1/7. Endoscopic basket extraction of a urethral foreign body.The presence of a foreign body in the genitourinary tract represents a urologic challenge that often requires prompt intervention. We describe an endoscopic approach that was used for removal of a foreign body located in the prostatic urethra of a schizophrenic man. A nitinol stone basket was used as an effective means for extraction of a large metal screw from the urethra of this patient.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/7. Gradual extrusion of implant: an unusual complication after intraocular lens implantation.A 65-year-old woman had undergone cataract extraction with implantation of an intraocular lens (IOL) in the left eye 5 years previously. The eye remained irritated and she did not regain useful vision. She had pain and foreign body sensation in that eye for 3 months that became especially severe in the 3 days prior to presentation. On examination, the optic and one haptic of an IOL protruded through a small fistula in a leukomatous cornea. The tip of the other haptic was embedded in the fistula. The surgical scar was intact and there was a circular depression on the superior cornea identical in size and shape to the optic. There was no history of trauma or rheumatoid arthritis. The IOL, barring one haptic, may have extruded through the site of a perforated corneal ulcer and remained impacted on the corneal surface, allowing healing under it. This is an extremely unusual presentation of an extruded IOL.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
3/7. Chronic inflammation and pain inside the mandibular jaw and a 10-year forgotten amalgam filling in an alveolar cavity of an extracted molar tooth.A 55-year-old woman, suffered from severe pain in her mandibular jaw for several years. A metallic artifact of about 2(3) mm was detected by a panorama radiography in an edentulous region with a surrounding inflammation in close contact to the canal of the mandibular nerve. Inflammated tissue with the central metallic inclusion was removed from the bone under local anesthesia and operation. Postoperatively, pain and missensitivity disappeared within 1 week. Although the patient had no macroscopically visible so-called amalgam tattoo, the metallic cube was identified as amalgam by the detection of mercury, silver, tin, copper, and zinc using energy dispersive X-ray analysis (EDX) in a scanning electron microscope (SEM). Nevertheless, brown to black pigments in the connective tissue matrix and inside histiocytes, fibroblasts, and multinucleated foreign giant cells of the surrounding inflammatory tissue were observed by light and electron microscopy. However, the elemental analysis by EDX in SEM or by electron energy loss spectroscopy in transmission electron microscope detected only silver, tin, and sulfur but no mercury in these precipitates and in the residual bodies of phagocytes. The presented case demonstrates a seldom complication of amalgam deposition in the tissue. The authors assume that the chronic pain results from a forgotten amalgam filling inside an alveole after extraction of a molar tooth, causing a chronic inflammation by resolving mercury and other toxic elements out of the metallic artifact.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
4/7. Myospherulosis. Report of a case.A case of myospherulosis, a condition first reported in 1969, is reported following the extraction of mandibular third molars and subsequent placement of Terra-Cortril and Gelfoam into the extraction sites. The lesions were discovered during a periodontal surgical procedure and to the best of our knowledge this is the first such report in the periodontal literature.- - - - - - - - - - ranking = 0.4keywords = extraction (Clic here for more details about this article) |
5/7. Long-term corneal retention of a plant foreign body.A fragment of sunflower stalk had been retained in the cornea of a 71-year-old man for 58 years. During initial healing of the wound, which included formation of a retrocorneal membrane over the foreign body in the anterior chamber, there was probably loss of endothelial cells. This probably predisposed the cornea to the endothelial decompensation that occurred following cataract extraction and implant of an intraocular lens 56 years after the foreign body first appeared in the cornea.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
6/7. Pseudophaco--anaphylactic endophthalmitis? P.M.M.A. related.The pathological findings of pseudophacoanaphylactic endophthalmitis are described in a patient with a combined trabeculectomy, extracapsular cataract extraction and an "in-the-bag" posterior chamber lens implant, and who developed sympathetic ophthalmitis following a perforating eye injury within hours of his operation. Apart from the typical sympathetic histological findings, the eye revealed a pseudophaco-anaphylactic endophthalmitis reaction which appeared to be totally related to the polymethylmethacrylate (P.M.M.A.) optic. The "in-the-bag" polypropylene closed loops revealed no significant histological reaction.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
7/7. Scanning electron microscopic study of an anterior chamber intraocular lens: latent endophthalmitis.Two years after intracapsular cataract extraction and intraocular lens implantation, an anterior chamber lens was removed. The lens was studied by scanning electron microscope which demonstrated the presence of colonies of cocci, a thin acellular membrane covering part of the lens and some modifications of the lens surface.- - - - - - - - - - ranking = 0.2keywords = extraction (Clic here for more details about this article) |
