Stress materno e hospitalização infantil pré-cirúrgica

O objetivo deste estudo foi a valiar o nível de stress de mães acompanhantes de crianças hospitalizadas para realização de procedimentos cirúrgicos eletivos, relacionando-o com variáveis demográficas da criança e experiência prévia no contexto. Participaram 54 mães acompanhantes de crianças hospitalizadas para realização de cirurgia eletiva. Utilizaram-se como instrumentos o Inventário de Sintomas de Stress para Adultos de Lipp e, para levantamento das variáveis da criança, um questionário elaborado para o estudo. Os resultados apontaram que 82% da amostra apresentavam stress, prevalencendo a fase de resistência e sintomas psicológicos. Observou-se relação estatisticamente significativa entre a presença de stress materno e o fato de o filho não ter experiência anterior com cirurgia (p=0,052). Por outro lado, não foram observadas diferenças estatisticamente significativas entre a presença de stress materno e a idade e gênero da criança. Conclui-se que o impacto dos procedimentos cirúrgicos acomete a criança e a família, o que deve ser levado em consideração a fim de que sejam propostas intervenções para a preparação pré-operatória.

Retroperitoneoscopic renal biopsy in children

OBJECTIVE: We present our experience in a series of 17 consecutive pediatric patients submitted to retroperitoneal laparoscopic renal biopsy. MATERIALS and METHODS: Retroperitoneal laparoscopic renal biopsy (LRB) was performed in 5 boys and 12 girls. Mean age was 8.1 years and age range from 2 to 12. Two or three trocars were used to expose the inferior pole of the kidney, remove enough cortical parenchymal specimen and fulgurate the biopsy site. Assessment included surgical time, estimated blood loss, hospitalization period, analgesia requirements, complications and number of glomeruli present in the specimen. RESULTS: LRB was successfully performed in all 15 patients (88%). In two cases, LRB was not possible to be performed. One patient was converted to a transperitoneal laparoscopy due to tear in the peritoneum. The other patient had had previous abdominal surgery and, during retroperitoneal balloon dilation, the peritoneum was opened and the open biopsy was performed. A third patient had postoperatively a perirenal hematoma, which was solved spontaneously. Complication rate was 17.6% (3/17 cases). Mean operative time was 65 minutes, while mean estimated blood loss was 52 mL, mean hospital stay was 2.2 days and mean analgesic requirement was 100 mg of tramadol. The mean number of glomeruli present in the specimen was 60. CONCLUSION: Retroperitoneal laparoscopic renal biopsy in children is a simple, safe. Bleeding is still the most common complication. However, direct vision usually allows a safe control of this drawback. In our institution, laparoscopic approach is the chosen procedure in pediatric patients older than one - year - old.

Clinically, bioglass was able to maintain bone architecture of the alveolar bone and repaired satisfactory. Biopsy was performed on the histologic samples and showed bone formation in intimate contact to the particles of the biomaterial.

Comparative study of 2 software programs for predicting profile changes in Class III patients having double-jaw orthognathic surgery

Introduction: Computer software can be used to predict orthognathic surgery outcomes. The aim of this study was to subjectively compare the soft-tissue surgical simulations of 2 software programs. Methods: Standard profile pictures were taken of 10 patients with a Class III malocclusion and a concave facial profile who were scheduled for double-jaw orthognathic surgery. The patients had horizontal maxillary deficiency or horizontal mandibular excess. Two software programs (Dentofacial Planner Plus [Dentofacial Software, Toronto, Ontario, Canada] and Dolphin Imaging [version 9.0, Dolphin Imaging Software, Canoga Park, Calif]) were used to predict the postsurgical profiles. The predictive images were compared with the actual final photographs. One hundred one orthodontists, oral-maxillofacial surgeons, and general dentists evaluated the images and were asked whether they would use either software program to plan treatment for, or to educate, their patients. Results: Statistical analyses showed differences between the groups when each point was judged. Dolphin Imaging software had better prediction of nasal tip, chin, and submandibular area. Dentofacial Planner Plus software was better in predicting nasolabial angle, and upper and lower lips. The total profile comparison showed no statistical difference between the softwares. Conclusions: The 2 types of software are similar for obtaining 2-dimensional predictive profile images of patients with Class III malocclusion treated with orthognathic surgery.

Evaluation of Satisfaction of Patients Rehabilitated With Zygomatic Fixtures

Purpose: The aim of this study was to evaluate the satisfaction of patients rehabilitated with zygomatic fixtures and prosthesis with immediate loading.Materials and Methods: The study selected patients who were rehabilitated with zygomatic implants at the clinic of the Latin American Institute for Dental Research and Education (ILAPEO. Curitiba-PR. Brasil) between 2005 and 2009. The patients were asked to answer a control-questionnaire during their follow-up visits. Data were collected regarding the level of patient satisfaction, reason for dissatisfaction, number of post-operative clinical sessions, and the type of complication. Sixteen patients were selected: 10 females and 6 males.Results: Half of the patients were completely satisfied while the other half were satisfied with some complaints. The complaints were related to hygiene, esthetics, phonetics, and discomfort during chewing. Regarding the post-operative evaluation, 50% of the patients were attended due to the prosthesis (62.5%) and the implant (37.5%).Conclusions: The treatment with zygomatic fixtures is predictable and reliable. The patients were satisfied both with implants and prosthesis. (C) 2012 American Association of Oral and Maxillofacial Surgeons J Oral Maxillofac Surg 70: 314-319, 2012

Occurrence of Odontogenic Infections in Patients Treated in a Postgraduation Program on Maxillofacial Surgery and Traumatology

This study assessed the occurrence and characteristics of oral and maxillofacial infections in patients treated at a Brazilian oral and maxillofacial emergency service during a 7-year period. The clinical files of all patients treated at the Oral and Maxillofacial Surgery and Traumatology Service of the Aracatuba Dental School, São Paulo State University, Brazil, between 2002 and 2008 were reviewed. From a population of 3645 patients treated in this period, the study sample consisted of 93 subjects who presented odontogenic infections. Data referring to the patients' sex, age, medical history, and the etiology, diagnosis, complications, drug therapy/treatment, and evolution of the pathologic diseases were collected and analyzed using the Epi Info 2000 software. of these patients, 54 were men (58.1%) and 39 were women (41.9%). Most patients were in the 31- to 40-year-old (20.7%) and 21- to 30-year-old (19.6%) age groups. The most frequent etiology was pulp necrosis due to caries (80.6%). Regarding the treatment, antibiotics were administered to all patients, surgical drainage was done in 75 patients (82.4%), and 44 patients (47.3%) needed hospital admission. First-generation cephalosporin alone or combined with other drugs was the most prescribed antibiotic (n = 26) followed by penicillin G (n = 25). Most patients (n = 85, 91.4%) responded well to the treatment. Five cases had complications: 3 patients needed hospital readmission, 1 case progressed to descending mediastinitis, and 1 patient died. Odontogenic infections can be life-threatening and require hospital admission for adequate patient care. Complications from odontogenic infections, although rare, may be fatal if not properly managed.

Computer-Guided Surgery in Implantology: Review of Basic Concepts

The aim of the present study was to conduct a critical literature review about the technique of computer-guided surgery in implantology to highlight the indications, purposes, immediate loading of implants and complications, protocol of fabrication, and functioning of virtual planning software. This literature review was based on OLDMEDLINE and MEDLINE databases from 2002 to 2010 using the key words "computer-guided surgery" and "implant-supported prosthesis." Thirty-four studies regarding this topic were found. According to the literature review, it was concluded that the computer-assisted surgery is an excellent treatment alternative for patients with appropriate bone quantity for implant insertion in complete and partially edentulous arches. The Procera Nobel Guide software (Nobel Biocare) was the most common software used by the authors. In addition, the flapless surgery is advantageous for positioning of implants but with accurate indication. Although the computer-guided surgery may be helpful for virtual planning of cases with severe bone resorption, the conventional surgical technique is more appropriate. The surgical guide is important for insertion of the implants regardless of the surgical technique, and the success of immediate loading after computer-guided surgery depends on the accuracy of clinical and/or laboratorial steps.

Reconstruction of Skull Defects: Currently Available Materials

The restoration and recovery of a compromised skull continues to be a challenge to craniofacial surgeons and neurosurgeons. Different operative techniques and implant materials are being used to reconstruct the rigid framework of the skull. However, no currently available materials satisfy all of these criteria. According to this premise, the aim of this study was to report on the currently available materials for the reconstruction of the cranial vault and to describe their main characteristics, advantages, and disadvantages. Although the use of the materials discussed in this study is clearly positive for the reconstruction of skull defects and cranioplasties, there is a need for more complex studies and research into developing these materials to achieve all the ideal prerequisites stipulated by the scientific community and to evaluate their properties and aesthetic and functional results in the long term.
