1/97. Nonradiopaque penetrating foreign body: "a sticky situation".foreign bodies within soft tissues are common in children. They may cause a chronic inflammatory reaction that can result in abnormal findings on radiographs, including lytic or blastic osseous changes. These radiographic findings can mimic both benign and malignant processes. In cases where the history is uncertain and the foreign body is not recognized, magnetic resonance (MR) imaging can make a specific diagnosis and direct appropriate therapy.- - - - - - - - - - ranking = 1keywords = reaction (Clic here for more details about this article) |
2/97. Complete dentures and the associated soft tissues.Some of the conditions of the soft tissues related to complete dentures encountered during a period of 25 years at a university clinic were presented and discussed from the standpoint of the clinical prosthodontist. During this time, over 1,000 denture patients were treated each year. For some conditions, a method of management was offered with treatment by sound prosthodontic principles rather than unneccessary medication. That denture fabrication involves much more than mere mechanical procedures is an understatement. Complete dentures are foreign objects in the oral cavity that are accepted and tolerated by the tissue to a degree that is surprising. As prosthodontists, we can gain satisfaction from the realization that the incidence of oral cancer due to dentures is less than extremely low. At the same time, we must be ever mindful of the statement by Sheppard and associates. "Complete dentures are not the innocuous devices we often think they are." Every dentist must remember that one of his greatest missions is to serve as a detection agency for cancer. The information discussed indicates (1) the need for careful examination of the mouth, (2) the value of a rest period of 8 hours every day for the supporting tissues, and (3) the importance of regular recall visits for denture patients. Robinson stated that while the dental laboratory technician can be trained to aid the dentist in the fabrication of prosthetic devices, his lack of knowledge of reactions and diseases of the oral tissues limits him to an auxiliary role. Complete prosthodontics is a highly specialized health service that greatly affects the health, welfare, and well-being of the patient. It can be rendered only by the true professional who is educated in the biomedical sciences.- - - - - - - - - - ranking = 1keywords = reaction (Clic here for more details about this article) |
3/97. Sonographic appearance of a retained surgical sponge in the neck.We report the sonographic appearance and clinical course of a retained surgical sponge in the neck beginning 6 months after a partial thyroidectomy. Sonograms showed a subcutaneous curvilinear hyperechoic interface with marked acoustic shadowing obscuring the left side of the neck. Three months later, a fistulous tract could be seen. Surgical exploration revealed a florid foreign tissue reaction due to a retained surgical sponge. early diagnosis of retained sponges is important to enable expeditious removal before complications develop.- - - - - - - - - - ranking = 1keywords = reaction (Clic here for more details about this article) |
4/97. Patient tolerance of cervical esophageal metallic stents.PURPOSE: To demonstrate that proximal esophageal stenoses and tracheoesophageal fistulas can be adequately palliated with use of metallic stents without significant foreign-body sensation. MATERIALS AND methods: Between June 1994 and March 1999, 22 patients with lesions within 3 cm of the cricopharyngeus were treated by placement of metallic stents. The series was reviewed retrospectively. Twenty patients had surgically unresectable malignant lesions, two patients had benign disease. Ten patients had associated tracheoesophageal fistulas. In all, the upper limit of the stent was between C5 vertebral body inferior endplate and the T2 vertebral body superior endplate. The case-notes were reviewed until patient death (range, 6-198 days), or to date in the two surviving patients with benign disease. RESULTS: Immediate technical success was 93% (27 of 29). Dysphagia scores improved from a median of 3 to 2 after stent placement. Eighteen of 22 (82%) patients reported no foreign-body sensation. There have been no cases of proximal migration, periprocedural perforation, or deaths. The two patients with benign disease experienced significant complications. CONCLUSION: Lesions in proximity to the cricopharyngeus can be successfully palliated without significant foreign-body sensation in the majority of patients with use of metallic stents. The authors urge caution in placing stents in patients with benign disease.- - - - - - - - - - ranking = 70875.221557526keywords = foreign-body (Clic here for more details about this article) |
5/97. aspergillosis of the maxillary sinus as a complication of overfilling root canal material into the sinus: report of two cases.aspergillosis of the maxillary sinus is a relatively rare disease in nonimmunocompromised patients. In recent years a number of cases of aspergillosis of the maxillary sinus have been reported in association with overextension of root canals fillings with certain root canal cements. It has been suggested that zinc oxide-based root canal cements might promote the infection with the Aspergillus species. In particular aspergillus fumigatus has been found to be associated with the maxillary sinus infection. Radiographically the unique appearance of a dense opacity foreign body reaction in the maxillary sinus was considered a characteristic finding in maxillary sinus aspergillosis. Because this association of overfilling of root canal cements and aspergillosis of the maxillary sinus is not too well known we report two cases of young healthy female patients with the characteristic findings, both radiographically and clinically. In both patients the first maxillary molar was involved. patients were symptomless and the diagnosis was made accidently. However at surgical inspection both patients revealed aspergillomas, including the overextended root canal cement. The surgical procedure is described as are the microscopic findings in both cases showing the characteristic branching hyphae and conidophores typical of Aspergillus. Overextension into the maxillary sinus with root canal cements has to be avoided; material has to be removed from the sinus because otherwise aspergillosis infection may ensue.- - - - - - - - - - ranking = 1keywords = reaction (Clic here for more details about this article) |
6/97. A metal ring that had been lodged in a child's nasopharynx for 4 years.A considerable number of articles on foreign-body ingestion and inhalation have been reported in the literature. Of these, nasopharyngeal foreign bodies are rare. Unless they cause total obstruction, symptoms typically appear late. foreign bodies, especially metal ones, can lodge in soft tissue, and their removal can be rather complicated. In this article, we describe the case of a 4-year-old girl who had had a gold ring lodged in her nasopharynx. The history led us to determine that the ring had been there since the child was 3 months old. A flexible fiberoptic nasopharyngeal examination revealed that the ring was embedded in the nasal surface of the soft palate and was enclosed by a thin layer of mucosal membrane. With the patient under general anesthesia, we were able to remove the foreign body with a 0 degree endoscope.- - - - - - - - - - ranking = 23625.073852509keywords = foreign-body (Clic here for more details about this article) |
7/97. An unusual swelling following endodontic and prosthodontic treatment of a mandibular molar due to a foreign body reaction.AIM: The purpose of this case report is to stress the importance of taking a proper history and the appropriate evaluation of diagnostic tests in order to prevent incorrect diagnosis and treatment. Moreover, the management of postoperative problems in a healthcare system in which specialists take on specific parts of the treatment is discussed. SUMMARY: This article describes the diagnosis and treatment of an unsuspected flare-up 1 week after root canal treatment. The swelling and pain appeared to be associated with an accidentally embedded piece of impression material. general practitioners and specialists should be aware of alternate treatment plans and treatment procedures and take these into consideration whenever there is a postoperative problem to be solved. KEY learning POINTS: Impression materials can cause a foreign body reaction when embedded in the soft tissues. history taking and evaluation of diagnostic tests are of paramount importance in order to prevent incorrect diagnosis and treatment. Both general practitioners and specialists have the responsibility to evaluate patients with a broad vision.- - - - - - - - - - ranking = 5keywords = reaction (Clic here for more details about this article) |
8/97. Aspirated foreign body in a laryngectomized patient: case report and literature review.The presence of a permanent tracheal stoma in a laryngectomized adult is a predisposing factor for foreign-body aspiration, as are conditions that impair normal protective airway mechanisms. Such an aspiration can cause significant morbidity if it is not properly managed. The use of rigid bronchoscopy to remove an aspirated object can be difficult in these patients, and a high percentage of them require thoracotomy, especially for the removal of sharp objects. An emphasis on patient education regarding the handling of objects around the stoma in laryngectomized adults is key to preventing aspiration and its complications.- - - - - - - - - - ranking = 23625.073852509keywords = foreign-body (Clic here for more details about this article) |
9/97. Chronic paronychia in which hair was a foreign body.A patient who worked as a baker and a part-time barber had chronic paronychia. biopsy revealed the presence of hair in the dermis of the nail fold. This is only the second case of chronic paronychia to be reported in which the dermis contained nonmicrobial exogenous material. Based on experimental work it has been previously suggested that the rounding out of the posterior nail fold in most paronychia is due to the body's reaction to the penetration of debris derived from candida albicans. However, patients recalcitrant to therapy or those exposed to chemicals or particulate material deserve detailed histologic study.- - - - - - - - - - ranking = 1keywords = reaction (Clic here for more details about this article) |
10/97. Removal of a mis-swallowed long spoon via gastrotomy--a case report.Foreign body ingestions are a frequent occurrence, a common presentation at emergency departments, but long, pointed-end metallic spoon swallowing is an uncommon occurrence. Unlike most cases of foreign-body ingestion, there have been no cases of spontaneous passage reported. Consequently, prompt removal is recommended before complications develop. We report a case of accidental ingestion of a long, pointed metallic spoon which failed to pass through the gastrointestinal tract and be excreted. This patient was managed successfully with gastrotomy to remove the object. We recommend this approach for the removal of long pointed foreign bodies to avoid complications developing.- - - - - - - - - - ranking = 23625.073852509keywords = foreign-body (Clic here for more details about this article) |
