Detection of foreign bodies in the hand.

Fresh cadaver hands were used to compare the ability of routine x-ray, xeroradiography, computerized tomography, and magnetic resonance imaging to identify a variety of foreign bodies including glass, gravel, plastic, and wood in the soft tissue of the hand. All types of glass were easily seen by all imaging methods. Gravel foreign bodies were visible with all methods except magnetic resonance imaging where ferromagnetic streak artifacts obscured visualization. Plastic, although not seen by routine x-ray or xeroradiography, was faintly seen by computed tomography, and easily detected by magnetic resonance imaging. Wooden foreign bodies, especially when wet, were seen only by computed tomography and magnetic resonance imaging. Xeroradiography had no benefit over plain films in identifying foreign bodies and should be discarded in favor of computed tomography or magnetic resonance imaging when plain films are unrevealing. A practical guide for identifying foreign bodies in the soft tissues of the hand is presented.

Histologic evidence of foreign body granulation tissue and de novo lesions in patients with coronary stent restenosis.

OBJECTIVES: We examined the relative contributions of foreign body granulation and de novo lesions to neointimal hyperplasia in atherectomized specimens of restenosis after coronary stenting. BACKGROUND: Clinicopathological studies have suggested that smooth muscle cell (SMC) hyperplasia is the most likely cause of restenosis after coronary stenting. It is not yet fully understood how SMC hyperplasia occurs or how SMCs stimulation can lead to intimal hyperplasia. Although inflammation has been postulated to be a major contributor to restenosis after coronary stenting, there is a paucity of data on the relationsip between inflammation and subsequent neointimal formation in humans. Only in a porcine experimental model of stent restenosis, foreign body granulation tissue as a cause of inflammation in stent restenosis was reported. METHODS: Tissue specimens were retrieved by directional atherectomy from 11 patients in whom stent restenosis developed after percutaneous revascularization of coronary artery disease. For specimens preserved in 10% buffered formalin, analysis of cellular composition was performed quantitatively after cell-specific immunostaining, i.e. CD68, UCHL-1, HLA-DR, smooth muscle actin, vimentin, desmin, PCNA and TGF-beta. RESULTS: Five of the 11 patients showed granulation tissues 3-6 months after stent implantation, of whom 3 patients revealed foreign body multinucleated giant cells around the stent struts where PCNA- and vimentin-positive SMCs were demonstrated. Calcification and de novo lesions in medial and adventitial tissues were observed in 3 other patients, and fresh and/or organized thrombi were documented in 3 of the 11 patients. CONCLUSIONS: These findings support the notion that stent restenosis results from SMC hyperplasia and suggest that the foreign body granulation tissue against metals of the stents and de novo lesions could play an important role in chronic inflammation leading to intimal hyperplasia and subsequently to stent restenosis in some patients. Clinicians should thus consider whether a patient may be allergic to stent components with unknown reaction, e.g. haptens.

[Use of ultrasound for diagnosis of foreign bodies of the brain].

With the aid of modern ultrasonic diagnostic devices experiments were conducted in order to receive signals from foreign bodies of a different composition, non-radiocontrast ones including. Experiments on 10 human brain preparations revealed the typical peculiarities of echo-signal from foreign bodies in the cerebral matter. In 30 adult mongrel dogs it was proved that foreign bodies can be diagnosed in the course of primary and secondary debridement of skull and brain wounds. It was found that the shape and size of the foreign bodies in the human brain can be most explicitly determined with the aid of a specially designed device having a high azimuthal resolution.

Inguinal lymph node foreign body granulomas after placement of a silicone rubber (Silflex) implant of the first metatarsophalangeal joint.

We describe a woman who developed foreign body granulomas 8 years after metatarsophalangeal (MTP) joint silicone rubber implantation for hallux rigidus. She developed overnight swelling and tenderness in the inguinal region on the ipsilateral side. Histological evaluation of the lymph node showed foreign body granulomas. Electron microscopy and dispersion x-ray analysis identified the foreign body material in the inguinal lymph node and fibrous capsule surrounding the implant as silicone. Foreign body granulomas of surrounding tissues and regional lymph nodes are infrequently reported postoperative complications in patients with small joint silicone rubber implants. A fractured or eroded implant surface attributed to wear is usually noted at prosthesis excision. Granulomas in normal or enlarged lymph nodes have been described in both symptomatic and asymptomatic patients, with intact or fractured prostheses. Many related joint and lymph node symptoms resolve with removal of the silicone rubber prosthesis.

Fatal prolonged foreign body aspiration following an asymptomatic interval.

Patients with nondiagnosed foreign body aspiration usually have persistent symptoms and occasionally die. We are reporting two patients with histories suggestive of foreign body aspiration who were not definitively studied because of resolving symptoms. Both children became asymptomatic but subsequently developed acute, total airway obstruction and died. These cases demonstrate the difficulty of diagnosing aspiration and the necessity of timely intervention.

'Hunt the thimble': a study of the radiology of ingested foreign bodies.

The role of radiology in the management of patients with a history of ingested foreign bodies is reviewed in a retrospective study over a 2-year period in a Children's Hospital. If radiography was confined to those children who have a clinical history suggestive of foreign body impaction in the oesophagus, a foreign body aspiration or having swallowed a button battery, the work load and unnecessary radiation arising from this practice could be halved. This study demonstrates another misuse of radiological services.

Endobronchial epithelial papilloma associated with a foreign body.

Noninvasive papillary endobronchial lesions are among the least common of pulmonary neoplasms. We describe the occurrence of a papillary squamous tumor surrounding an aspirated sunflower seed foreign body, and briefly review the subject of endobronchial papilloma. This tumor should be a red flag for the presence of a foreign body, and foreign body removal may obviate the need for thoracotomy.

Penetrating neck injuries involving wooden foreign bodies: the role of MRI and the misinterpretation of CT images.

A 12-year-old, boy fell in the bush and suffered a penetrating neck wound. Computed tomography(CT-scan) was performed, but no foreign body was detected inside the wound. The patient returned home after ordinary wound care. About 6 months after the accident, the patient visited hospital, because of inflammatory neck pain. A CT-scan was performed and the foreign body appeared as a high density. Magnetic resonance imaging (MRI) revealed the presence of a large foreign body. Under general anesthesia the wooden (bamboo) foreign body was removed. This case highlights the needs to be aware of the potential for misinterpretation of CT images, especially in acute wooden penetration injury. Its also demonstrates that MRI is a useful adjust to CT in the detection of non-metallic foreign bodies.

[The danger of removing some esophageal foreign bodies by fiber optics].

The authors presented 4 cases of patients with a foreign body in the esophagus, which has been tried to remove by means of fiberoscopy and rigid esophagoscopy. The fiberoptic endoscopy has failed either as a diagnostic method or as a therapeutic one. The classical esophagoscopy has turned out to be much better in both cases. The fiberoscopy is a valuable diagnostic and therapeutic procedure in a lot of diseases of digestive tract. Especially it is useful in order to remove some foreign bodies from the esophagus, but at the same time it fails when removing big foreign bodies (e.g. parts of false teeth, large bones). In these cases rigid esophagoscopy is the only effective method when performed under endotracheal anesthesia and with esophageal muscles relaxation.

Foreign body localization by computed tomography.

Computed tomographic scanning for foreign body localization may be of increasing usefulness because of the instrument's fine resolution capabilities. Because surgical intervention is the usual result of a foreign body probe of the eye, it is essential that precise localization be accomplished.

Tubular foreign body or stent: safe retrieval or repositioning using the coaxial snare technique.

OBJECTIVE: To evaluate the utility and advantages of the coaxial snare technique in the retrieval of tubular foreign bodies. MATERIALS AND METHODS: Using the coaxial snare technique, we attempted to retrieve tubular foreign bodies present in seven patients. The bodies were either stents which were malpositioned or had migrated from their correct position in the vascular system (n=2), a fragmented venous introducer sheath (n=1), fragmented drainage catheters in the biliary tree (n=2), or fractured external drainage catheters in the urinary tract (n=2). After passing a guidewire and/or a dilator through the lumina of these foreign bodies, we introduced a loop snare over the guidewire or dilator, thus capturing and retrieving them. RESULTS: In all cases, it was possible to retrieve or reposition the various items, using a minimum-sized introducer sheath or a tract. No folding was involved. In no case were surgical procedures required, and no complications were encountered. CONCLUSION: The coaxial snare technique, an application of the loop snare technique, is a useful and safe method for the retrieval of tubular foreign bodies, and one which involves minimal injury to the patient.

[Percutaneous extraction of a foreign body from the right ventricle. Clinical case].

Percutaneous retrieval of intravascular foreign bodies has emerged as a standard method of treatment, which audits major surgery. This procedure was performed in a patient with a fragment of a broken introducer sheath located in the right ventricle with risk of arrhythmias. Extraction was difficult because the sheath was trapped in the tendinous cords. The foreign body was embolized to the pulmonary artery and extraction was performed. No clinically significant complications occurred.

Foreign bodies in the foot.

A symptomatic foreign object lodged in the foot can be a difficult problem. The object's location and shape are the most important factors to identify before removal of the object is attempted. Many different imaging modalities have been used to locate the foreign objects in the foot. The authors briefly reviewed several common imaging modalities. Computed tomography appears to be superior to the other imaging modalities discussed in visualizing and localizing foreign objects in the foot. Magnetic resonance scanning is probably equal to computed tomography but is less readily available and more expensive and is contraindicated with ferrous metal foreign bodies.

[Foreign bodies in the esophagus of adults].

A prospective descriptive observational study was made to determine the incidence of esophageal foreign bodies in adults who had been admitted to the Manual Ascunce Domenech teaching hospital of Camaguey, Cuba in the period from 1 September 1997 to 31 August 1998. The highest frequency of patients with this diagnosis was in 31 to 50 year-old men. Dysphagia and salivary retention in the pyriform sinuses were the prevalent symptoms. The state of the oral cavity was poor in 82.50% of patients. The foreign body was removed in the first 24 hours in 83.33% of patients. The radiological diagnosis was positive in 75% of patients. The upper third was the most common location in radiological and endoscopic studies. Fish bones were the prevalent foreign body. A quarter of the patients had complications and stable esophagoscopy was used to extract the foreign body in 96.67% of cases.
