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...

Background: Eckardt score and Achalasia quality of life (ASQ) are two scoring systems used in achalasia. This study tries to compare these scores assessing the severity disease before 3 months after initiation treatment. Methods: 40 patients newly diagnosed with achalasia cardia were included this study. ASQ calculated at time presentation. Patients underwent either Laparoscopic Heller myotomy ...

gus characterized by increased pressure in the lower sphincter and incomplete relaxation after swallowing (1). Classical symptoms include dysphagia, regurgitation, chest pain and weight loss. Cardiovascular complications of achalasia are very rare (2). We report a patient with achalasia in whom swallowing induced bradycardia and atrioventricular (AV) complete block during ingestion of food with...

Prior to the widespread adoption of electrical and electronic controls, buildings often used pneumatic control systems. Large and powerful compressors drove 3psi to 15psi pneumatic signals throughout a plant and these pneumatic lines connected to pneumatically controlled valves and pneumatically controlling valves in order to drive proportional controls and actuators throughout the building, al...

Pneumatic actuators convert pneumatic energy into mechanical motion. This motion can be linear or rotary. Linear motion is feasible with pneumatic cylinders (e. g. single-acting cylinder, double-acting cylinder, rodless cylinder) and pneumatic artificial muscles (PAMs). Pneumatic artificial muscle is the newest and most promising type of pneumatic actuators. PAM is a membrane that expands radia...

OBJECTIVE To show the efficacy and comfort of pneumatic bag packing after the endoscopic nasal surgery. Pneumatic bag packing may be recommendable in terms of comfort and efficacy after endoscopic nasal surgery. Significant findings: There were statistical significant differences between the pneumatic bag packing and the expansive sponge packing regarding subjective symptoms and objective findi...

introduction: abnormal uterine bleeding (aub) is among the most complex gynecological problems, especially during the middle and old age. the aim of this study was to assess the pathological findings in endometrial curettage samples of abnormal uterine bleeding and the risk factors associated with them. methods: in our cross-sectional study, we included all the referring women with aub complain...

This project aims to develop a novel large stroke asymmetric pneumatic servo system of a hardware-in-the-loop for path tracking control under variable loads based on the MATLAB Simulink real-time system. High pressure compressed air provided by the air compressor is utilized for the pneumatic proportional servo valve to drive the large stroke asymmetric rod-less pneumatic actuator. Due to the p...

AIM Previous research has shown that general practitioners (GPs) rarely use pneumatic otoscopy or tympanometry as recommended by best practice guidelines for diagnosing otitis media. The purpose of this study was to determine whether a multimodal, interactive training workshop on the techniques of pneumatic otoscopy and tympanometry would improve the confidence of GPs for the diagnosis of otit...
