Introduction

In this case report we present the aesthetical correction of crowded anterior teeth in a patient who has refused the orthodontic treatment. We also discuss how this correction can be resolved from the point of view of dental prosthetic and what measurements can be helpful in order to collect the data used to restore a satisfying smile on the patient’s face using dental ceramic restoration. Case presentation: A 32-year-old patient complained about his crowded incisors. We examined the incisal curvature, the proportion between the height and the width of the teeth, and the relation between the widths of the teeth and the golden proportion. The results of the measurements were compared to the characteristic values of the ideal denture. After the examination of the dental plaster cast, calculating the difference between the existing space and the necessary space, we were able to calculate the lack of space, which caused the crowded teeth. Conclusion: Along the prosthetic planning, these measurements may serve as a guideline to the dentist as an objective basis for the formation of an aesthetic denture and smile.

Abstract

Background: High-dose chemotherapy and autologous stem cell transplantation have become a standard curative treatment in various hematologic malignancies. Many factors can affect the success of mobilization and hematopoietic stem cell harvesting.

Aim: The aim of this study was to analyze factors that lead to mobilization failure.

Material and Methods: We conducted a retrospective study on 19 patients with failure of stem cell harvesting. All patients were administered high doses of GCS-F (filgrastim, 15 μg/kg/day) and 0.24 mg/kg of plerixafor on day +5 or +10 of harvesting.

Results: The median age of the study population was 51 years (range 35–67) and 52.6% (n = 10) were males. The study group included 4 (21%) subjects with multiple myeloma, 6 (31.5%) with Hodgkin lymphoma, 8 cases (42.1%) with non-Hodgkin lymphoma and 1 patient with chronic lymphocytic leukemia. Each patient received 2.78 (range 1–5) lines of chemotherapy, administered in 11.57 (range 2 to over 20) cycles of treatment.

Conclusion: In hematologic malignancies it is very important to collect stem cells in time, in order to reduce mobilization failure. As we have shown in our studied cases, multiple lines of polychemotherapy with or without radiotherapy lead to mobilization failure.

Abstract

Introduction: Pulmonary arterial hypertension (PAH) is a complex disease with poor prognosis. Serum uric acid has been proposed as a potentially non-invasive and objective parameter for prognosis and response to therapy.

Objectives: To investigate the potent relationship between serum uric acid levels and functional and echocardiographic parameters in children with PAH.

Methods: Serum uric acid levels were measured in 34 children with PAH and were correlated with the functional class, 6-minute walk test, and echocardiographic parameters at baseline and at 12 months follow-up.

Results: In pediatric PAH patients serum uric acid levels were higher compared with the control subjects (p = 0.001). In the high uric acid group serum uric acid levels were correlated with 6-minute walk test (p = 0.008), and with several echocardiographic parameters, such as pulmonary vascular resistance (p = 0.04), fractional area change (p = 0.05), left ventricle eccentricity index (p = 0.04), right atrial area (p = 0.03), right ventricle myocardial index (p = 0.01), and pericardial effusion (p = 0.001), markers of right ventricular overload and dysfunction.

Conclusions: Serum uric acid levels are easy to collect and measure, and correlate with both functional and echocardiographic parameters that reflect right ventricular dysfunction.

Abstract

Background: The need for the whitening effects of toothpastes became primary for most users. Changes in the surface roughness of restoration materials after tooth brushing are inevitable, and the abrasion is known to increase the possibility of dental plaque accumulation. Aim of the study: To evaluate in vitro surface roughness changes of different dental restorative materials after tooth brushing simulation. Material and methods: Fifty specimens of two composite materials (Evicrol, Super-Cor), two glass ionomer materials (Glassfill, Kavitan Cem) and a silicate cement (Fritex) were prepared according to the manufacturer’s instructions. Each group of specimens was divided in three subgroups for tooth brushing simulation: using two different types of toothpaste and without toothpaste. Before and after 153 hours of tooth brushing simulation with a custom-made device, the surface roughness was measured with a surface roughness tester. Statistical analysis was performed after collecting the data. Results: All materials exhibited changes in surface roughness after the use of both toothpastes. The self-curing composite showed the less change and glass ionomer materials showed the greatest changes in surface roughness. Conclusions: The surface changes of dental materials depended on their composition and the cleaning procedure. Although self-curing composite was the most resistant to surface changes, its surface roughness values were high. Light-curing composite presented the lowest surface roughness values, even after brushing with toothpastes. The “medium” labeled toothbrush caused significant changes without toothpaste on the surface of light-curing composite, glass ionomer and silicate cement materials.
