This paper presents an analysis of the major mechanical component (the thorax) of the micromechanical flying insect (MFI), a centimeter sized aerial vehicle currently in development at UC Berkeley. We present a description of the kinematics of the mechanism which converts piezoelectric actuation into complex 3D wing motion. A complete non-linear modeling of the system based on the Lagrangian en...

We report the first case in Korea of a chronic expanding hematoma, which presented as a huge mass in the pleural cavity. A 67-year-old woman exhibiting a slowly-expanding intrathoracic mass, as revealed by a chest radiograph, was admitted to our hospital. The patient had undergone a pneumonectomy 37 years earlier during treatment for pulmonary tuberculosis. Computed tomography revealed a huge m...

Keeping up to date with scientific developments in any field of medicine is challenging, and chronic obstructive pulmonary disease (COPD) is no exception. Thorax has played an important part in the communication of key developments to its readership. In this article we review original research published in the journal over the last 2-3 years. We consider scientific and clinical developments in ...

Volume 10 • Number 1 • July 2002 51 Authors Peter Gibbons and Philip Tehan are both osteopathic practitioners and teachers who use high velocity, low amplitude manipulation (HVLA) techniques. They have produced this text in response to the relative absence of a dedicated HVLA text in the manual therapy field. As a student of osteopathy I understand how frustrating it can be learning HVLA techni...

Over the past decade, there has been an increase in endoscopic procedures within the thorax for diagnostic and therapeutic purposes. Each has its indications, techniques and complications. However, the one common denominator is that there is always the possibility that thoracotomy may be necessary. Occasionally, particularly if considerable haemorrhage occurs, thoracotomy may be required immedi...

Helical computed tomography (HCT) allows for volume acquisition of the entire thorax during a single apnoea. Combination of HCT acquisition with synchronous vascular enhancement gives rise to HCT angiography (HCTA). In the last decade, HCT and HCTA have revolutionized the diagnosis of thoracic diseases, modifying many diagnostic algorithms. Because HCT provides for a true volume acquisition fre...

The thoracic spine has a primary dorsal convexity (Fig. 1) associated with intrauterine life – a phylogenetic kyphosis – whereas the cervical and lumbar spine have a compensatory lordosis. The 12 thoracic vertebrae are intermediate in size between those in the cervical and lumbar regions. They are composed of a vertebral body – a cylindrical ventral mass of bone – continuing posteriorly into a ...

Pneumomediastinum and subcutaneous emphysema of the neck and thorax can occur exceptionally following a dental procedure. A case is described of acute subcutaneous emphysema of the lateral region of the neck and thorax associated with pneumomediastinum during a dental extraction with an air and water cooled turbine burn drill.
