    Full Text Available Background At present of the limitation of the current case finding strategies and the global urgency to improve tuberculosis (TB case finding, a renewed interest in active case finding (ACF has risen. World Health Organization (WHO calls for research on TB screening among low-income countries because of the limitation of the passive case finding strategies. We aimed to evaluated Active Case Finding strategy for TB among the slums population in North of Iran (Gorgan city and comprise this procedure to Passive Case Finding. Materials and Methods We conducted a house-to-house survey from April 2016 to July 2016 by trained health volunteers for TB in ten urban slums of Gorgan. Individuals with TB symptoms were identified through targeted screening using a standardized questionnaire and investigated further for TB. Descriptive analyses were performed using Stata-12. Results During study period, of 22,741 individuals screened for TB, 112 (0.49% were identified as TB suspects; 95 suspects were evaluated for TB. TB was diagnosed in four individuals, representing 4.2% of those evaluated for TB as suspected cases. The incidence rate of tuberculosis was 17.5 in 100.000 people in slums population of Gorgan. Of the four detected cases, three individuals had pulmonary TB that among them two cases had new smear-positive TB. Conclusion ACF could supplement current strategies to yield additional TB cases, lead to early diagnosis and better treatment.

    Nomadic populations are often isolated and have difficulty accessing health care, leading to increased morbidity and mortality. Although Nigeria has one of the highest tuberculosis (TB) burdens in Africa, case detection rates remain relatively low. Active case finding for TB among nomadic populations was implemented over a 2-year period in Adamawa State. A total of 378 community screening days were organised with local leaders; community volunteers provided treatment support. Xpert(®) MTB/RIF was available for nomads with negative smear results. Through active case finding, 96 376 nomads were verbally screened, yielding 1310 bacteriologically positive patients. The number of patients submitting sputum for smear microscopy statewide increased by 112% compared with the 2 years before the intervention. New smear-positive notifications increased by 49.5%, while notifications of all forms of TB increased by 24.5% compared with expected notifications based on historical trends. Nomads accounted for respectively 31.4% and 26.0% of all smear-positive and all forms TB notifications. Pre-treatment loss to follow-up and treatment outcomes were similar among nomads and non-nomads. Nomads in Nigeria have high TB rates, and active case-finding approaches may be useful in identifying and successfully treating them. Large-scale interventions in vulnerable populations can improve TB case detection.

    Document and analyze Ecuador's experience using active community case-finding for uptake of pregnant and postpartum women in Ecuador. A cross-sectional descriptive study was conducted of information obtained on active community case-finding of pregnant and postpartum women in the catchment areas of 200 primary care facilities of Ecuador's Ministry of Public Health. Visits were made to 460 451 homes in 20 provinces; 15 622 pregnant women and 4 014 postpartum women were identified. Of the pregnant women, 89% (13 875) had had at least one prenatal check-up, while 70% of postpartum women (4 014) had had at least one post-delivery or post-caesarean check-up. Potential risk was identified in 29% of pregnant women (4 601). Orellana and Sucumbíos provinces had the lowest percentages of pregnant women with at least one prenatal check-up and the lowest percentages of postpartum women with at least one postpartum checkup. A total of 3 951 brigades were formed at the national level for this activity. Active community case-finding was valuable in identifying pregnant and postpartum women who had not been captured by the health system, especially to detect their risk status, in addition to the advantages of participatory uptake, especially with support from universities with health majors. Low coverage for postpartum check-ups underscores the importance of learning why women do not receive this care. Similar experiences need to be systematized to improve the process.

    In India, to increase tuberculosis (TB) case detection under the National Tuberculosis Programme, active case finding (ACF) was implemented by the Global Fund-supported Project Axshya, among high-risk groups in 300 districts. Between April 2013 and December 2014, 4.9 million households covering ~20 million people were visited. Of 350 047 presumptive pulmonary TB cases (cough of ⩾2 weeks) identified, 187 586 (54%) underwent sputum smear examination and 14 447 (8%) were found to be smear-positive. ACF resulted in the detection of a large number of persons with presumptive pulmonary TB and smear-positive TB. Ensuring sputum examination of all those with presumptive TB was a major challenge.

    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.

    The early detection and diagnosis of chronic obstructive pulmonary disease (COPD) is critical to providing appropriate and timely treatment. We explored a new active case-finding strategy for COPD using handheld spirometry.We recruited subjects over 40 years of age with a smoking history of more than 10 pack-years who visited a primary clinic complaining of respiratory symptoms. A total of 190 of subjects were enrolled. Medical information was obtained from historical records and physical examination by general practitioners. All subjects had their pulmonary function evaluated using handheld spirometry with a COPD-6 device. Because forced expiratory volume in 6 seconds (FEV6) has been suggested as an alternative to FVC, we measured forced expiratory volume in 1 second (FEV1)/FEV6 for diagnosis of airflow limitation. All subjects were then referred to tertiary referral hospitals to complete a "Could it be COPD?" questionnaire, handheld spiromtery, and conventional spirometry. The results of each instrument were compared to evaluate the efficacy of both handheld spirometry and the questionnaire.COPD was newly diagnosed in 45 (23.7%) patients. According to our receiver-operating characteristic (ROC) curve analysis, sensitivity and specificity were maximal when the FEV1/FEV6 ratio was less than 77%. The area under the ROC curve was 0.759. The sensitivity, specificity, positive predictive value, and negative predictive value were 72.7%, 77.1%, 50%, and 90%, respectively. The area under the ROC curve of respiratory symptoms listed on the questionnaire ranged from 0.5 to 0.65, which indicates that there is almost no difference compared with the results of handheld spirometry.The present study demonstrated the efficacy of handheld spirometry as an active case-finding tool for COPD in a primary clinical setting. This study suggested that physicians should recommend handheld spirometry for people over the age of 40, who have a smoking history of more than 10 pack

    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

    Full Text Available Background: The World Health Organization strongly recommends regular screening for tuberculosis (TB in HIV-positive individuals. Objective: To compare the outcome of anti-tuberculosis treatment (ATT in HIV-positive adults diagnosed with TB through active case-finding (ACF or passive case-finding (PCF. Design: Antiretroviral therapy (ART-naïve adults diagnosed with TB were included from two prospective cohort studies conducted in Ethiopia between September 2010 and March 2013. The PCF cohort was based at out-patient TB clinics, whereas participants in the ACF cohort were actively screened for TB by bacteriological sputum testing (smear microscopy, Xpert MTB/RIF assay, and liquid culture without pre-selection on the basis of symptoms and signs. Outcomes of ATT were compared between participants in the two cohorts; characteristics at diagnosis and predictors of adverse outcomes were analysed. Results: Among 439 TB/HIV co-infected participants, 307 and 132 belonged to PCF and ACF cohorts, respectively. Compared with the ACF participants, hemoptysis, conjunctival pallor, bedridden status, and low mid upper-arm circumference (MUAC were significantly more common in participants identified through PCF. Sputum smear-positivity rates among pulmonary TB cases were 44.2% and 21.1% in the PCF and ACF cohorts, respectively (p<0.001. Treatment success was ascertained in 247 (80.5% of the participants in the PCF cohort and 102 (77.2% of the participants in the ACF cohorts (p=0.223. Low MUAC (p=0.001 independently predicted mortality in the participants in both cohorts. Conclusion: Although patients identified through ACF had less advanced TB disease, ATT outcome was similar to the patients identified through PCF. To achieve a better outcome, case management in ACF strategy should be strengthened through enhanced patient-centred counselling and adherence support.

    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

    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.

    Full Text Available Background. One of the main strategies for the early detection of pulmonary tuberculosis (PTB is through the screening of individuals with symptoms compatible with PTB. Although this is programmatic strategy for active case finding, its yield is not well known. Objective. To determine the yield of pulmonary tuberculosis active case finding through the screening of respiratory symptomatic (RS patients at a general hospital. Methods. RS patients were defined as subjects complaining of cough and/or sputum for a period of 2 or more weeks. Outpatients and their companions were approached while they waited in the outpatient care areas of the hospital to detect RS. Two samples from different days or 2 samples taken 2 hours apart on the same day were collected. Results. 122 RS patients were identified. Fifty-seven patients (46.7% had at least one sputum sample analyzed. Three patients presented a positive smear and 2 were culture positive; neither had upper airway symptoms. None of the patients with productive cough and upper airway symptoms had a positive smear (. Only 19 (33.3% returned to the laboratory to retrieve their results. Conclusion. Current strategy to screen RS patients based only on clinical data has a low compliance. Specific strategies to increase compliance (removal of barriers, incentives, etc. should be implemented.

    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 While community-based active case finding (ACF for tuberculosis (TB holds promise for increasing early case detection among hard-to-reach populations, limited data exist on the acceptability of active screening. We aimed to identify barriers and explore facilitators on the pathway from diagnosis to care among TB patients and health providers.Mixed-methods study. We administered a survey questionnaire to, and performed in-depth interviews with, TB patients identified through ACF from poor urban settlements in Phnom Penh, Cambodia. Additionally, we conducted focus group discussions and in-depth interviews with community and public health providers involved in ACF, respectively.Acceptance of home TB screening was strong among key stakeholders due to perceived reductions in access barriers and in direct and indirect patient costs. Privacy and stigma were not an issue. To build trust and facilitate communication, the participation of community representatives alongside health workers was preferred. Most health providers saw ACF as complementary to existing TB services; however, additional workload as a result of ACF was perceived as straining operating capacity at public sector sites. Proximity to a health facility and disease severity were the strongest determinants of prompt care-seeking. The main reasons reported for delays in treatment-seeking were non-acceptance of diagnosis, high indirect costs related to lost income/productivity and transportation expenses, and anticipated side-effects from TB drugs.TB patients and health providers considered home-based ACF complementary to facility-based TB screening. Strong engagement with community representatives was believed critical in gaining access to high risk communities. The main barriers to prompt treatment uptake in ACF were refusal of diagnosis, high indirect costs, and anticipated treatment side-effects. A patient-centred approach and community involvement were essential in mitigating barriers

    Background Globally, case detection of tuberculosis (TB) has stabilized in recent years. Active case finding (ACF) has regained an increased attention as a complementary strategy to fill the case detection gap. In the Philippines, the DetecTB project implemented an innovative ACF strategy that offered a one-stop diagnostic service with a mobile unit equipped with enhanced diagnostic tools including chest X-ray (CXR) and Xpert®MTB/RIF (Xpert). The project targeted the rural poor, the urban poor, prison inmates, indigenous population and high school students. Methods This is a retrospective review of TB screening data from 25,103 individuals. A descriptive analysis was carried out to compare screening and treatment outcomes across target populations. Univariate and multivariate analyses were performed to identify predictors of TB for each population. The composition of bacteriologically-confirmed cases by smear and symptom status was further investigated. Results The highest yield with lowest number needed to screen (NNS) was found in prison (6.2%, NNS: 16), followed by indigenous population (2.9%, NNS: 34), the rural poor (2.2%, NNS: 45), the urban poor (2.1%, NNS: 48), and high school (0.2%, NNS: 495). The treatment success rate for all populations was high with 89.5% in rifampicin-susceptible patients and 83.3% in rifampicin-resistant patients. A relatively higher loss to follow-up rate was observed in indigenous population (7.5%) and the rural poor (6.4%). Only cough more than two weeks showed a significant association with TB diagnosis in all target populations (Adjusted Odds Ratio ranging from 1.71 to 6.73) while other symptoms and demographic factors varied in their strength of association. The urban poor had the highest proportion of smear-positive patients with cough more than two weeks (72.0%). The proportion of smear-negative (Xpert-positive) patients without cough more than two weeks was the highest in indigenous population (39.3%), followed by prison

    Full Text Available Lipomas are common soft tissue tumors of mesenchymal origin.They contain mature adipose tissue. They are usually located in the subcutaneous tissue. They rarely ocur within the muscle and then are called intramuscular lipomas. Ultrasonography is the first diagnostic method to be selected. However, cross-sectional imaging methods are more useful in the diagnosis. On Magnetic resonance imaging (MRI, with the help of signal characteristics and fat suppression techniques,diagnosis is easily achieved. In addition, the relationship of lesion with the adjacent anatomical structures can be assessed better with MRI. Here, will be explained two different intramuscular lipoma cases and imaging findings will be reviewed. [J Contemp Med 2016; 6(3.000: 221-225

    Active tuberculosis (TB) screening outside clinics and in communities may reduce undiagnosed TB. To determine the yield of TB screening during community-based HIV testing campaigns (CHC) in 7 rural Ugandan communities within an ongoing cluster-randomized trial of universal HIV testing and treatment (SEARCH, NCT:01864603), we offered sputum microscopy to participants with prolonged cough (>2 weeks). We determined the number of persons needed to screen to identify one TB case, and the number of cases identified that linked to clinic and completed TB treatment. Of 36,785 adults enumerated in 7 communities, 27,214 (74%) attended CHCs, and HIV testing uptake was >99%, with 941 (3.5%) HIV-infected adults identified. Five thousand seven hundred eighty-six adults (21%) reported cough and 2876 (11%) reported cough >2 weeks. Staff obtained sputum in 1099/2876 (38%) participants with prolonged cough and identified 10 adults with AFB-positive sputum; 9 new diagnoses and 1 known case already under treatment. The number needed to screen to identify one new TB case was 3024 adults overall: 320 adults with prolonged cough and 80 HIV-infected adults with prolonged cough. All 9 newly diagnosed AFB+ participants were linked to TB care within 2 weeks and were initiated TB treatment. In a rural Ugandan setting, TB screening as an adjunct to large-scale mobile HIV testing campaigns provides an opportunity to increase TB case detection.

    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 Much recent research and funding have focused on building Internet-based repositories that contain collections of high-quality learning resources, often called ‘learning objects.’ Yet little is known about how non-specialist users, in particular teachers, find, access, and use digital learning resources. To address this gap, this article describes a case study of mathematics and science teachers’ practices and desires surrounding the discovery, selection, and use of digital library resources for instructional purposes. Findings suggest that the teacher participants used a broad range of search strategies in order to find resources that they deemed were age-appropriate, current, and accurate. They intended to include these resources with little modifications into planned instructional activities. The article concludes with a discussion of the implications of the findings for improving the design of educational digital library systems, including tools supporting resource reuse.

    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. PMID:22937328

    2016-01-01

    Full Text Available Current World Health Organisation targets calling for an end to the global tuberculosis (TB epidemic by 2035 require a dramatic improvement in current case-detection strategies. A reliance on passive case finding (PCF has resulted consistently, in over three million infectious TB cases per year, being missed by the health system, leading to ongoing transmission of infection within families and communities. Active case finding (ACF for TB has been recognized as an important complementary strategy to PCF, in order to diagnose and treat patients earlier, reducing the period of infectiousness and therefore transmission. ACF may also achieve substantial population-level TB control. Local TB epidemiology and the resources available in each setting will influence which populations should be screened, and the types of ACF interventions to use for maximal impact. TB control programs should begin with the highest risk groups and broaden their activities as resources allow. Mathematical models can help to predict the population-level effects and the cost-effectiveness of a variety of ACF strategies on different risk populations.

    We reported two cases of clinically typical melasma presenting with unusual histopathologic findings. In one case, the epidermal melanocytes were markedly increased in number and protruded into the dermis, and in the other case, increased epidermal pigmentation as well as dermal melanocytosis were found. We suggested that the various treatment modalities of melasma should be applied depend on its histopathologic finding. PMID:16614533

  18. Finding Community Structures In Social Activity Data

    KAUST Repository

    Peng, Chengbin

    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

    2016-10-03

    Given that surveys, as well as frequent observations by institute faculty, indicate that many candidates have difficulty finding control cases and maintaining immersion and that many graduate analysts face similar challenges, it would seem that psychoanalytic training does not prepare candidates adequately for finding patients and practicing analysis while in training and, for many, after they have graduated. Although external challenges are formidable, it is by identifying and making use of internal challenges to finding cases that candidates can develop an analytic mind: the identity, approach, and skills necessary not only to graduate but to have the choice to practice clinical psychoanalysis post-graduation. Some of the internal challenges and their manifestations in different phases of initiating analysis (referrals, initial consultation, recommendation) are discussed and two detailed examples are offered to illustrate the productive use of candidates' countertransferences in finding cases and maintaining immersion. Finally, recommendations for institutional solutions are provided. © 2016 by the American Psychoanalytic Association.

    Three cases with hypersensitivity pneumonitis were studied with Tl-201 scintigraphy, perfusion lung scan and other clinical findings. Major symptoms and signs were fever and cough in 3 cases, exertional dyspnea in 2, sputum in 1 and moist rales in 3. Laboratory data showed elevated ESR, hyper ..gamma..-globulinemia in 3 cases, leukocytosis in 2, eosinophilia in 3, positive CRP in 2 and positive RA test in 1. Chest x-ray film revealed diffuse scattered reticulonodular shadows in 3 cases and patchy ones in 2. Abnormalities in the pulmonary function tests were decreased vital capacity and Pa sub(o2) in 3 cases, increased residual volume and decreased diffusion capacity in 2, decreased V50 and V25 in flow volume curve in 1. Precipitating antibodies against Sitophilus granarius, Thermoactinomyces vulgaris, Micropolyspola faeni, Aspergillus fumigatus and budgerigar serum were detected. Tl-201 scintigram showed diffuse marked uptake of Tl-201 in both lungs of 2 cases at acute stage and moderate in 2 cases in remission when abnormal shadows on chest x-ray film had been disappeared. Two cases in remission showed slight positive or negative results, but in 1 case moderate uptake was yet observed after 11 months. Positive visualization of right ventricle was demonstrated in 2 cases. Perfusion lung scintigram showed decreased perfusion in 3 cases. Each of 2 cases in acute stage and in remission showed slightly decreased perfusion and one case in admission showed a moderate decrease and still showed a slight decrease after 9 months.

    Revesz syndrome is a variant of dyskeratosis congenita characterized by aplastic anemia, retinopathy, and central nervous system abnormalities. We describe a 3-year-old boy in whom the spectrum of neuroimaging findings, including intracranial calcifications, cerebellar hypoplasia and unusual brain lesions were found by biopsy to be gliosis despite their enhancement and progression. In patients with dyskeratosis-related syndromes, non-neoplastic parenchymal brain lesions occur and gliosis should be considered in the differential diagnosis for progressive enhancing brain lesions. Should this finding be confirmed consistently in additional cases, brain biopsy could potentially be avoided. (orig.)

    Medulloblastoma is a brain tumor of neuro epithelial 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. (author)

    Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering peripheral, cranial and autonomic nerves. Twenty-five to forty-five percent of all schwannomas occur in the head and neck region, but location of such tumors in the larynx is rarely observed. The present report is aimed at describing a clinical case of laryngeal schwannoma, with emphasis on sonographic findings. (author)

    We present a case finding study of serologically confirmed Pertussis amongst BFG-based returnees from Op HERRICK. The role of Pertussis in the aetiology of the commonplace "Kabul Cough" is discussed. It is recommended that enhanced health surveillance for Pertussis takes place both during and after future deployments to Afghanistan, to prevent the potential onward transmission of a potentially fatal illness to unimmunised children.

    Grange syndrome comprises arterial stenoses with hypertension, brachysyndactyly, bone fragility, learning disability, and cardiac defects. To date, we know of two reported families with five affected individuals. We report on one of the youngest cases, in a third family, a 3-year-old girl with brachysyndactyly, renal artery stenosis with hypertension, and bone fragility. She does not have apparent cardiac disease, suggesting cardiac anomalies may not be an obligatory finding in this 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

    Kimura disease is a rare chronic inflammatory condition of unknown origin that occurs mainly in young Asian male patients. Kimura disease is characterized by painless subcutaneous swelling and lymphadenopathy of the head and neck, associated with peripheral blood eosinophilia and increased serum IgE. According to some previous reports about a rare form of Kimura disease of the upper arm, soft tissue masses of the subcutaneous fat layer were demonstrated in the medial trochlear area, which showed strong and homogenous enhancement with marked perilesional edema and fat infiltrations on enhanced magnetic resonance imaging (MRI). In this case report, we introduce a case of Kimura disease of the upper arm in a 13-year male patient, which was seen as a well-marginated soft tissue mass without perilesional edema or fatty infiltrations on MRI. In this case study, we discuss the characteristics of the clinical and pathologic findings associated with unusual MRI findings, and report the Kimura disease with a different pathophysiology by anti-inflammatory drugs.

    Full Text Available Recently, the veterinarians are dealing with a number of cases that require forensic expertise. Such a circumstance could be the accidental electrocution in animals, one of the causes of unnatural death. There is a scarcity with reference to the pathological findings in veterinary forensic medicine. In this paper, we present the main lesions that occurred in a horse with accidental electrocution that was presented for complete necropsy survey. A horse corpse was sent to the Pathology Department (Faculty of Veterinary Medicine, Cluj-Napoca, Romania for a full medical survey. Preliminary results and external examination: the body was in rigor mortis; from the nasal cavities drained out reddish foam and in the mouth was observed the presence of ingested feed (straw that was not chewed, suggesting a quick death. The findings detected after internal examination of the carcass were poor blood coagulability, haemorrhagic diathesis throughout the body, with haemorrhages of various sizes in different body regions (e.g., muscles of the withers, in the gluteal muscle, the mucosa of epiglottis, larynx, trachea, in the interstitium of the lung, and ecchymosis in the left kidney. Some other lesions detected were infarcts and haemorrhages in the fundic region of the stomach’s mucosa. In electrocution, haemorrhages are most often located in the respiratory tract, aspect observed in our case too. However, the diagnosis of electrocution has to corroborate the necropsy findings (which are not specific, with some other data such as the fulminant death and inspection of power source.

    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.

    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.

    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

    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.

    2009-10-15

    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.

    A case of acute ergotism with angiographic demonstration of bilateral femoral artery involvement is reported. A 27-year-old married woman was admitted because of sudden onset of severe pain in both flanks and lower legs, followed by numbness and coldness of the skin on both legs. The attack occurred after the administration of ergot tartrate as postpartum care. Femoral arteriography was performed on 10th day of illness with the Seldinger technic. The femoral arteries were generally smaller in caliber than normal. There was no definite evidence of occlusive disease. Findings were more or less symmetrical and extended to lower legs where only fine branches were visualized. The final diagnosis was diffuse vasospasm due to acute ergotism with secondary occlusion of the arteries of lower leg bilaterally.

    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

    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.

    1994-09-01

    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.

    Early diagnosis of breast vasculitis (BV) is difficult because this condition is rare and occasionally mimics breast cancer clinically or radiologically. It may present as systemic disease or as an isolated lesion in the breast, without systemic evidence. When vasculitis appears in the breast, it also might manifest as a tumor-like lesion, and in previous cases, tissue acquisition was needed for confirmation of the diagnosis because of BV's resemblance to inflammatory breast cancer. We report a case of isolated BV that was suspected of being inflammatory breast cancer clinically, but manifested as bilateral breast edema on mammography. In this case, sonographic findings included not only nonspecific edema findings that might be seen in other cases, but also suggestive findings of hypoechoic circumferential arterial wall thickening with perivascular fat infiltrations that are similar to the halo sign in large arteries but have not been reported in the breast. These are helpful for presumptive diagnosis of BV using ultrasound.

    @@ Cobb syndrome, also known as cutaneomeningospinal angiomatosis, is a rare clinical entity characterized by the combination of a vascular skin nevus and an angioma in the spinal canal at the same metamere.1 It was first described by Berenbruch in 1890 and did not receive recognition until Cobb's description2 in 1915. Only few documents about this disease had been reported.1 We present two cases here and review the other reported cases.

    Imaging findings of pulmonary Langerhans cell histiocytosis (PLCH) demonstrate evolving changes over time, and the radiological transitions shown by imaging tools may allow a prediction of histopathological activity in PLCH. However, there are no reports describing how rapidly CT findings change with time. We describe a case of PLCH that showed a rapid evolutional change of the pulmonary lesions in a 48-year-old man, in which the nodular lesions showed cystic changes within two-month follow-up periods on chest CT scans.

    Intramuscular myxomas are benign and rare tumors that affects predominantly the lower limbs. The association of myxomas and fibrous dysplasia, usually polyostotic, is rarer. This association is known as Mazabraud's syndrome, of which about 81 cases have been described in the literature. We present a new case of this uncommon association to emphasise the importance of recognizing this syndrome in the diagnosis and appropriate management of the patient.

    Full Text Available Head banging is a sleep-related rhythmic movement disorder of unknown etiology. It is common during infancy; however, available literature suggests that prevalence decreases dramatically after childhood. We report the case of a 16-year-old male who presented with head banging. The symptoms were interfering with his functioning and he had been injured because of the same in the past. We are presenting the video-polysomnographic data of the case. Possible differential diagnoses, etiology, and treatment modalities are discussed. The boy was prescribed clonazepam and followed up for 3 months. Parents did not report any episode afterward.

    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.

    "Pseudomembranous collagenous colitis" is a morphologic variant of collagenous colitis in which active inflammation with pseudomembrane formation is prominent and which has been associated with infectious, toxic, and ischemic etiologies. However, extracolonic morphologic findings in patients with pseudomembranous collagenous colitis have not been previously described. Here, we present a case of a patient with pseudomembranous collagenous colitis with abnormal extracolonic findings. These include gastric antral mucosa with histologic features reminiscent of ischemic injury and reactive gastropathy with intraepithelial lymphocytosis and partial villous atrophy in the duodenal and ileal biopsies. The findings in the small intestinal biopsies resemble those seen in enteric mucosa in patients with conventional collagenous colitis. Our pathologic findings as well as the clinical course of the patient further emphasize the clinical and histologic similarities shared by pseudomembranous collagenous colitis and conventional collagenous colitis.

    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.

    2007-02-01

    Full Text Available Abstract Background Atypical scrapie is a recently recognised form of transmissible spongiform encephalopathy of sheep that differs from classical scrapie in its neuropathological and biochemical features. Most cases are detected in apparently healthy sheep and information on the clinical presentation is limited. Case presentation This report describes the clinical findings in two sheep notified as scrapie suspects and confirmed as atypical scrapie cases by immunohistochemistry and Western immunoblotting. Although both sheep displayed signs suggestive of a cerebellar dysfunction there was considerable variation in the individual clinical signs, which were similar to classical scrapie. Conclusion Any sheep presenting with neurological gait deficits should be assessed more closely for other behavioural, neurological and physical signs associated with scrapie and their presence should lead to the suspicion of scrapie.

    Directory of Open Access Journals (Sweden)

    Bhakti D. Deshmukh

    2012-01-01

    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.

    2001-08-01

    We present a case of a 31 year-old male patient with tuberculous pericarditis with mediastinal mass that showed increased uptake on Gallium-67 image. Gallium-67 scan was performed to evaluate the activity of the superior mediastinal mass, which was detected on chest CT. A rim of Intense activity around the heart was observed, but increased uptake was not seen in the mediastinum. However, on maximal contrast-enhanced SPECT images, a small focus of faint uptake was observed in the superior mediastinum. This finding implied that there was an active tuberculosis in the pericardium and inflammation in the superior mediastinal mass. This case demonstrated that Gallium-67 scinitigraphy was helpful for the diagnosis of tuberculous pericarditis.

    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.

    Ischiogluteal bursitis is an uncommon disorder which can be confused with neoplastic conditions in the buttock. Three cases of ischiogluteal bursitis in a 57-year-old man, a 73-year-old woman and a 73-year-old man are presented. All patients presented with a gradually increasing, painful buttock mass. Magnetic resonance imaging (MRI) revealed a soft tissue mass around the ischial tuberosity and showed various features in the three cases. Two patients underwent excision of the lesion, which was histologically diagnosed as ischiogluteal bursitis. One patient was conservatively treated and the symptoms gradually decreased. MRI was very useful in diagnosing and detecting the lesion. Ischiogluteal bursitis should be considered in the differential diagnosis of a buttock mass.

    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)

  20. Prevalence of radiological findings among cases of severe secondary hyperparathyroidism

    Directory of Open Access Journals (Sweden)

    Paulo Gustavo Sampaio Lacativa

    Full Text Available CONTEXT AND OBJECTIVE: Patients with end stage renal disease (ESRD and secondary hyperparathyroidism (HPT2 are prone to develop heterotopic calcifications and severe bone disease. Determination of the sites most commonly affected would decrease costs and patients' exposure to X-ray radiation. The aim here was to determine which skeletal sites produce most radiographic findings, in order to evaluate hemodialysis patients with HPT2, and to describe the most prevalent radiographic findings. DESIGN AND SETTING: This study was cross-sectional, conducted in one center, the Hospital Universitário Clementino Fraga Filho (HUCFF, in Rio de Janeiro, Brazil. METHODS: Whole-body radiographs were obtained from 73 chronic hemodialysis patients with indications for parathyroidectomy due to severe HPT2. The regions studied were the skull, hands, wrists, clavicles, thoracic and lumbar column, long bones and pelvis. All the radiographs were analyzed by the same two radiologists, with great experience in bone disease interpretation. RESULTS: The most common abnormality was subperiosteal bone resorption, mostly at the phalanges and distal clavicles (94% of patients, each. "Rugger jersey spine" sign was found in 27%. Pathological fractures and deformities were seen in 27% and 33%, respectively. Calcifications were presented in 80%, mostly at the forearm fistula (42%, abdominal aorta and lower limb arteries (35% each. Brown tumors were present in 37% of the patients, mostly on the face and lower limbs (9% each. CONCLUSION: The greatest prevalence of bone findings were found on radiographs of the hands, wrists, lateral view of the thoracic and lumbar columns and femurs. The most prevalent findings were bone resorption and ectopic calcifications.

    Discussion and Conclusion: Although there is no classic ”carbon monoxide” ECG pattern, sinus tachycardia and ST-T depressions are the most common ECG findings. Even a small amount of exposure to CO can cause myocardial infarction, especially in patients with coronary artery disease. Patients admitting to ED with chest pain and ECG changes may be considered as a possible CO poisoning and patients with CO poisoning must be carefully evaluated for cardiovascular disease.

    Purpose: To retrospectively review CT and MRI findings in a series of six intraspinal primitive neuroectoderal tumors and to find out their radiological features. Methods: CT and MRI of six patients with surgically and pathologically proved intraspinal primitive neuroectoderal tumor were retrospectively reviewed. The tumor location, morphological features, signal intensity, calcification, contrast enhancement characteristics, involvement of paraspinal soft tissues and adjacent bony structures were assessed. Results: Of six patients, four had extradural lesions and two had intradural, extramedullary lesions. Most lesions were well defined and manifested heterogeneous iso- or hypo-intense signal on T1-weighted imaging and hyper-intense signal on T2-weighted imaging and moderate attenuation on CT, and were heterogeneously enhanced after contrast enhancement. The lesion extending through the intervertebral foramen with a large paraspinal soft tissue mass formed was found in four patients and vertebral bone involvement was seen in four patients. Conclusions: Although imaging findings are not specific of intraspinal primitive neuroectoderal tumor, this diagnosis could be suggested when MR imaging depicts an intradural, extramedullary or extradural large well-circumscribed mass which extends out from intervertebral foramen and invades paraspinal soft tissues or vertebral bones in a young patient.

    Desmoplastic fibroblastoma is a rare, fibrous, soft-tissue tumor that usually arises in subcutaneous tissues and skeletal muscle at various anatomic sites. We report a case of desmoplastic fibroblastoma in a 33-year-old female presented with a palpable mass in her right arm. Ultrasound images showed a hypoechoic mass lesion with internal vascularity. Magnetic resonance (MR) images showed areas of heterogeneously with high and low signal intensity on T2-weighted images, and intense enhancement on postcontrast T1-weighted images. Histopathologic examination of the resected specimen confirmed desmoplastic fibroblastoma

    The signal intensity of paranasal sinus mucocele is high variable, ranging from high to low on both T1-weighted and T2- weighted sequence. This variation is likely due to the combined effects of decreased free water concentration, cross-linking and polymerization of the macromolecular mucus glycoprotein, and increased viscosity. We have experienced three cases of the parenasal sinus mucocele with different signal intensity on Magnetic Resonance Imaging. We describe MR characteristics of the paranasal sinus mucocele and compare with MR characterises for other paranasal sinus diseases.

    We here describe a case of congenital leukemia that ended in intrauterine fetal demise at 30 weeks of gestation. Acute enlargement of the fetal trunk, elevated pulsatility index of the umbilical artery with concomitant decline of pulsatility index of the middle cerebral artery, pleural effusion, and polyhydramnios preceded the fetal death. Diagnosis of congenital myeloid leukemia was suggested by microscopic examination of the placental tissue, revealing immature myeloid precursors filling the lumina of fetal vessels in the umbilical cord and chorionic villi. Extensive vascular involvement of the placenta by leukemic cells was considered to be a primary cause of the fetal death.

    We describe two cases of primary thyroid lymphoma, involving 64-and 74-year-old women who presented with a rapidly growing palpable mass in the anterior neck. In both patients, plain radiographs of this region revealed tracheal displacement and soft tissue mass, and CT scans demonstrated the presence of a large soft tissue mass with homogeneously low attenuation, predominantly located in the unilateral lobe of the thyroid gland. Within the masses there was no calcification, necrosis, or hemorrhage, though in one patient the trachea was involved posteriorly by the mass Both masses appeared as cold nodules on RI scan, and in both patients, the final diagnosis was diffuse large cell type non-Hodgkin's lymphoma with a background of Hashimoto's thyroiditis.

    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.

    Because melanocytes are found throughout the leptomeninges, primary melanotic pigmented tumors such as pigmented meningioma, malignant melanoma, melanoblastosis, and melanocytoma can arise from this region. Melanocytomas have been described in the literature as isodense or hyperdense compared with brain parenchyme, as seen on noncontrast-enhanced CT, and as showing relatively homogeneous enhancement MR imaging demonstrates a high signal on T1-weighted images, and an iso to hypointense signal on T2-weighted images. We report the imaging findings of a melanocytoma that showed hyperdense attenuation on precontrast CT with homogeneous enhancement and hyperintense signal intensity on T1-weighted images and dark signal intensity enhancement on T2-weighted images, and also review the literature.

    Dental prosthesis is an uncommon ingested non-food foreign body in adults. Once swallowed, it can lead to serious complications and morbidity. Hence, early localization of the offending foreign body is crucial for timely management. As the dentures are usually made up of non-metallic material and often impacted at or below the level of C7 vertebra, conventional radiograph has limited role in their evaluation. We describe the clinical history and imaging findings of swallowed partial dentures in four patients who presented to the emergency department. The dentures were localized using unenhanced CT of the neck that showed the characteristic mildly hyperdense curvilinear or irregular appearance of the dentures within the upper esophagus. Multiplanar CT reconstructions provide an orientation of the ingested denture within the esophagus, thus guiding the endoscopist.

    Chronic ectopic pregnancy is an uncommon form of tubal pregnancy manifested as a pelvic mass with minimal symptoms and a low or absent titer of human chorionic gonadotropin. For this reason, most of the reported cases have been diagnosed only after explorative laparotomy. The value of Doppler ultrasonography for preoperative diagnosis of this entity has not yet been established. We report on a 36-year-old patient who was admitted for intermittent right lower quadrant abdominal pain of 3 months' duration, and a right adnexal mass found on pelvic examination. On Doppler ultrasonography, a right complex adnexal mass was demonstrated, characterized by extensive external vascularization, aberrant vessels and arteriovenous shunting, but with no internal blood flow. Explorative laparotomy revealed a right tubal mass adherent to the omentum, and covered by numerous enlarged and tortuous blood vessels originating in the omentum. Pathological examination of the mass revealed a chronic ectopic pregnancy. The possible contribution of Doppler-specific characteristics for the diagnosis of chronic ectopic pregnancy is described and 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.

    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.

    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.

    Surgery is one of the riskiest and most important medical acts that is performed today. Understanding the ways in which surgeries are similar or different from each other is of major interest to understand and analyze surgical behaviors. This article addresses the issue of identifying discriminative patterns of surgical practice from recordings of surgeries. These recordings are sequences of low-level surgical activities representing the actions performed by surgeons during surgeries. To discover patterns that are specific to a group of surgeries, we use the vector space model (VSM) which is originally an algebraic model for representing text documents. We split long sequences of surgical activities into subsequences of consecutive activities. We then compute the relative frequencies of these subsequences using the tf*idf framework and we use the Cosine similarity to classify the sequences. This process makes it possible to discover which patterns discriminate one set of surgeries recordings from another set. Experiments were performed on 40 neurosurgeries of anterior cervical discectomy (ACD). The results demonstrate that our method accurately identifies patterns that can discriminate between (1) locations where the surgery took place, (2) levels of expertise of surgeons (i.e., expert vs. intermediate) and even (3) individual surgeons who performed the intervention. We also show how the tf*idf weight vector can be used to both visualize the most interesting patterns and to highlight the parts of a given surgery that are the most interesting. Identifying patterns that discriminate groups of surgeon is a very important step in improving the understanding of surgical processes. The proposed method finds discriminative and interpretable patterns in sequences of surgical activities. Our approach provides intuitive results, as it identifies automatically the set of patterns explaining the differences between the groups. Copyright © 2017 Elsevier B.V. All rights

    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

    Epithelioid angiomyolipoma (EAML) is an uncommon, variant type of angiomyolipoma with a possibility of metastatic transformation and distant spread. Angiomyolipomas, including epithelioid variant type, are mostly renal in origin. EAML originating from extrarenal location is very rare and imaging findings are not well described. Herein, we reported a very rare case of EAML arising from the perirenal space that mimicked a malignant retroperitoneal tumor, in a 39-year-old female.

  4. Chandra Finds Surprising Black Hole Activity In Galaxy Cluster

    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

    Two cases of mucocele of the paranasal sinuses are reported. The first case is a mucocele of the right ethmoidal sinus with bone destruction in a 60-year-old woman, whose radiographic findings were simulating those of maxillary cancer. The second case is a mucocele of the sphenoid sinus in a 78-year-old woman. In the radiographic findings, it appeared that the lesion had extended into the intracranial space. Both cases were treated successfully by intranasal ethmoidectomy.

    Full Text Available Kawasaki disease is a multisystemic vasculitis of pediatric age group. Early diagnosis and treatment is crucial as coronary artery aneurysms may develop in 20-25% of untreated cases in the 2nd-3rd weeks of the disease. The most common urinary finding in the active period is sterile pyuria; which is believed to be a sign of a more severe systemic inflammation. In this study, a 3.5 year old boy who admitted with high fever was presented. As he had pyuria and elevated acute phase reactants, antibiotic treatment was started with a pre-diagnosis of acute pyelonephritis. Later, with the persistence of fever, detection of a negative urine culture result and emergence of dermal, mucosal and conjunctival changes, incomplete Kawasaki disease (KD was diagnosed. In conclusion, it should be remembered that prolonged fever with sterile pyuria can be the initial findings in KD; before the emergence of typical lesions.

    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.

    High proportion of TB in people living with HIV (PLHIV) is undiagnosed. Due to this active TB case finding is recommended for HIV clinics in high TB burden countries. Presently sputum examination and chest radiography are frontline tests recommended for HIV infected TB presumptives. Abdominal TB which occurs frequently in PLHIV may be missed even by existing programmatic intensified case finding protocols. This study evaluated the routine use of ultrasonography (USG) for active case finding of abdominal TB in HIV clinics. Retrospective analysis of eight years' data from an HIV Clinic in a TB hospital in India. Patients underwent chest x-ray, sputum examination, USG abdomen and routine blood tests at entry to HIV care. Case forms were scrutinized for diagnosis of TB, USG findings and CD4 cell counts. Abdominal TB was classified as probable or possible TB. Probable TB was based on presence of two major USG (abdomen) findings suggestive of active TB, or one major USG finding with at least two minor USG findings or at least two symptoms, or any USG finding with microbiologically confirmed active TB at another site. Possible TB was based on the presence of one major USG finding, or the presence of two minor USG findings with at least two symptoms. Bacteriological confirmation was not obtained. Eight hundred and eighty-nine people PLHIV underwent a baseline USG abdomen. One hundred and thirteen of 340 cases already diagnosed with TB and 87 of the 91 newly diagnosed with TB at time of HIV clinic registration had abdominal TB. Non-abdominal symptoms like weight loss, fever and cough were seen in 53% and 22% cases had no symptoms at all. Enlarged abdominal lymph nodes with central caseation, ascitis, splenic microabsesses, bowel thickening and hepatosplenomegaly were the USG findings in these cases. Abdominal TB is a frequent TB site in PLHIV presenting with non-abdominal symptoms. It can be easily detected on basis of features seen on a simple abdominal ultrasound

    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.

    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...

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 among tested social mechanisms. Our observation also suggests that people who connect different communities is more likely to be an influential spreader when a network has a strong modular structure. Our finding implies that not only the effect of network location but also the behavior of individuals is important to design optimal immunization or spreading schemes.

    The objective of this study was to characterize the clinical, clinicopathological, and histopathological findings of dogs with chronic pancreatitis. The necropsy database at Texas A&M University was searched for reports of dogs with histological evidence of chronic pancreatitis defined as irreversible histologic changes of the pancreas (i.e. fibrosis or atrophy). A reference necropsy population of 100 randomly selected dogs was used for signalment and concurrent disease comparisons. Cases were categorized as clinical or incidental chronic pancreatitis based on the presence of vomiting, decreased appetite, or both vs. neither of these signs. All archived pancreas samples were scored histologically using a published scoring system. Sixty-one dogs with chronic pancreatitis were included. The most frequent clinical signs were lethargy, decreased appetite, vomiting, and diarrhea. Compared to the reference necropsy population, chronic pancreatitis cases were more likely to be older, neutered, of the non-sporting/toy breed group, and to have concurrent endocrine, hepatobiliary, or neurological disease. Clinical cases had significantly higher histological scores for pancreatic necrosis and peripancreatic fat necrosis, and were significantly more likely to have hepatobiliary or endocrine disease as well as increased liver enzyme activities, or elevated cholesterol and bilirubin concentrations. In conclusion, clinical disease resulting from chronic pancreatitis might be related to the presence of pancreatic necrosis and pancreatic fat necrosis. The signalment, presentation, and concurrent diseases of dogs with chronic pancreatitis are similar to those previously reported for dogs with acute pancreatitis.

    Three out-patient antenatal care (ANC) clinics in Lusaka, Zambia. To estimate tuberculosis (TB) prevalence in human immunodeficiency virus (HIV) infected and symptomatic, non-HIV-infected pregnant women and explore the feasibility of routine TB screening in ANC settings. Peer educators administered TB symptom questionnaires to pregnant women attending their first ANC clinic visit. Presumptive TB patients were defined as all HIV-infected women and symptomatic non-HIV-infected women. Sputum samples were tested using smear microscopy and culture to estimate TB prevalence. All 5033 (100%) women invited to participate in the study agreed, and 17% reported one or more TB symptoms. Among 1152 presumed TB patients, 17 (1.5%) had previously undiagnosed culture-confirmed TB; 2 (12%) were smear-positive. Stratified by HIV status, TB prevalence was 10/664 (1.5%, 95%CI 0. 7-2.8) among HIV-infected women and 7/488 (1.4%, 95%CI 0.6-2.9) among symptomatic non-HIV-infected women. In HIV-infected women, the only symptom significantly associated with TB was productive cough; symptom screening was only 50% sensitive. There is a sizable burden of TB in pregnant women in Zambia, which may lead to adverse maternal and infant outcomes. TB screening in ANC settings in Zambia is acceptable and feasible. More sensitive diagnostics are needed.

    Since the 1980s, schools have been recognized as an ideal setting to promote students' and teachers' health. Three decades after the development of the Health Promoting Schools (HPS) approach, however, there is still only limited knowledge about the implementation of health promotion (HP) activities in this setting. Some studies indicate that schools change original concepts significantly when adapting them to local context in the course of implementation. In this paper, we pursue the question how HP is practiced in schools that have agreed to implement HPS concepts from regional service providers (SPs), using data from a multiple-case study conducted in an Austrian province. Furthermore, we explored the HP activities chosen for implementation and the decision-making leading to their implementation. We draw on 22 interviews with members of the school community and provincial HP SPs, 9 group discussions, and 10 observations we have carried out within three schools between November 2010 and January 2012, supplemented by a variety of documents. We have identified 40 different HP activities, of which most targeted students, while mostly focusing on physical activity and/or psychosocial health. Planning, coordination and cooperation at the school level were minimal. Decisions for or against activities were seldom taken together, but taken individually due to personal knowledge, interests and experiences, perceived needs and problems, already existing activities and external influences. The findings suggest that schools rather remain with a traditional topic-based approach instead of realizing an integrated whole-school approach and indicate a need for more support especially during the early phases of implementation. © The Author 2014.

    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.

    Ganglion cell tumors of the central nervous system (CNS) are uncommon. 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

    Cytokine storm-derived influenza-associated encephalopathy is a severe complication, affecting not only the brain but also multiple systemic organs including the heart and lungs. Hundreds of Japanese children are afflicted by influenza-associated encephalopathy every year. Influenza-associated encephalopathy can be diagnosed by pathological changes, such as advanced brain edema and disruption of astrocytic projections, which is known as clasmatodendrosis. In the present case, despite the absence of significant histopathological findings in the brain, the diagnosis of influenza-associated encephalopathy was made on the basis of autopsy findings such as brain swelling, pathological findings including diffuse alveolar damage, and increase in the concentrations of interleukin-6 in both the serum and cerebrospinal fluid. In this case, the interval from high fever to death was approximately 7 hours and may have been too short for histopathological features to develop. This is an unusual autopsy case of cytokine storm-derived influenza-associated encephalopathy without typical histopathological 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.

    Sacral agenesis (or caudal regression syndrome) is a rare congenital anomaly involving various levels of coccygeal, sacral, and even lumbar or lower thoracic vertebral dysgenesis, as well as spinal cord abnormalities. A few cases have been previously reported in Korea, especially based upon MRI findings. We describe a case of a 4-year-old girl with partially bilateral agenesis of the sacrum (type II), and club-shaped (chisel-shaped) spinal cord disruption. We also review MRI findings of sacral agenesis, focused on classification and radiological findings.

    2012-06-01

    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.

    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.

    Brachialis periosteal avulsion injury is an uncommon injury occurring in young children. The injury may be misinterpreted or overlooked because of misleading or subtle radiological findings. A case of 7-year-old child with post-traumatic elbow pain and subtle findings on elbow radiography is presented. The injury was initially misinterpreted as an avulsion fracture of the medial epicondyle. Following radiological review, a diagnosis of brachialis periosteal avulsion injury was made. The radiographic and magnetic resonance imaging (MRI) findings of this injury are presented to stress the value of comparing the radiographic findings with previous imaging and to increase awareness of this uncommon injury.

    Full Text Available OBJECTIVE To study the histopathological lesions of Heart in cases of sudden death. METHOD During the period from 1st July 2014 to 30 November 2015, out of 144 medicolegal autopsies, 120 autopsies of heart were received. Five specimen of heart were autolyzed so 115 autopsy specimen of heart were included for study. Routine H and E staining is used for microscopic examination. RESULT Out of 115 cases, 74 cases shows atherosclerosis, 33 cases shows features of myocardial infarction, myocardial hypertrophy found in 60 cases, 11 cases shows myocarditis, vaso-occlusive crisis in sickle cell was present in 6 cases and pericarditis present in 1 case. In 29 cases, there was no identifiable cause of death even after complete gross and microscopic autopsy was performed. CONCLUSION It was concluded that myocardial infarction due to atherosclerotic ischaemic heart disease is probably the commonest diagnosis made in majority of sudden death cases subjected to medicolegal autopsies. Histological findings must be evaluated with great attention for preventing incorrect conclusion to identify causes of deaths in sudden death cases.

    Limited information exists on the prevalence of tuberculosis and adequacy of case finding in African populations with high rates of HIV. To estimate the prevalence of bacteriologically confirmed pulmonary tuberculosis (PTB) and the fraction attributable to HIV, and to evaluate case detection. Residents aged 15 years and older, from 40 randomly sampled clusters, provided two sputum samples for microscopy; those with chest radiograph abnormalities or symptoms suggestive of PTB provided one additional sputum sample for culture. PTB was defined by a culture positive for Mycobacterium tuberculosis or two positive smears. Persons with PTB were offered HIV testing and interviewed on care-seeking behavior. We estimated the population-attributable fraction of HIV on prevalent and notified PTB, the patient diagnostic rate, and case detection rate using provincial TB notification data. Among 20,566 participants, 123 had PTB. TB prevalence was 6.0/1,000 (95% confidence interval, 4.6-7.4) for all PTB and 2.5/1,000 (1.6-3.4) for smear-positive PTB. Of 101 prevalent TB cases tested, 52 (51%) were HIV infected, and 58 (64%) of 91 cases who were not on treatment and were interviewed had not sought care. Forty-eight percent of prevalent and 65% of notified PTB cases were attributable to HIV. For smear-positive and smear-negative PTB combined, the patient diagnostic rate was 1.4 cases detected per person-year among HIV-infected persons having PTB and 0.6 for those who were HIV uninfected, corresponding to case detection rates of 56 and 65%, respectively. Undiagnosed PTB is common in this community. TB case finding needs improvement, for instance through intensified case finding with mobile smear microscopy services, rigorous HIV testing, and improved diagnosis of smear-negative TB.

    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

  20. Consolidating findings from business process change case studies using system dynamics: The example of employee morale

    Directory of Open Access Journals (Sweden)

    Zuzana Kristekova

    2012-12-01

    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.

  1. A Rare Case of Invasive Apocrine Carcinoma of the Breast with Unusual Radiologic Findings

    Directory of Open Access Journals (Sweden)

    2016-05-01

    Full Text Available Invasive apocrine carcinoma (IAC of the breast is a rare subtype of breast malignancy. Its incidence is not well known, but it is approximately less than 1% to 4%. For these reasons, there are few reports and little information on the radiologic appearance of IAC. Furthermore, most of the case reports show malignant features which are similar to invasive ductal carcinoma (IDC. We present a rare case of IAC without typical malignant feature on mammography, and ultrasonography (USG. Imaging findings on computed tomography (CT, magnetic resonance imaging (MRI, and 18F-fluorodeoxyglucose (FDG positron emission tomography (PET/CT are also presented. The nodule in our case showed a relatively benign feature on USG and it is the first case of IAC with unusual findings. Therefore, this report may encourage radiologists to consider the malignant potential and perform pathologic correlation even if a newly developed nodule does not present with a typical malignant feature on USG.

    Primary breast melanoma is extremely rare, and as such, there are no established radiologic findings in the literature. This report describes a case of primary malignant melanoma with mammography, ultrasonography, and magnetic resonance imaging findings. Our case study demonstrates a well-circumscribed heterogeneous rim-enhancing mass, with an internal cystic or necrotic portion seen using three modalities. Thus, although rare, this condition should be included in the differential diagnosis of a well-demarcated heterogeneous breast mass, and further pathological confirmation is needed.

    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.

    This case report illustrates the potential fallacy of attributing a patient's symptoms to an incidental finding. Serial imaging of small, asymptomatic cerebellopontine angle (CPA) lipomas is favored. It is imperative to accurately diagnose CPA lipoma on imaging and differentiate it from more common CPA lesions. We herein present a patient with symptoms consistent with Bell's palsy and an incidental finding of a CPA lipoma. Additionally, we performed a review of the literature for case reports of patients presenting with facial symptoms and diagnosed with a CPA lipoma.

    We report on the MR imaging findings in a case of spinal desmoplastic fibroma (DF). DF of the bone is a rare, locally aggressive tumor. It is commonly located in long bones, pelvis or mandible. DF involving the spine is extremely rare and difficult to distinguish from other bony lesions such as giant cell tumor, chordoma and fibrous dysplasia of the spine. This case of DF of the spine showed MR findings similar to those of DF arising in the metaphysis of a long bone.

    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 Patients with autoimmune conditions develop lymphoproliferative disorders (LPDs at a higher frequency than normal both in association with and independent of Methotrexate (MTX. We describe a case of MTX-associated lymphoma in a patient with psoriasis on long-standing MTX. The case is notable for the initial tumor burden, the dramatic disappearance of the PET-CT findings on discontinuation of MTX, and the subsequent early regrowth of disease. Our case report is illustrative of an MTX-related NHL in an autoimmune patient. Conclusion. Withdrawal of MTX in a patient with lymphoma is reasonable before initiating chemotherapy, but observation for early regrowth of disease is necessary.

    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.

    Uterine tumor resembling ovarian sex-cord tumor is a very rare uterine neoplasm that was first described by Clement and Scully in 1976. Since then, approximately 70 cases have been reported. However, these case reports have mainly described and discussed the pathologic and clinical features, and few radiologic findings have been presented. We experienced a case of a uterine tumor resembling ovarian sex-cord tumor, which was considered a uterine leiomyoma or leiomyosarcoma upon initial impression at preoperative evaluation including transvaginal ultrasonography and pelvic magnetic resonance imaging. Its diagnosis was pathologically confirmed after total abdominal hysterectomy.

    Fibromatosis is a rare benign neoplasm that appears as a sporadic lesion or is found in patients with familial adenomatous polyposis. Fewer than 7 cases of intraabdominal solitary fibromatosis arising from the colon have been reported in the English literature. This small number of reported cases may be not only because of the low incidence of the disease but also because of the difficulty in making proper diagnosis. We present here a case of histologically confirmed intraabdominal solitary fibromatosis arising from the colon, with an emphasis on computed tomography findings.

    Intrapulmonary solitary fibrous tumor is extremely rare. A few reports have presented typical CT findings such as well-defined, variable—sized, heterogeneously or homogenously well-enhanced intrapulmonary nodules. We report herein a rare case of intrapulmonary solitary fibrous tumor that showed typical clinical and CT features, and we also provide an ancillary CT finding that shows a distinguishable tubular vascular structure within the nodule. The tubular vascular structure was conjoined to the proximal pulmonary vein. In this study, we highlight an ancillary CT finding reported for the first time for the diagnosis of a patient with intrapulmonary solitary fibrous tumor.

    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.)

    Tolperisone (Mydocalm) is a centrally acting muscle relaxant with few sedative side effects that is used for the treatment of chronic pain conditions. We describe three cases of suicidal tolperisone poisoning in three healthy young subjects in the years 2006, 2008 and 2009. In all cases, macroscopic and microscopic autopsy findings did not reveal the cause of death. Systematic toxicological analysis (STA) including immunological tests, screening for volatile substances and blood, urine and gastric content screening by GC-MS and HPLC-DAD demonstrated the presence of tolperisone in all cases. In addition to tolperisone, only the analgesics paracetamol (acetaminophen), ibuprofen and naproxen could be detected. The blood ethanol concentrations were all lower than 0.10 g/kg. Tolperisone was extracted by liquid-liquid extraction using n-chlorobutane as the extraction solvent. The quantification was performed by GC-NPD analysis of blood, urine and gastric content. Tolperisone concentrations of 7.0 mg/l, 14 mg/l and 19 mg/l were found in the blood of the deceased. In the absence of other autopsy findings, the deaths in these three cases were finally explained as a result of lethal tolperisone ingestion. To the best of our knowledge, these three cases are the first reported cases of suicidal tolperisone poisonings.

Les augmentations ont également été plus importantes chez les enfants de 0 à 4 ans et chez ceux qui ont eu une TB pulmonaire à frottis négatif et extra-pulmonaire. Parmi diverses stratégies de recherche des cas, le dépistage des contacts familiaux, les services conjoints privés-publics et les camps de santé mobiles pour la TB ont été les plus performants.Conclusion : Un paquet de stratégies intensifiées de recherche des cas a été associé à une augmentation des enregistrements de cas de TB de l'enfant au Népal. Il faut également envisager des approches diagnostiques supplémentaires pour augmenter encore l'enregistrement des cas.

    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.

    2006-12-01

    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 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.

    Begun in 2005, the Building Strong Geoscience Departments project sought to help geoscience departments respond to changes in geosciences research, academic pressures, and the changing face of the geosciences workforce by working as a team, planning strategically, and learning from the experiences of other geoscience departments. Key strategies included becoming more central to their institution's mission and goals; articulating the department's learning goals for students; designing coordinated curricula, co-curricular activities, and assessments to meet these goals; and recruiting students effectively. A series of topical workshops identified effective practices in use in the U.S. and Canada. These practices were documented on the project website and disseminated through a national workshop for teams of faculty, through activities at the AGU Heads and Chairs workshops, and in a visiting workshop program bringing leaders to campuses. The program has now involved over 450 participants from 185 departments. To understand the impact of the program, we engaged in ongoing discussion with five departments of various sizes and institutional types, and facing a variety of immediate challenges. In aggregate they made use of the full spectrum of project offerings. These departments all reported that the project brought an important new perspective to their ability to work as a department: they have a better understanding of how their departments' issues relate to the national scene, have more strategies for making the case for the entire department to college administrators, and are better poised to make use of campus resources including the external review process. These results were consistent with findings from end-of-workshop surveys. Further they developed the ability to work together as a team to address departmental challenges through collective problem solving. As a result of their workshop participation, two of the departments who considered their department to be

    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.

    Full Text Available Fluid collections are common findings of pancreatitis and spread, more often, along preferential drainage pathways in the abdomen. In some rare cases, fluid collections may spread towards extra-abdominal sites like the mediastinum leading to the formation of mediastinal collections. We present the case of a 52-years-old man with pain in the right upper quadrant of the abdomen and mid-epigastrium lasting for some hours. Laboratory tests suggested a diagnosis of pancreatitis. CT and subsequent MRI revealed changes consistent with acute exacerbation on chronic pancreatitis spreading to the mediastinum and to the greater omentum. The patient received medical treatment and reported gradual improvement in his laboratory results and CT findings.

    Pseudoangiomatous stromal hyperplasia (PASH), a rare benign lesion, shows the proliferation of the breast stromal tissue mimicking the low grade angiosarcoma (1-7). The most common mammographic and ultrasound finding of PASH is a circumscribed mass without calcification and it is difficult to distinguish from the phyllodes tumor and fibroadenoma (1-4, 8). Up to our knowledge, PASH presenting as rapid bilateral breast enlargement, as seen in our case, is very rare. In addition, several English medical literature were reported in this kind of manifestation of PASH (3, 4, 8). We described imaging findings of diffuse, infiltrating, and bilateral manifectation of PASH.

    It may lead to symptoms presenting with an acute onset or to chronic and nonspecific complaints. As the presentation is often similar to other pathologies (acute appendicitis, pancreatitis, or acute cholecystis and in many cases diagnosis is made on basis of surgical findings, careful analysis of the imaging landmarks may be warranted to aid in the early stages of detection. In this report, we present clinical and morphological findings in three patients where small-bowel diverticulitis was surgically proven. The relevant literature is reviewed, and typical imaging properties are discussed.

    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.)

    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.

    Unilateral pulmonary artery hypoplasia or agenesis without congenital cardiovascular anomalies is rare in adults. We report a case of a 36-year-old man with isolated left unilateral pulmonary artery hypoplasia with recurrent hemoptysis. On computed tomography (CT), the left pulmonary artery showed hypoplasia with multiple collateral vessels seen in the mediastinum and the left hemithorax. Also, parenchymal bands and peripheral linear opacities were seen in the affected lung, which were probably due to chronic infarction induced by unilateral pulmonary artery hypoplasia. There are only a few reports focusing on the radiologic findings in the pulmonary parenchyma induced by unilateral pulmonary artery hypoplasia, such as parenchymal bands and peripheral linear opacities. Therefore we report this case, which focused on the CT findings in the pulmonary parenchyma due to isolated unilateral pulmonary artery hypoplasia.

    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)

    Gorlin-Goltz syndrome is an infrequent multi-systemic disease which is characterized by multiple keratocysts in the jaws, calcification of falx cerebri, and basal cell carcinomas. We report a case of Gorlin-Goltz syndrome in a 23-year-old man with emphasis on image findings of keratocyctic odontogenic tumors (KCOTs) on panoramic radiograph, computed tomography, magnetic resonance (MR) imaging, and Ultrasonography (US). In this case, pericoronal lesions were mostly orthokeratinized odontogenic cyst (OOC) concerning the MR and US study, which tended to recur less. The aim of this report was to clarify the characteristic imaging features of the syndrome-related keratocysts that can be used to differentiate KCOT from OOC. Also, our findings suggested that the recurrence rate of KCOTs might be predicted based on their association to teeth.

    As a part of a comprehensive programme of tuberculosis (TB) control in the central prison in Qazvin, Islamic Republic of Iran, a programme of active case-finding was carried out from February 2004 to July 2005. From the 768 prisoners examined, 41 (5.3%) were suspected of TB and gave sputum samples. A total of 7 smear-positive TB cases were found, giving a TB prevalence in the prison of 910 per 100,000, 113 times the total TB prevalence in Qazvin province in the same year. From 7 diagnosed and treated patients, 4 were cured with the category 1 standard regimen, 1 completed treatment and 2 failed to complete treatment. Improvements are needed in TB case recognition of prisoners, especially newcomers.

    Florid cemento-osseous dysplasia (FCOD) is a benign jaw lesion originating from periodontal ligament tissues usually asymptomatic and diagnosed accidentally at routine dental radiographic examination. The purpose of this paper is to report three cases diagnosed as FCOD with their clinical, radiographic and histological findings. Radiologic and clinical symptoms of three cases diagnosed as FCOD are presented. Serum alkaline phosphatase test and biopsy taken from two of the patients are discussed to eliminate the Paget's disease. Three patients diagnosed as FCOD and called for routine follow-up. Because of no sign of infection or osteomyelitis, conservative treatment was applied. Radiographic examination is significant for the diagnosis of florid cemento-osseous dysplasia, especially in the asymptomatic cases. The roles of the dentist are to ensure the follow-up of the diagnosed patients and to take the necessary measures for preventing from the infections.

    Cerebral angiograms of 34 patients with childhood moyamoya disease have been analysed, this analysis having revealed the following findings. The blood flow to abnormal net-like vessels (ANV) in the base of the brain is mainly supplied from the internal carotid artery (ICA) in the early stage of this disease. In a later stage, however the blood supply is mainly from the posterior cerebral artery (PCA). Though, no remarkable change was found in the volumes of ANV from the early to later stages of the disease, the leptomeningeal collaterals, the most prominent anastomoses in moyamoya disease, had a tendency to decrease during the later stage with the development of PCA stenosis. Eighteen occlusive PCA lesions were found in the proximal portion of the PCA in eight cases (44%), and in the distal in nine cases (50%). The incidence of aneurysm (1.5%) and intracranial bleeding was low as compared to cases of adult moyamoya disease.

    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.

    To determine the prevalence of various lesion types detected by histologic evaluation of uterine biopsy samples collected from subfertile bitches. Retrospective case series. 399 sexually intact bitches. Results of histologic evaluation of canine uterine biopsy samples submitted by a single veterinary practice and clinical histories of dogs from which samples were obtained were reviewed. Clinical data including age, reason for biopsy, and histopathologic findings were recorded. The prevalence of specific lesions was determined, categorized by severity and age, and statistically analyzed. Endometritis (170/399 [42.6%] cases) and cystic endometrial changes, including cystic endometrial hyperplasia (133/399 [33.3%]) were the most prevalent lesions in the study population. Eighty-nine of 170 (52.4%) cases of endometritis were characterized as chronic with predominantly lymphocytic or lymphoplasmacytic inflammatory infiltrates, 51 (30.0%) included mixed inflammatory reactions, and 30 (17.6%) were characterized as having acute inflammation with neutrophils, eosinophils, or both. Fibrosis was common (101/399 [25.3%] cases). Eosinophilic endometritis was significantly associated with a history of fetal loss during the same breeding cycle. No significant difference was found in prevalence of lesions among age groups. The high prevalence of endometritis in this population of dogs suggested that acute and chronic endometritis may be related to subfertility in bitches. The association of eosinophilic endometrial infiltrates with a history of fetal loss may be an important diagnostic finding in dogs with endometritis.

    Three cases of neuroblastoma with intracranial metastases were reported. The first case was a 13-year-old girl with sacral neutroblastoma who had metastases to the left parietal bone and dura, and had bilateral intraorbital metastases. The second case was a 13-year-old girl with mediastinal neutroblastoma who had metastases to the dura at the left middle fossa, and had bilateral intraorbital metastases. The third case was a 49-year-old woman with esthesioneuroblastoma which had invaded to the dura at the right middle fossa and the right orbit. CT findings of the brain of these three cases were investigated, and summarized as follows: 1) The intracranial invasions of the metastatic tumors were seen to be slightly high density (EMI-number 25 - 27) in plain scans, and homogeneously enhanced as a well-defined high density mass (EMI-number 35 - 37). 2) The tumors invading the skull were observed as a mass lesion of the bone on osteolytic lesion. 3) The intraorbital metastatic tumors were seated on the orbital wall invading the rectal muscles, but they remained extraconal. It was emphasized that CT could give valuable information for the diagnosis of skull and intracranial metastasis of neutroblastoma.

    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.

    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.

    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.

    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

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

    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

    To assess the influence of subjective word-finding difficulty on degree of engagement in social leisure activities among individuals with Alzheimer's disease (AD). Analysis of data collected from the second cohort of the Multicenter Study of Predictors of Disease Course in Alzheimer's disease. Four study sites in the United States and France. Individuals diagnosed with mild to moderate AD (N = 236). On separate questionnaires, participants were asked to 1) report whether they had trouble finding the right word when speaking (subjective word-finding difficulty) and 2) rate their frequency and enjoyment of social and nonsocial leisure activities. Objective language measures included object naming and verbal fluency. Measures of dependence, depression, cognitive status, age, sex, and education were also included as covariates in regression analyses. Fifty-two percent of the sample reported word-finding difficulty, and subjective complaints were correlated with poorer verbal fluency scores. Subjective word-finding difficulty was selectively related to social but not nonsocial activity measures. Endorsers of word-finding difficulty reported less frequency and enjoyment of social leisure activities, controlling for effects of covariates and objective word-finding ability. In contrast, lower engagement in nonsocial activities was associated with older age and higher depression scores but not with word-finding complaints. Caregivers' reports of study participants' activities corroborated these results. Individuals with AD who are aware of increasing word-finding failures are less likely to participate in and enjoy socially oriented leisure activities. This finding may have significant implications for clinical and health outcomes in AD. Failure to evaluate subjective language complaints could result in social withdrawal symptoms, threatening the individual's quality of life and increasing caregiver burden. Reduced social interaction may ultimately exacerbate language

    Background. Chronic lymphocytic thyroiditis is the second most common thyroid lesion diagnosed on FNAC after goiter. FNAC is reliable tool in the diagnosis of thyroid lesion. Objective. To correlate FNAC cytologic findings with TFT in the lymphocytic thyroiditis. Methods. 175 patients with thyroid swellings were referred for FNAC as well as TFT during 2011-2013. Fine needle aspiration cytology was performed using non-aspiration or aspiration techniques and TFT performed on Beckman culter access 2. Results. Lymphoid infiltrate was seen in 55 cases. The commonest age group of lymphocytic thyroiditis was 21-30 years with male : female ratio being 1 : 10. Anti-TPO and TSH were elevated in 96.16% (25/26) of cases with grade 3 lymphoid infiltrate, 94.12% (16/17) of cases with grade 2, and 91.67% (11/12) of cases with 1 grade. Increased anti-TPO with raised TSH without any lymphoid infiltrate was seen in 5 cases and 5 cases showed only raised TSH without raised anti-TPO and without any lymphoid infiltrate. We observed that grade 3 lymphocytic infiltration has correlation with anti-TPO and TSH together or TSH alone but not with anti-TPO alone. We also observed that anti-TPO and TSH together are significant even if no lymphocytic infiltration is present. Conclusion. Grade 3 lymphocytic infiltration has statistical correlation with anti-TPO and TSH together or TSH alone but not with anti-TPO alone. Anti TPO was adjunct to TSH in grade 3. The presence of Hurthle cell change, giant cells, and granulomas has no statistical correlation with lymphocytic thyroiditis.

    Full Text Available Abstract Introduction Hydrochlorothiazide and thiazide-like diuretics are considered first-line drugs for initial therapy in uncomplicated arterial hypertension. Acute cholecystitis is a well-known complication during treatment with thiazide, and these drugs are also reported to be followed by pronounced insulin resistance. Case presentation We describe a case of acute cholestatic hepatitis in a 68-year-old Caucasian man who was receiving olmesartan and hydrochlorothiazide for arterial hypertension. From the clinical and histologic findings, we diagnosed him as having hepatocellular-cholestatic injury and a disorder of glucose metabolism in the liver. To the best of our knowledge, no histopathologic description of hydrochlorothiazide hepatotoxicity has previously been documented in the literature. Conclusion In the differential diagnosis of cholestatic hepatitis, clinicians should be aware of the possibility of liver damage in patients receiving hydrochlorothiazide therapy.

    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.

    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.

    Lower extremity infection caused by Vibrio vulnificus sepsis is a rapidly progressing fatal condition. Prompt diagnosis followed by early and aggressive treatment with antibiotics and fasciotomy is crucial. In this report, we described lower extremity magnetic resonance (MR) images of three patients with Vibrio vulnificus sepsis. In our cases, MR imaging of lower extremity with Vibrio vulnificus sepsis showed three common findings. First, the MR signal abnormalities appeared simultaneously in all layers, including skin, subcutaneous fat, muscles, and deep fasciae. Second, the inflammation showed symmetry on both legs. Third, none of our cases was accompanied by abscess formation. These imaging features may represent rapid progression of Vibrio vulnificus sepsis and could be helpful for accurate diagnosis, and prompt and aggressive treatment.

    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.

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

    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.

    A 50-year-old male was diagnosed to have a right eye sclerouveitis and left eye granulomatous anterior uveitis due to Hansen's disease. We are reporting the anterior segment optical coherence tomography (ASOCT) findings of iris granuloma in this case. Skin biopsy revealed plenty of acid fast bacilli with a bacteriological index of 5 suggestive of multibacillary polar lepromatous leprosy. ASOCT revealed well-demarcated smooth-surfaced nodular lesion with internal hyporeflectivity corresponding to the areas of granuloma which decreased in size following treatment with antileprosy drugs and systemic and topical steroids. ASOCT is a non-invasive technique to assess the extent of involvement of anterior segment in Hansen's disease and is a useful tool in follow-up. This is also the first report on ASOCT findings of iris granuloma in Hansen's disease.

    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.

    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.

    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.

    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.

    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 West syndrome a rare, severe form of epilepsy occurs in early infancy. It is characterized by a triad consisting of infantile spasms that occurs in clusters, arrest of psychomotor development and hypsarrhythmia on electroencephalogram. We present here two cases of west syndrome where patients required dental care due to the presence of certain dental findings. Preventive measurements such as controlled diet and proper oral hygiene along with professional dental management are recommended in patients with west syndrome to avoid dental problems.

    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.

    Herpes simplex virus (HSV) type I causes a fulminant necrotising meningoencephalitis distinguished from other encephalitides by its focal and often haemorrhagic nature. Specific antiviral therapy with acyclovir can significantly improve the prognosis. We present MRI findings of two cases of herpes simplex encephalitis (HSE) confirmed by PCR analysis, focusing on the serial changes after acyclovir therapy: gyral swelling, high signal intensity on T2-weighted images in the subfrontal region, temporal lobe and insula in the initial stage, then regional extension with enhancement and haemorrhage despite appropriate acyclovir therapy, and finally encephalomalacia and brain atrophy.

    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.

    Full Text Available The spectrum of lipomatous lesions ranges from benign to highly malignant disease. Differentiation between these lesions is important to indicate prognosis and choose the most appropriate treatment. Hemosiderotic fibrohistiocytic lipomatous lesion (HFLL is a rare subtype of lipomatous tumor. The diagnosis is usually based on clinical, histological, and immunohistochemical information. Where magnetic resonance (MR imaging is a suitable modality to assess fatty tumors, no data is reported on MR imaging of HFLL. Here, the MR characteristics are described in correlation with pathologic findings in a case of HFLL in the left thigh, an unusual location.

    Liver infarction is relatively uncommon. It may be secondary to several conditions such as sepsis, shock, sickle-cell anaemia, eclampsia, vasculitis, metastatic disease, bacterial endocarditis, rheumatic heart disease, trauma, portal venous occlusion or compression, oral contraception, anaesthesia, hepatic artery thrombosis, therapeutical or inadvertent hepatic artery ligation, intra-arterial chemotherapy or embolisation. A case of hepatic infraction, unusual for iatrogenic pathogenesis, submassive extension with acute hepatic failure, and CT findings of an internally branching pattern due to intravascular gas was observed.

    Primary localized amyloidosis is a rare disease that impairs the organs and tissue function, caused by extracellular deposition of amyloid protein. Although amyloid proteins can be deposited in localized or systemic organs, the bladder is a rare site. CT showed diffuse infiltrative mass in the left urinary bladder wall, and the left ureterovesical junction with enhancement and perivesical invasion, which mimics urothelial carcinoma. However, pathological diagnosis was localized primary amyloidosis. We report here on the CT findings of a rare case of primary localized amyloidosis of the urinary bladder with brief review of the literature.

    Full Text Available Fibrovascular polyps are rare, pedunculated, tumor-like lesions that are usually found in the esophagus; occurrence in the stomach is very rare. To our knowledge, sonographic and CT findings of a fibrovascular polyp in the stomach have never been reported. Here, we report a case of a fibrovascular polyp that was identified in the gastric antrum and prolapsed into the duodenal bulb. Sonography revealed a hyperechoic polypoid mass in the gastric antrum, which prolapsed into the duodenal bulb upon a change in the patient’s position. CT also revealed a pedunculated polypoid mass with an inner fatty component.

    2004-03-01

    Objective: Although it is a rare condition, pigmented villonodular synovitis (PVNS) may involve temporomandibular joint (TMJ). The purpose of this study was to describe magnetic resonance (MR) findings of PVNS of the TMJ. Methods and material: Between April 1992 and August 2000, four patients (two men and two women, 22-58-year-old) who had histologically proven diagnoses of PVNS in their TMJ were found in our institution. Their MR findings were reviewed retrospectively, and were correlated with pathologic findings. Results: In all four patients, MR images invariably showed profound hypointensity on both T1- and T2-weighted sequences. This finding was seen diffusely and homogeneously throughout the lesion, and was considered to be due to paramagnetic effect attributed to heavy hemosiderin pigmentation, which was revealed by histopathological examination. MR images also showed aggressive nature of the lesions with adjacent skull base destruction and intracranial extension in two of them. Conclusion: As is the case in the other anatomic site, PVNS of the TMJ can be confidently diagnosed on MR imaging on the basis of the presence of hemosiderin. MR imaging also plays a pivotal role in surgical planning by precise and detailed localization of the lesion.

    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.

    2010-01-01

    The feline infectious peritonitis virus (FIPV) is a mutated form of the feline enteric coronavirus (FeCV) that can present with a variety of clinical signs. The purpose of this retrospective study was to analyze abdominal ultrasonographic findings associated with cats with confirmed FIPV infection. Sixteen cases were included in the study from a review of medical records at two academic institutions; inclusion was based either on necropsy lesions (n=13) or a combination of histopathological, cytological, and clinicopathological findings highly suggestive of FIPV infection (n=3). The liver was judged to be normal in echogenicity in 11 (69%) cats, diffusely hypoechoic in three cats, focally hyperechoic in one cat, and focally hypoechoic in one cat. Five cats had a hypoechoic subcapsular rim in one (n=3) or both (n=2) kidneys. Free fluid was present in the peritoneal cavity in seven cats and in the retroperitoneal space in one cat. Abdominal lymphadenopathy was noted in nine cats. The spleen was normal in echogenicity in 14 cats and was hypoechoic in two. One cat had bilateral orchitis with loss of normal testicular architecture. Although none of these ultrasonographic findings are specific for FIPV infection, a combination of these findings should increase the index of suspicion for FIPV infection when considered along with appropriate clinical signs.

    Full Text Available OBJECTIVE: We sought to estimate visceral leishmaniasis (VL burden in Bangladesh, India, and Nepal and document care-seeking behaviour for VL to provide baseline information for monitoring the VL elimination program and identify options for improved case finding and management. DESIGN: A cross-sectional study using cluster sampling (clusters being villages of 4 VL endemic districts was used in order to document all current and existing VL cases over the preceding 12 mo. Extended (in-depth interviews were conducted in a subsample of households to explore (a VL-related knowledge, attitudes, and practices of the population; (b use of VL care by patients; and (c delay between onset of symptoms, diagnosis, and start of treatment, as well as treatment interruption. Findings were discussed with national program managers and policy makers to develop improved strategies. RESULTS: Screening for VL was done in 18,933 households (106,425 inhabitants. The estimated annual incidence of VL in the endemic districts was on average 22 times higher than the elimination target of less than one case per 10,000 inhabitants in 2015. This incidence varied widely between study sites, from 9.0 to 29.8 per 10,000 inhabitants. The percentage of newly detected cases through the household screening was high in the districts least covered by health-care services (particularly Rajshahi, Bangladesh, 49%; and to a lesser extent Vaishali in Bihar, India, 32.5%, and much lower in districts with greater availability of VL care (Muzaffarpur, India, 3.8%. On average 267 houses had to be visited, i.e., at least three to four working days per health worker, to identify a new VL (ranging from 1,432 houses in Muzaffarpur, India to only 166 houses in Rajshahi, Bangladesh. Knowledge of the disease and its vectors was good in India and Nepal but poor in Bangladesh (Rajshahi where very little attention has been given to VL over the last decades.

    2014-09-01

    Full Text Available BACKGROUND: Hashimoto thyroiditis is the most common form of thyroiditis. The incidence is found more in the coastal areas for which iodine excess is described as a probable etiology .Ours is a coastal area, where significant number of females is coming to the hospital with diffuse enlargement of thyroid. This prompted us to do the current study. FNAC is a simple, cost effective, diagnostic modality which when used in combination with sonological and serological investigations, helps the clinicians in the correct diagnosis, even in the early stage of the disease. MATERIALS AND METHODS: Retrospective study was done for a period of 18 months from January1rst 2013 to JUNE 31rst 2014. The clinical, sonological and serological aspects of 80 cases of Hashimoto's thyroiditis were studied and compared with the cytomorphological features. RESULTS: The peak incidence of Hashimoto’s thyroiditis was seen in women of 2nd decade. Coexisting colloid goiter was noted in significant number of cases. Subclinical thyroid and euthyroid cases (serologically showed cytomorphological features diagnostic of thyroiditis. Correlation with sonological features were seen in 66 % of cases. Lymphocytic infiltrate in follicular cell clusters, background lymphocytes and plasma cells and hurthle cells were diagnostic of hashimoto's thyroiditis. CONCLUSION: The increased frequency of Hashimoto’s thyroiditis in younger age group, in euthyroid cases and its coexistence with colloid goiter should prompt us to take more detailed and large scale study in Kerala, especially in the coastal areas. FNA should be done as a first line mode of investigation, since it helps in identifying Hashimoto thyroiditis in the initial stages when the serological findings may be normal.

    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

    2016-09-01

    Full Text Available Objective: This case report describes a clinical case of Johne's disease (JD in a Friesian calf aging one and half years. Materials and methods: Physical examination of the calf was carried out, history of the farm as well as samples for laboratory examinations were obtained. The laboratory examinations included hematological examinations by direct wet mount, hematocrit centrifugation technique and Giemsa stain, biochemical evaluation of serum, bacterial culture and isolation from feces and aspirate from the swollen jaw. Results: Clinical history showed that the farm had a history of JD, and routine health screening revealed that one of the calves had clinical signs suggestive of Johne's disease. Physical examination of the calf revealed a lumpy jaw, enlarged bilateral pre-scapular and pre-femoral lymph nodes, while hematological and biochemical findings showed a normocytic normochromic anemia, severe leukocytosis with neutropilic left shift and lymphocytosis with hyperproteinemia characterized by hyperglobulinemia. Fecal bacterial tests showed the presence of acid fast bacilli. Based on the history and laboratory findings, the cow was diagnosed with JD. In order to ensure effective control measures, the calf was culled from the heard. Postmortem examination revealed inflamed pre-scapular and pre-femoral lymph nodes with the presence of paramphistomes in the rumen mucosa. Conclusion: Since JD is a chronic disease that lingers in livestock farms, there is need for early identification and culling of infected animal in order to limit its devastation on the farm.

    Objective To describe CT findings in dogs and cats with temporomandibular joint (TMJ) disorders. Design Retrospective case-series. Animals 41 dogs and 17 cats. Procedures Medical records and CT images of the skull were reviewed for dogs and cats that were examined at a dentistry and oral surgery specialty practice between 2006 and 2011. Results Of 142 dogs and 42 cats evaluated, 41 dogs and 17 cats had CT findings consistent with a TMJ disorder. In dogs, the most common TMJ disorder was osteoarthritis; however, in most cases, there were other TMJ disorders present in addition to osteoarthritis. Osteoarthritis was more frequently identified at the medial aspect rather than the lateral aspect of the TMJ, whereas the frequency of osteoarthritic involvement of the dorsal and ventral compartments did not differ significantly. In cats, fractures were the most common TMJ disorder, followed by osteoarthritis. Clinical signs were observed in all dogs and cats with TMJ fractures, dysplasia, ankylosis, luxation, and tumors; however, only 4 of 15 dogs and 2 of 4 cats with osteoarthritis alone had clinical signs. Conclusions and Clinical Relevance Results indicated that TMJ disorders are frequently present in combination. Osteoarthritis was the most common TMJ disorder in dogs and the second most common TMJ disorder in cats. Computed tomography should be considered as a tool for the diagnosis of TMJ disorders in dogs and cats with suspected orofacial disorders and pain. PMID:23234284

    Authors presented the serial changes of brain MRI findings in two cases of cryptococcal meningitis. The MRI findings of the first patient (53 year old female) consisted of dilated Virchow-Robin spaces, leptomeningeal enhancement, cryptococcals and hydrocephalus. Dilated Virchow-Robin spaces were noted on the first MR obtained 33 days after symptom onset. The size and number of dilated Virchow-Robin space gradually decreased since 119 days after symptom onset (62 days after treatment). Faint leptomeningeal enhancement was found at cerebellar region on the first MRI, which became more distant and intense on the day 119, probably due to improper treatment. The leptomeningeal enhancement decreased on the days 156. Mild hydrocephalus was noted on MRI obtained 70 days after symptom onset, which markedly aggravated on the days 119. It decreased after steroid therapy alone. Enhancing cryptococcomas of variable size were noted at the right temporal lobe and cerebellum on MRI of the day 119, which decreased in size and number on the day 156. On the day 295 MRI showed nearly disappearance of the dilated Virchow-Robin space, but final leptomeningeal enhancement, cerebellar cryptococcomas and hydrocephalus still remained. The MRI findings of the second patient(36 year old female) showed the findings similar to those of the first patient. Initial MRI obtained 18 days after symptom onset showed no abnormal findings. Dilated Virchow-Robin spaces were noted on the day 36 (13 days after treatment onset), which nearly disappeared on the day 109. Enhancing cryptococcomas in both basal ganglia and cerebral cortex and leptomeningeal enhancement were noted on MRI of the day 136. Both cryptococcomas and leptomeningeal enhancement decreased in size and enhancing degree on the day 157. Hydrocephalus was noted on the day 109.

    To investigate how reengagement in valued activities poststroke is influenced by environmental factors. PubMed, CINAHL, and PsycINFO were searched to June 2015 using multiple search terms for stroke, activities, disability, and home and community environments, with the following constraints: English, humans, and adults. Studies were included that contained data on how reengagement in valued activities of community-dwelling stroke survivors was influenced by the environment. Two reviewers independently selected the studies. The search yielded 3726 records; 39 studies were eventually included. Findings were extracted from qualitative, quantitative, and mixed-design studies. Two reviewers independently assessed study quality using the Oxford Critical Appraisal Skills Programme lists and independently extracted results. Thematic analysis was conducted on qualitative data, revealing 9 themes related to the iterative nature of the process of reengagement and the associated environmental factors. During the process of reengagement, environmental factors interact with personal and disease-related factors in a gradual process of shaping or abandoning valued activities. The sociocultural context in this case determines what activities are valued and can be resumed by stroke survivors. Social support; activity opportunities and obligations; familiar and accessible environments; resources and reminders; and a step-by-step return facilitate stroke survivors to explore, adapt, resume, and maintain their activities. Social support is helpful at all stages of the process and particularly is important in case stroke survivors are fearful to explore their activity possibilities. The quantitative data identified largely endorsed these findings. No quantitative data were found in respect to the iterative nature of the process, familiar environments, or accessibility. Reengagement in valued activities is a gradual process. In each stage of the process, several environmental factors

    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 Abstract Introduction In this report, the case of an adult patient with a massive right-sided Bochdalek hernia with multiple displaced abdominal organs, including the liver and gallbladder, is described. This patient presented with acute cholecystitis of the malpositioned gallbladder. During surgery, nodular regenerative hyperplasia of the liver was also found. To the best of this author's knowledge, these two entities have never been reported in association with this rare condition. Case presentation A 54-year-old Caucasian man presented with nausea and epigastric pain. He had a known history of right-sided Bochdalek hernia which was being managed expectantly. A computerized tomogram revealed the massive hernia with displaced stomach, liver, intestine and omentum into his right thorax. It was believed that our patient had bowel incarceration and he was therefore taken to surgery, where acute cholecystitis and a macronodular liver was identified. A thoracoabdominal approach was used to remove his gallbladder, reduce the herniated viscera and reconstruct his diaphragm. A liver biopsy identified nodular regenerative hyperplasia of the ectopic liver. There were no postoperative complications and at 12 month follow-up, our patient continues to do well. Conclusion This case report describes two unusual findings associated with a congenital Bochdalek diaphragmatic hernia that have never been reported. In addition, unique caveats to the surgical management of this complex rare condition are discussed.

    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.

    We here report a 39-year-old woman of short stature with sensorineural deafness, who suddenly developed status epilepticus. T2-weighed image of brain magnetic resonance imaging (MRI) revealed a high signal lesion in the left temporal area, the distribution of which was not compatible with any particular arterial supply. Lactate and pyruvate were elevated in the serum and cerebrospinal fluid. As the mitochondrial gene analysis revealed the m.3243A>G mutation, diagnosis of mitochondrial myopathy, encephalopathy, lactic acidosis, and stroke-like episode (MELAS) was made. In the histochemical study of a biopsied muscle, the intramuscular blood vessels reacted strongly with SDH (SSV), but the SSV was negative for cytochrome c oxidase (COX), the findings characteristic of myoclonic epilepsy with ragged-red fibers (MERRF). This is the first case of MELAS in which the muscle histochemistry showed positive SSV unassociated with increased COX.

    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.

    Full Text Available Pretreatment radiographs, especially panoramic and lateral cephalometric are routinely used as an aid in orthodontic diagnosis and treatment planning. Sometimes abnormalities may be detected as incidental findings in such radiographs that require medical or odontological management. Simple bone cyst is an uncommon lesion mostly occurring in young individuals; it is often asymptomatic and accidently discovered during routine radiological examination. Mostly the pathology presents as a unilocular radiolucency in the mandible between canine and third molar. A definite diagnosis is invariably achieved during surgery as it presents as an empty cavity without lining. We present a case of a simple bone cyst of the body of mandible identified during routine pretreatment orthodontic radiograph.

    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.

    Transport networks are studied most of the time from a graph theory perspective, mostly studied in a static way, in order to emphasize their characteristics like: topology, morphology, costs, traffic flows etc. There are many methods used to describe these characteristics at local and global level. Usually when analysing the transport network models, the aim is to achieve minimum capacity transit or minimum cost of operating or investment. Throughout this paper we will get an insight into the many models of the transport network that were presented over the years and we will try to make a short analysis regarding the most important ones. We will make a case study on finding the optimal route by using one of the models presented within this paper.

    Hundreds of syndromes may be associated with hearing impairment. Within recent years, there has been heightened research and clinical interest in hearing and syndromes, probably due to both advances in molecular genetics and improved techniques for auditory assessment of infants and young children. An example of the current appreciation for the possible relation between auditory dysfunction and syndromes or patterns of malformations is the inclusion of syndromes as a risk factor for hearing impairment by the 1990 Joint Committee on Infant Hearing. In this paper, we review syndromes and patterns of malformation that are frequently or occasionally associated with hearing impairment. In addition, we illustrate, in case studies, auditory findings that may be associated with three of these syndromes and patterns of malformation: Carpenter syndrome, ichthyosiform dermatosis, and Townes syndrome. We conclude with a discussion of strategies for audiologic assessment and management of infants and children with syndromes and patterns of malformations.

    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)

    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.

    We describe a case of immunoglobulin G4 (IgG4)-related sclerosing esophagitis occurring in a 63-year-old man with progressive dysphagia and 10-kg weight loss over 9 months. An esophagoscopy revealed significant stricture with diffuse mucosal friability and ulceration at mid esophagus level. Barium esophagogram showed diffuse stenosis at the mid and lower esophagus levels with ulcerations and irregularity of the mucosa. Multidetector computed tomography revealed diffuse edematous and circumferential thickening of the submucosa and muscle layer of this esophageal segment. Fluorine 18 fluorodeoxyglucose positron emission tomography (FDG PET) revealed diffuse mild FDG uptake in mid to lower esophagus. Although benign inflammatory lesion was suspected based on the imaging findings, the patient underwent surgery for worsening esophageal stricture and the esophageal lesion was pathologically confirmed as IgG4-related sclerosing esophagitis. Radiologic benignancy and high clinical suspicion for IgG4-related sclerosing disease may help making a proper decision and avoiding unnecessary operation.

    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.

    Hemorrhagic cholecystitis(HC) is a rare complication of gallbladder(GB) disease characterized by mucosal and intraluminal hemorrhage of the GB. We report ultrasonographic(US) and computed tomographic(CT) findings of two cases of HC. Hemorrhagic fluid filled in the inflamed GB lumen was initially seen as homogeneous hyperdense and hyperattenuated lesion on both US and CT, respectively. As resolution of the hematoma and gangrenous change of the GB wall progress, US showed inhomogeneous mixed echogenic lesion in the GB having partially indistinct border, mimicking an invasive mass. At this stage, CT still showed homogeneous hyperdense hematoma and a small amount of fluid in the GB, without evidence of contrast enhancement.

    Spinal angiomyolipoma (AML) is a rare disease. It is often reviewed with spinal angiolipoma. Both are composed of vascular and mature adipose elements. However, only AML contains broader array of mesenchymal component. They are accounting for 0.14% to 1.2% of spinal tumors. They appear as fat containing hypervascular tumor located at epidural space of thoracic spine. Spinal AML is more frequently infiltrative and often occurs more ventrally than angiolipoma. Previous studies have employed conventional radiograph, myelogram, and CT scan for spinal AML studies. Recently, MRI has been used for spinal AML in a few studies. Here, we describe a case of typical thoracic spinal AML with a review of its MRI findings and other differential diagnosis for epidural spinal mass with similar characteristics.

    We report two cases of giant cell tumor arising from the rib and their F-18 FDG PET/CT findings. The two patients complained of chest wall pain, and large lobulated soft tissue masses with intense FDG uptake were seen on F-18 FDG PET/CT. A malignant tumor such as osteosarcoma or chondrosarcoma was suspected due to the large size of the mass, bony destruction, and intense FDG uptake. En bloc resection was performed and final pathologic results revealed giant cell tumor of the rib. Giant cell tumor of the rib is very rare, and larger lesions with high FDG uptake can be misdiagnosed as an intrathoracic malignancy arising from the rib, pleura, or chest wall.

    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.

    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.

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

    2016-06-01

    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.

    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.

    2017-02-06

    Published reports of rib fractures in adult cattle are limited to the occurrence of chronic rib swellings caused by calluses, which are unremarkable from a clinical standpoint, whereas studies identifying clinical signs of rib fractures were not found in a literature search. This report describes the clinical and postmortem findings in four cows with rib fractures. The 13th rib was fractured in three cows and the 11th rib in the remaining cow; three fractures were on the right and one on the left side. Clinical and postmortem findings varied considerably, and percussion of the rib cage elicited a pain response in only one cow. One cow had generalised peritonitis because of perforation of the rumen by the fractured rib. One cow was recumbent because of pain and became a downer cow, and two other cows had bronchopneumonia, which was a sequel to osteomyelitis of the fracture site in one. In the absence of a history of trauma, the diagnosis of rib fracture based on clinical signs alone is difficult. Although rib fractures undoubtedly are very painful, the four cases described in this report suggest that they are difficult to diagnose in cattle because associated clinical signs are nonspecific.

    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.

    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.

    The aim of this study is to report ophthalmic findings of acute mercury poisoning in 48 adults referred to emergency department. Full ophthalmologic examination including the best corrected visual acuity, external eye examination, reaction to light, a slit-lamp examination, funduscopy, intraocular pressure measurements, and visual field (VF) and color vision (CV) tests were performed at the presentation and repeated after 6 months. The parametric values of VF test, the mean deviation (MD), and pattern standard deviation (PSD) were recorded in order to compare patients and the 30 healthy controls. The mean parameter of color confusion index in patients was found to be statistically different than controls (p < 0.01). The MD and PSD in patients were different from controls statistically significant (p < 0.01 and p < 0.01, respectively). There was no correlation between the ocular findings and the urine and blood mercury levels. Methyl mercury, held in the school laboratory for experimental purpose, may be a source of poisoning. In this case series, we showed that acute exposure to mercury had hazardous effect on the visual system, especially CV and VF. We propose that emphasizing the public education on the potential hazards of mercury is crucial for preventive community health.

    Primary malignant fibrous histiocytoma (MFH) of the pancreas is rare and a distinct clinical entity. We report a case of recurrence of pancreatic MFH with computed tomography (CT) and magnetic resonance imaging (MRI)findings. A 67-year-old man presented with a history of decreased body weight over the past 6 mo. Abdominal CT revealed a large, multilocular cystic mass in the head of the pancreas with obvious atrophy in the body and tail of the pancreas. After 6 mo postoperatively, MRI demonstrated a recurrent large mass in the primary area of the head of the pancreas. The lesion was heterogeneous, hypointense to the liver on Tl-weighted imaging, and heterogeneously hyperintense to the liver with a hypointense area in the central part of the tumor on fat-saturated T2-weighted imaging. Contrastenhanced Tl-weighted imaging demonstrated a large multilocular cystic mass with a cystic wall, fibrous septa and enhancement of solid components. To the best of our knowledge, this is the first report on recurrence of primary MFH of the pancreas, and the first with MRI findings.

    Despite a few case reports over the last 60 years, little progress has been made in defining the phenotype, genotype and pathophysiological mechanisms involved in pigmentary orthochromatic leukodystrophy (POLD). Furthermore, there is currently no data available regarding MRI in patients in the relatively early stages of POLD. Here, we present a 37 year old male patient with brain biopsy-proven POLD who had brain MRIs three times during the first year of his clinical course and proton MR spectroscopy (MRS) throughout his diagnostic evaluation. This patient with POLD was clinically characterized by seizures, rapidly progressive frontally predominant dementia and gait disturbance. The brain MRIs taken serially over the first year revealed progressive development of frontal-predominant white matter changes in the periventricular areas during the earlier periods, which later spread into the deep white matter. His MRS was helpful in the diagnostic approach because the results enabled demyelinating changes to be distinguished from other disease processes such as ischemia, gliosis or tumors. The MRS findings also reflected the disease dynamics because metabolic derangement was observed, even in the white matter that appeared normal. The findings presented here provide insight into the dynamics of POLD. Copyright (c) 2010 Elsevier B.V. All rights reserved.

    Cutaneous disease is the third most frequent manifestation of mucormycosis. The clinical manifestations of and subsequent mortality due to cutaneous mucormycosis are dependent on the mode of acquisition and the host immune status. Here, we describe the epidemiology, clinical presentation, microbiology, and outcomes of 16 cutaneous mucormycosis infections managed in an Australian tertiary hospital over a 15-year period. The proportion with localized (56%), deep (38%), and disseminated (6%) cutaneous disease as well as the overall mortality (25%) were consistent with findings reported in the published literature. Two novel forms of hospital-acquired infection were reported following a sacral pressure sore and insertion of a foreign body during a bone graft procedure. The majority of patients were immunocompetent (75%) and/or suffered trauma (56%) with associated environmental contamination. A novel finding was that motor vehicle accidents (MVAs) accounted for 78% of all trauma-related cases, suggesting MVAs should receive greater recognition as a potential precipitant of cutaneous mucormycosis. Aggressive decontamination and debridement of devitalized tissue following trauma is therefore likely to play an important role in the prevention of this rare but potentially devastating infection. © The Author 2014.

    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.

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.

    To report the results of a case-finding study conducted during a feasibility trial of a supported self-management intervention for adults with mild to moderate intellectual disability and Type 2 diabetes mellitus, and to characterize the study sample in terms of diabetes control, health, and access to diabetes management services and support. We conducted a cross-sectional case-finding study in the UK (March 2013 to June 2015), which recruited participants mainly through primary care settings. Data were obtained from medical records and during home visits. Of the 325 referrals, 147 eligible individuals participated. The participants' mean (sd) HbA1c concentration was 55 (15) mmol/mol [7.1 (1.4)%] and the mean (sd) BMI was 32.9 (7.9) kg/m(2) , with 20% of participants having a BMI >40 kg/m(2) . Self-reported frequency of physical activity was low and 79% of participants reported comorbidity, for example, cardiovascular disease, in addition to Type 2 diabetes. The majority of participants (88%) had a formal or informal supporter involved in their diabetes care, but level and consistency of support varied greatly. Post hoc exploratory analyses showed a significant association between BMI and self-reported mood, satisfaction with diet and weight. We found high obesity and low physical activity levels in people with intellectual disability and Type 2 diabetes. Glycaemic control was no worse than in the general Type 2 diabetes population. Increased risk of morbidity in this population is less likely to be attributable to poor glycaemic control and is probably related, at least in part, to greater prevalence of obesity and inactivity. More research, focused on weight management and increasing activity in this population, is warranted. This article is protected by copyright. All rights reserved.

    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.

  12. Report of a New Case With Pentasomy X and Novel Clinical Findings

    Full Text Available Pentasomy X is an extremely rare sex chromosome abnormality, a condition that only affects females, in which three more X chromosomes are added to the normally present two chromosomes in females. We investigated the novel clinical findings in a 1-year-old female baby with pentasomy X, and determined the parental origins of the X chromosomes. Our case had thenar atrophy, postnatal growth deficiency, developmental delay, mongoloid slant, microcephaly, ear anomalies, micrognathia and congenital heart disease. A conventional cytogenetic technique was applied for the diagnosis of the polysomy X, and quantitative fluorescent polymerase chain reaction (QF-PCR using 11 inherited short tandem repeat (STR alleles specific to the chromosome X for the determination of parental origin of X chromosomes. A cytogenetic evaluation revealed that the karyotype of the infant was 49,XXXXX. Comparison of the infant’s features with previously reported cases indicated a clinically recognizable specific pattern of malformations referred to as the pentasomy X syndrome. However, to the best of our know-ledge, this is the first report of thenar atrophy in a patient with 49,XXXXX. The molecular analysis suggested that four X chromosomes of the infant originated from the mother as a result of the non disjunction events in meiosis I and meiosis II. We here state that the clinical manifestations seen in our case were consistent with those described previously in patients with pentasomy X. The degree of early hypotonia constitutes an important early prognostic feature in this syndrome. The pathogenesis of pentasomy X is not clear at present, but it is thought to be caused by successive maternal non disjunctions.

    2014-01-01

    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. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    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.

    Transient cortical blindness (TCB) is a rare but striking complication following contrast agent injection. TCB might be secondary to a direct toxicity of the contrast agent, leading to an osmotic disruption of the blood-brain barrier (BBB), with a preferential involvement of the posterior circulation and occipital cortex. We report a series of three patients with contrast medium-associated TCB (intra-arterial injection of non-ionic contrast agent during diagnostic cerebral angiography for two of them and coronary angioplasty for the other one). In two patients, the magnetic resonance imaging (MRI) was unremarkable; in the other patient, typical MRI findings were observed, with FLAIR hyperintensities in the right occipital cortex and decreased apparent diffusions coefficient (ADC). Interestingly, this patient also presented posterior rhythmic epileptiform activities on electroencephalogram during the first 36 h. Visual evoked potentials (VEPs) showed normal retinal potential, but a massive destructuration of the later potentials of the cortical origin. To our knowledge, this is the first time that VEPs acquired during TCB are reported. We discuss these findings with respect to the pathophysiology of TCB.

    Hair analysis for drugs has been developing and is considered a significant tool for distinguishing between recent and long-term drug abuse in forensic and clinical toxicology. Chronic consumption of drugs can gradually induce certain harmful effects on the human organism and can exacerbate some pre-existing diseases. Analysis for drugs in blood or urine in isolation does not provide sufficient information about the history of drug-use by a person and their results cannot be correlated directly with the toxic effects displayed. The chronic abuse of methamphetamine is known to be associated with cardiovascular diseases. During or after autopsy certain types of morphologic alterations are found in the hearts of stimulant addicts. The rapid increase in blood pressure after an intravenous methamphetamine dose can be risky for addicts with arteriosclerosis. However, the anamnestic data about a deceased person may not always be available to explain the pathological findings and to classify the cause of death correctly. The aim of this study was to demonstrate the value of hair analysis for drugs in the context of explaining pathological cardiovascular alterations observed during the autopsy in a case where methamphetamine consumption was involved. In this case, only methamphetamine and metabolites were detected with traces of ephedrine. Ephedrine is the precursor chemical in the illicit synthesis of methamphetamine (known in the Czech Republic as "Pervitin"). The femoral blood level of methamphetamine was 1500 ng/ml. It was documented by a witness that the 31-year-old man died within 1h after an intravenous injection of the drug. The cause of death was established as cerebral edema due to cerebellar bleeding shortly after an intravenous dose of methamphetamine. Findings of methamphetamine in the first three 2-cm hair segments (numbered from the roots) were nearly equal (132+/-9 ng/mg). In the fourth 2-cm segment, it was approximately one-half of previous values. In the

    Deaths at music festivals are not infrequently reported in the media; however, the true mortality burden is difficult to determine as the deaths are not yet systematically documented in the academic literature. This was a literature search for case examples using academic and gray literature sources, employing both retrospective and prospective searches of media sources from 1999-2014. The gray literature documents a total of 722 deaths, including traumatic (594/722; 82%) and non-traumatic (128/722; 18%) causes. Fatalities were caused by trampling (n=479), motor-vehicle-related (n=39), structural collapses (n=28), acts of terror (n=26), drowning (n=8), assaults (n=6), falls (n=5), hanging (n=2), and thermal injury (n=2). Non-traumatic deaths included overdoses (n=96/722; 13%), environmental causes (n=8/722; 1%), natural causes (n=10/722; 1%), and unknown/not reported (n=14/722; 2%). The majority of non-trauma-related deaths were related to overdose (75%). The academic literature documents trauma-related deaths (n=368) and overdose-related deaths (n=12). One hundred percent of the trauma-related deaths reported in the academic literature also were reported in the gray literature (n=368). Mortality rates cannot be reported as the total attendance at events is not known. The methodology presented in this manuscript confirms that deaths occur not uncommonly at music festivals, and it represents a starting point in the documentation and surveillance of mortality.

It can occur in the context of both psychiatric and organic illness, and seems to be related to lesions of the bifrontal and right limbic and temporal regions. Indeed, magnetic resonance imaging has revealed brain lesions in patients suffering from Capgras syndrome. This case study reports the findings of a thorough diagnostic evaluation in a woman suffering from Capgras syndrome and presenting with the following clinical peculiarities: obsessive modality of presentation of the delusional ideation, intrusiveness of such ideation (that even disturbed her sleep, as well as a sense of alienation and utter disgust towards the double. These characteristics bring to mind the typical aspects of obsessive-compulsive disorder. Neuroanatomic investigation, through magnetic resonance imaging, performed on this patient showed alteration of the bilateral semioval centers, which are brain regions associated with the emotion of disgust and often show alterations in subjects suffering from obsessive-compulsive disorder. Hence, neuroimaging allows researchers to put forward the hypothesis of a common neuroanatomic basis for Capgras syndrome and obsessive-compulsive disorder, at least for cases in which the delusional ideation is associated with deep feelings of disgust and presents with a certain pervasiveness.Keywords: Capgras syndrome, magnetic resonance imaging, electroencephalography, obsessive-compulsive disorder, semioval centers

    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.

    A case of atlanto-axial rotatory fixation (AARF) was presented in a 19-year-old female who developed sudden onset of neck pain and limitation of neck movement after direct carotid angiography for seizure disorder. Neurological examination was negative except for cock-robin posture and mild hypesthesia and hypalgesia in left C/sub 2/ distribution. Plain films of the cervical spine disclosed abnormal alignment of C/sub 1/-C/sub 2/ and possible rotational dislocation. Bilateral selective vertebral angiography showed marked anterior and posterior displacement of left and right vertebral artery, respectively, at the level of C/sub 1/. On CT metrizamide myelography, there was clockwise rotation of C/sub 1/ on C/sub 2/ with locked facet on the left but no evidence of cord compression was found. With diagnosis of AARF, manual reduction under general anesthesia and with fluoroscopic control was first attempted without success. Therefore, the patient underwent open reduction by using high speed air-drill and posterior fusion of C/sub 1/ to C/sub 3/ with acryl and wire. Postoperative course was uneventful and the patient went back to work as a computer operator in three months. The etiology of AARF was described by many authors, but in our case, congenital hypogenesis of transverse and alar ligaments plus minor trauma was most suggested. For neurological manifestations of AARF, occipital neuralgia, headache, neck pain, limitation of neck movement and cock-robin posture were reported, but the cock-robin posture was most characteristic and was an important symptom for the early diagnosis. In neuroradiological findings of AARF, plain CT and CT metrizamide myelography are very useful. Because they clearly demonstrate the degree of rotation and interlocking of atlanto-axial joints, and the presence of cord compression.

    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.

    Full Text Available Objectives The work serves as a preliminary evaluation of the utility of the full-body radiography in examining cases of SUDI. Setting This paper reviews findings from full-body digital radiography in cases of sudden unexpected death in infants (SUDI in 2008 at the Salt River Forensic Pathology Laboratory in Cape Town. Subjects Cases of SUDI referred to the mortuary and undergoing full-body digital radiography were reviewed (192 cases. Design Imaging reports were cross-referenced with death registry data. Manner of death, cause of death, whether an autopsy had taken place, and radiological findings, were recorded and analysed. Results The absence of bony fractures was recorded as an imaging finding in 40% of cases. The most common type of imaging pathology was lung disease. In cases where autopsies were performed and pathology was found on imaging, the findings of the two methods of examination were consistent. Conclusions Imaging may have served to assist CoD determination based on case history, and therefore full-body radiography may improve the workflow in busy forensic pathology laboratories. More detailed and consistent recording of imaging findings is required before stronger conclusions may be drawn regarding the utility of full body digital imaging of paediatric cases in forensic pathology laboratories.

    On lifting a heavy case, a 51-year-old male experienced a sudden onset of headache with giddiness and clouded vision. A week later, vertigo and right hand numbness were added to his symptoms. The next day anisocoria (right > left) and dilation of the left retinal veins were noted. Cranial computed tomography (CT) scan appeared normal and there were no other remarkable neurological findings. The patient was treated conservatively for cerebral infarction, however, the headache worsened and diplopia occurred. Neurological examination on admission revealed nothing unusual except for left Horner's syndrome. Physical examination showed a palpable sausage-like painless tumor on the left side of the neck. Angiography showed a narrowing of the internal carotid artery in the cervical region with a small dissecting aneurysm at the C3 level. Cervical CT scan at the upper C3 level showed a low density lunar defect in the high density section of the enlarged left internal carotid artery. The patient was operated on by superficial temporal artery-middle cerebral artery anastomosis to increase the intracranial blood flow. Postoperatively the symptoms were quickly relieved. Angiography 1 month later showed less narrowing of the carotid artery, though the dissecting aneurysm still remained. Postoperative cervical CT scan showed the left internal carotid artery to be of normal size. The patient returned to his work in normal condition 2 months later. It is emphasized that cervical CT scan may be useful in the diagnosis of this unusual type of cervical dissecting aneurysm.

    Primary pulmonary neoplasms of the Ewing family of tumors (EFT) are extremely rare and usually occur in adolescents or young adults. Only about 40 cases of pulmonary EFT have been reported in English literature, and no cytological studies have been documented. In this report, we describe the cytopathological findings of a primary pulmonary EFT in an elderly patient. A 70-year-old man sought care because of a progressing cough and dyspnea. Chest computed tomography revealed a circumscribed mass of 6 cm in the left upper lobe. Fine needle aspiration cytology and core needle biopsy revealed uniform round cell proliferation. The predominant population consisted of cells with thickened nuclear membranes, finely dispersed chromatin, single distinct nucleoli, and indistinct cytoplasm. The other population consisted of smaller cells with darker chromatin. The cytoplasm stained positive for periodic acid-Schiff stain and was digested by diastase. Immunohistochemistry showed positivity for MIC2 (CD99), and focal positivity for neuron specific enolase, synaptophysin, and chromogranin A. Fluorescence in situ hybridization (FISH) revealed EWSR1 translocation. Although rare, pulmonary EFT cannot be disregarded, regardless of age. When two populations of uniform, round cells are observed, immunohistochemistry with MIC2 (CD99) and cytogenetic analysis by reverse transcription polymerase chain reaction or FISH should be considered. Cytological diagnosis may play an important role in the early diagnosis and treatment of pulmonary EFT. © 2016 The Authors.

    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

    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.

    A 27-year-old woman presented with headache and occasional numbness over her right face. Computed tomography revealed a hypodense mass in the middle cranial fossa and another adjacent hyperdense mass in the posterior fossa with erosion of the right petrous apex. Magnetic resonance imaging revealed the lesion in the middle cranial fossa as iso- to hypointense on T(1)-weighted and hyperintense on T(2)-weighted imaging, with peripheral enhancement after gadolinium administration, and the adjacent lesion in the posterior fossa as hyperintense on T(1)-weighted and hypointense on T(2)-weighted imaging. During surgery, these lesions mimicking two adjacent distinct tumors were revealed to connect through Meckel's cave. The hypodense lesion in the middle cranial fossa consisted of pearly-like solid contents, and the hyperdense lesion in the posterior cranial fossa consisted of viscid dark-green materials. The tumors were gross totally resected with endoscopic assistance. Histological examination confirmed that the tumor was an epidermoid cyst. The present case cyst indicates that although the diffusion-weighted imaging sequence is useful for detection of intracranial epidermoid cysts, epidermoid cysts including viscous materials with unusual radiological findings could complicate the preoperative diagnosis.

    This article explores in a primary care setting how clinical learning occurs across a range of professional groups and levels of learner experience, both undergraduate and postgraduate. To explore how clinical learning occurs in a primary care workplace from a socio-cultural perspective. A single case study approach using interview data from 33 participants and strengthened through direct and indirect observations and documentary evidence. Clinical learning occurs through engagement and opportunity. Engagement in learning appeared to be developed through four elements: recognition, respect, relevance and emotion. Opportunity includes the availability of patient encounters (made meaningful through the immediacy of hearing patient narratives de novo and the authenticity arising from the social context of illness) and the ability to learn with peers and professional colleagues. These findings support and develop existing literature on learning in other clinical settings. They are consistent with socio-cultural theories of learning, but develop this literature within the context of clinical education. Engagement and learning occurred in transient learners in the absence of prolonged participation, belonging or a clear trajectory of learning. The study offers evidence from multiple learner perspectives as to how the learning environment might be enhanced in all educational settings.

    Full Text Available We report two cases of myotonic dystrophy in one family; both diagnosed from genetic analysis following ophthalmic indications, but before the manifestation of systemic symptoms. A 39-year-old female visited our clinic for routine examination. Mild ptosis, sluggish pupillary response, and bilateral snowflake cataracts were found. Fundus examination revealed an increased cup-to-disc ratio (CDR in both eyes and a defect in the retinal nerve fiber layer in the right eye. Intraocular pressure was low, but within the normal range in both eyes. Because cataracts are characteristic of myotonic dystrophy, we suggested that her 14-year-old daughter, who did not have any systemic complaints, undergo ophthalmic examination. She also had mild ptosis and snowflake cataracts. Both patients underwent genetic evaluation and were diagnosed with myotonic dystrophy caused by unstable expansion of cytosine-thymine-guanine trinucleotide repeats in the dystrophia myotonica-protein kinase gene. Ophthalmologists can diagnose myotonic dystrophy based on clinical and genetic findings, before the manifestation of systemic abnormalities.

    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.

    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

    Patients with hypohidrotic ectodermal dysplasia (HED) are characterized by the clinical manifestations of hypodontia, hypohidrosis, hypotrichosis and a highly characteristic facial physiognomy. This disorder is inherited as an X-linked trait. This report presents three cases with HED in which the clinical evaluation (intraoral and radiological), genetic findings and SEM examination of hair. Boys 6 to 14 year old and a 11 year old girl were referred to the Marmara University, Faculty of Dentistry, complaining of oligodontia in the maxillary and mandibular arches and delay in eruption of other teeth. Peg-shaped teeth have been observed. The dermatoglyphs of the patients were striking. SEM examination of hair demonstrated a distinctly abnormal longitudinal grooving along the entire length of each hair and a desquamation of the surface cuticles. The treatment was planned in a multidisciplinary odontological group involving pediatric dentistry, orthodontics, prosthodontics and oral surgery and maxillofacial radiology of future dental habilitation. A specially designed overdenture, a removable prosthesis and osseointegrated implants were constructed. Periodic recall visits were advised, to monitor the dentures and implants during periods of growth and development, and eruption of the permanent teeth.

    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.

Fundus photography and fluorescein angiography were performed on a 6-year-old male with Rubinstein-Taybi syndrome due to CREB binding protein gene mutation. Fundus photography showed glaucomatous cupping and diffusely attenuated retinal vasculature. Choroidal vasculature was prominent due to diffuse retinal atrophy with scattered focal retinal pigment epithelial changes. Fluorescein angiography showed retinal vascular attenuation, prolonged arteriovenous transit time with delayed venous filling, late small vessel leakage, and 360 degrees of peripheral avascularity. Peripheral retinal avascularity and retinal vascular inflammation evidenced by late small vessel leakage can be demonstrated by fluorescein angiography in the retinal dystrophy of Rubinstein-Taybi syndrome.Keywords: Rubinstein-Taybi syndrome, CREB binding protein, gene mutation

    A case of encapsulated subdural empyema was reported. This 1.5-year-old boy was admitted with the increasing confusion and convulsion. Eight months prior to admission, he had craniotomy for traumatic acute epidural hematoma on the left side. Following a coagulation of the middle meningeal artery which was the bleeding source, the dura was opened but no cortical damage was noted at that time. The computed tomographic (CT) scan on admission revealed a large subdural collection with a thin enhancing rim on the left side. Emergency craniotomy revealed a collection of subdural pus, which was irrigated and a catheter was put for continuous drainage. Postoperatively, the patient did well, however, following removal of the catheter, three weeks after the first operation, the subdural empyema was reexpanded with a very thick enhancing rim on CT scan. Ultrasonography also clearly demonstrated the formation of the thick membranes. The large craniotomy was performed and empyema with the outer and inner memberanes of 8mm thick was totally excised. Post-operative CT scan did not show any enhancing rim, indicating that enchancement was caused by newly formed vessels within the membranes per se. This findings are totally different from those observed in the brain abscess in which ring enhancement on CT continues months to years following so-called extracapsular excision of abscess. In the brain abscess, surrounding glial tissue with plenty neovascularization is left intact, even after the operation. (author).

    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.

    Children with amelogenesis imperfecta (AI) experience many oral difficulties including sensitivity and aesthetics. The methods of treating AI children are limited and therefore a program of care was evaluated in order to assess the clinical efficacy of providing preventive and restorative treatments. A non-randomised convenience sample of 12 patients with AI was evaluated. A comprehensive patient history was recorded, followed by a clinical and radiographic assessment of oral health. In 8/12 patients a hypoplastic form of AI was diagnosed, in 2/12 cases hypomaturation and in 2/12 cases hypocalcified form were noted. Chief complaints were mainly related to unsatisfactory aesthetics and dental sensitivity. In 8 patients there was active dental caries. Most of the patients had gingivitis and showed fair oral hygiene. The presence of non-enamel dental anomalies was recorded in 9 patients. All patients received meticulous preventive care. Initial treatment depended on AI type and oral health of the patient. During the transition period, both conventional and resin modified glassionomer cements, as well as composite resin materials, were used to restore posterior teeth. Direct composite resin restorations were used to improve the appearance of anterior teeth. In 4 patients a long-lasting interdisciplinary approach including orthodontics, metal-ceramic crowns and fixed partial dentures, and direct composite restorations was required. Follow-up periods varied between 2-11 years. All children have been regularly recalled at 3 monthly intervals. Caries prevalence has remained low during the follow-up postoperative period and patients have reported satisfaction with the treatment they have received. AI is associated with multiple non-enamel anomalies and requires a complex treatment. Treatment planning is related to the age of the patient, the type and severity of the disorder, and the oral health of the patient. Early diagnosis, preventive care and timely treatment are of

    An outbreak of dengue fever in Madeira island was reported in 2012. Clinical and laboratory findings of the first two laboratory-confirmed autochthonous cases are reported. Both cases had fever (≥38 °C) and petechial rash. Symptoms also included myalgia, asthenia, nausea, vomiting, anorexia, diffuse abdominal pain, and diarrhoea. The two cases were confirmed by serology and one tested positive for a dengue viral sequence. Dengue virus serotype DEN-1 was identified with probable Central or South American origin.

    'Finding the missing millions' with chronic obstructive pulmonary disease became part of the Department of Health strategy for England in 2010. Targeted case-finding within primary care is one potential pro-active strategy, but currently little is known about the views of healthcare professionals on this approach. In this study, 36 healthcare professionals (12 GPs, 14 nurses, and 10 practice managers) from 34 UK practices participated in semi-structured telephone interviews about targeted case-finding. Interviews followed an interview guide, were audio-recorded, transcribed verbatim, coded and analysed using 'Framework Approach'. Most of those interviewed practiced opportunistic case-finding. The main perceived barriers to wider case-finding programmes were the resource implications associated with running such programmes and identifying more chronic obstructive pulmonary disease patients. Financial incentives, support from specialist clinicians, and comprehensive guidance were viewed as facilitators. While targeted case-finding is conceptually accepted by primary care staff, scepticism surrounding (1) the value of identifying those with mild disease and (2) the availability of effective targeted case-finding methods, may lead some to favour an opportunistic approach. Key concerns were a lack of unequivocal evidence for the relative benefits vs. disadvantages of diagnosing patients earlier, and resource constraints in an already over-burdened system. Barriers to practical implementation of case-finding studies may be addressed with financial, human and educational resources, such as additional staff to undertake searches and perform spirometry tests, and practical and educational support from specialist teams. SUPPORT NEEDED TO IDENTIFY THOSE UNDIAGNOSED: Additional staff and resources would facilitate targeted searches for patients showing symptoms of early-stage chronic lung disease.

    The purpose of this study was to evaluate the burden of pulmonary tuberculosis in 10 prisons mostly located in the Marmara Region of Turkey, and to compare them with the country incidence. All the inmates in ten prisons mostly located in the four cities in the Marmara Region of Turkey were enrolled in this study. Tuberculosis screening was done between January 2006-January 2007. Radiological screening for tuberculosis was performed by the mobile X-ray system and it was followed by bacteriological analysis of sputum for tuberculosis suspects. Four physicians evaluated the X-rays independently. Four thousand six hundred and fifteen prisoners were detected by radiological screening. Three hundred and one (7%) of them were female and 4314 (93%) were male, age range was between 14-72 years. Age ranges of female and male prisoners were 16-59 and 14-72 respectively. 398/4615 (8.6%) were young adults inmates with an age range of 14-18. Radiological abnormalities consistent with tuberculosis were found in 130 chest X-rays and followed by sputum bacteriology. Smear and culture positive pulmonary tuberculosis diagnosed in five out of 130, were all male with mean age 33 ± 10 years. Tuberculosis prevalence in the prisons was found to be 108/100.000 which was four times higher than the overall incidence of tuberculosis in Turkey in the year which the present study was conducted. Prisoners are one of the most important risk groups with high burden of tuberculosis in Turkey. This result highlights the need for adequate case- finding strategies in prisons.

    In the clinical development of radiopharmaceuticals the dose finding plays an important role. The contribution is focused on the evaluation and planning of dose finding studies with active control. It is of primary interest to find the lowest dose that yields the same efficacy as the active control. Besides the target dose confidence intervals are of importance to describe the quality of the target dose estimation. The calculation of case numbers and the determination of the dose steps to be studied are challenging under practical conditions. The contribution covers the demonstration of the statistical model the parameter estimation and the asymptotic properties based on maximum likelihood theory, the spline-based evaluation of nonlinear dose finding studies with active control and the planning of design and number of cases.

    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.)

    Recently, it has been recognized that pathologically proven progressive supranuclear palsy (PSP) cases are classified into various clinical subtypes with non-uniform symptoms and imaging findings. This article reviews essential imaging findings, general information, and advanced magnetic resonance imaging (MRI) techniques for PSP and presents these MRI findings of pathologically proven typical and atypical PSP cases for educational purposes. With the review of literatures, notably including atypical pathologically proven PSP cases, MRI and clinical information of 15 pathologically proven typical and atypical PSP cases were retrospectively evaluated. In addition to typical symptoms, PSP patients can exhibit atypical symptoms including levodopa-responsive parkinsonism, pure akinesia, non-fluent aphasia, corticobasal syndrome, and predominant cerebellar ataxia. As well as clinical symptoms, the degree of midbrain atrophy, a well-known imaging hallmark, is not consistent in atypical PSP cases. This fact has important implications for the limitation of midbrain atrophy as a diagnostic imaging biomarker of PSP pathology. Additional evaluation of other imaging findings including various regional atrophies of the globus pallidus, frontal lobe, cerebral peduncle, and superior cerebellar peduncle is essential for the diagnosis of atypical PSP cases. It is necessary for radiologists to recognize the wide clinical and radiological spectra of typical and atypical PSP cases. (orig.)

    Case management has been a widely accepted approach to practice in various care settings. This study aimed to explore how community aged care case managers allocated their time to case management functions, how frequently they performed specific case management activities, and what factors influenced the frequency of their activities. The study involved 154 survey participants, or 17.1% of the target case managers in the State of Victoria, Australia. Key information collected included participants' socio-demographic characteristics, proportions of time allocated to six core case management functions, and frequency ratings of 41 specific activities within seven case management functions. Ordinal regression analyses were performed to determine significant factors associated with participants' frequency ratings of their activities. Participants allocated the largest proportion of time to care coordination (22.0%), and the smallest proportion of time to outcome evaluation (8.0%). Over 70% of the participants assigned high frequency ratings to 31 of the 41 case management activities. The remaining ten activities, including all four outcome evaluation activities, three needs assessment activities, one care planning activity, one care coordination activity, and one general functions-related activity were less commonly performed very frequently. The regression analyses indicated that some case manager and client factors were significantly associated with frequency ratings of nine of the ten activities aforementioned. The two main findings of the regression analyses were: First, emphasising achieving more case management goals was significantly associated with higher frequency of three outcome evaluation activities; second, longer work experience was significantly associated with higher frequency of one care coordination activity and one outcome evaluation activity. The frequent performance of most case management activities and relative absence of factors influencing their

    To evaluate whether the frequencies of placenta lacunae and lack of a clear zone are higher in cases of placenta previa compared with those without it. Ultrasonographic findings just before delivery, including placenta lacunae and lack of a clear zone were prospectively evaluated in consecutive subjects. After collection, a case-control study with 1:5 matched pairs was conducted. The frequencies of ultrasonographic findings were analyzed in cases with placenta previa and normal placenta. Seventy cases with placenta previa and 350 cases with normal placentas were observed. Five and zero cases with abnormal placental adherence were observed in cases with placenta previa and normal placenta, respectively. Lack of a clear zone was observed in 60 and 1.5% of cases with and without the placental adherence (p = 0.001). Placenta lacunae and lack of a clear zone were observed in 31.4 and 9.7% of cases with and without placenta previa [odds ratio (OR) 4.2]. Lack of a clear zone was observed in 5.7 and 0.9% of cases with and without placenta previa (OR 7.0). Placenta lacunae and lack of a clear zone are frequently observed in placenta previa even when there is no adherence of the placenta. Copyright © 2011 John Wiley & Sons, Ltd.

    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

    It is estimated that the standard, passive case finding (PCF) strategy for detecting cases of tuberculosis (TB) in Myanmar has not been successful: 26% of cases are missing. Therefore, alternative strategies, such as active case finding (ACF) by community volunteers, have been initiated since 2011. This study aimed to assess the contribution of a Community Based TB Care Programme (CBTC) by local non-government organizations (NGOs) to TB case finding in Myanmar over 4 years. This was a descriptive study using routine, monitoring data. Original data from the NGOs were sent to a central registry within the National TB Programme and data for this study were extracted from that database. Data from all 84 project townships in five regions and three states in Myanmar were used. The project was launched in 2011. Over time, the number of presumptive TB cases that were referred decreased, except in the Yangon Region, although in some areas, the numbers fluctuated. At the same time, there was a trend for the proportion of cases treated, compared to those referred, that decreased over time (P = 0.051). Overall, among 84 townships, the contribution of CBTC to total case detection deceased from 6% to 4% over time (P < 0.001). Contrary to expectations and evidence from previous studies in other countries, a concerning reduction in TB case finding by local NGO volunteer networks in several areas in Myanmar was recorded over 4 years. This suggests that measures to support the volunteer network and improve its performance are needed. They may include discussion with local NGOs human resources personnel, incentives for the volunteers, closer supervision of volunteers and improved monitoring and evaluation tools.

  12. Neuroradiological, neurophysiological and molecular findings in infantile Krabbe disease: two case reports

    Full Text Available Krabbe disease is an autosomal recessive neurodegenerative disorder due to a defect of the lysosomal enzyme β-galactocerebrosidase (β-GALC. Depending on the age of onset, the disease is classified into infantile and later-onset forms. We report neuroradiological, neurophysiological and molecular findings in two Greek patients with the infantile form of Krabbe disease. The index patients presented at the age of 3.5 and 6 months, respectively, due to developmental delay. Magnetic resonance imaging (MRI of the first patient’s brain demonstrated signs of leukodystrophy, while nerve conduction velocities (NCVs were significantly decreased. The second patient’s MRI at the age of 4 months was initially normal, but at 18 months demonstrated leukodystrophic alterations as well, whereas NCVs were also significantly delayed. In both patients, a severe decrease in β-GALC, activity supported the diagnosis of Krabbe disease, while the final diagnosis was confirmed by molecular genetic testing. Two homozygous mutations of the GALC gene, the c.411_413delTAA [p.K139del] mutation in the first patient, and the c.749T>C [p.I250T] mutation in the second patient, were identified. At their last follow-up visit at the age of 4 and 6 years, respectively, both patients were bedridden and quadri-plegic, suffering from frequent respiratory tract infections and fed through a gastrostomy. Both mutations found in homozygosity in these two unrelated patients of Greek ancestry, could pinpoint a common origin. Genotyping of patients with Krabbe disease is important, in order to contribute to the creation of a European mutation database and to further study possible genotype-phenotype correlations of the disease.

    Full Text Available Intrastromal corneal ring segments (INTACS implantation for mild myopia or keratoconus is simple and effective in most cases. Rarely, major complications can occur due to implantation. In this case report, we present two examples of possible intraoperative and postoperative complications of INTACS. The first case had histopathologic documentation of Descemet′s membrane perforation as an intraoperative complication and the second case had accumulation of foamy histiocytes along the lamellar channels which has not been previously reported. These complications suggest further study is required on the long term effect of INTACS implantation on corneal tissue.

    Jugular bulb diverticulum is a rare condition that is characterized by the outpouching of the jugular bulb, and this can lead to hearing loss, tinnitus and vertigo. A few reports have revealed the radiologic findings about jugular bulb diverticulum, but none of them have described the MRA findings concerning this lesion. We present here the CT and MR venography findings in regards to a large high jugular blub and diverticulum we observed in a 47-year-old woman.

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.

    2008-01-01

    This work clarifies the relation between network circuit (topology) and behaviour (information transmission and synchronization) in active networks, e.g. neural networks. As an application, we show how one can find network topologies that are able to transmit a large amount of information, possess a large number of communication channels, and are robust under large variations of the network coupling configuration. This theoretical approach is general and does not depend on the particular dynamic of the elements forming the network, since the network topology can be determined by finding a Laplacian matrix (the matrix that describes the connections and the coupling strengths among the elements) whose eigenvalues satisfy some special conditions. To illustrate our ideas and theoretical approaches, we use neural networks of electrically connected chaotic Hindmarsh-Rose neurons. PMID:18941516

    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.

    1990-08-01

    A diagnostic approach based on clinical and radiographic examinations for evaluation of young foals and small ponies with acute abdominal discomfort is presented. Standing right to left lateral abdominal radiographs were taken of 54 foals and 6 ponies using a previously described technique. Interpretation of the radiographs was in conjunction with all clinical and laboratory findings and patient management. Using this approach, the site and cause of acute abdominal discomfort could be diagnosed accurately in 55 of 60 (91%) patients as confirmed by clinical, surgical or necropsy findings. Typical radiographs and photographs taken at surgery or at necropsy are presented. Typical radiographic findings, their interpretation and possible underlying gastrointestinal diseases are listed. The incorporation of standing lateral abdominal radiography in the clinical evaluation of foals and ponies with acute abdominal diseases gives findings of high diagnostic significance and should contribute to clinical decision-making. Abdominal radiography can replace data from rectal palpation in foals and ponies.

    2016-06-01

    Full Text Available Introduction Multiple unilateral congenital diaphragmatic hernias (CDH are extremely rare, described only five times in the medical literature. Concurrent ipsilateral Bochdalek and Morgagni hernias are rarer still with only two cases previously described. In all reported cases of multiple concurrent defects, the hernias were repaired in an open fashion, either via a thoracotomy or laparotomy with both of the two combined Bochdalek and Morgagni hernias repaired via laparotomy. Case Presentation In this case report we have a 2-day-old who developed respiratory distress and on CT scan was found to have a congenital diaphragmatic hernia (CDH or eventration. This patient is ideal for this case report because he meets a lot of the previously established criteria for minimally invasive repair of congenital diaphragmatic hernias - minimal respiratory compromise, no congenital heart defects - and he has synchronous defects which have very rarely been seen before. Here we present the first reported case of concurrent ipsilateral Bochdalek and Morgagni hernias repaired in a one-stage minimally invasive fashion, approaching the Bochdalek hernia thoracoscopically and the Morgagni laparoscopically. The patient had a quick recovery post-operatively and he continues to do well. Conclusions From this experience, we argue that in the right circumstances a completely minimally invasive approach can be taken for synchronous congenital diaphragmatic hernias.

    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.)

    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.

    This paper provides a detailed 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 relative influences of context factors (policy mix, market factors and public acceptance) and firm characteristics (value chain position, technology portfolio, size and vision). Empirically, our qualitative analysis is based on multiple case studies with 19 power generators, technology providers and project developers in the German power sector which were conducted in 2008/09. We find that the innovation impact of the EU ETS has remained limited so far because of the scheme's initial lack of stringency and predictability and the relatively greater importance of context factors. Additionally, the impact varies significantly across technologies, firms, and innovation dimensions and is most pronounced for RD and D on carbon capture technologies and organizational changes. Our analysis suggests that the EU ETS on its own may not provide sufficient incentives for fundamental changes in corporate innovation activities at a level which ensures political long-term targets can be achieved.

    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.

    Full Text Available Neuropathic arthropathy of the shoulder is reported in only 5% of cases. Here, we report a rare case of neuropathic arthropathy of the shoulder, secondary to Chiari malformation Type I with associated syringomyelia, that remained undetected for four years. A 38-year-old female presented to our Department with a swelling over the right shoulder that had persisted for four years. X-ray of the joint showed destruction of the head of the right humerus, with typical blunt amputated appearance of the bone and increased joint space. Magnetic resonance imaging showed destruction and lateral dislocation of the head of the humerus. Large amount of fluid collection was seen in and around the right shoulder joint. Neuropathic osteoarthropathy can be defined as bone and joint changes that occurs secondary to loss of sensation. In our case, neuropathic shoulder joint was secondary to syringomyelia associated with Chiari I malformation.

    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.).

    Bee sting therapy is a folk remedy used for arthralgia. An adverse reaction to bee sting therapy can be variable, ranging from a local inflammatory reaction to generalized anaphylaxis. There have been reports of dermatologic findings pertaining to bee sting granulomas, which results from a foreign body reaction to the persistence of venom and stinger at the sting site. However to the best of our knowledge, the radiologic findings of bee sting granulomas have not been reported on in Korea. We describe the ultrasound and MRI findings of bee sting granulomas at the lower extremity in a 36-year-old woman who underwent bee-sting therapy for osteoarthritis of the knee joints 3 months prior.

    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.

    Reduction en masse of inguinal hernia is an extremely rare complication arising from manual reduction of a hernia. The hernial content remaining in the hernia sac returns above the inguinal canal but remains in the abdominal wall. Accurate preoperative diagnosis of reduction en masse of inguinal hernia is challenging because the hernia appears to be reduced upon physical examination. We experienced two cases of reduction en masse. In both cases, multidetector row computed tomography revealed a closed loop obstruction near the inguinal fossa. In addition, we observed a continuous tract of the hernia sac to the inguinal canal and prominent peritoneal thickening suggestive of the hernia sac.

    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.

    Wernicke's Encephalopathy is an acute neuropsychiatric syndrome that can be seen in both alcohol abusers and non-alcoholic population as a result of thiamine deficiency. We herein report a non-alcoholic patient with typical clinical presentations but atypical MRI findings. Early clinical suspicion of WE is especially important in non-alcoholic patients with atypical MRI findings. The diagnosis of this group is more difficult to make and the prognosis of the syndrome mostly depends on early initiation of thiamine supplementation. PMID:26306933

    A large cell neuroendocrine carcinoma of the stomach is extremely rare. We have reviewed the medical records and imaging studies of the four patients that presented with a large cell neuroendocrine carcinomas of the stomach. On a barium study and CT imaging, a gastric large cell neuroendocrine carcinoma is depicted as an ulcerofungating tumor with minimal peritumoral infiltration and metastatic lymphadenopathy in the perigastric area. These findings are similar to findings for advanced gastric cancer, especially Borrmann type II. However, a gastric large cell neuroendocrine carcinoma is highly malignant with a significantly worse prognosis than a usual adenocarcinoma.

    A supravesical hernia occurs in the supravesical fossa and is either classified as an external or internal supravesical hernia. Most patients with internal supravesical hernias present with small bowel obstruction. Internal supravesical hernias are less common than external supravesical hernia. To date, there are few reports describing the radiological findings of supravesical hernias. To our knowledge, this is the first reported multidetector row CT (MDCT) depiction of this type of hernia. We report here on the MDCT findings of a patient with an internal supravesical hernia presenting with small bowel obstruction

    Patau syndrome (trisomy 13) is one of the most common chromosomal anomalies clinically characterized by the presence of numerous malformations with a limited survival rate for most cases. Babies are usually identified at birth and the diagnosis is confirmed with genetic testing. In this review we outline the clinical and cytogenetic aspects of trisomy 13 and associated phenotypes for 5 cases analyzed in the last 3 years, referred to our Clinical Genetics Department. For each child cytogenetic analysis was performed to determine the genetic variant; also, the patients were investigated for other associated malformations (cardiac, cerebral, renal, ocular anomalies). All 5 cases presented multiple malformations, including some but not all signs of the classical clinical triad suggestive of Patau syndrome. The cytogenetic investigation confirmed for each case the suspected diagnosis and also indicated the specific genetic variant, this being a valuable information for the genetic counselling of the families. The application of genetic analysis can increase diagnosis and prognosis accuracy and have an impact on clinical management.

    This study analyzed students' written reflections following their initial exposure to interprofessional teamwork in case-based problem-solving. A three-hour seminar featuring three sequenced scenarios was developed and offered 12-times over two semesters. A total of 305 students from a variety of healthcare programs worked together with standardized patients in an on-campus laboratory simulating hospital ward and rehabilitation settings. A thematic analysis of students' reflections showed that they valued the shared learning and realistic case study. However, they felt the experience would be strengthened by working in smaller, more representative teams that included students from medicine, psychology, and social work to enable more effective communication and comprehensive case discussion. While useful for future planning, the identified themes did not enable a comparative statistical analysis of what students found helpful and difficult and a re-coding of students' responses now is underway. Implications for measuring the effectiveness of future interprofessional case-based learning center on addressing the identified weaknesses, and establishing a research design that enables a comparison of pre- and post-seminar data, and the effectiveness of the IPE experience compared to profession-specific experiences.

    The use of single-case methodology (SCM) in brain injury rehabilitation is described and contrasted with other methodologies. SCM is optimal when attempting to meet highly individual presentations or to trial innovative solutions. Portable biofeedback is a potentially effective means of helping persons with brain injury to recognise and regulate emotional states. Emotional dysregulation, associated with disinhibition on tests of executive function, is hypothesised to underpin aggressive challenging behaviour and may be amenable to feedback on heart rate variability, a marker for stress. Two case studies of a novel biofeedback intervention, emWave2, to address aggression directed towards the self and towards others are presented. Data from two A-B designs were analysed using the non-overlap all pairs (NAP) statistical method. Clinical significance of outcome is reported in both cases but only Case 2 reached statistical significance. The discussion highlights limitations of the methodology. Results are discussed in relation to the device helping participants differentiate the physiological state associated with stress. The future application of wearable physiological sensing and feedback systems is explored.

    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.

    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.

    Amyotropic lateral sclerosis(ALS) is a progressive degenerative illness of unknown cause; we present its characteristic brain magnetic resonance(MR) findings in one patient. A 58-year-old woman who for two years had been suffering from progressive motor weakness and dysarthria was admitted to our hospital. Physical examination and laboratory findings showed a pattern of both upper and lower motor neuron disease such as decreased motor power(Grade 3), tongue atropy, increased deep tendon reflex, a pattern of lower motor neuron disease, as seen on electromyogram, and a pattern of sparing sensory nervous system, extraocular muscle movement, bladder, and bowel function. On axial brain MR proton-density and T2-weighted images, small round areas of high signal intensity were seen bilaterally in the posterior limb of the internal capsule; these corresponded to the corticospinal tract. Additionally, bilateral, subtle lineal low signal intensity in the precentral gyrus was noted on T2-weighted imaging. On the basis of the findings of clinical and laboratory examination, and of typical MR imaging findings, ALS was diagnosed.

    Objective: To retrospectively review the imaging features of surgically and pathologically confirmed intracranial hemangiopericytoma and anaplastic hemangiopericytoma. Methods: Thirty-nine cases of surgically and pathologically confirmed hemangiopericytoma and anaplastic hemangiopericytoma were analyzed retrospectively. The MRI features were compared with pathological findings in all cases. Results: Of the 39 cases, 21 were anaplastic hemangiopericytoma (WHO grade III) and the remaining cases were hemangiopericytoma (WHO grade II); all lesions were solitary. MRI of anaplastic hemangiopericytoma showed that 20 cases were lobulated, and nine grew cross-leaf. The lesions showed mixed iso-high-low signal (n = 20) or iso-signal (n = 1) on plain T1WI, and mixed high-low signal (n = 20) or iso-signal (n = 1) on plain T2WI. After contrast injection, marked heterogeneous enhancement was seen in 19 cases. Significant necrosis and cystic changes were seen in 16 cases, and the 'dural tail sign' was found in two cases. Ten cases had bony destruction, and 16 showed significant peritumoral edema. In 18 cases of hemangiopericytoma, nine were oval-shaped and three grew cross-leaf. The lesions showed mixed iso-low signal (n = 10) or iso-signal (n = 8) on plain T1WI, and mixed iso-high signal (n = 10) or iso-signal (n = 8) on plain T2WI. After contrast injection, significant uniform enhancement was seen in 10 cases. Significant necrosis and cystic changes were seen in seven cases, and 'dural tail sign' was seen in six cases. Two cases had bony destruction. No case showed significant peritumoral edema. Pathological immunohistochemical Ki67 staining showed a concentration of {approx}18.4% positive cells in anaplastic hemangiopericytoma, whereas in hemangiopericytoma it was 7.12%. Conclusion: Imaging findings of intracranial anaplastic hemangiopericytoma had more pronounced lobulation, cross-leaf growth tendency, more and easier bleeding, more necrosis, more cystic

    Background: It is recognized that patients who undergo endoscopic sinus surgery (ESS) do not always achieve control of their disease. The causes are multifactorial; variations in surgical practice have been identified as possible factors in refractory disease. Objective: To reflect on the frequent anatomic findings of patients with chronic rhinosinusitis (CRS) who require revision ESS. Methods: A retrospective review of patients who required revision ESS at a tertiary institution over a 3-year period. Patients for whom maximal medical therapy failed for CRS underwent computed tomography of the paranasal sinuses and image-guided surgery. Surgical records of anatomic findings were reviewed and analyzed. Results: Over 3 years, a total of 75 patients underwent revision procedures, 28% of all ESS performed in the unit. The most frequent finding was a residual uncinate process in 64% of the patients (n = 48); other findings included a maxillary antrostomy not based on the natural ostium of the maxillary sinus in 47% (n = 35), an oversized antrostomy in 29% (n = 22), resected middle turbinates in 35% (n = 26), middle meatal stenosis in 15% (n = 11), synechiae in 29% (n = 22), and osteitic bone that required drilling in 13% (n = 10). Conclusion: Surgical technique can give rise to anatomic variations that may prevent adequate mucociliary clearance and medication delivery, which leads to failure in ESS in patients with CRS. This study demonstrated the surgical findings encountered in revision ESS that should be highlighted in the training of Ear, Nose and Throat surgeons to help prevent primary failure and reduce health care costs.

    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

    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.

    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.

    2012-01-01

    Full Text Available Conjoined twins are rare variants of monozygotic twins, which result from an incomplete division of the embryonic disk. Cephalothoracopagus is a rare twin pregnancy described as imperfect fusion of the head and chest, but separated columns, limbs, and pelvis. They occur with incidence rates that range from 1 per 50,000 to 1 per 100,000 births; however, the incidence of the cephalothoracopagus variety is 1 per 58 conjoined twins. In the case of identical and symmetric faces caused by the orientations of the 2 notochordal axes that are perfectly ventroventral, they are called janiceps disymmetros. We present a prenatal diagnosis of a typical case of cephalothoracopagus janiceps disymmetros and the diagnostic confirmation by image and pathology exams.

    To describe the normal ultrasonographic appearance of the temporomandibular joint (TMJ) in cattle, and to describe the ultrasonographic pathology of the TMJ as assessed in one cow with TMJ disease. The TMJ of 12 healthy Holstein-Friesian cows were examined using a portable ultrasonographic unit with a 7.5 MHz linear probe and a 6.0 MHz convex probe. Each TMJ was scanned in a rostrolateral, lateral and caudolateral plane. In addition, the TMJ of one 2-year-old cow with clinical signs of food retention in the mouth, head tilt, swelling and pain in the right TMJ region and an infected horn fracture was examined ultrasonographically. The bone surfaces of the temporal process, the zygomatic process and the temporal bone, the larger muscles of the TMJ region, the superficial temporal vein, and the parotid salivary gland could be imaged in all normal healthy cattle. Using the linear probe, the joint capsule was visible in 17/24 (71%) cases in the caudolateral plane, but the articular disc could not be visualised. With the convex probe, the joint capsule could be imaged in all cases in the caudolateral plane, and the articular disc in 13/24 (54%) cases in the caudolateral plane. It was never possible to see the synovial pouch in healthy cattle using either probe. By contrast, in the cow diagnosed with septic arthritis of the right TMJ, a marked anechoic and heterogeneous hypoechoic effusion of the TMJ with distension of the joint capsule was visualised. The results of this descriptive study serve to provide a reference for ultrasonography of pathological conditions of the TMJ region in cattle. As many veterinarians are equipped with ultrasound machines with 5-8 MHz linear rectal probes, the authors recommend using these probes for further investigation of clinical cases with swelling of the TMJ region and/or masticatory problems of unclear origin to exclude or diagnose TMJ disorders.

    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.

    Carotidynia is a rare disease representing various aspects of pain around the carotid artery bifurcation. The pain in the carotid bifurcation area is a nonspecific symptom, and various diseases causing similar symptoms in the corresponding area should be distinguished. Mostly, carotidynia is diagnosed by history taking and physical examination, but it is not easy to distinguish carotidynia from other diseases without imaging study. Therefore, there are quite a number of inadequate treatments due to a considerable number of misdiagnosis, as infectious diseases. In US, CT scans, and MRI examinations, the authors experienced a patient who showed the outer thickening wall of blood vessels around the carotid artery, near the carotid artery bifurcation, and was diagnosed as carotidynia with clinical findings. In the follow up that was carried out two weeks later, the thickness of the lesions was significantly decreased. Imaging studies are helpful in the differential diagnosis because carotidynia shows relatively characteristic imaging findings.

    Congenital rib abnormalities are found in approximately 2% of the general population. Usually, they occur in isolation, when they are rarely symptomatic, but they can also associate with other malformations. We reviewed imaging examinations performed over a period of two years (2014-2015), enabling us to identify isolated rib abnormalities in six adult patients. The case series consisted in three cases with bilateral cervical ribs and one case each with bifid rib, costal fusion and rib pseudarthrosis. In all patients, the costal anomalies were discovered incidentally. All rib malformations were detected at thoracic radiography, except for the rib pseudarthrosis, which was identified at CT scan. Differential diagnosis was made between cervical ribs and abnormalities of the C7 transverse process and of the first rib, while the other costal malformations were distinguished from tumoral, traumatic or inflammatory lesions of the chest wall, lung and pleura. Considering the existing knowledge on rib development, we suggest a classification of the most common types of rib malformations in three categories: (I) results of homeotic transformation, referring to numerical aberrations; (II) segmentation errors, including costal fusion and bridging; (III) anomalies of resegmentation, resulting in bifid ribs. It is important that radiologists are familiarized with the imaging features of rib abnormalities, since these anomalies can be misinterpreted as lesions with different implications. We aim that the developmental classification proposed in this paper can contribute to a better understanding of this pathology.

    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.

    Full Text Available Introduction. The objective is to report a case of Cornelia de Lange syndrome (CdLS diagnosed by detailed observations using three-dimensional sonography. Case Report. A 33-year-old healthy multipara was referred to our hospital at 34-week gestation after severe fetal growth restriction, congenital heart anomaly, and antebrachium abnormality were diagnosed during the third trimester. Further sonography diagnosis on cardiac abnormalities diagnosed the existence of ventricular septal defect in the outflow tract, atrioventricularis communis, and truncus arteriosus communis where the pulmonary artery branched from the common arterial trunk. As for abnormalities of the forearms, ectrodactylia and monodactylism were suspected and the abnormalities were observed sterically by using three-dimensional sonography. A 1986 g (1.07 percentile male newborn was delivered by assisted breech extraction at 37-week gestation. After birth, from characteristic facies including bushy eyebrow, broad nasal bridge, micrognathia, and abnormalities of the forearms (ectrodactylia and monodactylism, the case was diagnosed with CdLS. Conclusion. Through detailed observation including abnormalities of fingers, we could exemplify this very rare disease as an antenatal diagnoses for fetal growth retardation.

    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 magn...

    Imaging findings of urinary tuberculosis (TB) on excretory urography (IVP) and CT have been reported to be nonspecific although CT may provide detailed informations. We performed a retrospective study of patients with proven urinary TB to compare imaging findings on IVP and CT and to make a systemic approach to imaging analysis of urinary TB. Urinary TB was diagnosed in 46 patients who had IVP and CT examinations prior to definitive diagnosis and treatment. They were 30 females and 16 males with a mean age of 43.6 ys. We assessed the presence and frequency of urinary tract calcifications, autonephrectomy, renal parenchymal masses, renal parenchymal scarring, moth-eaten calices, amputated infundibulum, renal parenchymal cavities, hydrocalycosis, hydronephrosis, hydroureter and thick urinary tract walls. CT was most sensitive in detecting any renal parenchyma cavities (p=0.01), hydronephrois (p=0.0005), ureteral stricture (p=0.03) and walls thickening of the renal pelvis / ureter (purinary tract walls were significantly more common on CT than on IVP. Multiple findings on CT were more common and very useful for TB diagnosis. Thus, we recommend CT as the standard exam in patients with suspicion of urinary TB.

    Summary Background Pentalogy of Cantrell (POC) is an extremely rare and complex congenital anomaly. Ultrasound is a valuable, safe, nonionizing, cost effective, widely available, and easily reproducible imaging tool and is indispensible in the diagnosis of POC. Despite the rarity of POC, it is imperative for a radiologist to be aware of its wide spectrum of presentation on ultrasound in first trimester of gestation. Most reported cases in literature till now have been sporadic. In this paper, we aimed to report for the first time in literature, a recurrent case of POC detected in the first trimester in a mother whose previous pregnancy also was terminated in the second trimester medically due to the ultrasound diagnosis of POC. We also discuss the role of ultrasound and other imaging modalities in a case of POC as well as the differential diagnoses which can mimic POC. Case Report A 23-year-old G2P0A1 (Gravida2, para0, abortion1) woman with a gestational age of around 12 weeks was referred for a routine first trimester ultrasound scan. The antenatal ultrasound scan showed a single, live, intrauterine gestation corresponding to a gestational age of 11 weeks and 5 days. The fetal heart was visualized outside the chest through a defect in the lower sternum in association with anterior diaphragmatic and ventral abdominal wall defects suggestive of thoraco-abdominal variety of ectopia cardis. There was a membrane covered, midline, abdominal wall defect at the base of the umbilical cord insertion containing the herniated abdominal organs including the liver, bowel loops and the ectopic cardia. There was a breach in the normal outline of the lower sternum indicating a sternal deficiency. The fetal pericardium was absent. The nuchal translucency was grossly increased. Pentalogy of Cantrell was diagnosed on ultrasound and the patient was explained about the poor prognosis of this condition. An informed consent was obtained after she opted for medical termination of

The objective of this study was to assess the feasibility and effectiveness of COPD case-finding service provided by community pharmacists, utilizing a combination of risk assessment questionnaire and microspirometry. Methods: A 6-month service was conducted in 21 community pharmacies in Australia. Pharmacists trained in COPD case finding, including lung function test (LFT, invited their patients aged ≥35 years with a history of smoking and/or respiratory symptoms to participate. High-risk patients were identified via a COPD risk assessment questionnaire (Initial Screening Questionnaire [ISQ] and underwent LFT. Pharmacists referred patients with a forced expiratory volume in 1 second (FEV1/forced expiratory volume in 6 seconds (FEV6 ratio <0.75 to their general practitioner (GP for further assessment and diagnosis. Results: In all, 91 of 167 (54% patients had an ISQ score >3 indicating high COPD risk. Of the 157 patients who were able to complete LFT, 61 (39% had an FEV1/FEV6 ratio of <0.75 and were referred to their GP. Patients with high ISQ symptoms scores (>3 were at a significantly higher risk of an FEV1/FEV6 ratio of <0.75, compared to patients with fewer COPD symptoms. A total of 15 (10% patients were diagnosed with COPD by their GP. Another eight (5% patients were diagnosed with other medical conditions and 87% of these were initiated on treatment. Although only half of all screened patients lived in regional areas, 93

    Acute calcific tendinitis of the shoulder is a well-known condition, but it is rare in the rectus femoris origin. Mostly reported cases were occurred in the reflected head of the rectus femoris, and only few cases were in the direct head of the rectus femoris. Intraosseous marrow involvement of calcific tendinitis is a more rare condition; it often goes misdiagnosed as an infection or a neoplasm. We report a rare, unusual case of acute calcific tendinitis of the direct head of the rectus femoris associated with intraosseous marrow involvement of calcification in anterior inferior iliac spine with serial CT and MRI findings. Aggressive osseous change may occur in acute calcific tendinitis of the rectus femoris as in this case which should be made an appropriate diagnosis to avoid unnecessary investigation and overtreatment like a surgery.

    Full Text Available Abstract Background Myoepithelioma of the breast is a rare tumor and the cytologic features have only been described in one previous report. Case presentation The present case comprises a 70 year old woman with a mammographic equivocal and ultrasonographic suspicious lesion. The aspirates were cellular and consisted mainly of single spindle or polymorphic, polygonal cells. The nuclei were generally large, ranging from 2 - > 5 × RBC. Most nuclei had a distinct medium-sized nucleolus. The nuclear outlines were irregular with buds and folds. The chromatin was granular. In the background there was abundant granular metachromatic ground substance and some metachromatic stromal fragments. A few mitotic figures were found. The cytologic diagnosis was suspicious for malignancy and a metaplastic carcinoma where only the non-epithelial component had been aspirated, or a non-epithelial lesion, was suggested. Macroscopically the tumor was round, seemingly well circumscribed, firm and with a white cut surface. The lesion consisted of spindled and polygonal cells with distinct pleomorphism. There were 6–9 mitoses per high power field (HPF. The tumor infiltrated in the surrounding fatty tissue. On immunohistochemistry, tumor cells were positive for smooth muscle actin, keratin MNF 116 and vimentin. Desmin and S-100 were negative. Ultrastructurally, there were abundant tonofilaments, including globular filamentous bodies and granulated endocytoplasmic reticulum with many dilated cisterns. The histologic diagnosis was malignant myoepithelioma. Conclusion The case mirrors completely the WHO definition and the previous cytological and histological descriptions of malignant myoepitheliomas in the literature which describe a spindle cell population with unequivocal nuclear atypia, metachromatic background substance and mitoses.

    Although the clinical features of gluteus maximus contracture syndrome have been frequently described, imaging features have been seldom described. Most commonly reported cases are those following intramuscular injection in the gluteal region although congenital contracture is an uncommon but important occurrence. This condition has most often been reported in children of school going age. These patients often present with difficulty in squatting, limitation of hip motion or specific deformities and often require surgical correction. We describe the plain radiography, ultrasonography (USG) and magnetic resonance imaging (MRI) features of this condition in a patient with no previous known history of intramuscular injections.

    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.)

    The spread of tuberculosis in a university environment following a case of cavitary disease was studied. Six loci of potential secondary infection were ascertained and the persons at risk were identified for tuberculin screening. All named contacts were ranked by the index patient and her friends on a closeness scale for social contact. This scale proved to be an excellent predictor of tuberculin positivity, suggesting that in a noninstitutionalized setting the risk of tuberculin conversion is associated more with social contact than with mere living proximity.

We describe a case of rhino-orbital mucormycosis with orbital cellulitis and paranasal sinusitis, as seen on initial MR images, which on follow-up images had evolved to orbitofacial infarction. MR imaging was useful for the demonstration of orbitofacial infarction, seen as areas of lack of enhancement and thus suggesting vascular involvement by mucor hyphae. (author)

    Full Text Available We present here a rare case of rupture of tunica albuginea and corpus cavernosum, in the site of a Peyronie’s plaque, which happened in a 61- year-old man during a vacuum cleaner masturbation. Ultrasound study showed an irregular hyperechoic defect at the cavernosal rupture site in correspondence of the Peyronie’s plaque. The hematoma was evacuated, partially plaque excised, and the tear repaired. Ultrasonography is an ideal technique for evaluating patients with penile trauma and can be routinely used in an emergency. It is a non-invasive method that gives faster results than cavernosography and Magnetic Resonance Imaging.

    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.

    Angiomyolipoma with epithelial cysts (AMLEC) or cystic angiomyolipoma has been recently described as a distinct cystic variant of angiomyolipoma. Although angiomyolipoma (AML) is usually composed of adipose, vascular, and muscular tissue lacking an epithelial element, AMLEC contains an epithelial component in the form of gross or microscopic cysts. To date, the radiologic appearance of AMLEC has been demonstrated in only one case report, as a solid mass containing a tiny cystic focus. This report shows another imaging feature of AMLEC, which presents as a multiloculated cystic mass without a visible solid portion on CT and MRI

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

    Pica is a compulsive eating of non-nutritive substances and can have serious medical implications. The causes are not known, but the symptom is often associated iron-deficiency. Pica is an under-diagnosed problem. Although few dental problems associated with pica have been reported, because of its potential impact on blood measures, dental professionals must be aware of this common, but commonly missed, condition. This is an unusual case of a patient diagnosed with aggressive periodontitis (AgP) who had a dirt eating habit (geophagia) and was diagnosed as having pica.

    This report presents a rare case of leptomeningeal carcinomatosis initially presenting with mental impairment and rapidly progressing to coma without any history of malignancy. In addition to highlighting the diagnostic difficulties, the linear high signal intensity along the cortex on the diffusion-weighted imaging (DWI) sequence of magnetic resonance (MR) imaging was identified accidentally. High signal change in the corresponding areas was also noted on unenhanced fluid-attenuated inversion recovery (FLAIR) MR imaging, which may be a novel method of diagnosing leptomeningeal carcinomatosis, which should be studied further.

    Intraosseous pneumatocyst of the ilium is a rare lesion of uncertain origin. It predilects male subjects and may be associated or not with sacroiliac joint degenerative disease, intra-articular gas, sacral pneumatocyst, and communication with the articular space. To our knowledge, only 16 observations have been reported in the literature. We have evaluated with plain radiographs and CT two additional cases. Plain films frequently identify these lesions, but CT is the method of choice in demonstrating their air density and assessing the possible abnormalities of the surrounding bone and sacroiliac joints.

    We report a case of malignant melanoma of Eustachian tube with extension to the middle ear cavity and nasopharynx in a 51-year-old woman who presented with right ear fullness. Computed tomography showed a soft tissue mass in the middle ear cavity and caused the widening and eroding of the bony eustachian tube. Magnetic resonance imaging showed well enhancing mass in eustachian tube extending nasopharynx to middle ear cavity. A biopsy of the middle ear cavity mass revealed a malignant amelanotic melanoma.

    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

    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.

  4. Bone scan findings in calcific tendinitis at the gluteus maximus insertion: some illustrative cases

    2017-03-01

    Full Text Available We describe the bone scan and single-photon emission computed tomography/computed tomography findings in calcific tendinitis of the gluteus maximus and discuss its pathophysiology. Although this tendinopathy is mostly self-limiting, awareness of this disease is important for 2 reasons. First, it may explain acute hip symptoms in patients in the resorptive phase of the calcifications. Second, it should be considered as a differential diagnosis for bone scan hot spots in the vicinity of the gluteus maximus tendon and for cortical erosion seen in that region on X-rays or CT.

    We histopathologically examined a surgically resected full specimen obtained from an early-stage spontaneous osteonecrosis of the knee (SPONK). On a mid-coronal cut section of the resected medial femoral condyle, a linear fracture line paralleling the subchondral bone endplate was found. Histopathologically, prominent callus formation was seen comprising of reactive woven bone and granulation tissue on both sides of the fracture. Fracture-related bone debris was focally observed at the osteochondral side of the fracture. Definitive features of antecedent bone infarction such as creeping substitution and bone marrow necrosis were not detected. These findings suggested that SPONK was the result of a subchondral fracture rather than primary osteonecrosis.

    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

    Using the Photonics Leaders program model, recruitment and retention, photonics content, parental engagement, internship, and PHOTON PBL challenges, the session's goal is to inform educators of strategies that can be used to motivate and develop cognitive skills in the discipline of Physics. The program caters to ethnically diverse students who traditionally lack experiences in the discipline. This paper discusses the initial findings of the National Science Foundation (NSF) Innovative Technology Experiences for Students and Teachers (ITEST) program through which high school students and teachers were given the opportunity to participate in shared lessons, and coordinate projects through cooperative learning at The Science House at North Carolina State University.

    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.

    Hyperhidrosis is caused by a sympathetic dysfunction of the central or peripheral nervous system. Intramedullary spinal cord lesions can be a cause of hyperhidrosis. The authors report a rare case of intramedullary thoracic spinal cord ganglioglioma presenting as hyperhidrosis. This 16-year-old boy presented with abnormal sweating on the right side of the neck, chest, and the right arm that had been occurring for 6 years. Neurological examination revealed mild motor weakness of the right lower extremity and slightly decreased sensation in the left lower extremity. Hyperhidrosis was observed in the right C3-T8 dermatomes. Magnetic resonance imaging showed an intramedullary tumor at the right side of the spinal cord at the T2-3 level. The tumor showed partial enhancement after Gd administration. The patient underwent removal of the tumor via hemilaminectomy of T2-3. Only subtotal resection was achieved because the margins of the tumor were unclear. Histopathological examination revealed ganglioglioma. Hyperhidrosis gradually improved after surgery. Hyperhidrosis is a rare clinical manifestation of intramedullary spinal cord tumors, and only a few cases have been reported in the literature. The location of the tumor origin, around the right gray matter of the lateral spinal cord, may account for the hyperhidrosis as the initial symptom in this patient. Physicians should examine the spinal cord using MRI studies when a patient has hyperhidrosis with some motor or sensory symptoms of the extremities.

    At 17(+4) week, non-invasive prenatal testing (NIPT) results of a 24-years-old mother showed high risk of monosomy X (45, X). Abnormally shaped head and cardiac defects were observed in prenatal ultrasound scan at 19(+3) week. Amniocentesis conducted at 19(+3) week identified karyotype 47, XX, +18, which suggested that the NIPT failed to detect trisomy 18 (T18) in this case. With a further massively parallel sequencing (MPS) of maternal blood, fetal and placental tissues, we found a confined placental mosaicism (CPM) with non-mosaic T18 fetus and multiclonal placenta with high prevalence of 45, X and low level of T18 cells. FISH and SNP-array evidence from the placental tissue confirmed genetic discrepancy between the fetus and placenta. Because the primary source of the fetal cell-free DNA that NIPT assesses is mostly originated from trophoblast cells, the level of T18 placental mosaicism may cause false negative NIPT result in this rare case of double aneuploidy.

    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.

    We report a 33 year-old woman addicted to chronic unspecified solvents abuse with stupor, respiratory disorders, tetraplegia and severe metabolic acidosis. On admission an unenhanced cranial CT scan showed symmetrical hypodensities of both lentiform nuclei. MR imaging performed 12 hours after stupor demonstrates bilateral putaminal hemorrhagic necrosis, bilateral external capsule, corona radiata and deep cerebellar hyperintensities with right cingulate cortex involvement. DWI reflected bilateral putaminal hyperintensities with restricted water diffusion as to citotoxic edema and development of vasogenic edema in the external capsule recalling a fork. On day twenty, after specific treatments MRI demonstrated a bilateral putaminal marginal enhancement. Bilateral putaminal necrosis is a characteristic but non-specific radiological finding of methanol poisoning. Lentiform Fork sign is a rare MRI finding reported in literature in 22 patients with various conditions characterized by metabolic acidosis. Vasogenic edema may be due to the differences in metabolic vulnerability between neurons and astrocytes. We postulate that metabolic acidosis could have an important role to generate this sign.

    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.

    Fibromatosis, also known as an extra-abdominal desmoid tumor, rarely occurs in the breast and is often mistaken for carcinoma, clinically and radiologically. Desmoid tumor is a monoclonal myofibroblastic neoplasm which is locally aggressive, but rarely metastasizes. We herein report a case of a 64-year-old woman who experienced two episodes of recurrence of mammary fibromatosis. The mass was initially detected by screening mammography. It appeared as an irregularly shaped mass which was confined within the mammary zone. Recurrences were excised from the right breast 10 and 17 months later. The second recurrence occurred in the subareolar area accompanied by skin thickening and showed an anechoic component on ultrasonography, which mimicked subareolar mastitis with an abscess.

    Propylthiouracil (PTU) is a drug that's used to manage hyperthyroidism and it can, on rare occasions, induce antineutrophil cytoplasmic antibody-associated vasculitis that involved multiple organ systems and it can also cause extremely rare isolated or diffuse pulmonary hemorrhage. We report here on a case of a patient who develop diffuse pulmonary hemorrhage after she had been taking PTU for five years. The patient is a 33-year-old woman who presented with hemoptysis. Simple chest radiographs and the chest CT showed bilateral ground-glass opacity, consolidation and pulmonary arterial hypertension. The bronchoalveolar lavage fluid revealed alveolar hemorrhage. The laboratory values showed increased perinuclear-antineutrophil cytoplasmic antibody ({rho} - ANCA) and anti-peroxidase antibody titers.

    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.)

    Blister formation and eccrine sweat gland necrosis is a cutaneous manifestation associated with states of impaired consciousness, most frequently reported after overdoses of central nervous system depressants, particularly phenobarbital. The case of a 45-year-old woman who developed "coma blisters" at six distinct anatomic sites after confirmed (laboratory) phenobarbital poisoning, associated with other central nervous system depressants (clonazepam, promethazine, oxcarbazepine and quetiapine), is presented. A biopsy from the left thumb blister taken on day 4 revealed focal necrosis of the epidermis and necrosis of sweat gland epithelial cells; direct immunofluorescence was strongly positive for IgG in superficial blood vessel walls but negative for IgM, IgA, C3 and C1q. The patient was discharged on day 21 with no sequelae.

    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.

    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.

    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.

    Sarcoidosis is a multisystem inflammatory disease characterized by the formation of noncaseating granulomas in various organs and tissues. The majority of patients with systemic sarcoidosis will present with lung and lymph node involvement. In addition, 20% have skin involvement that may be the only manifestation of the disease or may be an important prognostic marker for involvement of other organs. There are multiple forms of presentation of cutaneous sarcoidosis, which may be a true challenge.We report a patient with a one month history of an eruption of skin colored papules. Some were grouped in a symmetrical distribution on the trunk, inner arms, and lumbar region. Pathologic examination revealed an infiltrate in the papillary dermis showing a band of noncaseating granulomas along with disruption of the basal lamina and lichenoid changes. The clinicopathological correlation confirmed the diagnosis of lichenoid sarcoidosis. We consider our case interesting owing to the clinical presentation and the lichenoid distribution of granulomas.

    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.

  5. 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.

    We describe the distinctive brain CT and MRI findings seen in the putamen of three patients with hyperglycemia. 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)

    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.

    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.

    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.

    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.

    Epilepsy is a common neurological condition in dogs and cats. Although an increased likelihood of significant brain lesions with age has been identified in neurologically normal dogs with epileptic seizures, the underlying aetiology of epileptic seizures in cats that present with normal physical and neurological examinations remains unknown. In this cross-sectional study, the authors examined MRI findings in a large population of cats with a normal interictal physical and neurological examination. They hypothesised that age would have an impact on the prevalence of detectable lesions. First, following the guidelines for dogs and in accordance with previous studies, the authors divided the cats into three age groups (aged one year or younger, between one and six, and older than six) and calculated the proportion of cats with a detectable lesion on MRI in these groups. In the first group, 3/32 cats (9.4 per cent) had significant MRI abnormalities that were all consistent with congenital malformation; in the second group, only 5/92 (5.4 per cent) MRI scans were abnormal and in the third group, 15/ 65 (23.1 per cent) cats showed abnormal findings that were predominantly lesions of neoplastic origin. Second, to investigate the impact of age further, data were investigated as a continuous variable using receiver operating characteristic analysis. This indicated an optimal cut-off age of five years, above which MRI abnormalities were more likely, with an increase in the odds of a significant structural lesion increasing by 14 per cent per year.

    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. OBJETIVOS: Determinar a prevalência de sintomáticos respiratórios (RSI e casos

    We report our experience with the arthroscopic treatment of 23 cases of scaphoid nonunion. We explain the surgical technique and describe the different steps needed to achieve bone union. We report our initial clinical and radiological results. This was a prospective non-randomized study. Inclusion criteria were a scaphoid nonunion without radiocarpal arthritis, without any time limit and without any selection as to nonunion location. Before the operation, patients underwent an X-Ray and CT scan or MRI. Schernberg's classification was used to evaluate the location of the nonunion. Internal fixation was performed with a screw or K-wires. Bone grafts were taken from the dorsal side of the distal radius using a T-Lok™ bone marrow biopsy needle (Argon Medical Devices, Plano, TX, USA). A CT scan was performed 3 months after the operation to determine whether union was achieved. Pain, strength and range of motion were evaluated before and after the operation. The patients' smoking habits were also documented. The average follow-up was 17.3 months (4-41). There were 20 men and 3 women with an average age of 26 years (17-63). The average duration of nonunion before the operation was 17 months (6-60). Based on Schernberg's classification, there was one type I, 12 type II and 10 type III nonunions. Wrist strength increased from 32 to 41kg. Union was obtained in all patients after an average of 4 months (3-12). Numerous treatments have been described for treating scaphoid nonunion: Matti-Russe, Fisk-Fernadez bone graft, vascularized bone graft, bone substitutes, etc. The success rate varies depending on the technique and study design. We have described an arthroscopic technique for treating scaphoid nonunion with very promising preliminary results. Arthroscopic debridement is needed to ensure good quality bone at the graft site, while preserving extrinsic vascularization. Traction is used during the operation to restore the scaphoid height, once debridement has been

  15. The Problem of Finding the Maximal Multiple Flow in the Divisible Network and its Special Cases

    Full Text Available In the article the problem of finding the maximal multiple flow in the network of any natural multiplicity k is studied. 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.

    Toxoplasmosis is a ubiquitous protozoal infection that during pregnancy commonly affects the fetus severely, with maternal infection usually being mild self-limiting. Disseminated toxoplasmosis in a healthy pregnant woman has, to the best of our knowledge, not been reported before. We present a case of disseminated toxoplasmosis involving pulmonary, central nervous system, and lymph nodes in a pregnant woman and imaging findings on radiography, computed tomography, and magnetic resonance imaging.

    Clear-cell meningioma is a rare subtype of meningioma which occurs at a younger age and has a higher recurrence rate than other subtypes. We report two cases of clear-cell meningioma, one in the thoracolumbar spinal canal and the other in the cerebellopontine angle. Though the CT and MR imaging findings were not different from those of ordinary meningioma, after surgical removal the condition recurred repeatedly in the patient with spinal canal involvement.

    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.

  20. Narratives, memorable cases and metaphors of night nursing: findings from an interpretative phenomenological study.

    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.
