This report describes an unusual nasal foreign body in a 4-year-old boy discovered incidentally in a routine dental radiograph. A small piece of rubber eraser was lodged in the right nasal cavity, causing unilateral nasal obstruction and discharge, sneezing, snoring and breathing difficulty. In this case, discovery of unknown intranasal object was diagnostic for a condition suspected of pathological origin. Dentists may play a significant role in the diagnosis of intranasal foreign objects in children, through careful clinical examination and interpretation of dental radiographs. Early diagnosis is emphasized in order to avoid complications.  相似文献

Five commonly used types of orthodontic plier of similar design, but different manufacture were evaluated for wear and corrosion following a 6-month regime of routine use in a hospital department together with steam autoclaving in a centralized unit. Three different types of manufacture (metal finish) were evaluated: (1) a stainless steel plier; (2) a chrome plated plier; and (3) a cheaper chrome plated plier. Four identical kits for changing archwires were assembled for each of the three manufacture types. A sixth 'plier', always of chrome plated manufacture (group 2) was added to every kit and acted as an additional control. In all, 72 pliers were evaluated by three observers immediately before and after the trial. Visual analogue and rank scales were used to assess corrosion, damage, the efficiency of the plier, etc. Generally, all of the pliers stood up well to a combination of routine clinical use and steam autoclaving; however, the stainless steel pliers appeared to perform the best. It is likely that the most important factor, when setting up this type of sterilizing method for orthodontic instruments, is to establish a careful and meticulous routine for cleaning, lubricating, and steam autoclaving pliers.  相似文献

A 27-year-old male presented with intracranial embolization due to accidental penetration of his neck by an iron fragment at work. Cerebral angiography revealed foreign body embolization of the left middle cerebral artery. The foreign body was successfully removed via craniotomy and arteriotomy. The extended period from onset to surgical treatment prevented acute hemodynamic reconstruction. However, he had good collateral circulation and was discharged with mild hemiparesis and moderate motor aphasia. The possibility of intracranial embolization should be considered in patients presenting with penetrating injury of the neck.  相似文献

A case of the foreign body due to coring from the rubbercap of a 50 ml Diprivan vial was reported. Furthermore, how the fragment is made and how to decrease the incidence are discussed. The incidence of coring should decrease by improvement of the needle and by sticking vials vertically. However, even if the improvement of the rubber, needles and sticking technique is achieved, the occurrence of coring can not be eliminated completely. The best way to avoid coring will be to furnish "50 ml syringes containing Diprivan" commercially.  相似文献

OBJECTIVES: The object of our study was a long-time presence of a foreign body in an episiotomy scar. STUDY DESIGN: A case of 46-year old woman with a palpable tumour in a perineal region is described. RESULTS: This false tumour was caused by a surgical needle which was left in the body of the patient 19 years ago during the episiorrhaphy after the last labour. CONCLUSION: Because of a character and localisation of the change the method of choice was surgical treatment which completely eliminated all symptoms.  相似文献

PURPOSE: Ocular missile injuries often involve the lens. Some have suggested that lens capsular violation by a foreign body is an indication for immediate lens removal. Sometimes, however, the resultant lens opacity may remain localized without visual compromise. The authors report a series of patients who had lens capsular disruption from an intraocular foreign body that resulted in visually insignificant lens opacities. METHODS: A series of five patients with lens capsular disruption as a result of an intraocular foreign body injury were reviewed retrospectively. RESULTS: All five patients had lens injury from a small foreign body in a peripheral lenticular location. In three patients the foreign body was intralenticular, whereas in the other two patients the foreign body transversed the lens and was located in the posterior segment. In two patients, the foreign body was not removed. Three of the patients required pars plana vitrectomy. In all patients, final visual acuity was at least 20/40, and the lenticular opacity remained localized to an eccentric location. CONCLUSIONS: A progressive, visually significant cataract is not the inevitable result of lens injury by an intraocular foreign body. When indicated, surgical removal of the foreign body may be attempted using a lens-sparing procedure.  相似文献

The AA. report the case of a 79 years-old patient suffering an esophageal stenosis managed with intubation (Celestin's tube). This instance shows the good tolerance of the prosthesis by the patient as well as the undue of its stay. And by the way, the simplicity of its removal with a rigid esophagoscope, as was the present case. The paper contemplates a brief review of the indications for esophageal intubation and possible complications when dealing with organic stenosis of the esophagus.  相似文献

PURPOSE: To present an ultrasonographic finding that simulated an intraocular foreign body after repair of a ruptured globe. METHOD: Case report. An ultrasonogram of a post-trauma eye was correlated with a computed tomographic scan. RESULTS: B-scan ultrasonography was performed on an eye after repair of a corneoscleral laceration. The ultrasonogram showed a highly reflective echo source suggestive of a foreign body; however, an orbital computed tomographic scan demonstrated that the lesion was intraorbital air. CONCLUSION: Although a highly reflective echo source in the presence of a ruptured globe may suggest a foreign body, the presence of orbital air should also be considered when interpreting ultrasonograms used in the preoperative and postoperative management of globe trauma.  相似文献

PURPOSE: To examine the effect of mixing techniques (hand-mixing vs. trituration) on fluoride release from chemically-cured (Fuji II) and resin-modified (Fuji II LC) glass ionomer products. MATERIALS AND METHODS: Fluoride measurements were determined and comparisons made between hand-mixed-type materials that were both hand-mixed (60 seconds) and triturated (10 seconds). Hand-mixed specimens were made using the manufacturer's recommended powder/liquid ratio. Triturated specimens of the same material were made using the same powder/liquid ratio. Disk specimens (8.5 mm diameter, 2 mm thickness; n = 6) were stored in deionized water for 23 hours to obtain Day 1 solutions. Solutions were also obtained at 2, 3, 4, 5, 6, 7, 14, 21, and 28 days after fabrication and were changed 24 hours before fluoride concentration was determined using a fluoride ion selective electrode. Daily rates of fluoride release and 28-day cumulative fluoride totals were calculated. Cumulative data were analyzed by two-way ANOVA and Scheffé's test (alpha = 0.05). Daily results were analyzed by the Mann-Whitney U-test. RESULTS: A significant difference was observed between materials (P < 0.001). Depending on the kind of material used, the method of manipulation affected the fluoride release. Data analysis revealed that: (1) Fuji II LC released significantly more fluoride than Fuji II for both triturated (P = 0.005) and hand-mixed (P < 0.005); (2) the triturated Fuji II released significantly more fluoride than the hand-mixed (P = 0.02); and (3) the hand-mixed Fuji II LC released more fluoride than the triturated, but was not statistically significant (P = 0.16).  相似文献

AIMS: To visualise directly numerical chromosomal aberrations and polyploidy in both Hodgkin and Reed Sternberg (HRS) cells and background cells from cases of Hodgkin's disease using in situ hybridisation. METHODS: Non-isotopic DNA in situ hybridisation was applied to interphase cell nuclei of Hodgkin's disease within routine paraffin embedded tissue sections. Two a satellite DNA probes, specific for chromosomes 3 and 12, were used to evaluate the feasibility of this approach. Double labelling with immunocytochemical detection of the CD30 antigen was used to identify HRS cells. Cytogenetic normal diploid and triploid placental tissue served as controls. RESULTS: The eight cases of Hodgkin's disease investigated displayed frequent polysomy, while the majority of background cells showed disomy signals. CONCLUSIONS: Numerical chromosomal aberrations were detected in HRS cells from eight cases of Hodgkin's disease by in situ hybridisation. These data show that in Hodgkin's disease HRS cells frequently display polyploidy compared with background cells and are, therefore, probably the only neoplastic component in this disease. Correlations between polysomy and tumour type or grade could not be made from these data owing to the limited number of cases examined and to problems with interpreting data from truncated nuclei.  相似文献

According to the research that there were some immune and inflammatory substances in the synovial fluid of temporomandibular joint disturbance syndrome (TMJDS), we improved the traditional intraarticular injection and developed an intraarticular irrigation-injection therapy to treat 43 cases of TMJDS and got a good result. The controls include two groups, the simple rinsing and the traditional injection. Statistical analysis showed a highly significant difference in the effects between test and control groups. In order to study the mechanism of the therapy, the tumor necrosis factor (TNF) in synovial fluid of 8 cases were assessed. It was found that the concentration of TNF was reduced markedly after treatment. We think that the new therapy is effectable for TMJDS and could be used widely.  相似文献

Many different lesions can be difficult to distinguish from malignant melanomas of the choroid. With the use of modern diagnostic facilities the misdiagnosis rate has been greatly reduced. In a recent report from the Collaborative Ocular Melanoma Study Group the incidence of misdiagnosis was only 0.48%. The presence of a retained intraocular foreign body presenting as a raised pigmented choroidal mass similar to a uveal melanoma is rare. We report two cases in which retained intraocular foreign bodies presented clinically as raised pigmented intraocular lesions. Retained intraocular foreign bodies should be considered in the differential diagnosis of ocular tumours, especially if there are any atypical features.  相似文献
