collected from medical records of patients in the period from July to December 2008. The profile of the patients involved was formed by subjects mostly male young subjects, victims of trauma from accidents, especially those with motorcycles or car runover. On the other hand,the most frequent traumas associated with urban violence were perforations by gunshot and stab wounds. The primary injury presented by these individuals was exposed fracture of the femur and the most common treatment was external fixation. The most frequent in-hospital complication was wound infection, which required another surgical approach. Most inpatients were discharged and only one death was reported during this period. The results of this study corroborate those from other institutions in the country, which may contribute to elaborate public policies for accidents and violence prevention.

The preparation of Country Nuclear Power Profiles was initiated within the framework of the IAEA`s programme for nuclear power plant performance assessment and feedback. It responded to a need for a database and a technical document containing a description of the energy and economic situation and the primary organizations involved in nuclear power in IAEA Member States. The task was included in the IAEA`s programmes for 1993/1994 and 1995/1996. In March 1993, the IAEA organized a Technical Committee meeting to discuss the establishment of country data ``profiles``, to define the information to be included in the profiles and to review the information already available in the IAEA. Two expert meetings were convened in November 1994 to provide guidance to the IAEA on the establishment of the country nuclear profiles, on the structure and content of the profiles, and on the preparation of the publication and the electronic database. In June 1995, an Advisory Group meeting provided the IAEA with comprehensive guidance on the establishment and dissemination of an information package on industrial and organizational aspects of nuclear power to be included in the profiles. The group of experts recommended that the profiles focus on the overall economic, energy and electricity situation in the country and on its nuclear power industrial structure and organizational framework. In its first release, the compilation would cover all countries with operating power plants by the end of 1995. It was also recommended to further promote information exchange on the lessons learned from the countries engaged in nuclear programmes. For the preparation of this publication, the IAEA received contributions from the 29 countries operating nuclear power plants and Italy. A database has been implemented and the profiles are supporting programmatic needs within the IAEA; it is expected that the database will be publicly accessible in the future. Refs, figs, tabs.

A novel method for decomposing electricity feeder load into elementary profiles from customer information

Highlights: •Use of aggregated electricity load profiles and customer description at feeder level. •Statistical recovery of elementary load profiles with customer categorization. •Generation of load demand profiles for unknown feeders and new local areas. •Relevancy of the different categorizations. -- Abstract: To plan a distribution grid involves making a long-term forecast of sub-hourly demand, which requires modeling the demand and its dynamics with aggregated measurement data. Distribution system operators (DSOs) have been recording electricity sub-hourly demand delivered by their medium-voltage feeders (around 1000—10,000 customers) for several years. Demand profiles differ widely among the various considered feeders. This is partly due to the varying mix of customer categories from one feeder to another. To overcome this issue, elementary demand profiles are often associated with customer categories and then combined according to a mix description. This paper presents a novel method to estimate elementary profiles that only requires several feeder demand curves and a description of customers. The method relies on a statistical blind source model and a new estimation procedure based on the augmented Lagrangian method. The use of feeders to estimate elementary profiles means that measurements are fully representative and continuously updated. We illustrate the proposed method through a case study comprising around 1000 feeder demand curves operated by the main French DSO Enedis. We propose an application o that uses the obtained profiles to evaluate the contribution of any set of new customers to a feeder peak load. We show that profiles enable a simulation of new unmeasured areas with errors of around 20%. We also show how our method can be used to evaluate the relevancy of different customer categorizations.

Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-associated liver disease with potentially deleterious consequences for the fetus, particularly when maternal serum bile-acid concentration >40 μM. However, the etiology and pathogenesis of ICP remain elusive. To reveal the underlying molecular mechanisms for the association of maternal serum bile-acid level and fetal outcome in ICP patients, DNA microarray was applied to characterize the whole-genome expression profiles of placentas from healthy women and women diagnosed with ICP. Thirty pregnant women recruited in this study were categorized evenly into three groups: healthy group; mild ICP, with serum bile-acid concentration ranging from 10-40 μM; and severe ICP, with bile-acid concentration >40 μM. Gene Ontology analysis in combination with construction of gene-interaction and gene co-expression networks were applied to identify the core regulatory genes associated with ICP pathogenesis, which were further validated by quantitative real-time PCR and histological staining. The core regulatory genes were mainly involved in immune response, VEGF signaling pathway and G-protein-coupled receptor signaling, implying essential roles of immune response, vasculogenesis and angiogenesis in ICP pathogenesis. This implication was supported by the observed aggregated immune-cell infiltration and deficient blood vessel formation in ICP placentas. Our study provides a system-level insight into the placental gene-expression profiles of women with mild or severe ICP, and reveals multiple molecular pathways in immune response and blood vessel formation that might contribute to ICP pathogenesis.

Some examples of the use of gravity exploration methods in landfills were published recently. However, density contrast between the landfill and the host media as well as the cost involved may be limiting factors to the application of gravimetry to this problem. Herein a case study of the application of gravity methods to the internal characterization of a sealed landfill is presented. This landfill is installed in recent low-density quaternary sand formations. Two north–south gravity profiles were carried out. The first profile crossed the landfill at its centre, whilst a second profile was done some distance away from the landfill to provide general regional information. The first profile was modelled in order to obtain lateral variations of density within the landfill that might be caused by different types of waste and/or the age of the waste deposits. Gravity modelling and interpretation were supported with data from resistivity profiles carried out in the immediate vicinity of the gravity measurements, i.e. the resistivity profiles interpretation results constrained the thickness of landfill deposits

Nowadays traffic accidents, which have high mortality and morbidity, are an important public health problem. The association between the use of alcohol and/or drugs by drivers and the increased risk of traffic accidents with a high risk of death and injury has been well described in the literature. This study aimed to review the incidence of cases of driving under the influence of drugs (DUID) among all cases of driving under the influence (DUI) of alcohol and/or other drugs involved in traffic accidents and to evaluate the type of the psychoactive drugs (with or without alcohol) detected in blood samples in Istanbul and its surrounding area. This study is the first investigation on the subject of DUID cases in Turkey. The reports of the Istanbul Toxicology Department of the Council of Forensic Medicine (Turkey) on suspected DUID cases involved in traffic accidents between 1 July 2010 and 30 June 2011 were retrospectively reviewed for alcohol and/or drug use. Alcohol analysis was requested in 4274 suspected DUI cases, whereas drug along with alcohol analysis was requested in only 91. The rate of suspected DUID cases (n = 91) among the suspected DUI cases (n = 4274) was only 2.1% and in this study, we evaluated only the DUID cases in detail. Alcohol was present in 44% of suspected DUID cases. Psychoactive drugs were present in 15.4% of cases. The incidence among 46 confirmed DUID cases was found to be 17.4% for cannabis, 8.7% for benzodiazepines, 4.3% for barbiturates, 4.3% for antidepressants, 2.2% for cocaine and 2.2% for amphetamines. Although there is a zero-tolerance approach for DUID in the Turkish regulations, it is not well recognised and not inspected by police and legal authorities who are responsible for taking measures in traffic accidents and for routine traffic controls in Turkey. It is concluded that psychoactive drugs should be checked as well as alcohol in all traffic accident cases and roadside controls. Copyright © 2013 Elsevier Ltd and Faculty

Full Text Available Abstract Background Chemical-genetic profiling of inhibitory compounds can lead to identification of their modes of action. These profiles can help elucidate the complex interactions between small bioactive compounds and the cell machinery, and explain putative gene function(s. Results Colony size reduction was used to investigate the chemical-genetic profile of cycloheximide, 3-amino-1,2,4-triazole, paromomycin, streptomycin and neomycin in the yeast Saccharomyces cerevisiae. These compounds target the process of protein biosynthesis. More than 70,000 strains were analyzed from the array of gene deletion mutant yeast strains. As expected, the overall profiles of the tested compounds were similar, with deletions for genes involved in protein biosynthesis being the major category followed by metabolism. This implies that novel genes involved in protein biosynthesis could be identified from these profiles. Further investigations were carried out to assess the activity of three profiled genes in the process of protein biosynthesis using relative fitness of double mutants and other genetic assays. Conclusion Chemical-genetic profiles provide insight into the molecular mechanism(s of the examined compounds by elucidating their potential primary and secondary cellular target sites. Our follow-up investigations into the activity of three profiled genes in the process of protein biosynthesis provided further evidence concerning the usefulness of chemical-genetic analyses for annotating gene functions. We termed these genes TAE2, TAE3 and TAE4 for translation associated elements 2-4.

Full Text Available Abstract Background Fasciola hepatica primarily involves the liver, however in some exceptional situations other organs have been reported to be involved. The ectopic involvement is either a result of Parasite migration or perhaps eosinophilic reaction. Case presentation Here we report a known case of multiple myeloma who was under treatment with prednisolone and melphalan. He was infected by Fasciola hepatica, which involved many organs and the lesions were mistaken with metastatic ones. Discussion Presented here is a very unusual case of the disease, likely the first case involving the pancreas, spleen, and kidney, as well as the liver.

Central nervous system (CNS) manifestations in acquired immunodeficiency syndrome (AIDS) patients are an early and common feature. The spectrum of AIDS-related CNS diseases are encephalitis caused by the human immunodeficiency virus(HIV) itself, opportunistic infection, infarct and malignancy. We experienced two cases of CNS involvement in AIDS and they were serologically diagnosed as HIV encephalitis and CNS toxoplasmosis, respectively. In the case of the HIV encephalitis patient, brain MRI showed a non-enhancing lesion with high signal intensity on T2WI and low signal on T1WI and there was no mass effect on the right frontal lobe, periventricular white matter, splenium of the corpus callosum or bilateral basal ganglia. In the other case of CNS toxoplasmosis, MR showed multiple nodular and rim enhanced mass lesions in the right basal ganglia, thalamus and periventricular white matter, which were of low signal intensity on T1WI and of high intensity on T2WI. We thus report the related MRI findings

Stachlewska, Iwona S.; Costa-Surós, Montserrat; Althausen, Dietrich

2017-09-01

Water vapor mixing ratio and relative humidity profiles were derived from the multi-wavelength Raman PollyXT lidar at the EARLINET site in Warsaw, using the Rayleigh molecular extinction calculation based on atmospheric temperature and pressure from three different sources: i) the standard atmosphere US 62, ii) the Global Data Assimilation System (GDAS) model output, and iii) the WMO 12374 radiosoundings launched at Legionowo. With each method, 136 midnight relative humidity profiles were obtained for lidar observations from July 2013 to August 2015. Comparisons of these profiles showed in favor of the latter method (iii), but it also indicated that the other two data sources could replace it, if necessary. Such use was demonstrated for an automated retrieval of water vapor mixing ratio from dusk until dawn on 19/20 March 2015; a case study related to an advection of biomass burning aerosol from forest fires over Ukraine. Additionally, an algorithm that applies thresholds to the radiosounding relative humidity profiles to estimate macro-physical cloud vertical structure was used for the first time on the Raman lidar relative humidity profiles. The results, based on a subset of 66 profiles, indicate that below 6 km cloud bases/tops can be successfully obtained in 53% and 76% cases from lidar and radiosounding profiles, respectively. Finally, a contribution of the lidar derived mean relative humidity to cloudy conditions within the range of 0.8 to 6.2 km, in comparison to clear-sky conditions, was estimated.

Coexpression of mRNAs under multiple conditions is commonly used to infer cofunctionality of their gene products despite well-known limitations of this “guilt-by-association” (GBA) approach. Recent advancements in mass spectrometry-based proteomic technologies have enabled global expression profiling at the protein level; however, whether proteome profiling data can outperform transcriptome profiling data for coexpression based gene function prediction has not been systematically investigated. Here, we address this question by constructing and analyzing mRNA and protein coexpression networks for three cancer types with matched mRNA and protein profiling data from The Cancer Genome Atlas (TCGA) and the Clinical Proteomic Tumor Analysis Consortium (CPTAC). Our analyses revealed a marked difference in wiring between the mRNA and protein coexpression networks. Whereas protein coexpression was driven primarily by functional similarity between coexpressed genes, mRNA coexpression was driven by both cofunction and chromosomal colocalization of the genes. Functionally coherent mRNA modules were more likely to have their edges preserved in corresponding protein networks than functionally incoherent mRNA modules. Proteomic data strengthened the link between gene expression and function for at least 75% of Gene Ontology (GO) biological processes and 90% of KEGG pathways. A web application Gene2Net (http://cptac.gene2net.org) developed based on the three protein coexpression networks revealed novel gene-function relationships, such as linking ERBB2 (HER2) to lipid biosynthetic process in breast cancer, identifying PLG as a new gene involved in complement activation, and identifying AEBP1 as a new epithelial-mesenchymal transition (EMT) marker. Our results demonstrate that proteome profiling outperforms transcriptome profiling for coexpression based gene function prediction. Proteomics should be integrated if not preferred in gene function and human disease studies

Gout is a common inflammatory crystal deposition disease that occurs in many joints throughout the body. Active gout is most often associated with painful synovitis causing searing joint pains, but gout can also produce large masses of space-occupying deposits called tophi. Tophi are most frequently seen in juxta-articular locations with or without bony erosion and are often misdiagnosed as degenerative joint disease. Soft tissue deposits and tendon involvement are also known manifestations of gout, but can present with indeterminate and alarming findings on imaging. We present three cases of tophaceous gout mimicking aggressive neoplasms in the extensor mechanism of the knee. All cases presented as extensor tendon masses eroding into the patella, with imaging findings initially concerning for primary musculoskeletal malignancy.

2014-03-01

We conducted a study on the effect of fingerprint enhancement methods on subsequent short tandem repeat profiling. First, we performed a study typing blood traces deposited on 5 different surfaces, treated with 8 types of dactyloscopic powders. Three different DNA extraction methods were used. Subsequently, we analyzed latent fingerprints on the same 5 surfaces enhanced with the 8 different powders used in the first part of the study. This study has demonstrated that DNA profiling can be performed on fingerprints left on different substrates, and the substrate will affect the amount of DNA that can be recovered for DNA typing. In the first phase of the study, a profile was obtained in 92% of the 120 samples analyzed; in the second part, in 55% of the 80 samples analyzed, we obtained a profile complete in 32.5% of the cases. From the results obtained, it seems that the powders used in latent fingerprints enhancement, rather than having a direct inhibitory effect on extraction and amplification of DNA, may cause partial degradation of DNA, reducing the efficiency of amplification reaction. It should not be forgotten that these results were obtained under laboratory conditions, and in real caseworks, there may still be different problems involved.

Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only rare cases of ectopic PTC without any evidence of occult thyroid cancer in the orthotopic thyroid or cervical lymph nodes have been reported. We report on a 39 year old woman who was operated for a mediastinal mass. The initial diagnosis was a malignant thymic lesion, which was later confirmed to be a papillary thyroid carcinoma. Consequently, total thyroidectomy was performed and pathology report showed normal thyroid tissue with no evidence of any neoplastic involvement. Until now, only one similar case has been reported

Tumor Molecular Profiling for an Individualized Approach to the Treatment of Hepatocellular Carcinoma: A Patient Case Study

2018-04-01

Full Text Available Hepatocellular carcinoma (HCC is increasing in incidence, and the associated mortality rate remains among the highest. For advanced HCC, sorafenib has been shown to slightly prolong survival, and regorafenib and nivolumab, both recently approved by the United States Food and Drug Administration (FDA, may produce clinical benefits to a limited extent. Systemic chemotherapy has been shown to produce a modest response, but there is no clinically valid biomarker that can be used to predict which patients may benefit. In this case study, we present two patients with metastatic HCC, they received systemic treatment using capecitabine, oxaliplatin, and either bevacizumab or sorafenib. The tumor response to treatment was determined by the progression-free survival (PFS. Molecular profiling of the tumors showed differential expression of biochemical markers and different mutational status of the TP53 and β-catenin (CTNNB1 genes. We hypothesize that the PFS correlates with the tumor molecular profiles, which may be predictive of the therapeutic response to systemic chemotherapy. Further investigation is indicated to correlate tumor biomarkers and treatment responses, with the objective of personalizing the therapies for patients with advanced HCC.

This paper discusses methods of predicting the BRDF of smooth surfaces from profile measurements of their surface finish. The conversion of optical profile data to the BRDF at the same wavelength is essentially independent of scattering models, while the conversion of mechanical measurements, and wavelength scaling in general, are model dependent. Procedures are illustrated for several surfaces, including two from the recent HeNe BRDF round robin, and results are compared with measured data. Reasonable agreement is found except for surfaces which involve significant scattering from isolated surface defects which are poorly sampled in the profile data

Squamous Cell Carcinoma Arising from Inverted Schneiderian Papilloma: A Case Report with Oral Involvement

Directory of Open Access Journals (Sweden)

Alexandre Simões Garcia

2014-01-01

Full Text Available Inverted Schneiderian papilloma is an uncommon benign tumor that presents tendency to recur and propensity to be associated with malignancy in approximately 10% of the cases. Some of these lesions are isolated in the maxillary sinus, and predominantly affect white males with mean age of 50 years. We report a case of squamous cell carcinoma arising from inverted Schneiderian papilloma in the maxillary sinus extending to the mouth. The patient was submitted to extraction of a maxillary molar tooth four months before the exacerbation of the symptoms of nasal airway obstruction and facial enlargement. Computed tomography scan revealed a sinonasal mass causing opacification of the right maxillary sinus with destruction of the lateral nasal wall and maxillary sinus floor. The patient was referred to an oncology center for treatment and died from tumor progression one year after the cancer was diagnosed. The intention of this report is to alert dentists to include the inverted Schneiderian papilloma, either associated with squamous cell carcinoma, or not, in the differential diagnosis of maxillary sinus tumors with aggressive behavior, which may extend to the oral cavity or involve roots of teeth.

There are conflicting reports about the renal involvement in Behcet's disease (BD). In this study we aimed to study the frequency and type of renal involvement in a group of patients with BD in Azerbaijan province that is one of the prevalent areas of BD in Iran. All cases of BD were prospectively followed between June 2004 and January 2007, and evaluated for renal dys-function (serum creatinine > 1.7 mg/dL), glomerular hematuria and proteinuria. Those patients with proteinuria > 500 mg/day and serum creatinine level > 2 mg/dL, underwent renal biopsy. From a total number of 100 patients, six patients (6%) had obvious renal involvements. Four patients had glomerular hematuria and proteinuria. Renal biopsy in two of them revealed measangial proliferative glumerulonephritis with IgA deposit in one of them and membranoproliferative glumerolonephritis in another one. Two remaining patients had serum creatinine > 2 mg/dL without any hematuria or proteinuria. Serologic study for viral agents and collagen vascular disease were negative in all patients with renal involvements. In conclusion, renal involvement in BD is not infrequent, although in most cases it is mild in nature and may be missed. (author)

Full Text Available Founded on practical rationality, this qualitative case study aimed to explore the teaching practice at university, focusing on teacher's reflections and competencies. To this end, teaching practices were described, analyzed, and interpreted. These interactions with students on a course in the pharmacy program, brought about situations involving dilemmas and learning opportunities for problem-solving and decision-making skills. Throughout the study, students were encouraged to use knowledge-in-action, reflection-in-action, and reflection-on-action, and these processes were also experienced by the teacher. Analysis of the records from classroom observation and the interviews with students and the teacher showed the fundamental role of such reflective processes, which led to attainment of the intended objectives. In this sense, the teacher's reflective practice was essential for supporting the application of each curricular component of the course.

Discordant lymphoma consisting of splenic mantle cell lymphoma and marginal zone lymphoma involving the bone marrow and peripheral blood: a case report

Directory of Open Access Journals (Sweden)

2011-09-01

Full Text Available Abstract Introduction Discordant lymphomas are rare entities characterized by the simultaneous presence of two distinct types of lymphomas in different anatomic sites. We describe a very rare case of simultaneous occurrence of splenic mantle cell lymphoma and marginal zone lymphoma involving the bone marrow and peripheral blood. Case presentation We report the case of a 60-year-old asymptomatic Caucasian woman in whom discordant lymphomas were discovered when a slight lymphocytosis and a conspicuous splenomegaly were observed. The different morphological, immunophenotypical and immunohistochemical features found in the different pathologic samples obtained from peripheral blood, bone marrow and spleen sections made it possible to differentiate two types of non-Hodgkin B-cell lymphomas: a mantle cell lymphoma infiltrating the spleen and a marginal zone lymphoma involving both the bone marrow and peripheral blood. Since a similar IgH gene rearrangement was found both in the bone marrow and in the spleen, the hypothesis of a common origin, followed by a different clonal selection of the neoplastic lymphocytes may be taken into consideration. Conclusion Our case emphasizes the usefulness of investigating simultaneous specimens from different anatomic sites from the same patient and the relevant diagnostic role of splenectomy.

Adenoid cystic carcinoma is among the most frequent malignancies in the salivary and lacrimal glands and has a grave prognosis characterized by frequent local recurrences, distant metastases, and tumor-related mortality. Conversely, adenoid cystic carcinoma of the breast is a rare type of triple-negative (estrogen and progesterone receptor, HER2) and basal-like carcinoma, which in contrast to other triple-negative and basal-like breast carcinomas has a very favorable prognosis. Irrespective of site, adenoid cystic carcinoma is characterized by gene fusions involving MYB, MYBL1, and NFIB, and the reason for the different clinical outcomes is unknown. In order to identify the molecular mechanisms underlying the discrepancy in clinical outcome, we characterized the phenotypic profiles, pattern of gene rearrangements, and global microRNA expression profiles of 64 salivary gland, 9 lacrimal gland, and 11 breast adenoid cystic carcinomas. All breast and lacrimal gland adenoid cystic carcinomas had triple-negative and basal-like phenotypes, while salivary gland tumors were indeterminate in 13% of cases. Aberrations in MYB and/or NFIB were found in the majority of cases in all three locations, whereas MYBL1 involvement was restricted to tumors in the salivary gland. Global microRNA expression profiling separated salivary and lacrimal gland adenoid cystic carcinoma from their respective normal glands but could not distinguish normal breast adenoid cystic carcinoma from normal breast tissue. Hierarchical clustering separated adenoid cystic carcinomas of salivary gland origin from those of the breast and placed lacrimal gland carcinomas in between these. Functional annotation of the microRNAs differentially expressed between salivary gland and breast adenoid cystic carcinoma showed these as regulating genes involved in metabolism, signal transduction, and genes involved in other cancers. In conclusion, microRNA dysregulation is the first class of molecules separating adenoid

2016-04-01

Full Text Available Background: This article presents the design of PROFILe, a study investigating which (biomedical and non-(biomedical patient characteristics should guide more tailored chronic care. Based on this insight, the project aims to develop and validate ‘patient profiles’ that can be used in practice to determine optimal treatment strategies for subgroups of chronically ill with similar healthcare needs and preferences. Methods/Design: PROFILe is a practice-based research comprising four phases. The project focuses on patients with type 2 diabetes. During the first study phase, patient profiles are drafted based on a systematic literature research, latent class growth modeling, and expert collaboration. In phase 2, the profiles are validated from a clinical, patient-related and statistical perspective. Phase 3 involves a discrete choice experiment to gain insight into the patient preferences that exist per profile. In phase 4, the results from all analyses are integrated and recommendations formulated on which patient characteristics should guide tailored chronic care. Discussion: PROFILe is an innovative study which uses a uniquely holistic approach to assess the healthcare needs and preferences of chronically ill. The patient profiles resulting from this project must be tested in practice to investigate the effects of tailored management on patient experience, population health and costs.

Churg-Strauss syndrome, recently renamed eosinophilic granulomatosis with polyangiitis (EGPA), is a rare form of systemic vasculitis, characterized by disseminated necrotizing vasculitis with extravascular granulomas occurring among patients with asthma and tissue eosinophilia. EGPA is classified as a small and medium-sized vessel vasculitis associated with antineutrophil cytoplasmic antibodies (ANCA) and the hypereosinophilic syndrome. Typical clinical features include asthma, sinusitis, transient pulmonary infiltrates and neuropathy. Blood eosinophils are often >1500/µl or more than 10% on the differential leukocyte count. Blood eosinophils should always be tested in unexplained cardiac disorders, and may normalize even after low doses of corticosteroids. ANCA are positive in 40-60% of cases, mainly anti-myeloperoxidase. Heart involvement occurs in approximately 15-60% of EGPA patients, especially those who are ANCA negative. Any cardiac structure can be involved, and patients present with myocarditis, heart failure, pericarditis, arrhythmia, coronary arteritis, valvulopathy, intracavitary cardiac thrombosis. Although cardiovascular involvement is usually an early manifestation, it can also occur later in the course of the disease. A significant proportion of patients with cardiac involvement is asymptomatic. In the absence of symptoms and major ECG abnormalities, cardiac involvement may be detected in nearly 40% of the patients. All patients with EGPA should be studied not only with a detailed history of cardiac symptoms and ECG, but also with echocardiography; if abnormalities are detected, a cardiac magnetic resonance study should be performed. Coronary angiography and endomyocardial biopsy should be reserved to selected cases. Heart involvement carries a poor prognosis and causes 50% of the deaths of these patients. It is often insidious and underestimated. Optimal therapy is therefore important and based on high-dose corticosteroids plus immunosuppressive

In the study we conducted we aimed at investigating the relation between personality profiles and risk diet behaviors in teenagers. This study was a case-control one and we applied 2 questionnaires (Freiburg Personality Inventory--FPI with 212 items) and CORT 2004 (items Q94-Q116 of diet behavior) on a sample of 2908 teenagers (51.5% girls and 48.5% boys). Cronbach's alpha index was 0.802 for FPI and 0.730 for items Q101-Q109 of CORT. Personality profiles were built by an Excel 2003 Program. Statistical analysis was realized with SPSS 16 program applying Chi square (chi2) and gamma (gamma) correlation. Personality features of teenagers with high and without risk diet behavior were analyzed. Results obtained: personality profiles and statistical results indicated the existence of a significant statistical difference of aggressiveness and domination between teenagers with high and no consumption of butter and/or lard (Q103) (chi2 = 6.872, Sig. 0.032 and chi2 = 6.922, Sig. 0.031 respectively), of juices from the market (Q106) (chi2 = 9.055, Sig. 0.011 and chi2 = 14.571, Sig. 0.001 respectively). Aggressiveness correlated with consumption of fried potatoes (Q109) (chi2 = 6.144, Sig. 0.046) too. Correlation gamma indicated direct proportional relations of aggressiveness with: Q103 (gamma = 0.215, Sig. 0.017), Q106 (gamma = 0.224, Sig. 0.004), Q109 (gamma = 0.242, Sig. 0.012); and of domination with: Q103 (gamma = 0.234, Sig. 0.008), Q106 (gamma = 0.073, Sig. 0.000). In conclusion, there is a direct proportional relation between consumption of: butter/lard, juices from the market and teenagers' aggressiveness, domination; and a similar relation between consumption of fried potatoes and aggressiveness.

Full Text Available Porokeratosis (PK is a group of cutaneous entities characterized by marginate scaling lesions, histologically showing a column of parakeratotic keratinocytes (cornoid lamella. Various forms are recognized such as porokeratosis of Mibelli (PM, linear porokeratosis, disseminated superficial actinic porokeratosis, punctate parakeratosis. PM should be treated because of the possibility of developing malignant epithelial tumors. We are presenting a 21 year old male patient suffering from PM on the back of the hands, foot, scrotum, oral mucosa and anal region. The histological biopsy specimens showed the characteristic features of porokeratosis. We destroyed the lesions by cryotherapy sessions. Here, we present a case of PM since it is rarely seen as multiple lesions with oral, anal and scrotal involvements altogether. (Turkderm 2008; 42: 97-9

Behcet's disease is a multisystem disease that involves the central nervous system up to half of cases. Presentation with neurologic symptoms occurs in 5 % of cases and cerebral venous thrombosis is one of its major manifestations. A feature not previously reported is progressive meningeal thickening with involvement of both optic nerves. We report a patient with cerebral venous thrombosis, meningeal thickening and contrast enhancement on MRI. This patient had two other unusual features: positive antineutrophil cytoplasmic antibodies and later development of central diabetes insipidus. (orig.)

To perform a systematic review of neurologic involvement in Systemic sclerosis (SSc) and Localized Scleroderma (LS), describing clinical features, neuroimaging, and treatment. We performed a literature search in PubMed using the following MeSH terms, scleroderma, systemic sclerosis, localized scleroderma, localized scleroderma "en coup de sabre", Parry-Romberg syndrome, cognitive impairment, memory, seizures, epilepsy, headache, depression, anxiety, mood disorders, Center for Epidemiologic Studies Depression (CES-D), SF-36, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Patient Health Questionnaire-9 (PHQ-9), neuropsychiatric, psychosis, neurologic involvement, neuropathy, peripheral nerves, cranial nerves, carpal tunnel syndrome, ulnar entrapment, tarsal tunnel syndrome, mononeuropathy, polyneuropathy, radiculopathy, myelopathy, autonomic nervous system, nervous system, electroencephalography (EEG), electromyography (EMG), magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA). Patients with other connective tissue disease knowingly responsible for nervous system involvement were excluded from the analyses. A total of 182 case reports/studies addressing SSc and 50 referring to LS were identified. SSc patients totalized 9506, while data on 224 LS patients were available. In LS, seizures (41.58%) and headache (18.81%) predominated. Nonetheless, descriptions of varied cranial nerve involvement and hemiparesis were made. Central nervous system involvement in SSc was characterized by headache (23.73%), seizures (13.56%) and cognitive impairment (8.47%). Depression and anxiety were frequently observed (73.15% and 23.95%, respectively). Myopathy (51.8%), trigeminal neuropathy (16.52%), peripheral sensorimotor polyneuropathy (14.25%), and carpal tunnel syndrome (6.56%) were the most frequent peripheral nervous system involvement in SSc. Autonomic neuropathy involving cardiovascular and gastrointestinal systems was regularly described

Patients with Down syndrome (DS) and acute lymphoblastic leukemia (ALL) have distinct clinical and biological features. Whereas most DS-ALL cases lack the sentinel cytogenetic lesions that guide risk assignment in childhood ALL, JAK2 mutations and CRLF2 overexpression are highly enriched. To further characterize the unique biology of DS-ALL, we performed genome-wide profiling of 58 DS-ALL and 68 non-Down syndrome (NDS) ALL cases by DNA copy number, loss of heterozygosity, gene expression, and methylation analyses. We report a novel deletion within the 6p22 histone gene cluster as significantly more frequent in DS-ALL, occurring in 11 DS (22%) and only two NDS cases (3.1%) (Fisher’s exact p = 0.002). Homozygous deletions yielded significantly lower histone expression levels, and were associated with higher methylation levels, distinct spatial localization of methylated promoters, and enrichment of highly methylated genes for specific pathways and transcription factor binding motifs. Gene expression profiling demonstrated heterogeneity of DS-ALL cases overall, with supervised analysis defining a 45-transcript signature associated with CRLF2 overexpression. Further characterization of pathways associated with histone deletions may identify opportunities for novel targeted interventions. PMID:21647151

Full Text Available Large vessel involvement is one of the hallmarks of Behcet’s disease (BD but its prevalence varies widely due to ethnic variation or environmental factors. The aim of this study is to find the characteristics of vasculo-Behcet (VB in Iran. In a cohort of 4769 patients with BD, those with vascular involvement were selected. Different manifestations of disease were compared with the remaining group of patients. A confidence interval at 95% (CI was calculated for each item. Vascular involvement was seen in 409 cases (8.6%; CI, 0.8. Venous involvement was seen in 396 cases, deep vein thrombosis in 294 (6.2%; CI, 0.7, superficial phlebitis in 108 (2.3%; CI, 0.4 and large vein thrombosis in 45 (0.9%; CI, 0.3. Arterial involvement was seen in 28 patients (25 aneurysms and 4 thromboses. Thirteen patients showed both arterial and venous involvement. The mean age of the patients with VB was slightly higher (P<0.03, but the disease duration was significantly longer (P<0.0003. VB was more common in men. As the presenting sign, ocular lesions were less frequent in VB (P<0.0006, while skin lesions were over 2 times more common in these cases (P<0.000001. VB was associated with a higher frequency of genital aphthosis, skin involvement, joint manifestations, epididymitis, CNS lesions and GI involvement. The juvenile form was less common in VB (P<0.03. High ESR was more frequent in VB (P=0.000002, but the frequency of false positive VDRL, pathergy phenomenon, HLA-B5 or HLA-B27 showed no significant difference between the two groups. In Iranian patients with BD, vascular involvement is not common and large vessel involvement is rare. It may be sex-related, and is more common in well-established disease with multiple organ involvement and longer disease duration.

Full Text Available Abstract Background Claudins are integral membrane proteins that are involved in forming cellular tight junctions. One member of the claudin family, claudin-3, has been shown to be overexpressed in breast, ovarian, and pancreatic cancer. Here we use immunohistochemistry to evaluate its expression in benign prostatic hyperplasia (BPH, prostatic intraepithelial neoplasia (PIN, normal tissue adjacent to prostatic adenocarcinoma (NAC, primary prostatic adenocarcinoma (PCa, and metastatic prostatic adenocarcinoma (Mets. Methods Tissue microarrays were immunohistochemically stained for claudin-3, with the staining intensities subsequently quantified and statistically analyzed using a one-way ANOVA with subsequent Tukey tests for multiple comparisons or a nonparametric equivalent. Fifty-three cases of NAC, 17 cases of BPH, 35 cases of PIN, 107 cases of PCa, and 55 cases of Mets were analyzed in the microarrays. Results PCa and Mets had the highest absolute staining for claudin-3. Both had significantly higher staining than BPH (p Conclusions To our knowledge, this represents one of the first studies comparing the immunohistochemical profiles of claudin-3 in PCa and NAC to specimens of PIN, BPH, and Mets. These findings provide further evidence that claudin-3 may serve as an important biomarker for prostate cancer, both primary and metastatic, but does not provide evidence that claudin-3 can be used to predict risk of metastasis.

This study examined profiles of nonresidential father engagement (i.e., support to the adolescent, contact frequency, remarriage, relocation, and interparental conflict) with their adolescent children (N = 156) 6 to 8 years following divorce and the prospective relation between these profiles and the psychosocial functioning of their offspring, 9 years later. Parental divorce occurred during late childhood to early adolescence; indicators of nonresidential father engagement were assessed during adolescence, and mental health problems and academic achievement of offspring were assessed 9 years later in young adulthood. Three profiles of father engagement were identified in our sample of mainly White, non-Hispanic divorced fathers: Moderate Involvement/Low Conflict, Low Involvement/Moderate Conflict, and High Involvement/High Conflict. Profiles differentially predicted offspring outcomes 9 years later when they were young adults, controlling for quality of the mother-adolescent relationship, mother's remarriage, mother's income, and gender, age, and offspring mental health problems in adolescence. Offspring of fathers characterized as Moderate Involvement/Low Conflict had the highest academic achievement and the lowest number of externalizing problems 9 years later compared to offspring whose fathers had profiles indicating either the highest or lowest levels of involvement but higher levels of conflict. Results indicate that greater paternal psychosocial support and more frequent father-adolescent contact do not outweigh the negative impact of interparental conflict on youth outcomes in the long term. Implications of findings for policy and intervention are discussed.

Capgras syndrome: a review of the neurophysiological correlates and presenting clinical features in cases involving physical violence.

Bourget, Dominique; Whitehurst, Laurie

2004-11-01

Acts of violence have been frequently reported in cases of Capgras syndrome (CS), a misidentification syndrome characterized by the delusional belief that imposters have replaced people familiar to the individual. CS has been observed in many neuropsychiatric and organic disorders, and neuroimaging studies indicate an association between CS and right hemisphere abnormalities. However, CS has received limited attention from a forensic psychiatric perspective. We propose that elucidating demographic and clinical features noted in cases of violence secondary to CS may highlight important factors in the progression of CS to violence. We review the neurophysiological correlates and clinical factors observed in CS and present characteristics of a series of cases that demonstrate the potential of CS patients for severe physical violence toward the misidentified person. For patients with CS involving assault, we present and discuss commonly reported demographic and clinical features that may contribute to an increased risk for violence. An understanding of the presenting clinical features of CS resulting in aggressive acts may assist clinicians to assess the potential for violence in these patients.

This paper reports a case of malignant lymphoma which was originated from the breast, followed by multiple involvement in the brain, and finally developed intraocular infiltration. These lesions disappeared by irradiation therapy. A 51 years old housewife was admitted to our hospital for the further evaluation and treatment of decreased bilateral visual acuity on May 1981. On May 1976, she noticed a solid tumor of the left breast, and total mastectomy disclosed malignant lymphoma (non-Hodgkin lymphoma, lymphocytic type). On August 1980, she developed diplopia and amnesia. CT scan revealed multiple involvements in brain and cobalt therapy resulted in good response. The ophthalmologic diagnosis was uveitis, but it was impossible to rule out the ophthalmic infiltration of malignant lymphoma and 60 Co irradiation (total 2,976 rad) to the bilateral eyes and systemic CHOP therapy were carried out. Consequently, her visual acuity recovered to 0.6, and she is now following ambulatory course. Although non-Hodgkin lymphomas have been reported to originate frequently from non lymphoid tissues, the breast as the primary site is rare and the intracerebral infiltration as an involvement of central nervous system is quite rare. Furthermore, malignant lymphoma of the eyes, especially intraocular involvement is infrequent in incidence. The diagnosis of uveitis due to malignant lymphoma is considered to be difficult because of lack in specific findings. (author)

Vanessa de Albuquerque Citero

Full Text Available ABSTRACT CONTEXT: An almost 50% prevalence of psychiatric disorders among cancer patients has prompted a series of studies on consultation-liaison psychiatry. Nonetheless, there are few reports on the epidemiological factors involving comorbidity between cancer and psychiatric disorders. OBJECTIVE: To evaluate the epidemiological profile of cancer inpatients referred to the consultation-liaison psychiatric service in an oncology hospital during its first year of activity. TYPE OF STUDY: Descriptive study. SETTING: Tertiary-care teaching hospital. PARTICIPANTS: 319 patients referred 412 times to the consultation-liaison psychiatry service. PROCEDURES: From August 97 to July 98, an appraisal was made of data on all admissions registered at the Hospital do Câncer, and also all referrals registered at the consultation-liaison psychiatry service. MAIN MEASUREMENTS: The demographics and patients' clinical data, the type and flow of the request, and the evaluation conducted by the service were analyzed and comparisons with the hospital data were made. The distribution of the number of referrals was used to construct a profile of patients who had repeatedly used the service. RESULTS: Psychiatric diagnoses were found in 59% of the cases. Forty-three percent of these required medication, 18.3% needed psychotherapy, 22.1% family intervention and 20.5% guidance from the staff. Over 22.8% of the consultations were reevaluations, mainly involving younger male patients with worst prognoses. These patients required lengthier and more elaborate intervention, and had higher prevalence of depressive and behavioral disorders. CONCLUSION: A younger and mainly male population of non-surgical oncological cases was referred to the consultation-liaison psychiatric service during its first year of activity. The psychiatric disorder prevalence was higher than expected, and consisted predominantly of mood disorders. We detected a priority group, namely the reevaluated

Evaluation of mixed-source, low-template DNA profiles in forensic science.

Balding, David J

2013-07-23

Enhancements in sensitivity now allow DNA profiles to be obtained from only tens of picograms of DNA, corresponding to a few cells, even for samples subject to degradation from environmental exposure. However, low-template DNA (LTDNA) profiles are subject to stochastic effects, such as "dropout" and "dropin" of alleles, and highly variable stutter peak heights. Although the sensitivity of the newly developed methods is highly appealing to crime investigators, courts are concerned about the reliability of the underlying science. High-profile cases relying on LTDNA evidence have collapsed amid controversy, including the case of Hoey in the United Kingdom and the case of Knox and Sollecito in Italy. I argue that rather than the reliability of the science, courts and commentators should focus on the validity of the statistical methods of evaluation of the evidence. Even noisy DNA evidence can be more powerful than many traditional types of evidence, and it can be helpful to a court as long as its strength is not overstated. There have been serious shortcomings in statistical methods for the evaluation of LTDNA profile evidence, however. Here, I propose a method that allows for multiple replicates with different rates of dropout, sporadic dropins, different amounts of DNA from different contributors, relatedness of suspected and alternate contributors, "uncertain" allele designations, and degradation. R code implementing the method is open source, facilitating wide scrutiny. I illustrate its good performance using real cases and simulated crime scene profiles.

This article describes the treatment of a young adult male with a concave profile, skeletal class III malocclusion because of a prognathic mandible and proclined upper incisors. The therapy included stages: 1. Pre-surgical orthodontics involving leveling and aligning of upper and lower arches, protraction of lower molars and retraction of upper incisors; 2. Surgical phase involving BSSO with mandibular setback and 3. Post-surgical orthodontics for finishing and detailing. The treatment lasted 23 months and improved facial esthetics significantly The treatment resulted in a functional occlusion with a lack of lateral cuspid guidance that could be accepted considering the difficulty of the case. Over jet and overbite are within norms.

Full Text Available Purpose of the study: The purpose of this study was to report clinical features, neuroimaging, and visual outcome in pediatric optic neuritis (ON in Indian population. Materials and Methods: This is a retrospective study of children up to the age of 16 years, diagnosed with ON, that presented at pediatric and neuroophthalmology clinic of a tertiary eye care center, in South India, within the period of 2010–2015. Results: We identified 62 eyes of 40 children diagnosed as ON within the study period. The mean age was 11.15 ± 3.24 years (1–15 years with mean follow-up of 13 months. In this series, there was female preponderance (67%. Mean logarithm of the minimum angle of resolution visual acuity at presentation was 1.14 ± 0.93, which after treatment recovered to 0.10 ± 0.26 at final visit (P < 0.001. Involvement was bilateral in 22 children (55% and recurrent in 3 eyes of 3 children. Preceding febrile illness was reported in seven cases (18%. Four (10% cases were diagnosed as multiple sclerosis (MS, one with neuromyelitis optica , and one with acute disseminated encephalomyelitis. One case was associated with tuberculous meningitis, 1 with septicemia, and 1 with bilateral maxillary sinusitis. Neuroimaging studies of optic nerve in 14 children demonstrated isolated optic nerve enhancement. Magnetic resonance imaging brain revealed white matter T2 hyperintense lesions separate from optic nerve in ten cases, of which four cases were diagnosed as MS. Conclusions: Bilateral presentation was common, association with MS was low. Papillitis was more frequent than retrobulbar neuritis and prognosis was good in pediatric ON in Indian population.

Full Text Available Background: Suicides, attempted suicides and different form of suicidal behaviors are on the rise in most part of the world. It is generally assumed that official suicidal rate are underestimated from the true rate by 20-100 % due to prevailing socio-cultural issues, religious attitude, stigma attached, and legal process involved. Attempted suicides occur 8-20 times more frequently than complete suicide. Statistics on attempted suicide or deliberate self harm are not usually available officially. Materials and Methods: All the cases of attempted suicide who were admitted and referred for psychiatric evaluation and management to a rural medical college of central India during a period of one Year (April 13-March-14, following initial recovery they were evaluated on a semi-structured performa on socio demographic profile, mode of attempt and reason for attempt. Data collected was analyzed using suitable statistical methods. Results: Total 68 cases were evaluated during the study period. 43% of the cases were involved in farming. Among 85% of the study population pesticide consumption was the common mode of attempt, which is easily available among the agrarian community of rural India. Interpersonal conflict in the family due to indebtedness, financial loss due to crop failure was the commonest reason for attempt. Conclusion: Though there is reduced reporting in the incidents of suicide cases in media from this region, still quite a number of people attempt suicide due to financial constraint from crop failure, ongoing indebtedness, and poor socioeconomic condition culminating into poor mental health among the rural agrarian community of central Maharashtra.

To determine the profiles of highly frequent users of primary care services and the associations of these profiles with depressive anxiety disorders in Cali, Colombia. A case-control study, high-frequency cases were defined as those involving patients with a percentile >75 with regard to the frequency of spontaneous use of outpatient facilities in the last 12 months; controls were defined as those with a percentile depression and anxiety on frequent attendance was determined via logistic regression. Among the 780 participating patients, differences in the profiles among frequent users and controls were related to predisposing factors such as sex, age, and education, capacity factors such as the time required to visit the institution and the means of transport used, and need factors such as health perceptions, social support, family function, and the presence of anxiety or depressive disorders. A depression or anxiety disorder was found to associate positively with frequent attendance (adjusted odds ratio [aOR]: 1.99, 95% confidence interval [CI]: 1.19-3.31) and a referral system (aOR: 1.61, 95% CI: 1.01-2.76), but negatively with mild or no family dysfunction (aOR: 0.79; 95% CI: 0.48-0.88) after adjusting for age, sex, ethnicity, and health service-providing institutions. The profiles of high-frequency patients differ from control patients with respect to factors related to capacity, need, and willingness; in particular, the latter were independently associated with frequent attendance. Notably, the presence of an anxious or depressive disorder doubled the risk of highfrequency attendance at a primary care facility.

Criminal profiling as expert witness evidence: The implications of the profiler validity research.

Science.gov (United States)

Kocsis, Richard N; Palermo, George B

The use and development of the investigative tool colloquially known as criminal profiling has steadily increased over the past five decades throughout the world. Coupled with this growth has been a diversification in the suggested range of applications for this technique. Possibly the most notable of these has been the attempted transition of the technique from a tool intended to assist police investigations into a form of expert witness evidence admissible in legal proceedings. Whilst case law in various jurisdictions has considered with mutual disinclination the evidentiary admissibility of criminal profiling, a disjunction has evolved between these judicial examinations and the scientifically vetted research testing the accuracy (i.e., validity) of the technique. This article offers an analysis of the research directly testing the validity of the criminal profiling technique and the extant legal principles considering its evidentiary admissibility. This analysis reveals that research findings concerning the validity of criminal profiling are surprisingly compatible with the extant legal principles. The overall conclusion is that a discrete form of crime behavioural analysis is supported by the profiler validity research and could be regarded as potentially admissible expert witness evidence. Finally, a number of theoretical connections are also identified concerning the skills and qualifications of individuals who may feasibly provide such expert testimony. Copyright © 2016 Elsevier Ltd.

Transcript Profiling Identifies NAC-Domain Genes Involved in Regulating Wall Ingrowth Deposition in Phloem Parenchyma Transfer Cells of Arabidopsis thaliana

Directory of Open Access Journals (Sweden)

Yuzhou Wu

2018-03-01

Full Text Available Transfer cells (TCs play important roles in facilitating enhanced rates of nutrient transport at key apoplasmic/symplasmic junctions along the nutrient acquisition and transport pathways in plants. TCs achieve this capacity by developing elaborate wall ingrowth networks which serve to increase plasma membrane surface area thus increasing the cell's surface area-to-volume ratio to achieve increased flux of nutrients across the plasma membrane. Phloem parenchyma (PP cells of Arabidopsis leaf veins trans-differentiate to become PP TCs which likely function in a two-step phloem loading mechanism by facilitating unloading of photoassimilates into the apoplasm for subsequent energy-dependent uptake into the sieve element/companion cell (SE/CC complex. We are using PP TCs in Arabidopsis as a genetic model to identify transcription factors involved in coordinating deposition of the wall ingrowth network. Confocal imaging of pseudo-Schiff propidium iodide-stained tissue revealed different profiles of temporal development of wall ingrowth deposition across maturing cotyledons and juvenile leaves, and a basipetal gradient of deposition across mature adult leaves. RNA-Seq analysis was undertaken to identify differentially expressed genes common to these three different profiles of wall ingrowth deposition. This analysis identified 68 transcription factors up-regulated two-fold or more in at least two of the three experimental comparisons, with six of these transcription factors belonging to Clade III of the NAC-domain family. Phenotypic analysis of these NAC genes using insertional mutants revealed significant reductions in levels of wall ingrowth deposition, particularly in a double mutant of NAC056 and NAC018, as well as compromised sucrose-dependent root growth, indicating impaired capacity for phloem loading. Collectively, these results support the proposition that Clade III members of the NAC-domain family in Arabidopsis play important roles in

To identify the contextual factors that influence individual patient involvement during colorectal cancer surgical follow-up consultations. The healthcare system is subject to the requirement and expectation of greater involvement of patients and relatives. Increased patient involvement requires the development and implementation of new communication initiatives. Research shows that it is also necessary to consider the contextual circumstances surrounding patient involvement in specific situations. Case study of a single Danish outpatient clinic, which allows the issues and circumstances involved in an everyday situation to be captured. 12 nonparticipative observations of outpatient visits and, subsequently, seven in-depth patient interviews. Content analysis based on a dialogical, interactive framework, which underpinned the identification of current contextual factors. The results showed five contextual factors that seemed to have an impact on patient involvement. The first, 'Two dimensions of patient involvement: treatment-oriented and person-oriented' highlighted a dual interpretation of patient involvement in the consultation situation. The two dimensions seemed to be influenced by four additional factors: 'Doctors leading the agenda', 'Traditional health professional roles', 'Unclear responsibilities' and 'Guidance primarily focused on treatment'. The results showed how patient involvement in clinical practice could be understood as a two-way movement, in which patients are invited to participate in clinical practice, while health professionals are invited to participate in the patients' lives. The movement will change from situation to situation and is influenced by several contextual factors. The results can help doctors and nurses to navigate using a goal-oriented approach towards patient involvement. The study makes visible the need for research-based development of the independent role of the nursing profession in cancer care follow-up, with a view to

In order to determine the value of CT in detecting lymphomatous involvement of the liver, 57 autopsied cases (48 cases of non-Hodgkin lymphoma and 9 of Hodgkin's disease) were analyzed in detail. Additionally, 90 recent cases of abdominal CT with liver study in the initial staging were reviewed and 6 cases in which the liver had been examined within 2 weeks before autopsy were compared for macroscopic and pathologic findings. The following results were obtained. 1) Autopsy findings in 57 cases of malignant lymphoma. (1) Hepatic involvement was demonstrated in 56% of the patients with non-Hodgkin lymphoma and in 67% of those with Hodgkin's disease. (2) Of these patients with hepatic involvement, intrahepatic nodular lesions over 1.0cm in diameter were macroscopically identified in 22% of the cases of non-Hodgkin lymphoma and 33% of those with Hodgkin's disease. (3) Lymphomatous involvements were seen in many organs in the cases of hepatic involvement. 2) CT examinations of 90 cases for the initial staging showed no significant abnormality in the liver or spleen. 3) Of the 6 cases in which the liver was examined by CT within about 2 weeks before autopsy, lymphomatous involvemet was pathologically diagnosed in 5. Of these, only one having multiple nodules larger than the tip of a thumb was correctly diagnosed by CT. 4) Hepatic involvement of lymphoma was thought to be the end stage, and minimal or early disease was detected in the region of Glisson's capsule. The above findings indicate that early hepatic involvement is not likely to be detected by CT at the present time. (author)

Full Text Available Nonalcoholic fatty liver disease (NAFLD is considered the most common liver disease in the world. Dietary habits have a significant impact on the biological and physical profile of patients and increase the risk of NAFLD. The overall pattern of diet intake is more associated with health outcomes than nutrients. The aim of this study was to evaluate the nutritional profile and the dietary patterns of Lebanese NAFLD patients and compare it with controls. During this study; 112 NAFLD Lebanese adult patients (55 men and 57 women; and 110 controls (44 men and 66 women were recruited. Dietary intake was evaluated by two 24-h recalls and a semi-quantitative 90-item food frequency questionnaire. Dietary patterns were determined by factor analysis. Results from the study demonstrated that 40% of cases belonged to the high fruit group as compared to 30% following a high meat; fast food dietary pattern. Both groups increased the odds of NAFLD by four-fold (p < 0.05. The traditional diet decreases the odds by 33% after adjustment with the covariables. The high fruit diet group was, as with the high meat, fast food dietary pattern, the main potential risk factor for NAFLD in Lebanese patients.

Full Text Available Abstract Background Carcinoma of the gallbladder (GBC clinically mimics benign gallbladder diseases and often escapes detection until advanced stage. Despite the frequency of cholecystectomy, diagnosis of GBC remains problematic in many situations. We sought to identify pathologic features that contribute to the difficulty in recognition of GBC. Methods We identified 23 patients (ranged from 45 to 86 years, male to female ratio 1:4.5 with carcinoma involving the gallbladder referred to an academic medical center over a period of 10 years for study. This includes 10 cases of primary GBC, 6 cases of metastatic tumor to gallbladder, 6 cases of directly invasive adenocarcinoma arising elsewhere in the biliary tree, and one case of unidentified origin adenocarcinoma.

Critchfield, Kenneth L; Benjamin, Lorna Smith; Levenick, Kathleen

2015-08-01

Interpersonal Reconstructive Therapy (IRT) case formulations describe psychosocial mechanisms of affective and personality pathology in ways that enhance the effectiveness of psychotherapy for individuals. With a valid and reliable IRT case formulation, a clinician is in a better position to draw upon effective techniques to maximize treatment effects. The case formulation and treatment models for IRT were described in depth along with the IRT treatment model by Benjamin (2003/2006). Data in this report from 93 adult inpatients with complex and comorbid presentations suggest that the case formulation is highly reliable and unique to individuals, and that symptoms reflect current interpersonal stresses linked to early interactions involving forms of hostility in relation with attachment figures and corresponding to three basic patterns in adulthood: identification (be like him or her), recapitulation (act as you did with him or her), and introjection (treat yourself as you were treated).

Erdheim Chester disease is a rare non-Langerhans cell histiocytosis which may involve multiple organs including bone, soft tissue, lungs, cardiovascular system, kidneys (retroperitoneum), skin, and central nervous system. Bone involvement is most common followed by other organs. This case report describes a 58-year-old man who presented with progressive renal dysfunction presumed due to obstruction. The patient failed multiple urinary tract interventions, and clinical course was complicated by recurrent low-grade fevers, and bilateral knee pain. Advanced imaging and histopathological features on bone biopsy were consistent with Erdheim Chester disease. Molecular studies of tissue showed BRAF V600 mutation. This patient was treated with Zelboraf (vemurafenib) BRAF inhibitor with subsequent improvement in renal and pleural dysfunction as well as decreased histiocytic soft tissue masses on CT. (orig.)

Multiple Cranial Nerve Involvement In Cryptococcal Meningitis

Directory of Open Access Journals (Sweden)

Mahadevan A

2000-01-01

Full Text Available Cryptococcal meningitis is an uncommon cause of multiple cranial nerve palsies. This case report illustrates one such case of cryptococcal meningitis clinically manifesting with extensive cranial nerve involvement in an HIV seronegative individual. Histology revealed infiltration of the cranial nerves by cryptococci causing axonal disruption with secondary demyelination in the absence of any evidence of inflammation or vasculitis. We believe that axonal damage underlies the pathogenesis of cranial nerve involvement in cryptococcal meningitis.

Almost all conferences for plastic and maxillofacial surgery discuss reports on several methods of orthognathic surgery, planning, success results, and complications of the different procedures carried out to correct patient's soft and hard tissues frontal profiles and occlusal discrepancies. Various principles are involved in the diagnosis and treatment of facial deformities. However, the most important consideration, after all, is the final accepted aesthetic and functional requirements and stability of the moved segments. The objective of this paper is to give the basic principles of treatment planning for correcting facial discrepancies, surgical approach to different cases, and the methods to increase stability of the moved segments. Six cases are included to illustrate the different aspects of treatment planning, surgical management, and stabilization methods. (author)

Colon cancer can arise from the mucosa in a colonic diverticulum. Although colon diverticulum is a common disease, few cases have been previously reported on colon cancer associated with a diverticulum. We report a rare case of sigmoid colon cancer arising in a diverticulum with involvement of the urinary bladder, which presented characteristic radiographic images. A 73-year-old man was admitted to our hospital for macroscopic hematuria. Computed tomography and magnetic resonance imaging revealed a sigmoid colon tumor that protruded into the urinary bladder lumen. The radiographs showed a tumor with a characteristic dumbbell-shaped appearance. Colonoscopy showed a type 1 cancer and multiple diverticula in the sigmoid colon. A diagnosis of sigmoid colon cancer with involvement of the urinary bladder was made based on the pathological findings of the biopsied specimens. We performed sigmoidectomy and total resection of the urinary bladder with colostomy and urinary tract diversion. Histopathological findings showed the presence of a colovesical fistula due to extramurally growing colon cancer. Around the colon cancer, the normal colon mucosa was depressed sharply with lack of the muscular layer, suggesting that the colon cancer was arising from a colon diverticulum. The present case is the first report of sigmoid colon cancer arising in a diverticulum with involvement of the urinary bladder. Due to an accurate preoperative radiological diagnosis, we were able to successfully perform a curative resection for sigmoid colon cancer arising in a diverticulum with involvement of the urinary bladder.

Size-dependent mortality rate profiles.

Science.gov (United States)

Roa-Ureta, Ruben H

2016-08-07

Knowledge of mortality rates is crucial to the understanding of population dynamics in populations of free-living fish and invertebrates in marine and freshwater environments, and consequently to sustainable resource management. There is a well developed theory of population dynamics based on age distributions that allow direct estimation of mortality rates. However, for most cases the aging of individuals is difficult or age distributions are not available for other reasons. The body size distribution is a widely available alternative although the theory underlying the formation of its shape is more complicated than in the case of age distributions. A solid theory of the time evolution of a population structured by any physiological variable has been developed in 1960s and 1970s by adapting the Hamilton-Jacobi formulation of classical mechanics, and equations to estimate the body size-distributed mortality profile have been derived for simple cases. Here I extend those results with regards to the size-distributed mortality profile to complex cases of non-stationary populations, individuals growing according to a generalised growth model and seasonally patterned recruitment pulses. I apply resulting methods to two cases in the marine environment, a benthic crustacean population that was growing during the period of observation and whose individuals grow with negative acceleration, and a sea urchin coastal population that is undergoing a stable cycle of two equilibrium points in population size whose individuals grow with varying acceleration that switches sign along the size range. The extension is very general and substantially widens the applicability of the theory. Copyright © 2016 Elsevier Ltd. All rights reserved.

Offset-electrode profile acquisition strategy for electrical resistivity tomography

Science.gov (United States)

Robbins, Austin R.; Plattner, Alain

2018-04-01

We present an electrode layout strategy that allows electrical resistivity profiles to image the third dimension close to the profile plane. This "offset-electrode profile" approach involves laterally displacing electrodes away from the profile line in an alternating fashion and then inverting the resulting data using three-dimensional electrical resistivity tomography software. In our synthetic and field surveys, the offset-electrode method succeeds in revealing three-dimensional structures in the vicinity of the profile plane, which we could not achieve using three-dimensional inversions of linear profiles. We confirm and explain the limits of linear electrode profiles through a discussion of the three-dimensional sensitivity patterns: For a homogeneous starting model together with a linear electrode layout, all sensitivities remain symmetric with respect to the profile plane through each inversion step. This limitation can be overcome with offset-electrode layouts by breaking the symmetry pattern among the sensitivities. Thanks to freely available powerful three-dimensional resistivity tomography software and cheap modern computing power, the requirement for full three-dimensional calculations does not create a significant burden and renders the offset-electrode approach a cost-effective method. By offsetting the electrodes in an alternating pattern, as opposed to laying the profile out in a U-shape, we minimize shortening the profile length.

Fashion trend in the world changed extremely fast. Fashion has become the one of people’s lifestyle in the world. Fashion week events in several areas can be a measurement of fahion trend nowadays. There was a fashion week event in Indonesia called Jakarta Fashion Week (JFW) aims to show fashion trend to people who want to improve their fashion style. People will join some events if the event has involvement to them, hence they will come to that event again and again. Annually and continuously event is really important to create loyalty among people who are involved in it, in order to increase positive development towards the organizer in organizing the next event. Saving a huge amount from the marketing budget, and creating a higher quality event. This study aims to know the effect of 5 brand personality dimension to event involvement and loyalty in Jakarta Fashion Week (JFW). This study use quantitative confirmative method with Structural Equation Model (SEM) analysis technique. The sample of this study is 150 respondents who became a participant of Jakarta Fashion Week 2017. Result show that there was significant effect of 5 brand personality dimension to 3 dimension of event involvement and loyalty. Meanwhile, there was one dimension of event involvement called personal self-expression that has not effect to loyalty.

This study examined profiles of non-residential father engagement (i.e., support to the adolescent, contact frequency, remarriage, relocation, and interparental conflict) with their adolescent children (N = 156) six to eight years following divorce and the prospective relation between these profiles and the psychosocial functioning of their offspring, nine years later. Parental divorce occurred during late childhood to early adolescence; indicators of non-residential father engagement were assessed during adolescence, and mental health problems and academic achievement of offspring were assessed nine years later in young adulthood. Three profiles of father engagement were identified in our sample of mainly White, non-Hispanic divorced fathers: Moderate Involvement/Low Conflict, Low Involvement/Moderate Conflict, and High Involvement/High Conflict. Profiles differentially predicted offspring outcomes nine years later when they were young adults, controlling for quality of the mother-adolescent relationship, mother’s remarriage, mother’s income, and gender, age and offspring mental health problems in adolescence. Offspring of fathers characterized as Moderate Involvement/Low Conflict had the highest academic achievement and the lowest number of externalizing problems nine years later compared to offspring whose fathers had profiles indicating either the highest or lowest levels of involvement but higher levels of conflict. Results indicate that greater paternal psychosocial support and more frequent father-adolescent contact do not outweigh the negative impact of interparental conflict on youth outcomes in the long-term. Implications of findings for policy and intervention are discussed. PMID:24484456

Renal dysfunction is increasingly recognized as a potential clinical feature of mitochondrial cytopathies such as mitochondrial encephalomyopathy, lacticacidosis and stroke-like episodes (MELAS) syndrome. Five cases of MELAS syndrome with renal involvement from 4 unrelated families are presented in this case series. Three of the 5 patients had a history of maternally-inherited diabetes and/or deafness. Focal and segmental glomerulosclerosis and arteriolar hyaline thickening were the most striking findings on renal biopsy. In addition to clinical presentation with the typical symptoms of MELAS syndrome, genetic testing in these patients identified the A3243G point mutation in the tRNALeu gene of the mitochondrial DNA (mtDNA). The diagnosis of MELAS syndrome was thus considered to be unequivocal. The incidence of kidney disease in MELAS syndrome may be underestimated although a study is required to investigate this hypothesis. As the A3243G mtDNA mutation leads to a progressive adult-onset form of focal segmental glomerulosclerosis (FSGS), screening for the MELAS A3243G mtDNA mutation should therefore be performed especially in patients with maternally-inherited diabetes or hearing loss presenting with FSGS.

Analytical reports from the clinical laboratory are essential to guide clinicians about what lipid profile values should be considered altered and, therefore, require intervention. Unfortunately, there is a great heterogeneity in the lipid values reported as "normal, desirable, recommended or referenced" by clinical laboratories. This can difficult clinical decisions and be a barrier to achieve the therapeutic goals for cardiovascular prevention. A recent international recommendation has added a new heterogeneity factor for the interpretation of lipid profile, such as the possibility of measuring it without previous fasting. All this justifies the need to develop a document that adapts the existing knowledge to the clinical practice of our health system. In this regard, professionals from different scientific societies involved in the measurement and use of lipid profile data have developed this document to establish recommendations that facilitate their homogenization.

MELAS syndrome -myopathy, encephalopathy, lactic acidosis and stroke-like episodes- is a maternally-inherited mitochondrial cytopathy related to several mitochondrial DNA mutations, with the A3243G mutation in tRNA Leu gene being the most frequent of them. Apart from its typical symptomatology, patients usually exhibit a maternally-inherited history of neurosensory deafness and insulin-dependent type 2 diabetes mellitus (T2DM). Recent studies have shown that few patients carrying a A3243G mutation also suffer from renal dysfunction, usually in form of focal segmental glomerulosclerosis (FSGS). In this study we examine kidney involvement in 2 unrelated patients with a A3243G mutation by genetic testing. Both have a maternally-inherited neurosensory deafness and insulin-dependent T2DM. A renal biopsy was performed in both patients. One patient developed nephrotic proteinuria and renal insufficiency, with FSGS findings being observed in the kidney biopsy, whereas the other suffered from mild proteinuria and renal insufficiency, with non-specific glomerular changes. The presence of FSGS or other kidney involvement accompanied by hereditary neurosensory deafness and T2DM could be suggestive of a A3243G tRNA Leu mutation and should prompt a genetic testing and an evaluation of potential extrarenal involvement.

2012-06-01

Full Text Available Purpose: In a multitude of studies, it is verified that the generation of positive attitudes for employees such as job satisfaction or job involvement, have a positive influence on productivity levels of companies. The current investigation focus on the identification of employee-profile -who is emotionally involved with their work activity- through the use of a set of individual, job related and attitudinal factors.Design/methodology: A review of the literature about the main factors that affect the job involvement particularly on its emotional dimension has been completed. For its measurement at the empirical level, various items related to psychological well being of employees included in the IV European Working Conditions Survey-2010 are used. Moreover, those items are identified in Job Involvement Questionnaire (Lodahl & Kejner, 1965. Since then, an empirical and multidimensional study is carried out by applying a logistic regression model on the sample of 11,149 employees obtained with European survey cited previously.Findings: The logistic regression model identifies the factors, which are directly related to emotional involvement at the workplace. Ultimately, is raised a definitive model that define the European employee-profile -who is emotionally involved at the workplace-: a rather aged person who has been working at his/her present place of employment for several years in a medium-sized company where possibly there exist a good working relationship between workers and their superiors –social support-. These employees are “white-collar” workers, have career advancement opportunities in the organizational hierarchy. They perform variety, flexible and complex tasks, which leads to satisfaction in terms of pay and working conditions.Research limitations/implications: Emotional involvement has been measured through self-awareness and, therefore, the corresponding bias in the key variable must be assumed. In addition, the casual

Sameer Saleem, Sundas Younas, Kamran Qayyum

2015-07-01

Full Text Available Rosai-Dorfman disease (RDD, which is also called as sinus histiocytosis with massive lymphadenopathy (SHML, is a rare histiocytic disorder which occurs due to the over-production of non Langerhans sinus histiocytes. It is a nonmalignant disorder that most frequently affects children and young adults and typically presents with fever, night sweats, nonpainful cervical lymphadenopathy, leukocytosis and an elevated ESR. Extranodal involvement may also occur, thus a variety of organs in the body can be affected. Although some viral etiology has been implicated, the disease generally is considered to have an unknown cause. RDD can often be misdiagnosed as lymphoma, leukemia or tuberculosis, so it is imperative to distinguish it from these conditions as well as other forms of histiocytosis because of difference in the modes of treatment. Diagnosis of Rosai-Dorfman disease is based on biopsy of affected tissue. Biopsy showing the presence of emperipolesis, or the engulfment of lymphocytes and other immune cells by histiocytes that express S-100 antigen is diagnostic of Rosai-Dorfman disease. Once diagnosed, further workup including imaging studies are undertaken in order to determine the extent of the disease. In majority of cases, the disease resolves on its own however, treatments including corticosteroids, chemotherapy, surgical treatment or radiotherapy are carried out in severe or persistent disease or when organ function is at stake (e.g. breathing obstruction, kidney failure, visual problems. The case we report is that of a 16 year old girl who presented with a 6 month history of gradual onset drooping of left upper eyelid with mild proptosis of the left eye alongwith mild drooping of right upper eyelid, low grade fever, night sweats and cervical lymphadenopathy. Blood workup showed increased ESR, CT scan of orbits showed superior orbital masses and diagnostic biopsy revealed Rosai-Dorfman disease.

Highlights: • Minimum Associated Subtask (MAS) and Minimum Effective Component (MEC) are presented in Mission Profile analysis. • Via applying MAS and MEC, Mission Profile plays a more important role in complex system reliability analysis. • Mission Profile has already been used in the reliability analysis of localized Chinese 1000 MW NPP Primary Pump. - Abstract: The traditional Mission Profile analysis did not clarify the accurate concept of minimum subtask and component. However, there are several components, which could be the influencing key element of the system reliability; and there are several subtasks, which could be used as a basic and crucial mission. In this paper, traditional method of Mission Profile has been extended by incorporating two new ideas: Minimum Associated Subtask (MAS) and Minimum Effective Component (MEC). This method of Mission Profile modeling is derived from Chinese 1000 MW NPP Primary Pump localization. A case study on Primary Pump reliability has been presented; then, MAS and MEC have been existed as vital elements in its lifecycle profile construction. By means of MAS and MEC, Mission Profile plays a more important role on complex system (Primary Pump) reliability analysis.

Molecular profiling--a tool for addressing emerging gaps in the comparative risk assessment of GMOs.

Science.gov (United States)

Heinemann, Jack A; Kurenbach, Brigitta; Quist, David

2011-10-01

Assessing the risks of genetically modified organisms (GMOs) is required by both international agreement and domestic legislation. Many view the use of the "omics" tools for profiling classes of molecules as useful in risk assessment, but no consensus has formed on the need or value of these techniques for assessing the risks of all GMOs. In this and many other cases, experts support case-by-case use of molecular profiling techniques for risk assessment. We review the latest research on the applicability and usefulness of molecular profiling techniques for GMO risk assessment. As more and more kinds of GMOs and traits are developed, broader use of molecular profiling in a risk assessment may be required to supplement the comparative approach to risk assessment. The literature-based discussions on the use of profiling appear to have settled on two findings: 1. profiling techniques are reliable and relevant, at least no less so than other techniques used in risk assessment; and 2. although not required routinely, regulators should be aware of when they are needed. The dismissal of routine molecular profiling may be confusing to regulators who then lack guidance on when molecular profiling might be worthwhile. Molecular profiling is an important way to increase confidence in risk assessments if the profiles are properly designed to address relevant risks and are applied at the correct stage of the assessment.

Full Text Available Abstract Background Breast cancer may be classified into luminal A, luminal B, HER2+/ER-, basal-like and normal-like subtypes based on gene expression profiling or immunohistochemical (IHC characteristics. The aim of our study is to show the molecular profile characteristic of breast cancer in the North African population of Morocco. This work showed preliminary results and correlations with clinicopathological and histological parameters. Three hundred and ninety primary breast carcinomas tumor tissues were immunostained for ER, PR, HER2, CK5/6, CK8/18 and Ki67 using paraffin tissue. Methods We reviewed 390 cases of breast cancer diagnosed on January 2008 to December 2011 at the Department of pathology, Hassan II teaching hospital, Fez, Morocco. Age, size tumor, metastatic profile, node involvement profile, histological type and immunohistochemical profile were studied. Results The average age was 46 years; our patients were diagnosed late with a high average tumor size. Luminal B subtype was more prevalent (41.8%, followed by luminal A (30.5%, basal-like (13, 6%, Her2-overexpressing (9, 2%, and unclassified subtype (4.9%. Conclusion This study showed that molecular classification and biological profile may be different according to geographical distribution, to encourage further studies to know the genomic profile of tumors and the environment.

The occurrence and development of fogs result from the non-linear interaction of competing radiative, thermodynamic, microphysical and dynamical processes and the forecasting of their life cycle still remains a challenging issue. Several field campaigns have been carried out at the SIRTA observatory in the Paris suburb area (France). These experiments have shown that fog events exhibit large differences of the microphysical properties and various evolutions during their life cycle. To better understand relationships between the different processes and to validate numerical simulations it is necessary however to document the vertical profile of the fog microphysics. A CDP (Cloud Droplet Spectrometer) from DMT (Droplet Measurement Technology, Boulder, CO) has been modified to allow measurements of the droplet size distribution in fog layers with a tethered balloon. This instrumental set-up has been used during a field campaign during the winter 2013-214 in the Landes area in the South West of France. To validate the vertical profiles provided by the modified CDP, a mast was equipped with microphysical instruments at 2 altitude levels with an another CDP at 24 m and a Fog Monitor FM100 at 42 m. The instrumental set-up deployed during this campaign is presented. Data collected during a fog event that occurred during the night of 5-6 March 2014 are analysed. We show that microphysical properties such as droplet number concentration, LWC and mean droplet size, exhibit different time evolution during the fog life cycle depending on the altitude level. Droplet size distribution measurements are also investigated. They reveal sharp variations along the vertical close to the top of the fog layer. In addition it is shown that the shape of the size distributions at the top follows a time evolution typical of a quasi-adiabatic droplet growth.

Safety profile of drugs used in the treatment of osteoporosis: a systematical review of the literature

2013-10-01

Full Text Available The range of osteoporosis treatments is increasingly large and, like any disease, the pharmacological management of patients should involve a risk/benefit evaluation to attain the greatest reduction in risk of fracture with the lowest incidence of adverse events. The aim of this review is to critically appraise the literature about the safety issues of the main pharmacological treatments of osteoporosis. This document is the result of a consensus of experts based on a systematic review of regulatory documents, randomized controlled trials, metaanalyses, pharmacovigilance surveys and case series related to possible adverse drug reactions to osteoporosis treatment with calcium and vitamin D supplements, bisphosphonates, strontium ranelate, selective estrogen receptor modulators, denosumab, and teriparatide. As expected, randomized controlled trials showed only the most common adverse events due to the samples size and the short observation time. Case series and observational studies are able to provide data about uncommon side effects, but in some cases a sure cause-effect relationship needs still to be confirmed. Consistently with methodological limitations, the newer drugs have a tolerance profile that has not been fully explored yet. Osteoporosis treatments showed an overall good tolerance profile with rare serious adverse events that, however, must be well known by the clinician who prescribes these drugs. The concern about possible adverse events should be weighed against the reduction of morbidity and mortality associated with a significant fracture risk reduction.

[Neuropsychological profiles associated with the children's oral language disorders].

Conde-Guzón, P A; Conde-Guzón, M J; Bartolomé-Albistegui, M T; Quirós-Expósito, P

Oral language disorders constitute a group of syndromes with a high prevalence among the childhood population. They form a heterogeneous group that ranges from simple problems in articulating a phoneme (dyslalias) to severe disorders affecting communication, such as children's dysarthrias and aphasias. In this paper our objective is to review the neuropsychological profiles of children who manifest different oral language disorders. Due to the wide range of clinical pictures and causations covered by children's oral language disorders, very few systematic reviews have been conducted to obtain an overall view of the neuropsychological profiles of these children. Although the linguistic signs and symptoms of these disorders are well understood, the associated neuropsychological signs and symptoms have not been studied. In some cases, these neuropsychological signs cause greater learning problems in children than the actual language problems themselves. Childhood language disorders are associated with different neuropsychological problems. The most commonly associated neuropsychological deficits are problems involving memory, attention, executive functions, motor dysfunctions, temporal perception, tactile recognition, body scheme, spatial orientation and difficulties in visual discrimination. Mnemonic disorders (essentially in short-term and working auditory memory) are usually a common denominator in the different clinical pictures that make up language disorders. The mnemonic impairment associated to dyslalias deserves special attention as this disorder is sometimes similar to that seen in language problems deriving from clinical pictures with important neurological alterations.

faculties. The geometry corresponded to "Pak B" LPT airfoil. The test section simulated LPT flow in a passage. Three experimental studies were performed: (a) Boundary layer measurements for ten baseline cases under high and low freestream turbulence conditions at five Reynolds numbers of 25,000, 50,000, 100,000, 200,000, and 300,000, based on passage exit velocity and suction surface wetted length; (b) Passive flow control studies with three thicknesses of two-dimensional bars, and two heights of three-dimensional circular cylinders with different spanwise separations, at same flow conditions as the 10 baseline cases; (c) Active flow control with oscillating synthetic (zero net mass flow) vortex generator jets, for one case with low freestream turbulence and a low Reynolds number of 25,000. The Passive flow control was successful at controlling the separation problem at low Reynolds numbers, with varying degrees of success from case to case and varying levels of impact at higher Reynolds numbers. The active flow control successfully eliminated the large separation problem for the low Reynolds number case. Very detailed data was acquired using hot-wire anemometry, including single and two velocity components, integral boundary layer quantities, turbulence statistics and spectra, turbulent shear stresses and their spectra, and intermittency, documenting transition, separation and reattachment. Models were constructed to correlate the results. The report includes a summary of the work performed and reprints of the publications describing the various studies. The folders in this supplement contain processed data in ASCII format. Streamwise pressure profiles and velocity profiles are included. The velocity profiles were acquired using single sensor and cross sensor hot-wire probes which were traversed from the wall to the freestream at various streamwise locations. In some of the flow control cases (3D Trips and Jets) profiles were acquired at multiple spanwise locations.

Full Text Available The aim of this study was to investigate phenotypic profile of B lymphocytes in peripheral blood of the patients with chronic endometritis and adnexitis. The study involved 89 women in their reproductive age (18 to 45 years with chronic endometritis (48 cases and adnexitis (41 cases. Ninety-eight healthy agematched women participated as a control group. Phenotypic B-cell subpopulations were analyzed by flow cytometry performed with direct immunofluorescent staining of peripheral cells from whole blood using the following antibody panel: CD5-FITC/CD23-PE/CD19-ECD/CD45-PC5/CD27-PC7. A significantly reduced B-lymphocyte content was revealed in peripheral blood of women with chronic endometritis and adnexitis. The reduced cell numbers occurred due to reduced B2 (main fraction of B-lymphocytes and as B1 cells (minor fraction which determines insufficient reactivity of specific humoral immune response, including immune reactions at the mucous membranes. However, percentage of B2-lymphocytes was decreased only in endometriosis, whereas patients with adnexitis showed decrease in both relative and absolute counts of this B cell subpopulation. A decreased content of naive B-cells in the peripheral blood is another feature of the B cell phenotypic profile in chronic endometritis and adnexitis. Moreover, the drop of the naive B-cell levels in patients with adnexitis proved to be more pronounced than in persons with endometritis. Expression of CD23- antigen (a low-affinity receptor for IgE has been investigated as a functional marker of B cells. All the studied peripheral B cell subpopulations expressing CD23 were decreased in the patients with chronic endometritis. The numbers of different B cell fractions expressing CD23 antigen were also reduced in the women with chronic adnexitis as compared to the levels detected in patients with chronic endometritis. Alterations of the B-cell immunity were more pronounced in chronic adnexitis, due to more extensive

Wind profiling radars operating at 915 MHz have been present at a number of regional air quality studies. The profilers can provide a continuous, accurate record of the depth of the convective mixed layer with good time resolution. Profilers also provide information about entrainment at the boundary layer top. Mixing depth data from several days of the Rural Oxidants in the Southern Environment II (ROSE II) study in Alabama in June, 1992 are presented. For several cases, chemical measurements from aircraft and ground-based instruments are shown to correspond to mixing depth and entrainment zone behavior observed by the profiler.

Psychological profile of laryngectomized patients

Directory of Open Access Journals (Sweden)

Bogdan Popescu

Full Text Available Larynx cancer is one of the most susceptible form of cancer susceptible to induce alteration of the patient’s psychological profile due to the social role that the larynx has in communication. Oral communication is severely impaired even after voice rehabilitation of the laryngectomized patients, so that the social rehabilitation is somewhat not only a medical but also a social problem. The psychological profile of these patients is altered in a way that dealing with the disease is sometimes neglected and the interaction with the outside world in terms of oral communication is totally abandoned. The starting point for depression in these cases is the acknowledgement of the disease and is, in some cases, the entire medical environment. Facial scarring, the inability to verbally interact with other human, as well as the presence of the tracheostoma, are all deciding factors in the presence of a low self-esteem for these particular patients. Psychological counseling is a mandatory approach for laryngectomized patients, in order to improve their ability to cope with cancer and providing better recovery chances.

Full Text Available Abstract Background Uptake of and adherence to the prevention of mother to child transmission of HIV (PMTCT interventions are a challenge to most women if there is no male partner involvement. Organizations which include the National AIDS Council and the Zimbabwe AIDS Prevention Project- University of Zimbabwe have been working towards mobilizing men for couple HIV testing and counseling (HTC in antenatal care (ANC. In 2013, Midlands province had 19 % males who were tested together with their partners in ANC, an increase by 9 % from 2011. However, this improvement was still far below the national target, hence this study was conducted to determine the associated factors. Methods A1:1 unmatched case control study was conducted. A case was a man who did not receive HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. A control was a man who received HIV testing and counseling together with his pregnant wife in ANC in Midlands province from January to June 2015. Simple random sampling was used to select 112 cases and 112 controls. Epi Info statistical software was used to analyze data. Written informed consent was obtained from each study participant. Results Independent factors that predicted male involvement in PMTCT were: having been previously tested as a couple (aOR 0.22, 95 % CI = 0.12, 0.41 and having time to visit the clinic (aOR 0.41, 95 % CI = 0.21, 0.80. Being afraid of knowing one’s HIV status (aOR 2.22, 95 % CI = 1.04, 4.76 was independently associated with low male involvement in PMTCT. Conclusion Multiple factors were found to be associated with male involvement in PMTCT. Routine PMTCT educational campaigns in places where men gather, community based couple HTC and accommodating the working class during weekends are essential in fostering male involvement in PMTCT thereby reducing HIV transmission to the baby.

Objective: To analyze the frequencies of histological types of lymphoma, diagnosed with complete immunohistochemical profile in younger and older age group. Study Design: Cross-sectional analytical study. Place and Duration of Study: Dow Diagnostic Research and Reference Laboratory, Dow University of Health Sciences, Karachi, from January 2009 to September 2013. Methodology: Consecutive cases of lymphomas, which were diagnosed using immunohistochemistry, were analyzed according to WHO classification. Frequency and percentages for different types of lymphomas were calculated. Hodgkin and non-Hodgkin lymphomas characteristics in two age groups of less than and more than 40 years were compared, applying chi-square test. Results: Out of the 318 cases, 79 (25 percentage) were Hodgkin Lymphomas (HL) and 239 (75 percentage) were Non-Hodgkin Lymphomas (NHL). Mixed Cellularity Hodgkin Lymphoma (MCHL) was the commonest (n=48). Amongst the NHL, 215 (89.95 percentage) were B cell lymphomas and 24 (10.05percentage) were T-cell lymphomas. Diffuse Large B-Cell Lymphoma (DLBCL) was the commonest lymphoma (n=165, 69.95 percentage of NHL). Anaplastic T-Cell Lymphoma (ALCL, n=10) was the commonest T-cell lymphoma. The frequency of HL was significantly higher in the younger age group and that of NHL was higher in the older age group (p < 0.001). Primary lymph node involvement was reported in 175 (55 percentage) and cervical lymph node was the most frequent site. Extra nodal involvement was seen in 93 (29 percentage) of all cases and was reported in 87 (36.4 percentage) of NHL and 6 (7.5 percentage) of HL. The most common extra nodal site was the gastrointestinal tract. Conclusion: Hodgkin lymphoma comprises 25 percentage and non-Hodgkin lymphoma comprises 75 percentage of all lymphomas. Both occur in younger age groups than reported in the West. B-cell NHL is three times more common than T-cell lymphoma. DLBCL is the most frequent lymphoma. ALCL is the most common T-cell, and mixed

In the past 20 years, the incidence of prostate cancer has risen rapidly. It has been ranked as the third most common malignant tumor of the male genitourinary system. Testicular metastasis is uncommon in prostate cancer. Most cases are incidentally found in the treatment of prostate cancer with orchiectomy. Therefore, we believed it was necessary to report the case of our patient with this disease. We present a case of a 69-year-old Han Chinese man with a high total prostate-specific antigen level. A transrectal ultrasound-guided prostate biopsy was performed. A pathology report showed prostate cancer tissue with a Gleason score of 4 + 4 = 8/10. Imaging findings suggested that the prostate cancer tissue involved bilateral seminal vesicles and multiple bones. Next, radioactive seed implantation was carried out, and endocrine therapy was continued after the operation. Then enlargement of the left scrotum was found along with a total prostate-specific antigen level of 19.21 ng/ml. Computed tomography of the middle abdomen and pelvic cavity revealed 2.0 × 1.3-cm lesions of the left testis. The patient underwent a left testicular high resection and right orchiectomy. The postoperative pathology report showed metastatic prostate cancer cells in the left testis. Testicular metastasis of prostate cancer is rare. Therefore, a testicular physical examination is necessary for patients without relapse to avoid a missed diagnosis. Testicular metastasis should be treated according to the principle of treatment for advanced prostate adenocarcinoma if testicular metastasis of prostate adenocarcinoma is detected.

Full Text Available Gastric cancer is the 5th most frequent cancer around the world and the 3rd most frequent reason of deaths due to cancer. Every year, about 1 million new cases are taking place, with varying geographical distribution. Gastric cancer is often metastatic to liver, lungs, and bones in hematogenous way, to peripheral lymph nodes in lymphogenous way, and to peripheral tissues in adjacency way, yet bone marrow (BM and cutaneous metastasis are quite seldom. Pancytopenia is a more frequent finding identified in BM metastasis of solid organ cancers, and isolated thrombocytopenia is less often. The human epidermal growth factor 2 (HER-2 is positive in gastric cancer at a rate of 7–34%. Here, we have presented our HER-2 positive gastric cancer incident which presented with BM and cutaneous metastasis, and has no 18F-fluoro-2-deoxi-D-glucose (FDG involvement except bone metastases.

Full Text Available The present work aims at analyzing the profiles of social networks’ users, having accomplished an online questionnaire. A sample of 230 cases was obtained (limited to a deadline of a thesis that combined this study with another about enterprises’ involvement in social networks. From the socio-demographic data obtained (age, time of day in social networks, level of education and occupational status there are different behaviors. The results highlight the need of harnessing the potential of recruitment and business partnerships/projects through social networks. This is important because the vast majority of respondents use these platforms for more than one year and a significant percentage accesses them every day. Another issue is that mobile phone connection has a significant expression, thus relevant for ubiquitous business or work applications. Regarding the actions performed, besides seeing/sending messages as the most usually done, searching for knowledge (new contents is also expressive what is relevant for innovative initiatives. Regarding the motivation factors, it is interesting that besides communication with friends and meeting old friends, the use of such platforms for professional relations has high importance what corroborates some potentials mentioned.

We present fully continuous phase screens for producing super-Gaussian focal-plane irradiance profiles. Such phase screens are constructed with the assumption of either circular symmetric near-field and far-field profiles or a separable phase screen in Cartesian co-ordinates. In each case, the phase screen is only a few waves deep. Under illumination by coherent light, such phase screens produce high order super-Gaussian profiles in the focal plane with high energy content effects of beam aberrations on the focal profiles and their energy content are also discussed

2017-12-01

Full Text Available Ureteric involvement is described rarely in nephroblastoma, the most common pediatric renal tumor. This clinicopathological, descriptive retrospective study was conducted to elucidate the prevalence and histomorphological features of ureteric involvement by nephroblastoma. Of 454 nephroblastomas diagnosed in the 25-year study period, 32 displayed ureteric involvement; 21 and 11 demonstrated prolapse and invasion, respectively. The patient cohort had a mean age of 47.3 months and mainly advanced stage disease. Pre-operative radiological and intra-operative assessments identified ureteric involvement in 4 and 13 patients, respectively, but distinction between ureteric prolapse and invasion was not possible. Histopathological assessment of the primary renal tumor demonstrated exclusive triphasichistomorphology in all 32 nephroblastomas. Favorable histology, diffuse anaplasia and nephroblastomatosis were present in 28, 4 and 7 tumors, respectively. Re-appraisal of 17 post-treated tumors were classified by SIOP criteria as mixed(6, stromal(4, anaplastic(4 and regressive(3 types. The ureteric component displayed triphasic(11, biphasic(5 and monophasic(1histomorphology. The staging profile of patients with ureteric prolapse was stages I(3, II(5, III(6, IV(6 and V(1. The staging profile of patients with ureteric invasion was stages I(0, II(2, III(3, IV(4 and V(2. Distant metastases were present in 10/32 patients. Follow-up of 32 patients confirmed 21 that were tumor-free, 7 with recurrent disease and 4 fatalities; of those that remained tumor-free, 11 had advanced disease. Even in advanced tumor stages, complete excision of the urinary tract tumor and optimal treatment of disseminated malignancy are pivotal to overall patient management and outcome.

Genomic profiling of malignant tumours has assisted clinicians in providing targeted therapies for many serious cancer-related illnesses. Although the characterisation of somatic mutations is the primary aim of tumour profiling for treatment, germline mutations may also be detected given the heterogenous origin of mutations observed in tumours. Guidance documents address the return of germline findings that have health implications for patients and their genetic relations. However, the implications of discovering a potential but unconfirmed germline finding from tumour profiling are yet to be fully explored. Moreover, as tumour profiling is increasingly applied in oncology, robust ethical frameworks are required to encourage large-scale data sharing and data aggregation linking molecular data to clinical outcomes, to further understand the role of genetics in oncogenesis and to develop improved cancer therapies. This paper reports on the results of empirical research that is broadly aimed at developing an ethical framework for obtaining informed consent to return results from tumour profiling tests and to share the biomolecular data sourced from tumour tissues of cancer patients. Specifically, qualitative data were gathered from 36 semi-structured interviews with cancer patients and oncology clinicians at a cancer treatment centre in Singapore. The interview data indicated that patients had a limited comprehension of cancer genetics and implications of tumour testing. Furthermore, oncology clinicians stated that they lacked the time to provide in depth explanations of the tumour profile tests. However, it was accepted from both patients and oncologist that the return potential germline variants and the sharing of de-identified tumour profiling data nationally and internationally should be discussed and provided as an option during the consent process. Findings provide support for the return of tumour profiling results provided that they are accompanied with an

Full Text Available Basal cell carcinoma (BCC is the most common cutaneous malignancy among Caucasians. Rare examples of aggressive and neglected BCC have been reported. Here we report a unique case of a neglected BCC with significant jaw involvement. A 50-year-old female, referred by an otorhinologist, presented with a large ulcer on her chin, which was extended to her mandibular vestibule. The ulcer was 9×5.5 cm in size, and tissue destruction, necrosis was observed in the central portion, and the mandibular bone was exposed. On intraoral examination, tooth mobility and severe bone loss were evident. Due to the primary cutaneous origin of the lesion, BCC was considered as preliminary diagnosis. Biopsy was performed and diagnosis of BCC was confirmed. The diseased mandibular bone was resected and reconstructed with a surgical plate. The soft tissue defect was reconstructed with deltopectoral flap. The patient refused secondary stage plastic surgery. Although BCC is not a lethal malignancy, if left untreated and neglected, it can result in severe destruction, disfigurement, and even mortality.

Analysis of effects of laser profiles on fast electron generation by two-dimensional Particle-In-Cell simulations

Hata, M.

2010-01-01

Complete text of publication follows. A cone-guided target is used in the Fast Ignition Realization Experiment project phase-I (FIREX-I) and optimization of its design is performed. However a laser profile is not optimized much, because the laser profile that is the best for core heating is not known well. To find that, it is useful to investigate characteristics of generated fast electrons in each condition of different laser profiles. In this research, effects of laser profiles on fast electron generation are investigated on somewhat simple conditions by two-dimensional Particle-In-Cell simulations. In these simulations, a target is made up of Au pre-plasma and Au plasma. The Au pre-plasma has the exponential profile in the x direction with the scale length L = 4.0 μm and the density from 0.10 n cr to 20 n cr . The Au plasma has the flat profile in the x direction with 10 μm width and 20 n cr . Plasma profiles are uniform in the y direction. The ionization degree and the mass number of plasmas are 40 and 197, where the ionization degree is determined by PINOCO simulations. PINOCO is a two-dimensional radiation hydrodynamics simulation code, which simulates formation of the high-density plasma during the compression phase in the fast ignition. A laser is assumed to propagate as plane wave from the negative x direction to the positive x direction. Laser profiles are supposed to be uniform in the y direction. Three different laser profiles, namely flat one with t flat = 100 fs, Gaussian one with t rise/fall = 47.0 fs and flat + Gaussian one with t rise/fall = 23.5 fs and t flat = 50 fs are used. The energy and the peak intensity are constant with E = 10 7 J/cm 2 and I L = 10 20 W/cm 2 in all cases of different laser profiles. We compare results in each condition of three different laser profiles and investigate effects of laser profiles on fast electron generation. Time-integrated energy spectra are similar in all cases of three different laser profiles. In the

High throughput analysis reveals dissociable gene expression profiles in two independent neural systems involved in the regulation of social behavior

Full Text Available Abstract Background Production of contextually appropriate social behaviors involves integrated activity across many brain regions. Many songbird species produce complex vocalizations called ‘songs’ that serve to attract potential mates, defend territories, and/or maintain flock cohesion. There are a series of discrete interconnect brain regions that are essential for the successful production of song. The probability and intensity of singing behavior is influenced by the reproductive state. The objectives of this study were to examine the broad changes in gene expression in brain regions that control song production with a brain region that governs the reproductive state. Results We show using microarray cDNA analysis that two discrete brain systems that are both involved in governing singing behavior show markedly different gene expression profiles. We found that cortical and basal ganglia-like brain regions that control the socio-motor production of song in birds exhibit a categorical switch in gene expression that was dependent on their reproductive state. This pattern is in stark contrast to the pattern of expression observed in a hypothalamic brain region that governs the neuroendocrine control of reproduction. Subsequent gene ontology analysis revealed marked variation in the functional categories of active genes dependent on reproductive state and anatomical localization. HVC, one cortical-like structure, displayed significant gene expression changes associated with microtubule and neurofilament cytoskeleton organization, MAP kinase activity, and steroid hormone receptor complex activity. The transitions observed in the preoptic area, a nucleus that governs the motivation to engage in singing, exhibited variation in functional categories that included thyroid hormone receptor activity, epigenetic and angiogenetic processes. Conclusions These findings highlight the importance of considering the temporal patterns of gene expression

Contact traction analysis for profile change during coining process

International Nuclear Information System (INIS)

Kim, Hyung Kyu; Yoon, Kyung Ho; Kang, Heung Seok; Song, Kee Nam

2002-01-01

Contact tractions are analysed in the case of the change in contact profile occurring during the coining process of a thin strip material. The changed profile is assumed as a concave circular arc in the central part of the contact region which is smoothly connected with convex circular arcs at both sides, referring to the actual measurement of the coined material. The profile is discretized and the known solutions of singular integral equations are used. Since the contact profile affects the contact traction and relevant tribological behaviour (e.g. wear) as well, an accurate definition of the profile is necessary in the analysis of material failure. Parametric study is conducted with the variation of the radii and distance of the arcs, which defines the height difference between the summits of the arcs. Considered is the contact profile, which can give the negligible variation of the traction in comparison with that before the coining process

Paradoxical undressing is a phenomenon characterizing some fatal hypothermia cases. The victims, despite low environmental temperatures, paradoxically remove their clothes due to a sudden feeling of warmth. In this report, we describe a case of suspected paradoxical undressing in a non-hypothermia case. The victim, a 51-year-old Caucasian man, was found dead wearing only sneakers and socks. All other clothing was found in his car. Postmortem investigations allowed the hypothesis of hypothermia to be ruled out and revealed the presence of a ruptured cerebral aneurysm that caused a subarachnoid hemorrhage, the latter responsible for the death. The absence of any elements suggesting a voluntary undressing or any third party's DNA profile or involvement along with the possibility that the subarachnoid hemorrhage might have determined a hypothalamic injury, somehow rendered conceivable the hypothesis of an inappropriate feeling of warmth due to hemorrhage-induced dysregulation of the hypothalamic temperature-regulating centers.

Hidden Markov models for the activity profile of terrorist groups

The main focus of this work is on developing models for the activity profile of a terrorist group, detecting sudden spurts and downfalls in this profile, and, in general, tracking it over a period of time. Toward this goal, a $d$-state hidden Markov model (HMM) that captures the latent states underlying the dynamics of the group and thus its activity profile is developed. The simplest setting of $d=2$ corresponds to the case where the dynamics are coarsely quantized as Active and Inactive, re...

Time-dependent narrow emission-line profiles of quasars and active galactic nuclei

International Nuclear Information System (INIS)

Capriotti, E.R.; Foltz, C.B.

1982-01-01

The narrow-line emitting regions of quasars and active nuclei of galaxies are assumed to consist of material undergoing gravitational infall due to acceleration by centrally located mass concentrations. Two cases are considered. In one, the material is assumed to be in the form of optically thick, similar clouds which emit line radiation monochromatically, isotropically and in inverse proportion to the square of the distance from the center of the system. In the other case, the material is assumed to be homogeneous, isothermal and to have the same ionization structure everywhere. The material is assumed to be excited by an ionizing continuum created ty a supernova-like outburst of radiation. Line profiles are computed for various combinations of epoch after outburst, continuum decay times, and spectral resolution. The computed profiles are clearly asymmetric to the blue of the profile peak and for certain combinations of epoch and decay time, clearly asymmetric to the blue of line center. The computed profiles compare well with many observed [O III] profiles

Merkel cell carcinoma (MCC) is a rare but aggressive cutaneous carcinoma. MCC typically involves dermis and although epidermotropism has been reported, MCC strictly intraepidermal or in situ (MCCIS) is exceedingly rare. Most of the cases of MCCIS described so far have other associated lesions, such as squamous or basal cell carcinoma, actinic keratosis and so on. Herein, we describe 3 patients with MCC strictly in situ, without a dermal component. Our patients were elderly. 2 of the lesions involved the head and neck area and 1 was on a finger. All tumors were strictly intraepidermal in the diagnostic biopsies, and had histomorphologic features and an immunohistochemical profile supporting the diagnosis of MCC. Excisional biopsies were performed in 2 cases and failed to reveal dermal involvement by MCC or other associated malignancies. Our findings raise the awareness that MCC strictly in situ does exist and it should be included in the differential diagnosis of Paget's or extramammary Paget's disease, pagetoid squamous cell carcinoma, melanoma and other neoplasms that typically show histologically pagetoid extension of neoplastic cells. Considering the limited number of cases reported to date, the diagnosis of isolated MCCIS should not warrant a change in management from the typical MCC. © 2017 John Wiley & Sons A/S.

2015-01-01

We, herein, report two independent cases with hereditary motor and sensory neuropathy with proximal dominant involvement (HMSN-P) inherited in an autosomal dominant fashion. Their common clinical features are slowly progressive proximal dominant muscular atrophy, fasciculations and mild to moderate distal sensory disturbance with areflexia. Nerve conduction study revealed an absence of sensory nerve action potentials, in contrast to almost normal compound muscle action potentials. Gene analysis in both patients elucidated heterozygous mutation (c.854C>T, p.Pro285Leu) in the TFG, which is an identical mutation, already described by Ishiura et al. Okinawa and Shiga are two foci of HMSN-P in Japan. Eventually, one patient is from Okinawa and the other is from a mountain village in Shiga prefecture. When we see a patient who has symptoms suggestive of motor neuron disease with sensory neuropathy, HMSN-P should be considered as a differential diagnosis despite the patient's actual resident place.

Hereditary hemorrhagic telangiectasia (HHT) or Osler-Weber-Rendu disease is an autosomal dominant disorder characterized by repeated episodes of bleeding. Multiple telangiectases consisting of thin-walled, dilated vascular channels with arteriovenous communication may involve, for example, mucocutaneous tissue, the gastrointestinal tract, and the liver, lung, and brain. We report the imaging findings of two cases of HHT involving arteriovenous malformation of both the lungs and liver, a rare condition. Chest radiography revealed a round mass, while helical CT showed a feeding artery and draining vein with arteriovenous malformation in the lung. Color Doppler sonography revealed an enlarged and tortuous hepatic artery with high systolic velocity. CT demonstrated an enlarged hepatic artery, arteriovenous shunt, and early draining hepatic vein in the liver. Celiac angiography showed arteriovenous malformation.

To define the profile of female victims of conjugal violence examined in the Legal Medicine emergency unit of the Hotel-Dieu hospital in Paris. A self-administered questionnaire with 15 questions was distributed to 100 victims. The 100 victims replied: 86 cases of violence took place usually in the home, 78 episodes of violence were multiple and complaints were rarely lodged after the first episodes. Mental and sexual violence were severe and unrecognized. Eighty women interviewed suffered from mental violence. In 43 cases, alcohol played a determining role in the onset of such violence. Female victims of conjugal violence do not have a specific profile. The law of silence persists, but the increase in the number of complaints from North African and African women is encouraging for the future.

Full Text Available Pseudoxanthoma elasticum (PXE is a rarely seen connective tissue disease which is characterized by progressive fragmentation and calcification of elastic fibers. Generally it is characterized by cutaneus, ocular and vascular system involvement and neurological complications are usually secondary to vascular insufficiency. 43 years old male patient had a progressive dysarthria, ataxia and vision loss which started many years ago referred to our clinic. Loose skin was seen on bilateral his axillar region and neck with atrophic, pale viola macular lesions on his body. There was “angiloid streaks” on fundus examination and skin biopsy showed calcified degenerated elastic fibers on middle and deep dermis. Diffuse white matter lesions were determined on cranial imaging. To keep in mind the diagnosis of rare diseases would be helpful in early diagnosis and treatment, reducing and even preventing systemic complications.

diffractometers (e.g. BM16 at ESRF and Station 2.3 at Daresbury). In the literature, convolution based profile fitting is normally associated with microstructure analysis where the sample contribution needs to be separated from the instrument contribution in an observed profile. This is no longer the case. Convolution based profile fitting can be also performed on a fully empirical basis to provide better fits to data and a greater variety of profile shapes. With convolution based profile fitting virtually any peak shape and its angular dependence can be modelled. The approach may be based on a physical model (FPA) or performed empirically. The quality of fit by convolution is normally better than using other methods. The uncertainty in derived parameters is therefore reduced. The number of parameters required to describe a pattern is normally smaller than the 'analytical function approach' and therefore parameter correlation is reduced significantly, therefore, increasing profile complexity does not necessarily require an increasing number of parameters.

IRENA Renewable Energy Country Profiles take stock of the latest developments in the field of renewables at country level around the world. Each profile combines analysis by IRENA's specialists with the latest available country data and additional information from a wide array of sources. The resulting reports provide a brief yet comprehensive picture of the situation with regard to renewable energy, including energy supply, electrical generation and grid capacity, and access. Energy policies, targets and projects are also considered, along with each country's investment climate and endowment with renewable energy resources. The energy statistics presented here span the period from 2009 until 2012, reflecting varying timelines in the source material. Since data availability differs from country to country, wider regional comparisons are possible only for the latest year with figures available for every country included. Despite the time lag in some cases, the evident differences and disparities between countries and regions around the world remain striking. The current package of country profiles is just a starting point. The geographic scope will continue to expand, and existing profiles will be enhanced with new indicators, with the whole series maintained as a live product on the IRENA website (www.irena.org)

Transcriptome profiling of petal abscission zone and functional analysis of an Aux/IAA family gene RhIAA16 involved in petal shedding in rose

2016-09-01

Full Text Available Roses are one of the most important cut flowers among ornamental plants. Rose flower longevity is largely dependent on the timing of petal shedding occurrence. To understand the molecular mechanism underlying petal abscission in rose, we performed transcriptome profiling of the petal abscission zone during petal shedding using Illumina technology. We identified a total of 2592 differentially transcribed genes (DTGs during rose petal shedding. Gene ontology term enrichment and pathway analysis revealed that major biochemical pathways the DTGs were involved in included ethylene biosynthesis, starch degradation, superpathway of cytosolic glycolysis, pyruvate dehydrogenase and TCA cycle, photorespiration and the lactose degradation III pathway. This suggests that alterations in carbon metabolism are an important part of rose petal abscission. Among these DTGs, approximately 150 genes putatively encoding transcription factors were identified in rose abscission zone. These included zinc finger, WRKY, ERF, and Aux/IAA gene families, suggesting that petal abscission involves complex transcriptional reprogramming. Approximately 108 DTGs were related to hormone pathways, of which auxin and ethylene related DTGs were the largest groups including 52 and 41 genes, respectively. These also included 12 DTGs related to gibberellin and 6 DTGs in jasmonic acid pathway. Surprisingly, no DTGs involved in the biosynthesis/signaling of abscisic acid, cytokinin, brassinosteroid, and salicylic acid pathways were detected. Moreover, among DTGs related to auxin, we identified an Aux/IAA gene RhIAA16 that was up-regulated in response to petal shedding. Down-regulation of RhIAA16 by virus-induced gene silencing in rose promoted petal abscission, suggesting that RhIAA16 plays an important role in rose petal abscission.

Localized scleroderma is a rare disease, characterized by sclerotic lesions. A variety of presentations have been described, with different clinical characteristics and specific prognosis. In scleroderma en coup de sabre (LScs) the atrophic lesion in frontoparietal area is the disease hallmark. Skin and subcutaneous are the mainly affected tissues, but case reports of muscle, cartilage, and bone involvement are frequent. These cases pose a difficult differential diagnosis with Parry-Romberg syndrome. Once considered an exclusive cutaneous disorder, the neurologic involvement present in LScs has been described in several case reports. Seizures are most frequently observed, but focal neurologic deficits, movement disorders, trigeminal neuralgia, and mimics of hemiplegic migraines have been reported. Computed tomography and magnetic resonance imaging have aided the characterization of central nervous system lesions, and cerebral angiograms have pointed to vasculitis as a part of disease pathogenesis. In this paper we describe the clinical and radiologic aspects of neurologic involvement in LScs. PMID:22319646

Full Text Available Involvement load hypothesis as a cognitive construct states that tasks with higher involvements yield better results in vocabulary retention. This comparison group designed study examined the immediate and delayed effects of tasks with different involvements in involvement load hypothesis (Laufer & Hulstijn, 2001. Applying a version of Nelson Proficiency Test as a homogenizing exclusion criterion, 33 low proficiency Iranian EFL learners were randomly assigned to three experimental groups: blank-filling, sentence making, and reading comprehension. The results of ANOVA and Kruskal-Wallis tests supported task-induced involvement in immediate posttest since the sentence making task (M=5.72 yielded better results in comparison with the other two blank-filling (M=5.45 and reading comprehension (M=3.18 tasks. Nevertheless, sentence making and blank-filling tasks of which the involvements were somehow similar did not yield significant superiority to each other. It is inferred that tasks with nearer involvements yield somehow similar results in vocabulary acquisition.

The developmental rate was significantly inhibited (P < 0.05) in response to BDE-47 and the agricultural insecticide gamma-hexachlorocyclohexane. Conversely, the ecdysteroid agonist ponasterone A (PoA) led to decreased molting and metamorphosis time (P < 0.05) from the nauplius stage to the adult stage. In particular, expression profiles of all NR genes were the highest at naupliar stages 5–6 except for SVP, FTZ-F1, and HR96 genes. Nuclear receptor USP, HR96, and FTZ-F1 genes also showed significant sex differences (P < 0.05) in gene expression levels over different developmental stages, indicating that these genes may be involved in vitellogenesis. NR gene expression patterns showed significant decreases (P < 0.05) in response to BDE-47 exposure, implying that molting and metamorphosis retardation is likely associated with NR gene expression.

Full Text Available Abstract Introduction Providing information on cancerous tissue samples during a surgical operation can help surgeons delineate the limits of a tumoral invasion more reliably. Here, we describe the use of metabolic profiling of a colon biopsy specimen by high resolution magic angle spinning nuclear magnetic resonance spectroscopy to evaluate tumoral invasion during a simulated surgical operation. Case presentation Biopsy specimens (n = 9 originating from the excised right colon of a 66-year-old Caucasian women with an adenocarcinoma were automatically analyzed using a previously built statistical model. Conclusions Metabolic profiling results were in full agreement with those of a histopathological analysis. The time-response of the technique is sufficiently fast for it to be used effectively during a real operation (17 min/sample. Metabolic profiling has the potential to become a method to rapidly characterize cancerous biopsies in the operation theater.

Background Recently, rapid advances have been made in metabolomics-based, easy-to-use early cancer detection methods using blood samples. Among metabolites, profiling of plasma free amino acids (PFAAs) is a promising approach because PFAAs link all organ systems and have important roles in metabolism. Furthermore, PFAA profiles are known to be influenced by specific diseases, including cancers. Therefore, the purpose of the present study was to determine the characteristics of the PFAA profiles in cancer patients and the possibility of using this information for early detection. Methods and Findings Plasma samples were collected from approximately 200 patients from multiple institutes, each diagnosed with one of the following five types of cancer: lung, gastric, colorectal, breast, or prostate cancer. Patients were compared to gender- and age- matched controls also used in this study. The PFAA levels were measured using high-performance liquid chromatography (HPLC)–electrospray ionization (ESI)–mass spectrometry (MS). Univariate analysis revealed significant differences in the PFAA profiles between the controls and the patients with any of the five types of cancer listed above, even those with asymptomatic early-stage disease. Furthermore, multivariate analysis clearly discriminated the cancer patients from the controls in terms of the area under the receiver-operator characteristics curve (AUC of ROC >0.75 for each cancer), regardless of cancer stage. Because this study was designed as case-control study, further investigations, including model construction and validation using cohorts with larger sample sizes, are necessary to determine the usefulness of PFAA profiling. Conclusions These findings suggest that PFAA profiling has great potential for improving cancer screening and diagnosis and understanding disease pathogenesis. PFAA profiles can also be used to determine various disease diagnoses from a single blood sample, which involves a relatively simple

Erosive genital lichen planus is a disabling, inflammatory mucocutaneous condition that can cause significant patient morbidity and loss of function. Treatment initially involves topical corticosteroids but some patients can have severe treatment-resistant courses requiring systemic immunosuppression. With potentially unfavorable adverse effect profiles and subsequent intolerance of these agents by patients, erosive lichen planus can ultimately be a challenging condition to treat effectively. We present a case of a 66-year-old woman with treatment-resistant erosive genital lichen planus who was successfully managed with mycophenolate mofetil. Although there is only weak evidence for this agent in this condition, its role in dermatology is growing due to its efficacy and advantageous adverse effect profile and should therefore be considered in patients with treatment-resistant erosive genital lichen planus. © 2015 Japanese Dermatological Association.

This study examined the profile of science' teacher instruction in Disaster Risk Reduction (DRR), as a feature of instructional quality, on students’ learning experiences. A qualitative study was done to observe teacher activities in teaching of disaster preparedness. Science teacher and 14 students at grade 4 of SDN (elementary school) Kiyaran 2 are involved as the subject of this study. Teacher’ instruction was coded with regard to preparation, action, and evaluation using observation sheets and documentation. Data analysis results showed a positive significant effect of the readiness during preparation on learning process of disaster risk reduction and an indirect effect of teacher’ action on students’ learning experiences. There is a lack of teaching materials about volcano disaster in the elementary school. Teacher found difficulties on evaluation of student achievement in disaster preparedness. These findings highlight the importance of DRR in uphold science teachers’ education. Items of teachers’ skill in preparing of DRR may be used to offer model of concrete instruction situation during university workshop for maintain teacher education.

Full Text Available Previous studies on Barrett's esophagus (BE risk factors have had differing case definitions and control groups. The purpose of this study was to examine differences in risk factors between newly diagnosed vs. prevalent BE, long- vs. short-segment BE, and endoscopy-only BE without specialized intestinal metaplasia (SIM.We conducted a cross-sectional study among eligible patients scheduled for elective esophagogastroduodenoscopy (EGD and patients eligible for screening colonoscopy, recruited from primary care clinics at a Veterans Affairs center. All participants completed a survey on demographics, gastroesophageal reflux disease (GERD symptoms and medication use prior to undergoing study EGD. We compared BE cases separately to two control groups: 503 primary care controls and 1353 endoscopy controls. Associations between risk factors and differing BE case definitions were evaluated with multivariate logistic regression models.For comparisons with primary care controls, early onset frequent GERD symptoms were more strongly associated with risk of long-segment BE (OR 19.9; 95% CI 7.96-49.7 than short-segment BE (OR 8.54; 95% CI 3.85-18.9. Likewise, the inverse association with H. pylori infection was stronger for long-segment BE (OR, 0.45; 95% CI, 0.26-0.79 than short-segment BE (OR, 0.71; 95% CI, 0.48-1.05. GERD symptoms and H. pylori infection was also more strongly associated with prevalent BE than newly diagnosed BE. Few differences were observed between BE cases and endoscopy controls. Endoscopy-only BE was associated with GERD symptoms (OR 2.25, 95% CI 1.32-3.85 and PPI/H2RA use (OR 4.44; 95% CI 2.61-7.54 but to a smaller degree than BE with SIM.We found differences in the strength and profiles of risk factors for BE. The findings support that epidemiological studies of BE should make a distinction between long and short, new and prevalent, endoscopy-only and BE with SIM as well as type of controls.

A case study using kinematic quantities derived from a triangle of VHF Doppler wind profilers

Horizontal divergence, relative vorticity, kinematic vertical velocity, and geostrophic and ageostrophic winds are computed from Colorado profiler network data to investigate an upslope snowstorm in northeastern Colorado. Horizontal divergence and relative vorticity are computed using the Gauss and Stokes theorems, respectively. Kinematic vertical velocities are obtained from the surface to 9 km by vertically integrating the continuity equation. The geostrophic and ageostrophic winds are computed by applying a finite differencing technique to evaluate the derivatives in the horizontal equations of motion. Comparison of the synoptic-scale data with the profiler network data reveals that the two datasets are generally consistent. Also, the profiler-derived quantities exhibit coherent vertical and temporal patterns consistent with conceptual and theoretical flow fields of various meteorological phenomena. It is suggested that the profiler-derived quantities are of potential use to weather forecasters in that they enable the dynamic and kinematic interpretation of weather system structure to be made and thus have nowcasting and short-term forecasting value.

Multiple Study of Case Involving Implementation of Lean Manufacturing

Full Text Available This article aims to show some factors that can cause companies to succeed or fail in their attempts to use lean manufacturing, by performing a multiple case study which presents two successful cases and three conditions of failure, in a survey of five large companies, all belonging to the metal-mechanical sector, located in Campinas and Sorocaba, both in the state of São Paulo, Brazil. The data were collected using exploratory research between the periods of January 2013 and February 2015. The results show that successful cases of lean manufacturing implementation are the result of a more organized work environment, standardization of production and service areas, employee satisfaction, productivity results and quality of the final product. Unsuccessful deployments result from poor execution and faulty planning, that has no benefit and ultimately decrease the morale of its employees, creating more distrust and frustration directly influencing the results and productivity. In other words, lean manufacturing implementation requires hard and continuous work and these procedures should be aligned with the mission and goals of companies and mainly focus on the maintenance result by using tools to monitor and track the process systematically and also making investments to eliminate waste.

Angiolipoma of the spinal column is a lesion made up of mature adipocytes with abnormal blood vessels. Around 60 cases have been reported, the majority located in the extradural space, predominantly the dorsal area. We report two cases examined in our hospital by means of plain X ray, computed tomography and magnetic resonance (MR) imaging. We review the literature and the findings with the different imaging techniques, stressing the importance of the use of MR, especially those techniques involving fat suppression, in the preoperative diagnosis of these lesions. In general, they present high signal intensity on T1-weighted images, with some areas of iso/hyposignal in the interior, a finding that differentiates them from lipomatosis, a condition that presents high signal intensify on T1-weighted sequences, but homogeneously. The administration of a paramagnetic contrast agent enhanced the images, but to a lesser extent in lesions with very high signal intensity on T1-weighted images. The signal intensity can be variable or high on T2-weighted sequences. Techniques using fat suppression are especially specific since they enhance the non-lipomatous (angiomatous) component of the lesion. The association of these MR findings with adjacent skeletal changes, consisting of progressive spinal cord compression, should lead to a suspicion of this un-common lesion, which is successfully managed with surgery.

Calcifying aponeurotic fibroma is a rare soft tissue tumor that occurs in the distal extremities of children and adolescents. We report ultrasound and X-ray findings of a calcifying aponeurotic fibroma in the finger of a 36-year-old woman, associated with distal phalangeal bone involvement. Calcifying aponeurotic fibroma is a rare, locally aggressive fibroblastic lesion occurring primarily in the palms of the hands and soles of the feet in young children and adolescents under 20 years of age. Clinical presentation is a unique, hard, and painless palpable mass. This soft tissue tumor typically infiltrates into the surrounding fascia or muscle and has a predilection for recurrence after surgical removal. However, bone involvement in calcifying aponeurotic fibroma is a very rare condition and we found only three pediatric cases in the literature. We present the ultrasound and radiographic findings of a calcifying aponeurotic fibroma in the finger of a 36-year-old woman, associated with erosive bone destruction of the distal phalanx. In summary, calcifying aponeurotic fibroma is a rare soft tissue tumor that presents as a painless mass primarily on the volar surface of the hands and plantar aspects of the feet in juveniles, but this tumor should be also included in differential diagnoses of any mass with calcification and adjacent bone involvement in the distal phalanx of the finger. In addition, US could be useful for the preoperative evaluation of digital calcifying aponeurotic fibroma.
