Pediatric airway foreign bodies.

Foreign body aspiration (FBA) is a leading cause of accidental death in children less than one year old and is the cause of death in 7% of children less than four. Food items, especially peanuts, are the most common items aspirated in infants and toddlers, whereas older children are more likely to aspirate non-food items such as pen caps, pins, and paper clips. A high degree of suspicion is required to diagnose FBA. A history of a witnessed choking episode is most important in early diagnosis. An asymptomatic period is common after aspiration and contributes to a delay in diagnosis of greater than one week in 12% to 26% of patients. This delay in diagnosis causes increased morbidity from bronchial inflammation, obstruction, and pneumonia which is resistant to treatment. Prompt endoscopic removal of the foreign body with an open rigid bronchoscope under general anesthesia is the mainstay of therapy.

Aortoesophageal conduit due to a foreign body.

Foreign body-induced aortoesophageal conduit is a rare but frequently fatal condition. In children, ingestion of small objects can lead to such a problem, and care in eliminating small parts from the environment can lower the risk of this serious condition. This is a case report of a child who ingested a sharp, small foreign body that impacted in the esophagus and perforated the esophagus and aorta. With a hollow cylindrical shape, the foreign body provided a conduit between the aorta and esophagus, resulting in fatal massive bleeding.

Application of 3D computer-assisted techniques to sinonasal pathology--case report: war wounds of paranasal sinuses caused by metallic foreign bodies.

Foreign bodies in paranasal sinuses are found quite infrequently. They are usually detected after various types of head trauma and most commonly occur as a consequence of improper handling of firearms or explosives. In countries at war, eg, during the war in Croatia, adults and children were almost equally exposed to these injuries. The diagnosis should be based on results from precise computer tomography (CT) scanning in axial and coronal sections, and, using these data, tissues of different densities at these anatomical locations can be differentiated. The possibility of exact preoperative, noninvasive visualization of the spatial relationships of anatomic and pathologic structures with 3-dimensional (3D) computer-assisted diagnosis and intraoperative navigational techniques allows the surgeon to achieve a considerable advantage in the preoperative examination of the patient and to reduce the risk of intraoperative complications, all by the use of virtual surgery (VS) or virtual diagnosis. The expected contribution of the mentioned computer-assisted surgical technique manifests itself in defining the most appropriate mode of CT scanning of the head to design the 3D operating field model, and the possibility of active and dynamic 3D visualization of the desired anatomical regions is realized. 3D reconstruction of anatomic units becomes a routine preoperative procedure, providing a highly useful and informative visualization of the regions of interest, and, thus, advancing the definition of geometric information on anatomical contours of the 3D model by the transfer of so-called image pixel to contour pixel.

Analysis of cutaneous foreign bodies.

Foreign materials from exogenous sources pose a constant challenge to the diagnostic skills of practicing dermatologists. Depending upon circumstances, radiologic, histologic, and ultrastructural techniques can be of assistance in ascertaining the presence and nature of the substance in question. With technologic advancements, identification of small-sized particles is no longer limited to morphologic study alone. Ultrastructural analytic techniques now permit identification of minute particles or quantities of material in tissues with relative ease. No doubt, further application of currently available and newly evolving analytic systems will expand our limits of detection and enhance our scientific knowledge.

Eyelid foreign body mimics an intraocular foreign body on plain orbital radiography.

Localization of a foreign body detected on plain orbital radiography may be achieved by comparing radiographs taken with the eyes in upgaze and downgaze. Movement of the foreign body with ocular rotation is considered to indicate localization either within the globe itself or within the soft tissues of the orbit closely related to the globe. A case is reported that demonstrates that this radiologic feature may also occur when a foreign body is located within an eyelid because the position of the eyelids also changes on vertical eye movements. An eyelid foreign body may therefore mimic an intraocular foreign body on plain orbital radiography.

The improbable intravesical foreign body.

Foreign objects in the urinary bladder can occasionally pose perplexing diagnostic problems, especially in the face of a seemingly incredible history. This case illustrates the importance of investigating such claims. Occasionally, alternate diagnostic methods such as fluoroscopy or ultrasonography may assist in noninvasive diagnosis and management.

Radiographic screening for glass foreign bodies--what does a "negative" foreign body series really mean?

This study was designed to provide percentages of radiographic detection of small glass foreign bodies and to compare the detection rates (sensitivity) of two-view posteroanterior and lateral with those of four-view posteroanterior, lateral, and right and left obliques screening radiographs. Three sizes (0.5, 1.0, and 2.0 mm, maximum dimension) of beer bottle glass fragments were inserted into chicken legs and radiographed. Three staff radiologists reviewed the films independently. With two-view radiography, the 2.0-, 1.0-, and 0.5-mm glass fragments exhibited 99%, 83%, and 61% average detection rates, respectively. An analysis of variance and a Tukey's range test demonstrated that the variation in the average detection rate with respect to size was statistically significant (P less than .01). X2 Analysis failed to demonstrate a statistically significant (P greater than .05) increase in average detection rates with four-view radiography. The results of this study indicate that the size of the glass foreign body is often the limiting factor for radiographic detection and that 0.5- to 2.0-mm fragments represent a "limited detection" size range. Furthermore, two-view radiography is appropriate and more cost-effective than four-view radiography for screening purposes.

[Detection of orbital foreign bodies by CT: are plain radiographs of foreign bodies still useful?].

PURPOSE: To prove the visualisation of orbital foreign bodies by CT. MATERIALS AND METHODS: In vitro we examined defined small objects of various materials (metal, wood, glass, stone) which are common as orbital foreign bodies, Density and minimum detectable size were studied. The findings of 27 patients with suspected orbital foreign bodies were compared with the results of plain radiographs, Comberg radiographs, sonography, and surgery. RESULTS: For iron, the minimum detectable size was 0.02 mm3. A differentiation of various materials by CT was not always possible, especially in small objects. There were wide differences in density of wood (-600 HU to +130 HU) according to hardness and water content. The CT scans correctly showed number and location of foreign bodies. Other methods were inferior in detection of foreign bodies. CONCLUSION: In diagnosis of foreign body injuries of the orbit, CT is the imaging method of choice.

[Foreign body ingestion].

Foreign body ingestion is not infrequent in infants and children. The diagnosis of radiopaque foreign body ingestion does not pose a major problem. It is crucial to take an X-ray from the pharynx to the level of the pylorus. If a foreign body that might get stuck at the ileocoecal valve is ingested, it is necessary to perform a radiograph of the whole abdomen. Foreign bodies that do not pass the cardia must be extracted endoscopically. In the case of foreign bodies with a smooth contour that have passed the pylorus, parents are advised to check the child's stool or collect it and bring it for X-raying. If after a week there is no definite evidence that the foreign body has been excreted a follow-up radiograph is carried out. If the foreign body is still in the stomach or duodenum, endoscopy is necessary. The detection of nonopaque foreign bodies can be facilitated by giving oral contrast medium, making the depiction of the foreign body as a filling defect possible. As a complication, perforation can occur, the diagnosis of which may entail the use of sonography, conventional radiography and, to a lesser extent, CT.

Selective management of pediatric esophageal foreign bodies.

Esophageal foreign body is a relatively common consultation from the Pediatric Emergency Room. This study evaluates optimal selective management of esophageal foreign bodies in the pediatric patient. Eighty-six children have been referred for esophageal foreign body. Fifteen had been symptomatic for 48 or more hours before being seen. In eight, there was a known history of previous repair for esophageal atresia. In 88%, the foreign body was opaque, most frequently a coin. The most common nonopaque foreign body was retained food. Upon diagnosis, 72 children were taken to radiology, where balloon extraction under fluoroscopic control was attempted. Fourteen children went directly to the operating room for endoscopy and foreign body removal. Balloon extraction was successful in 62 cases (86%), and the children were discharged directly from the Emergency Department. The foreign body was successfully removed at esophagoscopy in the 10 cases that failed attempts at balloon extraction. Since 1990, successful extraction has been accomplished in 100% of cases (29/29). Neither balloon extraction nor endoscopy was associated with morbidity or mortality. Endoscopy was, however, associated with total hospital charges approximately 400% higher than balloon extraction. Fluoroscopically guided balloon extraction of appropriate esophageal foreign bodies is a safe and cost-effective alternative to endoscopy. Failure of nonoperative management does not complicate subsequent endoscopic removal. Patients with symptoms > 48 hours, a history of prior esophageal atresia, and/or nonopaque esophageal foreign bodies do not preclude attempt at balloon extraction.

[Orbital foreign bodies].

Orbital foreign bodies are found in a variety of instances according to the foreign body, its volume, its nature and its location. Clinical cases are variable. In an emergency, the suspicion of an orbital foreign body in case of an orbital wound is studied as well as the surgical indications for extraction of this foreign body. Later, a misdiagnosed orbital foreign body can lead to infectious complications such as cellulitis, orbital abscess, fistula, or cerebral abscess with possible mortality. The different cases are presented with their surgical indications.

Laryngotracheal foreign bodies in children. A comparison with bronchial foreign bodies.

Twenty cases of laryngotracheal foreign bodies were reviewed over an 11-year period to determine features that differentiate these from bronchial foreign bodies. A history of choking or aspiration was obtained in 18 patients (90%). The most common presenting symptoms were stridor, wheezing, sternal retractions, and cough. The chest roentgenogram was most often normal (58% [11/19]). Posteroanterior and lateral neck roentgenograms suggested the diagnosis in 92% (12/13) of the patients. The correct diagnosis was made within the first 24 hours of presentation in 11 patients (55%); 19 patients (95%) were correctly diagnosed within one week. The incidence of major complications was 45% (9/20); however, in patients with a delay in diagnosis of over 24 hours the complication rate was 67% (6/9). For this reason, in children with a diagnosis of croup or reactive airway disease who respond poorly or whose condition deteriorates despite appropriate medical therapy, early endoscopy should be considered.

Diagnostic and therapeutic approach to migrating foreign bodies.

Ingested foreign bodies are the commonest otolaryngological emergency in Singapore and other parts of Southeast Asia. One of the uncommon complications of ingested foreign bodies is migration, which has the potential to cause morbidity and mortality. A retrospective study of 24 patients presenting from 1990 to 1996 at Singapore General Hospital was done to evaluate the presentation, investigation, and diagnosis of migrated foreign bodies. Of interest, most patients had ingested foreign bodies within 24 hours. All the migrated foreign bodies were linear, sharp fish bones. Migration is said to have occurred in the presence of positive neck radiography and negative rigid esophagoscopy. Computed tomography is the investigation of choice to confirm migration. All patients had neck exploration, and factors for successful outcome are discussed. This is the largest series in the literature to date.
