BACKGROUND Aspiration pneumonia has been a growing interest in an aging population. Anaerobes are important pathogens, however, the etiology of aspiration pneumonia is not fully understood. In addition, the relationship between the patient clinical characteristics and the causative pathogens in pneumonia patients with aspiration risk factors are unclear. To evaluate the relationship between the...

Pulmonary fibrosis can be experimentally induced in small rodents by bleomycin. The antibiotic is usually administered via the intratracheal or intranasal routes. In the present study, we investigated the oropharyngeal aspiration of bleomycin as an alternative route for the induction of lung fibrosis in rats and mice. The development of lung injury was followed in vivo by ultrashort echo time m...

Computational fluid dynamics was used to investigate particle aspiration efficiency in low-moving air typical of occupational settings (0.1-0.4 m s(-1)). Fluid flow surrounding an inhaling humanoid form and particle trajectories traveling into the mouth were simulated for seven discrete orientations relative to the oncoming wind (0°, 15°, 30°, 60°, 90°, 135° and 180°). Three continuous inhalati...

BACKGROUND Aspiration is a common complication in acute stroke patients and is strongly associated with a poor outcome. Due to an insufficient sensitivity and specificity of clinical bedside tests, further refinements are needed to improve the accuracy of clinical aspiration screening in acute stroke. OBJECTIVE To assess the ability of the simple 2-step swallowing provocation test (SPT) to de...

OBJECTIVES To review the accuracy of fine-needle aspiration cytology in diagnosing non-toxic thyroid nodules and determine what factors are predictive of malignancy in patients with indeterminate cytology results. DESIGN Retrospective study. SETTING Regional hospital, Hong Kong. PATIENTS Patients with non-toxic thyroid nodules undergoing thyroidectomy from December 1999 to December 2003. ...

The aim of the present study was to evaluate the anaesthetic effect during oocyte aspiration of a paracervical block (PCB) in combination with either electro-acupuncture (EA) or intravenous alfentanil. In all, 150 women undergoing in-vitro fertilization (IVF) and embryo transfer were randomized to receive either EA plus PCB or alfentanil plus PCB. Visual analogue scales (VAS) were used to evalu...

BACKGROUND Megaesophagus carries a poor to guarded prognosis due to death from aspiration pneumonia. Options for medical management of regurgitation are limited to strategic oral or gastrostomy tube feeding. OBJECTIVES To describe the use and efficacy of intermittent esophageal suctioning to prevent regurgitation and associated episodes of aspiration pneumonia in dogs with megaesophagus. AN...

This paper describes the results of transproctoscopic fine needle aspiration cytology in the diagnosis of rectal lesions. Fifty one consecutive patients referred with a presumptive diagnosis of rectal mass were subjected to proctoscopic examination when fine needle aspiration cytology, brush cytology and biopsy samples were taken. Of the 30 patients of malignancy of rectum in whom all the three...

we report an unusual case of primary hydatid cyst of the mandibular angle without glands involvement, in the left supraclavicular region of the neck with no involvement of any other regions of the body. in july2012, a25-yr old woman, from golestan province, northeast iran was admitted to ourentclinic, with one-year history of a progressively increasing swelling, pain and gradually growing mass ...
