introduction: transtibial amputation is the most common amputation in lower limbs. volume loss of residual limb occurs during daily use of prostheses, which results in pistoning between residual limb and prosthetic socket. the goal of this study was to design and fabricate a pneumatic suspension system in transtibial supracondylar prostheses and to evaluate its effect on residual limb pistoning...

BACKGROUND Tympanometry and pneumatic otoscopy are recommended for diagnosis of otitis media, but are not frequently used by general practitioners (GPs). We examined how, after targeted short training, GP diagnosis and management of childhood ear disease was changed by the addition of these techniques to non-pneumatic otoscopy. We further explored factors influencing the uptake of these techniq...

background achalasia is the most recognized motor disorder of the esophagus.because it is an uncommon disease, most studies have reviewed small numbers of patients. here, we report demographic, clinical features and treatment outcomes in 700 achalasia patients. methods in all patients, diagnosis was established based on clinical, radiological, endoscopic and manometric criteria. a questionnaire...

background: achalasia is the most recognized esophageal motor disorder with an unknown etiology. symptoms rather than physical findings are hallmarks of the disease. modalilies for treatment include pharmacologic, botulinum toxin injection, pneumatic dilation and surgery. materials and methods: to review the diagnostic and therapeutic options currently available for achalasia. a medline search ...

achalasia is a well- defined esophageal motor disorder. graded pneumatic dilation using rigiflex ballon is one of the therapeutic modalities that had not been evaluated in a large long-term study. we aimed at evaluating long-term efficacy of graded rigiflex pneumatic dilation in the treatment of achalasia. symptomatic patients with achalasia who had been referred to our center were consecutivel...

In the past, Aedes atropalpus was limited to those areas of the eastern U.S. and Canada that had rivers or shorelines with large rocks containing rock pools. In the last 10 years, many new records of larval breeding in scrap tires have accumulated. We present records of larval breeding in non-rock pool containers for 54 counties; most are far from the original range. The species has not only fo...
