The type and severity of trauma injury; and the etiology of facial fractures is different according to the population studied. With the more stringent traffic laws, there was a reduction of facial fractures caused by automobiles accidents, but it still appears as the main cause and the prevalence of male and facial fractures. These fractures of the mandible condyle correspond 25-35% of mandible fractures diagnosed through radiographs projection Towne, panoramic and computed tomography. The same feature as the main etiological factors trauma by direct assault, car accidents, bicycle fall, fall from height and injury by firearms. Diagnosis of condylar fractures in pediatric patients should be very strict by the difficulty of obtaining information about the history of trauma, especially due to age of the patients affected. The etiology of condylar fractures in pediatric patients varies according to the stage of the child’s life (the 0-6 year of life and from the 6th year of life). The treatment of these fractures, especially in pediatric, when mishandled can cause permanent deformity. The treatment can be surgical or conservative, and should be made after the analysis of the age and gender of the patient, etiology and clinical conditions of fracture, time from the trauma, and dental occlusion. In pediatric patients, in most cases, the of first choice treatment is the conservative approach, because the ability of bone growth and bone remodeling that occurs.

Osseointegrated Implants

The use of osseointegrated implants has been increasingly widespread in the adult population, however in children there is a certain lack in the literature on the application of this technique. The bone growth and development factor must be well analyzed, and the pediatric dentist must be able to suggest the use of this treatment option for oral rehabilitation, when necessary. This article discusses bone growth and development of the craniofacial region, presents relevant aspects of the literature and discusses the use of this technique in pediatric patients.

OBJECTIVEFor patients with moyamoya disease (MMD), surgical intervention is usually required because of progressive occlusion of the internal carotid artery. The indirect bypass method has been widely accepted as the treatment of choice in pediatric patients. However, in adult patients with MMD, the most effective treatment method remains a matter of debate. Here, the authors compared the clinical outcomes from MMD patients treated with either extracranial-intracranial arterial bypass (EIAB; 43 hemispheres) or modified encephaloduroarteriosynangiosis (mEDAS; 75 hemispheres) to investigate whether mEDAS is an effective surgical method for treating adults with symptomatic MMD.METHODSA comparative analysis was performed in patients treated using either mEDAS or EIAB. Collateral grading, collateral vein counting, and symptom analysis were used to assess the outcome of surgery.RESULTSSeventy-seven percent (58/75) of mEDAS cases and 83.7% (36/43) of EIAB cases in the analysis experienced improvement in their symptoms after surgery. Furthermore, patients in 98.7% (74/75) of mEDAS cases and those in 95.3% (41/43) of EIAB cases exhibited improved collateral grades. Increases in regions of perfusion were seen after both procedures.CONCLUSIONSModified EDAS and EIAB both result in positive outcomes for symptomatic adults with MMD. However, when considering the benefit of both surgeries, the authors propose mEDAS, a simpler and less strenuous surgery with a lower risk of complications, as a sufficient and safe treatment option for symptomatic adults with MMD.

Shock Peening

Current biocompatible metals such as steel and titanium alloys have excellent corrosive properties and superior strengths. However, their strengths are often too high and as a result have a negative effect on the body. Therefore, Magnesium (Mg) alloys with relatively low strengths are ideal biocompatible metallic materials. The problem with Mg implants is how to control corrosion rates so that the degradation of Mg implants may match with bone growth. The high compressive residual stress induced by laser shock peening (LSP) has a great potential to slow down the corrosion rate. LSP is a known surface treatment method to impart compressive residual stress in subsurface of a metal. Therefore, LSP was initiated in this study to investigate surface topography and integrity produced by peening a Mg alloy. A 3D semi-infinite simulation has also been developed to predict the topography and residual stress fields produced by sequential peening. The dynamic mechanical behavior was modeled using a user material subroutine of the internal state variable plasticity model. The temporal and spatial peening pressure was modeled using a user load subroutine. The simulated dent agrees with the measured dent topography in terms of profile and depth. Sequential peening was found to increase the tensile pile up region which is critical to tribological applications. The predicted residual stress profiles are also presented.

Abstract Background The FED method (Fixation, Elongation, Derotation) is a treatment method approach to Patients with scoliosis. The FED method is especially established in Spain and Poland, whereby in Germany it is less well-known. Nevertheless the FED method is within the scope of a research project (Project Number: 19200 BR/3). The purpose of the paper is to characterize the FED method and to highlight the specificities in contrast to the Schroth method, which is international established and especially in Germany. Methods This systematic literature research was conducted in Nov 2017–Jan 2018. Therefore common medical and physiotherapeutic databases were used. Furthermore there was a hand search in selected scientific journals. Only a small number of relevant references were identified. That is why the respective authors were asked to provide the full-texts of their papers and to recommend further references. Results A total of 378 references were identified. After removing duplicates and the content-related selection, 19 references were deemed to be relevant. Based on the analysis of this relevant literature, the FED method was comprehensively characterized. First of all the general structure of the FED method and the scientific evidence for its effectiveness was described. And as a result of the literature research, the operating principles of the FED method were pointed out. Then these operating principles were discussed in comparison with the Schroth method. The Schroth method based on sensomotoric and kinesthetic principles and the correction of the pathologic posture was performed by selective muscle activation and breathing-pattern. Thus, the posture correction will be performed by the patients (auto correction). Compared to the Schroth method, the FED method implements the posture correction by the FED-device. This correction is influenced by mechanical forces with a comparatively high strength and intensity. The repetitive mechanical correction stimulates the sensomotoric system. And due to trophic/biochemical adaptations, the physiological bone growth will be stimulated. Conclusion In total the authors want to clarify, that both treatment methods (Schroth method, FED method) supposed to be applied in consideration of the preconditions of the patients and the pursue of the different treatment goals. Thus, the implementation of treatment methods should be used according to the individual treatment demand and on different stages in the treatment process.

Background/Aim. Vesicouretheral reflux (VUR) is an inherited abnormality of the urinary tract caused by dysfunction of vesicouretheral junction frequently accompanied by recurrent urinary infection. The optimal treatment method of VUR is still controversial. The aim of the study was to analyze medical charts of children with VUR with special focus on the results of endoscopic treatment with Deflux. Methods. This retrospective study analyzed the medical charts of all children diagnosed with VUR at the Institute for Children and Youth Health Care of Vojvodina, in five years period. The analyzed data were: age, gender, grade, bilateral or unilateral presence of reflux, distribution to the sides of the body, urinary tract infections, associated anomalies and complications of VUR, treatment methods and the success rate of endoscopic correction with Deflux. Data processing was performed using the standard statistical methods. Results. The study included 167 patients (101 females and 66 males) with 231 refluxing ureters. The patients age at diagnosis was 1 month to 18 years (mean 4.6 years). Frequencies of different grades of VUR at initial investigation were: 17%, 27%, 22%, 21% and 13% for grades I to V, respectively. VUR was unilateral in 103 patients (left in 65 and right in 38), and bilateral in 64. Urinary tract infections were present in 78.4% of patients, reflux nephropathy in 38.3%, hypertension in 3.0%, chronic renal insufficiency in 4.8%, associated anomalies in 39.5% of patients. The treatment method was recorded in 154 cases. Medically were treated 80 patients, and surgically 74. Endoscopic injection of Deflux was carried out in 59 patients. From 79 ureters treated, five had grade I reflux, 11 grade II, 23 grade III, 27 grade IV, and 13 grade V. In 46 patients Deflux injection was carried out once. A second injection was required in eight, and third injection in five patients. Reflux was absent in 42 of the treated patients (71.2%) and 15 patients (25.4%) had a decreased grade of reflux after the treatment. Overall success rate was 96.6%. Conclusion. Endoscopic subureteral injection of Deflux is a minimally invasive method for VUR treatment in pediatric patients.
