  1. Periodic active case finding for TB: when to look?

    Directory of Open Access Journals (Sweden)

    Peter J Dodd

    Full Text Available OBJECTIVE: To investigate the factors influencing the performance and cost-efficacy of periodic rounds of active case finding (ACF for TB. METHODS: A mathematical model of TB dynamics and periodic ACF (PACF in the HIV era, simplified by assuming constant prevalence of latent TB infection, is analyzed for features that control intervention outcome, measured as cases averted and cases found. Explanatory variables include baseline TB incidence, interval between PACF rounds, and different routine and PACF case-detection rates among HIV-infected and uninfected TB cases. FINDINGS: PACF can be cost-saving over a 10 year time frame if the cost-per-round is lower than a threshold proportional to initial incidence and cost-per-case-treated. More cases are averted at higher baseline incidence rates, when more potent PACF strategies are used, intervals between PACF rounds are shorter, and when the ratio of HIV-negative to positive TB cases detected is higher. More costly approaches, e.g. radiographic screening, can be as cost-effective as less costly alternatives if PACF case-detection is higher and/or implementation less frequent. CONCLUSION: Periodic ACF can both improve control and save medium-term health care costs in high TB burden settings. Greater costs of highly effective PACF at frequent (e.g. yearly intervals may be offset by higher numbers of cases averted in populations with high baseline TB incidence, higher prevalence of HIV-uninfected cases, higher costs per-case-treated, and more effective routine case-detection. Less intensive approaches may still be cost-neutral or cost-saving in populations lacking one or more of these key determinants.

    Tuberculosis control depends on successful case finding and treatment of individuals infected with Mycobacterium tuberculosis. Passive case finding is widely practised: the present study aims to ascertain the consensus and possible improvements in active case finding across Europe. Recommendations...... from national guidelines were collected from 50 countries of the World Health Organization European region using a standard questionnaire. Contacts are universally screened for active tuberculosis and latent tuberculosis infection (LTBI). Most countries (>70%) screen those with HIV infection, prisoners...... and in-patient contacts. Screening of immigrants is related to their contribution to national rates of tuberculosis. Only 25 (50%) out of 50 advise a request for symptoms in their guidelines. A total of 36 (72%) out of 50 countries recommend sputum examination for those with a persistent cough; 13...

    Full Text Available Hansen's disease (leprosy remains an important health problem in Brazil, where 34,894 new cases were diagnosed in 2010, corresponding to 15.3% of the world's new cases detected in that year. The purpose of this study was to use home visits as a tool for surveillance of Hansen's disease in a hyperendemic area in Brazil. A total of 258 residences were visited with 719 individuals examined. Of these, 82 individuals had had a previous history of Hansen's disease, 209 were their household contacts and 428 lived in neighboring residences. Fifteen new Hansen's disease cases were confirmed, yielding a detection rate of 2.0% of people examined. There was no difference in the detection rate between household and neighbor contacts (p = 0.615. The two groups had the same background in relation to education (p = 0.510, household income (p = 0.582, and the number of people living in the residence (p = 0.188. Spatial analysis showed clustering of newly diagnosed cases and association with residential coordinates of previously diagnosed multibacillary cases. Active case finding is an important tool for Hansen's disease control in hyperendemic areas, enabling earlier diagnosis, treatment, decrease in disability from Hansen's disease and potentially less spread of Mycobacterium leprae.

    Full Text Available BACKGROUND: The potential population-level impact of private-sector initiatives for tuberculosis (TB case finding in Southeast Asia remains uncertain. In 2011, the Indus Hospital TB Control Program in Karachi, Pakistan, undertook an aggressive case-finding campaign that doubled notification rates, providing an opportunity to investigate potential population-level effects. METHODS: We constructed an age-structured compartmental model of TB in the intervention area. We fit the model using field and literature data, assuming that TB incidence equaled the estimated nationwide incidence in Pakistan (primary analysis, or 1.5 times greater (high-incidence scenario. We modeled the intervention as an increase in the rate of formal-sector TB diagnosis and evaluated the potential impact of sustaining this rate for five years. RESULTS: In the primary analysis, the five-year intervention averted 24% (95% uncertainty range, UR: 18-30% of five-year cumulative TB cases and 52% (95% UR: 45-57% of cumulative TB deaths. Corresponding reductions in the high-incidence scenario were 12% (95% UR: 8-17% and 27% (95% UR: 21-34%, although the absolute number of lives saved was higher. At the end of five years, TB notification rates in the primary analysis were below their 2010 baseline, incidence had dropped by 45%, and annual mortality had fallen by 72%. About half of the cumulative impact on incidence and mortality could be achieved with a one-year intervention. CONCLUSIONS: Sustained, multifaceted, and innovative approaches to TB case-finding in Asian megacities can have substantial community-wide epidemiological impact.

    Background. Haiti has the highest tuberculosis (TB) prevalence in the Americas with 254 cases per 100,000 persons. Case detection relies on passive detection and TB services in many regions suffer from poor diagnostic and clinical resources. Methods. Mache Chache ("Go and Seek") was a TB REACH Wave 3 funded TB case finding project in Port-au-Prince between July 2013 and September 2014, targeting four intervention areas with insufficient TB diagnostic performance. Results. Based on a verbal symptom screen emphasizing the presence of cough, the project identified 11,150 (11.75%) of all screened persons as TB subjects and 2.67% as smear-positive (SS+) TB cases. Enhanced case finding and strengthening of laboratory services led to a 59% increase in bacteriologically confirmed cases in the evaluation population. In addition, smear grades dropped significantly, suggesting earlier case detection. Xpert® MTB/RIF was successfully introduced and improved TB diagnosis in HIV-infected, smear-negative clinic patients, but not in HIV-negative, smear-negative TB suspects in the community. However, the number needed to screen for one additional SS+ case varied widely between clinic and community screening activities. Conclusion. Enhanced and active TB case finding in Haiti can improve TB diagnosis and care. However, screening algorithms have to be tailored to individual settings, necessitating long-term commitment.

    Anna H Van't Hoog

    Full Text Available BACKGROUND: The findings of a prevalence survey conducted in western Kenya, in a population with 14.9% HIV prevalence suggested inadequate case finding. We found a high burden of infectious and largely undiagnosed pulmonary tuberculosis (PTB, that a quarter of the prevalent cases had not yet sought care, and a low case detection rate. OBJECTIVE AND METHODS: We aimed to identify factors associated with inadequate case finding among adults with PTB in this population by comparing characteristics of 194 PTB patients diagnosed in a health facility after self-report, i.e., through passive case detection, with 88 patients identified through active case detection during the prevalence survey. We examined associations between method of case detection and patient characteristics, including HIV-status, socio-demographic variables and disease severity in univariable and multivariable logistic regression analyses. FINDINGS: HIV-infection was associated with faster passive case detection in univariable analysis (crude OR 3.5, 95% confidence interval (CI 2.0-5.9, but in multivariable logistic regression this was largely explained by the presence of cough, illness and clinically diagnosed smear-negative TB (adjusted OR (aOR HIV 1.8, 95% CI 0.85-3.7. Among the HIV-uninfected passive case detection was less successful in older patients aOR 0.76, 95%CI 0.60-0.97 per 10 years increase, and women (aOR 0.27, 95%CI 0.10-0.73. Reported current or past alcohol use reduced passive case detection in both groups (0.42, 95% CI 0.23-0.79. Among smear-positive patients median durations of cough were 4.0 and 6.9 months in HIV-infected and uninfected patients, respectively. CONCLUSION: HIV-uninfected patients with infectious TB who were older, female, relatively less ill, or had a cough of a shorter duration were less likely found through passive case detection. In addition to intensified case finding in HIV-infected persons, increasing the suspicion of TB among HIV

    Sayera Banu

    Full Text Available Understanding tuberculosis (TB transmission dynamics is essential for establishing effective TB control strategies in settings where the burden and risk of transmission are high. The objectives of this study were to evaluate the effect of active screening on controlling TB transmission and also to characterize Mycobacterium tuberculosis strains for investigating transmission dynamics in a correctional setting.The study was carried out in Dhaka Central Jail (DCJ, from October 2005 to February 2010. An active case finding strategy for pulmonary TB was established both at the entry point to the prison and inside the prison. Three sputum specimens were collected from all pulmonary TB suspects and subjected to smear microscopy, culture, and drug susceptibility testing as well as genotyping which included deletion analysis, spoligotyping and analysis of mycobacterial interspersed repetitive units (MIRU.A total of 60,585 inmates were screened during the study period. We found 466 inmates with pulmonary TB of whom 357 (77% had positive smear microscopy results and 109 (23% had negative smear microscopy results but had positive results on culture. The number of pulmonary TB cases declined significantly, from 49 cases during the first quarter to 8 cases in the final quarter of the study period (p=0.001. Deletion analysis identified all isolates as M. tuberculosis and further identified 229 (70% strains as 'modern' and 100 (30% strains as 'ancestral'. Analysis of MIRU showed that 347 strains (85% exhibited unique patterns, whereas 61 strains (15% clustered into 22 groups. The largest cluster comprised eight strains of the Beijing M. tuberculosis type. The rate of recent transmission was estimated to be 9.6%.Implementation of active screening for TB was associated with a decline in TB cases in DCJ. Implementation of active screening in prison settings might substantially reduce the national burden of TB in Bangladesh.

    Natalie Lorent

    Full Text Available In light of the limitations of the current case finding strategies and the global urgency to improve tuberculosis (TB case-detection, a renewed interest in active case finding (ACF has risen. The WHO calls for more evidence on innovative ways of TB screening, especially from low-income countries, to inform global guideline development. We aimed to assess the feasibility of community-based ACF for TB among the urban poor in Cambodia and determine its impact on case detection, treatment uptake and outcome.Between 9/2/2012-31/3/2013 the Sihanouk Hospital Center of HOPE conducted a door-to-door survey for TB in deprived communities of Phnom Penh. TB workers and community health volunteers performed symptom screening, collected sputum and facilitated specimen transport to the laboratories. Fluorescence microscopy was introduced at three referral hospitals. The GeneXpert MTB/RIF assay (Xpert was performed at tertiary level for individuals at increased risk of HIV-associated, drug-resistant or smear-negative TB. Mobile phone/short message system (SMS was used for same-day issuing of positive results. TB workers contacted diagnosed patients and referred them for care at their local health centre.In 14 months, we screened 315.874 individuals; we identified 12.201 aged ≥ 15 years with symptoms suggestive of TB; 84% provided sputum. We diagnosed 783, including 737 bacteriologically confirmed, TB cases. Xpert testing yielded 41% and 48% additional diagnoses among presumptive HIV-associated and multidrug-resistant TB cases, respectively. The median time from sputum collection to notification (by SMS of the first positive (microscopy or Xpert result was 3 days (IQR 2-6. Over 94% commenced TB treatment and 81% successfully completed it.Our findings suggest that among the urban poor ACF for TB, using a sensitive symptom screen followed by smear-microscopy and targeted Xpert, contributed to improved case detection of drug-susceptible and drug-resistant TB

    Wheeler, Christopher

    This study focused on how physics teachers develop and implement activities that promote creative thinking strategies in the standards based physics classroom. A particular focus was placed on every day or little "c", creativity, which can be taught in the high school classroom. The study utilized a multiple case study design, which allows for in-depth study in a variety of settings. Four participants from various high schools were identified utilizing administrator recommendations. Data were then collected via interviews, observations, and documents. The data were coded and analyzed for emerging themes. The themes were then merged to determine findings to the stated research questions. The research demonstrated the importance of modifying activities for student interest and understanding through effective use of scientific inquiry. The past experiences and professional development of the participants served as a vital piece to the development of their educational pedagogy especially concerning inquiry and questioning strategies. It was also established that an unstructured, positive classroom environment is a vital aspect of teaching while supporting creative thinking skills.

    Full Text Available BACKGROUND: The World Health Organization is currently developing guidelines on screening for tuberculosis disease to inform national screening strategies. This process is complicated by significant gaps in knowledge regarding mass screening. This study aimed to assess feasibility, uptake, yield, treatment outcomes, and costs of adding an active tuberculosis case-finding program to an existing mobile HIV testing service. METHODS AND FINDINGS: The study was conducted at a mobile HIV testing service operating in deprived communities in Cape Town, South Africa. All HIV-negative individuals with symptoms suggestive of tuberculosis, and all HIV-positive individuals regardless of symptoms were eligible for participation and referred for sputum induction. Samples were examined by microscopy and culture. Active tuberculosis case finding was conducted on 181 days at 58 different sites. Of the 6,309 adults who accessed the mobile clinic, 1,385 were eligible and 1,130 (81.6% were enrolled. The prevalence of smear-positive tuberculosis was 2.2% (95% CI 1.1-4.0, 3.3% (95% CI 1.4-6.4, and 0.4% (95% CI 1.4 015-6.4 in HIV-negative individuals, individuals newly diagnosed with HIV, and known HIV, respectively. The corresponding prevalence of culture-positive tuberculosis was 5.3% (95% CI 3.5-7.7, 7.4% (95% CI 4.5-11.5, 4.3% (95% CI 2.3-7.4, respectively. Of the 56 new tuberculosis cases detected, 42 started tuberculosis treatment and 34 (81.0% completed treatment. The cost of the intervention was US$1,117 per tuberculosis case detected and US$2,458 per tuberculosis case cured. The generalisability of the study is limited to similar settings with comparable levels of deprivation and TB and HIV prevalence. CONCLUSIONS: Mobile active tuberculosis case finding in deprived populations with a high burden of HIV and tuberculosis is feasible, has a high uptake, yield, and treatment success. Further work is now required to examine cost-effectiveness and affordability and

    Contexte : Vingt-deux districts du Népal où des activités intensifiées de recherche des cas (ICF) de la tuberculose (TB) ont été mises en œuvre au sein de groupes à risque sous l'égide du projet TB REACH en collaboration avec le programme national TB entre juillet 2013 et novembre 2015.Objectifs : Evaluer le rendement du dépistage de la TB grâce à un algorithme basé sur la microscopie de frottis suivie d'un test Xpert(®) MTB/RIF.Schéma : Etude descriptive basée sur des données recueillies en routine.Résultats : Sur un total de 145 679 individus dépistés, 28 574 (19,6%) ont été présumés atteints de TB ; 1239 (4,3%) d'entre eux ont eu une confirmation du diagnostic de TB ; parmi ces derniers, 1195 (96%) ont mis en route un traitement anti-tuberculose. Le rendement a été le plus élevé parmi les personnes vivant avec le virus l'immunodéficience humaine (PVVIH) (6,1%) suivies par les contacts domiciliaires (3,5%) et les habitants des bidonvilles (0,5%). Dans d'autres groupes à risque comme les prisonniers, les travailleurs d'usine, les réfugiés et les diabétiques, le rendement a été inférieur à 0,5%. Le nombre de personnes à dépister (NNS) pour diagnostiquer un cas de TB active a été de 17 pour les PVVIH, de 29 pour les contacts domiciliaires et de 197 pour les habitants des bidonvilles urbains. Sur 11 525 patients émanant soit du programme ICF soit du dépistage de routine, 112 (1%) ont eu un diagnostic de TB multirésistante.Conclusion : Le rendement en termes de cas de TB dépistés parmi les groupes à risque comme les PVVIH et les contacts domiciliaires a été substantiel. Même si ce rendement a été modeste parmi les habitants des bidonvilles, ceux-ci justifient néanmoins une intervention en raison de leur nombre élevé et de leur médiocre accès aux soins.

    Six hundred and ninety nine cases of alleged rape were studied by the authors during the period from 2007-2008 at the Mymensingh Medical College, Mymensingh. Of these cases, 122 had positive findings of recent sexual intercourse; 250 cases had the positive findings of habituated sexual intercourse, and 327 cases had no findings of sexual intercourse but they complained of forcible sexual intercourse and found no sign of sexual intercourse. Most of the alleged victims of rape were nulliparous 87.12% and parous was only 12.87%. 430 (61.51%) cases of reported victims who were students of schools and colleges were not considered as rape cases considering their victim's history of love affairs, leaving home secretly with their lovers, living with them for many days. Gang rape was not so common (4.29% of raped cases) in our study. Age groups, their occupations, living areas, time of arrival for medico-legal examination have been studied. Most of the cases were students (61.51%). A few numbers of victims were subjected to gang rape. Examination and reporting the cases have been discussed.

    Full Text Available Malaria is an infectious disease caused by protozoa of the genus Plasmodium. Cutaneous lesions in malaria are rarely reported and include urticaria, angioedema, petechiae, purpura, and disseminated intravascular coagulation (DIC. Here, five malaria cases associated with cutaneous lesions have been described. Out of the five cases of malaria, two were associated with urticaria and angioedema, one case was associated with urticaria, and other two were associated with reticulated blotchy erythema with petechiae. Most of the cutaneous lesions in malaria were nonspecific and reflected the different immunopathological mechanism in malarial infection.

    Full Text Available Histiocytic sarcoma (HS is a neoplasm derived from histiocytes. Its diagnosis was not clear until its immunohistochemistry profile was correctly established. Not much is known about its genetic properties. We report a case of a 48-year-old male patient whose bone marrow was almost completely occupied by monomorphic medium size neoplastic cellularity. Its immunohistochemical profile was CD68+, CD4+, CD45+ with negativity of other dendritic cells, and other lineage markers. Cytogenetic study showed 4 related clones: one with trisomy 8 and extra material on the short arms of chromosome 4; a second line with tetrasomy of chromosome 8, add(4(p16; the third clone had the same alterations as the previous and deletion of chromosome 3 at q11; the fourth line had tetrasomy 8 and translocation t(3;5(q25;q35. To our knowledge this is the first HS case showing chromosome 8 trisomy and tetrasomy and the other described alterations.

  17. Finding Community Structures In Social Activity Data

    2015-05-19

    Social activity data sets are increasing in number and volume. Finding community structure in such data is valuable in many applications. For example, understand- ing the community structure of social networks may reduce the spread of epidemics or boost advertising revenue; discovering partitions in tra c networks can help to optimize routing and to reduce congestion; finding a group of users with common interests can allow a system to recommend useful items. Among many aspects, qual- ity of inference and e ciency in finding community structures in such data sets are of paramount concern. In this thesis, we propose several approaches to improve com- munity detection in these aspects. The first approach utilizes the concept of K-cores to reduce the size of the problem. The K-core of a graph is the largest subgraph within which each node has at least K connections. We propose a framework that accelerates community detection. It first applies a traditional algorithm that is relatively slow to the K-core, and then uses a fast heuristic to infer community labels for the remaining nodes. The second approach is to scale the algorithm to multi-processor systems. We de- vise a scalable community detection algorithm for large networks based on stochastic block models. It is an alternating iterative algorithm using a maximum likelihood ap- proach. Compared with traditional inference algorithms for stochastic block models, our algorithm can scale to large networks and run on multi-processor systems. The time complexity is linear in the number of edges of the input network. The third approach is to improve the quality. We propose a framework for non- negative matrix factorization that allows the imposition of linear or approximately linear constraints on each factor. An example of the applications is to find community structures in bipartite networks, which is useful in recommender systems. Our algorithms are compared with the results in recent papers and their quality and e

    Full Text Available Abstract Background This case report describes the clinical and ultrasonographic findings in a Swiss Braunvieh cow with lymphosarcoma of the abomasum. Case Presentation The main clinical findings were vomiting in response to eating and melena. The results of serum biochemistry and rumen fluid analysis were indicative of abomasal reflux syndrome. The main ultrasonographic findings were two enlarged lymph nodes caudal to the reticulum and a severely enlarged abomasum with thickening of the abomasal wall and folds. Based on all the findings, pyloric stenosis caused by lymphosarcoma was tentatively diagnosed and later confirmed at postmortem examination. Conclusions This is an interesting case, which broadens the spectrum of abomasal reflux syndrome.

    International Nuclear Information System (INIS)

    Ehrlichiosis is a rare disease, with approximately 400 cases having been documented in the US since its recognition in 1986. Most of the reported cases were in the southeastern US, although 6 cases have been described in Washington state. Although most of these reported patients were admitted to hospital, severe complications developed in only a small proportion. Findings on chest imaging have been described in 3 children. To our knowledge, this is the first reported case of computed tomographic (CT) findings in a young adult with erhlichiosis in whom acute respiratory failure developed. (author)

  2. s-Findings of active pulmonary tuberculosis in computed tomography

    International Nuclear Information System (INIS)

    Purpose: Tuberculosis remains the most important infectious disease all over the world. We report on the CT findings of lung tuberculosis. Material and methods: Standardised retrospective analysis of the computed tomographic examinations in a total of 100 patients suffering from cultural or histological proven pulmonary tuberculosis. Results: The most common finding in our study group were micronodules and lobular opacities accompanied by enlarged lymph nodes. Cavitation and alteration of the bronchial system (esp. bronchial wall thickening) were found less common. The so-called tree- in bud-appearance which had been estimated by other authors to be rather characteristic for active pulmonary tuberculosis was seen in only 12/100 examinations. It is often found in cases showing severe bronchogenic spreading of the disease. Conclusion: The active pulmonary tuberculosis does not show any pathognomonic sign but the combination of findings as opacities and cavitation and segmental spreaded micronodules make the diagnosis probable. This holds also for the so-called tree- in-bud appearances which may be rather suggestive but is seen only in cases suffering from severe bronchiogenic propagation. (orig.)

    Full Text Available The key informant methodology for case finding for childhood cataract  was utilized  in a rural population in Nigeria to identify suitable children who would benefit surgically from intervene for cataract and restore vision such children. It was however noticed that some parents who had children with cataract did not bring their children to the primary health center for examination and recommendation. The purpose of this study is to investigate the benefits of using the theatre for development approach in childhood cataract case finding. The delay in identification and referral of children with cataract at an appropriate age for surgical intervention and optical rehabilitation is the main cause of poor vision following surgery for the condition as amblyopia results. Therefore early presentation, identification, referral and surgical intervention as well as appropriate optical rehabilitation is the key to successful surgical outcome of childhood cataract and good visual prognosis. The theater for development (TfD approach methodology was implemented in a community in Akpabuyo local government are of Cross River state, Nigeria as a means to enhance community participation, health promotion and education and to complement the key informant methodology in case finding for childhood cataract. Three children with cataracts were referred by the community following the TfD intervention, for cataract surgery and uptake of follow up care after surgery. The TfD approach appears to be a useful method for encouraging community participation in the case finding of childhood cataract.

    Nail-patella syndrome is a rare autosomal dominant pleiotropic disorder characterized by dysplasia of the nails, pateller aplasia or hypoplasia, iliac horns, and dysplasia or dislocation of the elbow. We experienced a case of nail-patella syndrome. NPS is a relatively uncommon disease; however, an understanding of the typical radiologic findings is useful in establishing the diagnosis and guiding the treatment.

  6. Hydatid disease of the cranium: neuroradiological findings in one case

    International Nuclear Information System (INIS)

    Hydatid disease is caused by Echinococcus granulosus. The most common locations for hydatid cysts are lung and liver. The central nervous system is involved in only 2% of cases, and these cysts are usually located in the brain parenchyma. Primary involvement of the bones of the skull is very uncommon. We report the case of a child with cranial echinococcosis which presented in the form of an osteolytic lesion with an extradural cyst. This was the unique feature of the disease. The CT and MR findings are described. This presentation has rarely been reported in the literature. (Author) 5 refs

    Full Text Available Mucopolysaccharidosis VI or Maroteaux-Lamy syndrome is an autosomal recessive lysosomal storage disorder with multisystem involvement which is determined by mutations in the arylsulfatase B (ARSB gene. Herein, we report the radiological findings of a case of Mucopolysaccharidosis VI which showed progression of periventricular lesions on follow-up magnetic resonance imaging (MRI and slight elevation of myoinositole and no other significant pathological peak on magnetic resonance (MR spectroscopy. MR spectroscopy as well as the clinical findings helped us to exclude some of the diseases in the differential diagnosis.

    Full Text Available Medulloblastoma is a brain tumor of neuroepithelial origin, which represents 15 to 30% of all pediatric brain tumors, and less than 1% of CNS adult neoplasms. We report the imaging findings of 8 adult patients with medulloblastoma. The mean age was 35 years, ranging from 20 to 65 years, and the male:female rate was 3:5. The tumors were predominantly lateral (63%, hyperdense on CT scans (83%, and on the MRI, hypointense on T1 (100% and hyperintense on T2 (80% weighted images. It was seen intratumoral necrosis and cysts in six cases and calcifications in three. Hydrocephalus was observed in 5 cases and brain stem invasion in four. The imaging findings of medulloblastomas in adults are different of those in child, and also nonspecific. Although these tumors are uncommon in adults, they must be considered in the differential diagnosis of cerebellar masses in the posterior fossa of this age group.

  16. CT and MR findings of chordoid meningioma: a case report

    International Nuclear Information System (INIS)

    A 25-year-old woman with focal seizure, intermittent morning headache and vomiting for 2 years showed microcytic hypochromic anemia on peripheral blood smear and a 6 x 6 x 7.5 cm sized intracranial mass with cystic and solid portions at the right temporoparietal convexity on brain CT and MRI which was hypervascular on cerebral angiography. Histopathologic findings on light microscopy suggested chordoma, but it was confirmed as a chordoid meningioma by immunohistochemical study. The present case suggests that the diagnosis of chordoid meningioma should be considered in a juvenile or young adult who is presented with an extra-axial mass with typical location of meningiomas, findings of chordomas on light microscopy, and clinical findings of Castleman syndrome

    We wanted to describe the CT findings of small bowel anisakiasis with the pathologic correlation. Four patients with surgically and pathologically proven small bowel anisakiasis were included in this retrospective study. They were three men and one woman and their ages ranged from 28 to 43 years (mean age: 38 years). We evaluated their clinical, CT and histological findings. All the patients had a history of ingesting raw fish within 24 hours from the time of symptom onset. They complained of abdominal pain (n=4), nausea (n=4), vomiting (n=2) and diarrhea (n=1). Physical examination revealed tenderness (n=4), rebound tenderness (n=4) and increased bowel sounds (n=3). Leukocytosis was noted in all the patients on the laboratory examination. None of the patients showed eosinophilia. The CT findings were segmental small bowel wall thickening with preserved layering (n=4), focal segmental luminal narrowing with proximal dilatation (n=4), peritoneal thickening (n=3), mesenteric or omental infiltration (n=4) and varying degrees of ascites (n=4). On the histopathologic examination, they revealed an infiltration of eosinophils (n=4) in all layers of the bowel wall with severe edema. The larvae were found on surgico-pathologic examination in all the cases. The CT findings may be helpful to make the specific diagnosis of small bowel anisakiasis in a patient with the clinical findings of an acute abdomen and a history of eating raw fish

    CT scans of a 59-year-old woman, with serologically comfirmed herpes simplex encephalitis (HSE) were studied sequentially from 9 days after onset. The initial findings in CT scan were low density areas in insular cortex, claustrum and hippocampus. The low density areas, then, spread to the temporal lobe, rectal and cingulate gyri and occipital lobe, according to clinical progression of the disease. However, these low density areas disappeared and changed into isodensity areas in 25-35 days after oneset, which then returned to low density areas again in 51 days after onset. Thes characteristic phenomenon resembled a ''fogging effect,'' which is frequently seen during the second or third week after onset of ischemic cerebral infarction. HSE is characterized pathologically by acute hemorrhagic necrotizing encephalitis. Though cerebral angiography was not performed in this case, these characteristic CT findings suggested that HSE may have been associated with vascular involvement.

    Portal vein thrombosis secondary to protein C deficiency is a rare finding. Diagnosing a portal vein thrombosis itself is difficult due to nonspecific symptoms such as nausea, vomiting, anorexia, and weight loss. Proving that a protein C deficiency is the cause of a portal vein thrombosis is even more difficult as an extensive and thorough workup is required to rule out malignancies, myeloproliferative disorders, and hypercoaguable states which can all lead to thromboses. Patients require anticoagulation to prevent two dangerous complications of portal vein thrombosis; portal hypertension leading to esophageal varices with massive hemetemesis and extension of thrombus from the portal vein into the mesenteric veins leading to intestinal ischemia and death. In this case report, we present a patient with the complaint of painless jaundice who was found to have an incidental finding of portal vein thrombosis secondary to protein C deficiency. The different etiologies of portal vein thrombosis, along with diagnosis and treatment options will be discussed and highlighted. PMID:18410831

    Exogenous lipoid pneumonia is an unusual disease resulting from aspiration of oil particles. A history of oil ingestion strongly suggests the diagnosis, but the radiological presentation varies from mild perihilar consolidation to diffuse and extensive bilateral involvement, particularly of the posterior basal segment of both lower lung. Since magnetic resonance (MR) provides greater contrast resolution than CT, it offers the potential for tissue characterization. In particular, fatty tissue and lipid containing substances are known to have high signal intensities on T1-and T2-weighted spin-echo (SE) images. We report MR findings in two case of exogenous lipoid pneumonia caused by ingestion of shark liver oil (Squalene)

    Brucellosis is a systemic infectious disease, and musculoskeletal involvement is a frequent complication. Particularly, spondylitis is a common involvement. However, early diagnosis of brucellar spondylitis is often difficult due to non-specific clinical symptoms and long latent period. Especially in Korea, where tuberculosis is an endemic disease, differentiation between tuberculous and brucellar spondylitis is clinically and radiologically more challenging. A 59-year-old male cattle farmer, who presented with non-specific back pain, had spondylitis on magnetic resonance imaging (MRI), and serologic test finally confirmed brucellar spondylitis. Therefore, we report a case of a rather rare disease in Korea, brucellar spondylitis with a review of MRI findings.

    Pacinian neuroma is a rare tumor characterized by hypertrophy and hyperplasia of preexisting pacinian corpuscles. This tumor most frequently presents as a small superficial mass affecting the hands and feet, which produces localized sharp pain. The etiology is unknown, but local trauma has been postulated as an important factor. Here we report a case of posttraumatic pacinian neuroma in a 24-year-old woman who presented with severe local pain in the palm. The clinical features, and the sonographic and pathologic findings of posttraumatic pacinian neuroma are discussed

    Esophageal schwannomas are a relative rare benign neoplasm that usually occurs in the upper esophagus, in the middle aged women. We report a case of a 67-year-old man with a lower esophageal schwannoma. This lesion was composed of homogenous density, iso-attenuating with the chest wall muscle on pre- and post-contrast chest computed tomography (CT). The CT findings of the esophageal schwannoma are similar to those of esophageal leiomyoma. Hense, esophageal schwannoma may be a differential diagnosis with esophageal leiomyoma.

    Full Text Available Background and Design: Sweet syndrome is an inflammatory disease characterized by the abrupt onset of pain, red papules and plaques, fever, neutrophilic leukocytosis, and dermal neutrophilic infiltrate. There are not enough data about Sweet syndrome in Turkey. In this article, we studied clinical, laboratory, histopathological, and epidemiological characteristics of patients, who presented to our clinic, and compared the findings with the literature. Materials and Methods: All patients diagnosed with Sweet syndrome in our clinic between 2005 and 2011 were included in the study. The epidemiological, clinical, and laboratory findings were retrospectively evaluated. Results: A total of 31 patients with Sweet’s syndrome - 24 female (77.4%, 7 male (22.6%; aged 23-82 years – included in the study. The average age of the patients was 48 years. Cutaneous lesions were most frequently localized in the upper extremity. Conjunctivitis was the common systemic manifestation, followed by fever, arthralgia, and myalgia. The most common trigger factor was infections of the upper respiratory tract. In histopathological evaluations of skin biopsies, dense neutrophil infiltration compatible with Sweet syndrome was detected in the dermis. Also, findings of vasculitis were determined in 3 patients. Discussion: The clinical and laboratory findings in our study are mostly similar to those reported in the literature. We found evidence of vasculitis in 10% of cases, therefore, we think the presence of vasculitis does not necessarily rule out the diagnosis of Sweet syndrome

    Full Text Available OBJECTIVE To present the magnetic resonance imaging findings of 30 cases of intracranial meningiomas diagnosed in a single institute. Magnetic resonance imaging (MRI with contrast is the modality of choice for diagnosis of meningiomas. Objective of this study was to describe typical and atypical locations and findings of intracranial meningiomas on magnetic resonance imaging. MATERIALS AND METHODS This study was conducted at Department of Radiology, Government General Hospital, Kakinada from January 2013 to August 2014 over a period of 20 months. 30 patients of intracranial meningiomas of 15-75 years’ age group were studied. RESULTS A higher incidence noted in females. Most of the tumours are solitary. The most common sites of occurrence are the cerebral convexities, parasagittal location/falx, posterior fossa, sphenoid ridge, olfactory groove. Majority were typical (WHO grade 1 in 96.6%, only 3.4% were atypical (WHO grade 2. Most of the tumours showed low signal on T1- (60% and high signal on T2- (68% and FLAIR (69% weighted images. Also, the lesions showed heterogeneous signal on T1 (60%, T2 (68% and FLAIR (64% sequences. After contrast administration, 67% of the tumours presented intense and 33% showed moderate and heterogenous enhancement. The most common sites of occurrence are the cerebral convexities, parasagittal location/falx, posterior fossa, sphenoid ridge, olfactory groove and others accounting for 33.3%, 20%, 20%, 10%, 6.7%, 10% respectively. Areas of vasogenic oedema around the tumours were seen in 33% of the cases. Twenty percent of the cases showed bone infiltration, and the dural tail sign was seen in 56% of the tumours. CONCLUSION The diagnosis of meningioma is usually straightforward except when it presents in unusual locations and with atypical imaging characteristics. MRI is the modality of choice for diagnosis as well as for predicting the success of its complete removal.

    A 66-year-old female was admitted to our hospital with chief complaint of vertigo, gait disturbance and dysarthria. These symptoms started about one year before admission and worsened. Vomiting and urinary incontinence appeared. Neurological examination revealed left cerebellar ataxia and dysarthria. In plain CT (computerized tomography) irregular ill-defined low density area was noted in the cerebellar vermis and bilateral cerebellar hemispheres. And slight ventricular dilatation was found. Irregular shape of ring-like enhancement corresponding to capsule and patchy or mottled enhancement inside the tumor were seen. Suboccipital craniectomy was performed and yellowish necrotic tumor with hard capsule was removed. Histological diagnosis was not neoplasm or tuberculoma. Postoperatively liver function progressively worsened. She died due to disseminated intravascular coagulation. Autopsy revealed typical liver cirrhosis without malignant change. 3.0 x 2.5 cm sized, slightly hard, yellowish lesion was found on upper part of cerebellar hemispheres. This had extremely necrotic tissue and a great number of cryptococcus neoformans were found. And other intracranial lesion was not confirmed. Finding of pulmonary cryptococcosis was not gained. Our case is very rare because of solitary cerebellar abscess and absence of meningitic episode or pulmonary cryptococcosis. There are three types of inflammation in cerebral cryptococcosis. The commonest manifestation is the meningitic type, the second mode is granulomatous lesion and the third and the least presentation is intracranial abscess formation. CT reveals various finidngs according to clinical stage. CT findings are those of meningitis, meningoencephalitis, granuloma and abscess. Cryptococcal granuloma or abscess often simulates brain abscess, glioma and metastatic brain tumor. We discussed CT findings of cerebral cryptococcosis and examined the CT number of our case.

    Purpose: To retrospectively review magnetic resonance (MR) imaging features in a series of six infantile fibrosarcomas to find out if MR can suggest this unusual diagnosis and to highlight the value of MR during and following treatment. Materials and methods: The records of six cases of histologically proven infantile fibrosarcoma were retrieved from the files of our cancer center. All imaging data available were consensually reviewed by two radiologists. Results: There were five females and one male (age range at diagnosis, 0-12 months; mean, 6 months). The most common finding was a well-circumscribed single mass in five patients (83%). All tumors had arisen on limbs; at their proximal or distal extremity or at the root of the limb. The masses were 9 cm large in mean diameter. The initial tumor signal was isointense to muscle on T1-weighted and hyperintense on T2-weighted sequences. All masses were well circumscribed and half of them contained internal fibrous septa. The internal signal was homogeneous in three patients and heterogeneous in the three others. An intense enhancement was seen in all three contrast-enhanced exams available; heterogeneous in two cases and homogeneous in one. Osseous erosion was observed in only one patient who was the only one with distant metastasis. After treatment (chemotherapy and very limited surgery), tumors had totally disappeared, leaving muscle fat infiltration in two patients and subcutaneous fat hypertrophy in one patient. Conclusion: Although imaging findings are not specific of infantile fibrosarcoma, this diagnosis could be suggested when MR imaging depicts a large well-circumscribed mass arising in a limb at birth or during the neonatal period. This mass is sometimes heterogeneous and septate and exhibits an isointense T1- and hyperintense T2-weighted signals and strong enhancement. MR is also the technique of choice for follow-up during treatment which consists nowadays almost exclusively in chemotherapy.

    2013-01-01

    Full Text Available Background: Genital tuberculosis is a chorionic disease and mostly occurs by haematogenous spread from extra genital source like lungs, peritoneum, lymph nodes and bones. Transmission through a sexual intercourse is also possible. Since the majority of patients are in reproductive ages, involvement of fallopian tubes and endometrium cause infertility in patients. Cases: Reviewing 4 cases of female genital tuberculosis, which referred to an infertility treatment center with various symptoms, we encountered various appearances on hysterosalpingography (HSG. Conclusion: The genitourinary tract is the most common site of extra pulmonary TB. The primary focus of genital tuberculosis is fallopian tubes, which are almost always affected bilaterally but not symmetrically. Because of common involvement of fallopian tubes and endometrial cavity, disease causes infertility. Diagnosis is not easy because genital tuberculosis has a wide range of clinical and radiological manifestations with slow growing symptoms. Detailed hysterosalpingography finding may be helpful in better diagnosis of the disease. This case series aims to depict the various hystrosalpingographic appearances and pathology produced by tuberculosis and related literatures are reviewed in order to establish a better diagnostic evaluation of genital tuberculosis

    The authors report 2 cases of gangliogliomas of the sellar region, one of which was associated with chromophobe adenoma. Case 1. A 14-year-old female was admitted for a visual disturbance. Neurological examination showed bitemporal hemianopsia and secondary optic atrophy. CT scan showed an isodense mass in the suprasellar region, with homogneous enhancement by contrast medium and an accompanying low-density area in the left thalamus adjacent to the enhanced tumor mass. The histological diagnosis of the surgical specimen was ganglioglioma. Case 2. A 52-year-old female was admitted under the diagnosis of pituitary adenoma. Neurological examination showed bitemporal hemianopsia and signs of acromegaly. Plain skull X-ray film showed sellar ballooning and decalcification of the posterior clinoid process. The tumor resected in the first operation was histologically diagnosed as chromophobe adenoma mixed with ganglioglioma. In the follow-up, she showed signs and symptoms of a recurrent tumor, which was revealed to be ganglioglioma without any recurrence of chromophobe adenoma in the subsequent operations. The CT scan before the second operation showed an isodense supraand intrasellar mass with marked enhancement. Ganglioglioma is a rare, benign, nerve-cell tumor, mostly occurring in childhood and adolescence. The CT findings, together with the clinical history, the age of the patient, and the tumor location, may suggest the tentative preoperative diagnosis of ganglioglioma.

    Colorectal cancer screening can be performed by fecal occult blood testing,sigmoidoscopy,double contrast barium enema or colonoscopy. Colonoscopy has the significant advantage that polyps can be removed during the same procedure. Occasionally,colonoscopy can also reveal unexpected findings,including parasitic infections,even in asymptomatic patients. Tapeworms or cestodes are hermaphroditic parasites,which can live for considerable periods of time in the human gastrointestinal tract. Fish tapeworm (Diphyllobothrium species) are endemic in various parts of the world,the commonest species being Diphyllobothrium latum. Humans are the main definitive host for D. Latum and the majority of individuals harbouring the parasite are asymptomatic,while 40% of infected individuals may have low vitamin B12 levels. We describe a case of D. latum infection found on routine colonoscopic screening for colorectal cancer in an asymptomatic patient,which was successfully treated with praziquantel. The infection likely arose following raw fish (sushi) consumption.

    Subacute necrotizing myelopathy(SNM) is a rare non-tumorous disease of spinal cord characterized by subacute clinical course of progressive neurological deterioration. We report MR findings of a patient with pathologically proved SNM. 1 case of pathologically proved subacute necrotizing myelopathy. The patients was a 56-year-old man with progressive motor weakness and sensory loss of the lower extremities, and urinary and fecal incontinence for 11 months. Spine MRI revealed diffuse enlargement of the thoracic spinal cord from T2 to T7 level. Signal intensity of the expanded spinal cord was isointense relative to normal cord on T1-weighted image and hyperintense on proton-density and T2-weighted images. On contrast enhanced T1-weighted image, there was diffuse homogeneous enhancement in the expanded cord lesion. MR demonstration of stable persistence of spinal cord lesion or atrophy over months or years with clinical findings of gradual progressive neurologic deterioration may be helpful in the diagnosis of SNM.

    We describe an innovative program at the University of California, Davis for students to engage in clinical needs finding. Using a team-based approach, students participated in clinical rotations to observe firsthand the needs of clinicians at the university affiliated medical center. The teams were asked to develop documentary-style videos to capture key experiences that would allow future viewers to use the videos as “virtual” clinical rotations. This was conceived as a strategy to allow students in prohibitively large classes, or students in programs at institutions without associated medical or veterinary school programs, to experience clinical rotations and perform needs assessments. The students' perspectives on the experience as well as instructor analysis of best practices for this type of activity are presented and discussed. We found that the internship experience was valuable to the students participating, by not only introducing the practice of needs finding but for increasing the students' confidence in the practice of engineering design and their ability to work independently. The videos produced were of such high quality that instructors from other institutions have requested copies for instructional use. Virtual clinical rotations through video experiences may provide a reasonable substitute for students who do not have the ability to participate in rotations in person. PMID:23483373

  15. Brain MRI findings in two cases with eclampsia

    International Nuclear Information System (INIS)

    Neurological complications in patients with eclampsia are varied and include headache, visual disturbances, focal neurological deficits, altered mental status and coma. Occasionally, a focal neurological deficit includes a variety of visual disturbances. The pathophysiology of CNS abnormalities in patients with eclampsia is uncertain. Our cases, combined with a review of the literature, demonstrate that there is no correlation among severity of hypertension, parity, and location of lesions at initial magnetic resonance (MR) imaging findings or between the severity of hypertension and neurological symptoms. Two typical patterns are seen on MR images of patients with eclampsia. Lesions in the region of the posterior cerebral circulation are most common and are frequently associated with visual disturbances. Although there are lesions in the deep white matter or basal ganglia, a focal neurological deficit or alterations in mental status may not develop. This demonstrates the sensitivity of MR imaging in the detection of abnormalities in patients with eclampsia, even those without neurological deficits. 13 refs., 1 tab., 2 figs

    The process of case-finding was studied in 100 consecutive patients with pulmonary tuberculosis treated by the Chest Clinic, Penang Hospital. The median time from the onset of the illness until the initial medical consultation was two weeks (patient's delay). This delay was longer in males, patients with lower than secondary education and drug abusers. Only 47% of patients were put on treatment with a correct diagnosis within one month of the first consultation (doctor's delay). Almost all patients had at least one symptom suggestive of tuberculosis at presentation and the mean number of consultations before diagnosis was three. Patients who first visited government medical facilities had shorter doctor's delay than those who first saw private practitioners, and patients who first consulted a private practitioner were the least likely to be appropriately investigated by sputum examination and chest radiography. The median total delay was three months and at the time of diagnosis, 95% of patients had moderate or far advanced disease radiologically. In order to shorten doctor's delay, all medical practitioners, especially those in the private sector, should be made aware of the importance of early diagnosis and the proper management of tuberculosis. Health education campaigns for the public should also be undertaken to shorten patient's delay.

    Full Text Available Software testing is one of the important stages of software development. In software development, developers always depend on testing to reveal bugs. In the maintenance stage test suite size grow because of integration of new technique. An addition of new technique force to create new test case which increase the size of test suite. In regression testing new test case may be added to the test suite during the whole testing process. These additions of test cases create possibility of presence of redundant test cases. Due to limitation of time and resource, reduction techniques should be used to identify and remove them. Research shows that a subset of the test case in a suit may still satisfy all the test objectives which is called as representative set. Redundant test case increase the execution cost of the test suite, in spite of NP-completeness of the problem there are few good reduction techniques have been available. In this paper a new approach for test case reduction is proposed. This algorithm use genetic algorithm technique iteratively with varying chromosome length to reduce test case in a test suit by finding a representative set of test cases that are fulfill the testing criteria.

    A 43-year-old female presented with persistent headache and dizziness which had first occurred two years earlier. The physical and neurological findings at admission were unremarkable, though plain radiography revealed the presence of a dense calcified mass in the left frontal area, and CT showed that a homogeneous high-density nodule was attached to the inner surface of the left frontal skull. The hard bony mass found and excised during surgery was shown at histopathologic examination to be a subdural osteoma. We describe the clinicopathologic findings of this entity and discuss the radiological features which suggest its subdural location.

    The authors have encountered three cases of cystic meningioma among a total of 46 cases. Case 1. This 16-year-old boy complained of headache, nausea, and vomiting for about 5 months. He also felt double vision. On admission, the subjective complaints were headache, nausea, and vomiting, but there was no objective symptom. In CT scans a well-circumscribed low-density area with a nodule-like iso-density mass at the anterolaterally portion was shown in the left temporal rogion. This iso-density mass was homogenously enhanced in the contrast study. In an operation, approximately 60 ml of xanthochromic fluid was aspirated, and the nodule-like mass was totally removed. The histological diagnosis was meningothelial meningioma with a large cyst. Case 2. This 49-year-old woman had complained of blurred vision for 4 months before her admission. An ophthalmologist discovered a choked disc and referred her to our department. On admission a neurological examination disclosed a bilateral choked disc and disturbed visual acuity in her left eye. In CT scans, the mass, which was located in the right frontotemporal region, was markedly enhanced, and a small low-density lesion was recognized in it. Angiographically, a tumor stain fed by the middle meningeal artery was shown. The pathologic al diagnosis was angioblastic meningioma. Case 3. This 68-year-old woman, who had had several attacks of loss of consciousness within the 3 years before admission, had now complained of nausea and vomiting for one month. On admission, neurological examination disclosed paraparesis and paresthesia of the lt. lower limb. In CT scans an irregular mass contiguous to the falx was enhanced; it was surrounded by a low-density lesion which was considered to continue to the ependymal layer of the lateral ventricle. Multilobular cysts were found, and about 10 ml of xanthochromic fluid was aspirated . The histological diagnosis was angioblastic meningioma.

    Full Text Available Background: Renal papillary adenoma is usually an incidental finding at autopsy with an incidence of 7% to 23%. The frequency of small papillary tumours of kidney increases with age to approximately 40% of the population over the age of 65. These tumours occur morefrequently in scarred kidneys, acquired renal cystic disease and in children with von Hippel-Lindau syndrome. Case history: In this report we describe renal papillary adenoma incidentally detected during autopsies of two elderly males. Gross examination of kidneyshowed two tiny subcapsular yellowish nodules in one case and single nodule with similar morphology in the other. Microscopic examination in both the cases showed a well circumscribed tumour composed of densely packed tubules and papillae lined by small cuboidal to columnar cells with rounded uniform nuclei. However there was no nuclear atypia, mitosis or necrosis.

    "At first glance the lungs may seem uncomplicated, but many wise men have gone astray in their labyrinths." These words were written by Dr. A.A. Liebow, a famous pathologist, in a foreword to the first edition of Pathology of the Lung by H. Spencer. This same thought can also be applied to the field of medicolegal autopsies. 1. The gross appearance of the lungs in medicolegal autopsies Plucks consisting of the lungs, neck organs, the esophagus and the aorta were removed from human cadavers and after taking photos of the frontal and rear view, the lungs were carefully examined to reveal whether the lung shows characteristic morphological changes depending on causes of death. Based on their appearance, the lungs were classified into the 3 following types: a collapsed, a non-collapsed and an inflated type, each of these types reflecting the probable cause of death. The collapsed type of lung was seen in cases of death from exanguination, and the lung falling into shrinkage due to traumatic pneumo- and/or hemo-thorax was also classified into the collapsed type. The non-collapsed type of lung was seen in cases whose lungs were thermo-coagulated and in a case of death from a pulmonary embolism. Also, the deflating lungs of drowning victims before falling into collapse, were classified into a non-collapsed type. The inflated type of lung consisted of lungs that showed ballooning soon after death by drowning, and lungs that had inflated due to emphysema or edema from various causes. This lung study has reconfirmed that the lungs show hypostatic changes more clearly than any other organs of the body, and in the absence of skin color changes reflecting hypostasis, the settling of the blood in the lung could be detected in most cases. 2. Early histopathological lung changes induced by shock One hundred and thirty medicolegal cases were reviewed to detect early histopathological changes of the lung induced by shock. In many cases of death from various causes, pulmonary edema

    Epipericardial fat necrosis (EFN) is an infrequent cause of acute chest pain. In rare cases like these, conservative treatment is necessary. Clinically, EFN may mimic emergent cardiopulmonary conditions, such as acute myocardial infarction. Computed tomography (CT) and magnetic resonance imaging characteristics of EFN is well described as encapsulated fatty lesion with perilesional soft tissue strands and thickening of adjacent pericardium in the epipericardial area. For confirmation of the diagnosis, involution of this lesion on follow-up is important. We present a case of EFN observed with ultrasonography (USG). This lesion was shown as a well-defined ovoid shaped mass with heterogeneous echogenicity in the left side of cardiophrenic space on USG. There was no color flow on Doppler USG. Follow-up USG and CT revealed decrease in the size of the lesion.

    Vestibular schwannomas and meningiomas are the most common lesions of the cerebellopontine angle (CPA), accounting for approximately 85-90% of the tumors seen in this location. Lipomas are rare at this topography, representing about 0.15% of the CPA lesions. These tumors are mal developmental masses that arise from abnormal differentiation of the meninx primitive. Clinically, CPA lipomas can cause slowly progressive neurological symptoms and signs affecting cranial nerves or brain stem. Because these lesions usually are strongly attached to the surrounding structures, any surgical attempts of complete resection can result in neural or vascular damage, reinforcing the importance of the pre-operative imaging diagnosis. Although the CT findings of CPA lipomas can be typical, the magnetic resonance (MR) imaging, especially the fat suppression sequences, had improved the identification of these lesions. We aimed to report two patients with a CPA lipoma, emphasizing the MR imaging findings. (author)

  6. A critical review finds styrene lacks direct endocrine disruptor activity.

    Science.gov (United States)

    2015-01-01

    The European Commission lists styrene (S) as an endocrine disruptor based primarily on reports of increased prolactin (PRL) levels in S-exposed workers. The US Environmental Protection Agency included S in its list of chemicals to be tested for endocrine activity. Therefore, the database of S for potential endocrine activity is assessed. In vitro and in vivo screening studies, as well as non-guideline and guideline investigations in experimental animals indicate that S is not associated with (anti)estrogenic, (anti)androgenic, or thyroid-modulating activity or with an endocrine activity that may be relevant for the environment. Studies in exposed workers have suggested elevated PRL levels that have been further examined in a series of human and animal investigations. While there is only one definitively known physiological function of PRL, namely stimulation of milk production, many normal stress situations may lead to elevations without any chemical exposure. Animal studies on various aspects of dopamine (DA), the PRL-regulating neurotransmitter, in the central nervous system did not give mechanistic explanations on how S may affect PRL levels. Overall, a neuroendocrine disruption of PRL regulation cannot be deduced from a large experimental database. The effects in workers could not consistently be reproduced in experimental animals and the findings in humans represented acute reversible effects clearly below clinical and pathological levels. Therefore, unspecific acute workplace-related stress is proposed as an alternative mode of action for elevated PRL levels in workers. PMID:26406562

    Renal hemangioma is an uncommon benign tumor which usually causes painless or painful gross hematuria. Its preoperative diagnosis is extremely difficult or even impossible. We experienced three cases of renal hemangioma, located mainly at the pelvocalyceal junction or in the inner medulla. US demonstrated variable echogenecity, and CT revealed a lack of significant enhancement. Where there is gross hematuria in a young adult, especially when the renal mass located in the pelvocalyceal junction or inner medulla shows little enhancement on CT, renal hemangioma should form part of the differential diagnosis.

    A 44-year-old man was admitted to a hospital on August 1980, with chief complaints of high fever and consciousness disturbance. Three months later he was referred to our hospital. Neurological examination revealed mental deterioration, amnesia, bilateral pyramidal signs, tremor, truncal ataxia and others. Serum CF titer to Japanese encephalitis virus was 1 : 16. He was diagnosed as having Japanese encephalitis from the clinical features and serological response. CT scans showed low density areas in bilateral thalami, the left ganglia, left internal capsule, left substantia nigra and others. It is noticeable that the CT findings were compatible with the pathological changes of Japanese encephalitis.

    A retrospective study of eight young Cocker Spaniels aged 9-24 months was performed to describe the ultrasonographic findings of histologically confirmed renal dysplasia. Ultrasonography revealed kidneys of significantly (p imaging plane. In the other type of the ultrasound appearance, overall increased echogenicity with poor corticomedullary demarcation was noticed, and the kidneys could hardly be separated from their surroundings. These features were best recognised in the sagittal (coronal) imaging plane. In one dog with secondary hypercalcaemia, a hyperechoic corticomedullary area was also seen. Post-mortem histological diagnosis revealed renal dysplasia and secondary fibrosis. Based on ultrasound findings alone, renal dysplasia (renal familial disease) can be suspected when small kidneys with thin echogenic cortex are present in young dogs. An ultrasound image, similar to that of fibrotic kidneys (increased overall echogenicity and reduced corticomedullary definition) cannot be differentiated from chronic inflammatory disease and from end-stage kidneys. Therefore, ultrasound-guided biopsy or post-mortem histology is necessary for the definitive diagnosis of renal dysplasia. This is the first study reporting on the ultrasound appearance of renal dysplasia in Cocker Spaniel dogs. PMID:9557317

    Full Text Available Gliosarcoma (GS is a malignant neoplasm of the central nervous system that has coexisting glial and mesenchymal components. GSs are rarely related to osseous metaplasia. The authors report a case of GS in a male patient presenting apathy and catatonia. Computed tomography/magnetic resonance imaging showed an expansive process affecting the left frontal lobe. At microscopy, a malignant glioma constituted by highly atypical glial cells intermingled with spindle-shaped cells was identified. The lesion showed areas of necrosis with pseudopalisading formation, focus of osseous metaplasia, and positive immunoexpression of S100, CD99 and vimentin in both elements. Only the sarcomatous component exhibited negative immunoexpression of glial fibrillary acidic protein (GFAP. The diagnosis of GS was then established.

  13. Lipoid pneumonia: computed tomography findings - a case report

    International Nuclear Information System (INIS)

    The authors report a case of lipoid pneumonia in an 80 year old man with chronic constipation in regular use of mineral oil as a laxative. According to his family, he experienced coughing episodes when he took his medication. He also presented dyspnoea at rest and diminished consciousness levels. Chest radiographs showed a consolidation area in the posterior segment of right upper lobe, which did not change on successive exams. High resolution computed tomography demonstrated low-density consolidation with negative Hounsfield units (-29 to -83 UH) and ground-glass opacities in the right upper lobe and inferior lobes. These opacities predominated in the posterior regions of the lungs. The diagnosis was confirmed by the presence of oil material on bronchoalveolar washing. The patient was advised to discontinue the ingestion of mineral oil and did not return for follow-up. (author)

    Full Text Available There are structural and functional associations between hormone systems and central nervous system. Disturbances of thyroid hormone should cause neuropsychiatric symptoms. It is seen that there might be indistinct brain dysfunction symptoms in patients with euthyroid Hashimato disease. His neuropsychiatric profile assessed by examination and a battery included neuropsychiatric tests. Cancellation Test, Stroop Test TBAG form, Auditory Verbal Learning Test, Bender Gestalt Visual Motor Test and WISC-R tests were carried to patient. Failure in executive functioning and complex attention was determined in patient. In Bender Gestalt Visual Motor Test, perceiving of visual stimulus, visual motor coordination and predicating of perceived stimulus with motor functioning were significantly disordered. WISC-R subtests were also supporting these findings. Thyroid hormones and the problems with thyroid gland may cause some disturbances in neuropsychological profile. It should be helpful to see thyroid functioning tests in patients which referred with neuropsychological symptoms. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2013; 11: 146-9

    A 41-year-old male patient was admitted in our Ryukyu University Hospital complaining of parosmia. He had a history of miliary tuberculosis 21 years ago. Neurologically he showed left anosmia and hyperreflexia of the right upper extremity. Plain skull X-P and CT scan revealed a calcified mass, 25 mm in diameter, at the left frontal base. In MRI, the mass showed isointensity using the T/sub 1/ weighted inversion recovery sequence and heterogenously low intensity using the T/sub 2/ weighted spin echo sequence. Surgery was performed by bifrontal craniotomy. Then the tumor was removed totally including two coexisting small tumors. Histologically, they consisted of calcified caseous tissue and thick collagen capsule, suggesting old calcified tuberculomas. Postoperative course was uneventful and did not result in meningitis. Antituberculous therapy of streptmycin, isoniazid and rifapicin was given for 2 weeks, started on the operative day. MRI findings were presented in detail and the guideline of antituberculous therapy to the tuberculoma was discussed.

    A 44-year-old male was pointed out liver function abnormality by medical check-up. Blood examination and computed tomography showed liver cirrhosis. Then, he was referred to our hospital for further examination. After blood test, viral markers revealed previous infection of hepatitis B virus (HBV). We estimated the etiology of his liver disease as previous HBV infection. On laparoscopic examination, his liver surface was nodular with mixed yellowish nodules and ash gray to copper-colored nodules in the diameter of 3-10 mm. There were large regenerative nodules in segments 3 and 4. Large regenerative nodules and irregular steatosis were contradictory to HBV-related liver cirrhosis, so then we supposed Wilson's disease. The amount of copper excretion in the urine was 326.6 μg (>100 μg/24 h). After D-penicillamine administration, urinary copper excretion increased to 2151.5 μg/24 h. Though hepatic copper concentration was 174.5 μg/g wet tissue (>200 μg/g wet tissue), his laboratory data fulfilled the Leipzig diagnostic criteria proposed by EASL. Laparoscopic examination with liver biopsy has advantages to survey many disease-specific findings on liver surface and to obtain adequate liver sample. Laparoscopic examination is one of the effective procedures for diagnosing relatively rare liver disease like Wilson's disease.

    Schistosomiasis is a chronic worm infection caused by a species of trematodes, the Schistosomes. We may distinguish a urinary form from Schistosomes haematobium and an intestinal-hepatosplenic form mainly from Schistosomes mansonicharacterized by nausea, meteorism, abdominal pain, bloody diarrhea,rectal tenesmus, and hepatosplenomegaly. These infections represent a major health issue in Africa,Asia, and South America, but recently S mansoni has increased its prevalence in other countries, such as Europe countries and USA, due to international travelers and immigrants, with several diagnostic and prevention problems. We report a case of a 24-yearold patient without HIV infection, originated from Ghana, admitted for an afebrile dysenteric syndrome.All microbiologic studies were negative and colonoscopy revealed macroscopic lesions suggestive of a bowel inflammatory chronic disease. Since symptoms became worse, a therapy with mesalazine (2 g/d) was started,depending on the results of a bowel biopsy, but without any resolution. The therapy was stopped after 2 wk when the following result was available: a diagnosis of"intestinal schistosomiasis" was done (two Schistosoma eggs were detected in the colonic mucosa) and this was confirmed by the detection of Schistosoma eggs in the feces. Therapy was therefore changed to praziquantel(40 mg/kg, single dose), a specific anti-parasitic agent,with complete recovery. Schistosomiasis shows some peculiar difficulties in terms of differential diagnosis from the bowel inflammatory chronic disease, as the two disorders may show similar colonoscopic patterns.Since this infection has recently increased its prevalence worldwide, it was considered in the differential diagnosis of our patient with gastrointestinal symptoms.

    To meet the increasing demand for energy at reasonable cost, while minimizing the effects of energy production on the environment, the Pacific Northwest will actively pursue energy conservation as a source of energy. Bonneville Power Administration`s (Bonneville`s) goal is to save 660 average megawatts (aMW) by the year 2000 as its share of the Northwest conservation goal. Bonneville recognizes that a potential source of significant energy conservation is the industrial sector. Accordingly, in 1987, Bonneville began offering the Energy $avings Plan (E$P) Program to obtain electrical energy conservation in this sector. Combined annual savings for ail of the completed projects to date total over 104 million kilowatt-hours (kWh) per year. In terms of capacity, the program is saving about 11.9 aMW thus far. To date, the program has made acquisition payments totalling $3,853,800 to 55 participants. The total installed cost of the projects is $38,178,100. The average project is saving 1,892,300 kWh/yr (1,482,900 kWh/yr excluding the largest project which saves 24,000,000 kWh/yr).

    Full Text Available Abstract Background This is the first description of the ultrasonographic findings in a cow with vascular hamartoma of the liver. Case presentation Ultrasonographic examination of a six-year-old Swiss Braunvieh cow revealed an excessive number of hypoechogenic blood vessels in the liver parenchyma and a thrombus in the right hepatic vein. The activities of the liver enzymes and the concentration of bilirubin were within the reference ranges. At postmortem examination, a poorly delineated, non-encapsulated lesion, measuring approximately 10 cm × 10 cm in diameter, was found in the right liver lobe. The cut surface of the lesion was sponge-like and contained extremely dilated blood vessels, one of which was occluded with a branching red thrombus. A vascular hamartoma of the liver with thrombosis was diagnosed based on the histological findings. Conclusions To our knowledge, this is the first description of the ultrasonographic findings of vascular hamartoma of the liver in a cow. Hamartoma should be considered part of the differential diagnosis in cows with an abnormally large number of blood vessels in the liver parenchyma. This case report broadens the spectrum of liver diseases and ultrasonographic findings of the liver in cattle.

    Summary Background Cysticercosis is a parasitic infection caused by the larval stages of the pork tapeworm, Taenia solium. The subcutaneous form of the disease is a relatively rare clinical entity. Despite its rarity, it is imperative for a radiologist to be aware of this subcutaneous form of the disease and its various radiological patterns while evaluating any subcutaneous swelling. In this paper, we aimed to describe a typical case of ‘subcutaneous cysticercosis involving the left anterior chest wall’ with high resolution ultrasound findings. We also discussed the role of other imaging modalities in a case of subcutaneous cysticercosis. To the best of our knowledge, our case is only the second documented case report of sonological evaluation of subcutaneous cysticercosis involving the left anterior chest wall and the first case with high resolution ultrasound images of the lesion. Case Report An 11-year-old male presented with a painless, subcutaneous swelling over the left anterior chest wall for the last 2 months. High resolution ultrasound showed a well-defined, thin-walled, cystic lesion with an eccentric, echogenic focus in the subcutaneous plane. On change of the posture of the patient, this focus showed mobility. The hypoechoic area surrounding this cyst showed significant exudative fluid collection with diffuse, floating echoes and thin, incomplete internal septations. The adjacent soft tissues were thickened and irregular, suggestive of edema. This was followed by an excision biopsy. Histopathological examination revealed cysticercus cellulose parasite with an extensive mixed inflammatory cell infiltrate in the surrounding tissue. The patient was also administered oral antihelminthic therapy. Repeat ultrasound examination at the end of this management regimen showed complete healing with no e/o any remnant or recurrent cystic lesion, abscess or edema in the subcutaneous plane. Conclusions Subcutaneous cysticercosis is a relatively rare form of

    Full Text Available The National Center for State Courts (NCSC recently promulgated 10 trial court performance measures, referred to as CourTools. Measures 2, 3, 4, and 5 provide a methodology by which court managers can examine their management and processing of cases. The measures include clearance rate (measure 2, time to disposition (measure 3, age of active pending caseload (measure 4, and trial date certainty (measure 5. The objective of this research was threefold. The first aim was to assess the viability of using the case management measures to examine case processing trends in a New Jersey (NJ urban trial court. Each measure was reviewed to determine the tool’s applicability to the criminal division of the court. The second objective (pursued as a parallel to the first was to present the findings in the same context as the CourTools’ framework to determine its practicality. The final goal was to serve as a platform for other courts on the national and international level that do not yet use performance measures. These courts, diverse as they are, may use the methodologies and findings of this case study as a reference and guide to develop their own program to measure the court’s productivity and efficiency. To that end, this case study sought to answer the following questions in determining the applicability of the CourTools to the selected court and by extension, its potential for more universal application to other court systems. First, what is the relevance of measurements to the courts and why is it important, if at all? Second, what are the CourTools? Third, can the measurement model be applied to an actual court and if so, how is it executed and illustrated in practice? Finally, what are the implications of the findings for the court in question, as well as, other courts that seek to incorporate the CourTools to measure performance?

  5. Chandra Finds Surprising Black Hole Activity In Galaxy Cluster

    Science.gov (United States)

    2002-09-01

    Scientists at the Carnegie Observatories in Pasadena, California, have uncovered six times the expected number of active, supermassive black holes in a single viewing of a cluster of galaxies, a finding that has profound implications for theories as to how old galaxies fuel the growth of their central black holes. The finding suggests that voracious, central black holes might be as common in old, red galaxies as they are in younger, blue galaxies, a surprise to many astronomers. The team made this discovery with NASA'S Chandra X-ray Observatory. They also used Carnegie's 6.5-meter Walter Baade Telescope at the Las Campanas Observatory in Chile for follow-up optical observations. "This changes our view of galaxy clusters as the retirement homes for old and quiet black holes," said Dr. Paul Martini, lead author on a paper describing the results that appears in the September 10 issue of The Astrophysical Journal Letters. "The question now is, how do these black holes produce bright X-ray sources, similar to what we see from much younger galaxies?" Typical of the black hole phenomenon, the cores of these active galaxies are luminous in X-ray radiation. Yet, they are obscured, and thus essentially undetectable in the radio, infrared and optical wavebands. "X rays can penetrate obscuring gas and dust as easily as they penetrate the soft tissue of the human body to look for broken bones," said co-author Dr. Dan Kelson. "So, with Chandra, we can peer through the dust and we have found that even ancient galaxies with 10-billion-year-old stars can have central black holes still actively pulling in copious amounts of interstellar gas. This activity has simply been hidden from us all this time. This means these galaxies aren't over the hill after all and our theories need to be revised." Scientists say that supermassive black holes -- having the mass of millions to billions of suns squeezed into a region about the size of our Solar System -- are the engines in the cores of

    Full Text Available Abstract Background Chondrodystrophic myotonia or Schwartz-Jampel syndrome is a rare genetic disorder characterized by myotonia and skeletal dysplasia. It may be progressive in nature. Recently, the gene responsible for Schwartz-Jampel syndrome has been found and the defective protein it encodes leads to abnormal cartilage development and anomalous neuromuscular activity. Case Presentation We report the clinical findings and the management of an 8-year-old boy with this disorder. The molecular findings confirm that the patient is a compound heterozygote with a different splicing mutation in each Perlecan allele. This resulted in a significant reduction in the production of the encoded normal protein. Conclusion We discuss the multi-disciplinary management of Schwartz-Jampel syndrome that will facilitate optimal care and timely intervention of patients with this disorder.

    Snakebites are a relatively common occurrence worldwide and are estimated to affect greater than 2.5 million humans annually, of whom more than 100,000 will die. Imaging manifestations associated with this entity have rarely been described in the scientific literature. We recently obtained a successful clinical outcome after gelatin sponge sheet embolization of the hepatic artery in the case of a snakebite which caused hemoperitoneum associated with hepatic necrosis and rupture. Until now, this type of complication after a snakebite has not been reported in the literature. We report the computed tomographic and angiographic findings in a case of a snakebite resulting in hemoperitoneum caused by hepatic rupture and necrosis with active bleeding. In conclusion, snakebites have complex venomous effects. They may lead to various changes in hemostasis. In our case, snakebite-induced coagulopathy by a Korean viper resulted in hepatic necrosis and rupture with active bleeding. To our knowledge, this is the first published case about CT findings of hepatic necrosis and rupture with active bleeding after a snakebite and should be recognized as a possible complication following snakebites. We report the computed tomographic and angiographic findings in the case of a recently obtained successful clinical outcome after embolization of the hepatic artery in the case of a snakebite causing hemoperitoneum associated with hepatic necrosis and rupture with active bleeding.

  8. Finding influential spreaders from human activity beyond network location

    Min, Byungjoon; Makse, Hernán A

    2015-01-01

    Most centralities proposed for identifying influential spreaders on social networks to either spread a message or to stop an epidemic require the full topological information of the network on which spreading occurs. In practice, however, collecting all connections between agents in social networks can be hardly achieved. As a result, such metrics could be difficult to apply to real social networks. Consequently, a new approach for identifying influential people without the explicit network information is demanded in order to provide an efficient immunization or spreading strategy, in a practical sense. In this study, we seek a possible way for finding influential spreaders by using the social mechanisms of how social connections are formed in real networks. We find that a reliable immunization scheme can be achieved by asking people how they interact with each other. From these surveys we find that the probabilistic tendency to connect to a hub has the strongest predictive power for influential spreaders amo...

    Full Text Available Identification of genetic variants responsible for complex disorders using association mapping is an active area of research. There are two broad classes of association methodologies: population-based case-control studies and family-based transmission analyses. While case-control analyses are more popular and in general, more powerful than family-based analyses, they suffer from some inherent limitations. Thus, it is of importance, to understand the implications of an association finding obtained from a case-control study design. This article discusses the relative advantages and disadvantages of the two classes of association analyses, particularly in the context of genetic diversity in Indian populations.

There have been few reports in the literature about ganglion cell tumors that arise from the spinal cord, pineal gland, cerebral hemisphere or cerebellum. We recently experienced a case of ganglioneuroblastoma that developed from the hypothalamus in 4-year-old boy. To the best of our knowledge, this is the first reported case of ganglioneuroblastoma in the hypothalamus. We report on this case and we present the neuroimaging and pathologic findings

    We present a case of retrorectal hamartoma (tailgut cyst). Imaging findings on ultrasound, computed tomography and magnetic resonance imaging, pathologic findings, as well as the diagnostic pitfalls during the patient's management are documented. As it is a rare lesion with a non specific clinical presentation, it is usually misdiagnosed. Our aim is to present image characteristics of these lesions in all modalities and include retrorectal hamartomas in our differential diagnosis in patients with lesions with similar image findings.

    A small number of cases of cigarette-smoking-associated respiratory bronchiolitis (RB) with positive findings on the chest radiograph have been reported in the literature. High-resolution computed tomography (HRCT) findings are available in even fewer cases. We describe the case of an asymptomatic female smoker presenting with a reticulomicronodular infiltrate on a routine chest radiograph. High-resolution CT was characterized by ground-glass opacities and centrilobular micronodules with an upper lobe predominance. Surgical biopsy revealed peribronchiolar lesions, with accumulation of brown pigmented macrophages in the lumen of alveolar and bronchiolar lumen, consistent with the pathologic diagnosis of RB.

    Full Text Available Intraductal oncocytic papillary neoplasm (IOPN of the pancreas is a rare pancreatic tumor. To date, there have been three case reports of IOPN which showed strong positivity on 18F-fluorodeoxyglucose positron emission tomography (FDG-PET, raising the possibility of distinguishing IOPNs from other intraductal papillary mucinous neoplasms (IPMNs using FDG-PET. However, all three cases had large tumors, approximately 10 cm in diameter, and there are no case reports of FDG-PET findings of small IOPNs, i.e. tumors the average size of malignant IPMNs (3–5 cm. We report two cases with IOPN of average size with FDG-PET findings. Computed tomography (CT showed a multilocular cystic lesion 4 cm in diameter with a mural nodule 1 cm in diameter (case 1 and a cystic lesion 5 cm in diameter with a papillary mural nodule 4 cm in diameter (case 2. FDG-PET showed abnormal uptake at the same location as the pancreatic tumor revealed by CT in both cases. The maximum standardized uptake values of the lesions were 3.4 and 4.2, respectively. Surgical resection was performed and the tumor was diagnosed as IOPN with carcinoma in situ (case 1 and IOPN with minimal invasion (case 2. FDG-PET may be useful for diagnosing malignancy in IOPN, as it is in IPMN. However, in our two cases, strong accumulation was not observed in the IOPNs, which were within the average size range of malignant IPMNs.

    CT (HRCT) findings of pulmonary cryptococcosis were reviewed in 10 patients. CT revealed multiple pulmonary nodular shadows in 8 cases. There were two types of the shape of the nodules that is well demarcated and shaggy margin one. They were distributed mainly in peripheral zone and lower lobe of the lung. The centilobular daughter nodule suggesting transbronchial spread were seen in 4 cases. Other findings were as follows: air space consolidation in 2 cases, ground-glass opacity in 5, pleural thickening in 2, and pleural effusion in one case. CT-pathologic correlations were carried out in 4 cases. Nodular opacity were corresponded to granulomatous inflammations with or without necrosis. Spicula and ground-glass opacity corresponded to organizing pneumonia with fibrosis and exudative changes in the adjacent alveolar air spaces, respectively. In conclusion, whenever we see pulmonary nodular opacity or opacities on CT, we should not forget the possibility of pulmonary cryptococcosis. (author)

    Full Text Available Abstract Objective To examine the diagnostic accuracy of standard clinical tests for the shoulder in recreational athletes with activity related pain. Design Cohort study with index test of clinical examination and reference standard of arthroscopy. Setting Sports Medicine clinic in Sheffield, U.K. Participants 101 recreational athletes (82 male, 19 female; mean age 40.8 ± 14.6 years over a six year period. Interventions Bilateral evaluation of movements of the shoulder followed by standardized shoulder tests, formulation of clinical diagnosis and shoulder arthroscopy conducted by the same surgeon. Main Outcome Measurements Sensitivity, specificity, likelihood ratio for a positive test and over-all accuracy of clinical examination was examined retrospectively and compared with arthroscopy. Results Isolated pathology was rare, most patients (72% having more than one injury recorded. O'Brien's clinical test had a mediocre sensitivity (64% and over-all accuracy (54% for diagnosing SLAP lesions. Hawkins test and Jobe's test had the highest but still not impressive over-all accuracy (67% and sensitivity (67% for rotator cuff pathology respectively. External and internal impingement tests showed similar levels of accuracy. When a positive test was observed in one of a combination of shoulder tests used for diagnosing SLAP lesions or rotator cuff disease, sensitivity increased substantially whilst specificity decreased. Conclusions The diagnostic accuracy of isolated standard shoulder tests in recreational athletes was over-all very poor, potentially due to the majority of athletes (71% having concomitant shoulder injuries. Most likely, this means that many of these injuries are missed in general practice and treatment is therefore delayed. Clinical examination of the shoulder should involve a combination of clinical tests in order to identify likely intra articular pathology which may warrant referral to specialist for surgery.

    Radiation-induced spinal cord gliomas are extremely rare. Since the first case was reported in 1980, only six additional cases have been reported.; The radiation-induced gliomas were related to the treatment of Hodgkin's lymphoma, thyroid cancer, and medullomyoblastoma, and to multiple chest fluoroscopic examinations in pulmonary tuberculosis patient. We report a case of radiation-induced spinal cord glioblastoma developed in a 17-year-old girl after a 13-year latency period following radiotherapy for nasopharyngeal rhabdomyosarcoma. MRI findings of our case are described.

  8. Sonographic findings and clinical significance of uterine synechiae in pregnancy: Report of 6 cases

    International Nuclear Information System (INIS)

    We analyzed the sonograms of 6 cases with uterine synechiae in pregnancy. The diagnosis was based on the clinical and sonographic findings. Previous curret age during the artificial abortion and/or after the spontaneous abortion had been done in 5 cases (83.3%). In all cases, uterine synechia in pregnancy was recognized asintra-amniotic sheet containing hypoechoic central zone and an hyperechoic outer layers. Y-shaped splitting of thehyperechoic outer layers was seen against the uterine wall. The placenta extended along the sheet in 4 cases. Uterine synechiae in pregnancy should be distinguished from amniotic band syndrome by the characteristic snographic findings, and unwarranted abortion of normal fetus should be avoided

    Full Text Available In this paper, we explore system dynamics as a useful approach to consolidate findings from case studies on business process change (BPC projects. We compile data from 65 BPC case studies to develop a system dynamics simulation model that helps us to investigate ‘employee morale’ as an important construct in BPC projects. We show that such simulation models consolidate the complex and often non-linear findings from BPC case studies in a way that makes it available to discourse among researchers, lecturers and students as well as BPC professionals. Thus, this paper contributes to knowledge management and learning by suggesting system dynamics as a valuable approach to illustrate and convey the complex relationships between important constructs in BPC. This paper also contributes to the domain of business process management by demonstrating the benefits of system dynamics as a way to review and consolidate the abundance of BPC case studies.

    Cystic fibrosis is a hereditary disease involving recessive transmission. The fundamental abnormality consists of the production of abnormal secretion from a variety of exocrine glands such as salivary and sweat glands and those of the pancreas, colon, and tracheobronchial trees. Cystic fibrosis is the most common lethal genetically transmitted disease among whites, but is uncommon in Asians, including Koreans. Although a case involving a Korean was reported in 1988, the focus was diagnosis rather than the radiological findings. In the case of cystic fibrosis we now describe, the focus is inverted: we emphasise the reported in 1988, focusing on radiologic findings.

    Malignant transformation is a rare and late complication of untreated chronic osteomyelitis. Known radiographic findings of the malignant transformation of chronic osteomyelitis are osteolytic or mixed sclerotic and osteolytic lesions with or without soft tissue mass. But its magnetic resonance (MR) imaging findings are rarely described in the literature. We experienced a case of an 82-year-old man diagnosed with squamous cell carcinoma arising from long standing chronic osteomyelitis of the tibia. Our case indicates that radiologists should consider the possibility of malignant transformation in patients with untreated chronic osteomyelitis, with enhancing soft tissue mass invading and extending through underlying bone cortex and medulla on MR imaging.

    Full Text Available Abstract Introduction Primary lymphoma of the liver is an extremely rare finding, with the few such cases reported in the literature to date describing indeterminate imaging findings, being focused more on computed tomography. To the best of our knowledge, there is no prior report describing magnetic resonance imaging scan findings with such a lesion. In the case reported here, magnetic resonance imaging gave us the opportunity to ascertain the correct diagnosis, confirmed by histopathology, thus avoiding unnecessary surgery or other treatments. Although this condition is rare, knowledge of magnetic resonance imaging findings will be invaluable for radiologists and other medical subspecialties that may face such cases in the future in helping to provide adequate management for affected patients. Case presentation A focal lesion was incidentally detected by ultrasound in a 75-year-old asymptomatic Albanian man being treated for benign hypertrophy of prostate. Chest and abdomen computed tomography scans did not reveal any abnormal findings besides a solid focal lesion on the right lobe of the liver and a mild homogenous enlargement of the prostate gland. Subsequently, magnetic resonance imaging of the upper abdomen was performed for better characterization of this lesion. Our patient was free of symptoms and his laboratory test results were normal. Conclusions The magnetic resonance imaging scan results showed some distinctive features that helped us to make the correct diagnosis, and were thus very important in helping us provide the correct treatment for our patient.

    Four cases of intraventricular tuberculoma (IVT) in children are here reported. In none of the patients was there clinical evidence pointing to the intraventricular location. CT scan findings comprised three stages of development, namely: immature, mature and old. Ependymal attachment and asymmetric hydrocephalus were present in three cases, meningitis in two and ependymitis in one. Septum pellucidum traction was clearly observed in two patients, strongly supporting an adhesive process characteristic of intraventricular tuberculosis. Following specific treatment, the tuberculomas remitted partially or entirely.

    We retrospectively analysed the clinical and CT findings of 24 cases with tuberous sclerosis with special emphasis upon the atypical presentation. The cases with classic clinical triad were accounted for in 21%, while 33% presented with atypical clinical features. The most common and characteristic CT finding is that of the subependymal calcified nodules of the lateral ventricle, which was seen in 85% of our cases. Cortical tuber and white matter lesions were demonstrated in 65% and 55%, respectively. Three cases showed cortical tuber and white matter lesion without subependymal tuber. The cortical tuber usually exhibited low density or calcified lesion, but showed high density in 2 cases. Other findings of tuberous sclerosis included intraventricular tumor, ventriculomegaly, and cortical atrophy. One case clearly demonstrated parenchymal tuber on MR imaging. In conclusion, diagnosis of tuberous sclerosis is usually made on the clinical bases initially. However, CT and MR are also diagnostic even in unusual clinical presentation such as unexplained retardation or epilepsy or when the classic clinical triad is incomplete. If only cortical tuber or white matter lesion is present, it is difficult to diagnose tuberous sclerosis and to differentiate from other cortical mass lesion. Therefore, careful evaluation is required with familiarity with the atypical appearance of the disease.

    Full Text Available Myofibroblastoma of the breast (MFB is a very rare benign stromal tumor. In recent years, increase in mammographic screenings has resulted in increased diagnosis of MFB. Most cases are old males and postmenopausal women. MFB may be confused as malignant, clinically, morphologically, or by imaging. Immunohistochemistry is essential for final diagnosis in these cases. We report a case of a pathologically diagnosed MFB in an 80-year-old male patient who had coexisting prostate cancer and describe its imaging characteristics, especially magnetic resonance imaging (MRI. In this paper, histopathological and MRI findings of the MFB were discussed.

  4. Acute appendicitis in children: ultrasound and CT findings in negative appendectomy cases

    International Nuclear Information System (INIS)

    To decrease the negative appendectomy rate in children, knowledge of the misleading imaging findings on US and CT in negative appendicitis cases is important. To evaluate the negative appendectomy rate and describe the imaging findings of US and CT that lead radiologists to misdiagnose acute appendicitis in children. From 2007 to 2013, 374 children operated for suspected appendicitis were proved to either have acute appendicitis (n = 348) or to be negative for appendicitis (n = 26) on pathological reports. Negative appendectomy rates were compared among imaging modalities, age groups and genders. We retrospectively reviewed US and CT findings from negative appendectomy cases. The overall negative appendectomy rate was 7.0% (26/374). There were no statistically significant differences among the subgroups. The most common misleading presentations on US were sonographic tenderness (9/16, 56%) and non-compressibility (9/16, 56%). The most common misleading finding on CT were the presence of an appendicolith or hyperdense feces (5/12, 42%). Periappendiceal fat inflammation was observed in only one case of negative appendicitis on US and on CT. Radiologists can misdiagnose children with equivocal diameters of appendices as having acute appendicitis when sonographic tenderness or non-compressibility is present on US and when an appendicolith or hyperdense feces is noted on CT. The possibility of negative appendicitis should be borne in mind when periappendiceal fat inflammation is absent or minimal in indeterminate cases. (orig.)

  8. A case of holoprosencephaly with atypical CT findings and no facial anomaly

    International Nuclear Information System (INIS)

    We report a case of a 3 month old female infant, presenting with an increased tension of the fontanelle, cramp and irritability. No abnormality was noted during the periods of her mother's pregnancy and delivery. Although the CT findings in this case apparently revealed seemingly the pattern of severe subdural effusion, the cerebral ventricle was proved to be single. Cerebral angiography showed the anterior cerebral artery running along the frontal base. The sylvian triangle was not formed in the arterial phase. In the venous phase, deep cerebral veins (straight sinus, internal cerebral and the Galen veins) were not visualized although a variety of abnormal vein net works were observed. Holoprosencephaly was diagnosed this time. In this case, the histological findings at the operation confirmed that the subdural effusion-like space on CT was actually the dorsal sac. As DeMyer mentioned, this case was compatible with the morphology of holoprosencephaly in that cerebral parenchyma was retroflexed in a posterior direction. The patient did not show any facial malformations and the CT findings were also atypical appearance. The definite diagnosis was, therefore, made possible only by cerebral angiography in this case.

Case-finding initiatives have been evaluated in primary care, but few studies have explored the views of service providers on implementing them in practice.Aim: To explore the views of primary health care providers on case finding for COPD.Methods: A total of 20 semi-structured interviews were conducted from March 2014 to September 2014 among general practitioners, nurses, and managers from practices participating in a large COPD case-finding trial based in primary care in the West Midlands, UK. Participants’ views were sought to explore perceived benefits, harms, barriers, and facilitators to implementing COPD case finding in practice. Interviews were transcribed and analyzed using the framework method.Results: Participants felt that case finding improves patient care but also acknowledged potential harms to providers (increase in workload and to patients (overdiagnosis. Insufficient resources, poor knowledge of COPD, and limited access to diagnostic services were viewed as barriers to diagnosis, while provision of community respiratory services, including COPD specialist nurses, and support from secondary care were thought to be facilitators. Participants also expressed a need for more education on COPD for both patients and clinicians.Conclusion: Care providers believe that early detection of COPD improves patient care but also has accompanying harms. Barriers to diagnosing COPD, such as insufficient expertise in primary care and limited access to diagnostic services in the community, should be explored and addressed. The knowledge and attitudes of the public about COPD and its symptoms should also be investigated to inform future education and awareness-raising strategies.Keywords: chronic

    Full text: In late 1996, a bat carer from Rockhampton died from diffuse encephalitis. She had sustained several scratches to her left arm by fruit bats over the preceding month. She initially complained of left arm pain and numbness but her condition rapidly deteriorated with loss of consciousness and death. Australian bat Lyssavirus (ABL) was detected in her cerebrospinal fluid and neutralising antibodies to classical rabies virus in her serum. Other viral serology was negative. Autopsy revealed neuronal intracytoplasmic eosinophilic inclusions and electron microscopy showed bullet shaped viral particles. A Tc-99m hexamethylpropyleneamine oxime (HMPAO) brain scan demonstrated extensive bilateral areas of severely reduced tracer uptake in both cerebral hemispheres with the subfrontal and parieto-occipital regions the worst affected. Importantly, there was excellent correlation with the magnetic resonance image which showed diffuse cortical high signal on all pulse sequences most marked in the parieto-occipital areas. The CT scan performed at presentation had been normal and an earlier MRI had shown only a small enhancing pontine lesion. This is the first reported case of human infection by the newly identified ABL that has previously only been isolated in fruit bats. The virus belongs to the Rhabdovirus family and Lyssavirus genus and joins six other genotypes, one of which is the classic rabies virus. It has now been identified in four species of Australian fruit bats from north Queensland to Victoria. There is a paucity of knowledge relating to the distribution and transmission of the virus and research is underway to determine the potential public health risk

  11. Generalized periodic EEG activity in two cases of neurosyphilis

    2006-01-01

    Full Text Available Neurosyphilis is a recognized cause of epileptic seizures and cognitive impairment, but is not usually associated with the finding of generalized periodic activity in the EEG. We report two similar cases characterized by progressive cognitive impairment followed by partial complex seizures, in whom the EEG showed generalized periodic activity. Both cerebrospinal fluid and the response to penicillin therapy confirmed the diagnoses of neurosyphilis in the two cases. The finding of EEG generalized periodic activity in patients with cognitive or behavioral disorders is usually associated with Creutzfeldt-Jakob disease, although there are other conditions, some of them potentially reversible, which may also present this EEG abnormality. Neurosyphilis has tended not to be included among them, and our present findings support the importance of first ruling out neurosyphilis in those patients with cognitive or behavioral disorders associated with generalized periodic epileptiform discharges.

    We systematically analyze audio key finding to determine factors important to system design, and the selection and evaluation of solutions. First, we present a basic system, fuzzy analysis spiral array center of effect generator algorithm, with three key determination policies: nearest-neighbor (NN), relative distance (RD), and average distance (AD). AD achieved a 79% accuracy rate in an evaluation on 410 classical pieces, more than 8% higher RD and NN. We show why audio key finding sometimes outperforms symbolic key finding. We next propose three extensions to the basic key finding system—the modified spiral array (mSA), fundamental frequency identification (F0), and post-weight balancing (PWB)—to improve performance, with evaluations using Chopin's Preludes (Romantic repertoire was the most challenging). F0 provided the greatest improvement in the first 8 seconds, while mSA gave the best performance after 8 seconds. Case studies examine when all systems were correct, or all incorrect.

    Full Text Available Osteoid osteoma is a small, benign osteoblastic tumor consisting of a highly vascularized nidus of connective tissue surrounded by sclerotic bone. Three-quarters of osteoid osteomas are located in the long bones, and only 7-12% in the vertebral column. The classical clinical presentation of spinal osteoid osteoma is that of painful scoliosis. Other clinical features include nerve root irritation and night pain. Osteoid osteoma has characteristic computed tomography (CT findings. Because magnetic resonance imaging (MRI findings of the osteoid osteomas causing intense perinidal edema can be confusing, these patients should be evaluated with clinical findings and other imaging techniques. In this study, we present X-ray, CT, and MRI findings of a case with osteoid osteoma located in thoracic 1 vertebra left lamina and transverse process junction leading to brachial neuralgia symptoms.

    Full Text Available Rationale. Contact investigation is an established tool for early case detection of tuberculosis (TB. In India, contact investigation is not often conducted, despite national policy, and the yield of contact investigation is not well described. Objective. To determine the yield of evaluating household contacts of sputum smear-positive TB cases in Rajnandgaon district, Chhattisgarh, India. Methods. Among 14 public health care facilities with sputum smear microscopy services, home visits were conducted to identify household contacts of all registered sputum smear-positive TB cases. We used a standardized protocol to screen for clinical symptoms suggestive of active TB with additional referral for chest radiograph and sputa collection. Results. From December 2010 to May 2011, 1,556 household contacts of 312 sputum smear-positive TB cases were identified, of which 148 (9.5% were symptomatic. Among these, 109 (73.6% were evaluated by sputum examination resulting in 11 cases (10.1% of sputum smear-positive TB and 4 cases (3.6% of smear-negative TB. Household visits contributed additional 63% TB cases compared to passive case detection alone. Conclusion. A standard procedure for conducting household contact investigation identified additional TB cases in the community and offered an opportunity to initiate isoniazid chemoprophylaxis among children.

    Full Text Available Parag Suresh Mahajan, Nazeer Ahamad, Sheik Akbar Hussain Department of Radiology, Al-Khor Hospital, Hamad Medical Corporation, Doha, Qatar Abstract: An autoamputated wandering calcified ovary (AWCO is an extremely rare cause of abdominal calcification in the pediatric population. We present the magnetic resonance imaging (MRI features of AWCO in a child. To our knowledge, the MRI features of AWCO have not been previously described in the published literature. Our case report indicates that the MRI findings are characteristic in the diagnosis of an AWCO and can completely obviate the need for invasive procedures in this mostly benign disease. An AWCO should be considered in all cases of mobile calcific opacities on radiographs in female patients. We advise that MRI be conducted in all suspected cases of AWCO for accurate and noninvasive diagnosis, and regular follow-up should be performed with ultrasound. The findings in our case report have the potential to change the course of investigations and management in suspected cases.

    Retinal hemorrhage is a well-recognized manifestation of child abuse found in many babies with shaken baby syndrome. The presence of retinal hemorrhage is generally associated with more severe neurological damage and a worse clinical outcome. MR imaging findings of retinal hemorrhages are not well described in the pediatric literature. We present a 6-month-old boy with new-onset seizures, subdural hemorrhage and bilateral retinal hemorrhages that were detected by MRI and confirmed by indirect ophthalmoscopy. This case demonstrates the MR imaging findings of retinal hemorrhages and the importance of radiologists being able to recognize these specific imaging features. (orig.)

  3. Pulmonary hamartoma. Correlation of CT and pathologic finding in 13 cases

    International Nuclear Information System (INIS)

    We studied correlation of CT and pathological findings of 13 cases with pulmonary hamartoma. Images of thin-slice-high resolution CT (HRCT) using bone algorithm in pulmonary hamartoma revealed loss of vascular connection, notching, lobulation and rim enhancement. In addition, popcorn calcification and scattered low density area suggesting fat tissue within tumors were confirmed. These findings were thought to reflect the pathologic features of pulmonary hamartoma. It is considered that HRCT images using bone algorithm could play a significant role in the diagnosis of small nodular lesions of the lung including pulmonary hamartoma. (author)

    Full Text Available Abstract Introduction Radionecrosis (post-radiotherapy laryngeal submucosal inflammation and necrosis is a complication of (chemo radiotherapy for hypopharyngeal cancer that is difficult to differentiate from tumor recurrence. Case presentation A 67-year-old Japanese man presented with a condition extremely difficult to diagnose differentially as radionecrosis or tumor recurrence after radiotherapy for hypopharyngeal cancer. Although tumor recurrence was suspected from clinical conditions and computed tomography findings, pathologic analysis revealed no evidence of tumor recurrence, and successful therapy with steroids and antibiotics reduced the mucosal edema. Conclusion Our findings emphasize the wide spectrum of radiographic presentation of radionecrosis after chemoradiation of stage IV hypopharyngeal cancer.

    Subacute combined degeneration (SCD) of the spinal cord is a neurological complication arising from vitamin B{sub 12} deficiency. Typical findings are demyelination and axonal loss of the posterior and lateral columns of the thoracic and cervical spinal cord, leading to sensory ataxia and paresthesia. Clinical and neurological features and MRI findings all contribute to the diagnosis of this entity. In the Korean medical literature, only one case of of SCD involving pre-treatment MRI has been reported. We describe one case of SCD in a post-gastrectomy patient who initially presented with progressive sensory abnormality in both upper and lower extremities and showed T2 hyperintensity in the posterior and lateral columns of the spinal cord; this diminished, with clinical improvement, after vitamin B12 therapy. Our report includes the MR images obtained during follow up. (author)

    Objective: To discuss the radiographic findings and diagnosis in lupus enteritis. Methods: 4 cases of lupus enteritis (male 1, female 3) were studied. Abdominal pain was the chief complaint in all these cases. Before and after steroid therapy, small bowel contrast study was performed. Results: In one patient abdominal plain film revealed slight dilatation of jejunum with air-fluid levels. Small bowel contrast study showed effacement and (or) nodules of the mucosal folds, thumb printing, spasm and some degree of rigidity and narrowing of the lumen. Clinical symptoms and radiographic findings became normal after steroid therapy. Conclusions: If a patient with systemic lupus erythematosus presents abdominal symptoms, small bowel contrast study should be done. It is important and helpful to assist the diagnosis, to decide therapeutic plan and to follow up the effect of treatment

    The Backwith-Wiedemann syndrome (BWS) is and unusual complex with variable clinical features. Major findings included defects in the abdominal wall, macroglossia and macrosomia. These features should be amenable to prenatal ultrasound detection. Serious complications are possible in the neonatal period, which may result from the hypoglycemia or the airway obstruction due to macroglossia. Accurate prenatal diagnosis allows optimum prenatal care and prevention of serious complications. We report a case of prenatally diagnosed BWS with omphalocele, macroglossia, nephromegaly and hepatic cyst.

Although the MRI findings of this lesion resemble those of sacrococcygeal teratomas, the presence of a cystic component located at the tip of the coccyx and associated sinus formation may help in diagnosing it. Cystic coccygeal medullary vestige should be entertained in the differential diagnosis of coccygeal cystic lesions. (orig.)

    Novel influenza A (H1N1) infection is a highly infectious disease, which has been rapidly spreading worldwide since it was first documented in March of 2009 in Mexico. We experienced and report two cases of Influenza A (H1N1) pneumonia, accompanied by chest radiographic and CT findings. The chest radiographs revealed diffuse haziness and extensive airspace consolidation, whereas the CT scans demonstrated multifocal areas of ground glass opacity and airspace consolidation with a CT halo sign.

    Objective: Solid pseudopapillary tumor of the pancreas (SPTP tumor) is a rare pancreatic neoplasm with low malignant potential, which usually affects female patients in the second or third decades of life. It is a non-functional, slow-growing neoplasm that very often reaches considerable size before the first symptoms appear. Symptomatology is frequently related to tumor size. Surgical excision is usually curative in most cases. Infrequently the tumor can appear in male patients or in aged women, which can make the diagnosis more difficult. Some patients develop liver metastases in the follow-up that can be resected. Our purpose is to review the radiological and pathological findings of SPTP with emphasis on these infrequent cases. Subjects and methods: The medical records and radiological findings of patients who underwent surgery for SPTP between 2000 and 2005 were retrospectively reviewed. Study eligibility required that patients had undergone surgical resection and that a SPTP had been pathologically proved. Results: Four cases of solid pseudopapillary tumor of the pancreas were diagnosed and treated in our institution in the study period. Two of the patients, developed on follow-up liver metastases, and peritoneal, hepatic, and nodal metastases, respectively. Conclusion: Solid pseudopapillary tumors are well-encapsulated neoplasms that usually have a good prognosis after surgical excision. A malignant behavior is uncommon and in this case lymph node involvement, hepatic metastases and occasionally peritoneal invasion may also occur. Resection of liver metastases can prolong the long-term survival of the patients.

  5. Chest radiography and thoracic computed tomography findings in children who have family members with active pulmonary tuberculosis

    International Nuclear Information System (INIS)

    Objective: The chest radiography and TCT findings in children who had contacted with adult family members with active pulmonary tuberculosis were compared. The contributions of thoracic computed tomography to the diagnosis of tuberculosis were investigated. Methods and material: The children who were 0-16 years old (n=173) and children of families with an adult member which was diagnosed as pulmonary tuberculosis were evaluated. The children were considered in two groups based on the absence (n=125) or presence (n=48) of complaints and/or ambiguous symptoms such as lack of appetite, mild cough, sweating, history of lung infection, low body weight and those with suspicious chest radiography findings (12 cases) were included in this study. Asymptomatic patients (n=125) did not undergo TCT. Patients who had positive PPD skin tests only received isoniazid. If the TCT demonstrated enlarged lymph nodes or parenchymal lesions, minimally active pulmonary tuberculosis was diagnosed and antituberculous treatment was given. Results and discussions: TCT revealed lymph node enlargement or parenchymal lesions in 39 children (81.2%). Of the 12 children whose CXRs revealed suspicious lymph node enlargement and/or infiltration, five had normal findings in TCT whereas the initial findings were confirmed in the remaining seven. These data suggest that there is a correlation between the presence of ambiguous symptoms in exposed children and TCT findings; chest radiography and TCT findings do not yield parallel findings. All the patients who received anti-TB treatment were resolved in the control examinations. Conclusion: In this study there is a correlation between presence of ambiguous symptoms and TCT findings, but the chest radiography and TCT findings do not yield harmony in exposed children with ambiguous symptoms (suspicious tuberculosis cases). These observations should be considered in children with symptoms similar to those of exposed children, but with no definite history of

  6. MR findings in cases of suspected impacted fracture of the femoral neck

    International Nuclear Information System (INIS)

    Purpose: To evaluate MR imaging of the hip in patients with a clinically suspected impacted fracture of the femoral neck in cases where conventional plain films show negative or equivocal findings. Material and Methods: Twenty-seven such patients were prospectively examined by MR imaging with a 1.0 T unit, within 24 hours of admittance to hospital. A coronal T1-weighted turbo spin-echo sequence (n=27), and a coronal STIR sequence (n=25) or a coronal T2-weighted turbo spin-echo fast saturation sequence (n=2) were used. The evaluations were made by 2 radiologists with experience in musculoskeletal radiology. Results: There were 6 patients with a petrochanteric fracture, 2 without and 4 with slight displacement. Five patients had an impacted fracture of the femoral neck, and 3 had a fracture of the superior pubic bone. Of 2 patients with advanced arthrosis, i had an impacted femoral neck fracture and the other a nondisplaced intertrochanteric fracture. There was 1 patient who had sustained a nondisplaced acetabular fracture with increased joint fluid and muscle contusions. Three patients had muscle contusions only. Two patients had bone marrow contusions only, while 2 others with advanced coxarthrosis had increased joint fluid only. Three patients showed normal findings. Our findings led to emergency surgery in 13 cases, and conservative measures directed to the specific MR findings in 14 patients. Conclusion: MR imaging should be the first modality of choice in examining patients with a clinically suspected impacted fracture of the femoral neck where conventional films show negative or equivocal findings.

    Aim: To present the neuroradiological and clinical findings of fourth-ventricular meningiomas to increase awareness of this entity. Materials and methods: The computed tomography (CT; n = 5), magnetic resonance imaging (MRI; n = 9) features and clinical presentations of 10 patients with pathologically documented fourth-ventricular meningiomas were retrospectively analysed. Results: All tumours appeared as well-demarcated masses in the fourth ventricle at CT and MRI. The tumour shape was round in eight cases (80%) and irregular in two cases (20%). The CT images of five cases showed predominantly isoattenuation in three cases and high attenuation in two cases, with a mean attenuation value of 52 HU. In addition, calcifications were seen in three cases. At MRI, nine masses were isointense (n = 6) or hypointense (n = 3) to grey matter on T1-weighted images and mildly hyperintense (n = 4), isointense (n = 3), hypointense (n = 1), and of mixed signal intensity (n = 1) on T2-weighted and fluid-attenuated inversion recovery (FLAIR) images. Signal voids were visible in two cases. Enhancement after injection of contrast material was marked homogeneous (n = 5) or heterogeneous (n = 5) on CT or T1-weighted images. Three tumours had mild peritumoural oedema. Three tumours were associated with obstructive hydrocephalus. The pathological subtype of the 10 meningiomas was fibromatous (n = 5), atypical (n = 2), and one each of transitional, psammomatous, and clear-cell type. Conclusion: Although fourth-ventricular meningioma is quite rare, it should be considered in differential diagnosis of neoplasms within the fourth ventricle. The relatively typical radiological appearance, combined the age and sex of patients, can suggest the diagnosis of fourth-ventricular meningioma.

    Full Text Available SETTING: South Africa has the third highest tuberculosis (TB burden in the world. Intensified case finding, recommended by WHO, is one way to control TB. OBJECTIVE: To evaluate the effectiveness and acceptability of a paper slip method for TB contact tracing. METHOD: TB patients were offered paper slips to give to their contacts, inviting them for TB screening. The number of contacts screened and the proportion diagnosed with TB was calculated. Contacts that returned to the clinic after receiving the slips were interviewed. A focus group discussion (FGD with TB patients was held to determine their acceptability. RESULTS: From 718 paper slips issued, a 26% TB contact tracing rate was found, with a 12% case detection rate. The majority (68% of contacts were screened within 2 weeks of receiving the slip. Age and gender were not significantly associated with time to screening. 16% of the contacts screened did not reside with the TB patients. 98% of the contacts said the method was acceptable. FGD findings show that this method is acceptable and may prevent stigma associated with TB/HIV. CONCLUSION: This simple, inexpensive method yields high contact tracing and case detection rates and potentially would yield additional benefits outside households.

    Objective: To describe key imaging findings in a series of cases of primary neuroendocrine tumors of the lung (NTLs), with emphasis on computed tomography changes. Materials And Methods: Imaging studies of 22 patients (12 men, mean age 60 years) with histopathologically confirmed diagnosis, evaluated in the author's institution during the last five years were retrospectively reviewed by two radiologists, with findings being consensually described focusing on changes observed at computed tomography. Results: The authors have described five typical carcinoids, three atypical carcinoids, three large-cell neuroendocrine carcinomas (LCNCs), and 11 small-cell lung cancers (SCLCs). Only one typical carcinoid presented the characteristic appearance of central endobronchial nodule with distal pulmonary atelectasis, while the others were pulmonary nodules or masses. The atypical carcinoids corresponded to peripheral heterogeneous masses. One out of the three LCNCs was a peripheral homogeneous mass, while the others were ill-defined and heterogeneous. The 11 SCLCs corresponded to central, infiltrating and heterogeneous masses with secondary pleuropulmonary changes. Calcifications were absent both in LGNCs and SCLCs. Metastases were found initially and also at follow-up of all the cases of LCNCs and SCLCs. Conclusion: Although some imaging features may be similar, radiologic findings considered together with clinical information may play a relevant role in the differentiation of histological types of NTLs.

    Full Text Available Abstract Background Zoonotic malaria caused by Plasmodium knowlesi is an important, but newly recognized, human pathogen. For the first time, post-mortem findings from a fatal case of knowlesi malaria are reported here. Case presentation A formerly healthy 40 year-old male became symptomatic 10 days after spending time in the jungle of North Borneo. Four days later, he presented to hospital in a state of collapse and died within two hours. He was hyponatraemic and had elevated blood urea, potassium, lactate dehydrogenase and amino transferase values; he was also thrombocytopenic and eosinophilic. Dengue haemorrhagic shock was suspected and a post-mortem examination performed. Investigations for dengue virus were negative. Blood for malaria parasites indicated hyperparasitaemia and single species P. knowlesi infection was confirmed by nested-PCR. Macroscopic pathology of the brain and endocardium showed multiple petechial haemorrhages, the liver and spleen were enlarged and lungs had features consistent with ARDS. Microscopic pathology showed sequestration of pigmented parasitized red blood cells in the vessels of the cerebrum, cerebellum, heart and kidney without evidence of chronic inflammatory reaction in the brain or any other organ examined. Brain sections were negative for intracellular adhesion molecule-1. The spleen and liver had abundant pigment containing macrophages and parasitized red blood cells. The kidney had evidence of acute tubular necrosis and endothelial cells in heart sections were prominent. Conclusions The overall picture in this case was one of systemic malaria infection that fit the WHO classification for severe malaria. Post-mortem findings in this case were unexpectedly similar to those that define fatal falciparum malaria, including cerebral pathology. There were important differences including the absence of coma despite petechial haemorrhages and parasite sequestration in the brain. These results suggest that further

    A second case of histoplasmosis in a captive mara (Dolichotis patagonum) from a colony at the wildlife park Africam Safari, Puebla, Mexico, is described, and the mara died with disseminated clinical form of the disease, affecting mostly the large intestine and adrenal. The pathological findings of this case 2 revealed severe granulomatous typhlocolitis and moderate granulomatous gastrohepatic lymphadenitis with numerous yeast-like cells, 2-4 mum in diameter, with a clear halo surrounding them inside the cytoplasm of macrophages, suggesting the parasitic form of Histoplasma capsulatum. Adrenocortical cells had abundant similar microorganisms in their cytoplasm without any associated lesion. Gomori's methenamine silver and periodic acid Schiff stained positively these microorganisms. Immunohistochemistry, using a rabbit anti-H. capsulatum serum, and transmission electron microscopy supported the diagnosis of H. capsulatum infection. PMID:19360479

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

  13. Brain CT and MRI findings of a long-term case of subacute sclerosing panencephalitis

    International Nuclear Information System (INIS)

    Our study involved a long-term case (ten years) of subacute sclerosing panencephalitis. The case began with a 23 year-old experiencing visual deterioration. During the course of his illness, amnesia, autism and abnormal behavior were observed without any myoclonus. On the electroencephalogram, periodic synclonous discharge was shown in the early stage of his illness and subsequently disappeared. The brain CT and the MRI disclosed diffuse lesions in both cortical and subcortical areas of the cerebral hemispheres. The location and spread of lesions were more clearly revealed by the MRI than the brain CT. These findings suggest that the MRI is more useful than the brain CT in the diagnosis of subacute sclerosing panencephalitis. (author)

    Despite the increasing implementation of standardized rape kits across jurisdictions, the medico-legal findings generated by these tools are often not related to positive criminal justice outcomes. Given that there has been no global investigation of the factors that might impede their successful use in cases of sexual assault, we conducted a review of relevant scholarly and "grey" literature from industrialized and less-developed regions. One key theme to emerge from the analysis concerned certain problematic practices and behaviors of professional groups involved in the various stages of the post-sexual assault process. We found that a lack of competence in handling sexual assault cases, contempt for women who have been victimized, and corruption among some forensic examiners, police, scientists, and legal personnel often have shaped the collection, processing, analysis, and use of medico-legal evidence. We discuss recent initiatives and future directions for research that might serve to address these issues.

    Giant cell interstitial pneumonia (GIP) is an exceedingly rare, debatable, perplexing, occupational lung disease, which most commonly affects individuals exposed to hard metal dust. We report a case of GIP in a 60-year-old man, scheduled for coronary artery bypass graft surgery and died during induction of general anesthesia despite all efforts to resuscitate him. Patient's relatives lodged complaint with the police alleging the negligence by the attending physicians. Despite inaccessible data pertaining to the occupation, clinical history, and radiographic findings, the diagnosis was GIP due to the presence of intra-alveolar, bizarre, "cannibalistic" multinucleated giant cells-the histologic sine qua non of GIP. To the best of our knowledge, this is the first case report of GIP in the world literature that was diagnosed on histopathologic examination of lung tissue obtained at medicolegal autopsy.

    In a computed tomography (CT) scan, fat deposition in the urinary bladder wall is seen as a linear hypoattenuating band surrounded by soft tissue density. It is uncommon, but is often seen in normal cases. However, there is no report of fat deposition in the urinary bladder wall in Korea. The authors encountered a 62-year-old male patient who showed an incidental hypoattenuating band in the urinary bladder wall on abdominal CT. The patient showed no clinical signs related to fat deposition in the urinary bladder wall. When the patient's previous abdominal CT was retrospectively reviewed, the same CT finding was seen. This linear hypoattenuating band within the urinary bladder wall should be considered as a normal CT finding, although it is uncommon.

    Reactive lymphoid hyperplasia is a rare disease that forms a mass-like lesion and is characterized by the proliferation of non-neoplastic, polyclonal lymphocytes forming follicles. We recently encountered 2 cases of reactive lymphoid hyperplasia of liver, both of which were asymptomatic and mimicked hepatocellular carcinoma by various imaging modalities. Based on the clinical impression of hepatocellular carcinoma, surgical resections were performed. Microscopic findings revealed that both lesions consisted of an aggregation of lymphocytes consisting of predominantly B-cells, with multiple lymphoid follicles positive for CD10 and negative for bcl-2, consistent with the diagnosis of reactive lymphoid hyperplasia. Polyclonality of both lesions was further confirmed by B cell receptor gene rearrangement study. The incidence of reactive lymphoid hyperplasia in the liver is exceedingly rare, and it is difficult to differentiate such lesions from hepatic malignancies based upon clinical grounds. The clinicopathological findings and literature review of this report may be helpful to improve the clinical decision-making.

    Tuberculosis (TB) case findings from 2012 nationwide TB surveillance data in Japan were reviewed for diagnosis delay, proportion of far-advanced cavitary lesions, coexisting human immunodeficiency virus (HIV) infection and diabetes mellitus (DM), and drug susceptibility'testing (DST). Among 21,283 new TB cases in 2012, 82.4% were detected when patients sought medical attention for TB symptoms or visited medical facilities for other chief complaints. Among 16,432 patients with pulmonary TB, 25.8% had only respiratory symptoms, 31.7% had both respiratory and non-respiratory symptoms, 16.7% had only non-respiratory symptoms, and 0.6% had unknown symptoms. The rest (25.2%) were asymptomatic. The proportion of patient and doctor delays among 12,197 symptomatic pulmonary TB cases was analyzed. A large proportion--approximately 25-30%--of patients aged 35-64 years with symptomatic pulmonary TB exhibited a patient delay of 2 months. Like patient delay, the proportion of patients with a total delay (i.e., the sum of the patient and doctor delays) of ≥ 3 months decreased after 55 years of age. Moreover, the proportion of patients aged ≥ 65 years with a doctor delay of ≥ 1 month was higher than patients aged lung cavities increased from 1.5% in 1975 to approximately 2% and remained stable from 1985 to 2007. From 2007 to 2012, 366 patients with HIV infection had newly notified TB, 314 (85.8%) and 52 (14.2%) men and women, respectively, including 76 (20.8%) non-Japanese patients. Newly notified TB cases with DM comprised 14.3% (3,036/ 21,283) of the total cases in 2012 : 16.4% (2,127/12,988) of men and 11.0% (909/8,295) of women. The surveillance system obtained DST results for 8,347 (74.1%) of 11,261 culture-positive pulmonary TB cases in 2012. Among previously untreated cases, the proportions of patients with multi-drug resistant TB, any isoniazid resistance, and any rifampicin resistance were 0.5%, 4.0%, and 0.6%, respectively; the proportions in previously treated

  1. CT scan findings in three cases of multiple sclerosis with homonymous hemianopsia

    International Nuclear Information System (INIS)

    Three cases of clinically definite multiple sclerosis manifested homonymous hemianopsia. A 35-year-old female, in whom right optic neuritis developed as the initial symptom, manifested right homonymous hemianopsia 4 months later followed by cerebral symptoms another 4 months later. A 25-year-old male developed sudden brain stem and cerebellar symptoms associated with right abducens palsy and right homonymous hemianopsia. In a 26-year-old female developed right homonymous hemianopsia 13 years after the first attack of recurrent optic neuritis. CT-scan in these three cases revealed the presence of a ''plaque'' located in the white matter of the left occipital lobe in cases 1 and 2 and in the left peririgone white matter in case 3 as the causative lesion for the right homonymous hemianopsia. These findings indicate that the optic radiation may be involved in multiple sclerosis resulting in homonymous hemianopsia. CT scan is of value in determining the location of the affected intracranial lesion in multiple sclerosis. (author)

    2014-01-01

    Music evoked autobiographical memories (MEAMs) have been characterised in the healthy population, but not, to date, in patients with acquired brain injury (ABI). Our aim was to investigate music compared with verbal evoked autobiographical memories. Five patients with severe ABI and matched controls completed the experimental music (MEAM) task (a written questionnaire) while listening to 50 "Number 1 Songs of the Year" (from 1960 to 2010). Patients also completed the Autobiographical Memory Interview (AMI) and a standard neuropsychological assessment. With the exception of Case 5, who reported no MEAMs and no autobiographical incidents on the AMI and who also had impaired pitch perception, the range of frequency and type of MEAMs in patients was broadly in keeping with their matched controls. The relative preservation of MEAMs in four cases was particularly noteworthy given their impaired verbal and/or visual anterograde memory, and in three cases, autobiographical memory impairment. The majority of MEAMs in both cases and matched controls were of a person/people or a period of life. In three patients music was more efficient at evoking autobiographical memories than the AMI verbal prompts. This is the first study of MEAMs after ABI. The findings suggest that music is an effective stimulus for eliciting autobiographical memories, and may be beneficial in the rehabilitation of autobiographical amnesia, but only in patients without a fundamental deficit in autobiographical recall memory and intact pitch perception.

    Cavernoma is a vascular hamartoma, which represents 10-20% of all central nervous system vascular malformations. The majority (80%) of them are supratentorial, while involvement of the cranial nerves and the optic pathways is extremely rare. The main clinical presentation of optochiasmatic cavernomas consists of chiasmatic apoplexy, which is a neurosurgical emergency. Here, we report a case in which the finding was incidentally detected in a 49-year-old man. We describe the imaging characteristics of the lesion in such a rare location, highlighting the role of magnetic resonance imaging (MRI) (specifically 3 Tesla) in the management of asymptomatic patients.

    MR imaging was found to be the most sensitive modality for the detection of spinal cord abnormalities in the acutely injured spine. Although it is reported that traumatic pneumomyelogram indicates a base-of-skull or middle cranial fossa fracture and is almost certainly associated with intracranial subarachnoid air, early MR imaging may demonstrate subarachnoid air in penetrating trauma of the spinal cord without head injury. We report two cervical-spine stab-wound cases, one of which had subarachnoid air on early MR findings. (orig.)

    Full Text Available The Arnold-Chiari malformation is a congenital abnormality of CNS, characterized by downwarddisplacement the parts of the cerebellum, fourth ventricle, pons and medulla oblongata into thespinal canal. This malformation is one of causative factor of death in neonates and infants. Athorough understanding of the direct and indirect sonographic findings is necessary for diagnosis ofChiari II malformation in the developing fetus.In this case report, we present a Chiari malformation II detected at 23 weeks of gestation by routinelysonographic screening. The Role of prenatal sonography in recognition of the malformation andprognostic value of these features are discussed.

    Inflammatory pseudotumor, also known as inflammatory myofibroblastic tumor and plasma cell granuloma, is an uncommon low-grade lesion composed of spindle cells admixed with mature plasma cells and other inflammatory cells, such as histiocytes, lymphocytes, and eosinophils. Here, we describe the mammographic and ultrasonographic findings of a case of an inflammatory pseudotumor of the breast in a 60-year-old woman. With the suspicion of malignancy, core needle biopsy and surgical excision confirmed the mass as being an inflammatory pseudotumor of the breast.

    A case is reported of a 63-year-old female admitted to our hospital in Oct., 1986, with complaints of headache and visual field disturbance. A plain CT scan showed no abnormal low-density focal area. A contrast-enhancement CT scan, however, showed a localized linear abnormal enhancement in the right occipital lobe, without any mass-effect. A dynamic CT scan demonstrated a hyperemic perfusion pattern of the right occipital lobe. A visual-field examination showed left homonymous hemianopsia with concentric narrowing. These abnormal findings on CT, EEG, and ophthalmological examination disappeared within 3 weeks.

    We herein report an adult case of unicommissural unicuspid aortic valve (UAV). A 59-year-old man, who was noted to have a cardiac murmur at 31 years of age, was admitted to our hospital due to acute heart failure. Severe calcification in the aortic valve with severe low-flow/low-gradient aortic stenosis and moderate aortic regurgitation was observed and thought to be the cause of heart failure, however, the etiology of aortic valve dysfunction was not clear. Aortic valve replacement was subsequently performed, and unicommissural UAV was diagnosed according to the intraoperative findings. UAV is very rare congenital aortic valve disease which is rarely diagnosed preoperatively.

    Cavernoma is a vascular hamartoma, which represents 10-20% of all central nervous system vascular malformations. The majority (80%) of them are supratentorial, while involvement of the cranial nerves and the optic pathways is extremely rare. The main clinical presentation of optochiasmatic cavernomas consists of chiasmatic apoplexy, which is a neurosurgical emergency. Here, we report a case in which the finding was incidentally detected in a 49-year-old man. We describe the imaging characteristics of the lesion in such a rare location, highlighting the role of magnetic resonance imaging (MRI) (specifically 3 Tesla) in the management of asymptomatic patients.

    1988-06-01

    A clinical case of dentato-rubro-pallido-luysian atrophy (DRPLA) was reported. We established several aspects on the basis of MRI findings and a neuro-otological study. A 47-year-old woman had gait disturbance, involuntary movements, speech disturbance, and memory disturbance at the age of 42. She was admitted to the hospital because of worsening of the gait disturbance. Neurological examinations showed choreo-athetosis of the face, neck and upper extremities, mental disturbance, and scanning speech. However, she had neither ocular disturbance nor epilepsy or myoclonus. On the MRI-CT, an atrophy of midbrain and pontine tegmentum was observed. The neuro-otological study showed gaze nystagmus at the horizontal gaze, rebound nystagmus, hypometria of the saccade, saccadic pursuit, reduction of the optokinetic nystagmus, and increase in caloric nystagmus by means of visual input. A severe atrophy of the brainstem tegmentum and a mild atrophy of the cerebellar hemisphere and cerebral cortex are regarded as neuro-radiological features of DRPLA. Moreover, tegmental atrophy is related to ocular disturbance as a clinical feature. Various neuro-otological findings reveal many systems of ocular movements, i.e., a smooth pursuit system, a saccade system, and a vestibulo-ocular reflex system, involving flocculus. DRPLA can be clinically diagnosed by means of clinical features, MRI findings, and neuro-otological findings. A variety of neuro-otological abnormalities may indicate a progression of the ocular disturbance and a variety of lesions.

    Adenofibroma is an extremely rare benign m'ullerian mixed tumor composed of epithelium and mesenchymal cells. Most uterine adenofibromas occur in the endometrium, but they rarely protrude into the vagina. To date, only a few such cases with the imaging findings have been reported. Therefore, we report here on the sonographic and magnetic resonance (MR) imaging findings of a case of endometrial adenofibroma protruding into the vaginal cavity in a 28-year-old woman. The uterine adenofibroma appeared as a large intracavitary echogenic mass containing multiple small internal cysts, and it was distending the vaginal cavity on transrectal sonography. T2- weighted MR images showed a large intracavitary mass with heterogeneous high signal intensity protruding into the vaginal cavity. On gadolinium-enhanced T1-weighted MR images, heterogeneous septa-like enhancement was noted in the mass. Although uterine adenofibroma is extremely rare, adenofibroma can be suggested as a possible diagnosis when an intracavitary uterine mass, with multiple internal small cystic components and enhancing septa-like structures, is protruding into the vaginal cavity on imaging

  14. CT findings of pulmonary hamartoma : analysis of 16 histopathologically-proven cases

    International Nuclear Information System (INIS)

    CT findings of 16 patients with pulmonary hamartoma, histopathologically proven between 1990 and 1996, were retrospectively reviewed. Diagnosis was based on thoracotomy (n=11) or fine-needle aspiration biopsy (n=5). We analyzed the location, margin discreteness, shape, and size of the mass, and the presence of calcification or fat density, as seen on CT scan. All 16 tumors showed a discrete and smooth margin and there was no predilection for any specific site. They were lobulated (11/16, 69 %), round (4/16, 25%) or oval (1/16, 6%) and were of 16 cases (56%) showed calcification; this was either popcorn-type (n=3), stippled (n=3), eccentric (n=2), or diffuse (n=1). Five of 16 cases (31%) showed fat attenuation. On CT, pulmonary hamartomas showed a discrete margin, were lobulated (rather than round or oval) and varied in size. Calcification was more common than fat density. These CT findings may be useful for the differential diagnosis of pulmonary hamartoma. (author). 12 refs., 4 figs

  15. CT findings of mucoid impaction in 13 case: Speculation on their etiology

    International Nuclear Information System (INIS)

    Mucoid impaction presents a typical appearance on plain radiography and CT. If the lesion is multiple with manifestations of diffuse bronchopathy, it usually is a medical disease. On the other hand, if the lesion is single, an effort should be made to determine the underlying disease. The most frequent cause of the latter lesion is lung cancer, which generally can be depicted by CT. We retrospectively reviewed 13 cases of chest CT with obstructive mucoid impaction, in which CT and BFS(bronchofiberscopy) did not reveal a specific underlying cause. Women in the twenties and thirties were dominant and a past history of pulmonary tuberculosis was present in nine, BFS, done in nine, showed bronchial obstruction, and also luminal narrowing and cicatricial mucosal changes proximal to the obstruction in all them. Endobronchial tuberculosis was proven in only one case by bronchial wall biopsy. Lobectomy was performed in three. At the bronchial obstruction site, thickened bronchial walls were connected to proximal bronchi and there was no evidence of a clear underlying pathology except submucosal fibrosis in all three. The level of bronchial obstruction , determined by CT and BFS, was in the main bronchus in one, lobar bronchi in six, and divisional or segmental bronchi in seven, CT additionally showed calcific spots in their parenchyma connected to the bronchial obstruction in seven cases, and other changes suggestive of tuberculous origin in eight patients. In the context of the clinical history, BFS results, CT findings and pathologic findings of surgical specimen, most, if not all, of these 13 lesions are supported to be a sequela of endobronchial tuberculosis

    We report the case of a 60-year-old man with an accessory spleen in the pelvis. He visited our outpatient clinic because of abdominal discomfort. Computed tomography (CT) showed an enhanced mass (40 mm in diameter) in the pelvis. Preoperative diagnosis was difficult even after magnetic resonance imaging and colonoscopy. The patient underwent surgery for suspicion of a gastrointestinal stromal tumor or malignant lymphoma of the rectum. Intraoperative findings showed a mass in the pelvis and a long cord-like tissue reaching the mass and arising from the great omentum; the mass was excised. Histopathologic examination indicated that the mass was splenic tissue, and feeding vessels were found in the cord-like tissue, which were determined to be derived from the left gastroepiploic artery and vein. Thus, we diagnosed it as an accessory spleen in the pelvis. An accessory spleen is not rare and can occur anywhere in the abdominal cavity. However, an accessory spleen in the pelvis is an infrequent finding, and only 9 other cases of an accessory spleen in the pelvis have been reported. Therefore, it is very difficult to make a correct diagnosis preoperatively. However, 7 of the 9 cases (77.8 %) of a pelvic accessory spleen had vascular pedicles from the great omentum or splenic hilum as feeding vessels; hence, determining the feeding blood vessels on dynamic CT may be useful for diagnosing an accessory spleen in the pelvis. Additionally, if the accessory spleen is symptomatic or has a vascular pedicle, surgeons should attempt to resect the accessory spleen in the pelvis using minimally invasive laparoscopy.

    Objective: To present the computed tomography (CT) findings for the iliac veins of 10 patients who had left-sided lower extremity deep vein thrombosis due to iliac vein compression syndrome. Materials and methods: The CT findings for 10 cases of left-sided acute or chronic deep vein thrombosis caused by iliac vein compression syndrome were retrospectively evaluated. The patients were five women and five men (mean age {+-} S.D., 49.9 {+-} 15.6 years). In each patient with iliac vein compression syndrome, the diagnosis of the compression was established by venography performed during endovascular treatment. Diameter of the left common iliac vein was also measured in 14 control subjects without any lower extremity venous disease for comparison. Results: In all 10 cases, CT images in the transverse plane demonstrated the left common iliac vein being compressed by the overlying right common iliac artery. The mean diameter at the origin of the left common iliac vein (3.5 mm) in patients group was much smaller than the mean diameter of the same vein (11.5 mm) in the control group (p < 0.01). The mean percent stenosis of the left common iliac vein due to compression by the artery was 68%. Conclusion: Pelvic CT images in the transverse plane are useful for detecting iliac vein compression by the overlying right common iliac artery in patients with left-sided deep vein thrombosis. Radiologists should be aware of this imaging finding of iliac vein compression by the artery where the inferior vena cava bifurcates into the common iliac veins.

    Visceral leishmaniasis (VL, kala-azar) is a zoonotic infection caused by Leishmania species which are transmitted to humans by the bites of infected female phlebotomine sandflies. Leishmania infantum is the responsible species of VL in Aegean, Mediterranean, and Central Anatolia regions of Turkey mainly observed sporadically in pediatric age groups. The aim of this study was to evaluate the clinical and laboratory findings of adult patients with VL who were admitted to our hospital. A total of 10 patients (3 female, 7 male; age range: 18-67 years, mean age: 39.3 ± 16.51) followed in the infectious diseases clinic of the hospital between 2000 and 2013 were evaluated retrospectively. The diagnosis of VL was based on the presence of appropriate clinical and physical examination, as well as biochemical findings, positive serological test results (indirect fluorescent antibody test, and rK39 rapid antigen test) and/or detection of amastigote forms of parasite in the bone marrow aspiration samples. Of the cases three were diagnosed with both bone marrow and serology positivity, five with bone marrow positivity and one of each only with liver biopsy and positive serology result. Time interval from onset of the symptoms until the establishment of the specific clinical diagnosis was ranged from 2 to 12 weeks. The most frequent initial symptoms were fever, fatigue and abdominal distension. None of the patients had immunosupressive conditions such as HIV infection, corticosteroid use, immunosupressive treatment, or transplantation. All the patients were from Aegean region and six were living in rural areas. In all cases, hepatosplenomegaly, increased erythrocyte sedimentation rate, albumin/globulin ratio inversion, anemia, leukopenia and among nine cases trombocytopenia were detected. In one case acute renal failure has been developed before treatment and the patient was admitted to dialysis program. Bacterial superinfection occurred in two cases. Patients were treated with

    Full Text Available Context: Carcinoid tumors represent a group of well-differentiated tumors originating from the diffuse endocrine system outside the pancreas and thyroid. The overall prevalence of carcinoid tumors in the United States is estimated to be one to two cases per 100,000 persons. Various sites of origin of this neoplasm are appendix - 30-45%, small bowel - 25-35% (duodenum 2%, jejunum 7%, ileum 91%, multiple sites 15-35%, rectum 10-15%, caecum - 5%, and stomach - 0.5%. Liver metastases from jejunal and ileal carcinoids are generally hypervascular. Case report: Here we report a case of primary jejunal carcinoid tumor in a 66-year-old woman metastasizing to liver with ultrasonography, computed tomography, and diffusion-weighted magnetic resonance imaging (DWI findings. Conclusion: Primary jejunal carcinoid tumor is a rare entity. DWI can help in the differential diagnosis of hepatic hypervascular metastatic mass lesions from benign ones, as well as in the diagnosis of carcinoid tumor.

    OBJECTIVE To describe early diagnostic imaging findings in juvenile dogs with diskospondylitis. DESIGN Retrospective case series. ANIMALS 10 client-owned dogs history, examination findings, diagnostic test results, and imaging procedures were reviewed. Archived diagnostic images were retrieved and retrospectively evaluated. Data analysis was descriptive. RESULTS All dogs were evaluated for signs of vertebral pain ≤ 3 weeks after treatment for blunt trauma, bite wounds, or systemic illness. The earliest radiographic change was a narrowed intervertebral disk space (found for 28 disk spaces ≤ 2 weeks after evaluation for signs of vertebral pain); subluxation of adjacent vertebrae was identified for 8 of 28 affected disks, either initially or within the following 2 weeks. Vertebral end plate lysis was not an initial radiographic feature but was evident in follow-up radiographs. Ultrasonographic and transverse, multiformatted, volume-rendered CT images were obtained for 5 and 4 dogs, respectively. Ultrasonographic changes included ventrally bulging hypoechoic material at the affected disk site and loss of typical normal reverberation artifact in 4 dogs; these were detected prior to radiographic changes in 2 dogs. Affected disks on volume-rendered CT images had altered coloration in 3 of 4 dogs, and this was identified prior to radiographic changes in 1 dog. CONCLUSIONS AND CLINICAL RELEVANCE Juvenile dogs with a presumptive diagnosis of diskospondylitis had early imaging findings that were atypical, compared with the changes described for adult dogs with this condition.

    Brown tumors are focal reactive osteolytic lesions that are encountered in patients with primary or secondary hyperparathyroidism, and these tumors have nonspecific magnetic resonance (MR) imaging findings. However, there are only a few reports on MR imaging of brown tumors. The purpose of this study is to describe the spectrum of MR imaging findings of brown tumors. The MR imaging features of five patients with clinical and pathological evidence of brown tumor were retrospectively reviewed by two radiologists. The patients had primary hyperparathyroidism, which was confirmed as parathyroid adenoma (n = 2) and parathyroid carcinoma (n = 3). The MR images were evaluated for the presence of solid or cystic portions, the signal intensity of the lesions, the contrast enhancement pattern and the presence of cortex destruction and fluid-fluid levels. Twelve bone lesions were detected on the MR images of five patients; three lesions in two patients, four lesions in one patient, and one lesion in two patients. The tumor was solid in three lesions, mixed solid and cystic in four, and cystic in five. All the solid lesions were accompanied by mixed lesions. Discontinuity of the cortex and adjacent soft-tissue enhancement were seen in all the solid lesions. Fluid-fluid levels were seen in two cases within the cystic component of the mixed lesions and cystic lesions. The five patients with brown tumor demonstrated a wide spectrum of MR imaging findings. There are few lesions that are osteolytic on the radiographs and that show a short T2 on MR imaging, such as brown tumor. Multiple cystic or mixed lesions are the expected findings of brown tumors.

    32 consecutive patients suffering from chronic shoulder pain for more than 6 months after a single, nondislocating shoulder trauma were examined clinically and by special radiographs, dynamic sonography, MRI and arthroscopy. Typical complaints were pain during loading, especially during over......, arthroscopic labral resection and open subacromial decompression. In conclusion, patients with chronic posttraumatic shoulder pain have intraarticular injuries, especially tears of the glenoid labrum. History, clinical findings, radiography and sonography are seldom diagnostic. MRI is valuable, particularly...... the head activities. Symptoms of a "dead arm" and instability were also present. Patients with previous dislocations, traumas or radiographic signs of degenerative shoulder lesions were excluded. The patients had a decreased active range of motion and positive signs of apprehension and impingement...

    Although the thyroid gland is one of the most vascular organs of the body, metastatic disease in the thyroid is encountered infrequently. However, at autopsy, the incidence rate of thyroid metastasis ranges from 1.25% to 24%. The primary sites are the kidney, lung, breast, and gastrointestinal tract. We report a rare case of a hepatocellular carcinoma metastatic to the thyroid gland. The patient had multiple palpable masses in the anterior and left lateral neck along the internal jugular chain on physical examination 9 months after the initial diagnosis of liver tumor. These masses were confirmed as metastasis from hepatocellular carcinoma by ultrasonography-guided 16-G core needle biopsy. We discuss the sonographic findings of thyroid metastasis and their use as an additional aid for differentiating between unknown primary tumor and thyroid metastasis.

    We present the magnetic resonance imaging (MRI) findings in two males clinically diagnosed with iliotibial band friction syndrome (IBFS), a frequent cause of pain in the lateral compartment of the knee. Coronal T2-weighted images with fat saturation show an ill-defined area of high signal intensity in the soft tissues situated immediately below the iliotibial band lateral to the external condyle of the femur. No thickening of the iliotibial band or changes in its signal intensity were observed. Osseous edema and subchondral osseous erosion in the external condyle of the femur were observed in both cases. Pain in the lateral compartment of the knee might be due to multiple causes that should be included in the differential diagnosis and MRI can play a significant role in reaching the definitive diagnosis.

    Full Text Available Van der Woude syndrome (VWS is a rare developmental disorder with an autosomal dominant inheritance and variable expressivity, occurring in about 1 of every 1,00,000-2,00,000 people. This syndrome is remarkably variable. It is characterized by orofacial manifestations like lower lip pits, cleft lip and/or cleft palate, hypodontia, cleft or bifid uvula, syngnathia, narrow high arched palate, ankyloglossia and hyper nasal voice. We report two interesting cases of VWS with characteristic orofacial features and an unusual additional finding of bilateral commissural pits. The purpose of this article is to facilitate understanding of etio-pathogenesis, clinical manifestations, role of genetic counseling and with special emphasis on commissural pits as an additional feature in VWS.

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

    Eccrine poroma is a rare benign neoplasm of the eccrine sweat gland that usually presents as a small skin lesion such as a papule or nodule. This benign tumor has an overall good prognosis; however, eccrine porocarcinomas can arise from long-standing pre-existing benign eccrine poromas. We reported the case of a 37-year-old man with mental retardation who presented with an 8-cm pedunculated and densely pigmented eccrine poroma on the left hip. The tumor showed low signal intensity on T1-weighted MRI, with inhomogenously high signal intensity on T2-weighted images and strong contrast enhancement after intravenous gadolinium administration. It directly extended from the dermal layer, and the subcutaneous tissue was preserved. Radiologists should be aware that eccrine poromas could be large and pedunculated. Furthermore, related MRI findings and diagnostic clues should be carefully considered.

    Autopsy detected no tumor tissues in a patient who died 6.5 years after the diagnosis of glioblastoma multiforme. A 54-year-old male developed left hemiparesis one month prior to admission. Computed tomography demonstrated a cystic lesion in the right frontal region with irregular ring-like enhancement. The tumor was extensively removed together with the surrounding tissues followed by irradiation (whole brain 32.4 Gy, local 28.8 Gy), and intravenous administration of interferon-{beta}. Histological examination confirmed the diagnosis of glioblastoma multiform. He died of accidental head trauma 6.5 years after surgery. Autopsy of the brain detected no evidence of glioblastoma multiform. The only findings were cerebral edema and hematoma caused by head trauma, as well as histological changes due to radiation damage. This case apparently confirms the histological disappearance of tumor tissue in a long-term survivor with glioblastoma multiform. (author)

    We report the delayed sequelae arising in a case of electrical injury, reviewing the literature on the subject and focusing on the MRI findings of the brain. A 23-year-old male suffered burns to the left parietal scalp, both feet, and the anterior chest wall. Neurological symptoms and MRI abnormalities appeared 14 days after the insult and continued for about three months. T1-weight MR images demonstrated homogeneous hypointensity, while T2-weighted images depicted hyperintense finger-like projections. Contrast-enhanced T1-weighted images demonstrated strong band-like enhancement, indicating meningeal hyperemia. Follow-up MR imaging showed that the lesion had disappeared, indicating that the cerebral edema and meaningeal hyperemia were reversible.

Methylmalonic Acidemia: Diagnosis and Neuroimaging Findings of This Neurometabolic Disorder (An Iranian Pediatric Case Series. Iran J Child Neurol. 2013 Summer; 7(3: 63-66. ObjectiveMethylmalonic acidemia is one of the inborn errors of metabolism resulting in the accumulation of acylcarnitine in blood and increased urinary methylmalonic acid excretion. This disorder can have symptoms, such as neurological and gastrointestinal manifestations, lethargy, and anorexia.Materials & MethodsThe patients who were diagnosed as methylmalonic acidemia in the Neurology Department of Mofid Children’s Hospital in Tehran, Iran, between 2002 and 2012 were included in our study. The disorder was confirmed by clinical findings, neuroimaging findings, and neurometabolic and geneticassessment in reference laboratory in Germany. We assessed the age, gender, past medical history, developmental status, clinical manifestations, and neuroimaging findings of 20 patients with methylmalonic acidemia.ResultsEighty percent of the patients were offspring of consanguineous marriages. Half of the patients had Failure to thrive (FTT due to anorexia; 85% had history of developmental delay or regression, and 20% had refractory seizure, which all of them were controlled. The patients with methylmalonic acidemia were followed for approximately 5 years and the follow-up showedthat the patients with early diagnosis had a more favorable clinical response in growth index, refractory seizure, anorexia, and neurodevelopmental delay. Neuroimaging findings included brain atrophy, basal ganglia involvement (often in putamen, and periventricular leukomalacia.ConclusionAccording to the results of this study, we suggest that early assessment and diagnosis have an important role in the prevention of disease progression and clinical signs.References:1.

    2015-06-01

    A 34-year-old female was admitted at 34 weeks of gestation with sudden onset of a severe headache accompanied by vomiting. Neurological examination revealed neck rigidity, and computed tomography (CT) of the brain revealed a subarachnoid hemorrhage (SAH). Although the hemorrhage was located primarily in the left Sylvian fissure, computed tomography angiography (CTA) performed immediately after CT did not reveal any obvious vascular abnormalities such as an intracranial aneurysm. An emergency cesarean section was performed, and a healthy infant was delivered. Cerebral digital subtraction angiography (DSA) was performed the day following surgery, which revealed a saccular aneurysm measuring 4.3 mm × 2.4 mm in the left middle cerebral artery. Left craniotomy and clipping of the aneurysm were performed. The clot around the aneurysm was relatively solid. This case report is of significance given that initial CTA was negative for SAH during pregnancy, suggesting the requirement for immediate DSA or another CTA in such cases. There are many previous reports on false-negative CTA findings or disappearance and reappearance of aneurysms in SAH patients, and various biophysical and dynamic parameters are suggested to cause such phenomena. However, there are no reports on similar occurrences during pregnancy. Although the precise cause remains unclear, multiple factors associated with homeostasis during pregnancy were possibly associated with the transient disappearance in this patient. PMID:25732356

  14. Sustainability Management with the Sustainability Balanced Scorecard in SMEs: Findings from an Austrian Case Study

    Full Text Available Given the economic importance of small and medium sized enterprises (SMEs and their need for strategic sustainability management, this paper examines the concept of Sustainability Balanced Scorecard (SBSC with respect to SMEs. This case study describes the development of an SBSC in a middle-sized Austrian brewery. The existing methods used in SBSC creation were adapted to suit the company’s specific needs. The findings show that when developing an SBSC it is important to take specific SME characteristics into account and apply methods that allow for adaptation to the prevailing conditions, such as strategic management, organizational structure and resources. In the case study special attention was paid to strategy analysis and thereby the creation of a solid basis for the SBSC. Furthermore, the results show SBSC development is not a process of distinct consecutive steps, as it is often suggested in the literature, but rather that it is a complex process marked by iterative steps. Moreover, the paper highlights the supporting factors and challenges experienced. Whereas top management support, the presence of a project team and high employee involvement were identified as key supporting factors, a lack of specific resources and blurry strategy formulation exert negative influence on the development process. The results presented here should help other SMEs in their development of an SBSC. The paper stimulates scientific discourse on sustainability and strategic management by highlighting the relevant supporting factors and challenges.

  15. Septic osteitis of the distal phalanx: findings and surgical treatment in 18 cases

    International Nuclear Information System (INIS)

    Eighteen cases of septic osteitis of the distal phalanx were diagnosed clinically and confirmed at surgery over a 6 year period (1990-1996). Focal bone lysis was the most common radiographic finding. Sequestra were identified in 4 horses, one of which was associated with a fractured plantar process. All the horses were treated surgically with open debridement. The septic process recurred in 4 horses: one was subjected to euthanasia due to navicular bursa infection, secondary to a pathological fracture, the other 3 horses responded to further debridement. A pathological fracture occurred in another horse. All the survivors were not lame 3 months post operatively, although complete healing took 1-12 months. Long term follow up was available in 14 cases. One was retired, all the other horses were back in work at a similar level of performance. This series indicates that surgical treatment of septic pedal osteitis carries a fair to good prognosis despite a high rate of post operative complications and convalescence period of up to 12 months

    2009-07-01

    Full Text Available The serological methods for diagnosis of syphilis are classified into non-specific (non-treponemal such as Rapid Plasma Reagin (RPR, and specific (treponemal such as Treponema pallidum hemagglutination test (TPHA and Enzyme-linked immunosorbent assay IgG, IgM (ELISA IgG, IgM tests. The aim of this retrospective study was to estimate and compare the sensitivity and specificity of RPR, TPHA and Syphilis ELISA IgG, IgM. The study was conducted on 18 799 clinically healthy persons who had visited the Outpatient clinic of Ministry of the Interior Clinical Centre, Latvia during 2 years period from August 2006 to November 2007. Patients were screened to find out possible late latent syphilis cases by using RPR, TPHA and ELISA IgG, IgM assays. The results showed the highest sensitivity indices of ELISA IgG, IgM and TPHA methods, and the lowest for the RPR test. Highest specificity indices were observed by using ELISA IgG, IgM method followed by TPHA method with lower values and RPR method showing the lowest specificity. To conclude, ELISA IgG, IgM and TPHA methods should be used for screening late latent syphilis cases and ELISA IgG, IgM for diagnosis confirmation. RPR is not recommended for screening purposes.

    Full Text Available BACKGROUND: Lichen amyloidosus (LA is a primary localized cutaneous amyloidosis characterized clinically by discrete hyperkeratotic hyperpigmented papules and histologically by deposition of amyloid material in previously normal skin without any evidence of visceral involvement. AIMS AND OBJECTIVES: The aim of this work was to study the etiology, clinical features, histopathology and direct immunofluorescence findings in LA. METHODS: A prospective study of 30 patients with clinical, histological and immunofluorescence findings suggestive of LA was undertaken. After a detailed history and clinical examination, two punch biopsies for histopathology and immunofluorescence were taken. RESULTS: Of the 30 patients, 19 (63.3% were males and 11 (36.7% were females with duration of LA ranging from 6-20 months. Pruritus was the presenting symptom in 27 (90% patients. Shin was involved in 26 (86.7% followed by arms in three (10% and back in one (3.3%. Seventeen patients (56% had used scrubs for more than 2 years. Histopathology, direct immunofluorescence and Congo red staining detected amyloid in all cases. CONCLUSIONS: LA commonly presents over the shins as pruritic discrete hyperpigmented papules. Familial predisposition and friction may have a pathogenic role. Histopathological examination is very useful in the detection of amyloid which may be supplemented with direct immunofluorescence and Congo red staining.

    2014-01-01

    Full Text Available Human work provided for tourists is an indispensible element and, in a sense, the very soul of tourism services, and its quality highly influences what image is formed of the travel. By today, the significance of qualified human resources in tourism has been more and more appreciated in Hungary, as one of the conditions of realising internationally competitive tourism is the presence and development of quality human resources. Language knowledge and professional knowledge can make employees more qualified and more in demand both abroad and in the Hungarian labour market. Based on international statistics, it can be stated that the main target countries of Hungarian employees are Germany, Great Britain and Austria. The majority of Hungarian employees in these countries find jobs in the catering sector. The present study was conducted in 2012 with the aim of surveying the target countries of finding employment in case of the Szeged human resources of tourism. 874 people working in the Szeged tourism sector were involved in the survey. The data of the participants were examined according to local touristic structure, age group and highest school qualifications. The survey included those as well who had qualifications in tourism and catering.

    Bupropion is an atypical antidepressant that is structurally similar to amphetamines. Its primary toxic effects include seizure, sinus tachycardia, hypertension, and agitation; however, at higher amounts of ingestion, paradoxical cardiac effects are seen. We report the case of a 21-year-old woman who ingested 13.5 g of bupropion, a dose higher than any other previously reported. The patient presented with seizure, sinus tachycardia with prolonged QTc and QRS intervals, dilated pupils, and agitation. Four days after overdose, the patient's sinus tachycardia and prolonged QTc and QRS intervals resolved with symptomatic management, but she soon developed sinus bradycardia, hypotension, and mild transaminitis. With continued conservative management and close monitoring, her sinus bradycardia resolved 8 days after the overdose. The transaminitis resolved 12 days after the overdose. Our findings are consistent with previously reported toxic effects associated with common overdose amounts of bupropion. In addition, we have observed transient cardiotoxicity manifesting as sinus bradycardia associated with massive bupropion overdose. These findings are less frequently reported and must be considered when managing patients with massive bupropion overdose. We review the psychopharmacologic implications of this and comment on previous literature. PMID:27648505

    Scrub typhus is a well-known acute febrile illness caused by Orientia tsutsugamushi. This disease has multiorgan involvement, which includes the lungs, heart, liver, spleen, and the central or peripheral nervous system. Scrub typhus involving the central nervous system (CNS) is not rare. However, meningitis and meningoencephalitis can cause changes in mentation and death and are therefore associated with a poor prognosis. We report two consecutive cases of scrub typhus with CNS involvement. One patient presented with extensive white matter involvement, similar to that observed in acute disseminated encephalomyelitis, whereas the other patient presented with subependymal enhancement along the lateral ventricles. To the best of our knowledge, scrub typhus encephalitis, with extensive white matter involvement and subependymal enhancement, are very rarely described findings in the previous literature. Our patients did not show complete recovery, but the symptoms resolved with treatment. Recognizing these uncommon radiologic findings of scrub typhus may be helpful in the early diagnosis of scrub typhus with CNS involvement, which may alter the prognoses of patients.

    Reactive lymphoid hyperplasia is a rare disease that forms a mass-like lesion and is characterized by the proliferation of non-neoplastic, polyclonal lymphocytes forming follicles. We recently encountered 2 cases of reactive lymphoid hyperplasia of liver, both of which were asymptomatic and mimicked hepatocellular carcinoma by various imaging modalities. Based on the clinical impression of hepatocellular carcinoma, surgical resections were performed. Microscopic findings revealed that both lesions consisted of an aggregation of lymphocytes consisting of predominantly B-cells, with multiple lymphoid follicles positive for CD10 and negative for bcl-2, consistent with the diagnosis of reactive lymphoid hyperplasia. Polyclonality of both lesions was further confirmed by B cell receptor gene rearrangement study. The incidence of reactive lymphoid hyperplasia in the liver is exceedingly rare, and it is difficult to differentiate such lesions from hepatic malignancies based upon clinical grounds. The clinicopathological findings and literature review of this report may be helpful to improve the clinical decision-making. PMID:26191310

    Purpose: Compound diphenoxylate (diphenoxylate-atropine) poisoning can cause toxic encephalopathy in children, and magnetic resonance imaging (MRI) of the brain in this condition has not been reported. This study is to analyze brain MRI findings and to investigate the relations between MRI features and possible pathophysiological changes in children. Methods: Six children accidentally swallowed compound diphenoxylate, 4 males, 2 females, aged 20-46 months, average 33 months. Quantity of ingested diphenoxylate-atropine was from 6 to 30 tablets, each tablet contains diphenoxylate 2.5 mg and atropine 0.025 mg. These patients were referred to our hospital within 24 h after diphenoxylate-atropine ingestion, and underwent brain MRI scan within 24-72 h after emergency treatment. The characteristics of conventional MRI were analyzed. Results: These pediatric patients had various symptoms of opioid intoxication and atropine toxicity. Brain MRI showed abnormal low signal intensity on T1-weighted images (T1WI) and abnormal high signal intensity on T2-weighted images (T2WI) and fluid-attenuated inversion recovery (FLAIR) imaging in bilateral in all cases; abnormal high signal intensity on T1WI, T2WI and FLAIR in 4 cases. Encephalomalacia was observed in 3 cases during follow-up. Conclusion: In the early stage of compound diphenoxylate poisoning in children, multiple extensive edema-necrosis and hemorrhagic-necrosis focus were observed in basic nucleus, pallium and cerebellum, these resulted in the corresponding brain dysfunction with encephalomalacia. MRI scan in the early stage in this condition may provide evidences of brain impairment, and is beneficial for the early diagnosis, treatment and prognosis assessment.

  3. Liver hydatid cyst ruptured into the thorax: CT angiography findings of a case

    International Nuclear Information System (INIS)

    Full text: Introduction: Intrathoracic rupture of hepatic hydatid cyst is a rare but severe condition causing a spectrum of lesions to the pleura, lung parenchyma, and bronchi. Pulmonary complications result from the proximity of hydatid cysts in the liver and the diaphragm. Objectives and tasks: In this report we aimed to present computed tomography (CT) angiography findings of a case with liver hydatid cyst ruptured into the thorax. The patient underwent CT angiography examination with suspicion of pulmonary embolism. Materials and methods: A 71-year-old female patient admitted to our emergency department with complaints of severe and persistent cough. Basal region of the right hemithorax could not get breath sounds on physical examination. Chest radiography revealed the presence of consolidation-effusion. The patient was treated with antibiotherapy for pneumonia and parapneumonic effusion. Because of the clinical symptoms and chest radiograph findings persisted the patient underwent CT angiography examination with suspicion of pulmonary embolism. Results: On CT angiography images pulmonary artery and its branches were normal. There were subtotal collapse in the right middle and lower lung lobes and complicated cystic lesion that has air densities in the basal interlobar space. Another thick walled complicated cystic lesion with multiple septations and air densities was detected in the right posterior liver lobe. The right hemidiaphragm was interrupted and the right liver lobe partially herniated into the thorax cavity. Serologic tests were positive for Echinococcus granulosus and there were prior therapy history for liver cyst hydatid. The diagnostic aspiration findings were consistent with hydatid cyst lesion. Conclusion: In patients with hepatic hydatid cyst associated with persistent and severe cough, thoracic rupture of the cyst should be considered in differential diagnosis. CT angiography is fast, non-invasive and effective method in the detection of

    Full Text Available ENGLISH: The Human Rights Advisory Panel (HRAP established in 2006 to strengthen the accountability of UNMIK in Kosovo so far has dealt mainly with cases regarding property and missing persons. In two recent cases of members of the Egyptian and the Serbian minority (Fillim Guga and Nevenka Ristić it also dealt with privatization of socially - owned enterprises and found discrimination on ethnic grounds by the Special Chamber of the Supreme Court, established by UNMIK for such cases, which raises the accountability of UNMIK. In doing so the panel applied Article 14 of the ECHR on prohibition of discrimination in conjunction with Article 6 ECHR on fair trial in the light of relevant jurisprudence of the European Court of Human Rights. It also pointed out that in these cases the Special Chamber did not recognize a prima facie case of indirect discrimination and did not apply the principle of reversal of proof as required by the Anti - Discrimination Law of Kosovo. On behalf of UNMIK, the Special Representative of the Secretary - General defended the findings of the Special Chamber. The conclusions and recommendations in the Opinion of the Panel hold UNMIK accountable for the violations found and require it to take immediate and effective measures including an apology and adequate compensation for non-pecuniary damage as well as urging EULEX and other competent authorities in Kosovo to reopen the case by the Special Chamber. The work of the HRAP raises wider issues of accountability of international missions like UNMIK, to which it makes an important contribution.

    This paper describes and contrasts the implementation of Lean Thinking – a quality methodology that emphasises waste reduction and performing at higher levels of productivity with the same or less resources – into New Zealand's healthcare system. As the field is relatively new, three literature-based exemplar cases were developed to provide an analysis framework to analyse the three New Zealand research sites, which had activities, teamwork, leadership and sustainability as its core themes. Each research site's case was developed from primary data gathered through interviews, augmented by secondary data from project reports, District Health Board websites and media stories. The results highlight the benefits of a supportive quality-focussed organisational culture, executive management involvement and cross-functional teams as enablers. Further, work intensification and workplace resistance were also evident in varying levels within the sites. The study, while reiterating the problems of introducing quality methods from other domains into healthcare, presents the New Zealand context and reinforces that organisational preparedness as a significant factor which contributes to implementation success. This study goes beyond investigations of the use of Lean tools, changing improvement metrics and descriptive statistics to identify the contexts and variables which surround quality and process improvement implementations.

    There is limited understanding of why routine immunization (RI) coverage improves in some settings in Africa and not in others. Using a grounded theory approach, we conducted in-depth case studies to understand pathways to coverage improvement by comparing immunization programme experience in 12 districts in three countries (Ethiopia, Cameroon and Ghana). Drawing on positive deviance or assets model techniques we compared the experience of districts where diphtheria-tetanus-pertussis (DTP3)/pentavalent3 (Penta3) coverage improved with districts where DTP3/Penta3 coverage remained unchanged (or steady) over the same period, focusing on basic readiness to deliver immunization services and drivers of coverage improvement. The results informed a model for immunization coverage improvement that emphasizes the dynamics of immunization systems at district level. In all districts, whether improving or steady, we found that a set of basic RI system resources were in place from 2006 to 2010 and did not observe major differences in infrastructure. We found that the differences in coverage trends were due to factors other than basic RI system capacity or service readiness. We identified six common drivers of RI coverage performance improvement-four direct drivers and two enabling drivers-that were present in well-performing districts and weaker or absent in steady coverage districts, and map the pathways from driver to improved supply, demand and coverage. Findings emphasize the critical role of implementation strategies and the need for locally skilled managers that are capable of tailoring strategies to specific settings and community needs. The case studies are unique in their focus on the positive drivers of change and the identification of pathways to coverage improvement, an approach that should be considered in future studies and routine assessments of district-level immunization system performance.

    2013-10-01

    Full Text Available Introduction : The objective of this study was to give a description of the most prominent atypical radiological presentations of lung hydatidosis. Materials and methods: All patients diagnosed with pulmonary hydatidosis by surgical exploration were included in this study. Standard chest roentgenogram and computed tomography CT were evaluated before surgery for lung cysts or unknown lesions. Radiological findings were divided into two categories: 1- Typical hydatid cysts that were previously presented by imaging as a hydatid cyst in the form of an intact cyst, water lily sign and crescent sign. 2- Atypical hydatid cysts that were not similar to typical previously mentioned hydatid cysts. Results: During a 26-year period, 1024 subjects with pulmonary hydatidosis were diagnosed and operated on. Chest X-rays (interpreted in 832 cases showed perforated cysts in 190 (23% and atypical findings such as mass, alveolar type infiltration, abscess and collapse in 113 (13% patients. Seventy-nine patients had a thoracic CT scan in which atypical cysts were detected in 32 subjects (40.5% such as: thick wall cavity in 9 patients (28%, solid masses in 7 (21%, abscesses in 6 (18%, consolidation in 3 (9%, fungus balls in 3 (9%, collapse (atelectasis in 2 (6% and round pneumonia in 2 (6%. Cavity was significantly more frequent in the right lung (90% and mass-like opacity was significantly more frequent in the lower lung field (100%. Conclusion: Hydatid cysts should be considered for most of localized radiological pictures of the lung without respect to localization, size and count of lesions.

    Full Text Available Abstract Background The presentation and causes of adult meningitis in South Africa have changed substantially as a result of HIV. Knowledge of aetiology and laboratory findings in patients presenting with meningitis are important in guiding management. We performed a retrospective study to determine these findings in a setting of high HIV and TB prevalence in Cape Town. Methods Patients undergoing lumbar punctures between 1st January 2006 and 31st December 2008 at a public sector referral hospital were studied. Cases were classified by microbiological diagnosis, or in the absence of definitive microbiology as 1 normal CSF (neutrophils ≤ 1 × 106/L, lymphocytes ≤ 5 × 106/L, protein ≤ 0.5 g/dL, glucose ≥1.5 mmol/L, 2 minor abnormalities (neutrophils 2-5, lymphocytes 6-20, protein 0.51-1.0, glucose 1.0-1.49 or 3 markedly abnormal (neutrophils>5, lymphocytes>20, protein>1.0, glucose Results 5578 LPs were performed on 4549 patients, representing 4961 clinical episodes. Of these, 2293 had normal CSF and 931 had minor abnormalities and no aetiology identified. Of the remaining 1737, microbiological diagnoses were obtained in 820 (47%. Cryptococcus accounted for 63% (514 of microbiological diagnoses, TB for 28% (227, bacterial meningitis for 8% (68. Of the remaining 917 who had marked abnormalities, the majority (59% had a sterile lymphocytic CSF. Of note 16% (81 patients with confirmed Cryptococcus, 5% (12 with TB and 4% (3 with bacterial meningitis had normal CSF cell-counts and biochemistry. Conclusions Cryptococcal and tuberculous meningitis are now the commonest causes of adult meningitis in this setting. TB meningitis is probably underdiagnosed by laboratory investigation, as evidence by the large numbers presenting with sterile lymphocytic markedly abnormal CSFs.

    Classically air in the portal vein has been detected on plain radiography, but computed tomography and ultrasonography have been shown to be more sensitive. We report a case of air in the PV in a 10-day-old infant with pneumatosis intestinalis with its ultrasonographic and Doppler findings. The patient was a 10-day-old infant born by cesarean section at 41 weeks. Simple abdomen film revealed branching pattern of radiolucent air shadows within in contour of liver, gas distention of bowel loops and thickenod bowel walls with lincar intraluminal air shadows in abdomen, suggesting necrotizing enterocolitis. So we performed Doppler ultrasonography. Ultrasonography showed branching pattern of hyperechogenic dots and along the lumen of left portal vein. The color Doppler study revealed an aliasing duo to increased velocity and whirling pattern of blood flow, and the Duplex Doppler spectral display showed sharp, vertical bidirectional spikes by air in portal vein. Air in the portal vein can be easily diagnosed by the following signs: hyperechogenic dots in the portal vein on ultrasonography and vertical, sharp bidirectional spikes superimposed on the usual Doppler tracing of the portal vein on Duplex ultrasonography.

    Toluene and xylene are aromatic hydrocarbons commonly used as an industrial solvent for the manufacturing of pharmaceuticals, paints, and chemicals. The Occupational Safety and Health Administration has determined that toluene levels of 2000 parts per million (ppm) are considered dangerous to life and health. Several studies have examined the absorption of toluene and xylene following inhalation and oral ingestion in humans. Volatile organic compounds that are absorbed into the blood are distributed throughout the body; in particular, distribution of absorbed toluene and xylene in humans and rodents is characterized by preferential uptake in well-perfused and lipophil tissues such as the brain, liver, lungs, and body fat and also in central nervous system. The available studies indicate that xylenes are rapidly absorbed independently from the kind of exposition. We illustrate a fatal case of self-poisoning by ingestion of varnishes diluting solvents, reporting the identification and quantification of volatile organic compounds (toluene, o-m-p xylene) from human biologic liquids and viscera samples using the Solid-Phase Microextraction-Headspace-Gas Chromatography/Mass Spectrometry to toxicological analysis, and the histopathological findings evaluated in liver, kidney, and lungs.

    Full Text Available Thyroid hemiagenesis is a rare congenital anomaly in which one lobe of thyroid gland fails to develop. It is much rarer in males. There is a higher incidence of associated thyroid disorders in patients with thyroid hemiagenesis; therefore early and prompt diagnosis is important for children. We present the ultrasonographic and scintigraphic findings of thyroid hemiagenesis in an eight-year-old-boy. On ultrasonography (US, left lobe of the thyroid gland could not be demonstrated and the right lobe showed minimal hyperplasia. Its echogenicity was normal and no nodule was seen. On thyroid scintigraphy, left lobe of thyroid gland or any ectopic thyroid tissue could not be demonstrated, while the right lobe showed minimal hyperplasia. Without performing any invasive procedure, we enrolled the child in a follow-up program with the guidance of US and scintigraphy, which were effective both in making the final diagnosis of thyroid hemiagenesis and in evaluating the current status of the present thyroid tissue. In conclusion, if only one thyroid lobe is detected in a pediatric case initially with US or scintigraphy, the diagnosis of thyroid hemiagenesis should be suggested and, before any unnecessary or invasive attempt, the other complementary method (scintigraphy/US should be performed.

    Solitary Median Maxillary Central Incisor Syndrome (SMMCI) is a rare malformation syndrome consisting of multiple, mainly midline defects. Some authors suggest that it is a mild manifestation of the wide spectrum of holoprosencephaly, others classify it rather as a distinct entity. Authors report a case of SMMCI presenting with growth retardation, mild intellectual disability and absence of puberty. Cytogenetic and molecular cytogenetic investigations could identify no abnormalities. The presence of a single maxillary incisor called for further investigations to clarify hidden anomalies, these were empty sella, panhypopituitarism, hypothyroidism, and hypoplasia of the inner genitals. Based on the above findings, growth hormone, estrogen, and L-thyroxine substitution was introduced, which resulted in satisfactory longitudinal growth and onset of sexual maturation. We suggest genetic counselling and if needed, invasive investigations in female patients with short stature and absent/delayed puberty, with or without sex chromosomal anomalies, as the adequate therapy and even the quality of life of patient depends largely on the knowledge of their anatomical and endocrine status.

    2016-01-01

    Background: Street-connected youth and young adults (SCY) suffer a myriad of health problems. In Kenya, SCY are at high risk for tuberculosis (TB) due to their congregate living situations. TB screening is not routinely implemented in SCY and there has been no published literature on the burden of TB in SCY in western Kenya. Program description: In 2011, the AMPATH TB Program, an experienced TB screening program, partnered with the Tumaini Center, a trusted street youth organization, to conduct intensified case finding (ICF) for pulmonary TB among SCY. Our program aimed to investigate the numbers of SCY who reported symptoms and those diagnosed with smear-positive pulmonary TB, and link SCY with TB to treatment. Results: Of 116 SCY who were screened, 114 (98%) had a positive questionnaire; 104 (90%) provided a spot sputum sample, 39 (34%) provided a morning sputum sample, and 111 (97%) reported cough of >2 weeks. One street youth tested smear-positive for TB and was treated through to cure. Conclusions: Implementing TB ICF is feasible in low-resource settings through unique collaborations between health care programs and community-based organizations. In addition to identifying smear-positive TB, our program uncovered a high burden of respiratory symptoms among SCY in Eldoret, Kenya. PMID:27358809

    CT scans of the brain were taken 122 times in 43 children with acute leukemia. CT evidence of cerebral atrophy was seen in 58.1% (25/43) of the children. Of the children who were studied during initial antileukemic therapy, such as remission-induction therapy and CNS prophylaxis, 67.7% (21/31) also had CT evidence of cerebral atrophy. This high incidence was considered mainly due to the administration of the glucocorticoid hormone during the remission-induction therapy. Leukoencephalopathy developed in 11.6% (5/43) of the children. These 5 cases had CNS leukemia, systemic or intrathecal methotrexate administration, or CNS irradiation; the common factor was intrathecal methotrexate administration. Low-density areas in the cerebral white matter, ventricular dilatation, and intracerebral calcification were found on CT. The distribution of these areas was symmetrical (periventricular lucency), asymmetrical, or focal. Only 2 of these 5 children had intracerebral calcification; they survived more than 5 years after the onset of acute leukemia. CT was useful in evaluating 2 other asymptomatic children with low-density areas in the cerebral white matter. This finding was suggestive of preclinical or subclinical leukoencephalopathy.

    Full Text Available In this case report, we present the clinical findings and therapeutic outcomes of four rhino-orbital mucormycosis patients. The four patients (1 female, 3 male; age range, 55-77 years all had diabetes mellitus and two also had chronic renal failure. All patients exhibited proptosis, sinusitis, and dark-colored lesions on the nasopharynx and/or hard palate; three patients had ipsilateral peripheral facial paralysis. Visual acuity was no light perception in the two patients with severe orbital involvement and 0.8 in two patients with limited orbital involvement. Histopathological examination of the hard palate, nasopharynx or sinus biopsy revealed typical Mucor hyphae. Systemic liposomal amphotericin B was initiated in all patients. The patients with limited ocular involvement received amphotericin B both intravenously and by local irrigation; both patients had complete recovery. The other two patients underwent orbital exenteration; one patient died after declining systemic treatment postoperatively. Rapid diagnosis and treatment are important for the survival of rhino-orbital mucormycosis patients. With orbital involvement, surgical debridement and systemic and local treatment with antifungal agents may help avoid mutilating surgery like exenteration. (Turk J Ophthalmol 2015; 45: 169-174

  18. Primary papillary serous carcinoma of the peritoneum: Four cases and review of computed tomography findings

    International Nuclear Information System (INIS)

    Primary papillary serous carcinoma of the peritoneum is an uncommon primary malignancy of the peritoneum and is histologically indistinguishable from papillary serous carcinoma of the ovary. The diagnosis of primary peritoneal papillary serous carcinoma should be considered in the presence of peritoneal and omental masses in the absence of an ovarian mass. Although it has been extensively documented in the pathological and gynaecological oncology literature, the CT appearance of primary papillary serous carcinoma of the peritoneum has been reported in only 51 cases in five reports. We present four patients with CT findings of pathologically proven primary papillary serous carcinoma of the peritoneum. There were a total of 23 patients with a histopathologically proven diagnosis of primary papillary serous carcinoma of the peritoneum between 1980 and 2002 with CT imaging. However, only four of the 23 patients' CT films were retrieved for retrospective evaluation. The rest of the films were not available as either patients had misplaced the films or patients were deceased. Copyright (2004) Blackwell Science Pty Ltd

    A 63-year-old female was admitted to our hospital with bowel and bladder incontinence. Magnetic resonance imaging (MRI) showed a 13 × 12 × 12 cm mass invading the posterior regions of the L4, L5, S1 and S2 vertebrae with broad paravertebral soft tissue invasion. A Tru-cut biopsy of the mass was performed. The histopathological examination revealed metastatic follicular carcinoma of the thyroid. Thyroid functional tests were within the normal limits. Thyroid sonography revealed a heterogeneous, ill-defined, 14 × 9 mm hypoechoic solid nodule in the right lobe of the thyroid gland. On thyroid scintigraphy, an area of focal hyperactivity was detected in the right lobe at the nodule localization. Total thyroidectomy was performed, and the primary tumor pathology was determined to be follicular thyroid cancer. To our knowledge, only a few cases of lumbosacral cord compression as the initial manifestation of follicular thyroid carcinoma have been reported in the literature. We aimed to discuss the MRI findings of tumors in this age group with lumbosacral localization. PMID:23129029

    Synthetic cathinones are commonly abused novel psychoactive substances (NPS). We present a comprehensive systematic review addressing in vitro and in vivo synthetic cathinone pharmacokinetics, analytical methods for detection and quantification in biological matrices, and toxicological findings from human performance and postmortem toxicology cases. Few preclinical administration studies examined synthetic cathinone pharmacokinetic profiles (absorption, distribution, metabolism, and excretion), and only one investigated metabolite pharmacokinetics. Synthetic cathinone metabolic profiling studies, primarily with human liver microsomes, elucidated metabolite structures and identified suitable biomarkers to extend detection windows beyond those provided by parent compounds. Generally, cathinone derivatives underwent ketone reduction, carbonylation of the pyrrolidine ring, and oxidative reactions, with phase II metabolites also detected. Reliable analytical methods are necessary for cathinone identification in biological matrices to document intake and link adverse events to specific compounds and concentrations. NPS analytical methods are constrained in their ability to detect new emerging synthetic cathinones due to limited commercially available reference standards and continuous development of new analogs. Immunoassay screening methods are especially affected, but also gas-chromatography and liquid-chromatography mass spectrometry confirmation methods. Non-targeted high-resolution-mass spectrometry screening methods are advantageous, as they allow for retrospective data analysis and easier addition of new synthetic cathinones to existing methods. Lack of controlled administration studies in humans complicate interpretation of synthetic cathinones in biological matrices, as dosing information is typically unknown. Furthermore, antemortem and postmortem concentrations often overlap and the presence of other psychoactive substances are typically found in combination

    Clinicopathological findings from six cats with confirmed cholecystitis or acute neutrophilic cholangitis are presented. Historical findings included lethargy and anorexia or inappetence of up to five days duration. On physical examination all cats were pyrexic and four out of six were jaundiced and had cranial abdominal pain. Bile samples were obtained by cholecystocentesis at exploratory coeliotomy (two cases) or by percutaneous, ultrasound-guided cholecystocentesis (four cases). Gall bladder rupture and bile peritonitis occurred subsequent to ultrasound-guided cholecystocentesis in one case. The most common bacterial isolate was Escherichia coli (four cases); E coli was isolated alone in two cases, in combination with a Streptococcus species (one case) and in combination with a Clostridium species (one case). Streptococcus species alone was isolated from one case, as was Salmonella enterica serovar Typhimurium. The latter is the first reported case of Salmonella-associated cholecystitis in a cat. Concurrent pancreatic or intestinal disease was detected histologically in three cases. All cases were treated with antimicrobials based on in vitro susceptibility results. Treatment was successful in five cases. One cat with concurrent diffuse epitheliotropic intestinal lymphoma was euthanased. Percutaneous ultrasound-guided cholecystocentesis is an effective, minimally-invasive technique enabling identification of bacterial isolates in cats with inflammatory hepatobiliary disease.

    This paper provides a comprehensive analysis of how the European Emission Trading System (EU ETS) as the core climate policy instrument of the European Union has impacted innovation. Towards this end, we investigate the impact of the EU ETS on research, development, and demonstration (RD and D), adoption, and organizational change. In doing so, we pay particular attention to the rela-tive influences of context factors (policy mix, market factors, public acceptance) as well as firm characteristics (value chain position, technology portfolio, size, vision). Empirically, our analysis is based on multiple case studies with 19 power generators, technology providers, and project developers in the German power sector which we conducted from June 2008 until June 2009. We find that the innovation impact of the EU ETS has remained limited so far because of the scheme's initial lack in stringency and predictability and the relatively greater importance of context factors. Additionally, the impact varies tremendously across technologies, firms, and innovation dimensions, and is most pronounced for RD and D on carbon capture technologies and corporate procedural change. Our analysis suggests that the EU ETS by itself may not provide sufficient incentives for fundamental changes in corporate climate innovation activities at a level adequate for reaching political long-term targets. Based on the study's findings, we derive a set of policy and research recommendations. (orig.)

  3. Social impacts of community renewable energy projects: findings from a woodfuel case study

    International Nuclear Information System (INIS)

    There is much current interest in the potential of community-based renewable energy projects to contribute to transition towards low carbon energy systems. As well as displacing fossil fuel consumption by increasing renewable energy generation, projects are expected to have a range of social impacts which may result in additional positive sustainability outcomes. These include potential to increase: acceptance of renewable energy developments; awareness of renewable and sustainable energy technologies and issues; uptake of low carbon technologies; and sustainable/pro-environmental behaviours. To date however, there has been little investigation of whether and how these impacts occur. This paper presents results from qualitative research investigating the social impacts of a community woodfuel project as experienced by project participants and other local stakeholders. Findings show projects can raise awareness of renewable energy technologies and increase uptake of renewables. Overall the case study project successfully changed the local social context for development of woodfuel heating, reducing risk for all involved in the future development of this sector, particularly in the immediate locality. There was some evidence of increased engagement with wider sustainability issues but this was limited to direct participants, suggesting local projects need to be supported by wider systemic change to maximise impacts. - Highlights: ► We assessed the social impacts of a community woodfuel project. ► The project increased awareness and uptake of woodfuel heating. ► Impacts were achieved as a result of the locally-specific approach. ► Local projects can seed cultural change promoting transition to a low carbon society.

    Objective. To determine any changes in tuberculosis epidemiology in the last 15 years in Benin, seasonal variations, and forecasted numbers of tuberculosis cases in the next five years. Materials and Methods. Retrospective cohort and time series study of all tuberculosis cases notified between 2000 and 2014. The “R” software version 3.2.1 (Institute for Statistics and Mathematics Vienna Austria) and the Box-Jenkins 1976 modeling approach were used for time series analysis. Results. Of 246943 presumptive cases, 54303 (22%) were diagnosed with tuberculosis. Annual notified case numbers increased, with the highest reported in 2011. New pulmonary bacteriologically confirmed tuberculosis (NPBCT) represented 78%  ± SD 2%. Retreatment cases decreased from 10% to 6% and new pulmonary clinically diagnosed cases increased from 2% to 8%. NPBCT notification rates decreased in males from 2012, in young people aged 15–34 years and in Borgou-Alibori region. There was a seasonal pattern in tuberculosis cases. Over 90% of NPBCT were HIV-tested with a stable HIV prevalence of 13%. The ARIMA best fit model predicted a decrease in tuberculosis cases finding in the next five years. Conclusion. Tuberculosis case notifications are predicted to decrease in the next five years if current passive case finding is used. Additional strategies are needed in the country. PMID:27293887

    The authors report the findings of Aicardi syndrome, a disease of unknown etiology composed of multiple spasms, chorioretinal lacunae and agenesis of the corpus callosum. They present a case of Aicardi syndrome with characteristic clinical presentation and magnetic resonance imaging findings. The disease, despite being considered rare, has characteristic imaging findings. Over the past years magnetic resonance imaging has improved its ability in demonstrating other findings besides agenesis of the corpus callosum, making the radiologist's role very important in the diagnostic suspicion of this disease.

    Highlights: • We clinicopathologically reviewed 22 cases of early mucinous adenocarcinoma. • Radiologically, all cases showed solid or part-solid nodules. • Lobular-bounded margins were observed in 7 cases. • The radiological features could be histologically attributed to mucin production. • One-third of the cases were preoperatively misdiagnosed as inflammatory nodules. - Abstract: Background: The pathological criteria of early-stage mucinous adenocarcinoma of the lung have recently been defined; however, its characteristic radiologic imaging findings are still poorly understood. Thus, this study aimed to clarify the radiologic and pathological findings of early-stage mucinous adenocarcinoma. Materials and methods: In this study, we clinicopathologically reviewed 22 cases of surgically resected mucinous adenocarcinoma in situ (AIS) and minimal invasive adenocarcinoma (MIA), and attempted to elucidate the characteristic radiologic features of early mucinous adenocarcinomas using high-resolution computed tomography (HRCT). Results: Radiologically, the mean value of the maximum diameter of 22 tumours was 2.1 cm (range, 1.0–2.9 cm). Based on the HRCT findings, the tumours were divided into part-solid ground glass nodules (n = 11) and solid nodules (n = 11). The mean CT attenuation value was 25.7 HU (range, 17–35 HU). All tumours, except 3 tumours pathologically diagnosed as AIS, showed air-containing features. According to the preoperative CT findings, 7 (35%) cases were diagnosed as inflammatory nodules. Of these, 4 cases had lobular-bounded margins, and 3 showed vaguely outlined ground glass shadows. Conclusion: The characteristic HRCT findings of mucinous AIS and MIA were solid or part-solid nodules with air-containing spaces. However, some AIS and MIA nodules showed lobular-bounded margins or marginally vaguely outlined ground glass shadows, and were difficult to differentiate from inflammatory nodules.

  13. Posterior urethral obstruction: Prenatal sonographic findings and clinical outcome in 12 cases

    International Nuclear Information System (INIS)

    Twelve cases of fetal urethral obstruction were reviewed retrospectively. A dilated posterior urethra was identified in eight fetuses (67%) and an enlarged bladder in 11 (92%). Ureterectasis, pyelocalicectasis, increased renal echogenicity, and renal cysts suggest abnormal renal development. Ureterectasis was demonstrated in seven fetuses (58%) and pyelocalicectasis in ten (83%). Renal echogenicity was increased in eight of ten cases (80%) and renal cysts were identified in two cases. Decreased amniotic fluid volume complicated ten pregnancies (83%). There were six live births, but only two neonates survived more than 5 weeks. Pulmonary immaturity contributed to the four postnatal deaths

    The historic, physical, laboratory, and histologic findings for 74 cats with chronic renal disease were reviewed. Most cats were older, and no breed or sex predilection was detected. This most common clinical signs detected by owners were lethargy, anorexia, and weight loss. Dehydration and emaciation were common physical examination findings. Common laboratory findings were nonregenerative anemia, lymphopenia, azotemia, hypercholesterolemia, metabolic acidosis, hyperphosphatemia, and isosthenuria. The most common morphologic diagnosis was chronic tubulointerstitial nephritis of unknown cause.

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

  16. Sonographic findings of the uterus didelphys associated with obstructed hemivagina and ipsilateral renal agenesis: Report of 4 cases

    International Nuclear Information System (INIS)

    The association of uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is rare anomaly. It is caused by failure in the fusion of the caudal portion of the M llerian duct, secondary to Wolffian duct anomaly. We report 4 cases of uterus didelphys with an obstructed hemivagina and ipsilateral renal agenesis. All 4 cases are diagnosed by ultrasonogram, IVU, CT and MRI findings and confirmed by surgery or diagnostic laparoscopy and vaginal examination.

    We report the ultrasonographic and computed tomography (CT) findings of a deep type of penile leiomyosarcoma that helped characterize a penile mass along with a review of the published literature. Leiomyosarcoma of the penis is a very rare disease characterized by a lobulated, expansile, soft tissue mass in CT images, with peripheral rim enhancement and internal homogeneous low density. The ultrasonographic findings revealed a lobulated and heterogeneously hypoechoic solid mass at the distal tip of the penis.

    The os supratalare is quite a rare accessory ossicle of the ankle and the foot. We present imaging findings of a symptomatic os supratalare in a 21-year-old woman with a painful bump of the dorsal aspect on her hind foot. CT and MRI are helpful to distinguish this accessory ossicle from a fracture or an osteochondroma. Knowledge of imaging findings and clinical significances of os supratalare will be helpful for accurate diagnosis and appropriate management.

    A 53-year-old man with a 2-month history of left periorbital swelling was found to have a large solid intraconal mass on CT scan. Orbital ultrasound showed that the lesion had a cavernous pattern of internal reflectivity. Histopathology revealed hyaline-vascular type Castleman disease (CD). This article represents the first reported orbital ultrasound findings in CD. The findings of CT scan and ultrasound may be useful in the preoperative evaluation of orbital hyaline-vascular type CD.

    The main objectives of the present study are to assess the incidence of cerebral venous thrombosis (CVT) presenting as isolated subarachnoid hemorrhage (SAH) and to determine the occurrence of cortical venous thrombosis (CoVT). Among 332 patients with CVT, investigated with the same CT and MR standardized protocol, 33 (10 %) presented with SAH, associated in 11 cases with hemorrhagic infarct or intracerebral hemorrhage. This study is based on 22 cases of CVT presenting as SAH in the absence of hemorrhagic brain lesion. Diagnosis of sinus thrombosis was established on T2* and magnetic resonance venography and that of CoVT on T2* sequence. Diagnostic of SAH was based on fluid-attenuated inversion recovery (FLAIR) sequence. CVT involved lateral sinus in 18 patients, superior sagittal sinus in 16, and straight sinus in 1. Cortical veins were involved in all patients, in continuity with dural sinus thrombosis when present. SAH was circumscribed to few sulci in all cases and mainly localized at the convexity (21 cases). CoVT implied different areas on the same side in four patients and was bilateral in seven. There was no perimesencephalic or basal cisterns hemorrhage. Cortical swelling was present in 12 cases, associated with localized edema. All patients except one had a favorable outcome. This report shows that the incidence of CVT presenting as isolated SAH is evaluated to 6.4 % and that SAH is, in all cases, in the vicinity of CoVT and when dural thrombosis is present in continuity with it.

    Objective. To assess the utility of magnetic resonance imaging (MRI) in the investigation of palpable masses in the hand or wrist.< rate at head-abs-p1.lf>Design and patients. We retrospectively reviewed the MRI examinations and case records of 134 patients referred because of a palpable mass in the hand or wrist. MRI was performed on a 1.0 T magnet using an extremity coil. Intravenous gadolinium-DTPA was injected when considered appropriate.< rate at head-abs-p1.lf>Results and conclusions. MRI demonstrated the cause of the palpable mass in 126 cases (94.02%). Soft tissue neoplasms were found in 34 cases (25.37%). The majority were benign and included giant cell tumours of tendon sheath, lipomas and hemangiomas and had a characteristic appearance. There were three malignant tumours (myxoid liposarcoma, malignant fibroushistiocytoma and rhabdomyosarcoma). Ganglia were found in 36 cases (26.86%) and non-tumour tendon pathology in 31 cases (23.13%). Less common causes included articular diseases (5.97%) and anatomical variants (4.47%). No focal lesion was present in 8 cases (5.97%). In conclusion, MRI is an accurate diagnostic technique in patients who present with a palpable mass of the hand and wrist. (orig.)

  8. Idiopathic muscular hypertrophy of the esophagus. Postmortem incidental finding in six cases and review of the literature.

    Six cases of idiopathic muscular hypertrophy of the esophagus were found at autopsy in a relatively short period of time. As has been the experience in previously reported cases, our finding was incidental at the autopsy in all of the cases. In only one of our patients were there relevant symptoms and radiographic changes that could be attributed to the disease. How often patients with muscular hypertrophy of the esophagus have the clinical syndrome of diffuse esophageal spasm remains unclear. It is therefore evident that only by awareness of this entity can studies of esophageal funtion, x-ray films, and appropriate treatment prevent serious morbidity and occasional mortality from the disease.

    Lysinuric protein intolerance is an autosomal recessive disease caused by defective transport of cationic amino acids. Of the 38 lysinuric protein intolerance patients diagnosed in Finland since 1965, four pediatric patients have died. We describe the clinical courses and autopsy findings for these patients. All patients developed acute respiratory insufficiency. In addition to pulmonary hemorrhages, three of the patients had pulmonary alveolar proteinosis and one had cholesterol granulomas. Three patients had a clinically obvious renal insufficiency, but all four showed histologic signs of immune complex-mediated glomerulonephritis. The patients also developed hepatic insufficiency with fatty degeneration or cirrhosis. All patients showed anemia, thrombocytopenia, and a severe bleeding tendency. The bone marrow of three patients was hypercellular, but the amount of megakaryocytes was decreased in two cases. Amyloid was present in the lymph nodes and the spleen. Bone specimens showed osteoporosis. We conclude that pediatric patients with lysinuric protein intolerance are predisposed to develop pulmonary alveolar proteinosis and glomerulonephritis. They are also at risk of protein malnutrition in the active growth phase, probably due to higher requirements for total nitrogen and amino acids. PMID:8163273

    females 5 years later. Younger adolescents appear to be especially influenced by their same-sex parent. These findings suggest that encouragement may be more influential than parental concern for fitness on adolescents' physical activity habits. Further research is needed to determine how parents can help adolescents decrease sedentary behavior time.

    The research compound 25I-NBOMe, also known as CIMBI-5 or INBMeO, was created in academic laboratories as a potent serotonin 2A receptor agonist. Because of its high affinity and ambiguous legal status, recreational drug enthusiasts have used this compound as a powerful alternative to other hallucinogenic drugs such as lysergic acid diethylamide. We report 2 deaths after 25I-NBOMe ingestion by decedents who attended separate "rave" parties. The first case involved a 21-year-old male who admitted taking "acid" to his friend. A sudden violent rage caused him to flail about, and he subsequently became unresponsive. The postmortem examination revealed numerous external injuries that were consistent with physical aggression. The second case involved a 15-year-old female who was socializing outside a rave party, became ill, and rapidly deteriorated as her friend transported her to the hospital. The postmortem assessment was similar to the first case in that external contusions featured prominently. Comprehensive toxicology screens in both cases revealed only evidence of marijuana use. A deeper analysis using time-of-flight mass spectrometry revealed the presence of 25I-NBOMe, which was further confirmed by tandem-mass spectrometry. The behavior and injuries in these cases reveal a consistent pattern preceding fatal 25I-NBOMe toxicity.

  12. Clinical and radiological findings in a case of non-syndromic oligodontia

    International Nuclear Information System (INIS)

    A case of congenital absence of eleven dental pieces without association to syndromes is presented. An integral clinical examination of the patient's dental pieces has determined a case of oligodontia. Congenital absence of all permanent teeth described in the clinical examination are presented by orthopantomography radiography. Impressions with irreversible hydrocolloid are realized to complete the diagnostic. The case described of oligodontia has developed without presenting relation to some syndrome as Down syndrome or ectodermal dysplasia. Genes have played a very important role in the etiology of dental anomalies, according to the existing evidence. Mutation has been identified as the cause of dental defects in some of the genes in humans. The maxillary teeth developed in the marginal areas of the dental lamina have pretended to be the dental pieces more susceptible to be without form

    We are reporting 3 cases of pediatric endobronchial tumors presented with recurrent pneumonia. The median age of patients, at time of presentation, was 10.6 years. All patients presented with recurrent pneumonia with a mean time to occurrence, after onset of symptoms, of 14 mo. Bronchoscopy was early performed as part of diagnostic work-up and it revealed an endobronchial mass in every case. Complete surgical resection was performed in all cases, with lung preservation in two of them. Neither post-operative chemotherapy nor radiotherapy was required. The mean duration of follow-up was 7 years and all patients are still alive and disease-free. Recurrent pneumonia, in pediatrics, should raise the suspicion of an obstructing lesion, congenital malformation or systemic disease. A systematic approach is useful for organize the clinicians initial workup. Prompt diagnosis allows parenchymal-sparing surgery, which offers the best chance of cure and reduces clinical and functional complications in these patients. PMID:26015878

    Sonographic findings correlated with necropsy findings in 8 of 9 horses in which the cranial portion of the mediastinum was evaluated by use of both methods. Cranial mediastinal masses were imaged as multilobular and homogeneously hypoechoic; a complex echogenic pattern was observed with necrosis within the mass. Pleural effusion was a common finding in horses with mediastinal lymphosarcoma. Cytologic evaluation of pleural fluid samples was useful in diagnosis of lymphosarcoma in 10 of 12 horses that had thoracentesis. Sonographic examination of the thorax and cranial portion of the mediastinum can aid in the diagnosis of mediastinal lymphosarcoma in horses. Such examination should be performed in horses with clinical signs of cranial vena cava obstruction in which pleural effusion is detected, or when thoracic lymphosarcoma is suspected. PMID:7698925

    This is a retrospective analysis of electroencephalograms (EEG) and computed tomograms (CT) obtained from 99 Japanese patients with herpes simplex encephalitis (HSE). Abnormal findings of EEG were seen in 89 patients (99 %). Focal abnormality, which was frequently detected in the first EEG recording, was seen in 68 patients (76 %). Periodic synchronous discharge was observed in 25 patients (28 %). There were abnormal findings on CT in 88 patients (81 %). Low and high density areas were seen in 64 patients (73 %) and 26 patients (37 %), respectively, with the most frequent site being the temporal lobe. Mass effect was demonstrated in 33 patients (37 %). Electroencephalography detected the abnormal findings earlier than CT during the early stage of HSE in many instances. There was concordance between EEG and CT in the detection of HSE lesions in 45 patients (58 %). (Namekawa, K.).

    We wanted to describe the findings of simple pulmonary eosinophilia with using 18 fluorodeoxyglucose (FDG) positron emission tomography (PET). We analysed the findings of 14 patients who underwent thoracic computed tomography (CT) and PET, and then they were subsequently proven to have simple pulmonary eosinophilia. PET studies were performed in four patients with malignancy to evaluate for cancer metastasis, and PET scans were also done in 10 healthy subjects who underwent volunteer cancer screening. The PET scans were evaluated by using the maximum standardized uptake values (SUVs). The subjects' CT findings also were reviewed and correlated with the PET findings. A total of 42 nodules were detected on the CT scans. There were single nodules in three patients and multiple nodules in 11 patients (mean number of nodules: 3, range: 1-10, mean diameter: 9.5 mm {+-} 4.7). Twelve of 42 (28.6%) nodules showed FDG uptake and their mean maximum SUV was 2.5 {+-} 1.6 (range: 0.6-5.3). Five of six solid nodules showed FDG uptake (2.2 {+-} 1.1, range: 0.9-3.6), six of 11 semisolid nodules showed FDG uptake (3.1 {+-} 1.8, range: 0.6-5.3) and one of 25 pure ground-glass opacity nodule showed a maximum SUV of 0.8. The maximum SUVs of seven nodules in five patients were greater than 2.5. The maximum SUVs were significantly different according to the nodule types ({rho} < 0.001). Simple pulmonary eosinophilia commonly causes an increase in FDG uptake. Therefore, correlation of the PET findings with the CT findings or the peripheral eosinophil counts can help physicians arrive at the correct diagnosis of simple pulmonary eosinophilia.

  17. MR and CT findings in a case of hibernoma of the thigh extending into the pelvis

    International Nuclear Information System (INIS)

    Review of the literature shows no report of hibernoma of the thigh extending into the pelvis. Herein we report a case of hibernoma which appeared on CT and MR as a well-defined pelvic mass with contrast enhancement extending through the obturator foramen into the thigh. Fat was demonstrated by CT, whereas MR, using multiplanar sections, better analyzes the extension of the mass. This case demonstrates that hibernoma as liposarcoma can extend through the obturator foramen. However, no definite diagnosis could be made by CT or MR and the tumor must be considered as a ''potential'' malignant liposarcoma. (orig.)

    2011-01-01

    Congenital left ventricular diverticulum is a very rare cardiac abnormality and it is not completely understood about its etiology, clinical manifestation, diagnosis, treatment and prognosis. This article presents a case of large congenital diverticulum of the left ventricle. The clinical manifestation included paroxysmal supraventricular tachycardia. The diagnosis was made by chest fluoroscopy observation and confirmed by 64-slice CT-angiography. The arrhythmia alleviated instead of antiarrhythmic drugs but by radiofrequency catheter ablation. Due to the rapid growth of the diverticulum, the patient underwent surgical resection finally. Owing to the fatal risks, clinicians should improve the understanding of this disease by deeply studying more cases, in order to standardize the treatment.

    Polyacrylamide gel has been widely used for soft tissue contouring for more than 30 years and has been used for breast mammoplasty augmentation in China since 1997. As Korea is close to China, Korean clinicians often encounter the patients who have undergone polyacrylamide gel augmentation mammoplasty. Therefore, radiologists should know the ultrasonographic and mammographic findings and the complications of polyacrylamide gel augmented mammoplasty: this can be helpful in the diagnosis and management of those patients. We report the characteristic radiological findings of a patient who had undergone mammoplasty augmentation with polyacrylamide gel

    Wilson-Mikity syndrome (WMS), an uncommon cause of respiratory distress presenting after birth, is radiologically characterised by varying degrees of interstitial thickening and bilateral cyst-like foci of hyperinflation. Aetiology and pathogenesis are still unknown. There are few reports of WMS in the paediatric literature and none describing the features and value of high-resolution CT. The purpose of this report is to describe the radiographic findings and high-resolution CT appearance of WMS and to correlate them with the histopathological findings. (orig.) With 3 figs., 6 refs.

    Objectives: To determine whether imaging findings can be used to differentiate between impact and non-impact head trauma in a group of fatal and non-fatal abusive head trauma (AHT) victims. Methods: We included all AHT cases in the Netherlands in the period 2005–2012 for which a forensic report was written for a court of law, and for which imaging was available for reassessment. Neuroradiological and musculoskeletal findings were scored by an experienced paediatric radiologist. Results: We identified 124 AHT cases; data for 104 cases (84%) were available for radiological reassessment. The AHT victims with a skull fracture had fewer hypoxic ischaemic injuries than AHT victims without a skull fracture (p = 0.03), but the relative difference was small (33% vs. 57%). There were no significant differences in neuroradiological and musculoskeletal findings between impact and non-impact head trauma cases if the distinction between impact and non-impact head trauma was based on visible head injuries, as determined by clinical examination, as well as on the presence of skull fractures. Conclusions: Neuroradiological and skeletal findings cannot discriminate between impact and non-impact head trauma in abusive head trauma victims.

  11. Uterus Didelphys with Obstructed Hemivagina and Ipsilateral Renal Agenesis: The Radiologic Findings of Five Cases

    International Nuclear Information System (INIS)

    To evaluate the imaging findings of uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis. From March 2003 to December 2008, five patients with uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis were evaluated as part of this study. We retrospectively reviewed the CT, ultrasound, and MRI findings as well as the medical records of each patient. The patients initially underwent an imaging study for abdominal pain (n=3), recurrent vaginal bleeding (n=1), and prenatal evaluation (n=1). Of the five patients that underwent US, four had hematocolpos and two of them had hematometra. Moreover, three patients underwent a CT examination. The MR examination of four patients revealed hematocolpos (n=3), hematometra (n=1), and a tubular structure resembling an ectopic ureter (n=2). The gynecologic examination of a patient without hematocolpos revealed a pinpoint hole in the vaginal septum. Two of four patients with hematocolpos underwent a vaginal septectomy, which resulted in an improvement of the symptoms. The most common finding of patients with uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis is vaginal fluid collection. Hematometra is not a consistent finding and can be transient according to the menstrual cycle. MR is the most useful imaging modality for the diagnosis of an ectopic ureter

    2011-03-15

    Neurolymphomatosis is a rare manifestation of malignant lymphoma. A 74 year old man, in complete remission from diffuse large B cell lymphoma, presented with a loss of pain and temperature sensation in the left hemiface and left upper extremity, and motor weakness in the left upper and both lower extremities. Cerebrospinal fluid analysis and brain magnetic resonance imaging (MRI) findings were negative. Combined fluorine 18 fluorodeoxyglucose positron emission tomography/computed tomography (FDG PET/CT) revealed multiple linear hypermetabolic lesions along the mandibular branch of the left trigeminal nerve, left brachial plexus, right adrenal gland, right femoral nerve, and both sciatic nerves, which corresponded to the patient's complex neurologic symptoms. C spine and pelvic MRI revealed diffuse thickening with enhancement in the left sciatic nerve, but negative findings for other sites identified by FDG PET/CT. These findings for other sites identified by FDG PET/CT. These findings suggest that FDG PET/CT can detect peripheral nerve infiltration by malignant lymphoma earlier than MRI. Thus, if a patient with a history of lymphoma presents with neurologic symptoms, FDG PET/CT should be performed to evaluate neurolymphomatosis.

    This study concerns about brain electrical activity during auditory stimulation in 2 aphasic patients, one with classical (left hemisphere lesion) and another with cross aphasia (right hemisphere lesion). Both cases were submitted to dichotic listening test (consonant-vowel-consonant task) and music audition (gregorian chant), during brain mapping examination. We found, in both cases, a great proportion in delta frequency and power in non-lesional hemisphere during dichotic and musical stimulation. Besides, increasing in frequency of alpha activity was observed only in the non-lesional hemisphere restricted to temporal lobe region. Such findings suggest an interesting field of research about measurements of neurophysiological correlates of auditory stimulation and brain electrical activity in aphasia. PMID:7575214

    Primary mucinous cystadenocarcinoma (MCA) of the breast is a rare but pathologically distinct breast tumor. There have been some case reports on primary MCA of the breast; however, they have all focused on pathologic findings. Here, we report the radiologic findings of two cases of MCA along with a review of the literature. Breast MCA shows a circumscribed mass with some calcifications on mammography, an intracystic solid mass without increased vascularity or a vascular stalk on ultrasound, and a heterogeneously enhancing mass within a rim-enhancing cyst with intermediate signal intensity on T2-weighted magnetic resonance imaging. These radiologic findings and the presence of mucin in the percutaneous biopsy specimen should suggest the possibility of MCA in the differential diagnosis of a breast tumor. PMID:27721884

    Full Text Available Abstract Background Population impact measures (PIMs have been developed as tools to help policy-makers with locally relevant decisions over health risks and benefits. This involves estimating and prioritising potential benefits of interventions in specific populations. Using tuberculosis (TB in India as an example, we examined the population impact of two interventions: direct observation of therapy and increasing case-finding. Methods PIMs were calculated using published literature and national data for India, and applied to a notional population of 100 000 people. Data included the incidence or prevalence of smear-positive TB and the relative risk reduction from increasing case finding and the use of direct observation of therapy (applied to the baseline risks over the next year, and the incremental proportion of the population eligible for the proposed interventions. Results In a population of 100 000 people in India, the directly observed component of the Directly Observed Treatment, Short-course (DOTS programme may prevent 0.188 deaths from TB in the next year compared with 1.79 deaths by increasing TB case finding. The costs of direct observation are (in international dollars I$5960 and of case finding are I$4839 or I$31702 and I$2703 per life saved respectively. Conclusion Increasing case-finding for TB will save nearly 10 times more lives than will the use of the directly observed component of DOTS in India, at a smaller cost per life saved. The demonstration of the population impact, using simple and explicit numbers, may be of value to policy-makers as they prioritise interventions for their populations.

    We report two cases, one of acute cerebral swelling and the other with a major stroke, whose MRI has shown very interesting findings. Case 1, a 32-year-old male, was admitted to our service because of a lowering of his consciousness immediately after a head injury. On admission, the patient was semicomatous (E/sub 1/M/sub 2/V/sub 1/, with anisocoria (R > L). His plain skull X-ray was normal. A CT scan, however, demonstrated right isodensity hemispheric swelling associated with a subarachnoid hemorrhage in the right Sylvian fissure. A right carotid angiogram showed no vascular disorders. MR imaging of the spin density demonstrated a hyperintensitive thickening of the gray matter in the whole right hemisphere. Case 2, a 58-year-old female, was admitted because of a sudden onset of loss of consciousness, with right hemiparesis and dysarthria. On admission, her consciousness was semicomatous (E/sub 1/M/sub 3/V/sub 1/), and it deteriorated to a deep coma 1 hour later. A CT scan demonstrated a diffuse left hemispheric low density, with a finding of hemorrhagic infarction in the basal ganglia. MR imaging of the spin density showed a hyperintensitive thickening of the gray matter resembling that of Case 1. The findings of the spin-echo images of our two cases showed a hyperintensitive thickening of the gray matter in both. The hyperintensity and thickening of the gray matter apparently indicated a sort of hyperemia and brain edema. These findings led us to suspect that the hyperemia associated with acute cerebral swelling and ischemic brain edema of our two cases originated in the gray matter, although it has been considered that the pathogenesis of acute cerebral swelling is not known and that brain edema, especially vasogenic edema, will mostly develop in the white matter rather than in the gray matter.

    Accidental aspiration of diesel can cause consolidation, atelectasis, and abscess formation. Aspiration of diesel usually results into pneumonitis, which resolves completely within 5-7 days of treatment. Diesel aspiration resulting in bilateral pneumonia and death is rare and is scarcely documented in literature. Finding of lipoid cells in lung autopsy specimen is one of the important features of hydrocarbon aspiration. Unfortunately this important finding is not mentioned in most of the toxicology textbooks. Hence, we are reporting this case. PMID:25948973

    2015-12-01

    Full Text Available The calcifying cystic odontogenic tumor (CCOT is a rare cystic odontogenic neoplasm frequently found in association with odontome. This report documents a case of CCOT associated with an odontome arising in the anterior maxilla in a 28-year-old man. Conventional radiographs showed internal calcification within the lesion but were unable to visualize its relation with the adjacent structures and its accurate extent. In this case cone beam computed tomography (CBCT could accurately reveal the extent and the internal structure of the lesion which aided the presumptive diagnosis of the lesion as CCOT. This advanced imaging technique proved to be extremely useful in the radiographic assessment and management of this neoplasm of the maxilla.

    Full Text Available Ureter duplication is the most common congenital anomaly of the urinary system. Ureteral duplication varies from a bifid pelvis to completely separate ureters. The reported incidence varies from 0.8% in an autopsy series, to 40% in a pyelography review, and displays a wide spectrum of imaging findings . The unilateral form occurs about 6 times more commonly than the bilateral form, with the left and right sides being almost equally involved. A 37 year old male with no previous history for stone disease presented to the urology department with right sided colicky pain for three hours. Ultrasonography and Computurized Tomography (CT were performed. We demonstrated radiologic findings of distal ureter with partially double lumen. According to our knowledge, it has not been reported in the literature previously.

    A nonrecurrent inferior laryngeal nerve (NRILN) is found more frequently on the right side than on the left, and it is closely associated with an aberrant right subclavian artery. The presence of the aberrant right subclavian artery on preoperative computed tomography (CT) scan suggests NRILN; however, different types of branching locations and pathways exist. Here, we report three NRILN cases with different pathways where the vagus nerve arises more medial than usual and a review of the literature. Case 1: A 30-year-old Japanese female presented with papillary thyroid carcinoma. Preoperative CT scan revealed an aberrant right subclavian artery, and an operation was performed under suspicion of NRILN. During the operation, the vagus nerve was found to arise more medially than usual and two NRILNs originated from it at the level of the cricoid cartilage and at a more caudal position; the two NRILNs were preserved. Case 2: A 33-year-old Japanese female with a thyroid nodule of increased size underwent surgery. Preoperative CT scan revealed an aberrant right subclavian artery, which suggested NRILN. During the operation, the vagus nerve was identified to run more medially than usual and NRILN was found to originate at the level of the cricoid cartilage; NRILN was preserved. Case 3: A 78-year-old Japanese female underwent an operation with a diagnosis of papillary thyroid carcinoma. Preoperative CT scan showed an aberrant right subclavian artery. During the operation, NRILN was found to originate from the vagus nerve at the level of the lower pole of the thyroid gland, and the vagus nerve ran medial to the common carotid artery at the caudal level.

    Sinistral portal hypertension occurs when a pathological process causes occlusion of the splenic vein. The resultant elevated splenic bed venous pressure causes formation of gastric varices which can lead to hematemesis as a common presentation for this disease process. We present a case of sinistral portal hypertension in a patient with acute hematemesis as the primary presentation. Despite the challenging diagnosis process, the patient underwent splenectomy and was managed appropriately according to previously published literature. PMID:22470692

    Gliomatosis cerebri is a rare primary diffuse cerebral malignity. It is characterized by diffuse proliferation of neoplastic glial cells that involve one or more cerebral lobes. For definitive diagnosis histopathological examination is required. Advanced magnetic resonance imaging techniques are very useful in pretreatment diagnosis-staging and post-treatment follow-up. In this report a patient with gliomatozis cerebri was presented associated with the findings of magnetic resonance images, d...

    Pyotraumatic dermatitis (hot spot) is a common clinical syndrome in dogs but there are few prospective scientific studies related to it. The aim of this study was to investigate correlations among clinical pyotraumatic dermatitis, histopathology of the lesions and possible predisposing causes. The relationship of these with breed, age, sex and location of lesion was assessed statistically. A clinical diagnosis of acute pyotraumatic dermatitis was made in 44 privately owned dogs. Males exceeded females (P = 0.0348) and lesions were more common in dogs aged 4 years or less (P otitis externa was recorded and the study was conducted in an area without endemic fleas. Fourteen breeds were represented of which Rottweiler, German shepherd dog and golden retriever were most common. There was no significant seasonal incidence and no correlation among site of lesion and cause, time of year, age or sex. Histopathologically, the dogs could be separated into four patterns by the presence or absence of eosinophils and/or folliculitis. Eosinophils have not previously been recorded in pyotraumatic dermatitis but were seen in 29 cases. Acute folliculitis was seen in 20 cases. However, no correlation was seen among age, sex, breed, underlying cause or site of lesion and histopathology. Twenty-seven cases were cultured for bacteria of which 25 grew Staphylococcus intermedius and two were negative.

  4. Focal retrograde amnesia: voxel-based morphometry findings in a case without MRI lesions.

    Directory of Open Access Journals (Sweden)

    Bernhard Sehm

    Full Text Available Focal retrograde amnesia (FRA is a rare neurocognitive disorder presenting with an isolated loss of retrograde memory. In the absence of detectable brain lesions, a differentiation of FRA from psychogenic causes is difficult. Here we report a case study of persisting FRA after an epileptic seizure. A thorough neuropsychological assessment confirmed severe retrograde memory deficits while anterograde memory abilities were completely normal. Neurological and psychiatric examination were unremarkable and high-resolution MRI showed no neuroradiologically apparent lesion. However, voxel-based morphometry (VBM-comparing the MRI to an education-, age-and sex-matched control group (n = 20 disclosed distinct gray matter decreases in left temporopolar cortex and a region between right posterior parahippocampal and lingual cortex. Although the results of VBM-based comparisons between a single case and a healthy control group are generally susceptible to differences unrelated to the specific symptoms of the case, we believe that our data suggest a causal role of the cortical areas detected since the retrograde memory deficit is the preeminent neuropsychological difference between patient and controls. This was paralleled by grey matter differences in central nodes of the retrograde memory network. We therefore suggest that these subtle alterations represent structural correlates of the focal retrograde amnesia in our patient. Beyond the implications for the diagnosis and etiology of FRA, our results advocate the use of VBM in conditions that do not show abnormalities in clinical radiological assessment, but show distinct neuropsychological deficits.

    In total, participants from 14 countries, representing 19 organisations, actively participated in the model application/inter-comparison activities of the IAEA's EMRAS II programme Biota Modelling Group. A range of models/approaches were used by participants (e.g. the ERICA Tool, RESRAD-BIOTA, the ICRP Framework). The agreed objectives of the group were: 'To improve Member State's capabilities for protection of the environment by comparing and validating models being used, or developed, for biota dose assessment (that may be used) as part of the regulatory process of licensing and compliance monitoring of authorised releases of radionuclides.' The activities of the group, the findings of which will be described, included: - An assessment of the predicted unweighted absorbed dose rates for 74 radionuclides estimated by 10 approaches for five of the ICRPs Reference Animal and Plant geometries assuming 1 Bq per unit organism or media. - Modelling the effect of heterogeneous distributions of radionuclides in sediment profiles on the estimated exposure of organisms. - Model prediction - field data comparisons for freshwater ecosystems in a uranium mining area and a number of wetland environments. - An evaluation of the application of available models to a scenario considering radioactive waste buried in shallow trenches. - Estimating the contribution of {sup 235}U to dose rates in freshwater environments. - Evaluation of the factors contributing to variation in modelling results. The work of the group continues within the framework of the IAEA's MODARIA programme, which was initiated in 2012. The work plan of the MODARIA working group has largely been defined by the findings of the previous EMRAS programme. On-going activities of the working group, which will be described, include the development of a database of dynamic parameters for wildlife dose assessment and exercises involving modelling the exposure of organisms in the marine coastal

  7. Case Report of Fire Eater’s Pneumonia in Adolescent Female Patient – Evolution of Radiologic Findings

    International Nuclear Information System (INIS)

    We present a case of a 16-year-old girl with fire-eater’s pneumonia (hydrocarbon pneumonitis). The goal of this report was to assess evolution of radiological findings. The reported case was unique because that was the first completely described case of fire-eater’s pneumonia reported in an under-aged person. Moreover, this disease is very rare even in adults and only a few scientific reports can be found, mostly because of a small occupational group. The aim of this report was to show that the problem of fire-eater’s pneumonia can occur in under-aged patients and should be taken into consideration in case of severe pneumonia. Another objective was to point out that chest radiograph is not sufficient to depict the evolution of radiological manifestations

  8. Prompt Gamma Activation Analysis of the Nyírlugos obsidian core depot find

    2014-03-01

    Full Text Available The Nyírlugos obsidian core depot find is one of the most important lithic assemblages in the collection of the Hungarian National Museum (HNM. The original set comprised 12 giant obsidian cores, of which 11 are currently on the permanent archaeological exhibition of the HNM. One of the cores is known to be inDebrecen. The first publication attributed the hoard, on the strength of giant (flint blades known from the Early and Middle Copper Age Tiszapolgár and Bodrogkeresztúr cultures, to the Copper Age. In the light of recent finds it is more likely to belong to the Middle Neolithic period. The source area was defined as Tokaj Mts., about100 kmto the NW from Nyírlugos. The size and beauty of the exceptional pieces exclude any invasive analysis. Using Prompt Gamma Activation Analysis (PGAA, we can measure major chemical components and some key trace elements of stone artefacts with adequate accuracy to successfully determine provenance of obsidian. Recent methodological development also facilitated the study of relatively large objects like the Nyírlugos cores. The cores were individually measured by PGAA. The results show that the cores originate from the Carpathian 1 sources, most probably the Viničky variety (C1b. The study of the hoard as a batch is an important contribution to the assessment of prehistoric trade and allows us to reconsider the so-called Carpathian, especially Carpathian 1 (Slovakian sources.

  9. Clinicopathological findings in a case series of extrathoracic solitary fibrous tumors of soft tissues

    2006-07-01

    Full Text Available Abstract Background Solitary fibrous tumors (SFT represent a rare entity of soft tissue tumors. Previously considered being of serosal origin and solely limited to the pleural cavity the tumor has been described in other locations, most particularly the head and neck. Extrathoracic SFT in the soft tissues of the trunk and the extremities are very rare. Nine cases of this rare tumor entity are described in the course of this article with respect to clinicopathological data, follow-up and treatment results. Methods Data were obtained from patients' records, phone calls to the patients' general practitioners, and clinical follow-up examination, including chest X-ray, abdominal ultrasound, and MRI or computed tomography. Results There were 6 females and 3 males, whose age at time of diagnosis ranged from 32 to 92 years (mean: 62.2 years. The documented tumors' size was 4.5 to 10 cm (mean: 7 cm. All tumors were located in deep soft tissues, 3 of them epifascial, 2 subfascial, 4 intramuscular. Four tumors were found at the extremities, one each at the flank, in the neck, at the shoulder, in the gluteal region, and in the deep groin. Two out of 9 cases were diagnosed as atypical or malignant variant of ESFT. Complete resection was performed in all cases. Follow-up time ranged from 1 to 71 months. One of the above.mentioned patients with atypical ESFT suffered from local relapse and metastatic disease; the remaining 8 patients were free of disease. Conclusion ESFT usually behave as benign soft tissue tumors, although malignant variants with more aggressive local behaviour (local relapse and metastasis may occur. The risk of local recurrence and metastasis correlates to tumor size and histological status of surgical resection margins and may reach up to 10% even in so-called "benign" tumors. Tumor specimens should be evaluated by experienced soft tissue pathologists. The treatment of choice is complete resection followed by extended follow

  10. Clinical, radiographic, and histological findings of florid cemento-osseous dysplasia: a case report

    International Nuclear Information System (INIS)

    Cemento-osseous dysplasias are a group of disorders known to originate from periodontal ligament tissue and involve, essentially, the same pathological process. They are usually classified into three main groups: periapical, florid, and focal cemental dysplasias depending on their extent and radiographic appearances. Radiographically, florid cementoosseous dysplasia (FCOD) appears as dense, lobulated masses, often symmetrically located in various regions of the jaws. The best management for the asymptomatic FCOD patient consists of regular recall examinations with prophylaxis. The management of the symptomatic patient is more difficult. A case of FCOD occurring in a 52-year-old edentulous Korean female is reported which is rare with regard to race and sex.

    Full Text Available Sleep-related bruxism may present with headache. However, in clinical practice it may be difficult to differentiate from other causes of headache, especially in subjects with substance abuse. We are presenting a case of sleep-related bruxism that presented with headache and sleep-related symptoms in the presence of substance abuse. Polysomnography was used to ascertain cause of headache. How the other possible causes of headache ruled out is also discussed in report. In short, Sleep-related bruxism can cause headache that is worse in the morning. It is associated with poor quality sleep.

    Rostering is an important process to enable efficient, effective and safe delivery of health care, and one which receives little attention. The work outlined in this case study demonstrates that the analysis of rostering processes from a range of perspectives including the organisation, staff and the roster manager can identify significant opportunities for improvement. Roster governance is not universally applied, nor understood, which can result in dissonant expectations between managers and staff and a lack of transparency in how and why decisions about rostering are made. Redesigning roster processes can promote more effective governance and improve organisational efficiency. PMID:25844568

    Fifteen patients with Sjoegren's syndrome without clinical evidence of central nervous system disease were studied by MRI. Signal abnormalities were observed in 9 (60%). They were always visible on T2-weighted images as small punctale areas of high signal in the basal ganglia and the white mater of the cerebral hemispheres. Abnormalities were less frequently seen on T1-weighted images. Enlargement of cerebral sulci was observed in 6 cases. The specificity and significance of these abnormalities are discussed. (orig.)

  15. Prenatal MR findings in a case of aneurysm of the vein of Galen

    International Nuclear Information System (INIS)

    We describe a case of aneurysm of the vein of Galen (AVG), which was diagnosed by intrauterine US, MRI and MRA. The baby girl was born at 35 weeks' gestation. She had severe clinical symptoms at birth and died at 29 h of age from intractable congestive heart failure. Intrauterine US detected an intracranial aneurysm and cardiomegaly due to excessive arteriovenous shunting. Intrauterine MRI (SSFSE) confirmed the diagnosis of AVG, and intrauterine MRA (2D-TOF) successfully demonstrated the anatomical structure of the AVG. MRA may be a useful additional sequence to evaluate AVG, and 2D-TOF is thought to be an appropriate technique for scanning fetal AVG. (orig.)

    We describe an unusual case of cysticercosis in soft tissue. On US, a well-defined oval shaped cystic lesion with an inner central hyperechoic portion was noted. This portion showed high signal intensity on T1-weighted images and equivocal enhancement. On MRI, other portions of the lesion showed their cystic nature. Pathologic examination confirmed the presence of cysticercosis and, in particular, the central portion was found to be a mural nodule with scolex. Cysticercosis in the soft tissue and musculature of patients from endemic areas should thus be considered in the differential diagnosis of an incidental mass, especially when this is cystic and has an inner central nodule

    Primary renal angiosarcoma is a very rare malignant mesenchymal tumor. CT shows a well-margined enhancing mass with hemorrhage, perirenal hematoma and renal vein thrombosis in the lower pole of the right kidney. MRI shows heterogeneous low- and high-signal intensities of the mass on T1- and T2-weighted images, as well as a relatively homogeneous enhancement on contrast enhanced T1-weighted images. We report here on a rare case of primary renal angiosarcoma with spontaneous rupture and venous thrombosis.

    Here, we report psychotic symptoms together with a right cerebellopontine-angle lesion. A37-year-old female patient presented with a trigeminal Schwannoma occupying the right cerebellopontine angle. Her psychotic symptoms included auditory hallucinations and delusions of persecution. T1- and T2-weighted images on magnetic resonance imaging (MRI) revealed hyperintense and hypointense areas in the right cerebellopontine angle, respectively. The clinical and neuroimaging reviews in this case suggest that sudden onset of psychotic symptoms at a mature age may be associated with a right cerebellopontine-angle lesion and that MRI should be used to evaluate possible organic bases in patients that present with psychosis.

    We present a case of a subdural osteoma. A 29-year-old female presented with a 3-year history of headaches. Computed tomography scan revealed a homogeneous high-density lesion isolated from the inner table of the frontal bone (a lucent dural line) in the right frontal convexity. Magnetic resonance imaging revealed an extra-axial lesion with a broad base without dural tail sign and punctate enhancement pattern characteristic of abundant adipose tissue. Upon surgical excision, we found a hard bony mass clearly demarcated from the dura. The mass displayed characteristics of an osteoma upon histological examination. The symptom was relieved after operation. PMID:27195262

    The so-called superior-Cava Syndrome is caused by obstructions by centrally localized tumors by thrombosis or by inflammations of the mediastinum. In cases of tumorous infiltration a graft can be inserted. The different phenomena of thrombosis caused by nutritial catheters and pace makers are of clinical importance. Acute thrombosis of the brachio-cervical veins and the Vena Cava can be treated successfully by means of thrombolysis. Besides CT bilateral brachial phlebography communicates optimal information concerning localization of vascular obstruction and collateral circuits.

    Malignant fibrous histiocytoma (MFH) is the most common soft tissue malignancy in adults. The Ga-67 citrate scan findings of an extremity-located MFH, the most common location of this neoplasm, have never been published in English language journals to the best of the authors' knowledge. Ga-67 citrate and Tc-99m MDP scans of the thigh mass accurately depicted the tumor's local extent, including the presence of central ischemic necrosis within the tumor, and the absence of adjacent osseous involvement and distant metastases, as correlated with computed tomography, angiography, and pathologic examinations.

    Replacement lipomatosis of the kidney is the result of severe atrophy of the renal parenchyma often caused by chronic calculus disease with secondary marked benign proliferation of fibrofatty tissue replacing atrophied renal parenchyma. Different radiological modalities have been used to illustrate this entity, with magnetic resonance imaging, ultrasound, intravenous pyelogram, and computed tomography (CT) used most frequently. We report multidedector CT (MDCT) findings of replacement lipomatosis in a 50-year-old woman. We think that it accurately provides a complete one-step diagnostic workup and appropriate pre-surgical planning for patients for whom there is a suspicion of replacement lipomatosis.

    Most anomalies of intestinal rotation are detected during the postneonatal period. In adults, the diagnosis and treatment of patients with a congenital anomaly of the midgut can be difficult because of their extremely rarity. Based on embryology, anomalies of intestinal rotation can be divided into non-rotation, reversed rotation and malrotation. Reversed rotation of the midgut is the rarest of all anomalies of intestinal rotation. Although this anomaly is rare, it can be diagnosed by a detailed knowledge of embryology and anatomy. We report three adult patients with reversed intestinal rotation and review the embryology, clinical presentation and radiographic findings of this disorder

Follow-up images at seven months showed a slight increase in tumor size, which could be partly explained by intratumoral hemorrhage on pathologic examination. Although rare, bile duct adenoma should be considered as a differential diagnosis of a small hypervascular tumor located in the periphery of liver. Focal cystic change and intratumoral hemorrhage may occur

    In this work the authors report two cases of bronchogenic cyst. The first one, in a 69-year-old female patient, with thoracic pain and dyspnea. At the chest X-ray, a mass in the superior mediastinum was observed. Computed tomography of the thorax showed a cystic expansible formation without impregnation by the contrast agent. The patient was referred to thoracic surgery, where she had resected theexpansible formation, that presented histological characteristics of bronchogenic cyst. The other case, in a 50-year-old female patient, that presented symptoms of malaise, retrosternal pain, dry cough, dyspnea and hemoptysis. The chest X-ray evidenced mass in the posterior mediastinum, projected near the helium of the right lung. Computed tomography of the thorax showed a cystic expansible formation, without impregnation by the contrast agent, located in the posterior mediastinum. The patient was submitted to bronchoscopy, videothorascopy and, finally, to thoracotomy, in which the cystic lesion was resected, whose definitive diagnosis, after histopathological examination, was bronchogenic cyst.

    Oral myofibroma is a rare tumour which usually occurs in children and has been reported in the mandible, tongue, buccal mucosa with only a few cases reported from the gingiva. It appears alarming clinically due to its fast growth which may mimic a malignancy. However, it is completely benign and is usually treated by complete surgical excision with excellent prognosis. Clinically, myofibroma presents as a single swelling when it occurs on the gingiva, and more common lesions such as fibrous epulis, pyogenic granuloma and peripheral odontogenic fibroma, myofibroma are usually considered in the differential diagnosis. We present 4 additional cases of gingival myofibroma in children. Their ages ranged from 7 to 14 years. Three were girls and 1 patient was a boy. All presented with solitary gingival growths, ranging from 3 weeks to 2 months in duration, and raised the clinical diagnoses of peripheral giant cell granuloma, pyogenic granuloma and fibrous epulis. Histopathology of incisional biopsies revealed proliferation of streaming and whorled fascicles of spindle cells around slit-like vascular spaces. The spindle cells were cytologically bland and were immunopositive for vimentin and smooth muscle actin, but were negative for desmin and S-100 protein. All were treated by surgical excision.

  13. Worth it? Findings from a study of how academics assess students’ Web 2.0 activities

    Full Text Available Educational commentators have offered many pedagogical rationales for using Web 2.0 to support learning in higher education, and academics are being encouraged to find ways for their students to use social web technologies. Questions arise as to the value of these activities compared to more conventional assignments, and whether implementing such changes to student assessment is worth the effort. We conducted a survey of academics’ assessment of students’ Web 2.0 activities in Australian universities and found that this form of assessment is being conducted by a small number of academics, in a range of fields of study, but mainly in Humanities and Social Sciences, with varying kinds of intended and actual learning outcomes. Blogging and wiki-writing predominate, low and medium-stakes assessment are most common, and different methods of marking and feedback are in use. Qualitative feedback from the survey and follow-up interviews gave further insights into benefits and challenges of Web 2.0 assessment in relation to pedagogy, policy and practice. It appears that academics’ conservative approaches to conducting assessment and their novice approaches to utilising social web technologies are factors which seriously limit realising the potential of Web 2.0 for medium or high-stakes assessment.

    Fibrolipomatous hamartoma (FLH) of the nerve is a rare, benign tumor that most commonly originates from the median nerve of the hand. Fibrofatty tissue proliferates around the nerve and infiltrates the epineurium and perineurium. We present two cases of pathologically proven FLH of a digital branch of the median nerve, without macrodystrophy with magnetic resonance imaging, surgical and pathologic findings. Magnetic resonance images of both cases show well-circumscribed mass with fat signal intensity around an enlarged digital branch of the median nerve and characteristic coaxial-cable-like appearance on axial images and spaghetti-like appearance on coronal images.

    Problems in communication among the government, enterprise, experts and so on and the society and people, now confront us in several areas of science and technology. In order to be accepted by the society, each area of science and technology has experienced common processes such as beginnings, business, society introduction, problem renovation and maturity. Each area can be positioned based on the degree of maturity, which helps to find solutions of the problems. Arrangement and analysis of academic findings and practical cases on risk communications in nuclear energy are described. (T. Tanaka)

    MRI of ten atypical MCT were reviewed correlating with pathology and to clarify why they did not include any hyperintense area on T1-weighted images (T1WI). Nine of the ten cases had a few sebaceous glands. Intra-tumoral chemical shift artifact was noted in four and the presence of the finding was diagnostic of the disease. Two with abundant thyroid tissue showed multilocular cyst whose fluid in some loculi indicated hyperintense on T1WI and hypointense on T2WI, which was similar to MR findings of struma ovarii. Four with complication such as hemorrhagic necrosis demonstrated inhomogeneous signals and they were hardly diagnosed correctly. (author)

    A pulmonary mucinous cystadenocarcinoma is an extremely rare tumor that is considered to be a cystic variant of mucin-producing lung adenocarcinoma. We present a case of pulmonary mucinous cystadenocarcinoma in a 54-year-old woman. Chest CT scans showed a 4.3-cm-sized, lobulated, well-defined, and homogeneous mass in the right middle lobe with peripheral stippled calcifications that demonstrated low-attenuation with no enhancement after contrast administration; 18F-fluorodeoxyglucose (FDG) PET/CT demonstrated mild heterogeneous FDG uptake. The mass was diagnosed as adenocarcinoma with mucin production by transbronchial lung biopsy. Right middle lobectomy was performed, and the pathologic examination disclosed a pulmonary mucinous cystadenocarcinoma.

    Infantile Refsum disease (IRD) is a peroxisome biogenesis disorder (PBD), and is part of a larger group of diseases called leukodystrophies, which are inherited conditions that damage the white matter of the brain and affect motor movements. Multiple signs and symptoms of IRD begin in infancy and progress through early childhood, including hearing and visual impairment, intellectual and growth impairment, seizures, liver involvement, and orofacial and dental abnormalities. This paper presents a case history of a 12-year-old female patient with IRD who underwent dental rehabilitation in the operating room under general anesthesia and includes a 2-year follow-up. Medical, dental, and management considerations in the care of this child's condition are presented. This paper also discusses the importance of a multidisciplinary approach in the management of children with special needs.

  19. FDG-PET findings in fronto-temporal dementia: A case report and review of literature

    International Nuclear Information System (INIS)

    Fronto-temporal lobar degeneration (FTLD) is a clinically and pathologically heterogeneous syndrome, characterized by progressive decline in behavior or language associated with degeneration of the frontal and anterior temporal lobes. Three distinct clinical variants of FTLD have been described. Despite the difficulties, accurate diagnosis is critical because the clinical management differs for Alzheimer's disease (AD) and FTLD. Positron emission tomography with fluro-deoxy-glucose (FDG-PET) typically shows sufficient abnormalities that can be used to improve the accuracy of distinguishing AD from FTLD in individual cases. Though temporo-parietal hypometabolism is sensitive in diagnosis of AD, it is less specific. The importance of evaluating the cingulate and anterior temporal cortices for arriving at a diagnosis of FTLD is stressed

    A 38-year-old woman was referred to our institution due to epigastralgia. She presented with obstructive jaundice and eosinophilia. Endoscopic retrograde cholangiopancreatography showed diffuse narrowing from the distal common bile duct to the bifurcation of the hepatic ducts. An endoscopic plastic biliary stent was inserted; the specimen obtained from the common bile duct wall revealed dense infiltration by eosinophils.Treatment was started with prednisolone 60 mg daily.The patient's biliary stenosis and eosinophilia gradually improved. Eosinophilic infiltration in the lungs or stomach is relatively common, but it is rare in the common bile dud. Most of the reported cases of eosinophilic cholangitis presented with eosinophilia; our patient's eosinophil count was over 1000/mm3. Since our patient had allergies to pollen and house dust, a relationship between the allergies and the eosinophilic cholangitis was suspected, but no cause was identified.

    Peliosis hepatis is a rare condition characterized by dilatation of hepatic sinusoids and blood-filled spaces in the liver mainly observed in subjects exposed to toxic substances or estrogens, which is frequently asymptomatic. Non-cirrhotic idiopathic portal hypertension (NCIPH) is also a vascular disease of the liver rarely observed in European countries, which is usually diagnosed only when the hemorrhagic complications of portal hypertension occur. We report a case of NCIPH in a young Caucasian male who was diagnosed with liver peliosis, showing ultrasonographic and endoscopic signs of portal hypertension four years after. A second biopsy was diagnostic for NCIPH. Even if the pathogenesis remains obscure, peliosis hepatis can be considered as an early sign of vascular disease of the liver, which may progress to more definite conditions.

    We describe a case of aneurysm of the vein of Galen (AVG), which was diagnosed by intrauterine US, MRI and MRA. The baby girl was born at 35 weeks' gestation. She had severe clinical symptoms at birth and died at 29 h of age from intractable congestive heart failure. Intrauterine US detected an intracranial aneurysm and cardiomegaly due to excessive arteriovenous shunting. Intrauterine MRI (SSFSE) confirmed the diagnosis of AVG, and intrauterine MRA (2D-TOF) successfully demonstrated the anatomical structure of the AVG. MRA may be a useful additional sequence to evaluate AVG, and 2D-TOF is thought to be an appropriate technique for scanning fetal AVG. (orig.)

    Alveolar adenoma is a rare pulmonary neoplasm with a female predominance, and it was considered to be a histologic variant of sclerosing hemangioma in the past. A chest X-ray usually shows a well-defined, peripheral, solitary nodule similar to that of sclerosing hemangioma. Chest CT shows a solitary, well-defined, peripheral nodule with homogeneous density and no contrast enhancement, which is contrary to marked contrast enhancement of sclerosing hemangioma. We report the first case of alveolar adenoma with spotty enhancement of the nodule similar to that of sclerosing hemangioma on contrast enhanced CT, based on the presence of stromal vessels in the interstitium of the compact alveolar area on histopathologic comparison.

    Angioleiomyomas are a rare benign smooth muscle tumor arising from vessel walls. Although angioleiomyomas are most frequently reported in the lower extremities and in middle-aged female patients, they can be found throughout the body in male and female adults of all ages. We report a rare case of an angioleiomyoma of the left 3rd digit in a 31-year-old man, which appeared as a small, well defined mass with multiple vascular structures on Doppler sonogram and MRI. The tumor was diagnosed by pathology as an angioleiomyoma. Although angioleiomyomas are relatively infrequent, they should be considered in the differential diagnosis when multiple tortuous vascular structures are seen within a well demarcated mass in extremities on Doppler sonogram and MRI.

    Brain injury from carbon monoxide (CO) poisoning occurs due to tissue hypoxia and direct CO-mediated histotoxicity. Recently developed susceptibility-weighted imaging (SWI) is sensitive for the detection of accumulated hemosiderin and iron secondary to cerebral hemorrhage. Therefore, we hypothesized that SWI may be helpful for identifying petechial hemorrhagic transformation secondary to acute hypoxic damage during subacute CO intoxication. Our case series with subacute CO intoxication revealed that the SWIs of all patients showed low signal intensities in the globus pallidus, representing the accumulation of iron or calcium secondary to hypoxic damage from acute CO intoxication. These results suggest that SWI may be a useful MR technique for illustrating brain damage in subacute delayed CO intoxication. PMID:21914555

    Xanthogranulomatous pyelonephritis is an uncommon chronic renal infection, which is usually found on middle-aged women and is rare in infant. Sometimes it forms focal mass like lesion of kidney with pathologically characteristic lipid-laden macrophage. A 1-month female infant was admitted for fever and moaning sound. On work-up of urinary tract infection, abdomen ultrasonography and computed tomography revealed a large mass on the upper portion of right kidney and PET/CT showed homogeneously increased {sup 18}F-FDG uptake. The radical nephrectomy of right kidney was performed and histology revealed a focal xanthogranulomatous pyelonephritis. To our knowledge, this is the first report presenting the finding of {sup 18}F-FDG PET/CT in the childhood xanthogranulomatous pyelonephritis.

    A previously healthy 39-year-old woman suddenly became stuporous following a slight upper respiratory infection. She went into a coma within a few hours. On admission to our hospital, adenine arabinoside was administered upon the diagnosis of herpes simplex encephalitis, but it had no apparent effect. The patient showed moderate leukocytosis, but no other abnormal laboratory data. Serological examinations for virus titer were all negative. A CT scan on the 9th day showed a diffuse low-density area extending into the cerebral and cerebellar white matter, but no contrast-enhancement effect or midline shift was observed. She has since remained in a coma, and repeated CT scans have revealed marked ventricular dilatation. The clinical course, laboratory data, and CT findings suggest acute disseminated encephalomyelitis, but acute hemorrhagic leukoencephalitis cannot exactly be ruled out. Magnetic resonance imaging demonstrated a widespread white-matter lesion, while positron-emission CT demonstrated a dysfunction in both the white and gray matter.

The chief complaint of these patients was either chorea (n=3D1) or mental change (n=3D2). They showed hyperglycemia, but physical examination and laboratory data revealed no other abnormalities. In all patients, non-enhanced CT scanning revealed high-attenuated lesions in the unilateral putamen. In two of the three patients, brain MRI performed two days after the onset of symptoms showed an abnormally high signal on T1-weighted images and a low signal on T2-weighted images. One patient had a history of diabetes mellitus, and another had acute myocardiac infarction. The third had no specific history. After the correction of hyperglycemia, the patient's symptoms subsided and diabetes mellitus was diagnosed. (author)

    Juvenile xanthogranuloma (JXG) is a proliferative histiocytic disorder experienced during childhood and adolescents. JXG commonly presents as a solitary cutaneous lesion. Despite the term 'juvenile', development of the disease during adulthood is possible, although spinal JXG is extremely rare in adults. We describe a 67-year-old female patient who presented with an intradural-extramedullary (IDEM) tumor of the spinal cord. Magnetic resonance imaging (MRI) findings indicative of JXG of the spinal cord were seen, which was then confirmed pathologically. A lumbar spinal MRI with contrast enhancement showed an oval-shaped, well-defined IDEM tumor at the L1 level. This tumor had mixed signal intensity on the T1-weighted image and high signal intensity on the T2-weighted image. Central homogenous enhancement was observed after contrast administration.

    Full Text Available BACKGROUND: Prisons offer a fertile setting for the transmission of tuberculosis due to the presence of many classic risk factors for both infection and disease: overcrowding, poor ventilation, and little sunlight. Prisoners are often malnourished and have poor hygiene and are more likely to have a background of alcohol and drug abuse. OBJECTIVES: To determine the prevalence of prisoners with respiratory symptoms and pulmonary tuberculosis (PTB through active case finding in a prisoner population of the county jail of Carapicuíba, and to study possible related variables. METHODS: This was a cross-sectional study, and respiratory symptomatic individuals (RSI were detected through active case finding. Socio-demographic data were collected from inmates' judicial history using a specific questionnaire. The RSI provided sputum specimens for detection of acid fast bacilli and culture for mycobacterium identification. RESULTS: Among the 397 prisoners studied, 154 reported respiratory symptoms for more than three weeks, and were considered RSI; the variables associated with RSI were: having already been tried and incarcerated for more than six months and seven were diagnosed as PTB (1,763 cases/ 100,000 inhabitants. CONCLUSIONS: The prevalence of RSI and PTB cases were respectively 39 and 35 times greater than the general population.INTRODUÇÃO: Estabelecimentos prisionais são um campo favorável para a transmissão de tuberculose (TB, devido a presença de vários fatores de risco clássicos, tanto para a infecção como para a doença: aglomeração, falta de ventilação e de iluminação, como também o fato de os detentos receberem uma nutrição deficitária e os locais possuí-rem condições de higiene precárias; uma grande proporção dos detentos apresentam história pregressa de alcoolismo e uso de drogas ilícitas nas dependências desses estabelecimentos.

  12. Finding the needle in a haystack: identification of cases of Lynch syndrome with MLH1 epimutation.

    Science.gov (United States)

    Hitchins, Megan P

    2016-07-01

    Constitutional epimutation of the DNA mismatch repair gene, MLH1, represents a minor cause of Lynch syndrome. MLH1 epimutations are characterized by the soma-wide distribution of methylation of a single allele of the MLH1 promoter accompanied by constitutive allelic loss of transcription. 'Primary' MLH1 epimutations, considered pure epigenetic defects, tend to arise de novo in patients without a family history or any apparent genetic mutation. These demonstrate non-Mendelian inheritance. 'Secondary' MLH1 epimutations have a genetic basis and have been linked to non-coding genetic alterations in the vicinity of MLH1. These demonstrate autosomal dominant inheritance. Despite convincing evidence of their role in causing Lynch-type cancers, routine screening for MLH1 epimutations has not been widely adopted. Complicating factors may include: the need to perform additional methylation-based testing beyond the standard genetic screening for a germline mutation; the lack of a consensus algorithm for the selection of patients warranting MLH1 epimutation testing; overlapping molecular pathology features of MLH1 methylation and loss of MLH1 expression with more prevalent sporadic MSI cancers; the rarity of MLH1 epimutation; the variable inter-generational inheritance patterns; and the cost-effectiveness of screening. Nevertheless, a positive molecular diagnosis of MLH1 epimutation is clinically important because carriers have a high personal risk of developing metachronous Lynch-type cancers, and their relatives may also be at risk of carriage. Extending existing universal and clinic-based screening algorithms for Lynch syndrome to include an additional arm of selection criteria for cases warranting MLH1 epimutation testing could provide a cost-effective means of diagnosing these cases.

  13. Case study: Findings and lessons learned from investigating a uranium intake and the corresponding dose calculations

    International Nuclear Information System (INIS)

    Full text: Purpose: To discuss the findings of an investigation into uranium intake and to discuss the lessons learned from the subsequent bioassay monitoring and dose calculations. Method: An investigation was held to determine direct and root causes after elevated air concentration levels were reported during the execution of an ad-hoc task. A programme of bioassay monitoring (urine sampling and lung counts) was implemented for the involved staff and committed effective doses were calculated. Major findings of the investigation: a) Inadequate pre-task assessment led to hazards not being identified and subsequently proper control measures were not implemented; b) Inadequate localised control of contamination led to contamination of worker's clothes and faces and contamination of rest of area; c) Workers were complacent which led to a lapse in safety awareness and subsequently they removed their face masks during the task. Problems experienced with bioassay monitoring and dose calculations: a) Some bioassay samples were not taken or were given incorrectly; b) Calculating doses were difficult due to lack of information regarding date of intake; whether there were other possible intakes; and the physiochemical nature of the uranium; c) Weak correlation between predicted and actual bioassay data; d) Period between starting bioassay monitoring and the actual event was too long. Conclusions: a) Shortcomings in the control of contamination with protective clothing and during the execution of ad-hoc tasks; b) Identifying hazards and assessing it is extremely dependant on the skill and capabilities if the Radiation Protection Officers; c) Instructions to workers regarding sampling of urine and arrangements around the sampling should be very specific with only one person responsible for managing the process; d) Be aware of the psychological impact on the affected workers; e) 2 nd Independent dose calculation important for verifying doses; f) Detection capabilities and

    Full Text Available Adrenal gland tumors are common in humans and in several animal species. Studies concerning this neoplasia in human medicine indicate that clinical signs have a high variability. Adrenal adenomas can be occasionally observed in asymptomatic patients during tomographic studies while estrogen-secreting tumors, known as "feminizing adrenal tumors" (FATs, have been rarely reported. The aim of this study is to describe for the first time the Imaging findings of a captivity lion affected by a neoplastic secreting adrenal tumour. An 8 year-old male lion with progressive lack of secondary sex characteristics, disorexia and weight loss was referred to our Institution. The patient was chemically immobilized to undergo general clinical evaluation, hematologic, serum biochemical and hormonal profile, FIV and FeLV tests. Three months later a total body computed tomography and abdominal ultrasonography were performed. Liver and left adrenal lesions FNABs were performed. Imaging findings showed the presence of an extended expansive neoplastic lesion on the left adrenal gland (40x39x37 mm with right adrenal gland atrophy. Generalized hepatopathy associated with a suspected intrahepatic cholestasis was confirmed by ultrasonography. Cytological evaluation ruled out the presence of neuroendocrine cells without malignancy evidences compatible with the adenomatous nature of the lesion, associated with moderate degenerative hepatopathy. Blood tests reported an estradiol concentration of 462 ng/dl. To our knowledge, this is the first description of adrenal mass in a lion associated with secondary feminization, inappetence and high values of hematic estradiol, referable to a feminizing adrenal tumor (FAT.

    Atypical teratoid/rhabdoid tumor rarely occurs in the CNS, though is most common in infants under two years of age. It is characterized by unique histologic features, has an extremely aggressive natural course, and is located mainly in the infratentorial region. Radiologically, it is difficult to distinguish from primitive neuroectodermal tumor or medulloblastoma. We report the radiologic findings of two cases of atypical teratoid/rhabdoid tumor.

There are arcs of three types: ordinary arcs, multiple arcs and multi-arcs. Each multiple and multi-arc is a union of k linked arcs, which are adjusted with each other. The network constructing rules are described. The definitions of a divisible network and some associated subjects are stated. The important property of the divisible network is that every divisible network can be partitioned into k parts, which are adjusted on the linked arcs of each multiple and multi-arc. Each part is the ordinary transportation network. The main results of the article are the following subclasses of the problem of finding the maximal multiple flow in the divisible network. 1. The divisible networks with the multi-arc constraints. Assume that only one vertex is the ending vertex for a multi-arc in k −1 network parts. In this case the problem can be solved in a polynomial time. 2. The divisible networks with the weak multi-arc constraints. Assume that only one vertex is the ending vertex for a multi-arc in s network parts (1 ≤ s < k − 1 and other parts have at least two such vertices. In that case the multiplicity of the multiple flow problem can be decreased to k − s. 3. The divisible network of the parallel structure. Assume that the divisible network component, which consists of all multiple arcs, can be partitioned into subcomponents, each of them containing exactly one vertex-beginning of a multi-arc. Suppose that intersection of each pair of subcomponents is the only vertex-network source x0. If k = 2, the maximal flow problem can be solved in a polynomial time. If k ≥ 3, the problem is NP-complete. The algorithms for each polynomial subclass are suggested. Also, the multiplicity decreasing algorithm for the divisible network with weak multi-arc constraints is formulated.

    Full Text Available OBJECTIVE: We sought to validate a case-finding algorithm for human immunodeficiency virus (HIV infection using administrative health databases in Ontario, Canada. METHODS: We constructed 48 case-finding algorithms using combinations of physician billing claims, hospital and emergency room separations and prescription drug claims. We determined the test characteristics of each algorithm over various time frames for identifying HIV infection, using data abstracted from the charts of 2,040 randomly selected patients receiving care at two medical practices in Toronto, Ontario as the reference standard. RESULTS: With the exception of algorithms using only a single physician claim, the specificity of all algorithms exceeded 99%. An algorithm consisting of three physician claims over a three year period had a sensitivity and specificity of 96.2% (95% CI 95.2%-97.9% and 99.6% (95% CI 99.1%-99.8%, respectively. Application of the algorithm to the province of Ontario identified 12,179 HIV-infected patients in care for the period spanning April 1, 2007 to March 31, 2009. CONCLUSIONS: Case-finding algorithms generated from administrative data can accurately identify adults living with HIV. A relatively simple "3 claims in 3 years" definition can be used for assembling a population-based cohort and facilitating future research examining trends in health service use and outcomes among HIV-infected adults in Ontario.

    Objective: To present the magnetic resonance (MR) imaging findings of 78 patients with meningiomas diagnosed in a single institution. Method: 78 patients with histological proven intracranial meningioma were studied. There were 52 female and 26 male patients (median=56 years). All MR imaging examinations were performed with 1.5-T MR imaging unit with standard protocol. The images were studied by two neuroradiologists, who reached the decisions regarding the findings by consensus. Results: Most of the tumors showed low signal on T1- (60%) and high signal on T2- (68%) and FLAIR (69%) weighted images. Also, the lesions showed heterogeneous signal on T1 (60%), T2 (68%) and FLAIR (64%) sequences. After contrast administration, 83% (n=65) of the tumors presented accentuated and 17% (n=13) showed moderate enhancement. The tumors were located in the frontal lobe in 44% of the cases, in the parietal lobe in 35%, the occipital lobe in 19% and the temporal lobe in 12% of the patients. Areas of vasogenic edema around the tumors were seen in 90% of the cases. Twenty six per cent of the cases showed bone infiltration, and the dural tail sign was seen in 59% of the tumors. Conclusion: Intracranial meningiomas usually show heterogeneous low signal on T1- and high signal on T2-weighted and FLAIR images, with intense enhancement after contrast administration. The frontal and parietal lobes are commonly affected. In addition, brain edema, dural tail sign and bone infiltration are the most frequent associated findings. (author)

    The aim of the study was to explore the experiences of night nurses. An interpretative phenomenological study was undertaken, and 35 nurses working in Italian medical, surgical and intensive care units were purposely recruited. Data were gathered in 2010 by semi-structured interviews, collecting nurses' narratives, memorable cases and metaphors, aimed at summarising the essence of work as a nurse during the night. The experience of night nursing is based on four interconnected themes: (i) working in a state of alert, (ii) growing by expanding autonomy and responsibility, (iii) assuring sensitive surveillance and (iv) experiencing deep intimacy. Memorable episodes were polarised along (i) expected/unexpected events; (ii) positive/negative epilogues; and (iii) life/death issues. Many of the emergent metaphors described working during the night as being in the middle of a space where an apparent calm scene takes place, but unpredictable factors may suddenly change the order of events and the outcomes, creating chaos. Working during the night alerts nurses, who increase autonomy, expanding their role and assuming more responsibility with respect to that assumed during daily shifts. The nurses' clinical reasoning is based on data they carefully listen to, and on the meaning that nurses give time by time to different noises and silence. While in the past a sense of companionships was reported, a loneliness or a 'neutral' experience concerning the relationships with colleagues seems to prevail during night nursing. Working night shifts is a complex task, and specific training must be assured to students/novices.

    Full Text Available A pregnant Saanen doe aging 1.5-year and weighing 40 kg was presented to the Large Animal Unit of Universiti Putra Malaysia Veterinary Hospital with history of inability to stand up. Transabdominal ultrasonography of the animal revealed two live fetuses at late pregnancy. Blood examination revealed decreased lymphocyte numbers, and increased monocytes count. Biochemical analyses showed marked decrease in glucose level and elevated level of aspartate aminotransferase (AST and creatine kinase (CK. The goat was administered with 200 mL 20% Dextrose (G-20, NaCl solution (at 1.3 mL/animal, Flunixine meglumine (at 2.2 mg/kg bwt, and Vitavet multivitamin (at 1 mL/10 kg bwt. The prognosis of the case was grave, and the goat was sacrificed in order to save the fetuses. However, the fetuses were died within 10 min. Necropsy of the doe showed pale, yellow and friable liver and congested lungs, while histopathological evaluation of the liver showed diffuse hepatic lipidosis. Pregnancy toxemia in doe can be prevented by providing proper nutrition.

    Full Text Available Odontomas are the most common benign tumors of odontogenic origin. They are normally diagnosed on routine radiographs, due to the absence of symptoms. Histopathologic evaluation confirms the diagnosis especially in cases of complex odontoma, which may be confused during radiographic examination with an osteoma or other highly calcified bone lesions. The micro-CT is a new technology that enables three-dimensional analysis with better spatial resolution compared with cone beam computed tomography. Another great advantage of this technology is that the sample does not need special preparation or destruction in the sectioned area as in histopathologic evaluation. An odontoma with CBCT and microtomography images is presented in a 26-year-old man. It was first observed on panoramic radiographs and then by CBCT. The lesion and the impacted third molar were surgically excised using a modified Neumann approach. After removal, it was evaluated by histopathology and microtomography to confirm the diagnostic hypothesis. According to the results, micro-CT enabled the assessment of the sample similar to histopathology, without destruction of the sample. With further development, micro-CT could be a powerful diagnostic tool in future research.

    2012-05-01

    Full Text Available A 43-year-old man with a long history of dyspnea which had progressively worsened over the preceding month is presented.He had worked in an antimony mine for 3 years. Radiologically, there were diffuse reticulonodular shadowing opacities in both lung parenchymas. Histopathologic examination of the open-lung biopsy specimen revealed alveolar spaces filled with dust-laden macrophages and amorphous proteinaceous semifluid, the latter being immunoreactive for Human Surfactant Apoprotein A, associated with marked interstitial accumulation of the similar-looking macrophages along the bronchovascular bundles and mild interstitial fibrosis. Silicotic nodules or mixed dust fibrosis were not seen. The patient was diagnosed as silicoproteinosis with unusual histopathological features because he had worked in an antimony mine for only 3 years and had 86% silica in a mineralogical analysis.Pneumoconiosis is a rare lung disease which may be confused with other interstitial lung diseases. Clinical, radiological and unusual histopathologic features of this rare case are presented and discussed with the differential diagnosis, especially of mixed dust pneumoconiosis.

    This retrospective study is about 49 cases of tumors of the vaterian region collected between 1976 and 2001. Tumors of the vaterian region represented 7% of the bilio-pancreatic tumors. The study was about 18 women and 31 men, with sex-ratio of 1.7. The mean age was 61 years. Treatment was surgical : cephalic duodeno-pancreatectomy (28 patients) or ampullectomy (5 patients). Rate of tumor resectability was 69.4%. Bilio-digestive derivation was practiced on 13 patients and therapeutic abstention was decided for 3 patients. Age over 65 years, rate of bilirubine superior to 120 mmol/l and surgery done in emergency were elements of bad prognosis that increased post-operative mortality of following cephalic duodeno-pancreatectomy. Global mortality and morbidity were respectively 16% and 24%. Factors of poor prognosis were essentially: Tumor of large size, infiltration of the surrounding structures and tumor with metastases. The survival after bilio-digestive derivation didn't pass the 8 months. Five year survivals cephalic duodeno-pancréatectomy represented 20%. It depended on the degree of the local invasion. This 5 years survival rate to was 85% for stage I (classification of Martin) and 10% for stage IV.

    Background Aquired immune deficiency syndrome (AIDS) presents a challenge to medical researchers because of its unique pathological and clinical picture. The clinical data, particularly autopsy evidence, from China have failed to provide enough pathological and etiological evidence for AIDS diagnosis, which impairs the reliability of the diagnosis and our full understanding of the occurrence and development of AIDS complications. The purpose of this study was to investigate the imaging and pathologic characteristics of AIDS.Methods Autopsy, imaging and pathological data from 8 cases of AIDS were retrospectively analyzed. Routine CT scanning of different body parts was performed during their periods of hospitalization. Transverse CT scanning was conducted from the skull to the pelvis immediately after the occurrence of death. After routine formalin fixing, 7 cardevers were cross sectioned for autopsy in freezing state and 1 for gross autopsy. Tissues were obtained from each section and organs for pathological examinations.Results The autopsy data indicated the presence of parasitic infections, bacterial infections, fungal infections, and virus infections in AIDS patients. Pneumocystis pneumonia, pulmonary tuberculosis, coccobacteria pneumonia, Aspergillus pneumonia, cytomegalovirus pneumonia, toxoplasma encephalitis, lymphoma and cerebrovascular diseases were found in these patients.Conclusions During the course of AIDS progression, the concurrent multiple infections as well as tumor development may result in multiple organ pathological changes and clinically complex symptoms that further complicate the imaging and pathological manifestations, thus resulting in difficult differential diagnosis. A combination of imaging data and autopsy data can help to clarify the diagnosis.

    Full Text Available Cloacal malformation is an extremely rare fetal pathological condition that presents as a variety of defects. It predominantly affects females, with prevalence of 1 in 50,000 births. Prenatal ultrasonography on a 20-year-old caucasian woman (G4P1A2 at 33 weeks of pregnancy showed the fetus having a large cystic mass in the lower abdomen with a single septum, bilateral hydronephrosis, ambiguous genitalia, and a single umbilical artery. The pregnancy developed accentuated oligohydramnios, and presence of a fetal brain-sparing effect was diagnosed using arterial Doppler velocimetry. The newborn showed abdominal distension, ambiguous genitalia, and rectal atresia, with a single perineal opening. Pelvic ultrasound done on the first day after delivery revealed the presence of a large retrovesical septated cystic mass of dense content in the fetal abdomen, and bilateral hydronephrosis. Hysterotomy was performed, and 70 mL of dense liquid was drained through an abdominal colostomy. The infant died on the 27th day of life as a result of infectious complications. Prenatal diagnosing of female urogenital anomalies is usually difficult because of their rarity, different types of manifestation, and lack of characteristic ultrasound signs. Presence of a septated cyst with dense content in the fetal abdomen confirms the finding of hydrometrocolpos, thus raising clinical suspicion of a cloacal anomaly.

    Full Text Available Building national brand plays an important role on today's economy to attract interested tourists in visiting various countries. There are different factors impacting national brand such as advertisement, natural attraction, etc. In this paper, we perform an empirical investigation to find the impact of ten most important factors on building brand. The study designs and distributes a questionnaire among 384 international tourists who visited Iran during the year of 2010 and it uses factor analysis to group important factors. The results extract four groups; the first factor includes three most important components including satellite advertisement programs, public awareness on economical power and public awareness on specialized symposium and conferences. The second factor includes three other important factors, which are public awareness on human right, advertisement programs through distribution brushers and internet advertisement. The third factor includes two variables, which are public awareness on education and access to educational services and introducing cultural heritage. Finally, the last factor includes introducing natural attraction and advertisement programs through distribution brushers.

  12. Laparoscopic finding of female infertility-a study of 186 cases at a tertiary care hospital

    International Nuclear Information System (INIS)

    Objective: To study the various causes of female infertility, diagnosed at laparoscopy. Study Design: Descriptive study. Place and Duration of Study: The study was conducted at Military Hospital Rawalpindi, Pakistan from April 2008 to December 2010. Patients and Methods: A series of 186 patients, having either primary or secondary infertility admitted through gynae outpatient department undergoing diagnostic laparoscopy and meeting inclusion criteria were studied. The data was collected prospectively and analysed in the form of frequency and percentages by using SPSS version 10. Results: Amongst the cohort of 186 patients, 148 (79.6%) had primary and 38 (20.4%) had secondary infertility. Their ages ranged from 20 to 43 years. Mean age of study participants was 30.14 +- 4.04 years. Mean duration of infertility was 9.5 years. No laparoscopic abnormality was found in 51 (27.9%), while there were abnormal findings in 135 (72.6%) patients. Conclusion: Commonest etiological factor was tubal blockade in both types of infertility. Other factors were endometriosis, pelvic adhesions and fibroids. Laparoscopy is minimally invasive yet a reliable procedure for visualization of internal architecture of the female pelvis. (author)

  14. Incidental finding of unilateral isolated aplasia of serratus anterior muscle and winged scapula on chest radiograph: A case report

    International Nuclear Information System (INIS)

    The isolated aplasia of the serratus anterior muscle with winging of scapula is very rare, and only a few cases are reported. Here, we present a case of a 30-year-old Korean male who initially presented with a left flank pain. His physical exam did not show any significant finding in his right shoulder. However, his chest radiograph showed absence of right serratus anterior muscle and slightly elevated and medially rotated right scapula. Subsequent CT scan showed the right serratus anterior muscle aplasia and medial winging of the right scapula. This case is unique in two aspects. First, the combination of abnormalities is different from the typical congenital abnormalities involving shoulder girdle, such as Sprengel deformity or Poland syndrome. Secondly, this was incidentally diagnosed with chest radiograph, without clinical impression. Careful reading of chest radiograph can help the radiologists to detect such clinically silent abnormalities.

    Objective. To compare information gained by ultrasonography and magnetic resonance imaging (MRI) in chronic achilles tendinopathy with regard to the nature and severity of the lesion. Design. Imaging of both achilles tendons with ultrasonography and MRI was performed prior to unilateral surgery. Operative findings and histological biopsies together served as a reference. Patients. Twenty-seven patients (22 men, 5 women; mean age 44 years; 21 athletes) suffering from chronic achilles tendinopathy participated in the study. Eighteen patients had unilateral and 9 had bilateral symptoms. Results and conclusions. Surgical findings included 4 partial ruptures, 21 degenerative lesions and 2 macroscopically normal cases. Microscopy revealed tendinosis (degeneration) in all tendon biopsies, including cases with a partial rupture, but only slight changes in the paratendinous tissues (paratenon). Ultrasonography was positive in 21 of 26 and MRI in 26 of 27 cases. Severe intratendinous abnormalities and a sagittal tendon diameter >10 mm suggested a partial rupture. In tendons with a false negative result histopathological changes were mild and a tendency towards a better clinical outcome was noted in the sonographic cases. Assessment of the paratenon was unreliable with both methods. Ultrasonography and MRI give similar information and may have their greatest potential as prognostic instruments. (orig.).

  16. Intensified tuberculosis case finding among malnourished children in nutritional rehabilitation centres of Karnataka, India: missed opportunities.

    Directory of Open Access Journals (Sweden)

    Prashant G Bhat

    Full Text Available BACKGROUND: Severe acute malnutrition (SAM is the most serious form of malnutrition affecting children under-five and is associated with many infectious diseases including Tuberculosis (TB. In India, nutritional rehabilitation centres (NRCs have been recently established for the management of SAM including TB. The National TB Programme (NTP in India has introduced a revised algorithm for diagnosing paediatric TB. We aimed to examine whether NRCs adhered to these guidelines in diagnosing TB among SAM children. METHODS: A cross-sectional study involving review of records of all SAM children identified by health workers during 2012 in six tehsils (sub-districts with NRCs (population: 1.8 million of Karnataka, India. RESULTS: Of 1927 identified SAM children, 1632 (85% reached NRCs. Of them, 1173 (72% were evaluated for TB and 19(2% were diagnosed as TB. Of 1173, diagnostic algorithm was followed in 460 (37%. Among remaining 763 not evaluated as per algorithm, tuberculin skin test alone was conducted in 307 (41%, chest radiography alone in 99 (13% and no investigations in 337 (45%. The yield of TB was higher among children evaluated as per algorithm (4% as compared to those who were not (0.3% (OR: 15.3 [95%CI: 3.5-66.3]. Several operational challenges including non-availability of a full-time paediatrician, non-functioning X-ray machine due to frequent power cuts, use of tuberculin with suboptimal strength and difficulties in adhering to a complex diagnostic algorithm were observed. CONCLUSION: This study showed that TB screening in NRCs was sub-optimal in Karnataka. Some children did not reach the NRC, while many of those who did were either not or sub-optimally evaluated for TB. This study pointed to a number of operational issues that need to be addressed if this collaborative strategy is to identify more TB cases amongst malnourished children in India.

  17. Radiographic findings in cats with intranasal neoplasia or chronic rhinitis: 29 cases (1982-1988)

    International Nuclear Information System (INIS)

    Objective: To compare radiographic findings and determine useful criteria to differentiate between intranasal neoplasia and chronic rhinitis in cats. Design: Retrospective study. Animals: Cats with chronic nasal disease caused by neoplasia (n = 18) or by chronic rhinitis (n = 11). Procedure: Radiographs were reviewed by 3 radiologists, followed by group review. Diagnosis was determined by intranasal biopsy or necropsy, and specimens were reviewed by a pathologist to confirm cause and histologic diagnosis. Results: Lymphosarcoma was the most common (n = 5) of the 6 histopathologic types in the neoplasia group. Cats in the neoplasia and chronic rhinitis groups had a high prevalence of aggressive radiographic lesions. Prevalence of a facial mass in cats with neoplasia (8/18) versus in those with chronic rhinitis (4/11) and of deviation (9/18 vs 6/11, respectively) or lysis (12/18 vs 7/11) of the nasal septum was similar. However, significantly (P = 0.02) more cats with neoplasia than with chronic rhinitis (13/16 vs 3/7, respectively) had unilateral turbinate destruction/lysis. Additionally, unilateral lateral bone erosion and loss of teeth associated with adjacent intranasal disease were more prevalent in cats with neoplasia (7/8 and 5/18, respectively) than in cats with chronic rhinitis (1/3 and 0/11, respectively). Clinical Implications: Features that may assist in radiographic diagnosis of neoplasia include the appearance of unilateral aggressive lesions, such as lysis of lateral bones, nasal turbinate destruction, and loss of teeth. Bilaterally symmetric lesions are more suggestive of chronic rhinitis than of neoplasia

    The abdominal tumors in children are different from those of adults in respect to age brackets, basic tumor types, sites of origin and clinical manifestations. In children carcinoma are exceedingly uncommon. Most of the tumors are embryonal in origin and teratoma make up the bulk of the remaining neoplasms. Abdominal tumors are usually silent until they have assumed tremendous size. Early detection and aggressive philosophy of management became important as the trend to cure with radiation and chemotherapy increased. In a child with an abdominal mass x-ray exams are useful and often diagnostic. The 92 cases of abdominal masses in infants and children under the age of 16, who had been treated at Severance Hospital for the duration of 14 years from 1960 to 1973 were reviewed in respect to their basic type of tumors, site of origin, age incidence as well as radiographic findings. The results may be briefly summarized as follows; 1. The commonest tumor was ovarian cyst being 25 cases which were largely encountered over the age of 12. The next common tumors were Wilms' tumor, 17 cases, hepatoma, 9 cases, neuroblastoma and hydronephrosis, 8 cases each, teratoma 6 cases, etc. 2. The retroperitoneal space including kidneys were the most commonly involved site (43.5%), of which Wilms' tumor was the commonest. 3. About 2/3 of tumors developed under the age of 6 and the commonest lesions was Wilms' tumor and the next being neuroblastoma, teratoma, ovarian cyst and so forth. 4.In all tumors except ovarian tumors and choledochal cyst, male was more frequently affected. 5. In plain abdominal 75% of neuroblastoma crossed the mid line while in Wilms' tumor only 2 cases (14%) showed midline cross. Calcific density was present in all 6 cases of teratoma (100%) as dense and discrete ossification, in 3 cases of neuroblastoma (38%) characteristically in diffuse stippled appearance and in one case of Wilms' tumor (6%), in which calcification was nonspecific. 9

    AIM: To retrospectively evaluate the computed tomography (CT)/magnetic resonance imaging (MRI) imaging features of epithelioid angiomyolipoma of the liver (Epi-HAML), with pathology as a reference. METHODS: The CT/MRI findings (number, diameter,lobar location, and appearance of lesions) in a series of 10 patients with 12 pathologically proven epithelioid angiomyolipomas of the liver were retrospectively analyzed. The imaging features, including attenuation/signal intensity characteristics, presence of fat,hypervascular, outer rim, and vessels within lesion,were evaluated and compared with that of non-Epi-HAML in 11 patients (13 lesions). The Fisher exact test was used to compare difference in probability of imaging features between the two types.RESULTS: For 21 patients, CT images of 15 patients and MR images of six patients were available. No patient underwent two examinations. For the 15 patients with a CT scan, all HAML lesions in the two groups (10 Epi-HAML and seven non-Epi-HAML) manifested as hypoattenuation. For the six patients with MRI, all lesions (two Epi-HAML and six non-Epi-HAML) were hypointense on T1WI (fat suppression) and hyperintense on T2WI. There were 10 non-Epi-HAML,but only two Epi-HAML lesions showed the presence of fat, which significantly different between the two types (P = 0.005). On the dynamic contrast enhancement (DCE) imaging, eight Epi-HAML, and 13 non-Epi lesions manifested as hypervascular. Punctate or curved vessels were displayed in 10 Epi-HAML as well as in nine non-Epi lesions and outer rim enhancement could be found with eight Epi-HAML as well as six non-Epi lesions.CONCLUSION: Little or no presence of adipose tissue was found to be an imaging feature of Epi-HAML, compared with the non-Epi type. In addition,hypervascularity with opacification of central punctiform or filiform vessels on DCE would be a characteristic enhancement pattern for Epi-HAML.

    Objective. The purpose of the study was to evaluate the appearance of ``cubital bursitis`` on ultrasonography and CT and MR imaging. ``Cubital bursitis`` is a rare pathological condition involving a large swelling of the bicipito-radial or interosseous bursae located at the insertion of the distal biceps tendon on the radial tuberosity. Design and patients. We report on five patients with ``cubital bursitis`` resulting from their work or sporting activities. All patients underwent an ultrasound and MR examination. CT scans were performed on two patients before and after contrast enhancement. Results. Ultrasound studies showed a fusiform anechoic or hypoechoic lesion. CT images showed the lesions but there were some difficulties in determining the exact extent of the bursae. MR imaging showed the enlarged bursae and their fluid content. Four patients each underwent a surgical procedure. Conclusion. Ultrasound and CT were effective in the evaluation of ``cubital bursitis``, but with some diagnostic difficulties. MR imaging is probably the method of choice for determining both the development of the bursae and their fluid content. (orig.)

    Highlights: •Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). •In this study, twenty-two of the thirty sudden infant death cases showed increasing concentration in the entire lung field. •Based on the autopsy results, the lungs simply collapsed and no other abnormal lung findings were identified. •The radiologist should not consider increasing concentration in all lung fields as simply a pulmonary disorder when diagnosing the cause of infant death using PMCT. -- Abstract: Objectives: Infant cases frequently show a diffuse increase in the concentration of lung fields on post-mortem computed tomography (PMCT). However, the lungs often show simply atelectasis at autopsy in the absence of any other abnormal changes. Thus, we retrospectively reviewed the PMCT findings of lungs following sudden infant death and correlated them with the autopsy results. Materials and methods: We retrospectively reviewed infant cases (0 year) who had undergone PMCT and a forensic autopsy at our institution between May 2009 and June 2013. Lung opacities were classified according to their type; consolidation, ground-glass opacity and mixed, as well as distribution; bilateral diffuse and areas of sparing. Statistical analysis was performed to assess the relationships among lung opacities, causes of death and resuscitation attempt. Results: Thirty infant cases were selected, which included 22 sudden and unexplained deaths and 8 other causes of death. Resuscitation was attempted in 22 of 30 cases. Bilateral diffuse opacities were observed in 21 of the 30 cases. Of the 21 cases, 18 were sudden and unexplained deaths. Areas of sparing were observed in 4 sudden and unexplained deaths and 5 other causes of death. Distribution of opacities was not significantly associated with causes of death or resuscitation attempt. The 21 cases with bilateral diffuse opacities included 6 consolidations (4 sudden and unexplained

    Background A gender-based disparity in physical activity (PA) among youth, whereby girls are less active than boys is a persistent finding in the literature. A greater understanding of the mechanisms underlying this difference has potential to guide PA intervention strategies. Methods Data were collected at age 8 and 12 years (276 boys, 279 girls) from 29 schools as part of the LOOK study. Multilevel linear models were fitted separately for boys and girls to examine effects of individual, family and environmental level correlates on pedometer measured PA. Cardio-respiratory fitness (multi-stage run), percent fat (DEXA), eye-hand coordination (throw and catch test) and perceived competence in physical education (questionnaire) were used as individual level correlates. At the family level, parent’s support and education (questionnaire) were used. School attended and extracurricular sport participation were included as environmental level correlates. Results Girls were 19% less active than boys (9420 vs 11360 steps/day, p<0.001, 95%CI [1844, 2626]). Lower PA among girls was associated with weaker influences at the school and family levels and through lower participation in extracurricular sport. School attended explained some of the variation in boys PA (8.4%) but not girls. Girls compared to boys had less favourable individual attributes associated with PA at age 8 years, including 18% lower cardio-respiratory fitness (3.5 vs 4.2, p<0.001, CI [0.5,0.9]), 44% lower eye-hand coordination (11.0 vs 17.3, p<0.001, CI [5.1,9.0]), higher percent body fat (28% vs 23%, p<0.001, CI [3.5,5.7]) and 9% lower perceived competence in physical education (7.7 vs 8.4, p<0.001, CI [0.2,0.9]). Participation in extracurricular sport at either age 8 or 12 years was protective against declines in PA over time among boys but not girls. Conclusion Girls PA was less favourably influenced by socio-ecological factors at the individual, family, school and environmental levels. These factors

    A pattern of abnormal signal at fetal MRI may be seen in the setting of primary or secondary congenital lymphangiectasia, manifested as a heterogeneous appearance of the lung parenchyma and the presence of subtle T2-hyperintense branching tubular structures that emanate from the hila. We have named this pattern the nutmeg lung. We describe the nutmeg lung appearance seen in fetal MRI scans, with discussion of possible etiologies and outcomes in a series of eight fetuses. We retrospectively reviewed imaging from a database of patients demonstrating features of nutmeg lung on fetal MRI. Medical records were used to determine the postnatal diagnosis, clinical course and outcome. Among the eight fetal cases of nutmeg lung, two had postnatal confirmation of primary lymphangiectasia and the remaining six had secondary lymphangiectasia, presumably secondary to congenital cardiac anomalies. There were various-size pleural effusions in all cases. Only one of the cases demonstrated hydrops fetalis. We present the description of the nutmeg lung sign on fetal MRI as T2-hyperintense heterogeneous lungs with fluid-filled, serpiginous branching structures that extend from the pulmonary hila to the periphery of the lung, often accompanied by pleural effusions. The sign denotes findings of primary or secondary lymphangiectasia. Findings of secondary lymphangiectasia in our series were a result of cardiac insufficiency. Recognizing this sign might be helpful in the diagnostic algorithm of the fetus with abnormal lung parenchyma. (orig.)

    To describe findings of patients with surgically confirmed pericardial disease on state of the art MR sequences. Retrospective review was performed for patients who underwent pericardiectomy and preoperative MR over a 5 year period ending in 2009. Patients' records were reviewed to confirm the diagnosis of chronic recurrent pericarditis, constrictive pericarditis, or pericardial tumor. MR imaging findings of pericardial thickness, IVC diameter, presence or absence of pericardial or pleural effusion, pericardial edema, pericardial enhancement, and septal "bounce" were recorded. Patients with constriction had a larger IVC diameter (3.1 ± 0.4 cm) than patients with recurrent pain and no constriction (2.0 ± 0.4 cm). Mean pericardial thickness for the 16 patients with chronic recurrent pericarditis but no evidence of constriction was 4.8 ± 2.9 mm. Mean pericardial thickness for patients with constriction was 9.2 ± 7.0 cm with calcification, and 4.6 ± 2.1 cm without calcification. 94% of patients with chronic recurrent pericarditis had gadolinium enhancement of the pericardium, while 76% of patients with constriction had pericardial enhancement. Septal "bounce" was present in 19% of chronic recurrent pericarditis cases and 86% of constriction cases. 5 patients had a pericardial neoplasm, 1 of which was not identified preoperatively. State of the art MR techniques can identify significant and distinct findings in patients with chronic recurrent pericarditis, constrictive pericarditis, and pericardial tumors. PMID:21735292

    Malignant pleural mesothelioma is an uncommon neoplasm which is accompanied extremely rarely by osteoblastic heterologous elements. The CT manifestations of this tumor have been reported in several references. And, to our knowledge, only one case report provides a description of the bone scan findings. Here, we report the case of a rapidly progressing malignant pleural mesothelioma with heterologous osteoblastic elements. A CT scan reveals diffuse irregular pleural thickening and very coarse nodular calcifications along the right pleura and major fissure. A bone scan revealed an area of extensive increased radioactivity consistent with the pleural calcifications on the CT scan in the right hemithorax. A follow-up CT scan performed 40 days later suggests the presence of rapidly progressing nodular coarse calcifications.

    We report a rare case of a 45-year-old African American woman with Neuroblastoma-like Schwannoma (Neurilemmoma) occurring in the posterior mediastinum as a pleural-based mass noted on computed tomography (CT) scan. A CT-guided core biopsy of the mass was performed and core biopsy imprints were prepared during the procedure. A Diff-Quik stain was performed for on-site evaluation of specimen adequacy. The hematoxylin and eosin (H&E) staining was evaluated subsequently. Immunohistochemistry panels were applied to the same specimen. The cytologic findings of the core biopsy imprints showed hypercellular smears with a predominance of small cells with atypical features including hyperchromatic, round nuclei and occasional nucleoli. Neurocytic rosettes were particularly appreciated on H&E stain. The immunohistochemical results exhibited strong and diffuse immunoreactivity for S-100 and vimentin. This case enriches the cytopathology literature by providing awareness of this tumor presenting as a posterior mediastinal mass.

    In this report, we present a rare case of primary signet-ring cell carcinoma of the appendix in a 51-year-old woman with right lower quadrant pain. Since non-specific concentric appendiceal wall thickening was found in a radiologic evaluation, it was misdiagnosed as non-tumorous appendicitis. An in-depth examination of the correlation between sonographic and histopathologic findings demonstrated that a single markedly thickened hypoechoic layer was well correlated with the diffuse infiltration of tumor cells in both the submucosal and muscle layers. If this sonographic finding is observed in certain clinical settings, such as potential ovarian and peritoneal metastasis, submucosal infiltrative tumors, including signet-ring cell carcinoma, should be considered in the differential diagnosis.

The answer to this question lies in the field of public policy implementation, an area studied in a discontinuous manner over time. After a theoretical account, this article explores - starting from an instrumental case set in a Mexican subnational government which has implied bringing a legislative decision related to transparency to reality. Among the findings it is prominent situations of a political nature, agreements between groups and concentration of power in few actors, for example, as contributing elements to the gap between what was planned and executed.

    Full Text Available Abstract Background In the primary care setting, dementia is often diagnosed relatively late in the disease process. Case finding and proactive collaborative care may have beneficial effects on both patient and informal caregiver by clarifying the cause of cognitive decline and changed behaviour and by enabling support, care planning and access to services. We aim to improve the recognition and diagnosis of individuals with dementia in general practice. In addition to this diagnostic aim, the effects of case finding and subsequent care on the mental health of individuals with dementia and the mental health of their informal carers are explored. Methods and design Design: cluster randomised controlled trial with process evaluation. Participants: 162 individuals ≥ 65 years, in 15 primary care practices, in whom GPs suspect cognitive impairment, but without a dementia diagnosis. Intervention; case finding and collaborative care: 2 trained practice nurses (PNs invite all patients with suspected cognitive impairment for a brief functional and cognitive screening. If the cognitive tests are supportive of cognitive impairment, individuals are referred to their GP for further evaluation. If dementia is diagnosed, a comprehensive geriatric assessment takes place to identify other relevant geriatric problems that need to be addressed. Furthermore, the team of GP and PN provide information and support. Control: GPs provide care and diagnosis as usual. Main study parameters: after 12 months both groups are compared on: 1 incident dementia (and MCI diagnoses and 2 patient and caregiver quality of life (QoL-AD; EQ5D and mental health (MH5; GHQ 12 and caregiver competence to care (SSCQ. The process evaluation concerns facilitating and impeding factors to the implementation of this intervention. These factors are assessed on the care provider level, the care recipient level and on the organisational level. Discussion This study will provide insight

    Hallervorden-Spatz syndrome is a neuro degenerative disease, autosomic recessive with two clinical features: early and late onset. Psychiatric, pyramidal and extrapyramidal signs are present in the late subtype. We report the case of a 41-old woman with extrapyramidal signs. Magnetic resonance imaging (MRI) showed the eye-of-the-tiger sign in the medial globus pallidus. This is due to a gliosis (increased signal) and accumulation of surrounding iron (decreased signal intensity) in long T R sequences. There is a strong relationship between MRI findings and the gene mutation responsible for this disease. It makes the MRI sensible for diagnosing this syndrome. (author)

    Incomplete history and concern for occult injury in suspected child abuse occasionally results in CT screenings of the abdomen and pelvis. At our institution, we noted that these exams were infrequently positive. To identify clinical or laboratory criteria that may predict intra-abdominal injury and guide the use of abdominal and pelvic CT in this population. This retrospective review involved 68 children older than 36 months who had a CT of the abdomen/pelvis for suspected abuse. CT results and patient charts were reviewed for physical exam and historical and laboratory variables. CTs were positive in 16% of patients (11/68). Hypoactive/absent bowel sounds (P = 0.01, specificity = 94.7%) and AST and ALT values greater than twice normal (P = 0.004 and P = 0.003 respectively, NPV = 93.6%) were significantly associated with positive CTs. Multiple abnormal physical exam or laboratory findings were also significantly associated with positive CTs (P = 0.03 and P = 0.002 respectively, specificity = 91.3% and NPV = 93.6% respectively). CTs of the abdomen and pelvis are infrequently positive in cases of suspected abuse. To reduce radiation exposure, CTs should only be ordered if there are findings indicating that they may be positive. In our population, these findings include absent/hypoactive bowel sounds, LFTs greater than twice normal and {>=}2 abnormal labs or physical exam findings. (orig.)

    Full Text Available Abstract Background Increased detection of tuberculosis (TB using intensified or active case finding (ICF is one of the cornerstones of the Stop TB Strategy, and contrasts with passive case finding (PCF which relies on self-reported symptoms. There is no clear guidance on implementation strategies. We implemented ICF in addition to ongoing PCF in our large urban HIV clinic in July 2010 using a twice-daily announcement screen method by a trained peer educator, asking waiting patients to self-refer to a trained peer supporter for screening of TB symptoms. We sought to determine the associated effect on TB case detection. Methods Suspects were investigated by sputum smear, chest X-ray and ultrasound, if indicated. Routinely collected clinical and laboratory data were merged with the ICF register and TB clinic data for patients attending the clinic in 2010. We compared the yield of TB cases (defined as the prevalence of newly diagnosed TB cases in the screened population, the type of TB diagnosed and the total cost per TB case identified (in United States Dollars [USD] for the period before and after ICF implementation. Results Of the 20,456 patients who visited the clinic in 2010, 614 were identified as TB suspects, 220 pre-ICF and 394 post-ICF (229 via PCF and 165 via ICF. The proportion diagnosed with TB dropped from 66% to 48% (60% in suspects identified through PCF and 31% through ICF. During the post-ICF period, TB suspects identified through ICF compared to PCF identification were more likely to be female, older, on ART and to have been enrolled in HIV care for a longer duration. The yield of combined PCF and ICF screening was 1.4% pre-ICF and 1.7% post-ICF with a cost per TB case identified of 12.29 USD and 21.80 USD, respectively. Conclusions Implementation of ICF in a large HIV clinic yielded more TB suspects and cases, but substantially increased costs and was unable to capture the majority of TB suspects who were referred for diagnosis

    A 71-year-old male was admitted to Kohka Public Hospital on January 4, 1980, because of frequent vomiting and recent memory loss. Two weeks before admission upper G-I series showed no abnormalities. Physical and neurological examinations revealed no abnormalities except for slightly apathetic appearance and recent memory loss. Mild pleocytosis and marked increase of protein in CSF were observed. CT scan on January 17 showed high density areas in both medial sides of temporal lobes with remarkable contrast enhancement. His memory and, consciousness disturbances gradually aggravated, accompanied by abnormal density spreading around the ventricle walls like ventriculitis. He was transfered to Kyoto University Hospital on March 17, and malignant lymphoma was diagnosed on the basis of CSF cytology. Radiation and chemotherapy alleviated the CNS involvement and he regained normal mental function. On June 16, he developed pneumonia followed by status epilepticus. Autopsy findings revealed no lymphoid cell infiltration, but fibrous tissues in both hippocampal gyri and lymphomatous cells in the liver, which could not be suspected on clinical examinations. Apparent malignant lymphoma cells were not found in lymph nodes. This case indicated peculiar evolution of malignant lymphoma from liver to CNS or vice versa. We could not decide which organ was primary. CT findings of this case was very interesting; they resembled ventriculitis, which simulate tumors such as medulloblastoma or ependymoma spreading under ependymal lining.

    We report a rare case of CNS vasculitis associated with Goodpasture's syndrome in a 34-year-old man, who presented with a seizure and sudden onset of right sided weakness. He also had recurrent hemoptysis of one month's duration. Goodpasture's syndrome is histologically diagnosed by intense linear deposits of IgG along the glomerular basement membrane in both renal and lung tissues. oodpasture's syndrome is a rare disease, characterized by rapidly progressive glomerulonephritis, diffuse pulmonary hemorrhage and circulating antiglomerular basement membrane antibody (anti-GBM antibody). Central nervous system (CNS) manifestations in Goodpasture's syndrome are extremely rare, with only a few cases having been reported in the literature (8 10). Therefore, we present our imaging findings of CNS vasculitis associated with Goodpasture's syndrome, together with a review of the relevant literature. In summary, CNS vasculitis associated with Goodpasture's syndrome is extremely rare. Awareness of the imaging findings, as well as the clinical significance of CNS vasculitis associated with Goodpasture's syndrome, can be helpful in making the correct diagnosis and subsequent management of this rare condition.

    AIM: To evaluate the effectiveness of a rapid and easy fingertip whole blood point-of-care test for celiac disease (CD) case finding and diet monitoring.METHODS: Three hundred individuals, 206 females (68.7%) and 94 males (31.3%), were submitted to a rapid and easy immunoglobulin-A-class fingertip whole blood point-of-care test in the doctor's office in order to make immediate clinical decisions: 13 healthy controls, 6 with CD suspicion, 46 treated celiacs, 84 relatives of the celiac patients, 69 patients with dyspepsia, 64 with irritable bowel syndrome (IBS), 8 with Crohn's disease and 9 with other causes of diarrhea.RESULTS: Upper gastrointestinal endoscopy with duodenal biopsies was performed in patients with CD suspicion and in individuals with positive test outcome: in 83.3% (5/6) of the patients with CD suspicion, in 100% of the patients that admitted gluten-free diet transgressions (6/6), in 3.8% of first-degree relatives (3/79) and in 2.9% of patients with dyspepsia (2/69). In all these individuals duodenal biopsies confirmed CD (Marsh's histological classification). The studied test showed good correlation with serologic antibodies, endoscopic and histological findings.CONCLUSION: The point-of-care test was as reliable as conventional serological tests in detecting CD cases and in CD diet monitoring.

    2012-02-01

    AIM: To identify the risk factors for, and to report the microbiological findings and clinical outcomes of, severe microbial keratitis (MK). METHODS: This was a retrospective study of all cases of presumed MK admitted to a tertiary referral center over a 2-year period (September 2001 to August 2003). Data recorded included demographic data, details relating to possible risk factors, results of microbiological studies, clinical findings at presentation, and clinical and visual outcomes. RESULTS: Ninety patients were admitted with a diagnosis of presumed MK during the study period. The mean age of patients was 45 +\\/- 32 years, and the male to female ratio was 47:43 (52.2%:47.7%). Predisposing risk factors for MK included contact lens wear (37; 41.1%), anterior segment disease (19; 21.1%), ocular trauma (13; 14.4%), systemic disease (5; 5.6%), and previous ocular surgery (1; 1.1%). Cultured organisms included gram-negative bacteria (17; 51.5%), gram-positive bacteria (11, 33.3%), acanthamoeba (2; 6.1%), and fungi (1; 3%). Visual acuity improved significantly after treatment [mean best-corrected visual acuity (+\\/-standard deviation) at presentation: 0.76 (+\\/-0.11); mean best-corrected visual acuity at last follow-up: 0.24 (+\\/-0.07); P < 0.001]. Secondary surgical procedures were required in 18 (20%) cases, and these included punctal cautery (1; 1.1%), tissue glue repair of corneal perforation (2; 2.2%), tarsorrhaphy (9; 9.9%), Botulinum toxin-induced ptosis (1; 1.1%), penetrating keratoplasty (3; 3.3%), and evisceration (2; 2.2%). CONCLUSIONS: Contact lens wear remains a significant risk factor for severe MK. MK remains a threat to vision and to the eye, but the majority of cases respond to prompt and appropriate antimicrobial therapy.

  7. Three rounds as "tandem bullets": unusual findings in a case of a suicidal gunshot to the head.

    We report an unusual case of suicide in which three 7.65 caliber projectiles were found in the single gunshot wound to the head of a 53-year-old man. Based on data collected at the death scene, CT scan, autopsy findings, and ballistics analysis, the events were reconstructed as follows: two 7.65 mm rounds had already been fired from the 9 mm Makarov pistol the subject was using but, being a smaller caliber, the cartridges had slipped forward and lodged within the barrel. When a third 7.65 mm cartridge was chambered and the gun fired for the third time, the nose of the last bullet hit the lodged bullets and all three rounds were propelled out of the muzzle in tandem as a single shot. Ballistic investigations confirmed that the kinetic energy of the three tandem bullets would have been sufficient to perforate the skull. In cases of gunshot wounds where the manner of death is unclear, a number of well-described circumstantial parameters, such as an atypical anatomical location of the gunshot, unusual firearm, or ammunition, as well as ambiguous autopsy findings, can raise doubts about the manner of death. In very rare cases, despite a single entrance wound, two or more bullets are recovered from the body, fired by the same weapon at the same time (the so-called "tandem bullet" phenomenon). Injuries by "tandem bullets" have crucial implications in gunshot deaths because of the mismatch between the number of entrance and exit wounds and the number of bullets found in or near the body.

    We report the quantification of immunohistochemical findings for a diagnosis of dementia in autopsy cases among older decedents. Autopsy cases were selected with the following requirements: >65yo; no head injuries, thermal injuries, or heat stroke; no intracranial lesions; and within 48h of death. Among cases that met all requirements, 10 had a clinical diagnosis of dementia were included in dementia group. Non-dementia group consisted of 38 cases without any record of dementia. To compare these groups, immunohistochemically, beta-amyloid, tau protein, gephyrin, and IL-33 were examined in five regions. Quantitative analysis was performed by collecting with image data analyzed using analysis software. Image data on tau-immunopositive neurofibrillary tangles (NFT) and beta-amyloid-positive senile plaques (SP) were photographed. Criteria for dementia were made by counting and measuring NFT and SP from image data using software. Differences in SP and NFT were effective for discriminating between the two groups. These criteria may reveal the presence and progression of dementia. Total of tau-positive NFT in Ammon's horn (AH) may be useful for diagnosing dementia. When the total is more than 41 in approximately 6mm(2) of AH, the possibility of dementia is considered. Total of beta-amyloid-positive SP in the parahippocampal gyrus (PHG) may be useful for diagnosing dementia. When the total in approximately 5mm(2) of PHG is more than 47, the possibility of dementia is considered. Immunohistochemical staining may be more useful for obtaining image data for quantification than conventional staining techniques, such as Bielschowsky-Hirano's silver staining. PMID:27591545

    2012-10-01

    Full Text Available Abstract Background A pilot project cardiovascular prevention was implemented in Sandwell (West Midlands, UK. This used electronic primary care records to identify untreated patients at high risk of cardiovascular disease then invited these high risk patients for assessment by a nurse in their own general practice. Those found to be eligible for treatment were offered treatment. During the pilot a higher proportion of high risk patients were started on treatment in the intervention practices than in control practices. Following the apparent success of the prevention project, it was intended to extend the service to all practices across the Sandwell area. However the pilot project was not a robust evaluation. There was a need for an efficient evaluation that would not disrupt the planned rollout of the project. Methods/design Project nurses will sequentially implement targeted cardiovascular case finding in a phased way across all general practices, with the sequence of general practices determined randomly. This is a stepped wedge randomised controlled trial design. The target population is patients aged 35 to 74, without diabetes or cardiovascular disease whose ten-year cardiovascular risk, (determined from data in their electronic records is ≥20%. The primary outcome is the number of high risk patients started on treatment, because these data could be efficiently obtained from electronic primary care records. From this we can determine the effects of the case finding programme on the proportion of high risk patients started on treatment in practices before and after implementation of targeted case finding. Cost-effectiveness will be modelled from the predicted effects of treatments on cardiovascular events and associated health service costs. Alongside the implementation it is intended to interview clinical staff and patients who participated in the programme in order to determine acceptability to patients and clinicians. Practical

    2014-06-01

    Full Text Available Perinephric peripelvic lymphangiomatosis is a rare benign malformation of lymphatic system; that may be confused with various forms of renal cystic diseases and urinomas. In this disorder a developmental malformation results in failure of developing lymphatic channels to establish normal communication with the rest of lymphatic systems and restrict/ failure drainage of lymphatic fluid, dilate the channels to form cystic masses that may be unilocular or multilocular and may be seen unilaterally or bilaterally. This condition presents with various signs and symptoms or can be just incidental findings which in presence of misleading clinical history may be confused with other diseases. Definitive diagnosis is possible with USG and CT scan. Here we report a case of bilateral perirenal and peripelvic involvement with a normal excretory function

    Gastric volvulus, defined as an abnormal rotation of stomach, may be idiopathic or secondary to abnormal fixation of intraperitoneal visceral ligaments. Wandering spleen is a movable spleen resulting from absence or underdevelopment of the splenic supporting ligaments that suspend the spleen to its normal position in the left part of the supramesocolic compartment of the abdomen. Wandering spleen increases the risk of splenic torsion. Both gastric volvulus and splenic torsion are potentially life-threatening if not urgently managed with surgery. Prompt and accurate diagnosis based on multidetector computed tomography (MDCT) is crucial to prevent unforeseen complications. Gastric volvulus and coexistent torsion of wandering spleen is a very rare condition. Herein, we described a case of gastric volvulus associated with wandering spleen and intestinal non-rotation in a 15-year-old girl focusing on MDCT findings.

  18. Do X-ray diagnosis and endoscopic findings agree in the case of Ulcus ventriculi and Ulcus duodeni?

    International Nuclear Information System (INIS)

    The goal of this work is a correlation of the radiological and endoscopic findings of a university clinic in cases of stomach and duodenal ulcers. The sensitivity of the radiological examinations with Ulcus ventriculi, respectively duodeni, was 89%, respectively 91%; the specificity was 74%, respectively 85%. From these results suggestions were made for the use of endoscopy with radiologically diagnosed ulcers of the duodenum or stomach. Whereas the endoscopy is superior for the recognition of florid ulcers in a deformed Bulbus duodeni, radiology is superior in determining sinus developments, stenotic areas and the extent of an evacuation disturbance. A proper diagnosis is made possible by a purposeful combination of radiological and endoscopic-bioptic methods. (TRV)

    Osteopoikilosis is a benign but rare condition characterized by bone islands throughout the osseous tissue, which could be easily confused with bone metastasis. We present a case of a 37-year-old man presented to orthopedic outpatient clinic with right hip pain for 2 weeks. There were multiple, small punctate lesions scattered throughout the skeleton on radiograph. Subsequent Tc-99m methylene diphosphonate (MDP) bone scan with pelvic single-photon emission computed tomography (SPECT)/computed tomography (CT) showed multiple enostoses without abnormal focal MDP uptake. Therefore, clinical diagnosis was compatible with osteopoikilosis while bone metastasis was unlikely. The symptoms then improved by conservative treatments. Osteopoikilosis is usually an incidental finding on radiograph or CT, and a normal MDP confirmed the diagnosis by excluding bone metastasis. It is important for clinicians to recognize the specific image features to prevent further unnecessary interventions. In addition, bone SPECT/CT could also make the diagnosis in one step.

    1998-10-01

    Hyalinizing trabecular adenoma is a recently described benign thyroid tumor, almost exclusively occurring in females. The morphological features of this entity overlap with both papillary and medullary carcinoma to varying extent. This, in turn, creates a situation of serious diagnostic pitfall particularly for a false positive diagnosis of papillary carcinoma in fine needle aspiration (FNA) cytology. False consideration of medullary carcinoma is also possible by the unwary especially if staining for Congo red and/or immunostaining for calcitonin is not resorted to. At histologic level, the distinctive architectural pattern is however of great help and thus poses a much lesser danger of misdiagnosis. We relate here our experience in a recently encountered case of hyalinizing trabecular adenoma and describe detailed FNA cytologic and histologic findings along with immunohistochemical profile using a panel of eight monoclonal antibodies. The tumor proliferative potential has also been assessed using MIB-1 (Ki-67) immunostaining. The various pros and cons of diagnostic pitfalls are discussed. PMID:9866913

  1. The radiological findings of pulmonary tuberculosis: the analysis of 117 cases in Nagquka, tibet (with the comparison of 109 cases in Zhanjiang, Guangdong)

    International Nuclear Information System (INIS)

    Objective: It is an investigation of the characteristic radiological findings of pulmonary tuberculosis in population of Nagquka, northern Tibet. Method: During July, 1996 to September, 1999, the initial chest film (CXR) of 117 cases of pulmonary tuberculosis from Nagquka, were compared with the CXR of 109 cases encountered in sea-side city Zhanjiang, with the same constituent ratio of age. According to the classification system for pulmonary tuberculosis of 1998, double-blinded investigation was made on the two groups and (x2 test was applied for statistical analysis. Results: Higher rate (7.69%) of primary pulmonary tuberculosis with higher ratio of adult patients were revealed in Nagquka group, while high rate (93.6%) of secondary pulmonary tuberculosis was found in the control group. More cases (16.2%) presented segmental consolidation in Nagquka group than that in control group, while in most of cases (74.3%) of control group, small patchy lesions were the predominant pattern. In 31.6% cases of the research group, 4 or more lung fields were involved, while in the control group the ratio was 16.5%. More rare locations of the lesion, like inferior lung field were revealed in the research group, and the ratio of rare location was 12.8% in research group and 0.9% in the control group. The rate of cavity (11.97%) was not high in research group, but 32.1% in control group. Statistical significance was indicated (P 2 test. Conclusion: For the radiological manifestations of pulmonary tuberculosis, there are significant differences between the population of Nagquka and the sea-side city Zhanjiang

Case 1: A 35-year-old male patient had progressive stiffness of lower limbs of 13 years and generalized muscle hypertrophy and myalgia of 3 years duration. Had periorbital edema, dry skin, generalized muscle hypertrophy and spastic dysarthria with hoarseness. Muscle power was normal. Jaw jerk and deep tendon reflexes were exaggerated. Case 2: A 24-year-old male patient presented with muscle hypertrophy from childhood, slowness in motor activities and hearing impairment. For 6 months, he had severe muscle pains, cramps and further increase in hypertrophy. He had yellow tinged, dry skin, hoarseness of voice, gross muscle hypertrophy and minimal weakness. Both had markedly elevated serum creatine kinase (CK) levels and high thyroid stimulating hormone, low free triiodothyronine and free thyroxine levels. Levothyroxine treatment demonstrated remarkable reduction in muscle bulk at 2 months in both and no symptoms at 6 months. Magnetic resonance imaging of lower limbs in both cases revealed almost identical features with involvement of the muscles of posterior and adductor compartment of thighs and posterior and lateral compartments of the legs. Differential diagnosis of long duration muscle pseudohypertrophy and elevated CK levels should include HS. PMID:25024579

    Full Text Available The reign of Queen Cleopatra VII of Egypt offers a rare historical glimpse into ancient communication activities and how communication was used by the world’s last pharaoh. This historical research reveals how Cleopatra used public relations and strategic communication activities to advance both her reign as a lone woman sovereign and the interests of the Egyptian empire. Cleopatra was perhaps the first woman sovereign in history to rule alone for a period of over a decade. Her leadership showed skilled use of public communication and diplomacy with which she forestalled the fall of Egypt to Rome. A grounded theory approach allowed data to emerge naturally, surrounding communication activities, and then for a theoretical framework to be imposed that could explain the common themes in that data. This research compares Cleopatra’s activities with public relations theory using the classic four models of public relations to classify public communication. Findings show that Cleopatra used research in asymmetrical public relations and symmetrical relationship building, also including public diplomacy, public information, and press agentry/pseudo-event mastery. Careful examination of literature sources led to the conclusion that Cleopatra was a truly advanced, research-based, relationship-focused, and international policy-oriented lone woman ruler who was a supremely strategic communicator.

    This is the case of a previously healthy, 11-year-old male of Indian descent who presented to the emergency department with a 2-month history of nausea, vomiting, diarrhea, fatigue, cough, and 7-lb weight loss. Acutely, he developed 5 days of fever as high as 39.4°C. He had a remote travel history to the Middle East. On physical examination, he was febrile and tachycardic, was thin but otherwise had a normal examination. His inflammatory markers were elevated: erythrocyte sedimentation rate was 93 mm/hour and his C-reactive protein was 25.4 mg/L. A complete blood count revealed a white blood cell count of 17,000 × 10(3)/µL with increased bands. His hemoglobin level was 8.8 g/dL with a mean corpuscular volume of 81 fl. Platelets were 556 × 10(3)/µL. A chest radiograph was concerning for a cavitary lung lesion and an abdominal ultrasound revealed multiple hypoechoic lesions in his spleen. Our panel of experts reviews his case and examines the workup of this patient with diverse symptoms and focal findings on chest radiograph and abdominal ultrasound. PMID:26908705

    Full Text Available Spinal cord infarction (SCI often remains undiagnosed due to infrequent occurrence and lack of established diagnostic procedures. The unique pattern of blood supply explains the heterogeneity of clinical presentation. We present three cases of SCI to highlight the varied spectrum of clinicoradiological findings. The first patient had posterior spinal artery infarction, and spine imaging showed infarction of adjacent vertebral body, which is usually rare. The second patient had anterior spinal artery infarction and the cANCA titers were elevated. The third patient had a pure motor quadriparesis. Initial imaging did not show any cord infarction, but signal changes were noted on serial imaging. Fibrocartilagenous embolism (FCE seems the most likely etiology in the first and third cases. A high index of clinical suspicion is necessary for prompt diagnosis. Sensitivity of the initial magnetic resonance imaging remains limited, necessitating serial follow-up scans. Infarction of the adjacent vertebral body is a useful confirmatory sign. Fat suppression images can delineate the marrow signal changes better. Elderly patients with vascular risk factors and degenerative discs need to avoid mechanical triggers that predispose to FCE. Younger patients with SCI will need evaluation for cardioembolic source and vasculitis.

    Full Text Available Abstract Introduction Composite tumors of the adrenal medulla or paraganglia are extremely rare and present a diagnostic dilemma. These tumors consist of a neuroendocrine component mixed with a neural component. We describe the imaging characteristics together with the corresponding pathological findings of a composite tumor. Apart from any component-specific imaging findings, the hallmark of this entity is the presence of histologically distinguishable components. Case presentation A 61-year-old Caucasian man was referred to our hospital due to a suspect lesion found on chest computed tomography carried out for unclear thoracic pain. An abdominal computed tomography scan and ultrasound examination detected a retroperitoneal tumor comprising two different tumor components. Twenty-four-hour urine revealed high levels of normetanephrine, characteristic of a neuroendocrine tumor. An octreoscan prior to surgical procedures revealed multiple osseous and intra-hepatic metastases. The final histopathological workup revealed a composite paraganglioma with neuroblastoma. Our patient died ten months after the initial diagnosis from tumor-associated complications. Conclusions Composite paragangliomas with neuroblastoma are rare tumors of the retroperitoneum. Such tumors should be considered in the differential diagnosis of retroperitoneal masses.

    Herlyn-Werner-Wunderlich (HWW) syndrome is a rare developmental anomaly that is consists of uterus didelphys with obstructed hemivagina and ipsilateral renal agenesis. This rare entity is the spectrum of Mullerian duct anomalies (MDA) accompanied by developmental anomaly of one of Wolffian ducts. The present report demonstrated HWW syndrome and reviewed literatures in term of embryological etiology, clinical manifestation, radiographic findings and surgical management. In this case report is a 11-year-old girl presented with chronic pelvic pain. She had menarche at the age of 10 and her menstrual cycles were regular with moderate dysmenorrhea. Physical examination revealed palpable pelvic mass with tenderness. Transabdominal ultrasonography (US) and Magnetic resonance imaging (MRI) demonstrated uterine didelphys with right-sided hematometrocolpos and absent right kidney. Right hematosalpinx was also detected due to distal tubal occlusion from adhesion. These preoperative images can verify all of the features of this syndrome and correctly anticipated diagnosis was achieved. The patient underwent laparoscopic right tubal drainage with lysis of pelvic adhesion and hysteroscopic resection of vaginal septum. Her symptoms were improved uneventfully. In conclusion, HWW syndrome exhibits unique clinical presentation with characteristic radiographic findings and symptom can be relieved dramatically after receiving appropriate surgical management.

    Few case-finding instruments are available to community healthcare professionals. This review aims to identify short, valid instruments that detect older community-dwellers risk of four adverse outcomes: hospitalisation, functional-decline, institutionalisation and death. Data sources included PubMed and the Cochrane library. Data on outcome measures, patient and instrument characteristics, and trial quality (using the Quality In Prognosis Studies [QUIPS] tool), were double-extracted for derivation-validation studies in community-dwelling older adults (>50 years). Forty-six publications, representing 23 unique instruments, were included. Only five were externally validated. Mean patient age range was 64.2-84.6 years. Most instruments n=18, (78%) were derived in North America from secondary analysis of survey data. The majority n=12, (52%), measured more than one outcome with hospitalisation and the Probability of Repeated Admission score the most studied outcome and instrument respectively. All instruments incorporated multiple predictors. Activities of daily living n=16, (70%), was included most often. Accuracy varied according to instruments and outcomes; area under the curve of 0.60-0.73 for hospitalisation, 0.63-0.78 for functional decline, 0.70-0.74 for institutionalisation and 0.56-0.82 for death. The QUIPS tool showed that 5\\/23 instruments had low potential for bias across all domains. This review highlights the present need to develop short, reliable, valid instruments to case-find older adults at risk in the community.

    Congestive heart failure is characterized by hemodynamic and non-hemodynamic abnormalities, the latter including an activation of the sympathetic influences to the heart and peripheral circulation coupled with an impairment of baroreceptor control of autonomic function. Evidence has been provided that both these alterations are hallmark features of the disease with a specific relevance for the disease progression as well as for the development of life-threatening cardiac arrhythmias. In addition, a number of studies have documented in heart failure the adverse prognostic role of the sympathetic and baroreflex alterations, which both are regarded as major independent determinants of cardiovascular morbidity and mortality. This represents the pathophysiological and clinical background for the use of carotid baroreceptor activation therapy in the treatment of congestive heart failure. Promising data collected in experimental animal models of heart failure have supported the recent performance of pilot small-scale clinical studies, aimed at providing initial information in this area. The results of these studies demonstrated the clinical safety and efficacy of the intervention which has been tested in large-scale clinical studies. The present paper will critically review the background and main results of the published studies designed at defining the clinical impact of baroreflex activation therapy in congestive heart failure patients. Emphasis will be given to the strengths and limitations of such studies, which represent the background for the ongoing clinical trials testing the long-term effects of the device in heart failure patients.

    Sapir, S; Larson, K K

    1993-09-01

    Four classically trained sopranos, aged 22-41 years, sustained a vibrato at a comfortable loudness level, and at different vowels (/u/, /i/, or /a/) and pitch levels (220, 277, 349, 440, 554, 698, or 880 Hz). Pairs of surface electrodes were placed on each singer's right side over the submandibular region, the thyroid cartilage, mandibular ramus, and upper lip to record electromyographic (EMG) activity from the anterior suprahyoid (ASH), extralaryngeal (ELAR), massetter (MAS), and perioral (PER) muscles, respectively. A headset-mounted miniature microphone transduced the voice, and a Kay Visi-Pitch extracted the voice fundamental frequency (F0). The output of the Visi-Pitch, a voltage analog of the F0 (VF0), and the EMG signals were digitized, the EMG signals rectified and smoothed, and the VF0 and smoothed EMG signals were subjected to Fast Fourier Transform (FFT) analysis. Spectral peaks in the FFT records indicated vibrato-related activity in the ASH and ELAR muscles, with occasional vibrato-related activity in the MAS and PER muscles. The role of supralaryngeal muscles in vibrato is discussed. PMID:8353638

    2010-04-01

    Several U.S. Government agencies promote energy efficiency in buildings internationally. The types and scope of activities vary by agency. Those with the largest role include the U.S. Agency for International Development (USAID), the U.S. Department of State and the Environmental Protection Agency (EPA). Both USAID and the Department of State have a substantial presence overseas, which may present some complementarities with the Department of Energy’s efforts to reach out to other countries. Generally speaking, USAID focuses on capacity building and policy issues; the Department of State focuses on broad diplomatic efforts and some targeted grants in support of these efforts, and EPA has more targeted roles linked to ENERGY STAR appliances and a few other activities. Several additional agencies are also involved in trade-related efforts to promote energy efficiency in buildings. These include the Department of Commerce, the Export-Import Bank, the Overseas Private Investment Corporation and the Trade and Development Agency (TDA). This initial synthesis report is designed to summarize broad trends and activities relating to international cooperation on energy efficiency in buildings, which can help the U.S. Department of Energy (DOE) in developing its own strategy in this area. The Pacific Northwest National Laboratory will develop a more complete synthesis report later in 2010 as it populates a database on international projects on building energy efficiency.

    Background: Menopause represents the end of women reproductive career and it is at this time they begin to manifest morbidities such as urinary incontinence. Aim: To document proximate determinants of sexual activity and urological morbidities of menopausal women. Subjects and Methods: This was a community survey conducted among 254 menopausal women Mokola in Ibadan, Nigeria in 2008. Respondents were selected using cluster sampling technique. Interviewer administered questionnaires were used to obtain information on their characteristics, pattern of urological and sexual activities. Descriptive, bivariate and multivariable tests were performed with Statistical Package for the Social Sciences 15.0 (Chicago, IL USA) and statistical significance was set at P value less than 0.05. Results: The mean age of subjects was 60.3 (standard deviation = 10.2 years). About 33.5% (85/254) was still sexually active. About 68% (173/254) reported a reduction in sexual frequency since menopause while 31.5% (80/254) reported no change. The mean self-rated sexual performance score was 4.3 based on a numerical scale where 10 is the maximum obtainable. Significant predictors of reduction in sexual activity were age at menopause and education. Those between 45 and 49 years were less likely than those at 55 years or more (odds ratio [OR] = 0.21; 95% confidence interval OR = 0.05-0.87) while women with at least secondary education were thrice less likely than those with none to report a reduction in sexual activity after menopause. Less than a tenth reported urinary incontinence as a complaint. Urge incontinence was the most commonly reported followed by dysuria and stress incontinence. Less than a quarter of them had requested for a form of treatment. Conclusion: Sexual performance of Nigerian menopausal women is associated with age at menopause and education. Non-fistulous urinary incontinence is now being mentioned as a complaint contrary to the widely held view that it is part of the

    Full Text Available Background Cultural awareness education is mandatory for medical programs, with particular emphasis on Aboriginal and Torres Strait Islander health. However, there is limited evidence to measure the impact of such education has on medical students. Aims This paper presents the development and delivery of a cultural immersion activity for first year undergraduate medical students. Additionally we explore how this type of activity may improve attitudes, comprehension and perceived competence relating to working with and understanding people of different cultures. Methods A pre- and post-survey design was utilised in connection with a cultural immersion activity. First year medical students (N=284, responses 196, 69 per cent from three cohorts (2012–2014 inclusive voluntarily completed a cultural awareness questionnaire, which contained items that related to perceptions, personal characteristics and educational competence. The main outcome measures were changes in perceived cultural knowledge, awareness, beliefs and attitudes. Data were analysed using principal component analysis and obtained means comparison. Results Principal component analysis revealed five dimensions for pre-post comparison: Knowledge Acquisition, Perceptions of Role Modelling, Internal Beliefs and Reflections, Personality Variables and Institutional Influences. Non-parametric means comparison showed increased ratings for knowledge acquisition and institutional influences (p<0.001, whilst a decline was noted for the personality variables (p<0.05. Conclusion Cultural immersion has great potential to elicit positive shifts in attitudinal and knowledge related aspects of cultural awareness at early stages in medical curricula. Negative directions also suggest that students question their beliefs and behaviours relating to cultural knowledge.

  19. Methoxetamine, a novel psychoactive substance with serious adverse pharmacological effects: a review of case reports and preclinical findings.

    An increasing number of novel psychoactive substances are currently available and sold as 'legal highs' or 'research chemicals' accompanied by the indication that they are 'not for human consumption'. Among those that have emerged in the last few years, methoxetamine (MXE) owes its wide popularity to its easy access on the Internet and its reputation of being a 'safe' drug. MXE is an arylcyclohexylamine with a chemical structure analogous to ketamine and phencyclidine, and similar noncompetitive glutamate N-methyl D-aspartate receptor antagonist properties. Yet, very recent preclinical data highlighted a stimulatory effect of MXE on dopamine neurotransmission within the mesolimbic pathway. The aim of this review is to provide an updated review of the behavioral and toxicological effects of MXE as well as the latest findings on its pharmacology that might explain sought effects and frequent occurrence of adverse effects. In light of the growing number of intoxications induced by MXE, knowledge of its short-term and long-term effects is urgently needed. However, the hypothetical rapid antidepressant activity of MXE suggested by its chemical analogy with ketamine and supported by recent preclinical findings deserves further investigation.

    Full Text Available Objectives. To estimate the age- and gender-specific consultation rates of patients who availed primary health care service in Greenland and to analyse contact patterns among patients in Nuuk. Design. Observational and cross-sectional register study using data captured from the medical records. Materials and methods. The number of patients specified by age and gender who had contacted the primary health care centres within the last year was identified using a statistic module applied to the electronic medical records system. The population as it was on the 1st of January 2011 was used as the background population. The age- and gender-specific consultation rates were calculated. Review of most recent contact was performed in a subsample of patients from Nuuk, and information of the type of contact and diagnoses was obtained. Results. Eighty-three percent of the population in Greenland had been in contact with the primary health care centre within the last year. Females were more frequent users than males. A subsample of 400 patients in Nuuk was identified. Personal contact was the most frequent type of consultation (75.8%, followed by telephone (14.8% and e-mail (9.8% consultations. Musculoskeletal symptoms accounted for the most frequent bases for diagnoses. Conclusion. More than 80% of the whole population has been in contact with the primary health care system within the last year. This indicates that opportunistic case-finding of chronic diseases such as diabetes, hypertension, etc. providing a possible strategy for decreasing the number of undiagnosed cases.

  1. Accuracy of Cytology for Diagnosis of Lipomatous Tumors: Comparison with Magnetic Resonance and Computed Tomography Findings in 175 cases

    Einarsdottir, H.; Skoog, L.; Soederlund, V.; Bauer, H.C.F. [Karolinska Univ. Hospital, Stockholm (Sweden). Dept. of Radiology

    2004-12-01

    Purpose: To assess the value of fine-needle aspiration cytology in the diagnostic work-up of lipomatous tumors of the extremities and trunk, and to identify specific radiological features that could aid in the preoperative evaluation. Material and Methods: 175 patients with subfascial lipomatous tumors who had undergone preoperative magnetic resonance imaging or computed tomography and fine-needle aspiration cytology were studied. The percentage of fat within the lesion was visually graded from the images as: none, 1-75%, 75-95%, or 95-100%. The histological and cytological diagnoses were compared and in discordant cases the radiological images were re-reviewed. Results: There was cytological and histological concordance in 96% of lipomas and in 85% of atypical lipomatous tumors (ALT) and liposarcomas. Most discordant cases exhibited 1-75% fat. Radiological review suggested that cytological sampling problems due to tumor heterogeneity were the main cause of diagnostic difficulties. The majority of tumors with less than 75% fat were liposarcomas, and in no liposarcoma was the fat content higher than 75%. Both ALT and lipoma were found in the 95-100% group. Conclusion: Cytology can be highly accurate in the diagnosis of lipomatous tumors, including ALT; however, critical comparison with the radiological findings increases diagnostic security. In tumors with fat content visually assessed as less than 75% of the tumor volume, liposarcoma is the most likely diagnosis and a cytological diagnosis of ALT or lipoma should be questioned. In lesions with 75-95% fat, liposarcoma is unlikely, but FNAC is still indicated for safety. In lesions with 95-100% fat, FNAC is only indicated if the differentiation between lipoma and ALT influences the treatment strategy.

    Hansen's disease, or leprosy, is a chronic infectious disease with many manifestations. Though still a major health concern and leading cause of peripheral neuropathy in the developing world, it is rare in the United States, with only about 150 cases reported each year. Nevertheless, it is imperative that neurosurgeons consider it in the differential diagnosis of neuropathy. The causative organism is Mycobacterium leprae, which infects and damages Schwann cells in the peripheral nervous system, leading first to sensory and then to motor deficits. A rare presentation of Hansen's disease is pure neuritic leprosy. It is characterized by nerve involvement without the characteristic cutaneous stigmata. The authors of this report describe a case of pure neuritic leprosy presenting as ulnar nerve neuropathy with corresponding radiographic, electrodiagnostic, and histopathological data. This 11-year-old, otherwise healthy male presented with progressive right-hand weakness and numbness with no cutaneous abnormalities. Physical examination and electrodiagnostic testing revealed findings consistent with a severe ulnar neuropathy at the elbow. Magnetic resonance imaging revealed diffuse thickening and enhancement of the ulnar nerve and narrowing at the cubital tunnel. The patient underwent ulnar nerve decompression with biopsy. Pathology revealed acid-fast organisms within the nerve, which was pathognomonic for Hansen's disease. He was started on antibiotic therapy, and on follow-up he had improved strength and sensation in the ulnar nerve distribution. Pure neuritic leprosy, though rare in the United States, should be considered in the differential diagnosis of those presenting with peripheral neuropathy and a history of travel to leprosy-endemic areas. The long incubation period of M. leprae, the ability of leprosy to mimic other conditions, and the low sensitivity of serological tests make clinical, electrodiagnostic, and radiographic evaluation necessary for diagnosis

    This project sought to describe the involvement of doctors in leadership roles in the NHS and the organisational structures and management processes in use in NHS trusts. A mixed methods approach was adopted combining a questionnaire survey of English NHS trusts and in-depth case studies of nine organisations who responded to the survey. Respondents identified a number of challenges in the development of medical leadership, and there was often perceived to be an engagement gap between medical leaders and doctors in clinical roles. While some progress has been made in the development of medical leadership in the NHS in England, much remains to be done to complete the journey that started with the Griffiths Report in 1983. We conclude that a greater degree of professionalism needs to be brought to bear in the development of medical leadership. This includes developing career structures to make it easier for doctors to take on leadership roles; providing training, development and support in management and leadership at different stages of doctors' careers; and ensuring that pay and other rewards are commensurate with the responsibilities of medical leaders. The time commitment of medical leaders and the proportion of doctors in leadership roles both need to increase. The paper concludes considering the implications of these findings for other health systems.

    Full Text Available Introduction & Background: Benign lesions are very common in breast. The most important consideration for physicians is to differentiate benign processes from malignant ones .Hence the clinicians and radi-ologists both wish to differentiate them even before surgical procedures. The Iranian Center for Breast Cancer linked to Jahad Daneshgahi Center is a referral place for patients with breast complaints. Patients & Methods: Retrospective study of sonographic findings of 111 patients with benign patho-logic diagnosis revealed 72.1% accuracy for sonogra-phy in diagnosing benign masses. In 31 cases (27.9%, the sonographic diagnosis was incorrect. Among the different benign lesions, the most common lesions were cysts, fibradenomas, and fibrocystic changes with respective sonographic accuracy of 100%, 90%, and 62.5%. Results: It shows that sonography has a high sensitiv-ity for diagnosis of benign breast lesions and this sen-sitivity is higher in cysts and fibradenomas which are the most common benign pathologies of breast. Conclusion: As a result, in this center sonography is an imaging modality for evaluating benign breast le-sion especially in young patients with dense breasts and palpable masses. Its unique role in diagnosis of the cysts is valuable especially to avoid repeated biopsies.

    Neuroleptic malignant syndrome (NMS) is a rare but potentially fatal disorder. In forensic cases, post-mortem diagnosis of NMS is sometimes difficult if ante-mortem information, such as neuroleptic ingestion or signs and symptoms, cannot be obtained. A 39-year-old Japanese male on a neuroleptic treatment regimen suddenly became agitated and died. Autopsy revealed muscle rigidity and hyperthermia. Post-mortem examination of blood revealed elevation of creatine phosphokinase-MM (CK-MM) and lactate dehydrogenase-4 and dehydrogenase-5 (LDH-4 and LDH-5). In renal glomeruli and tubules, myoglobin was stained immunohistochemically. From these findings, the cause of death was considered to be NMS. To support the diagnosis of NMS, both skeletal and cardiac muscles were stained with actin, myoglobin, desmin and mitochondria antibodies immunohistochemically. Actin, myoglobin, desmin, and mitochondria had been lost from skeletal, but not from the cardiac muscle, which suggested that only the skeletal muscle was damaged. Moreover, because mitochondria had disappeared only from the skeletal muscle, it was considered that skeletal muscle degeneration was caused by mitochondrial damage. Therefore, it is suggested that immunostaining of skeletal muscle by antibodies for muscle-associated proteins and mitochondria is useful to corroborate a diagnosis of NMS.

    We evaluated a simple computational model of productive vocabulary acquisition, applied to simulating two case studies of 7-year-old children with developmental word-finding difficulties across four core behavioural tasks. Developmental models were created, which captured the deficits of each child. In order to predict the effects of intervention, we exposed the computational models to simulated behavioural interventions of two types, targeting the improvement of either phonological or semantic knowledge. The model was then evaluated by testing the predictions from the simulations against the actual results from an intervention study carried out with the two children. For one child it was predicted that the phonological intervention would be effective, and the semantic intervention would not. This was borne out in the behavioural study. For the second child, the predictions were less clear and depended on the nature of simulated damage to the model. The behavioural study found an effect of semantic but not phonological intervention. Through an explicit computational simulation, we therefore employed intervention data to evaluate our theoretical understanding of the processes underlying acquisition of lexical items for production and how they may vary in children with developmental language difficulties.

    Full Text Available Acetylcholinesterase (AChE inhibition enhances learning and cognitive ability for treatment of Alzheimer's disease. Polysaccharide–peptide complexes were identified in Cordyceps militaris (CPSPs and characterized for their AChE inhibitory properties. Three polymers (CPSP-F1, -F2, and -F3 were extracted and separated by ultrasound-assisted extraction and diethylaminoethanol (DEAE–Sepharose CL-6B column chromatography. Polysaccharide–peptide complexes were identified by DEAE–Sepharose CL-6B column chromatography and high-performance gel-filtration chromatography, Fourier transform infrared spectra, amino sugar composition analysis, and β-elimination reaction to identify polysaccharide–peptide bond categories. Separation of CPSP can increase AChE inhibitory activity from the crude polysaccharide of C. militaris. CPSP-F1 and CPSP-F2 exhibited half maximal inhibitory concentrations of 32.2 ± 0.2 mg/mL and 5.3 ± 0.0 mg/mL. Thus, we identified polysaccharide–peptide complexes from C. militaris and suggest CPSP has great potential in AChE inhibition bioassay.

  11. MR findings of ovarian tumors with hormonal activity, with emphasis on tumors other than sex cord-stromal tumors

    International Nuclear Information System (INIS)

    Sex cord-stromal tumors including granulosa cell tumor, thecoma, Sertoli stromal cell tumor and steroid cell tumor are noted for their hormonal activity. However, there are many kinds of ovarian tumors other than sex cord-stromal tumors and tumor-like conditions with endocrine manifestations. Cross-sectional imaging, especially MR, can provide precise features of ovarian tumors and uterine morphological change even in a clinically latent excess of estrogen. In this article, we demonstrate typical imaging findings of ovarian tumors with hormonal activity. We also shortly explain the mechanism of the virilization and hyperestrogenism caused by ovarian tumors and tumor-like conditions

    Full Text Available Abstract Background Health care providers in many countries have delivered interventions to improve physical activity levels among their patients. Thus far, less is known about the population's interest to increase their physical activity levels and their opinion about the health care provider's role in physical activity promotion. The aims of this paper were to investigate the self-reported physical activity levels of the population and intention to increase physical activity levels, self-perceived need for support, and opinions about the responsibilities of both individuals and health care providers to promote physical activity. Methods A regional public health survey was mailed to 13 440 adults (aged 18-84 years living in Östergötland County (Sweden in 2006. The survey was part of the regular effort by the regional Health Authorities. Results About 25% of the population was categorised as physically active, 38% as moderately active, 27% as somewhat active, and 11% as low active. More than one-third (37% had no intentions to increase their physical activity levels, 36% had thought about change, while 27% were determined to change. Lower intention to change was mainly associated with increased age and lower education levels. 28% answered that physical activity was the most important health-related behaviour to change "right now" and 15% of those answered that they wanted or needed support to make this change. Of respondents who might be assumed to be in greatest need of increased activity (i.e. respondents reporting poor general health, BMI>30, and inactivity more than one-quarter wanted support to make improvements to their health. About half of the respondents who wanted support to increase their physical activity levels listed health care providers as a primary source for support. Conclusions These findings suggest that there is considerable need for physical activity interventions in this population. Adults feel great responsibility for

    Full Text Available Introduction: Visceral artery aneurysms are rare vas-cular diseases whose pathogenesis and natural history remain incompletely understood. Herein we describe an 80 year-old man with concomitant superior mes-enteric, celiac, renal, and aorto-iliac aneurysms. To the best of our knowledge this constellation of arte-rial aneurysms has not been described yet."nCase Presentation: An 80-year-old man was referred to our institution due to presence of tarry stool and one episode of vomiting of coffee ground material. The patient underwent an upper GI endoscopy which revealed esophageal varicosities. Due to presence of esophageal varicosities and clinical suspicion of portal vein thrombosis an ultrasonographic Doppler study of portal venous system was performed in this patient which revealed normal diameter and flow in portal and splenic veins with no evidence of thrombosis; however incidentally aneurismal dilatation of celiac and superior mesenteric arteries and lower part of abdominal aorta and both iliac arteries were found during the ultrasonographic examination. Abdominal CT scan was performed in this patient, which re-vealed aneurismal dilatation of main celiac artery and its main branches. There was also aneurismal dilata-tion of superior mesenteric artery. Aneurismal dilata-tion of distal abdominal aorta with extension to both side common, external, and internal iliac arteries was also seen. MRA of abdomen was also performed which revealed the previous findings plus apparent dilatation of proximal part of right main renal artery which was not considered in previous abdominal CT scan. Since then; he has remained asymptomatic and stable, with no evidence of further expansion of his aneurysms in routine sonographic examinations."nDiscussion: Our patient was a hypertensive hyperlip-idemic old man with history of previous TIA and atherosclerotic carotid plaques, so the most important predisposing factor seemed to be atherosclerosis.

    The concept of joint implementation as a way to implement climate change mitigation projects in another country has been controversial ever since its inception. Developing countries have raised numerous issues at the project-specific technical level, and broader concerns having to do with equity and burden sharing. This paper summarizes the findings of studies for Brazil, India, Mexico and South Africa, four countries that have large greenhouse gas emissions and are heavily engaged in the debate on climate change projects under the Kyoto Protocol. The studies examine potential or current projects/programs to determine whether eight technical concerns about joint implementation can be adequately addressed. They conclude that about half the concerns were minor or well managed by project developers, but concerns about additionality of funds, host country institutions and guarantees of performance (including the issues of baselines and possible leakage) need much more effort to be adequately addressed. All the papers agree on the need to develop institutional arrangements for approving and monitoring such projects in each of the countries represented. The case studies illustrate that these projects have the potential to bring new technology, investment, employment and ancillary socioeconomic and environmental benefits to developing countries. These benefits are consistent with the goal of sustainable development in the four study countries. At a policy level, the studies' authors note that in their view, the Annex I countries should consider limits on the use of jointly implemented projects as a way to get credits against their own emissions at home, and stress the importance of industrialized countries developing new technologies that will benefit all countries. The authors also observe that if all countries accepted caps on their emissions (with a longer time period allowed for developing countries to do so) project-based GHG mitigation would be significantly

    The Internet increasingly enables diverse health communication activities, from information seeking to social media interaction. Up-to-date reporting is needed to document the national prevalence, trends, and user profiles of online health activities so that these technologies can be best used in health communication efforts. This study identifies prevalence, trend, and factors associated with seeking health information, e-mailing health care providers, and using social media for health purposes. Four iterations of HINTS survey data, collected in 2003, 2005, 2008, and 2012, were analyzed to assess population-level trends over the last decade, and current prevalence of Internet-based health communication activities. Sociodemographic and health correlates were explored through weighted logistic regression modeling. Findings demonstrated that Internet use has steadily increased, with 78% of U.S. adults online in 2012; however several digital divide factors--among them education, age, and race/ethnicity--still predict access. Once online, 70% of adults use the Internet as their first source for health information, and while 19% have e-mailed health care providers, engagement in health communication on social media is still relatively low. Distinct user profiles characterize each type of communication, with age, population density, and gender emerging as important predictors across online health activities. These findings have important implications for health communication research and practice. PMID:26042588

    Full Text Available Intravascular large B-cell lymphoma is a rare and aggressive variant of diffuse large B-cell non-Hodgkin′s lymphoma. Its atypical presentation often delays the diagnosis and due to its aggressive behavior, the diagnosis is made post-mortem in half of the cases. We present FDG PET/CT findings in a case of IVLCL. In our case, the report of the patient′s bone marrow biopsy after death of the patient revealed the presence of IVLCL. After availability of final diagnosis, we reviewed the literature and a better explanation of the FDG PET/CT findings could be obtained. We describe this case, to call for heightened awareness in physicians for the rare but possible diagnosis of IVCLL, particularly in an elderly patient who presents with fever of unknown origin and demonstrates similar FDG PET/CT findings. Considering the characteristic scan findings described in our patient and other cases in literature, FDG PET/CT can be used in suspected cases of IVLCL for early diagnosis of this rapidly fatal malignancy.

    Previous studies demonstrated that antibodies against triosephosphate isomerase of Taenia solium (TTPI) can alter its enzymatic catalysis. In the present study, we used antibodies produced against the NH2-terminal region of TTPI (1/3NH2TTPI) and the phage display technology to find target regions to inhibit TTPI activity. As a first step, we obtained polyclonal antibodies against non-conserved regions from the 1/3NH2TTPI, which had an inhibitory effect of about 74 % on catalytic activity. Afterward, they were used to screen a library of phage-displayed dodecapeptides; as a result, 41 phage mimotope clones were isolated and grouped according to their amino acid sequence, finding the consensus A1 (VPTXPI), A2 (VPTXXI), B (LTPGQ), and D (DPLPR). Antibodies against selected phage mimotope clones were obtained by rabbit's immunization; these ones clearly recognized TTPI by both Western blot and ELISA. However, only the mimotope PDTS16 (DSVTPTSVMAVA) clone, which belongs to the VPTXXI consensus, raised antibodies capable of inhibiting the TTPI catalytic activity in 45 %. Anti-PDTS16 antibodies were confronted to several synthetic peptides that encompass the 1/3NH2TTPI, and they only recognized three, which share the motif FDTLQK belonging to the helix-α1 in TTPI. This suggests that this motif is the main part of the epitope recognized by anti-PDTS16 antibodies and revealed its importance for TTPI catalysis.

    NCE Smart Energy Markets conducted in the period 2009 - 2010 a foresight process in which it was conducted a preliminary meeting, a kick-off meeting, four major collections and a 'recovery meeting' way for players who would enter the process. As a result, they decided to continue a joint process management meetings under the name of the cluster with new collections 2010 - 2011 with the same external process manager. VRI Oestfold; Oestfold Research helped with follow-up evaluation of the process and presented in this report findings from the evaluation of the process. The purpose of the evaluation was, among other things, to contribute to a good process flow, documentation of experiences and achievements and contributions to better understanding and discussion about the direction and emphasis on the way. The evaluation aimed to answer the following three questions: Are the expected results achieved? Is the process complete successfully?Is foresight appropriate instrument in the given situation?The findings indicate that participants perceive that they are on course to reach the goals that are related to the community; common cluster strategy for growth and renewal, carving out the correct goals for the future, the process for getting into a committed relationship, and develop an innovative environment that can stay ahead of the market. At the same time they perceive that they are not close to having achieved the one goal that is directly related to the individual company - to contribute to the individual company's strategy will be more successful. Process management is perceived as a distinct and developing well underway, while project management is perceived as not quite so obvious, but in a better development. When we look at the core businesses consisting of few active businesses and some of the original have reduced their participation, while a number new have come to the last two workshops. It also appears that there is a potential to increase
