Aparelho de Herbst associado a aparelhos fixos: descrição de técnica

This paper aims at describeconstruction and installation sequences of a new design of appliance that allows continuously protraction of the mandible, using the telescopic mechanism of the Herbst appliance. This appliance has the advantage to be easily assembled by the orthodontist, without the necessity of molding and the assistance of a specialized laboratory, as well as the constant permanence in the mouth of the patient for being fixed.

Tratamento ortodôntico lingual individualizado com o sistema Incognito

Introduction: The orthodontic treatment using lingual brackets has been desired by adult patients for esthetic factors. In this paper it is described the clinical steps of an orthodontic treatment using Incognito™ system, individualized lingual brackets and archwires designed by CAD/CAM technology. Methods: The presented case describes the treatment of a patient with mesofacial growth pattern,Class I malocclusion, with mandibular crowding and diastema between the upper central incisors, treated using 100% individualized lingual brackets. Results: After treatment, the molar relation of Class I was kept, the spaces between upper central incisors were closed and mandibular crowding corrected. Conclusion: This case report demonstrated the efficiency of the new method for lingual orthodontic treatment.

Factors associated with red blood cell transfusions in very-low-birth-weight preterm infants in Brazilian neonatal units

Preterm infants in neonatal intensive care units frequently receive red blood cells (RBC) transfusions due to the anemia of prematurity. A number of variables related to gestational age, severity of illness and transfusion practices adopted in the neonatal unit where the neonate was born may contribute to the prescription of RBC transfusions. This study aimed to analyse the frequency and factors associated with RBC transfusions in very-low-birth-weight preterm infants. A prospective cohort of 4283 preterm infants (gestational age: 29.9 ± 2.9 weeks; birth weight: 1084 ± 275 g) carried out at 16 university hospitals in Brazil between January 2009 and December 2011 was analysed. Factors associated with RBC transfusions were evaluated using univariate and multiple logistic regression analysis. A total of 2208 (51.6%) infants received RBC transfusions (variation per neonatal unit: 34.1% to 66.4%). RBC transfusions were significantly associated with gestational age (OR: -1.098; 95%CI: -1.12 to -1.04), SNAPPE II score (1.01; 1.00-1.02), apnea (1.69; 1.34-2.14), pulmonary hemorrhage (2.65; 1.74-4.031), need for oxygen at 28 days of life (1.56; 1.17-2.08), clinical sepsis (3.22; 2.55-4.05), necrotising enterocolitis (3.80; 2.26-6.41), grades III/IV intraventricular hemorrhage (1.64; 1.05-2.58), mechanical ventilation (2.27; 1.74-2.97), use of umbilical catheter (1.86; 1.35-2.57), parenteral nutrition (2.06; 1.27-3.33), >60 days of hospitalization (5.29; 4.02-6.95) and the neonatal unit where the neonate was born. The frequency of RBC transfusions varied among neonatal intensive care units. Even after adjusting for adverse health conditions and therapeutic interventions, the neonatal unit continued to influence transfusion practices in very-low birth-weight infants.

Characterization of the hemoglobins and globins of Synbranchus marmoratus Bloch, 1795 (Pisces, Synbranchidae)

1. 1. Total hemolysates of Synbranchus marmoratus Bloch, 1795, captured in Vitoriana, district of Botucatu, State of São Paulo, Brazil, were submitted to agar-starch gel electrophoresis on glass slides using 42 mM-Tris 1.7 mM EDTA-6.1 mM borate buffer, pH 8.8, for the gel and 10 mM borate-1.7 mM NaOH buffer, pH 8.6, for the cuvette. 2. 2. Three distinct hemoglobin bands were detected, with Hb I being of the cathodic type. 3. 3. Cellulose acetate electrophoresis in 800 mM Tris-2.1 mM EDTA buffer, pH 8.9, containing 6 M urea and 2.25 mM β-mercaptoethanol indicated the presence of four globin chains denoted α 1, α 2, β and γ. 4. 4. It is suggested that the probable tetrameric constitution of the hemoglobin of Synbranchus marmoratus Bloch, 1795 is Hb I (α 2 2γ 2), Hb II (α 2 1γ 2) and Hb III (α 2 1β 2). © 1986.
