Fibrosis Associated with Retroperitoneal Abscess after Multimodal Treatment of Cervical Carcinoma - A Case Report and Brief Review of the Literature.

Background: The multimodal treatment options for cervical carcinoma are represented by either radical hysterectomy associated with pelvic lymph node dissection, pelvic radiation therapy or chemotherapy. Inflammatory and post-neoplasia fibrosis associated with post-radiation fibrosis syndrome (RFS) and lymphedema may cause severe complications and quality of life alteration. Case report: Here we present a case of a 40-year-old woman, seven months after completing standard treatment for squamous cervical cancer FIGO IIA1 with a negative impact on the quality of life due to an important abdominal and retroperitoneal fibrosis leading to significant gastrointestinal symptoms. Over a year, a symptomatic intraabdominal collection and a retroperitoneal abscess were managed in the surgery department by percutaneous drainage and exploratory laparotomy. Bowel obstruction, abscessed pelvic tumor, left colocutaneous and colocolic fistula, intra-abdominal adhesions and left uretero-hydronephrosis were found. Postoperatively, the evolution was unfavorable with upper gastrointestinal bleeding probably due to entero-mesenteric fistula followed by death. Conclusion: Fibrosis can contribute to unfavorable clinical evolution with multiple complications and difficult management. Intra- and retroperitoneal fibrosis, neoplasia and post radiation enteropathy associated with pelvic inflammatory disease make the surgical approach difficult. Diagnosis of retroperitoneal abscess may be challenging due to nonspecific symptoms.

Electron microscopy analysis of different orthodontic brackets and their adhesion to the tooth enamel.

This study proposed to evaluate the surface morphology of different types of orthodontic brackets and the characteristics of their adhesion to the tooth enamel. There have been taken into study six metallic, five ceramic and one polymeric bracket from different brands (Ormco, Lancer, Leone, Damon, 3M, Ultradent, American Orthodontics, Rocky Mountain). The surface base of the each bracket it have been ESEM analyzed using scanning electron microscope Phillips XL-30 ESEM. There have been investigated several parameters that have a potential influence of the bracket-bonding agent interface joint: chemical composition, roughness, surface morphology and wideness. After ESEM analysis, the same metallic and ceramic brackets have been afterwards collated on extracted teeth and subjected to mechanical tests. After the mechanical testing, the samples were once again ESEM investigated. All fractures occurred in the area of the adhesive system, recording adhesive fractures of the tooth-composite resin and composite-bracket, cohesive fractures and both. The metallic brackets surfaces that are optima for a good adhesion is that of a mesh sand blasted and acid etched. From the esthetic brackets, the ceramic ones are superior to polymeric ones regarding bonding to teeth.

Intervention of the occlusion relations in the appearance of the modifications in sagittal and transversal plan in the anomalies of the class III angle.

During the development of the neuronic and visceral cranium, an important number of factors, not only genetic, but also functional, led to the apparition of some different aspects of growing at the level of each section: the basis of the cranium, the basis of the maxillary, dental alveolus, dental arch. All these "aggravating" or "compensatory" changes are added to the level of the occlusion plan, leading to the establishment of the occlusion relations in the three plans. From now on, the occlusion will directly influence the development at the level of the above-described sections.

Specific morphological aspects of the teeth and alveolar bone in Class II/2 malocclusion.

In the genesis of dental-maxillary anomalies both morphologic factors (of proven genetic origin) and functional factors (as added ethio-pathogenic elements) are incriminated. From this point of view, Class II/2 malocclusion, presents two morphologic factors whose genetic origin is certain and upon which functional factors have minor influence. These are: the morphology of the teeth and alveolar process in the anterior region of the maxilla and the type of rotation. The combination of the two generates a broad range of deep bite case variants.

The Romanian need of postgraduate specialization in dentistry considering the integration to the European Union.

Once that Romania became part of the European Union, conditions regarding the activity in dentistry changed, and open borders are now a fact that we have to accept. The Romanian activity in dentistry developed a lot after the 1990. being a result of private dental practice--which covers over 98% and also of material resources of patients that were asking for more performing dental treatments. In order to be able to face all this, the dentists followed many of postgraduate specializations. We have to consider as well that the situation of the Romanian dentists is not the best, because they had to face the dentists that got their certificates in Eastern countries, where they only had to pay a fee and not pass an exam. Also, the Romanians that wanted to specialize abroad were not able to do that because the National Dentists' Association was protecting their own colleagues.
