INTRODUCTION: This paper presents a model to predict bone ingrowth on cementless stems after a total hip arthroplasty. The post-operative fixation and the osseous-integration depend on the mechanical stability of the prosthesis. Actually, the micromovements between bone and stem are related to the amount of bone ingrowth on porous surface of the stem. Thus, a model developed for this interface ...

A 64-year-old diabetic lady underwent pars plana vitrectomy in her left eye for a taut posterior hyaloid face due to proliferative diabetic retinopathy (PDR). Visual acuity (VA) at baseline had been 20/120. She had previously received panretinal laser photocoagulation (PRP) and the retinopathy had been stable, but there was localized extrafoveal tractional retinal detachment in the inferonasal ...

Congenital fibrovascular pupillary membrane (1-4) is an unilateral ocular change of the anterior segment (Figure 1). This abnormality was first reported by Cibis et al. in 1986. In some cases, progressive miosis, posterior embryotoxon and abnormality of the anterior chamber angle have been documented. Pupillary membrane might not be adhered to crystalline, or it can also be associated with ante...

The bone ingrowth potential of biomimetic hydroxyapatite and brushite coatings applied on porous E-beam structure was examined in goats and compared to a similar uncoated porous structure and a conventional titanium plasma spray coating. Specimens were implanted in the iliac crest of goats for a period of 3 (4 goats) or 15 weeks (8 goats). Mechanical implant fixation generated by bone ingrowth ...

We describe a case of a giant fibrovascular polyp arising from the oropharynx and causing vague clinical symptoms. To our knowledge, this is the first description of an oropharyngeal fibrovascular polyp reported in the medical literature. The diagnosis was based on MR imaging findings, which showed the size and configuration of the polyp as well as the site of attachment. The patient underwent ...

INTRODUCTION We present a case of fibrovascular polyp, a rare submucosal tumour of the oesophagus that has been reported only sporadically in the literature. The biapproach for surgical removal of fibrovascular polyp has only been mentioned once in the literature. CASE PRESENTATION A 65-year-old Greek man presented with a 9-month history of gradually progressive intermittent dysphagia. Radiol...

BACKGROUND To evaluate the short-term efficacy of intravitreal injections of aflibercept (IVA) to treat retinal angiomatous proliferation (RAP) and identify factors related to functional outcomes. METHODS This retrospective case series consisted of 19 eyes in 19 patients with RAP. All 19 eyes received 3 monthly consecutive IVA. The primary outcome measures were best-corrected visual acuity (B...
