Ossificação da sutura palatina mediana após o procedimento de expansão rápida da maxila: Estudo radiográfico

Objective: the current study aims at following up radiographically the evolution of the midpalatal suture during the expansion procedure since the opening of the suture until bone formation. Methods: the sample comprised 38 patients in the mixed dentition stage submitted to the rapid palatal expansion protocol of the Hospital for Rehabilitation of Craniofacial Anomalies. Results: it was observed an individual variation on the period of bone ossification of the midpalatal suture, which justifies the radiographic follow-up as determinant for the appliance removal. Due to long-term post-treatment stability, the expander should be removed after the new suture is completely formed. Conclusions: the findings show that it is necessary more than three months for the complete reorganization of the midpalatal suture during the passive phase of the rapid palatal expansion.

Comparative study of intramandibular glands of workers, queens and males of stingless bee Scaptotrigona postica Latreille (Hymenoptera: Meliponini)

The mandibles of bees contain two types of tegumental glands whose function is not clear, despite the hypotheses put forward by several researchers. Although these glands have been found in all the bee species studied so far, observations have been confined mostly to workers of eusocial species in the forager phase. The work reported here involved a study of the morphology of the glands of newly emerged, nurse and forager workers, virgin and fecundated queens, and newly emerged and sexually mature males of Scaptotrigona postica, seeking to identify changes that may be linked to the bees life phase. Our findings indicate that the two types of glands are present in the species but not in all life phases or individual classes. The glands consisting of class I cells, the epithelial glands are present only in forager workers and fecundated queens. Glands of type III cells were studied in detail, and gland size was estimated from histological sections. The degree of development of the glands varies according to individual classes and life phases, suggesting different functions during the individuals life and from one individual to another. © Koninklijke Brill NV, Leiden, 2012.

Mensuração das dimensões cardíacas pelo método VHS (Vertebral Heart Size) em cães

It is imortant to be able to evaluate the cardiact size . In 1995, was proposed by Buchanan and Bücheler a new way to measure the dimensions of the cardiac silhouette. This study aims to gather several studies of the cardiac dimensions by VHS method in the right lateral recumbency of of different breeds of dogs in a single work, facilitating the assess to information. Deep chest breeds have a smaller mean VHS value than the barrel chest breeds, showing that there is a variation of the VHS values acoording to the thoracic conformation of each breed, which indicates that there is a need to recognize the specific VHS values according to the breed standard to not to interpret the cardiac measurement in a wrong way through not compatible reference values for the animal. There is the individual variation that should be taken into accont at the time of measurement. The VHS is a helper method to a radiographic evaluation of the heart, and the ultrasonography remains the gold standard for the evaluation of the cardiac chambers and other changes of the heart

Intraoperative blood loss and blood transfusion requirements in patients undergoing orthognathic surgery

Procedures for the surgical correction of dentofacial deformities may produce important complications, whether due to the potential for vascular injury or to prolonged surgery, both of which may lead to severe blood loss. Fluid replacement with crystalloid, colloid, or even blood products may be required. The aim of this study was to assess blood loss and transfusion requirements in 45 patients (18 males and 27 females; mean age 29.29 years, range 16-52 years) undergoing orthognathic surgery, assigned to one of two groups according to procedure type-rapid maxillary expansion or double-jaw orthognathic surgery. Preoperative hemoglobin and hematocrit levels and intraoperative blood loss were measured. There was a substantial individual variation in pre- and postoperative hemoglobin values (10.3-17 and 8.8-15.4 g/dL, respectively; p < 0.05). Mean hematocrit values were 41.53 % preoperatively (range 31.3-50.0 %) and 36.56 % postoperatively (range 25-43.8 %) (p < 0.05). Mean blood loss was 274.60 mL (range 45-855 mL). Only two patients required blood transfusion. Although blood loss and transfusion requirements were minimal in the present study, surgical teams should monitor the duration of surgery and follow meticulous protocols to minimize the risks.
