Повний текст джерелаENGLISH ABSTRACT: Planar bone scintigraphy is highly sensitive but it may not be sensitive enough to detect subtle lesions in complex bony structures such as the spine. The accurate anatomic localisation of lesions in regions such as this is also limited using planar images. Single Photon Emission Computed Tomography (SPECT) results in a higher lesion contrast resulting in an improved sensitivity for the detection of subtle lesions. SPECT also enables improved lesion localisation, often valuable in distinguishing benign from malignant disease in the spine. A number of previous studies have demonstrated that the addition of SPECT of the spine significantly enhances the value of bone scintigraphy for the detection of bone metastases compared to planar imaging alone. These studies were however not done in the African context where patients typically present with more advanced disease. In a retrospective study of 576 patients with known primary tumors sent to our institution for bone scintigraphy for the diagnosis of bone metastases, we evaluated 119 patients in whom both planar imaging and SPECT were obtained. The studies were graded for the probability of metastatic disease, and the number of spinal lesions was determined with and without SPECT. The influence of adding SPECT on the interpretation of the study was determined in terms of the reported probability of metastatic disease, the exclusion and confirmation of metastatic disease, the decisiveness of interpretation, and the number of spinal lesions. The addition of SPEeT resulted in a statistically significant change in the interpretation of studies, although the actual numbers of patients affected were relatively small. SPEeT resulted in a more decisive interpretation of bone scintigraphy. There was a significant increase in the number of spinal lesions detected after the addition of SPEeT. It was concluded that although the use of SPEeT is ideal, acceptable results could be achieved using planar imaging alone in this patient population. This is particularly relevant in the African context, where SPEeT is often unavailable or scarce and in great demand.
AFRIKAANSE OPSOMMING: Planare beenflikkergrafie is hoogs sensitief, maar moontlik nie sensitief genoeg om subtiele letsels in ingewikkelde beenstrukture soos die werwelkolom aan te toon nie. Akkurate anatomiese lokalisasie van letsels in die genoemde strukture is beperk wanneer slegs planare beelde gebruik word. Enkelfoton-uitstraling Rekenaartomografie (EFERT) lewer 'n hoër letsel kontras, wat 'n verbeterde sensitiwiteit vir die opsporing van subtiele letsels tot gevolg het. EFERT lei ook tot verbeterde letsel lokalisasie, wat dikwels van waarde is om onderskeid tussen benigne en maligne siekte in die werwelkolom te tref. Reeds met 'n aantal vorige studies is aangetoon dat die toevoeging van EFERT van die werwelkolom die waarde van beenflikkergrafie in die opsporing van beenmetastases beduidend verhoog bo dié van planare beelding alleenlik. Hierdie studies is egter nie in omstandighede eie aan Afrika gedoen nie, waar pasiënte kenmerkend met gevorderde siekte voordoen. In In terugskouende studie van 576 pasiënte met bekende primêre tumore, wat na ons instelling verwys is vir beenflikkergrafie om beenmetastases op te spoor, het ons 119 pasiënte, wat beide planare beelding en EFERT ondergaan het, ge-evalueer. Die studies is gegradeer volgens die waarskynlikheid vir metastatiese siekte, en die hoeveelheid werwelkolom letsels, met en sonder EFERT, is bepaal. Die invloed van EFERT op die vertolking van die studie is bepaal in terme van die waarskynlikheid van metastatiese siekte, die bevestiging en uitskakeling daarvan, die beslistheid van vertolking, en die hoeveelheid werwelkolom letsels. Die toevoeging van EFERT het tot 'n statisties beduidende verandering in die vertolking van studies gelei, alhoewel die werklike getal pasiënte wat hierdeur geraak is, relatief min was. EFERT het 'n meer besliste vertolking van beenflikkergrafie tot gevolg gehad. Daar was 'n beduidende toename in die hoeveelheid werwelkolom letsels wat opgespoor is na die toevoeging van EFERT. Daar is tot die slotsom gekom dat, alhoewel die gebruik van EFERT wenslik is, aanvaarbare resultate met slegs die gebruik van planare beelding in hierdie pasiënt bevolkingsgroep verkry kan word. Dit is veral van belang in Afrikaomstandighede, waar EFERT dikwels onbeskikbaar of skaars is, en ook in groot aanvraag is.

Повний текст джерелаThe correct identification of diseases is fundamental for the construction of the biological profile of forensic and archaeological cases. The diagnosis of bone diseases consists in the comparison of the location and morphological characteristics of bone changes with the clinical literature and previous published cases for the identification of the causative agent. While the clinical literature may not be adequate to understand the morphology and distribution of dry bone lesions, the current paleopathological literature is mostly based on archaeological skeletons, on which very little is known, and specimens from pathology museums, with extreme manifestations of diseases often unrepresentative of classic cases. This thesis aims to investigate the macroscopic diagnosis of pathological conditions based on skeletons with antemortem clinical diagnoses from a reference osteological collection: the CAL Milano Cemetery Skeletal Collection, and in particular atherosclerosis, rheumatoid arthritis, diabetes mellitus, HIV/AIDS, multiple myeloma and solid metastatic cancer. In addition to this main objective, several other research lines were explored including the histological analysis of non-skeletal calcified manifestations of diseases, the comparison between macroscopic and radiographic analysis of bone lesions and the description of bone lesions for pathological analysis on dry bones, through the examination of skeletal material from cemeterial, forensic and archaeological cases as well as samples extracted from well- preserved cadavers during autopsies. This research not only implemented the scientific literature on bone diseases but also provided specific documentation to diagnose conditions previously unexamined and raised some important issues on the diagnosis of skeletal conditions on dry bone.

p = ,016), total work in extension (r = ,28
p = ,030) and total work in flexion (r = ,27
p = ,041) in the dominant arms. The correlation between muscle strength and BMD was not significant in the non-dominant arm. The highest correlation between natural frequency and bone geometry parameters was observed in cortical thickness (r = ,82
p = ,02). A statistically significant positive correlation (r = ,81
p = ,04) was also observed between average BMD measured by QCT and by DEXA. In summary, according to the findings of this study, it can be concluded that vibration analysis is a precise method in predicting bone strength that depends highly on its size, shape and the distribution of its trabecular and cortical components.

Повний текст джерелаThe Bone Marrow Examination (BME) permits cytological assessment of Marrow, being useful in the diagnosis and monitoring of hematological disorders, when simpler tests are not sufficient to clarify the clinical picture. Are required at least two colors (Romanowsky and Prussian blue), it should be evaluated the quality of the sample, the same overall cellularity, differential count of nucleated cells, myeloid:erythroid (M:E) ratio and carefull evaluation quantitative / qualitative from the three lineages of hematopoietic (granulocytic, erythrocytic and megakaryocytic). The BME provides information relevant to diagnosis and follow-up of leukemia/lymphoma, multiple myeloma (MM), myelodysplastic syndrome (MDS), marrow aplasia, bone marrow (BM) metastatic disease , infections in HIV positive, pyrexia of unknown origin and investigation of cytopenias. The 2008 classification of the World Health Organization (WHO) to the myeloid neoplasms and acute leukemia highlight the importance of join cytogenetic findings - bring out currently FLT3, KIT, NPM1 and CEBPA gene mutations - to the morphologic, immunophenotypic, cytochemical and clinical findings reaching this way accurate diagnostic and prognostic markers that serve as a guide to effective treatment. This study aims to identify the main indications for the BME at HCPA and to verify their accuracy. It were analyzed 400 patients submitted to BME in the Hematology Unit of HCPA in the period January to December 2009, having been rescued the bone marrow aspirate results as well as all relevant clinical and laboratory data obtained from the medical records. It was found that about half of patients submit BME in our center are to control treatment, which agrees with the characteristics of it, it is a regional referral center for treatment of malignancies. In patients who perform the test with diagnostic purpose the main indications were suspected leukemia and MM. In 260 patients with suspected primary hematological disease 61.2% turned out to be the case, the remaining 38.8% had quantitative and/or qualitative BM alterations (29.6%), normal MO (6.5%) and insufficient sample or diluted (2.7%). Of the patients who took the exam with diagnostic purpose 20.5% had no biopsy. With respect to accuracy of indication, it was found that 7 patients (2%) probably should not have undergone this procedure. We emphasize the importance of performing in all cases aspirate and biopsy since their findings must be correlated and furthermore if the biopsy is omitted the pathologist can not get the maximum information required.

Повний текст джерелаThe aim of this thesis was to study the distribution, determinants and consequences of time to diagnosis of cancer in children, through a systematic review of the literature and an analysis of lawsuits in France and Canada, and two population-based studies of tumors with particularly long diagnosis delays: medulloblastoma and Ewing sarcoma.The systematic review did not identify any significant decreases in time to diagnosis during the studies. Long times to diagnosis were associated with older age, histological type and location of the tumor. Associations between time to diagnosis and severity of the disease varied. Only a third of the court-appointed experts (n = 56) provided testimony concordant with the available medical literature.The median time to diagnosis of children with medulloblastoma in the area of Paris (n = 166) was 65 days. Diagnosis delays were paradoxically associated with less frequent metastasis and favorable histology, but not with survival, or sequelae.The median time to diagnosis of children with Ewing sarcoma in France (n = 436) was 70 days. Diagnosis delays, related with older age and tumor location, were not associated with tumor size, presence of metastasis, surgical outcome, or survival.For some tumors, an association between time to diagnosis and severity of the disease is well established (e.g. retinoblastoma), or highly probable. For others, the lack of demonstrated associations could tone down the perception of the supposed consequences of diagnosis delays - but does not exempt from trying to reduce them, in order to alleviate their psychological consequences

Повний текст джерелаTiivistelmä Nivelrikko on maailman yleisin nivelsairaus. Se aiheuttaa merkittävää kärsimystä potilaille, ja sillä on suuri taloudellinen vaikutus yhteiskuntaan. Nivelrikko aiheuttaa palautumattomia muutoksia nivelrustokudoksen ja rustonalaisen luun koostumukseen ja rakenteeseen. Nivelrikon diagnoosi perustuu kliiniseen tutkimukseen ja röntgenkuvien silmämääräiseen arviointiin. Nykyiset nivelrikon kliiniset kuvantamismenetelmät ovat subjektiivisia eivätkä riittävän tarkkoja nivelrikon varhaisten muutosten osoittamiseen, minkä vuoksi rustokudoksen koostumuksen ja rustonalaisen luun muutosten arviointiin tarvitaan uusia menetelmiä. Tämän väitöskirjantyön tarkoituksena oli tutkia uusien röntgensäteilyyn perustuvien menetelmien soveltuvuutta polvinivelen rustokudoksen proteoglykaanipitoisuuden sekä luun tiheyden ja rakenteen arviointiin. Rustonalaisen luun tiheyttä ja rakennetta arvioitiin digitaalisesta röntgenkuvasta tietokonepohjaisilla menetelmillä ja tuloksia verrattiin mikrotietokonetomografiassa nähtävään luun kolmiulotteiseen rakenteeseen. Röntgenkuvasta laskettavia muuttujia verrattiin myös eriasteisesta nivelrikosta kärsivien henkilöiden välillä. Rustokudoksen proteoglykaanipitoisuutta epäsuorasti mittaavaa tietokonetomografiamenetelmää verrattiin vastaavaan magneettikuvausmenetelmään henkilöillä, jotka olivat menossa polven niveltähystykseen. Röntgenkuvasta laskettu rustonalaisen luun tiheys ja rakenne olivat tilastollisesti selkeästi yhteydessä luun tilavuusmäärään ja mikrorakenteeseen, ja ne erosivat eriasteisesta nivelrikosta kärsivien henkilöiden välillä. Proteoglykaanipitoisuutta arvioivien tietokonetomografia- ja magneettikuvausmenetelmien välillä oli tilastollisesti merkitsevä korrelaatio. Ruston proteoglykaanipitoisuutta arvioivan magneettikuvausmenetelmän ja röntgenkuvasta laskettavan luun rakenteen välillä oli myös tilastollinen yhteys. Loppupäätelmänä voidaan todeta, että luun tiheyttä ja rakennetta on mahdollista arvioida kliinisesti saatavilla olevista röntgenkuvista. Tietokonetomografiamenetelmän käyttöä tulee harkita tutkimuksissa silloin, kun rustokudoksen tilasta halutaan kolmiulotteista tietoa

Повний текст джерелаInfective endocarditis is a serious disease affecting around 2000 patients in France and 17000 in the United-States. Despite therapeutic progress, in-hospital mortality remains high, around 20%. This is mainly the consequence of a too late diagnosis and insufficiencies in the risk stratification. In fact, novel perspectives on the management of endocarditis are emerging and offer a hope for decreasing the rate of residual deaths by accelerating the process of diagnosis and risk stratification, a reduction of delays of instauration of antimicrobial therapy, the rapid transfer of high-risk patients to specialised medio-surgical centres, the development of new surgical modalities, and close long-term follow-up.Since many years, we have developed, in our institution, a research program based on a close collaboration between the researchers of the UMR 6236-CNRS and the physicians and the surgeons of the Cardiology and Cardiac Surgery Departments. This thesis reports the results of this translational research on the management of endocarditis. We have demonstrated that the standardization of the diagnostic process and of the surgical indications reduces infective endocarditis-related mortality in infective endocarditis. To improve the management, innovations such as the use of new biomarkers represent a critical new approach for this disease. From a transcriptional based approach, we have identified several new genes strongly involved in the pathophysiology of infective endocarditis. Thus, our works shows that the matrix metalloproteinase-9, S100A11 and aquaporin-9 would be potential new biomarkers for the diagnosis and the prediction of complications during infective endocarditis

Повний текст джерелаTo protect the environment and for health reasons, wastewaters are collected and directed to wastewater treatment plants (WWTPs) to be treated and purified before being reintroduced into the natural environment. Among the different biological sludge treatment schemes resulting from WWTPs, the composting process, which represents 36% in France, allows the production of a stabilized and hygienized substrate (or product), rich in nutrients.The work carried out in this study falls within this context by presenting a diagnosis of the fermentation step of a co-composting process for biological sludge located within the WWTP of Aureilhan (France, Hautes Pyrénées). The main objective was to guarantee a high quality compost by studying the fermentation step. The response to this main objective was obtained by undertaking a diagnosis based on two approaches: experimental and digital. Experimental measurements focused on the evaluation of the duration of the fermentation step (study performed on 19 compost piles), the over time measurement of temperatures as a function of the depth and length of the compost pile on four different compost pile (three in winter conditions and one in summer conditions), the determination of their initial humidity and the estimation of the sludge / structuring agent ratio.This experimental work showed : - optimal initial humidities for the fermentation step (between 50% and 70%) ;- a sludge / structuring agent ratio (between 1/7 and 1/4) lower than the theoretical one (1/3) ;- short fermentation times (less than 3 weeks) with regards to the recommendations (between 4 and 6 weeks) ;- temperatures in the compost pile insufficiently high to reach compost hygienization.These two last results made it possible to conclude that some compost piles did not undergo sufficient organic matter biodegradation during the fermentation step, which makes it possible to reactivate biodegradation on the maturation area not equipped with aeration and deodorization system.A 2D unsteady digital model was then performed. This model takes into account the real dimensions of the compost pile at the industrial site, the characteristics of the aeration system of the fermentation process, the weather conditions and the initial properties of the sludge/bark mixture. This model made it possible to show the significant impact of carrying out the fermentation step in a facility which is semi-open to the external environment. Indeed, a too low initial temperature of the windrow (lower than 10°C) resulting from winter conditions can strongly limit the development of microorganisms and therefore biodegradation reactions. Thermal losses are increased by winter conditions, in particular for compost pile areas close to the outside environment. The compost pile aeration speed is non-uniform and varies considerably depending on the length of the ventilation duct under the compost pile (estimated speed between 0.035 and 0.3 m.s-1), which leads to non-homogeneous operating conditions (oxygen availability, temperature), resulting in a heterogeneous organic matter biodegradation within the same compost pile.In the COVID-19 health crisis period, for which hygienization of sludge is important, results obtained in this study can give operators working in composting platforms compliant with those of Aureilhan, means of quickly identifying compost piles with a low temperature change and acting accordingly, for example by manipulating the adjustable ventilation sequences in order to ensure a good hygienization

Introduction: Resulting from changes in bone remodeling process osteoporosis affects a large segment of the adult population. According to Ministry of Health data in Brazil are spent on average with hip fractures due to osteoporosis, 28 million reais per year. The gold standard for diagnosis and DXA (Dual Energy X-ray Absorptiometry) but doubts remain whether the BMD (Bone Mineral Density) by means of this standard is the best way to diagnose osteoporosis and predict fracture risk. Objectives: Make an osteoporosis on review article entitled "Physiology of Osteoporosis. Establish the sensibility of ultrasound in screening for osteoporosis from Ultrasonometry the calcaneus (USQC) in relation to the gold standard DXA. Establish the sensitivity of ultrasonography in screening for osteoporosis based on bone quality by Ultrasonometry Phalange (USQF) in relation to the gold standard DXA. Establish the sensitivity of ultrasonography in screening for osteoporosis based on bone quantity of USQF in relation to the gold standard DXA. Methods: A survey was conducted in PUBMED, MEDLINE, BVS / LILACS with the key words: osteoporosis, epidemiology and pathophysiology. We selected 80 articles and after reading these, we selected 25 articles published in the last 10 years. For diagnostic tests used a descriptive study consists of sample of 125 women between 30 and 90 years who underwent screening BMD through USQC, in the period between 13 and 23 May 2013 and after accepting participate and sign the Informed Consent and were referred to the realization of USQF and the gold standard DXA spine and femur Results: At USQC in relation to the column of DXA: S=16%, E=97%, VPP=57%, VPN=82% and accuracy of 80% in relation to the femur DXA: S=42,8%, E=97%, VPP=43%, VPN=96% and accuracy of 93%. In bone quality UBPI (Ultrassoud and Bone Profile Index) versus column DXA: S=68%, E=82%, VPP=48%, VPN=91% and accuracy of 79% and the femur DXA: S=77%, E=75%, VPP=17%, VPN=99% and accuracy of 76%. Bone quantity USQF relative to Column DXA: S=77% E=83%, VPP=54%, VPN=93 and accuracy of 81% and in relation to the femur DXA: S=100%, E=75%, VPP=19%, VPN=100% and accuracy 76%. Bone quantity USQC relative to USQF: S=14%, E=95.5%, VPP=50%, VPN=74% and accuracy of 72%. Discussion: Diagnostic tests are used to assess the commitment of the skeleton and check the presence of bone deterioration. The quantitative diagnostic test of calcaneal ultrasound compared to the column DXA and femur showed little sensitive to identify bone deterioration considering that the sample included women outside the risk group and this test is effective when carried out in over 60 patient years. The quality parameter UBPI and bone quantity USQF demonstrated to be sensitive and specific, especially in relation to the femur DXA with sensibility equal to the gold standard. Conclusion: The ultrasound of calcaneus had no relevance in screening or diagnosis of osteoporosis as compared to the gold standard DXA spine and femur in this study. The phalanx of Ultrasonography considering bone quality was an important factor in the screening or diagnosis of osteoporosis, especially when compared to the femur DXA. The phalanx ultrasound quantification of bone mass had relevance to the evaluation or diagnosis of osteoporosis column and especially in the femoral osteoporosis.
Introdução: Resultante de alterações do processo de remodelagem óssea a osteoporose afeta grande segmento da população adulta. De acordo com os dados do Ministério da Saúde, no Brasil são gastos, em média, com fraturas de quadril por osteoporose, 28 milhões de reais por ano. O método padrão-ouro para o diagnóstico é o DXA (Dual Energy X-ray Absorptiometry), porém persistem dúvidas se a DMO (Densidade Mineral Óssea) por meio deste padrão é a melhor maneira de se diagnosticar osteoporose e prever riscos de fraturas. Objetivos: Fazer um artigo de revisão sobre osteoporose com o título “Fisiologia da Osteoporose”. Estabelecer a sensibilidade da ultrassonografia no rastreamento da osteoporose a partir da Ultrassonometria pelo Calcâneo (USQC) em relação ao padrão-ouro DXA. Estabelecer a sensibilidade da ultrassonografia no rastreamento da osteoporose, baseado na qualidade óssea através da Ultrassonometria de Falange (USQF) em relação ao padrão-ouro DXA. Estabelecer a sensibilidade da ultrassonografia no rastreamento da osteoporose, baseado na quantidade óssea da USQF em relação ao padrão-ouro DXA. Métodos: Foi realizada uma pesquisa nas bases de dados PUBMED, MEDLINE, BVS/LILACS com os descritores: osteoporose, epidemiologia e fisiopatologia. Foram selecionados 80 artigos e destes, após leitura, foram selecionados 25 artigos publicados nos últimos 10 anos. Para os testes diagnósticos utilizou-se um estudo descritivo composto por amostra de 125 mulheres entre 30 e 90 anos que realizaram rastreamento da DMO através do USQC, no período entre 13 e 23 de maio de 2013, e após aceitar participar da pesquisa e assinar o TCLE, foram encaminhadas para a realização da USQF e o padrão-ouro DXA de coluna e fêmur. Resultados: Na USQC em relação ao DXA de coluna: S=16%, E=97%, VPP=57%, VPN=82% e Acurácia de 80% e em relação ao DXA de fêmur: S=42,8%, E=97%, VPP= 43%, VPN=96% e Acurácia de 93%. Na qualidade óssea do UBPI (Ultrassoud and Bone Profile Index) em relação ao DXA de coluna: S=68%, E=82%, VPP= 48%, VPN=91% e Acurácia de 79% e em relação ao DXA de fêmur: S=77%, E=75%, VPP=17%, VPN=99% e Acurácia de 76%. Na quantidade óssea da USQF em relação ao DXA de coluna: S=77%, E=83%, VPP=54%, VPN=93 e Acurácia de 81% e em relação ao DXA de fêmur: S=100%, E=75,%, VPP=19%, VPN=100% e Acurácia=76%. Na quantidade óssea da USQC em relação ao USQF: S=14%, E=95,5%, VPP=50%, VPN=74% e Acurácia de 72%. Discussão: Os testes diagnósticos servem para avaliar o comprometimento do esqueleto e verificar a presença de deterioração óssea. O teste diagnóstico quantitativo da ultrassonografia de calcâneo quando comparada ao DXA de coluna e fêmur mostrou-se pouco sensível para identificar deterioração óssea. O parâmetro de qualidade UBPI (Ultrassoud and Bone Profile Index) e o de quantidade óssea da USQF demonstraram ser sensíveis e específicos, principalmente em relação ao DXA de fêmur com sensibilidade igual ao padrão-ouro. Conclusão: A ultrassonografia de calcâneo não teve relevância no rastreamento ou no diagnóstico da osteoporose quando comparado ao padrão-ouro DXA de coluna e fêmur, neste estudo. A ultrassonografia de falange considerando a qualidade óssea mostrou-se importante no rastreamento ou diagnóstico da osteoporose, especialmente quando comparada ao DXA do fêmur. A ultrassonografia de falange na quantificação da massa óssea teve relevância na avaliação ou diagnóstico da osteoporose de coluna e em especial na osteoporose de fêmur.
