[Foreign body of bladder in children].

The thirty-years experience of diagnosis and treatment of the bladder foreign body in children was summarized. There were treated 19 children with the bladder foreign bodies in the clinic. There were 12 (63.12%) girls and 7 (36.88%) boys, aged from 3 to 15 years old. Three mechanisms of penetration of foreign bodies into the bladder were delineated: by retrograde way via urethra; while gun-shot wounding, trauma or due to migration from surrounding tissues and organs; as the consequence of faults, committed during performance of operations or therapeutic-diagnostic procedures. In 14 patients the foreign bodies were removed transvesically and in 5--transurethrally. All the patients had recovered. Complications did not occur. Late results were studied up.

Inhaled foreign bodies in children.

We review a series of 115 children who attended the Royal Children's Hospital in Melbourne between 1979 and 1982 with the diagnosis of inhalation of a foreign body, or in whom a foreign body was found at bronchoscopy. Children between the ages of one and three years were the most commonly affected (75%) and boys outnumbered girls in the ratio 3:2. In 16% of cases the child did not present until more than one week after inhaling the foreign body. A peanut was the most common foreign body found (52% of cases), and it seems that many parents are still unaware that peanut ingestion can be hazardous in very young children.

Percutaneous extraction of centrally embolized foreign bodies: a report of 16 cases.

Sixteen cases of centrally embolized foreign bodies are reported (eight catheter fragments, two guide wires, four pacemaker electrodes, one ventriculo-atrial shunt, one Port-A-Cath catheter). In all patients only the Dormia basket was used. Foreign body extraction was successful in all patients except one, in which removal of a pacemaker electrode from the myocardium failed. Technical aspects as well as complications of percutaneous foreign body extraction are discussed.

The ultrasonic detection of soft tissue foreign bodies.

The ability of B-scan ultrasonography to detect soft tissue foreign bodies of various sizes and composition was investigated in a canine model. Foreign bodies consisting of wooden rods 0.7 mm and larger, lead-free glass rods 2.0 mm and larger, plastic rods 3.9 mm and 5.6 mm, and metal needles 0.5 mm and larger were embedded in fleshy soft tissue. All objects examined were discernible. Wood is best visualized followed by glass, plastic, and metal. Ultrasound may be a valuable noninvasive means of detecting soft tissue foreign bodies; further investigation to delineate its clinical role is warranted.

Resolution of severe bronchiectasis after removal of long-standing retained foreign body.

Saccular bronchiectasis secondary to the presence of a long retained foreign body is considered irreversible and an indication for resection of the diseased segment or lobe. We describe a 3 1/2 year-old girl with a retained organic foreign body for 18 months, and who was treated conservatively after laser resection and extraction of the inflammatory mass from the bronchus intermedius followed by complete resolution of the bronchiectasis. We suggest that even severe bronchiectasis following prolonged retention of a foreign body may be reversible after removal of the obstruction and reestablishment of airway patency.

Foreign body aspiration following unconventional use of a metered dose inhaler.

PURPOSE: Aspiration of a foreign body may be life-threatening. This report describes laryngeal obstruction after inhalation of a piece of a Turbuhaler which resulted from a patient tampering with the device. CLINICAL FEATURES: A 27-yr-old man disassembled a Turbuhaler and inadvertently aspirated a plastic dispensing medication disc (22 mm diameter) while attempting to inhale the remnant terbutaline sulfate which accumulated on it. Although the patient was hoarse, he was not in acute respiratory distress. X-ray revealed the disc lodged in the larynx below the vocal cords. The patient was immediately transferred to an operating theatre, and a drying agent (glycopyrrolate), judicious sedation (midazolam and fentanyl) and O2 were administered. The airway was anesthetized with lidocaine 4% delivered using high-flow O2 through an atomizer. Direct laryngoscopy revealed a partially obstructed view of the disc lodged distal to the vocal cords which was inaccessible for retrieval. Loss of consciousness was subsequently induced by spontaneous mask ventilation with sevoflurane (in O2). The airway was visualized using a suspension laryngoscope and the foreign body was removed with grasping forceps. The patient was awakened, transferred to the ICU and given 4 mg decadron i.v. every eight hours (two doses). Laryngoscopy prior to discharge indicated good mobility of the vocal cords and normal glottic structure. CONCLUSION: Aspiration of a foreign body is a potentially life-threatening situation requiring coordination between anesthesiologist, surgeon, and nursing staff. Anesthetic goals include avoidance of upper airway obstruction and maintenance of adequate ventilation while the foreign body is retrieved. Provisions must be made for tracheostomy if these goals cannot be realized.

[Possible computed tomographic and magnetic resonance tomographic detection of wood foreign bodies following perforating eye injuries].

After perforating eye injury the retention of a foreign body in the orbits has to be excluded. Wooden foreign bodies mostly have negative density on CT, which increases later as a result of granulomatous changes. On MRI, pieces of wood appear with low signal intensity, and only in some cases is a collar-shaped structure recognizable, allowing differentiation from gas. Soon after orbital trauma with splinters of wood, therefore CT allows better differentiation of pieces of wood from intraorbital gas by measurement of their density, whereas MRI, makes it possible to demonstrate wooden foreign bodies in older injuries in spite of granulomatous changes.

Computed axial tomography localization of intra-orbital foreign body.

Conventional radiographs in a patient with an intra-orbital foreign body showed that it was close to the back of the globe. Computed axial tomography showed that it lay beside a swollen and probably lacerated optic nerve. The advantages of CT scanning in the investigation of intra-orbital foreign bodies are outlined.

Langhans-type and foreign-body-type multinucleated giant cells in cutaneous lesions of sarcoidosis.

Multinucleated giant cells are characteristic of a monocyte-macrophage lineage in sarcoidosis and consist of two types of cells: Langhans-type with an arcuate arrangement of nuclei and a foreign-body type with random arrangement of nuclei. To compare these cells in the cutaneous lesions of sarcoidosis, we histologically and immunohistologically examined multinucleated giant cells in 25 scar infiltrations (cutaneous sarcoidosis with foreign bodies) and 30 cutaneous lesions of sarcoidosis without foreign bodies. Regardless of the presence or absence of foreign bodies, the cutaneous lesions had both types of multinucleated giant cells, usually with a predominance of the Langhans-type, although the numbers of total multinucleated giant cells were higher in scar infiltrations than in cutaneous sarcoidosis without foreign bodies, suggesting that their frequency is influenced by the microenvironment in sarcoidal lesions such as the presence of foreign bodies. Immunohistochemical studies using surface antigens of monocyte-macrophage lineage cells and adhesion molecules indicated that both types of multinucleated giant cells are formed from monocytes rather than tissue macrophages and are phenotypically the same cells with different distributions of nuclei.

[Primary bronchial actinomycosis and foreign body].

This paper presents the fourth case reported on the association of primary bronchial actinomycosis and foreign body. The pathogenesis of this rare association has been linked to the low respiratory tract and a foreign body (chicken bone); it depends on its characteristics and how long it has remained lodged into the bronchial tree. The diagnosis of this case was very difficult and late. Several endoscopy procedures were required in order to detect it. Our patient has been treated successfully with parenteral penicillin in association with an original bronchoscopic procedure using a laser technique to find the foreign body and take it out of the respiratory tract. We consider that it is necessary to remember this association in every patient who suffers from recurrent pneumonia, in those who are at risk of foreign body aspiration and when the presence of an endobronchial mass is suspected.

Thin-section axial multidetector computed tomography and multiplanar reformatted imaging of children with suspected foreign-body aspiration: Is virtual bronchoscopy overemphasized?

PURPOSE: To determine the added value of multidetector computed tomography (MDCT)-assisted virtual bronchoscopy (VB) to axial MDCT and multiplanar reformatted (MPR) imaging with respect to conventional bronchoscopy in the evaluation of children with suspected foreign-body aspiration (FBA). MATERIAL AND METHODS: Twenty-one consecutive children (14 male, seven female, age 8 months-7 years, mean age 3.5 years) presenting with the suspicion of FBA were examined with 16-slice MDCT using 100-120 kV, 30-50 mA, 1-mm section thickness, 1.2 pitch ratio, and 0.6-1.0-mm reconstruction interval. Before CT examinations, chest radiographies were also obtained in all cases. VB and MPR imaging were carried out after MDCT examinations. RESULTS: Nine foreign bodies were identified by gold-standard conventional bronchoscopy. VB, thin-section axial MDCT, and MPR images identified eight of nine foreign bodies. CT scans with MPR images and VB did not reveal a chronic foreign body; and, in one patient, endobronchial mucous was diagnosed as the foreign body. The sensitivity, specificity, and accuracy of thin-section axial MDCT and MPR images alone in the diagnosis of FBA were 88.9%, 91.7%, and 90.5%, respectively. Results were the same as those obtained when VB was also included. CONCLUSION: MDCT with VB and axial/MPR images provide equally valuable information in children with suspected foreign-body aspiration and prevent unnecessary conventional bronchoscopic examinations. However, VB increases total examination time and cost, and it does not provide additional information over MPR images in the evaluation of foreign-body aspiration.

[Life threatening late dislocation in chronic foreign body aspiration].

We report a case of a boy with a long-standing foreign body aspiration in the left main bronchus causing severe pneumonia of the left lung. During intravenous therapy with antibiotics there was a life-threatening event with acute dislocation of the foreign body into the right main bronchus, leading to acute respiratory insufficiency. We conclude that in chronic foreign body aspiration antibiotic therapy preceding bronchoscopy should only be performed in in-patients and with strict monitoring.

Systemic anti-IFN-gamma treatment and role of macrophage subsets in the foreign body reaction to dermal sheep collagen in rats.

The application of a biomaterial induces a foreign body reaction. By controlling this reaction, biocompatibility could be improved. We previously demonstrated that impregnation of a biodegradable biomaterial with antibodies against interferon-gamma (IFN-gamma) inhibits the foreign body reaction. In this study we investigate whether systemic administration of the antibody can induce similar reactions. Several parameters are compared between control and anti-IFN-gamma-treated rats: cellular ingrowth; degradation of the biomaterial; ingrowth of macrophage (MO) subsets, T cells, B cells, NK cells, and granulocytes; and expression of the major histocompatibility complex class II (MHC class II) molecule on antigen presenting cells. Treatment with anti-IFN-gamma results in increased cellular ingrowth and biomaterial degradation and a decreased expression of MHC class II. Overall, systemic treatment with anti-IFN-gamma is insufficient to modulate the foreign body reaction. This suggests an alternative mechanism for MO activation besides IFN-gamma. The role of T cells and MO subsets in the foreign body reaction is discussed.

Role of scheimpflug imaging in traumatic intralenticular foreign body.

PURPOSE: The role of Pentacam Scheimpflug imaging in evaluation of penetrating eye injury and intralenticular foreign body (ILFB). DESIGN: Interventional case report. METHODS: A 35-year-old male presented to our clinical practice with penetrating eye injury and endophthalmitis. Scheimpflug imaging helped localize the intralenticular foreign body (ILFB). It confirmed the posterior capsule to be intact. He underwent phacoemulsification, foreign body removal, and intraocular lens (IOL) implant. Postoperatively, IOL was imaged with Pentacam Scheimpflug imaging. RESULTS: Scheimpflug imaging allowed us to confirm the presence and exact location of ILFB and its relation to the intact posterior capsule as well as the postoperative IOL positioning. This helped in better planning of management of traumatic cataract with ILFB. CONCLUSIONS: Pentacam is a potential tool for accurate localization of foreign bodies lodged in the lens and provides an objective basis for better patient counseling and surgical planning.

Fish bones and other foreign bodies.

In this prospective study the types of foreign body ingested, sites of impaction, radiographical findings, management and outcome in 81 patients were recorded. We have demonstrated that foreign bodies can be conveniently divided into 'fish bones' and 'others', in terms of their sites of impaction (P < 0.0001), the age groups affected, whether dentures were worn or not (P < 0.02) and their respective management (P < 0.001). Statistical analysis supporting these observations has not been previously reported.

Retained digital foreign body after a pellet gun injury.

A symptomatic foreign body embedded in the human body can be a frustrating problem for physician and patient alike. A unique case of a retained foreign object resulting from a pellet gun injury has been presented. Although the course of treatment in this case was uncomplicated, it is important to understand the complexities of the human body's response to foreign bodies.

[Moth fragments as intraocular foreign bodies].

The authors describe an accident leading to penetration of the eye of an 11-year-old boy by an unusual foreign body, and the subsequent diagnosis and treatment. Persistent ocular irritation following a corneal perforation wound, in spite of appropriate treatment, led to the presence of an intraocular foreign body being suspected. The results of radiologic examination, including CT (Siemens Somatom 2), were negative. Only A-scan sonography (Kretztechnik 7002) called attention to the possibility of a foreign body in the vitreous behind the traumatic cataract. Extracapsular extraction was immediately followed by careful removal of very small foreign-body particles from the vitreous. Once the corneal sutures had been removed the irritation decreased. The scanning electron microscope (Cambridge) images of the largest particle showed the foreign bodies to be fragments of a moth (order Noctuideae).
