Ultrasound biomicroscopy as a tool for detecting and localizing occult foreign bodies after ocular trauma.

OBJECTIVE: To show the utility of ultrasound biomicroscopy (UBM) in imaging small ocular foreign bodies of the anterior segment. DESIGN: Retrospective case series. PARTICIPANTS: Twelve eyes of 12 consecutive patients evaluated in the emergency department or referred to specialty services at 1 institution between August 1994 and November 1997 were examined. INTERVENTION: Ocular ultrasound biomicroscopy was performed. MAIN OUTCOME MEASURES: Detection and localization of an ocular foreign body were measured. RESULTS: An intraocular or superficial foreign body was detected by UBM in 9 (75%) of 12 eyes. The foreign body was classified as corneal in two eyes, subconjunctival in two, intrascleral in three, and intraocular in two eyes. The foreign body was not visible by ophthalmic physical examination in seven of the nine eyes with a confirmed ocular foreign body. In the remaining two eyes, UBM was used to determine the depth of a visible foreign body. In three of the eyes with a confirmed foreign body, computed tomography and/or contact B-scan ultrasonography was obtained and failed to show a foreign body. Six of the foreign bodies were nonmetallic. CONCLUSIONS: Clinical detection of ocular foreign bodies after trauma can be hindered by small size, haziness of the optical media, poor patient cooperation, or hidden location. Ultrasound biomicroscopy is a valuable adjunct in the evaluation of suspected ocular foreign bodies, especially in cases involving small, nonmetallic objects.

A prospective study of foreign-body ingestion in 311 children.

OBJECTIVE: To determine the preferable management protocol of foreign body ingestion in pediatric patients. METHODS: All pediatric patients aged less than 12 years who presented with suspected foreign body ingestion in a hospital setting over a period of 3 years were prospectively studied. The usefulness of symptoms and various diagnostic procedures to identify the impacted foreign bodies were analyzed. RESULTS: Of 311 children aged 4 months to 12 years, 115 foreign bodies were encountered. The presentations in children aged younger than 5 years were markedly different from the older children, who behaved more like adults. All sharp foreign bodies (107 cases or 93%), mostly fish bones (90.4%), were found in the oropharynx under direct vision using either tongue depressor (57%), Macintosh laryngoscope (6%), indirect laryngeal mirror (2%) or transnasal flexible endoscopy (28%). Coins (eight cases or 7%) were the only foreign body impacted at or below the level of cricopharyngeus. A plain cervical X-ray has a low sensitivity (15.9%) and a high specificity (99.5%) in identifying the foreign bodies. CONCLUSIONS: As the majority of the foreign bodies were sharp bones and situated in the oropharynx, a management protocol involving examination with a tongue depressor, transnasal laryngoscope, selective lateral soft tissue neck X-ray, chest X-ray and watchful observation is usually adequate. Removal of these foreign bodies can be accomplished using a tongue depressor and Macintosh laryngoscope. Patients with a suspected coin ingestion have to be evaluated by X-ray, and a rigid pharyngo-oesophagoscopy should be the mainstay of treatment.

[Cardiac metal foreign body: analysis of 21 cases].

OBJECTIVE: To improve early diagnosis and clinical treatment of metal foreign body in the heart. METHODS: In 21 patients, case history, clinical manifestation, chest X-ray film, and echocardiograph were reviewed. 20 patients received operation: emergency exploration (13) and elective operation (7). Four patients were subjected to cardiopulmonary bypass. The other one was not operated on because of absence of symptoms and small foreign body. Foreign bodies mostly bullets, were usually located in the right ventricle. Ventricular fibrillation occurred in 3 patients during operation, two of them were resuscitated. RESULTS: 20 patients but one recovered, a mortality rate of 5%. CONCLUSIONS: Early diagnosis, rapid management, and localization of foreign body are essential to the selection of treatment.

Surgical removal of nonmagnetic foreign bodies.

A microsurgical technique for the removal of nonmagnetic foreign bodies in eyes with opaque media incorporated the simultaneous use of the foreign body forcepts with a vitrectomy machine equipped with fiberoptics. The superb viewing system provided by the operating microscope combined with the excellent illumination from intraocular fiberoptics offered precise surgical control. Nonencapsulated nonmagnetic foreign bodies in eyes with clear vitreous cavities were removed by using the operating microscope, corneal contact lens, and foreign body forceps introduced through a pars plana location. Vitrectomy was not performed. The surgical techniques allowed early removal of the foreign body and, in a preliminary series of cases, improved visual results in what is usually a devastating ocular injury.

Endoscopic removal of sharp foreign bodies impacted in the esophagus.

BACKGROUND AND STUDY AIMS: Impacted sharp foreign bodies in the esophagus can be very difficult to manage. When attempts are made to remove such objects inappropriately, life-threatening complications such as perforation can occur. The aim of this study was to evaluate the safety and efficacy of endoscopic removal of impacted sharp foreign bodies in the esophagus using proximal dilatation with an oral side balloon or transparent cap. PATIENTS AND METHODS: A total of 22 patients (10 men, 12 women) with impacted sharp foreign bodies in the esophagus underwent endoscopic extraction. The following technique was successfully performed at our hospital. An oral side balloon (Top Co., Japan) for esophageal variceal sclerotherapy was attached to the distal part of the endoscope. With the patient under local anesthesia, the endoscope was inserted as far as the proximal part of the esophageal foreign body. The oral side balloon was then gradually inflated. Dilatation of the proximal part of the esophagus made it possible to release the impacted sharp foreign body from the esophageal wall. A transparent cap was used for foreign bodies in the upper esophagus when there were difficulties with the oral side balloon. RESULTS: The types of foreign body removed were fish bones (n = 9), press-through packages (n = 8), chicken bones (n =3), dentures (n = 1), and a wrist watch (n = 1). Endoscopic removal was successful in all but one of the cases, in which a fish bone had to be extracted surgically. CONCLUSIONS: The proximal dilatation method using an oral side balloon or transparent cap is safe and effective in removing sharp foreign bodies from the esophagus, avoiding surgery and possible perforation.

Foreign bodies in the hand in children.

Foreign bodies in the hand in children are best managed when the surgeon has a well-organized approach to the total problem. The procedure of restraining a child, infiltrating the wound with local anesthetic, and probing the wound deep in the hand on the day of injury to remove the foreign body is discouraged. A detailed examination of the hand for cut tendons and nerves should be done. The initial treatment should be thorough cleaning of the skin, application of compresses wet with Bunnell's hand solution, systemic antibiotics, and tetanus prophylaxis. The foreign body is removed, as an elective surgical procedure, only if there is evidence of infection or persistent pain or both. Six weeks after all evidence of infection has cleared appropriate reconstructive procedures can be done.

[How to reduce the incidence of complication and mortality in pediatric tracheobronchial foreign body patients].

OBJECTIVE: To analyze the experience for the diagnosis and treatment of pediatric tracheobronchial foreign body cases, so to the incidence of complications and mortality. METHODS: 7260 tracheobronchial foreign body cases, from 1987 through 2003, were enrolled in this study. Early diagnosis, preoperative evaluation and perioperative treatment were strongly emphasized in this group of patients. RESULTS: 7618 patients received rigid bronchoscopy and 7260 cases were confirmed with tracheobronchial foreign bodies. The confirmed diagnosis rate is 95.3%. Among the 7260 cases, 7007 (96. 4% ) patients were diagnosed and received bronchoscopic foreign body removal within 24 hours. Different food is the most common foreign body aspirated in infants and toddlers (under 4 year old), whereas older children are more likely to aspirate other foreign bodies. Peanuts and sunflower seed (6862) were noted as the most common ones. Pen caps (398) are much less. All patients were evaluated before surgery after 1996. Complications occurred in 7 patients (0.1%) . The mortality rate is zero. 7165 cases' foreign body were successfully removed the first time of brochoscopy. 95 patients received more than one times bronchoscopy. 67 cases' foreign bodies were smoothly removed with second bronchoscopy. 16 cases received flexible bronchoscopic foreign body removal when rigid bronchoscopic procedure failed. 12 cases received chest surgery for foreign body removal. 6933 cases received bronchoscopy with surface anesthesia or without anesthesia, while 327 patients with general anesthesia combined local surface anesthesia. CONCLUSIONS: Rapid diagnosis and treatment can reduce the complication and mortality rate. So that early diagnosis, preoperative evaluation and perioperative treatment should be strongly emphasized.

Complications of bronchoscopy for foreign body removal: experience in 1,035 cases.

BACKGROUND: Tracheobronchial foreign body aspirations, which threaten lives in childhood, also carry potential risks during and after bronchoscopy. The aim of this study is to review complications and precautions that need to be taken against possible risks. METHODS: From 1987 to 2005, bronchoscopy was done in 1,035 children in our department on suspicion of foreign body aspiration. The average age of these patients, mostly male (55%), was 4.1 years. Medical history, physical examination, radiological methods and bronchoscopy were used in the diagnosis. Bronchoscopy was applied under general anaesthesia, and the respiratory and cardiac systems were closely observed for 4 hours after the process. RESULTS: Nine hundred eleven of 1,035 patients (88%) had a foreign body in the tracheobronchial system. In 42 of the patients, infection required aggressive medication; in 30, hypoxia and bradycardia occurred as a result of obstruction during bronchoscopy; in 37, laryngeal edema, laryngeal spasm and/or bronchospasm required ventilation support; in 6 patients, tracheobronchial system bleeding occurred; in 2 patients pneumothorax occurred, in 1 patient pneumomediastinum was observed and 6 patients needed thoracotomies because of foreign body aspiration. In this series there were 8 deaths. CONCLUSION: Bronchoscopy, performed for tracheobronchial foreign body aspiration, carries a potential life-threatening risk during and after the process. The clinician needs to be aware of these risks, take proper precautions, and perform bronchoscopy by taking the medical condition of the patient and characteristics of the inspired foreign body into consideration.

Inhalation of foreign bodies in Chinese children: a review of 400 cases.

A retrospective review of 400 Chinese children who had inhaled foreign bodies was undertaken. There has been a yearly increase in the total number of cases of airway foreign bodies removed in our hospital. Fifty-eight percent of the children presenting were from the countryside; 42% were townspeople. Approximately 90% of the patients were under 3 years of age, with the peak incidence of foreign body inhalation occurring between 1 and 2 years of age (57.8%). The male-female ratio was about 1.2:1. About 95% of the removed foreign bodies were organic in origin. The majority of the foreign bodies were found most often in the right bronchial tree (46%). A positive history of foreign body inhalation was obtained in 98% of the cases. Twenty-eight percent of the children presented at the hospital within 24 hours, 71% within 1 week, and 29% more than 1 week after inhaling the foreign body. The most common presenting symptoms of laryngotracheal foreign bodies were cough, wheezing, dyspnea, and hoarseness; those of bronchial foreign bodies were cough, wheezing, decreased air entry, and rhonchi. More than two-thirds of the children with larygotracheal foreign bodies had normal x-ray findings. The most common fluoroscopic findings in those children with bronchial foreign bodies were mediastinal shift (36.8%), obstructive emphysema (35.7%), and normal findings (35%). A total of 348 (87%) bronchial foreign bodies were removed by rigid bronchoscopy (81%), rod-lens bronchoscopy (5%), and spontaneous expulsion (1%); 52 (13%) laryngeal and tracheal foreign bodies were removed by direct laryngoscopy (12%) and tracheotomy (1%). A single endoscopic procedure successfully removed 92.5% of 400 foreign bodies detected in the airways. One child died during bronchoscopy, for a mortality rate of 0.25%.

The CC chemokine ligand, CCL2/MCP1, participates in macrophage fusion and foreign body giant cell formation.

The foreign body reaction (FBR) develops in response to the implantation of almost all biomaterials and can be detrimental to their function. The formation of foreign body giant cells (FBGC), which damage the surface of biomaterials, is considered a hallmark of this reaction. FBGC derive from blood-borne monocytes that enter the implantation site after surgery in response to the release of chemotactic signals. In this study, we implanted biomaterials subcutaneous (s.c.) in mice that lack the monocyte chemoattractant CC chemokine ligand 2 (CCL2) and found that biomaterials were encapsulated despite reduced FBGC formation. The latter was due to compromised macrophage fusion rather than migration. Consistent with the reduction in FBGC formation, biodegradable biomaterials sustained reduced damage in CCL2-null mice. Furthermore, blockade of CCL2 function by localized gene delivery in wild-type mice hindered FBGC formation, despite normal monocyte recruitment. The requirement for CCL2 in fusion was confirmed by the ability of both a CCL2 inhibitory peptide and an anti-CCL2 Ab to reduce FBGC formation from peripheral blood monocytes in an in vitro assay. Our findings demonstrate a previously unreported involvement of CCL2 in FBGC formation, and suggest that FBGC are not the primary determinants of capsule formation in the FBR.

[Management of foreign bodies in transparent lens and a long-term follow-up--the analysis of 25 cases].

25 cases of foreign bodies in transparent lens are reported in this paper. The foreign bodies retained in transparent lens are rare intraocular foreign bodies. In all cases, the foreign bodies were magnetic and the injured lens had local opacity. In 20 cases of them, the foreign bodies were removed by different magnets according to the different sites of the foreign bodies retained in transparent lens. In most cases the effect was sufficient. The patients were followed-up postoperatively during different period. The visual acuity was quite good. Effect of the foreign bodies on the transparent lens, and the management of the foreign bodies in transparent lens and the operative methods for removal of the foreign bodies in the transparent lens are discussed.

Computerized axial tomography in the detection of intraocular foreign bodies.

CAT scanning was used in the localization of intraocular and periorbital foreign bodies in 36 consecutive patients. The method was found to be convenient, well-tolerated by the patient, and provided accurate and useful clinical information. Six cases are described to illustrate clinical situations where traditional localizing methods were unable to supply satisfactory information and where CAT scanning proved to be of significant assistance. This included uncooperative patients, multiple foreign bodies, anterior foreign bodies, and foreign bodies adjacent to the posterior scleral wall.

Unusual foreign bodies of the temporal bone.

Foreign bodies that result from traumatic injury may be the cause of many clinical symptoms. Chronic otitis externa is one of the many clinical symptoms following a traumatic perforation of a foreign body from the oral cavity penetrating the deep tissue of the neck and ultimately lodging in the external ear canal. We discuss two such uncommon cases.

Foreign bodies in sarcoidosis.

Sarcoidosis is a multisystem disease of unknown etiology. The demonstration of polarizable foreign bodies in cutaneous granulomas is generally thought to exclude a diagnosis of sarcoidosis. Nevertheless. some investigators have reported systemic sarcoidosis with cutaneous manifestations in which polarizable particles were associated with granuloma formation in the skin. We searched the biopsy specimens of granulomatous lesions from 50 patients with cutaneous sarcoidosis using polarization microscopy to estimate the frequency of polarizable foreign bodies in cutaneous lesions of sarcoidosis. Using electron probe microanalysis, we sought to determine what elements compose these foreign bodies. Polarizable foreign bodies were found in the granulomatous skin lesions of 12 of 50 patients with cutaneous sarcoidosis. All 12 patients also had at least one other granulomatous systemic lesion, and 4 had biopsy specimens of a systemic lesion available for review. Polarizable foreign bodies were found in two cases. The elements identified were calcium, phosphorus, silicon, and aluminum. Polarizable foreign bodies were found in cutaneous sarcoidosis far more often than expected. Foreign bodies were also found in granulomatous systemic lesions. The foreign body may serve as an inciting stimulus for granuloma formation in selected cases of sarcoidosis.

Multiple foreign body ingestion and ileal perforation.

Foreign body ingestion is a common problem encountered in the pediatric age group. The swallowed object is often passed with little or no morbidity. Problems ensue if the ingested foreign body is hazardous, is multiple, or becomes impacted. We describe an ileal perforation following the ingestion of an alkaline disc battery, a magnet, and a steel ball impacted in the ileum for about 48 h. The magnet and the steel ball were attracted to each other, forming a composite unit. The disc battery and the magnet were attracted to each other across a loop of ileum, causing necrosis and perforation of the ileum.
