    The authors documented gross and microscopic morphology of lesions in corals on 7 islands spanning western, southern, and eastern Micronesia, sampling 76 colonies comprising 30 species of corals among 18 genera, with Acropora, Porites, and Montipora dominating. Tissue loss comprised the majority of gross lesions sampled (41%), followed by discoloration (30%) and growth anomaly (29%). Of 31 cases of tissue loss, most lesions were subacute (48%), followed by acute and chronic (26% each). Of 23 samples with discoloration, most were dark discoloration (40%), with bleaching and other discoloration each constituting 30%. Of 22 growth anomalies, umbonate growth anomalies composed half, with exophytic, nodular, and rugose growth anomalies composing the remainder. On histopathology, for 9 cases of dark discoloration, fungal infections predominated (77%); for 7 bleached corals, depletion of zooxanthellae from the gastrodermis made up a majority of microscopic diagnoses (57%); and for growth anomalies other than umbonate, hyperplasia of the basal body wall was the most common microscopic finding (63%). For the remainder of the gross lesions, no single microscopic finding constituted >50% of the total. Host response varied with the agent present on histology. Fragmentation of tissues was most often associated with algae (60%), whereas necrosis dominated (53%) for fungi. Two newly documented potentially symbiotic tissue-associated metazoans were seen in Porites and Montipora. Findings of multiple potential etiologies for a given gross lesion highlight the importance of incorporating histopathology in coral disease surveys. This study also expands the range of corals infected with cell-associated microbial aggregates.

    We report a case of acute disseminated encephalomyelitis (ADEM) with a residual cystic lesion on MRI. This seemed to be induced by Japanese encephalitis vaccination. Despite complete clinical improvement with high-dose steroid therapy, the cystic lesion has persisted for 3 years on MRI. There have been no previous reports of residual cystic lesions in ADEM.

    Full Text Available Paracoccidioidomycosis (PCM is a deep mycosis with primary lung manifestations that may present cutaneous and oral lesions. Oral lesions mimic other infectious diseases or even squamous cell carcinoma, clinically and microscopically. Sometimes, the dentist is the first to detect the disease, because lung lesions are asymptomatic, or even misdiagnosed. An unusual case of PCM with 5 months of evolution presenting pulmonary, oral, and cutaneous lesions that was diagnosed by the dentist based on oral lesions is presented and discussed.

    Natural leishmanial infections among feral mammals in the Republic of Panama were studied in relation to gross skin alterations. Three dermatotropic species of Leishmania, L. braziliensis, L. mexicana and L. hertigi, isolated from 230 sylvatic animals of 5 mammalian orders were involved. In 205 (89%) of the cases there were no gross skin alterations. Cryptic infections of all three leishmanial species among wild animals were confirmed by culture and hamster inoculation. This type of infection was always present in the sloths, Choloepus hoffmanni and Bradypus infusatcus, infected with L. braziliensis and in the porcupine, Coendou rothschildi, infected with L. hertigi. Suggestive skin alterations were encountered in 10 (4%) of infected animals. Only 15 (7%) of infected animals exhibited typical leishmanial lesions. It was possible to correlate skin depigmentation with the course of leishmanial infection in one animal, a young kinkajou, Potos flavus.

    We conducted gross and microscopic characterizations of lesions in Cnidaria from Palmyra Atoll, Central Pacific. We found growth anomalies (GA) to be the most commonly encountered lesion. Cases of discoloration and tissue loss were rare. GAs had a focal or multi-focal distribution and were predominantly nodular, exophytic, and umbonate. In scleractinians, the majority of GAs manifested as hyperplasia of the basal body wall (52% of cases), with an associated absence or reduction of polyp structure (mesenteries and filaments, actinopharynx and tentacles), and depletion of zooxanthellae in the gastrodermis of the upper body wall. In the soft corals Sinularia sp. and Lobophytum sp., GAs exclusively manifested as prominent hyperplasia of the coenenchyme with an increased density of solenia. In contrast to scleractinians, soft coral GAs displayed an inflammatory and necrotizing component with marked edema of the mesoglea, accompanied by infiltrates of variably-sized granular amoebocytes. Fungi, algae, sponges, and Crustacea were present in some scleractinian GAs, but absent in soft coral GAs. Fragmentation of tissues was a common finding in Acropora acuminata and Montipora cf. dilatata colonies with tissue loss, although no obvious causative agents were seen. Discoloration in the zoanthid, Palythoa tuberculosa, was found to be the result of necrosis, while in Lobophytum sp. discoloration was the result of zooxanthellar depletion (bleaching). Soft corals with discoloration or tissue loss showed a marked inflammatory response, however no obvious causative organisms were seen. Lesions that appeared similar at the gross level were revealed to be distinct by microscopy, emphasizing the importance of histopathology.

    Nineteen children, who had been admitted to the Pediatric Hospital of Coimbra with severe meningococcal infection with DIC, were submitted to clinical and radiological examination, an average of 4.2 years after hospitalization, in order to demonstrate late skeletal lesions. Patellar dystrophy, to our knowledge previously unreported, was found in 4 children, all of whom had overlying cutaneous scarring.

    Full Text Available Objective: To enhance the clinician's awareness of Strongyloidiasis as a cause of critical illness. Design: A case report. Setting: A 600- bed, tertiary care hospital in New Delhi, India. Patient: A 53 years old diabetic male, presenting with acute respiratory failure, having received treatment for 2 weeks for acute bronchitis that included corticosteroids. He had a history of receiving several courses of treatment for Strongyloides stercoralis larvae detected in his stools. During this admission, he went on to develop neurological signs, cutaneous lesions and acute respiratory distress syndrome (ARDS. Negative stool examinations led to the diagnosis being delayed until the 7th day, when the larvae were demonstrated in the skin lesions and tracheal aspirate. Conclusion: Awareness of the varied presentations of Strongyloidiasis and a diligent search for the larvae at various sites are crucial for early diagnosis.

    Coral reefs are threatened by a variety of factors including diseases that have caused significant damage in some regions such as in the Caribbean. At present, no data are available on coral diseases in the Mexican Pacific where Pocillopora spp. is a dominant component of coral communities. Here, we describe gross and microscopic morphology of lesions found in pocilloporids at four sites in the Mexican Pacific. Corals were identified and their lesions photographed and quantified in the field. Tissue samples were collected from healthy and affected colonies for histopathology. We recorded seven species of pocilloporids at the study sites with Isla Isabel being the location with the highest coral diversity (H′ = 1.27). Lesions were present in 42% of the colonies and included discoloration (32%), predation-induced tissue loss (30%), unexplained tissue loss (3%) and overgrowth by sponges or algae (35%). The most affected species, P. damicornis (50%), was also one of the most common in the region. No species was more prone to a particular lesion, but there was a significant association between location and the presence of lesions. Northern Islas Marietas (61%) and Isla Isabel (41%) had the highest prevalence of lesions, followed by Manzanillo (37%) and Bahías de Huatulco (23%). Histological changes included atrophy of the surface body wall with depletion of zooxanthellae (91%) in corals with discoloration (bleaching). Ablation of tissue from mesoglea (18%) was also observed. Colonies with unexplained tissue loss showed atrophy and thinning of the epidermis (89%), characterized by cuboidal instead of pseudocolumnar cells normally found in healthy pseudocolumnar ciliated epithelium. Bacterial aggregates between the mesoglea and gastrodermis (11%) were very conspicuous in healthy and diseased corals. Lesions produced by fish bites and gastropods were associated with tissue atrophy (40%) and, in some cases, algal overgrowth near the lesion (20%). No infectious agents

    A 59-year-old female patient, previously healthy, immunocompetent, presented left bulbar conjunctiva lesions and nodular-ulcerated lesions on the arms and cervical region, besides left cervical and retroauricular lymphadenopathy. She had previous contact with domestic cats that excoriated her face. The diagnosis was conclusive of disseminated sporotrichosis through clinical and epidemiological history and cultures of skin and ocular secretions. It evolved with good response to oral antifungal therapy. PMID:27579758

    Full Text Available Kaposi sarcoma (KS can present with a wide range of clinical features ranging from minimal cutaneous disease to a rapidly progressing neoplasm. Bone lesions are most often discovered accidently in the context of radiological investigations done for the screening of KS-visceral involvement [1]. Little is known on clinical outcome and response to antiretroviral therapy (ART and/or chemotherapy of these lytic osseous lesions. We report four cases with bone involvement in the context of systemic KS and aim at describing the long-term clinical outcome in two of these patients. Cases of AIDS-associated KS with disseminated bone lesions were collected in the HIV Unit, University Hospital Geneva, Switzerland. Patients were compared on clinical, biological and radiological features and therapeutic responses. Between 2002 and 2012, four HIV1-infected patients with T1 stage of KS presented disseminated osseous lesions (Table 1. Mean age was 43 years (range 39 - 47 years, mean time of follow up until our analysis was 48.5 months (SD 53.8, and mean CD4 count at KS diagnosis was 190.5 c/mL (SD 202.8. All patients showed hypodense bone lesions predominating the axial skeleton (figure 1, but no radiological imaging was performed to search for peripheral bone lesions.No patient reported pain or experienced pathological fractures. In one patient a dual-energy X-ray absorptiometry (DXA showed a bone mineral density within normal range after 10 years of KS diagnosis with disseminated bone lesions. No radiological change was observed in that patient despite stable KS disease after 13 cycles of liposomal doxorubicin and ART (figure 1. We describe a well-documented long-term follow up of disseminated osseous AIDS-associated KS disease. In our four cases, lytic bone lesions were asymptomatic and were not associated with bone fragility. We even could confirm the KS nature of the lesions by bone biopsy in patient B (3 months after KS diagnosis, as the differential

    Full Text Available Disseminated leishmaniasis (DL differs from other clinical forms of the disease due to the presence of many non-ulcerated lesions (papules and nodules in non-contiguous areas of the body. We describe the histopathology of DL non-ulcerated lesions and the presence of CD4-, CD20-, CD68-, CD31- and von Willebrand factor (vW-positive cells in the inflamed area. We analysed eighteen biopsies from non-ulcerated lesions and quantified the inflamed areas and the expression of CD4, CD20, CD68, CD31 and vW using Image-Pro software (Media Cybernetics. Diffuse lymphoplasmacytic perivascular infiltrates were found in dermal skin. Inflammation was observed in 3-73% of the total biopsy area and showed a significant linear correlation with the number of vW+ vessels. The most common cells were CD68+ macrophages, CD20+ B-cells and CD4+ T-cells. A significant linear correlation between CD4+ and CD20+ cells and the size of the inflamed area was also found. Our findings show chronic inflammation in all DL non-ulcerated lesions predominantly formed by macrophages, plasmacytes and T and B-cells. As the inflamed area expanded, the number of granulomas and extent of the vascular framework increased. Thus, we demonstrate that vessels may have an important role in the clinical evolution of DL lesions.

    Full Text Available Background. The outcome of neonates with congenital cutaneous Langerhans cell histiocytosis (LCH is variable. Observations. We report a case of LCH in a female premature neonate born at 33-week gestation. She had disseminated cutaneous lesions, which consisted of hemorrhagic papules and vesicles, with sparse healthy skin areas, and the hands and feet were contracted with scarring and blackened. She was in respiratory failure although no apparent pulmonary or bone lesions on X-rays were noted. Skin biopsy confirmed a diagnosis of LCH due to observation of CD1a+ Langerhans cells, which lacked expression of E-cadherin and CD56. The patient died 57 hours after birth. Conclusions. Based on this case and the literature survey, the outcome of premature babies with congenital cutaneous LCH lesions is noted to be unfavorable, with the majority of such cases suffering from multisystem disease.

    Full Text Available The objective of the study was to identify the species, gross and histopathological lesions of Eimeria in Japanese quails in Zaria. A total of 400 fresh faecal samples were collected and 10 quail birds were purchased from a quail farm. The faecal samples were processed using simple floatation technique. Oocysts shape indices of sporulated oocysts were determined. The intestines were observed for gross lesions and segments were analyzed using Giemsa stain and Haematoxylin and Eosin stain and then observed microscopically for the developmental stages of the parasite. Four species of Eimeria were identified in the study. Eimeria bateri of shape index of 1.36 conformed to the guidelines used while the other three Eimeria species with shape indices of 1.48, 1.03, and 1.40 were not confirmed. The main gross lesion seen was nonhaemorrhagic ballooning of the caeca. Intestinal scrapping smear revealed a developmental stage of the parasite (merozoites in the jejunum. Histopathology also revealed a developmental stage (schizont of the parasite in the caecum and desquamation of the epithelial lining with areas of necrosis. Further study is required using molecular techniques to properly identify the unknown species of Eimeria that were detected in the study.

    A 73-year-old man underwent {sup 18}F-fluorodeoxy-glucose positron emission tomography/computed tomography ({sup 18}F-FDG PET/CT) for the staging of colon cancer. The {sup 18}F-FDG PET/CT revealed three colonic lesions. The histopathologic examination of the postoperative gross specimen revealed a tubular adenoma, a tubulovillous adenoma and an adenocarcinoma. The maximal standardized uptake value (SU Vmax) of a tubulovillous adenoma was much higher than that of adenocarcinoma. This patient could be considered as a representative case highlighting that SU Vmax is not a reliable indicator for discriminating colon cancer from colonic adenomas.

    Disseminated histoplasmosis is caused by the dimorphic fungus Histoplasma capsulatum (H. capsulatum). The early clinical manifestations are nonspecific, often lead to diagnostic difficulty, and is misdiagnosed as tuberculosis and seen usually in immunosuppressed states. Fine needle aspiration cytology (FNAC) is a simple, safe, and quick technique to establish the initial diagnosis of H. capsulatum, thereby prompting early treatment. The skin involvement is rare in disseminated disease and we describe a case of disseminated histoplasmosis in an immunocompetent patient with unusual molluscum contagiosum like umbilicated skin lesions and FNAC of the cervical lymph node was the only tool for rapid and early confirmatory diagnosis.

    Fourteen cases with 18 grossly expansive lesions diagnosed over a period of 15 years as either "familial gigantiform cementoma" or "osseous dysplasia with jaw expansion" in an African population sample were reviewed. Eight lesions occurred in the anterior mandible, the maxilla was affected by four, three patients presented with more than one lesion and the most common associated pathologies were tooth displacement, conventional non expanding florid osseous dysplasia and simple bone cyst. No history of similar lesions in relatives of the diseased were recorded. The radiolucent fibrous component contained globular bone deposits and cellular osteoid with trabecular differentiation which matured into radiodense mineralized masses. Resorption of the cellular bone created cavities which are proposed to represent the early stage of simple bone cyst formation. It is recommended that "expansive osseous dysplasia" replace the out-dated term "familial gigantiform cementoma". The differential diagnoses of expansive osseous dysplasias are discussed.

    2011-03-05

    Abattoir data collected from three British pig health monitoring schemes were combined to investigate the associations between Salmonella infection and the presence of gross lesions detected in slaughtered pigs. Each set of results was linked back to the farm from which the pigs were submitted, and the Salmonella results and lesions reports were connected at farm level. Salmonella infection was determined through meat juice ELISA (MJE), and the health conditions were assessed by postmortem inspection. The final dataset contained 873 slapmarks, with an average of 215 samples tested by MJE, and 355 pigs that were assessed for health conditions, per slapmark. Each of the health assessment conditions was individually analysed by regression models to investigate associations with the MJE results, accounting for clustering at the slapmark level and also for seasonality. A multivariable model was also used to estimate the strength of association with MJE results when all the health conditions were entered into the model. The results showed positive associations between Salmonella and enzootic pneumonia-like lesions, milk spots, peritonitis and pericarditis.

    Histoplasmosis is well characterized as an endemic fungal disease restricted to certain areas of the USA. In Middle Europe, most patients present with acute pulmonary symptoms after travelling to endemic areas. Here, we want to illustrate the case of a 67-year-old man who presented with persistent oral ulcers, hoarseness, dysphagia, diarrhea, and weight loss to our Department of Otorhinolaryngology in December 2014. He was a retired construction worker and had a history of soil-disruptive activities in Africa and Middle and South America during employment. A positron emission tomography-computed tomography scan revealed prominent hypermetabolic lesions in the cecum and the lung, pointing towards a malignant disease. Surprisingly, histological examination of colonic and oral biopsies revealed abundant intracellular fungal elements, highly suspicious of Histoplasma capsulatum. Diagnosis was finally confirmed by panfungal polymerase chain reaction. Upon treatment with liposomal amphotericin followed by itraconazole, the severely ill patient showed an impressive clinical response. This case describes a disseminated manifestation of H. capsulatum years after the first exposure in an otherwise immunocompetent patient descending from a nonendemic area. PMID:27920657

    Fifty cranes, consisting of 46 sandhill (Grus canadensis) and four whooping cranes (Grus americana), were studied. Eighteen sandhill cranes and the four whooping cranes were naturally infected with disseminated visceral coccidiosis (DVC). The remaining sandhill cranes were chicks experimentally infected with oocysts of Eimeria reichenowi and/or E. gruis; five chicks served as controls. There were no clinical signs attributed to respiratory infection. Necropsy of naturally infected adult birds revealed nodules in many organs, including the lung, air sacs, trachea and nares. Artificially infected sandhill cranes and the whooping crane chicks that died from DVC had congestion and consolidated areas in the lung with frothy fluid in the airways. Grossly visible nodules were observed from 10 days postinoculation. Granulomatous pneumonia and tracheitis were observed with light microscopy. Lesions were associated with merogonic and gametogonic stages of eimerian coccidia. Granulomas and granulomatous foci contained parasitized large mononuclear cells. Merogonic stages were seen in lymphoid cells by ultrastructural examination. Oocysts were observed in the trachea and bronchial mucosa and admixed with exudate in the airways, indicating that crane eimerians can complete their life cycle at these sites. Of the few eimeriid coccidia that have extraintestinal stages of development in birds and mammals, only the species in cranes complete their life cycle in both the digestive and respiratory tracts.

    2002-05-01

    Chloroform extract of Prunus africana (Hook f. (Rosaceae) did not cause clinical signs or pathology in rats at daily oral doses of up to 1,000 mg/kg for 8 weeks. The extract caused marked clinical signs, organ damage and a 50% mortality rate at a dose of 3.3 g/kg for 6 days. The main lesions observed at this dose were marked centrilobular hepatocellular degeneration and necrosis, diffuse nephrosis, myocardial degeneration, lymphocytic necrosis and neuronal degeneration. The morphological damage in these tissues caused a corresponding rise in blood biochemical parameters namely, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, lactate dehydrogenase, creatine kinase and blood urea nitrogen. The target organs of toxicity of this extract are the liver, kidney and heart. Overt toxicity occurred only after the administration of multiple doses of 3.3 g/kg body weight. These findings confirm the suitability of this extract for therapeutic use, since the doses used in the therapy of prostate gland are much lower than those used in this study and would therefore not be expected to cause pathological changes.

    Histoplasmosis is caused by a dimorphic fungus Histoplasma capsulatum in endemic areas, mainly America, Africa, and Asia. In India, it is being reported from most states; however, it is endemic along the Ganges belt. We report a case of an apparently immunocompetent male who presented with 3-month history of fever, cough, and weight loss with recent onset odynophagia and had hepatosplenomegaly and mucocutaneous lesions over the face. The differential diagnosis of leishmaniasis, tuberculosis, leprosy, fungal infection, lymphoproliferative malignancy, and other granulomatous disorders was considered, but he succumbed to his illness. Antemortem skin biopsy and bone marrow aspiration along with postmortem liver, lung, and spleen biopsy showed disseminated histoplasmosis. This case highlights the need for an early suspicion of progressive disseminated histoplasmosis in the presence of classical mucocutaneous lesions even in an immunocompetent patient suffering from a febrile illness. Cure rate approaches almost 100% with early treatment, whereas it is universally fatal if left untreated. PMID:27752372

    Full Text Available We present a case of an immunocompetent 27-year-old African American man who was initially diagnosed with diffuse pulmonary coccidioidomycosis and started on oral fluconazole. While his symptoms improved, he began to develop tender cutaneous lesions. Biopsies of the cutaneous lesions grew Coccidioides immitis. Subsequent 18F-FDG PET/CT revealed extensive multisystem involvement including the skin/subcutaneous fat, lungs, spleen, lymph nodes, and skeleton. This case demonstrates the utility of obtaining an 18F-FDG PET/CT to assess the disease extent and activity in patients with disseminated coccidioidomycosis who initially present with symptoms involving only the lungs.

  4. A screen for suppressors of gross chromosomal rearrangements identifies a conserved role for PLP in preventing DNA lesions.

    Full Text Available Genome instability is a hallmark of cancer cells. One class of genome aberrations prevalent in tumor cells is termed gross chromosomal rearrangements (GCRs. GCRs comprise chromosome translocations, amplifications, inversions, deletion of whole chromosome arms, and interstitial deletions. Here, we report the results of a genome-wide screen in Saccharomyces cerevisiae aimed at identifying novel suppressors of GCR formation. The most potent novel GCR suppressor identified is BUD16, the gene coding for yeast pyridoxal kinase (Pdxk, a key enzyme in the metabolism of pyridoxal 5' phosphate (PLP, the biologically active form of vitamin B6. We show that Pdxk potently suppresses GCR events by curtailing the appearance of DNA lesions during the cell cycle. We also show that pharmacological inhibition of Pdxk in human cells leads to the production of DSBs and activation of the DNA damage checkpoint. Finally, our evidence suggests that PLP deficiency threatens genome integrity, most likely via its role in dTMP biosynthesis, as Pdxk-deficient cells accumulate uracil in their nuclear DNA and are sensitive to inhibition of ribonucleotide reductase. Since Pdxk links diet to genome stability, our work supports the hypothesis that dietary micronutrients reduce cancer risk by curtailing the accumulation of DNA damage and suggests that micronutrient depletion could be part of a defense mechanism against hyperproliferation.

    A case of acute disseminated encephalomyelitis (ADEM) was presented. The patient was a 4-year-old boy with convulsion, ataxic gait, facial palsy. It was postulated that the influenza vaccine might induce the disease in this case. Cranial CT showed a low density arease in the right temporal lobe, which disappeared afterwards when other low density areas appeared in the right cerebellar hemisphere and in inner portion of the body of the left lateral ventricle. All symptoms disappeared without therapy and the CT findings improved within three months after onset.

    The aim of the present work was, after a coccidiosis outbreak in a farm rearing red-legged partridges (Alectoris rufa) in Brittany (France), to identify the Eimeria species and describe gross lesions induced by three of them (Eimeria kofoidi, Eimeria caucasica and Eimeria legionensis) after experimental infection. E. kofoidi oocysts measured 19.3 µm × 16.3 µm on average; neither micropyle nor oocyst residuum were present, but one, two or more small polar granules were visible. After inoculation of 300,000 oocysts per partridge, severe gross lesions were observed in the duodenum and jejunum, characterized by thickened oedematous mucosa and lumen filled with thick mucus, gas and sometimes false-membrane due to sloughed epithelium. E. caucasica oocysts were on average 29.8 µm × 19.5 µm in size; no oocyst residuum was observed, but a large granule was well visible. E. caucasica also invaded both the duodenum and jejunum, causing haemorrhagic points on the serosal surface, as well as mucoid duodenitis and catarrhal enteritis when 30,000 oocysts were inoculated per bird. E. legionensis oocysts measured 22.6 µm × 14.9 µm on average; they presented a clear micropyle beneath which one or two granulations were present. E. legionensis mainly invaded the caeca; low mortality was observed at the dosage of 200,000 oocysts per bird. Caecal walls were thickened and caseous material was condensed into off-white cheesy cores. For each species, oocyst shedding started 5 days post inoculation, peaked at 9, 8 and 6 days post inoculation for E. kofoidi, E. caucasica and E. legionensis, respectively, then decreased and persisted until 15 days post inoculation (end of examinations).

    Full Text Available The study aimed at evaluation of pathological lesions on flexor surface of navicular bone and deep digital flexor tendon in horses graded in standard X-ray examination as 2 (fair. The evaluation was performed on fifteen horses (6-9 years of age. Analysis procedure involved examining navicular bones on X-ray pictures, post-slaughter preparation of navicular bones from the hoof capsule, macroscopic evaluation of fibrocartilage on flexor surface, and analysis of histologic preparations. In horses with navicular bones graded as 2, early pathological changes have already developed, even if such horses were not lame. The pathological changes included fibrillation and disruption of deep digital flexor tendon surface, loss of fibrocartillage in sagittal ridge area of navicular bone, thinning of subchondral bone on its flexor surface, and fibromyxoid changes in chondroid matrix. In terms of clinical relevance, more studies are needed to understand the sequence of changes in a better way.

    Herein we report a description of gross and microscopic lesions found in specific pathogen-free chicken embryos caused by UNAM-97 infectious bronchitis virus (IBV) variant strain after the eighth passage. Embryos were divided into three groups and were inoculated in the chorioallantoic sac with 0.2 mL of UNAM-97, Mass 41 IBV (positive control), or sterile PBS (negative control). Forty-eight hours later the allatoic fluid was taken and used to start a cycle of eight passages through 9-d-old embryos. Seven days after the last passage, embryos were harvested and macroscopic lesions in all organs were recorded. Proventriculus and gizzard samples were obtained from all embryos and routinely processed for microscopic and ultrastructural examinations. The UNAM-97 IBV variant strain caused two macroscopic lesions uncommon for Mexican strains: thin-walled proventriculus and gizzard, as well as urate accumulation within an extra-embryonic peritoneal sac, leaving the body through the umbilical duct and accompanied by the yolk sac. At microscopic level, two relevant findings were observed to be produced by this variant. In the proventriculus, there was a decrease in the gland papillary branching, while the gizzard showed a significant reduction in mucosa thickness and tubular-to-proliferative-cell ratio, as well as an absence of hyaline secretion in the lumen. Electrodense material scattered in proventricular and gizzard cells was observed, with a structure consistent with that of coronaviruses. These pathological chicken embryo findings have not been reported as being caused by other IBV strains in Mexico.

  12. Local inflammation, dissemination and coalescence of lesions are key for the progression towards active tuberculosis: the bubble model

    Directory of Open Access Journals (Sweden)

    2016-02-01

    Full Text Available The evolution of a tuberculosis (TB infection towards active disease is driven by a combination of factors mostly related to the host response. The equilibrium between control of the bacillary load and the pathology generated is crucial as regards preventing the growth and proliferation of TB lesions. In addition, some experimental evidence suggests an important role of both local endogenous reinfection and the coalescence of neighboring lesions.Herein we propose a mathematical model that captures the essence of these factors by defining three hypotheses: (i lesions grow logistically due to the inflammatory reaction; (ii new lesions can appear as a result of extracellular bacilli or infected macrophages that escape from older lesions; and (iii lesions can merge when they are close enough. This model was implemented in Matlab to simulate the dynamics of several lesions in a 3D space. It was also fitted to available microscopy data from infected C3HeB/FeJ mice, an animal model of active TB that reacts against Mycobacterium tuberculosis with an exaggerated inflammatory response.The results of the simulations show the dynamics observed experimentally, namely an initial increase in the number of lesions followed by oscillations, and an exponential increase in the mean area of the lesions. In addition, further analysis of experimental and simulation results show a strong coincidence of the area distributions of lesions at day 21, thereby highlighting the consistency of the model. Three simulation series removing each one of the hypothesis corroborate their essential role in the dynamics observed.These results demonstrate that three local factors, namely an exaggerated inflammatory response, an endogenous reinfection and a coalescence of lesions, are needed in order to progress towards active TB. The failure of one of these factors stops induction of the disease. This mathematical model may be used as a basis for developing strategies to stop the

    Clinical toxoplasmosis has been reported in many species of warm-blooded animals but is rare in camelids. Here we report acute fatal systemic toxoplasmosis involving heart, thyroid gland, stomach, intestine, diaphragm, kidneys, adrenal glands, and liver of a 13-mo-old llama (Llama glama). Many Toxoplasma gondii tachyzoites were associated with tissue necrosis in multiple organs. Death was attributed to severe myocarditis. Ulcers associated with numerous tachyzoites were present in the C3 compartment of the stomach. Tissue cyst development was followed using bradyzoite-specific T. gondii antibodies. Individual intracellular, and groups of 2 or more, bradyzoites were identified in hepatocytes, biliary epithelium, myocardiocytes, lung, diaphragm, thyroid gland, spleen, and stomach. Lesions in the brain were a few microglial nodules and very early tissue cysts containing 1-3 bradyzoites. These observations suggest that the animal had acquired toxoplasmosis recently. Diagnosis was confirmed immunohistochemically by reaction with T. gondii -specific polyclonal rabbit serum but not with antibodies to the related protozoan Neospora caninum . Genetic typing using the DNA extracted from paraffin-embedded myocardium of llama and 10 PCR-restriction fragment length polymorphism (RFLP) markers revealed a type II allele at the SAG1, SAG2, SAG3, BTUB, GRA6, c22-8, c29-2, PK1 L358, and Apico loci; therefore, this isolate belongs to the ToxoDB PCR-RFLP genotype #1, which is most common in North America and Europe.

    Benign spinal meningiomas have good prognoses, with low rates of recurrence and no cerebrospinal fluid (CSF) dissemination. However, we experienced an extremely rare case of initially benign non-dura-based spinal meningioma that showed multiple CSF disseminated lesions, which progressed for 14 years. A 29-year-old woman without neurofibromatosis presented with progressing dysesthesia in her lower limbs, low back pain, and intermittent claudication. Magnetic resonance imaging (MRI) showed an intradural extramedullary mass lesion at the Th10/11 level. The patient underwent a tumor resection. Intraoperative findings indicated that the tumor had no dural attachment. Histopathological diagnosis after gross total removal was microcystic meningioma (grade I, WHO 2007). Seven years after the first operation, other lesions appeared at the levels of Th11/12, L1, and L2/3 in MRI. These tumors were slow growing and became symptomatic; thus, a second surgery was performed 14 years after the first operation. The histopathological diagnosis was atypical meningioma (grade II, WHO 2007). Benign spinal meningiomas show CSF dissemination extremely rarely, although some authors have reported non-dura-based intraspinal clear-cell meningiomas showing CSF dissemination. However, even in cases of WHO grade I, neurosurgeons should pay attention to late CSF dissemination and malignant transformation after surgical removal of non-dura-based intraspinal meningiomas.

    Acute disseminated encephalomyelitis (ADEM) is an acute widespread autoimmune demyelinating condition, which principally affects the white matter of the brain and spinal cord. It usually follows an infection or vaccination. The typical presentation is that of multifocal neurologic disturbances accompanied by change in mental status. CSF analysis reveals lymphocytic pleocytosis and elevated protein content, but may also yield normal results. MRI is regarded as the diagnostic imaging modality of choice and typically demonstrates involvement of deep cerebral hemispheric and subcortical white matter as well as lesions in the basal ganglia, gray-white junction, diencephalon, brainstem, cerebellum and spinal cord. Unlike multiple sclerosis (MS), ADEM has a monophasic course and a favorable long-term prognosis. (orig.) [German] Die akute disseminierte Enzephalomyelitis (ADEM) ist eine akut auftretende autoimmune demylinisierende Erkrankung der weissen Substanz, die hauptsaechlich Gehirn und Rueckenmark befaellt. Ueblicherweise tritt sie nach einer Infektion oder Impfung auf. Die Entwicklung einer fokalen oder multifokalen neurologischen Funktionsstoerung ist das Kennzeichen der klinischen Praesentation der ADEM. Lymphozytaere Pleozytose und Eiweisserhoehung sind typische Befunde in der Liquoruntersuchung. Die Magnetresonanztomographie (MRT) ist die Untersuchungsmethode der Wahl. Die ADEM-Laesionen sind typischerweise gross, multipel und asymmetrisch. Sie koennen in den Gross- und Kleinhirnhemisphaeren, im Hirnstamm und im Rueckenmark lokalisiert sein. Die subkortikale und die zentrale weisse Substanz sind am haeufigsten befallen. Weniger haeufig ist die graue Substanz der Thalami und der Basalganglien betroffen. Im Gegensatz zur Multiplen Sklerose (MS) ist die Prognose der ADEM im Allgemeinen guenstig. (orig.)

    . Ultrasonographic examinations were performed before and after biopsy. Orchiectomy was carried out on day 100 and the testicles were examined for gross and microscopic lesions. Ultrasonography permitted to map testicular alterations and to follow the evolution of the lesions. Small areas of calcification were observed in 55 and 70% of testicles from groups 2 and 3, respectively. Testicular biopsy with Tru-Cut needle provided enough material for histology but induced small and focal areas of testicular lesions close to the biopsy site. In spite of the potential occurrence of calcification and other minimal lesions, it was shown that testicular biopsy with Tru-Cut needle in rams is safe because did not significantly compromise the functional and structural testicular characteristics.

    A 2-year-old intact female miniature Pinscher weighing 1.7 kg with a body condition score of 2/5 was presented for acute vomiting, lethargy for 2 days, and large petechial skin lesions on the hip region including the tail. Acute pancreatitis was diagnosed by clinical signs, strong positive cPLI test, laboratory test and ultrasound appearance. While the clinical signs associated with acute pancreatitis had improved in 3-5 days, lesion of petechial appeared on the left hip region 7 days after the presentation, with a fast progression into a necrotic tissue along the left side hip. Allogenic platelet rich plasma (PRP) with Weibrich and Kleis method was administered to promote skin healing and regeneration. Gradual and complete improvement in the dog's wound lesions was noted approximately 1 month after applying allogeneic topical PRP. In this case report, allogeneic PRP was applied to a large regional cutaneous defect caused by coagulopathy induced by acute pancreatitis. Topical application of PRP in this case was unique in that allogeneic PRP was used instead of autologous PRP for the first time in cutaneous soft-tissue wound management in the veterinary medical field.

    osteolytic lesions. DESCRIPTION: A 6-year-old boy was admitted with a one-month history of fever and hepatosplenomegaly. On admission, he looked sick, pale, and had disseminated lymphadenopathy and hepatosplenomegaly. The laboratory findings included anemia (hemoglobin = 6.8 g/dl, eosinophilia (1,222/mm³, thrombocytopenia (102,000/mm³, and hypoalbuminemia (serum albumin = 2.2 g/dl. Paracoccidioides brasiliensis was identified in bone marrow examination. In the second week after admission, the patient presented joint pain, poor activity and difficulty in walking. He presented hypercalcemia (maximum value = 14.9 mg% and reduction in renal function, which lasted for two weeks. On the 42nd day after admission, his chest X-ray showed lytic lesions in clavicle, scapula, ribs, and humerus, with bilateral slipped capital humeral epiphysis. The patient presented nephrocalcinosis and nephrolithiasis, reduction in creatinine clearance and evidence of tubular lesions. At the end of the second month after admission, Mycobacterium tuberculosis was isolated in gastric lavage. The child received treatment for paracoccidioidomycosis and tuberculosis and has not had any sequelae for 3 years. COMMENTS: The development of symptomatic hypercalcemia leading to renal lesion, associated with multiple osteolytic lesions, had never been described in paracoccidioidomycosis. Although pulmonary tuberculosis was diagnosed and could be related to hypercalcemia, the sudden onset of hypercalcemia and its normalization without specific treatment for tuberculosis suggests that bone lysis was the most important factor in the genesis of hypercalcemia.

    Full Text Available Ankylosing spondylitis is a chronic inflammatory disorder affecting mainly the axial skeleton. Here we report a case of a man with a clinical suspicion of ankylosing spondylitis but with a persistence of increased inflammatory markers. In this case, 18F-FDG-PET/CT revealed multiple hypermetabolic lesions in axial skeleton, lymph nodes, and the lung, suggestive of either disseminated tuberculosis or lymphoma. Histological analysis of the pulmonary lesion revealed mycobacterium tuberculosis. This case highlights, firstly, the importance of excluding other diagnoses in the presence of clinical picture of ankylosing spondylitis and high inflammatory markers and, secondly, the determining role of PET/CT.

    The cause of the death of a 16-month-old Brasileiro-de-Hipismo filly and a 3-year-old male Paint Horse with clinical manifestations of anemia and apathy from southern Brazil was investigated. These horses were maintained at the same stable; received hay as part of their diet and were submitted for routine necropsy evaluations. Significant gross findings included several nodules randomly distributed throughout the pulmonary lobes of both horses, and the kidneys, myocardium, and the frontal lobes of the cerebrum of the filly. Histopathological evaluation revealed pyogranulomatous bronchopneumonia in both horses; granulomatous interstitial nephritis, myocarditis, and encephalitis were observed in the filly. All lesions contained vasculitis and thrombosis associated with myriads of intralesional, branching, septate fungi consistent with Aspergillus spp.; intralesional fungi were more easily identified by the Grocott methenamine silver stain. Mycological culture of fresh pulmonary sections from both horses and the brain of the filly revealed pure growths of A. fumigatus. These findings confirmed the participation of A. fumigatus in the etiopathogenesis of the lesions observed in the lungs of both horses, and the cerebrum, myocardium and kidneys of the filly and might represent the first description of A. fumigatus-induced encephalitis in horses. Additionally, we believe that infection occurred during the ingestion of contaminated hay or by inhalation of spores within contaminated bedding that resulted in transient nasal mycosis, which progressed to pyogranulomatous bronchopneumonia in both horses with embolic encephalitic, myocardial, and renal dissemination of A. fumigatus occurring only in the filly.

    Full Text Available Acute disseminated histoplasmosis is a frequent condition in HIV carriers. Thirty-five cases of endocarditis caused by Histoplasma capsulatum have been reported in international literature, and all these descriptions correspond to a context of subacute disseminated histoplasmosis. This paper presents the case of a HIV-positive patient with fever, dyspnea, weight loss, vomiting and polyadenopathies to whom histoplasmosis was diagnosed following blood-cultures and isolation of the agent responsible for cutaneous lesions, and in whom aortic-valve vegetations were found during an echocardiogram. The patient was treated with amphotericin B and had a good outcome; subsequent echocardiograms showed no vegetations. Literature on the subject is reviewed, with special emphasis on diagnosis and treatment of previously described cases.

    Histoplasmosis is a systemic fungal disease that may present in a variety of clinical manifestations. Involvment of the oral mucosa is very rare and may occur as part of disseminated histoplasmosis or as isolated involvement. We present a patient with disseminated histoplasmosis, in whom oral lesions were the initial manifestation of the disease.

    This paper extends the work of Dunne, Roberts, and Samuelson [3] and Davis, Haltiwanger, and Schuh [2] on gross job flows among manufacturing plants. Gross job creation, destruction, and reallocation have been shown to be important in understanding the birth, growth, and death of plants, and the relation of plant life cycles to the business cycle. However, little is known about job flows between firms or how job flows among plants occur within firms (corporate restructuring). We use informati...

  20. Cutaneous Cryptococcosis: a marker of life threatening disseminated cryptococcosis in HIV AIDS

    Full Text Available Cryptococcosis is an opportunistic infection caused by a ubiquitous encapsulated yeast, Cryptococcus neoformans. Affects 5 – 10 % of patients with HIV worldwide. Disseminated cryptococcosis is one of the AIDS defining criteria and the most common cause of life threatening meningitis. Upto 20% of patients with disseminated disease can have skin involvement. Cutaneous lesions in disseminated cryptococcosis are seldom pathognomonic and portent neurological involvement. The significance of skin lesions may provide the first evidence of dissemination and indicate a poor prognosis, however, earlier recognition and treatment would improve survival. Herein we report a case of cryptococcal meningitis with skin lesions in a HIV seropositive patient.

    We report a unique case of botryoid Wilms' tumor with its characteristic imaging findings in a 5-month-old boy presenting with gross hematuria. In our case, ultrasonography revealed lobulated hyperechoic lesions filling the pelvicalyceal system without parenchymal invasion, mimicking a blood clot. However, magnetic resonance imaging (MRI) demonstrated the exact extent of the lesion with diffusion restriction and delayed enhancement suggestive of a tumor. Despite their rarity, botryoid Wilms' tumors should be included in the differential diagnosis of lobulated renal pelvic lesions presenting as gross hematuria in children, and MRI can suggest the diagnosis.

    2007-09-01

    A juvenile cheetah (Acinonyx jubatus) died with rapidly progressive pyrexia, tachypnea, abdominal effusion, and hepatomegaly. Postmortem examination revealed lesions consistent with acute disseminated infection with Toxoplasma gondii. The presence of this organism was confirmed in multiple organs by immunohistochemistry and polymerase chain reaction. To the best of our knowledge, we propose this to be the first reported case of primary acute disseminated toxoplasmosis in a cheetah.

    A malignant neoplasm in the central nervous system with diffuse white matter changes on magnetic resonance imaging (MRI) is rare in children. It could be misdiagnosed as acute disseminated encephalomyelitis. This report presents our experience based on 4 patients (3 male, 1 female; aged 7-13 years) whose MRI showed diffuse lesions in white matter and who were initially diagnosed with acute disseminated encephalomyelitis. All of the patients received corticosteroid therapy. After brain biopsy, the patients were diagnosed with gliomatosis cerebri, primitive neuroectodermal tumor and central nervous system lymphoma. We also provide literature reviews and discuss the differentiation of central nervous system neoplasm from acute disseminated encephalomyelitis.

    Cryptococcosis is a fungal infection of opportunistic behavior that is unusual in immunocompetent patients. We report a rare case of disseminated cryptococcosis with cutaneous involvement in an immunocompetent individual. During hospitalization, Cryptococcus gattii was isolated from skin lesions, lung and spinal fluid. The diagnosis of disseminated cryptococcosis was confirmed and treatment was established. The patient showed improvement. Due to the probable clinical severity of the disease and the possibility that skin lesions may be the first manifestation of this illness, prompt diagnosis must be established and treatment provided.

    Information security involves many branches of effort, including information assurance, host level security, physical security, and network security. Computer network security methods and implementations are given a top-down description to permit a medically focused audience to anchor this information to their daily practice. The depth of detail of network functionality and security measures, like that of the study of human anatomy, can be highly involved. Presented at the level of major gross anatomical systems, this paper will focus on network backbone implementation and perimeter defenses, then diagnostic tools, and finally the user practices (the human element). Physical security measures, though significant, have been defined as beyond the scope of this presentation.

    Work, Thierry M.; Aeby, Greta S.; Lasne, Gregory; Tribollet, Aline

    2014-01-01

    We surveyed the reefs of Grande Terre, New Caledonia, for coral diseases in 2010 and 2013. Lesions encountered in hard and soft corals were systematically described at the gross and microscopic level. We sampled paired and normal tissues from 101 and 65 colonies in 2010 and 2013, respectively, comprising 51 species of corals from 27 genera. Tissue loss was the most common gross lesion sampled (40%) followed by discoloration (28%), growth anomalies (13%), bleaching (10%), and flatworm infestation (1%). When grouped by gross lesions, the diversity of microscopic lesions as measured by Shannon–Wiener index was highest for tissue loss, followed by discoloration, bleaching, and growth anomaly. Our findings document an extension of the range of certain diseases such as Porites trematodiasis and endolithic hypermycosis (dark spots) to the Western Pacific as well as the presence of a putative cnidarian endosymbiont. We also expand the range of species infected by cell-associated microbial aggregates, and confirm the trend that these aggregates predominate in dominant genera of corals in the Indo-Pacific. This study highlights the importance of including histopathology as an integral component of baseline coral disease surveys, because a given gross lesion might be associated with multiple potential causative agents.

    Lupus vulgaris is a secondary form of cutaneous tuberculosis which persists for years if not treated. The head and neck are the most commonly affected sites. While less frequently arms and legs, and rarely the trunk and the scalp are involved. Herein, we describe a 73-year-old man with a 5-year history of slowly growing, atrophic, some eroded and ulcerated, red-brown plaques on his forehead, nose, cheeks, ear lobes, trunk and extremites. All of his disseminated lesions healed after antituberculosis therapy.

    Full Text Available We report a rare case of disseminated coccidioidomycosis with multifocal musculoskeletal involvement. The patient presented to the emergency department with left shoulder pain and swelling. Magnetic resonance imaging of the left shoulder revealed enhancing soft tissue masses, bony lesions, and fluid collections in and around the glenohumeral joint with involvement of the proximal humerus, glenoid, and rotator cuff musculature. Multiple additional areas of involvement were subsequently discovered. Fungal cultures confirmed coccidioidomycosis infection at all surgical sites with superimposed polymicrobial bacterial infection in the left shoulder.

    Disseminated gonococcal infection (DGI) is a rare complication of primary infection with Neisseria gonorrhoeae. Cardiac involvement in this condition is rare, and is usually limited to endocarditis. However, there are a number of older reports suggestive of direct myocardial involvement. We report a case of a 38-year-old male with HIV who presented with chest pain, pharyngitis, tenosynovitis, and purpuric skin lesions. Transthoracic echocardiogram showed acute biventricular dysfunction. Skin biopsy showed diplococci consistent with disseminated gonococcal infection, and treatment with ceftriaxone improved his symptoms and ejection fraction. Though gonococcal infection was never proven with culture or nucleic acid amplification testing, the clinical picture and histologic findings were highly suggestive of DGI. Clinicians should consider disseminated gonococcal infection when a patient presents with acute myocarditis, especially if there are concurrent skin and joint lesions. PMID:26246922

    The paper presents the results of radiological investigations of food products sampled in the summer and fall of 2011 and 2012 in different parts of Van, Turkey. Gross radioactivity measurements in food products were evaluated. Food items were divided into eight groups: (1) water, (2) fish, (3) cheese products, (4) fruits, (5) vegetables, (6) herbs, (7) walnut and (8) rock salt. The levels of the gross alpha and gross beta radioactivity in all food samples varied widely ranging from 0.070 to 10.885 Bq/g and from 0.132 to 48.285 Bq/g on dry mass basis, respectively. In one sample, gross alpha and gross beta activity concentrations were found to be relatively high according to the other samples and in all samples, the gross alpha radioactivity was measured lower than the gross beta radioactivity. The gross α and gross β activities were measured by using α/β counter of the multi-detector low background system (PIC MPC-9604).

    2014-01-01

    With technological advancements and wider availability of multimodality imaging, incidental lesions are frequently identified in patients undergoing various imaging studies. We report here a case of multiloculated disseminated perineural or Tarlov cysts (TCs). The primary aim of our study was to (1) provide a comprehensive review of the clinical, imaging and histopathological features of TCs (2) to draw attention to the fact that multiple lumbo-sacral and dorsal TCs can produce nerve injuries and serious movement disturbances (3) to document the usefulness of the magnetic resonance imaging (MRI) and bone scan in noninvasive diagnosis and guiding management in such cases. These cysts are clearly identified by MR and computerized tomography imaging of the lumbosacral spine. However, there are no reports on the scintigraphic findings of TCs in literature. TCs are typically benign, asymptomatic lesions that can simply be monitored. Until date, no consensus exists about the best surgical strategy to be followed for their management.

    Disseminated visceral coccidiosis (DVC) caused by Eimeria spp was first recognized as a disease entity in captive sandhill cranes (Grus canadensis) and whooping cranes (G americana) at the Patuxent Wildlife Research Center. Because cranes produced at the Center are reintroduced to the wild to augment wild populations, studies involving both experimentally induced and natural infections were initiated to determine the potential or actual occurrence of DVC in wild Gruidae. Nine sandhill cranes dosed orally with eimerian oocysts of wild origin developed lesions characteristic of DVC. Extraintestinal granulomas associated with developing schizonts were found in 6 birds. Similar lesions were observed in wild sandhill cranes throughout parts of midwestern United States, Alaska, and Saskatchewan. These studies revealed the wide geographic distribution and the high frequency of occurrence of DVC in wild cranes.

    Full Text Available Abstract Background Disseminated Intravascular Coagulation (DIC complicates up to 7% of malignancies, the commonest solid organ association being adenocarcinoma. Transitional Cell Carcinoma (TCC has rarely been associated with DIC. Case presentation A 74-year-old woman with TCC bladder and DIC was found to have a cardiac lesion suspicious for metastatic disease. The DIC improved with infusion of plasma and administration of Vitamin K, however the cardiac lesion was deemed inoperable and chemotherapy inappropriate; given the patients functional status. We postulate that direct activation of the coagulation cascade by the intraventricular metastasis probably triggered the coagulopathy in this patient. Conclusion Cardiac metastases should be considered in cancer patients with otherwise unexplained DIC. This may influence treatment choices.

    A case of generalized granuloma annulare in a 55 year old man is reported. The disease appeared five years before the first admission to the hospital. A large number of bluish-red or skin-colour papules were scattered mainly around the earlobes, buttocks and on the extremities. Some of the lesions were lined up in rings or plaques. Small depigmented and brownish scars were present. Two biopsies revealed characteristic foci of complete collagen degeneration accompanied by a palisading infiltrate in the upper dermis. Treatment with tuberculostatics and antimalarics was without improvement. The lesions cleared after a course of prednison, but reappeared when the drug was discontinued.

    Full Text Available Introduction. Delusional infestation is a rare monosymptomatic hypochondriacal psychosis according to The Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013. It can be a primary disorder or associated with an underlying psychological or physical disorder. It commonly presents as delusional parasitosis, and less than 1% may be fungi related. We present this case as it is a rare presentation of a rare condition. Case Presentation. Our patient is a 60-year-old Caucasian man who presented with a 7-year history of delusional infestation manifested as a disseminated fungal infection. He had previously been reviewed by multiple physicians for the same with no systemic illness diagnosed. After multiple reviews and thorough investigation we diagnosed him with a likely delusional disorder. As is common with this patient cohort he refused psychiatric review or antipsychotic medication. Conclusion. A delusion of a disseminated fungal infestation is a rare condition. It is exceedingly difficult to treat as these patients often refuse to believe the investigation results and diagnosis. Furthermore, they either refuse or are noncompliant with treatment. Multidisciplinary outpatient evaluation may be the best way to allay patient fears and improve treatment compliance.

    2014-10-01

    Full Text Available Introduction Acute disseminated encephalomyelitis (ADEM is an acute inflammatory and demyelinating disease of the central nervous system, resulting in various neurological symptoms. Usually, the disease appears following vaccination or systemic viral infections. In rare cases, the disease appears following pneumococcal infections. Case Presentation The patient was a 27 year-old man who was referred to the clinic following a few days of fever and cold with consciousness deficit and right hemiplegia. Based on the analysis of cerebrospinal fluid (CSF and diagnosis of pneumococcal meningitis, he received suitable antibiotic treatment. Despite complete return of consciousness, good general condition, and negative smear and culture of CSF, fever continued and no considerable improvement was observed in the hemiplegia. Therefore, brain magnetic resonance imaging (MRI was performed and according to the findings, treatment was started with the diagnosis of acute disseminated encephalomyelitis. Treatment with prednisolone at first obviated the fever and after a month brought about a complete hemiplegia cure. Following the status of the patient after three months, his MRI clearly showed considerable reduction in lesions. Discussion There is possible occurrence of ADEM following pneumococcal meningitis. Regarding the occurrence of neurological symptoms such as visual disturbance, hemiparesis or hemiplegia following bacterial meningitis, ADEM can be considered as one of the differential diagnoses to be accompanied by MRI. Acute disseminated encephalomyelitis should be treated using suitable dose of corticosteroids.

    Nocardiosis is a rare bacterial infection occurring mainly in patients with deficient cell-mediated immunity. Although disseminated nocardiosis after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a rare complication, it is associated with high mortality. Moreover, after allo-HSCT, nocardiosis may be mistaken for other bacterial or fungal infections because clinical and radiographic findings of pulmonary, cerebral, and cutaneous nocardiosis lesions are non-specific. Here, we report a case of disseminated nocardiosis (caused by Nocardia abscessus) with skin, pulmonary, liver, lymph node, and multiple brain abscesses in a patient after allo-HSCT. The patient initially responded clinically and radiographically to imipenem/cilastin and trimethoprim-sulfamethoxazole therapy. Clinicians should be aware of the possibility of nocardiosis in allo-HSCT recipients who are treated with multiple immunosuppressive agents to control chronic graft-versus-host disease. Accurate diagnosis and identification of disseminated nocardiosis is important to ensure administration of the correct antibiotic regimen. © 2016 John Wiley & Sons A/S.

    Full Text Available Happiness is rising on the political agenda and this calls for measures of how well nations perform in creating great happiness for a great number, analogous to measures of success in creating wealth, such as GDP. Happiness is defined as subjective enjoyment of one’s life as-a-whole and this can be measured using self-reports. Question on happiness are currently used in large scale surveys of the general population in nations. As a result we have now comparable data on happiness in 144 contemporary nations and time-series of 25 years and longer on 11 developed nations. These data can be aggregated in different ways: If the aim is simply greater happiness for a greater number of citizens, Average happiness (AH is an appropriate measure. If the focus is on enduring happiness, it is better to combine average happiness with longevity in an index of Happy Life Years (HLY. If the aim is to reduce disparity among citizens a relevant indicator is the Inequality of Happiness (IH in the nations as measured with the standard deviation. Average and dispersion can also be combined in an index of Inequality-Adjusted Happiness (IAH. Comparison across nations shows sizable differences on all these measures of gross national happiness and these differences correspond with societal characteristics that can be influenced by policy makers, such as freedom and justice. Comparison over time shows major improvement during the last decade.

  14. The Mechanics of Gross Moist Stability

    Directory of Open Access Journals (Sweden)

    Zeljka Fuchs

    2009-08-01

    Full Text Available The gross moist stability relates the net lateral outflow of moist entropy or moist static energy from an atmospheric convective region to some measure of the strength of the convection in that region. If the gross moist stability can be predicted as a function of the local environmental conditions, then it becomes the key element in understanding how convection is controlled by the large-scale flow. This paper provides a guide to the various ways in which the gross moist stability is defined and the subtleties of its calculation from observations and models. Various theories for the determination of the gross moist stability are presented and its roles in current conceptual models for the tropical atmospheric circulation are analyzed. The possible effect of negative gross moist stability on the development and dynamics of tropical disturbances is currently of great interest.

    We report the first case of an occurrence of multiphasic acute disseminated encephalomyelitis (ADEM) associated with atypical rubella virus infection with no rash and long-term increased titers of serum anti-rubella IgM in a 17-year-old male who had no history of rubella vaccination. He suffered from at least six clinical exacerbations with disseminated hyperintense lesions on FLAIR MR images during the course of 18 months. Repeated methylprednisolone pulse therapy and intravenous immunoglobulin therapy resolved the exacerbations. In patients with multiphasic ADEM of unknown etiology, clinicians should also consider the possibility of preceding infection with rubella virus.

    A 28-year-old woman presented with reddish raised, shiny lesions over the face and ears present for the past 3 years. Four years ago, she developed in her left axilla a nodule that became fluctuant and tender, which ruptured to discharge seropurulent material. It subsided after the patient had received antibiotics for 6 months, leaving puckered scarring. There was no history of antituberculous treatment. After 1 year, she developed papulonodular lesions on her face, nose, and ears. There was now a history of malaise, fever, dry cough, and anorexia and weight loss for the past 2 months. The patient was fully vaccinated in childhood, including against varicella infection. The general physical examination revealed lymphadenopathy involving cervical, axillary, and inguinal lymph nodes 0.5 x 0.5 cm to 1 x 1.5 cm, firm in consistency, and nontender. They were discrete except in the left axilla where multiple matted lymph nodes were present with overlying scarring and a papule. Her systemic examination was normal. Cutaneous examination showed a shiny erythematous plaque 3x2 cm with central atrophy and scarring on the face (Figure). It was comprised of multiple shiny nontender soft papules arranged in annular configuration. Similar discrete papules and nodules with adherent fine scaling were seen bilaterally on the alar prominence of the nose, lower lip, and post-auricular area. On diascopy, apple jelly nodules were seen. The hemogram, liver function tests, and renal function tests were normal, except for an elevated erythrocyte sedimentation rate. The Mantoux test showed erythema and an induration of 20 x 20 cm. A posteroanterior view on the chest x-ray showed fibrotic changes suggestive of pulmonary tuberculosis. Ultrasonography of the abdomen and pelvis showed no tubercular foci. Human immunodeficiency virus serology by enzyme-linked immunosorbent assay with 3 different kits was nonreactive. Histopathology from a nodule showed a focally thinned-out epidermis with

    Full Text Available The term performativity and its inflexions have been applied to several concepts in the field of educational research. In this study, we trace the dissemination of the word performativity and its correlates, starting from the meanings attributed to the term by Stephen Ball, in his analysis of contemporary educational policies, but also using the theories of Jacques Derrida and Judith Butler, who used these terms to refer to social processes of signification and identification, and also references made to the term in studies of Anthropology, Arts, Political Science, Linguistics, Philosophy and Physics. On top of that, we researched studies in the field of academic education, examining articles from journals and other periodicals published over the last five years, in order to discuss the various meanings attributed to the term within the educational field. We present, in this paper, a synthesis of our investigations, highlighting the affirmations, negations and truth effects that can be construed from the use of these terms in educational research, in particular when approaching current educational policies.

  20. The future of gross anatomy teaching.

    Science.gov (United States)

    Malamed, S; Seiden, D

    1995-01-01

    A survey of U.S. departments of anatomy, physiology, and biochemistry shows that 39% of the respondent anatomy departments reported declines in the numbers of graduate students taking the human gross anatomy course. Similarly, 42% of the departments reported decreases in the numbers of graduate students teaching human gross anatomy. These decreases were greater in anatomy than in physiology and in biochemistry. The percentages of departments reporting increases in students taking or teaching their courses was 6% for human gross anatomy and 0% to 19% for physiology and biochemistry courses. To reverse this trend the establishment of specific programs for the training of gross anatomy teachers is advocated. These new teachers will be available as the need for them is increasingly recognized in the future.

  1. FUZZY ECCENTRICITY AND GROSS ERROR IDENTIFICATION

    2006-01-01

    The dominant and recessive effect made by exceptional interferer is analyzed in measurement system based on responsive character, and the gross error model of fuzzy clustering based on fuzzy relation and fuzzy equipollence relation is built. The concept and calculate formula of fuzzy eccentricity are defined to deduce the evaluation rule and function of gross error, on the base of them, a fuzzy clustering method of separating and discriminating the gross error is found. Utilized in the dynamic circular division measurement system, the method can identify and eliminate gross error in measured data, and reduce measured data dispersity. Experimental results indicate that the use of the method and model enables repetitive precision of the system to improve 80% higher than the foregoing system, to reach 3.5 s, and angle measurement error is less than 7 s.

    Full Text Available Acute disseminated encephalomyelitis (ADEM is a disease that is characterized by an immune-mediated inflammatory reaction and demyelination in the central nervous system, including optic nerve, brain and spinal cord, which is common in children, but also appears in adults. ADEM happens probably with a causative relationship to viral diseases or prior vaccinations. It can also occur without any cause. The clinical symptoms of ADEM can begin with fever, headache and meningeal signs, followed by abnormal mental status, seizures and focal neurological signs, such as limb pareses, visual decline and speech disturbances. And their clinical courses may be monophasic, recurrent or multiphasic, mild but also very aggressive. Neuroimaging may be characterized by large demyelinating lesions in the brain involving both the white and the grey matter, and spinal cord. Lesions in ADEM are typically large globular lesions, multiple, and asymmetric, partially with diffuse or ring-like gadolinium enhancement. The diagnosis of ADEM requires both multifocal involvement and encephalopathy by consensus criteria. The differential diagnoses of ADEM include a variety of disorders, such as viral encephalitis, multiple sclerosis, neuromyelitis optica spectrum disorders and primary central nervous system vasculitis, etc. Treatments of ADEM include corticosteroids, intravenous immunoglobulin, plasmapheresis and other immunosuppressive agents.

Clinical assessment scores for 38 girls and women with Rett syndrome who attended the Danish Center for Rett Syndrome were used to assess consistency of measurement. Principal components analysis enabled the calculation of three factor scores: Sitting, Standing and Walking, and Challenge. Motor scores were poorer with increasing age and those with the p.Arg133Cys, p.Arg294* or p.Arg306Cys mutation achieved higher scores than those with a large deletion. The repeatability of clinical assessment was excellent (intraclass correlation coefficient for total score 0.99, 95% CI 0.93-0.98). The standard error of measurement for the total score was 2 points and we would be 95% confident that a change 4 points in the 45-point scale would be greater than within-subject measurement error. The Rett Syndrome Gross Motor Scale could be an appropriate measure of gross motor skills in clinical practice and clinical trials.

    With technological advancements and wider availability of multimodality imaging, incidental lesions are frequently identified in patients undergoing various imaging studies. We report here a case of multiloculated disseminated perineural or Tarlov cysts (TCs). The primary aim of this case study was to (1) provide a comprehensive review of the clinical, imaging, and histopathological features of TCs (2) to draw attention to the fact that multiple lumbosacral and dorsal TCs can produce nerve injuries and serious movement disturbances, and (3) to document the usefulness of the magnetic resonance imaging and bone scan in non-invasive diagnosis and guiding management in such cases. These cysts are clearly identified by magnetic resonance imaging (MRI) and computerized tomography imaging of the lumbosacral spine. However, there are no reports on the scintigraphic findings of multilocular disseminated TC in literature. TCs are typically benign, asymptomatic lesions that can simply be monitored. To date, no consensus exists about the best surgical strategy to use when indicated.

    Full Text Available Progressive disseminated histoplasmosis (PDH caused by Histoplasma capsulatum generally develops in immunocompromised patients or those on long-term systemic corticosteroid therapy. Here, we report a case of PDH in an immunocompetent patient, which is a rare occurrence. A 56- year-old male patient, whose work often led him to caves, now reported with a low-grade fever and altered sensorium. Investigations revealed hyponatremia, bilateral adrenal enlargement, and mediastinal lymphadenopathy. A rare complication of the manifestations of histoplasmosis in an immunocompetent patient, in the form of ring lesions in the brain, came to light during the clinical investigations. The patient developed generalized tonic–clonic convulsions and needed care for the critical condition 2 weeks into treatment. This case report traces the clinical course, histological and serological findings, and response to amphotericin B therapy in the patient.

    Full Text Available Objective To study the clinical, neuroimaging and histopathological features of intracranial germinoma.  Methods One case of intracranial germinoma with ventricular system dissemination was reported, and related literatures were reviewed.  Results A 34-year-old male complained of progressive dizziness for 30 d and manifested unsteady gait for 45 d. Radiological examinations revealed low signal intensity on T1WI and hyperintense on T2WI in the corpus callosum, left cerebellum, around the fourth ventricle, aqueduct mesencephalon, the ventral pons and pineal region, with even or uneven enhancement after contrast. The clinical initial diagnosis was "intracranial multiple focal lesions and high possibility of multiple sclerosis". After well response to glucocorticoid impact and dehydration, the patient stopped taking drugs but presented relapse and exacerbation. Later, he underwent biopsy on pineal region and was diagnosed as intracranial germinoma. Microscopically, the big germ cells and lymphocytes coexisted. Tumor cells were epithelioid cells with transparent cytoplasm, prominent nuclei and mitotic activity. Lymphocytes were distributed along interstitial substance of vessel and fiber, and individual syncytiotrophoblasts were sprasely distributed. Immunohistochemical staining showed tumor cells were positive for CD117 and OCT3/4, and the syncytiotrophoblasts were positive for β-human chorionic gonadotropin ( β-hCG. The clinical symptoms were completely alleviated after radiotherapy and chemotherapy.  Conclusions Because of the sensitivity for radiotherapy and chemotherapy, intracranial germinoma can be diagnosed and treated early to improve its prognosis. However, it is very easy to disseminate along with ventricular system and form multiple lesions, leading to atypical clinical and imaging manifestations, which is a big challenge for clinical diagnosis. doi: 10.3969/j.issn.1672-6731.2014.05.010

    "A multiregional model of gross internal migration flows is presented in this article. The interdependence of economic factors across all regions is recognized by imposing a non-stochastic adding-up constraint that requires total inmigration to equal total outmigration in each time period. An iterated system estimation technique is used to obtain asymptotically consistent and efficient parameter estimates. The model is estimated for gross migration flows among the Canadian provinces over the period 1962-86 and then is used to examine the likelihood of a wash-out effect in net migration models. The results indicate that previous approaches that use net migration equations may not always be empirically justified."

    We study the Gross conjecture for the cyclotomic function field extension k(∧f)/k where k = Fq(t) is the rational function field and f is a monic polynomial in Fq[t].We prove the conjecture in the Fermat curve case(i.e., when f = t(t - 1)) by a direct calculation. We also prove the case when f is irreducible, which is analogous to the Weil reciprocity law. In the general case, we manage to show the weak version of the Gross conjecture here.

    Disseminated visceral coccidiosis (DVC) was unexpectedly recognized in a wild white-naped crane (Grits vipio) killed by phosphamidon insecticide. On gross pathologic examination, widely disseminated white nodules were found on the serosa of the proventriculus, gizzard, and intestine, as well as on the surface and in the parenchyma of liver, spleen, and cardiac muscle. Microscopically, asexual stages of a coccidia were observed in some nodules. However, the species of coccidia could not be determined because no oocysts were found on fecal examination. This is believed to be the first reported case of DVC in a wild white-naped crane infected with Eimeria spp.

    MR imaging criteria for diagnosing acute disseminated encephalomyelitis (ADEM) have not been clearly established. Due to the wide spectrum of differential considerations, new imaging features allowing early and accurate diagnosis for ADEM are needed. We hypothesized that ADEM lesions would be characterized by vasogenic edema due to the potential reversibility of the disease. Sixteen patients who met the diagnostic criteria for ADEM proposed by the International Pediatric Multiple Sclerosis Study Group (IPMSSG) and had complete MR imaging studies performed at our institution during the acute phase of the disease were identified retrospectively and evaluated by experienced pediatric neuroradiologists. Vasogenic edema was demonstrated on diffusion-weighted imaging (DWI) and corresponding apparent diffusion coefficient (ADC) maps in 12 out of 16 patients; cytotoxic edema was identified in two patients while the other two patients displayed no changes on DWI/ADC. ADC values for lesions and normal-appearing brain tissue were 1.39 ± 0.45 x 10{sup -3} and 0.81 ± 0.09 x 10{sup -3} mm/s{sup 2}, respectively (p = 0.002). When considering a cutoff of 5 days between acute and subacute disease, no difference between ADC values in acute vs. subacute phase was depicted. However, we found a significant correlation and an inverse and significant relationship between time and ADC value. We propose that vasogenic edema is a reliable diagnostic sign of acute neuroinflammation in ADEM. (orig.)

    Mobile devices integrating wireless short-range communication technologies make possible new applications for spontaneous communication, interaction and collaboration. An interesting approach is to use collaboration to facilitate communication when mobile devices are not able to establish direct communication paths. Opportunistic networks, formed when mobile devices communicate with each other while users are in close proximity, can help applications still exchange data in such cases. In opportunistic networks routes are built dynamically, as each mobile device acts according to the store-carry-and-forward paradigm. Thus, contacts between mobile devices are seen as opportunities to move data towards destination. In such networks data dissemination is done using forwarding and is usually based on a publish/subscribe model. Opportunistic data dissemination also raises questions concerning user privacy and incentives. Such problems are addressed di?erently by various opportunistic data dissemination techniques. ...

    2012-01-01

    Full Text Available Zygomycosis or mucormycosis refers to a group of uncommon but frequently fatal mycoses caused by fungi of the class Zygomycetes. The disease is usually an opportunistic infection in patients with diabetes, immunosuppression, trauma, burn wounds and other chronic debilitating diseases. Isolated renal involvement is rare although involvement of kidneys in disseminated mucormycosis is not uncommon. Clinical awareness and thorough appropriate investigations are required for an early diagnosis and successful treatment. We herein report a case of disseminated zygomycosis presenting as renal mass with pulmonary lesions, which was initially suspected to be disseminated renal cell carcinoma before a tissue diagnosis was obtained.

    Ruscalleda, J. [Hospital Sant Pau, Radiology Department, Neuroradiology, Barcelona (Spain)

    2005-03-01

    The sellar and parasellar region is an anatomically complex area that represents a crucial crossroad of important adjacent structures, e.g. orbits, cavernous sinus and its content, polygon of Willis, hypothalamus through the pituitary stalk and dural reflections forming the diaphragm sellae and the walls of the cavernous sinuses. Although the cavernous sinus represents the most relevant parasellar structure, from the practical and clinical point of view all the structures that surround the sella turcica can be included in the parasellar region. CT and, mainly, MRI are the imaging modalities to study and characterise the normal anatomy and the majority of processes in this region. We present a practical short review of the most relevant CT and MRI characteristics, such as location, nature of contrast enhancement and presence of cystic components, together with clinical findings, which permit differentiation of the most frequent and less common lesions found in the parasellar region. Learning objectives: A short review of the anatomy and clinical symptoms related to the parasellar region. Radiological characterisation, mainly by MRI, of the many lesions that alter the structure and function of sellar and parasellar anatomy. Description of the MRI features that permit differentiation among less common lesions. (orig.)

    2013-01-01

    Progressive disseminated histoplasmosis is a disease where Histoplasma capsulatum affects multiple organs due to the inability of host cellular immunity to control the infection. Progressive disseminated histoplasmosis mainly involves the bone marrow, liver, and lungs. We report an unusual initial presentation of progressive disseminated histoplasmosis presenting as acute tenosynovitis in a systemic lupus erythematosus (SLE) patient. This report highlights the point that H. capsulatum may present as focal lesions and a high level of suspicion is needed to make the diagnosis, especially in SLE patients. We specifically reviewed reported cases of progressive disseminated histoplasmosis in SLE patients, and a review of the literature is presented.

A total of 170 aerosol samples were collected from monitoring sites of Caichenmen village, Qinlian village, Xiajiawan village and Yangliucun village around the Qinshan NPP base. The measured specific activity of gross α and gross β are in the range of 0.02 ~ 0.38 mBq/m3 and 0.10 ~ 1.81 mBq/m3, respectively, with an average of 0.11 mBq/m3 and 0.45mBq/m3, respectively. They are lower than the average of 0.15 mBq/m3 and 0.52mBq/m3, of reference site at Hangzhou City. It is indicated that the specific activity of gross α and gross β for environmental aerosol samples around the Qinshan NPP base had not been increased in normal operating conditions of the NPP.

The majority of infections involving this dimorphic fungus are asymptomatic. Manifestations in symptomatic patients are diverse, ranging from flu-like illness to a more serious disseminated disease. We present here a case of chronic disseminated histoplasmosis mimicking a metastatic cancer. We reviewed the literature for cases of disseminated histoplasmosis presenting with hypercalcemia, focusing particularly on clinical presentation, risk factors predisposing for fungal infection, and outcome. We report a case of a 65-year-old diabetic male who presented with unexplained weight loss and hypercalcemia. Multiple brain space-occupying lesions and bilateral adrenal enlargement were evident on imaging studies. Biopsies showed caseating granulomas with budding yeast, consistent with histoplasmosis. The patient's symptoms resolved after liposomal amphotericin B and itraconazole therapy. Granulomatous diseases, including fungal infections, should be considered alongside malignancies, in patients with similar presentation.Keywords: disseminated histoplasmosis, hypercalcemia

    2012-01-01

    This paper stands for an application of the noncommutative (NC) Noether theorem, given in our previous work [AIP Proc 956 (2007) 55-60], for the NC complex Grosse-Wulkenhaar model. It provides with an extension of a recent work [Physics Letters B 653 (2007) 343-345]. The local conservation of energy-momentum tensors (EMTs) is recovered using improvement procedures based on Moyal algebraic techniques. Broken dilatation symmetry is discussed. NC gauge currents are also explicitly computed.

    Full Text Available Juvenile xanthogranuloma (JX is a rare, benign, non-Langerhans histiocytic proliferative disease that etiology is unknown. It is usually seen in children and infants. JX in adult is very rare. A 41-year-old female patient was admitted to our clinic with papules on her face, torso and extremities. A few lesions had occured 3 years ago on her face, they disseminated all over her body after having a traffic accident one year ago which for she had operations and she also concurrently was diagnosed asdiabetes mellitus (DM. Based on clinical and histopathological findings, the diagnosis of JX was made. There is no systemic involvement of JX detected. JX seen in adults are very rare and usually associated with hematological malignancy. The present case is a rare adult onset disseminated JX case without malignancy

  15. Malignant intraventricular meningioma with craniospinal dissemination and concurrent pulmonary metastasis

    Science.gov (United States)

    2014-01-01

    Background Malignant intraventricular meningiomas are quite rare and may spread along the craniospinal axis or extraneurally. However, simultaneous cerebrospinal dissemination and distal extraneural metastasis has seldom been reported. Case presentation A 51-year-old woman presented with recurrent anaplastic meningioma in the trigone of right lateral ventricle over a 1.5-year period. Suggested radiotherapy was refused after each operation. The patient showed a local relapse and dissemination around the previous tumoral cavity and along the spinal canal during the last recurrence. Left pulmonary metastasis was also found. She died despite multiple lesion resections. Conclusions Malignant intraventricular meningiomas are an uncommon subset of intracranial meningiomas, and have a great potential for intraneural and extraneural metastasis. Systemic investigation for metastasis is required after surgery, especially for those without adjuvant therapies. PMID:25073808

    Three genetic markers of Borrelia burgdorferi have been associated with disseminated disease: the OspC type, the 16S-23S rRNA intergenic spacer type (RST), and vlsE. Here, we modified previous methods so as to identify the three markers by PCR and restriction fragment length polymorphism in parallel, analyzed B. burgdorferi isolates from erythema migrans (EM) skin lesions in 91 patients, and correlated the results with evidence of dissemination. OspC type A was found approximately twice as frequently in patients with disseminated disease, whereas type K was identified approximately twice as often in those without evidence of dissemination, but these trends were not statistically significant. The remaining seven types identified were found nearly equally in patients with or without evidence of dissemination. RST 1 strains were significantly associated with dissemination (P=0.03), whereas RST 2 and RST 3 strains tended to have an inverse association with this outcome. The vlsE gene was identified in all 91 cases, using primer sets specific for an N-terminal sequence of B. burgdorferi strain B31 (vlsEB31) or strain 297 (vlsE297), but neither marker was associated with dissemination. Specific combinations of the three genetic markers usually occurred together. OspC type A was always found with RST 1 and vlsEB31, type K was always identified with RST 2 and more often with vlsE297, and types E and I were almost always found with RST 3 and equally often with vlsEB31 and vlsE297. We conclude that B. burgdorferi strains vary in their capacity to disseminate, but almost all strains isolated from EM lesions sometimes caused disseminated disease.

  18. Knowledge dissemination: a core mission

    CERN Multimedia

    2011-01-01

    It’s been a year since the CERN Council approved our policy on intellectual property management, so I’d like to take a look at what we’ve achieved since then. In short, a great deal. We’ve moved away from a fairly unregulated approach towards a well balanced and clearly defined system built around sound intellectual property management designed to deliver maximum dissemination and benefit for society from CERN innovation. It’s a move that I celebrate and fully support.   In 2009, CERN signed two partnership agreements to develop CERN technologies, two commercial licenses and eleven R&D licenses. Last year, the figures were six partnership agreements, five commercial licenses and twenty R&D licenses, indicating a real increase in dissemination efforts. From 2009 to 2010, however, the number of new technologies that were identified and disclosed hardly changed: nine in 2009, ten in 2010. These numbers are good, but we must improve, particu...

    Disseminated intravascular coagulation (DIC) is a serious complication of meningococcal septicaemia. It often results in infarction of various tissues namely the skin, adrenal glands, kidneys, brain and, much less commonly, bones. We describe a patient who presented bone lesions after meningococcal septicaemia. In addition to plain radiography and scintigraphy the lesions were evaluated with MRI and have proved to be extensive and still progressive, approxximately 18 months after the onset of the disease.

  5. Thrombocytopenia and thrombosis in disseminated intravascular coagulation (DIC).

    Science.gov (United States)

    Kitchens, Craig S

    2009-01-01

    Disseminated intravascular coagulation (DIC) is the physiologic result of pathologic overstimulation of the coagulation system. Despite multiple triggers, a myriad of laboratory abnormalities, and a clinical presentation ranging from gross hemostatic failure to life-threatening thrombosis, or even both simultaneously, a simplified clinical approach augmented by a few readily available tests allows prompt identification of the process and elucidation of treatment opportunities. Platelet counts in DIC may be low, especially in acute sepsis-associated DIC, yet increased in malignancy-associated chronic DIC. Thrombotic risk is not a function of the platelet count, and thrombocytopenia does not protect the patient from thrombosis. The stratification of both thrombotic risk and hemorrhagic risk will be addressed.

    2012-01-01

    The pathological and diagnostic features of a widely disseminated pleomorphic high-grade myofibroblastic sarcoma are described in a 23-year-old male brown bear (Ursus arctos horribilis). Firm, solid, white to tan neoplastic nodules, often with cavitated or soft grey-red necrotic centres, were observed throughout most internal organs, subcutaneous tissues and skeletal muscles on gross examination. Microscopically, the tumour consisted of pleomorphic spindle cells forming interlacing fascicles with a focal storiform pattern with large numbers of bizarre polygonal multinucleate cells, frequently within a collagenous stroma. Immunohistochemistry, Masson's trichrome stain and transmission electron microscopy designated the myofibroblast as the cell of origin. This is the first case of a high-grade myofibrosarcoma in a grizzly bear.

    A 48-year-old man with a 4 months history of asthenia, anorexia, 10 kg weight loss and 1 month of hematuria and dysuria was admitted to another hospital for sudden muscular weakness. He was found to have areflexic tetraparesis and was referred to our hospital.On admission, he was bradycardic, tachypneic, with flaccid tetraplegia. Laboratory results showed metabolic acidemia, severe hyperkalemia and hyponatremia, acute renal dysfunction and sterile pyuria. After hyperkalemia correction, the neurological symptoms resolved.On the second day, he became febrile and chest radiograph and CT images showed a pulmonary bilateral reticulomicronodular pattern, left hydronephrosis and diffuse bladder wall thickening. Disseminated tuberculosis was considered as diagnosis by the coexistence of this imagiologic alterations and sterile pyuria. Acid-fast test for Mycobacteriumtuberculosis was negative, but the urine culture became positive after 2 weeks.Antituberculosis treatment was started. One year later, he was asymptomatic and the structural urinary lesions had disappeared. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    Full Text Available No abstract available. Article truncated at 150 words. A 67-year-old African American man with no significant past medical history presented with shortness of breath and flu-like symptoms. On exam, he was noted to be profoundly hypoxemic with imaging showing diffuse thoracic changes (Figure 1 and a diffuse papular rash (Figure 2. Initial workup included coccidioidomycosis serologies which returned positive with a titer of 1:128. While exposure to coccidioidomycosis is very common in southern Arizona, dissemination is a rare occurrence. The incidence is estimated between 0.2 and 4.7 percent. Patients at highest risk include those that are immunosuppressed or that are of African or Filipino ancestry. Common extra-pulmonary sites include skin or subcutaneous tissue, meninges of brain or spinal cord, and bones. Even rarer sites include the eyes, liver, prostate, mediastinum, and kidneys. Treatment is usually the same as with pulmonary infection which is an azole agent. However, if the patient’s symptoms are severe or if the lesions involve …

    2016-01-01

    Full Text Available Glomuvenous malformations (GVMs present as asymptomatic multiple pink-to-blue nodules or plaques. Disseminated lesions are rare, representing 10% of all the cases. Familial cases are caused by mutations in the glomulin gene. A young male presented with multiple bluish-to-dusky red-coloured nodules 10-15 in numbers over the trunk, limbs and buttocks since 12 years of age. They ranged in size from 1 to 3 cm, partially to non-compressible and tender on palpation. There was no history of any systemic complaint. His sister and mother had similar lesions but in a limited distribution. Biopsy showed multiple ectatic dilated vascular channels lined by multiple layers of glomus cells consistent with the diagnosis of GVM. The biopsy of the lesions from the mother and sister also showed similar features. Mutation analysis for glomulin gene could not be done because of the unavailability of the facility at our setting. He underwent sclerotherapy with 3% polidocanol every 2 weeks, and there was significant improvement in the lesions after six sessions of sclerotherapy. The patient is under follow-up and there is no recurrence of the lesions over treated sites after 6 months.

    2005-01-01

    Baryons in the large N limit of (1+1)-dimensional Gross-Neveu models with either discrete or continuous chiral symmetry have long been known. We generalize their construction to the case where the symmetry is explicitly broken by a bare mass term in the Lagrangian. In the discrete symmetry case, the exact solution is found for arbitrary bare fermion mass, using the Hartree-Fock approach. In the continuous symmetry case, a derivative expansion allows us to rederive a formerly proposed Skyrme-type model and to compute systematically corrections to the leading order description based on an effective sine-Gordon theory.

    Histoplasmosis is a progressive disease caused by dimorphic intracellular fungi and can prove fatal. Usually, it is present in immunocompromised individuals and immunocompetent individuals in the endemic zones. We report an unusual presentation of progressive disseminated histoplasmosis. The patient in the present case report was immunocompetent child and had fever, bone pains, gradual weight loss, lymphadenopathy and hepatosplenomegaly. Disseminated histoplasmosis (DH) was diagnosed on microscopic examination and fungal culture of bone marrow, blood, skin biopsy and lymph node aspirate. The patient died on seventh day of amphotericin B. In the absence of predisposing factors and classical clinical presentation of febrile neutropenia, lung, adrenal and oropharyngeal lesions, the disease posed a diagnostic challenge. Progressive disseminated histoplasmosis in children can be fatal despite timely diagnosis and therapy. In India, disseminated histoplasmosis is seen in immunocompetent hosts. All the pediatrics immunocompetent cases from India are also reviewed.

    Full Text Available Introduction. Multiple myeloma is a hemathological malignancy characterized by the clonal proliferation of plasma cells in the bone the marrow. Extramedullary dissemination of multiple myeloma is uncommon. In several cases only, the multiple myeloma malignant plasma cells had diseminated to the lung parenchyma. Case report. We presented a case of multiple myeloma with lung plasmacytoma, in a 79-year-old patient, hospitalized for febrility and infiltrative mass in the right lung. Two months before the patient was admitted, because of developing terminal renal failure, hemodialysis treatment had started three times a week. Since then, the patient was oliguric, but because of febrility and hemoptysis that appeared, at first he was treated with dual antibiotic therapy which resulted in temporary improvement of his general condition, but pleural effusion remained. After thoracocentesis, followed by myelogram, the multiple myeloma diagnosis was established. Conclusion. In patients of middle and older age, with general weakness, exhaustion, loss of weight, renal failure which progresses to the end stage rapidly, if symptoms of respiratory tract occur, consider this uncommon disease - extramedullary dissemination of multiple myeloma.

  16. Small Bowel Dissemination of Coccidioidomycosis

    2015-01-01

    Full Text Available Gastrointestinal coccidioidomycosis is extremely rare, with less than 10 cases reported in the literature. We report a case of small bowel dissemination of coccidioidomycosis in a 21-year-old African American male with a history of living in San Joaquin Valley. The patient presented with one week of abdominal pain, nausea, shortness of breath, intermittent fever, and sweat, and one month of abdominal distention. A chest radiograph revealed complete effusion of left lung. A computed tomography scan of the abdomen showed diffuse small bowel thickening and enhancement, as well as omental and peritoneal nodules, and ascites. The coccidioidal complement fixation titer was 1 : 256. The duodenal biopsy revealed many spherules filled with round fungal endospores. Later, blood fungal culture showed positivity for Coccidioides immitis. The final diagnosis is disseminated coccidioidomycosis involving lungs, blood, and duodenum. Despite aggressive antifungal therapy, the patient’s clinical situation deteriorated and he succumbed to multisystem organ failure one and half months later. A high index of suspicion for gastrointestinal coccidioidomycosis should be maintained in patients from an endemic area presenting as abdominal distention and pain.

  17. Multiple Metastasis-Like Bone Lesions in Scintigraphic Imaging

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Multiple benign osteolytic lesions are very hard to differentiate from disseminated bone metastasis. Whole-body bone scintigraphy (WBBS with technetium-99m methylene diphosphonate (Tc-99m MDP demonstrates multiple lesions with increased uptake in any bone involved. Even combined with medical history and multiple imaging results, such as MRI and CT, the clinical diagnosis of metastasis lesion remains as a challenge. These clinical characteristics are similar to multiple malignant bone metastases and therefore affect the following treatment procedures. In this paper, we analyzed multiple benign osteolytic lesions, like eosinophilic granuloma (EG, multiple myeloma (MM, disseminated tuberculosis, fibrous dysplasia, or enchondroma, occurring in our daily clinical work and concluded that additional attention should be paid before giving the diagnosis of multiple bone metastases.

    2010-12-01

    In Japan, dissection of human body is generally prohibited by the Penal Code, i.e. the criminal law. However, the Postmortem Examination and Corpse Preservation Act allows for the dissection of the body in very limited situations, that include gross anatomy dissection and pathological and forensic autopsy in medical and dental schools. Growing numbers of co-medical schools have been founded more recently in Japan, and not a small number of co-medical schools try to adopt human body dissection in the course of anatomy education. The present short communication reminds us of the ways of thinking of the Postmortem Examination and Corpse Preservation Act and the Act on Body Donation for Medical and Dental Education in order that anatomy education in medical as well as co-medical schools takes place under the regulation by these two laws.

  19. Disseminated cutaneous sporotrichosis in a patient with AIDS: report of a case

    Directory of Open Access Journals (Sweden)

    Carvalho Miriam Tomoko Mitsuno

    2002-01-01

    Full Text Available We describe a case report of disseminated cutaneous sporotrichosis as the initial presentation of AIDS in a 24-year-old HIV-positive male patient. He presented multiple ulcerated skin lesions distributed over the face, thorax, legs and arms. Biopsy of one of the cutaneous lesions was suggestive of sporotrichosis and culture isolated Sporothrix schenckii. Itraconazole was started and the lesions progressively resolved after 15 days of medication. The patient was discharged with this medication but he did not return for follow-up. He died three months later in another hospital. Therapy of sporotrichosis in HIV-infected patients remains unclear and the response to therapy is variable. Itraconazole is highly concentrated in the skin and is one of the options for treatment of disseminated sporotrichosis.

    The spine is the most common site of skeletal involvement in tuberculosis. The radiologic features are reportedly characterized by destruction of the vertebral body, subligamentous extension or subchondral penetration, frequent paravertebral abscess formation and late involvement of the disk space. We experienced a case of a 25-year-old male who was a human immunodeficiency virus carrier without antiretroviral therapy. Incidental findings on abdominal computed tomography included multiple well-demarcated and ovoid osteolytic lesions with hyperdense rims disseminated in the thoracic, lumbar, and sacrum vertebrae, as well as in both ilii. On the lumbar spine magnetic resonance imaging, multiple small round lesions of isointense signal intensity with peripheral hyperintense rims were found on both T1- and T2-weighted imaging. The lesions had peripheral rim enhancement on gadolinium-enhanced T1-weighted imaging. Based on our experience, this rare image finding is one of the manifestations of disseminated tuberculosis.

    2013-01-01

    Full Text Available Fusarium species are common soil-inhabiting organisms and plant pathogens. Human infections are usually precipitated by local or systemic predisposing factors, and disseminated infection is associated with impaired immune responses. Skin infections caused by Fusarium spp. include keratitis, onychomycosis, mycetoma, painful discrete erythematous nodules. Hyperkeratotic skin lesions caused by Fusarium spp. are, however, rarely reported. We report a case of hyperkeratotic verrucous warty skin lesion in the foot of a 50-year-old immunocompetent male, farmer by occupation.

  2. Robust Principal Component Test in Gross Error Detection and Identification

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    Principle component analysis (PCA) based chi-square test is more sensitive to subtle gross errors and has greater power to correctly detect gross errors than classical chi-square test. However, classical principal component test (PCT) is non-robust and can be very sensitive to one or more outliers. In this paper, a Huber function liked robust weight factor was added in the collective chi-square test to eliminate the influence of gross errors on the PCT. Meanwhile, robust chi-square test was applied to modified simultaneous estimation of gross error (MSEGE) strategy to detect and identify multiple gross errors. Simulation results show that the proposed robust test can reduce the possibility of type Ⅱ errors effectively. Adding robust chi-square test into MSEGE does not obviously improve the power of multiple gross error identification, the proposed approach considers the influence of outliers on hypothesis statistic test and is more reasonable.

    Obstetrical disseminated intravascular coagulation (DIC) is usually a very acute, serious complication of pregnancy. The obstetrical DIC score helps with making a prompt diagnosis and starting treatment early. This DIC score, in which higher scores are given for clinical parameters rather than for laboratory parameters, has three components: (i) the underlying diseases; (ii) the clinical symptoms; and (iii) the laboratory findings (coagulation tests). It is justifiably appropriate to initiate therapy for DIC when the obstetrical DIC score reaches 8 points or more before obtaining the results of coagulation tests. Improvement of blood coagulation tests and clinical symptoms are essential to the efficacy evaluation for treatment after a diagnosis of obstetrical DIC. Therefore, the efficacy evaluation criteria for obstetrical DIC are also defined to enable follow-up of the clinical efficacy of DIC therapy.

    Disseminated intravascular coagulation (DIC) is a syndrome characterized by systemic activation of blood coagulation, generation of thrombin, and leading to disturbance of the microvasculature. In this article, definition and diagnostic criteria of DIC depend on the International Society of Thrombosis and Haemostasis (ISTH). There is no gold standard for diagnosis of DIC, only low quality evidence is used in general practice. Many diagnostic tests and repeated measurement are required. For the treatment of DIC, there is no good quality evidence. The most important treatment for DIC is the specific treatment of the conditions associated DIC. Platelets and/or plasma transfusion may be also necessary if indicated. Nevertheless, there is no gold standard for diagnosis and treatment of DIC, we use only low quality evidence in general practice.

    Ninety-six, randomly selected Swedish cats were evaluated for the presence of dental resorptive lesions. All cats were examined while receiving general anesthesia. Diagnosis was based on oral examination and full-mouth, intraoral dental radiographs. Information concerning age, sex, vaccination status, eating habits, food type, environment (indoor or outdoor housing), oral, discomfort, dental care, and medical treatment was recorded. Hematologic samples included analysis for FeLV, FIV, and calcivirus. Of the cats examined in this study, 32% had gross or radiographic signs of dental resorptive lesions. There was a positive relationship between the occurrence of dental resorptive lesions and increasing age.

  6. Effect of temperate climate tree species on gross ammonification, gross nitrification and N2O formation

    Microbial nitrogen turnover processes in the soil, like ammonification, nitrification and denitrification, play an important role in the formation of nitrous oxide (N2O): (i) ammonification, because it releases nitrogen from organic material in the form of ammonium (NH4+), which in turn can serve as substrate for nitrification; (ii) nitrification itself (i.e. the turnover of NH4+ to nitrate, NO3-), during which nitric oxide (NO) and N2O can be released as by-products at varying ratios; (iii) denitrification, in which NO3- serves as electron acceptor and is converted to molecular nitrogen (N2) via NO and N2O as intermediates, that can also be partially lost to the atmosphere. Temperate forest soils are a substantial source of atmospheric N2O contributing up to 10% to the total atmospheric N2O budget. However, this figure is afflicted with a huge uncertainty due to a number of factors governing the soil N2O formation, consumption, release and uptake, which are not fully understood at present. To one of these factors belongs the influence of the tree species on nitrogen turnover processes in the soil and the formation of N trace gases related with them. The aim of the present work was to analyse this tree species effect for the temperate climate region. For this purpose the effect of five different temperate tree species, having the same age and growing on the same soil in direct vicinity to each other, on gross ammonification and gross nitrification as well as on N2O formation was investigated. The trees (common beech, Fagus sylvatica; pedunculate oak, Quercus robur; Norway spruce, Picea abies; Japanese larch, Larix leptolepis; mountain pine, Pinus mugo) were part of a species trial in Western Jutland, Denmark, established in 1965 on a former sandy heathland. Samples from the soil under these five tree species were taken in spring and in summer 2002, respectively, differentiating between organic layer and mineral soil. The gross rates of ammonification as well of

    Pigmented villonodular synovitis (PVNS) is a rare proliferative disease involving synovial membranes. Natural history and etiology of PVNS are not well known. PVNS presents as localized or diffuse tumor like nodular lesion of the synovial lining of the joint and the synovial spaces adjacent to the joints. Though histologically benign, it is a very aggressive lesion, capable of bone destruction and widespread infiltration of surrounding tissues. Standard therapy is surgical resection, but due to the infiltrative growth, the recurrence rate is significantly high. After several relapses surgical treatment of diffuse PVNS becomes difficult and may require amputation of the involved limb. Radiotherapy can provide an effective treatment option for patients with large lesions or lesions which are not suitable for surgery, after incomplete resection to prevent relapses or to avoid amputation. We report 2 cases of diffuse PVNS in the knee joint treated with arthroscopic gross total synovectomy and radiotherapy.

    A 44-year-old alcoholic (and therefore immunocompromised) hospital cleaner presented with general malaise, weight loss, and erythematous skin nodules. Computed tomography scanning revealed a neck mass invading the thyroid gland, pulmonary infiltrates, liver lesions, and deposits on the anterior abdominal wall, consistent with disseminated malignancy. However, tissue diagnosis showed a necro-inflammatory process with no evidence of malignancy. Microscopy and culture of samples failed to detect any infectious pathogen, but after an extended incubation period, Finegoldia magna was isolated. This case study illustrates the importance of tissue diagnosis in suspected disseminated malignancy and raises the risk of acquiring the rarer bacteria amongst hospital staff.

    2013-02-01

    This study investigated how agricultural policy reforms, including market liberalization and market deregulation, have influenced gross revenue risk of Swiss dairy producers using farm-level panel data between 1990 and 2009. Based on detrended data, variance decomposition was applied to assess how output prices and yields contributed to revenue risk over 3 different periods: the whole period (1990-2009), the first decade (1990-1999), and the second decade (1999-2009). In addition, the effect of expected changes in animal-based support for roughage-consuming cattle and price volatility on revenue risk was evaluated using a simulation model. Prices were the main contributor to revenue risk, even if the importance of yield risk increased over time. Swiss dairy producers can profit from natural hedge but market deregulation and market liberalization have reduced the natural hedge at the farm level. An increase in price volatility would substantially increase revenue risk and would, together with the abandonment of direct payments, reduce the comparative advantage of dairy production for risk-averse decision makers. Depending on other available risk management strategies, price risk management instruments might be a valuable solution for Swiss dairy producers in the future.

    Full Text Available Patients with rheumatoid arthritis (RA have 2-fold increased risk of herpes zoster. In literature, limited information exists about disseminated cutaneous zoster in RA patients. An 83-year-old African-American female with RA presented with generalized and widespread vesicular rash covering her entire body. Comorbidities include hypertension, type II diabetes, and dyslipidemia. Patient was on methotrexate 12.5 mg and was not receiving any corticosteroids, anti-TNF therapy, or other biological agents. The patient was afebrile (98 F with no SIRS criteria. Multiple vesicular lesions were present covering patient’s entire body including face. Lesions were in different stages, some umbilicated with diameter of 2–7 cm. Many lesions have a rim of erythema with no discharge. On admission, patient was also pancytopenic with leukocyte count of 1.70 k/mm3. Biopsies of lesions were performed, which were positive for Varicella antigen. Subsequently, patient was started on Acyclovir. The patient’s clinical status improved and rash resolved. Our patient presented with “atypical” clinical picture of disseminated cutaneous zoster with no obvious dermatome involvement. Disseminated zoster is a potentially serious infection that can have an atypical presentation in patients with immunocompromised status. High index of suspicion is needed to make the diagnosis promptly and to initiate therapy to decrease mortality and morbidity.

    This review examines handling and processing of spleen biopsies and splenectomy specimens with the aim of providing the pathologist with guidance in optimizing examination and diagnosis of splenic disorders. It also offers recommendations as to relevant reporting factors in gross examination, which may guide diagnostic workup. The role of splenic needle biopsies is discussed. The International Spleen Consortium is a group dedicated to promoting education and research on the anatomy, physiology, and pathology of the spleen. In keeping with these goals, we have undertaken to provide guidelines for gross examination, sectioning, and sampling of spleen tissue to optimize diagnosis (Burke). The pathology of the spleen may be complicated in routine practice due to a number of factors. Among these are lack of familiarity with lesions, complex histopathology, mimicry within several types of lesions, and overall rarity. To optimize diagnosis, appropriate handling and processing of splenic tissue are crucial. The importance of complete and accurate clinical history cannot be overstated. In many cases, significant clinical history such as previous lymphoproliferative disorders, hematologic disorders, trauma, etc, can provide important information to guide the evaluation of spleen specimens. Clinical information helps plan for appropriate processing of the spleen specimen. The pathologist should encourage surgical colleagues, who typically provide the specimens, to include as much clinical information as possible.

    Full Text Available Introduction. Bronchial carcinoids belong to a rare type of lung tumors. If they do not expose outstanding neuroendocrine activity, they develop without clearly visible symptoms. They are often detected during a routine examination. According to their clinical pathological features, they are divided into typical and atypical tumors. Typical bronchial carcinoids metastasize to distant organs very rarely. Localized forms are effectively treated by surgery. The methods of conservative treatment should be applied in other cases. Case report. We presented a 65-year-old patient with carcinoid lung tumor detected by a routine examination. Additional analysis (chest X-ray, computed tomography of the chest, ultrasound of the abdomen, skeletal scintigraphy, bronhoscopy, histopathological analysis of the bioptate of bronchial tumor, as well as bronchial brushing cytology and immunohistochemical staining performed with markers specific for neuroendocrine tumor proved a morphologically typical lung carcinoid with dissemination to the liver and skeletal system, which is very rarely found in typical carcinoids. Conclusion. The presented case with carcinoid used to be showed morphological and pathohistological characteristics of typical bronchial carcinoid. With its metastasis to the liver and skeletal system it demonstrated unusual clinical course that used to be considered as rare phenomenon. Due to its frequent asymptomatic course and varied manifestation, bronchial carcinoid could be considered as a diagnostic challenge requiring a multidisciplinary approach.

    A loggerhead sea turtle (Caretta caretta) was found stranded alive along the Adriatic coast close to Ancona, Italy, displaying obtundation, tachypnea, and increased respiratory effort. It died a few hours after admission, and a postmortem examination was immediately performed. Miliary yellowish nodules were evident in the liver, and a lower number in the heart, stomach, and gut wall. Hundreds of whitish nodules were scattered in the lungs, with the majority of the pulmonary parenchyma being replaced by the lesions. Histologically, all nodular lesions consisted of a small central area of necrosis with acid-fast bacilli surrounded by epithelioid cells, macrophages, and lymphocytes. Giant cells were found in the spleen and the liver. Kidneys, lungs, liver, spleen, brain, and skin lesions were inoculated aseptically onto general isolation media and selective isolation media for mycobacteria. The isolate showed a restriction pattern identical to Mycobacterium chelonae by polymerase chain reaction-restriction fragment length polymorphism. To the best of the authors' knowledge, this is the first description of a disseminated infection caused by a potentially pathogenic mycobacteria in a stranded, free-ranging loggerhead sea turtle. Veterinary staff and biologists who handle sea turtles with suspected mycobacterial disease should protect themselves appropriately.

  7. Gross and histologic features of gastritis due to Ophidascaris arndti in tropical rattlesnakes ( Crotalus durissus

    É.M. Mello

    Full Text Available ABSTRACT The tropical rattlesnake (Crotalus durissus is a snake of great importance for biomedical industry since its poison is used for the production of antiophidic serum and researches. Several conditions related to animal health, such as diseases and parasites, which can promote the reduction of poison production by these snakes should be investigated. Accordingly, the aim of this study was to characterize the gross and microscopic lesions related to the presence of Ophidascaris arndti in stomachs of tropical rattlesnakes. The gastrointestinal tract of thirty-five South American rattlesnakes captured in Southeastern region of Brazil were analyzed and nineteen animals showed infestation by the parasites, found in the small intestine and, especially, in the stomach of the hosts. Grossly, lesions were characterized by mucosal ulcers occasionally associated with hemorrhage. Microscopic alterations included histiocytic granulomas, fibrosis, necrosis, and hemorrhage. Based on these findings, the diagnosis of a parasitic granulomatous disease was made. The lesions may be related to the cause of death in captivity snakes, since the lesions can promote secondary infections by opportunistic bacteria. Moreover, the intense inflammatory response accompanied by fibrosis may be related to poor functioning of the gastric snakes, which it may exhibit frequent regurgitation of the food.

  8. Estimating the gross moist stability in shallow and deep convection

    2015-12-01

    Gross moist stability has been used to study the link between tropical deep convection and large scale circulation in a moist static energy (MSE) budget. Here we aim to calculate the gross moist stability from more realistic profiles of vertical velocity and extend it beyond deep convection, adding shallow convection. Based on a principal component analysis, we were able to decompose the vertical velocity into two leading modes, which are dominated by deep and shallow convection, respectively. According to the deep and shallow modes, we calculate the gross moist stability for these two modes and discuss the roles of deep and shallow convection in the MSE budget. The gross moist stability of deep convection tends to be positive in the tropics, while that of shallow convection is negative over most areas of the tropics. This implies that deep convection exports MSE to stabilize the atmosphere and shallow convection imports MSE to enhance deep convection and destabilize the atmosphere. Based on the spatial distribution, moisture tends to reduce the gross moist stability of deep convection, while dry static energy has little impact. Deeper deep convection tends to have greater gross moist stability. For shallow convection, on the other hand, the gross moist stability is affected not only by low-level moisture but also mid-level moisture. Both moister low-level and drier mid-level moisture reduce the gross moist stability of shallow convection. Greater low-level dry static energy, which is associated with warmer sea surface temperature, also tends to reduce gross moist stability.

    Philipp Bäumer

    Full Text Available PURPOSE: Patients with ulnar neuropathy of unclear etiology occasionally present with lesion extension from elbow to upper arm level on MRI. This study investigated whether MRI thereby distinguishes multifocal neuropathy from focal-compressive neuropathy at the elbow. METHODS: This prospective study was approved by the institutional ethics committee and written informed consent was obtained from all participants. 122 patients with ulnar mononeuropathy of undetermined localization and etiology by clinical and electrophysiological examination were assessed by MRI at upper arm and elbow level using T2-weighted fat-saturated sequences at 3T. Twenty-one patients were identified with proximal ulnar nerve lesions and evaluated for findings suggestive of disseminated neuropathy (i subclinical lesions in other nerves, (ii unfavorable outcome after previous decompressive elbow surgery, and (iii subsequent diagnosis of inflammatory or other disseminated neuropathy. Two groups served as controls for quantitative analysis of nerve-to-muscle signal intensity ratios: 20 subjects with typical focal ulnar neuropathy at the elbow and 20 healthy subjects. RESULTS: In the group of 21 patients with proximal ulnar nerve lesion extension, T2-w ulnar nerve signal was significantly (p<0.001 higher at upper arm level than in both control groups. A cut-off value of 1.92 for maximum nerve-to-muscle signal intensity ratio was found to be sensitive (86% and specific (100% to discriminate this group. Ten patients (48% exhibited additional T2-w lesions in the median and/or radial nerve. Another ten (48% had previously undergone elbow surgery without satisfying outcome. Clinical follow-up was available in 15 (71% and revealed definitive diagnoses of multifocal neuropathy of various etiologies in four patients. In another eight, diagnoses could not yet be considered definitive but were consistent with multifocal neuropathy. CONCLUSION: Proximal ulnar nerve T2 lesions at upper

    Classical swine fever (CSF) is a multi-systemic disease that can be accompanied by severe haemorrhagic lesions. The underlying pathogenetic mechanisms are still far from being understood, though disseminated intravascular coagulation (DIC) was discussed as a major factor. In the presented study, the direct thrombin inhibitor hirudin was used in an attempt to elucidate the role of the coagulation system in the pathogenesis of CSF-induced haemorrhagic lesions. Two groups of piglets (n=5) were infected with highly virulent CSF virus (CSFV) strain CSF0634. One group underwent daily treatment with hirudin, the other served as untreated challenge infection control. Assessment of clinical signs using a clinical score system, coagulation tests, and blood counts were performed daily. Both groups developed acute-lethal CSF with haemorrhagic lesions. Although changes in the coagulation system were seen in the late stages of CSFV infection, our results strongly suggest that DIC does not present the crucial event in the pathogenesis of haemorrhagic lesions.

  11. Neuroleptic Malignant Syndrome Associated with Refractory Acute Disseminated Encephalomyelitis

    Directory of Open Access Journals (Sweden)

    Silvia R. Delgado

    2016-04-01

    Full Text Available We present the case of a young man who was transferred to our hospital with worsening acute disseminated encephalomyelitis (ADEM despite treatment with intravenous methylprednisolone, intravenous immunoglobulin and plasma exchange. He developed neuroleptic malignant syndrome (NMS without the use of dopamine-modulating drugs. His progressive clinical improvement started after treatment with intravenous cyclophosphamide and methylprednisolone. In our patient, acute demyelination with severe bilateral inflammation of the basal ganglia could have caused a state of central dopamine depletion, creating proper conditions for the development of NMS. Significant clinical improvement of our case after treatment with intravenous cyclophosphamide and steroids provides further evidence for a possible role of the inflammatory lesions in the pathogenesis of NMS in association with ADEM.

    2008-12-01

    A 4-year-old spayed female mixed breed dog was referred to the Michigan State University, Veterinary Teaching Hospital (MSU-VTH) with vomiting, lethargy and anorexia of 2 weeks duration. Abdominal radiographs and ultrasonography showed hepatosplenomegaly. Cytological evaluation of ultrasound-guided fine needle aspirates of the liver and spleen revealed fungal organisms and pyogranulomatous inflammation; fungal culture documented Paecilomyces variotii infection. The dog received antifungal therapy and supportive care. Multiple firm plaque-like skin lesions, predominantly involving the inguinal region, developed 18 days after initial presentation and were diagnosed histopathologically as calcinosis cutis. While generalized calcinosis cutis has been reported in three dogs with blastomycosis and one dog with leptospirosis, the association with disseminated Paecilomyces spp. infection is novel.

The amplified products were analyzed by LSSP-PCR to investigate the genetic variability of the parasite populations present in different anatomical sites. Twenty-three out of the 52 samples gave PCR-positive results. The existence of L. (V. braziliensis strains that remained restricted to cutaneous lesions and others showing characteristics of dissemination to internal organs and healthy skin was observed. LSSP-PCR and numerical analyses revealed that parasite populations that do not disseminate were genetically similar and belonged to a separate phenetic cluster. In contrast, populations that showed spreading to internal organs displayed a more polymorphic genetic profile. Despite the heterogeneity, L. (V. braziliensis populations with identical genetic profiles were observed in popliteal and cervical lymph nodes of the same animal. Our results indicate that infection in dogs can be manifested by dissemination and tissue tropism of genetically distinct populations of L. (V. braziliensis.

    Rhodococcus (R). equi, a recognized pathogen in horses, is emerging as a human opportunistic pathogen, especially in immunocompromized people. It affects also New World camelids, but there are no reports of R. equi infection in Old World camelids yet. Four cases of disseminated R. equi infection in adult breeding dromedaries occurred at one camel farm near Dubai within 16 months of each other. At necropsy the lungs were diffusely consolidated with large caseous areas. Histology revealed severe suppurative to necrotising pneumonia with multiple encapsulated abscesses. Immunohistochemistry enabled the detection of 15- to 17-kDa antigens (VapA) of R. equi in the lung sections. High numbers of R. equi were isolated from the lung lesions as well as from liver, spleen and mediastinal lymph nodes, indicative of septicaemia. The isolated strains were PCR-positive for the specific virulence plasmid (VapA-Gen) of R. equi, indicating virulent strains and containing an 85-kb type I plasmid. This is the first report of disseminated R. equi infection in Old World camelids. Since adult camels in general do not suffer from bacterial caused pneumonia (except tuberculosis), this is a new emerging disease for camels.

    Full Text Available Gonorrhea is one of the most common sexually transmitted diseases in the US with 700,000 annual cases. Although most cases of gonorrhea are localized, approximately 0.5–3% become disseminated. Here we discuss a rare case of a patient with systemic lupus erythematosus (SLE who developed septic shock from disseminated gonorrhea infection (DGI. Our patient is a 24-year-old woman with SLE, mixed connective tissue disease with cutaneous vasculitis, and lupus nephritis who presented with several weeks of malaise and generalized body aches associated with a diffuse rash along her fingers, palms, and trunk. Infectious workup was unrevealing with the exception of a positive gonorrhea test obtained from a cervical swab. Given her symptoms of tenosynovitis, the appearance of her skin lesions, and her positive gonorrhea test, she was diagnosed with septic shock secondary to DGI. With antibiotic treatment, the patient reported a dramatic improvement of the pain in her swollen joints and her rash receded. Patients diagnosed with SLE carry an increased risk of gonorrhea regardless of whether or not they are being treated for their SLE. Although it is well-documented that SLE is associated with severe DGI, few describe it resulting in overt septic shock.

    Full Text Available Aim: To evaluate the number of lesions of psoriasis and to find risk factors for multiple lesions. Material and Methods: 1,236 patients (male 54.13%, female 45.87% with psoriasis were seen over a period of 8 years in an Outpatient Clinic. Patients filled out questionnaires containing age at onset, number of lesions and location at the beginning of the disease, gender, type and localization of psoriasis at the time of clinical examination, psoriasis family history, previous treatment, comorbidities, and social status. Results: The number of psoriasis lesions correlates with: onset age of psoriasis (F=8.902, p=0.0029; age at the moment of clinical examination (F=8.902, p=0.0029; residence in rural area (χ2=8.589, p=0.00338, 95%CI; alcohol intake (χ2=16.47, p=0.00005, 95%CI; smoking (χ2=8.408, p=0.00373, 95%CI; occupation: workers/pupils/students (χ2=14.11, p=0.0069, 95%CI. Conclusions: There is a correlation between number of psoriatic lesions and some factors. Multiple lesions were observed in older patients, smokers and drinkers, coming from rural area and social active (workers and pupils/students. No correlation was statistically proved between number of lesions and gender, comorbidities and family history of psoriasis.

    1995-09-01

    Between January 1986 and August 1991, 19 patients with alimentary tract cancers complicated by peritoneal dissemination received whole abdominal irradiation combined with intraperitoneal chemotherapy postoperatively. Using a moving-strip technique of irradiation, 12.0 Gy was delivered in three fractions to the entire abdominal contents with partial liver and kidney shielding. The primary tumor sites were the stomach in 12 patients, the colorectum in five, and the gall bladder in two. Nine patients with gross residual disease also received a limited field boost of 30.6 Gy in 17 fractions after completion of treatment to the whole abdomen. None of the patients failed to complete the planned dose despite acute gastrointestinal toxicity (nausea and vomiting, 84%, diarrhea and cramping, 78%) and acute hematologic toxicity (leukocytopenia, 84%, thrombocytopenia, 68%). Our follow-up study revealed that the actuarial one-year survival rate was 28.4% and the median survival time was 9.0 months. Survival rates at one-year for patients with colorectal and gastric cancer were 75.0% and 16.7%, respectively. Patients with gastric cancer (n=12) had a poorer outcome than those with colorectal cancer (n=5) in the present study. One reason for this difference may have been the presence of cancerous pleuritis, which was frequently observed in patients with gastric cancer. Therefore, more intensive treatment to prevent cancerous pleuritis seems to be necessary to improve the efficacy of whole abdominal irradiation. (author).

    Disseminated signet ring cell carcinomas frequently arise from the stomach. However, primaries in the colon and rectum have also been reported. We present a 68 year old lady who presented with a change in her bowel habit. Colonoscopy showed a stenosing rectal tumour at 7 cm to 8 cm from the anal verge. Multiple scattered ulcers were also noted along the entire length of the colon. Biopsy of the lesions revealed signet ring cell adenocarcinoma. Gastroscopy showed multiple nodules with ulceration over several areas of the stomach which were similar in appearance to the colonic lesions. However, no primary tumour of the stomach was seen. Biopsy of the gastric lesions also showed signet ring cell adenocarcinoma. Computed tomography scan of the abdomen and pelvis revealed circumferential tumour at the rectosigmoid junction with possible invasion into the left ischiorectal fossa. The overall picture was that of a primary rectal signet ring cell carcinoma with peritoneal dissemination. The patient was referred for palliative chemotherapy in view of the disseminated disease. In the present report, we discuss this interesting pathological entity and review the role of various histolological techniques in helping to identify the primary tumor.

    Necrobiosis lipoidica (NL) is a rare dermatosis that has been shown to precede the onset of diabetes mellitus in 15% of patients. It is more common in women; the average age of the onset is 30 years. Skin lesions of classic NL begin as a small papule, typically on the bilateral pretibial area. Progressively, these papules become indurated plaques with an atrophic, yellow center and multiple telangiectatic vessels, and brown-violaceous borders. We present the case of a 57-year-old male with type II diabetes mellitus from 2004, class II obesity, hepatosteatosis and metabolic disturbances who presents a disseminated eruption from 2010, formed by indurated plaques with flattened centers and a tendency of atrophy and raised, sharply demarcated, red-violaceous borders, having a variable diameter between 1.5 and 5 cm. The laboratory findings revealed elevated glucose levels between 250 and 300 mg%, high levels of transaminases and lipids. Diagnosis of disseminated necrobiosis lipoidica granuloma annulare-type was histopathologically confirmed. For the treatment, we have used topical corticosteroids and Tacrolimus 0.1% and systemic vasodilators. We consider this rare case interesting because has some peculiarities, as: disseminated lesions extend over the characteristic areas for necrobiosis lipoidica, the characteristic features of lesions similar to granuloma annulare, gender (male) and the onset of the disease over fifth decade.

  14. ESID, dissemination, and community psychology: a case of partial implementation?

    2003-12-01

    Dissemination, the second stage of Experimental Social Innovation and Dissemination (ESID) is a critical, if not defining, element of this social change model. This paper attempts to assess the extent to which community psychology has adopted and implemented ESID's dissemination focus in its training and publications. We identify four levels of commitment to dissemination: dissemination advocate, dissemination activist, dissemination researcher, and experimental dissemination researcher. Content analyses of textbooks, journal publications, and conference papers and a brief survey of doctoral training in the field were conducted. Findings suggest that the dissemination aspects of ESID have been modestly and partially implemented within the field. That is, although there is some evidence of a commitment to dissemination practice (advocate, activist), there is much less evidence of a commitment to dissemination research. The implications of these findings for the effectiveness of the ESID model and for training and practice in community psychology are discussed.

    Gross and microscopic evaluations of the ovaries of sheep subjected to successive ovum collection were performed with the objective of identifying if there was interference in oocyte production and morphology of gonads. Gross evaluation of the internal genital tract was also performed. Eighteen ewes of the Santa Inês breed were randomly distributed into three experimental groups of six animals each; G0, G1 and G9 with no, one and nine repetitions, respectively. Estrous synchronization was achieved with a short protocol using MAP followed by single dose stimulation with 80mg of FSHp and 300 IU of eCG (IM). Laparoscopic ovum pick-up was performed 36h later, with 7-day intervals. The number of visualized follicles, aspirated follicles and oocytes recovery was recorded. After the last intervention, ovariectomy was performed for evaluation of gross and microscopical appearance and existence of lesions caused by follicular puncture, which were classified as absent (0), mild (1), moderate (2) and severe (3). The number of visualized follicles, aspirated follicles and oocytes recovery were 13.2±2.0, 11.3±3.0 and 5.8±2.3, respectively, with a recovery rate of 51.7%. No statistical difference was found between the nine sessions (P>0.05). Nine sessions of superovulation and ovum collection procedures did not cause ovarian lesions and did not interfere with the production of follicles in ewes of the Santa Inês breed.

    Gross anatomy is considered one of the most important basic science courses in medical education, yet few medical schools require its completion prior to matriculation. The effect of taking anatomy courses before entering medical school on performance in medical gross anatomy has been previously studied with inconsistent results. The effect of premedical anatomy coursework on performance in medical gross anatomy, overall medical school grade point average (GPA), and Comprehensive Osteopathic Medical Licensing Examination Level 1 (COMLEX 1) score was evaluated in 456 first-year osteopathic medical students along with a survey on its perceived benefits on success in medical gross anatomy course. No significant differences were found in gross anatomy grade, GPA, or COMLEX 1 score between students with premedical anatomy coursework and those without. However, significant differences and higher scores were observed in students who had taken three or more undergraduate anatomy courses including at least one with cadaveric laboratory. There was significantly lower perceived benefit for academic success in the medical gross anatomy course (P<.001) from those students who had taken premedical anatomy courses (5.9 of 10) compared with those who had not (8.2 of 10). Results suggest that requiring any anatomy course as a prerequisite for medical school would not have significant effect on student performance in the medical gross anatomy course. However, requiring more specific anatomy coursework including taking three or more undergraduate anatomy courses, one with cadaveric laboratory component, may result in higher medical gross anatomy grades, medical school GPA, and COMLEX 1 scores.

    Abstract In this study, we describe clinical and imaging spectrum, and the natural course of patients with disseminated cysticercosis. How albendazole affects the course of disease has also been evaluated. We assessed the Toll-like receptor-4 gene polymorphisms, to know the reason for the apparently higher prevalence of disseminated cysticercosis in India. Sixty consecutive patients with disseminated cysticercosis were enrolled. Sixty age-and-sex-matched healthy controls were also enrolled for the purpose of genetic study. Twenty patients, who gave consent, were treated with albendazole along with corticosteroids. Forty patients did not give consent for antiparasitic therapy. Assessment for Toll-like receptor-4 gene polymorphisms (Asp299Gly and Thr399Ile genes) was done. Patients were followed for 6 months. We also performed a literature search of cases published in English language using PubMed electronic database and analyzed 56 cases thus available. There was an increased risk (6.63 fold and 4.61 fold) of disseminated cysticercosis in the presence of Asp299Gly and Thr399Ile polymorphisms in Toll-like receptor-4, respectively. The allelic frequency of Gly (11% vs. 3%, P = 0.024, odds ratio [OR] = 3.52) and Ile alleles (11% vs. 2%, P = 0.009, OR = 4.738) in disseminated cysticercosis was high. Albendazole resulted in complete disappearance of all cerebral lesions in 35% (7/20) patients and reduction in lesion load in remaining 65% (13/20) patients. No significant change in number of cysticercal lesion was noted in patients who did not receive albendazole. No major adverse reaction following antiparasitic treatment was noted. Three deaths were recorded in patients who did not receive antiparasitic treatment. Of the 56 cases reported in PubMed, 33 patients received antiparasitic treatment with follow-up data available for 31 patients. Most (24) of these patients received albendazole. A significant clinical and/or imaging improvements, on follow up, were observed in

    The value of /sup 67/Ga and methylene diphosphonate labeled with /sup 99m/Tc in detecting extrapulmonary lesions was evaluated in 12 patients with whom disseminated nonmeningeal coccidioidomycosis developed. Studies were performed with each radionuclide from 4 to 9 months after infection. Comparison of scintigraphy with radiography showed that eight of 14 osteolytic lesions identified by radiography were present on the bone and gallium scans; four were present only on the gallium scan, and two were undetected. Of 15 additional lesions present in both scanning procedures, eight were not present in matching roentgenograms and seven were in unstudied areas. Because nuclear scanning detected almost all lesions present in radiographs and demonstrated otherwise unrecognized lesions, scans should be performed in all patients in whom coccidioidal dissemination is suspected.

    2016-11-01

    China is a country that experiences a large number of disasters. The number of deaths caused by large-scale disasters and accidents in past 10 years is around 900,000. More than 92.8 percent of these deaths could be avoided if there were an effective pre-warning system deployed. Knowledge of the information dissemination characteristics of different information media taking into consideration governmental assistance (information published by a government) in disasters in urban areas, plays a critical role in increasing response time and reducing the number of deaths and economic losses. In this paper we have developed a comprehensive information dissemination model to optimize efficiency of pre-warning mechanics. This model also can be used for disseminating information for evacuees making real-time evacuation plans. We analyzed every single information dissemination models for pre-warning in disasters by considering 14 media: short message service (SMS), phone, television, radio, news portals, Wechat, microblogs, email, newspapers, loudspeaker vehicles, loudspeakers, oral communication, and passive information acquisition via visual and auditory senses. Since governmental assistance is very useful in a disaster, we calculated the sensitivity of governmental assistance ratio. The results provide useful references for information dissemination during disasters in urban areas.

    There were only a few reports of mercury on pulmonary artery. However, there is no data on surgery related mercury dissemination. The objective of the present article is to describe one case of postoperative injected mercury dissemination. A 19-year-old man presented severe neck pain including meningeal irritation sign and abdominal pain after injection of mercury for the purpose of suicide. Radiologic study showed injected mercury in the neck involving high cervical epidural space and subcutaneous layer of abdomen. Partial hemilaminectomy and open mercury evacuation of spinal canal was performed. For the removal of abdominal subcutaneous mercury, C-arm guided needle aspiration was done. After surgery, radiologic study showed disseminated mercury in the lung, heart, skull base and low spinal canal. Neck pain and abdominal pain were improved after surgery. During 1 month after surgery, there was no symptom of mercury intoxication except increased mercury concentration of urine, blood and hair. We assumed the bone work during surgery might have caused mercury dissemination. Therefore, we recommend minimal invasive surgical technique for removal of injected mercury. If open exposures are needed, cautious surgical technique to prohibit mercury dissemination is necessary and normal barrier should be protected to prevent the migration of mercury.

    Full Text Available Over the last three decades, China’s agriculture sector has been transformed from the traditional to modern practice through the effective deployment of Information and Communication Technologies (ICTs. Information processing and dissemination have played a critical role in this transformation process. Many studies in relation to agriculture information services have been conducted in China, but few of them have attempted to provide a comprehensive review and analysis of different information dissemination models and their applications. This paper aims to review and identify the ICT based information dissemination models in China and to share the knowledge and experience in applying emerging ICTs in disseminating agriculture information to farmers and farm communities to improve productivity and economic, social and environmental sustainability. The paper reviews and analyzes the development stages of China’s agricultural information dissemination systems and different mechanisms for agricultural information service development and operations. Seven ICT-based information dissemination models are identified and discussed. Success cases are presented. The findings provide a useful direction for researchers and practitioners in developing future ICT based information dissemination systems. It is hoped that this paper will also help other developing countries to learn from China’s experience and best practice in their endeavor of applying emerging ICTs in agriculture information dissemination and knowledge transfer.

    Full Text Available Disseminated tuberculosis is a common mode of presentation of tuberculosis in patients both with and without HIV/AIDS in India. However, primary multidrug resistance in disseminated tuberculosis involving only the extrapulmonary sites in an immunocompetent adult is rare. Here, we report a case of a 19-year-old man who had disseminated tuberculosis involving left pleura, pericardium, peritoneum and intraabdominal lymph nodes. He was initially taking WHO category I antituberculous drugs, but was not responding in spite of 5 months of chemotherapy. Culture of the pleural biopsy specimen grew Mycobacterium tuberculosis which was resistant to isoniazid and rifampicin. He was put on therapy for multidrug resistant tuberculosis,following 24 months of chemotherapyhe had an uneventful recovery.

    2011-10-01

    Full Text Available Pineal parenchymal tumors are rare. Of the three types of pineal parenchymal tumors, pineocytomas are the least aggressive and are not known to diffusely disseminate. In this paper, we report the successful treatment of a case of pineocytoma with diffuse leptomeningeal relapse following initial stereotactic radiotherapy. A 39-year-old female presented with headaches, balance impairment, urinary incontinence, and blunted affect. A pineal mass was discovered on magnetic resonance imaging (MRI. A diagnosis of pineocytoma was established with an endoscopic pineal gland biopsy, and the patient received stereotactic radiotherapy. Ten years later, she developed diffuse leptomeningeal dissemination. The patient was then successfully treated with craniospinal radiation therapy. Leptomeningeal spread may develop as late as 10 years after initial presentation of pineocytoma. Our case demonstrates the importance of long-term follow-up of patients with pineal parenchymal tumors following radiation therapy, and the efficacy of craniospinal radiation in the treatment of leptomeningeal dissemination.

    Full Text Available How to build a dissemination and communication strategy in a world where users have easy access to a deluge of data and information from various origins and where IT tools and design standards change so quickly that users behaviour and their expectations are continuously modified? The first challenge of Eurostat is clearly to know what users want: we know our different types of users but we have to identify how they get our data, what they do with our data, how they react to our outputs and which sort of new service they would like us to propose. Translating these needs into a visual dissemination is a new challenge undertaken by Eurostat through a new portal, new mobile apps and new info graphs and basic application as well as increasing the visibility on Google. The objective of this paper is to share Eurostat's experience in identifying user Leeds and to show how concretely this information has been visually disseminated.

    Full Text Available Cysticercosis is a common tropical disease and a common cause of seizures and neurological morbidity. Neurocysticercosis (NCC is the most common manifestation of the disease involving the central nervous system (CNS. One of the uncommon manifestations of cysticercosis is its disseminated form. The most commonly affected organs are the subcutaneous tissues, skeletal muscles, lungs, brain, eyes, liver, and occasionally the heart, thyroid, and pancreas but in widespread dissemination it can involve any organ in the body. We report here a case of a 35-year-old-female with disseminated cysticercosis (DCC. She attended our hospital with headache, fever, and symptoms of multiple palpable nodules. After the investigations, she was diagnosed with DCC involving the brain and subcutaneous tissues all over the body. Then she was successfully treated with albendazole and steroids.

    Invasive disseminated neonatal aspergillosis is an uncommon disease, with only scattered reports in literature in the last few years. Here we report on a 25-week gestational age, 730 g at birth preterm female infant who developed on day-of-life 10 multiple cutaneous exhulcerative lesions in her right arm, trunk and abdomen. Early recognition and diagnosis of these lesions as a due to cutaneous initial symptom of cutaneous disseminated aspergillosis, as well as prompt treatment with Liposomal amphotericin B + Itraconazole, secured successful recovery from the systemic infection. Skin lesions healed without any surgical treatment. The infant was discharged in good health. Long-term follow-up at three years of age revealed normality of all neurodevelopmental and cognitive parameters. To our knowledge, this is one of the very few cases of survival, free from sequelae, for a preterm infant affected by neonatal cutaneous disseminated aspergillosis.

    Full Text Available Abstract Introduction Several complications have been reported with inguinal hernias. Although hematuria and flank pain, either as the presentation or as a complication of inguinal hernia, are infrequent, this condition may lead to the development of obstructive uropathy, which can have diverse manifestations. Case presentation A 71-year-old Iranian man with Persian ethnicity presented with new onset episodes of gross hematuria and left-sided flank pain. A physical examination revealed a large and non-tender inguinal hernia on his left side. An initial workup included an abdominal ultrasound, an intravenous pyelogram and cystoscopy, which showed left hydronephrosis and a bulging on the left-side of his bladder wall. On further evaluation, computed tomography confirmed that his sigmoid colon was the source of the pressure effect on his bladder, resulting in hydroureteronephrosis and hematuria. No tumoral lesion was evident. Herniorrhaphy led to the resolution of his signs and symptoms. Conclusion Our case illustrates a rare presentation of inguinal hernia responsible for gross hematuria and unilateral hydronephrosis. Urologic signs and symptoms can be caused by the content of inguinal hernias. They can also present as complications of inguinal hernias.

    The purpose of this project is to carry out assessment on the effectiveness and performance of Gross Pollutant Traps (GPTs) stormwater quality control in the urban areas. The study aims to provide a management and planning tool for effective management of the gross pollutants in the urban areas specifically in River of Life (ROL) project. ROL project is a Malaysian Government initiative under the Economic Transformation Program. One of the program in the greater Klang Valley is to transform Klang River into a vibrant and livable waterfront by the year 2020. The main river in ROL catchment is Sungai Klang (upper catchment), with main tributaries Sungai Gombak, Sungai Batu, Sungai Jinjang, Sungai Keroh, Sungai Bunus, Sungai Ampang and Sungai Kerayong. This paper objective is to study the gross pollutant wet load at Sungai Kerayong 1 and Sungai Kerayong 2 which is located at the downstream location of the ROL project. The result shows that Sungai Kerayong 2 produced higher gross pollutant wet load (8025.33 kg/ha/yr) than Sungai Kerayong 1 (4695.12 kg/ha/yr). This could be due to high contributions amounts of gross pollutant traps from residential area, the degree of develop area, and also the location of the river itself related to climate and rainfall.

  12. Gross efficiency during rowing is not affected by stroke rate.

    2009-05-01

    It has been suggested that the optimal stroke rate in rowing is partly determined by the stroke-rate dependence of internal power losses. This should be reflected in a stroke-rate dependency of gross efficiency (e(gross)). The purpose of this study was to investigate if e(gross) is affected by stroke rate. A second aim was to determine whether internal power losses can be estimated by the negative power output during the stroke cycle (P(negative)). Seventeen well-trained female rowers participated in this study. They rowed three trials on a modified rowing ergometer on slides at a submaximal intensity, with a respiratory exchange ratio of 1 or close to 1. Stroke rates were 28, 34, and 40 strokes per minute. The trials were fully randomized. Power transfer to the flywheel was kept constant whereas e(gross) was determined during each trial. No significant differences in e(gross) were found between conditions. This finding suggests that in rowing internal power losses are not influenced by stroke rate. Furthermore, although P(negative) increased at increasing stroke rate (P measure to estimate internal power losses. This study shows that within the range of stroke rates applied in competitive rowing, internal power losses are unrelated to rowing cycle frequency.

    2017-04-01

    Dissemination and Exploitation are essential parts of public funded projects. In Horizon 2020 a plan for the exploitation and dissemination of results (PEDR) is a requirement. The plan should contain a clear vision on the objectives of the project in relation to actions for dissemination and potential exploitation of the project results. The actions follow the basic idea to spread the knowledge and results gathered within the project and face the challenge of how to bring the results into potentially relevant policy circle and how they impact the market. The plan follows the purpose to assess the impact of the project and to address various target groups who are interested in the project results. Simply put, dissemination concentrates on the transfer of knowledge and exploitation on the commercialization of the project. Beyond the question of the measurability of project`s impact, strategies within science marketing can serve purposes beyond internal and external communication. Accordingly, project managers are facing the challenge to implement a dissemination and exploitation strategy that ideally supports the identification of all partners with the project and matches the current discourse of the project`s content within the society, politics and economy. A consolidated plan might unite all projects partners under a central idea and supports the identification with the project beyond the individual research questions. Which applications, strategies and methods can be used to bring forward a PEDR that accompanies a project successfully and allows a comprehensive assessment of the project afterwards? Which hurdles might project managers experience in the dissemination process and which tasks should be fulfilled by the project manager?

    MRI shows promise as a prognostic tool for clinical findings such as gross motor function in children with cerebral palsy(CP), however the relationship with communication skills requires exploration. To examine the relationship between the type and severity of brain lesion on MRI and communication skills in children with CP. 131 children with CP (73 males(56%)), mean corrected age(SD) 28(5) months, Gross Motor Functional Classification System distribution: I=57(44%), II=14(11%), III=19(14%), IV=17(13%), V=24(18%). Children were assessed on the Communication and Symbolic Behavioral Scales Developmental Profile (CSBS-DP) Infant-Toddler Checklist. Structural MRI was analysed with reference to type and semi-quantitative assessment of the severity of brain lesion. Children were classified for motor type, distribution and GMFCS. The relationships between type/severity of brain lesion and communication ability were analysed using multivariable tobit regression. Children with periventricular white matter lesions had better speech than children with cortical/deep grey matter lesions (β=-2.6, 95%CI=-5.0, -0.2, p=0.04). Brain lesion severity on the semi-quantitative scale was related to overall communication skills (β=-0.9, 95%CI=-1.4, -0.5, p1 SD below children with periventricular white matter lesions. Children with more severe brain lesions on MRI had poorer overall communication skills. Children with CP born at term had poorer communication than those born prematurely and were more likely to have cortical and deep grey matter lesions. Gross motor function better accounted for overall communication skills than the type of brain lesion or brain lesion severity. Copyright © 2016. Published by Elsevier Ltd.

    Full Text Available Ghost cells have been a controversy for a long time. Ghost cell is a swollen/enlarged epithelial cell with eosnophilic cytoplasm, but without a nucleus. In routine H and E staining these cells give a shadowy appearance. Hence these cells are also called as shadow cells or translucent cells. The appearance of these cells varies from lesion to lesion involving odontogenic and nonodontogenic lesions. This article review about the origin, nature and significance of ghost cells in different neoplasms.

    ABSTRACT Cladosporium carpophilum, the causal agent of peach scab, overwinters in lesions on 1-year-old twigs, from which conidia infect the developing fruit during spring and early summer. Twig lesions constitute the sole source of initial inoculum; therefore, the mode of dissemination of conidia from such lesions to the fruit is of considerable interest. In a 4-year study, we determined the relative importance of air- versus water-borne conidia and their interaction with different fruit wetness sources (splash, twig runoff, and dew) in a peach orchard with areas that had been treated or not treated with fungicide the previous year. The rareness of scab twig lesions in the previously sprayed trees implied that fruit infection in these trees would occur primarily by airborne conidia from unsprayed trees nearby (located within the same tree row or the adjacent row). In the unsprayed areas, additional infections could occur by short-distance waterborne dissemination of conidia from locally abundant twig lesions via splashing or runoff. Beginning at calyx fall, individual fruit were protected from splash by rain shields, protected from runoff by cotton wicks placed proximal to the peduncle, or left untreated. Rain shields were adjustable, allowing rain or dew to be excluded selectively. Various combinations of the shield and wick treatments were implemented in the previously sprayed and unsprayed areas, and statistical comparison of fruit scab severity between individual treatments by linear contrasts allowed us to untangle the relative contributions of the various sources of inoculum and fruit wetness. Results showed that aerial dissemination of conidia contributed little to fruit scab development, even in the presence of fruit surface wetness caused by splashing, runoff, or dew. In contrast, waterborne conidia contributed considerably and significantly (P disease development. This was due primarily to the importance of splash in disseminating conidia from twig

    Full Text Available Problem statement: The anatomy of the gross intestine and its mesentery of the capybara (Hydrochoerus hydrochaeris have not been described completely. Approach: In the present study, eight adult capybaras were studied using gross dissection. Results: The cecum was the largest part of the intestine and was divided into base, body and apex. The cecocolic fold joined the cecum to the full extent of the proximal loop of ascending colon. The ascending colon was divided into two ansae, one proximal and one distal or spiral. The distal ansa had a spiral arrangement and was placed cranially to the right, covered ventrally by the apex of the cecum. This ansa had a centripetal gyrus to the left, a central flexure and a centrifugal gyrus turning to the right that was continuous with the transverse colon in the right colic flexure. Conclusion: The gross intestine of the capybara was different to other previously studied rodents.

    The objective of this study was to determine the gross alpha and gross beta activity concentrations from the different soil types found in the Kinta District, Perak, Malaysia. A total of 128 soil samples were collected and their dose rates were measured 1 m above the ground. Gross alpha and gross beta activity measurements were carried out using gas flow proportional counter, Tennelec Series 5 LB5500 Automatic Low Background Counting System. The alpha activity concentration ranged from 15 to 9634 Bq kg(-1) with a mean value of 1558±121 Bq kg(-1). The beta activity concentration ranged from 142 to 6173 Bq kg(-1) with a mean value of 1112±32 Bq kg(-1). High alpha and beta activity concentrations are from the same soil type. The results of the analysis show a strong correlation between the gross alpha activity concentration and dose rate (R = 0.92). The data obtained can be used as a database for each soil type.

  2. Ludwik Gross, Sarah Stewart, and the 1950s discoveries of Gross murine leukemia virus and polyoma virus.

    Morgan, Gregory J

    2014-12-01

    The Polish-American scientist Ludwik Gross made two important discoveries in the early 1950s. He showed that two viruses - murine leukemia virus and parotid tumor virus - could cause cancer when they were injected into susceptible animals. At first, Gross's discoveries were greeted with skepticism: it seemed implausible that viruses could cause a disease as complex as cancer. Inspired by Gross's initial experiments, similar results were obtained by Sarah Stewart and Bernice Eddy who later renamed the parotid tumor virus SE polyoma virus after finding it could cause many different types of tumors in mice, hamsters, and rats. Eventually the "SE" was dropped and virologists adopted the name "polyoma virus." After Gross's work was published, additional viruses capable of causing solid tumors or blood-borne tumors in mice were described by Arnold Graffi, Charlotte Friend, John Moloney and others. By 1961, sufficient data had been accumulated for Gross to confidently publish an extensive monograph--Oncogenic Viruses--the first history of tumor virology, which became a standard reference work and marked the emergence of tumor virology as a distinct, legitimate field of study.

    We confirm earlier hints that the conventional phase diagram of the discrete chiral Gross-Neveu model in the large N limit is deficient at non-zero chemical potential. We present the corrected phase diagram constructed in mean field theory. It has three different phases, including a kink-antikink crystal phase. All transitions are second order. The driving mechanism for the new structure of baryonic matter in the Gross-Neveu model is an Overhauser type instability with gap formation at the Fermi surface.

    Localized, myocardial toxoplasmosis contributed to the death of a female ring-tailed lemur (Lemur catta) 1 week after the delivery of 4 stillborn offspring with disseminated toxoplasmosis; the diagnosis was obtained by histopathology and immunohistochemistry in all 5 lemurs. Varying degrees of placentitis and placental edema with intralesional Toxoplasma gondii immunolabeling were observed in the 3 available placentas. The dam had severe myocarditis, and T. gondii antigen was only detected in the myocardial lesions. Disseminated toxoplasmosis with mild encephalitis was noted in all 4 fetuses, and 2 of the fetuses had mild acute multifocal hepatic necrosis. Fetal death was attributed to placental insufficiency with subsequent hypoxia and amniotic fluid aspiration.

    2008-01-01

    The article provides a review and considers how the diffusion of innovations Research paradigm has changed, and offers suggestions for the further development of this theory of social change. Main emphases of diffusion Research studies are compared over time, with special attention to applications of diffusion theory-based concepts as types of dissemination science. A considerable degree of paradigmatic evolution is observed. The classical diffusion model focused on adopter innovativeness, individuals as the locus of decision, communication channels, and adoption as the primary outcome measures in post hoc observational study designs. The diffusion systems in question were centralized, with fidelity of implementation often assumed. Current dissemination Research and practice is better characterized by tests of interventions that operationalize one or more diffusion theory-based concepts and concepts from other change approaches, involve complex organizations as the units of adoption, and focus on implementation issues. Foment characterizes dissemination and implementation Research, Reflecting both its interdisciplinary Roots and the imperative of spreading evidence-based innovations as a basis for a new paradigm of translational studies of dissemination science.

    2001-08-01

    The goal of the FAIR-INNOVATION dissemination project (FLAIR-FLOW 3) (1997-2000) was to disseminate R&D results from the EU FAIR programme to small and medium-sized food enterprises (SMEs), health professionals (HPs) and consumer groups (CGs) in 19 European countries. The dissemination routes were: (i) one-page technical documents on research results; (ii) their reproduction on the internet; (iii) their reproduction in journals Europe-wide; (iv) workshops on results from EU-supported food research programmes; and (v) lectures and poster presentations by FLAIR-FLOW network personnel. Of the 135 one-pagers produced, 62% were targeted at SMEs, 18% at HPs and 5% at CGs. The remaining 15% were on food safety and were common to the three target groups. There were 1047 publications arising from one-pages in trade journals, and over 8000 requests (paper route) were received for follow-up information. These were in addition to 240 k downloads from the FLAIR-FLOW 3 web site (www.flair-flow.com). Initiatives for HPs included specially collated versions of the one-pagers for major conferences, 20 focused workshops, and interaction with the European Federation of Associations of Dieticians. Currently, dissemination is continuing through FLAIR-FLOW 4 (2001-2003) in 24 countries. FLAIR-FLOW 4 is co-ordinated by M. Jean François Quillien from INRA-CRIAA (FR) at criaa@rennes.inra.fr.

    Juvenile disseminated periventricular calcifications may occur in tuberous sclerosis, toxoplasmosis, cytomegaly, and in tuberculous meningitis. Cysticercosis, by contrast, does not result in corresponding intracerebral foci until an older age. Differential diagnosis is no problem if clinical findings are typical (tuberous sclerosis) or if serological verification is positive. However, any unclear clinical diagnosis can often be secured by CT.

    2016-06-01

    A 66-year-old woman with refractory angioimmunoblastic T-cell lymphoma underwent cord blood transplantation. Prior to transplantation, a serological test for Toxoplasma gondii-specific IgG antibodies was positive. On day 96, she exhibited fever and dry cough. Chest CT showed diffuse centrilobular ground glass opacities in both lungs. The reactivation of T. gondii was identified by the presence of parasite DNA in peripheral blood and bronchoalveolar lavage fluid. Moreover, brain MRI revealed a space occupying lesion in the right occipital lobe. Therefore, disseminated toxoplasmosis was diagnosed. She received pyrimethamine and sulfadiazine from day 99. The lung and brain lesions both showed improvement but the PCR assay for T. gondii DNA in peripheral blood was positive on day 133. On day 146, she developed blurred vision and reduced visual acuity, and a tentative diagnosis of toxoplasmic retinochoroiditis was made based on ophthalmic examination results. As agranulocytosis developed on day 158, we decided to discontinue pyrimethamine and sulfadiazine and the treatment was thus switched to atovaquone. Moreover, we added spiramycin to atovaquone therapy from day 174, and her ocular condition gradually improved. In general, the prognosis of disseminated toxoplasmosis after hematopoietic stem cell transplantation (HSCT) is extremely poor. However, early diagnosis and treatment may contribute to improvement of the fundamentally dismal prognosis of disseminated toxoplasmosis after HSCT.

    Introduction The prevalence of oropharyngeal dysphagia (OPD) in children with cerebral palsy (CP) is estimated to be between 19% and 99%. OPD can impact on children's growth, nutrition and overall health. Despite the growing recognition of the extent and significance of health issues relating to OPD in children with CP, lack of knowledge of its profile in this subpopulation remains. This study aims to investigate the relationship between OPD, attainment of gross motor skills, growth and nutritional status in young children with CP at and between two crucial age points, 18–24 and 36 months, corrected age. Methods and analysis This prospective longitudinal population-based study aims to recruit a total of 200 children with CP born in Queensland, Australia between 1 September 2006 and 31 December 2009 (60 per birth-year). Outcomes include clinically assessed OPD (Schedule for Oral Motor Assessment, Dysphagia Disorders Survey, Pre-Speech Assessment Scale, signs suggestive of pharyngeal phase impairment, Thomas-Stonell and Greenberg Saliva Severity Scale), parent-reported OPD on a feeding questionnaire, gross motor skills (Gross Motor Function Measure, Gross Motor Function Classification System and motor type), growth and nutritional status (linear growth and body composition) and dietary intake (3 day food record). The strength of relationship between outcome and exposure variables will be analysed using regression modelling with ORs and relative risk ratios. Ethics and dissemination This protocol describes a study that provides the first large population-based study of OPD in a representative sample of preschool children with CP, using direct clinical assessment. Ethics has been obtained through the University of Queensland Medical Research Ethics Committee, the Children's Health Services District Ethics Committee, and at other regional and organisational ethics committees. Results are planned to be disseminated in six papers submitted to peer reviewed journals

    Mast cell tumors are found in most organs and tissues with variable biologic behavior in dogs. This case illustrates the clinical and magnetic resonance imaging (MRI) findings in a dog with disseminated mast cell tumor infiltrating the sphenoid bones. A 6-year-old male neutered Greyhound presented with a 3-day history of acute onset of blindness. General physical examination was normal. Neurological examination revealed mildly disorientated mental status, absent menace response in both eyes, bilaterally decreased vestibulo-oculocephalic reflexes and absent direct and consensual pupillary light reflex in both eyes. An electroretinogram indicated normal retinal function in both eyes. A lesion involving the middle and rostral cranial fossa was suspected. Hematology and serum biochemistry were normal except decreased urea (1.2 mmol/L). MRI of the head revealed heterogeneous signal intensity of the sphenoid bones on T2-weighted images and loss of their normal internal architecture. Cerebrospinal fluid analysis was normal. Abdominal ultrasound revealed hepatosplenomegaly and mesenteric lymphadenopathy. Fine needle aspirates were taken from the jejunal lymph nodes and the spleen. Results were consistent with disseminated mast cell tumor. The owner declined any treatment and the dog was euthanatized. Postmortem examination confirmed disseminated mast cell tumor affecting multiple organs, including the sphenoid bones. To our knowledge, this is the first case describing MRI features of disseminated mast cell tumor affecting the sphenoid bones and causing acute onset of blindness in a dog.

    The simultaneous measurements of gross alpha and beta activities is one of the simplest radioanalytical technique used as a method for screening samples of both high and low activities of alpha and beta emitting radionuclides in environmental and bioassay samples. Such measurements are of great interest from both a radiological, waste disposal viewpoint, and to establish a trend of radioactivity based on long term monitoring. At the WIPP (Waste Isolation Pilot Plant) site, unfiltered exhaust air from the underground repository is the most important effluent. As part of its monitoring program, the particulates from WIPP exhaust air are collected everyday at a location typically called the Fixed Air Sampler (FAS) site or Station A, this site is located at the release point for aerosol effluents from the underground to the environment. The measurements of gross alpha and beta activity on air filter samples were performed using an ultra low level counter, PIC-MPC 9604-{alpha}/{beta}, from Protean Instrument Corporation. The high sensitivity of the gross alpha and beta instrument enables detection of low value activity from the air filters. In 2009, the values of gross alpha and beta activity concentrations ranged from Simultaneous measurements of gross alpha and gross beta activities in the particulates from WIPP exhaust air were performed. > Ultra low level counter, PIC-MPC 9604-{alpha}/{beta} counter was used for the measurements. > Values of gross alpha activity concentrations ranged from Values of gross beta activity concentrations ranged from

  15. Dissemination Matters: Influences of Dissemination Activities on User Types in an Online Educational Community

    Min Yuan

    2014-09-01

    Full Text Available Emerging online educational communities provide spaces for teachers to find resources, create instructional activities, and share these activities with others. Within these online communities, individual users’ activities may vary widely, and thus different user types can be identified. In addition, users’ patterns of activities in online communities are dynamic, and further can be affected by dissemination activities. Through analyzing usage analytics in an online teacher community called the Instructional Architect, this study explores the influences of dissemination activities on the usage patterns of different user types. Results show that dissemination activities can play an important role in encouraging users’ active participation, while the absence of dissemination activities can further increase participation inequality.

    Marker, David R; Juluru, Krishna; Long, Chris; Magid, Donna

    2012-01-01

    Current generations of graduate students have been immersed in technology from their early school years and have high expectations regarding digital resources. To better meet the expectations of Gross Anatomy students at our institution, electronic radiology teaching files for first-year coursework were organized into a web site. The web site was custom designed to provide material that directly correlated to the Gross Anatomy dissection and lectures. Quick links provided sets of images grouped by anatomic location. Additionally, Lab and Study Companions provided specific material for the students to review prior to and after lectures and gross dissections. Student opinions of this education resource were compared to student opinions of the prior year's digital teaching files. The new content was ranked as more user friendly (3.1 points versus 2.3 points) and more useful for learning anatomy (3.3 points versus 2.6 points). Many students reported that using the web portal was critical in helping them to better understand relationships of anatomical structures. These findings suggest that a well-organized web portal can provide a user-friendly, valuable educational resource for medical students who are studying Gross Anatomy.

    2006-01-01

    Samuel David Gross (1805-1884) represented the most notable surgeon of his generation and was honored with the title of "The Nestor of American Surgeon" by surgeon biographer Isaac Minis Hays. Of Pennsylvania Dutch stock, he was born on the family farm near Easton, Pennsylvania. He attended Wilkebarré Academy and Lawrenceville High School, noted private institutions of the day. He apprenticed under Doctor Joseph K. Swift of Easton and later with Professor George McClellan while in Philadelphia. In 1828, he graduated from Jefferson Medical College and remained for a short time in Philadelphia. Professor Gross focused his professional pursuits in the cities of Easton (1830-1833), Cincinnati (1833-1840), Louisville (1840-1856), and Philadelphia (1856-1882). He retired from Jefferson Medical College two years before his death in 1884. Samuel D. Gross' contributions to surgery were numerous and diverse. He was recognized as a prolific author of classic texts of pathology, surgery, and history, an educator, a leader, a surgical researcher, and a pioneer surgeon practitioner. His influence in national affairs was immense, and his recognition as a respected surgeon was unmatched. He remains the most distinguished surgeon of his times. History values him as a hard working, honest, highly competent, and committed individual. His capacity for work and his dedication to a single cause were unrivaled. Doctor Gross integrated the best that surgery could give to future generations of surgical professionals.

    2012-01-01

    Full Text Available Current generations of graduate students have been immersed in technology from their early school years and have high expectations regarding digital resources. To better meet the expectations of Gross Anatomy students at our institution, electronic radiology teaching files for first-year coursework were organized into a web site. The web site was custom designed to provide material that directly correlated to the Gross Anatomy dissection and lectures. Quick links provided sets of images grouped by anatomic location. Additionally, Lab and Study Companions provided specific material for the students to review prior to and after lectures and gross dissections. Student opinions of this education resource were compared to student opinions of the prior year’s digital teaching files. The new content was ranked as more user friendly (3.1 points versus 2.3 points and more useful for learning anatomy (3.3 points versus 2.6 points. Many students reported that using the web portal was critical in helping them to better understand relationships of anatomical structures. These findings suggest that a well-organized web portal can provide a user-friendly, valuable educational resource for medical students who are studying Gross Anatomy.

  2. Intraosseous osteolytic lesions

    Energy Technology Data Exchange (ETDEWEB)

    Adler, C.P.; Wenz, W.

    1981-10-01

    Any pathological damage occurring in a bone will produce either an osteolytic or osteosclerotic lesion which can be seen in the macroscopic specimen as well as in the roentgenogram. Various bone lesions may lead to local destructions of the bone. An osteoma or osteoplastic osteosarcoma produces an osteosclerotic lesion showing a dense mass in the roentgenogram; a chondroblastoma or an osteoclastoma, on the other hand, induces an osteolytic focal lesion. This paper presents examples of different osteolytic lesions of the humerus. An osteolytic lesion seen in the roentgenogram may be either produced by an underlying non-ossifying fibroma of the bone, by fibrous dysplasia, osteomyelitis or Ewing's sarcoma. Differential diagnostic considerations based on the radiological picture include eosinophilic bone granuloma, juvenile or aneurysmal bone cyst, multiple myeloma or bone metastases. Serious differential diagnostic problems may be involved in case of osteolytic lesions occurring in the humerus. Cases of this type involving complications have been reported and include the presence of an teleangiectatic osteosarcoma as well as that of a hemangiosarcoma of the bone.

    2008-03-01

    A 14-month-old heifer with a 17-day history of unresponsive bloody diarrhea was necropsied. There were focal, pink-red erosions of the nares and hard palate; ulcers and fissures of the tongue; and multiple ulcerative lesions of the alimentary canal. Interdigital skin of both rear limbs was ulcerated and bleeding; and the margins of the vulva contained punctiform red ulcers. The gross lesions were consistent with mucosal disease. Histopathology and laboratory testing ruled out rinderpest, foot-and-mouth disease, and vesicular stomatitis, and identified bovine virus diarrhea virus to be the cause of this disease. Lesions of the vulva similar to those seen in some stages of infectious pustular vulvovaginitis were negative for bovine herpesvirus-1 and tested positive for bovine viral diarrhea virus antigen by immunohistochemistry.

    Taylor, Peter; Smith, Charlie E; Blair, Marilyn J

    2009-03-01

    Polycystic lesions have been reported from the kidney and liver of many different fish species and are attributed to pollution and genetic anomalies. In June 2002, eggs and milt were collected from two female and five male white sturgeon Acipenser transmontanus below Bonneville Dam on the Columbia River. Fertilized eggs were hatched at the Abernathy Fish Technology Center in Longview, Washington, and 20,000 juveniles were raised for approximately 1 year before release into the wild. Just before release, 12,000 juveniles were scute-marked, during which it was noticed that about 30 fish had distended abdomens. Gross necropsy revealed a large, jellylike mass in the peritoneal cavity. Histopathological examination of four fish showed that this growth was a polycystic lesion of liver tissue. This is the first report of this type of lesion in white sturgeon and is presumed to be the product of a genetic anomaly.

    2013-07-01

    We report disseminated cysticercosis concurrent with taeniasis in a 31-year-old male Japanese, who had visited India three times and stayed for 1 month each time during the previous 1 year. The patient presented increasing numbers of subcutaneous nodules and expelled proglottids, although numerous cysts were also found in the brain in imaging findings, though no neurological symptoms were observed. Histopathological and serological findings strongly indicated cysticercosis. We found taeniid eggs in his stool by microscopic examination and revealed them as the Indian haplotype of Taenia solium by mitochondrial DNA analysis. We concluded that disseminated cysticercosis was caused by the secondary autoinfection with eggs released from the tapeworm carrier himself. After confirming the absence of adult worms in the intestine by copro-polymerase chain reaction, the patient was successfully treated with albendazole at a dose of 15 mg/kg/day for 28 days. Subcutaneous and intracranial lesions had completely disappeared by the end of the treatment period.

    2004-01-01

    Chronic disseminated histiocytosis is a systemic disorder resulting from tumor proliferation of Langerhans-type histiocytic cells. The etiology and pathogenesis are not fully clear, though the clinical manifestations are the result of the accumulation and infiltration of these types of cells in organs and tissues. The present study reports 10 patients (6 boys and 4 girls) with chronic disseminated histiocytosis. The patient age at onset of the disease varied from 4 months to 3.2 years (mean 1.7 years). All patients had oral lesions, and in 5 cases these were the first manifestation of the disease. The most frequent alterations were gingival bleeding (7 cases), aphthae measuring over 1 cm in diameter (6 cases), maxillary osteolytic lesions (6 cases), tooth loss due to expulsive folliculitis (5 cases), oral candidiasis (4 cases), orofacial swelling (3 cases), aphthae measuring under 1 cm in diameter (3 cases), and nonspecific oral pain (2 cases). All the oral lesions disappeared with the treatments prescribed, though some patients developed new outbreaks and exacerbations of the disease.

    This study focuses on dissemination of innovations through external entrepreneurs. The innovations studied are developed at the European Organization for Nuclear Research (CERN) and commercialized by entrepreneurs establishing spin-off companies on the outside of the Organization. The objective of this study is to provide knowledge to facilitate future external entrepreneurs to increase dissemination of CERN technologies. The research questions looks at the timeline from preparations for creating the spin-off company, until having a product for commercialization in the market. A qualitative cross case investigation was conducted to assess the experiences of four spin-off companies. A framework was created to structure the discussion by finding and categorizing impeding- and success factors seen from the entrepreneurs point of view. The findings where structured in three phases respectively, the time before starting the company, the beginning of the company and the final development before selling products. Th...

    Many survivors of the tsunami that occurred following the Great East Japan Earthquake on March 11, 2011, contracted a systemic disorder called "tsunami lung," a series of severe systemic infections following aspiration pneumonia caused by near drowning in the tsunami. Generally, the cause of aspiration pneumonia is polymicrobial, including fungi and aerobic and anaerobic bacteria, but Aspergillus infection is rarely reported. Here we report a case of tsunami lung complicated by disseminated aspergillosis, as diagnosed during autopsy.

    2012-01-01

    Full Text Available Histoplasmosis, a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum var capsulatum and Histoplasma capsulatum var duboisii is endemic to many parts of the world. The clinical manifestations range from acute or chronic pulmonary infection to a progressive disseminated disease. After initial exposure to the fungus, the infection is self-limited and restricted to the lungs in 99% of healthy individuals. The remaining 1%, however, progress to either disseminated or chronic disease involving the lungs, liver, spleen, lymph nodes, bone marrow or rarely, the skin and mucous membranes. Mucocutaneous histoplasmosis is frequently reported in patients with acquired immune deficiency syndrome (AIDS, but it is rare in immunocompetent hosts. A 60-year-old male presented with asymptomatic swelling of the hard palate and crusted papules and nodules over the extremities, face and trunk. Clinically, the diagnoses of cutaneous cryptococcosis versus histoplasmosis was considered in this patient. A chest X-ray revealed hilar lymphadenopathy. Enzyme-linked immunosorbent assay (ELISA for human immunodeficiency virus (HIV was nonreactive. Skin biopsy revealed multiple tiny intracellular round yeast forms with a halo in the mid-dermis. Culture of the skin biopsy in Sabouraud′s dextrose agar showed colonies of Histoplasma capsulatum. Despite an investigation including no evidence of underlying immunosuppression was found, he was started on IV amphotericin-B (0.5 mg/kg/day. However, the patient succumbed to his disease 2 days after presentation. We report a rare case of disseminated cutaneous histoplasmosis in an immunocompetent individual.

  2. Use of UDP for efficient imagery dissemination

    In the defence organization, imagery represents an important information source for users in the tactical, operational and strategic environments. Its wider dissemination may rely on deployed communication networks that are often unstable with high bit error rates and outages. This paper presents efficient techniques for imagery dissemination using the user datagram protocol (UDP). The use of UDP is compared with the popular transmission control protocol and shown to be superior in performance for error prone IP networks. We have employed a wavelet based coder producing an embedded bit-stream. The packetization of the bit-stream is investigated and we show that it is better to tile an image into independent embedded bit-streams when the network performance is poor. Variable-size tiling is compared with, and shown to be superior to, a fixed-size tiling approach. Selective re-transmission of lost packets is implemented for efficient imagery dissemination using UDP. The selective re- transmission scheme is a function of network bandwidth, delay times, error rates and the significance of the packet.

    Directory of Open Access Journals (Sweden)

    Jiro Akimoto

    2014-01-01

    Full Text Available Background: Two patients who had received a total resection of cerebellar hemangioblastoma developed cerebrospinal fluid dissemination during a long-term follow-up period. We present this rare disease with discussion based on the literature. Case Description: The patients were two women aged 45 and 57 years. In the cerebellar hemisphere, one patient had cystic hemangioblastoma of mural nodule type and the other had solid type. Both the patients successfully underwent total resection by craniotomy. They presented no mutations in the von Hippel-Lindau disease (VHL gene or lesions in the other organs. One patient developed local recurrence 38 months after the initial surgery, and received stereotactic radiosurgery. Three spinal cord tumors developed 91 months later, and the tumors were disseminated to the entire cerebrospinal cavity 107 months later. The other patient developed hydrocephalus 53 months after the initial surgery with tumor tissues disseminated in the intracranial subarachnoid space. The conditions of the two patients gradually aggravated despite treatment with ventriculo-peritoneal shunt and irradiation to the whole brain and whole spinal cord. Conclusion: Cerebrospinal fluid dissemination of cerebellar hemangioblastoma was found dominantly in non-VHL patients. The diagnosis was made 10 years after the initial surgery. Irradiation therapy was performed, but the patients died about 2 years after the diagnosis was given. Molecular targeted therapies including vascular proliferation suppression have been attempted lately, but no effective therapy has been established. Early diagnosis of dissemination as well as combination of aggressive excision and stereotactic radiosurgery are considered to be appropriate for current interventions.

  6. Blunt Renal Trauma in a Pre-Existing Renal Lesion

    G.V. Soundra Pandyan

    2006-01-01

    Full Text Available A 70-year-old male presented with direct trauma to his loin with gross hematuria, as an isolated case of blunt renal trauma (BRT due to a traffic accident. A pre-existing renal lesion (PERL was strongly suspected by his past history of gross macroscopic hematuria and monotrauma to the kidney without other associated injuries. Spiral CT scan with contrast and a retrograde pyelogram (RGP confirmed an occult complex renal cyst. The gold standard of CT diagnosis in this situation is stressed. Computed tomography is particularly useful in evaluating traumatic injuries to kidneys with pre-existing abnormalities. The decision on the initial course of conservative management, ureteral retrograde stenting to drain extravasation, and its final outcome are discussed. Radical nephroureterectomy was carried out by a transperitoneal approach with an early vascular control of the renal pedicle. A brief review of recent literature has been undertaken.

    We introduce the large portfolio selection using gross-exposure constraints. We show that with gross-exposure constraint the empirically selected optimal portfolios based on estimated covariance matrices have similar performance to the theoretical optimal ones and there is no error accumulation effect from estimation of vast covariance matrices. This gives theoretical justification to the empirical results in Jagannathan and Ma (2003). We also show that the no-short-sale portfolio can be improved by allowing some short positions. The applications to portfolio selection, tracking, and improvements are also addressed. The utility of our new approach is illustrated by simulation and empirical studies on the 100 Fama-French industrial portfolios and the 600 stocks randomly selected from Russell 3000. PMID:23293404

    Guarneri, Italo

    2017-03-01

    The Gross-Pitaevski map is a discrete time, split-operator version of the Gross-Pitaevski dynamics in the circle, for which exponential instability has been recently reported. Here it is studied as a classical dynamical system in its own right. A systematic analysis of Lyapunov exponents exposes strongly chaotic behavior. Exponential growth of energy is then shown to be a direct consequence of rotational invariance and for stationary solutions the full spectrum of Lyapunov exponents is analytically computed. The present analysis includes the "resonant" case, when the free rotation period is commensurate to 2 π , and the map has countably many constants of the motion. Except for lowest-order resonances, this case exhibits an integrable-chaotic transition.

    Smith, D. E.; Vonbun, F. O.

    1973-01-01

    A plan was developed during 1971 to determine gross tectonic plate motions along the San Andreas Fault System in California. Knowledge of the gross motion along the total fault system is an essential component in the construction of realistic deformation models of fault regions. Such mathematical models will be used in the future for studies which will eventually lead to prediction of major earthquakes. The main purpose of the experiment described is the determination of the relative velocity of the North American and the Pacific Plates. This motion being so extremely small, cannot be measured directly but can be deduced from distance measurements between points on opposite sites of the plate boundary taken over a number of years.

This research analyzes the role of globalization on GDP inASEAN-5 by estimating panel data. It uses a fixed effect approach to accommodate various characteristicsin the countries. To accommodate such variation, it assumes that the intercepts variesacross these countries, while the slopes remain similar. Based on the estimation result, it suggeststhat net export and foreign direct investment represent the globalization process. Both have positiveand significant influences on GDP in the corresponding countries.Keywords: Globalization, international trade, foreign direct investment, gross domestic productJEL classification numbers: E01, F51, F43

    2015-09-01

    Full Text Available The aim of this study was to predict gross feed efficiency of Italian Holstein Friesian bulls selected for production, functional and type traits. A total of 12,238 bulls, from the April 2015 genetic evaluation, were used. Predicted daily gross feed efficiency (pFE was obtained as ratio between milk yield (MY and predicted dry matter intake (pDMI. Phenotypic trend for MY, predicted body weight (pBW and pFE were calculated by the bull birth year. The results suggest that pFE can be successfully selected to increase profitability of dairy cattle using the current milk recording system. Direct measurements on DMI should be considered to confirm results of pFE obtained in the present study.

    Full Text Available Alveolar hydatid disease or alveolar echinococcosis is a disease of the parasite Echinococcus multilocularis that is potentially fatal if left untreated. It primarily involves the liver but can be disseminated to other organs like the lungs and the brain by hematogenous route. Multiorgan involvement and the aggressive appearance of lesions make alveolar hydatid disease easy to confuse with a metastatic malignancy. For this reason, histopathological confirmation is essential for definite diagnosis. We present the imaging features of this disease in two patients in order to emphasize that these lesions can be easily misdiagnosed as malignancies.

    We report four disseminated cutaneous leishmaniasis(DCL) cases referred to leishmaniasis laboratory at the School of Public Health, Tehran University of Medical Sciences with multiple nodular, ulcerative and crusted lesions extended on the face, trunk, and extremities. None of the patients had any complication and historical involvement in their immunological system conditions that suggest as the criteria for DCL. Direct smears of ulcers were positive for Leishmania parasite. The parasite was isolated from the active lesions and identified as Leishmania major (L. major) using PCR-RFLP assay and sequencing analysis.

    A 62-year-old white man with a 10-year history of treatment-refractory Sweet's syndrome was admitted to the hospital with the onset of purpuric lesions. Methylprednisolone and infliximab were administered. Our patient developed disseminated Nocardia infection and eventually succumbed. Opportunistic infections such as Nocardia have been associated with infliximab and other tumour necrosis factor (TNF)-α inhibitors. The astute clinician should be aware of the risk of rare opportunistic infections, particularly in patients on TNF-α inhibitors and systemic corticosteroids.

    Naturally occurring Sarcocystis neurona infection in a ferret (Mustela putorius furo) with rhinitis and disseminated disease are described for the first time. The ferret exhibited severe rhinitis with intra-lesional S. neurona merozoites and schizonts. Diagnosis was confirmed immunohistochemically by staining with S. neurona-specific antibodies, and by phylogenetic analyses of conserved and variable portions of nuclear ribosomal DNA. On the basis of intense schizogony in the nasal mucosa, we propose the possibility of an olfactory nerve pathway route of infection for S. neurona meningoencephalitis.

    We present a case of previously healthy, immunocompetent, 41-year-old woman who developed systemic inflammatory response syndrome secondary to Neisseria gonorrhoeae bacteremia. Clinical course was complicated by the simultaneous formation of multiple muscular abscesses, epidural abscess, and septic spondylodiscitis. The patient responded well to prolonged ceftriaxone treatment and was released 10 weeks after initial admission. Spinal lesions and/or pyomyositis individually constitute rare complications of disseminated gonococcal infection. This case, combining both manifestations, is to our knowledge unique. Apropos, diversity of the clinical presentation, and therapeutic challenges for this historical disease are discussed for the practicing physician. PMID:28116187

    We report the neuroimaging and histopathologic findings of a 12-year-old female patient with a disseminated oligodendroglial-like leptomeningeal tumor with anaplastic progression and presumed extraneural metastatic disease. These tumors may represent distinct pathology primarily seen in pediatric patients. Neuroimaging demonstrates diffuse, progressive enhancement of the leptomeninges often with interval development of intraparenchymal lesions on follow-up. Disease is typically confined to the central nervous system, though diffuse peritoneal disease was seen in our case, possibly through metastatic seeding of the abdomen via ventriculoperitoneal shunt.

    We purposed to study energy expenditure, power output and gross efficiency during kayak ergometer exercise in 12 elite sprint kayakers. 6 males (age 24.2±4.8 years, height 180.4±4.8 cm, body mass 79.7±8.5 kg) and 6 females (age 24.3±4.5 years, height 164.5±3.9 cm, body mass 65.4±3.5 kg), performed an incremental intermittent protocol on kayak ergometer with VO2 and blood lactate concentration assessment, a non-linear increase between power output and energy expenditure being observed. Paddling power output, energy expenditure and gross efficiency corresponding to VO2max averaged 199.92±50.41 W, 75.27±6.30 ml.kg - 1.min - 1, and 10.10±1.08%. Male kayakers presented higher VO2max, power output and gross efficiency at the VO2max, and lower heart rate and maximal lactate concentration than females, but no differences were found between genders regarding energy expenditure at VO2max. Aerobic and anaerobic components of energy expenditure evidenced a significant contribution of anaerobic energy sources in sprint kayak performance. Results also suggested the dependence of the gross efficiency on the changes in the amount of the aerobic and anaerobic contributions, at heavy and severe intensities. The inter-individual variance of the relationship between energy expenditure and the corresponding paddling power output revealed a relevant tracking for females (FDγ=0.73±0.06), conversely to the male group (FDγ=0.27±0.08), supporting that some male kayakers are more skilled in some paddling intensities than others.

    Meniscal ramp lesions are more frequently associated with anterior cruciate ligament (ACL) injuries than previously recognized. Some authors suggest that this entity results from disruption of the meniscotibial ligaments of the posterior horn of the medial meniscus, whereas others support the idea that it is created by a tear of the peripheral attachment of the posterior horn of the medial meniscus. Magnetic resonance imaging (MRI) scans have been reported to have a low sensitivity, and consequently, ramp lesions often go undiagnosed. Therefore, to rule out a ramp lesion, an arthroscopic evaluation with probing of the posterior horn of the medial meniscus should be performed. Several treatment options have been reported, including nonsurgical management, inside-out meniscal repair, or all-inside meniscal repair. In cases of isolated ramp lesions, a standard meniscal repair rehabilitation protocol should be followed. However, when a concomitant ACL reconstruction (ACLR) is performed, the rehabilitation should follow the designated ACLR postoperative protocol. The purpose of this article was to review the current literature regarding meniscal ramp lesions and summarize the pertinent anatomy, biomechanics, diagnostic strategies, recommended treatment options, and postoperative protocol.

    The western Swiss Plateau with Lake Neuchâtel is part of the alpine foreland and among the key areas for the reconstruction of environmental changes since the last postglacial. This study was carried out in a landscape located NE of the lake and called Grosses Moos (The Large Fen) - currently designated the Swiss largest, continuous farming area, after the fen was drained in course of landscape engineering projects performed in Switzerland at the end of the 19th century. The study contributes new results from nine excavations of littoral ridges identified in Grosses Moos, and integrates sedimentology, paleo-environmental analysis and three independent chronological methods. Radiocarbon dating, pollen analysis and optically stimulated luminescence (OSL) were applied to the sediments. While pollen and radiocarbon follow the standard procedures, the evaluation of the luminescence age estimates demanded adjustment according to the physical and microdosimetric properties of the alpine quartz, and consideration of the peculiarities of the changing littoral environments of Grosses Moos. The Grosses Moos landscape developed on the temporary surface of the post-Last Glacial sedimentary infill of the over-deepened glacial Aare valley. In this study the landscape history has been fitted into the existing supraregional time scales of NGRIP, the Swiss bio-zones system and the human history based on archaeological and historic records and covers a time span of up to 15'000 yr b2k. The wide-ranging suite of geomorphic features and sedimentary sequences, including littoral lake sediments, beach ridges, dunes, palaeo-channels, peat and colluvial deposits, enable the extensive reconstruction of spatially and temporally variable natural shaping processes. In addition, our results indicate remobilization of soil, colluvium, and sediment due to human settlement activities since the Neolithic - with an important increase in sediment load and spatial variability since the Bronze Age

  8. Biomarkers of residual disease, disseminated tumor cells, and metastases in the MMTV-PyMT breast cancer model.

    Directory of Open Access Journals (Sweden)

    Christian Franci

    Full Text Available Cancer metastases arise in part from disseminated tumor cells originating from the primary tumor and from residual disease persisting after therapy. The identification of biomarkers on micro-metastases, disseminated tumors, and residual disease may yield novel tools for early detection and treatment of these disease states prior to their development into metastases and recurrent tumors. Here we describe the molecular profiling of disseminated tumor cells in lungs, lung metastases, and residual tumor cells in the MMTV-PyMT breast cancer model. MMTV-PyMT mice were bred with actin-GFP mice, and focal hyperplastic lesions from pubertal MMTV-PyMT;actin-GFP mice were orthotopically transplanted into FVB/n mice to track single tumor foci. Tumor-bearing mice were treated with TAC chemotherapy (docetaxel, doxorubicin, cyclophosphamide, and residual and relapsed tumor cells were sorted and profiled by mRNA microarray analysis. Data analysis revealed enrichment of the Jak/Stat pathway, Notch pathway, and epigenetic regulators in residual tumors. Stat1 was significantly up-regulated in a DNA-damage-resistant population of residual tumor cells, and a pre-existing Stat1 sub-population was identified in untreated tumors. Tumor cells from adenomas, carcinomas, lung disseminated tumor cells, and lung metastases were also sorted from MMTV-PyMT transplant mice and profiled by mRNA microarray. Whereas disseminated tumors cells appeared similar to carcinoma cells at the mRNA level, lung metastases were genotypically very different from disseminated cells and primary tumors. Lung metastases were enriched for a number of chromatin-modifying genes and stem cell-associated genes. Histone analysis of H3K4 and H3K9 suggested that lung metastases had been reprogrammed during malignant progression. These data identify novel biomarkers of residual tumor cells and disseminated tumor cells and implicate pathways that may mediate metastasis formation and tumor relapse after

    2016-05-01

    Disseminated histoplasmosis has a diverse and non-specific range of clinical signs and symptoms. In a significant minority of patients, cutaneous lesions are apparent at the time of initial presentation, affording an opportunity to establish the diagnosis from a skin biopsy. The most frequently reported clinical scenario in immunocompromised patients with cutaneous involvement is that of multiple papulo-nodular lesions on the face, trunk or extremities. The following report features an immunocompetent patient who presented with a solitary ulcerated plaque on the buttocks close to the anal verge. This case presentation underscores the broad spectrum of clinical presentations as well as the potential for diagnostic confusion with protozoa such as Leishmania or Trypanosoma species during histopathologic examination if special stains for fungal organisms are not performed.

    Full Text Available Case Report. A 47-year-old man presented with blurred vision in the right eye. Ophthalmoscopic examination showed several placoid, pigmented lesions in the posterior pole and midperiphery of the retina of both eyes. Results. Patient referred a cutaneous malignant melanoma on the back skin removed 6 years ago. A systemic workup revealed multiple metastases in liver and spleen. After an exhaustive study we concluded that it was a dissemination of a cutaneous malignant melanoma with bilateral choroidal metastases, liver and spleen metastases. The patient obtained clinical ocular improvement after palliative chemotherapy, although he died in the following months. Pathological examination of the lesions confirmed the diagnosis of choroidal metastases from a malignant cutaneous melanoma. Conclusions. Monitoring patients who have had cutaneous malignant melanoma is very important, since melanoma metastases may occur even many years after the diagnosis of the primary tumor. Choroidal metastases from cutaneous melanoma are uncommon but we should be aware because their appearance worsens prognosis.

    @@ This review describes disseminated intravascular coagulation(DIC) as a syndrome in which hemostatic factors are activated and products are generated. This syndrome ranges in severity from an obvious decompensated coagulopathy (overt-DIC) to the subclinical compensated activation of hemostatic factors(non-overt DIC). Ths first part of this review emphasizes two points: First, activation of the hemostatic system is controlled by a vast network of capillaries and venules through anticoagulant and antiinflammatory regulatory factors that operate from the endothelium( e. G. , protein C and thrombomodulin, tissue factor pathway inhibitor).

    Mice with unilateal striatal lesions created by 6-hydroxydopamine (6HDA) injection were screened for rotational (circling) behavior in response to injection of amphetamine and apomorphine. Those that rotated ipsilaterally in response to amphetamine and contralaterally in response to apomorphine were subsequently challenged with 1 to 3 g/kg (i.p.) ethanol. Surprisingly, ethanol induced dose related contralateral (apomorphine-like) rotation which, despite gross intoxication, was quite marked in most animals. No significant correlation was found between the number of turns made following ethanol and made after apomorphine or amphetamine. 14 references, 2 figures, 1 table.

  7. Diagnosis and treatment of disseminated intravascular coagulation.

    Science.gov (United States)

    Levi, M

    2014-06-01

    Disseminated intravascular coagulation (DIC) is a condition in which systemic activation of coagulation without a specific localization occurs, resulting in extensive formation of intravascular fibrin, particularly in small and midsize vessels. Disseminated intravascular coagulation may lead to several altered coagulation parameters, including a low platelet count, abnormal global clotting assays, low levels of physiological anticoagulant proteases, or increased fibrin degradation products. Also, more complex assays for activation of coagulation factors or pathways may indicate involvement of these molecules in DIC. None of these tests alone, however, can accurately ascertain or rebuff a diagnosis of DIC. Nonetheless, a combination of readily available routine assays may be instrumental in establishing a diagnosis of DIC and can also be useful to point to a subset of patients with DIC that may need definite, often costly, interventions in the hemostatic system. Current insights on relevant etiological pathways that may contribute to the occurrence of DIC have led to innovative therapeutic and adjunctive approaches to patient with DIC. Management options directed at the amelioration of hemostatic activation may tentatively be indicated and were found to be advantageous in experimental and clinical investigations. These treatments encompass elimination of tissue factor-mediated thrombin generation or restitution of normal anticoagulant function.

  8. New trends in knowledge dissemination: TED Talks

    Full Text Available This paper investigates the key elements of ethos, pathos and logos linguistic strategies as some main features of TED (Technology, Entertainment, Design Talks, popularizing speeches aiming at Knowledge Dissemination. Through a comparison between the TED Talk ‘HIV - How to fight an epidemic of bad laws’, by Shereen El-Feki (2012a, and another speech held by the same author at the  2012 Symposia The Global Commission on HIV and the Law, addressed to specialists, the paper analyses TED Talks as an innovative tool of popularization, which breaches the typical triangularisation ‘scientist-mediator-audience’, bringing scientists directly into contact with their audiences. Drawing upon Aristotle’s three pillars of rhetoric, the paper analyses the strategies used to establish the ethos of the speech, by proposing a topic as morally worth of spreading; pathos, by creating a direct contact with the public; and logos, investigated through an analysis of the elements used to recontextualise scientific discourses into popularized speeches. The analysis suggests that TED Talks are a recodification, not a mere translation of texts; they are a means to disseminate knowledge reducing the asymmetry between audiences and scientists.

    Introduction. According to the 2016 World Health Organization classification of Tumors of the Central Nervous System, the term Primitive Neuroectodermal Tumor has been replaced by the term Embryonal Tumor (ET). We present a case of disseminated cerebrospinal ET presenting in an adult patient. Illustrative Case. A 49-year-old male presenting with low back pain, dysuria, and hypoesthesia of the lower extremities referred to our emergency department. Brain and whole spine contrast-enhanced MRI documented a diffusively disseminated heterogeneous neoplasm with intradural extra- and intramedullary involvement of the cervicothoracic tract and cauda equina. A primary biopsy of the lumbosacral localization was performed through L5 bilateral laminectomy. Histologic diagnosis was Embryonal Tumor Not Otherwise Specified. The patient underwent chemotherapy with postoperative adjuvant alternating Vincristine-Doxorubicin-Ifosfamide (VAI) and Ifosfamide-Etoposide (IE). Discussion. Spinal ETs are exceedingly rare especially when presenting in the adult patient. Neurosurgical and oncologic management is still unclear. When feasible, surgical removal should always be performed to obtain a histologic diagnosis. Postoperative adjuvant therapy might entail both chemo- and radiotherapy; however a consensus on this matter is still lacking. PMID:27818821

    This project has provided a means to valorise the technical achievements of the CCT power generation RD&D activities arising from the ECSC and RFCS coal utilisation programmes. The focus has been on promotion and dissemination of such results to major coal-using Member States that have recently joined the European Union, namely Poland, the Czech Republic and Romania. A comprehensive review of the scope and achievements of the ECSC and RFCS projects on coal-fired power generation RD&D has been prepared and posted on the IEACCC website. This document has been translated by the partners in the three designated States and disseminated to their respective national stakeholders. Workshops have been held successfully in each country to promote the findings of the review and to determine their respective primary interests in future RD&D. The attendees have included representatives of major power plant operators, equipment manufacturers and developers, research institutes and universities. Very positive feedback was received from those stakeholders. The project has been completed with the circulation of the report and associated information to comparable stakeholders in the EU-15 countries and other newer members of the European Union via various networks and associations. 2 tabs., 3 apps.

    We report a case in which an HIV-infected man was cured of disseminated histoplasmosis (Histoplasma capsulatum var duboisii) after treatment by high-dose fluconazole (1,600 mg taken four times daily) for 2 months, combined with active antiretroviral therapy. The choice of fluconazole at this dosage was motivated by its availability as a generic and thus inexpensive medication, the patient's precarious status, and his critical clinical condition. At the end of the second month of treatment, the patient chose to stop the fluconazole, which he could no longer afford, while continuing the antiretroviral treatment, which was free. The clinical and laboratory improvement observed from the first week has continued to progress for more than 8 months after fluconazole treatment stopped. This single case needs - and deserves - to be confirmed in a series of patients. Nonetheless it makes it possible to envision fluconazole as a low-cost and efficacious antifungal agent for the treatment of disseminated histoplasmosis in AIDS patients in sub-Saharan Africa.

    SENTECH is a small energy and environmental consulting firm providing technical, analytical, and communications solutions to technology management issues. The activities proposed by SENTECH focused on gathering and developing communications materials and information, and various dissemination activities to present the benefits of hydrogen energy to a broad audience while at the same time establishing permanent communications channels to enable continued two-way dialog with these audiences in future years. Effective communications and information dissemination is critical to the acceptance of new technology. Hydrogen technologies face the additional challenge of safety preconceptions formed primarily as a result of the crash of the Hindenburg. Effective communications play a key role in all aspects of human interaction, and will help to overcome the perceptual barriers, whether of safety, economics, or benefits. As originally proposed SENTECH identified three distinct information dissemination activities to address three distinct but important audiences; these formed the basis for the task structure used in phases 1 and 2. The tasks were: (1) Print information--Brochures that target the certain segment of the population and will be distributed via relevant technical conferences and traditional distribution channels. (2) Face-to-face meetings--With industries identified to have a stake in hydrogen energy. The three industry audiences are architect/engineering firms, renewable energy firms, and energy companies that have not made a commitment to hydrogen (3) Educational Forums--The final audience is students--the future engineers, technicians, and energy consumers. SENTECH will expand on its previous educational work in this area. The communications activities proposed by SENTECH and completed as a result of this cooperative agreement was designed to compliment the research and development work funded by the DOE by presenting the technical achievements and validations

    1987-11-01

    A series of 12 patients with mass lesions arising from Meckel's cave is presented. Patients' age on presentation ranged from 13 months to 71 years. Nine of the 12 patients had symptoms referable to the fifth cranial nerve, but only three complained of facial pain. The 12 patients presented eight different pathological entities, including meningioma, lipoma, schwannoma, malignant melanotic schwannoma, arachnoid cyst, neurofibroma, epidermoid tumor, and chordoma. Computerized tomography and magnetic resonance imaging were most useful in localizing the lesion to Meckel's cave. All 12 patients underwent a subtemporal approach to the lesion, and gross total removal was achieved in 11. Postoperative results were excellent with no increased neurological deficits seen 3 months postoperatively. Most patients had resolution of the cranial nerve deficits except for fifth nerve function, which was impaired in nine patients postoperatively. This series demonstrates that lesions in Meckel's cave can have a varied and unusual presentation, as well as an assortment of pathology. Total removal of lesions in this area resulted in relief of symptoms in most patients, with minimum morbidity.

  18. The response of gross nitrogen mineralization to labile carbon inputs

    Science.gov (United States)

    Bengtson, Per

    2014-05-01

    Input of labile carbon sources to forest soils commonly result in priming, i.e. an increase in the microbial decomposition of soil organic matter. Efforts aimed at quantifying the extent of priming have, to date, largely focused on soil organic matter decomposition manifested as soil respiration. Less is known about how gross nitrogen mineralization responds to input of labile carbon. It is often assumed that increased priming results in decreased soil carbon stocks. However, microbial mineralization of organic nitrogen into plant available forms is a major factor limiting primary production in forests. If increased decomposition of soil organic matter in response to labile carbon is accompanied by a concurrent increased nitrogen mineralization, this could result in elevated primary production and higher rates of plant derived organic matter input to soils. Therefore, in order to fully understand the effect of priming on net ecosystem exchange and soil carbon stocks, it is vital to consider if increased decomposition of soil organic matter caused by priming also results in increased nitrogen mineralization. Here I present the results from a series of experiments aimed at determining if, and to which extent, gross nitrogen mineralization is stimulated by input of labile carbon. The results suggest that it is by no means uncommon to find an increase in gross N mineralization rates in response to labile carbon inputs. The magnitude of the increase seems dependent on the nitrogen status of the soil, as well as the concentration and rate of labile carbon inputs. However, continuous input of labile carbon sources that also contains nitrogen, e.g. amino acids, seems to inhibit rather than increase the mineralization of organic nitrogen. These findings suggest that there is a potential for a positive feedback between priming and primary production that needs to be considered in order to fully understand the influence of priming on net ecosystem exchange and soil carbon

  19. The Schroedinger functional for Gross-Neveu models

    Energy Technology Data Exchange (ETDEWEB)

    Leder, B.

    2007-04-18

    Gross-Neveu type models with a finite number of fermion flavours are studied on a two-dimensional Euclidean space-time lattice. The models are asymptotically free and are invariant under a chiral symmetry. These similarities to QCD make them perfect benchmark systems for fermion actions used in large scale lattice QCD computations. The Schroedinger functional for the Gross-Neveu models is defined for both, Wilson and Ginsparg-Wilson fermions, and shown to be renormalisable in 1-loop lattice perturbation theory. In two dimensions four fermion interactions of the Gross-Neveu models have dimensionless coupling constants. The symmetry properties of the four fermion interaction terms and the relations among them are discussed. For Wilson fermions chiral symmetry is explicitly broken and additional terms must be included in the action. Chiral symmetry is restored up to cut-off effects by tuning the bare mass and one of the couplings. The critical mass and the symmetry restoring coupling are computed to second order in lattice perturbation theory. This result is used in the 1-loop computation of the renormalised couplings and the associated beta-functions. The renormalised couplings are defined in terms of suitable boundary-to-boundary correlation functions. In the computation the known first order coefficients of the beta-functions are reproduced. One of the couplings is found to have a vanishing betafunction. The calculation is repeated for the recently proposed Schroedinger functional with exact chiral symmetry, i.e. Ginsparg-Wilson fermions. The renormalisation pattern is found to be the same as in the Wilson case. Using the regularisation dependent finite part of the renormalised couplings, the ratio of the Lambda-parameters is computed. (orig.)

  20. Verbal priming and taste sensitivity make moral transgressions gross.

    Science.gov (United States)

    Herz, Rachel S

    2014-02-01

    The aims of the present study were to assess whether: (a) visceral and moral disgust share a common oral origin (taste); (b) moral transgressions that are also viscerally involving are evaluated accordingly as a function of individual differences in taste sensitivity; (c) verbal priming interacts with taste sensitivity to alter how disgust is experienced in moral transgressions; and (d) whether gender moderates these effects. Standard tests of disgust sensitivity, a questionnaire developed for this research assessing different types of moral transgressions (nonvisceral, implied-visceral, visceral) with the terms "angry" and "grossed-out," and a taste sensitivity test of 6-n-propylthiouracil (PROP) were administered to 102 participants. Results confirmed past findings that the more sensitive to PROP a participant was the more disgusted they were by visceral, but not moral, disgust elicitors. Importantly, the findings newly revealed that taste sensitivity had no bearing on evaluations of moral transgressions, regardless of their visceral nature, when "angry" was the emotion primed. However, when "grossed-out" was primed for evaluating moral violations, the more intense PROP tasted to a participant the more "grossed-out" they were by all transgressions. Women were generally more disgust sensitive and morally condemning than men, but disgust test, transgression type, and priming scale modulated these effects. The present findings support the proposition that moral and visceral disgust do not share a common oral origin, but show that linguistic priming can transform a moral transgression into a viscerally repulsive event and that susceptibility to this priming varies as a function of an individual's sensitivity to the origins of visceral disgust-bitter taste.

    Objective To review current knowledge of the Morel-Lavallee lesion (MLL) to help clinicians become familiar with this entity.Familiarization may decrease missed diagnoses and misdiagnoses.It could also help steer the clinician to the proper treatment choice.Data sources A search was performed via PubMed and EMBASE from 1966 to July 2013 using the following keywords:Morel-Lavallee lesion,closed degloving injury,concealed degloving injury,Morel-Lavallee effusion,Morel-Lavallee hematoma,posttraumatic pseudocyst,posttraumatic soft tissue cyst.Study selection Chinese and English language literatures relevant to the subject were collected.Their references were also reviewed.Results Morel-Lavallee lesion is a relatively rare condition involving a closed degloving injury.It is characterized by a filled cystic cavity created by separation of the subcutaneous tissue from the underlying fascia.Apart from the classic location over the region of the greater trochanter,MLLs have been described in other parts of the body.The natural history of MLL has not yet been established.The lesion may decrease in volume,remain stable,enlarge progressively or show a recurrent pattern.Diagnosis of MLL was often missed or delayed.Ultrasonography,computed tomography,and magnetic resonance imaging have great value in the diagnosis of MLL.Treatment of MLL has included compression,local aspiration,open debridement,and sclerodesis.No standard treatment has been established.Conclusions A diagnosis of MLL should be suspected when a soft,fluctuant area of skin or chronic recurrent fluid collection is found in a region exposed to a previous shear injury.Clinicians and radiologists should be aware of both the acute and chronic appearances to make the correct diagnosis.Treatment decisions should base on association with fractures,the condition of the lesion,symptom and desire of the patient.

    We give an exhaustive characterization of the complex saddle point configurations of the Gross-Witten-Wadia matrix model in the large-N limit. In particular, we characterize the cases in which the saddles accumulate in one, two, or three arcs, in terms of the values of the coupling constant and of the fraction of the total unit density that is supported in one of the arcs, and derive an explicit condition for gap closing associated to nonvacuum saddles. By applying the idea of large-N instanton we also give direct analytic derivations of the weak-coupling and strong-coupling instanton actions.

    The underutilized practice of photographing anatomic pathology specimens from surgical pathology and autopsies is an invaluable benefit to patients, clinicians, pathologists, and students. Photographic documentation of clinical specimens is essential for the effective practice of pathology. When considering what specimens to photograph, all grossly evident pathology, absent yet expected pathologic features, and gross-only specimens should be thoroughly documented. Specimen preparation prior to photography includes proper lighting and background, wiping surfaces of blood, removing material such as tubes or bandages, orienting the specimen in a logical fashion, framing the specimen to fill the screen, positioning of probes, and using the right-sized scale.

  4. Four loop renormalization of the Gross-Neveu model

    Gracey, J A; Schroder, Y

    2016-01-01

    We renormalize the SU(N) Gross-Neveu model in the modified minimal subtraction (MSbar) scheme at four loops and determine the beta-function at this order. The theory ceases to be multiplicatively renormalizable when dimensionally regularized due to the generation of evanescent 4-fermi operators. The first of these appears at three loops and we correctly take their effect into account in deriving the renormalization group functions. We use the results to provide estimates of critical exponents relevant to phase transitions in graphene.

    Experimental nuclear moments of inertia at high spins along the yrast line have been determined systematically and found to differ from the rigid-body values. The difference is attributed to shell effects and these have been calculated microscopically. The data and quantal calculations are interpreted by means of the semiclassical Periodic Orbit Theory. From this new perspective, features in the moments of inertia as a function of neutron number and spin, as well as their relation to the shell energies can be understood. Gross shell effects persist up to the highest angular momenta observed.

    We consider the sectoral composition of a country's gross domestic product (GDP), i.e., the partitioning into agrarian, industrial, and service sectors. Exploring a simple system of differential equations, we characterize the transfer of GDP shares between the sectors in the course of economic development. The model fits for the majority of countries providing four country-specific parameters. Relating the agrarian with the industrial sector, a data collapse over all countries and all years supports the applicability of our approach. Depending on the parameter ranges, country development exhibits different transfer properties. Most countries follow three of eight characteristic paths. The types are not random but show distinct geographic and development patterns.

    Full Text Available Rational discovery of novel immunodiagnostic and vaccine candidate antigens to control bovine tuberculosis (bTB requires knowledge of disease immunopathogenesis. However, there remains a paucity of information on the Mycobacterium bovis-host immune interactions during the natural infection. Analysis of 247 naturally PPD+ M. bovis-infected cattle revealed that 92% (n = 228 of these animals were found to display no clinical signs, but presented severe as well as disseminated bTB-lesions at post-mortem examination. Moreover, dissemination of bTB-lesions positively correlated with both pathology severity score (Spearman r = 0.48; p<0.0001 and viable tissue bacterial loads (Spearman r = 0.58; p = 0.0001. Additionally, granuloma encapsulation negatively correlated with M. bovis growth as well as pathology severity, suggesting that encapsulation is an effective mechanism to control bacterial proliferation during natural infection. Moreover, multinucleated giant cell numbers were found to negatively correlate with bacterial counts (Spearman r = 0.25; p = 0.03 in lung granulomas. In contrast, neutrophil numbers in the granuloma were associated with increased M. bovis proliferation (Spearman r = 0.27; p = 0.021. Together, our findings suggest that encapsulation and multinucleated giant cells control M. bovis viability, whereas neutrophils may serve as a cellular biomarker of bacterial proliferation during natural infection. These data integrate host granuloma responses with mycobacterial dissemination and could provide useful immunopathological-based biomarkers of disease severity in natural infection with M. bovis, an important cattle pathogen.

    Full Text Available Introduction: Histoplasmosis is a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum. We report a case of disseminated cutaneous histoplasmosis with mucocutaneous involvement in an AIDS patient paradigmatic of the multifaceted nature of the disease, which is an expression of the immune reconstitution inflammatory syndrome (IRIS.Patient presentation: A 39-year-old man presented with a three month history of asymptomatic papules and nodules with necrotic centres involving the centrofacial region. The patient was diagnosed as being HIV-positive a month earlier and was commenced on antiretroviral treatment. Two weeks after the development of skin lesions, the patient complained of a sore throat and hoarseness of his voice. A fibre-optic laryngoscopy and biopsies of the skin, larynx and liver were performed.Management and outcome: The CD4 counts increased from 2 cells/µL to 124 cells/µL, whereas the viral load decreased from one million to less than 20 copies/mL. A fibre-optic laryngoscopy revealed a supraglottitis with ulceration on the epiglottis. Histology of the liver, larynx and sections of the skin demonstrated pandermal necrotising granulomatous inflammation. Grocott-Gomori methenamine silver and Periodic acid–Schiff (PAS stains revealed a relative paucity of intracellular, narrow-neck budding fungal organisms. Culture findings confirmed the diagnosis of histoplasmosis. The patient was treated with intravenous amphotericin B for two weeks followed by oral itraconazole 100 mg twice a day, with an excellent response to treatment.Conclusion: We present this case to remind clinicians that disseminated histoplasmosis in AIDS patients may occur as an expression of IRIS. A sudden onset of hoarseness with cutaneous lesions in a patient with disseminated disease should alert one to possible laryngeal histoplasmosis. Prompt recognition and treatment will avert the potential fatal complications of this disease.

    Full Text Available AbstractObjective: To investigate the impact of respiratory motion on localization, and quantification lung lesions for the Gross Tumour Volume utilizing an in-house developed Auto3Dreg programme and dynamic NURBS-based cardiac-torso digitised phantom (NCAT. Methods: Respiratory motion may result in more than 30% underestimation of the SUV values of lung, liver and kidney tumour lesions. The motion correction technique adopted in this study was an image-based motion correction approach using, an in-house developed voxel-intensity-based and a multi-resolution multi-optimisation (MRMO algorithm. All the generated frames were co-registered to a reference frame using a time efficient scheme. The NCAT phantom was used to generate CT attenuation maps and activity distribution volumes for the lung regions. Quantitative assessment including Region of Interest (ROI, image fidelity and image correlation techniques, as well as semi-quantitative line profile analysis and qualitatively overlaying non-motion and motion corrected image frames were performed. Results: the largest transformation was observed in the Z-direction. The greatest translation was for the frame 3, end inspiration, and the smallest for the frame 5 which was closet frame to the reference frame at 67% expiration. Visual assessment of the lesion sizes, 20-60mm at 3 different locations, apex, mid and base of lung showed noticeable improvement for all the foci and their locations. The maximum improvements for the image fidelity were from 0.395 to 0.930 within the lesion volume of interest. The greatest improvement in activity concentration underestimation, post motion correction, was 7% below the true activity for the 20 mm lesion. The discrepancies in activity underestimation were reduced with increasing the lesion sizes. Overlay activity distribution on the attenuation map showed improved localization of the PET metabolic information to the anatomical CT images. Conclusion: The respiratory

    The pathology lesions from three studies, two with butylated hydroxyanisole (BHA) and one with butylated hydroxytoluene (BHT), are reviewed. When BHA was fed at 0.5 and 2.0% of the diet to F344 rats for two years, there was an increase in epithelial hyperplasia of the forestomach at both treatment levels. Papilloma and squamous-cell carcinoma of the forestomach were increased at the 2.0% level. When BHA was fed to beagle dogs at 1.0 and 1.3% of the diet for 180 days, no lesions/tumours of the distal oesophagus or stomach could be identified either at gross necropsy or by light or electron microscopy. The BHT was fed to Wistar rats at 0, 25, 100 and 250 mg/kg body weight. At the highest dose there was an increase in the number of rats with hepatocellular adenoma and with hepatocellular carcinoma.

Document analysis and interviews were used and results were compared with similar strategies employed by staff at the National Health Service Institute for Innovation (NHSI) and improvement in Great Britain and the Odense University Hospital in Denmark. The Lean improvement programme was introduced to tackle challenges such as an ageing society, rising care expectations and budgetary and economic constraints. It was designed as a long-term programme to create added value for patients and employee involvement. The dissemination strategy was: forming clear visions and objectives; piloting; training potential adopters; and formal dissemination. The CCO strategy was focused primarily on managers and was not meant to involve all staff until the implementation stage. Staff at the NHSI attempted to address nurses needs during dissemination, which questioned whether the CCO managers' dissemination strategy is sustainable. This paper inspires healthcare managers and decision makers who aim to disseminate Lean production in their organisations. There are many case studies describing Lean implementation in single healthcare organisations, but little is known about effective dissemination and implementation strategies in large healthcare systems. The authors, therefore, suggest activities for developing and implementing dissemination strategies in multiple healthcare organisations.

    Incidental renal lesions are relatively common in daily radiological practice. It is important to know the different diagnostic possibilities for incidentally detected lesions, depending on whether they are cystic or solid. The management of cystic lesions is guided by the Bosniak classification. In solid lesions, the goal is to differentiate between renal cancer and benign tumors such as fat-poor angiomyolipoma and oncocytoma. Radiologists need to know the recommendations for the management of these lesions and the usefulness of the different imaging techniques and interventional procedures in function of the characteristics of the incidental lesion and the patient's life expectancy.

    The interaction of humans with radioactivity present in the environment from natural and artificial sources necessitates an evaluation of its risk on human health. Gross alpha and gross beta activities can provide a rapid evaluation of the radioactive content of a sample and can be simultaneously determined by using liquid scintillation counters. However, calibration of the liquid scintillation counter is required and is affected by many factors, such as particle energy and the acidity of the media. This study investigates what effect the particle energy used for calibration has on misclassification and how to account for this misclassification in routine measurements. The variability in measurement produced by the final pH, as well as any acids used in sample treatment, was also studied. These results showed that the most commonly used acid for these types of analyses, HNO{sub 3}, produced a high amount of misclassifications at very low pH. The results improved when HCl was used to adjust the sample to low pH. - Highlights: Black-Right-Pointing-Pointer We study the effect of alpha and beta energies on PSA optimisation. Black-Right-Pointing-Pointer The optimum PSA shifts to higher values as the alpha energy increases. Beta energies do not affect it. Black-Right-Pointing-Pointer We study the effect of pH on the simultaneous determination of gross alpha/beta activities. Black-Right-Pointing-Pointer HNO{sub 3} produces a high amount of misclassification at very low pH. Black-Right-Pointing-Pointer The results improve when HCl is used to adjust the sample to low pH.

  18. Telemedicine: challenges to dissemination in Brazil

    Jose Manuel Santos de Varge Maldonado

    Full Text Available Abstract: Telemedicine has been seen as an important tool for facing the challenges of universal health systems. The goal of this article is to discuss the main challenges to its full dissemination in Brazil. Being a somewhat new area, there are not many scientific papers that systematize it. This article is an exploratory paper, as it aims to provide an overall perspective on the subject. From an economic point of view, telemedicine is a strategic area due to its an intrinsic potential of being a source for generating innovation, for requiring and incorporating technological breakthroughs from other areas, and for its interdisciplinary nature and dynamic inter-relations that drive different industries. From the social perspective, it has the potential to make access to health services democratic, by connecting remote regions with health services located in hospitals and centers of reference for prevention, diagnosis and treatment.

    Disseminated intravascular coagulation (DIC) is a syndrome characterized by the systemic activation of blood coagulation. Its pathophysiological mechanisms are complex and dependent on the underlying pathology, making the clinical and biological expression of quite variable DIC. Among the various biological parameters disrupted, most are not specific, and none of them allows in itself to make the diagnosis. All this does not facilitate the task of the practitioner for diagnosis of overt DIC, much less that of the non-overt DIC, early stage whose treatment would improve the prognosis. These considerations have led to develop scores, combining several parameters depending on their availability in daily practice, as well as their diagnostic relevance. Of all the scores, the ISTH (International society of thrombosis and hemostasis) remains the most used.

    Lymphocyte proliferation, mobility and longevity make them prime targets for virus infection. Myeloid cells that process and present environmental antigens to lymphocytes are consequently an important line of defence. Subcapsular sinus macrophages (SSMs) filter the afferent lymph and communicate with B-cells. How they interact with B-cell-tropic viruses is unknown. We analysed their encounter with murid herpesvirus-4 (MuHV-4), an experimentally accessible gammaherpesvirus related to Kaposi's sarcoma-associated herpesvirus. MuHV-4 disseminated via lymph nodes, and intranasally or subcutaneously inoculated virions readily infected SSMs. However, this infection was poorly productive. SSM depletion with clodronate-loaded liposomes or with diphtheria toxin in CD169-diphtheria toxin receptor transgenic mice increased B-cell infection and hastened virus spread to the spleen. Dendritic cells provided the main route to B-cells, and SSMs slowed host colonization, apparently by absorbing virions non-productively from the afferent lymph.

    Through Natural Language Processing (NLP) techniques, information can be extracted from clinical narratives for a variety of applications (e.g., patient management). While the complex and nested output of NLP systems can be expressed in standard formats, such as the eXtensible Markup Language (XML), these representations may not be directly suitable for certain end-users or applications. The availability of a âeuro tabular' format that simplifies the content and structure of NLP output may facilitate the dissemination and use by users who are more familiar with common spreadsheet, database, or statistical tools. In this paper, we describe the knowledge-based design of a tabular representation for NLP output and development of a transformation program for the structured output of MedLEE, an NLP system at our institution. Through an evaluation, we found that the simplified tabular format is comparable to existing more complex NLP formats in effectiveness for identifying clinical conditions in narrative reports.

    Full Text Available Every drug comes with some side effect. It is the benefit/risk ratio that determines the medical use of the drug. Quinine, a known antimalarial drug, has been used for nocturnal leg cramps since the 1930s; it is associated with severe life-threatening hematological and cardiovascular side effects. Disseminated intravascular coagulation (DIC, albeit rare, is a known coagulopathy associated with Quinine. It is imperative to inquire about the Quinine intake in medication history in patients with coagulopathy, as most patients still consider it a harmless home remedy for nocturnal leg cramps. In this report, we present a case of coagulopathy in a middle-aged woman, who gave a history of taking Quinine for nocturnal leg cramps, as her home remedy. Early identification of the offending agent led to the diagnosis, prompt discontinuation of the medication, and complete recovery and prevented the future possibility of recurrence.

    A fluorodeoxyglucose (FDG) positron emission tomography (PET)-computer tomography (CT) scan for staging. No definite abnormal FDG uptake of the stomach was shown. Incidentally, variable FDG uptake at the bilateral serrates muscles, abdominal muscles and muscles of both thighs (Fig. 1) was observed. He had no significant past medical history except recently diagnosed stomach cancer. On personal interview, he described having had sexual activity the night before the F-18 FDG PET/CT scan, although he was aware of needing to avoid physical activity before a PET scan. The F-18 FDG PET/CT scan was done at 2:00 p.m. Therefore, the hypermetabolism of individual skeletal muscles following sexual activity lasted over 12 h. This case illustrates the hypermetabolism of skeletal muscles following sexual activity as a normal variation.

    Poliomyelitis is an acute disease of the central nervous system (CNS) caused by poliovirus (PV). In humans, an infection is initiated by oral ingestion of the virus, followed by multiplication in the alimentary mucosa, from which the virus spreads through the bloodstream. Paralytic poliomyelitis initiates from the invasion of the central nervous system by circulating poliovirus, probably via the blood-brain barrier. After the virus enters the central nervous system, it replicates in neurons, especially in motor neurons, inducing the cell death that causes paralytic poliomyelitis. Along with this route of dissemination, a neuron-specific pathway has been reported in humans, monkeys, and PV-sensitive transgenic (Tg) mice carrying the PV receptor (hPVR/CD155) gene. It is important for the efficient virus dissemination to overcome the barriers as follows; i) to access the target tissue, ii) to enter the cells, iii) to reach the place for the replication, iv) to replicate efficiently. PV is easily transferred to humans orally; however, no rodent model for oral infections has been developed. We analyzed the each barrier above, and showed that PV is inactivated by the low pH of the gastric contents in mice. We also demonstrated that type 1 interferon signaling plays an important role in determining permissivity in the alimentary tract. As for the neural pathway, we demonstrated that direct efficient interaction between the cytoplasmic domain and cytoplasmic dynein is essential for the efficient retrograde transport of PV-containing vesicles along microtubules for the hPVR-dependent PV transport. On the other hand, we found that hPVR-independent axonal transport of PV was also observed in hPVR-Tg and non-Tg mice, indicating that several different pathways for PV axonal transport exist.

    39 years old man with granulomatous lesions in both lungs caused by occupational contact with glass fibers was described. He has been working as an bricklayer-plasterer for 18 years and was in contact with lime, cement, plaster, asbestos, dust of coal and wood and with glass fibers. For the last two years before admission in 1993 he has had frequent bronchial infections. On admission he was in good general condition, his spirometric examination and blood gases were within normal limits. On chest x-ray disseminated lesions were found. Those lesions were of the round shapes on chest CT. Many sputum cultures for tubercle bacilli were negative. ANA and ANCA were not found in the serum. ACE was within normal limits. No precipitins to environmental antigens were found. Cancer metastases were suspected and lung biopsy during videothoracoscopy was done. Many foreign body type granulomas were found throughout the specimen. The character of the lesions was not typical for tuberculosis, sarcoidosis, extrinsic allergic alveolitis, silicosis or asbestosis. There are some reports concerning the possibility of development of such lesions after the exposition to glass fibers. We suspect that case is an example of such pathology. His occupational exposition was stopped in 1993 and he was observed without treatment. During the 5 years of observation (up till 1998) he was in good health with stable chest x-ray picture and results of respiratory system function.

    Full Text Available This case report details an interesting case of suspected spinal bifida in an obstetric patient who presented for an elective cesarean section. A large scarred/dimpled area, surrounded by significant hair growth in the region of the lumbar spine had been missed in multiple antenatal and preoperative assessments and was recognized on the day of the surgery as the patient was being prepared for spinal anesthesia. The patient was uncertain regarding the pathology of the lesion, and all investigations relating to this had been undertaken in Pakistan where she lived as a child. General anesthesia was undertaken because magnetic resonance imaging had not been performed and tethering of the spinal cord could not be ruled out clinically. The patient suffered from significant blood loss intra and postoperatively, requiring a two unit blood transfusion. She was discharged after 5 days in the hospital. This case highlights the need for thorough examination in all obstetric patients presenting to the preoperative clinic, focusing on the airway, vascular access, and lumbar spine. Patients may not always disclose certain information due to a lack of understanding, embarrassment, forgetfulness, or language barriers. Significant aspects of their care may have been undertaken abroad and access to these notes is often limited. Preoperative detection of the lesion would have allowed further investigation and imaging of the lesion and enabled more comprehensive discussions with the patient regarding anesthetic options and risk.

    2017-03-01

    We present the results from an ultrasound-guided focused ultrasound platform designed to perform real-time monitoring and control of lesion formation. Real-time signal processing of echogenicity changes during lesion formation allows for identification of signature events indicative of tissue damage. The detection of these events triggers the cessation or the reduction of the exposure (intensity and/or time) to prevent overexposure. A dual mode ultrasound array (DMUA) is used for forming single- and multiple-focus patterns in a variety of tissues. The DMUA approach allows for inherent registration between the therapeutic and imaging coordinate systems providing instantaneous, spatially-accurate feedback on lesion formation dynamics. The beamformed RF data has been shown to have high sensitivity and specificity to tissue changes during lesion formation, including in vivo. In particular, the beamformed echo data from the DMUA is very sensitive to cavitation activity in response to HIFU in a variety of modes, e.g. boiling cavitation. This form of feedback is characterized by sudden increase in echogenicity that could occur within milliseconds of the application of HIFU (see http://youtu.be/No2wh-ceTLs for an example). The real-time beamforming and signal processing allowing the adaptive control of lesion formation is enabled by a high performance GPU platform (response time within 10 msec). We present results from a series of experiments in bovine cardiac tissue demonstrating the robustness and increased speed of volumetric lesion formation for a range of clinically-relevant exposures. Gross histology demonstrate clearly that adaptive lesion formation results in tissue damage consistent with the size of the focal spot and the raster scan in 3 dimensions. In contrast, uncontrolled volumetric lesions exhibit significant pre-focal buildup due to excessive exposure from multiple full-exposure HIFU shots. Stopping or reducing the HIFU exposure upon the detection of such an

    The International Panel on the Diagnosis of Multiple Sclerosis (MS) incorporated the Barkhof/Tintore (B/T) magnetic resonance criteria into their diagnostic scheme to provide evidence of dissemination in space of central nervous system lesions, a prerequisite for diagnosing MS in patients who present with clinically isolated syndromes (CIS). Although specific for MS, the B/T criteria were criticised for their low sensitivity and relative complexity in clinical use. We used lesion characteristics at onset from 349 CIS patients in logistic regression and recursive partitioning modelling in a search for simpler and more sensitive criteria, while maintaining current specificity. The resulting models, all based on the presence of periventricular and deep white matter lesions, performed roughly in agreement with the B/T criteria, but were unable to provide higher diagnostic accuracy based on information from a single scan. Apparently, findings from contrast-enhanced and follow-up magnetic resonance scans are needed to improve the diagnostic algorithm. (orig.)

    Acute disseminated encephalomyelitis (ADEM) is usually a monophasic illness characterized by multiple lesions involving gray and white matter. Quantitative MR techniques were used to characterize and stage these lesions. Eight patients (seven males and one female; mean age 19 years, range 5 to 36 years) were studied using conventional MRI (T2- and T1-weighted and FLAIR sequences), diffusion-weighted imaging (DWI) and proton magnetic resonance spectroscopy (MRS). Apparent diffusion coefficient (ADC) values and MRS ratios were calculated for the lesion and for normal-appearing white matter (NAWM). Three patients were imaged in the acute stage (within 7 days of the onset of neurological symptoms) and five in the subacute stage (after 7 days from the onset of symptoms). ADC values in NAWM were in the range 0.7-1.24 x 10{sup -3} mm/s{sup 2} (mean 0.937 {+-} 0.17 mm/s{sup 2}). ADC values of ADEM lesions in the acute stage were in the range 0.37-0.68 x 10{sup -3} mm/s{sup 2} (mean 0.56 {+-} 0.16 mm/s{sup 2}) and 1.01-1.31 x 10{sup -3} mm/s{sup 2} (mean 1.24 {+-} 0.13 mm/s{sup 2}) in the subacute stage. MRS ratios were obtained for all patients. NAA/Cho ratios were in the range 1.1-3.5 (mean 1.93 {+-} 0.86) in the NAWM. NAA/Cho ratios within ADEM lesions in the acute stage were in the range 0.63-1.48 (mean 1.18 {+-} 0.48) and 0.29-0.84 (mean 0.49 {+-} 0.22) in the subacute stage. The ADC values, NAA/Cho and Cho/Cr ratios were significantly different between lesions in the acute and subacute stages (P < 0.001, P < 0.027, P < 0.047, respectively). ADC values were significantly different between lesions in the acute (P < 0.009) and subacute stages (P < 0.005) with NAWM. In addition, NAA/Cho and Cho/Cr ratios were significantly different between lesions in the subacute stage and NAWM (P < 0.006, P < 0.007, respectively). ADEM lesions were characterized in the acute stage by restricted diffusion and in the subacute stage by free diffusion and a decrease in NAA/Cho ratios

    This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute

  19. Hypothesis: Disseminated Intravascular Inflammation as the Inflammatory Counterpart to Disseminated Intravascular Coagulation

    Bull, Brian S.; Bull, Maureen H.

    1994-08-01

    We have identified a leukocyte activation syndrome that is occasionally associated with the transfusion of intraoperatively recovered erythrocytes. This syndrome appears to result from intravascular damage caused by leukocytes activated during the erythrocyte salvage process. We hypothesize that this syndrome is part of a larger disease grouping: disseminated intravascular inflammation (DII). DII is the analog of the coagulation disorder disseminated intravascular coagulation. In disseminated intravascular coagulation, the organ damage results from uncontrolled activation of the clotting pathway; in DII the damage is caused by leukocytes that have become activated by direct contact with bacteria or in rare instances-such as erythrocyte salvage-in the absence of bacteria and bacterial products. Recent studies of the hazards associated with intraoperative blood salvage indicate that activation of leukocytes can be achieved by exposure to activated platelets alone. If such activated leukocytes are reinfused along with the washed erythrocytes, widespread organ damage may result. The lung is the organ most severely affected by activated leukocytes. Adult respiratory distress syndrome is one outcome. It is likely that DII is a presently unrecognized pathophysiological process that complicates a variety of primary disease states and increases their lethality.

    While social impairment is considered to be the core deficit in children with autism spectrum disorder (ASD), a large proportion of these children have poor gross motor ability, and gross motor deficits may influence socialization skills in children with ASD. The objectives of this study were to compare gross motor skills in children with ASD to typically developing children, to describe gross motor problems in children with ASD, and to investigate associations between gross motor and socialization skills in children with ASD. This was a cross-sectional study including 40 ASD children aged from 18 months to 6 years and 40 age-matched typically developing controls. Gross motor and socialization skills were scored using the Vineland Adaptive Behavior Scales, 2(nd) edition (Vineland-II). Below average gross motor function was found in eight of 40 (20%) ASD children. The mean gross motor v-scale score in the ASD group was 15.1 [standard deviation (SD) 3.12], significantly lower than in the control group [18.7, SD 2.09, p = 0.0001; 95% confidence intervals (CI) from -4.725 to -2.525]. The differences were most prominent in ball throwing and catching, using stairs, jumping, and bicycling. The ASD children with gross motor impairments had a mean socialization domain score of 66.6 (SD 6.50) compared to 85.7 (SD 10.90) in those without gross motor impairments (p = 0.0001, 95% CI from -25.327 to -12.736). Children with ASD had lower gross motor skills compared to typically developing children. Gross motor impairments were found in 20% of the ASD children, and these children also had lower socialization skills than those without gross motor impairments. Copyright © 2016.

    Posaconazole is widely used for prophylaxis against invasive fungal infections in patients undergoing myeloablative therapy. Disseminated fusariosis is a serious invasive mold infection in such patients. Preclinical and clinical studies indicate activity of posaconazole against Fusarium. We describe two cases of disseminated fusariosis that occurred despite posaconazole prophylaxis.

  10. Optimal Bilinear Control of Gross--Pitaevskii Equations

    KAUST Repository

    Hintermüller, Michael

    2013-01-01

    A mathematical framework for optimal bilinear control of nonlinear Schrödinger equations of Gross--Pitaevskii type arising in the description of Bose--Einstein condensates is presented. The obtained results generalize earlier efforts found in the literature in several aspects. In particular, the cost induced by the physical workload over the control process is taken into account rather than the often used L^2- or H^1-norms for the cost of the control action. Well-posedness of the problem and existence of an optimal control are proved. In addition, the first order optimality system is rigorously derived. Also a numerical solution method is proposed, which is based on a Newton-type iteration, and used to solve several coherent quantum control problems.

    Full Text Available The shoulder girdle plays an important role in the large pointing workspace that humans enjoy. The goal of this work was to characterize the human shoulder girdle motion in relation to the arm. The overall motion of the human shoulder girdle was characterized based on motion studies completed on test subjects during voluntary (natural/unforced motion. The collected data from the experiments were used to develop surface fit equations that represent the position and orientation of the glenohumeral joint for a given humeral pointing direction. These equations completely quantify gross human shoulder girdle motion relative to the humerus. The equations are presented along with goodness-of-fit results that indicate the equations well approximate the motion of the human glenohumeral joint. This is the first time the motion has been quantified for the entire workspace, and the equations provide a reference against which to compare future work.

    Full Text Available The objective of this study is to examine the determinants of labor absorption in the trade, hotel and restaurant sector and its impact on Gross Regional Domestic Product/GRDP at Bali Province. This study is important due to the fact that the GRDP in this sector is the highest compared to other sector but the labor absorption is lower than the agriculture sector. This study used panel data comprising 9 regencies/cities at Bali Province in the period 2003-2009 including fixed effect model and simultaneous equation model of Two-Stage Least Square. The results showed that GRDP, working age population, and the minimum wage have positive effect on employment, while the educated unemployment has no significant effect on the employment in the trade, hotel and restaurant sector. In addition, increases in employment and workers productivity have positive and significant effects the GRDP in the trade, hotel and restaurant sector at Bali Province.

    2011-08-01

    Oceanic gross DMS production (GP) exerts a fundamental control on the concentration and the sea-air flux of this climatically-active trace gas. However, it is a poorly constrained process, owing to the complexity of the microbial food web processes involved and their interplay with physical forcing, particularly with solar radiation. The “inhibitor method”, using dimethyldisulfide (DMDS) or other compounds to inhibit bacterial DMS consumption, has been frequently used to determine GP in dark incubations. In the work presented here, DMDS addition was optimized for its use in light incubations. By comparing simultaneous dark and light measurements of GP in meso- to ultraoligotrophic waters, we found a significant enhancement of GP in natural sunlight in 7 out of 10 experiments. Such stimulation, which was generally between 30 and 80% on a daily basis, occurred throughout contrasting microbial communities and oceanographic settings.

    The massive Gross-Neveu model is solved in the large N limit at finite temperature and chemical potential. The scalar potential is given in terms of Jacobi elliptic functions. It contains three parameters which are determined by transcendental equations. Self-consistency of the scalar potential is proved. The phase diagram for non-zero bare quark mass is found to contain a kink-antikink crystal phase as well as a massive fermion gas phase featuring a cross-over from light to heavy effective fermion mass. For zero bare quark mass we recover the three known phases kink-antikink crystal, massless fermion gas, and massive fermion gas. All phase transitions are shown to be of second order. Equations for the phase boundaries are given and solved numerically. Implications on condensed matter physics are indicated where our results generalize the bipolaron lattice in non-degenerate conducting polymers to finite temperature.

    Kumar, Rakesh; Dave, Mayank

    2015-06-01

    The design of data dissemination protocol has been a great challenge due to the highly dynamic and unreliable wireless channel in vehicular ad hoc networks (VANET). In literature, several interesting solutions are proposed to perform data dissemination for this environment. But these solutions either use architectures requiring centralised coordination or global network knowledge or large intermediate buffers. In this paper, we propose a decentralised technique that overcomes above requirements and provides reliable and scalable communication in both dense and sparse traffic for VANET. Random walks are used in the proposed technique to disseminate data from one vehicle to other vehicles in the network. We use raptor codes to provide low decoding complexity and more scalability for data dissemination. Simulation results demonstrate that the proposed technique has better fault tolerance with lower complexity than general random-walk-based dissemination process and more scalability as compared to the other protocols.

    Full Text Available 800x600 ABSTRACT Students are expected to change the world. Their perspectives represent the way they view the world and its phenomena. The broader knowledge they possess, the more tolerance they have in interpreting life. In the global era, students should understand the importance of having good knowledge in multiculturalism. They will involve in an inter-cultural encounter since sources of information are widely offered. The willingness to have such an open mind is required in order to develop a better place to live and work. One way to disseminate multiculturalism values is using text containing information about culture and social values. The text written in English or Bahasa Indonesia for the class designed in disseminating multiculturalism is Translation. Here, students are taught to interpret the messages conveyed and translate the information from the source language to the target language correctly. Teacher must have good and creative technique in delivering the material so that students really enjoy the class and deeply understand the topic. The teaching and learning process in Translation class, therefore, is an effective medium to achieve the expected purpose as stated above. Theory of translation will not be the one and only theory to do the translation job, but it also needs comprehensive knowledge on other social sciences. Hence, translation class will not only discuss lines of words in a paragraph, but also reciprocal discussion among the members of the class. At the end, students will have the ability to translate such information in a text correctly and to establish civic society with more open comprehension over society and its culture.

    Full Text Available Hilar cholangiocarcinoma, also known as Klatskin tumour, is the commonest type of cholangiocarcinoma. It poses unique problems in the diagnosis and management because of its anatomical location. Curative surgery in the form of major hepatic resection entails significant morbidity. About 5–15% of specimens resected for presumed Klatskin tumour prove not to be cholangiocarcinomas. There are a number of inflammatory, infective, vascular, and other pathologies, which have overlapping clinical and radiological features with a Klatskin tumour, leading to misinterpretation. This paper aims to summarise the features of such Klatskin-like lesions that have been reported in surgical literature.

    2016-06-01

    Cystic lesions are commonly seen in the mediastinum, and they may arise from virtually any organ. The vast majority of these lesions are benign and result in no symptoms. When large, cysts may produce symptoms related to compression of adjacent structures. The most common mediastinal cysts are pericardial and foregut duplication cysts. Both computed tomography and magnetic resonance are routinely used to evaluate these lesions. Although computed tomography offers superior spatial resolution, magnetic resonance is useful in differentiating cysts that contain proteinaceous material from solid lesions. Occasionally, cysts arise from solid lesions, such as thymoma or teratoma. Although cysts are alike in appearance, location helps narrowing the differential diagnoses.

    Candidiasis is defined as an infection or disease caused by a fungus of the genus Candida. Rate of disseminated candidiasis increases with the growth of the number of immunocompromised patients. In the the last few decades the incidence of disseminated candidiasis is in growth as well as the mortality rate. The aim of this survey is to show the importance of serological tests implementation in disseminated candidiasis diagnose. This is a prospective study involving 60 patients with malign diseases with and without clinical signs of disseminated candidiasis and 30 healthy people who represent the control group. Apart from hemoculture, detection of circulating mannan antigen and adequate antibodies of Candida species applying comercial ELISA test was determined in each patient. This survey deals with relevant factors causing disseminated candidiasis. This survey showed that the group of patients with clinical signs of disseminated candidiasis had more patients with positive hemoculture to Candida species, then the group of patients without clinical signs of disseminated candidiasis. The number of patients being examined and positive to antigens and antibodies was higher (p candidiasis (7/30; 23.3%), then in the group of patients without clinical signs of disseminated candidiasis (0/30; 0%): Average value of titra antigen was statistically higher (p candidiasis 6/30 (20%) of patients had Candida spp.positive hemocultures while in the group of patients without clinical signs of disseminated candidiasis 1/30 (3.3%) of patients had Candida spp. positive hemocultures, which was considerably higher (p candidiasis were statistically significant, while correlation of results of hemoculture and antibodies was insignificant. Because of low sensitivity of hemoculture and time needed for isolation of Candida spp., introducing serological tests in regular procedures would speed disseminated candidiasis diagnose.

For IOFD the domestic medication alasens (the active agent – 5-aminolevulinic acid was used orally at dose of 30 mg/kg body weight 3 h prior to the study procedure. As the result of fluorescence diagnosis 10 (6.9% patients had peritoneal tumor dissemination verified morphologically and undetected by standard laporoscopy. The sensitivity of peritoneal revision for standard laparoscopy in patients with gastric cancer stage III–IV was 60.8%, the specificity – 75.8%, the overall accuracy – 69.1%. The sensitivity for IOFD in patients with gastric cancer stage III–IV was 91.1%, the specificity – 93.9%, the overall accuracy – 92.7%. Thus, fluorescence study allowed improving the specificity, the sensitivity and the overall accuracy of diagnostic test. In the trial IOFD had the maximal diagnostic value in patients with visually undetectable microdissemination in «whight» light and with solitary visible peritoneal foci (the average number of additionally detected metastatic lesions in one patient – 1.22 and 1.4, respectively. Moreover, in the case of fluorescence diagnosis the number of detected microfoci of peritoneal dissemination was showed to increase with enlargement of area of tumor invasion to gastric serosa (at average of 2.29 additionally detected lesions in one patient with serosal invasion more than 2 cm2. The obtained results confirm the perspective of use of fluorescence diagnosis for detection of peritoneal dissemination, determination of true tumor extent, staging of the tumor and also for adjustment of following treatment tactics for this group of patients.

    Wavelet theory is efficient as an adequate tool for analyzing single epoch GPS deformation signal. Wavelet analysis technique on gross error detection and recovery is advanced. Criteria of wavelet function choosing and Mallat decomposition levels decision are discussed. An effective deformation signal extracting method is proposed, that is wavelet noise reduction technique considering gross error recovery, which combines wavelet multi-resolution gross error detection results. Time position recognizing of gross errors and their repairing performance are realized. In the experiment, compactly supported orthogonal wavelet with short support block is more efficient than the longer one when discerning gross errors, which can obtain more finely analyses. And the shape of discerned gross error of short support wavelet is simpler than that of the longer one. Meanwhile, the time scale is easier to identify.

Clinical findings in healthy and diseased fawns from 0 to 90 days of age included bite and scratch marks followed by moderate to severe ear and tail necrosis. Gross necropsy findings of necrotizing ulcerative dermatitis correlated with histopathologic findings that included focally severe multifocal vasculitis, vascular necrosis, and thrombosis. This article is a clinical description of these previously unreported lesions associated with tissue necrosis in young captive white-tailed deer.

  12. Laboratory testing in disseminated intravascular coagulation.

    Favaloro, Emmanuel J

    2010-06-01

    The diagnosis of disseminated intravascular coagulation (DIC) relies on clinical signs and symptoms, identification of the underlying disease, the results of laboratory testing, and differentiation from other pathologies. The clinical features mainly depend on the underlying cause of the DIC. The laboratory diagnosis of DIC uses a combination of tests because no single test result alone can firmly establish or rule out the diagnosis. Global tests of hemostasis may initially provide evidence of coagulation activation and later in the process provide evidence of consumption of coagulation factors, but their individual diagnostic efficiency is limited. Fibrinolytic markers, in particular D-dimer, are reflective of activation of both coagulation and fibrinolysis, so that a normal finding can be useful for ruling-out DIC. Decreased levels of the natural anticoagulants (in particular, antithrombin and protein C) are frequently observed in patients with DIC, but their measurement is not normally incorporated into standard diagnostic algorithms. New tests are being explored for utility in DIC, and some additional tests may be useful on a case-by-case basis, depending on the proposed cause of the DIC or their local availability. For example, clot waveform analysis is useful but currently limited to a single instrument. Also, procalcitonin is an inflammatory biomarker that may be useful within the context of septic DIC, and activated factor X clotting time is an emerging test of procoagulant phospholipids that also seems to hold promise in DIC.

  13. Dissemination and experience with cognitive processing therapy

    Kathleen M. Chard, PhD

    Full Text Available Clinical practice guidelines suggest that cognitive behavioral therapies are recommended for the treatment of posttraumatic stress disorder (PTSD. One of these treatments, cognitive processing therapy (CPT, is an evidence-based treatment that has been shown to be effective at treating combat, assault, and interpersonal violence trauma in randomized controlled trials. The Department of Veterans Affairs (VA Office of Mental Health Services has implemented an initiative to disseminate CPT as part of a broad effort to make evidence-based psychotherapies widely available throughout the VA healthcare system. This article provides an overview of CPT and reviews the efficacy and program evaluation data supporting its use in a variety of settings. In addition, we report on survey data from individuals who have participated in the VA initiative and on outcome data from patients treated by rollout-trained therapists. Our data suggest that many clinicians trained in the rollout show good adoption of the CPT model and demonstrate solid improvements in their patients’ PTSD and depressive symptomotology.

    Using a modified epidemiological model, the dissemination of news by media agents after the occurrence of large scale disasters was studied. A modified compartmented model was developed in a previous paper presented at INAC 2007. There it used to study to the Chernobyl's nuclear accident (1986) and the Concorde airplane crash (2000). Now the model has been applied to a larger and more diverse group of events - nuclear, non-nuclear and naturally caused disasters. To be comprehensive, old and recent events from various regions of the world were selected. A more robust news repository was used, and improved search techniques were developed to ensure that the scripts would not count false positive news. The same model was used but with improved non-linear embedded simulation optimization algorithms to generate the parameters of interest for our model. Individual parameters and some specific combination of them allow some interesting perceptions on how the nature of the accident / disaster gives rise to different profiles of growth and decay of the news. In our studies events involving nuclear causes generate news repercussion with more explosive / robust surge profiles and longer decaying tails than those of other natures. As a consequence of these differences, public opinion and policy makers are also much more sensitive to some issues than to others. The model, through its epidemiological parameters, shows in quantitative manner how 'nervous' the media content generators are with respect to nuclear installations and how resilient this negative feelings about nuclear is.

    We propose a method for brain atlas deformation in the presence of large space-occupying tumors, based on an a priori model of lesion growth that assumes radial expansion of the lesion from its starting point. Our approach involves three steps. First, an affine registration brings the atlas and the patient into global correspondence. Then, the seeding of a synthetic tumor into the brain atlas provides a template for the lesion. The last step is the deformation of the seeded atlas, combining a method derived from optical flow principles and a model of lesion growth. Results show that a good registration is performed and that the method can be applied to automatic segmentation of structures and substructures in brains with gross deformation, with important medical applications in neurosurgery, radiosurgery, and radiotherapy.

    Fractures of the anteroinferior glenoid rim, termed bony Bankart lesions, have been reported to occur in up to 22% of first time anterior shoulder dislocations. The primary goal of treatment is to create a stable glenohumeral joint and a good shoulder function. Options for therapeutic intervention are largely dependent on the chronicity of the lesion, the activity level of the patient and postreduction fracture characteristics, such as the size, location and number of fracture fragments. Non-operative treatment can be successful for small, acute fractures, which are anatomically reduced after shoulder reduction. However, in patients with a high risk profile for recurrent instability initial Bankart repair is recommended. Additionally, bony fixation is recommended for acute fractures that involve more than 15-20% of the inferior glenoid diameter. On the other hand chronic fractures are generally managed on a case-by-case basis depending on the amount of fragment resorption and bony erosion of the anterior glenoid with high recurrence rates under conservative therapy. When significant bone loss of the anterior glenoid is present, anatomical (e.g. iliac crest bone graft and osteoarticular allograft) or non-anatomical (e.g. Latarjet and Bristow) reconstruction of the anterior glenoid is often indicated.

    Pilocytic astrocytoma (PA) is a low-grade tumor. It has an excellent prognosis after total resection. Leptomeningeal dissemination and hemorrhage are very rare to be associated with PA and lead to unfavorable prognosis. A 35-year-old man was diagnosed with a hemorrhagic suprasellar PA in 2006. Subsequent examination in 2007 revealed another large subdural hemorrhagic lesion in the sacral region, which proved to be PA by histopathologic assessment. Other leptomeningeal foci were discovered mainly at the craniocervical junction. The patient underwent subtotal resection and received chemotherapy with disease control for 7 years. Progression of the disseminated disease has recently occurred; however, the patient is still alive with stable disease after radiotherapy. The radiological features, management, and relevant literature are also presented. Our report heightens the awareness of PA in the adult population and the importance of close surveillance for the leptomeningeal spread, especially for sellar region tumors.

    Skin lesions of Wild Turkeys ( Meleagris gallopavo ) are a common cause of concern to wildlife biologists and the general public and are a frequent reason for submission to diagnostic laboratories. The purpose of this retrospective study is to evaluate the causes, occurrence, and epidemiologic patterns of skin lesions in Wild Turkeys in the eastern US. Skin lesions were diagnosed in 30% (n=199) of the 660 Wild Turkey samples submitted to the Southeastern Cooperative Wildlife Disease Study diagnostic service from 1975 to 2013. Avian pox was the most frequent cause of skin lesions (66%, n=131), followed by bacterial dermatitis (22%, n=44), ectoparasitism-related dermatitis (3%, n=6), fungal dermatitis (2.5%, n=5), and neoplasia (2.0%, n=4). Although the gross appearance of skin lesions is often insufficient to determine the etiology, the anatomic distribution of lesions and temporal occurrence of certain diseases may offer insights into likely causes. Cases with lesions involving or restricted to the head and neck were much more likely to be caused by avian pox than other etiologies. Similarly, lesions restricted to the feet were more likely to be of bacterial origin. Skin lesions observed in the fall and winter were more likely to be caused by avian pox, whereas bacterial dermatitis was more frequently observed in the spring and summer. This retrospective study provides a summary of the causes of skin lesions in Wild Turkeys and serves as a useful reference to diagnosticians and biologists when evaluating Wild Turkeys with skin lesions.

    To evaluate the feasibility and efficacy of US-guided preoperative wire localization of nonpalpable breast lesions. US-guided preoperative wire localization was performed upon 45 nonpalpable breast lesions including 14 nonpalpable masses, 11 nonpalpable masses with microcalcifications, 11 ductal lesions, 9 with microcalcifications. No local anesthesia was performed during the localization procedure. Under the US-guidance, the needle with the hook-wire was inserted into the lesion until the hook of the wire reached 1 cm beyond the posterior margin of the lesion. Precise wire positioning was confirmed by mammography. Specimen radiography or specimen ultrasonography was performed in all cases. US-guided preoperative wire localization was successfully achieved in all cases. The time required for US-guided wire localization was less than five minutes. All lesions were successfully removed by surgical excision. Successful removal was confirmed by specimen radiography or specimen ultrasonography, gross findings of the specimen and consistency between radiographic and pathologic findings. The histologic diagnosis of 45 lesions were 7 ductal carcinoma in situ, 8 invasive ductal carcinoma, 6 fibroadenoma, 8 intraductal papilloma, 2 atypical ductal hyperplasia, and 14 fibrocystic changes. No complications were occurred during and after the procedure. US-guided preoperative wire localization for excisional biopsy is simple, safe, and accurate method in the histologic diagnosis of nonpalpable breast lesions detectable with ultrasonography.

    In this paper, we propose a fast and reliable data dissemination protocol Cascades to disseminate data from the sink(base station) to all or a subset of nodes in a data collection sensor network. Cascades makes use of the parentmonitor-children analogy to ensure reliable dissemination. Each node monitors whether or not its children have received the broadcast messages through snooping children's rebroadcasts or waiting for explicit ACKs. If a node detects a gap in its message sequences, it can fetch the missing messages from its neighbours reactively. Cascades also considers many practical issues for field deployment, such as dynamic topology, link/node failure, etc.. It therefore guarantees that a disseminated message from the sink will reach all intended receivers and the dissemination is terminated in a short time period. Notice that, all existing dissemination protocols either do not guarantee reliability or do not terminate [1, 2], which does not meet the requirement of real-time command control. We conducted experiment evaluations in both TOSSIM simulator and a sensor network testbed to compare Cascades with those existing dissemination protocols in TinyOS sensor networks, which show that Cascades achieves a higher degree of reliability, lower communication cost, and less delivery delay. ??2009 IEEE.

  3. Strategies for Disseminating Qualitative Research Findings: Three Exemplars

    2007-09-01

    Full Text Available Assuming there are those who do pay attention to the dissemination of qualitative research findings, what can we learn from them? For this article, we searched for examples of qualitative research where findings have been disseminated beyond the journal article and/or conference presentation. The rationale for pursuing examples of how good qualitative research has been disseminated is that we pay attention to both scientific and communicative concerns. All three exemplars in this article go beyond the forms of dissemination that traditionally serve academic communities and attempt to address the communicative concern of qualitative research findings. This is not to say that these modes of dissemination replace the scholarship of qualitative research and/or the peer-reviewed journal manuscript—far from it. In disseminating qualitative data, researchers have an array of presentational styles and formats to choose from that best fit their research purposes, such as drama, dance, poetry, websites, video and evocative forms of writing. We conclude by considering the ethical issues that may be involved in these forms of disseminating qualitative research, as well as the challenges for evaluating the impact of such strategies.

  4. A Spread Willingness Computing-Based Information Dissemination Model

    2014-01-01

    Full Text Available This paper constructs a kind of spread willingness computing based on information dissemination model for social network. The model takes into account the impact of node degree and dissemination mechanism, combined with the complex network theory and dynamics of infectious diseases, and further establishes the dynamical evolution equations. Equations characterize the evolutionary relationship between different types of nodes with time. The spread willingness computing contains three factors which have impact on user’s spread behavior: strength of the relationship between the nodes, views identity, and frequency of contact. Simulation results show that different degrees of nodes show the same trend in the network, and even if the degree of node is very small, there is likelihood of a large area of information dissemination. The weaker the relationship between nodes, the higher probability of views selection and the higher the frequency of contact with information so that information spreads rapidly and leads to a wide range of dissemination. As the dissemination probability and immune probability change, the speed of information dissemination is also changing accordingly. The studies meet social networking features and can help to master the behavior of users and understand and analyze characteristics of information dissemination in social network.

    New and traditional educational media were used to study alternative methods of instruction in a human gross anatomy course. Three consecutive entry-level physical therapy (PT) classes (55 students total) participated in this study. No other anatomy course was available to these students during this time. During the first year, all entering PT students (n = 18) completed a traditional cadaver anatomy course. This traditional group attended weekly lectures and dissection laboratories for 15 weeks. During the second year, the next entering class of PT students (n = 17) completed a self-study, computerized noncadaver anatomy course. This self-study group attended an introductory session to receive course objectives and instruction in using the computer package chosen for the study. After the introductory session, this group worked independently for the remainder of their 15-week course. During the third year, the entering class of PT students (n = 20) attended weekly lectures and completed a self-study, computerized non-cadaver laboratory course. This lecture and self-study group attended an introductory session to review course objectives and receive instruction in using the computer package. For the remainder of their 15-week course, this group attended a weekly lecture and worked independently on the computer for the laboratory portion of their course. All groups kept time logs, recording class and study time for each day of the course. The time logs were collected on the last day of each course. Each group's performance in anatomy-based system courses was followed through the remainder of the PT curricula, including clinical rotations, and through the completion of the state board licensure examination. Data were analyzed using a multivariate analysis of variance and a Kruskal-Wallis analysis of variance. There was no significant difference in anatomy course class means, class study times, performance throughout the remainder of the PT curricula, and performance

  6. Disseminated intravascular coagulation in burn injury.

    2010-06-01

    Disseminated intravascular coagulation (DIC) is a complex and multifaceted disorder characterized by the activation of coagulation and fibrinolytic pathways, consumption of coagulation factors, and depletion of coagulation regulatory proteins. The introduction into the circulation of cellular debris characterized by strong thromboplastic activity due to tissue factor exposition or release (in or from burned tissues), which can thereby activate extrinsic pathway of coagulation system and trigger massive thrombin generation when present in sufficient concentration, represents the most plausible biological explanation to support the development of intravascular coagulation in patients with burn injury. Severe burns left untreated might also lead to an immunological and inflammatory response (activation of the complement cascade), which can amplify fibrinolysis and blood clotting. Overall, the real prevalence of DIC in patients with burns is as yet unclear. Postmortem, retrospective, and even longitudinal investigations are in fact biased by several factors, such as the objective difficulty to establish whether DIC might have occurred as a primary complication of burns or rather as a consequence of other superimposed pathologies (e.g., sepsis, multiple organ failure), the different diagnostic criteria for assessing DIC, and the heterogeneity of the patient samples studied. Nevertheless, the current scientific evidence is consistent with the hypothesis that biochemical changes suggestive for DIC (hypercoagulability, hypo- and hyperfibrinolysis) are commonplace in patients with burn trauma, and their severity increases exponentially with the severity of injury. Overt DIC seems to occur especially in critically ill burn patients or in those with severe burns (up to third degree) and large involvement of body surface area, in whom an appropriate therapy might be effective to prevent the otherwise fulminant course. Although early prophylaxis with antithrombin concentrates

    Full Text Available A 10-year-old domestic short hair cat was referred for investigation of anorexia and polydipsia of 3 days’ duration. Clinically the cat was obese, pyrexic (39.8 °C, had acute abdominal pain and severe bilirubinuria. Haematology and serum biochemistry revealed severe panleukopenia, thrombocytopenia, markedly elevated alanine aminotransferase (ALT and five-fold increased pre-prandial bile acids. Ultrasonographic evaluation of the abdomen did not identify any abnormalities. Serum tests for feline immunodeficiency virus (FIV and feline leukaemia virus (FeLV were negative. Broad-spectrum antibiotic treatment for infectious hepatitis was to no avail; the cat deteriorated and died 72 h after admission. Necropsy revealed mild icterus and anaemia, severe multifocal hepatic necrosis, serofibrinous hydrothorax, pulmonary oedema and interstitial pneumonia. Histopathology confirmed the macroscopic findings and revealed multifocal microgranulomata in the brain and myocardium, as well as areas of necrosis in lymph nodes and multifocally in splenic red pulp. Long bone shaft marrow was hyperplastic with a predominance of leukocyte precursors and megakaryocytes and splenic red pulp showed mild extramedullary haemopoiesis. Immunohistochemical staining for Toxoplasma gondii was strongly positive, with scattered cysts and tachyzoites in the liver, lymph nodes, spleen, lungs, brain, salivary glands and intracellularly in round cells in occasional blood vessels. Immunohistochemical staining for corona virus on the same tissues was negative, ruling out feline infectious peritonitis (FIP. Polymerase chain reaction (PCR on formalin-fixed paraffin-wax embedded tissues was positive for Toxoplasma sp., but attempts at sequencing were unsuccessful. This was the first case report of fulminant disseminated toxoplasmosis in South Africa, in which detailed histopathology in an apparently immunocompetent cat was described.

    In this paper, we consider the problem of continuous dissemination of time series data, such as sensor measurements, to a large number of subscribers. These subscribers fall into multiple subscription levels, where each subscription level is specified by the bandwidth constraint of a subscriber......, which is an abstract indicator for both the physical limits and the amount of data that the subscriber would like to handle. To handle this problem, we propose a system framework for multi-scale time series data dissemination that employs a typical tree-based dissemination network and existing time-series...

    Objective To study the MR characterizations of supraspinatus and infraspinatus tendon lesions by comparing with gross anatomy and histopathology. Methods The study group consisted of 20 cadaver shoulders which were underwent the same imaging protocols of conventional MRI and MR arthrography. Results SE-T2WI images or MR arthrography respectively possessed of high specificity (95.6%, 100%), but low sensitivity (70.6%, 58.8%) for diagnosing rotator cuff tears. By uniting two images techniques, could remedy its limitations and would markedly increase the sensitivity (88.2%). There were many factors influencing the visualizations of partial thickness tears of rotator cuff on MR images, from which uppermost factors are tear extent, ruptured synovial capsule, scar and synovial proliferation. Conclusion MRI diagnoses of rotator cuff lesions (especially partial thickness tears) must carefully be estimated by combining T2WI images and MR arthrography.

    Full Text Available Background. Thalamic lesions are seen in a multitude of disorders including vascular diseases, metabolic disorders, inflammatory diseases, trauma, tumours, and infections. In some diseases, thalamic involvement is typical and sometimes isolated, while in other diseases thalamic lesions are observed only occasionally (often in the presence of other typical extrathalamic lesions. Summary. In this review, we will mainly discuss the MRI characteristics of thalamic lesions. Identification of the origin of the thalamic lesion depends on the exact localisation inside the thalamus, the presence of extrathalamic lesions, the signal changes on different MRI sequences, the evolution of the radiological abnormalities over time, the history and clinical state of the patient, and other radiological and nonradiological examinations.

    2015-05-01

    It is shown that the world distribution of gross domestic products per capita (GDPpc) is well described by a trade-investment model that combines yard-sale (YS) exchange and random multiplicative noise (RMN). We first derive analytically the typical value w(r, t) of the ranked wealths for a system evolving under YS exchange and RMN. The resulting analytical expressions are fitted to data for the GDPpc of up to 200 countries, in the period 1960-2013. Our model fits the data significantly better than previously proposed approaches that consider either Noise or Trade alone. Analysis of the resulting values for the fitting parameters, and of their time dependence, suggests that: (a) International trade conditions have (from 1960 to 2008) a statistical bias towards favoring richer countries. (b) Biased international commerce is the main cause for the observed divergence of GDPpc values from 1960 to 2008. (c) After 2008, the distribution of GDPpc starts to converge, and the world product per capita stops growing.

Higher risk of malformed births were noticed amongst un-booked (2.07% in-comparison to booked (1.01% mothers; women with low level of education (up to 8 years [2.14%] vs. at least 9 years of schooling [0.82%]; gravida status of at least 3 (2.69% followed by 1 (1.43% and 2 (1.0% respectively; pre-term (5.13% vs. term (0.66%; cesarean section (4.36% versus vaginal delivery (0.62%. Mortality was significantly higher among congenitally malformed (17.35% than normal (0.34% newborns. With-in study limitation, emergence of neural tube defect as the single largest category of congenital malformation indicates maternal malnutrition (especially folic acid that needs appropriate attention and management.

    Long-term studies of megestrol acetate and chlormadinone acetate in 100 female dogs are in progress. Doses of zero, one, 10 and 25 times the expected human dose of megestrol acetate and 25 times the expected human dose of chlormadinone acetate (on a milligram per kilogram body weight basis) are being given daily. During the first 4 years, eight dogs from each of the five groups were killed. The principal gross findings included enlarged uteri with mucoid material in the lumina, mammary development in dogs given middle and high doses of megestrol acetate and chlormadinone acetate, and thickened gallbladder walls in dogs given high doses of each. Histologic evaluation showed inhibition of ovulation for progestogen-treated dogs and suppression of ovarian follicular development with the high doses. Cystic endometrial hyperplasia was slight in the low-dose dogs and moderate to severe in most of the high-dose dogs; a few also had ulcerative endometritis and pyometra. The mammary glands of dogs given the middle and high doses produced lobules, acini, and secretion exceeding natural metestrus. Slight to marked cystic mucinous hyperplasia occurred in the gallbladders of most dogs given the high doses. Tow high-dose megestrol dogs had clinical signs and microscopic pancreatic, renal, and ocular changes indicative of diabetes mellitus.

    Stratospheric sulfate geoengineering could impact the terrestrial carbon cycle by enhancing the carbon sink. With an 8 Tg yr-1 injection of SO2 to balance a Representative Concentration Pathway 6.0 (RCP6.0) scenario, we conducted climate model simulations with the Community Earth System Model, with the Community Atmospheric Model 4 fully coupled to tropospheric and stratospheric chemistry (CAM4-chem). During the geoengineering period, as compared to RCP6.0, land-averaged downward visible diffuse radiation increased 3.2 W m-2 (11 %). The enhanced diffuse radiation combined with the cooling increased plant photosynthesis by 2.4 %, which could contribute to an additional 3.8 ± 1.1 Gt C yr-1 global gross primary productivity without nutrient limitation. This increase could potentially increase the land carbon sink. Suppressed plant and soil respiration due to the cooling would reduce natural land carbon emission and therefore further enhance the terrestrial carbon sink during the geoengineering period. This beneficial impact of stratospheric sulfate geoengineering would need to be balanced by a large number of potential risks in any future decisions about implementation of geoengineering.

    Full Text Available Stratospheric sulfate geoengineering could impact the terrestrial carbon cycle by enhancing the carbon sink. With an 8 Tg yr−1 injection of SO2 to balance a Representative Concentration Pathway 6.0 (RCP6.0 scenario, we conducted climate model simulations with the Community Earth System Model, with the Community Atmospheric Model 4 fully coupled to tropospheric and stratospheric chemistry (CAM4-chem. During the geoengineering period, as compared to RCP6.0, land-averaged downward visible diffuse radiation increased 3.2 W m−2 (11 %. The enhanced diffuse radiation combined with the cooling increased plant photosynthesis by 2.4 %, which could contribute to an additional 3.8 ± 1.1 Gt C yr−1 global gross primary productivity without nutrient limitation. This increase could potentially increase the land carbon sink. Suppressed plant and soil respiration due to the cooling would reduce natural land carbon emission and therefore further enhance the terrestrial carbon sink during the geoengineering period. This beneficial impact of stratospheric sulfate geoengineering would need to be balanced by a large number of potential risks in any future decisions about implementation of geoengineering.

    We describe a Horava-Lifshitz-like reformulated four-fermion Gross-Neveu model describing the dynamics of two-component spinors in (2 +1 )-dimensional space-time. Within our study, we introduce the Lagrange multiplier, study the gap equation (including the finite temperature case) which turns out to display essentially distinct behaviors for even and odd values of the critical exponent z , and show that the dynamical parity breaking occurs only for the odd z . We demonstrate that for any odd z , there exists a critical temperature at which the dynamical parity breaking disappears. Besides of this, we obtain the effective propagator and show that the resulting effective theory is renormalizable within the framework of the 1/N expansion for all values of z . As one more application of the dynamical parity breaking, we consider coupling of the vector field to the fermions in the case of a simplified spinor-vector coupling and discuss the generation of the Chern-Simons term.

    Growth in terrestrial gross primary production (GPP)—the amount of carbon dioxide that is ‘fixed’ into organic material through the photosynthesis of land plants—may provide a negative feedback for climate change. It remains uncertain, however, to what extent biogeochemical processes can suppress global GPP growth. As a consequence, modelling estimates of terrestrial carbon storage, and of feedbacks between the carbon cycle and climate, remain poorly constrained. Here we present a global, measurement-based estimate of GPP growth during the twentieth century that is based on long-term atmospheric carbonyl sulfide (COS) records, derived from ice-core, firn and ambient air samples. We interpret these records using a model that simulates changes in COS concentration according to changes in its sources and sinks—including a large sink that is related to GPP. We find that the observation-based COS record is most consistent with simulations of climate and the carbon cycle that assume large GPP growth during the twentieth century (31% ± 5% growth; mean ± 95% confidence interval). Although this COS analysis does not directly constrain models of future GPP growth, it does provide a global-scale benchmark for historical carbon-cycle simulations.

    Growth in terrestrial gross primary production (GPP) may provide a feedback for climate change, but there is still strong disagreement on the extent to which biogeochemical processes may suppress this GPP growth at the ecosystem to continental scales. The consequent uncertainty in modeling of future carbon storage by the terrestrial biosphere constitutes one of the largest unknowns in global climate projections for the next century. Here we provide a global, measurement-based estimate of historical GPP growth using long-term atmospheric carbonyl sulfide (COS) records derived from ice core, firn, and ambient air samples. We interpret these records using a model that relates changes in the COS concentration to changes in its sources and sinks, the largest of which is proportional to GPP. The COS history was most consistent with simulations that assume a large historical GPP growth. Carbon-climate models that assume little to no GPP growth predicted trajectories of COS concentration over the anthropogenic era that differ from those observed. Continued COS monitoring may be useful for detecting ongoing changes in GPP while extending the ice core record to glacial cycles could provide further opportunities to evaluate earth system models.

    A 5 year-old boy presented with 2-days of fever and cough. On examination, he had mild dyspnoea and chest pain, with crackles and hypoventilation at the right lung base. Blood tests showed: WBC 39.1×10(9)/L; N 28.9×10(9)/L; Hb 11.3gr/dL; PLT 375×10(9)/L; CRP 28.7mg/dL; ESR 41mm/h. Chest x-ray confirmed a pulmonary consolidation in the right lower lobe (figure 1), with an associated pleural effusion. Bacterial pneumonia was diagnosed and intravenous ceftriaxone 100mg/kg/die was started. The following day, he developed palpebral oedema and his urine became tea coloured. His blood pressure was 126/82mmHg (>99th percentile).(1) Serum creatinine rose from 0.45mg/dl to 1.09mg/dl (39.8µmol/L - 93.4µmol/L) and C3 was 9mg/dl (n.r. 90-180mg/dl). Urinalysis revealed gross hematuria and 3+ proteinuria, with microscopicy showing dysmorphic red blood cells with casts. Ultrasounds showed enlarged kidneys with increased echogenicity. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017. All rights reserved.

    Peer-assisted learning encourages students to participate more actively in the dissection process and promotes thoughtful dissection. We implemented peer-assisted dissection in 2012 and compared its effects on students' self-assessments of learning and their academic achievement with those of faculty-led dissection. All subjects performed dissections after a lecture about upper-limb gross anatomy. Experimental group (n = 134) dissected a cadaver while guided by peer tutors who had prepared for the dissection in advance, and control group (n = 71) dissected a cadaver after the introduction by a faculty via prosection. Self-assessment scores regarding the learning objectives related to upper limbs were significantly higher in experimental group than in control group. Additionally, experimental group received significantly higher academic scores than did control group. The students in peer-assisted learning perceived themselves as having a better understanding of course content and achieved better academic results compared with those who participated in faculty-led dissection. Peer-assisted dissection contributed to self-perception and to the ability to retain and explain anatomical knowledge.

    Full Text Available Context The size of colorectal lesions, besides a risk factor for malignancy, is a predictor for deeper invasion Objectives To evaluate the malignancy of colorectal lesions ≥20 mm. Methods Between 2007 and 2011, 76 neoplasms ≥20 mm in 70 patients were analyzed Results The mean age of the patients was 67.4 years, and 41 were women. Mean lesion size was 24.7 mm ± 6.2 mm (range: 20 to 50 mm. Half of the neoplasms were polypoid and the other half were non-polypoid. Forty-two (55.3% lesions were located in the left colon, and 34 in the right colon. There was a high prevalence of III L (39.5% and IV (53.9% pit patterns. There were 72 adenomas and 4 adenocarcinomas. Malignancy was observed in 5.3% of the lesions. Thirty-three lesions presented advanced histology (adenomas with high-grade dysplasia or early adenocarcinoma, with no difference in morphology and site. Only one lesion (1.3% invaded the submucosa. Lesions larger than 30 mm had advanced histology (P = 0.001. The primary treatment was endoscopic resection, and invasive carcinoma was referred to surgery. Recurrence rate was 10.6%. Conclusions Large colorectal neoplasms showed a low rate of malignancy. Endoscopic treatment is an effective therapy for these lesions.

    Full Text Available Biopsies from human localized cutaneous lesions (LCL n = 7 or disseminated lesions (DL n = 8 cases were characterized according to cellular infiltration,frequency of cytokine (IFN-g, TNF-alpha or iNOS enzyme producing cells. LCL, the most usual form of the disease with usually one or two lesions, exhibits extensive tissue damage. DL is a rare form with widespread lesions throughout the body; exhibiting poor parasite containment but less tissue damage. We demonstrated that LCL lesions exhibit higher frequency of B lymphocytes and a higher intensity of IFN-gamma expression. In both forms of the disease CD8+ were found in higher frequency than CD4+ T cells. Frequency of TNF-alpha and iNOS producing cells, as well as the frequency of CD68+ macrophages, did not differ between LCL and DL. Our findings reinforce the link between an efficient control of parasite and tissue damage, implicating higher frequency of IFN-gamma producing cells, as well as its possible counteraction by infiltrated B cells and hence possible humoral immune response in situ.

    The aim of the examination was to gain knowledge on the incidence of Chamaeleomyces granulomatis mycosis in Veiled chameleons (Chamaeleo calyptratus), a disease which has recently been described as a single outbreak in a zoo collection. During a time period of 26 months (September 2009-November 2011) 18 Veiled chameleons presented at the clinic for various reasons were examined for the presence of C. granulomatis. Swabs were taken from tongue and skin lesions of live chameleons and from internal granulomas of deceased chameleons. Mycological culture was performed on Sabouraud dextrose and Potato dextrose agar as described previously. For the first time, the obtained isolates were screened for susceptibility towards different antifungal drugs by use of agar diffusion testing. Fungal species were determined by amplification with different primers, as reported before, and sequencing of parts of the 28S rDNA gene, the 18S rDNA gene, internal transcribed spacer region-1 DNA and 5.8S rDNA gene. Ten cases of disseminated mycosis caused by C. granulomatis were thus documented. These animals were kept in nine different collections of differing owners. Common findings in diseased chameleons were disseminated mycosis, glossitis and dermatitis. Although all isolates were tested sensitive to terbinafine and nystatin. The results of this study clearly show, contrary to a recently published single outbreak in a zoo collection, that disseminated mycosis caused by C. granulomatis in Veiled chameleons is, a common and often fatal infectious disease in this species. The routes of infection or treatment options are still unknown and need further investigation.

    X-ray picture has been analysed in patients of 2 groups. The 1st group included 120 patients with disseminated tuberculosis, the 2 nd one 56 patients with systemic diseases (lupus erythematosus and scleroderma). The disease initial diagnosis was erroneous in 8 cases (4.5%), i.e. in 5 patients tuberculosis was unrecognized, and in 3 the systemic disease. It is marked, that x-ray pulmonary alterations bore interstitial character in collagenoses, and focal in tuberculosis. Predominant apical posterior lung segment lesion was detected in 95% of cases in tuberculosis, while caverns were diagnosed in 65.8%. Besides, radiographic features of the gastrointestinal tract, the skeleton, and the heart damage were established in 82.9% of systemic scleroderma patients.

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

    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.

    Multiple tuberculous mycobacterial infections infrequently occur in immunocompromised patients. The malnutrition resulted from anorexia nervosa may contribute to the significant impairment of immunity. The authors present a 23-year-old female patient initially diagnosed with anorexia nervosa. Immunological study revealed that helper T-cell (CD4) and cytotoxic T-cell (CD8) comprised 25 and 32%, respectively, with a CD4 to CD8 ratio of 0.78. Brain magnetic resonance imaging revealed various multiple rings enhancing lesions with edematous change in both cerebral and cerebellar hemispheres. Open biopsy disclosed palisading epithelioid granuloma surrounded by inflamed granulation tissue. After anti-tuberculous therapy for 12 months, her weight was completely restored, but multiple intracranial tuberculomas were not completely disappeared. Disseminated tuberculous mycobacterial infections including multiple intracranial tuberculomas may be attributed to immunocompromised status in anorexia nervosa.

  12. Significance of Micrometastases: Circulating Tumor Cells and Disseminated Tumor Cells in Early Breast Cancer

    2010-06-01

    Full Text Available Adjuvant systemic therapy targets minimal residual disease. Our current clinical approach in the adjuvant setting is to presume, rather than confirm, the presence of minimal residual disease. Based on assessment of the primary tumor, we estimate an individual’s recurrence risk. Subsequent treatment decisions are based on characteristics of the primary tumor, with the presumption of consistent biology and treatment sensitivity between micrometastases and the primary lesion. An alternative approach is to identify micrometastatic disease. Detection of disseminated tumor cells (DTC in the bone marrow and circulating tumor cells (CTC from peripheral blood collection may offer quantification and biocharacterization of residual disease. This paper will review the prognostic and predictive potential of micrometastatic disease in early breast cancer.

    Leishmaniasis is emerging as a common and serious opportunistic disease for patients with HIV infection. Almost all cases of HIV-Leishmania coinfection have been described in Mediterranean countries and they occur with various clinical presentations, ranging from typical visceral forms to asymptomatic or atypical cases, including cutaneous and mucocutaneous leishmaniasis. Pentavalent antimony compounds have been the mainstays of antileishmanial therapy for half a century and new lipid formulations of amphotericin B seem reliable, but the most effective treatment remains unknown. We describe a patient who was HIV infected and an intravenous drug user, with an unusual disseminated cutaneous leishmaniasis, after an initial visceral disease and after a 13-month maintenance treatment with liposomal amphotericin. The severe concurrent immunosuppression probably played an essential role in leading to this atypical cutaneous form, characterized by diffuse, nonulcerated, nonscabby maculopapular lesions.

    To conceptualise and discuss dissemination bias in qualitative research. It is likely that the mechanisms leading to dissemination bias in quantitative research, including time lag, language, gray literature, and truncation bias also contribute to dissemination bias in qualitative research. These conceptual considerations have informed the development of a research agenda. Further exploration of dissemination bias in qualitative research is needed, including the extent of non-dissemination and related dissemination bias, and how to assess dissemination bias within qualitative evidence syntheses. We also need to consider the mechanisms through which dissemination bias in qualitative research could occur to explore approaches for reducing it. Copyright © 2017 Elsevier Inc.

    2012-01-01

    We investigate the use of network coding for information dissemination over a wireless network. Using network coding allows for a simple, distributed and robust algorithm where nodes do not need any information from their neighbors. In this paper, we analyze the time needed to diffuse information throughout a network when network coding is implemented at all nodes. We then provide an upper bound for the dissemination time for ad-hoc networks with general topology. Moreover, we derive a relation between dissemination time and the size of the wireless network. It is shown that for a wireless network with N nodes, the dissemination latency is between O(N) and O(N^2), depending on the reception probabilities of the nodes. These observations are validated by the simulation results.
