Fish scale: an unusual foreign body.

Retained foreign bodies can be a source of infection and a cause of disability. A 63-year-old white man presented with a nonhealing wound of the right second finger of 1 month's duration. The injury occurred while cleaning fish. Radiographs and subsequent wound exploration showed a retained fish scale in a finger wound. In addition to foreign bodies, atypical infectious organisms must be considered in nonhealing wounds associated with fish or water.

Experimental hematogenous infection of subcutaneously implanted foreign bodies.

Implanted foreign bodies are highly susceptible to pyogenic infection. Whereas infection up to 3 months after surgery is probably due to perioperative bacterial contamination, little is known about the pathogenesis of late prosthetic infections. We employed an animal model to determine whether subcutaneously implanted foreign bodies were susceptible to experimental bacteremia. Tissue cages were implanted into guinea pigs, which were infected at the earliest 4 weeks later by intracardiac injection of Staphylococcus aureus Wood 46. The injection of 2 X 10(6) cfu did not result in any infection. Inoculation of 5 X 10(7) cfu resulted in a bacteremia of 10(2)-10(3) cfu/ml after 5 min and led to 11/26 selective tissue cage infections with no microbiological evidence of infection elsewhere. Higher inocula caused systemic infections with foci in different organs. Rifampin (7.5 mg/kg b.i.d.) was administered for 48 h, starting at different times after infection to establish the best timing for efficacious short-term therapy. When treatment was begun 1 h before or 3 h after inoculation, complete protection was observed, whereas 1/12 and 3/15 tissue cages remained infected when the first dose was not given until 24 h and 48 h, respectively, after inoculation. These experiments illustrate that implanted prostheses are highly susceptible even to bacteremias with low density of microorganisms. Prophylaxis can prevent such infections, whereas delayed short-term treatment may fail.

Unusual parotid gland foreign body.

A foreign body in the parotid gland whether from the oral cavity or through the skin is extremely uncommon. A case is described of the tip of a golden-colored pencil accidentally piercing the deep lobe after a fall. Emergency surgical removal was performed, and the diagnosis of the foreign body was quite easy. In contrast, determination of the location in the gland had to be done by a microscope, with fluoroscopy during the operation and was quite difficult. During removal, great attention was paid to avoiding facial nerve injury. This was done by identifying the facial trunk at the pointer using a microscope. The dissolved material including copper and zinc metal powder, paste, and clay, was found in the deep lobe associated with the surrounding abscess. Although these materials are assumed to be harmless to human tissues, the complete and immediate removal is to prevent salivary fistule resulting from inflammation.

Fatal aspiration pneumonia caused by an esophageal foreign body.

Esophageal foreign body accompanied by respiratory complications is a rare condition. A few cases have been reported, only two of them in adults. We describe the case of a 34-year-old mentally retarded patient who was hospitalized for aspiration pneumonia and died 48 hours after admission. At autopsy, the prominent finding was a 3 X 3-cm stone impacted into the upper esophagus and compressing the trachea from behind. The possibility of an esophageal foreign body should be included in the differential diagnosis of unexplained respiratory distress or aspiration pneumonia in adults.

Our experience in intraocular foreign-body removal.

Foreign bodies embedded in the retina and choroid that cannot be extracted by a magnet and require vitreous surgery for their removal comprise a separate group. A retrospective review of 40 consecutive cases (between 1977-1990) showed that this type of trauma frequently accompanied extensive ocular damage, including corneal and or scleral perforation, disruption of the lens, significant vitreous hemorrhage, retinal and choroid hemorrhage, and retinal detachment. Intraoperative and late complications occurred frequently, making the visual and structural outcomes of such eyes uncertain; therefore, another alternative must be sought that might improve the prognosis of these eyes. In this review, we emphasize (1) the time elapsed between the accident and the removal of the foreign body and (2) the final visual acuity and the time before the surgery.

Role of plasma and extracellular matrix proteins in the physiopathology of foreign body infections.

Foreign body implants are highly susceptible to microorganism infection. The infectious agents may be of low pathogenicity (such as S. epidermidis) or involve more virulent strains (such as S. aureus). The common denominator for the three main elements that play a role in the physiopathology of such infections (bacteria, neutrophils, and different biomaterials) are host proteins deposited over the surface of the devices immediately after their implantation. These proteins modulate that host cells response but can also promote Staphylococcus adhesion to the biomaterial. Neutrophils and other cells such as fibroblasts adhere to several extracellular matrix proteins such as fibronectin, fibrinogen, collagen, vitronectin, via specific cell surface receptor. The evolution of the technology and the increasing numbers of long-term artificial implants require a better understanding of fundamental mechanisms of foreign body infections to reduce their incidence and optimize their treatment.

Report on a child with stricture following foreign body of long duration in the bronchus. Discussion on the management of bronchial foreign bodies.

A case report and the management of a 10-year-old girl who had inhaled a foreign body into the right intermediate bronchus at some unknown (but certainly not recent) time previously is given. A stricture at the site of the impaction of the foreign body was found. The excision of the stricture and repair of the bronchus with pericardium is described together with a 3-year follow-up report. The diagnosis and immediate management of foreign bodies in the bronchus are discussed and the importance of differentiating organic and non-organic foreign bodies is stressed. The management of bronchial strictures is discussed as is the result obtained in the above reported case.

Gunshot wound of the chest with five intrathoracic foreign bodies.

When a firearm projectile strikes an intermediate target before entering a body, foreign material from that target may be carried into the body with the projectile. This material should be sought and recovered at autopsy, for it may prove to be valuable evidence in subsequent legal proceedings. The unusual case reported here is that of a 12-year-old boy who was sitting on a couch in front of his living room window and there sustained a .45 caliber gunshot wound of the left anterior chest from a gunshot fired at another person in the street outside. First passing through the back of the couch, the bullet carried with it into the body four pieces of cloth and a metal spring, thereby causing an unusual cutaneous entrance wound, and laceration of the right cardiac ventricle and fatal cardiac tamponade within an intact pericardial sac. The assailant was convicted of first-degree murder, a verdict which he appealed.

Percutaneous retrieval of nonvascular foreign bodies.

Although intravascular foreign bodies are routinely removed with percutaneous extraction, surgical retrieval is performed of most nonvascular foreign bodies. The authors describe six cases in which percutaneous extraction was performed for removal of nonvascular foreign bodies. These foreign bodies included an intraabdominal laparotomy towel, two pelvic drains, an angiographic guidewire fragment in a pelvic abscess cavity, and a superficially located sewing needle and bullet fragment. Computed tomography or plain radiography was performed to define the safest track for percutaneous removal. Fluoroscopy was performed to direct foreign body removal; the major challenge of the procedure was precise localization of the foreign body to minimize dissection. Although a surgeon and operating suite were available for backup care if necessary, all six foreign bodies were removed successfully without complication by the interventional radiologist in the radiology suite. Percutaneous retrieval of nonvascular foreign bodies, while not frequently performed, can in many cases obviate surgical incisions, extensive dissection, and the cost and risk of administration of general anesthesia.

[Statistical analysis of tracheobronchial foreign bodies].

Incidence of foreign body aspiration in tracheobronchial tree is rare, however the foreign body aspiration can lead to severe illness and even death if not diagnosed and treated promptly. We retrospectively analyzed forty five patients who underwent ventilation bronchoscope under general anesthesia for suspected aspirated foreign bodies in our hospital. In thirty eight patients, foreign body was confirmed in tracheobronchial tree, while in seven patients foreign body was not confirmed with bronchoscope. The thirty eight patients ranged in age from 10 months to 73 years; the peak incidence of foreign body aspiration occurred in children under 3 years of age. Twenty five of thirty eight patients were male. Food or food derivatives were the causative agents in 68% of the patients, with 65% due to a portion of peanut. The foreign body was located in the right and left bronchus with almost equal frequency. The main symptoms were coughing (72%), wheezing (53%), and dyspnea (25%). The radiographic abnormality was seen in eighteen of thirty eight patients. A radio-opaque material was seen in 18%. Children at age 6 years of younger (90%) had been witnessed to choke on identifiable foreign body, but only 40% were diagnosed within 24 hours. Twelve of these children were treated unnecessarily for asthma, pneumonia, or so on. We conclude that it is most important to take history carefully considering the possibility of foreign body aspiration in the patients with coughing, wheezing, or dyspnea.

Foreign body gingivitis: identification of the foreign material by energy-dispersive x-ray microanalysis.

Foreign bodies identified in 61 cases of foreign body gingivitis were analyzed by energy-dispersive x-ray microanalysis. This was compared with the energy-dispersive x-ray microanalysis of 62 dental materials. Comparative analysis indicated most foreign bodies were of dental material origin, usually abrasives. It is suggested that they are factitially and iatrogenically introduced during a variety of self-administered and professionally performed dental hygiene and restorative procedures. Individual elements, and elements by class, were correlated with previously described clinical and microscopic features of the cases. There was no association between any microscopic or clinical attribute of FBG and the presence of allergenic or cytotoxic elements. It is postulated that the physical presence of foreign bodies may be sufficient for the development of foreign body gingivitis. Dentists should be aware of the potential for chronic tissue damage that can result from the unguarded use of abrasive material next to the gingiva.
