objectives: bloating is a common and bothersome gastrointestinal symptom. despite its high prevalence, associated costs, and effects on the quality of life, very few studies have reported the epidemiology of bloating in iran. through this systematic review, findings and limitations of the current research will be discussed. methods: in march 2012, we searched pubmed, google scholar, scientific ...

â  background hirschsprung’s disease (hd) is a congenital disease in which intesâ­tinal ganglionic cells are absent, leading to intestinal obstruction. the disease has various clinical manifestations and different lengths of bowel may be involved. our aim was to study hirschsprung’s clinical presentations and its rate of intestinal involvement in hospitalized patients in a six year course s...

The maximum volume of air tolerated within a rectal balloon was less in colitic patients than in normal subjects (p < 0 001). Smaller volumes were tolerated by patients with a spontaneously bleeding mucosa than by those with less severe inflammation (p <0 001). Severe urgency of defaecation with incontinence was experienced by about half those with spontaneous mucosal haemorrhage butwas infrequ...

PURPOSE To assess the relationship between mandibular asymmetry and disorders of the temporomandibular joint. METHODS We used advanced imaging of the temporomandibular joint to distinguish different causes of mandibular asymmetry. MR imaging and arthrography were applied to the temporomandibular joints of 11 patients presenting with mandibular asymmetry. RESULTS Condyle hyperplasia was iden...

CT arthrography (CTa) and MR arthrography (MRa) are useful tools for the investigation of intra-articular hip disease. They are minimally invasive techniques with a very low rate of complications and can be performed safely. CTa or MRa can be performed after an intra-articular injection of diluted contrast, but both techniques can also be performed after a single injection. As radiologists we s...

UNLABELLED We propose a practical approach for performing arthrography with fluoroscopic or ultrasound guidance. Different approaches to the principal joints of the upper limb (shoulder, elbow, wrist and fingers), lower limb (hip, knee, ankle and foot) as well as the facet joints of the spine are discussed and illustrated with numerous drawings. Whenever possible, we emphasise the concept of ta...

Traumatic rupture of the tendon of the subscapularis muscle was documented as an isolated lesion in the shoulders of 16 men. The injury was caused either by forceful hyperextension or external rotation of the adducted arm. The patients complained of anterior shoulder pain and weakness of the arm when it was used above and below the shoulder level. They did not experience shoulder instability. T...

A fracture of the neck of the radius when the head is not ossified can be difficult to assess and treat. In a four-year-old child we suspected from the radiographs that there was an O'Brien type-III injury after trauma. Partial manual reduction of the non-ossified radial head was completed using the Métaizeau technique of intramedullary Kirschner (K-) wiring aided by intraoperative arthrography...

Distension of the rumen limits feed intake by livestock. Ruminal dysfunctions due to bloat, which causes distension by accumulation of excessive gas within the rumen, also reduce feeding. We hypothesized that excessive levels of rumen distension cause feed aversions and that preference increases for feeds eaten in association with recovery from bloat. To test these hypotheses, we determined whe...
