Frühes Ovarialkarzinom

Patients with early ovarian carcinoma have a much better survival outcome than patients with more advanced disease. Comprehensive surgical staging is crucial for the determination of prognosis and treatment planning. During 2003, the first randomized trials were published demonstrating that adjuvant platinum based chemotherapy improves recurrence free and overall survival. Current treatment recommendations are largely based on the results of these studies. Accordingly, systemic adjuvant therapy should be offered to patients with disease stage Ib or higher and to patients with moderately differentiated or undifferentiated tumors. Due to incomplete surgical staging, the stage of disease in the patients included in these studies is probably underestimated, and only a fraction of the actual advanced stage patients is included.     

Magenkarzinom – eine Infektionskrankheit

Gastric cancer still represents the second most common cause of gastrointestinal cancers in Germany. A disturbing issue is that at the time of diagnosis there are less than 15% of patients for whom a cure can be achieved. Nowadays, biological, histomorphological, molecular genetic and epidemiological data suggest that Helicobacter pylori eradication may lead to the prevention of gastric pre-neoplastic lesions and even gastric cancer. At present, eradication can be offered to selected patients and populations at increased risk, but more research is required before embarking on general and global H. pylori eradication for gastric cancer prevention. The main challenge is to determine how long mucosal abnormalities remain reversible and gastric cancer development can be halted.     

Three-Dimensional Soft Tissue Prediction Using Finite Elements

BACKGROUND AND AIM: The goal of this study was to analyze the validity and prediction accuracy of a newly-developed procedure for three-dimensional soft tissue prediction based on Finite Element Method, and to compare the results with prediction produced using an existing two-dimensional prediction program (Dentofacial Planner Plus). PATIENTS AND METHODS: In twelve patients who underwent combined surgical-orthodontic treatment, profile prediction was generated using both procedures preoperatively and then compared at predefined measurement points with the patient's actual postoperative soft tissue status. RESULTS: The deviations observed depended on the facial region, whereby the prediction errors for both procedures were much greater in the lower facial third than in the midfacial third. Calculating in all the measurement points, the mean horizontal prediction error was 0.32 mm for the Finite Element Method and 0.75 mm for the Dentofacial Planner Plus. Overall, we were able to demonstrate the new procedure's superior validity and quality of visualization. In addition to profile prediction, the procedure allows a differentiated three-dimensional assessment of esthetically important regions such as the cheeks, nasolabial folds and the nasal wings. Additional X-radiation is not necessary in this risk-free and stress-free procedure. CONCLUSION: Three-dimensional soft tissue prediction employing finite element modeling is a useful aid for implementing esthetically-optimized treatment planning.     

Wissenschaftliche Neurobildgebung in der Medizin

Neuroimaging has in recent years greatly contributed to our understanding of a wide range of aspects of central neurological diseases. These include the classification and localization of disease (e.g., in headache), the understanding of pathology (e.g., in Parkinson’s disease), mechanisms of reorganization (e.g., in stroke), and the subclinical progress of disease (e.g., in degenerative diseases). Apart form presurgical mapping, clinical applications of fMRI are limited. However, functional imaging enables the formulation of neurobiological hypotheses that can be tested clinically and is suited to test classical clinical hypotheses about how the brain works. Understanding the mechanisms and the site of pathology, e.g., in cluster headaches, will lead and has led to new therapeutic strategies. New methodological developments for neuroscientific applications are aimed at the integration of functional and morphological connectivity through a combination of magnetic resonance techniques (fMRI, DTI) and electrophysiological (EEG, MEG) recordings. In addition to stimulus-dependent activations, resting state activity has found increasing interest, for example, in sleep research and various psychiatric diseases (e.g., schizophrenia, borderline).     

Was verstehen wir unter Sucht?

In the past, addiction disorders were considered to be mainly substance use disorders. The main focus has been on dependence disorders. Dependence criteria do not differ substantially in the two main classification systems ICD and DSM, while harmful use (ICD) and abuse (DSM) criteria show much less concordance. Presently diagnostic criteria for behavioral addiction disorders are only available for pathological gambling, however, under the category of disorders of impulse control, while other disorders have to be categorized under disorders not otherwise specified. Evidence of neurobiological similarities implies that future ICD and DSM revisions, in addition to other needed changes, will group behavioral addiction and substance use disorders together.

Halswirbelsäule und Halsgefäße

The cumulative frequency of diminished stability of the major cervical arteries may be estimated between 10 and 25% in the general population. About 6% may be attributable directly to variations of the carotid arteries, and about 10% indirectly to alterations of the cervical spine, especially the atlas. Other developmental disturbances may also play a role.
