Heart failure (HF) and renal dysfunction are frequent associated in the same patient. The purpose of our study was to assess the prevalence of renal dysfunction and the clinical status in admitted patients for decompensated HF. Material and Methods. 397 patients succesively hospitalized for decompensated HF, NYHA III or IV functional class, with left ventricular ejection fraction (LVEF) � 45% were included in the study. Renal dysfunction was defined by glomerular filtration rate (GFR) [ 60 mL/min/1.73 m 2. The mean GFR in patients with HF was 63.89 � 21.5 mL/min/1.73 m2 .The prevalence of renal dysfunction was 49.6%. Patients with GFR [ 60 mL/min/1.73m2, compared with those with preserved renal function were significantly more frequent older (75.37 � 6.84 vs. 71.33 � 8.08 years; p [0.001), females (53,8% vs. 43.5%; p = 0.04), had a significantly higher prevalence of diabetes mellitus (50.2% vs. 28.5%; p [0.001), atrial fibrillation (53.8% vs 46.2%, p = 0.04) and anemia (47.7% vs. 29.5% ; p [0.001). Also, patients with renal dysfunction had more severe HF than those without renal dysfunction (NYHA class IV: 65% vs 45%, p [0.001, clinical congestion: 78.2% vs 68%, p = 0.02, LVEF [35%: 47.21% vs � 35%, p [0.001). Renal dysfunction can be considered an additional marker of severe cardiac dysfunction along with NYHA IV class and low LVEF. The presence of both renal dysfunction and anemia could represent prognostic markers in HF patients with reduced LVEF.

The aim of our study was to evaluate fracture resistance of the PMMA complete dentures and to make a comparison between the classic acrylic maxillary complete dentures and the metal-reinforced ones, in terms of fracture resistance during function and to compare the fracture pattern of the two groups of complete dentures. We used maxillary complete dentures made of heat-processed acrylate, 5 exclusively and 5 in which a metal-cast net in the form of a mesh was inserted after being casted, worn by patients for a period of 5 years. A bilateral progressive force was applied to the PM2-M1 area until the samples failed, recording the force value at which the first change occurred. A Universal Loading Machine was used. The results were analyzed using the ANOVA method. For the classic acrylic complete dentures group, the minimum fracture force value was 1060 N, the maximum fracture force value being 2443 N. For the reinforced complete dentures group, the minimum fracture force value was 3320 N, the maximum value being 3760 N. Statistical analysis of data using the ANOVA shows that the results are statistically relevant, with a p value of 0.000137 (p[0,05). All the dentures from the classic acrylic complete dentures group fractured presenting two or more fracture lines, most of them involving also fractures on the acrylic teeth and breaking into multiple pieces, while all the dentures from the reinforced complete dentures group fractured presenting one or two fracture lines, most of them without detachable fragments and involving also fractures on the acrylic teeth.

The aim of this study was to evaluate pain intensity and wound healing of the post-extraction sites after the use of Platelet-Rich Fibrin (PRF). 240 patients which needed difficult or multiple extractions were included in the study. The extractions were realized under local anesthesia, with piezotome and pliers. The patients were divided in two groups, the first group of 120 patients which benefited the application of PRF in the post-extraction alveoli, and the second group of 120 patients represented the control group (without application of PRF). A questionnaire was realized after a VAS analog scale and was used to quantify the post-intervention pain intensity in the postoperative four days. The assessment of the post-extraction sites healing period was performed clinically. According to the obtained results, the healing period of the post-extraction sites was shorter in the patients of first group (PRF), compared to the sites of control group patients. No postextractional healing complications occurred in the patients of first group/PRF. The study demonstrated the benefits of PRF insertion in post-intervention healing.

Introductions. The vicious habit of sucking the thumb is an etiological factor of Angle Class II/1 malocclusion. Case presentation. In the clinical case that we intend to present, the main goal of the treatment was to recover the occlusion and the functions of the dento-maxillary complex. The treatment relied on the use of a fixed appliance. The sagittal inocclusion was thus reduced and the parameters of occlusion were brought to normality. Conclusions. We consider that the period of orthodontic treatment was reduced because the climax of the bones growth took place at the same time with the eruption of the 12-year-old molars.
