Objective Achalasia Cardia is treated by Pneumatic balloon dilatation, Heller's Myotomy and recently, by Peroral Esophagaeal Myotomy. This study reports the efficacy of pneumatic balloon dilatation as a non-surgical motility in achieving relief of dysphagia, clinical improvement and recurrence. Long-term complications were reported. Methods Eight hundred ninety two adult achalasia patients of...

Fetal bowel dilatation is an indirect sonographic sign of mechanical or functional bowel obstruction. The etiology of fetal bowel dilatation is a difficult prenatal diagnosis since ultrasound has limited accuracy for bowel evaluation. The authors describe a case of fetal bowel dilatation diagnosed in the third trimester.

Based on the notion of dilatation structure [2], we give an intrinsic treatment to sub-riemannian geometry, started in the paper [4]. Here we prove that regular sub-riemannian manifolds admit dilatation structures. From the existence of normal frames proved by Belläıche we deduce the rest of the properties of regular sub-riemannian manifolds by using the formalism of dilatation structures.

BACKGROUND The Ross operation is an alternative to mechanical aortic valve replacement in the young. Early dilatation of the pulmonary autograft root exposed to the systemic circulation has been reported. To define the prevalence of, risk factors for, and consequences of late autograft dilatation, outcome in all consecutive patients operated since May 1994 was reviewed. METHODS AND RESULTS Ni...

A patient with small bowel capillary dilatation and cirrhosis is reported. This patient had persistent, unexplained gastrointestinal bleeding. Small bowel capillary dilatation appears to be unique to patients with portal hypertension. The possible role of small bowel capillary dilatation in causing gastrointestinal bleeding is discussed.

abstract background: abnormal uterine bleeding (aub) is one of the most common complains in women of any age seeking gynecologic health care and needs early diagnosis and proper management due to its impacts on the quality of life. this study was conducted to investigate the cut-off value of endometrial thickness (et) by trans-vaginal ultra-sonography (tvus) and evaluate its accuracy in the dia...

kindler syndrome is a rare hereditary disorder that predominantly involves the skin and mucous membrane. acral skin blistering, progressive photosensivity, skin atrophy and poikiloderma that begin from infancy and childhood are considered to be characteristic manifestations. urethral, anal, esophageal, mouth and laryngeal mucosa may be involved in this syndrome, thus periodontitis and gingival ...

Aortic stenosis is the most common valvular heart disease affecting up to 4% of the elderly population. It can be associated with dilatation of the ascending aorta and subsequent dissection. Post-stenotic dilatation is seen in patients with AS and/or aortic regurgitation, patients with a haemodynamically normal bicuspid aortic valve and following aortic valve replacement. Controversy exists as ...

A dilatation structure is a concept in between a group and a differential structure. In this article we study fundamental properties of dilatation structures on metric spaces. This is a part of a series of papers which show that such a structure allows to do non-commutative analysis, in the sense of differential calculus, on a large class of metric spaces, some of them fractals. We also describ...
