1/7. Early acute aseptic iritis after cataract extraction.Severe iritis which occurs within the first five days after cataract extraction may be categorized as (1) bacterial endophthalmitis, (2) toxic iritis, or (3) aseptic iritis. These entities can sometimes be distinguished because of their clinical features. If bacterial endophthalmitis is suspected, anterior chamber paracentesis should be considered and appropriate antibiotic treatment should be initiated. Acute iritis may result from the introduction of toxic agents into the eye, and may follow the use of products sterilized with ethylene oxide. Early acute aseptic iritis probably occurs more often than has previously been recognized. Response to intensive anti-inflammatory treatment is usually prompt and dramatic. The judicious use of cryoextraction and the careful manipulation of intraocular tissues may minimize the incidence and the severity of postoperative inflammation.- - - - - - - - - - ranking = 1keywords = extraction (Clic here for more details about this article) |
2/7. Ophthalmomyiasis in a child.A 4-year-old child presented with a 3-week history of left eye swelling. The periorbital inflammation was a result of a larva of the human botfly, Dermatobia hominis. Surgical extraction of the larva was curative.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
3/7. Xanthogranulomatous choledochitis: a previously undescribed mass lesion of the hepatobiliary and ampullary region.Solid liver and pancreatic masses are commonly neoplastic in nature; however, inflammatory lesions mimicking carcinoma are at times encountered in these sites. We report two cases of previously undescribed inflammatory mass lesions of the liver and pancreas that originated in the biliary tract. Detailed clinical and histologic evaluations were performed in two patients who underwent right partial hepatic lobectomy and Whipple's resection for presumed hepatic and pancreatic neoplasms. In case 1, with a remote history of cholecystectomy and recent extraction of a stone from the common bile duct, a liver mass in segment 6 was discovered incidentally. In case 2, a periampullary pancreatic mass was diagnosed radiographically following papillotomy and stent insertion for stricture and biliary calculous disease. The histologic findings in both cases were similar, localized around a part of the biliary tract, and consisted of inspissated bile, acute and chronic inflammation, abundant lipid-laden macrophages, fibrosis, and giant cell reaction. No neoplasm was identified. On the basis of the close resemblance of these features to those seen in xanthogranulomatous cholecystitis, the lesions seen here were termed xanthogranulomatous choledochitis. In conclusion, xanthogranulomatous choledochitis is a benign inflammatory process involving the biliary tract that can form a mass lesion within the liver or pancreas and thus mimic a neoplasm. Extensive sampling of the lesion is required to rule out an underlying neoplastic process. In our patients a propensity to form lithogenic bile and a prior history of biliary tract operative procedure were present.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
4/7. Early loading of interforaminal implants immediately installed after extraction of teeth presenting endodontic and periodontal lesions.BACKGROUND: infection in tooth extraction sites has traditionally been considered an indication to postpone implant insertion until the infection has been resolved. PURPOSE: The aim of this study was to evaluate the survival rate of early-loaded implants placed immediately after extraction of teeth with endodontic and periodontal lesions in the mandible. MATERIALS AND methods: Twenty patients in need of mandibular implant treatment and with teeth showing signs of infection in the interforaminal area were included in the study. The patients received four to six implants (Branemark System, Nobel Biocare AB, Goteborg, sweden) in or close to the fresh extraction sockets and received a provisional prosthesis within 3 days. Final prostheses were delivered after 3 to 12 months. The surgical protocol paid special attention to the preservation of high implant stability and control of the inflammatory response. The patients were followed up for 15 to 44 months. RESULTS: No implants were lost, resulting in a 100% survival rate. A mean marginal bone loss of 0.7 mm (SD 1.2 mm) was registered during the observation period. No signs of infection around the implants were detected at any follow-up visit. CONCLUSION: A high survival rate can be achieved for immediately placed and early-loaded implants in the mandible despite the presence of infection at the extracted teeth.- - - - - - - - - - ranking = 1.1666666666667keywords = extraction (Clic here for more details about this article) |
5/7. Intralesional immune therapy: methanol extraction residue of BCG or purified protein derivative.6 patients with cutaneous malignant melanoma and multiple secondary cutaneous lesions were treated with intralesional methanol extraction residue of bacillus Calmette Guerin (MER-BCG). Separate lesions were injected with purified protein derivatives (PPD) in 5 of the study patients. 5 of the 6 MER-BCG injection lesions developed marked inflammation clinically. Excisional biopsy 7-14 days later demonstrated complete dissolution of tumor in 2 patients and was accompanied by infiltration with acute and chronic inflammatory cells; 3 lesions revealed necrosis with residual tumor, and in 1 patient there was no apparent host response. Clinical tumor regression was not observed with PPD applied intralesionally, although histopathologic analysis revealed a granulomatous inflammatory response in 3 of 5 patients. No patient demonstrated regression of uninjected cutaneous lesions (4 evaluable patients) or visceral lesions (2 patients). The critical determinants of tumor regression are the size, site and depth of the lesion in relationship to the cutaneous surface. The mechanism of tumor eradication may be related to 'innocent bystander' necrosis secondary to nonspecific inflammation rather than immunologically mediated via host sensitization.- - - - - - - - - - ranking = 0.83333333333333keywords = extraction (Clic here for more details about this article) |
6/7. Long-term changes in corneal endothelium following intraocular lens implantation.To understand the long-term effects of intraocular lens implantation on corneal endothelium, 52 eyes with intraocular lens implantations and 35 eyes with simple cataract extractions were studied using clinical specular microscopy. Endothelial photographs were obtained preoperatively and at least four times in the postoperative period in each case. The postoperative period ranged from 16 to 43 months. Our observations demonstrated that intraocular implants produce a greater magnitude of endothelial cell damage and iris-supported lenses have a more deleterious effect on the corneal endothelium compared with anterior chamber lenses. Seventy-one percent of the eyes with intraocular implants demonstrated precipitates on the endothelium with 16% developing guttata-like areas. All these changes were progressive with time with no such phenomenon occurring in eyes with simple cataract extractions. The progressive endothelial cell damage may be a sequel of chronic, smoldering uveitis associated with intraocular implants.- - - - - - - - - - ranking = 0.33333333333333keywords = extraction (Clic here for more details about this article) |
7/7. Peripheral corneal ulcers, conjunctival ulcers, and scleritis after cataract surgery.After undergoing uneventful cataract extractions, four patients developed an inflammatory reaction that included scleritis and peripheral corneal infiltrates and ulcers. Two of these patients also developed conjunctival ulcers. The inflammatory reaction in all four patients responded to topical corticosteroids.- - - - - - - - - - ranking = 0.16666666666667keywords = extraction (Clic here for more details about this article) |
