Massive hematothorax after thoracic spinal manipulation for acute thoracolumbar pain.

Spinal manipulation usually represents a widely used and effective method for physicians in order to relieve acute patient pain and muscular dysbalance. Although life-threatening complications (e.g.

Expression of hedgehog signalling pathway in anaplastic thyroid cancer.

The purpose of this work is to study the activation of the hedgehog signalling pathway is associated with tumour progression in various types of cancer, hence the development of specific antagonists raises hope for new therapeutic strategies. Therefore, the expression of hedgehog pathway components in anaplastic thyroid cancer (ATC) and effects of the hedgehog inhibitor Cyclopamine on ATC cells were investigated in this study. Expression of the ligand Sonic Hedgehog (SHh), the transmembrane protein Smoothened (Smo), the receptor Patched (Ptc) and the target gene Gli-1 was evaluated in two ATC cell lines (Hth 74, C643) by RT-PCR and in tumour specimens by immunohistochemistry.

Combined inhibition of cellular pathways as a future therapeutic option in fatal anaplastic thyroid cancer.

Conventional treatment by surgery, radioiodine, and thyroxin-suppressive therapy often fails to cure anaplastic thyroid cancer (ATC). Therefore several attempts have been made to evaluate new therapy options by use of "small molecule inhibitors". ATC was shown to respond to monotherapeutic proteasome and Aurora kinase inhibition in vitro as well as in xenotransplanted tumor cells.

Targeting the proteasome as a promising therapeutic strategy in thyroid cancer.

Background And Objectives: Targeting the ubiquitin-proteasome system by using proteasome inhibitors represents a novel approach for cancer therapy. Anaplastic thyroid cancer (ATC), a subtype of thyroid cancer (TC), fails to respond to conventional TC treatment. Here we investigated the effects of bortezomib on TC in vitro.
