Einflüsse von genetischen Prädispositionen und Umweltfaktoren auf Erkrankungen des Menschen

In der klinischen Umweltmedizin stehen zur Zeit keine spezifischen diagnostischen Verfahren zur Verfügung, welche die Existenz umweltbedingter Gesundheitsstörungen oder Erkrankungen belegen können. Einen möglichen Ansatz zur Klärung dieses Problems kann die Erforschung ätiologischer Einflüsse genetischer Prädispositionen und Umweltfaktoren auf Erkrankungen des Menschen liefern. Daher wurde am Universitätsklinikum Aachen ein interdisziplinärer klinischer Forschungsschwerpunkt etabliert, welcher im Rahmen des Förderprogramms START der Medizinischen Fakultät der Rheinisch-Westfälischen Technischen Hochschule (RWTH) Aachen eine Anschubfinanzierung erhielt. Im Rahmen dieses Forschungsschwerpunktes werden in einem ersten Schritt die komplexen, ätiologischen Zusammenhänge der sogenannten Multiple Chemical Sensitivity (MCS), Polyposis nasi, Geruchsüber- und Geruchsunterempfindlichkeit, Sensibilisierungen auf Duft- und Aromastoffe sowie Atherosklerose untersucht. Basierend auf diesem Forschungsschwerpunkt wird die Etablierung eines Klinischen Forschungszentrums für Umweltmedizin mit dem Ziel der Entwicklung eines bundesweiten Kompetenznetzwerkes angestrebt

The course of spinal tuberculosis (Pott disease): Results of the multinational, multicentre Backbone-2 study

PubMed ID: 26232534We aimed to describe clinical, laboratory, diagnostic and therapeutic features of spinal tuberculosis (ST), also known as Pott disease. A total of 314 patients with ST from 35 centres in Turkey, Egypt, Albania and Greece were included. Median duration from initial symptoms to the time of diagnosis was 78 days. The most common complications presented before diagnosis were abscesses (69%), neurologic deficits (40%), spinal instability (21%) and spinal deformity (16%). Lumbar (56%), thoracic (49%) and thoracolumbar (13%) vertebrae were the most commonly involved sites of infection. Although 51% of the patients had multiple levels of vertebral involvement, 8% had noncontiguous involvement of multiple vertebral bodies. The causative agent was identified in 41% of cases. Histopathologic examination was performed in 200 patients (64%), and 74% were consistent with tuberculosis. Medical treatment alone was implemented in 103 patients (33%), while 211 patients (67%) underwent diagnostic and/or therapeutic surgical intervention. Ten percent of the patients required more than one surgical intervention. Mortality occurred in 7 patients (2%), and 77 (25%) developed sequelae. The distribution of the posttreatment sequelae were as follows: 11% kyphosis, 6% Gibbus deformity, 5% scoliosis, 5% paraparesis, 5% paraplegia and 4% loss of sensation. Older age, presence of neurologic deficit and spinal deformity were predictors of unfavourable outcome. ST results in significant morbidity as a result of its insidious course and delayed diagnosis because of diagnostic and therapeutic challenges. ST should be considered in the differential diagnosis of patients with vertebral osteomyelitis, especially in tuberculosis-endemic regions. Early establishment of definitive aetiologic diagnosis and appropriate treatment are of paramount importance to prevent development of sequelae. © 2015 European Society of Clinical Microbiology and Infectious Diseases
