The review emphasizes the actuality and importance of Marfan syndrome research worldwide. The hundred years old disease has been described mainly by its skeletal, ocular and cardiovascular manifestations, and constitutional type. The underlying gene mutations have been discovered in 1991. The surgical treatment of aortic root dilatation and dissection using Dacron tube reconstruction in emergency and prophylactic surgery has been published in 1955. Nowadays international foundations, database networks subjected Marfan syndrome as a rare disease with privileged research programs. The clinical Ghent nosology of pleiotropic criteria is accepted
world-wide (1996). The research programs are focused on international proposals.
Introduction: Crohn disease is an inflammatory bowel disease that involves any region of the alimentary tract from the mouth to the anus and it is transmural. Children with early onset are more likely to have colonic involvement. Infliximab constitutes today one of major therapeutic approaches at cases of Crohn’s disease.
Material and methods: We present the case of a 15-year-old female who was admitted in our department presenting pain of the large joints (exacerbated by movement), abdominal pain (epigastric and hypogastric), vomiting, diarrhea. In order to induce remission of the disease, we chose the step-up therapy (the only one accepted in Romania for children with Crohn disease). The initial response to immunosupressant therapy was moderate: no digestive symptoms were present, but extradigestive (articular) symptoms were still present and remission was not obtained (inflammation markers were still present and PCDAI was still above 15). We decided to try to induce remission with Infliximab.
Results: We obtained only temporary improvement of symptoms with “classical” therapy. We had a good response to Infliximab (remission was obtained), but treatment discontinuation without medical advise led to relapse after 9 months.
Conclusions: Infliximab was effective as therapy in Crohn’s disease with peripheral arthropathy, but too soon discontinuation of treatment due to patient’s non compliance determined relapse of the disease.
Introduction: The aim of this study is to investigate the anti-inflammatory action of daidzein on animal model a less studied isoflavone than genistein on this topic and to compare it’s anti-inflammatory activity with the one of soy total extract.
Material and method: Soybean seeds were grounded and a solvent formed of DMSO-ethanol-water in rapport 5-70-25 v/v/v was prepared. The extraction was made at room temperature using an ultrasonic bath (Falc LCD Series) for 30 minutes, 59 kHz. The solvent was evaporated with a rotary evaporator at 50 ºC. Daidzein was acquired from Extrasynthese (France).Animal studies were conducted on C57BL/6J female mice of 8 weeks. Edema was induced in both ears of each mouse by the topical application of 2 μg TPA dissolved in 20 μL of acetone to both the inner and outer ear surfaces. Thirty minutes after the application of TPA, the inner and outer surface of each ear was treated with 2 mg of soy total extract (group C) and 2 mg of daidzein (group D). Mice were killed after 24 h by cervical dislocation and ears were collected. Ears were weighed and histological analyze were made. For the histological analyze, tissue samples (skin) were fixed in 10% formalin solution and were embedded in paraffin and cut at 4 microns. Finally after deparaffinized the samples were stained with H&E (hematoxylin-eosin) and microscopically analyzed.
Results: The obtained results suggest that both of the samples used for the treatment are active agents against inflammation but with different empowering. Soy total extract is in charge of reducing the massive under epithelial inflammation with numerous granulocytes to a discrete under epithelial inflammatory infiltrate. Daidzein successfully reduced the massive under epithelial inflammation with numerous granulocytes to a discrete under epithelial edema.
Conclusion: Both daidzein and soy total extract present an anti-inflammatory action on animal model but daidzein is a better therapeutic choice since it has a stronger anti-inflammatory action.
Purpose: To compare the sensitivity of Short Tau Inversion Recovery magnetic resonance sequence with Fast Spin-Echo T2-weighted and Fluid-Attenuated Inversion Recovery magnetic resonance sequences in detection and evaluation of multiple sclerosis brain lesions.
Material and method: Fast Spin-Echo T2-weighted, Fluid-Attenuated Inversion Recovery and Short Tau Inversion Recovery sequences were performed in 7 patients with relapsing remitting multiple sclerosis. Qualitative assessment, regarding the number of lesions detected, conspicuity and lesion location was performed on all images in each sequence by two radiologists. Consensus was reached by agreement.
Results: When comparing Short Tau Inversion Recovery sequences with Fast Spin-Echo sequences, Short Tau Inversion Recovery showed 51 lesions more than Fast Spin-Echo sequences and increased the number of lesions detected by 38% in posterior fossa and by 27% in juxtacortical locations. When comparing Short Tau Inversion Recovery sequences with Fluid-Attenuated Inversion Recovery sequences, Short Tau Inversion Recovery sequences showed 72 lesions more than Fluid-Attenuated Inversion Recovery sequences and increased the number of lesion detected by 86% in posterior fossa and by 24% in periventricular areas.
Conclusions: By increasing the sensitivity Short Tau Inversion Recovery sequence might be suitable as an additional sequence in routine magnetic resonance brain examinations in patients with multiple sclerosis. Although Short Tau Inversion Recovery provides essential supplementary information to conventional imaging for the visualization brain lesions in multiple sclerosis, especially in posterior fossa, it is not a substitute for other sequences.
Introduction: Diastolic dysfunction is characterized by an increased resistance to filling with increased diastolic filling pressures. Aortic stenosis has become the most frequent type of valvular heart disease. Aortic stenosis increases diastolic filling pressures due left ventricular hypertrophy.
Material and methods: Our study is a retrospective one, and includes the IV. th Medical Clinic patients discharged in years 2009–2010. Thirty-four patients with severe aortic stenosis (group A), and 21 patients with moderate aortic stenosis (group B) underwent complete paraclinical evaluation.
Results: The mean age in the group A was 70 years, versus 67 years in group B. The left atrium anteroposterior diameter was 46 mm in grop A, and 43 mm in group B. In group A, the mean left ventricular thickness index was 0.51, versus 0.46 in group B. Severe diastolic dysfunction was present in 35% in group A , and in 19% in group B. The most frequent associated pathology was hypertension (35% in group A, 47% in group B).The most common complications were mitral insufficiency (31 patients in group A, 16 patients in group B), pulmonary hypertension (16 patients versus 9 patients).
Conclusions: The severe aortic stenosis was more frequent in advanced ages. The left atrium enlargement, the severe diastolic dysfunction, and a greater left ventricular wall thickness index were more common in patients with severe aortic stenosis. The most common associated risk factors in both groups were hypertension. The mitral regurgitation was more frequent in the severe aortic stenosis group.
Background: The dental pulp can be exposed by trauma or during cavity preparation and the decision between pulp capping and root canal therapy is a clinical issue.
The aim of this study was to evaluate the outcome of direct pulp capping procedures in permanent teeth.
Material and methods: Thirty-nine patients with pulp exposure were evaluated clinical and radiological after direct pulp capping procedure and followed for at least 24 months. The result was considered successful if the tooth tested was vital, without symptoms and no periapical radiolucencie.
Results: The success rate of direct pulp capping was 58.9%, associated more with mechanical exposure than with carious exposure (83.3% versus 48%, p < 0.05) and more with class I occlusal restorations (77.7%) than with proximal restorations (class II 44.4%, class III 41.6%, p < 0.05).
Conclusions: The success rate of direct pulp capping was 83.3% with mechanical exposure and 48% with carious exposure.
The aim of our study was to investigate the value of Doppler ultrasonography of the portal vein and hepatic artery in liver cirrhosis and to detect any relationship between the ultrasonographic changes and the severity of the portal hypertension and hepatic failure.
Methods: The study comprised 112 patients diagnosed with cirrhosis who had different degrees of esophageal varices, no ascites and who had been divided into groups according to Child-Pugh score. We evaluated the portal vein and hepatic artery velocities and we calculated the hepatic artery resistance and pulsatility index.
Results: Our data suggest that in patients with cirrhosis there is a significant correlation between the pulsatility index and the size of esophageal varices (p < 0.0001) and between the portal velocity and the size of esophageal varices (p < 0.0001). We found a significant inverse correlation between the portal velocity and the pulsatility index (r = -0.63) and a negative correlation between the portal velocity and the resistance index (r = -0.23).There was no correlation between the portal velocity and the peak systolic arterial flow (r = 0.017). There were no statistical differences of the studied portal vein and hepatic artery hemodinamics to different stages of liver
Conclusion: Portal vein and hepatic artery hemodinamics are unrelated to the degree of hepatic failure. In patients with cirrhosis the hepatic artery pulsatility index is correlated with the severity of the portal hypertension respectively with the degree of esophageal varices. Doppler ultrasound determination of these indices may contribute to a non-invasive evaluation of varices.
Background: In this work the applicability of capillary zone electrophoresis for the separation of quinolones from different generations has been studied.
Objective: Our aim was to develop a capillary electrophoretic method for the simultaneous separation of four quinolones and also to optimize the analytical conditions.
Material and methods: Capillary electrophoresis (CE) is a family of related techniques that use narrow-bore fused-silica capillaries to perform high efficiency separations of both small and large molecules. For this we chose four quinolones: a naftiridine derivate (nalidixic acid), a pyrido-pyrimidine derivate (pipemidic acid) and two second generation fluoroquinolones with different structures (ciprofloxacin, ofloxacin).
Results: A fast and reliable method has been developed, using a separation buffer composed of 40 mM natrium tetraborate and 5% methanol as organic modifier, with whom we achieved the separation of the studied quinolones in less than 10 minutes.
Conclusions: CE proved to be an efficient tool in the separation of quinolones from different generations.
Introduction: Increasing awareness, treatment and control rates of hypertensive patients is a worldwide problem especially in Central and East European countries.
The objective of the study was to determine the yearly changes in the achievement of treatment targets according to ESC 2003–2007 guidelines for the management of arterial hypertension in a preventive profiled ambulatory cardiology setting.
Patients and method: The study included 6591 hypertensive patients examined between 2002–2010 in the Procardia preventive ambulatory in Târgu Mureș, Romania. The sex distribution of the studied patients was 45.64% male average age 57.45 years, and 54.36% female average age 61.28 years. Patients received individually tailored self control education, lifestyle advice and drug treatment – the primary care providers were informed in detailed medical reports. We studied the yearly achievement of target blood pressure levels. We also analysed the frequency of investigations carried out for the global risk assessment screening for subclinical organ damage. We used “MedPrax” integrated patient data management system as an electronic health record. Statistical analysis was performed with the Open Office Calc programme.
Results: Target blood pressure values (under 140/90 mmHg in non diabetic patients and 130/80 in diabetic patients) were reached in 27.51%. The percentage of patients treated to target increased progressively from 15.25% to 36.29%.
Conclusions: The activity of the studied cardiology ambulatory setting provided a yearly increase in the level of blood pressure target achievement. Further improvement measures are needed to increase blood pressure control rates, with a specific attention to the diabetic patients.
Objectives: A number of biological, cytogenetic, molecular and clinical factors influence the evolution of patients with multiple myeloma. The study intends to evaluate prognostic value of beta-2 microglobulin in terms of survival of patients and response to chemotherapy and correlation with the main biological factors.
Material and method: The study analyses 44 patients diagnosed and treated between January 2006 and December 2010. Statistical analysis consisted of calculating correlation coefficient „r” (Pearson Bravais) and survival analysis using Kaplan-Meier curves.
Results: Beta-2 microglobulin was directly correlated with creatinine, hypercalcemia, percentage of bone marrow plasma cells, hyperproteinemia, monoclonal gradient, immunoglobulin G and inversely correlated with haemoglobin and low serum albumin. Median survival at patients having beta-2 microglobulin <3.5 mg/l was of 48 months, of 43 months at those having beta-2 microglobulin between 3.5 and 5.55 mg/l and 20 months at patients having beta-2 microglobulin >5.5 mg/l. Patients with beta-2 microglobulin <5.5 mg/l had complete remission in 52.38% of cases and 4.76% of patients did not respond to treatment as compared to patients having beta-2 microglobulin >5.5 mg/l, who had complete remission in 39.13% of cases while 30.43% showed no response. Median survival of patients with beta-2 microglobulin >5.5 mg/l was of 56 months at patients who
completely responded to chemotherapy and of 4 months at no responsive patients.
Conclusions: The high level of beta-2 microglobulin is a negative prognostic factor in the evolution of multiple myeloma patients, adversely influencing therapeutic response rates and reducing the survival of patients with multiple myeloma.
