Investigation of bone conditions for orthodontic anchorage plates in the anterior mandible.

Objectives: The clinical success of orthodontic anchorage plates depends on the stability of the miniscrews used for fixation. For good stability, the application site must provide bone of good quantity and quality. This study was performed to analyze bone quantity for orthodontic anchorage plates in the anterior mandible.

Geometric accuracy of a newly developed cone-beam device for maxillofacial imaging.

Objective: The aim of this study was to determine the geometric accuracy of scans obtained with a newly developed cone-beam computed tomography (CBCT) device in comparison with a multidetector row computed tomography (MDCT) scanner.

Study Design: Cone-beam scans were obtained with the preretail version of a newly developed compact size device with a scan volume of 15 x 15 x 15 cm. Conventional CT scans for comparison were performed with a 6-detector row CT scanner.

Transbrachial thrombolysis, PTA and stenting in the lower extremities.

We present an analysis of 37 interventions in the arteries of the lower limbs via a transbrachial arterial approach. Twenty-six patients (42-79 years) underwent 37 interventional procedures in the lower extremities (iliac n = 6, iliac + femoro-popliteal n = 1, femoro-popliteal n = 30) with a vascular approach via the brachial artery (33 left sided, 4 right sided, introducer sheath 4-7 F). The transbrachial approach was chosen to avoid puncture of femoral bypass graft material.

Lymph node size and metastatic infiltration in non-small cell lung cancer.

Background: Preoperative lymph node staging of lung cancer by CT relies on the premise that malignant lymph nodes are larger than benign ones. Lymph nodes > 1 cm in size are regarded as metastatic nodes. The surgical approach and potential application of neoadjuvant therapy regimens are dependent on this evaluation.
