    Elastography: A New Ultrasound Technique in Nodular Thyroid Pathology

    Get PDF
    Elastography is a new technique for evaluating the stiffness of nodules. It is generally recognised that malignant thyroid lesions are harder than benign lesions. Different elastographic techniques are presented, with characteristics, advantages and limitations. Qualitative and semiquantitative methods are described. Comparison of the main existing techniques, static and dynamic elastographies, is presented in this chapter. Strain elastography seems to have a better diagnostic quality than shear wave elastography in the diagnosis of thyroid cancer disease. A positive elastogram, suggestive for malignancy is more useful in diagnosis than a positive grey-scale ultrasound evaluation. Elastography increases the specificity of grey scale ultrasound (US), it should be always integrated with its information and should be considered as a complement of conventional US

    The objective of this study is to evaluate the out of plane behavior of a masonry infill wall provided with an exterior thermal insulation system. For this purpose there were constructed two 1:1 scale specimens of masonry infill walls in order to compare a simple wall with one having already applied an exterior thermal insulation system composed by a polystyrene insulation and a protection layer of plaster and a glass fiber mesh. The load was applied through a horizontal force, acting at the mid height of the wall. Both specimens were tested in displacement control, using alternate force with 3 cycles per loading step. As it was expected, an increased stiffness and out of plane resistance was observed for the wall provided with the insulation system. Various observations were noticed related to the technology and overall behavior of the infill masonry wall

    Normal testosterone level is influencing all the steps of the male psychosexual development: intrauterine neonatal and final psychosexual development.. At pubertal stage, the quality of testosterone secretion is conditioning the development of the mature male phenotype. In adult life, eugonadism sustains desire, arousal, determines spontaneous erections, facilitates stimulated erection, influencing the response rate to medication. Moreover, eugonadism sustain daydreaming and phantasies, both needed for a normal sexual life. The pathogenic mechanism of all these actions is presented. Talking about hypogonadism means not only the classical types of hypogonadism: due to classical testicular disease of central, hypothalamic and hypophysis disease, but also the partial testosterone deficiency induces by aging (late onset hypogonadism), weight increase (up to 30% of males with metabolic syndrome and 50% of males with diabetes) or secondary hypogonadism described in chronic use of steroids or after long exposure to stress, especially in young males. All these types of hypogonadism, that affect young, middle aged or old males will be presented separately. A therapeutic approach that is individualized for each type of hypogonadism, should consider positive and possible negative effects and all alternatives will be presented: life style changes, sustained weight loss, increase exercise, supplemental therapy, pro fertility treatment

    UniversitĂ© de MĂ©decine et de Pharmacie ”Victor Babes”, Timisoara, Roumanie The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Introduction: L’élastographie mammaire est une technique rĂ©cente utilisĂ©e en complĂ©ment de l’échographie mammaire dans le dĂ©pistage du cancer du sein. L’élastographie fournit non seulement des informations qualitatives (carte Ă  codage de couleur), ainsi que quantitative, liĂ©e au rapport d’élasticitĂ© du nodule versus le tissu adipeux (FLR). À la lumiĂšre de la qualitĂ©, il y a controverse sur la valeur de discrimination entre les lĂ©sions bĂ©nignes et malignes. Actuellement, la limite utilisĂ©e dans notre centre est la valeur mĂ©diane de 4,88, validĂ©e sur une Ă©tude comparative avec l’examen histopathologique, une valeur qui assure une sensibilitĂ© de 86,5% et une spĂ©cificitĂ© de 90,4% MatĂ©riel et mĂ©thodes: L’étude a inclu 344 femmes, ĂągĂ©es de 19 Ă  76 ans, avec des pathologies mammaires chirurgicales, qui ont eu un rĂ©sultat histopathologique clair et, dans certains cas, un rĂ©sultat immunohistochimique clair. RĂ©sultats: Sur le total de 344 cas, ont Ă©tĂ© diagnostiquĂ©s lĂ©sions bĂ©nignes en 186 (54,1%), le cancer du sein dans 158 cas (45,9%). Lorsque nous avons examinĂ© la valeur FLR, on a eu la stratification du risque suivant: faible risque dans 166 cas, 38 cas avec risque intermĂ©diaire et Ă  haut risque 138 cas. La sensibilitĂ© et la spĂ©cificitĂ© de cette stratification considĂ©rĂ©e isolĂ©e, sans l’information fournie par l’échographie 2B, est 92,4% et respectivement 83,9%. Le systĂšme conventionnel BIRADS-US n’avait qu’une sensibilitĂ© de 75,6%, avec une spĂ©cificitĂ© de 69,9%. Contrairement Ă  cela, un nombre important de cas classĂ©s comme intermĂ©diaires, 97 cas (catĂ©gorie BIRADS 4 a), ont Ă©tĂ© rĂ©organisĂ©s dans l’autre catĂ©gorie de risque, alors quand ils ont Ă©tĂ© soumis Ă  l’évaluation Ă©lastographique, 23 ont Ă©tĂ© attribuĂ©s Ă  un groupe Ă  haut risque en raison de l’anĂ©lasticitĂ© et 26 ont Ă©tĂ© attribuĂ©s Ă  classe de risque faible parce que l’élasticitĂ© Ă©tait prĂ©sente. Seuls 48 cas sont restĂ©s dans la catĂ©gorie intermĂ©diaire. Conclusions: Évidemment, l’élastographie apporte un plus pour l’échographie classique, en rĂ©duisant le nombre de rĂ©sultats faux positifs et faux nĂ©gatifs par rapport Ă  l’échographie classique

    Victor Babes University of Medicine and Pharmacy, Timisoara, Romania, The IVth Congress of Radiology and Medical Imaging of the Republic of Moldova with international participation, Chisinau, May 31 – June 2, 2018Introduction: L’élastographie en temps rĂ©el est une mĂ©thode de diagnostic qui ajoute de la qualitĂ© dans le diagnostic des lĂ©sions nodulaires thyroĂŻdiennes. La mĂ©ta-analyse actuelle suggĂšre une bonne performance diagnostique avec une spĂ©cificitĂ© gĂ©nĂ©rale de 80% et une sensibilitĂ© gĂ©nĂ©rale de 85%. La prĂ©sente Ă©tude est une analyse rĂ©trospective des causes les plus frĂ©quentes de faux negatifs et faux positifs rĂ©sultats rencontrĂ©s dans l’échographie thyroĂŻdienne. MatĂ©riel et mĂ©thodes: Nous avons analysĂ© 433 des lĂ©sions nodulaires, opĂ©rĂ©s et Ă©valuĂ©es par l’échographie de la thyroĂŻde classique et l’élastographie, avec la mĂȘme sonde linĂ©aire, multifrĂ©quence, Hitachi Preirus machine, Hitachi Inc., Japon. Les rĂ©sultats de l’échographie n’ont pas Ă©tĂ© communiquĂ©s au pathologiste. Une analyse rĂ©trospective des rĂ©sultats a Ă©tĂ© rĂ©alisĂ©e. RĂ©sultats: Nous avons Ă©valuĂ© 433 cas avec des nodules avec un volume moyen de 2,14 ml (allant de 0,78 ml Ă  10,45 ml). 134/433 cas ont Ă©tĂ© identifiĂ©s avec un cancer de la thyroĂŻde, 251/434 Ă©tant bĂ©nignes. La sensibilitĂ© de l’élastographie Ă©tait de 82,02%, la spĂ©cificitĂ© de 83,94%, la prĂ©cision de 83,37%. Nous avons observĂ© 48 cas de lĂ©sions bĂ©nignes, identifiĂ©es par l’élastographie comme des lĂ©sions suspectes – 23/48 lĂ©sions avec de cellules HĂŒrthle, sans maladies vasculaires, 8/48 lĂ©sions prolifĂ©ratives potentiellement incertaines, 5/48 prolifĂ©ration folliculaire, 8/48 thyroĂŻdite myxomateuse / granulomateuse et 12/48 cas de maladie thyroĂŻdienne auto-immune. Nous avons Ă©galement notĂ© 24 rĂ©sultats faussement nĂ©gatifs: 19/24T microcarcinomes papillaires, 5/25 carcinomes folliculaires. Être mentionnĂ© que les microcarcinomes qui ont Ă©tĂ© observĂ©s dans les nodules, ont de diamĂštres supĂ©rieurs Ă  3,5 cm. Conclusions: Les prolifĂ©rations de cellules HĂŒrthle et les microcarcinomes papillaires sont les conditions pour faux diagnostic le plus frĂ©quent chez l’élastographie de la thyroĂŻde.Introduction: Real-time elastography is an imaging method that adds quality to the diagnosis of nodular thyroid lesions. Meta-analysis data suggest a good diagnostic performance with an overall specificity of 80% and sensitivity of 85%. The present study is a retrospective analysis of the most common causes of false negative and false positive results encountered in thyroid ultrasound. Material and methods: We analyzed 433 nodular lesions, operated and evaluated by classical thyroid ultrasound and elastography, using a linear probe on a Hitachi Preirus machine, Hitachi Inc., Japan: The results of the ultrasound were not communicated to the pathologist. A retrospective analysis of the results was performed. Results: We evaluated 433 thyroid nodules with an average volume of 2.14 ml (ranging from 0.78 ml to 10.45 ml). 134/433 cases were identified with thyroid cancer and 251/434 were identified as benign lesions. The sensitivity of the elastography was 82.02%, the specificity – 83.94%, the accuracy being 83.37%. We observed 48 cases of benign lesions, identified by elastography as suspicious lesions : 23/48 – lesions with HĂŒrthle cells, without vascular diseases, 8/48 – proliferative lesions potentially uncertain, 5/48 – follicular proliferation, 8/48 – myxomatous / granulomatous thyroiditis and 12/48 cases of autoimmune thyroid disease. We also noted 24 false negative results: 19 / 24 – papillary microcarcinomas, 5/25 – follicular carcinomas. Of note is that microcarcinomas that have been observed in nodules, had > 3.5 cm in diameter. Conclusions: Hurtle cell proliferations and papillary microcarcinomas are the most common misdiagnosed conditions in thyroid elastography

    Evaluation of medical decision errors during the transition period to telemedicine

    Get PDF
    The context of the Coronavirus pandemic has fundamentally changed the way we approach medical services. Beyond setting up new technological possibilities, it has propelled telemedicine to become a reality, bringing undeniable practical benefits. The questions that arise are both justified and worrying: can digitalization replace a direct interpersonal relationship that involves a physical examination, while preserving the quality of the medical act and the degree of patient satisfaction? Isn\u27t there a risk that the digitization of the medical record will cancel out the deep human character of classical medicine that has evolved since the time of Hippocrates? Should the implementation of telemedicine be the state-of-art of modern medicine, in accordance with the co-evolution of digital technology? It is hard to believe that once used in this period, telemedicine will be abandoned. However, telemedicine must be analyzed not only in the short term but also in the long term, in order to be able to evaluate both its usefulness and possible deficiencies

    Nerve compression due to benign tumors or ganglion cysts in the upper limb – case series

    Get PDF
    Tumor nerve compressions in the upper limb are relatively rare, usually involving ganglion cysts and benign tumors. We present a case series of five patients with peripheral nerve compression in the upper limb due to tumor or cystic masses- ulnar nerve compression in the Guyon’s tunnel due to a ganglion cyst, large median nerve schwannoma compressing anterior interosseous nerve and median nerve, voluminous lipoma compressing median nerve in the proximal forearm, superficial branch of radial nerve compression by a synovial cyst and elbow region lipoma compressing radial nerve. In the beginning, those benign lesions are asymptomatic but, as they continue to grow adjacent to a peripheral nerve clinical manifestations appear progressively as compressive neuropathies. After a preoperative imagistic analysis, tumor resection with careful dissection, in order to preserve the neurovascular structures, is the elective surgical procedure in order to obtain an optimal functional recovery
