[Statistical study on the case of aural foreign bodies].

Although aural foreign bodies are very frequently seen in daily practice, few reports systematically analyze a large case population. We report 509 cases seen at our clinic during the 16 years from January 1986 to December 2001. All were clinically confirmed during the same period among a total of 68,579 new visitors and cases with aural foreign bodies accounted for 0.74%. Cases seen during routine outpatient clinic hours were 161 (31.6%), and others seen in emergencies were 348 (68.4%). Among these were 307 men (60.3%) and 202 women (39.7%). The right side involved 251 (49.3%), the left side 241 (47.3%), and bilateral 4 (0.8%). Monthly distribution showed an average of 42.4 cases a month, peaking during the months of July and August, when temperatures are highest. Age distribution showed an average of 25.4 years old, ranging from 1 month to 90 years of age. Those under 9 years numbered 182 (35.8%) and were the peak incidence by age. In classification by organic and inorganic, organic materials accounted for 206 (40.5%) and inorganic for 288 (56.6%). Organic materials appeared to be related to monthly distribution, i.e. more cases in hot months.

Tracheo-bronchial foreign bodies.

Suspicion of foreign bodies inhalation is a frequent problem in clinical practice. Despite the fact that the parents or the patients themselves easily notice symptoms, the delay in initiating diagnostic procedures is important. Delaying diagnosis and extraction results in potential severe complications. Diagnosis and treatment rely on invasive bronchoscopic procedures and therefore a careful designed standardized evaluation should be employed in order to decrease unnecessary bronchoscopies. Classical clinical signs of foreign body inhalation have low positive predictive values and every attempt to confirm or exclude the diagnosis should be done. Patients should be addressed to experienced centers for evaluation and treatment. Confirmation of the diagnosis should be done by flexible bronchoscopy. Extraction generally relies on rigid bronchoscopy, which seems to be more secured. Flexible bronchoscopy can also be used for extraction but rigid bronchoscopy should be always immediately available. Extraction failure rate and complications are rare in hands of experienced individuals and surgical removal is seldom necessary.

Localization and removal of ferromagnetic foreign bodies by magnet.

Foreign bodies should be removed from wounds during the primary wound management stage whenever possible. Metallic fragments can be identified and localized by conventional radiography, computed tomography, sonography, x-ray image intensifier, or electromagnetic metal detector. Locating metallic objects may still cause problems for the surgeon during the removal procedure. Detection and removal of superficial ferromagnetic fragments (iron, nickel, and cobalt) by a magnet is possible. In the literature the authors found no report about using the magnet for this purpose. Having conferred with the manufacturer KANAT (Istanbul, Turkey), the authors used a magnet made of neodymium. The power of the magnet was 12,000 gauss. It was cylindrical and 1.3 x 0.8 cm in diameter. This method was used in 6 patients successfully for localization and removal of ferromagnetic foreign bodies. Use of a magnet is an easy and cost-effective method that does not require education and specific staff.

Inhibition of methylcholanthrene-induced carcinogenesis by an interferon gamma receptor-dependent foreign body reaction.

The foreign body reaction is one of the oldest host defense mechanisms against tissue damage which involves inflammation, scarring, and encapsulation. The chemical carcinogen methylcholanthrene (MCA) induces fibrosarcoma and tissue damage in parallel at the injection site. Tumor development induced by MCA but not due to p53-deficiency is increased in interferon-gamma receptor (IFN-gammaR)-deficient mice. In the absence of IFN-gammaR, MCA diffusion and DNA damage of surrounding cells is increased. Locally produced IFN-gamma induces the formation of a fibrotic capsule. Encapsulated MCA can persist virtually life-long in mice without inducing tumors. Together, the foreign body reaction against MCA prevents malignant transformation, probably by reducing DNA damage. This mechanism is more efficient in the presence of IFN-gammaR. Our results indicates that inflammation and scarring, both suspected to contribute to malignancy, prevent cancer in certain situations.

Evaluation of clinical, radiologic, and laboratory prebronchoscopy findings in children with suspected foreign body aspiration.

BACKGROUND: Foreign body aspiration (FBA) in infants and young children is a common and potentially life-threatening event. Although studies have extensively described the signs and symptoms of suspected FBA (sFBA), only few systematically compared their value for predicting bronchoscopy results. OBJECTIVES: The objectives of this study were to describe the clinical and radiologic signs and symptoms of sFBA and to identify predictors of bronchoscopically proven FBA (pFBA). SETTING: This study was conducted at a referral tertiary university hospital with an outpatient clinic and a 90-bed pediatric unit. METHODS: Signs and symptoms were retrospectively analyzed for all children who had received bronchoscopy between July 1992 and April 2000 because of sFBA. Radiologic signs of FBA were reviewed and scored by 2 independent radiologists. RESULTS: One hundred sixty children (mean age, 2.8 years; range, 11 months to 16.8 years) were enrolled in the study. Foreign body aspiration, mostly affecting the right main bronchus, was proven bronchoscopically in 122 (76%) of these children. Independent predictors of pFBA in multivariable analyses were focal hyperinflation on chest radiograph (beta = 45.4; 95% confidence interval [CI] = 5.3-390.5; P = .001), witnessed choking crisis (beta = 18.6; 95% CI = 4.7-73.0; P < .001), and white blood cell count greater than 10,000/muL (beta = 4.2; 95% CI = 1.2-14.7; P = .026). The cumulative proportion of pFBA cases increased with the number of risk factors (0, 16%; 1, 47%; 2, 96%; 3, 100%). CONCLUSIONS: Clinical judgment to perform bronchoscopy for sFBA was correct in 76% of the children investigated. Focal hyperinflation, witnessed choking crisis, and elevated white blood cell count were strongly associated with pFBA; bronchoscopy can be strongly recommended in the presence of at least 2 risk factors when FBA is suspected.

Intralenticular metal foreign body: case report.

Intralenticular foreign bodies comprise about 5% to 10% of all intraocular foreign bodies and can result in serious complications. The management depends on some factors like size, location, material type and the risk of infection. We present a patient with an intralenticular metal foreign body in the left eye that, following initial treatment with topical steroid and antibiotic, underwent lens aspiration with removal of the intralenticular foreign body and insertion of a posterior chamber intraocular lens with good visual outcome.

Unusual orbital foreign bodies.

Retained intraorbital organic foreign bodies, particularly wooden, are commonly encountered in ophthalmologic practice. We treated two children who had sustained such injury while playing. They presented to us with non-healing sinus with purulent discharge. In one of the patients, X-rays and CT scan helped to clinch the diagnosis, whereas in the other patient diagnosis was possible by correlating history with clinical findings. Surgical exploration in both patients helped us to remove the foreign bodies. Surprisingly, both the foreign bodies were 7 cm long wooden pieces. We, however, caution that management of such cases should be conservative and that surgical exploration be done only in case of complication. From our experience, we recommend proper localisation by all possible means, blunt dissection, careful haemostasis coupled with excellent lighting and exposure in the atraumatic removal of intraorbital foreign bodies.

[Traumatic foreign body embolism from the basilic vein].

Foreign body embolisms can be traumatic and iatrogenic. Traumatic foreign body emulsion are almost always induced by gunshot wounds. Central vessels with a large lumen are the most frequent site of entry. Foreign bodies are transported to peripheral body areas or produce pulmonary embolism. Clinical manifestations are dependent on the size and place of the foreign body. In this report a case of traumatic foreign body embolism is presented, in which the basilic vein was the site of entrance and the foreign body was transported to the right lower lobe of the lung. Foreign body embolism should always be considered in the differential diagnosis in the case of patients with no visible foreign body in the injury. Treatment is dependent on the clinical signs and on size and shape of the foreign body. Symptomatic foreign body embolism and large irregularly shaped foreign bodies should be extracted. When only a small foreign body with no clinical symptoms is present conservative management is most appropriate.

Delayed diagnosis of laryngeal foreign body.

Aspiration of a foreign body is a recognized cause of accidental death in children. Paediatricians are aware of the symptoms of inhaled foreign bodies in the lower respiratory tract. However, symptoms which suggest impaction in the larynx do not appear to raise the same index of suspicion of a foreign body. One case of laryngeal foreign body is described with a delay in diagnosis of five days. The clinical presentation, investigations and management are discussed.

A simple "lasso" for intraocular foreign bodies.

Three patients had foreign bodies in their anterior chambers following penetrating ocular injuries. These foreign bodies were removed by a closed chamber technique using a simple loop. The loop was created by a 22-gauge intravenous cannula and a 7-0 polypropylene suture. Retained cilia in one patient and metallic foreign bodies in two patients were removed using this intraocular "lasso." Sutures were not placed at the incision sites at the end of the surgery. This is an inexpensive and easy to prepare technique that introduces minimal surgical trauma. In addition, two hands are not needed for loop manipulation. This technique may be an excellent alternative for removal of small intraocular foreign bodies.

[Foreign bodies in the anterior segment].

Foreign bodies in the anterior segment are different from those in the posterior segment regarding two specific aspects: they are frequently visible so defining their exact position is easier and surgical extraction is thus facilitated and the prognosis is better. However, infectious risk remains an important concern, especially in the case of an intraocular body, and foreign bodies must be considered in every anterior segment would. After an epidemiological review, foreign bodies of different anterior segment locations are discussed and surgical treatment is considered.

Intraretinal foreign bodies. Management and observations.

Foreign bodies embedded in the retina and choroid such that they cannot be extracted by a magnet and require vitreous surgical techniques for removal comprise a distinct sub-type of retained intraocular foreign body (IOFB). A retrospective evaluation of 16 such intraretinal foreign bodies (IRFBs), suggests that these injuries are frequently accompanied by extensive ocular damage, including corneal perforation, disruption of the lens, significant vitreous hemorrhage, retinal and choroidal hemorrhage and retinal detachment, all of which require immediate surgical attention. Delayed cataract and retinal detachment are often observed in these cases. More than 60% of this series developed macular pucker after IRFB removal. Visual outcomes were discouraging, with seven patients (44%) retaining only 20/200 or worse visual acuity. This review suggests that the structural and visual outcomes of such eyes are uncertain, are the products of complex processes involving numerous technical elements other than sophisticated surgery and prompt removal of the foreign body.

[Foreign body aspiration].

Aspiration of foreign bodies is a common cause of respiratory distress in children between the age of 6 months and 3 years. The diagnosis of radiopaque foreign bodies is easy when the whole respiratory tract is depicted. Nonopaque foreign bodies need a more differentiated diagnostic approach. The first step should be plain films in inspiration and expiration. The performance of additional chest radiographs, fluoroscopy and if need be CT or nuclear scans depends on the result of the plain films. The chest radiograph may reveal a variety of findings, the commonest of which is unilateral air trapping. Rarely, atelectasis, recurrent pneumonia at the same localisation and inspiratory obstruction are found. Combinations of the above-mentioned findings are possible. Moreover, the absence of positive radiological findings does not exclude the diagnosis of foreign body aspiration.

Bronchial foreign bodies in adults.

Aspiration of foreign bodies into the bronchial tree is infrequently seen in adults. We reviewed 40 such cases during an 8-year period at Chang Gung Memorial Hospital, Kaohsiung. Only six patients had underlying conditions that contributed to the aspiration of foreign bodies. A positive history of aspiration was found in 18 patients (48%). Clinical manifestations were nonspecific. Chest roentgenograms were useful in 11 of the 40 patients. Bronchoscopic findings were classified into three groups: foreign bodies in the bronchial tree without granulation tissue, foreign bodies in the bronchial tree with marked granulation tissue and foreign bodies embedded in the granulation tissue. The diagnoses and removal of foreign bodies were successful in 37 patients (92%) using grasping forceps or biopsy forceps and in one patient using basket type grasping forceps. Complications of bronchoscopy were rare and not serious. The diagnosis of occult foreign bodies is often difficult and demands a high index of suspicion. Removal of endobronchial foreign bodies is usually possible with a flexible fiberoptic bronchoscope and has a high success rate.

Experimental oral foreign body reactions: vegetable materials.

Foreign bodies and tissue reactions to foreign materials are commonly encountered in the oral cavity. Exogenous materials most commonly causing foreign body reactions are metallic in origin (usually amalgam). Of the nonmetallic materials seen during biopsies, suture materials and vegetable matter are most often observed. Since many foodstuff foreign materials are unidentifiable histologically, common vegetables were experimentally implanted subcutaneously in rats to assess local host responses and to characterize the nature of these materials microscopically. The histologic characteristics of these vegetable foreign body reactions are detailed herein. The implanted materials correspond to reactions seen in human subjects.

Tracheobronchial foreign bodies.

Aspirated and ingested foreign bodies continue to present challenges to otolaryngologists. The major issues involve the accurate diagnosis and speedy, safe retrieval of the foreign body. The accurate diagnosis may allude physicians because often the initial choking incidents are not witnessed and the delayed residual symptoms may mimic other common conditions. The retrieval of foreign bodies has been facilitated by technical improvements with the rod lens telescope, video endoscopy, a broad range of a variety of sized forceps, and safer anesthesia. This article reviews the clinical presentation, diagnostic work-up, and appropriate management of foreign bodies in the aerodigestive tract.

Rigid bronchoscopy for the suspicion of foreign body in the airway.

OBJECTIVE: Airway foreign bodies present a diagnostic dilemma and has been recognized for many years. Since aspiration of foreign bodies can be a serious and sometimes fatal problem, early intervention and proper management is vital. METHOD: In this retrospective study, the results of 1887 bronchoscopies, which were performed between the years 1973 and 2004 for the suspicion of foreign body aspiration in children, were presented. Various instruments and techniques were used over 31-year period and rigid bronchoscopy was the preferred method of foreign body extraction. RESULTS: There were 1106 boys and 781 girls with the median age of 2.3 years. Seventy-four percent of patients were less than 3 years old. The most common type of foreign body (89.9%) was organic; watermelon seeds (39.7%) were the most frequent organic foreign bodies. Eight hundred and twenty-three patients (43.6%) were referred to our clinic within the first 24h of the event while 4.5% of the patients were admitted to the hospital with the suspicion of foreign body in the airway later than one month. At bronchoscopy, a foreign body was identified in 79.1% of patients and no foreign body was seen in 20.9% of patients. Foreign bodies were encountered in 96.3% of the patients with positive history whereas 28.1% of the patients with negative history had foreign body. Of the patients with foreign bodies, 93.2% had positive history. Overall, the positive history was obtained from 85.2% of patients. The incidence of postbronchoscopic tracheotomy, thoracotomy, and overall mortality rate were 0.47, 0.15, and 0.21%, respectively. CONCLUSION: Otolaryngologists should consider foreign body aspiration in the airway in the differential diagnosis of any patient with the complaints of stridor, dyspnea, sudden onset of cough and intractable and recurrent lower respiratory tract infections. A careful history and physical examination were strong indicators of the diagnosis and raised the index of suspicion of an aspirated foreign body. Timely intervention with the experienced surgical team would decrease the complication rate and mortality rate. However, prevention of aspiration with the education of parents and caregivers is very important.

Intralenticular metallic foreign body.

BACKGROUND: Intralenticular metallic foreign bodies may be well tolerated for many years. CASE REPORT: A 24-year-old caucasian man was referred with an intralenticular metallic foreign body present in the left eye for five days. Following initial treatment with topical steroid and antibiotic, the lens remained clear and visual acuity normal. Two years later the left eye developed an anterior uveitis, with reduced vision. A left phacoemulsification lens extraction with removal of the intralenticular foreign body and insertion of a posterior chamber intraocular lens was performed. CONCLUSION: Management of intralenticular metallic foreign bodies may be conservative till intraocular inflammation or cataract develops.
