BACKGROUND Endoscopic sphincterotomy (EST) combined with large-balloon dilation (LBD) has been proposed as an alternative to manage large bile duct stones. However, recent reports indicate that LBD without EST may be safe and effective in this setting. METHODS One hundred thirty-one patients with large common bile duct (CBD) stones 12 mm in size or larger underwent LBD alone (n=62) or EST plu...

Keywords: Powder dispersion Impact angle Agglomerates Computational fluid dynamics Discrete element method a b s t r a c t This paper numerically investigated the mechanisms of powder de-agglomeration on mechanical impaction, aiming to explain the experimental observations in our previous study (Adi et al., 2010). A numerical model based on a coupled computational fluid dynamics (CFD) and discr...

Hematological and biochemical parameters were determined in 82 West African Dwarf goats with foreign body rumen impaction (FBR) and 40 normal WAD goats without foreign body rumen impaction (WFBR) in order to evaluate their influence on the etio-pathogenesis of rumen impaction. The mean PCV (26.22%), RBC (9.03 X 106/µL), Hb (8.38g/dl) and MCHC (32.20g/dl) were significantly lower in FBR than in ...

Background Impacted third molars may be responsible for various problems within the oral cavity. Impaction may be due to inadequate space or varied angulations. Assessment of variables contributing for impaction may influence the fate of impacted third molars. MethodologyRetrospective analysis of panoramic radiographs of adolescents in Indian population subpopulation was done to evaluate angula...

As impacted permanent maxillary cuspids occur in 1-2% of the population, the general dentist should know the signs and symptoms of this condition and the interceptive treatment. Features of buccal or palatal cuspid impaction include lack of canine bulges in the buccal sulcus indicating a lingual eruption path and possible impaction; lack of symmetry between the exfoliation and eruption of cuspi...

We studied various aspects of graft impaction and penetration of cement in an experimental model. Cancellous bone was removed proximally and local diaphyseal lytic defects were simulated in six human cadaver femora. After impaction grafting the specimens were sectioned and prepared for histomorphometric analysis. The porosity of the graft was lowest in Gruen zone 4 (52%) and highest in Gruen zo...

tooth impaction rarely occurs in primary dentition. most of the primary teeth impactions are seen in second molars. the purpose of this article is to present a 4-year-old girl with bilateral impaction of inverted primary maxillary central incisors which trauma had displaced their tooth germ before erupting.

Chronic constipation is a common condition which may result in fecal impaction. A 13-year-old male with chronic constipation and encopresis presented with fecal impaction for three weeks. The impaction caused abdominal pain, distension, encopresis, and decreased oral intake. He was found in severe distress with non-pitting edema of his feet and ankles along with perineal edema. The pedal edema ...
