    Full Text Available The accumulation of high-throughput data from different experiments has facilitated the extraction of condition-specific networks over the same set of biological entities. Comparing and contrasting of such multiple biological networks is in the center of differential network biology, aiming at determining general and condition-specific responses captured in the network structure (i.e., included associations between the network components. We provide a novel way for comparison of multiple networks based on determining network clustering (i.e., partition into communities which is optimal across the set of networks with respect to a given cluster quality measure. To this end, we formulate the optimization-based problem of concurrent conditional clustering of multiple networks, termed COCONETS, based on the modularity. The solution to this problem is a clustering which depends on all considered networks and pinpoints their preserved substructures. We present theoretical results for special classes of networks to demonstrate the implications of conditionality captured by the COCONETS formulation. As the problem can be shown to be intractable, we extend an existing efficient greedy heuristic and applied it to determine concurrent conditional clusters on coexpression networks extracted from publically available time-resolved transcriptomics data of Escherichia coli under five stresses as well as on metabolite correlation networks from metabolomics data set from Arabidopsis thaliana exposed to eight environmental conditions. We demonstrate that the investigation of the differences between the clustering based on all networks with that obtained from a subset of networks can be used to quantify the specificity of biological responses. While a comparison of the Escherichia coli coexpression networks based on seminal properties does not pinpoint biologically relevant differences, the common network substructures extracted by COCONETS are supported by

    Full Text Available We report a 21-year-old female patient known to have Juvenile idiopathic arthritis (JIA who later developed multiple sclerosis (MS. The disease was documented on the brain and cerebral magnetic resonance imaging (MRI and the visual evoked potential. Our case emphasizes the need to evaluate the symptoms and brain MRI carefully. The concurrence of MS and JIA is uncommon. The possible relationship between the 2 diseases was discussed.

    Full Text Available Literature on concurrent association of sarcoidosis with lymphoproliferative malignancies other than lymphoma e.g. multiple myeloma is meager. The rarity of the situation prompted us to report this patient who was a 51-year-old woman with a 2-years history of breathlessness, cough with expectoration, chest pain and backache. Initial evaluation revealed mild anemia, increased alkaline phosphatase with chest skiagram showing both lower zone non homogenous opacities with calcified hilar lymph nodes. CECT chest showed mediastinal with bilateral hilar lymphadenopathy, parenchymal fibrosis, traction bronchiectasis, ground glass opacities, septal and peribronchovascular thickening affecting mid and lower lung zones bilaterally. MRI Dorsolumbar spine was suggestive of marrow infiltrative disorder. EBUS FNA of intrathoracic nodes, EBB and TBLB confirmed sarcoidosis. PET CT revealed hyper metabolic activity in lung, multiple lymph nodes and lytic bone lesions. Serum protein electrophoresis and immunofixation revealed a monoclonal paraprotein, immunoglobulin IgG kappa type. Bone marrow biopsy revealed an increase in plasma cells (15%, but no granulomas. Diagnosis of Indolent or multiple myeloma with sarcoidosis was established. 12 cases of sarcoidosis and multiple myeloma have been reported in literature, and mostly preceding the onset of multiple myeloma by many years, in our case both were diagnosed concurrently.

    A multiprocessor system supports multiple concurrent modes of speculative execution. Speculation identification numbers (IDs) are allocated to speculative threads from a pool of available numbers. The pool is divided into domains, with each domain being assigned to a mode of speculation. Modes of speculation include TM, TLS, and rollback. Allocation of the IDs is carried out with respect to a central state table and using hardware pointers. The IDs are used for writing different versions of speculative results in different ways of a set in a cache memory.

    Emphysematous infections of the abdomen and pelvis are potentially life-threatening conditions which require aggressive medical and surgical management. Therefore, early radiographic detection is important in the management of these conditions. Concurrent emphysematous infections involving different organs have been rarely reported, and primarily occur in immunocompromised patients. Here, we report a rare case of concurrent emphysematous cholecystitis and emphysematous pancreatitis in a 97 year old male patient.

    A priority of AIDS prevention in Botswana is to reduce multiple concurrent sexual partnerships. We analysed data from interviews with people aged 16-60 years in a 2007 national stratified random cluster sample of communities across Botswana. Among 768 male and 1784 female respondents, 10% reported multiple sexual partners in the month prior to the survey (MP1); 19% of men and 6% of women. In a multivariate analysis, men were more likely to report MP1 if they had not completed primary education (adjusted Odds Ratio (ORa) 2.13, 95% confidence intervals with adjustment for clustering (CIca) 1.19-3.85), if they were single (ORa 2.29, 95% CIca 1.28-4.11), if they had experienced intimate partner violence in the last year (ORa 2.59, 95% CIca 1.51-4.45) and if they reported acquiescence to high risk sex (ORa 8.32, 95% CIca 3.38-20.46). Women who said they earned more or the same as their partner were also more likely to report MP1 (ORa 1.76, 95% CIca 1.21-2.56). The higher rate of MP1 among men with different forms of choice-disability shows an important potential multiplication of male risk factors. Women with higher income were more likely to have more partners, questioning the idea that multiple concurrent partners is mainly a question of male disposable income.

  7. Twice upon a time: multiple concurrent temporal recalibrations of audiovisual speech.

    Audiovisual timing perception can recalibrate following prolonged exposure to asynchronous auditory and visual inputs. It has been suggested that this might contribute to achieving perceptual synchrony for auditory and visual signals despite differences in physical and neural signal times for sight and sound. However, given that people can be concurrently exposed to multiple audiovisual stimuli with variable neural signal times, a mechanism that recalibrates all audiovisual timing percepts to a single timing relationship could be dysfunctional. In the experiments reported here, we showed that audiovisual temporal recalibration can be specific for particular audiovisual pairings. Participants were shown alternating movies of male and female actors containing positive and negative temporal asynchronies between the auditory and visual streams. We found that audiovisual synchrony estimates for each actor were shifted toward the preceding audiovisual timing relationship for that actor and that such temporal recalibrations occurred in positive and negative directions concurrently. Our results show that humans can form multiple concurrent estimates of appropriate timing for audiovisual synchrony.

    Full Text Available In recent years, Instant Messaging (IM has become one of the most growing online communities, reaching millions of users at home and at work worldwide. As the community expands, assuming more than one identity at the same time becomes a common behaviour of IM users. This paper reports our ongoing research on support for multiple concurrent identities (MCI’s. Our study used an online survey and face-to-face interviews to identify user needs in supporting MCI’s in IM. The study has identified five themes including single nickname, multiple avatars, multiple statuses, boundary control and interoperability. Reflecting on these themes, we propose a framework of MCI support in IM.

    or systemic complications were reported. Conclusion These results provide preliminary evidence that two cords (affected joints can be treated concurrently with CCH with similar efficacy and safety as cords treated individually in a sequential fashion. Multiple concurrent injections would eliminate the 30-day wait between single treatments and allow for rapid and effective treatment of patients with multiple affected joints, a significant advantage for both patient and physician.

  10. Broad CTL Response in Early HIV Infection Drives Multiple Concurrent CTL Escapes.

    Recent studies have highlighted the ability of HIV to escape from cytotoxic T lymphocyte (CTL) responses that concurrently target multiple viral epitopes. Yet, the viral dynamics involved in such escape are incompletely understood. Previous analyses have made several strong assumptions regarding HIV escape from CTL responses such as independent or non-concurrent escape from individual CTL responses. Using experimental data from evolution of HIV half genomes in four patients we observe concurrent viral escape from multiple CTL responses during early infection (first 100 days of infection), providing confirmation of a recent result found in a study of one HIV-infected patient. We show that current methods of estimating CTL escape rates, based on the assumption of independent escapes, are biased and perform poorly when CTL escape proceeds concurrently at multiple epitopes. We propose a new method for analyzing longitudinal sequence data to estimate the rate of CTL escape across multiple epitopes; this method involves few parameters and performs well in simulation studies. By applying our novel method to experimental data, we find that concurrent multiple escapes occur at rates between 0.03 and 0.4 day(-1), a relatively broad range that reflects uncertainty due to sparse sampling and wide ranges of parameter values. However, we show that concurrent escape at rates 0.1-0.2 day(-1) across multiple epitopes is consistent with our patient datasets.

    Coexisting variants of porokeratosis rarely occurs. Disseminated superficial porokeratosis (DSP) is characterized by multiple uniform small annular papules distributed all over body. DSP commonly coexist with linear porokeratosis (LP), but it is uncommon for DSP to coexist with porokeratosis of Mibelli (PM). PM presents with central atrophic erythematous plaques and thread-like elevated border. It occurs mainly on extremities. Although malignant transformation can be found in the porokeratosis, there is still no report case of coexisting variants of porokeratosis concurrent with Bowen's disease. The clinical and histopathologic finding of rare coexisting variants of porokeratosis (PM and DSP) concurrent with squamous dysplasia is described.

    The prevalence and prognostic value of a concomitant diagnosis of symptomatic or asymptomatic multiple myeloma (MM), as defined by the current International Myeloma Working Group (IMWG) criteria, in patients with immunoglobulin light chain amyloidosis (AL), are unknown. We studied 46 consecutive patients with AL who underwent quantification of serum M-protein and clonal bone marrow plasma cells, as well as a comprehensive evaluation for end organ damage by MM. Using standard morphology and CD138 immunohistochemical staining, 57% and 80% of patients were found to have concomitant MM, respectively. Nine patients exhibited end organ damage consistent with a diagnosis of symptomatic MM. While overall survival was similar between AL patients with or without concurrent myeloma (1-year overall survival 68% vs. 87%; P = 0.27), a diagnosis of symptomatic myeloma was associated with inferior outcome (1-year overall survival 39% vs. 81%; P = 0.005). Quantification of bone marrow plasma cells by both standard morphology and CD138 immunohistochemistry identified a much higher prevalence of concurrent MM in patients with AL than previously reported. Evaluation of bone marrow plasma cell infiltration and presence of myeloma associated end organ damage could be clinically useful for prognostication of patients with AL. © 2013 Blackwell Publishing Ltd.

    To assess the safety and efficacy of 2 concurrent injections of collagenase clostridium histolyticum (CCH) in the same hand to treat multiple Dupuytren flexion contractures. In a multicenter, open-label phase IIIb study, 60 patients received two 0.58-mg CCH doses injected into cords affecting 2 joints in the same hand during 1 visit, followed by finger extension approximately 24 hours later. Efficacy at postinjection day 30 (change in flexion contracture and active range of motion, patient satisfaction, physician-rated improvement, and rates of clinical success [flexion contracture 5° or less]) and adverse events were summarized. The concurrent injections were most commonly administered in cords affecting metacarpophalangeal (MCP) and proximal interphalangeal (PIP) joints on the same finger (47%) or 2 MCP joints on different fingers of the same hand (37%). Mean total (sum of the 2 treated joints) flexion contracture decreased 76%, from 87° to 24° (MCP joints: 86%; PIP joints: 66%). Mean total range of motion increased from 100° to 161°. Clinical success was 76% for MCP joints and 33% for PIP joints. Most patients were very satisfied (60%) or quite satisfied (28%) with treatment. Most investigators rated treated joints as very much improved (55%) or much improved (37%). The most common treatment-related adverse events (> 75% of patients) were contusion, pain in extremity, and edema peripheral (local edema). Most adverse events were mild to moderate in severity. Serious complications included 1 pulley rupture related to study medication and 1 flexor tendon rupture (following conclusion of the study). There were no systemic complications. Results suggest that 2 affected joints can be effectively and safely treated with concurrent CCH injections. There was an increased incidence of some adverse events with concurrent treatment (pruritus, lymphadenopathy, blood blister, and skin laceration) compared with treatment of a single joint.

    Full Text Available Abstract Background Multiple health risk behaviors (HRBs among adolescents pose a threat to their health, including HIV/AIDS. Health risk behaviors such as alcohol use, smoking, substance use, and sexual risk behaviors among youth have been shown to co-occur with each others. The objectives of this study was to estimate the prevalence of single and concurrent health risk behaviors and to explore how health risk behavior is associated with socio-demographic factors and peers' behaviors. Methods A cross sectional design was used to examine health risk behaviors of adolescents between the age 14 and 19 years living in the Luangnamtha province, Lao PDR. The study was conducted between June and August, 2008. An ordinal logistic regression model that simultaneously explored demographic factors and the influence of the behavior of peers on three categories of multiple HRBs (no risk, one risk, and two or more health risk behaviors was performed. Results A total of 1360 respondents, 669 (49.1% boys with mean age 16.7 ± 1.6 and 699 (50.9% girls aged 16.1 ± 1.5 were recruited into the study. The majority reported two or fewer risk behaviors. However, multiple risk behaviors increased with age for both sexes. About 46.8% (n = 637 reported no risk, 39.3 percent (n = 535 reported one risk, 8.1 percent (n = 110 reported two risks, and 5.8 percent reported more than two health risk behaviors. The protective factors among boys were school attendance (OR = .53, CI = .33-.86, being Hmong and Yao ethnicity (OR = .48, CI-.26-.90, while being above the age of 15 (OR = 2.20, 95% CI = 1.33-3.60, Akha ethnicity (OR = 2.20, 95% CI = 1.04-4.61, peer's smoking (OR = 3.11, 95% CI = 2.1-4.6, and peer's drinking alcohol (OR = 1.88, 95% CI = 1.1-3.21 were significantly associated with the presence of multiple risk behaviors among boys. Having some education (OR = 0.17, 95% CI = 0.06-0.45, and being of Hmong and Yao ethnicity (OR = 0.38, 95% CI = 0.18-0.80 were factors that

    2014-01-01

    In this paper, a method to solve the localization of concurrent multiple acoustic sources in large open spaces is presented. The problem of the multisource localization in far-field conditions is to correctly associate the direction of arrival (DOA) estimated by a network array system to the same source. The use of systems implementing a Bayesian filter is a traditional approach to address the problem of localization in multisource acoustic scenario. However, in a real noisy open space the acoustic sources are often discontinuous with numerous short-duration events and thus the filtering methods may have difficulty to track the multiple sources. Incident signal power comparison (ISPC) is proposed to compute DOAs association. ISPC is based on identifying the incident signal power (ISP) of the sources on a microphone array using beamforming methods and comparing the ISP between different arrays using spectral distance (SD) measurement techniques. This method solves the ambiguities, due to the presence of simultaneous sources, by identifying sounds through a minimization of an error criterion on SD measures of DOA combinations. The experimental results were conducted in an outdoor real noisy environment and the ISPC performance is reported using different beamforming techniques and SD functions.

    Out-of-synchrony experiences can easily recalibrate one's subjective simultaneity point in the direction of the experienced asynchrony. Although temporal adjustment of multiple audiovisual stimuli has been recently demonstrated to be spatially specific, perceptual grouping processes that organize separate audiovisual stimuli into distinctive "objects" may play a more important role in forming the basis for subsequent multiple temporal recalibrations. We investigated whether apparent physical differences between audiovisual pairs that make them distinct from each other can independently drive multiple concurrent temporal recalibrations regardless of spatial overlap. Experiment 1 verified that reducing the physical difference between two audiovisual pairs diminishes the multiple temporal recalibrations by exposing observers to two utterances with opposing temporal relationships spoken by one single speaker rather than two distinct speakers at the same location. Experiment 2 found that increasing the physical difference between two stimuli pairs can promote multiple temporal recalibrations by complicating their non-temporal dimensions (e.g., disks composed of two rather than one attribute and tones generated by multiplying two frequencies); however, these recalibration aftereffects were subtle. Experiment 3 further revealed that making the two audiovisual pairs differ in temporal structures (one transient and one gradual) was sufficient to drive concurrent temporal recalibration. These results confirm that the more audiovisual pairs physically differ, especially in temporal profile, the more likely multiple temporal perception adjustments will be content-constrained regardless of spatial overlap. These results indicate that multiple temporal recalibrations are based secondarily on the outcome of perceptual grouping processes.

    Development of nonantibiotic-associated pseudomembranous colitis has been reported in patients receiving chemotherapy. Herein, we report a case of a 70-year-old man with diabetes mellitus and hypertension who received concurrent chemoradiation therapy after surgery for stage III pT3N1M0 rectal cancer. After completion of the therapy, the patient presented with a 2-week history of intermittent watery diarrhea (seven to nine times per day). However, the patient was afebrile and laboratory examination revealed no evidence of leukocytosis. Computed tomography disclosed inflammation of the sigmoid colon, infiltrative changes around the anastomotic site, and edematous changes straddling the serosal surface. Colonoscopic examination revealed multiple whitish patches within the radiation field, a finding suggestive of pseudomembranous colitis. No concomitant antibiotics were used during the period of concurrent chemoradiation therapy. Empirical oral metronidazole (500 mg every 8 hours) was administrated for 2 weeks. At the end of this treatment, stool culture was negative for Clostridium difficile. Physicians should be aware of the potential for the development of pseudomembranous colitis following concurrent chemoradiation therapy.

    2012-04-01

    Full Text Available A significant case report of a HIV infected patient in his fifties who experienced an excellent virological and immunological response to antiretroviral therapy (which has been modified just to prevent or avoid some adverse events, but developed a severe, sudden acute kidney failure while under a polypharmacy due to some underlying and overwhelming disorders (i.e. arterial hypertension, non-insulin-dependent diabetes mellitus, a recent acute heart infarction with remarkable remnants, and finally an anecdotal muscle-joint pain with self-prescription of non-steroideal anti-inflammatory drugs, represents the key point for a debate around the increasing frequency of “polypharmacy” in the field of HIV infection, even when HIV resistance to antiretroviral is not a concern. The continuing increase of mean age of HIV-infected population, plus the existing, sometimes unmodifiable risk factors for cardiovascular, dysmetabolic, and renal disorders, plus the adjunct of anecdotal illnesses prompting the resort to different drugs and medications, either prescribed for HIV infection itself, or taken for concurrent or subsequent diseases, or self-prescribed occasionally due to an intercurrent, trivial disorders per se, may prompt a complicated scenario culminating with a life-threatening acute renal failure of tubular origin. Our report gives us the opportunity to revise and discuss the expected interactions between antiretroviral therapy and the even growing exposure to multiple different drug and drug classes, which may be responsible for relevant drug interactions and direct or adjunctive end-organ impairment, up to life-threatening conditions, which may be avoided or prevented by considering carefully all comorbidites and co-treatments potentially administered to HIV infected patients, thirty years after the discovery of AIDS.

    The Garífuna, an ethnic minority group in Honduras, have been disproportionately affected by HIV. Previous research suggests that migration and high rates of multiple sexual partnerships are major drivers of the epidemic. Using data from a 2012 population-based survey, we assessed whether temporary migration was associated with (1) multiple sexual partnerships and (2) sexual concurrency among Garífuna men and women in Honduras. Among both men and women, temporary migration in the last year was associated with an increased likelihood of multiple sexual partnerships and with concurrency, though only the association between migration and multiple sexual partnerships among men was statistically significant (Adjusted Prevalence Ratio 1.7, 95 % CI 1.2-2.4). Migration may contribute to HIV/STI vulnerability among Garífuna men and women via increases in these sexual risk behaviors. Research conducted among men and women at elevated risk of HIV should continue to incorporate measures of mobility, including history of internal migration.

    This paper describes the Parallel Universal Matrix Multiplication Algorithms (PUMMA) on distributed memory concurrent computers. The PUMMA package includes not only the non-transposed matrix multiplication routine C = A{center_dot}B, but also transposed multiplication routines C = A{sup T}{center_dot}B, C = A{center_dot}B{sup T}, and C = A{sup T}{center_dot}B{sup T}, for a block scattered data distribution. The routines perform efficiently for a wide range of processor configurations and block sizes. The PUMMA together provide the same functionality as the Level 3 BLAS routine xGEMM. Details of the parallel implementation of the routines are given, and results are presented for runs on the Intel Touchstone Delta computer.

  3. The coexistence of terms to describe the presence of multiple concurrent diseases

    2013-08-01

    Full Text Available Background: Consensus on terminology for multiple diseases is lacking. Because of the clinical relevance and social impact of multiple concurrent diseases, it is important that concepts are clear. Objective: To highlight the diversity of terms in the literature referring to the presence of multiple concurrent diseases/conditions and make recommendations. Design: A bibliometric analysis of English-language publications indexed in the MEDLINE database from 1970 to 2012 for the terms comorbidity, multimorbidity, polymorbidity, polypathology, pluripathology, multipathology, and multicondition, and a review of definitions of multimorbidity found in English-language publications indexed from 1970 to 2012 in the MEDLINE and SCOPUS databases. Results: Comorbidity was used in 67,557 publications, multimorbidity in 434, and the other terms in three to 31 publications. At least 144 publications used the term comorbidity without referring to an index disease. Thirteen general definitions of multimorbidity were identified, but only two were frequently used (91% of publications. The most frequently used definition (48% of publications was “more than one or multiple chronic or long-term diseases/conditions”. Multimorbidity was not defined in 51% of the publications using the term. Conclusions: Comorbidity was overwhelmingly used to describe any clinical entity coexisting with an index disease under study. Multimorbidity was the term most frequently used when no index disease was designated. Several definitions of multimorbidity were found. However, most authors using the term did not define it. The use of clearly defined terms in the literature is recommended until a general consensus on the terminology of multiple coexistent diseases is reached.

However, the patient was afebrile and laboratory examination revealed no evidence of leukocytosis. Computed tomography disclosed inflammation of the sigmoid colon, infiltrative changes around the anastomotic site, and edematous changes straddling the serosal surface. Colonoscopic examination revealed multiple whitish patches within the radiation field, a finding suggestive of pseudomembranous colitis. No concomitant antibiotics were used during the period of concurrent chemoradiation therapy. Empirical oral metronidazole (500 mg every 8 hours was administrated for 2 weeks. At the end of this treatment, stool culture was negative for Clostridium difficile. Physicians should be aware of the potential for the development of

    The paper describes the case of a female patient who had at least three diseases: scleromyxedema, dermatomyositis/polymyositis (DM/PM), and paraproteinemia (monoclonal gammopathy). The concurrence of these diseases determines the atypism of their clinical and morphological patterns, as well as refractoriness to performed therapy. Scleromyxedema preceded DM followed by paraproteinemia, which does not rule out its presence in an earlier period when the patent was not carefully examined. The spe...

  7. Multiple concurrent sources localization based on a two-node distributed acoustic sensor network

    In this work, we propose a new approach to localize multiple concurrent sources using a distributed acoustic sensor network. Only two node-arrays are required in this sensor network, and each node-array consists of only two widely spaced sensors. Firstly, direction-of-arrivals (DOAs) of multiple sources are estimated at each node-array by utilizing a new pooled angular spectrum proposed in this paper, which can implement the spatial aliasing suppression effectively. Based on minimum variance distortionless response (MVDR) beamforming and the DOA estimates of the sources, the time-frequency spectra containing the corresponding energy distribution features associated with those sources are reconstructed in each node-array. Then, scale invariant feature transform (SIFT) is employed to solve the DOA association problem. Performance evaluation is conducted with field recordings and experimental results prove the effectivity and feasibility of the proposed method.

    Turner syndrome is a chromosomal abnormality in which the majority of patients have a 45XO karyotype, while a small number have a 45XO/47XXX karyotype. Congenital adrenal hyperplasia has been previously reported in patients with Turner syndrome. Although insulinomas are the most common type of functioning pancreatic neuroendocrine tumor and have been reported in patients with multiple endocrine neoplasias, the tumors have not been reported in patients with mosaic Turner syndrome. The present study reports the first case of an insulinoma in a patient with 45XO/47XXX mosaic Turner syndrome. The patient suffered from recurrent hypoglycemia, which was relieved following ingestion of glucose or food. A 5-h glucose tolerance test was performed and the levels of glucose, C-Peptide and insulin were detected. In addition, computed tomography (CT) and ultrasound scanning were performed to evaluate the possibility of an insulinoma. Pathological examination and karyotyping were performed on a surgical specimen and a whole blood sample, respectively. The patient was found to suffer from premature ovarian failure, and a physical examination was consistent with a diagnosis of Turner syndrome. An ultrasound scan demonstrated streak ovaries and the patient was found to have a 45XO/47XXX karyotype. Furthermore, a lesion was detected in the pancreas following CT scanning, which was identified as an insulinoma following surgical removal and histological examination. In conclusion, the present study reports the first case of an insulinoma in a patient with mosaic Turner syndrome. Since mosaic Turner syndrome and insulinoma are rare diseases, an association may exist that has not been previously identified.

    Background Multiple concurrent sexual relationships are one of the major challenges to HIV prevention in Tanzania. This study aims to explore sexual behaviour patterns including the practice of multiple concurrent sexual partnerships in a rural Tanzanian setting. Methods This qualitative study used focus group discussions and in-depth interviews with men and women from the community as well as ethnographic participant observations. The data was collected during 16 months of fieldwork in 2007, 2008, and 2009. The focus group discussions and in-depth interviews were transcribed verbatim and translated into English. The data was analysed through the process of latent content analysis. An open coding coding process was applied to create categories and assign themes. Findings Mafiga matatu was an expression used in this society to describe women’s multiple concurrent sexual partners, usually three partners, which was described as a way to ensure social and financial security for their families as well as to achieve sexual pleasure. Adolescent initiation ceremonies initiated and conducted by grand mothers taught young women why and how to engage successfully in multiple concurrent sexual relationships. Some men expressed support for their female partners to behave according to mafiga matatu, while other men were hesitant around this behaviour. Our findings indicate that having multiple concurrent sexual partners is common and a normative behaviour in this setting. Economical factors and sexual pleasure were identified as drivers and viewed as legitimate reason for women to have multiple concurrent sexual partnerships. Conclusions Structural changes improving women’s financial opportunities and increasing gender equality will be important to enable women to not depend on multiple concurrent sexual partnerships for financial security. Future research should explore how normative sexual behaviour changes as these structural changes take place. PMID:26683189

    Neurogenic lower urinary tract dysfunction, which is common in patients with multiple sclerosis, has a significant impact on quality of life. In this study we sought to determine brain activity processes during the micturition cycle in female patients with multiple sclerosis and neurogenic lower urinary tract dysfunction. We report brain activity on functional magnetic resonance imaging and simultaneous urodynamic testing in 23 ambulatory female patients with multiple sclerosis. Individual functional magnetic resonance imaging activation maps at strong desire to void and at initiation of voiding were calculated and averaged at Montreal Neuroimaging Institute. Areas of significant activation were identified in these average maps. Subgroup analysis was performed in patients with elicitable neurogenic detrusor overactivity or detrusor-sphincter dyssynergia. Group analysis of all patients at strong desire to void yielded areas of activation in regions associated with executive function (frontal gyrus), emotional regulation (cingulate gyrus) and motor control (putamen, cerebellum and precuneus). Comparison of the average change in activation between previously reported healthy controls and patients with multiple sclerosis showed predominantly stronger, more focal activation in the former and lower, more diffused activation in the latter. Patients with multiple sclerosis who had demonstrable neurogenic detrusor overactivity and detrusor-sphincter dyssynergia showed a trend toward distinct brain activation at full urge and at initiation of voiding respectively. We successfully studied brain activation during the entire micturition cycle in female patients with neurogenic lower urinary tract dysfunction and multiple sclerosis using a concurrent functional magnetic resonance imaging/urodynamic testing platform. Understanding the central neural processes involved in specific parts of micturition in patients with neurogenic lower urinary tract dysfunction may identify areas

    Hemangioma is rarely found in the mediastinum or lung. In the mediastinum, this tumor is usually located in the anterior mediastinum and manifests as a nonspecific soft tissue mass. In the lung, it usually presents as a well-defined nodule. To the best of our knowledge, there is no case of cavernous hemangioma concurrently involving the mediastinum and lung parenchyma, except for one case of concurrent cardiac and pulmonary hemangiomas. Here, we present an interesting case of cystic anterior and middle mediastinal masses together with multiple pulmonary nodules and ground glass opacities, which were diagnosed as cavernous hemangiomas. When similar findings are encountered, clinicians should consider hemangioma in the differential diagnosis.

    In this work we propose a comprehensive framework based on first-order logic (FOL) for mitigating (identifying and addressing) interactions between multiple clinical practice guidelines (CPGs) applied to a multi-morbid patient while also considering patient preferences related to the prescribed treatment. With this framework we respond to two fundamental challenges associated with clinical decision support: (1) concurrent application of multiple CPGs and (2) incorporation of patient preferences into the decision making process. We significantly expand our earlier research by (1) proposing a revised and improved mitigation-oriented representation of CPGs and secondary medical knowledge for addressing adverse interactions and incorporating patient preferences and (2) introducing a new mitigation algorithm. Specifically, actionable graphs representing CPGs allow for parallel and temporal activities (decisions and actions). Revision operators representing secondary medical knowledge support temporal interactions and complex revisions across multiple actionable graphs. The mitigation algorithm uses the actionable graphs, revision operators and available (and possibly incomplete) patient information represented in FOL. It relies on a depth-first search strategy to find a valid sequence of revisions and uses theorem proving and model finding techniques to identify applicable revision operators and to establish a management scenario for a given patient if one exists. The management scenario defines a safe (interaction-free) and preferred set of activities together with possible patient states. We illustrate the use of our framework with a clinical case study describing two patients who suffer from chronic kidney disease, hypertension, and atrial fibrillation, and who are managed according to CPGs for these diseases. While in this paper we are primarily concerned with the methodological aspects of mitigation, we also briefly discuss a high-level proof of concept

    Full Text Available Background. Multiple personality disorder is characterised by splited individual ego-states and splited professional community arguing whether this disorder actually exists or not.Methods. In this case report study a supportive psychodynamic psychotherapy of a patient with multiple personality disorder is presented, that lasted for 4.5 years and resulted in ego-reintegration.Conclusions. The spliting between different ego-states is powered by unneutralised aggression with the possibility of hetero- and autoaggressive behaviour. Therefore the patient in the analytically oriented psychotherapeutic process is at high risk and a safe therapeutic (e. g. in-patient setting has to be provided.

    Aim. Cemento-osseous dysplasia (COD) represents a rare group of benign fibroosseous disorders, while osteogenic sarcoma (OS) on the hand, is a malignant tumour of ominous prognosis. A combination of COD and OS is rare and sparsely reported in literature. There are only four reported cases known to the authors. The aim of this paper is to report additional cases of COD occurring concurrently with OS. Materials and Methods. The clinicoradiologic findings and histological analysis of mandibular lesions in two patients who reported at the Dental Centre of the University College Hospital, Ibadan, Nigeria, are presented. Results. The two patients were diagnosed of mandible osteosarcoma occurring concurrently with bilateral mandibular focal cemento-osseous dysplasia. Conclusion. The simultaneous occurrence of osteosarcoma and cemento-osseous dysplasia raises the question of whether COD has transformed into OS or a collision tumour has occurred and their simultaneous occurrence is just a coincidence.

  18. Concurrent exposure of bottlenose dolphins (Tursiops truncatus to multiple algal toxins in Sarasota Bay, Florida, USA.

    Full Text Available Sentinel species such as bottlenose dolphins (Tursiops truncatus can be impacted by large-scale mortality events due to exposure to marine algal toxins. In the Sarasota Bay region (Gulf of Mexico, Florida, USA, the bottlenose dolphin population is frequently exposed to harmful algal blooms (HABs of Karenia brevis and the neurotoxic brevetoxins (PbTx; BTX produced by this dinoflagellate. Live dolphins sampled during capture-release health assessments performed in this region tested positive for two HAB toxins; brevetoxin and domoic acid (DA. Over a ten-year study period (2000-2009 we have determined that bottlenose dolphins are exposed to brevetoxin and/or DA on a nearly annual basis (i.e., DA: 2004, 2005, 2006, 2008, 2009; brevetoxin: 2000, 2004, 2005, 2008, 2009 with 36% of all animals testing positive for brevetoxin (n = 118 and 53% positive for DA (n = 83 with several individuals (14% testing positive for both neurotoxins in at least one tissue/fluid. To date there have been no previously published reports of DA in southwestern Florida marine mammals, however the May 2008 health assessment coincided with a Pseudo-nitzschia pseudodelicatissima bloom that was the likely source of DA observed in seawater and live dolphin samples. Concurrently, both DA and brevetoxin were observed in common prey fish. Although no Pseudo-nitzschia bloom was identified the following year, DA was identified in seawater, fish, sediment, snails, and dolphins. DA concentrations in feces were positively correlated with hematologic parameters including an increase in total white blood cell (p = 0.001 and eosinophil (p<0.001 counts. Our findings demonstrate that dolphins within Sarasota Bay are commonly exposed to two algal toxins, and provide the impetus to further explore the potential long-term impacts on bottlenose dolphin health.

    2008-06-01

    Full Text Available With regards to obesity-related disease the impact of exercise training on health depends on the ability of exercise to promote a negative energy balance. Exercise's effect on promoting a negative energy balance is more likely to occur if exercise can induce a favourable dietary intake such as a reduced relative fat content in the diet. As such, the aim of this study was to evaluate and compare the effectiveness of aerobic training, weight training and concurrent aerobic and weight training on self-reported dietary intake. The effects of 16 weeks of aerobic (n = 12, weight (n = 13 and concurrent aerobic and weight training (n = 13 on self-reported dietary intakes were compared in previously sedentary males using the computer-based Dietary Manager® software programme. Only the concurrent aerobic and weight training group showed significant (p < 0.05 reductions in total kilocalories, carbohydrates, proteins and fats consumed while the aerobic training group showed significant reductions in fat intake at the completion of the experimental period (before: 91.0 ± 42.1g versus after: 77.1 ± 62.1g. However, no changes were observed in self-reported dietary intake in the weight training or non-exercising control groups. It is concluded that concurrent aerobic and weight training is the most effective mode of exercise at promoting a favourable improvement in self-reported dietary intake in the short term. This finding provides support for efforts to promote increases in overall physical activity in an attempt to modify the patterns of dietary intake

    Most cases of Van der Woude syndrome are caused by a mutation to interferon regulatory factor 6 on chromosome 1. Turner syndrome is caused by complete or partial absence of the second sex chromosome in girls. We describe a unique case of the two syndromes occurring concurrently though apparently independently in a girl with Van der Woude syndrome diagnosed at birth and Turner syndrome at 14 years 9 months. Short stature was initially misattributed to Van der Woude syndrome and pituitary insufficiency associated with clefts before correctly diagnosing Turner syndrome. We discuss the prevalence of delayed diagnosis of Turner syndrome, the rarity of reports of concurrent autosomal chromosome mutation and sex chromosome deletion, as well as the need to consider the diagnosis of Turner syndrome in all girls with short stature regardless of prior medical history.

    Benign multicystic mesothelioma (BMM) is a rare tumoral lesion of the peritoneum often discovered incidentally upon surgery, laparoscopy, or radiographical imaging in females of childbearing age. The etiology and question as to whether these lesions occur via a neoplastic or reactive process still remain unknown. In this report, we present two cases of BMM detected in females with concurrent colonic adenocarcinoma arising in the ileocecal region. The tumors were present in the serosa surrounding the colonic adenocarcinoma in one case, and in the omentum in the other case, which grossly mimicked peritoneal seeding of carcinoma. An immunohistochemical analysis revealed that the cells lining the cystic spaces in both lesions were positive for keratin and calretinin, confirming their mesothelial origin. To the best of our knowledge, these cases represent the first documented examples of multicystic mesothelioma concurrent with colonic adenocarcinoma.

    Full Text Available ABSTRACT Psychosis, impulse control disorders (e.g., pathological gambling and hypersexuality and repetitive behaviors such as punding are known psychiatric complications of Parkinson's disease (PD. Impulsive, compulsive and repetitive behaviors are strongly associated with dopamine-replacement therapy. We present the case of a 58-year-old man with PD and a myriad of psychiatric symptoms. Concurrent psychosis, punding and pathological gambling developed more than six years after the introduction of pramipexole and ceased shortly after the addition of quetiapine and discontinuation of pramipexole.

    The present invention is a method for identifying unknown parameters in a system having a set of governing equations describing its behavior that cannot be put into regression form with the unknown parameters linearly represented. In this method, the vector of unknown parameters is segmented into a plurality of groups where each individual group of unknown parameters may be isolated linearly by manipulation of said equations. Multiple concurrent and independent recursive least squares identification of each said group run, treating other unknown parameters appearing in their regression equation as if they were known perfectly, with said values provided by recursive least squares estimation from the other groups, thereby enabling the use of fast, compact, efficient linear algorithms to solve problems that would otherwise require nonlinear solution approaches. This invention is presented with application to identification of mass and thruster properties for a thruster-controlled spacecraft.

    Warm antibody autoimmune hemolytic anemia is due to the presence of warm agglutinins that react with protein antigens on the surface of red blood cells causing premature destruction of circulating red blood cells. We report the first case of concurrent reactive arthritis, Graves' disease, and autoimmune hemolytic anemia. A 40-year-old man with reactive arthritis, Graves' disease, type 2 diabetes mellitus, mitral valve prolapse, and Gilbert's disease presented with a one month history of jaundice, fatigue, and black stools. After diagnosis of warm autoimmune hemolytic anemia, the patient was started on prednisone 1 mg/kg with rapid improvement in his anemia and jaundice. Our subject's mother and possibly his maternal grandmother also had autoimmune hemolytic anemia, which raises the possibility of hereditary autoimmune hemolytic anemia, a rarely reported condition.

    Objective To compare alternative models for the imputation of BMIM (measured weight in kilograms/measured height in meters squared) in a longitudinal study. Methods We used data from 11,008 adults examined at wave III (2001–2002) and wave IV (2007–2008) in the National Longitudinal Study of Adolescent to Adult Health. Participants were asked their height and weight before being measured. Equations to predict wave IV BMIM were developed in an 80% random subsample and evaluated in the remaining participants. The validity of models that included BMI constructed from previously measured height and weight (BMIPM) was compared to the validity of models that used BMI calculated from concurrently self-reported height and weight (BMISR). The usefulness of including demographics and perceived weight category in those models was also examined. Results The model that used BMISR, compared to BMIPM, as the only variable produced a larger R2 (0.913 vs. 0.693), a smaller root mean square error (2.07 vs. 3.90 kg/m2) and a lower bias between normal-weight participants and those with obesity (0.98 vs. 4.24 kg/m2). The performance of the model containing BMISR alone was not substantially improved by the addition of demographics, perceived weight category or BMIPM. Conclusions Our work is the first to show that concurrent self-reports of height and weight may be more useful than previously measured height and weight for imputation of missing BMIM when the time interval between measures is relatively long. Other time frames and alternatives to in-person collection of self-reported data need to be examined. PMID:27898706

    Thyrotoxic periodic paralysis (TPP) is characterized by the presence of muscle paralysis, hypokalemia, and hyperthyroidism. We report the case of a young man with paralysis of the lower extremities, severe hypokalemia, and concurrent hyperthyroidism. TPP was suspected; therefore, treatment consisting of judicious potassium (K+) repletion and β-blocker administration was initiated. However, urinary K+ excretion rate, as well as refractoriness to treatment, was inconsistent with TPP. Chronic alcoholism was considered as an alternative cause of hypokalemia, and serum K+ was restored through vigorous K repletion and the addition of K+ -sparing diuretics. The presence of thyrotoxicosis and hypokalemia does not always indicate a diagnosis of TPP. Exclusion of TPP can be accomplished by immediate evaluation of urinary K+ excretion, acid-base status, and the amount of potassium chloride required to correct hypokalemia at presentation.

    The western North Atlantic population of right whales (Eubalaena glacialis) is one of the most critically endangered of any whale population in the world. Among the factors considered to have potentially adverse effects on the health and reproduction of E. glacialis are biotoxins produced by certain microalgae responsible for causing harmful algal blooms. The worldwide incidence of these events has continued to increase dramatically over the past several decades and is expected to remain problematic under predicted climate change scenarios. Previous investigations have demonstrated that N. Atlantic right whales are being exposed to at least two classes of algal-produced environmental neurotoxins-paralytic shellfish toxins (PSTs) and domoic acid (DA). Our primary aims during this six-year study (2001-2006) were to assess whether the whales' exposure to these algal biotoxins occurred annually over multiple years, and to what extent individual whales were exposed repeatedly and/or concurrently to one or both toxin classes. Approximately 140 right whale fecal samples obtained across multiple habitats in the western N. Atlantic were analyzed for PSTs and DA. About 40% of these samples were attributed to individual whales in the North Atlantic Right Whale Catalog, permitting analysis of biotoxin exposure according to sex, age class, and reproductive status/history. Our findings demonstrate clearly that right whales are being exposed to both of these algal biotoxins on virtually an annual basis in multiple habitats for periods of up to six months (April through September), with similar exposure rates for females and males (PSTs: ∼70-80%; DA: ∼25-30%). Notably, only one of 14 lactating females sampled did not contain either PSTs or DA, suggesting the potential for maternal toxin transfer and possible effects on neonatal animals. Moreover, 22% of the fecal samples tested for PSTs and DA showed concurrent exposure to both neurotoxins, leading to questions of interactive

    Treatment with thalidomide is associated with vascular thrombosis. The effect of thalidomide on platelet activation is unclear, although the use of aspirin is justified for thromboprophylaxis. A study on platelet activation markers was done among multiple myeloma patients receiving thalidomide therapy with warfarin as thromboprophylaxis. Strict criteria and procedure were set to avoid misinterpretation of platelet activation other than due to the thalidomide's effect. Blood specimen pre and post thalidomide therapy were used for flow cytometric analysis. Platelet surface P-selectin, CD62P expression and PAC-1 (antibody that recognizes conformational change of the GPIIb/IIIa complex) were examined by using three-colour flowcytometer. Increased expression marker for PAC-1 was observed after 4 weeks of thalidomide treatment (P thalidomide is probably multifactorial and one of them is likely through platelet activation. Further study on the affected pathway/s in the platelet activation process would confirm the exact mechanism of thalidomide-induced thrombosis and potential extended usage of this drug in future.

    Full Text Available Primary MALT lymphoma of the prostate is a rare disease which characteristically follows an indolent course. It is believed that infection or chronic inflammation may be triggers for malignant transformation in the prostate, but it is of unknown etiology. Reports of MALT lymphomas of the prostate with other concurrent primary prostate cancers are even more limited. We present the unique case of a 67 year old male with concurrent adenocarcinoma of the prostate and primary MALT lymphoma of the prostate. The patient was treated with standard therapy for prostate adenocarcinoma, which also sufficiently would treat a primary MALT lymphoma. He has been disease-free for over one year for both his primary malignancies. This case confirms that MALT lymphoma can arise concurrently with adenocarcinoma of the prostate.

  16. Measuring and modelling concurrency

    Directory of Open Access Journals (Sweden)

    Larry Sawers

    2013-02-01

    Full Text Available This article explores three critical topics discussed in the recent debate over concurrency (overlapping sexual partnerships: measurement of the prevalence of concurrency, mathematical modelling of concurrency and HIV epidemic dynamics, and measuring the correlation between HIV and concurrency. The focus of the article is the concurrency hypothesis – the proposition that presumed high prevalence of concurrency explains sub-Saharan Africa's exceptionally high HIV prevalence. Recent surveys using improved questionnaire design show reported concurrency ranging from 0.8% to 7.6% in the region. Even after adjusting for plausible levels of reporting errors, appropriately parameterized sexual network models of HIV epidemics do not generate sustainable epidemic trajectories (avoid epidemic extinction at levels of concurrency found in recent surveys in sub-Saharan Africa. Efforts to support the concurrency hypothesis with a statistical correlation between HIV incidence and concurrency prevalence are not yet successful. Two decades of efforts to find evidence in support of the concurrency hypothesis have failed to build a convincing case.

  18. Towards Composable Concurrency Abstractions

    Directory of Open Access Journals (Sweden)

    2014-06-01

    Full Text Available In the past decades, many different programming models for managing concurrency in applications have been proposed, such as the actor model, Communicating Sequential Processes, and Software Transactional Memory. The ubiquity of multi-core processors has made harnessing concurrency even more important. We observe that modern languages, such as Scala, Clojure, or F#, provide not one, but multiple concurrency models that help developers manage concurrency. Large end-user applications are rarely built using just a single concurrency model. Programmers need to manage a responsive UI, deal with file or network I/O, asynchronous workflows, and shared resources. Different concurrency models facilitate different requirements. This raises the issue of how these concurrency models interact, and whether they are composable. After all, combining different concurrency models may lead to subtle bugs or inconsistencies. In this paper, we perform an in-depth study of the concurrency abstractions provided by the Clojure language. We study all pairwise combinations of the abstractions, noting which ones compose without issues, and which do not. We make an attempt to abstract from the specifics of Clojure, identifying the general properties of concurrency models that facilitate or hinder composition.

    Background: We report the concurrence of a spinal dural arteriovenous fistula (DAVF) and multiple perimedullary arteriovenous fistulas (PAVFs) presenting with subarachnoid hemorrhage (SAH). Moreover, the bleeding site was detected 1 month after onset. Case Description: A 56-year-old man was admitted to our hospital with an SAH. A DAVF and two PAVFs were detected at the C2 level by two rounds of digital subtraction angiography. The source of bleeding, an aneurysm on the feeding artery of PAVF, was detected at the second angiogram, which was performed 1 month after the onset of SAH. The aneurysm was not demonstrated at initial angiogram because of thrombosis in the aneurysm. The DAVF was interrupted by transarterial embolization, and the two PAVFs were subsequently treated with surgery. Conclusion: A part of the whole AVFs or the source of bleeding may be invisible in the acute stage just after hemorrhage. Repeated angiography is necessary to diagnose such complex AVFs especially in case of an SAH and treatment should be performed during the subacute stage. PMID:28217381

    Full Text Available Chronic lymphedema presents as interstitial fluid retention due to a failure in the lymphatic system drainage. The affected region becomes more vulnerable immunologically and predisposed to the onset of neoplasms. Basal Cell Carcinoma is the most common sort of neoplasm, nevertheless it rarely metastisizes. Sarcomas are malignant mesenchymal neoplasms, locally aggressive, which can spread. Here is reported an infrequent case of multiple basal cell carcinoma, synchronous to a poorly differentiated pleomorphic sarcoma, both spreading to lymph nodes and arising from tissue compromised by chronic lymphedema.Linfedema crônico se manifesta pelo acúmulo de líquido intersticial por falha da drenagem linfática. A região afetada torna-se imunologicamente vulnerável e predisposta ao desenvolvimento de neoplasias. Carcinoma basocelular é a neoplasia maligna mais comum, entretanto raramente metastatiza. Sarcomas são neoplasias mesenquimais malignas, localmente agressivas e capazes de metastatizar. Apresentamos um caso raro de múltiplos carcinomas basocelulares concomitantes a sarcoma pleomórfico pouco diferenciado, metastáticos para linfonodos, originando-se em área de linfedema crônico.

    Chest radiograhs revealed evidences of dilatation of the trachea and both main bronchi, multiple air bubbles around the trachea and focal bronchopneumonia in right lower lobe. Tracheobronchomegaly is a rare condition characterized by marked dilatation of the trachea and main bronchi and frequently associated with tracheal diverticulosis, bronchiectasis, and recurrent lower respiratory tract infection. Mounier-Kuhn, in 1932, was the first to associate the presence of tracheobronchomegaly with the clinical syndrome of chronic, recurrent respiratory tract infection. Tracheobronchomegaly is believed to be extremely rare. To date, only 92 cases have been reported in the literatures. We recently encountered a case of tracheobronchomegaly associated with multiple diverticula formation. The diagnosis was made by chest radiography, computed tomography (CT), bronchography, and CT taken immediately after the bronchography.

We report a 42-year-old male who presented to our hospital with diarrhea and weight loss of six months′ duration. Ultrasonography of the abdomen revealed bilateral polycystic kidneys with multiple cystic and solid com-ponents as well as polycystic pancreas. A computerized tomography scan of the abdomen revealed bilateral multiple simple and complex renal cysts, cystic lesions in the head and body of the pancreas and a non-enhancing lesion in the left adrenal gland. The features raised the possibility of VHL syndrome and a biopsy of the kidney revealed atypical cells with a suspicion of malignancy. He underwent bilateral nephrectomy and is on maintenance dialysis since then.

    Full Text Available Abstract Introduction Thyroglossal duct carcinoma is a very rare finding and its presentation is similar to that of a benign cyst, which is a relatively common developmental abnormality that may manifest as a midline, neck mass. In general the diagnosis of thyroglossal duct carcinoma is based on the pathologic examination of the mass, but needle aspiration cytology, ultrasound and computed tomography play a role in the differential diagnosis of malignancy. Case presentation A further case of thyroglossal duct carcinoma and concurrent thyroid carcinoma with locoregional lymph node metastases affecting a 40-year-old woman followed up for 4 years is presented and discussed. Conclusion Sistrunk's surgical technique must always be the initial treatment, but in case of carcinoma further surgery, that is, thyroidectomy with or without lymph node dissection, and treatment with radioactive iodine have to be considered according to the microscopic and clinical findings. Accurate pre-operative clinical and radiological evaluation should be performed in order to plan surgical strategy.

    Dumbbell-shaped tumors consisting of 2 different tumors are extremely rare. Herein, the authors present a case of concurrent spinal schwannoma and meningioma mimicking a single cervical dumbbell-shaped tumor. A 64-year-old man presented with a 5-year history of gradually exacerbating left occipital pain without clinical evidence of neurofibromatosis. Magnetic resonance imaging showed an extradural tumor along the left C-2 nerve root with a small intradural component. The tumor was approached via a C-1 hemilaminectomy. The intradural tumor was resected together with the extradural tumor after opening the dura mater. The intradural tumor was attached to the dura mater around the exit point of the C-2 nerve root. Intraoperative biopsy revealed that the extradural tumor was a schwannoma and that the intradural tumor was a meningioma. The dura mater adjacent to the tumor was then coagulated and resected. Postoperative pathological examination confirmed the same diagnoses with no evidence of continuity between the intra- and extradural components. The patient's postoperative clinical course was uneventful. Clinicians should be aware that cervical dumbbell-shaped tumors can consist of 2 different tumors.

    2015-01-01

    Vital pulp therapy (VPT) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. The purpose of this case report was to describe successful VPT of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. After complete caries removal and access cavity preparation, the dental pulp was removed from the coronal third of the roots. To protect the remaining pulp, calcium-enriched mixture (CEM) cement was placed and adapted into the cavities; the tooth was then restored with amalgam. Six months after VPT, radiographic examination showed evidence of periradicular healing. Clinically, the tooth was functional without signs and symptoms of infection/inflammation. The successful outcome of this case suggests that diseased dental pulp (i.e. irreversible pulpitis) has the potential to heal after pulp protection with CEM biocement. PMID:26523145

    Recently, the liver micronucleus (MN) assay using young adult rats with repeated administrations has been investigated by employing a new method without partial hepatectomy or in situcollagenase perfusion as the repeated dose liver MN (RDLMN) assay by Narumi et al. (2012). In our study, in order to investigate the possibility of the RDLMN assay using young adult mice instead of rats and the feasibility of employing some genotoxicity assays along with the RDLMN assay as a combination test, two genotoxic carcinogens (N,N-diethylnitrosoamine (DEN) and cisplatin (CIS)) and a nongenotoxic carcinogen (phenobarbital sodium (PHE)) were administered to mice for 15 or 29 days. Then, the liver MN assay, peripheral blood (PB) MN assay and comet assay using the liver and kidney were concurrently performed as a combination test. DEN showed positive responses to all endpoints except MN induction in PB after 15 days of repeat administration. A cross-linking agent, CIS, showed MN induction in liver after 29 days of repeat administration, and in PB after 15 and 29 days of repeat administration, although the comet assay yielded negative responses for both organs at both sampling times. PHE yielded negative responses for all endpoints. In conclusion, it is suggested that the RDLMN assay using mice is a feasible method to be integrated into the general repeated toxicity test along with the combination assays, i.e., comet assay or PB MN assay, which would help in risk assessment for carcinogenicity by comparing the results of combination assays with each other.

    Full Text Available Context Pancreatic arteriovenous malformations (AVMs are uncommon in the gastrointestinal tract. Less than 100 cases have been identified in the medical literature. Approximately 10% of all pancreatic AVMs are sporadic. Case Report Herein, we report the first documented case of sporadic concurrent pancreatic head and tail AVMs in a 40-year-old gentleman who presented with a 10-day history of epigastric pain and one episode of hematemesis. Patient denied any history of traumatic incidents, cigarette smoking, alcohol abuse, chronic gastric/duodenal ulcer, chronic pancreatitis, chronic hepatic disease, difficulty swallowing, respiratory compromise, or weight loss. Physical examination and laboratory results were unremarkable. Contrast-enhanced computed tomography scan showed two hypervascular masses involving the pancreatic head and tail. The celiac trunk angiogram showed proliferating vascular networks involving the pancreatic head and tail. The superior mesenteric angiogram demonstrated significant vascular contribution to the pancreatic head arteriovenous malformation only. Due to the extreme locations of pancreatic AVMs in the head and tail, surgical resection of both lesions(leaving behind the normal pancreatic body was not possible. Instead, patient underwent intraoperative irradiation therapy (IORT. During the procedure, patient was surgically operated to retract healthy organs/tissues, and then a single concentrated dose of radiation therapy was precisely applied to both pancreatic head and tail AVM lesions. Patient had an uneventful postoperative recovery and was discharged home on the second postoperative day in stable condition. The patient is to be seen in clinic in a 4-month-period during which patient will be completing a 12-month period of postoperative IORT. Conclusion This is the first documented case of sporadic concurrent pancreatic head and tail AVMs. Angiography is the gold standard diagnostic modality.

    Pharmacokinetic parameters can be significantly altered for both extracorporeal life support (ECLS) and continuous renal replacement therapy (CRRT). This case report describes the pharmacokinetics of continuous-infusion meropenem in a patient on ECLS with concurrent CRRT. A 2.8-kg, 10-day-old, full-term neonate born via spontaneous vaginal delivery presented with hypothermia, lethargy, and a ~500-g weight loss from birth. She progressed to respiratory failure on hospital day 2 (HD 2) and developed sepsis, disseminated intravascular coagulation, and liver failure as a result of disseminated adenoviral infection. By HD 6, acute kidney injury was evident, with progressive fluid overload >1500 mL (+) for the admission. On HD 6 venoarterial ECLS was instituted for lung protection and fluid removal. On HD 7 she was initiated on CRRT. On HD 12, a blood culture returned positive and subsequently grew Pseudomonas aeruginosa with a minimum inhibitory concentration (MIC) for meropenem of 0.25 mg/L. She was started on vancomycin, meropenem, and amikacin. A meropenem bolus of 40 mg/kg was given, followed by a continuous infusion of 10 mg/kg/hr (240 mg/kg/day). On HD 15 (ECLS day 9) a meropenem serum concentration of 21 mcg/mL was obtained, corresponding to a clearance of 7.9 mL/kg/min. Repeat cultures from HDs 13 to 15 (ECLS days 7-9) were sterile. This meropenem regimen was successful in providing a target attainment of 100% for serum concentrations above the MIC for ≥40% of the dosing interval and was associated with a sterilization of blood in this complex patient on concurrent ECLS and CRRT circuits.

    2017-01-03

    Dengue and malaria are two common, mosquito-borne infections, which may lead to mortality if not managed properly. Concurrent infections of dengue and malaria are rare due to the different habitats of its vectors and activities of different carrier mosquitoes. The first case reported was in 2005. Since then, several concurrent infections have been reported between the dengue virus (DENV) and the malaria protozoans, Plasmodium falciparum and Plasmodium vivax. Symptoms of each infection may be masked by a simultaneous second infection, resulting in late treatment and severe complications. Plasmodium knowlesi is also a common cause of malaria in Malaysia with one of the highest rates of mortality. This report is one of the earliest in literature of concomitant infection between DENV and P. knowlesi in which a delay in diagnosis had placed a patient in a life-threatening situation. A 59-year old man staying near the Belum-Temengor rainforest at the Malaysia-Thailand border was admitted with fever for 6 days, with respiratory distress. His non-structural protein 1 antigen and Anti-DENV Immunoglobulin M tests were positive. He was treated for severe dengue with compensated shock. Treating the dengue had so distracted the clinicians that a blood film for the malaria parasite was not done. Despite aggressive supportive treatment in the intensive care unit (ICU), the patient had unresolved acidosis as well as multi-organ failure involving respiratory, renal, liver, and haematological systems. It was due to the presentation of shivering in the ICU, that a blood film was done on the second day that revealed the presence of P. knowlesi with a parasite count of 520,000/μL. The patient was subsequently treated with artesunate-doxycycline and made a good recovery after nine days in ICU. This case contributes to the body of literature on co-infection between DENV and P. knowlesi and highlights the clinical consequences, which can be severe. Awareness should be raised among

    The occurrence and diagnosis of thyroglossal duct carcinoma is very rare. The synchronous occurrence of papillary carcinomas arising in a thyroglossal duct cyst (TGDC) and thyroid gland is extremely rare. Sistrunk's surgical technique must always be the initial treatment for a TGDC. However, if there is an intra-thyroidal carcinoma or local invasion, thyroidectomy has to be considered. Accurate pre-operative radiological evaluation should be performed in order to plan a surgical strategy. The aim of this report was to review our experience in the management of papillary thyroid carcinoma associated with TGDC. Our patient was a 67-year-old man who had a mural, micro- calcified nodule within a palpable, thick-walled cyst at the level of the hyoid and synchronously, a small macro-calcified mass in the isthmus of the thyroid gland.

    BACKGROUND Thyrotoxic periodic paralysis (TPP) is commonly observed in patients with acute paralysis and hyperthyroidism. However, there is a possibility of secondary causes of hypokalemia in such a setting. CASE REPORT Herein, we present the case of a 38-year-old woman with untreated hypertension and hyperthyroidism. She presented with muscle weakness, nausea, vomiting, and diarrhea since one week. The initial diagnosis was TPP. However, biochemistry tests showed hypokalemia with metabolic alkalosis and renal potassium wasting. Moreover, a suppressed plasma renin level and a high plasma aldosterone level were noted, which was suggestive of primary aldosteronism. Abdominal computed tomography confirmed this diagnosis. CONCLUSIONS Therefore, it is imperative to consider other causes of hypokalemia (apart from TPP) in a patient with hyperthyroidism but with renal potassium wasting and metabolic alkalosis. This can help avoid delay in diagnosis of the underlying disease.

    Automated structure verification using (1)H NMR data or a combination of (1)H and heteronuclear single-quantum correlation (HSQC) data is gaining more interest as a routine application for qualitative evaluation of large compound libraries produced by synthetic chemistry. The goal of this automated software method is to identify a manageable subset of compounds and data that require human review. In practice, the automated method will flag structure and data combinations that exhibit some inconsistency (i.e. strange chemical shifts, conflicts in multiplicity, or overestimated and underestimated integration values) and validate those that appear consistent. One drawback of this approach is that no automated system can guarantee that all passing structures are indeed correct structures. The major reason for this is that approaches using only (1)H or even (1)H and HSQC spectra often do not provide sufficient information to properly distinguish between similar structures. Therefore, current implementations of automated structure verification systems allow, in principle, false positive results. Presented in this work is a method that greatly reduces the probability of an automated validation system passing incorrect structures (i.e. false positives). This novel method was applied to automatically validate 127 non-proprietary compounds from several commercial sources. Presented also is the impact of this approach on false positive and false negative results.

    Patient: Female, 38 Final Diagnosis: Primary hyperaldosteronism Symptoms: Paralysis Medication: — Clinical Procedure: — Specialty: Nephrology Objective: Challenging differential diagnosis Background: Thyrotoxic periodic paralysis (TPP) is commonly observed in patients with acute paralysis and hyperthyroidism. However, there is a possibility of secondary causes of hypokalemia in such a setting. Case Report: Herein, we present the case of a 38-year-old woman with untreated hypertension and hyperthyroidism. She presented with muscle weakness, nausea, vomiting, and diarrhea since one week. The initial diagnosis was TPP. However, biochemistry tests showed hypokalemia with metabolic alkalosis and renal potassium wasting. Moreover, a suppressed plasma renin level and a high plasma aldosterone level were noted, which was suggestive of primary aldosteronism. Abdominal computed tomography confirmed this diagnosis. Conclusions: Therefore, it is imperative to consider other causes of hypokalemia (apart from TPP) in a patient with hyper-thyroidism but with renal potassium wasting and metabolic alkalosis. This can help avoid delay in diagnosis of the underlying disease. PMID:28050008

    Full Text Available We introduce the Concurrent Collections (CnC programming model. CnC supports flexible combinations of task and data parallelism while retaining determinism. CnC is implicitly parallel, with the user providing high-level operations along with semantic ordering constraints that together form a CnC graph. We formally describe the execution semantics of CnC and prove that the model guarantees deterministic computation. We evaluate the performance of CnC implementations on several applications and show that CnC offers performance and scalability equivalent to or better than that offered by lower-level parallel programming models.

    Full Text Available A 68-year-old woman with a history of multiple myeloma presented to the clinic with pain and vision loss in her right eye. Proptosis was observed in her right eye and eye movements were restricted in all directions. Best corrected visual acuity was 3/10 in her right eye. On biomicroscopic examination, hyperemia and subconjunctival hemorrhage were present. Fundus examination of the right eye revealed optic disc edema and choroidal folds. In magnetic resonance imaging two orbital masses were detected. Based on the patient’s history and ocular examination, we evaluated the masses as orbital metastasis of multiple myeloma. Palliative radiotherapy was recommended.

    Fibromatosis is a soft tissue lesion with infiltrative capacity, and is formed of proliferation of fibroblastic and myofibroblastic cells with a significant risk for local recurrence, but no metastatic potential. Fibromatosis is uncommon in the mammary gland, and accounts for less than 0.2% of all primary breast lesions. To the best of our knowledge, it has not been described in the setting of male breast with concurrent florid-type gynecomastia. We report a rare case of a 45-year-old male presenting with a palpable breast mass that was suspicious of carcinoma clinically. Failure of exclusion of metaplastic carcinoma and other lesions in repeated core biopsies lead to excision, which documented the intra-mammary origin of the lesion and established the diagnosis of fibromatosis. The current case demonstrates that fibromatosis in the male breast may have features and a presentation that can be confused with breast cancer. When obvious breast changes and history do not correlate with routine diagnostic measures, the presence of an unusual breast or chest wall tumor, such as a fibromatosis, should be considered in the differential diagnosis.

    Kidney injury associated with lymphocytic leukemia (CLL) is typically caused by direct tumor infiltration which occasionally results in acute renal failure. Glomerular involvement presenting as proteinuria or even nephrotic syndrome is exceptionally rare. Here we report a case of 54-year-old male CLL patient with nephrotic syndrome and renal failure. The lymph node biopsy confirmed that the patients had CLL with remarkable immunoglobulin light chain amyloid deposition. The renal biopsy demonstrated the concurrence of AL amyloidosis and neoplastic infiltration. Combined treatment of fludarabine, cyclophosphamide and rituximab resulted in remission of CLL, as well as the renal disfunction and nephrotic syndrome, without recurrence during a 12-month follow-up. To our knowledge, this is the first case of CLL patient showing the nephrotic syndrome and acute renal failure caused by AL amyloidosis and neoplastic infiltration. Though AL amyloidosis caused by plasma cell dyscrasia usually responses poorly to chemotherapy, this patient exhibited a satisfactory clinical outcome due to successful inhibition of the production of amylodogenic light chains by combined chemotherapy.

    We report on a stroke patient who showed recovery of hypersomnia concurrent with the recovery of an injured ascending reticular activating system (ARAS), which was demonstrated by diffusion tensor tractography (DTT).A 70-year-old female patient underwent coiling of the left ruptured posterior communicating artery after subarachnoid hemorrhage and both extraventricular drainage for management of an intraventricular hemorrhage. At 2 months after onset, when she started rehabilitation, she exhibited intact consciousness, with the full score on the Glasgow Coma Scale: 15. However, she showed severe hypersomnia: she always fell asleep without external stimulation and the Epworth Sleepiness Scale (EPS) score was 24 (full score: 24, cut off for hypersomnia: 10). She underwent comprehensive rehabilitative therapy, including neurotropic drugs, physical therapy, and occupational therapy. Her hypersomnia has shown improvement as 14 (3 months after onset), 11 (4 months after onset), 7 (12 months after onset), and 6 (24 months after onset), respectively.On 2-month DTT, narrowing of both lower dorsal and ventral ARASs was observed on both sides: in particular, among 4 neural tracts of the lower ARAS, the right lower ventral ARAS was the narrowest. By contrast, on 24-month DTT, the 4 narrowed neural tracts of both lower dorsal and ventral ARASs were thickened compared with those of 2-month DTT.Recovery of hypersomnia with recovery of an injured lower ARAS on DTT was observed in a stroke patient. Our results suggest that evaluation of the lower ARAS using DTT might be useful for stroke patients with hypersomnia.

    Concurrent thyroid cancer (TC) and hyperthyroidism (HT) is rare though increasingly being reported. HT due to TC is much rarer and more challenging especially in Africa where TC and HT have significant case fatality rates. We present a 37-year-old Cameroonian female who had been on irregular regimens of propranolol and digoxin as treatment for worsening palpitations for 12 months. She came to our district hospital for her propranolol medication refill. We fortuitously identified features of HT and found a left uninodular goiter with no cervical lymphadenopathy. She was referred for thyroid assessment which suggested primary HT and an enlarged heterogeneous left lobe with a well-defined homogenous solid mass. We restarted her on propranolol and referred her for a course of methimazole. At the referral hospital, she also underwent a left thyroid lobectomy. The resected lobe was sent for histopathology which revealed a neoplastic nodule with features suggestive of a papillary thyroid cancer (PTC) causing HT. The patient's clinical progress postoperatively was good and there was regression of hyperthyroid symptoms. The historical, clinical, and laboratory findings were suggestive of HT due to PTC. A high index of suspicion, prompt referral and counter-referral lead to a positive outcome of such a rare case in a resource poor setting. We advocate for systematic and careful evaluation of all thyroid nodules.

    National HIV prevalence estimates across sub-Saharan Africa range from less than 1 percent to over 25 percent. Recent research proposes several explanations for the observed variation, including prevalence of male circumcision, levels of condom use, presence of other sexually transmitted infections, and practice of multiple concurrent partnerships. However, the importance of partnership concurrency for HIV transmission may depend on how it affects coital frequency with each partner. The coital dilution hypothesis suggests that coital frequency within a partnership declines with the addition of concurrent partners. Using sexual behavior data from rural Malawi and urban Kenya, we investigate the relationship between partnership concurrency and coital frequency, and find partial support for the coital dilution hypothesis. We conclude the paper with a discussion of our findings in light of the current literature on concurrency.

    Guillain-Barré syndrome and acute transverse myelitis manifest as demyelinating diseases of the peripheral and central nervous system. Concurrency of these two disorders is rarely documented in literature. A 4-year-old girl presenting with cough, fever, and an impaired walking ability was admitted to hospital. She had no previous complaints in her medical history. A physical examination revealed lack of muscle strength of the lower extremities and deep tendon reflexes. MRI could not be carried out due to technical problems; therefore, both Guillain-Barré syndrome and acute transverse myelitis were considered for the diagnosis. Intravenous immunoglobulin treatment was started as first line therapy. Because this treatment did not relieve the patient's symptoms, spinal MRI was carried out on the fourth day of admission and demyelinating areas were identified. Based on the new findings, the patient was diagnosed with acute transverse myelitis, and high dose intravenous methylprednisolone therapy was started. Electromyography findings were consistent with acute polyneuropathy affecting both motor and sensory fibers. Therefore, the patient was diagnosed with concurrency of Guillain-Barré syndrome and acute transverse myelitis. Interestingly, while concurrency of these 2 disorders is rare, this association has been demonstrated in various recent publications. Progress in diagnostic tests (magnetic resonance imaging and electrophysiological examination studies) has enabled clinicians to establish the right diagnosis. The possibility of concurrent Guillain-Barré syndrome and acute transverse myelitis should be considered if recovery takes longer than anticipated.

    Benign MS patients have a mild course of disease and show no or minimal accumulation of disability over time. Little is known about the patient reported outcomes (PROs) in benign MS. The objective of the study was to compare PROs in benign MS patients and patients with similar disease duration or disability status, and to investigate how the definition of benign MS affected this outcome. Two groups of Benign MS patients (disease duration ≥15 years, Expanded Disability Status Scale [EDSS] score ≤1.5 [Benign-1.5], or ≤3.0 [Benign-3]) were compared with four other MS groups: disease duration ≥15 years, EDSS score >3.0 (Late-MS); disease duration MS). PROs included measures of QOL, fatigue, depression, and social support. Cognitive function was also assessed. Both benign groups had better PROs than Late MS patients on all measures (p QOL, depression, and fatigue were significantly different between Benign-1.5 and Early-MS groups (p QOL than Low EDSS-1.5, but was otherwise similar. Benign-3 patients had worse depression than Early-MS (p QOL and lower fatigue (p MS had better PROs than other groups of MS patients, suggesting that both disease duration and disability influence PROs. The study also showed a difference in PROs based on the way benign MS was defined.

    Kyphoplasty has been shown to provide symptomatic relief of vertebral compression fractures refractory to medical therapy. However, few reports have focused on refracture of cemented vertebrae after kyphoplasty. The presence of cemented vertebrae refracture concurrent with cement fragmentation is an extremely rare condition. We reported an 86-year-old man with a T12 osteoporotic compression fracture undergoing the kyphoplasty treatment. The patient postoperatively continued to have back pain at the same level. The solid lumped polymethylmethacrylate (PMMA) mass and inadequate use and insufficient filling of PMMA cement were observed in postoperative radiographs and magnetic resonance image (MRI) examination. He refused to receive the surgical intervention, but had not strict compliance with oral anti-osteoporotic medications. Ten months postoperatively, refracture of osteoporotic vertebral body concurrent with cement fragmentation occurred at the previously kyphoplasty-treated vertebral level. Bone mineral analysis showed severe osteoporosis with a T-score of -4.0. The patient finally obtained therapeutic benefit of pain relief and bony union of T12 vertebral body by consistently adhering to anti-osteoporotic medication treatment. This case illustrated that patients who underwent kyphoplasty to treat osteoporotic vertebral compression fractures with intravertebral fracture should be strictly followed up and supervised in their anti-osteoporotic medication treatment. The interdigitation injection pattern of PMMA and sufficient PMMA filling with trabeculae in the kyphoplasty procedure also might prevent refracture of the cemented vertebrae concurrent with PMMA fragmentation.

    Full Text Available Abstract Background Stereotactic body radiation therapy (SBRT applied by helical tomotherapy (HT is feasible for lung cancer in clinical. Using SBRT concurrently with erlotinib for non-small cell lung cancer (NSCLC is not reported previously. Case Presentation A 77-year-old man with stage III NSCLC, received erlotinib 150 mg/day, combined with image-guided SBRT via HT. A total tumor dose of 54 Gy/9 fractions was delivered to the tumor bed. The tumor responded dramatically and the combined regimen was well tolerated. After concurrent erlotinib-SBRT, erlotinib was continued as maintenance therapy. The patient developed dyspnea three months after the combined therapy and radiation pneumonitis with interstitial lung disease was suspected. Conclusions Combination SBRT, HT, and erlotinib therapy provided effective anti-tumor results. Nonetheless, the potential risks of enhanced adverse effects between radiation and erlotinib should be monitored closely, especially when SBRT is part of the regimen.

    The 1997 standard for race and ethnicity data from the Office of Management and Budget requires the collection of data for multiple race groups. The aims of this study were to compare characteristics of multiple race children and describe race reporting for children within interracial and multiple race families. Descriptive statistics were estimated using the 1993-1995 National Health Interview Surveys. In this time period, 2.6% of children had more than one race reported. Multiple race children were a diverse group who differed from each other and their single race counterparts. For example, the percent of children reported as both Black and White who lived in a two-parent household (58.9%), was significantly less than the corresponding percents for other multiple race children (65.8%-79.6%), and between the corresponding percents for single race Black (42.7%) and single race White children (83.2%). The relationships between parental race and child's race varied. Although 3.1% of children in two-parent households lived with interracial parents, fewer than half of these children had more than one race reported. Sociodemographic variables were not associated with child's reported race among interracial families. These findings indicate that generalizations about multiple race children for research or policy purposes will be problematic.

    Sixty-four market-weight (130.0 +/- 0.65 kg) barrows (n = 16) and gilts (n = 48) were used in a split-plot design with a 2 x 2 x 2 factorial arrangement of treatments: 1) handling intensity (gentle vs. aggressive), 2) transport floor space (0.39 vs. 0.49 m(2)/pig), and 3) distance moved during handling (25 vs. 125 m) to determine the effects of multiple concurrent stressors on metabolic responses. For the handling intensity treatment, pigs were moved individually approximately 50 m through a handling course with either 0 (gentle) or 8 (aggressive) shocks from an electric goad. Pigs were loaded onto a trailer and transported for approximately 1 h at floor spaces of either 0.39 or 0.49 m(2)/pig. After transport, pigs were unloaded, and the distance moved treatment was applied; pigs were moved 25 or 125 m through a handling course using livestock paddles. Rectal temperature was measured, and blood samples (to measure blood acid-base status) were collected 2 h before the handling intensity treatment was applied and immediately after the distance moved treatment was applied. A LM sample to measure glycolytic potential was collected after the distance moved treatments on a subset of 32 pigs. There were handling intensity x distance moved interactions (P blood acid-base measurements. In general, there was no effect of distance moved on these traits when pigs were previously handled gently. However, when pigs were previously handled aggressively, pigs moved 125 compared with 25 m had greater (P blood lactate and less (P blood pH, bicarbonate, and base-excess. Pigs transported at 0.39 compared with 0.49 m(2)/pig had a greater (P floor space did not affect any other measurements. Data were analyzed by the number of stressors (the aggressive handling, restricted transport floor space, and 125-m distance moved treatments) experienced by each pig (0, 1, 2, or 3). As the number of stressors experienced by the pig increased, rectal temperature, blood lactate, and LM lactate

    Full Text Available A 15-year-old male high school football player presented with episodes of headache and complete body stiffness, especially in the arms, lower back, and thighs, immediately following a football game. This was accompanied by severe nausea and vomiting for several days. Viral meningitis was suspected by the primary clinician, and treatment with corticosteroids was initiated. Over the next several weeks, there was gradual symptom improvement and the patient returned to his baseline clinical status. The patient experienced a severe recurrence of the previous myriad of symptoms following a subsequent football game, without an obvious isolated traumatic episode. In addition, he experienced a new left sided headache, fatigue, and difficulty ambulating. He was admitted and an extensive workup was performed. CT and MRI of the head revealed concurrent intracranial and spinal subdural hematomas (SDH. Clinical workup did not reveal any evidence of coagulopathy or predisposing vascular lesions. Spinal SDH is an uncommon condition whose concurrence with intracranial SDH is an even greater clinical rarity. We suggest that our case represents an acute on chronic intracranial SDH with rebleeding, membrane rupture, and symptomatic redistribution of hematoma to the spinal subdural space.

    This paper proposes the new concurrent iterative methods without using any derivatives for finding all zeros of polynomials simultaneously. The new methods are of monotonic convergence for both simple and multiple real-zeros of polynomials and are quadratically convergent. The corresponding accelerated concurrent iterative methods are obtained too. The new methods are good candidates for the application in solving symmetric eigenproblems.

    Full Text Available Supernumerary teeth may be defined as any teeth or tooth substance in excess of the usual configuration of 20 deciduous and 32 permanent teeth. Gemination is defined as an attempt by a single tooth bud to divide, with a resultant formation of either a large tooth with a bifid crown or two completely divided teeth throughout the crown and root. Geminated supernumerary premolar is a rarity and the possibility of multiple occurrences is even rarer. An exhaustive review of English literature and a PubMed search conducted using the terms “gemination’’ and “multiple geminated supernumerary” revealed no case of multiple geminated supernumerary premolars. We report a case of multiple geminated supernumerary premolars in a 23-year-old male.

    Supernumerary teeth may be defined as any teeth or tooth substance in excess of the usual configuration of 20 deciduous and 32 permanent teeth. Gemination is defined as an attempt by a single tooth bud to divide, with a resultant formation of either a large tooth with a bifid crown or two completely divided teeth throughout the crown and root. Geminated supernumerary premolar is a rarity and the possibility of multiple occurrences is even rarer. An exhaustive review of English literature and a PubMed search conducted using the terms “gemination” and “multiple geminated supernumerary” revealed no case of multiple geminated supernumerary premolars. We report a case of multiple geminated supernumerary premolars in a 23-year-old male. PMID:26078889

    Full Text Available Introduction: Gorlin syndrome is a rare disorder with different diagnostic criteria such as mul-tiple odontogenic keratocysts, basal cell carcinomas, palmar &plantar pits, frontal bossing and hypertelorism and calcification of falx cerebri. Case Report: The case which is reported in the present study was a 27-years old woman re-ferred by a general dentist to oral medicine department of Hamadan dental faculty. On clini-cal and radiographic examination , multiple odontogenic keratocysts of jaws, multiple basal cell carcinomas, palmar pits and hypertelorism were obvious. The jaw cysts were treated with marsupialization and enucleation. The patient was referred to the dermatologist for pho-todynamic therapy. Conclusion: Most disorders of Gorlin syndrome are slight, which usually do not threat the pa-tient’s life. The prognosis of this syndrome usually depends on the dermal tumor behavior.

    2007-05-01

    The simultaneous occurrence of two different translocations affecting both alleles of the IGH gene has rarely been reported in multiple myeloma. In such a case, two different oncogenes might become transcriptionally deregulated. To investigate this hypothesis, we have characterized the plasma cell leukemia cell line SK-MM2 and a primary myeloma both carrying simultaneous IGH-FGFR3/MMSET and IGH-CCND1 fusions as shown by multicolor fluorescence in situ hybridization. Remarkably, quantitative real-time polymerase chain reaction demonstrated that only one of the oncogene loci was transcriptionally upregulated in both instances. Moreover, the upregulated oncogenes differed between both samples. Thus, biallelic IGH translocations might exert different pathogenetic effects in plasma cell disorders.

    Lekovic, Gregory; Drazin, Doniel; Mak, Albert C; Schwartz, Marc S

    2016-01-07

    Leptomeningeal disease (LMD) from breast cancer is usually a rapidly fatal condition, with median overall survival reported to be 15 weeks. Conventional treatment for LMD includes craniospinal irradiation and intrathecal (IT) methotrexate. However, the role of stereotactic radiation for leptomeningeal disease remains poorly defined. This case report describes our experience using Cyberknife radiosurgery to treat a 49-year-old female with HER-2+ breast cancer and focal/nodular leptomeningeal metastases that were refractory to craniospinal irradiation and concurrent IT chemotherapy. This combined approach--i.e., craniospinal irradiation, IT chemotherapy, and Cyberknife Radiosurgery for local, recurrent metastases--resulted in survival of 46 months with controlled disease. Based on our experience with this patient, we believe further consideration of radiosurgery for LMD is warranted.

    2012-12-01

    The Morgagni-type anterior diaphragmatic hernia is a congenital defect that is a very uncommon hernia presenting in an adult. Surgical repair is usually recommended upon diagnosis and often requires synthetic mesh for a durable, tension-free repair. The use of synthetic mesh concurrently with several of bariatric operations is controversial owing to the potential for mesh infection. In this report we describe a laparoscopic repair of a symptomatic Morgagni hernia with synthetic mesh, concurrently with sleeve gastrectomy, in a morbidly obese man. The patient was a 58-year-old man with a body mass index of 48 kg/m(2) and associated co-morbid conditions that included obstructive sleep apnea, hypertension, hyperlipidemia, impaired fasting glucose, and osteoarthritis. He was diagnosed with Morgagni hernia with exertional dyspnia. He underwent concurrent laparoscopic Morgagni hernia repair with mesh and sleeve gastrectomy. At 2 months after surgery the patient was doing well and tolerating solid foods, and his percentage excess weight loss was 35%. He was exercising regularly and had no exertional dyspnea. Laparoscopy is an attractive approach to performing multiple intra-abdominal procedures concurrently. The Morgagni hernia repair with mesh can be performed safely and effectively using a laparoscopic approach. This can be performed concurrently with bariatric surgery in the morbidly obese.

  6. Constraints meet concurrency

    CERN Document Server

    Mauro, Jacopo

    2014-01-01

    This book describes the benefits that emerge when the fields of constraint programming and concurrency meet. On the one hand, constraints can be used in concurrency theory to increase the conciseness and the expressive power of concurrent languages from a pragmatic point of view. On the other hand, problems modeled by using constraints can be solved faster and more efficiently using a concurrent system. Both directions are explored providing two separate lines of development. Firstly the expressive power of a concurrent language is studied, namely Constraint Handling Rules, that supports constraints as a primitive construct. The features of this language which make it Turing powerful are shown. Then a framework is proposed to solve constraint problems that is intended to be deployed on a concurrent system. For the development of this framework the concurrent language Jolie following the Service Oriented paradigm is used. Based on this experience, an extension to Service Oriented Languages is also proposed in ...

    Materials and methods: The Jamnapari cross goat aged two years and weighing 40 Kg was presented to the Universiti Veterinary Hospital, Universiti Putra Malaysia with the history of diarrhea and depression. The goat was examined physically. Blood and fecal samples were collected for complete blood count, serum biochemistry analysis and parasitological examination. Standard treatment plan was applied for the correction of the the problem. Results: Physical examination findings revealed the goat was in poor body condition, dull and depressed. Wet and dry fecal traces were observed around the groin region. The temperature was slightly elevated (39.5°C, the heart rate was increased (160 b/min while other parameters were within normal range. Upon auscultation of the thoracic region, moderate crackle lung sound was determined. Visual observation of the nasal cavity indicated a bilateral mucopurulent nasal discharge. The hemogram result revealed evidence of a normocytic normochromic anemia, leukocytosis, neutrophilia with left shift and monocytosis. Serum biochemistry revealed increases in gamma-glutamyl transferase (GGT, sodium, chloride, creatine kinase (CK, and hyperglobulinemia. Fecal examination revealed increased in Strongyle egg count of about 2,700 eggs per gram of feces using the Modified Mcmaster technique. From the history, physical examination and laboratory findings the goat was diagnosed with clinical parasitic gastroenteritis (PGE concurrent with moderate pneumonia infection. The therapeutic plan for this case were 45 mL of kaolin-pectin (30 mL/Kg body weight orally SID for 3 days as anti-diarrhea, 12 mL Levamisole (12 mg/Kg bwt was administered orally once as anthelminthic, fluid therapy was instituted using 1.5 L of Lactated Ringers’ solution once via intravenously. Trimethoprim-Sulfamethoxazole (1 mL/16 Kg bwt was administered intramuscularly SID for 3 days. Conclusion: Follow up examination of the goat a week post treatment indicated a good prognosis

    The appendix inflammatory process is the most common cause of chronic abdominal pain in the right lower quadrant. The frequency of appendiceal lumen obstruction by fecalith ranges from 10 to 20%; few cases of obstruction by multiple fecaliths had been reported. Sixty-nine years old male, diabetic and hypertensive in control, he underwent bowel resection 30 years previously. He completed 6 months with intermittent, mild pain in the right lower quadrant abdomen; 14 days prior to admission with increasing pain, nausea, vomiting, constipation, abdominal distension and absence of peristalsis; 12,750 leukocytes, neutrophils 90%; plain abdominal radiography without specific bowel pattern, TAC with 3 dense images in right lower quadrant; exploratory laparotomy was performed and perforated appendix with 3 free fecaliths was found. Histopathological report showed fibrosis and lymphocytic infiltrate in the muscle layer of the cecal appendix consistent with chronic appendicitis. The most common obstruction of the appendix lumen is by a single fecalith. In this case the patient had chronic appendicitis secondary to appendiceal lumen obstruction by multiple fecaliths. Reviewing the international literature any case of chronic appendicitis associated with the presence of multiple fecaliths was found. Copyright © 2016 Academia Mexicana de Cirugía A.C.

    Summary Among African American women from four rural Southeastern counties, partner's concurrency was associated with intimate partner violence, and forced sex, but not economic benefit. Background To the individual with concurrent partners, it is thought that having concurrent partnerships confers no greater risk of acquiring HIV than having multiple consecutive partnerships. However, an individual whose partner has concurrent partnerships (partner's concurrency) is at increased risk of incident HIV infection. We sought to better understand relationships characterized by partner's concurrency among African American women. Methods A total of 1,013 African American women participated in a cross-sectional survey from four rural Southeastern counties. Results Older age at first sex was associated with lower prevalence of partner's concurrency (PR, 95% CI: 0.70, 0.57-0.87), but the participant's age was not associated with partner's concurrency. After adjusting for covariates, ever having experienced intimate partner violence (IPV) or forced sex were most strongly associated with partner's concurrency (PRs, 95% CIs: 1.61, 1.23-2.11; 1.65, 1.20-2.26, respectively). Women in mutually monogamous partnerships were the most likely to receive economic support from their partners; women whose partners had concurrent partnerships did not report more economic benefit than those whose partners were monogamous. Conclusions Associations between history of IPV and forced sex with partner's concurrency suggest that women with these experiences may particularly benefit from interventions to reduce partner's concurrency in addition to support for reducing IPV and other sexual risks. To inform these interventions, further research to understand partnerships characterized by partner's concurrency is warranted. PMID:26267876

    2015-12-01

    Odontomas are tumours of odontogenic origin. In these tumours both the epithelial and mesenchymal cells undergo differentiation to form enamel and dentin with variable amounts of cementum and pulp tissue. The odontomas represent a hamartoma rather than a neoplasm. When the enamel and dentin are laid down in an organized manner it is termed as a compound odontoma wherein the tumour forms a collection of small structures resembling teeth. On the other hand, an irregular mass with no similarity to teeth is termed as a complex odontoma. There are cases of extensive and multiple compound odontomas which have been identified in either of the jaws. The present case is rare with multiple compound odontomas involving both the jaws of 45-year-old male patient. A review of seven such cases reported so far has been presented.

    Concurrent separation logic is a development of Hoare logic adapted to deal with pointers and concurrency. Since its inception, it has been enhanced with a treatment of permissions to enable sharing of data between threads, and a treatment of variables as resource alongside heap cells as resource. An introduction to the logic is given with several examples of proofs, culminating in a treatment of Simpson's 4-slot algorithm, an instance of racy non-blocking concurrency.

    Melanoma is a malignant tumor of melanocytes and the most threatening skin cancer documenting one of the highest in mortality rates in comparison to other non-skin cancers due to its potential to metastasize. Although the global incidence of melanoma has increased, the melanoma-related deaths decreased owing to the fact that melanoma is curable under the condition that early diagnosis is made and treatment is undertaken as soon as possible. Patients with primary melanoma developing a second primary melanoma are less common compared to the generalpopulation developing the first. Not only is melanoma less commonly found in Thaipatients but multiple primary melanomas (MPM) are rarely reported. The present report of a 48-year-old Thai male who presented with asymptomatic black patch on the right big toe nail and an atypical mole on the back, both ofwhich were histologically confirmed melanomas. Treatment included amputation of the right big toe and wide excision of melanoma on the back, which cleared the malignancy without recurrence until present. Although MPM are rare in Thais, the authors should be alert in cases displaying multiple moles for the possibility of melanomas. The total body examination, early diagnosis and regular follow-up are important to decrease the mortality rate in melanoma patient.

    The validity of two analogous caregiver/parent report measures of early language development in young children who are learning both English and Spanish is examined. Caregiver/parent report indices of vocabulary production and grammar were obtained for 26 children using the MacArthur Communicative Development Inventory: Words & Sentences (CDI; Fenson et al., 1994) and the Inventario del Desarrollo de Habilidades Comunicativas: Palabras y Enunciados (IDHC; Jackson-Maldonado, Bates, & Thal, 1992). Scores were significantly correlated with analogous laboratory measures in both English and Spanish, including a real-object naming task and spontaneous language use during free-play. The findings offer evidence that the CDI and IDHC provide valid assessments of early language milestones in young English- and Spanish-speaking children. Factors that may influence the validity of these tools for use with this population are also discussed.

    Although concurrent sexual partnerships (CPs) have been hypothesized to be an important risk factor for HIV in sub-Saharan Africa, the social and cultural factors that encourage CPs are not well understood. This study explored the community's perspectives on the role that parents can play in influencing their children's decision to engage in CPs. We conducted 16 in-depth interviews, 32 focus group discussions, and 16 key informant interviews with 280 adult participants in Tanzania. Data were coded; findings and conclusions were developed based on themes that emerged from coding. Three parental influences on CPs emerged: parent-child communication about sex, both silent and explicit encouragement of CPs, and parental behavior modeling. Parents are typically either too busy or too "embarrassed" to talk with their children about sex and CPs. The information parents do give is often confusing, fear-based, inadequate, and/or only focused on daughters. Parents themselves also encourage CPs through complicity of silence when their daughters come home with extra cash or consumer goods. In some cases, parents overtly encourage their children, particularly daughters, to practice CPs due to the promise of money from wealthy partners. Finally, when parents engage in CPs, the children themselves learn to behave similarly. These results suggest that parents can influence their children's decision to engage in CPs. HIV prevention interventions should address this by promoting parent-child communication about sexuality; associated disease risks and gender-equitable relationships; promoting positive parental role modeling; and educating parents on the implications of encouragement of CPs in their children.

    Full Text Available We provide an extension of concurrent Kleene algebras to account for probabilistic properties. The algebra yields a unified framework containing nondeterminism, concurrency and probability and is sound with respect to the set of probabilistic automata modulo probabilistic simulation. We use the resulting algebra to generalise the algebraic formulation of a variant of Jones' rely/guarantee calculus.

  10. Data refinement for true concurrency

    2013-05-01

    Full Text Available The majority of modern systems exhibit sophisticated concurrent behaviour, where several system components modify and observe the system state with fine-grained atomicity. Many systems (e.g., multi-core processors, real-time controllers also exhibit truly concurrent behaviour, where multiple events can occur simultaneously. This paper presents data refinement defined in terms of an interval-based framework, which includes high-level operators that capture non-deterministic expression evaluation. By modifying the type of an interval, our theory may be specialised to cover data refinement of both discrete and continuous systems. We present an interval-based encoding of forward simulation, then prove that our forward simulation rule is sound with respect to our data refinement definition. A number of rules for decomposing forward simulation proofs over both sequential and parallel composition are developed.

    Struma ovarii is an ovarian teratoma, represented in more than 50% by thyroid tissue. Five percent of struma ovarii cases have been proven to be malignant and, as in the thyroid gland, papillary thyroid carcinoma is the most common histotype arising in struma ovarii. Because of the unusual occurrence of this tumor, its management and follow-up after pelvic surgery is still controversial. Usually, total thyroidectomy followed by radioiodine treatment is the choice treatment in metastatic malignant struma ovarii, while these procedures are still controversial in non-metastatic thyroid cancer arising in struma ovarii. We report a female with follicular variant of papillary thyroid carcinoma arising in struma ovarii. After pelvic surgery, thyroid morphofunctional examinations were performed and a single nodular lesion in the left lobe was discovered. The patient underwent total thyroidectomy and histological examination showed a papillary carcinoma. Radioiodine-ablation of residual thyroid tissue was performed and levothyroxine mildly-suppressive treatment was started. A more aggressive treatment should not be denied for malignant struma ovarii without any evidence, even when apparently confined into the ovary. However, in selected cases, aggressive treatment may be advisable to decrease the risk of recurrence and to allow an accurate follow-up.

    Eduardo Barbin Zuccolotto

    Full Text Available Abstract Background and objectives: Multiple sclerosis is a demyelinating disease of the brain and spinal cord, characterized by muscle weakness, cognitive dysfunction, memory loss, and personality disorders. Factors that promote disease exacerbation are stress, physical trauma, infection, surgery, and hyperthermia. The objective is to describe the anesthetic management of a case referred to urological surgery. Case report: A female patient, 44 years of age, with multiple sclerosis, diagnosed with nephrolithiasis, referred for endoscopic ureterolythotripsy. Balanced general anesthesia was chosen, with midazolam, propofol and remifentanil target-controlled infusion; sevoflurane via laryngeal mask airway; and spontaneous ventilation. Because the patient had respiratory difficulty presenting with chest wall rigidity, it was decided to discontinue the infusion of remifentanil. There was no other complication or exacerbation of disease postoperatively. Conclusion: The use of neuromuscular blockers (depolarizing and non-depolarizing is a problem in these patients. As there was no need for muscle relaxation in this case, muscle relaxants were omitted. We conclude that the combination of propofol and sevoflurane was satisfactory, not resulting in hemodynamic instability or disease exacerbation.

    2014-01-01

    Full Text Available Problem: Even though reforms in the past 40 years mandated police response to domestic violence (DV crime, and in many states also mandated arrest, never-the-less baseline rates of DV prosecution remain low. Background: The nature of prosecution is reviewed, noting that nearly all criminal cases are resolved through plea bargaining in state and federal cases. Thus, the nature of plea bargaining is examined from a perspective of negotiable currency. Past research demonstrates that if multiple crimes are described and listed in the first responding police officer’s written report, there is a substantially greater odds that the suspect will be prosecuted and found guilty. Those extra charges can be dropped by prosecutors in exchange for a plea of guilt. Purpose: This empirical study examines a discretionary best practices crime investigation method that can be operationalized by first responding police officers, in situ, to determine whether its use leads to a significant increase in rates of prosecution and criminal conviction for DV crime. The methodology is the choice to thoroughly investigate each DV crime to uncover concurrent and also past-but-still-chargeable crimes. This optional work is time-consuming because children, neighbors, the 911 caller, and others must be contacted and interviewed. Method: Randomly selected police reports (n = 366 were found to contain 22 combinations of crime codes listed as violations, for DV and other concurrent crimes. The reports were evaluated on a number of prosecutorial outcomes. Frequency statistics were calculated, and logistic regression was used to confirm key relationships. Results: Only one third of all submitted reports listed more than one crime. For those investigations that did lead to prosecution, 97% resolved through plea bargaining. Most single charge misdemeanor DV police reports were found to be “dead upon arrival” at the prosecutor’s office, with only 29% resulting in any type of

    2007-03-01

    Full Text Available Dentigerous cyst is a developmental odontogenic cyst, which apparently develops by accumulation of fluid between reduced enamel epithelium and the tooth crown of an unerupted tooth. When observed with erupted and complete dentition the diagnosis is a surprise; as about 95% of dentigerous cysts involve the permanent dentition and only 5% are associated with supernumerary teeth. The usual age of clinical presentation of dentigerous cyst due to supernumerary tooth is during the first four decades. Mesiodens is a supernumerary tooth situated between the maxillary central incisors. More frequently the mesiodens occurs unilaterally, but it may also be bilateral, while three or more supernumerary teeth in the median region of the palate are more rarely found. We report a rare case of dentigerous cyst in association with multiple mesiodens in a 14-year-old female patient.

    Acupuncture has been widely used in alternative medicine for pain relief but may have many complications due to lack of appropriate cares. Pharmacopuncture is a sort of acupuncture that injects a herbal ingredient through a thin tube for the purpose of combining the effects of the herb and acupuncture and it has many pitfalls. The agents used in pharmacopuncture are not refined for a desired effect and not produced by sterile standard processes under strict medical surveillance. We report a case of a 44-yr-old male patient who had multiple abscesses in the psoas region with fever, right low back and hip pain that began after the pharmacopuncture treatment. This case shows that although pharmacopuncture has been practiced widely, it is important that the appropriate aseptic technique should be used to prevent severe infections and other complications.

    Full text: Introduction: Hereditary Multiple Exostosis (HME) or multiple osteochondromatosis is a skeletal development anomaly which is characterized by generalized exostoses in the bones, mainly in long bone metaphyses, appearing during childhood and adolescence. The transmission is autosomal dominant, its prevalence varies from 1/50,000 to 9/1,000,000 in Europe, and around 10% of cases show no family history. Case Report: Description of an HME case with two secondary malignization episodes. The data was taken from the patient's chart and from imaging exams from the hospital files. WASB, a 19-year-old male, hospitalized after being pre-diagnosed with HME and complaints of bone-consistent mass in the right gluteal region and a lump in the posterior region of the right leg, associated to multiple bone lumps all over the body. A magnetic resonance imaging (MRI) was performed along with a bone scintillography with {sup 99m}Tc-MDP which showed multiple osteogenic lesions in the thorax, pelvic bones and long bones with periarticular prevalence in the lower limbs. The suspicion of malignancy in the right iliac area was raised due to the MRI result and to the higher intensity captured in the scintillography, confirming chondrosarcoma grade I of malignancy in the biopsy. The patient suffered interileo abdominalis amputation of the right lower limb with good evolution and control scintillography performed after 1 and 1,5 years. In the second controlling procedure, the patient complained about pain in the left knee, and a MRI suggested a new secondary malignization. The hypothesis of a head of left fibula osteochondroma with signs of aggressiveness was confirmed following surgery. Discussion: In HME, the exostoses grow along with the individual, ceasing with the epiphyseal fusion. The growth of these formations after skeletal maturation suggests activity of exostoses and, in most times, it is a sign of malignant transformation, which turns almost every time into

    This report has been prepared by the staff of the State of Nevada Agency for Nuclear Projects/Nuclear Waste Project Office (NWPO) in response to Assembly Concurrent Resolution No. 8 (ACR 8), passed by the Nevada State Legislature in 1987. ACR 8 directed the NWPO, in cooperation with affected local governments and the Legislative committee on High-Level Radioactive Waste, to prepare this report which scrutinizes the US Department of Energy`s (DOE) plans for transportation of high-level radioactive waste to the proposed yucca Mountain repository, which reviews the regulatory structure under which shipments to a repository would be made and which presents NWPO`s plans for addressing high-level radioactive waste transportation issues. The report is divided into three major sections. Section 1.0 provides a review of DOE`s statutory requirements, its repository transportation program and plans, the major policy, programmatic, technical and institutional issues and specific areas of concern for the State of Nevada. Section 2.0 contains a description of the current federal, state and tribal transportation regulatory environment within which nuclear waste is shipped and a discussion of regulatory issues which must be resolved in order for the State to minimize risks and adverse impacts to its citizens. Section 3.0 contains the NWPO plan for the study and management of repository-related transportation. The plan addresses four areas, including policy and program management, regulatory studies, technical reviews and studies and institutional relationships. A fourth section provides recommendations for consideration by State and local officials which would assist the State in meeting the objectives of the plan.

  1. Concurrent development of testicular seminoma and choriocarcinoma of the superior mediastinum, presented as cervical mass: a case report and implications about pathogenesis of germ-cell tumours

    2006-11-01

    Full Text Available Abstract Background Synchronous presentation of more than one germ cell tumours of different histology in the same patient is considered to be very rare. In these cases of multiple germ cell tumours, strong theoretical and clinical data suggest an underlying common pathogenetic mechanism concerning genetic instability or abnormalities during the pluripotent embryonic differentiation and maturation of the germ cell. Case presentation A 25 year-old young man presented with an enlarging, slightly painful left cervical mass. Despite the initial disorientation of the diagnosis to a possible thyroid disorder, the patient underwent complete surgical resection of the mass revealing mediastinal choriocarcinoma. Subsequent ultrasound of the scrotum indicated the presence of a small lobular node in the upper pole of the left testicle and the patient underwent radical left inguinal orchiectomy disclosing a typical seminoma. Based on these results, the patient received 4 cycles of Bleomycin, Etoposide and Platinum chemotherapy experiencing only mild toxicity and resulting in complete ongoing clinical and biochemical remission. Conclusion The pathogenesis of concurrent germ cell tumours in the same patient remains an area of controversy. Although the genetic instability of the pluripotent germ cell offers an adequate explanation, the possibility of metastasis from the primary, less differentiated tumour to a distant location as a more mature subtype cannot be excluded. Possible development of a metastatic site of different histology and thus biological behaviour (e.g choriocarcinoma should be anticipated. Furthermore, urologists, pathologists and medical oncologists should be meticulous in the original pathological diagnosis in these patients, since there is a significant frequency of germ cell tumours with mixed or overlapping histological elements with diverse potential of evolution and differentiation.

    Concurrent object-oriented programming in Beta is based on semaphores and coroutines and the ability to define high-level concurrency abstractions like monitors, and rendezvous-based communication, and their associated schedulers. The coroutine mechanism of SIMULA has been generalized...... into the notions of concurrent and alternating objects. Alternating objects may be used to start a cooperative thread for each possible blocking communication and is thus an alternative to asynchronous messages and guarded commands. Beta like SIMULA, the first OO language, was designed as a language for modeling...... as well as programming, and we describe how this has had an impact on the design of the language. Although Beta supports the definition of high-level concurrency abstractions, the use of these rely on the discipline of the programmer as is the case for Java and other mainstream OO languages.

  3. Barriers in Concurrent Separation Logic

    Hobor, Aquinas; Gherghina, Cristian

    We develop and prove sound a concurrent separation logic for Pthreads-style barriers. Although Pthreads barriers are widely used in systems, and separation logic is widely used for verification, there has not been any effort to combine the two. Unlike locks and critical sections, Pthreads barriers enable simultaneous resource redistribution between multiple threads and are inherently stateful, leading to significant complications in the design of the logic and its soundness proof. We show how our logic can be applied to a specific example program in a modular way. Our proofs are machine-checked in Coq.

    The cases of gigantism sisters with somatotroph adenomas unrelated to multiple endocrine neoplasia (MEN) Type 1 are reported. The sisters grew rapidly since they were 5 or 6 years old and were diagnosed to have gigantism with pituitary adenoma by computed tomographic scan and magnetic resonance imaging. A serum endocrinological examination showed the elevated growth hormone values. After thyroxine-releasing hormone stimulation, growth hormone values exhibited a paradoxical rise. They were supposed to be unrelated to MEN Type 1, because analysis of the 11th chromosomes and the other endocrine functions were normal. They were operated on by the transphenoidal method. Immunohistochemical staining of both tumor specimens confirmed somatotroph adenomas. Pituitary adenoma associated with MEN Type 1 is a well-recognized entity. However, the sporadic occurrence of pituitary adenoma unrelated to MEN Type 1, especially in siblings, is extremely rare. Fifteen cases of pituitary adenomas in siblings were described in the literature. As for gigantism, only two brothers were reported. Our case of gigantism sisters is the second sporadic case. In our review of the isolated cases of pituitary adenoma in siblings described in the literature, 12 (70%) of 17 cases including ours are acromegaly or gigantism. This incidence is much higher than that of MEN Type 1 patients with pituitary adenomas. The cause of the familial occurrence of pituitary adenomas is still unclear, although autosomal recessive inheritance has been suggested. It has been stated that point mutations in codon 201 or 227 of the Gs alpha gene located in chromosome 20 were found in about 35 to 40% of somatotroph adenomas.(ABSTRACT TRUNCATED AT 250 WORDS)

    Several studies have confirmed that maltreatment and abuse in childhood are related to conduct problems. Less is known about such relationships with concurrent adversities in adolescence and, also, when compared with other severe adversities and possible multiple additive effects. The study encompassed a community population of 4881 adolescents 15-16 years of age 50.1 % boys and 49.9 % girls. Youth with and without conduct problem scores within the deviant range on the Strength and Difficulties Questionnaire (SDQ) was compared on 12 concurrent adversities. Based on self-reports, 4.4 % of the adolescents had conduct problem scores within the deviant range and more girls (5.1 %) than boys (3.7 %). In the deviant conduct problem group, 65.1 % had experienced two or more concurrent adversities compared with 26.3 % of youths in the non-deviant group (OR 5.23, 95 % CI 3.91-7.01). Likewise, the deviant conduct problem group was from 1.71 to 8.43 times more at the risk of experiencing the different adversities. Parental mental health problems and experiences of violence were multivariately strongest associated with conduct problem scores within the deviant range on the SDQ. A strong multiple additive relationship with adversities was found. Two-thirds of youth with SDQ conduct problem scores within the deviant range reported two or more concurrent adversities. Clinicians should seek information about kinds and amount of possible traumatic adversities in youth with conduct problems and offer evidence based treatment.

    2001-07-01

    Multiple cutaneous xanthomas, associated with fasting hyperlipidaemia, are described in a 9-month-old domestic long-haired cat. A severely pruritic, papular, and crusting dermatitis affecting the head and neck, initially diagnosed as lesions of the eosinophilic granuloma complex, progressively developed on the head and pinnae. Pruritus was controlled with administration of prednisolone and chlorambucil. Repeat histological examination confirmed the diagnosis of cutaneous xanthoma and concurrent mild demodicosis. Marked fasting hypercholesterolaemia, hypertriglyceridaemia and transient hyperglycaemia were subsequently confirmed. Treatment for hyperlipidaemia and xanthomas with a low-fat diet (Hill's Feline r/d) and the previously unreported treatment for feline demodicosis of daily oral milbemycin were commenced. Multiple pink, alopecic plaques and papules gradually regressed, however pruritus recurred if immunosuppressive treatment was reduced, and well-demarcated areas of alopecia developed on the head, limbs and trunk, despite negative skin scrapings for demodex mites. Fungal culture of hair samples yielded Microsporum canis. All cutaneous lesions resolved with the addition of griseofulvin to the treatment regimen. Concurrent corneal ulceration and keratoconjunctivitis sicca ultimately resolved with treatment, including topical cyclosporin. Diabetes mellitus developed 6 months after resolution of skin lesions. No cutaneous or ocular abnormalities were present 6 months later with continued low-fat diet and insulin administration, although transient recurrence of papules and pruritus occurred after inadvertent access to a fatty meal. An underlying primary hyperlipidaemia was suspected, causing pruritic xanthomas. This may represent the first report of concurrent cutaneous xanthomas, demodicosis and dermatophytosis in a cat.

    We examined the extent to which retrospective proxy reports of well-being mirror participant self-reports at 12-24 months before death and how proxy reports of well-being change over the last year of life. We also explored the role of sociodemographic, cognitive, and health factors of both participants and proxies in moderating such associations. We used retrospective proxy ratings obtained in the German Socio-Economic Panel Study (N = 164; age at death = 19-99 years). Results revealed moderate agreement between self- and proxy reports (r = .42), but proxies, on average, overestimated participants' life satisfaction by two thirds of a scale point on a 0-10 scale (or 0.4 SD). Discrepancies were particularly pronounced when proxies themselves reported low life satisfaction. Over the last year of life, participants were viewed to have experienced declines in life satisfaction (-0.54 SD). Declines were stronger for ill participants and proxies who reported low life satisfaction. Results qualify theoretical expectations and empirical results based on self-report data that are typically available 1 or 2 years before death. We discuss that retrospective proxy reports in panel surveys can be used as a hypothesis-generating tool to gather insights into late life. © The Author 2013.

  11. Synchronous GISTs associated with multiple sporadic tumors: a case report

    Directory of Open Access Journals (Sweden)

    2017-08-01

    Full Text Available Gastrointestinal stromal tumors (GISTs are rare neoplasms, but they also represent the most common mesenchymal tumors of the gastrointestinal tract originating from the cell of Cajal. GIST incidence ranges around 1% of all gastrointestinal malignancies. Approximately 5% of all GISTs have a hereditary etiology. The remaining 95% of GISTs are considered sporadic events, with up to 75% of cases driven by a constitutional activation of the c-KIT proto-oncogene. GISTs are generally solitary lesions. Nonetheless, multiple sporadic GISTs can occur and present as synchronous or metachronous tumors, usually associated with familial GIST. Here, we report a case of primary prostate and lung tumors associated with gastric and small bowel GISTs, unrelated to any known hereditary syndrome. Also, in the case we describe, the prostatic tumor came before the GISTs, while the lung tumor occurred later in time and led to pulmonary lobectomy plus lymphoadenectomy, with a diagnosis of nonsmall cell lung cancer. With the exception of a slight difference in lymphoid infiltration, the abdominal and gastric GIST nodules shared the same proliferative MIB1 index and mitotic count. However, the genetic analysis revealed that the gastric GIST and abdominal tumors were characterized by two different c-KIT mutations. This molecular heterogeneity supported the hypothesis of two different synchronous GISTs arising from stomach and ileum. At present, the patient is disease free and has already completed the third year of adjuvant therapy with imatinib. This case supports the importance of the analysis of c-KIT mutational status to distinguish metastases from synchronous multicentric GISTs, with relevant implications in therapeutic decisions, as well as the importance of a dedicated multidisciplinary team and of a radiological follow-up after the diagnosis of a primary GIST, to discover a relapse of the GIST or, possibly, additional malignancies.

    Malnutrition (undernutrition and overnutrition) is a major public health problem in Ghana -affecting growth and development of individuals and the nation. Stunting and overweight are of particular interest, as recent national surveys show a rising trend of overnutrition and stubbornly high burden of stunting among Ghanaian children. There are currently no data on the simultaneous occurrence of overweight and stunting within individuals in Ghana. This paper presents the burden, the individual-level, and contextual determinants of overweight with concurrent stunting among Ghanaian children. This study analyzed data set of the fourth round of the Ghana Multiple Indicator Cluster Survey (MICS4). Bivariate analyses were used to describe selected characteristics of survey respondents and their children. Hierarchical modelling approach facilitated identification of significant distal, intermediate and proximal factors/determinants of concurrent stunting and overweight. Both crude and adjusted prevalence ratios via a multivariable Poison regression model with their corresponding 95% Confidence Intervals (CI) are reported. Variables with p ≤ 0.25 at the bivariate level were included in the multivariable analysis. An alpha value of 5% was used to indicate significance. Of 7550 cases (children) analyzed, the prevalence of stunting was 27.5%; underweight was 17.3%; and wasting was 7.7%. The prevalence of overweight and concurrent overweight and stunting were respectively 2.4% and 1.2%. Children who belonged to the fourth wealth quintile, were more likely to be overweight and concurrently stunted as against children belonging to the poorest quintile (aPR = 1.010; 95% CI, 1.003-1.017). Compared to religious (Christians/Muslim/Traditionalist) household heads, children whose household heads did not belong to any religion had 2 times the rates of the Overweight with concurrent stunting (PR = 2.024; 95% CI, 1.016-4.034). Children with mothers aged 20-34 and 35-49 had an

    2010-01-01

    @@ Introduction Carcinomas of the stomach are the most common malignant tumors in China. Due to the recent developments in diagnostic techniques and instrumentation, the early detection of gastric carcinoma (GC) has increased. Yet synchronous multiple primary gastric carcinomas, de-fined as 2 or more primary gastric carcinomas occurring in 1 patient simultaneously, are not frequently seen. The etiology of synchronous tumors is still unclear, and their coexistence can be problematic for surgeons, oncologists and pathologists in regards to diagnosis, treat-ment, and follow-up. Research has focused mainly on such issues as the frequency of occurrence of primary multiple carcinomas, identi-fication of high-risk groups, early diagnosis, treatment methods, and prognostic factors. The purpose of this article is to present a rare case of synchronous tumors and to review the literature addressing the sur-gical treatment for patients with multiple cancers.

    We present the case of a 70-year-old man diagnosed with multiple myeloma in 2008, who after four therapy lines initiated a fifth-line treatment with pomalidomide (4 mg orally, days 1-21 of a 28-day cycle) and low-dose dexamethasone (40 mg weekly orally). The patient was treated with pomalidomide for almost 2 years achieving a complete remission after 12 cycles. Complete remission was maintained for 9 months. This case illustrates the potential of pomalidomide plus low-dose dexamethasone to overcome multiple myeloma refractoriness inducing a quick and very prolonged remission.

    Full Text Available A 2-year-old cat was presented with generalised muscle tremors and progressive fore- and hindlimb ataxia, 5 months after the initiation of chemotherapy for thymic lymphoma. The lymphoma was treated with combination chemotherapy (cyclophosphamide, vincristine and prednisolone, which resulted in remission. The neurological signs progressed to paralysis and the cat subsequently died. On autopsy, multiple meningiomas were diagnosed, which is an unusual finding. It is possible that the lymphoma chemotherapy resulted in the development of the multiple meningiomas as secondary malignancies.

    Myeloid sarcoma manifesting as multiple lymphadenopathy is quite rare. We present here a case of myeloid sarcoma that first presented with palpable bilateral neck masses. A 53-year-old woman complained about repetitive swelling in the right infraauricular and submental areas for 3 years. The results of computed tomography showed multiple lymphadenopathy in both areas of the neck as well as other parts of the body. So, the presumptive diagnosis was lymphoma, but the result of the excisional biopsy of the neck mass confirmed it to be a myeloid sarcoma.

    2017-01-01

    Verrucous hemangioma is an uncommon congenital vascular malformation, which may clinically masquerade angiokeratoma, lymphangioma circumscriptum, or malignant melanoma. Differentiation is essential owing to varied therapeutic and prognostic implications. We present a rare case of multiple verrucous hemangiomas in a teenage girl who presented with multiple warty lesions over the dorsal aspect of the left foot since birth. Magnetic resonance imaging (MRI) scan was suggestive of a vascular malformation, and skin biopsy showed ectatic blood vessels extending from the papillary dermis into the subcutaneous tissue, diagnostic of verrucous hemangioma. A combination of 0.05% halobetasol propionate with 3% salicylic acid ointment was advised. This therapeutic intervention resulted in significant resolution of the warty lesions over a period of 2 months, following which surgical excision was performed. The implication is that we can use a combination of super potent topical steroid with salicylic acid as an adjunct to surgical resection.

    Seismic data from two explosions was processed using the Systems Science and Software MARS (Multiple Arrival Recognition System) seismic event detector in an effort to determine their relative spatial and temporal separation on the basis of seismic data alone. The explosions were less than 1.0 kilometer apart and were separated by less than 0.5 sec in origin times. The seismic data consisted of nine local accelerograms (r < 1.0 km) and four regional (240 through 400 km) seismograms. The MARS processing clearly indicates the presence of multiple explosions, but the restricted frequency range of the data inhibits accurate time picks and hence limits the precision of the event location.

We show how to use our model to verify a number...... of interesting program transformations that rely on effect annotations. In particular, we prove a Parallelization Theorem, which expresses when it is sound to run two expressions in parallel instead of sequentially. The conditions are expressed solely in terms of the types and effects of the expressions.......

    We show in this article that some concepts from homotopy theory, in algebraic topology,are relevant for studying concurrent programs. We exhibit a natural semantics of semaphore programs, based on partially ordered topological spaces, which are studied up to “elastic deformation” or homotopy......, giving information about important properties of the program, such as deadlocks, unreachables, serializability, essential schedules, etc. In fact, it is not quite ordinary homotopy that has to be used, but rather a “directed homotopy” that does not reverse the flow of time. We show some of the essential...... differences between ordinary and directed homotopy through examples. We also relate the topological view to a combinatorial view of concurrent programs closer to transition systems, through the notion of a cubical set. Finally we apply some of these concepts to the proof of the safeness of a two...

    2016-01-01

    A 46-year-old Chinese woman was admitted to our hospital because of presence of space-occupying lesions in the liver for 2 months in April, 2015. She had a family history of multiple endocrine neoplasia type 1 (MEN1) and physical examination is unremarkable. Previously, she has performed surgery for primary pituitary tumor in 2002 and radiosurgery for its recurrence. Around December 2014, she suffered from abdominal discomfort associated with regurgitation and gastroscopy revealed “gastroduodenal ulcers”, along with elevated gastrin. Next, both magnetic resonance and computed tomography imaging showed multiple intrahepatic lesions, the PET-CT unveiled uptake pattern of 18F-FDG in duodenum and multiple intrahepatic lesions, resembling the appearance of metastatic gastrinoma. The octreotide scan gave identical results. The parathyroid SPECT scans showed abnormal concentrations of radioactivity in right parathyroid. She also had an elevated serum chromogranin A (CgA) level. There was medical evidence to show that she is metastatic MEN1. Although multiple liver metastases, they were considered to be resectable after MDT consultation. The intraoperative exploration found a 1.5 cm tumor on the surface of the tail of the pancreas, a 12 cm retroperitoneal lipoma and two liver metastases, sized 3.5 cm and 1.5 cm, respectively. All these tumors were completely removed. For pancreatic tumor, pathological findings met the diagnostic criteria of neuroendocrine tumor (NET) (G2). Immunohistochemistry revealed neuroendocrine areas were diffusely positive for ATRX, DAXX, SSR2, SSR5 and CgA. For lipoma, the FISH results were negative for CDK4 and MDM2 genes. Postoperatively, adjuvant therapy with octreotide was applied. This case suggested that, as for metastatic gastrinoma, a potentially curative surgical debulking should be considered when a resection of complete or more than 90% of metastatic lesions along with the primary site could be achieved, which is helpful to control

    Full Text Available Abstract Introduction Aggressive, recurrent embolisms require accurate etiologic diagnosis. We describe the case of a 69-year-old Italian Caucasian woman with recurrent arterial embolisms in whom several sources and triggers of thrombosis were detected. Case presentation The patient, a 69-year-old Italian Caucasian woman, presented with a systemic embolism that was initially attributed to atrial fibrillation. The recurrence of embolisms despite anti-thrombotic therapy prompted a re-evaluation of the clinical presentation. New potential causes of thrombosis emerged in this patient, including thrombocytosis associated with the JAK2 V617F mutation and the very rare mural thrombosis of the descending aorta. A mural thrombus in the pulmonary artery was detected contiguous with the aortic mural thrombosis, raising the possibility of a clinically silent ductus Botalli as the initiating event. The patient was treated with warfarin, aspirin, hydroxyurea, and surgery. Conclusions The diagnosis was achieved via systematic use of imaging procedures and reconsideration of blood tests performed to explore the diagnosis of thrombosis. This allowed a deeper and more detailed analysis of the case beyond the conventional approach, which would have aimed to identify one cause for the condition at hand, in this case, atrial fibrillation. The broader approach that we used resulted in the diagnosis of multiple embolisms from multiple sites and multiple causes.

    Full Text Available Teaching behavior has important implications for students’ emotional well-being. Multiple models suggest students’ perceptions of teaching behaviors are more critical than other measures for predicting well-being, yet student-report instruments that measure concrete and specific teaching behavior are limited. The purpose of the present studies is to develop an instrument to assess students’ perceptions of concrete and specific teaching behavior and to test which teaching behavior is associated students’ well-being. Construct validity and internal consistency for the 37-item Teaching Behavior Questionnaire (TBQ-S, composed of instructional, negative teaching, socioemotional, and organizational behavior were examined using data from two independent samples (Study 1: n = 703; Study 2: n = 822. The factor structure was stable across both samples and internal consistencies ranged from .77 to .97. Results indicated student-ratings of teaching behavior were associated with positive and negative affect in students.

    Case report. To report a case and review the literature on intracranial malignant meningioma with metastasis to the spine. Because so few cases have been recognized and reported, the radiologic and pathologic assessment, pathway of metastasis, and the concepts of surgical resection and other palliative management of this disease are still controversial. A big lobulated mass in the left frontal lobe containing calcifications and tumor bleeding was resected. Pathologic findings indicated malignant meningioma due to bone destruction and dura invasion grossly, and tumor cellular atypism with mitotic activity and massive tumor necrosis microscopically. Radiotherapy followed, and brain computed tomography revealed no definite evidence of recurrence. Three months later, spinal magnetic resonance imaging revealed multiple bone metastasis in lower T-L-S1, and pathologic fracture of L1 with compression of the dural sac and spinal cord. Surgical resection was done for decompression, fixation, and pathologic proof. Both pathologic and immunohistochemical survey found evidence consistent with malignant meningioma with spinal metastasis. Advanced treatment was refused, and the patient died. Spinal magnetic resonance imaging should be performed because of the high spinal metastatic rate, especially when spinal symptoms and signs are present. Immunohistochemical study has an important role in the differential diagnosis of primary or metastatic intracranial neoplasms.

    High-grade (HGG) and diffuse intrinsic pontine gliomas (DIPG) with primary metastatic spread are extremely rare and have a dismal prognosis. Analogous to simultaneous radiochemotherapy in non-metastatic HGG and DIPG, concurrent craniospinal irradiation (CSI) and metronomic temozolomide (metroTMZ) may represent a reasonable therapeutic approach. However, the antitumor efficacy and toxicity of this treatment still have to be investigated. Between March 2007 and December 2012, six children with primary metastatic HGG (n=4) or DIPG (n=2) received CSI and concurrent metroTMZ based on individual treatment recommendations and, in some cases, within the HIT-HGG 2007 multicenter trial. Outcome and treatment-related toxicities were evaluated. All patients received irradiation to the entire craniospinal axis (35.2 Gy, n=5; 36 Gy, n=1:) and 5 received a local boost to macroscopic tumor deposits. Simultaneously, metroTMZ (75 mg/m{sup 2}/day, n=5; 60 mg/m{sup 2}/day, n=1) was administered. Additionally, 1 patient received nimotuzumab once per week. Within a median follow-up of 10.0 months (range 6.5-18.7 months), all patients experienced disease progression and 5 patients died. Median progression-free survival was 4.0±0.8 months (range 2.4-10.7 months) and median overall survival was 7.6±3.5 months (range 4.0-17.6 months). Acute myelosuppression most severely limited application of this aggressive treatment strategy. Severe hematotoxicities (= grade 3) occurred in all patients and metroTMZ had to be interrupted or discontinued in 4 out of 6 cases. Concurrent CSI and metroTMZ might represent a feasible treatment approach for primary metastatic HGG and DIPG. On the basis of our experience, severe but manageable acute hematotoxicity has to be expected. An international effort is warranted to reassess the efficacy and toxicity of this approach within a prospective study. (orig.)

    Dentinogenesis imperfecta (DGI) is a hereditary defect consisting of opalescent teeth composed of irregularly formed and hypomineralized dentin. This paper presents the multiple fractures of DGI-affected teeth and suggests the reason of low fracture resistance by observing the dentin microstructures directly using scanning electron microscope (SEM) and by measuring its surface hardness using the Vickers hardness test. SEM revealed that while the enamel microstructure was similar in the DGI-affected and normal teeth, the microstructure of the DGI-affected dentin was poorly woven and more loosely packed than that of the normal dentin. The Vickers hardness of the DGI-affected dentin was 4.89 times softer than the normal dentin. The low fracture resistance of DGI-affected teeth can be attributed to the poorly woven microstructure of their dentin, which leads to a reduction in hardness.

    We describe the case of a female patient who, at the age of 28, was diagnosed with symptoms of primary progressive multiple sclerosis (PPMS). Glucocorticoid treatment was immediately initiated. The disease and the demyelinating lesions progressed during the following 9 years reaching Expanded Disability Status Scale (EDSS) 8.0 (patient essentially restricted to bed, a chair or perambulated in a wheelchair). At this point, the patient began taking melatonin at doses ranging from 50 to 300 mg per day. Melatonin was her only treatment for the next 4 years; during this interval, her EDSS progressively recovered to 6.0 (the person needs intermittent or unilateral constant assistance such as cane, crutch, or brace to walk 100 meters with or without resting). This long-lasting improvement is likely due to melatonin usage since it is related in time and because of its exceptionally long duration.

    2011-06-01

    The PreNotiS (preventive notification system) was proposed to address the current lack in consumer prevention and disaster informatics systems. The underscore of this letter is to propose PreNotiS as a provision of trusted proxies of information sourcing to be integral to the disaster informatics framework. To promote loose coupling among subsystems, PreNotiS has evolved into a model-view-controller (MVC) architecture via object-oriented incremental prototyping. The MVC specifies how all subsystems and how they interact with each other. A testing framework is also proposed for the PreNotiS to verify multiple concurrent user access which might be observable during disasters. The framework relies on conceptually similar self-test modules to help with serviceability.

This is the main difference with standard...... topological reasoning in which there is no information about relation "in time" among points. The main task is to define equivalence of paths reflecting execution of a program. We use the notion of homotopy history equivalence relation. The model space considered in this work is a differentiable manifold...

    Acupuncture has been widely used in alternative medicine for pain relief but may have many complications due to lack of appropriate cares. Pharmacopuncture is a sort of acupuncture that injects a herbal ingredient through a thin tube for the purpose of combining the effects of the herb and acupuncture and it has many pitfalls. The agents used in pharmacopuncture are not refined for a desired effect and not produced by sterile standard processes under strict medical surveillance. We report a c...

    Full Text Available Embryonic neuroepithelia and adult subventricular zone (SVZ stem and progenitor cells express nestin. We characterized a transgenic line that expresses enhanced green fluorescent protein (eGFP specified to neural tissue by the second intronic enhancer of the nestin promoter that had several novel features. During embryogenesis, the dorsal telencephalon contained many and the ventral telencephalon few eGFP+ cells. eGFP+ cells were found in postnatal and adult neurogenic regions. eGFP+ cells in the SVZ expressed multiple phenotype markers, glial fibrillary acidic protein, Dlx, and neuroblast-specific molecules suggesting the transgene is expressed through the lineage. eGFP+ cell numbers increased in the SVZ after cortical injury, suggesting this line will be useful in probing postinjury neurogenesis. In non-neurogenic regions, eGFP was strongly expressed in oligodendrocyte progenitors, but not in astrocytes, even when they were reactive. This eGFP+ mouse will facilitate studies of proliferative neuroepithelia and adult neurogenesis, as well as of parenchymal oligodendrocytes.

  11. Recursive Concurrent Stochastic Games

    2008-01-01

    We study Recursive Concurrent Stochastic Games (RCSGs), extending our recent analysis of recursive simple stochastic games [16,17] to a concurrent setting where the two players choose moves simultaneously and independently at each state. For multi-exit games, our earlier work already showed undecidability for basic questions like termination, thus we focus on the important case of single-exit RCSGs (1-RCSGs). We first characterize the value of a 1-RCSG termination game as the least fixed point solution of a system of nonlinear minimax functional equations, and use it to show PSPACE decidability for the quantitative termination problem. We then give a strategy improvement technique, which we use to show that player 1 (maximizer) has \\epsilon-optimal randomized Stackless & Memoryless (r-SM) strategies for all \\epsilon > 0, while player 2 (minimizer) has optimal r-SM strategies. Thus, such games are r-SM-determined. These results mirror and generalize in a strong sense the randomized memoryless determinacy r...

    Fibromyxoma of the jaw is a rare benign mesenchymal odontogenic tumor with locally aggressive behavior. In the present report, a 13-year-old female patient presented to our university hospital with delayed eruption of some of her teeth. A panoramic radiograph taken at the initial examination revealed four pericoronal radiolucencies related to the four third molars. Thereafter, a magnetic resonance imaging (MRI) examination was performed. After the surgical removal of these molars, the microscopic examination diagnosed the four lesions as fibromyxomas. Here, we have discussed the clinical, panoramic radiography, MRI, and histopathological findings of the case.

    2016-08-01

    The ability to isolate a single sound source among concurrent sources is crucial for veridical auditory perception. The present study investigated the event-related oscillations evoked by complex tones, which could be perceived as a single sound and tonal complexes with cues promoting the perception of two concurrent sounds by inharmonicity, onset asynchrony, and/or perceived source location difference of the components tones. In separate task conditions, participants performed a visual change detection task (visual control), watched a silent movie (passive listening) or reported for each tone whether they perceived one or two concurrent sounds (active listening). In two time windows, the amplitude of theta oscillation was modulated by the presence vs. absence of the cues: 60-350ms/6-8Hz (early) and 350-450ms/4-8Hz (late). The early response appeared both in the passive and the active listening conditions; it did not closely match the task performance; and it had a fronto-central scalp distribution. The late response was only elicited in the active listening condition; it closely matched the task performance; and it had a centro-parietal scalp distribution. The neural processes reflected by these responses are probably involved in the processing of concurrent sound segregation cues, in sound categorization, and response preparation and monitoring. The current results are compatible with the notion that theta oscillations mediate some of the processes involved in concurrent sound segregation.

    Full Text Available Background. Undiagnosed intracranial hypotension can result in several complications including subdural hematoma (SDH, subarachnoid hemorrhage (SAH, dural venous sinuses thrombosis (CVT, cranial nerve palsies, and stupor resulting from sagging of the brain. It is rare to see all the complications in one patient. Furthermore, imaging of the brain vasculature may reveal incidental asymptomatic small aneurysms. Given the combination of these imaging findings and a severe headache, the patients are often confused to have a primary subarachnoid hemorrhage. Case Report. We present a patient with spontaneous intracranial hypotension (SIH who had an incidental ophthalmic artery aneurysm on MR imaging, and this presentation led to coiling of the aneurysm. The key aspect in the history “postural headaches” was missed, and this led to life threatening complications and unnecessary interventions. Revisiting the history and significant improvement in symptoms following an epidural blood patch resulted in the diagnosis of SIH. Conclusion. We strongly emphasize that appropriate history taking is the key in the diagnosis of SIH and providing timely treatment with an epidural blood patch could prevent potentially life threatening complications.

  4. Concurrent Quantum Computation

    CERN Document Server

    Yamaguchi, F; Yamamoto, Y

    2000-01-01

    A quantum computer is a multi-particle interferometer that comprises beam splitters at both ends and arms, where the n two-level particles undergo the interactions among them. The arms are designed so that relevant functions required to produce a computational result is stored in the phase shifts of the 2^n arms. They can be detected by interferometry that allows us to utilize quantum parallelism. Quantum algorithms are accountable for what interferometers to be constructed to compute particular problems. A standard formalism for constructing the arms has been developed by the extension of classical reversible gate arrays. By its nature of sequential applications of logic operations, the required number of gates increases exponentially as the problem size grows. This may cause a crucial obstacle to perform a quantum computation within a limited decoherence time. We propose a direct and concurrent construction of the interferometer arms by one-time evolution of a physical system with arbitrary multi-particle i...

    Aplastic anemia (AA) patients with prolonged immunosuppression have a risk of development of lymphoproliferative disorders (LPDs), especially combined with Epstein-Barr virus (EBV) infection. However, development of nature killer/T (NK/T) cell lymphoma, in a nontransplantation setting, has not been documented for AA patients with immunosuppressive therapy (IST). Herein, we described a middle-aged man, Han ethnic, who presented with swelled parotid gland after a long history of IST for AA. Fever, night sweating, weight loss had not been found. Increased heterotypic lymphocytes had been detected in the left side of parotid gland demonstrated as cCD3(+), CD56(+), GranB(+), TIA-1(+), MUM-1(+), KI-67 (50%-75%)(++), Bcl-6(-), MPO(-) by immunohistochemistry, and in-situ hybridization (ISH) indicated EBER positive. Chromosome analysis by R banding method revealed 46, XY [20]. NK/T cell lymphoma concurrent with aplastic anemia was diagnosed and a mild chemotherapy regimen including vincristine, prednisone, L-asparaginase was administered. The parotid mass was gradually regressed after the first cycle of chemotherapy. The patient discharged from the hospital voluntarily and lost the follow-up.

    1987-01-01

    This article is the first of a two-part series which argues for the concurrent management of the appropriateness, necessity, and quality of patient care. Intensifying scrutiny by the credentialing groups, the PROs and all third-party payors underscores the vital need to implement cost-effective information systems which integrate the departmentalized functions of patient-physician profiling, DRG case-mix analyses, length of stay monitoring, pre-admission/admission and continued stay review, discharge planning, risk management, incident reporting and quality review. In the domain of physician performance regarding admitting and practice patterns, the ability to exercise concurrent utilization-quality review means early detection and prevention of events which would otherwise result in denials of payment and/or compromised patient care. Concurrent utilization-quality review must, by definition, be managerially invasive and focused; hence, it is integral to maintaining the integrity of the services and product lines offered by the provider. In fact, if PPO status is a marketing agenda, then the institutional objectives of cost-effectiveness, productivity, value, and competitiveness can only be achieved through concurrent utilization-quality review.

    An imbalance in tryptophan (TRP) metabolites is associated with several neurological and inflammatory disorders. Therefore, analytical methods allowing for simultaneous quantification of TRP and its major metabolites would be highly desirable, and may be valuable as potential biomarkers. We have developed a HPLC method for concurrent quantitative determination of tryptophan, serotonin, 5-hydroxyindoleacetic acid, kynurenine, and kynurenic acid in tissue and fluids. The method utilizes the intrinsic spectroscopic properties of TRP and its metabolites that enable UV absorbance and fluorescence detection by HPLC, without additional labeling. The origin of the peaks related to analytes of interest was confirmed by UV–Vis spectral patterns using a PDA detector and mass spectrometry. The developed methods were validated in rabbit fetal brain and amniotic fluid at gestational day 29. Results are in excellent agreement with those reported in the literature for the same regions. This method allows for rapid quantification of tryptophan and four of its major metabolites concurrently. A change in the relative ratios of these metabolites can provide important insights in predicting the presence and progression of neuroinflammation in disorders such as cerebral palsy, autism, multiple sclerosis, Alzheimer disease, and schizophrenia.

    HEP experiments produce enormous data sets at an ever-growing rate. To cope with the challenge posed by these data sets, experiments’ software needs to embrace all capabilities modern CPUs offer. With decreasing memory/core ratio, the one-process-per-core approach of recent years becomes less feasible. Instead, multi-threading with fine-grained parallelism needs to be exploited to benefit from memory sharing among threads. Gaudi is an experiment-independent data processing framework, used for instance by the ATLAS and LHCbexperiments at CERN's Large Hadron Collider. It has originally been designed with only sequential processing in mind. In a recent effort, the frame work has been extended to allow for multi-threaded processing. This includes components for concurrent scheduling of several algorithms - either processingthe same or multiple events, thread-safe data store access and resource management. In the sequential case, the relationships between algorithms are encoded implicitly in their pre-determined execution order. For parallel processing, these relationships need to be expressed explicitly, in order for the scheduler to be able to exploit maximum parallelism while respecting dependencies between algorithms. Therefore, means to express and automatically track these dependencies need to be provided by the framework. In this paper, we present components introduced to express and track dependencies of algorithms to deduce a precedence-constrained directed acyclic graph, which serves as basis for our algorithmically sophisticated scheduling approach for tasks with dynamic priorities. We introduce an incremental migration path for existing experiments towards parallel processing and highlight the benefits of explicit dependencies even in the sequential case, such as sanity checks and sequence optimization by graph analysis.

    Written by a team of two leading experts and two very successful young former PhD students, New Methods of Concurrent Checking describes new methods of concurrent checking, such as partial duplication, use of output dependencies, complementary circuits, self-dual parity, self-dual duplication and others. A special chapter demonstrates how the new general methods of concurrent checking can be more specifically applied to regular structures to obtain optimum results. This is exemplified for all types of adders up to 64 bits with a level of detail never before presented in the literature. The cle

    The proliferation of shared mutable state in object-oriented programming complicates software development as two seemingly unrelated operations may interact via an alias and produce unexpected results. In concurrent programming this manifests itself as data-races. Concurrent object-oriented programming further suffers from the fact that code that warrants synchronisation cannot easily be distinguished from code that does not. The burden is placed solely on the programmer to reason ab...

    This communication reports invasive amoebic colitis and late onset amoebic liver abscess in three members of a group of 12 Australian travellers to Timor-Leste (TL). This is the first report of Entamoeba histolytica infection from TL. Clinicians in Australia need to consider amoebiasis in the differential diagnosis in travellers returning with colitis, abdominal pain and fever. Presentation with amoebic liver abscess months after exposure is rare but should be suspected in symptomatic individuals with a relevant history of travel.

    Full Text Available Abstract Background Co-circulation of multiple dengue virus serotypes has been reported from many parts of the world including India, however concurrent infection with more than one serotype of dengue viruses in the same individual is rarely documented. An outbreak of dengue hemorrhagic fever/dengue shock syndrome (DHF/DSS occurred in and around Delhi in 2006. This is the first report from India with high percentage of concurrent infections with different dengue virus serotypes circulating during one outbreak. Results Acute phase sera from patients were tested for the presence of dengue virus RNA by RT-PCR assay. Of the 69 samples tested for dengue virus RNA, 48 (69.5% were found to be positive. All the four dengue virus serotypes were found to be co-circulating in this outbreak with DENV-3 being the predominant serotype. In addition in 9 of 48 (19% dengue virus positive samples, concurrent infection with more than one dengue virus serotype were identified. Conclusion This is the first report in which concurrent infections with different dengue virus serotypes is being reported during an outbreak from India. Delhi is now truly hyperendemic for dengue.

    2007-05-01

    Multiple spinal extradural meningeal cysts are rare. To the authors' knowledge, there have been only four reported cases in the world literature. The authors report a case of multiple spinal extradural meningeal cysts in a 31-year-old woman presenting with acute paraplegia. Magnetic resonance imaging of the thoracolumbar spine revealed multiple extradural cystic lesions extending from T-7 to T-8 and from T-12 to L-3. Intraoperative findings demonstrated a white, fibrous, and tense cyst filled with cerebrospinal fluid-like colorless fluid. Excision of the posterior wall of the symptomatic cyst was followed by immediate neurological improvement. The examination of the pathological specimen showed a thick duralike layer of collagen and an inner membrane of arachnoid that is often not found in these lesions. The final diagnosis was based on combined imaging, intraoperative, and histopathological findings. The authors review the literature and discuss the etiological, diagnostic, and therapeutic aspects of this lesion.

    Traumatic brain injuries (TBI) sustained in combat frequently co-occur with significant bodily injuries. Intuitively, more extensive bodily injuries might be associated with increased symptom reporting. In 2012, however, French et al. demonstrated an inverse relation between bodily injury severity and symptom reporting. This study expands on that work by examining the influence of location and severity of bodily injuries on symptom reporting after mild TBI. Participants were 579 US military service members who sustained an uncomplicated mild TBI with concurrent bodily injuries and who were evaluated at two military medical centers. Bodily injury severity was quantified using a modified Injury Severity Score (ISSmod). Participants completed the Neurobehavioral Symptom Inventory (NSI) and the Posttraumatic Stress Disorder Checklist (PCL-C), on average, 2.5 months post-injury. There was a significant negative association between ISSmod scores and NSI (r=-0.267, pinverse relation between bodily injury severity and symptom reporting in this sample. Hypothesized explanations include underreporting of symptoms, increased peer support, disruption of fear conditioning because of acute morphine use, or delayed expression of symptoms.

  1. Concurrent negotiation and coordination for grid resource coallocation.

    2010-06-01

    Bolstering resource coallocation is essential for realizing the Grid vision, because computationally intensive applications often require multiple computing resources from different administrative domains. Given that resource providers and consumers may have different requirements, successfully obtaining commitments through concurrent negotiations with multiple resource providers to simultaneously access several resources is a very challenging task for consumers. The impetus of this paper is that it is one of the earliest works that consider a concurrent negotiation mechanism for Grid resource coallocation. The concurrent negotiation mechanism is designed for 1) managing (de)commitment of contracts through one-to-many negotiations and 2) coordination of multiple concurrent one-to-many negotiations between a consumer and multiple resource providers. The novel contributions of this paper are devising 1) a utility-oriented coordination (UOC) strategy, 2) three classes of commitment management strategies (CMSs) for concurrent negotiation, and 3) the negotiation protocols of consumers and providers. Implementing these ideas in a testbed, three series of experiments were carried out in a variety of settings to compare the following: 1) the CMSs in this paper with the work of others in a single one-to-many negotiation environment for one resource where decommitment is allowed for both provider and consumer agents; 2) the performance of the three classes of CMSs in different resource market types; and 3) the UOC strategy with the work of others [e.g., the patient coordination strategy (PCS )] for coordinating multiple concurrent negotiations. Empirical results show the following: 1) the UOC strategy achieved higher utility, faster negotiation speed, and higher success rates than PCS for different resource market types; and 2) the CMS in this paper achieved higher final utility than the CMS in other works. Additionally, the properties of the three classes of CMSs in

    Patients with relapsed and refractory multiple myeloma have poor prognosis. A recent analysis of patients with relapsed and refractory multiple myeloma who were refractory to both proteasome inhibitors and immunomodulatory drugs showed the median overall survival of 9 months only. Daratumumab is the first-in-class human monoclonal antibody against CD38 cells which was studied in phase I/II trials for treatment of these patients with relapsed refractory multiple myeloma. It showed an overall response rate of 36% and a median overall survival (OS) of 17 months in these patients. We report a case of 40-year-old man with immunoglobulin D (IgD) multiple myeloma whose disease was refractory to at least 5 different chemotherapy regimens including proteasome inhibitors and immunomodulatory drugs. The clinical studies assessing daratumumab did not include any patients with IgD myeloma which is a rare form of multiple myeloma and to our knowledge is the first study reporting use of daratumumab in IgD myeloma.

    Chromoblastomycosis and Madura foot are chronic localised mycotic infection of the skin and subcutaneous tissue that follows the implantation of the fungi through minor trauma, mainly found in persons working outdoors on bare foot. In cases where both Madura and chromoblastomycosis are present, the treatment becomes difficult with low cure rates and frequent relapses. Here, we present such a very rare case of a 38-year-old cattle farmer who presented with verrucose nodules, tumefaction and multiple discharging nodules on the left lower 1/3 rd leg and foot since last 9 years. Direct KOH mount of the verrucose tissue showed Fonsecaea pedrosoi sclerotic muriform bodies and a biopsy of one granule discharging nodule demonstrated fungal mycetoma. He was put on tab. Itraconazole 200 mg o.d. and cotrimoxazole bid for 6 months with very little improvement. The rarity of this combination is most probably due to different geographical distribution.

    Full Text Available Squamous cell ovarian and sigmoid colon carcinomas are extremely rare malignancies. Because of their rarity, it is difficult to investigate the clinical characteristics and prognosis of patients with theses malignancies, and therefore, the increased interest in each clinical case report is highly relevant. Multiple primary squamous cell ovarian and sigmoid colon carcinomas are the subject of discussion and differential diagnosis of sigmoid colon cancer with secondary ovarian cancer. Histopathological and clinical characteristics of the tumors were present and evidences in favor of the multiple primary malignancies were given. The association of squamous cell ovarian and sigmoid colon carcinomas with human papilloma virus type 16 was shown.

    Full Text Available Supernumerary teeth are the teeth present in addition to the normal set of teeth and are not uncommon in the general population. Presence of supernumerary teeth may affect the aesthetics of an individual and hence need appropriate management. It is however rare to find multiple supernumerary teeth which are not associated with any syndromes. Non-syndromic multiple supernumerary teeth have a predilection to occur in the mandibular premolar region. This paper reports an unusual case of an 18 year old boy with two completely erupted additional premolars on either side of the mandibular arch.

    Full Text Available To our knowledge, the occurrence of multiple mucoceles is not very common. This case report presents a 62-year-old man with multiple nodules on the upper and lower labial mucosa as well as both buccal mucosae with unknown history. Histopathology evaluation showed minor salivary gland ducts dilated to the point of cyst formation. The cysts seemed to be formed either as a result of dilatation of salivary ducts due to altered secretion or because of an acquired or congenital weakness in the ductal structure. The physiopathology of these findings is discussed.

    Abstract Background: Kimura disease is a rare chronic inflammatory disorder with peripheral eosinophilia and elevated serum IgE and is also frequently complicated by nephropathy. Methods: We report a rare case of Kimura disease concomitant with lupus nephritis in a 72-year old male patient with recurrent unexplained lymphadenopathy, renal lesions, and immunologic abnormalities. Results: The patient was successfully managed with gamma immunoglobulin, intravenous pulse methylprednisolone therapy, hydroxychloroquine, and prednisone. Conclusion: This is the first report of a case of Kimura disease concomitant with lupus nephritis and highlights the importance of considering lupus nephritis as a possible concurrent disease in patients with Kimura disease that have immunologic abnormalities.

    2009-03-01

    Full Text Available Abstract Background Reporter gene mice are valuable animal models for biological research providing a gene expression readout that can contribute to cellular characterization within the context of a developmental process. With the advancement of bacterial recombination techniques to engineer reporter gene constructs from BAC genomic clones and the generation of optically distinguishable fluorescent protein reporter genes, there is an unprecedented capability to engineer more informative transgenic reporter mouse models relative to what has been traditionally available. Results We demonstrate here our first effort on the development of a three stage bacterial recombination strategy to physically link multiple genes together with their respective fluorescent protein (FP reporters in one DNA fragment. This strategy uses bacterial recombination techniques to: (1 subclone genes of interest into BAC linking vectors, (2 insert desired reporter genes into respective genes and (3 link different gene-reporters together. As proof of concept, we have generated a single DNA fragment containing the genes Trap, Dmp1, and Ibsp driving the expression of ECFP, mCherry, and Topaz FP reporter genes, respectively. Using this DNA construct, we have successfully generated transgenic reporter mice that retain two to three gene readouts. Conclusion The three stage methodology to link multiple genes with their respective fluorescent protein reporter works with reasonable efficiency. Moreover, gene linkage allows for their common chromosomal integration into a single locus. However, the testing of this multi-reporter DNA construct by transgenesis does suggest that the linkage of two different genes together, despite their large size, can still create a positional effect. We believe that gene choice, genomic DNA fragment size and the presence of endogenous insulator elements are critical variables.

    2015-01-01

    Reward reactivity and positive emotion are key components of a theoretical, early-emerging approach motivational system, yet few studies have examined associations between positive emotion and neural reactivity to reward across development. In this multi-method prospective study, we examined the association of laboratory observations of positive emotionality (PE) at age 3 and self-reported positive affect (PA) at age 9 with an event-related potential component sensitive to the relative response to winning vs. losing money, the feedback negativity (ΔFN), at age 9 (N=381). Males had a larger ΔFN than females, and both greater observed PE at age 3 and self-reported PA at age 9 significantly, but modestly, predicted an enhanced ΔFN at age 9. Negative emotionality and behavioral inhibition did not predict ΔFN. Results contribute to understanding the neural correlates of PE and suggest that the FN and PE may be related to the same biobehavioral approach system.

    The Vaccine Adverse Event Reporting System (VAERS), administered by the FDA and CDC, is the U.S. system for surveillance of vaccine adverse events (AE). Acute encephalopathy age or =18 months (EO > or = 18), encephalitis (EI), and multiple sclerosis (MS) after vaccination have been reported to VAERS, but reports often contain insufficient information to validate diagnoses. Standardized case definitions would enhance the utility of VAERS reports for AE surveillance. We developed practical case definitions for classification of VAERS reports, and three neurologists independently applied the definitions to reports submitted in 1993. Inter-observer agreement was assessed, and non-concordant classifications were reviewed in a follow-up conference call. Reports of EO or = 18 (n = 20), EI (n = 15), and MS (n = 16) were classified as "definite" in 7% to 30% of the cases, while 26% to 51% of reports were thought to have insufficient information to make a classification. Agreement among reviewers was good to excellent, (kappa: 0.65 to 0.85) except for EO Elsevier Science Inc.

    Full Text Available Multiple myeloma (MM is a plasma cell disorder associated with clonal proliferation of plasma cells. Nonsecretory multiple myeloma (NSMM is a rare variant of MM and accounts for approximately 1% to 5% of all cases. It is defined as symptomatic myeloma without detectable monoclonal immunoglobulin on serum or urine electrophoresis. This variant usually poses a diagnostic challenge to the clinician. We present a 60-year-old Nigerian man who was investigated extensively for bone pain, weight loss, and anaemia. He was eventually diagnosed as having nonsecretory multiple myeloma based on histology and immunohistochemistry results of bone marrow trephine biopsy. He is currently being managed with bortezomib, doxorubicin, and thalidomide, as well as zoledronic acid. He is also on anticoagulation. He continues to show remarkable clinical improvement. We describe this case report and literature review for better awareness amongst medical practitioners and pathologists.

    Full Text Available Multiple cerebral tuberculomas complicating miliary tuberculosis are a rare occurrence. It is rarer still for multiple cerebral tuberculomas to present without focal neurological deficits. We report the case of a middle-aged Nigerian male with the co-morbidity of miliary tuberculosis and multiple cerebral tuberculomaswho presented without focal neurological deficits buthad complete resolution of symptoms and signs following a 6-month course of antituberculous therapy. This unique case emphasizes the need for a high index of suspicion in the diagnosis of atypical presentations of cerebral tuberculomas while also further illustrating the place of computed tomographic scan of the brain in diagnosis. The case also illustrates the place of therapeutic trial in management.

    Root resorption is loss of dental hard tissue as a result of clastic activities. The dental hard tissue of permanent teeth does not normally undergo resorption, except in cases of inflammation or trauma. However, there are rare cases of tooth resorption of an unknown cause, known as 'idiopathic root resorption.' This report would discuss a rare case of multiple idiopathic resorption in the permanent maxillary and mandibular teeth of an otherwise healthy 36-year-old male patient. In addition to a clinical examination, the patient was imaged using conventional radiography and cone-beam computed tomography (CBCT). The examinations revealed multiple external and internal resorption of the teeth in all four quadrants of the jaws with an unknown cause. Multiple root resorption is a rare clinical phenomenon that should be examined using different radiographic modalities. Cross-sectional CBCT is useful in the diagnosis and examination of such lesions.

An initial head computed tomography (CT showed sulcal enlargement and ventricular dilatation, but no evidence of ICH. A tap test indicated as a guide to case selection for shunt surgery accidentally resulted in cerebrospinal fluid (CSF overdrainage. The patient presented sudden neurological deterioration, with sluggishly responsive pupils and generalized tonic-clonic seizures. A new head CT demonstrated multiple supra and infratentorial ICH. The patient became comatose and had a fatal course. Hence, CSF overdrainage may either cause or precipitate multiple simultaneous ICHs, affecting both the infratentorial and supratentorial regions.

    A 6-year-old female nulliparous Dutch Rabbit (Oryctolagus cuniculus) was presented in shock status with a history of abdominal distention, inappetance, lethargy, polydipsia, diarrhea and weight loss since 2 weeks ago. There was no breeding history. Radiographic survey showed increased soft tissue opacity dorsal to the urinary bladder and ventral to the colon on the lateral view consistent with uteromegaly and severe intestinal distention resembling intussusceptions. Conservative treatment was failed and the animal died. In necropsy, ileocecal intussusception was noted as the main death factor. Thickened uterine endometrium in both horns was observed and the uterus was filled with mucoid fluid. Both ovaries were multilobulated and distended. On the other hand, a small cyst sized 1.5 × 2.5 cm was diagnosed on the liver surface. Several samples were obtained from lesions for histopathological evaluation. Histopathologically, dilated cystic glands of variable size lined by densely packed epithelium and hyperplasia of the endometrium resulting in irregular folds or papillar projection into the lumen were evident and the sections of ovaries revealed ovarian luteoma that composed of polyhedral cells with pale stained vacuolated cytoplasm, centrally located nuclei with distinct cytoplasmic borders and the cytoplasm of cells contain lipid droplet. The occurrence of biliary cyst adenoma was confirmed by microscopic examination of the mass that composed of multicystic space in different sizes lined by flattened to cuboidal biliary epithelium with papillary projections. These cysts were seperated by variable amount of connective tissue. The lack of postmortem investigations in aged rabbits reduced the incidence of neoplastic disease diagnosis in this species. Whereas uterine adenecarcinoma and lymphosarcoma were commonly reported in rabbits, luteoma and biliary cyst adenoma that are well described in this case report were uncommon in rabbit medicine.

    Research and application of Concurrent Engineering have produced good results. A Chinese style concurrent engineering architecture and reference mode has been produced. A series of break thoughts in BPR (Business Process Reengineering) have been made with organization of the IPT (Integrated Product Development Team) and engineering support technologies. Several prototype tools were developed, including product development process modeling and management, QFD-based schema design and decision making, PDM-based concurrent design, STEP-based CAD/CAPP/CAM integration, design for assembly, design for manufacturing, computer aided fixture design, and machining process simulation. Finally, the research results were used in the development of two complex components in an aerospace application, and satisfactory results were obtained.

  3. STU attractors from vanishing concurrence

    2010-01-01

    Concurrence is an entanglement measure characterizing the {\\it mixed} state bipartite correlations inside of a pure state of an $n$-qubit system. We show that after organizing the charges and the moduli in the STU model of $N=2$, $d=4$ supergravity to a three-qubit state, for static extremal spherically symmetric BPS black hole solutions the vanishing condition for all of the bipartite concurrences on the horizon is equivalent to the attractor equations. As a result of this the macroscopic black hole entropy given by the three-tangle can be reinterpreted as a linear entropy characterizing the {\\it pure} state entanglement for an arbitrary bipartite split. Both for the BPS and non-BPS cases explicit expressions for the concurrences are obtained, with their vanishing on the horizon is demonstrated.

    In order to be able to make effective use of emerging hardware, where the amount of memory available to any CPU is rapidly decreasing as the core count continues to rise, ATLAS has begun a migration to a concurrent, multi-threaded software framework, known as AthenaMT. Significant progress has been made in implementing AthenaMT - we can currently run realistic Geant4 simulations on massively concurrent machines. the migration of realistic prototypes of reconstruction workflows is more difficult, given the large amounts of legacy code and the complexity and challenges of reconstruction software. These types of workflows, however, are the types that will most benefit from the memory reduction features of a multi-threaded framework. One of the challenges that we will report on in this paper is the re-design and implementation of several key asynchronous technologies whose behaviour is radically different in a concurrent environment than in a serial one, namely the management of Conditions data and the Detector D...

  6. Neural Representation of Concurrent Vowels in Macaque Primary Auditory Cortex.

    Successful speech perception in real-world environments requires that the auditory system segregate competing voices that overlap in frequency and time into separate streams. Vowels are major constituents of speech and are comprised of frequencies (harmonics) that are integer multiples of a common fundamental frequency (F0). The pitch and identity of a vowel are determined by its F0 and spectral envelope (formant structure), respectively. When two spectrally overlapping vowels differing in F0 are presented concurrently, they can be readily perceived as two separate "auditory objects" with pitches at their respective F0s. A difference in pitch between two simultaneous vowels provides a powerful cue for their segregation, which in turn, facilitates their individual identification. The neural mechanisms underlying the segregation of concurrent vowels based on pitch differences are poorly understood. Here, we examine neural population responses in macaque primary auditory cortex (A1) to single and double concurrent vowels (/a/ and /i/) that differ in F0 such that they are heard as two separate auditory objects with distinct pitches. We find that neural population responses in A1 can resolve, via a rate-place code, lower harmonics of both single and double concurrent vowels. Furthermore, we show that the formant structures, and hence the identities, of single vowels can be reliably recovered from the neural representation of double concurrent vowels. We conclude that A1 contains sufficient spectral information to enable concurrent vowel segregation and identification by downstream cortical areas.

    The onset of new visual symptoms in patients with multiple sclerosis is often associated with a neuro-ophthalmologic manifestation of the disease. However, other possible differential diagnoses need to be ruled out, including drug-induced retinal side effects. Although uncommon, retinal side effects of interferon-beta formulations may occur, and need to be promptly recognized and treated by neurologists. In this manuscript, we report the case of a 37-year-old woman affected by multiple sclerosis diagnosed with interferon beta-associated retinopathy and we review the literature with regard to the epidemiology, clinical presentation, management and follow-up of interferon beta-associated retinopathy. Interferon-beta induced retinopathy seems to be an uncommon and a dose-related side effect in multiple sclerosis patients. Retinopathy tends to completely resolve after treatment discontinuation. Neurologists must be aware that immune-modulatory drugs, in particular interferon beta, have been reported to cause retinal side effects. In multiple sclerosis patients complaining of new visual symptoms during interferon-beta treatment, it is thus advisable to perform an ophthalmological assessment to rule out and properly manage retinopathy.

    Full Text Available We report the case of a 83-year-old woman suffering from Restless Legs Syndrome since 2002 and Multiple Sclerosis since 2007. She had been diagnosed as Restless Legs Syndrome five years before multiple sclerosis, with the support of a polysomnographic examination. The clinical diagnosis of multiple sclerosis took place at the age of 75, when she complained of walking difficulties and abnormal sensitivity in lower limbs, especially in the evening. Associated symptoms included dysesthesias on the left leg and arm and left emitrunk, visual acuity reduction, blurred vision and fatigue. The brain magnetic resonance showed multiple lesions in white matter, inconsistent with a vascular disease but suggestive for a demyelinating disease. She was admitted at the hospital, where the spinal fluid examination and a second magnetic resonance confirmed the diagnosis. Since that, the patient regularly performed medical examinations and magnetic resonance controls which didn't show any increase of lesions burden nor pathological enhancement, but a slow worsening of ambulation. Due to the patient’s age, a disease modifying therapy for multiple sclerosis was not established, the only drugs being represented by symptomatic agents.http://dx.doi.org/10.7175/cmi.v8i1.897

    Concurrent engineering is becoming a very important practice in manufacturing. A problem in concurrent engineering is the uncertainty associated with the values of the input variables and operating conditions. The problem discussed in this paper concerns the simulation of processes where the raw materials and the operational parameters possess fuzzy characteristics. The processing of fuzzy input information is performed by the vertex method and the commercial simulation packages POLYMATH and GEMS. The examples are presented to illustrate the usefulness of the method in the simulation of chemical engineering processes.

    2013-01-01

    Full Text Available Introduction: Multiple supernumerary teeth are a rare phenomenon. It occurs more often in patients with syndromes such as Gardner's syndrome, cleidocranial dysplasia and so on. This phenomenon in absence of such syndromes is rare. The purpose of this report was to introduce a case of non-syndromic multiple supernumerary impacted teeth.Case Report: A 29-year-old woman with no skeletal, metabolic, systemic and mental disorder was referred to oral and maxillofacial department of Mashhad dental school. In clinical evaluation, seven Permanent teeth were missing. In radiographic evaluation, there were a total of 15 impacted teeth which 7 of them were supernumerary.Conclusion: Missing or Excess of one or more teeth usually leads to occlusal and functional problems. In these cases, a complete clinical and radiographic examination accompanieal by a precise history should be performed to plan a suitable surgical-orthodontic-prosthetic treatment.

    2015-11-01

    This case report describes the multidisciplinary management of a young male who presented with a Class I incisor relationship and bi-maxillary dento-alveolar protrusion on a Class I skeletal base. The occlusion was complicated by an ankylosed and moderately infra-positioned upper left permanent central incisor, an anterior crossbite, crowding, a reduced overbite and centreline discrepancy. The incisor was traumatised and avulsed when the root was immature and the tooth was reimplanted with delay. On referral for orthodontic treatment at age 11 .5 years, the upper left central incisor was experiencing ankylosis-related (osseous replacement) resorption and external root resorption simultaneously. Aside from the orthodontic aims, it was important to address the disrupted alveolar development to facilitate later prosthodontic replacement of the upper left permanent central incisor by idealising the inter-coronal and inter-radicular spaces. Treatment consisted of fixed orthodontic appliances in conjunction with the extraction of all second premolars and the upper left permanent central incisor with episodic surgical curettage. An upper Hawlix retainer was provided immediately at debond and a cantilevered resin-retained bridge was placed four months later.

    2012-01-01

    Full Text Available The serotonin syndrome, which is characterized by psychiatric, autonomic nervous and neurological symptoms, is considered to be caused by excessive stimulation of the 5-HT1A and 5-HT2 receptors in the gray matter and spinal cord of the central nervous system, after the start of dosing or increase of the dose of a serotoninergic drug. There have been hardly any reports of induction of serotonin syndrome by electroconvulsive therapy (ECT in combination with antidepressant. We present the case of a female patient with major depressive disorder (MDD who developed transient serotonin syndrome soon after the first session of ECT in combination with paroxetine. Paroxetine was discontinued, and her psychiatric, autonomic nervous and neurological symptoms were gradually relieved and disappeared within 2 days. We performed the second ECT session 5 days after the initial session and performed 12 sessions of ECT without any changes in the procedure of ECT and anesthesia, but no symptoms of SS were observed. Finally, her MDD remitted. ECT might cause transiently increased blood-brain barrier (BBB permeability and enhance the transmissivity of the antidepressant in BBB. Therefore, it is necessary to pay attention to rare side effect of serotonin syndrome by ECT in combination with antidepressant.

    Leiomyomas are the most common benign tumors of the esophagus. They usually occur as a single lesion or as two or three nodules. Only two cases of esophageal multiple leiomyomas comprising more than 10 nodules have been reported previously. Moreover, there have been few reports of esophageal squamous cell carcinoma overlying submucosal tumors. We describe a 71-yearold man who was diagnosed as having a superficial esophageal cancer coexisting with two or three leiomyoma nodules. During surgery, 10 or more nodules that had not been evident preoperatively were palpable in the submucosal and muscular layers throughout the esophagus. As intramural metastasis of the esophageal cancer was suspected, we considered additional lymphadenectomy, but had to rule out this option because of the patient's severe anoxemia. Microscopic examination revealed that all the nodules were leiomyomas (20 lesions, up to 3 cm in diameter), and that invasion of the carcinoma cells was limited to the submucosal layer overlying a relatively large leiomyoma.This is the first report of superficial esophageal cancer coexisting with numerous solitary leiomyomas. Multiple minute leiomyomas are often misdiagnosed as intramural metastasis, and a leiomyoma at the base of a carcinoma lesion can also be misdiagnosed as tumor invasion.The present case shows that accurate diagnosis is required for the management of patients with coexisting superficial esophageal cancer and multiple leiomyomas.

    Full Text Available Alemtuzumab, a humanized monoclonal antibody targeting the surface molecule CD52, leads to a rapid depletion of immune cells in the innate and adaptive immune system. In phase 2 and 3 trials in multiple sclerosis (MS, infections have been reported more frequently in alemtuzumab than in interferon beta treated patients. Here we report two patients treated with alemtuzumab for MS developing Listeria meningitis few days after the first infusion cycle. Both patients recovered completely after prompt diagnosis and adequate treatment. Physicians and patients should be aware of this serious, but treatable complication.

    Full Text Available Background: There are few reports of glomerulonephritis (GN with crescents and a rapidly progressive course that lead to a diagnosis of a previously unsuspected B-cell dyscrasia. Case Presentation: We report a case of rapidly progressive GN: the patient showed no evidence of etiology at the time of biopsy and was diagnosed as IgA multiple myeloma (MM during investigation based on a renal biopsy. He presented diffuse proliferative and exudative GN and marked plasma cell infiltration of the kidney.

    Full Text Available Stroke is an uncommon disorder in children but an increasingly recognized cause of disability. Acute stroke may be attributable to trauma, but this topic is seldom discussed. In limited reports, most ischemic strokes following trauma were detected after a considerable delay. Early recognition of stroke following trauma might reduce secondary neurologic complications. We report a case of posterior cerebral artery area infarct following multiple traumas in a child. A comprehensive etiologic survey was undertaken and discussed. Although the definite pathogenesis is still unclear, adequate, individualized, and uncomplicated management can significantly affect the outcome.

    Cortical speech disorders rarely occur in multiple sclerosis (MS). We report a patient with relapsing-remitting MS, who presented with acute verbal dyspraxia. Magnetic resonance imaging (MRI) demonstrated an acute T2/Flair hyperintense, primarily white matter lesion underlying the middle third of the inferior frontal gyrus. The verbal dyspraxia cleared beginning 48 hours after the initiation of iv dexamethasone. Follow-up MRI demonstrated qualitative and quantitative diminution of the hyperintensity. This is the first report of a clinically definite MS patient with acute verbal dyspraxia. Moreover, there was a suggestive localization of verbal praxis to Brodmann areas 44/45.

    Tarlov or perineural cysts are cerebrospinal fluid (CSF)-filled sacs found between the perineurium and epineurium of the nerve roots. It is still unsure whether the origin of these cysts is intradural or extradural. They can either be asymptomatic or create a variety of negative impacts on comfort and quality of life. In this case report, we describe the presentation of multiple Tarlov cysts including one large cyst discovered during a routine cadaveric spinal dissection and the relevant and related literature. To our knowledge, this is the only cadaveric case report of Tarlov cysts and offers an interesting window into their anatomy.

    Sobieszczanski-Sobieski, Jaroslaw; Watson, Brian; Vanderplaats, Garrett

    2004-01-01

    The purpose of this research is to investigate the potential application of new methods for solving large-scale static structural problems on concurrent computers. It is well known that traditional single-processor computational speed will be limited by inherent physical limits. The only path to achieve higher computational speeds lies through concurrent processing. Traditional factorization solution methods for sparse matrices are ill suited for concurrent processing because the null entries get filled, leading to high communication and memory requirements. The research reported herein investigates alternatives to factorization that promise a greater potential to achieve high concurrent computing efficiency. Two methods, and their variants, based on direct energy minimization are studied: a) minimization of the strain energy using the displacement method formulation; b) constrained minimization of the complementary strain energy using the force method formulation. Initial results indicated that in the context of the direct energy minimization the displacement formulation experienced convergence and accuracy difficulties while the force formulation showed promising potential.

Both antiplatelet and anticoagulation therapy should be adopted for patients with arteriovenous embolism. Balancingthe risk ofischemia and hemorrhage is especially challenging in these patients in order to achieve an optimal clinical benefit. We report on a 55-year-old female with acute pulmonary embolism (PE), subsequently diagnosed as having acute myocardial infarction (AMI) and a cerebral infarction. Examinations had been carried out, excluding potential arteriovenous shunts, cancer, an-tiphospholipid syndrome and other common hypercoagulable states. A combination of an anticoagulant drug (riva-roxaban, an Xa inhibitor) and an antiplatelet agent (clopidogrel, an ADP receptor inhibitor) was prescribed with aβ-blocker and atorvastatin. The embolus was gradually shrunk during the next 10 months, and then it turned back into expanding. During the 16 months’ folow-up, an aneurysm of left ventricular apex was found through an

    A notation is presented for concurrent programs called program composition notation (PCN). The notation is being implemented at Caltech on multicomputers (a network of computers that communicate by sending and receiving messages). A fragment of this notation has been implemented on a data-parallel computer, the Connection Machine. The central ideas underlying PCN are discussed.

    2013-07-01

    Full Text Available Background: Patients with hematologic malignancies are at risk of advanced tuberculosis. The prevalence of tuberculosis between these patients is 2.1- 2.6 percent. The cellular immune deficiency caused by hematologic malignancies and or its treatment increases the risk of tuberculosis in these patients. Multiple Myeloma is malignant proliferations of plasma cells that involves different classes of immune system. Cellular and humeral immune deficiency due to the Multiple Myeloma and drugs for its treatment results in susceptibility to unusual infections. Infections are of the important factors of morbidity and mortality in patients suffering from multiple myeloma ,but coincidence of Multiple Myeloma and tuberculosis  is rare and very little has been reportedCase presentation: In this paper a 60-year-old woman from Kermanshah, Iran who is suffering from back pain, weight loss, weakness and sweating will be introduced. Spondylitis was seen in her lumbar imaging. Her husband suffered from pulmonary tuberculosis. In diagnostic studies tuberculose spondylitis and multiple myeloma were diagnosed simultaneously.Conclusion: Although the accompanying of Multiple Myeloma and tuberculosis is not common, but immunodeficiency caused by a hematologic malignancy as well as a history of close contact with a patient with tuberculosis resulted in tuberculosis of spine in this patient. Clinical features of abovementioned diseases are very similar. But in endemic area for tuberculosis, this disease should be considered because delay in diagnosis leads to increment in mortality and morbidities. Diagnosis of tuberculos spondylitis is based on radiologic and histologic features of the disease and on the response to treatment because the sensitivity of definitive diagnostic tests such as culture and PCR is low in extra pulmonary tuberculosis.

  2. Concurrent bilateral ectopic pregnancy: a rarity

    Full Text Available Bilateral ectopic pregnancy is a rare twin gestation with only a few cases reported in the literature. We report a 30 year old woman without any high risk factor for ectopic pregnancy, who had concurrent bilateral ectopic pregnancy. A 30 year old female presented to the Gynecology emergency department complaining of vaginal bleeding and abdominal pain. The presumptive diagnosis of ruptured left sided ectopic pregnancy was made on basis of clinical findings and ultrasound finings. An emergency laparotomy was done revealed a hemoperitoneum of 1.5 liters, a ruptured left tubal pregnancy with active bleeding and right tubal un-ruptured ectopic was found. A bilateral salpingectomy was performed. Histopathology confirmed presence of chorionic villi in both tubes. In theory, laparoscopic salpingostomy is the best surgical approach in bilateral tubal pregnancy. However, bilateral salpingectomy may be necessary when both tubes are extensively damaged or are actively bleeding. Successful pregnancies have been reported after conservative surgical treatment of bilateral ectopic, but the risk of recurrence is high. Our decision for an emergency laparotomy followed by bilateral salpingectomy was based on the fact that the patient presented with acute abdomen and was haemodynamically unstable and there was extensive bilateral tubal damage. As the incidence of ectopic pregnancies is increasing concurrently with the incidences of pelvic inflammatory disease and use of assisted fertility techniques; it may be that these and ldquo;rare ectopics and rdquo; will become less uncommon.

  3. Artificial concurrent catalytic processes involving enzymes.

    Science.gov (United States)

    Köhler, Valentin; Turner, Nicholas J

    2015-01-11

    The concurrent operation of multiple catalysts can lead to enhanced reaction features including (i) simultaneous linear multi-step transformations in a single reaction flask (ii) the control of intermediate equilibria (iii) stereoconvergent transformations (iv) rapid processing of labile reaction products. Enzymes occupy a prominent position for the development of such processes, due to their high potential compatibility with other biocatalysts. Genes for different enzymes can be co-expressed to reconstruct natural or construct artificial pathways and applied in the form of engineered whole cell biocatalysts to carry out complex transformations or, alternatively, the enzymes can be combined in vitro after isolation. Moreover, enzyme variants provide a wider substrate scope for a given reaction and often display altered selectivities and specificities. Man-made transition metal catalysts and engineered or artificial metalloenzymes also widen the range of reactivities and catalysed reactions that are potentially employable. Cascades for simultaneous cofactor or co-substrate regeneration or co-product removal are now firmly established. Many applications of more ambitious concurrent cascade catalysis are only just beginning to appear in the literature. The current review presents some of the most recent examples, with an emphasis on the combination of transition metal with enzymatic catalysis and aims to encourage researchers to contribute to this emerging field.

    Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic small- and medium-sized-vessel vasculitis. The literature contains only a few reports of gastrointestinal perforation with this condition. We report a patient with EPGA treated with high-dose steroid who underwent emergency surgery for intestinal perforations. We performed a simple repair of the 11 perforations. Intestinal fistulas developed 8 d postoperatively; they healed well after 60 d of continuous washing and negative pressure suction. The clinical data of 14 additional patients with EGPA or Churg-Strauss syndrome complicated with gastrointestinal perforation, which were reported from 1996 to 2014, were also collected and compared. The formation of multiple perforations and fistulas following high dosage steroid administration can have a good outcome with appropriate management. Meticulous attention to abdominal symptoms and appropriate interventions can result in timely management. Corticosteroid administration remains a very important perioperative procedure for EPGA.

    2015-01-01

    Intussusceptions are generally associated with mechanical lead points or localized inflammation that function as foci for intestinal telescoping. We present the case of a patient whose abuse of anabolic steroids resulted in the development of multiple simultaneous intussusceptions. Our patient had no additional identifiable risk factors for intussusception. Consistent with previous reports, corticosteroid induced polycythemia and its consequent hyperviscosity led to intravascular sludging and mesenteric ischemia with associated bowel wall thickening. The localized intestinal induration then served as mechanical foci for intussusception. Due to the illicit nature of anabolic androgenic steroid (AAS) abuse, the physiologic effects of supraphysiologic doses are sparsely reported and poorly understood. The scope of AAS abuse and its consequences are likely under-reported and under-recognized within the medical community. Our case presented a unique diagnostic and therapeutic challenge with which we aim to increasing awareness and clinical suspicion for AAS among healthcare personnel.

    Full Text Available Abstract Introduction Simultaneous involvements of multiple cranial nerve ganglia (geniculate ganglion and peripheral ganglia of cranial nerves VIII, IX and X by varicella-zoster virus and its subsequent activation may result in the characteristic eruptions of herpes zoster cephalicus. Coexistence of facial palsy and involvement of upper cervical dermatomes by varicella-zoster virus is quite rare. Case presentation Here, we report a 71-year-old Iranian man with involvement of multiple sensory ganglia (geniculate ganglion and upper dorsal root ganglia by varicella-zoster virus. He presented with right-sided facial weakness along with vesicular eruptions on the right side of his neck, and second and third cervical dermatomes. Conclusion The present case is an example of herpes zoster cephalicus with cervical nerve involvement. Although resembling Ramsay Hunt syndrome with presence of facial nerve paralysis and accompanying vesicles, involvement of cervical dermatomes is not a feature of the classic Ramsay Hunt syndrome.

    2017-03-01

    Full Text Available Hyperdontia or supernumerary teeth in both arches without any syndromic manifestation are extremely rare. Supernumerary teeth are commonly associated with Gardner’s syndrome, cleft lip and palate, cleidocranial dysplasia and trichorhinopha-langeal syndrome. Five cases of non-syndromic multiple premolars of maxillary and mandibular arches in Indian patients are presented here. This case series reports three cases with multiple (9 in maximum, bilaterally impacted and erupted supernumerary teeth and two cases with supernumerary premolars in non-syndromic cases from Indian patients. Supernumerary teeth can be present in any region of the oral cavity. Although the occurrence of maxillary para-premolars is rare, radio-logical investigations play a major and decisive role in determining the management of such cases.

    Pyogenic granuloma (PG) is a benign vascular lesion of the skin and mucous membranes, presenting as a solitary, red, pedunculated papule that bleeds easily and which appears to be a reactive vascular proliferation to minor injury. These lesions are more common in children and are mostly seen in exposed sites. Multiple disseminated PG is a rare condition. This report describes an infant with multiple, disseminated, pyogenic granulomas following burns from boiling milk. We reviewed literature published in English and found 9 cases. Six cases were provoked by hot milk, 2 by hot water, while the cause of the other case is unknown. Angiogiogenetic activity in milk may explain PG development in these patients. PMID:27192522

    2014-01-01

    Full Text Available This report presents a case of severe intrusive luxation of multiple anterior teeth in an 11-year-old girl. The teeth were repositioned successfully by endodontic and orthodontic management. The case was monitored for 7 years. Depending on the severity of the injury, different clinical approaches for treatment of intrusive luxation may be used. Despite the variety of treatment modalities, rehabilitation of intruded teeth is always a challenge and a multidisciplinary approach is important to achieve a successful result. In this case, intruded teeth were endodontically treated with multiple calcium hydroxide dressings and repositioned orthodontically. The follow-up of such cases is very important as the repair process after intrusion is complex. After 7 years, no clinical or radiographic pathology was detected.

    2012-07-01

    Full Text Available Abstract Introduction Glossopharyngeal neuralgia is an uncommon, painful syndrome, characterized by paroxysms of pain in the sensory distribution of the 9th cranial nerve. Idiopathic glossopharyngeal neuralgia may be due to compression of the glossopharyngeal nerve by adjacent vessels, while secondary glossopharyngeal neuralgia is associated with identifiable lesions affecting the glossopharyngeal nerve at different levels of its neuroanatomic pathway. Glossopharyngeal neuralgia is rare in the general population, but is more common in patients with multiple sclerosis. Case presentation A 56-year-old Caucasian woman with multiple sclerosis and migraine presented to our facility with intermittent lancinating pain to the right of her throat, tongue, and the floor of her mouth that had been occurring for the past year. The pain was intense, sharp, and stabbing, which lasted two to six seconds with radiation to the right ear. Initially, the attacks were infrequent, however, they had become more intense and frequent over time. Our patient reported weight loss, headache, painful swallowing, and the inability to maintain sleep due to painful attacks. A neurological examination revealed a right-handed woman with trigger points in the back of the tongue and throat on the right side. She also had dysphagia, hoarseness, and pain in the distribution of the right glossopharyngeal nerve. Mild right hemiparesis, hyperreflexia, dysmetria, and an ataxic gait were present. A magnetic resonance imaging scan of the brain was consistent with multiple sclerosis and magnetic resonance angiography demonstrated a loop of the posterior inferior cerebellar artery compressing the right glossopharyngeal nerve. She responded satisfactorily to carbamazepine. Microvascular decompression and Gamma Knife® radiosurgery were discussed in case of failure of the medical treatment; however, she declined these options. Conclusions Glossopharyngeal neuralgia in multiple sclerosis may

    2007-06-01

    Full Text Available Abstract Multiple myeloma (MM is a relatively rare haematological malignancy seen in older persons. It has an unknown aetiology and usually occurs incidentally within a family. However, several families have been reported with multiple cases of MM, so that the existence of hereditary MM has been postulated although no causative germline mutations have been detected so far. First-degree relatives of MM patients have been reported to have a relative risk between two and four times higher than normal of developing MM and we presume the risks are higher for relatives in the case of familial MM. Here we report on two families with MM who requested presymptomatic screening of healthy relatives. Although risk estimates for asymptomatic relatives in these types of families are not available, a clinically significant risk of developing MM cannot be excluded. We suggest that, in a research setting, screening for MM could be offered to individuals with more than one first-degree affected relative, or to those with one first-degree and at least one second-degree relative with MM. We propose a screening programme of annual protein electrophoresis of blood and urine, starting at age 40 (or earlier if a family member presented with MM at a younger age.

    Various hepato-biliary complications are an increased incidence in patients with inflammatory bowel disease,and portal bacteremia is well documented in patients with ulcerative colitis (UC). However, few reports mention UC in association with liver abscesses. Recently, there are several reports describing cytomegalovirus (CMV) infection in association with disease exacerbation and steroid refractoriness in patients with UC. Here we present a case of refractory UC accompanied with multiple liver abscesses and CMV colitis. The patient, a 72-year-old male, with a five-year history of repeated admissions to our hospital for UC, presented with an exacerbation of his UC.Sigmoidoscopy performed on admission suggested that his UC was exacerbated, then he was given prednisolone and mesalazine orally, and betamethasone enemas.However, he had exacerbated symptoms. Repeat sigmoidoscopy revealed multiple longitudinal ulcers and pseudopolyps in the rectosigmoid colon. Although immunohistochemical staining of biopsy specimens and the serum testing for antigenemia were negative on admission and after the repeat sigmoidoscopy, they became histologically positive for CMV. Nonetheless, the patient developed spiking fevers, soon after ganciclovir was administered. Laboratory studies revealed an increased white cell count with left shift, and Enterococcus fecalis grew in blood cultures. An abdominal computed tomography (CT) scan was obtained and the diagnosis of liver abscesses associated with UC was made, based on CT results. The hepatic abscesses were successfully treated with intravenous meropenem for 6 wk, without further percutaneous drainage. To our knowledge, this is the first reported case of multiple liver abscesses that develop during UC exacerbation complicated by CMV colitis.

    Full Text Available Background: Some patients report hypersensitivity reactions to many drugs making it difficult to prescribe medications when they fall ill. Aim: To describe the clinical profile of multiple drug hypersensitivity and the results of challenge testing in a large teaching hospital.Methods: We performed a five-year retrospective review of the records of patients who complained of reactions to two or more unrelated drugs and avoided medication because of a fear of developing reactions. Oral challenge testing was carried out in hospital with drugs suspected by the patient to cause reactions and/or commonly prescribed medications. A positive reaction was diagnosed when symptoms and signs resembled previously experienced episodes and there was no such reaction with placebo. Results: Twenty three patients (aged 14-65 years; 19 females underwent challenge testing. Their complaints had been present for 1-30 years, with 2-40 drug reaction episodes reported. Antibiotics and non-steroidal anti-inflammatory drugs (NSAIDs were most commonly implicated, and urticaria/angioedema were the most often reported manifestations. The patients underwent 3-27 challenges with 1-24 drugs. Three had positive challenge reactions with various NSAIDs, 13 developed symptoms and signs that were judged not to be true reactions, and 7 had no reactions. None of our patients qualified for a diagnosis of true multiple drug hypersensitivity. Conclusion: Patients who believe they are allergic to multiple, pharmacologically unrelated drugs are usually mistaken. Challenge testing is a reliable way of demonstrating this and providing patients with a list of safe drugs.

    Treacher Collins syndrome is an autosomal dominant disorder of craniofacial development with an incidence of I in 40,000 to in 70,000 live births. It is characterized by abnormalities of the pinnae which are frequently associated with atresia of the external auditory canals and anomalies of the middle ear ossicles. Rarely congenital heart defects can be present. Prenatal paroxetine exposure may enhance the risks of major malformation, particularly cardiac defects. This article reports a newborn, whose mother used paroxetine during pregnancy, presenting with multiple congenital heart defects associated to typical physical characteristics of Treacher Collins syndrome.

    Brain vascular malformations are dynamic disorders. Although mostly considered to be of congenital origin, the improvement of clinical imaging and vasculogenesis knowledge has shown that they might also result from a biological dysfunction of the remodeling process after birth. Venous occlusive disease and ishemia may represent powerful revealing triggers and support the capillary venous origin of some vascular malformations. We report a unique case of the development of multiple de novo vascular malformations (transverse sinus dural fistula and posterior fossa cavernomas) following acoustic neuroma surgery. (orig.)

    Abdominal venous thrombosis may present either as Budd-Chiari syndrome (BCS) caused by hepatic vein or proximal inferior vena cava (IVC) obstruction or as an extra hepatic portal obstruction (EHPVO) caused by Portal vein thrombosis or mesenteric vein thrombosis, but a mixed involvement is uncommon. Multiple abdominal venous obstructions presenting with thrombosis of hepatic vein, IVC, portal vein and renal vein are very rarely seen . We are reporting a rare case with thrombosis of IVC, hepatic vein, portal vein and renal vein, with protein S and protein C deficiencies, which was managed by giving anticoagulant therapy.

    Full Text Available Epithelioid sarcoma is a rare soft tissue sarcoma and usually resistant to chemotherapy. It has high rates of local recurrence and distant metastasis, and the prognosis after metastasis is poor. We report a case of multiple lung metastases of an epithelioid sarcoma originating in the inguinal area that we treated with the multikinase inhibitor pazopanib. The patient was a 38-year-old male who began to experience discomfort in his left inguinal area. Magnetic resonance imaging showed a tumor extended from the medial aspect of the wing of the left ilium along the iliopsoas muscle to its site of insertion on the femur. The histopathological diagnosis with a biopsy was proximal-type epithelioid sarcoma. Although a positron emission tomography examination showed fluorodeoxyglucose accumulation in the left inguinal tumor, there was no distant metastasis. Wide resection by a combined iliac resection procedure was performed. Twelve months after surgery, computed tomography revealed multiple nodules and a diagnosis of bilateral multiple lung metastases was made. Treatment with pazopanib 800 mg was started. After 2.5 months of treatment, a clear reduction in the size of the pulmonary metastases was shown. Thirty months after the start of pazopanib treatment, most of the metastases have disappeared, and no development of new lesions has been seen. Therefore, it appeared that pazopanib was capable of serving as one of the choices of therapeutic agents that should be taken into consideration for the treatment of advanced epithelioid sarcoma.

    Although infectious diseases are the most prevalent cause of fevers of unknown origin (FUO), this diagnosis remains challenging in some pediatric patients. Imaging exams, such as computed tomography (CT) are frequently required during the diagnostic processes. The presence of multiple hypoattenuating scattered images throughout the liver associated with the history of cohabitation with cats should raise the suspicion of the diagnosis of cat-scratch disease (CSD), although the main etiologic agent of liver abscesses in childhood is Staphylococcus aureus. Differential diagnosis by clinical and epidemiological data with Bartonella henselae is often advisable. The authors report the case of a boy aged 2 years and 9 months with 16-day history of daily fever accompanied by intermittent abdominal pain. Physical examination was unremarkable. Abdominal ultrasound performed in the initial work up was unrevealing, but an abdominal CT that was performed afterwards disclosed multiple hypoattenuating hepatic images compatible with the diagnosis of micro abscesses. Initial antibiotic regimen included cefotaxime, metronidazole, and oxacillin. Due to the epidemiology of close contact with kittens, diagnosis of CSD was considered and confirmed by serologic tests. Therefore, the initial antibiotics were replaced by clarithromycin orally for 14 days followed by fever defervescence and clinical improvement. The authors call attention to this uncommon diagnosis in a child presenting with FUO and multiple hepatic images suggestive of micro abscesses.

    Preservation of the primary dentition until the normal time of exfoliation is one of the most important factor involved in preventive and interceptive dentistry. The premature loss of second primary molar before the eruption of permanent first molar can create a significant arch space/tooth size discrepancy. Distal shoe space maintainer is a valuable part of the Paediatric Dentist's armamentarium in those cases where the second primary molar is prematurely lost and it helps to guide the first permanent molar into place. Conventional design poses various limitations in cases of premature loss of multiple deciduous molars. Thus, it is required to modify the conventional designs according to the needs of the patient. This case report describes an innovative modification of distal shoe appliance in cases of premature loss of multiple deciduous molars. In the present case, modification of distal shoe space maintainer was advocated because of inadequate abutments caused due to multiple loss of deciduous molars. Bilateral design of distal shoe was planned for unilateral loss of deciduous molars.

The presence of multiple hypoattenuating scattered images throughout the liver associated with the history of cohabitation with cats should raise the suspicion of the diagnosis of cat-scratch disease (CSD, although the main etiologic agent of liver abscesses in childhood is Staphylococcus aureus. Differential diagnosis by clinical and epidemiological data with Bartonella henselae is often advisable. The authors report the case of a boy aged 2 years and 9 months with 16-day history of daily fever accompanied by intermittent abdominal pain. Physical examination was unremarkable. Abdominal ultrasound performed in the initial work up was unrevealing, but an abdominal CT that was performed afterwards disclosed multiple hypoattenuating hepatic images compatible with the diagnosis of micro abscesses. Initial antibiotic regimen included cefotaxime, metronidazole, and oxacillin. Due to the epidemiology of close contact with kittens, diagnosis of CSD was considered and confirmed by serologic tests. Therefore, the initial antibiotics were replaced by clarithromycin orally for 14 days followed by fever defervescence and clinical improvement. The authors call attention to this uncommon diagnosis in a child presenting with FUO and multiple hepatic images suggestive of micro abscesses.

    Transplantation centers have historically considered a history of multiple myeloma as a contraindication to kidney transplantation due to high recurrence rates and poor transplant survival. However, there have been significant advances in the treatment of multiple myeloma, with improved patient survival, which may allow for successful kidney transplantation in these patients. We report on 4 patients who underwent kidney transplantation at our institution between 2009 and 2015 after having achieved a very good partial response or better with chemotherapy and autologous stem cell transplantation. All 4 patients received kidneys from living donors; 2 underwent induction therapy with basiliximab, and 2, with thymoglobulin. One patient had progression of myeloma, which responded well to therapy. All had functioning transplants at 1 year after kidney transplantation. No patients experienced a rejection episode or infections with BK polyomavirus or cytomegalovirus, with follow-up ranging from 16 to 58 months after kidney transplantation. Our experience suggests that kidney transplantation is feasible in a subset of patients with multiple myeloma. Future studies are necessary to compare outcomes in these patients with other high-risk patients undergoing kidney transplantation. Copyright © 2017 National Kidney Foundation, Inc.

    A rare case is reported in which multiple cerebral aneurysm occurred after radiotherapy. A female aged 51 was hospitalized with a chief complaint of consciousness disorder. The patient was discharged from the hospital 1 year before, after undergoing subtotal extirpation of a tumor through the transsphenoidal sinus in a case of pituitary adenoma, and post-operative radiotherapy (topical 50 Gy). Mild hyperlipidemia associated with hypothyroidism was observed by blood biochemical test during hospitalization. Multiple cerebral infarction was observed by CT scanning and MR imaging. Conservative treatment including intensified endocrine-supplementing treatment was performed. Thyroid gland function and hyperlipidemia improved, but the consciousness disorder occurred suddenly 6 weeks after hospitalization. Subarachnoid hemorrhage and hydrocephalus were observed by CT scanning. Cerebral angiography detected a saccular aneurysm in the trifuraction of the right middle cerebral artery, 3 fusiform aneurysms in the periphery of the right middle cerebral artery, 2 fusiform aneurysms in the posterior cerebral artery. These findings were not observed at the initial hospitalization but were unexceptionally confined to all the irradiation fields. The patient died 8 weeks after hospitalization, and no autoptic findings was obtained. We presumed that radiation vasculopathy, caused by radiation therapy done one year previously, had led to the occurrence of multiple cerebral aneurysms. We think that hyperlipidemia may have acted as an exacerbating factor responsible for these aneurysms. (author).

    Multiple tumor-like ectopic calcifications is a rare syndrome characterized by subcutaneous mass deposits of calcium phosphate in periarticular tissues. Although several cases of the surgical treatment of tumoral calcinosis have been reported, the present case is unique in that multiple ectopic calcifications in subcutaneous tissues were found in a hemodialysis patient who had been operated on a total of five times within a period of 1.5 years. A hemodialysis 60-year-old male presented with multiple tumor-like ectopic calcifications bilateral in the shoulders, right buttock and right thigh. He had been operated on a total of five times within a period of 1.5 years; the operations included a subtotal parathyroidectomy with parathyroid autotransplantation in the right forearm. Complete excisions of the ectopic calcifications were performed in the left shoulder, right buttock and right thigh, without signs of recurrence in the same sites at follow-up. Incomplete excision of the ectopic calcification in the right shoulder resulted in recurrence in the same site, and the patient was operated on two more times 1.5 years following the initial surgery. Subtotal parathyroidectomy with parathyroid autotransplantation decreased serum levels of PTH, but the levels of serum calcium and phosphorus remained unchanged post-surgery, which appeared not to inhibit the recurrence of ectopic calcification in patients with CRF. If conservative therapy failed, then early and complete surgical excision may be a good therapeutic option. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

    It is estimated that early-onset multiple sclerosis multiple sclerosis (early-onset multiple sclerosis) approximately incorporates 3-5% of the multiple sclerosis population. In this report on early-onset multiple sclerosis, the authors aimed to define demographic, clinical and imaging features in a case-series of true-childhood multiple sclerosis and to compare its characteristics with juvenile multiple sclerosis. The authors inspected the records of multiple sclerosis patients who were registered by Isfahan MS Society. Clinical and demographic data of children with less than 16 years of age were reviewed retrospectively. Out of 4536 multiple sclerosis patients referred to the authors' center, 221 patients (4.8%) had multiple sclerosis starting at the age of 16 or less (11 true-childhood multiple sclerosis vs 210 juvenile-onset multiple sclerosis); the female to male ratio was 4.81:1. In the mean follow-up period of 6.2 years, 22 patients (10.5%) had positive family history of multiple sclerosis, 196 (88.6%) patients were classified as relapsing-remitting multiple sclerosis, the mean (± SD Expanded Disability Status Scale) was 1.5 ± 1.1 at the last evaluation. The most common initial presentation was optic nerve involvement (36.1%) and cerebellar sign and symptoms (14.6%). In all, 13 patients (5.8%) had experienced seizure in the course of multiple sclerosis. This study indicated that early-onset multiple sclerosis is not rare condition and overwhelmingly affects girls even at prepubertal onset. Physicians should consider multiple sclerosis in suspicious pediatric cases.

    Full Text Available BACKGROUND: It is not known whether the addition of chemotherapy to radiation therapy improves outcomes in primary vaginal cancer. Here, we review clinical outcomes in patients with primary vaginal cancer treated with radiation therapy (RT or concurrent chemoradiation therapy (CRT. METHODS: Seventy-one patients with primary vaginal cancer treated with definitive RT with or without concurrent chemotherapy at a single institution were identified and their records reviewed. A total of 51 patients were treated with RT alone; 20 patients were treated with CRT. Recurrences were analyzed. Overall survival (OS and disease-free survival (DFS rates were estimated using the Kaplan-Meier method. Cox regression analysis was performed. RESULTS: The median age at diagnosis was 61 years (range, 18-92 years and the median follow-up time among survivors was 3.0 years. Kaplan-Meier estimates for OS and DFS differed significantly between the RT and CRT groups (3-yr OS = 56% vs. 79%, log-rank p = 0.037; 3-yr DFS = 43% vs. 73%, log-rank p = 0.011. Twenty-three patients (45% in the RT group had a relapse at any site compared to 3 (15% in the CRT group (p = 0.027. With regard to the sites of first relapse, 10 patients (14% had local only, 4 (6% had local and regional, 9 (13% had regional only, 1 (1% had regional and distant, and 2 (3% had distant only relapse. On univariate analysis, the use of concurrent chemotherapy, FIGO stage, tumor size, and date of diagnosis were significant predictors of DFS. On multivariate analysis, the use of concurrent chemotherapy remained a significant predictor of DFS (hazard ratio 0.31 (95% CI, 0.10-0.97; p = 0.04. CONCLUSIONS: Vaginal cancer results in poor outcomes. Adequate radiation dose is essential to ensure curative management. Concurrent chemotherapy should be considered for vaginal cancer patients.

    Full Text Available Introduction: Multiple endocrine neoplasia type IIa (MEN IIa is an autosomal dominant syn-drome characterized bypheochromocytoma ,medullary thyroid carcinoma and hyperparathy-roidism. Pheochromocytoma approximately occurs in 50% of patients with MEN IIa. This tumor has the capacity to produce ACTH ectopically and becomes manifest like Cushing syndrome,although it is very rare. Case Report: We report a 26-year-old woman patient with severe muscle weakness, skin le-sions in extremity, hypertension, new onset diabetes and in the laboratory data hypokalemia, metabolic alkalosis, high serum level of cortisol, metanephrine, normetanephrine, calcitonin and bilateral adrenal mass in computed tomography as the first clinical manifestations of an ACTH-secreting pheochromocytoma. Conclusion: In the patients with hypertension, new onset diabetes and hypokalemia Cushing syndrome and pheochromocytoma should always be ruled out. (Sci J Hamadan Univ Med Sci 2013; 20 (3:260-265

    Status epilepticus (SE) represents a medical emergency that annually affects 60,000--150,000 individuals in the United States. Selective neuronal loss in vulnerable areas has been pathologically demonstrated following convulsive SE primarily affecting the limbic system, thalamus and cerebellum. Morbidity in those cases that follow refractory SE (RSE) is poorly documented. There have been anecdotal reports of surgical treatment for this condition, especially secondary to brain lesions. We report a 6-year-old patient who was in RSE for 60 days, without a brain lesion documented by MRI. The patient underwent multiple subpial transection (MST) of the sensorimotor cortex, which by ictal EEG and ictal SPECT proved to be the epileptogenic zone. We conclude that MST should be considered as an alternative treatment for refractory partial SE.

    The Multiple Congenital Anomalies-Hypotonia-Seizures Syndrome 1 (MCAHS1) has been described in two families to date. We describe a 2-year-old Mexican American boy with the syndrome and additional manifestations not yet reported as part of the phenotype. The patient presented with severe hypotonia, microphallus and left cryptorchidism, and was later diagnosed with epilepsy and severe cortical visual impairment. He also had supernumerary nipples, pectus excavatum, a short upturned nose, fleshy ear lobes, and a right auricular pit. Massively parallel exome sequencing and analysis revealed two novel compound heterozygous missense (Trp136Gly and Ser859Thr) variants in the PIGN gene. This report extends and further defines the phenotype of this syndrome.

    @@ Introduction The association between pulmonary interstitial fibrosis and the development of bronchogenic carcinoma in a patient with scleroderma has been reported rarely[1]. It is hypothesized that intense epithelial proliferation that is accompanied by the .brotic process increases the occurrence of carcinomatous changes[2]. We report the case of a pa-tient who presented with 3-year history of Raynaud's phenomenon, gradual tightening of the skin which was ignored by the patient and her family members, and a 2-week history of severe respiratory dis-tress with left shoulder and upper back pain followed by the develop-ment of paraparesis. After a series of examinations, the patient was diagnosed with scleroderma and simultaneously with bronchogenic carcinoma and multiple distant metastases.

    Full Text Available Context Venous thrombosis has been described in patients with acute and chronic pancreatitis. This is especially common in portal vein, splenic vein and superior mesenteric vein. To the best of our knowledge, involvement of superior vena cava and subclavian vessel due to pancreatitis has not been reported. Case report We present here a case of an adult male with alcoholic chronic pancreatitis who presented with multiple vessel thromboses involving superior vena cava, inferior vena cava, bilateral subclavian, internal jugular vein, axillary, iliac and renal vein without involvement of portal, splenic and superior mesenteric vein that was effectively treated with i.v. anticoagulation therapy. Conclusion Venous thromboses can occur outside the splanchnic circulation in pancreatitis.

    2013-01-01

    Dubin-Johnson syndrome (DJS) is a rare autosomal recessive inheritance disorder of bilirubin metabolism. Herein we reported a complicated but interesting case which is readily resulted in misdiagnosis or an indefinite diagnosis, and this is the first reported familial case of DJS with multiple liver cavernous hemangiomas. A 49-year-old man was referred to our hospital for jaundice and multiple low-density liver masses. Extensive laboratory investigations showed conjugated hyperbilirubinaemia and positive urine bilirubin. Microscopically, lesions were composed of blood-filled vascular channels of various sizes lined by a single layer of flat endothelial cells supported by fibrous tissue. Coarse brown granules presented in the hepatocytes of the liver lobules locating beside the tumor, particularly in the centrilobular hepatocytes, and the granules showed blue-green with Schmorl's reaction lipofuscin staining. Interestingly, one of the patient's six siblings (female) shared the same condition with him. The relationship between DJS and hemangiomas remains unclear, and it might be contributed to some hereditary factors, or probably occurred simultaneously by chance. It was certified that the true reason for the long-term unclear jaundice was DJS, which was presumed clinically to be caused by bile excretion obstacles associated with the hemangiomas. Liver biopsy and histochemical stain may be helpful to identify the reason of jaundice and avoid misdiagnosis or an indefinite diagnosis.

  3. Concurrent hypokalemic periodic paralysis and bipolar disorder

    Directory of Open Access Journals (Sweden)

    Chia-Lin Lin

    2015-01-01

    Full Text Available Primary periodic paralysis is a rare autosomal dominant disorder of ion-channel dysfunction, manifested by episodic flaccid paresis secondary to abnormal sarcolemma excitability. Membrane destabilization involving Na, K-ATPase has been hypothesized to be a biological etiology of the bipolar disorder (BD and the mechanisms underlying lithium therapy have been linked to it. To date, there has been only one reported case of BD comorbid with periodic paralysis. Herein, we reported another case of concurrent bipolar mania and hypokalemic periodic paralysis (HPP, one special form of periodic paralysis. Consistent with the previous case, our patient responded well to lithium treatment for both bipolar mania and HPP. This might provide some support to the hypothesis that the therapeutic effects of lithium in both BD and HPP could be due to the correction of the underlying common pathophysiology.

    Watson, Angela; Watson, Barry; Vallmuur, Kirsten

    2015-10-01

    The reliance on police data for the counting of road crash injuries can be problematic, as it is well known that not all road crash injuries are reported to police which under-estimates the overall burden of road crash injuries. The aim of this study was to use multiple linked data sources to estimate the extent of under-reporting of road crash injuries to police in the Australian state of Queensland. Data from the Queensland Road Crash Database (QRCD), the Queensland Hospital Admitted Patients Data Collection (QHAPDC), Emergency Department Information System (EDIS), and the Queensland Injury Surveillance Unit (QISU) for the year 2009 were linked. The completeness of road crash cases reported to police was examined via discordance rates between the police data (QRCD) and the hospital data collections. In addition, the potential bias of this discordance (under-reporting) was assessed based on gender, age, road user group, and regional location. Results showed that the level of under-reporting varied depending on the data set with which the police data was compared. When all hospital data collections are examined together the estimated population of road crash injuries was approximately 28,000, with around two-thirds not linking to any record in the police data. The results also showed that the under-reporting was more likely for motorcyclists, cyclists, males, young people, and injuries occurring in Remote and Inner Regional areas. These results have important implications for road safety research and policy in terms of: prioritising funding and resources; targeting road safety interventions into areas of higher risk; and estimating the burden of road crash injuries.

    Predicting caregiving status (CS) in multiple sclerosis (MS) is of both clinical and health policy-making value. The aim of this cross-sectional study was to assess the clinical predictors of CS, along with factors related to caregivers' stress. A sample of 342 clinically definite MS patients (67.5% females, 67.8% relapsing MS, mean age 43.1 ± 11.4 year-old, mean disease duration 147 ± 105.4 months, median Expanded Disability Status Scale -EDSS-3.0) was screened for CS. The Multiple Sclerosis Quality of Life-54 and Zarit Burden Interview were used to measure quality of patients' life and the their caregivers' burden, respectively. In total, 57.9% of patients reported at least one caregiver, 97% of which were relatives or friends. Higher EDSS was associated with higher chance of reporting a caregiver. Two EDSS cut-offs were recognized; 2.0 and 4.5, the former with increased sensitivity (78.8%) and the latter with increased specificity (82.3%) to predict CS. Patients in the mild disability group (EDSS: 0-1.5) needing a caregiver had higher subjective cognitive function, implying presumably a beneficial role of care in cognition. Age and education were showed to affect CS in the moderate disability group (EDSS: 2.0-4.5). Physical and mental disability was more pronounced in patients reporting at least one caregiver in the high disability group (EDSS above 4.5). Caregivers' stress was significantly positively correlated with age, EDSS, and duration of the disease and negatively with cognitive, physical, and mental health. In conclusion, the clinical predictors of CS are known to serve well both the researchers and the clinicians.

  8. Concurrent fractional and equilibrium crystallisation

    Science.gov (United States)

    Sha, Lian-Kun

    2012-06-01

    This paper proposes the concept of concurrent fractional and equilibrium crystallisation (CFEC) in a multi-phase magmatic system in light of experimental results on diffusivities of elements and other species in minerals and melts. A group of equations are presented to describe how the concentrations of an element or isotope change in fractionated solid, equilibrated solid, melt, liquid, and gas phases, as well as in magma, as a function of distribution coefficients and mass fractions during the CFEC process. CFEC model is a generalised and unified formulation that is valid, not only for pure fractional crystallisation (FC) and perfect equilibrium crystallisation (EC) singly, as two of its limiting end-member cases, but also for the geologically more important process of concurrent fractional and equilibrium crystallisation. The concept that both fractional and equilibrium crystallisation can operate concurrently in a magmatic system, for a given element, among different minerals, and even within different-sized crystal grains of the very same mineral phase, is of fundamental importance in deepening our current understanding of magmatic differentiation processes. CFEC probably occurs more frequently in the natural world than either pure fractional or perfect equilibrium crystallisation alone, as a result of the interplay of varying diffusivities of elements under diverse physicochemical conditions, different residence time and growth rates of mineral phases in magmas, and varying grain sizes within each phase and among different phases. The marked systematic variations in trace element concentrations in the melts of the Bishop Tuff have long been perplexing and difficult to reconcile with existing models of differentiation. CFEC, which is able to better explain the scatter trends in a systematic way than fractional crystallisation, is considered to be the cause.

  9. Concurrent engineering teams. Volume 2: Annotated bibliography

    Richter, Karen J.; Dierolf, David A.

    1990-11-01

    Specific concurrent engineering practices vary among organizations. There are, however, various management practices that appear to work well for most organizations. This paper presents the reader with specific, useful examples from several defense contractors illustrating how multifunctional concurrent engineering teams are being organized and managed and how concurrent engineering team meetings are conducted and supported. The types of computer support that could be used to enhance the efficiency and effectiveness of concurrent engineering team meetings are identified. The general findings are that there exists a direct relationship between total quality management (TQM) and concurrent engineering, and that many applications of computer-aided group problem solving are possible and practical today for the concurrent engineering team meetings. Areas identified for additional research are the documentation of the decision process and rationale during the product and process definition, the capturing of lessons learned during the implementation of concurrent engineering, and the performance evaluation and training of team members.

    2010-02-01

    Sexual partner concurrency, which fuels the spread of HIV, has been hypothesized as a cause of higher rates of HIV among low-income, urban African-Americans. Despite this hypothesis, little is known about the phenomenology of partner concurrency. To address this gap in the literature, we recruited 20 urban African-American men from a public STD clinic to elicit their ideas about partner concurrency. Five themes emerged during focus group discussions. First, there was a general consensus that it is normative to have more than one sexual partner. Second, men agreed it is acceptable for men to have concurrent partners, but disagreed about whether it is acceptable for women. Third, although men provided many reasons for concurrent partnerships, the most common reasons were that (a) multiple partners fulfill different needs, and (b) it is in a man's nature to have multiple partners. Fourth, men described some (but not all) of the negative consequences of having concurrent partners. Finally, men articulated spoken and unspoken rules that govern concurrent partnerships. These findings increase knowledge about urban, African-American men's attitudes toward concurrent partnerships, and can help to improve the efficacy of sexual risk-reduction interventions for this group of underserved men and their partners.

Fourth, men described some (but not all) of the negative consequences of having concurrent partners. Finally, men articulated spoken and unspoken rules that govern concurrent partnerships. These findings increase knowledge about urban, African-American men’s attitudes toward concurrent partnerships, and can help to improve the efficacy of sexual risk-reduction interventions for this group of underserved men and their partners.

    Our objectives were to: (1) compare multiple measures of partnership concurrency, including the UNAIDS-recommended definition and (2) describe the prevalence and correlates of concurrent sexual partnerships among young Kenyan men. We analyzed 10,907 lifetime partnerships of 1,368 men ages 18-24 years enrolled in a randomized trial of male circumcision to reduce HIV-1 incidence in Kisumu. Partnership concurrency was determined by overlapping dates and examined over varying recall periods and assumptions. The lifetime prevalence of concurrency was 77 %. Sixty-one percent of all partnerships were concurrent and factors associated with concurrency differed by partner type. Point prevalence of concurrency at the time of the interview was consistently the highest and UNAIDS-recommended definition was the most conservative (25 vs. 18 % at baseline, respectively). Estimates of concurrency were influenced by methods for definition and measurement. Regardless of definition, concurrent partnerships are frequent in this population of young, sexually active men in high HIV prevalence Kisumu, Kenya.

    Animal studies have shown that Listeria monocytogenes can probably access the brain through a peripheral intraneural route, and it has been suggested that a similar process may occur in humans. However, thus far, its spreading through the central nervous system (CNS) has not been completely elucidated. The authors present a case of multiple L. monocytogenes cerebral abscesses characterized by a pattern of distribution that suggested spread along white matter fiber tracts and reviewed the literature to identify other cases for analysis. They elected to include only those cases with 3 or more cerebral abscesses to make sure that the distribution was not random, but rather followed a pattern. In addition, they included those cases with abscesses in both the brainstem and the cerebral hemispheres, but excluded cases in which abscesses were located solely in the brainstem. Of 77 cases of L. monocytogenes CNS abscesses found in the literature, 17 involved multiple abscesses. Of those, 6 were excluded for lack of imaging and 3 because they involved only the brainstem. Of the 8 remaining cases from the literature, one was a case of bilateral abscesses that did not follow a fiber tract; another was also bilateral, but with lesions appearing to follow fiber tracts on one side; and in the remaining 6, to which the authors added their own case for a total of 7, all the abscesses were located exclusively in the same hemisphere and distributed along white matter fiber tracts. The findings suggest that after entering the CNS, L. monocytogenes travels within the axons, resulting in a characteristic pattern of distribution of multiple abscesses along the white matter fiber tracts in the brain. This report is the first description suggesting intraaxonal CNS spread of L. monocytogenes infection in humans following its entry into the brain. This distinct pattern is clearly seen on imaging and its recognition may be valuable in the diagnosis of listeriosis. This finding may allow for

    We report a case of multiple duodenal, pancreatic, and gastric carcinoids. A 67-year old woman was admitted to our hospital for treatment of a duodenal carcinoid.Laboratory tests revealed that the patient was associated with macrocytic anemia and hypergastrinemia, and type A gastritis was shown by gastrofiberscopy.During surgery, another tumor was incidentally found in the head of the pancreas. The tumors in the duodenum and pancreas were completely excised by pancreatoduodenectomy and immunohistologically diagnosed as gastrin-and serotonin-producing carcinoids,respectively. Pathological examination revealed that in addition to the grossly found carcinoids, there were subclinical carcinoids, one of which was an endocrine cell micronest, located in the stomach and duodenum.The tumors in the duodenum, pancreas, and stomach showed different characteristics from one another morphologically and immunochemically. Although no definitive evidence has been obtained, some sort of genetic anomaly may have been involved in this case,and hypergastrinemia due to duodenal gastrinoma may induce multiple gastric carcinoids.

    Multiple endocrine neoplasia type 1 (MEN1) is a rare hereditary syndrome known to predispose subjects to endocrine neoplasms in a variety of tissues such as the parathyroid glands, pituitary gland, pancreas and gastrointestinal tract. We herein report a patient with a past history of pituitary adenoma, presenting with symptoms of chronic diarrhea for nearly one year and a sudden upper gastrointestinal hemorrhage as well as perforation without signs. Nodules in the duodenum and in the uncinate process and tail of pancreas and enlargement of the parathyroid glands were detected on preoperative imaging. Gastroscopy revealed significant ulceration and esophageal reflux diseases. The patient underwent subtotal parathyroidectomy and autotransplantation, pylorus-preserving pancreaticoduodenectomy and pancreatic tail resection and recovered well. The results observed in our patient suggest that perforation and bleeding of intestine might be symptoms of Zollinger-Ellison Syndrome in patients with MEN1.

    Bisphosphonates have been commonly used for the treatment of osteoporosis. However, there have been recent case reports of atypical fractures citing their long-term use, which inhibits the turnover of bone components. A 64-year-old woman visited the outpatient clinic with pain in her right thigh and ambulation difficulty. We found fractures at both pedicles of L4 vertebra. subtrochanteric region of right femur, and left femoral shaft upon a radiologic examination. She had taken intravenous ibandronic sodium for osteoporosis over 3 years. We changed the bishophonates to a parathyroid hormone because it was suspected that the multiple fractures were caused by the medication. Further, rehabilitation, including progressive weight bearing, was started. After 3 months of the conservative treatment, she was able to walk independently. In conclusion, it is necessary to evaluate the possibility of atypical fractures in osteoporotic patients when they complain of lower extremity pain and to consider alternative treatments instead of bisphosphonates.

    Painful "jumping stump" is an uncommon but very disturbing complication postamputation. This condition is one of the movement disorder entities resulting from peripheral nerve pathology, often known as "peripherally induced movement disorders." Previously case reports have been written about painful and nonpainful incidence of "jumping stump"; however, only the earliest "jumping stump" article in 1852 suspected that neuromas might influence the involuntary movement. In this study, we describe a 38-year-old man with bilateral transfemoral amputee who suffered from painful "jumping stump" with multiple neuromas confirmed by imaging. He was treated successfully by ultrasound-guided phenol injection into the sciatic neuroma stalks. The pathophysiology of jumping stump and its possible association with neuroma are briefly discussed.

    We describe the case of a young female patient who sustained a radial artery penetration injury from broken glass after falling and was managed only by external compression without arterial repair. Although the patient did not have any reported predisposing factors and the radial artery was normal as well as patent in the angiographic examination, she developed progressive multiple digital ischemia and required subsequent amputation of the gangrenous fingers. The possible mechanism might be an occlusion of the digital arteries originating from the injured radial artery by dispersion of thrombembolic particles distally during the injury as there was sparing of involvement of the ring finger, which wore a ring that restricted the thromboembolic particles from passing distally during the accident. This case revealed that particular attention should be paid to those patients with a radial artery penetration injury to facilitate early detection and implementation of therapy for possible finger ischemia and subsequent gangrene.

    The case of a 64-year-old hunter who was accidentally shot at a distance of 40 meters with a shotgun by a member of hunting group was reported. At the scene, the victim was found dead and showed two bullet wounds in the left lateral chest and thigh, and a penetrated wound in the left knee. Autopsy findings revealed that the former two wounds were discharged from the left side of the body, and the last one in the knee from the right. The assailant and comrades who happened to be on the scene of the accident deposed that the only one shot sound was heard at that time. Whether quite different directions of these three wound tracks could be explained with single shot or multiple ones, we discussed the locus of the bullets in consideration of the posture of the victim.

    Full Text Available This study was designed to determine the frequency and clinical characteristics of myasthenia gravis (MG in a large cohort of Persian patients with multiple sclerosis (MS living in the province of Isfahan. We reviewed the case records of patients with definite MS (McDonald′s criteria registered in the Isfahan MS Society (IMSS for associated MG. Of the 1,718 patients with MS in the registry, six patients were found to have both MS and MG. The prevalence after excluding one patient with insufficient data, was 291 per 100,000 (0.29%, a higher prevalence than the earlier reports. These results may support the hypothesis that MS and MG share some common immunopathogenic mechanisms.

  3. Preparing HEP software for concurrency

    2014-06-01

    The necessity for thread-safe experiment software has recently become very evident, largely driven by the evolution of CPU architectures towards exploiting increasing levels of parallelism. For high-energy physics this represents a real paradigm shift, as concurrent programming was previously only limited to special, well-defined domains like control software or software framework internals. This paradigm shift, however, falls into the middle of the successful LHC programme and many million lines of code have already been written without the need for parallel execution in mind. In this paper we have a closer look at the offline processing applications of the LHC experiments and their readiness for the many-core era. We review how previous design choices impact the move to concurrent programming. We present our findings on transforming parts of the LHC experiment reconstruction software to thread-safe code, and the main design patterns that have emerged during the process. A plethora of parallel-programming patterns are well known outside the HEP community, but only a few have turned out to be straightforward enough to be suited for non-expert physics programmers. Finally, we propose a potential strategy for the migration of existing HEP experiment software to the many-core era.

    Glaucoma is rarely complicated by retinitis pigmentosa (RP). To provide clinical evidences for this rare situation, we report the concurrence of these two diseases in two children of a Chinese family. In the present two-child Chinese family without positive history, the older sister presented with bilateral sector RP and coexisting chronic angle-closure glaucoma,and the brother with bilateral whole RP but without coexisting glaucoma. Clinical evidences in concurrence of variants of RP and glaucoma because of possible different gene mutations from the same genetic background represent a rare situation, which may provide clues for future researches in molecular pathogenesis of these rare diseases.

    Full Text Available Abstract Background Multiple sclerosis (MS is considered an autoimmune disease of the central nervous system and therapeutic inhibition of leukocyte migration with natalizumab, an anti-alpha4 integrin antibody, is highly effective in patients with MS. Recent studies performed in experimental animal models with relevance to human disease suggested a key role for blood-brain barrier damage and leukocyte trafficking mechanisms also in the pathogenesis of epilepsy. In addition, vascular alterations and increased leukocyte accumulation into the brain were recently documented in patients with refractory epilepsy independently on the disease etiology. Case report Here we describe the clinical course of a 24-year-old patient with MS in whom abrupt tonic-clonic generalized seizures manifested at disease onset. Although MS had a more favorable course, treatment with glatiramer acetate and antiepileptic drugs for 7 years had no control on seizure generation and the patient developed severe refractory epilepsy. Interestingly, generalized seizures preceded new MS relapses suggesting that seizure activity may contribute to MS worsening creating a positive feedback loop between the two disease conditions. Notably, treatment with natalizumab for 12 months improved MS condition and led to a dramatic reduction of seizures. Conclusion Our case report suggests that inhibition of leukocyte adhesion may represent a new potential therapeutic approach in epilepsy and complement the traditional therapy with anti-epileptic drugs.

  10. Multiple Congenital Granular Cell Epulis: Case Report and Immunohistochemical Profile with Emphasis on Vascularization

    2015-01-01

    Full Text Available Congenital granular cell epulis is a rare benign soft tissue lesion arising from the alveolar ridge in neonates. A rare case of multiple congenital granular cell epulis is reported, alongside a description of its vascular immunohistochemical profile. A female newborn presented with two exophytic pedunculated red nodules located on the alveolar ridge between the future eruption sites of the incisors and canines of the mandible and maxilla. A conservative surgical excision was performed on the second day of life. Histology revealed proliferation of round granular cells containing an abundant eosinophilic cytoplasm with basophilic nuclei, ranging from round to oval in shape. Numerous blood vessels were also seen. Immunohistochemical analysis of the granular cells revealed positivity for CD68, D2-40, Ki67, VEGF, and FGF and negativity for S100, CD34, and CD105. Immunostaining for CD34, CD105, and D2-40 confirmed the presence of a large number of blood and lymphatic vessels. Although rare, an understanding of this lesion is paramount for correct diagnosis and appropriate treatment. In the present report, the immunohistochemical profile confirmed increased vascularization, proving that these lesions are composed of not only new and preexisting blood vessels, but also lymphatic vessels.

    Full Text Available This case report assessed quality of life, activities of daily living, motor symptoms, functional ability, neuromuscular parameters and mRNA expression of selected genes related to muscle protein synthesis and degradation in a patient with Multiple System Atrophy (MSA. The patient underwent resistance training with instability devices (i.e., bosu, dyna disk, balance disk, Swiss ball for six months twice a week. After the six months training, the patient’s left and right quadriceps muscle cross-sectional area and leg press one-repetition maximum increased 6.4%, 6.8%, and 40%, respectively; the patient’s timed up and go, sit to stand, dynamic balance, and activities of daily living improved 33.3%, 28.6%, 42.3%, and 40.1%, respectively; the patient’s severity of motor symptoms and risk of falls decreased 32% and 128.1%, respectively. Most of the subscales of quality of life demonstrated improvements as well, varying from 13.0% to 100.0%. mRNA expression of mechanogrowth factor and mammalian target of rapamycin increased 12.7-fold and 1.5-fold, respectively. This case report describes likely the first nonpharmacological therapeutic tool that might be able to decrease the severity of motor symptoms and risk of falls, and to improve functional ability, neuromuscular parameters, and quality of the life in a patient with MSA.

    Multiple primary malignant neoplasms (MPMNs) are rarely reported and it is important to give early diagnosis and proper therapy for these patients. Here reported a case of 62-year-old man with concomitant three early stage cancer lesions in upper gastrointestinal tract, all of which were detected by endoscopy. The first one was an llc-type lesion at angular part of stomach under endoscopy, which was histologically confirmed to be a mucosal well-differentiated adenocarcinoma.The patient underwent a standard radical gastrectomy for the lesion after the failure of endoscopic treatment. The other two neoplasms were observed during follow-up and were indicated as early stage lesions by synthesizing information from endoscopy, endoscopic ultrasonography, computed tomography and biopsy. One displayed as a hyperemic patch (3cm×4 cm in size) located at the part of esophagus 27 cm away from the incisor teeth and was proved to be moderately differentiated squamous cancer by histopathological examination. The other was an llc-type lesion (3.0 cm×3.5 cm in size) located at the part of esophagus 36 cm away from the incisor teeth, and the biopsy result showed a poorly differentiated squamous carcinoma. Both the two lesions were treated with radical radiation because the patient refused surgery management. No recurrence of former lesions or occurrence of novel lesions were observed during post-treatment follow-up, suggesting radical radiation might be effective for this patient.

    Full Text Available This study aimed to report the presence of parasites resistant to the most used anthelmintic drugs in sheep in Colombia. Four farms (denominated farm 1, 2, 3 and 4 were selected where the animals were not treated with anthelmintics for two months before the trial. Animals with faecal egg count (FEC above 150 and of different ages were allocated into six groups, each consisting of at least 5 animals. The drugs and dosages used were: ivermectin 1% (0.2 mg/kg, albendazole 25% (5 mg/kg, fenbendazole 10% (5 mg/kg, levamisole 10% (5 mg/kg, and moxidectin 1% (0.2 mg/kg. Anthelmintic efficacy was determined by the FEC reduction test (FECRT with a second sampling 14 days post-treatment. The efficacy of albendazole and fenbendazole at farm 1 was above 95%, which was different from the others farms. The FECRT indicated the presence of multidrug resistance in the other farms where no tested drugs showed activity higher than 79% (albendazole: 0 to 55%, fenbendazole: 51.4 to 76.6%, ivermectin: 67.3 to 93.1%, levamisole: 0 to 78.1%, and moxidectin: 49.2 to 64.1%.Haemonchus contortus was the predominant (96% species, followed by a small presence of Trichostrongylus sp. (3% andCooperia sp. (1%. Therefore, we report for the first time the existence of multiple anthelmintic resistance in gastrointestinal nematodes of sheep in Colombia.

    Detailed manufacturing information about the parts can help designers produce better designs. Detailed manufacturing information is conveyed to the designer through micro-circles within the concurrent design process for machined parts, focusing on instantaneous product design and process planning. The process has three key elements: a hierarchical architecture design of the concurrent process planning system, modeling and reengineering of the concurrent process planning, and modeling of information. The approach is successfully implemented and applied for concurrent design and process planning of some complicated parts.

    1999-01-01

    In his 1992 Ph.D. thesis, "Design and Analysis Techniques for Concurrent Blackboard Systems", John McManus defined several performance metrics for concurrent blackboard systems and developed a suite of tools for creating and analyzing such systems. These tools allow a user to analyze a concurrent blackboard system design and predict the performance of the system before any code is written. The design can be modified until simulated performance is satisfactory. Then, the code generator can be invoked to generate automatically all of the code required for the concurrent blackboard system except for the code implementing the functionality of each knowledge source. We have completed the port of the source code generator and a simulator for a concurrent blackboard system. The source code generator generates the necessary C++ source code to implement the concurrent blackboard system using Parallel Virtual Machine (PVM) running on a heterogeneous network of UNIX(trademark) workstations. The concurrent blackboard simulator uses the blackboard specification file to predict the performance of the concurrent blackboard design. The only part of the source code for the concurrent blackboard system that the user must supply is the code implementing the functionality of the knowledge sources.

    Considering the diversity of methods and tools offered to concurrent engineering, the aspects playing important roles in the concurrent engineering c ontext have been pinpointed as being four core elements which are Activity, Meth od, Object and Information. Based on these four elements, a reference framework called AMOI is proposed to be the guideline for the systematic concurrent produc t design. Using the AMOI reference framework, concurrent product development sys tem can be structured into four function models (including the activity model, m ethod model, object model and information model) which are interconnected with e ach other.

    Full Text Available Duedonal diverticulosis is common in clinical practice. Most of duedonal diverticulosis is located at the second part of duodenum; incidence is reported as 67%, incidence of third and forth part is %20. Multiple diverticulosis of the first part of the duodenum is a rare case. There is not any knowledge togetherness of neurofibromatosis type 1 and duedonal diverticulosis. Here we reported incidentally diagnosed multiple diverticulosis of duodenum that is located in the first part in a neurofibromatosis type 1 patient with multiple neurofibromatosis nodules. Neurofibromatosis could affect various organs. Along the digestive system carcinoid tumors and neuroendocrine tumors are more encountered diseases. Endoscopic examinations and abdominal imaging may be useful for the diagnosis of gastrointestinal coexisting disease in neurofibromatosis type 1 . In conclusion neurofibromatosis type 1 could affect multiple systems and it should evaluate carefully.

    Full Text Available Abstract Background Concurrent platinum-based radiochemotherapy has been recommended as a standard of care in patients with locally advanced squamous cell head and neck carcinomas. Unfortunately, there is a lack of level one evidence on best treatment approach for advanced hypopharyngeal cancer. This report aims to summarize the results of our study on concurrent radiochemotherapy in patients with advanced hypopharyngeal cancer. Methods A retrospective analysis of 41 patients with stage III-IV hypopharyngeal cancer was performed. All patients were treated with three dimensional conformal radiotherapy and received 70 Gy in 35 fractions (2 Gy per fraction, 5 fractions per week. In dependence of the period when radiotherapy was realized, two different treatment techniques were used. Concurrent chemotherapy consisted of cisplatin 30 mg/m2 given on a weekly basis. Results The median age was 52 years (range 29-70. Stage IV disease was recognized in 73.2% of the patients. Complete response rates at the primary site and at the metastatic neck lymph nodes were 68.3% and 36.6%, respectively. A complete composite response was present in 27 patients (65.9%. Median follow-up was 13 months (range 7-36. Distant metastases as initial failure occurred in 7 patients (46.7%. The 2-year local relapse-free survival and regional relapse-free survival rates were 55.2% and 75.8%, respectively. The 2-year locoregional relapse-free survival rate was 51.3%. The 2-year disease-free survival and overall survival rates were 29.3% and 32.8%, respectively. Confluent mucositis was developed in 46.3% of patients. Leucopenia grade 1 was the most frequent hematological toxicity. The median weight loss at the end of treatment was 12% (range 5-21. The worst grade of late toxicity was most commonly pronounced in the skin and in the subcutaneous tissue. Conclusions Based on unsatisfactory results in our study we suggest that the use of sequential radiochemotherapy or chemotherapy

    Science.gov (United States)

    Luu, Van T

    2014-01-01

    Introduction: Gout is a common metabolic disorder resulting from supersaturation of uric acid in extracellular fluid and deposition of monosodium urate monohydrate crystals in tissues triggering inflammatory response. Depositions of uric acid crystal outside articular structures cause tophi and are commonly found at peripheral areas of the body which have a lower temperature. Deposition of uric acid crystals in the central area of the body is not uncommon and may be overlooked. Case presentation: A 55-year-old Pacific Islander man with a history of chronic tophaceous gout was admitted because of acute right knee pain. Physical examination revealed signs of inflammation over the right knee. Arthrocentesis was performed but no synovial fluid obtained. The patient was empirically treated with prednisone, colchicine, and febuxostat. On the next day, there was progression of inflammation up to the right mid-thigh. MRI of the right femur was obtained to exclude abscess and necrotizing faciitis. Multiple pockets of abscesses were identified within the vastus medialis and vastus intermedius adjacent to the femoral shaft. This prompted immediate surgical consultation and incision and drainage. Intraoperative findings revealed healthy muscles and deposition of soft-tan material in the vastus medialis and vastus intermedius along and above the shaft of the femur. Culture of the surgical aspirate was negative and pathology showed needle-shaped structures consistent with uric acid crystals. Empiric antibiotic was discontinued. The patient's condition improved after treatment for acute gout. Pegloticase was also added to the treatment regimen during an outpatient follow up visit with his rheumatologist. At six month follow up, the patient reported excellent improvements in clinical symptoms. Discussion: Atypical presentations of chronic tophaceous gout can be a great mimicker, causing diagnostic challenges for clinicians. Our patient who had multiple intramuscular tophi

    Full Text Available Background and Objective: Healthcare-associated infections (HAIs are the main cause of death in hospitalized individuals worldwide, related with preexisting disease and invasive procedures. The present study aimed to identify the microorganisms in a immunosuppressed patient and their antimicrobial resistance profile. Case report: A 33-year-old man with Crohn's disease was admitted in a hospital for an enterostomy and cholecystectomy, with postoperative fever and gastrointestinal bleeding. Infections of the urinary tract, into the bloodstream and associated with vascular catheter were evaluated by collect of urine, blood and secretions from catheter tips, individually plated on specific media for direct identification and antibiogram in VITEK® 2. Two different vascular catheters samples and a hemoculture revealed Staphylococcus aureus strains β-lactamases producers, with macrolide-lincosamide-streptogramin B (MLS B and methicillin resistance phenotypes (MRSA, and one indication of VISA (Vancomycin-intermediate S. aureus. Pseudomonas aeruginosa and P. luteola were detected in catheter tips with different resistance profile, whereas Trichosporon asahii and Klebsiella pneumonia (ciprofloxacin/levofloxacin resistant were isolated from urine. Amikacin, meropenem polymyxin B, piperacillin/tazobactam, ciprofloxacin, cefepime and amphotericin B were administered to this patient. Conclusions: The patient survived even after multiple infections with pathogens usually envolved in HAIs and mortality in brazilian hospitals.

  4. Possible applications of Neuromuscular Taping in pain reduction in Multiple Sclerosis subject: a preliminary report

    Full Text Available Pain is a common disabling symptom in patients with Multiple Sclerosis (MS. It has been indicated that pain prevalence in MS patients is between 29–86 %. It is evident that most MS patients requiring treatment will be also searching pain related treatments to assist in day to day activities. Neuropathic pain is a difficult symptom and is generally inadequately relieved even though different rehabilitative approaches may be used. Neuromuscular Taping inducing micro-movements by stimulating receptors in the skin has been described in literature as a possible intervention in neurological and orthopedic rehabilitation improving mobility and in pain reduction. The aim of this preliminary report was to analyze the effect and to evaluate the possible applications of Neuromuscular Taping (NMT in patients with MS in order to reduce pain in comparison to the Transcutaneous Electrical Nerve Stimulation (TENS and to physical rehabilitation treatment alone. We observed that NMT together with standard physical rehabilitation was able to reduce neuropathic pain to greater lengths, with statistically significant differences between pre and post treatment, compared to the other treatments evaluated. This study showed increased efficacy in pain reduction when NMT was applied to standard physical treatment in long standing pain conditions. Neuromuscular Taping may constitute a low cost treatment strategy for neuropathic pain conditions in MS.

    Acute disseminated encephalomyelitis (ADEM) complicating dengue infection is still exceedingly rare even in endemic countries such as Malaysia. Here we report two such cases, the first in an elderly female patient and the second in a young man. Both presented with encephalopathy, brainstem involvement and worsening upper and lower limb weakness. Initial magnetic resonance imaging (MRI) of the brain was normal in the first case. Serum for dengue Ig M and NS-1 was positive in both cases. Cerebrospinal fluid (CSF) showed pleocytosis in both with Dengue IgM and NS-1 positive in the second case but not done in the first. MRI brain showed changes of perpendicular subcortical palisading white matter, callosal and brainstem disease mimicking multiple sclerosis (MS) in both patients though in the former case there was a lag between the onset of clinical symptoms and MRI changes which was only clarified on reimaging. The temporal evolution and duration of the clinical symptoms, CSF changes and neuroimaging were more suggestive of Dengue ADEM rather than an encephalitis though initially the first case began as dengue encephalitis. Furthermore in dengue encephalitis neuroimaging is usually normal or rarely edema, haemorrhage, brainstem, thalamic or focal lesions are seen. Therefore, early recognition of ADEM as a sequelae of dengue infection with neuroimaging mimicking MS and repeat imaging helped in identifying these two cases. Treatment with intravenous steroids followed by maintenance oral steroids produced good outcome in both patients. Copyright © 2016 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Introduction Neurological complications leading to morbidity and mortality are not frequent in renal transplant recipients. Here, we report a renal transplant recipient who presented with diminished strength in his limbs probably due to multiple etiologies of axonal sensorimotor polyneuropathy, which resolved with intravenous immunoglobulin. Case presentation A 49-year-old Iranian male renal transplant recipient with previous history of autosomal dominant polycystic kidney disease presented with diminished strength in his limbs one month after surgery. Our patient was on cyclosporine A, mycophenolate mofetil and prednisone. Although a detected hypophosphatemia was corrected with supplemental phosphate, the loss of strength was still slowly progressive and diffuse muscular atrophy was remarkable in his trunk, upper limb and pelvic girdle. Meanwhile, his cranial nerves were intact. Post-transplant diabetes mellitus was diagnosed and insulin therapy was initiated. In addition, as a high serum cyclosporine level was detected, the dose of cyclosporine was reduced. Our patient was also put on intravenous ganciclovir due to positive serum cytomegalovirus immunoglobulin M antibody. Despite the reduction of oral cyclosporine dose along with medical therapy for the cytomegalovirus infection and diabetes mellitus, his muscular weakness and atrophy did not improve. One week after administration of intravenous immunoglobulin, a significant improvement was noted in his muscular weakness. Conclusion A remarkable response to intravenous immunoglobulin is compatible with an immunological basis for the present condition (post-transplant polyneuropathy. In cases of post-transplant polyneuropathy with a high clinical suspicion of immunological origin, administration of intravenous immunoglobulin may be recommended.

    In the present study, the case of a 41-year-old man with immunoglobulin (Ig)M multiple myeloma (MM) that presented with an unusually non-aggressive clinical course who has survived for >9 years to date, is presented. Initial diagnosis of symptomatic MM was established according to the International Myeloma Working Group consensus statement and guidelines. Due to the mild symptoms, no therapy was administered and the patient was closely followed up. Eight years after initial diagnosis, clinical, morphological and genetic progression occurred with the development of hypercalcemia, progressively deteriorating polyneuropathy, clonal expansion of plasma cells up to 50% of hematopoietic cells and demonstration of the typical t(11;14) translocation (Ig heavy chain locus rearrangement). Subsequently, 4 cycles of induction chemotherapy with velcade, cyclophosphamide and dexamethasone, were administered. At the time of writing, the patient remained alive in generally good health. To the best of our knowledge, with a survival time of >9 years, this case reports the longest survival time of an IgM MM patient to date, which contradicts previous evidence that suggests IgM MM exhibits an aggressive clinical course.

    2002-01-01

    Full Text Available A thirty three year-old, male patient was admitted at the Hospital of the São Paulo University School of Medicine, at the city of São Paulo, Brazil, with complaint of pains, tingling and decreased sensibility in the right hand for the last four months. This had progressed to the left hand, left foot and right foot, in addition to a difficulty of flexing and stretching in the left foot. Tests were positive for HBeAg, IgM anti-HBc and HBsAg, thus characterizing the condition of acute hepatitis B. The ALT serum level was 15 times above the upper normal limit. Blood glucose, cerebral spinal fluid, antinuclear antibodies (ANA and anti-HIV and anti-HCV serum tests were either normal or negative. Electroneuromyography disclosed severe peripheral neuropathy with an axon prevalence and signs of denervation; nerve biopsy disclosed intense vasculitis. The diagnosis of multiple confluent mononeuropathy associated to acute hepatitis B was done. This association is not often reported in international literature and its probable cause is the direct action of the hepatitis B virus on the nerves or a vasculitis of the vasa nervorum brought about by deposits of immune complexes.

    Explosives create and energize particles that act as projectiles prone to further fragmentation or create other secondary missiles in the body. These fragments may result in secondary injuries. This has been repeatedly described in the orthopedic and neurosurgical literature. We report the same process for abdominal injuries after fascial penetration in the military setting. This is an observational case series study. Local wound exploration as a standard approach was performed in conscious patients who sustained abdominal wall injuries. Patients with negative physical examination were excluded from the study. An intraperitoneal injury was assumed in those with a full-thickness fascial defect, and laparotomy was performed. Twenty patients met the study eligibility criteria. Of those 20 patients, 12 had negative wound exploration and were excluded from the study, while abdominal organ injuries were found in eight (40%) patients. During laparotomy, projectile-induced injuries in a sprayed distribution were found in three (38%) of these patients. These injuries were far from the predictable trajectory and in the absence of bone fragmentation. The overall mean number of peritoneal defects was 1.7, and a mean 6.8 intra-abdominal injuries for each peritoneal defect were found when through-and-through injuries were excluded.Despite a single peritoneal defect, there may be multiple intraperitoneal injuries due to further fragmentation of the projectile. Under mass casualties, wound exploration with a full-thickness fascial defect could serve as an indicator of possible intra-abdominal injuries, and consequently indicate exploratory laparotomy.

    Multiple sclerosis (MS) is a demyelinating disease of the central nervous system, characterized by focal neurological dysfunction with a relapsing and remitting course. Tumor-like presentation of MS (or "tumefactive"/"pseudotumoral" presentation) has been described before with a certain frequency; it consists of a large single plaque (>2cm) with presence of edema and mass effect and it is hard to distinguish from a brain tumor. However, we present a very rare case of a 53-year-old woman with a right temporal mass that turned out to be a MS plaque, who deteriorated within hours (brain herniation with loss of consciousness and unilateral mydriasis) and required an emergency craniotomy. We also present a review of the literature. It appears that only 4 cases of emergency craniotomy/craniectomy required in a patient with a tumor-like MS plaque have been reported before.

    Full Text Available Abstract Background Delayed-onset heparin-induced thrombocytopenia with thrombosis, albeit rare, is a severe side effect of heparin exposure. It can occur within one month after coronary artery bypass grafting (CABG with manifestation of different thrombotic events. Case presentation A 59-year-old man presented with weakness, malaise, bilateral lower limb pitting edema and a suspected diagnosis of deep vein thrombosis 18 days after CABG. Heparin infusion was administered as an anticoagulant. Clinical and paraclinical work-up revealed multiple thrombotic events (stroke, renal failure, deep vein thrombosis, large clots in heart chambers and 48 ×103/μl platelet count, whereupon heparin-induced thrombocytopenia was suspected. Heparin was discontinued immediately and an alternative anticoagulant agent was administered, as a result of which platelet count recovered. Heparin-induced thrombocytopenia, which causes thrombosis, is a serious side effect of heparin therapy. It is worthy of note that no case of delayed-onset heparin-induced thrombocytopenia with thrombosis associated with cardiopulmonary bypass surgery has thus far been reported in Iran. Conclusion Delayed-onset heparin-induced thrombocytopenia should be suspected in any patient presenting with arterial or venous thromboembolic disorders after recent heparin therapy, even though the heparin exposure dates back to more than a week prior to presentation; and it should be ruled-out before the initiation of heparin therapy.

    Multiple myeloma (MM) is characterized by a clonal proliferation of plasma cells. Although the bone marrow is the usual site of involvement, extramedullary plasmacytomas (EMPs) also occur, affecting any tissue. Cardiac and pericardial involvement, although described, have been rare occurrences. We present the case of a 61-year-old female patient 47 days after autologous stem cell transplant for MM who developed cardiac tamponade owing to extramedullary recurrence of myeloma, pulmonary embolism, and takotsubo cardiomyopathy. We performed a review of the published studies of all cases of MM presenting at diagnosis or relapse with cardiac or pericardial involvement in the past 25 years. Including our patient, 34 patients with plasmacytoma involving cardiac or pericardial structures were identified from the literature search. Approximately equal numbers of patients were male and female (42% and 57%, respectively). The mean age was 62 years. Primary plasmacytomas accounted for 12% of the cases. A history of MM, EMP, or monoclonal gammopathy of uncertain significance was noted in two thirds of the cases (66.6%). Treatment included chemotherapy and/or high-dose corticosteroids in 81.1% of cases and 27% underwent radiation therapy. The reporting of all cases to date has focused on unusual findings, rather than treatment approaches or new therapeutic strategies that might benefit patients. We suggest the formation of a database of all cases of cardiac and pericardial EMPs, with a focus on predictive disease variables, standardized staging, outcomes, and survival, to ensure that patients are optimally treated in the modern era.

    The ATLAS experiment has successfully used its Gaudi/Athena software framework for data taking and analysis during the first LHC run, with billions of events successfully processed. However, the design of Gaudi/Athena dates from early 2000 and the software and the physics code has been written using a single threaded, serial design. This programming model has increasing difficulty in exploiting the potential of current CPUs, which offer their best performance only through taking full advantage of multiple cores and wide vector registers. Future CPU evolution will intensify this trend, with core counts increasing and memory per core falling. Maximising performance per watt will be a key metric, so all of these cores must be used as efficiently as possible. In order to address the deficiencies of the current framework, ATLAS has embarked upon two projects: first, a practical demonstration of the use of multi-threading in our reconstruction software, using the GaudiHive framework; second, an exercise to gather requirements for an updated framework, going back to the first principles of how event processing occurs. In this paper we report on both these aspects of our work. For the hive based demonstrators, we discuss what changes were necessary in order to allow the serially designed ATLAS code to run, both to the framework and to the tools and algorithms used. We report on what general lessons were learned about the code patterns that had been employed in the software and which patterns were identified as particularly problematic for multi-threading. These lessons were fed into our considerations of a new framework and we present preliminary conclusions on this work. In particular we identify areas where the framework can be simplified in order to aid the implementation of a concurrent event processing scheme. Finally, we discuss the practical difficulties involved in migrating a large established code base to a multi-threaded framework and how this can be achieved

  15. Concurrent partnerships and HIV: an inconvenient truth

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available Abstract The strength of the evidence linking concurrency to HIV epidemic severity in southern and eastern Africa led the Joint United Nations Programme on HIV/AIDS and the Southern African Development Community in 2006 to conclude that high rates of concurrent sexual partnerships, combined with low rates of male circumcision and infrequent condom use, are major drivers of the AIDS epidemic in southern Africa. In a recent article in the Journal of the International AIDS Society, Larry Sawers and Eileen Stillwaggon attempt to challenge the evidence for the importance of concurrency and call for an end to research on the topic. However, their "systematic review of the evidence" is not an accurate summary of the research on concurrent partnerships and HIV, and it contains factual errors concerning the measurement and mathematical modelling of concurrency. Practical prevention-oriented research on concurrency is only just beginning. Most interventions to raise awareness about the risks of concurrency are less than two years old; few evaluations and no randomized-controlled trials of these programmes have been conducted. Determining whether these interventions can help people better assess their own risks and take steps to reduce them remains an important task for research. This kind of research is indeed the only way to obtain conclusive evidence on the role of concurrency, the programmes needed for effective prevention, the willingness of people to change behaviour, and the obstacles to change.

    1994-03-01

    A case is presented of an individual with Down's syndrome and multiple personality disorder. No such cases were found in a review of the literature. Three other individuals with Down's syndrome are also discussed whose symptoms range from experiencing imaginary friends to experiencing borderline multiple personality disorder. In all these cases the imaginary friends became more evident and resistive of diversion as the levels of stress increased. We speculate that experiencing imaginary friends progresses to experiencing multiple personality disorder in some individuals as personal stress increases. These cases also indicate that limited cognitive development does not preclude individuals from presenting with imaginary friends or multiple personality disorder.

  6. Multiparty Compatibility for Concurrent Objects

    Directory of Open Access Journals (Sweden)

    Roly Perera

    2016-06-01

    Full Text Available Objects and actors are communicating state machines, offering and consuming different services at different points in their lifecycle. Two complementary challenges arise when programming such systems. When objects interact, their state machines must be "compatible", so that services are requested only when they are available. Dually, when objects refine other objects, their state machines must be "compliant", so that services are honoured whenever they are promised. In this paper we show how the idea of multiparty compatibility from the session types literature can be applied to both of these problems. We present an untyped language in which concurrent objects are checked automatically for compatibility and compliance. For simple objects, checking can be exhaustive and has the feel of a type system. More complex objects can be partially validated via test cases, leading to a methodology closer to continuous testing. Our proof-of-concept implementation is limited in some important respects, but demonstrates the potential value of the approach and the relationship to existing software development practices.

    2013-01-01

    Full Text Available Multiple intracranial meningiomas are a condition where there is more than one meningioma in several intracranial locations in the same patient without signs of neurofibromatosis. Incidence varies from 1 to 10%. The prognosis of multiple intracranial meningioma does not differ from benign solitary meningiomas despite the multiplicity. However, the simultaneous occurrence of different grades of malignancy is observed in one-third of multiple meningiomas. Surgery remains the best option for treatment of symptomatic lesions. Our case review aims to present and discuss a 75-year-old female patient diagnosed with multiple intracranial meningiomas, describing their clinical, radiological, histological characteristics. It also highlights the fact that the patient had two tumours, underwent surgery, and so far has a good quality of life.

    Full Text Available We report a case of a 44-years-old woman with relapsing-remitting and secondarily progressive form of multiple sclerosis (MS since aged 24 years, who developed an anaplastic astrocytoma. The neurological manifestations of the tumor were misinterpreted as resulting from MS. Sequential MRI examination and seizures raised the possibility of another nature of her symptoms, besides MS. Her initial good response to high doses corticosteroids led to the initial assumption her symptoms were only exclusively due to the demyelinating process. She underwent craniotomy with radical excision of the lesion. Pathological examination disclosed anaplastic astrocytoma. Other cases of coincidental MS and primary CNS tumors are reviewed, as well as their possible relation.Relatamos o caso de uma paciente de 44 anos, portadora de esclerose múltipla forma surto-remissão e progressiva secundária, que na evolução desenvolveu um astrocitoma anaplásico.

    Full Text Available Milija D Mijajlović,* Vuk M Aleksić,* Nadežda M Čovičković Šternić Department for Cerebrovascular Disorders and Headaches, Neurology Clinic, Clinical Center of Serbia, School of Medicine, University of Belgrade, Belgrade, Serbia *These authors contributed equally to this work Abstract: Cluster headache (CH is estimated to be the most common primary trigeminal autonomic headache, although it is a rare disabling medical condition. Dominant symptoms of CH include severe unilateral orbital, supraorbital, and/or temporal pain, lasting from 15 to 180 minutes if untreated, associated with at least one of various autonomic symptoms during the headache, such as conjunctival injection, lacrimation, nasal congestion and rhinorrhea, facial sweating, miosis, ptosis, and eyelid edema. Headache is not frequently a symptom of multiple sclerosis (MS. The most commonly reported primary headaches are migraine without aura and a tension-type headache. Several described cases involved complicated migraine, ophthalmoplegic migraine-like headache, and finally cluster-like headache. We present a case of a 45-year-old male patient who had typical CH attacks as the initial and only clinical manifestation of MS, which was diagnosed after cerebrospinal fluid (CSF isoelectric focusing and brain magnetic resonance imaging (MRI investigation. He presented as a typical cluster-like headache patient since in the background of the CH symptoms and signs, were MS demyelinating lesions. In a patient with CH symptoms one should always think about the possibility of cluster-like-headache, which presents the CH patient with different underlying diseases, so we proposed a protocol to evaluate such patients and exclude diseases that could be in the background of CH symptoms.

    Full Text Available In recent years, managing the interface between design and other activities has received considerable attention. Effective coordination among these areas is therefore vital for effectiveness of the organization. The ideal situation would be continuous interdepartmental contact with well-developed channels of communication. In this study, the best strategy for product design department has been chosen using the strategic formulation framework with fuzzy approach. Subsequently, alignment of each functional design strategy with SAPCO business strategies has been explained. Findings indicate that developing partnerships with global automotive and engineering design companies and building strategic alliances with rival firms to achieve competitive advantages have maximum alignment with business strategies. In addition, findings provide a basis for firms in evaluating the concurrent design strategies and a reference for them to strengthen their concurrent capabilities. There are few reports on sustained use of concurrent design as an on-going strategic process in an organization. This study aims at contributing to the concurrent design solutions.

    2013-12-01

    We report a case of papillary carcinoma of the thyroid gland and cervical lymph node metastases with concurrent tuberculous lymphadenitis that was diagnosed preoperatively. A 35-year-old woman presented with multiple lymph node swellings and an anterior neck mass. No findings suggesting the coexistence of pulmonary tuberculosis were present. The patient underwent a total thyroidectomy with bilateral neck dissection together with medication. Measures to prevent tuberculosis were undertaken during the perioperative period. The histopathological diagnosis was papillary carcinoma with both metastatic and tuberculous lymphadenitis of the lymph nodes in the neck. The possible coexistence of tuberculous lymphadenitis must be ruled out when lymph node swellings are observed in patients with head and neck cancer, including thyroid carcinoma.

    2014-12-01

    Empirical estimates of the association between concurrent partnerships (CP) and HIV risk are affected by non-sampling errors in survey data on CPs, e.g., because respondents misreport the extent of their CPs. We propose a new approach to measuring CPs in couples, which permits assessing how respondent errors affect estimates of the association between CPs and HIV risk. Each couple member is asked (1) to report whether s/he has engaged in CPs and (2) to assess whether his/her partner has engaged in CPs, since their couple started. Cross-tabulating these data yields multiple classifications (with varying combinations of sensitivity/specificity) of the CPs of each couple member. We then measure the association between CPs and HIV outcomes according to each classification. The resulting range of estimates is an indicator of the uncertainty associated with respondent errors. We tested this approach using data on 520 matched couples drawn from the Likoma Network Study. Results suggest that existing tests of the concurrency hypothesis are affected by significant uncertainty.

    Plasma cell neoplasms are categorized by neoplastic proliferation of a single clone of plasma cells which produce a monoclonal immunoglobulin. Plasma cell neoplasms can present as a solitary plasmacytoma or as multiple myeloma. Both of them can progress to multiple myeloma. Once a diagnosis of plasmacytoma has been made, thorough examinations should be carried out for identifying the disease entity. Herein, we describe an extraordinary rare case of multiple myeloma with initial presentation of a left sphenoid neoplasm resulting in left-sided headache and rapid deterioration of visual acuity. Histo-pathologic analysis revealed a plasma cell neoplasm with positive immunostaining for cluster of differentiation (CD)138, CD79a, and kappa light chain of immunoglobulin. A bone marrow aspiration was then performed, and the diagnosis of multiple myeloma was then confirmed. After investigative workup, our patient received chemotherapy, localized radiotherapy, and autologous stem cell transplantation. Her visual acuity recovered to the baseline and she sustained a partial response without subjective discomfort. Extramedullary plasmacytoma is an interesting but infrequent presentation of multiple myeloma. Moreover, involvement of the sphenoid sinus in multiple myeloma resulting in extrinsic optic nerve compression is extremely rare. Clinicians should consider plasmacytoma as a diagnostic possibility when presented with cases of solitary sphenoid neoplasm and rapid progression of clinical course.

    Syphilis, a chronic multisystem disease, is caused by a spirochete, Treponema pallidum. Clinical presentation may expand to several stages including primary, secondary and latent syphilis, which may present as early or late syphilis. Nephrotic syndrome and acute hepatitis are well-known complications of secondary syphilis. To the best of our knowledge, secondary syphilis with coexisting renal and hepatic complications has rarely been reported. Here we present a rare case of concurrent nephrotic syndrome and acute hepatitis in a patient with secondary syphilis.

    Gastrointestinal stromal tumors (GISTs) are rare tumors,which represent approximately 1% of the neoplasms of the gastrointestinal tract. These tumors rarely give extra-abdominal metastases. However, their clinical outcome is potentially adverse. In some rare cases, coexistance of GISTs with other malignancies has been reported. Here we present a case of a 74-year old male with GIST, which was managed by surgical resection.Fourteen months later, the patient presented with liver metastases and imatinib mesylated was administered.During treatment, the patient reported skeletal pain and plane X-rays revealed osteolytic bone lesions. Further investigation revealed the presence of multiple myeloma.To the best of our knowledge, this is the first report of the co-existence of multiple myeloma (MM) with GIST.

    Full Text Available Abstract Background We report a case of mucormycosis in a healthy 17-year-old accident victim with multiple abdominal injuries which was caused by infection with Absidia Corymbifera, a ubiquitous saphrophyte in the ground. Case presentation The patient was admitted to hospital with massive abdominal trauma. During an 8-hour emergency operation he received transfusions of compacted red blood cells, plasma, platelets and hemagel. He developed a crush syndrome with acute renal failure, resolved with extra-corporeal dialysis and had to undergo splenectomy because of spleen hematoma. As wound secretion and central venous catheter (CVC blood cultures and drainage fluid were positive for Enterococcus Faecium, Providentia Rettgeri, Hafnia Alvei and Candida Albicans, tecoplanin, metronidazole, imipenem, and flucanozole were administered. Although the CVC was changed high fever persisted and discharge continued from the large abdominal wound. Repeated tampons in different sections and wound secretion smears were positive for A. corymbifera. Flucanozole was stopped and liposomal amphotericin (Ambisome; 5 mg/Kg i.v. given for over 3 months. The patient improved; fever gradually disappeared. After 8 days, tampons and wound secretion smears were negative for A. corymbifera. No other fungal infections developed.

    2011-03-01

    Full Text Available Abstract Multiple diverticulosis of jejunum represents an uncommon pathology of the small bowel. The disease is usually asymptomatic and must be taken into consideration in cases of unexplained malabsorption, anemia, chronic abdominal pain or discomfort. Related complications such as diverticulitis, perforation, bleeding or intestinal obstruction appear in 10-30% of the patients increasing morbidity and mortality rates. We herein report a case of a 55 year-old man presented at the emergency department with acute abdominal pain, vomiting and fever. Preoperative radiological examination followed by laparotomy revealed multiple giant jejunal diverticula causing intestinal obstruction. We also review the literature for this uncommon disease.

  11. Concurrent infection of Japanese encephalitis and mixed plasmodium infection

    2012-01-01

    Full Text Available Japanese encephalitis (JE and malaria would coexist in the areas where both illnesses are endemic with overlapping clinical pictures, especially in a case of febrile encephalopathy with hepatosplenomegaly. However, there are no published data till date showing concurrent infection of these two agents despite both diseases being coendemic in many areas. We report a case of concurrent infection of JE and mixed plasmodium infection, where the case, initially diagnosed as cerebral malaria did not improve on antimalarials and alternative diagnosis of JEV encephalitis was thought which was confirmed by a serological test. To the best of our knowledge, this is the first case report of concurrent Japanese encephalitis with mixed plasmodium infection. We report a case of 3-year-old male child, who presented with febrile encephalopathy with hepatosplenomegaly. Based on a rapid diagnostic test and peripheral smear examination, a diagnosis of mixed P.Vivax and P.falciparum infection was made and the patient was treated with quinine and doxycycline. However, besides giving antimalarials the patient did not improve and an alternative diagnosis of JE was considered as the patient was from the endemic zone of Japanese encephalitis. Cerebrospinal fluid (CSF of the patient was sent for a virological study which came out to be positive for JE IgM in CSF, which is confirmatory of JE infection. In a patient with febrile encephalopathy with hepatosplenomegaly especially in areas coendemic for JE and malaria, the possibility of mixed infection should be kept in mind.

  12. Similarity based mixed transaction concurrency control protocol

    Institute of Scientific and Technical Information of China (English)

    PAN Yi; LU Yan-sheng

    2005-01-01

    Due to the various performance requirements and data access restrictions of different types of real-time transactions, concurrency control protocols which had been designed for the systems with single type of transactions are not sufficient for mixed real-time database systems (MRTDBS), where different types of real-time transactions coexist in the systems concurrently. In this paper, a new concurrency control protocol MRTT_CC for mixed real-time transactions is proposed. The new strategy integrates with different concurrency control protocols to meet the deadline requirements of different types of real-time transactions. The data similarity concept is also explored in the new protocol to reduce the blocking time of soft real-time transactions, which increases their chances to meet the deadlines. Simulation experiments show that the new protocol has gained good performance.

  14. Strategy Improvement for Concurrent Safety Games

    CERN Document Server

    Chatterjee, Krishnendu; Henzinger, Thomas A

    2008-01-01

    We consider concurrent games played on graphs. At every round of the game, each player simultaneously and independently selects a move; the moves jointly determine the transition to a successor state. Two basic objectives are the safety objective: ``stay forever in a set F of states'', and its dual, the reachability objective, ``reach a set R of states''. We present in this paper a strategy improvement algorithm for computing the value of a concurrent safety game, that is, the maximal probability with which player 1 can enforce the safety objective. The algorithm yields a sequence of player-1 strategies which ensure probabilities of winning that converge monotonically to the value of the safety game. The significance of the result is twofold. First, while strategy improvement algorithms were known for Markov decision processes and turn-based games, as well as for concurrent reachability games, this is the first strategy improvement algorithm for concurrent safety games. Second, and most importantly, the impro...

  16. CilkSpec: Optimistic Concurrency for Cilk

    Energy Technology Data Exchange (ETDEWEB)

    Aga, Shaizeen D.; Krishnamoorthy, Sriram; Narayanasamy, Satish

    2015-11-15

    Recursive parallel programming models such as Cilk strive to simplify the task of parallel programming by enabling a simple divide-and-conquer model of programming. This model is effective in re- cursively partitioning work into smaller parts and combining their results. However, recursive work partitioning can impose additional constraints on concurrency than is implied by the true dependences in a program. In this paper, we present a speculation-based approach to alleviate the concurrency constraints imposed by such recursive parallel programs. We design a runtime infrastructure that supports speculative execution and a predictor to accurately learn and identify opportunities to relax extraneous concurrency constraints. Experimental evaluation demonstrates that speculative relaxation of concurrency constraints can deliver gains of up to 1.6× on 30 cores over baseline Cilk.

  17. Heterogeneous concurrent computing with exportable services

    Sunderam, Vaidy

    1995-01-01

    Heterogeneous concurrent computing, based on the traditional process-oriented model, is approaching its functionality and performance limits. An alternative paradigm, based on the concept of services, supporting data driven computation, and built on a lightweight process infrastructure, is proposed to enhance the functional capabilities and the operational efficiency of heterogeneous network-based concurrent computing. TPVM is an experimental prototype system supporting exportable services, thread-based computation, and remote memory operations that is built as an extension of and an enhancement to the PVM concurrent computing system. TPVM offers a significantly different computing paradigm for network-based computing, while maintaining a close resemblance to the conventional PVM model in the interest of compatibility and ease of transition Preliminary experiences have demonstrated that the TPVM framework presents a natural yet powerful concurrent programming interface, while being capable of delivering performance improvements of upto thirty percent.

  18. Abstract Diagnosis for Timed Concurrent Constraint programs

    CERN Document Server

    Comini, Marco; Villanueva, Alicia

    2011-01-01

    The Timed Concurrent Constraint Language (tccp in short) is a concurrent logic language based on the simple but powerful concurrent constraint paradigm of Saraswat. In this paradigm, the notion of store-as-value is replaced by the notion of store-as-constraint, which introduces some differences w.r.t. other approaches to concurrency. In this paper, we provide a general framework for the debugging of tccp programs. To this end, we first present a new compact, bottom-up semantics for the language that is well suited for debugging and verification purposes in the context of reactive systems. We also provide an abstract semantics that allows us to effectively implement debugging algorithms based on abstract interpretation. Given a tccp program and a behavior specification, our debugging approach automatically detects whether the program satisfies the specification. This differs from other semiautomatic approaches to debugging and avoids the need to provide symptoms in advance. We show the efficacy of our approach...

  19. Creatine and Caffeine: Considerations for Concurrent Supplementation.

    Science.gov (United States)

    Trexler, Eric T; Smith-Ryan, Abbie E

    2015-12-01

    Nutritional supplementation is a common practice among athletes, with creatine and caffeine among the most commonly used ergogenic aids. Hundreds of studies have investigated the ergogenic potential of creatine supplementation, with consistent improvements in strength and power reported for exercise bouts of short duration (≤ 30 s) and high intensity. Caffeine has been shown to improve endurance exercise performance, but results are mixed in the context of strength and sprint performance. Further, there is conflicting evidence from studies comparing the ergogenic effects of coffee and caffeine anhydrous supplementation. Previous research has identified independent mechanisms by which creatine and caffeine may improve strength and sprint performance, leading to the formulation of multi-ingredient supplements containing both ingredients. Although scarce, research has suggested that caffeine ingestion may blunt the ergogenic effect of creatine. While a pharmacokinetic interaction is unlikely, authors have suggested that this effect may be explained by opposing effects on muscle relaxation time or gastrointestinal side effects from simultaneous consumption. The current review aims to evaluate the ergogenic potential of creatine and caffeine in the context of high-intensity exercise. Research directly comparing coffee and caffeine anhydrous is discussed, along with previous studies evaluating the concurrent supplementation of creatine and caffeine.

    Although malignant transformation to chondrosarcoma may occur in some patients with multiple enchondromatosis, this event rarely occurs in the hand. We encountered two patients with chondrosarcoma of the hand secondary to multiple enchondromatosis. One patient was a 27-year-old man and the other, a 76-year-old man. Both patients manifested multiple osteolytic lesions in the hand on the plain radiographs. Severe bone destruction associated with a large soft-tissue swelling of the proximal and middle phalanges of the little finger was seen in case 1. In case 2, tremendous expansion and bone destruction of the middle phalanx of the ring finger was seen. Magnetic resonance images of the tumour in both patients showed low signal intensity on T1-weighted and high signal intensity on T2-weighted images. Amputation was performed in each patient. Histological examination revealed that the tumour was a grade 2 chondrosarcoma in case 1 and a grade 1 chondrosarcoma in case 2 accompanied by enchondromata. From these findings, the diagnosis of chondrosarcoma secondary to multiple enchondromatosis was made. Because quite a few patients with multiple enchondromatosis develop secondary chondrosarcoma, although rarely in the hand, the enchondromata should be curetted, unless impractical, before malignant transformation occurs.

  1. Concomitant multiple myeloma spectrum diagnosis in a central retinal vein occlusion: a case report and review.

    Science.gov (United States)

    Borgman, Christopher J

    2016-07-01

    Multiple myeloma is a neoplastic plasma-cell disorder resulting from malignant plasma cells in the bone marrow. It can cause a hyperviscosity syndrome secondary to the paraproteinaemia associated with the disease. The increased hyperviscosity can lead to retinal vein occlusions and other ocular problems that may challenge clinicians. In patients with multiple myeloma and hypertension and/or diabetes mellitus, retinal changes appear similar and changes due to one disease or the other may be difficult to determine. A 48-year-old white female presented to the clinic with a complaint of blurry vision in her left eye. A full comprehensive ocular examination revealed a central retinal vein occlusion presumably from the patient's history of hypertension, diabetes mellitus and hypercholesterolaemia. Further bloodwork revealed monoclonal protein in the patient's serum and an increased percentage of plasma cells in the bone marrow. She was diagnosed with monoclonal gammopathy of undetermined significance, part of the multiple myeloma disease spectrum. She was referred to a retinal specialist for initiation of intravitreal injections of anti-vascular endothelial growth factor. Multiple myeloma has been implicated in younger patients as an underlying cause of retinal vein occlusions. Multiple myeloma should be considered as a differential diagnosis in young patients with retinal vein occlusions, even if other risk factors for venous occlusion like hypertension, diabetes mellitus and hypercholesterolaemia are present. Timely referral to the patient's primary care physician and haematologist is important for appropriate treatment and control of underlying systemic conditions. © 2015 Optometry Australia.

  2. 2D image compression using concurrent wavelet transform

    Science.gov (United States)

    Talukder, Kamrul Hasan; Harada, Koichi

    2011-10-01

    In the recent years wavelet transform (WT) has been widely used for image compression. As WT is a sequential process, much time is required to transform data. Here a new approach has been presented where the transformation process is executed concurrently. As a result the procedure runs first and the time of transformation is reduced. Multiple threads are used for row and column transformation and the communication among threads has been managed effectively. Thus, the transformation time has been reduced significantly. The proposed system provides better compression ratio and PSNR value with lower time complexity.

    This paper discusses knowledge sharing (inheritance) mechanisms for Object-Oriented Programming (OOP) in the context of concurrent (distributed) languages. We review three different schemes: inheritance, delegation and copy. A fourth model, called recipe-query, is presented and all are compared and criticized. Techniques relying on the shared memory assumption are rejected. We point out the conflict between distributing knowledge among objects and the synchronization of concurrent objects.

Our type system seems more natural and less restrictive than that originally presented by these authors for the concurrent case. Moreover, we show how to extend the language in order to formalise scheduling policies for systems of sequential thr...

  6. Applying Pareto multi-criteria decision making in concurrent engineering: A case study of polyethylene industry

    Full Text Available Concurrent engineering (CE is one of the widest known techniques for simultaneous planning of product and process design. In concurrent engineering, design processes are often complicated with multiple conflicting criteria and discrete sets of feasible alternatives. Thus multi-criteria decision making (MCDM techniques are integrated into CE to perform concurrent design. This paper proposes a design framework governed by MCDM technique, which are in conflict in the sense of competing for common resources to achieve variously different performance objectives such as financial, functional, environmental, etc. The Pareto MCDM model is applied to polyethylene pipe concurrent design governed by four criteria to determine the best alternative design to Pareto-compromise design.

    Full Text Available Background. Isolated tricuspid valve endocarditis in the absence of risk factors in the community setting is very rare and can be easily missed in patients with hitherto normal valves. Case Presentation. We present a case of a 49 year old gentleman who presented with generalized body aches, fever, and jaundice and was initial diagnosed as hepatitis. He subsequently developed recurrent episodes of panic attacks and shortness of breath and later multiple skin abscesses. Further investigations excluded pulmonary embolism but revealed multiple abscesses in the body including the lungs. Blood cultures and culture from abscesses grew S. aureus. An initial transthoracic echocardiogram was normal. A transesophageal echocardiogram subsequently confirmed endocarditis on a normal natural tricuspid valve and multiple lung abscesses. He was successfully treated with appropriate antibiotics. Conclusion. We discuss the pathogenesis of this patient's presentation highlight the need for assessment and proper evaluation of patients with unexplained bacteremia.

  8. Multiple Congenital Epulis in Alveolar Ridges of Maxilla and Mandible in a Newborn: A Rare Case Report

    Full Text Available Congenital granular cell lesion (CGCL or congenital epulis is an uncommon benign of the oral cavity tumor appearing at birth with typical clinical and pathologic features. It predominately affects females, mainly on the anterior maxillary alveolar ridge, and occurs usually as a single mass, although sometimes as multiple. The left side incisor area is the most common site. The etiology and histogenesis of the lesion remain obscure. Though it is a benign lesion, the tumor may cause feeding and respiratory problems if there are too large or multiple tumors. We report a case of a three-day-old, female newborn, who was referred to our hospital with multiple congenital oral swellings arising from the maxilla and mandible. The tumors caused a feeding problem and, hence, they were resected by surgical excision under general anesthesia.

  9. Non-syndromic multiple odontogenic keratocysts associated with dental anomalies: A report of unusual case and its management

    2015-01-01

    Full Text Available Odontogenic keratocyst (OKC, now known as keratocystic odontogenic tumor (KCOT, is the most common cystic lesion occurring in the maxillofacial region. Multiple occurrence of these cysts is less frequent and is usually associated with syndromes, the most common being the Gorlin Goltz syndrome or the nevoid basal cell carcinoma syndrome (NBCCS. We hereby report an unusual case of multiple OKCs in a healthy adult, associated with other dental anomalies. Management approach consisted of enucleation with curettage of the smaller lesions and decortication of buccal cortex in the large lesion. The condition in the present case may be because of the multifocal nature of OKC rather than its association with any syndrome. Concomitant occurrence of multiple OKCs with other dental anomalies may be coincidental. Impacted teeth or missing teeth must be radiographed to rule out the lesions associated with them.

    There is increasing concern about the possible long-term effects of multiple concussions, particularly on the developing adolescent brain. Whether the effect of multiple concussions is detectable in high school football players has not been well studied, although the public health implications are great in this population. To determine if there are measureable differences in cognitive functioning or symptom reporting in high school football players with a history of multiple concussions. Cross-sectional study; Level of evidence, 3. Participants included 5232 male adolescent football players (mean [±SD] age, 15.5 ± 1.2 years) who completed baseline testing between 2009 and 2014. On the basis of injury history, athletes were grouped into 0 (n = 4183), 1 (n = 733), 2 (n = 216), 3 (n = 67), or ≥4 (n = 33) prior concussions. Cognitive functioning was measured by the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery, and symptom ratings were obtained from the Post-Concussion Symptom Scale. There were no statistically significant differences between groups (based on the number of reported concussions) regarding cognitive functioning. Athletes with ≥3 prior concussions reported more symptoms than did athletes with 0 or 1 prior injury. In multivariate analyses, concussion history was independently related to symptom reporting but less so than developmental problems (eg, attention or learning problems) or other health problems (eg, past treatment for psychiatric problems, headaches, or migraines). In the largest study to date, high school football players with multiple past concussions performed the same on cognitive testing as those with no prior concussions. Concussion history was one of several factors that were independently related to symptom reporting. © 2016 The Author(s).

    2007-03-01

    An extensive large bowel resection with a single anastomosis is the accustomed management option for widely spaced synchronous colorectal neoplasms. We report a successful case of concurrent laparoscopic right hemicolectomy and ultra-low anterior resection with colonic J-pouch anal anastomosis in an 85-year-old man with synchronous cancers of the hepatic flexure and lowrectum. This surgical technique is advantageous for elderly patients as it provides the benefits of multiple segmental resection and laparoscopic surgery while potentially reducing mortality, time of procedure, postoperative pain, ileus, length of hospitalization and direct cost of care, and improving independence at discharge. The technique for efficient multiple extractions of specimens and effective reconstitution of pneumoperitoneum for a multistaged procedure is discussed.

    2015-04-15

    A 52-year-old woman visited our institution with upper abdominal pain which had lasted for the past two days. Laboratory tests revealed mild leukocytosis, decreased serum hemoglobin, and peripheral blood eosinophilia. CT scans showed multiple ill-defined, hypodense lesions in the peripheral areas of both hepatic lobes and active bleeding with a subcapsular hematoma in the right hepatic lobe. Angiography also showed active bleeding in the right hepatic lobe with multiple aneurysms, so a transarterial coil embolization was performed to stop the bleeding. The endoscopic retrograde cholangiopancreatography revealed several moving flat flukes in the common bile duct, which were pathologically confirmed as Fasciola hepatica.

    1995-03-01

    The case of a young man with the dual diagnoses of severe intellectual handicap (IQ 30 and mental age 4 years) and Multiple Personality Disorder is presented. The intellectual handicap is probably due to hypoxia in infancy and the Multiple Personality Disorder follows prolonged physical and sexual abuse. The patient frequently switches between any of nine discrete but incompletely formed identities. Although some personalities seem more capable than others, all have similar levels of disability on testing. The diagnosis of psychiatric disorders coexistent with the intellectual handicap is hindered by the difficulty in separating psychiatric phenomena from the behavioural disturbances associated with the disability. Differential diagnosis and management are discussed.

    2011-01-01

    As aerospace missions grow larger and more technically complex in the face of ever tighter budgets, it will become increasingly important to use concurrent engineering methods in the development of early conceptual designs because of their ability to facilitate rapid assessments and trades in a cost-efficient manner. To successfully accomplish these complex missions with limited funding, it is also essential to effectively leverage the strengths of individuals and teams across government, industry, academia, and international agencies by increased cooperation between organizations. As a result, the existing concurrent engineering teams will need to increasingly engage in distributed collaborative concurrent design. This paper is an extension of a recent white paper written by the Concurrent Engineering Working Group, which details the unique challenges of distributed collaborative concurrent engineering. This paper includes a short history of aerospace concurrent engineering, and defines the terms 'concurrent', 'collaborative' and 'distributed' in the context of aerospace concurrent engineering. In addition, a model for the levels of complexity of concurrent engineering teams is presented to provide a way to conceptualize information and data flow within these types of teams.

    Pyogenic tonsillitis may often be observed in the general Western population. In severe cases, it may require antibiotic treatment or even hospitalization and often a prompt clinical response will be noted. Here we present an unusual case of progressive multiple organ failure including fulminant liver failure following acute tonsillitis initially mistaken for "classic" pyogenic (that is bacterial) tonsillitis. A 68-year-old previously healthy white man was referred with suspicion of pyogenic angina. After tonsillectomy, he developed acute liver failure and consecutive multiple organ failure including acute hemodynamic, pulmonary and dialysis-dependent renal failure. Immunohistopathological analysis of his tonsils and liver as well as serum polymerase chain reaction analyses revealed herpes simplex virus-2 to be the causative pathogen. Treatment included high-dose acyclovir and multiorgan supportive intensive care therapy. His final outcome was favorable. Fulminant herpes simplex virus-2-induced multiple organ failure is rarely observed in the Western hemisphere and should be considered a potential diagnosis in patients with tonsillitis and multiple organ failure including acute liver failure. From a clinical perspective, it seems important to note that fulminant herpes simplex virus-2 infection may masquerade as "routine" bacterial severe sepsis/septic shock. This persevering condition should be diagnosed early and treated goal-oriented in order to gain control of this life-threatening condition.

    Full Text Available Cigarette smokers are being encouraged to use smokeless tobacco (SLT in locations where smoking is banned. We examined state-wide data from Minnesota to measure changes over time in the use of SLT and concurrent use of cigarettes and SLT. The Minnesota Adult Tobacco Survey was conducted four times between 1999 and 2010 and has provided state-wide estimates of cigarette smoking, SLT use and concurrent use of SLT by smokers. The prevalence of SLT was essentially unchanged through 2007, then increased significantly between 2007 and 2010 (3.1% versus 4.3%, P<0.05. Similarly, the prevalence of cigarette smokers who reported using SLT was stable then increased between 2007 and 2010 (4.4% versus 9.6%, P<0.05. The finding of higher SLT use by smokers could indicate that smokers in Minnesota are in an experimental phase of testing alternative products as they adjust to recent public policies restricting smoking in public places. The findings are suggestive that some Minnesota smokers are switching to concurrent use of cigarettes and SLT. Future surveillance reports will be necessary to confirm the results.

    2011-01-01

    The epidemiology of listeriosis in England and Wales changed during 2001-2008; more patients ≥60 years of age had bacteremia than in previous years. To investigate these changes, we calculated risk for listeriosis by concurrent condition for non-pregnancy-associated listeriosis cases reported to the national surveillance system in England during 1999-2009. Conditions occurring with L. monocytogenes infection were coded according to the International Classification of Diseases, 10th Revision, and compared with appropriate hospital episode statistics inpatient denominator data to calculate incidence rates/million consultations. Malignancies (especially of the blood), kidney disease, liver disease, diabetes, alcoholism, and age ≥60 years were associated with an increased risk for listeriosis. Physicians should consider a diagnosis of listeriosis when treating patients who have concurrent conditions. Providing cancer patients, who accounted for one third of cases, with food safety information might help limit additional cases.

    2017-01-01

    Objectives The objective of this study was to describe factors that influence the ability of state Medicaid agencies to report the Centers for Medicare & Medicaid Services' (CMS) core set of children's health care quality measures (Child Core Set). Methods We conducted a multiple-case study of four high-performing states participating in the Children's Health Insurance Program Reauthorization Act (CHIPRA) Quality Demonstration Grant Program: Illinois, Maine, Pennsylvania, and Oregon. Cases were purposively selected for their diverse measurement approaches and used data from 2010 to 2015, including 154 interviews, semiannual grant progress reports, and annual public reports on Child Core Set measures. We followed Yin's multiple-case study methodology to describe how and why each state increased the number of measures reported to CMS. Results All four states increased the number of Child Core Set measures reported to CMS during the grant period. Each took a different approach to reporting, depending on the available technical, organizational, and behavioral inputs in the state. Reporting capacity was influenced by a state's Medicaid data availability, ability to link to other state data systems, past experience with quality measurement, staff time and technical expertise, and demand for the measures. These factors were enhanced by CHIPRA Quality Demonstration grant funding and other federal capacity building activities, as hypothesized in our conceptual framework. These and other states have made progress reporting the Child Core Set since 2010. Conclusion With financial support and investment in state data systems and organizational factors, states can overcome challenges to reporting most of the Child Core Set measures.

    2015-12-01

    Malignant pleural mesothelioma (MPM) is the aggressive disease typically spreading along the pleural surface and encasing the lung, leading to respiratory failure or cachexia. Rare cases with atypical clinical manifestation or presentation have been reported in MPM. We experienced a unique case of MPM concurrently associated with miliary pulmonary metastases and nephrotic syndrome. A 73-year-old Japanese man with past history of asbestos exposure was referred to our hospital for the investigation of the left pleural effusion. Chest computed tomography showed thickening of the left parietal pleura. Biopsy specimen of the pleura showed proliferating epithelioid tumor cells, leading to the pathological diagnosis of epithelioid MPM with the aid of immunohistochemistry. After the diagnosis of MPM, chemotherapy was performed without effect. Soon after the clinical diagnosis of progressive disease with skull metastasis, edema and weight gain appeared. Laboratory data met the criteria of nephrotic syndrome, and renal biopsy with electron microscopic examination revealed the minimal change disease. Steroid therapy was started but showed no effect. Around the same time of onset of nephrotic syndrome, multiple miliary lung nodules appeared on chest CT. Transbronchial biopsy specimen of the nodules showed the metastatic MPM in the lung. The patient died because of the worsening of the general condition. To our knowledge, this is the first case of MPM concurrently associated with multiple miliary pulmonary metastases and nephrotic syndrome.

    Multiple endocrine tumors (MET) were observed in 27 of 4,136 autopsy cases (0.3%) of the fixed population including Hiroshima atomic bomb survivors and the control group. The thyroid was the most common organ in which MET occurred, followed by the ovary. Thirteen cases, including two cases of three MET, had MET in both the tyroid and the ovary, 11 of which had been exposed to one rad or more of atomic bomb.
