Foreign body reaction induced by biomaterials is a serious problem in clinical applications. Although 317L-Cu stainless steel (317L-Cu SS) is a new type of implant material with antibacterial ability and osteogenic property, the foreign body reaction level still needs to be assessed due to its Cu(2+) releasing property. For this purpose, two macrophage cell lines were selected to detect cellula...

Case description- A 6 month old common mynah (Acridotheres tristis) of unknown sex, weighing 200 g, was referred to Veterinary Teaching Hospital of Ferdowsi University. The mynah had history of swallowing a foreign body for one day. Clinical findings- Circular-like radiopaque foreign body was seen from thoracic inlet to distal end of the celomic cavity in the lateral and ventrodorsal radiograph...

RATIONALE Resorbable materials have been recommended for orbital fractures repair. Many literatures reported the advantages of resorbable materials in clinical applications, but few reports about complications. PATIENT CONCERNS In this study, we encountered a 14-year-old boy treated for the orbital fracture by using resorbable plate, in whom inflammatory foreign body reaction was detected. In...

introduction: determination of type and location of trapped objects and endoscopic observations among children with foreign-body ingestion. materials and methods: we evaluated 105 endoscopic records of patients presenting with foreign-body ingestion from 2001–2011. results: button batteries were the most common objects removed (41%). the lower segment of the esophagus was the most common trappi...

Most materials used clinically for filling critical-sized bone defects (CSBD), such as deproteinized bovine bone (DBB), lack osteoinductivity so that their therapeutic effects are far from satisfactory. The effect of bone morphogenic protein 2 (BMP2)-coprecipitated biomimetic calcium phosphate granules (BMP2-cop.BioCaP) on osteoinduction of DBB graft(s) during CSBD healing is still unknown. We ...

of absorbable gelatine sponge (AGS), and to find out if AGS combined with corticosteroids and/or antibiotics have an influence on these changes. Study design: Animal study Materials and Methods: Thirty-two adult guinea pigs were divided into four groups, with eight ears in each group. In control group, nothing was inserted to middle ear after traumatization of mucosa (group A). In study groups,...

BACKGROUND Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. METHODS A total of 234 patients with a maxillofacial fr...

introduction foreign body aspiration is common especially in children. the absence of history of choking does not rule out the diagnosis. diagnosis required high index of suspicion. case presentation undiagnosed foreign body aspiration mostly occurs in bronchial airway rather than larynx and can cause severe complications. in this article, we report a silent laryngeal foreign body aspiration to...

Introduction The well known habit of children to place objects in mouth frequently leads to impaction of foreign body in tracheobronchial tree. It is one of the leading causes of accidental home deaths in children under 6 years. (1) The major issue involves the accurate diagnosis, speedy and safe retrieval of the foreign body. The accurate diagnosis may elude even the sophisticated physician be...

Gossypiboma, an infrequent surgical complication, is a mass lesion due to a retained surgical sponge surrounded by foreign body reaction. In this case report, we describe gossypiboma in the abdominal cavity which was detected 14 months after the hysterectomy due to acute abdominal pain. Gossypiboma was diagnosed by computed tomography (CT). The CT findings were a rounded mass with a dense centr...
