The role of contrast-enhanced ultrasound in risk assessment of carotid atheroma

Background and objective: Contrast-enhanced ultrasound, used to assess atherosclerotic carotid plaques, improves visualization of vessel wall irregularities and depicts intraplaque neovascularization. This article illustrates the use of contrast-enhanced ultrasound in the risk assessment of carotid atherosclerotic lesions, especially in challenging plaques evaluation. Materials and methods: For 23 patients with difficult duplex ultrasound examination due to carotid tortuosity or calcifications we assessed plaque morphology (contour, echogenicity and stenosis degree) using contrast substance (Sonovue, Braco) with dedicated vascular low mechanical index CPC software. Conclusion: Contrast-enhanced ultrasound is a new, noninvasive, and safe procedure for imaging carotid atherosclerotic lesions. It is a valuable tool for evaluating the vulnerable plaque at risk for rupture and for the diagnostic of the development and severity of systemic atherosclerotic disease

MRI fusion biopsy vs transrectal ultrasound guided biopsy – A literature review

Introduction: Current diagnosis of prostate cancer is based on transrectal ultrasound guided random biopsies. These procedures alongside with the discovery of PSA lead to a tremendous improvement of prostate cancer diagnosis rate in the last decades. Random ultrasound guided biopsy has its minuses and several attempts were made to improve the detection rate of the disease. MRI-US fusion targeted biopsies is one of them. Aim: This paper is a literature review of several important European studies and tries to draw a conclusion for the usefulness of MRI-US image fusion prostate biopsy in improving prostate cancer detection Material and methods: We have analyzed 5 papers published since 2013 which compare random ultrasound biopsies with MRI-US fusion. The analyzed parameters were clinical significant cancer detected as described by the study and any cancer detected Results: All 5 papers show superiority in cancer detection rates for both clinically significant and any cancer. Conclusions: MRI-US is a useful tool for improving detection rate of clinically significant prostate cancer. INTRODUCTION in general Prostate cancer is a serious public health matter, being the first cancer in men in terms of incidence and the second cause of cancer death in the U.S. in the Cancer, following year cardiovascular diseases as the leading cause of mortality. Prostate cancer, in particular is becoming more and more important due population aging. [1] is taught to surpass While throughout the history prostate cancer was poorly understood, with few cases recorded due to the low life expectancy, during the XXth century groundbreaking understanding, diagnosing and treating the disease. discoveries were made in Early diagnosis methods included open transperineal biopsies, blind transperineal needle biopsy and finger guided transrectal biopsy. First attempts to use transrectal ultrasound for prostate imaging were made by Takahasi and Ouchi in 1963 but they in 1968 obtained poor performed first clinical useful TRUS. In 1989 Hodge and al. started the modern era of standard sextant [2].

Using direct anticoagulants (DOACs) in cancer and other high-risk populations

The major practical advantage of the direct oral anticoagulants (DOACs), comprising the thrombin inhibitor dabigatran and the factor Xa inhibitors apixaban, edoxaban, and rivaroxaban, over vitamin K antagonists is their fixed dosing without the need for laboratory monitoring. With the recent, rapid introduction of the DOACs for the treatment of acute venous thromboembolism (VTE), clinicians are now faced with various questions regarding the efficacy and safety of these compounds overall and in specific high-risk populations. The collective evidence from 6 large clinical trials involving 27,000 patients has demonstrated that DOACs are as effective as vitamin K antagonists (VKA) in preventing recurrent VTE while being associated with a significantly lower risk of major bleeding. These findings are consistent in subgroups of patients with pulmonary embolism, the elderly, and those patients with a high body weight or moderate renal insufficiency, making these agents suitable for a broad spectrum of patients with VTE. DOACs are also an attractive treatment option in patients with VTE and concomitant cancer, thrombotic antiphospholipid syndrome, or heparin-induced thrombocytopenia, but the currently available clinical data is insufficient to make evidence-based recommendations on the use of DOACs in these settings. Several studies evaluating the efficacy and the safety of DOACs in these high-risk populations are underway.

The consequences of Chernobyl accident Ion Chiosila1

These days marks 30 years since the Chernobyl nuclear accident, followed by massive radioactive contamination of the environment and human in Belarus, Ukraine and Russia, and resulted in many deaths among people who intervened to decrease the effects of the nuclear disaster. The 26 April 1986 nuclear accident contaminated all European countries, but at a much lower level, without highlighted consequences on human health. In special laboratories, the main radionuclides (I-131, Cs-137, Cs-134 and Sr-90) were also analyzed in Romania from environmental samples, food, even human subjects. These radionuclides caused the population to receive a low dose of about 1 mSv in 1986 that is half of the dose of the natural background radiation (2.4 mSv per year). As in all European countries (excluding Ukraine, Belarus and Russia) this dose of about 1 mSv fell rapidly by 1990, reaching levels close to ones before the accident at the nuclear tests.

Gut microbiota – new insight in colorectal cancer pathogenesis

Gut microbiota is a superorganism involved in homeostasis and in pathogenesis. Microbiota composition is influenced by several factors such as: type of birth (cesarean or natural), role of age, role of diet. Pathological consequences of certain type of diet (especially western type of diet) may, in fact, be mediated by gut microbiota alteration. Also few studies have investigated the issue of gut microbiota composition in patients suffering of colorectal cancer, several reports notice relevant differences. Certain pathogenic bacteria in gut microbiota have been extensively studied in relation to their role in colorectal cancer. Thus, Fusobacterium nucleatum, which is abundant in colorectal cancer patient’s colon, may initiate the progression from adenoma to adenocarcinoma. A suggested pattern of oncogenesis in colorectal cancer may be represented by this: dysbiosis-inflammation-oncogenesis. A metanalysis that has been published in 2006 concluded a protective role of probiotics in colorectal cancer and in colonic adenoma.

Heart failure with preserved ejection fraction: A review

Heart failure is the final stage of evolution of a large number of cardiovascular diseases and represents a health problem worldwide, due to increased prevalence of cardiovascular diseases. The patients with heart failure with preserved ejection fraction (HFpEF) represent about a half of the patients with heart failure and the prevalence of HFpEF is on the rise. HFpEF is mainly a disease of the elderly patients, who have numerous cardiovascular diseases – hypertension, myocardial ischaemia, atrial fibrillation, valvular disease, and also non-cardiovascular comorbidities, such as obesity, diabetes mellitus, chronic kidney disease, chronic obstructive pulmonary disease, and obstructive sleep apnoea. HFpEF is more prevalent in women than in men, but women have a better prognosis than men. The pathophysiological changes that appear in HFpEF are: ventricular stiffening, cardiomyocite hypertrophy and hypercontractility, myocardial fibrosis and inflammation, which lead to abnormal diastolic function with delayed relaxation and inappropriate filling, in the presence of a normal systolic function of the left ventricle. The diagnosis of HFpEF is based on clinical, echocardiographic and biological criteria. In contrast to HFrEF, there is no effective treatment for HFpEF. The treatment of HFpEF includes diuretics for clinical improvement and treatment of comorbidities. The prognosis of patients with HFpEF is similar with those with HFrEF. Currently, the main objectives of the treatment in patients with HFpEF are to improve clinical status and decrease hospitalizations. Further studies are needed to establish an effective treatment to increase survival in these patients. Therefore, HFpEF continues to be a challenge for clinicians regarding the optimal therapy..

Complications of systemic lupus erythematosus: A review

Systemic lupus erythematosus (SLE) is a complex autoimmune condition, which often evolves with severe complications. In SLE, autoantibodies appear, with systemic inflammation and multiple tissue destructions. SLE is the most common form of lupus and is considered more severe than other forms. SLE can affect many parts of the body, including the kidneys, heart, lungs, brain, blood, and skin. Symptoms vary among patients. SLE can follow an unpredictable pattern of remissions (symptoms improve) and flares (symptoms worsen). Renal involvement is one of the most severe complications in SLE patients. The process of depositing the immune complexes in the kidneys could lead to the appearance of lupus nephritis. If the treatment is early and treat-to-target, it can change the course of the renal disease.

History of medicine on the border between philosophy and science

Physicians have represented a long time the main transmitters of knowledge as they were real scholars. If Renaissance promoted the study of the human body anatomy and physiology, the next step made by practitioners of medicine was to spread the enlightenment. That meant the shift of the very purpose of their profession: from passive opposition to ailments towards an active involvement into the lives of the impoverished. In order to change the odds in the battle against diseases, physicians had the great burden to enlarge the cultural horizons of those whose health was in their hands. Therefore, one way of imparting knowledge was by publishing and spreading their attainments to the general public in a comprehensible way. Once people gained awareness of the dangers entailed by bad hygiene, the physicians’ role in society switched towards more cultural realms. At the beginning of the 20th century health care professionals achieved the next step in the becoming of medicine: setting up a new science to link humanities with pure science. In Romania, the main promoters of this new border science were Victor Gomoiu and Valeriu Bologa and they co-opted other intellectuals.

Ethical limits between aesthetic and cosmetic dentistry

Esthetics is the “new trend” in dental medicine as a natural consequence of the development of modern society, with implications in practice and training. Like any rule in art, but also within the medical field, esthetics must be known and addressed in relation to other medical or non-medical principles (dental cosmetic), respect the ethics rules. Aim. Literature study designed to focus on the current problems that modern dentistry is facing, in relation to esthetic requirements. The literature search strategy in electronic databases: EBSCO Data Base, Dentistry & Oral Sciences Source, Pub Med indexed articles, used Boolean Operators. As a conclusion, the dentist must be familiar with the differences between esthetic and dental cosmetic, must minimize the subjective component of the examination, identify the reasons of presentation, guide the patient in choosing the optimal treatment, including obtaining the desired esthetic results, within the ethical boundaries of the noble medical profession.
