To relate exposure to adverse health effects, it is necessary to know where particles in the submicron range deposit in the respiratory tract. The possibly higher vulnerability of children requires specific inhalation studies. However, radio-aerosol deposition experiments involving children are rare because of ethical restrictions related to radiation exposure. Thus, an in vivo study was conduc...

Pain in the thoracic region of the spine is a common complaint, which can be as disabling as cervical and lumbar pain (Edmonston & Singer 1997). There are reports in the literature of presentations involving acute cervical ‘locked facet joints’ as well as acute lumbar ‘locked facet joints’ (Maitland 1978; Exelby 2001). Although there are a multitude of conditions that can arise from the thoraci...

OBJECTIVE To characterize biomechanical differences in gait between dogs with and without an amputated thoracic limb. ANIMALS Client-owned dogs (16 thoracic-limb amputee and 24 quadruped [control] dogs). PROCEDURES Dogs were trotted across 3 in-series force platforms. Spatial kinematic and kinetic data were recorded for each limb during the stance phase. RESULTS Amputees had significant i...

Basic knowledge about the thoracic spinal flexibility is limited and to the authors' knowledge, no in vitro studies have examined the flexibility of every thoracic spinal segment under standardized experimental conditions using pure moments. In our in vitro study, 68 human thoracic functional spinal units including the costovertebral joints (at least n = 6 functional spinal units per segment fr...

BACKGROUND The association of bronchial carcinoid tumours with carcinoid syndrome is extremely rare especially in the absence of metastasic disease, and the angioedema is not a typical sign of this syndrome. METHODS AND RESULTS We report the case of a 39 year-old woman referred to our allergy department with recurrent episodes of angioedema. The aetiological study of angioedema did not show e...

Intracranial germ cell tumours are rare. The incidence of primary intracranial yolk sac tumour is even more uncommon, with only two reported cases being associated with Down's syndrome in the English literature. This report details the findings of yolk sac tumour in the pineal region affecting a 22 year old Chinese man with Down's syndrome. Histology revealed yolk sac tumour with only a solid p...

Introduction: Early recurrence of hepatocellular carcinoma (HCC) is a major risk factor affecting survival even after hepatectomy. Many clinical, biochemical parameters and pathological grading like fibrosis 1 index have been used for risk stratifying HCC. However not many studies have combined all of them. It is therefore important to risk stratify HCC especially with newer PE...

Solitary fibrous tumour (SFT) is a rare oncological entity that most often arises in the pleura. Over the past 10 years, the tumour has been described at numerous extrapleural locations. We present the case of a 42-year-old female Caucasian patient with an extrapleural SFT located at the anterior thoracic wall for 22 years, with atypical histological characteristics and clinical features of mal...
