ABSTRACT

Takayasu arteritis (TA) is a rare, large vessel vasculitis that affects aorta, its major branches, and occasionally pulmonary arteries. Patients with TA can present with constitutional features and/or various symptoms and signs caused by morphological changes in the blood vessels affected by the inflammatory process. Corticosteroids (CS) and immunosuppressives (IS) are the first line treatment for active TA. Open surgery remains a treatment of choice for TA patients with moderate-to-severe aortic regurgitation (AR) and ascending aortic aneurysm (AAA). We present a 26-year-old female diagnosed with an advanced stage of TA, initially presented as congestive heart failure. Due to a progressive course of the disease (AR 3+, AAA 5.5 cm), surgery of the Aortic valve and root (Bentall procedure), with total arch reconstruction and replacement of supra-aortic branches was performed. The patient has had an uneventful recovery during the postoperative course with no complications at one year follow-up. Normal left ventricle (LV) diameter, LV ejection fraction 67%, and a trace of AR were seen on the last echocardiography.

ABSTRACT

The best treatment for end stage renal disease (ESRD) patients is kidney transplantation, but the renal transplant recipients still have a higher incidence of cardiovascular events compared with general population. Cardiovascular risk factors were imposed long before ESRD, as the majority of patients starting dialysis or kidney transplantation already have signs of advanced atherosclerosis. Artery calcification is an organized, regulated process similar to bone formation. Coronary artery calcification (CAC) is found frequently in advanced atherosclerotic lesions and could be a useful marker of them. We evaluated the prevalence of CAC in 49 stable renal transplant recipients and in 48 age- and gender-matched patients with chronic kidney disease (CKD) in stages 2-5 not requiring dialysis to assess risk factors associated with CAC. Computed tomography was used for CAC detection and quantification (CAC score). The prevalence of CAC was 43.8% in transplant recipients and 16.7% in CKD patients (p < 0.001). Transplant recipients with CAC were significantly older and had longer duration of CKD and/or dialysis than recipients without CAC. In contrast, the serum levels of fetuin A (an inhibitor of vascular calcification) and albumin were significantly lower in CKD patients with CAC than those without CAC. During the observation period (30 months), 30 patients, including 23 CKD patients, began dialysis, and 4 transplant recipients and 2 CKD patients died. Independent predictors of mortality were age, serum amyloid A and the CAC score. In conclusion, the examination and prevention of risk factors associated with atherosclerosis should be started at the beginning of renal failure.

ABSTRACT

INTRODUCTION: Intramural haematoma (IMH) and penetrating aortic ulcers (PAU) are the frequent cause of acute aortic syndrome that is disclosed with a rising frequency due to the development of new diagnostic methods. Different symptoms contribute to clinical misdiagnosis, while changeable locations and unpersuasive diameter can lead the radiologists to underestimate such changes. The outcome of PAU and IMH differs, and for the time being there are no data on prognostic factors. The diversity of symptoms and disease course is presented in four cases with different manifestations, treatment and outcome. OUTLINE OF CASES: Two patients with IMH were treated conservatively due to the process extensiveness and its morphology. One patient had a complete restitution, while the other had progression of the disease. Other two patients with PAU were treated by surgery (stent graft implantation) according to the morphology and diameter of the aorta. CONCLUSION: IMH and PAU should be suspected in patients with unclear clinical presentation (back and abdominal pains). Although outcome and complications of these diseases are well known, their incidence has not been fully studied. Endovascular treatment is less invasive and followed by a potentially lower rate of complications. However, usage of this method is justifiable only in patients with associated complications.

ABSTRACT

Pulmonary diseases are well documented and diverse in many patients with HIV in clinical stages 3 and 4. It is not unusual that these patients, most of whom do not know that they are already HIV-infected, are first examined and hospitalised by respiratory medicine specialists. While HIV-infection is relatively simple to diagnose if accompanied by advanced clinical manifestations and is regularly checked in patients with increased risk, this is not the case in low-risk patients, particularly in countries with low-level HIV epidemic and therefore low index of suspicion. Regular examination involves a series of tests, often including bronchoscopy with transbronchal lung biopsy in order to identify an interstitial lung disease and/or progressive dyspnoea. It is not uncommon that patients provide false or incomplete information about their lifestyle, which can mislead the clinician. At this point, HIV-infection is usually not suspected and healthcare workers may not strictly be following the safety principles which are otherwise applied when HIV-infection is known or suspect, although universal precautions are routine practice. At this point, the risk of exposure is the highest and HIV-transmission to healthcare workers is the most likely to occur. The cases presented here indicate that patients with progressive dyspnoea, which is typical of interstitial lung diseases, should undergo HIV-testing as a part of good clinical practice, even in a country with low-level HIV epidemic.

ABSTRACT

The most frequent benign gallbladder polyps are cholesterol polyps. Next in frequency were adenomas, which may have malignant potential. The aim of this study was to assess the possibility of ultrasonography in the diagnosis and differential diagnosis of cholesterol polyps compared to adenomas. Patients were examined during the period from October 2006. to December 2008. In Department of Ultrasound, Clinic for Gastroenterology and Hepatology, Belgrade. The group of 54 patients analyzed consisted of 30 women (56%) and 24 men (44%). Most (59%) had solitary polyps. In 92.6% of patients the size of polyps was below 10 mm. 74% of respondents were over 50 years. Ultrasonography is the method of choice and gold standard in diagnosis of gallbladder polyps. Based on echoic properties cholesterol polyps can not be distinguished from adenomas. Malignant alteration of polyps also could not be detected. Appropriate ultrasonographic characteristics such as size of polyps, appearance of a broad base that sits on the wall, concomitant lithiasis findings and patient age may be indicative for malignancy.

ABSTRACT

Cardiac involvement by non-Hodgkin's lymphoma is not uncommon, however rarely diagnosed during life due to nonspecific clinical presentation. We report a case of secondary cardiac lymphoma in patient who presented with new-onset atrial fibrillation. Cardiac lymphoma was in a form of bulky right atrial mass, infiltrating the atrial septum and cavo-atrial junction with concomitant mild pericardial effusion. In the present case, we illustrate complementary role of transthoracic, transesophageal echocardiography and multislice CT scan with three-dimensional reconstruction, in detection and evaluation of secondary cardiac tumor. Usefulness of echocardiography to follow up the effects of chemotherapy is also shown.

ABSTRACT

The life of a star is dominantly determined by the physical processes in the stellar interior. Unfortunately, we still have a poor understanding of how the stellar gas mixes near the stellar core, preventing precise predictions of stellar evolution. The unknown nature of the mixing processes as well as the extent of the central mixed region is particularly problematic for massive stars. Oscillations in stars with masses a few times that of the Sun offer a unique opportunity to disentangle the nature of various mixing processes, through the distinct signature they leave on period spacings in the gravity mode spectrum. Here we report the detection of numerous gravity modes in a young star with a mass of about seven solar masses. The mean period spacing allows us to estimate the extent of the convective core, and the clear periodic deviation from the mean constrains the location of the chemical transition zone to be at about 10 per cent of the radius and rules out a clear-cut profile.

ABSTRACT

Inhalation of asbestos fibres leads to asbestosis of the pleura and the lung, with possible progression to lung cancer and malignant pleural or peritoneal mesothelioma. Asbestosis remains difficult to diagnose, especially in its early stages. The most important role in its diagnosis is that of chest radiographs. The aim of this cross-sectional study was to address interobserver variations in interpreting chest radiographs in asbestos workers, which remain to be an issue, despite improvements in the International Labour Office (ILO) classification system. In our ten-year study, we investigated 318 workers occupationally exposed to asbestos, and in 210 workers with diagnosed asbestos-related changes we compared interpretations of chest radiographs according to ILO by two independent radiologists. The apparent degree of interobserver variation in classifying lung fibrosis was 26.66% for the diameter of changes and 42.2% for the profusion of the changes. In cases with diffuse pleural thickening, the interobserver variation using ILO procedures was 34.93%. This investigation raises the issue of standardisation and objectivity of interpretation of asbestosis according to the ILO classification system. This study has revealed a significant disagreement in the estimated degree of pleural and parenchymal asbestos pulmonary disease. This is why we believe high-resolution computed tomography (HRCT) should also be used as a part of international classification.

ABSTRACT

OBJECTIVE: Symptomatic, anatomic and urodynamic results of a composite transobturatory tension-free sling with an absorbable middle part, in patients with stress urinary incontinence (SUI), were studied. METHODS: A prospective study in 40 women with SUI was performed. Symptoms, urodynamics and anatomical improvements were evaluated separately. Surgery was performed with the transobturatory approach. RESULTS: All patients had both clinically and urodynamically confirmed SUI. Clinical outcome was favorable in 36/40 (90%) patients, after 1 year. Operation improved the position of the bladder neck (2.8 cm and 1.4 cm below the pubic bone, respectively) and significantly decreased mobility of the bladder neck during abdominal straining (3.3 cm and 1.7 cm, respectively). Both symptoms and quality of life were significantly improved 1 month after the surgery. Postoperative maximum flow was lower than the preoperative one but with borderline significance (25.8 and 23.7 mL/s; P = 0.05). Pressure flow study showed unobstructed voiding both preoperatively and postoperatively. Detrusor pressure at the maximum flow was increased (20, 4 and 22, 8 cmH(2)O, respectively) but not significantly. CONCLUSION: Our results confirmed a high objective cure rate, improvement of symptoms and quality of life, and at the same time, corrected position of the bladder neck and unobstructed voiding.
