    1999-01-01

    We present two types of "new" foreign body granulomas caused by the injectable aesthetic microimplants Bioplastique and Artecoll. We report the clinical and histopathologic findings in five patients who had undergone treatment of mainly facial contour abnormalities with one of these implants. All patients were women, and the mean age was 45 years (age range 24-72 years). Two patients presented after treatment with Bioplastique; in three patients, augmentation was achieved by using Artecoll. Unsatisfactory cosmetic effects led to excision of the implants in four patients; in one patient, parts of the implant were excised during another cosmetic intervention. Subsequent histopathologic examination showed features of foreign body granulomas with distinctive cystic spaces. The clue to the diagnosis is the particular configuration of these cystic spaces and the characteristic shape of the foreign bodies. Bioplastique granuloma presents with irregularly shaped cystic spaces of varying size containing jagged, translucent, nonbirefringent foreign bodies whereas Artecoll granuloma shows numerous round vacuoles nearly identical in size and shape enclosing round and sharply circumscribed, translucent, nonbirefringent foreign bodies. These specific histopathologic findings unequivocally allow the correct diagnosis in spite of sparse clinical information. PMID:9888711

    A 19-year-old man presented with phimosis and painful swelling of the penis four weeks after augmentation with silicone in Thailand. Histology revealed a foreign body reaction to silicone. Infectious causes were ruled out. Granulomatous foreign body reactions to silicone are common, but there are few case reports on reactions following silicone injection for penis enlargement. Foreign body reactions should be included in the differential diagnosis of penis swelling. PMID:20337774

    A large list of foreign substances may penetrate the skin and induce a foreign body granulomatous reaction. These particles can enter the skin by voluntary reasons or be caused by accidental inclusion of external substances secondary to cutaneous trauma. In these cases, foreign body granulomas are formed around such disparate substances as starch, cactus bristles, wood splinters, suture material, pencil lead, artificial hair, or insect mouthparts. The purpose of this article is to update dermatologists, pathologists, and other physicians on the most recent etiopathogenesis, clinical presentations, systemic associations, evaluation, and evidence-based management concerning foreign body granulomatous reactions of skin.

    Gastrointestinal and bronchial foreign bodies may cause significant clinical complications with a high degree of morbidity. In adults, a large variety of foreign bodies are accidentally or intentionally ingested, inserted or aspirated. In the majority of cases, the objects are expelled conservatively by coughing, vomiting or bowel movements. The risk for obstruction, perforation and penetration depends upon the type of object, those with sharp edges or tips having the highest risk. In these situations, the objects have to be removed by an endoscopic or an operative intervention. We present four foreign body stories including a young lady who swallowed a pen during sleep, a farmer who inserted a corncob into the rectum because of intractable diarrhoea, an elderly gentleman who aspirated a dental bridge while laughing and a cocain body packer who was caught at the border. Back ground, complications and removal procedures of the four cases are discussed. PMID:19048523

    There are many circumstances in which the diagnosis of endobronchial inhalation of a foreign body (FB) can be missed. Generally, in such cases, within weeks or at most months from the event, clinical bronchopulmonary symptoms develop which allow a correct diagnosis to be made and significant complications to be avoided. We report the case of a patient in whom an endobronchial FB remained undiagnosed, because of lack of symptoms, for almost three years, and then caused signifiicant complications before being identified and removed. Problems related to diagnosis and therapy are discussed. PMID:18493510

    Aim: Foreign bodies ingested by the oral route enter into the gastrointestinal tract and are considered a significant health problem in the childhood. In this study, we evaluated the pediatric patients who presented to our hospital with the complaint of ingestion of foreign body. Material and Methods: The hospital records of all children who presented to our clinic because of ingestion of foreign body between January 2008 and January 2015 were examined retrospectively. The complaints at admission, the types of foreign bodies ingested, the localization of the foreign body in the gastrointestinal tract and the approaches and treatment methods used were examined. Results: Thirty-six (56%) of 64 patients included in the study were male and 28 (44%) were female and the mean age was 5.7±4.6 years (10 months–17 years). Thirty eight (59%) of 64 children who were included in the assessment were below the age of five years. The most common complaint at presentation was parental recognition of the ingested object and dysphagia. The most commonly ingested foreign bodies included coins, sewing pins, safety pins and hairclips. Nail clipper detected in the stomach, sewing pin which penetrated through the duodenal wall and stuck to hepatic parenchyma were the first pediatric cases in the literature. Upper esophagus was the most common location for foreign bodies. Endoscopic examinations were performed in 55 of 64 children. Conclusions: Early detection and treatment of ingested foreign bodies in the upper gastrointestinal system is important in terms of preventing possible complications. In our study, the most frequent foreign bodies detected in the upper digestive tract were coins and they were most frequently detected in the upper esophagus. Most of our patients were below the age of five years. Flexible endoscopic method was used commonly for treatment. PMID:26884693

    2008-01-01

    The foreign body reaction composed of macrophages and foreign body giant cells is the end-stage response of the inflammatory and wound healing responses following implantation of a medical device, prosthesis, or biomaterial. A brief, focused overview of events leading to the foreign body reaction is presented. The major focus of this review is on factors that modulate the interaction of macrophages and foreign body giant cells on synthetic surfaces where the chemical, physical, and morphological characteristics of the synthetic surface are considered to play a role in modulating cellular events. These events in the foreign body reaction include protein adsorption, monocyte/macrophage adhesion, macrophage fusion to form foreign body giant cells, consequences of the foreign body response on biomaterials, and cross-talk between macrophages/foreign body giant cells and inflammatory/wound healing cells. Biomaterial surface properties play an important role in modulating the foreign body reaction in the first two to four weeks following implantation of a medical device, even though the foreign body reaction at the tissue/material interface is present for the in vivo lifetime of the medical device. An understanding of the foreign body reaction is important as the foreign body reaction may impact the biocompatibility (safety) of the medical device, prosthesis, or implanted biomaterial and may significantly impact short- and long-term tissue responses with tissue-engineered constructs containing proteins, cells, and other biological components for use in tissue engineering and regenerative medicine. Our perspective has been on the inflammatory and wound healing response to implanted materials, devices, and tissue-engineered constructs. The incorporation of biological components of allogeneic or xenogeneic origin as well as stem cells into tissue-engineered or regenerative approaches opens up a myriad of other challenges.

    We report two cases of unusual and undeclared oesophageal foreign bodies. A small double-rounded calabash or bottle gourd Lagenaria siceraria, stuffed with traditional medicine designed to acquire spiritual power. A whole tricotyledonous kola nut Cola nitida also designed to make medicine to gain love from a woman after passing it out in stool. Each case presented with a sudden onset of total dysphagia and history of ingestion of foreign bodies was not volunteered by any despite direct questioning. Plain radiograph of the neck and chest in either case did not reveal presence of foreign body. Both were successfully removed through rigid oesophagoscopy. PMID:22718184

  12. Management of rectal foreign bodies

    2013-01-01

    Background Entrapped anorectal foreign bodies are being encountered more frequently in clinical practice. Although entrapped foreign bodies are most often related to sexual behavior, they can also result from ingestion or sexual assault. Methods Between 1999 and 2009, 15 patients with foreign bodies in the rectum were diagnosed and treated, at Izmir Training and Research Hospital, in Izmir. Information regarding the foreign body, clinical presentation, treatment strategies, and outcomes were documented. We retrospectively reviewed the medical records of these unusual patients. Results All patients were males, and their mean age was 48 years (range, 33–68 years). The objects in the rectum of these 15 patients were an impulse body spray can (4 patients), a bottle (4 patients), a dildo (2 patient), an eggplant (1 patient), a brush (1 patient), a tea glass (1 patient), a ball point pen (1 patient) and a wishbone (1 patient, after oral ingestion). Twelve objects were removed transanally by anal dilatation under general anesthesia. Three patients required laparotomy. Routine rectosigmoidoscopic examination was performed after removal. One patient had perforation of the rectosigmoid and 4 had lacerations of the mucosa. None of the patients died. Conclusions Foreign bodies in the rectum should be managed in a well-organized manner. The diagnosis is confirmed by plain abdominal radiographs and rectal examination. Manual extraction without anaesthesia is only possible for very low-lying objects. Patients with high- lying foreign bodies generally require general anaesthesia to achieve complete relaxation of the anal sphincters to facilitate extraction. Open surgery should be reserved only for patients with perforation, peritonitis, or impaction of the foreign body. PMID:23497492

    Foreign bodies usually do not cause complications and pass through the gastrointestinal tract spontaneously. Usually endoscopic intervention is recommended within 24 hours. Cases of acute appendicitis caused by foreign bodies are very rare. In our case, we experienced successful endoscopic and surgical treatment of a patient with ingestion of razor blade and some unrecognizable foreign bodies. A 22-year-old soldier was admitted with a small quantity of hematemesis and epigastric pain. We performed emergent endoscopy and successfully removed several foreign bodies. After 17 days, we performed appendectomy to remove the remaining foreign body and to relieve the symptoms. There is no doubt that endoscopic intervention is definitely useful method to remove foreign bodies. If there is no spontaneous drainage of the foreign body from the appendix, an appendectomy must be considered to remove the foreign body and prevent surgical complications such as appendicitis, periappendiceal abscess, and perforation.

    Craniospinal penetrating foreign body (FB) injuries are interesting, but rarely observed, cases. They are important in terms of the complications that they may cause. The etiologies of craniospinal penetrating injuries and intracranial FB are also different. Though a sewing needle is more rarely seen in an intracranial FB, it may occur as atttempted infanticide or as a result of an accident especially in early childhood before the closure of fontanels. We detected an intracranial sewing needle in the head radiograph of a case admitted to the emergency department for another reason. We present this case since this is a rare injury and the etiologies of craniospinal penetrating foreign body have different characteristics. PMID:25255596

    Esophageal and aspirated foreign bodies have important clinical significance, and both should be considered carefully when the history or physical examination findings raise sufficient suspicion. The published evidence regarding the diagnosis and management of foreign body ingestion or aspiration is weighted disproportionately with observational studies, case controls, expert opinion, and systematic reviews. Most of the publications would receive a categorization of C (observational studies including case-control and cohort design) and D (expert opinion, case reports, and clinical reasoning). One of the few prospective studies examining the diagnostic evaluation of foreign body aspiration in children could be considered level B evidence (randomized clinical trials, systematic reviews, or diagnostic studies with minor limitations). This study found that the medical history is the most important predictive part of the evaluation. There is evidence for considering bronchoscopy if there is significant history suggestive of foreign body aspiration, even in the setting of normal physical examination findings. (28). Most ingested foreign bodies spontaneously pass without incident. However, special attention should be paid to objects in the esophagus as well as to batteries and magnets. Based on a systematic review of the literature (level B evidence) and the potential for rapid and life-threatening damage, batteries in the esophagus should be removed immediately. (10) Other objects, such as coins, may be observed for passage in an asymptomatic patient. In addition, given the high risk of significant complications, ingestion of high-powered magnets should be quickly and carefully evaluated. Although single magnets are likely to pass without complication, multiple magnets or magnets ingested with other metal objects can cause significant damage and should be removed if there is any concern for mural entrapment, bowel perforation, or failure to progress.

    The presence of foreign biological substances in the human body can lead to violent immune reactions. This is the report of a very rare case involving not only the presence of a biological substance, but also a symbiotic relationship between a living plant (the common wheat grain, Triticum aestivum L.) and the human body. Black coal particles and one cereal grain were removed from the subgalea of the right parietal region of a 35-year-old man who had sustained injuries in a motor vehicle accident 16 days earlier. There were signs of germination of the grain, but no macroscopic or microscopic evidence of an inflammatory reaction. Grain germination was verified microscopically. There are various explanations for the absence of an immune reaction, but only coal-tar-induced immunosuppression can explain the observed phenomenon.

    Fish bone foreign body (FFB) is the most frequent food-associated foreign body (FB) in adults, especially in Asia, versus meat in Western countries. The esophageal sphincter is the most common lodging site. Esophageal FB disease tends to occur more frequently in men than in women. The first diagnostic method is laryngoscopic examination. Because simple radiography of the neck has low sensitivity, if perforation or severe complications requiring surgery are expected, computed tomography should be used. The risk factors associated with poor prognosis are long time lapse after FB involvement, bone type, and longer FB (>3 cm). Bleeding and perforation are more common in FFB disease than in other FB diseases. Esophageal FB disease requires urgent treatment within 24 hours. However, FFB disease needs emergent treatment, preferably within 2 hours, and definitely within 6 hours. Esophageal FFB disease usually occurs at the physiological stricture of the esophagus. The aortic arch eminence is the second physiological stricture. If the FB penetrates the esophageal wall, a life-threatening aortoesophageal fistula can develop. Therefore, it is better to consult a thoracic surgeon prior to endoscopic removal. PMID:27461891

    One of the leading causes of medical malpractice claims in emergency medicine is the misdiagnosis of the presence of foreign bodies. Radiolucent foreign bodies are especially difficult to differentiate from surrounding soft tissue, gas, and bone. Current imaging modalities employed for the detection of foreign bodies include: X-ray computed tomography, magnetic resonance, and ultrasound; however, there is no consensus as to which modality is optimal for diagnosis. Because many radiolucent foreign bodies have sufficient contrast for imaging in the optical domain, we are exploring the use of laser-induced optoacoustic imaging for the detection of foreign bodies, especially in craniofacial injuries, in which the foreign bodies are likely to lie within the penetration depth of visible and near infrared wavelengths. Tissue-simulating phantoms containing various common foreign bodies have been constructed. Images of these phantoms have been successfully generated using two laser-based optoacoustic imaging methods with different detection modalities. In order to enhance the image contrast, common foreign bodies are being scanned over a wide range of wavelengths to obtain the spectroscopic properties of the materials commonly associated with these foreign bodies. This spectroscopic characterization will help select specific wavelengths to be used for imaging specific objects and provide useful diagnostic data about the material properties of the object.

    Most ingested foreign bodies pass through the gastrointestinal tract without any incident. However, foreign bodies lodged in the appendix can cause an inflammatory reaction with or without perforation. Here, we present a case of a 54-year-old woman with perforated appendicitis who consumed wild game containing a shot pellet. Five months before admission, she had eaten the meat of a pheasant that had been shot with a shotgun. Abdominal computed tomography confirmed the diagnosis of perforated appendicitis with abscess due to a foreign body. Subsequently, a laparoscopic appendectomy was performed. Follow-up radiographs obtained after the surgery did not identify the foreign body. Histolopathologic examination confirmed appendiceal perforation with focal inflammation secondary to a foreign body. PMID:22487649

    We conducted a descriptive study of 524 patients who had been suspected of having aspirated a foreign body and who had been evaluated at one of two major hospitals in Jordan from January 1993 through December 2003. A tracheobronchial foreign body was found in 386 of these patients (73.7%). Most of them (66.8%) were younger than 2 years, and the male-to-female ratio was 3 to 2. The mean duration between aspiration and diagnosis was 48 hours. The most common presenting symptoms were cough (90.4% of foreign-body-positive patients), diminished air entry (66.8%), and dyspnea (65.0%). The most frequently aspirated objects were seeds (35.4%), particularly watermelon seeds, nuts (26.8%), and vegetables (25.3%). The most common site of foreign-body impaction was the right bronchus (60.9%). Rigid bronchoscopy was used to remove the foreign body in all cases. The complication rate was 3.4%. Our experience with aspirated tracheobronchial foreign bodies in Jordan was not substantially different from that reported in other countries. The only difference was that the most frequently aspirated foreign body in our study was seeds. PMID:17385621

    Foreign body aspiration can occur in any age group, but it is more commonly seen in children. In adults, there is usually a predisposing condition that poses a risk of aspiration. If aspiration occurs, prompt diagnosis and extraction of the foreign body is needed to prevent early and late complications. We report a rare case of neglected foreign body aspiration in a 45-year-old schizophrenic opium addicted patient, which resulted in an occlusive lesion in the bronchus, mimicking bronchial carcinoma.

    As endovascular therapies increase in frequency, the incidence of lost or embolized foreign bodies is increasing. The presence of an intravascular foreign body (IFB) is well recognized to have the potential to cause serious complications. IFB can embolize and impact critical sites such as the heart, with subsequent significant morbidity or mortality. Intravascular foreign bodies most commonly result from embolized central line fragments, but they can originate from many sources, both iatrogenic and noniatrogenic. The percutaneous approach in removing an IFB is widely perceived as the best way to retrieve endovascular foreign bodies. This minimally invasive approach has a high success rate with a low associated morbidity, and it avoids the complications related to open surgical approaches. We examined the characteristics, causes, and incidence of endovascular embolizations and reviewed the various described techniques that have been used to facilitate subsequent explantation of such materials.

    190 patients presenting intraocular foreign bodies, hospitalized between 1981-1991, are examined. The study of accidents: cases showed a clear prevalence of work accidents--127 cases (66.84%); 86 of these cases occurred in industry (45.26%), the rest of 41 occurred in agriculture (21.58%). The professions most exposed to such accidents are those of locksmith, mechanic in agriculture or automobile industry. The postsurgical evolution and the incidence of complications show that intraocular foreign bodies are wosse-making factors of ocular plagues, because of anatomical structures disorganization, transparency modifications and infectious complications implied, which determined the diminishing of visual acuity in 88.08% of cases. The big percentage of work accidents in the etiology of intraocular foreign bodies emphasize the great importance of foreign the work-protection rules (regarding a especially the wearing of protection glasses) and of introducing of automation in technological processes involving great risks.

After standing in close proximity to a construction worker breaking a tile, a 26-year-old woman using soft contact lens for the correction of mild myopia presented to emergency department for evaluation of a foreign body sensation of her right eye. Methods and Results. Diagnosis was confirmed by gonioscopic examination and a noncontrast CT scan of head and orbits. The foreign body was removed by an external approach without utilizing a magnet. The patient's final outcome was favorable. Discussion. The above is a rare clinical situation, which is impossible to detect on slit-lamp examination without a gonioscopic view. Proper imaging and a specific management are mandatory in order to achieve favorable outcome. PMID:23091762

    Foreign body synovitis in the Pacific region typically involves a penetrating injury to a joint. The introduced biomaterial produces an inflammatory reaction or innoculates the tissue with bacteria, creating an infection. Each year millions of people visit the Hawaiian Islands to hike, surf, snorkel, and participate in other outdoor activities, creating an array of interactions between people and nature. The two most commonly reported penetrating foreign body joint injuries are sea urchin synovitis and synovitis due to implantation of organic material such as wood splinters or plant thorns.

    A 12-year-old child had left orbital trauma by wood. He consulted 4 months after for orbital cellulitis with cutaneous fistula. The CT scan showed the presence of a left orbital wood foreign body extended to the homolateral cavernous sinus and intracranial. Extraction of the wood fragment associated with an adapted antibiotic treatment led to clinical improvement without visual recovery. A situation of orbital trauma and secondary orbital inflammatory syndrome must raise the suspicion of a foreign body of the orbit and motivate emergency imaging for optimal management of the disorder.

    2015-01-01

    Subcutaneously implanted materials trigger the host's innate immune system, resulting in the foreign body reaction. This reaction consists of protein adsorption on the implant surface, inflammatory cell infiltration, macrophage fusion into foreign body giant cells, fibroblast activation and ultimately fibrous encapsulation. This series of events may affect the function of subcutaneous implants, such as inhibition of drug diffusion from long-acting drug delivery depots and medical device failure. The foreign body reaction is a complex phenomenon and is not yet fully understood; ongoing research studies aim to elucidate the cellular and molecular dynamics involved. Recent studies have revealed information about the specific role of macrophages and their differential activation towards pro- and anti-inflammatory states, as well as species differences in the timing of collagen deposition and fibrosis. Understanding of the diverse processes involved in the foreign body reaction has led to multiple approaches towards its negation. Delivery of tissue response modifiers, such as corticosteroids, NSAIDs, antifibrotic agents, and siRNAs, has been used to prevent or minimize fibrosis. Of these, delivery of dexamethasone throughout the implantation period is the most common method to prevent inflammation and fibrosis. More recent approaches employ surface modifications to minimize protein adsorption to 'ultra-low' levels and reduce fibrosis. However, the diverse nature of the processes involved in the foreign body reaction favor the use of corticosteroids due to their wide spectrum action compared to other approaches. To date, combination approaches, such as hydrophilic coatings that reduce protein adsorption combined with delivery of dexamethasone are the most effective. PMID:26306445

    Biodegradable poly-(DL-lactide-co-glycolide) (PLGA) microspheres (MSP) are attractive candidate vehicles for site-specific or systemic sustained release of therapeutic compounds. This release may be altered by the host's foreign body reaction (FBR), which is dependent on the characteristics of the implant, e.g. chemistry, shape or size. In this study, we focused on the characterisation of the influence of MSP size on the FBR. To this end we injected monodisperse MSP of defined size (small 5.8 µm, coefficient of variance (CV) 14 % and large 29.8 µm, CV 4 %) and polydisperse MSP (average diameter 34.1 µm, CV 51 %) under the skin of rats. MSP implants were retrieved at day 7, 14 and 28 after transplantation. The FBR was studied in terms of macrophage infiltration, implant encapsulation, vascularisation and extracellular matrix deposition. Although PLGA MSP of all different sizes demonstrated excellent in vitro and in vivo biocompatibility, significant differences were found in the characteristics of the FBR. Small MSP were phagocytosed, while large MSP were not. Large MSP occasionally elicited giant cell formation, which was not observed after implantation of small MSP. Cellular and macrophage influx and collagen deposition were increased in small MSP implants compared to large MSP. We conclude that the MSP size influences the FBR and thus might influence clinical outcome when using MSP as a drug delivery device. We propose that a rational choice of MSP size can aid in optimising the therapeutic efficacy of microsphere-based therapies in vivo. PMID:25350249

    This paper reports the results of analysis of the treatment of 8 children after the removal a disk battery from the nasal cavity. It was shown that the restoration of all the structures of the nasal cavity is possible if the foreign body remains in it during a short (up to 5 hours) time. The longer presence of such a body in the nasal cavity gives rise to post-traumatic defects, in the first place septal perforations and injuries to the inferior turbinated bone. In such cases, the foreign body must be immediately removed from the nasal cavity, and the child should be placed under thorough medical observation taking into consideration the long process of rejection of necrotic tissues and healing of the resulting defects.

    Two cases of swallowing of foreign material related to dental implants during dental practice are described. A conservative approach by clinical-radiographic follow-up was performed in both cases; however, one of the patients required colonoscopy under general anesthesia for the removal of the impacted foreign body from the intestinal region. These complications not only have associated economic cost but also carry the risk of malpractice litigation against the professional; thus, the surgeon was responsible for all the costs of hospital and surgery management of this case. Details of the clinical signs, radiographic examinations, type of treatment, and follow-up are presented. PMID:22446442

    The typical chest computed tomography (CT) finding of the arc welders is ill-defined micronodules diffusely distributed in the lung. We report a rare case of tracheobronchial foreign body in welder without the history of allotriophagy and foreign body aspiration. We used the CT and mineralogical analysis in diagnosis and the flexible fiberoptic bronchoscope in therapy. The CT showed bronchiectasis with pulmonary infiltration of the right lower lobe and high-density shadow in the basal bronchus of the right lower lobe. The foreign bodies were removed by a fibreoptic bronchoscope. Semiquantitative chemical analyses showed that the constituent of foreign body was similar to the dregs which were collected in the same garage. This is an unusual case of the welding-related respiratory diseases, which is different from Welder's siderosis and broncholith. PMID:25619320

    Prevention and early recognition remain critical factors in the treatment of foreign body inhalation in children. Accidental inhalation of both organic and nonorganic foreign body material continues to be a cause of childhood morbidity and mortality. The University of North Carolina Department of Otolaryngology has collected foreign bodies acquired from the airways of young children since its inception in 1954. The authors reviewed 26 foreign bodies removed bronchoscopically from the airways of children during the years 1955 to 1960, and compared these to 27 foreign bodies collected from 1999 to 2003. Findings showed remarkable similarities in the types of foreign bodies aspirated. Organic foreign bodies were most commonly found. Differences existed in the type of organic foreign body aspirated, with popcorn being retrieved in 15% of cases during the later time period. Also, an increase in bronchoscopically removed small toy parts was found in the later group. PMID:15180015

    Infections play a major role in the practice of ENT. Microbial penetration into tissues of the head and neck can initiate a focal reaction causing superficial self-resolving infections. However, some of these have the potential to develop into life-threatening disease. We provide an overview of the most common ENT infections with focus on the presentation, diagnosis and management. Foreign bodies of the ear, nose and throat are a common presentation to primary and emergency care. Most commonly these are seen in children and include plastic toys, beads and foodstuffs inserted into the ears and nose. Diagnosis is often delayed as insertion is usually not witnessed. In exceptional cases airway foreign bodies can present as a life-threatening emergency. Removal of foreign bodies can usually be achieved by a skilled practitioner with minimal complications. Methods of removal include suction catheters, syringing, and use of instrumentation. In adults, the treatment of oesophageal food bolus obstruction may require a combination of medical and surgical intervention. PMID:27057069

    We report two cases in which intrabronchial foreign bodies were removed with a fiberoptic bronchoscope. In both cases the foreign body was a seed of a small Japanese apricot. Atelectasis or obstructive pneumonia was seen on chest roentgenograms. The foreign bodies were associated with slight inflammation and polyps on the bronchial epithelium. The foreign bodies were removed by applying suction with a fiberoptic bronchoscope. This method may also be useful for removing other large, hard, uneven, and ball-like foreign bodies. PMID:9212671

    Insults from corneal foreigh bodies range from trivial windblown debris through destructive chemicals, penetrating wounds, and severe secondary infection. History and preliminary examination should begin concurrently, particularly in the case of chemically active compounds. Needed auxiliaries are topical anesthetics, oblique light, magnification, sterile sodium fluorescein for diagnostic staining of surface breaks, removal instruments, and topical antibiotics to reduce the potential of secondary infection. A steadied, seated position for the physician, resting posture with hands supported on the face, and an oblique approach tend to reduce the likelihood of unwanted perforations or scars. An irrigating stream of sterile saline delivered through a 25 gauge short needle on a 5 cc syringe will dislodge most recent foreign bodies. The sterile needle is also available as a spud. Corneal thickness varies from slightly above 1 mm in the periphery to less than 0.5 mm centrally. Therefore, it is essential to have clear visualization of the foreign body in relation to corneal depth. Dislodgment into the anterior chamber or incidental perforation of the cornea generally require hospitalization, intensive antibiotics, and steroid therapy. PMID:1206368

The clinical course of a corneal epithelial defect can range from a relatively benign self-healing abrasion to a potentially sight-threatening complication such as a corneal ulcer, recurrent erosion, or traumatic iritis. A detailed clinical history regarding risk factors and exposure, along with a thorough slit lamp examination with fluorescein dye are essential for proper diagnosis and treatment, as well as to rule out penetrating globe injuries. Referral to an ophthalmologist is recommended in difficult cases or if other injuries are suspected. PMID:26319343

    Abstract Background: Occult bronchial foreign body can be very difficult to diagnose early in an adult patient without acute symptoms. This report describes a rare case of undetected Chinese medicine “Coptis chinensis” aspiration for 10 long years. Methods: A case was reported that a female patient complained of a 10-year history of productive cough. A battery of tests were given to confirm the diagnosis. Results: Chest computed tomography (CT) showed extensive bronchiectasis and multiple nodules, along with stenosis of left lower lobar bronchus. An extensive solid lesion with surrounding inflammatory granulation tissue was seen on her first bronchoscopy and biopsy revealed chronic mucosal inflammation. A neglected history of Coptis chinensis regularly kept in-mouth while sleeping for the last 10 years in this patient provided clues for a final diagnosis. Confirmatory diagnosis of bilateral tracheobronchial foreign bodies caused by recurrent inhalation of Coptis chinensis was made by a second bronchoscopy. Conclusions: This case clearly demonstrates that a precise medical history is often overlooked. A high index of suspicion, a precise medical history, radiographic features of chronic respiratory symptoms not explained by other conditions were keys to diagnosing this case. PMID:27495017

    Background: Implantable biosensors for continuous glucose monitoring can greatly improve diabetes management. However, their applications are still associated with some challenges and one of these is the gradual functionality loss postimplantation as a consequence of the foreign body response (FBR). Sensor miniaturization in combination with drug-eluting biocompatible coatings is a promising strategy to enhance in vivo performance. However, limited study has been performed to understand the effect of initial trauma and implant size on foreign body reaction as well as in vivo performance of implantable glucose sensors. Methods: Different initial trauma was induced by implanting composite coated dummy sensors into rats using various sized needles and 3 different-sized dummy sensors were implanted to examine the size effect. Histological evaluation was performed to relate the inflammatory cell counts and foreign body capsule thickness with the implantation needle size and sensor size respectively. The effect of biocompatible coating on the performance of implantable glucose sensors was determined using both coated amperometric glucose sensors and microdialysis probes. Results: The results revealed that the degree of acute inflammation was mainly controlled by the extent of the initial trauma: the greater the trauma, the greater the acute inflammatory response. Implant size did not affect the acute inflammatory phase. However, the extent of chronic inflammation and fibrous encapsulation were affected by sensor size: the smaller the size the less the extent of chronic inflammation and fibrous encapsulation. Glucose sensors implanted using 14 gauge needles showed significantly lower initial in vivo response compared to those implanted using 16 gauge needles. This was not observed for sensors with dexamethasone-eluting biocompatible coatings since inflammation was suppressed. Conclusions: The results of the current study indicate that the extent of the inflammatory

    A foreign body in heart is rare, but it is more frequently encountered than the past as iatrogenic causes are increasing. Clinicians should be aware that foreign body could be mistaken for normal structure of heart. In order for accurate diagnosis, multi-imaging modalities should be used for information of exact location, mobility and hemodynamic effects. A decision to intervene should be made based on potential harms harbored by foreign bodies. Endovascular retrieval should be considered as an option. However, when fatal complications occur or when foreign bodies are embedded deeply, a surgical removal should be attempted. PMID:25837198

    Foreign body aspiration can be a life-threatening emergency. An aspirated solid or semi-solid object may lodge in the larynx, trachea or other breathing airways. If the object is large enough to cause nearly complete obstruction of the airway, asphyxia may rapidly cause death. We report a 19-year old man admitted with right lower lobe pneumonia who spontaneously expelled a foreign body, one day after admission and glucocorticoids administration. Glucocorticoids should be considered in foreign body aspiration management because improvement of the inflammatory reaction may facilitate expontaneous expulsion or foreign body extraction PMID:26742192

    AIM: To study a retrospective analysis of patients who presented to the emergency departments (ED) with complaints related to foreign body ingestions. METHODS: Patients older than 16 years of age who presented to the ED between January 1st and December 31st of 2010 with complaints related to swallowed foreign bodies were identified from electronic health records and patient charts. RESULTS: A total of 100 patients presented with a complaint of foreign body ingestion during the study period. Overall, an X-ray was performed on 75 patients, and a fiberoptic evaluation was performed on 45 patients. A foreign body was detected in 46 (46%) patients. The diagnostic yield of the X-ray was 27 (36%) out of 75 patients, while the diagnostic yield of the fiberoptic evaluations was 21 (47%) out of 45 patients. The detected foreign bodies were mostly located in the esophagus (17 out of 46 foreign bodies detected). When the types of ingested foreign bodies were evaluated, 52 (52%) patients reported ingesting food, and 19 (19%) patients reported swallowing pins. An X-ray was performed on 33 patients with accidental food ingestions but yielded a positive result in only two cases. In 12 out of 21 patients with accidental food ingestion who underwent fiberoptic evaluation, the foreign material was detected and removed. CONCLUSION: Plain radiography is helpful in the localization of radiopaque swollen foreign bodies, while fiberoptic methods are useful as both diagnostic and therapeutic tools, regardless of radiopacity.

    The presence of a foreign body in the periapical tissues can cause endodontic failure by triggering an inflammatory response and a subsequent foreign body reaction. This inflammatory response, which can occur to varying degrees, appears radiographically as a radiolucency that can remain asymptomatic for many years. A foreign object can reach the apical region by accident or iatrogenic procedures during dental procedures. The aim of the present case report is to describe the endodontic surgical treatment of an iatrogenic displacement of a foreign body (a metal fragment) into the periapical tissues and to describe its clinical and radiographic follow-up over a period of 52 months.

The mean age of the patients was 49 years. The commonest foreign bodies were food particles and the most common symptom was acute dysphagia. The most frequent localization of impaction was the cricopharyngeal sphincter (Killian's mouth). In 89% of the cases the foreign body could be removed endoscopically. The most common underlying pathology was hiatal hernia. There were severe complications related to the presence of the foreign body in 4.5% of the cases; one death was due to aorto-esophageal fistula. Foreign bodies, mainly impacted food particles (p less than 0.001), are most frequent in patients over 65, mainly females (p less than 0.01). PMID:2390340

    Aquamid represents a new generation of soft-tissue fillers for aesthetic facial correction and reconstruction due to its reduced quantity of particles (2.5% of polyacrylamide) and high concentration of water (97.5%). It is a biocompatible, atoxic, homogeneous, and stable product. Additionally, it has good viscosity and elasticity, and it is very simple to use. Although reported in less than 1% of the cases, adverse effects such as pain, swelling, and erythema may occur, which may be the result of inappropriate injection procedure. This article reports the first case of an intraoral foreign body reaction resulting from Aquamid application in the nasolabial fold. Possible causes for this reaction, the chemical composition of the product, and the histopathologic aspects are discussed. PMID:16545711

    A foreign body granuloma is a non-allergic chronic inflammatory reaction that is mainly composed of multinucleated giant cells. Foreign body granulomas may occur after the administration of any dermal filler. Factors such as the volume of the injection, impurities present in the fillers, and the physical properties of fillers affect granuloma formation. The formation of granulomas involves five phases: protein adsorption, macrophage adhesion, macrophage fusion, and crosstalk. The clinical and pathologic features of granulomas vary depending on the type of filler that causes them. Foreign body granulomas can be treated effectively with intralesional corticosteroid injections. Surgical excisions of granulomas tend to be incomplete because granulomas have ill-defined borders and moreover, surgical excisions may leave scars and deformities. PMID:25798398

    To assess the sensitivity of detecting the most commonly encountered foreign bodies in Emergency Radiology using all imaging modalities (conventional radiography, computed tomography, ultrasound, and magnetic resonance imaging). The following materials were inserted into a pig-leg phantom and imaged using conventional radiography, computed tomography, ultrasound, and magnetic resonance imaging: Plastics #1, 2, 3, 5, and compostable plastic; dry and wet wood, aluminum, gravel, glass (tinted and non-tinted), and Salmon and Halibut fish bones. The visibility of plastic is variable on both conventional radiography and computed tomography, depending on composition, but all types of plastic are well visualized on ultrasound. Wood is most easily identified and localized on both computed tomography and ultrasound, is only faintly visible on conventional radiography, and is not well visualized on magnetic resonance imaging. Gravel, glass, and aluminum are well visualized on all modalities, with the exception of magnetic resonance imaging, where there is significant artifact surrounding the foreign body. Fish bones (Halibut and Salmon) are well visualized on conventional radiography, computed tomography, and ultrasound. Conventional radiography and computed tomography are great modalities for detecting foreign bodies of various compositions. Computed tomography is particularly useful at localizing the foreign body and determining its relationship to surrounding structures and its depth of involvement. All foreign bodies are visualized on ultrasound if the location is known and the foreign body is in the plane of the transducer. Magnetic resonance imaging is not helpful in detecting foreign bodies.

    Orbital injuries with a foreign body may result in severe structural and functional damage to the eye or orbital contents. Management and prognosis depend on the composition and location of the foreign body and whether there is secondary infection. Metallic objects and glass are the most frequently encountered and well-tolerated, whereas organic foreign bodies can elicit an inflammatory reaction and lead to serious complications. Despite the modern imaging methods, it is often difficult to identify and locate organic intraorbital foreign bodies. This paper presents a review of nine cases of impacted foreign bodies in the orbital region and discusses the diagnosis and treatment of this kind of injury. The following data were collected: age, gender, etiology of injury, occurrence of fracture, anatomical location of fracture, type of object, signs and symptoms, type of imaging exam used, approach, transoperative complication and occurrence of death. Foreign body injuries in the orbital region can be treated with a combination of clinical suspicion, basic knowledge and diagnostic tests and depend on the skill and experience of the surgeon, thereby decreasing the surgical risk of iatrogenic injury in relation to the inherent risk of retaining an organic intraorbital foreign body.

    Foreign bodies are rare causes of appendicitis and, in most cases, ingested foreign bodies pass through the alimentary tract asymptomatically. However, ingested foreign bodies may sometimes remain silent within the appendix for many years without an inflammatory response. Despite the fact that cases of foreign-body-induced appendicitis have been documented, sharp and pointed objects are more likely to cause perforations and abscesses, and present more rapidly after ingestion. Various materials, such as needles and drill bits, as well as organic matter, such as seeds, have been implicated as causes of acute appendicitis. Clinical presentation can vary from hours to years. Blunt foreign bodies are more likely to remain dormant for longer periods and cause appendicitis through obstruction of the appendiceal lumen. We herein describe a patient presenting with a foreign body in his appendix which had been swallowed 15 years previously. The contrast between the large size of the foreign body, the long clinical history without symptoms and the total absence of any histological inflammation was notable. We suggest that an elective laparoscopic appendectomy should be offered to such patients as a possible management option. PMID:23805364

    Objective: Tracheobronchial foreign body aspirations may cause cardiopulmonary arrest and sudden death. The incidence in children is higher than in adults. Rapid diagnosis and treatment is live saving. In this paper, we aimed to present our experience in tracheal foreign body aspirations and rigid bronchoscopy for 25-years. Materials and Methods: From January 1990 to January 2015, 805 patients with suspected tracheobronchial foreign body aspiration were admitted to our department. Hundred and twelve patients with tracheal foreign body were included in this study. We evaluated patients’ records, retrospectively. Age, gender, clinical symptoms, physical examination findings, radiological evidences, type of foreign body and intervention types were noted. Results: Sixty-five of the patients were female (58%) and 47 patients were male (42%), and mean age was 8.1 years (8 month-58 years). Coughing was the main symptom (n=112, 100%). Other symptoms and findings included dyspnoea and bilateral decreased lung sounds (n=73, 65.1%), bilateral rhonchi (n=68, 60.7%) and cyanosis (n=41, 36.6%). Rigid bronchoscopy was performed in all patients. The most common foreign body was nuts (n=75, 67%). The main radiologic finding was radiopaque image of the related foreign body in 27 patients (n=27, 24.1%). Cardio-pulmonary arrest occurred in 11 patients and two of them died. Conclusion: Tracheobronchial aspirations of foreign bodies are life-threatening events. If not diagnosed and treated rapidly, distressful results can be seen. Warning people by skilled persons on this topic will reduce the incidence of foreign body aspirations. PMID:27551175

In this article, we report a patient with unusual laryngeal foreign body lodgement: a bee which presented with sudden odynophagia and stinging sensation in throat. The bee was detected on the laryngeal mucosa in indirect laryngoscopic examination and removed immediately under general anesthesia in apneic period. In this case report, we describe the importance of detailed anamnesis and laryngeal examination even if the patient has no severe symptoms. PMID:26211866

    Echinoderms have excellent healing and regeneration abilities, but little is known about how they deal with the related challenge of durable foreign bodies that become lodged within their bodies. Here we report a novel mechanism for foreign body elimination in starfish. When injected into the arm of a starfish, passive integrated transponder tags and magnets of similar dimensions are eliminated at a rate approximating 10% per day. These objects are forcefully ejected through the body wall at the distal tip of an arm. Ultrasound images reveal that foreign bodies are moved within the body cavity, and tracking of magnets injected into starfish suggests that the movements are haphazard rather than directed. Constrictions of the body wall near the foreign object are the likely mechanism for this transport process. Open questions include the ecological relevance of this behavior, why clearance occurs through the distal tips of the arms, the neurological and muscular control of this behavior, what other animals use this mechanism, and the range of objects starfish can eliminate in this way.

    Foreign body in the nasal cavity is one of the most common paediatric otolaryngology emergencies and needs to be promptly addressed. The incidence of nasal foreign body getting dislodged secondary to unsuccessful attempts to take it out is quite high and can be potentially dangerous as it might cause fatal airway compromise. The chances of it getting impacted and retained in the nasopharynx are practical, although such cases are seldom encountered for primarily nasal foreign bodies. Nevertheless, the nasopharynx should always be looked for as a site of impaction of hidden foreign objects. Presence of enlarged adenoids could be of help as it may prevent accidental lodgement of displaced foreign body in the airway, but might also result in difficulty in locating and retrieving the foreign body because it acts as an anchor-pad with its grooves and crevasses. This report presents a rare, interesting case of a child with enlarged adenoids anchoring a metallic ring and describes the clinical presentations and relevant management of a nasal foreign body dislodged and lost in the nasopharynx.

    We report the case of a 22-year old man with intracranial metallic foreign bodies who presented complaining of a headache. His history of headaches had begun when he was five years old and continued with increasing severity. Six months before hospital admission, nausea and vomiting began to accompany his headache. Computed tomography scan revealed that 2 metallic foreign bodies were located adjacent to the vertex and another was next to the ambient cistern. The location and position of foreign bodies suggested that they were introduced in infancy through the anterior fontanelle before its closure in an unsuccessful homicide attempt. This case is one of the few reported cases combining headache and intracranial foreign bodies and we discuss the relationship between headache and these metallic materials. PMID:23355931

    Introduction: Foreign body aspiration is a very serious problem and the diversity of clinical protests in each geographic region has its own characteristics and common problems of childhood that is an important cause of mortality and morbidity. No area is separate from this problem and conducting this research is due to achieve basic information regarding foreign body aspiration. Materials and Methods: This was performed as descriptive - cross sectional study on 200 cases that has been hospitalized in Imam Khomeini Hospital, Urmia due to foreign body aspiration problem from 2009 to 2011. And all cases of foreign body aspiration records extracted and analyzed using SPSS 16 software. Results: Foreign body aspiration under 4 years was 57% and was more common in males than females; approximately 74% of patients were hospitalized in the first 10 days and 13% of patients did not remember the initial incident that led to the aspiration. Cough and shortness of breath and reduced lung sounds and wheezing were common symptoms. Chest radiographic findings are not specific and can be normal of a high percentage. The most common aspirated foreign body was food especially sunflower seeds. Right bronchus with 55% of cases was more common than the left bronchus and all patients were treated with rigid bronchoscopy, 24% of patients had complications, 15% had hospitalized with pneumonia. Totally, 75% of patients were urban residents. Discussion: We need to understand all the aspects related to foreign body aspiration and education to the community, to recognize symptoms and type of foreign body in terms of geographical area and to create a strong clinical suspicion in physicians and awareness of its prevalence that by reducing the incidence and early detecting and treatment can reduce the mortality and morbidity and prevent additional expenses.

    Intraorbital foreign bodies usually occur after a high velocity injury such as gunshot or industrial accidents; more rarely they occur following trivial trauma. A retained foreign body can give rise to serious complications, the most devastating of which is loss of the eye. This retrospective, interventional case report reviews the clinical features, radiological appearance and surgical management of two patients who presented at Sultan Qaboos University Hospital, Oman with intraorbital foreign bodies. Details of ocular history, preoperative ocular examination findings including visual acuity, surgical procedure and subsequent management were noted. The two patients, aged 10 years and 9 years old respectively, sustained orbital trauma with sharp objects. Both patients were found to have intraorbital foreign bodies that were documented clearly by computed tomography (CT) scans of the orbit. The first patient presented straight after injury, had no ocular involvement, underwent immediate surgical exploration and ended up with full recovery. The second patient presented to us after a delay of 4 days, and was found to have endophthalmitis. This patient ultimately lost all visual function in the affected eye. A CT scan is the modality of choice for orbital foreign body detection and localization. Early surgical exploration and foreign body extraction greatly influence the visual prognosis and final outcome. PMID:21654960

    The amount of patients presenting at the emergency hospitals with retained rectal foreign bodies appears recently to have increased. Foreign objects retained in the rectum may result from direct introduction through the anus (more common) or from ingestion. Affected individuals often make ineffective attempts to extract the object themselves, resulting in additional delay of medical care and potentially increasing the risk of complications. The goals of radiological patient assessment are to identify the type of object retained, its location, and the presence of associated complications. Plain film radiographs still play an important role in the assessment of retained rectal foreign bodies. PMID:25639182

    Gingival biopsy specimens from eight patients exhibiting a localized, erythematous, or mixed erythematous/leukoplakic gingivitis that was refractory to conventional periodontal therapy were examined histologically and by energy-dispersive X-ray microanalysis. Histologic examination revealed variable numbers of small, usually subtle, sometimes equivocal, and occasionally obvious foci of granulomatous inflammation. Special stains for fungi and acid-fast bacilli were consistently negative. In all cases, the granulomatous foci contained particles of foreign material that were often inconspicuous and easily overlooked during routine histologic examination. Energy-dispersive X-ray microanalysis of these foreign particles disclosed Ca, Al, Si, Ti, and P in most lesions. However, other elements such as Zr, V, Ag, and Ni were found only in specific biopsy specimens. By comparing the elemental analyses, clinical features, and history of the lesions, strong evidence for an iatrogenic source of the foreign material was found in one case, and good evidence in five cases. In the remaining two patients, the source of the foreign particles remains unresolved.

    The paper provides a rationale and indications for diascleral removal of foreign bodies from the anterior chamber of the eyeball, by intraoperatively using ultrasound study. The clinical material presents 148 cases of diascleral removal of foreign (49 magnetic and 49 amagnetic) bodes impacted into the tunics of the anterior eye without evident opacities of optical media and without signs of endophthalmitis. The paper provides a pathogenetic rationale for the method that is lowly traumatic and highly effective (foreign bodies being removed in 99.9% of cases) due to the high precision of location of a scleral cut in the projection of foreign body bedding owing to intraoperative sound usage. A model clinical case of fragment removal is also shown in the paper. The specific features of criteria for using the method are described, by taking into account the anatomic characteristics of orbital eyeball location. PMID:18756799

    Introduction Intracranial needles are rare entities. Intracranial foreign bodies due to non-missile intracranial penetrations are one of the most rarely encountered situations in neurosurgery. Sewing needles are among the more unusual foreign bodies that may be found in the brain. Although uncommon, foreign body cases are important and interesting. Foreign bodies enter the body through trauma or iatrogenic injuries. Needles are mostly inserted through fontanelles, cranial sutures, and more rarely through the orbits in infancy for the purpose of killing unwanted babies. Case Presentation This article presents a case of intracranial foreign body found upon radiography. A 24-year-old female, who two days prior to presentation suffered only once from dizziness, and was otherwise healthy. Conclusions Because this incident may have occurred during the patient’s neonatal period, it may be a case of child abuse. In spite of the very limited number of cases in the literature, having a stepmother, a stepfather, or a babysitter, being the youngest child, or having family members who suffer from psychiatric disorders, (especially if these relatives are responsible for child care), living in a society that allows homicide of children born from extramarital relationships, and being female have been suggested as possible risk factors.

    The analysis of treatment results in 112 patients with foreign bodies in the rectum, aged from 16 to 80 years, was carried out. 99.1% of the patients were men. All the patients were examined and treated in proctology department of the Moscow municipal clinical hospital N 67 from 1969 to 1998. The examination was made by standard scheme, including rectal touch, rectoromanoscopy, X-ray and ultrasonic examinations. In 107 patients the foreign body was removed without surgery, 5 patients required laparotomy. When possible it was removed by fingers and also with use of forceps. When small foreign bodies could not be reached by finger, they were removed through rectoscope. Foreign bodies of big sizes, proximal end of which was in the sigmoid colon, were removed under anasthesia with the help of the assistant who fixed the foreign body through the abdominal wall in the left ileac region. In impossibility of the subject removal by these methods and presence of complications (perforation, peritonitis), laparotomy with subsequent transanal subject removal without colon section was performed, in case of perforation--with wound suturing or colostomy.

    The best modality for foreign body removal has been the subject of much controversy over the years. We have read with great interest the recent article by Souza Aguiar Municipal Hospital, Rio de Janeiro, Brazil, describing their experience with the management of esophageal foreign bodies in children. Non-endoscopic methods of removing foreign bodies (such as a Foley catheter guided or not by fluoroscopy) have been successfully used at this center. These methods could be an attractive option because of the following advantages: Shorter hospitalization time; easy to perform; no need for anesthesia; avoids esophagoscopy; and lower costs. However, the complications of these procedures can be severe and potentially fatal if not performed correctly, such as bronchoaspiration, perforation, and acute airway obstruction. In addition, it has some disadvantages, such as the inability to directly view the esophagus and the inability to always retrieve foreign bodies. Therefore, in Western countries clinical practice usually recommends endoscopic removal of foreign bodies under direct vision and with airway protection whenever possible. PMID:27170838

    Orbital injuries may be associated with the presence of foreign bodies in which long retention leads to damages such as loss of vision or cerebral abscess. We present the case of a 21-year-old male patient that developed ptosis, limitation of movements and an inflammatory reaction in the right eye after being hit by a tree branch. A CT scan of the orbits revealed an increased density in the right orbital cone. After the neurosurgical approach for the removal of the foreign body, a wooden fragment measuring 2.0x0.3 cm, the patient had a good outcome without visual deficits, ptosis regression and resolution of the inflammatory process. The postoperative CT scan didn't identify any remaining foreign body fragment. This case calls attention to the fact that the wooden splinter presented on CT scan with high density (136 HU) two months after the trauma and was removed by a supraorbital craniotomy. PMID:12894292

    An 8 yr old spayed female Italian greyhound was presented with a mass in the cranial abdomen. Preliminary evaluation of the dog revealed a large, cavitary, irregularly shaped mass with no definitive association with any abdominal organs. During an exploratory celiotomy, a 16 cm × 12 cm × 6 cm mass was removed. On subsequent histopathology, extraskeletal osteosarcoma induced by a foreign body granuloma was diagnosed. The foreign body granuloma, based on histopathological findings, was suspected to be secondary to a retained surgical sponge from her routine ovariohysterectomy performed 7 yr prior to presentation. Animals with granulomas induced by foreign bodies can remain asymptomatic for years; however, those granulomas can progress to extraskeletal osteosarcomas, which carry a poor prognosis.

    Foreign body aspiration is a very common problem in children and toddlers and still a serious and sometimes fatal condition. We are reporting on a 2-year-old white asthmatic male who choked on a chick pea and presented with subcutaneous emphysema, and on chest X-ray with an isolated pneumomediastinum but not pneumothorax. On review of the literature an isolated pneumomediastinum without pneumothorax was rarely reported. This presented a challenge in management mainly because of the technique that we had to use in order to undergo bronchoscopy and removal of the foreign body. Apnoeic diffusion oxygenation was used initially while the foreign body was removed piecemeal, and afterwards intermittent positive pressure ventilation was used. The child did very well, and his subcutaneous emphysema and pneumomediastinum remarkably improved immediately post surgery. PMID:1402375

    Purpose Malignant melanoma of the eye is an uncommon condition that is important to recognise. We describe three cases in which ocular foreign bodies have masqueraded as ocular malignant melanoma. Methods Interventional case reports. Results Case 1 describes diathermy-induced carbon particle implantation, during plaque therapy for the treatment of uveal melanoma, mimicking recurrence with extra-scleral invasion. Case 2 shows a foreign body called ‘mullite' mimicking conjunctival melanoma. Case 3 demonstrates a conjunctival foreign body called ‘illite' that mimicked a limbal melanocytic lesion, clinically thought to be either melanocytoma or melanoma. Conclusion This report highlights the importance of careful history taking, examination, and appropriate biopsy in cases of suspected malignant melanoma, to prevent unnecessary and potentially radical treatment.

Paraclinical explorations concluded that trauma to anterior pituitary by a metallic foreign body from the right nostril to the sella, responsible for panhypopituitarism and sinusitis. The headaches are frequent causes of consultation, often treated symptomatically but rarely explored. The direct trauma to the pituitary gland, by a metallic foreign body, is exceptional. We report the case of neglected panhypopituitarism, discovered 31 years after injury with a pair of scissors. PMID:25667695

    The incidents of foreign body ingestion in infants and children are usually viewed as accidents, but these events may be a form of child abuse. We are reporting a case of child abuse who presented with multiple foreign bodies in the gastrointestinal tract. Physicians are required to report abuse when they have reason to believe or to suspect that it occurred. The purpose of reporting is not punishment of the perpetrator - it is the protection of the child. It is certainly in the best interest of the child, because child abuse is a recurrent and usually escalating problem that exposes the child to substantial risk. PMID:23164499

    Foreign body (FB) in the aerodigestive tracts has been commonly reported but findings of impacted foreign bodies in the nasopharynx following inhalation/ingestion are very rare. Most of the FB gets lodged as a result of forceful vomiting, coughing,and digital manoeuvres for removal of FB in the oropharynx. Several objects have been identified lodged in the nasopharynx. No age group is spared although most victims are children under 10 years of age. Foreign bodies in the nasopharynx can be uneventful or potentially dangerous depending on type, size and location as it may cause sudden airway obstruction, or local pressure necrosis of alimentary or respiratory tract or both. Presentation in children is usually with a history of swallowed FB which may not be witnessed in children, choking, cough, bluish discolouration, breathlessness, drooling of saliva, halitosis, rhinorrhoea, snoring, stridor, dysphagia, vomiting and dysphonia. A foreign body in the nasopharynx is a challenge to patient, parents, the physician and the ENT surgeon, as it may be miss-diagnosed, in the index case, as Pharyngotonsilitis. The index patient, a 14 month child,was presented with a two days history of fever, drooling of saliva, mouth breathing, and digital manipulation. Lateral imaging of the post nasal space following initial treatment with antibiotics, aided the diagnosis of a periwinkle shell in the nasopharyngx that was removed during a nasopharyngoscopy under general anaesthesia without complication and subsequently discharged home. This emphasizes a high index of suspicion for FB in the nasopharynx in children with history of missing foreign body, digital manipulation, drooling of saliva and mouth breathing. Lateral X-ray of the postnasal space, neck, chest and abdomen should be the minimum investigation required. PMID:27487618

    A previously healthy 1-year-old boy suddenly began choking and coughing after ingesting a coin. The child's mother attempted to extract the coin by inserting her fingers in his mouth and sweeping the oral cavity. The mother felt the object momentarily with her fingertips but was unable to retrieve it, and brought her son to a local hospital for assistance. The patient was referred to our emergency department (ED) for possible oesophageal obstruction by a foreign body based on the X-ray findings. On arrival at our ED, the child exhibited mild gagging but presented no respiratory symptoms and normal pulmonary examination. The chest X-ray revealed a nasopharyngeal foreign body. The patient was placed under procedural sedation and emergency removal was successfully completed by an otolaryngologist. Subsequently, the patient was discharged without complications.

    Background: Ingestion of foreign bodies may result in the formation of a tracheoesophageal fistula (TEF), which causes severe morbidity in children. We describe four cases of TEF, who underwent emergent surgery for repair. Case presentation: In this report, we present about four patients aged between 9 months to 2.5 years, who referred due to disc battery ingestion. There were two boys and two girls. The common symptoms were cough, cyanosis, and dysphagia, choking and vomiting. The diagnosis was performed through an x-ray, barium swallow and CT Scan. All batteries were impacted in the esophagus, two in upper, one in the middle, and one in lower esophagus position. All disc batteries were removed endoscopically, but had tracheoesophageal fistula (TEF). All the patients underwent TEF repaired surgically. There was no morbidity in four patients, but one patient developed moderate esophageal stenosis, which was repaired by staged dilatation. There was no mortality in our cases. Conclusion: Long-term impaction of foreign bodies may result in tracheoesophageal fistula. This complication may be seen earlier with alkaline disc batteries. Removal of these foreign bodies should be followed carefully for the diagnosis and treatment of these fistulas. PMID:24551442

    The ingestion of a foreign body (FB) is a potentially serious condition. In children, the most common years for FB ingestion are from the age of 6 months to 6 years. FB ingestion also occurs in those with psychiatric disorders or mental retardation and among adult prisoners and alcoholics. Most ingested FBs spontaneously pass out of the body via the gastrointestinal system. An endoscopic or surgical approach is only needed if the object fails to progress through the gastrointestinal tract. All objects impacted in the oesophagus require urgent treatment. This study reports a case of multiple FB ingestion and provides a literature review. PMID:27122280

    Foreign bodies (FBs) retained in the soft tissues are a common reason for medical consultation, and usually consist of wooden or metal splinters or glass shards. Failure to remove foreign bodies is likely to give rise to acute or late complications, such as allergies, inflammation or infection, that may be severe. The surgical removal of an FB is invasive, costly and technically challenging. The procedure may fail in some cases and carries the risk of complications. Our study describes a technique for the ultrasound-guided removal of an FB, devised from our experience, and demonstrates its advantages over the standard surgical procedure. Sixty-two patients (43 males and 19 females aged from 9 to 65 years, median age 31 years) presented at our institution between October 2005 and June 2008 with suspected foreign bodies retained in the soft tissues of various body districts. Radiographic and/or ultrasound diagnosis was established by a radiologist expert in musculoskeletal sonography. The same radiologist helped by a nurse subsequently undertook the ultrasound-guided removal in the outpatient's clinic according to the technique described in the paper. ATL 5000 and PHILIPS iu22 ultrasound systems were used with high-frequency linear-array probes, sterile material, local anaesthetic (lidocaine 2%), scapels and surgical forceps. Antibiotic prophylaxis with amoxicillin and clavulanic acid were prescribed to all patients for 7 days after the procedure. Ninety-five FBs (39 glass, 35 metal, 17 vegetable, 2 plastic, 2 stone) were successfully removed under ultrasound guidance in all patients and the procedure took between 15 and 30 min. No complications arose either during or after the procedure. Seventy-five skin incisions were made and the wounds closed with Steri-Strips in 73/75 cases, whereas skin sutures were used in 2/75 cases. No complications arose either during or after the procedure. Ultrasound-guided removal of an FB retained in the soft tissues is a good

    Foreign body inhalation affects thousands of children every year, and it remains a significant cause of morbidity and mortality in children. Inhaled organic or inorganic foreign bodies can become lodged in the posterior nasopharynx, larynx, trachea, or bronchi. Presentation of foreign body inhalation can range from nonspecific respiratory symptoms to respiratory failure associated with a choking episode. In this issue, an in-depth review of the etiology, pathophysiology, diagnosis, and treatment of inhaled foreign bodies is presented. Risk factors for foreign body inhalation and clinical clues to diagnosis, as well as emergent management of inhaled foreign bodies are reviewed. A systematic approach, as described in this issue, will aid in timely and accurate diagnosis and treatment of inhaled foreign bodies, thereby limiting future complications and morbidity.

    Summary Intraorbital foreign bodies, especially non-metallic ones, remain an important diagnostic and therapeutic problem. Organic foreign bodies contain large quantities of bacterial flora contributing to rapid onset of inflammation which may promptly damage the optic nerve. Further progression of inflammation may involve the structures of central nervous system. US examination is a preliminary, commonly available diagnostic method, although it is not always successful in visualizing foreign bodies. CT scan remains a standard investigation used to visualize intraorbital foreign bodies, although with organic foreign bodies, its results may be inconclusive. MRI allows for visualization and precise identification of foreign bodies, which is vital for surgery. The issue of intraorbital foreign bodies is an interdisciplinary problem requiring the co-operation between ophthalmologists and neurosurgeons. PMID:22802793

    2008-01-01

    The stable hyaline cells (thrombocytoids precursors) are prevailing haemocytes type in young larvae of Calliphora vicina. Their concentration decreased significantly during the crop emptying and became completely absent in wandering larvae. However, the injection of foreign particles into the haemocoel induced evident increase in the number of stable hyaline cells by means of transformation from prohaemocytes within 24 h after the treatment. Maximum of hyaline cells concentration is achieved on the 2-3 day when the part of them starts to transform into prothrombocytoids. Injection of both abiotic (charcoal) and biotic (human erythrocytes) foreign particles exerts an identical effect. Puncture of the body wall, bacterial immunization and injection of saline did not induce hyaline cells appearance. In crop emptying larvae, the stable hyaline cells originate within the clusters of undifferentiated steam cells, i. e. prohaemocytes. After the completion of crop emptying in wandering and diapausing larvae, preliminary dedifferentiation of very young plasmatocytes may be also observed. It is suggested that specification of the stable hyaline cells is induced by thrombocytoids after engulfing of the injected foreign particles and forming of their agglutinates. PMID:18959187

    Foreign body aspiration (FBA) is a dangerous and potentially life-threatening event. We report the case of a 24-month old boy, who was initially presented with an episode of obstructive bronchitis to the family pediatrician. Then, while being treated with empiric antibiotics, he aspirated a peanut. Although resulting in a coughing episode, the mother did initially not ascribe any relevancy to it. Since the diagnosis of obstructive bronchitis had already been established, only an in-depth history taking session with the mother could help figure out, why the boy's symptoms got worse instead of better. This article underlines the importance of accurate history taking and clinical examination. PMID:26236592

    Ingestion of foreign bodies, common in the emergency services, remains a challenge for physicians despite preventive measures and technical progress due to the frequency and possible complications, serious complications that can darken vital prognosis or may be a source of remote morbidity. Clinical experience at "St. Mary" Hospital included, between 2000-2015, 39 patients diagnosed with FB ingestion, of which 26 fixed in the oesophagus, with the remaining 13 having spontaneously progressed along the digestive tract (5 recovered from the stomach, 6 naturally evacuated, and 2 cases with colic perforation). Oesophageal foreign bodies occur consecutively to (in)voluntary ingestion, the vast majority of them passing unnoticed. The most frequently encountered types are coins, batteries, needles, various sharps objects, food, bone fragments, cartilages, pieces of plastic, glass, etc., FB impaction at oesophageal level being usually conditioned by the 3 anatomical narrowings. Typically, FB ingestion occurs at extreme ages, 60% of patients being pre-school children (<6 years), with an even higher percentage--between 70-80% between 6 months and 2 years of age--and only 15% elderly, frequently edentulous. Usual clinical signs, in the absence of complications, are: dysphagia, hypersialorrhoea, low cervical and/or chest strain, sometimes vomiting. Not at all infrequently (30%!), we notice the absence of any sign. Alarming manifestations, which indicate the development of complications, are pyrexia, general physical health deterioration, pain (with vertebral/interscapular projection), pulping, subcutaneous cervical emphysema. Diagnosis via various imaging methods (simple radiography, barium swallow, CT, MRI) remains the essential link in identifying the lesion and establishing a therapeutic approach. Endoscopic evaluation (rigid or flexible) is mandatory, also allowing therapeutic gestures. In terms of progression, 80-90% of FB pass into the stomach, being eliminated naturally

    Injuries to various parts of the digestive tract caused by foreign bodies, frequently deliberately swallowed or inserted using various practics, are less common, however serious injuries. The symptomatology may be vague, credibility is often limited or anamnestic data may be intentionaly missing, which makes the diagnostic process tricky. Undefined, vague signs are related to specificities during the GIT perforation, so called hidden perforation. The recovery is commonly complicated, with a resulting handicap of stool incontinence or of colostomy. This is demonstrated on several subjects, treated in our surgical department. PMID:20052930

    An 18-month-old male patient, classified as American Society of Anesthesiologists I, with bilateral inguinal hernia was scheduled for operation. Preanesthetic evaluation revealed history of completed medical treatment of acute bronchitis 10 days ago, and his respiratory examination was recorded as normal. He was successfully operated under general anesthesia with a laryngeal mask. After removal of the laryngeal mask, he displayed signs of hypoxia. Respiratory sounds were undetectable in the left thorax. He was intubated due to failure of adequate ventilation. Positive pressure ventilation and bronchodilators were administered to provide sufficient ventilation. In his chest X-ray, total atelectasis was determined in the left lung. Pleural effusion was ruled out with thoracic ultrasonography. Diagnostic rigid bronchoscopy was performed, and in left bronchial tree, hazelnut fragments were removed. The patient's hemodynamic and respiratory parameters recovered quickly after foreign body removal, and the patient was transferred to intensive care unit. His parents were questioned for persistent respiratory symptoms and they gave information about repeating respiratory tract infections in the last 3 months. We predict that displaced foreign body in lobar bronchus due to mechanical ventilation can cause this condition. PMID:27555159

    Objective. The demand and usage of button batteries have risen. They are frequently inadvertently placed by children in their ears or noses and occasionally are swallowed and lodged along the upper aerodigestive tract. The purpose of this work is to study the different presentations of button battery foreign bodies and present our experience in the diagnosis and management of this hazardous problem in children. Patients and Methods. This study included 13 patients. The diagnostic protocol was comprised of a thorough history, head and neck physical examination, and appropriate radiographic evaluation. The button batteries were emergently extracted under general anesthesia. Results. The average follow-up period was 4.3 months. Five patients had a nasal button battery. Four patients had an esophageal button battery. Three patients had a button battery in the stomach. One patient had a button battery impacted in the left external ear canal. Apart from a nasal septal perforation and a tympanic membrane perforation, no major complications were detected. Conclusion. Early detection is the key in the management of button battery foreign bodies. They have a distinctive appearance on radiography, and its prompt removal is mandatory, especially for batteries lodged in the esophagus. Physicians must recognize the hazardous potential and serious implications of such an accident. There is a need for more public education about this serious problem. PMID:23936851

    Background The aim of this study was to investigate the antiscarring effects of pirfenidone on foreign body reaction in a rabbit model of glaucoma drainage implant surgery. Methods Adult New Zealand White rabbits had glaucoma drainage device implantation using Model FP8 Ahmed glaucoma valves. One eye was randomly assigned to receive postoperative intrableb injection of pirfenidone followed by topical treatment. The other eye underwent the same procedure but without the addition of pirfenidone. Histochemical staining and immunohistochemistry for blebs were performed. Results The degree of cellularity was smaller in the pirfenidone group than in the control group at 2 weeks post operation (P=0.005). A few foreign body giant cells were detected in the inner border of the capsule, and their numbers were similar in the control and pirfenidone groups (P>0.05). Using Masson’s trichrome stain, the inner collagen-rich layer was found to be thinner in the pirfenidone group than the control group at 4 weeks (P=0.031) and 8 weeks (P=0.022) post operation. The percentage of proliferating cell nuclear antigen-positive cells was lower in the pirfenidone group than in the control group at 2 weeks post operation (total bleb, P=0.022; inner bleb, P=0.036). Pirfenidone treatment decreased the immunoreactivity of connective tissue growth factor at 2 weeks post operation (total bleb, P=0.029; inner bleb, P=0.018). The height and area of α-smooth muscle actin expression were lower in the pirfenidone group than the control group at 2 weeks, 4 weeks, and 8 weeks post operation (all P<0.05). Conclusion Postoperative intrableb injection of pirfenidone followed by topical administration reduced fibrosis following glaucoma drainage device implantation. These findings suggest that pirfenidone may function as an antiscarring treatment in foreign body reaction after tube-shunt surgery. PMID:27143855

    Ocular injury secondary to foreign body remains an important cause of ocular morbidity with or without blindness in working population. Intraocular foreign body may have varied clinical presentation. Initially it may look an apparently normal eye followed by obvious ocular symptoms depending upon its location and degree of inflammation. It can result in partial or full thickness penetration of sclera with or without involvement of posterior segment. We hereby present two cases of metallic intrascleral foreign body entry through upper lid in young carpenters following hammer and chisel injury. In case 1, Intrascleral location of foreign body was confirmed with X ray orbit and B scan ultrasonography while in case 2 the diagnosis of intrascleral foreign body was missed at the first visit to ophthalmology clinic Both the patients underwent exploratory surgeries where intrascleral metallic foreign bodies were found without ocular penetration. An intrascleral foreign body may be missed due to small penetrating scleral wound covered by a large subconjunctival haemorrhage accompanied by minimal or no signs of inflammation and failure on part of treating ophthalmologist to suspect an intrascleral foreign body. To establish a diagnosis of intraocular particularly intrascleral foreign body, careful history taking and clinical examination along with use of imaging studies are mandatory steps which help in successful management and good visual outcome. These cases highlight the importance of considering a presumptive diagnosis of retained intrascleral foreign body in every patient with a history of penetrating ocular trauma through lid or a visible wound/scar on the lid.

    Objective: Foreign bodies can be deposited in the oral cavity either by traumatic or iatrogenic injury. The most common foreign bodies of iatrogenic origin encountered are restorative materials, like amalgam, and root canal fillings. The aim of this study was to determine the prevalence of foreign bodies detected with panoramic radiography in the jawbones, as well as to evaluate the etiology and characteristics of these pathologies. Materials and Methods: From March 2012 to January 2014, 11,144 panoramic radiographs were taken and retrospectively reviewed. The number, characteristics, location of the foreign bodies, age, and gender of the patients were recorded. Results: Of the 11,144 patients reviewed, 62 of them have a foreign body with a frequency of 0.6%. The patients who had a foreign body were between 14 and 81 years old. Female patients showed more foreign bodies than male patients. Among the 62 patients, 63 filling materials, one stapler, and five shrapnel were detected. Only 8 patients had symptoms associated with foreign bodies and these foreign bodies excised surgically. Conclusion: If possible, these pathologies must be removed at the time of detection to prevent further complications; however, in asymptomatic cases, according to location and the characteristic of the foreign body, they can be kept under observation without performing any operations.

Among 37,466 bronchoscopies performed between 1974-1998, 62 (0.2%) were performed for the removal of tracheobronchial foreign bodies. Medical history was suggestive of foreign body aspiration in 33 patients and the chest radiograph was suggestive in 10 patients. The procedure was performed with the flexible bronchoscope in 42 patients (68%), rigid bronchoscope in 4 (6%), and with both in 16 (26%) patients. Foreign bodies were found in the right bronchial tree on 42 occasions, in the left on 20 and in the trachea once. In 39 patients, inflammatory granulations were found around the foreign body. The origins of the foreign bodies included: bone fragments (n=31), vegetable (n=10), broncholith (n=8), a part of dental prosthesis (n=7), endodontic needle (n=2), a metallic (n=2), or plastic (n=1) particle, a tracheostomy tube (n=1) and a match (n=1). In one patient, 2 foreign bodies were found. The foreign bodies were successfully removed in all but 2 patients (3%). The most useful instruments for removal were alligator forceps and the wire basket. Foreign bodies in the tracheobronchial system are rare in adults. They can be successfully removed in the majority of patients under either flexible or rigid bronchoscopy. PMID:10573222

    Ocular injury secondary to foreign body remains an important cause of ocular morbidity with or without blindness in working population. Intraocular foreign body may have varied clinical presentation. Initially it may look an apparently normal eye followed by obvious ocular symptoms depending upon its location and degree of inflammation. It can result in partial or full thickness penetration of sclera with or without involvement of posterior segment. We hereby present two cases of metallic intrascleral foreign body entry through upper lid in young carpenters following hammer and chisel injury. In case 1, Intrascleral location of foreign body was confirmed with X ray orbit and B scan ultrasonography while in case 2 the diagnosis of intrascleral foreign body was missed at the first visit to ophthalmology clinic Both the patients underwent exploratory surgeries where intrascleral metallic foreign bodies were found without ocular penetration. An intrascleral foreign body may be missed due to small penetrating scleral wound covered by a large subconjunctival haemorrhage accompanied by minimal or no signs of inflammation and failure on part of treating ophthalmologist to suspect an intrascleral foreign body. To establish a diagnosis of intraocular particularly intrascleral foreign body, careful history taking and clinical examination along with use of imaging studies are mandatory steps which help in successful management and good visual outcome. These cases highlight the importance of considering a presumptive diagnosis of retained intrascleral foreign body in every patient with a history of penetrating ocular trauma through lid or a visible wound/scar on the lid.

    Ingestion of foreign bodies is a common pediatric problem. The majority of ingested foreign bodies pass spontaneously. Oesophageal foreign bodies should be urgently removed because of their potential to cause complications. Ingested batteries that lodge in the oesophagus, sharp or pointed foreign bodies in the oesophageal or gastric tract, and ingestion of multiple magnets all require urgent endoscopic removal. A 4-year-old boy ingested a sharp magnetic foreign body, which was removed via rigid oesophagoscopy without complication. To the best of our knowledge, this is the only sharp magnetic foreign body ingested by a young child ever reported in the English-language literature. We describe the presentation and therapeutic procedure adopted in this case. PMID:27368455

    Inhalation of foreign bodies is relatively frequent in children, but exceptional in adults. Various kinds of foreign bodies can be inhaled, the type generally depends on eating habits in adults. We reviewed a series of 50 consecutive cases of inhaled foreign bodies and found that naseberry fruits (Sapodilla plum) was the primary cause, followed by bone debris. This series is typical of Eastern Asia, particularly South Vietnam. Most of the foreign bodies were extracted under local anesthesia using fibroscopy with a foreign body forceps. Most of the foreign bodies were on the right side. The naseberry nut is not radio-opaque, so diagnosis was generally established late after infectious complications. The endoscopic aspect was typical and should be recognized by endoscopists working in Vietnam. PMID:15699907

    Percutaneous extraction techniques are an established method for removing endovascular foreign bodies. Generally, the foreign body to be removed is radiopaque (i.e., catheter and guidewire fragments, vena cava filters, embolization coils, endovascular stents). We propose an application of these techniques to remove a radiolucent foreign body (i.e., pigtail cover) by means of a combination of different imaging techniques (fluoroscopy, digital subtraction angiography, ultrasound, and computed axial tomography).

    A 2-year-old child presented to the emergency department with an acute onset of dysphagia and stertor. A plain anteroposterior chest X-ray revealed a single circular opacity in the middle third of the oesophagus consistent with an ingested coin. The child was taken to the theatre for rigid pharyngo-oesophagoscopy and removal of the coin. After the first coin was removed subsequent endoscopic examination revealed a second coin at the same location. This extremely rare case of two ingested coins becoming impacted with perfect radiological alignment emphasises the importance of thorough examination on endoscopy and the potential limitations of an X-ray in initial assessment of an ingested foreign body.

    Flow diverter stents are new important tools in the treatment of large, giant, or wide-necked aneurysms. Their delivery and positioning may be difficult due to vessel tortuosity. Common adverse events include intracranial hemorrhage and ischemic stroke, which usually occurs within the same day, or the next few days after the procedure. We present a case where we encountered an unusual intracerebral complication several months after endovascular treatment of a large left internal carotid artery aneurysm, and where brain biopsy revealed foreign body reaction to hydrophilic polymer fragments distally to the stent site. Although previously described, embolization of polymer material from intravascular equipment is rare. We could not identify any other biopsy verified case in the literature, with this particular presentation of intracerebral polymer embolization--a multifocal inflammation spread out through the white matter of one hemisphere without hemorrhage or ischemic changes.

    Optimal treatment of intralenticular metallic foreign-body injuries remains controversial, especially in patients with clear lenses and good vision. Using 20 rabbit eyes, we examined the cataractogenic potential of intralenticular iron and its effects on the retina. Iron wire implanted into the lenses of 12 rabbit eyes caused cataracts in every eye within 4 weeks. However, after 4 1/2 weeks, none of these eyes showed evidence of retinal siderosis. No cataracts developed in five eyes with intralenticular glass, while three with intravitreal iron showed marked retinal toxicity. These results suggest that as long as the lenses remain clear, conservative management of these injuries carries minimal risk of permanent retinal damage. PMID:7596542

    We report a case of an intravesical foreign body that was incompletely removed endoscopically and that defied diagnosis with current diagnostic tools. A 65-year-old man visited Korea University Anam Hospital complaining of dysuria and a sensation of residual urine. His medical history included an intravesical foreign body caused by penetrating trauma, and he had undergone endoscopic removal of foreign bodies 1 year previously. After additional remnant intravesical foreign bodies were found, he had undergone additional endoscopic removal and his urinary symptoms subsided. After 2 years, however, he again presented to the clinic complaining of dysuria and gross hematuria. Cystoscopy and computed tomography for intravesical foreign bodies were performed, but no evidence of a remnant foreign body was found. Open exploration revealed a remnant foreign body penetrating the bladder. A partial cystectomy including the foreign body was performed. We suggest that cases of penetrating injury with a radiolucent object may warrant primary open exploration and foreign body removal owing to the inherent difficulties in diagnosis and endoscopic treatment of such objects.

    Ingested and aspirated foreign bodies are a common occurrence in children and are important causes of morbidity and mortality in the pediatric population. Imaging plays an important role in the diagnosis of ingested and aspirated foreign bodies in children and can be crucial to guiding the clinical management of these patients. Prompt identification and localization of ingested foreign bodies is essential to determining the appropriate treatment, as several types of commonly ingested foreign bodies require urgent removal and others can be managed conservatively. In particular, disk batteries impacted in the esophagus carry a high risk of esophageal injury or perforation; multiple ingested magnets can become attracted to each other across bowel walls and cause bowel perforation and fistula formation; and sharp objects commonly cause complications as they pass through the gastrointestinal tract. Accordingly, these ingested foreign bodies warrant aggressive clinical management and therefore radiologists must be familiar with their imaging appearances and clinical implications. Prompt recognition of secondary radiographic signs of foreign-body aspiration is also crucial, as clinical symptoms can sometimes be nonspecific and most aspirated foreign bodies are radiolucent. Overall, radiography is the most important modality in the evaluation of ingested or aspirated foreign bodies; however, fluoroscopy and computed tomography play an ancillary role in complicated cases. It is essential that every radiologist who interprets imaging examinations of children be aware of the imaging appearances of commonly ingested and aspirated foreign bodies and their clinical significance.

  17. Identification of radiolucent foreign bodies in tissue using optoacoustic spectroscopic imaging

    2011-03-01

    One of the leading causes of medical malpractice claims in emergency medicine is the misdiagnosis of the presence of foreign bodies. Radiolucent foreign bodies are especially difficult to differentiate from surrounding soft tissue, gas, and bone using existing clinical imaging modalities. Because many radiolucent foreign bodies have sufficient contrast for imaging in the optical domain, we are exploring the use of laser-induced optoacoustic imaging for the detection of foreign bodies, especially in orbital and craniofacial injuries, in which the foreign bodies are likely to lie within the penetration depth of visible and near infrared wavelengths. In order to evaluate the performance of optoacoustic imaging for clinical detection and characterization, common foreign bodies have been scanned over a range of visible and near infrared wavelengths to obtain the spectroscopic properties of the materials commonly associated with these foreign bodies. The foreign bodies are also being embedded in realistic ex vivo tissue phantoms to evaluate the changes that may occur in the spectroscopic absorption of the materials due to the interaction with tissue absorbers. Ultimately, we anticipate that spectroscopic characterization will help identify specific wavelengths to be used for imaging foreign bodies that will provide useful diagnostic data about the material properties of the object, thereby enabling the characterization, as well as the location, of the objects. This information will aid the clinician in choosing the optimal treatment course for the patient.

    INTRODUCTION Rectal foreign bodies are rare colorectal emergencies. They are important for the complications that may occur. Delayed response causes a wide range of complications or may even result in death. PRESENTATION OF CASE A 22 years old male patient was seen at our hospital with anal pain, discharge, and complaining of incontinence. The patient stated that a bottle of beverage was placed into his anal canal in an inverted manner for sexual satisfaction 5 years previously. DISCUSSION After clinical and radiological assessment under general anaesthesia in the lithotomy position the object was removed by a laparotomy. He was advised to seek legal help and he received psychiatric treatment in the postoperative period prior to his discharge. CONCLUSION Complications such as abscess, perianal fistula complicated by severe pelvic sepsis and osteomyelitis were expected complications in this case. As in this case, a surgical approach may eliminate dissection planes, increasing morbidity and mortality related to the injuring of surrounding bodies during object extraction. PMID:25553525

    A new contraceptive option, medroxyprogesterone acetate (MPA) and estradiol cypionate (E2C) (MPA/E2C, Lunelle Monthly Contraceptive Injection), will soon be available for women in the US. This article reports the results of a US trial that assessed the effects of body weight and injection site on the pharmacokinetics of MPA, the progestin mediating contraceptive efficacy. This assessment was part of a nonrandomized, open-label, multicenter US study in healthy women receiving a monthly injection of MPA/E2C for 60 weeks. A total of 77 women (aged 18-47 years) at four centers participated in the pharmacokinetics assessment during the sixth or the seventh injection. For determination of serum MPA concentration-time profiles, blood samples were collected before the sixth and seventh injections (day 0) and on days 3, 7, 14, 21, and 28 after the sixth and seventh monthly administrations. For effects of injection site, MPA pharmacokinetics were compared at injection sites of the arm, hip, and leg. The pharmacokinetics of MPA, determined at the sixth and seventh injection, were not significantly affected by injection sites. The mean area under the curve (AUC0-28), however, was different between the arm and the leg injection sites; the difference was < 20%. More important, the average MPA trough concentrations (Cmin) at the fifth and sixth monthly injections were similar (range 0.42-0.51 ng/mL) for the three injection sites and well above the threshold levels of 0.10-0.20 ng/mL required to suppress ovulation. For effects of body mass index (BMI) on pharmacokinetics, women were stratified into three groups: thin/normal (BMI 18-28, n = 48), obese (BMI 29-38, n = 23), and highly obese (BMI > 38, n = 6). There were no significant differences in the pharmacokinetics of MPA among the three BMI categories. The only significant difference (p = 0.0387) was the AUC0-28 between BMI 18-28 and BMI 29-38. Because of the small sample size in the highly obese group, a reanalysis was

    Intrapleural foreign bodies are rare and there are few reports on the occurrence and management of this uncommon clinical presentation. We report a case of a patient with a history of ingesting multiple foreign bodies, which resulted in multiple laparotomy procedures for extraction. The patient recently required surgical removal of innumerable ingested foreign bodies from the stomach and developed a left empyema post-operatively. Subsequent imaging studies revealed evidence of a foreign object in the left pleural space without evidence of an esophageal perforation or diaphragm injury.

    Foreign objects are occasionally seen on computed tomography and could pose a diagnostic challenge to the radiologist and clinicians. It is important to recognize, characterize and localize these objects and determine their clinical significance. Most foreign objects in and around the heart are the result of direct penetrating injury or represent venous embolization to the heart. Foreign objects may cause symptoms and require prompt medical attention or maybe asymptomatic. Clinicians should be familiar with foreign objects that are encountered and understand treatment options. This paper looks at some of foreign objects that can be found and correlates with pathology where possible. PMID:27139781

    A new mouse model of foreign body infection has been developed. Intraperitoneal placement of a silicone catheter followed by injection of 10(8) Staphylococcus aureus organisms resulted in a reproducible, localized foreign body infection. The infection persisted as an intra-abdominal abscess surrounding the catheter for at least 30 days. Treatment with up to nine doses of methicillin or gentamicin or both was started 3 days after infection. The treatment showed a significant effect (P < 0.05), measured as reduction of bacteria on the foreign body, for all three regimens with a reduction of up to 2 log units, but no synergism was observed. The result of the treatment was poor, despite the facts that the local concentrations of methicillin were greater than the MIC for at least 72 h and that nine peak concentrations of gentamicin of > 13 micrograms/ml were obtained. The poor result of the treatment was not caused by development of antibiotic resistance or influenced by protein concentration, pH, or local presence in the pus of inhibitors of antibiotics. Both antibiotics showed good effects in time-kill studies in vitro on bacteria on catheters taken out of infected mice and catheters infected in vitro. During treatment, the proportion of intracellular bacteria increased in all treated mice to 60 to 75% compared with 20 to 30% in nontreated mice (P < 0.05). This indicates that intracellular survival of staphylococci may influence the outcome of the treatment in foreign body infections. PMID:7811017

    Unintentional foreign bodies' swallowing is a fairly common occurrence in ENT consultation especially among children. They usually pass through the gastrointestinal tract without complications. Migration of a foreign body through the esophageal wall is rare. It represents about 1% to 4% of all cases of foreign bodies' ingestion. A 16 year's old female patient has presented to ENT emergency with a painful dysphagia following an accidental ingestion of a metallic pin. Cervical X ray confirmed the presence of the pin while endoscopic investigations have shown no foreign body. Cervical CT scan revealed the migration of the foreign body through the esophageal wall with left vertebral artery dissection. Endoscopic management has been sufficient with an uneventful post operative follow up. Esophageal foreign bodies are very diverse mainly dominated by fish bones (60%) and chicken bones (16%). Metallic pins are rare. The major risks of migration of those foreign bodies are cervical abscess, mediastinitis and oeso-vascular fistulae. Cases of self extrusion through the skin have been reported. Migration of a foreign body through the esophageal wall is rare. Endoscopic management has been sufficient. PMID:25018833

    Introduction. Foreign body aspiration is an emergency condition and may be fatal. Delayed diagnosis and treatment may be associated with complications. This study evaluated the association between time until treatment and complications due to foreign body aspiration. Methods. This study was a retrospective study conducted at Khon Kaen University Hospital, Thailand. We enrolled patients diagnosed with foreign body aspiration with evidence of foreign body detected using direct laryngobronchoscopy at any area from the larynx to the bronchus. Descriptive statistics were used to analyze the association of times of treatment with complications of foreign body aspiration. Results. During the study period, there were 43 patients that met the study criteria. The most common age group was 0–2 years. Plant seeds were the most common foreign bodies (41.9%), and the right main bronchus was the most common site (16 patients, 37.2%). There were 30 patients (69.8%) that experienced complications from foreign body aspiration. Pneumonia was the most common complication (14 patients, 32.6%). The retention time was not significantly associated with the presence of complications (p value: 0.366). Two patients (4.7%) died due to complete airway obstruction and prolonged hypoxia. Conclusion. Times until treatment were not significantly associated with complications from foreign body aspiration.

    Clinical picture of extraocular foreign bodies in the orbit is analyzed in 49 patients, specific features of the diagnosis and treatment of this condition are discussed. Study of the topography of foreign bodies in the orbit has helped distinguish the clinically significant area of fragment localization, areas at a high risk of developing complications, and 'quite' areas. A localizing probe on a space molding was found an effective diagnostic tool. Using this probe, stereotopic localization of a foreign body may be associated with roentgen-negative intraorbital structures, i.e. vessels, nerves, muscles. Topographic location of a foreign body helped explain a considerable vision acuity reduction in relatively transparent media, recurrences of hemorrhages to the fundus oculi, and the type of the pain syndrome. Foreign body removal is indicated in stubborn persistent pain and regressive time course of changes. PMID:2264220

    Reported herein is a 41-year-old male who presented for ultrasound due to two episodes of lower urinary tract infections within a period of 5 months. The sonographic examination revealed an elongated foreign body in the urethra extending into the urinary bladder. Self-insertion of foreign bodies into the urethra is usually done for erotic stimulation. However, foreign bodies can be inserted by children due to curiosity and by mentally retarded people, patients with psychiatric disorders as well as by intoxicated patients and in confusional states. Due to embarrassment, the patients seek medical help only when they are symptomatic and hence some of the foreign bodies are removed only several months after insertion. Detection might be either by plain abdominal films when the foreign bodies are radiopaque or by the use of contrast media. In the case presented by us, this was done by sonography. Endoscopic removal of these foreign bodies is considered the treatment of choice. Recurrent or chronic unexplained urinary tract infections should raise a high index of suspicion to the possible existence of a foreign body in the urethra and/or urinary bladder. PMID:10859554

    Introduction: Foreign body injuries with date thorns, metal and wooden splinters are common in Middle East region, as most of it is desert. Some of the injuries lead to cellulitis or abscess formation, if neglected or improperly managed results in osteomyelitis or septic arthritis of foot structures. This is the first report of isolated navicular osteomyelitis following neglected foreign body in a paediatric foot. Case Report: A 10 year old male patient presented with discharging sinus in left mid-foot 3 years after penetrating injury with wooden splinter. The diagnosis of navicular osteomelitis is confirmed with plain radio-graphs. The ultrasound of foot was done to localize the foreign bodies. Patient was treated with complete removal of foreign body (wooden splinters), surgical debridement and combination of IV and oral cloxacillin for period of 6 weeks. At 18 months follow up, patient had painless foot with no recurrence or collapse of navicular bone. Conclusion: The neglected foreign body can result in osteomyelitis of small bones of foot in pediatric patient. The ultrasound is more useful tool in localizing foreign bodies; those are not radio-opaque. Early and prompt diagnosis with adequate treatment of established osteomyelitis by complete removal of foreign body, curettage and antibiotics can give good results. PMID:27298914

    Results of treatment of 40 patients (43 eyes) with foreign bodies in the posterior segment of the eye are discussed. Special attention is paid to correct assessment of the risk and efficacy of removal of a fragment in each case. Only 67.5% of patients presented with obvious indications for removal of a foreign body through the vitreous. Fragments were removed in 83.3% of these patients. Complications occurred in 6.6%. The main causes of failure of sparing removal of a foreign body from the posterior segment of the eye were detachment of the retina and hemophthalmia. PMID:10377863

    Radiologic diagnosis of colorectal foreign bodies is usually not very difficult, because inserted materials are often clearly visible on plain abdominal radiographs. However, when they are radiolucent, a plain abdominal radiograph has been reported to be useless. As radiolucent colorectal foreign bodies appear as radiolucent artificial contours or air-trapped materials in the pelvis, almost always the diagnosis itself can be made by careful evaluation of plain abdominal radiographs. We encountered a case of casting type of radiolucent colorectal foreign body formed from polyurethane foam. It presented us with unexpected radiologic findings and led to diagnostic difficulties.

    Anorectal injuries due to autoerotic activity with rectal foreign bodies were identified in four male patients. The objects were bottle in one patient, glasses in two patients, and showerhead in one patient. Foreign bodies were extracted within lithotomy position after anal dilatation, under general anesthesia in 3 patients. One patient presented with peritoneal irritation and had a diagnosis of rectal perforation. He underwent transanal rectal repair with proximal fecal diversion. In this paper we described 4 patients who had anorectal injuries due to autoerotic activity with foreign bodies and reviewed the management options in literature. PMID:23533918

    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. PMID:3580073

    A 15-month-old girl developed persistent cough with no associated history of foreign body aspiration. Chest X-ray showed a U-shaped radiopaque foreign body, which was initially thought to be a hairpin, in the right main bronchus. Rigid bronchoscopy was performed and the foreign body turned out to be a light-emitting diode (LED) bulb. In this article, we report our experience of LED bulb aspiration in children, with the view to raise the awareness of clinicians about this potentially life-threatening emergency. PMID:26311014

    Hepatic abscess due to perforation of the gastrointestinal tract caused by ingested foreign bodies is uncommon. Pre-operative diagnosis is difficult as patients are often unaware of the foreign body ingestion and symptoms and imagiology are usually non-specific. The authors report a case of 62-year-old woman who was admitted with fever and abdominal pain. Further investigation revealed hepatic abscess, without resolution despite antibiotic therapy. A liver abscess resulting from perforation and intra-hepatic migration of a bone coming from the pilorum was diagnosed by surgery. The literature concerning foreign body-induced perforation of the gastrointestinal tract complicated by liver abscess is reviewed. PMID:17457985

    Subcutaneous penile insertion of foreign bodies is a practice performed globally but has mostly been reported outside of the United States. An incarcerated 29-year-old Caucasian male in a midwestern prison whittled a domino into a dog bone shape and placed it into his ventral penile subcutaneous tissue. He presented to our facility with erosion of the corners of the foreign body through his skin without evidence of infection. Self-insertion of foreign bodies into penile subcutaneous tissue by incarcerated American men for sexual enhancement is more widespread than previously reported. Erosion is a novel presentation.

    At the moment foreign substances in food are detected mainly by using mechanical and optical methods as well as ultrasonic technique and than they are removed from the further process. These techniques detect a large portion of the foreign substances due to their different mass (mechanical sieving), their different colour (optical method) and their different surface density (ultrasonic detection). Despite the numerous different methods a considerable portion of the foreign substances remain undetected. In order to recognise materials still undetected, a complementary detection method would be desirable removing the foreign substances not registered by the a.m. methods from the production process. In a project with 13 partner from the food industry, the Fraunhofer - Institut für Holzforschung (WKI) and the Technische Unsiversität are trying to adapt thermography for the detection of foreign bodies in the food industry. After the initial tests turned out to be very promising for the differentiation of food stuffs and foreign substances, more and detailed investigation were carried out to develop suitable algorithms for automatic detection of foreign bodies. In order to achieve -besides the mere visual detection of foreign substances- also an automatic detection under production conditions, numerous experiences in image processing and pattern recognition are exploited. Results for the detection of foreign bodies will be presented at the conference showing the different advantages and disadvantages of using grey - level, statistical and morphological image processing techniques.

    Materials used in neurosurgery to achieve hemostasis may be of resorbable or nonresorbable substance and may cause foreign body granuloma if left at the operative site. Foreign body granuloma depending on clinical history may be indistinguishable from an abscess, resolving infarction, and hematoma. Here we present two cases, who had decompressive craniectomy following road traffic accident. Follow-up computerized tomography (CT) scan revealed hyperdense lobulated lesion with peripheral rim enhancement. On magnetic resonance imaging (MRI), lesions were predominantly hypointense on T1-weighted images, and hyperintense on T2-weighted images and showed a lack of restricted diffusion. In view of recent craniectomy and imaging findings diagnosis of foreign body granuloma was made. Both patients underwent surgery, intraoperatively gauze pieces were retrieved from lesions which confirmed preoperative diagnosis. The combination of CT and MRI can diagnose foreign body granuloma, especially in trauma settings. Thus, we can help the surgeon by providing the probable diagnosis for proper management.

    Background: Seasonality is noted in various aspects of human behavior and functioning which have led to an increasing interest in their seasonality in the recent years. Aims: We aimed to examine the seasonal variation in the incidence of rectal foreign bodies in the US using a large inpatient database. Methods: We used the Nationwide Inpatient Sample database to identify patients aged ≥18 years admitted with a primary diagnosis of the rectal foreign body from 2009 to 2011. We used the Edward's recognition and estimation of cyclic trend method to study the seasonal variation of the incidence of rectal foreign body and Z-test to compare the seasonal incidences. Results: A total of 3359 hospitalizations with primary diagnosis of the rectal foreign body were reported from 2009 to 2011. The peak incidence of rectal foreign bodies was seen in October (peak/low ratio 1.20, 95% confidence interval [CI]: 1.10–1.32). Conclusion: Data on seasonal variation of rectal foreign bodies are extremely limited. Further studies would be required to verify whether our findings of a higher incidence in the fall season are reflective of acute changes in the length of the days, climate, sleep-wake cycle, or decreased sexual intercourse at this time of the year. High suspicion at this time of the year may help promptly diagnose and avoid unnecessary investigations. PMID:27213144

    The incidence of rectal foreign bodies is increasing by the day, though not as common as that of upper gastrointestinal foreign bodies. Various methods for removal of foreign bodies have been reported. Removal during endoscopy using endoscopic devices is simple and safe, but if the foreign body is too large to be removed by this method, other methods are required. We report two cases of rectal foreign body removal by a relatively simple and inexpensive technique. A 42-year-old man with a vibrator in the rectum was admitted due to inability to remove it by himself and various endoscopic methods failed. Finally, the vibrator was removed successfully by using tenaculum forceps under endoscopic assistance. Similarly, a 59-year-old man with a carrot in the rectum was admitted. The carrot was removed easily by using the same method as that in the previous case. The use of tenaculum forceps under endoscopic guidance may be a useful method for removal of rectal foreign bodies. PMID:26576143

    In order to extract foreign body from the complex channel background and cotton layers, a detection method which combined improved Otsu threshold with background estimation threshold is presented. Firstly, the original image which containing multiple foreign fibers is divided into two new images which containing only two substances by Otsu threshold. And then using the estimated value of the means and the standard deviations of the two new images a background estimation threshold was determined. The foreign fibers are extracted by the estimation threshold. Simulation results show that this method can overcome the effect which caused by the channel background interference and diversity of the foreign fibers in the actual working environment and can extract foreign bodies quickly and effectively.

    Two unusual events concerning intraocular foreign bodies are presented. The first patient had an occult or unsuspected intraocular foreign body. He showed iridoplegia with mydriasis, siderosis iridis, and an intraocular piece of iron lying posteriorly near the retina. The foreign body was removed and the patient regained normal iris color and pupillary activity. His vision remains 20/15 six years postoperatively dispite ensuing retinal detachment one year after removal of the foreign body. The second patient was a young boy injured by a blasting cap explosion. He lost one eye from the injury and had a piece of intraocular brass in his left eye. In spite of the development of chalcosis and a mature cataract the lens gradually shrank in the pupillary space permitting a clear aphakic area and 20/25 vision. The brass fragment migrated forward and inferiorly and was finally extruded under the conjunctiva five years later, where it was removed and chemically analyzed by x-ray diffraction.

    Statement of the Problem Impaction of foreign bodies in the soft tissues is a sequela of traumatic and penetrating injuries. Such foreign bodies should be removed due to the complications they cause. Patient’s history, clinical evaluation and imaging examinations aid in the proper detection and localization of the foreign bodies.   Purpose The aim of the present study was to compare the sensitivity of computed tomography (CT) and ultrasonography for detecting foreign bodies in in-vitro models simulating facial soft tissues. Materials and Method Fifty foreign particles with five different compositions including wood, glass, metal, plastic, and stone were embedded in five calf tongues at 1, 2, 3, 4 and 5 cm depths. CT and ultrasonography were compared regarding their capability of detecting and localizing the foreign bodies. Results Wood and plastic foreign bodies were demonstrated more clearly on ultrasonography images. High density materials such as metal, stone, and glass were detected with almost the same accuracy on CT and ultrasonography examinations. Visibility of the foreign bodies deteriorated on ultrasonography images as their depth increased; however, CT appearances of the foreign particles were not influenced by their depths. Conclusion Ultrasonography is an appropriate technique for detection of foreign bodies especially the ones with low density. Therefore, it seems logical to perform ultrasonography in combination with CT in cases with the suspicion of foreign body impaction. PMID:27602392

    1997-01-01

    OBJECTIVES: To examine the frequency and nature of non-fatal asphyxiation and foreign body ingestion injuries among children in the state of Victoria, Australia, and to identify possible areas for prevention. METHODS: For children under 15 years, all Victorian public hospital admissions, July 1987 to June 1995, due to asphyxiation or 'foreign body entering through other orifice' (which includes ingestions), were reviewed. Emergency department presentations due to asphyxiation and foreign body ingestion provided information on circumstances of, and the type of foreign bodies involved in the injuries. RESULTS: The childhood average annual admission rate for asphyxiation was 15.1 per 100,000. Food related asphyxiation peaked in infants under 1 year, and declined to low levels by 3 years. The main foods involved were nuts, carrot, apple, and candy. The rate of non-food related asphyxiation was relatively constant to 3 years of age and then declined by 6 years. Mechanical suffocation was less common. The annual admission rate for 'foreign body entering through other orifice' was 31.7 per 100,000. These injuries peaked in 2-3 year olds then gradually declined. About 80% of these foreign body admissions were ingestions, with coins being the major object ingested. Admission rates for these causes remained constant over the eight years. Asphyxiation resulted in a higher proportion admitted and longer hospital stays. CONCLUSIONS: Prevention of suffocation and strangulation needs to focus on a safe sleeping environment and avoidance of ropes and cords, while foreign body asphyxiation and ingestion needs a focus on education of parents and child carers regarding age, appropriate food, risk of play with coins, and other small items. Legislation for toy small parts could be extended to those used by children up to the age of 5 years, and to other products marketed for children. Design changes and warning labels also have a place in prevention. PMID:9338828

    A case of a ferromagnetic foreign body in a medically compromised patient was reported. The patient was a 45-year-old male who consulted our department complaining of a foreign body accidentally impacted in the right cheek. X-ray examination revealed a foreign body at the lateral aspect of the right mandibular ramus. The removal of the foreign body was scheduled, but the patient did not return for the procedure. After 8 years he revisited our department for the removal of the foreign body, because it had been found to be ferromagnetic and a barrier to MRI examination. X-ray examination confirmed the foreign body was located at the same site as 8 years prior. Although the patient was suffering from liver cirrhosis with thrombocytopenia and leukopenia, the foreign body was successfully removed under general anesthesia. The foreign body was 12 × 5 × 1 mm, weighed 0.48 g, and was ferromagnetic. The patient's postoperative course was uneventful. X-ray examination confirmed the removal of the foreign body. Since the surgery, the patient has been in generally stable condition with no complications. This case was a rare example of a foreign body that needed to be removed for medical examination.

    Detailing the inflammatory mechanisms of biomaterial-implant induced foreign body responses (FBR) has implications for revealing targetable pathways that may reduce leukocyte activation and fibrotic encapsulation of the implant. We have adapted a model of poly(methylmethacrylate) (PMMA) bead injection to perform an assessment of the mechanistic role of the ASC-dependent inflammasome in this process. We first demonstrate that ASC−/− mice subjected to PMMA bead injections had reduced cell infiltration and altered collagen deposition, suggesting a role for the inflammasome in the FBR. We next investigated the NLRP3 and AIM2 sensors because of their known contributions in recognising damaged and apoptotic cells. We found that NLRP3 was dispensable for the fibrotic encapsulation; however AIM2 expression influenced leukocyte infiltration and controlled collagen deposition, suggesting a previously unexplored link between AIM2 and biomaterial-induced FBR.

    BACKGROUND Penetrating and impalement injuries of the hand and fingers are one of the commonest presentations at the hospital’s emergency rooms. This study assessed the characteristics of patients who suffered foreign body injuries to the hands and documented the pattern of diagnosis and management at a specialist plastic surgical facility. METHODS The study was conducted at the Department of Plastic and Reconstructive Surgery, Pakistan Institute of Medical Sciences (PIMS), Islamabad over a period of six years (i.e. from September 1, 2007 to July 31, 2013). All adult patients (37 subjects) of either gender who were managed for hand foreign bodies during the study period were included by convenience sampling technique. The demographic profile of the patients, cause of injury, type of foreign body, occupation of the patient, diagnostic yield of plain x-rays, type of procedure undertaken for retrieval of foreign body, and complications were all recorded on a form. A follow-up of three months was done. RESULTS Eighteen (48.64%) were males while 51.35% (n=19) were female. The mean age was 26.78±9.94 years. The commonest sufferers were housewives 29.72% (n=11). Majority of patients (n=16; 43.24%) presented on day 3 (i.e. >48-72 hours), among the injury causing mechanisms, the commonest were accidents with sewing machines 45.94% (n=17) and sewing machine needles 45.94% (n=17) were the commonest foreign bodies observed. The plain x-ray hands reveled the diagnosis in all patients except those with wooden foreign bodies (n=3; 8.10%). All patients had successful surgical exploration and retrieval of the foreign bodies under local anesthesia and tourniquet control. In two cases, image intensifier was employed to locate the foreign bodies per-operatively. Wound infection was found in 0.8% (n=4) patients, all of whom were managed successfully with oral antibiotics. None of patients had hospitalization. All patients were fine at 3 months follow up.

    Introduction: The phenomenon of neglected foreign bodies is a significant cause of morbidity in soft tissue injuries and may present to dermatologists as delayed wound healing, localized cellulitis and inflammation, abscess formation, or foreign body sensation. Localization and removal of neglected soft tissue foreign bodies (STFBs) is complex due to possible inflammation, indurations, granulated tissue, and fibrotic scar. This paper describes a simple method for the quick localization and (surgical) removal of neglected STFBs using two 23-gauge needles without ultrasonographic or fluoroscopic guidance. Materials and Methods: A technique based on the use of two 23-gauge needles was used in 41 neglected STFBs in order to achieve proper localization and fixation of foreign bodies during surgery. Results: Surgical removal was successful in 38 of 41 neglected STFBs (ranging from 2–13mm in diameter). Conclusion: The cross-needle-guided technique is an office-based procedure that allows the successful surgical removal of STFBs using minimal soft tissue exploration and dissection via proper localization, fixation, and propulsion of the foreign body toward the surface of the skin.

    The series comprises 27 patients examined by CT to detect, locate or exclude a foreign body. 22 of them actually had an orbital foreign body. In three cases CT was the primary method and showed the foreign body correctly, while in 18 it was first detected in plain films and CT was performed to locate it. 20 metallic foreign bodies were hyperdense in appearance. Two cases had wooden foreign bodies, one with a density of +10 HU and the other hypodense with a value of about -434 to -446 HU. The latter piece of wood was first interpreted falsely as a bubble of gas. The results proved that the detection of metal is easy, but differentiation between wood and gas is problematical. Experiments conducted to determine the CT densities of different pieces of wood gave results varying from -618 HU to +23 HU. The highest densities obtained for glass varied from +522 HU to +2000 HU. The density of a plastic lens was -105 HU. PMID:3037632

    Introduction Esophageal foreign bodies are an important and serious cause of morbidity and mortality in both children and adults. Due to the possibility of serious complications, i.e. perforation, necrosis, mediastinitis, and fistulation, rapid and accurate diagnostic measures with subsequent therapy are necessary. Case report We are reporting a case of a 55-year-old, mentally impaired patient that has swallowed a foreign body, which subsequently became lodged in his esophagus. Due to the fact that endoscopic removal was not possible and there was a high risk of complications such as esophageal perforation or mediastinitis in this case, we performed cervical esophagotomy and successfully extracted the foreign body. The patient showed an uneventful postoperative process and could be discharged on Day 11 after the operation. Comprehensive review Furthermore, we performed a systematic review of the literature to identify all studies that described a surgical approach through esophagotomy in cases of foreign body ingestion and found 11 publications describing the cases of 29 patients. These studies reported an overall complication rate of 17.2% and a mortality rate of 0%. Conclusion Our findings suggest that esophagotomy could be a viable approach for the extraction of foreign bodies especially in some cases when endoscopic removal was not successful and the risk of esophageal perforation is high.

    We report a patient who presented with the suspected diagnosis of syphilis. Clinical findings included a penile ulcer, positive history of syphilis more than 20 years ago, and positive syphilis serology (TPHA, FTA-Abs). A biopsy showed a plasma-cell rich inflammation with granuloma formation. Since a birefractory structure was observed in the biopsy possibly corresponding to a foreign body, the patient's occupational exposure was investigated. Working in the fiber reinforced plastics industry, he was heavily exposed to glass fibre that was even detected on the inside of his underwear. Taking the serological pattern into account that was not consistent with active syphilis, a penile ulcer following a foreign body reaction was diagnosed. This case report demonstrates the difficulties of differentiating foreign body granuloma of the genital region from venereal diseases with granuloma formation. Images PMID:9582491

    We report two cases of impression material foreign body in the middle ear. The first case had been affected with chronic otitis media. The silicone flowed into the middle ear through a tympanic membrane perforation during the process of making an ear mold. About 4 years and 8 months after, the patient had severe vertigo and deafness. We found bone erosion of the prominence of the lateral semicircular canal and diagnosed labyrinthitis caused by silicone impression material. In the second case silicone flowed into the canal wall down mastoid cavity. Both cases required surgery to remove the foreign body. The clinical courses in such cases are variable and timing of surgery is sometimes difficult. In addition to reporting these two cases, we present here a review of the literature regarding impression material foreign bodies. PMID:25956272

    The foreign body response is an immune-mediated reaction that can lead to the failure of implanted medical devices and discomfort for the recipient1–6. There is a critical need for biomaterials that overcome this key challenge in the development of medical devices. Here we use a combinatorial approach for covalent chemical modification to generate a large library of variants of one of the most widely used hydrogel biomaterials, alginate. We evaluated the materials in vivo and identified three triazole-containing analogs that substantially reduce foreign body reactions in both rodents and, for at least 6 months, in non-human primates. The distribution of the triazole modification creates a unique hydrogel surface that inhibits recognition by macrophages and fibrous deposition. In addition to the utility of the compounds reported here, our approach may enable the discovery of other materials that mitigate the foreign body response. PMID:26807527

    The case records of 110 patients (97 children and 13 grown-ups) with foreign bodies in the tracheobronchial tree during a period of 14 years (1970-1983) are reviewed. Atypical histories, misleading clinical and radiological findings and delayed diagnoses due to misinterpretations by the patients or their physicians were seen from time to time. Other findings in this survey were that organic material prevailed, with the majority of the objects in the right bronchial tree; there was a male predominance and the most common age for inhalation of a foreign body was about two years. Bronchoscopic extraction was the routine and only in one boy had the object to be removed by the transthoracic route. The venturi technique with oxygenation through the bronchoscope was applied at the extraction procedures. This principle for ventilation during general anaesthesia creates excellent working conditions for the endoscopist. The hazard at the removal of a foreign body is thereby reduced. PMID:3997379

    Biodegradable plates have been used extensively in fracture fixation since the 1960s. They rarely cause stress-protection atrophy or problems requiring secondary plate removal, common complications seen with metallic plates. However, aseptic foreign-body reactions have been reported, sometimes years after the original implantation. Both inadequate polymer degradation and debris accumulation have been implicated as causes. The current generation of commercial biodegradable plates is formulated to minimize this complication by altering the ratio of polylactic and polyglycolic acids. This in vivo study compares the degree of local foreign-body reaction of two commercially available resorbable plates in rabbits. Two types of biodegradable plates were examined: poly(D/L)lactide acid (PDLLA) and polylactide-co-glycolide acid (PLGA). Each plate was placed into a periosteal pericalvarial pocket created beneath the anterior or posterior scalp of a rabbit. Humane killing occurred at 3, 6, and 12 months postoperatively. Foreign-body reaction was evaluated histologically. The PDLLA plates demonstrated marked local foreign-body reactions within the implant capsule as early as 3 months after implantation, with presence of inflammatory cells and granulomatous giant cells in close association with the implant material. All local foreign-body reactions were subclinical with no corresponding tissue swelling requiring drainage. PLGA plates did not demonstrate any signs of inflammatory reactions. In addition, the PLGA plates did not appear to resorb or integrate at 12 months. Neither PDLLA nor PLGA plates demonstrated inflammation of the soft tissue or adjacent bone outside the implant capsule. In our study, the PDLLA plates demonstrated histological evidence of foreign-body reaction that is confined within the implant capsule, which was not seen with the PLGA plates. This finding may be attributable to the lack of significant resorption seen in the PLGA plates. Both PDLLA and PLGA

    Tracheobronchial foreign body aspiration (FBA) is a very common and lethal problem among children. It can easily be diagnosed with a typical history of choking crisis. Clinical examination and radiology play a secondary role in diagnosis. Acute choking episode may lead to death or else to serious sequels such as bronchiectasis, atelectasis, and recurrent pneumonia. Here, we report an interesting case of bronchiectasis in a young female initially thought to be a consequence of pulmonary tuberculosis, who was subsequently found to have retained foreign body in the left lower lobe lung which was the actual cause of her symptoms.

    Navigation surgery in the mandible has rarely been reported because of the complexities of navigating a mobile structure. In this article, we present a simple and novel strategy for removal of a foreign body in the mandible using a navigation system. A female diagnosed with a foreign body in the left mandible underwent navigation surgery using a BrainLAB system. We used a special open splint fabricated with acrylic resin to successfully perform the mandibular navigation. This strategy may be appropriate for many types of mandibular navigation surgery.

    Sharp foreign bodies in the oesophagus may present as an entirely asymptomatic child with only radiological evidence but require emergent surgical management. Safety pins, razor blades and needles are a few of the commonly ingested sharp objects in developing countries. The open safety pin is a particularly interesting clinical problem, as the management depends on its location and orientation. Many methods and instruments have been used over the years to remove them from the upper digestive tract. We present a novel method using the rigid paediatric bronchoscope and alligator forceps for the extraction of this unusual foreign body from the oesophagus of a 6 year old girl. PMID:26851436

    A seven-year-old domestic shorthair cat, adopted 5 years previously with a corneal perforation of the left eye, was presented for investigation of a left orbital mass. Computed tomography revealed a metallic foreign body within a contrast-enhancing, heterogeneous orbital mass. Large cell lymphoma was diagnosed from a fine needle aspirate. The cat staged negatively and was treated with L-asparaginase, prednisolone and three fractions of radiation therapy. A rapid clinical remission was obtained and the cat remained in remission for 3 years after therapy. This is the first report of large cell lymphoma likely occurring secondary to a foreign body.

Flexible nasal endoscopy revealed a lesion which looked suspicious for malignancy and therefore she went onto have a microlaryngoscopy and an attempt at biopsy. It was during this procedure that a foreign body was removed whole from a dilated laryngeal ventricle. We believe that some subtle anatomical changes caused by a pre-existing unilateral vocal cord palsy contributed to the impaction of this foreign body. PMID:25073526

    Wire grill brushes are commonly used for cleaning grill grates. Accidental ingestion of a wire bristle from a grill-cleaning brush is a rarely reported foreign body, with only three prior case reports. Although scarce in the literature, we encountered two pediatric cases at the regional children's hospital within 1 year. By presenting these two cases, our goal was to raise awareness of this potentially hazardous foreign body. Additionally, we raise a consumer safety issue associated with the use of wire grill-cleaning brushes as there are currently no ingestion hazard warnings on these products. Laryngoscope,, 2011.

Examination revealed an edematous, ptotic right upper eyelid with conjunctival hyperemia, proptosis, and significant limitation to upward and downward ductions on the right. MRI was significant for a homogeneously enhancing lesion within the superior rectus muscle. A laboratory evaluation seeking an infectious, inflammatory, or autoimmune process was nonrevealing. A diagnosis of orbital myositis was made, and the patient experienced significant improvement with oral corticosteroids. The patient's symptoms, however, recurred after attempts at a slow taper of the corticosteroids. An orbital biopsy of the lesion revealed fibroadipose tissue containing irregularly shaped yellow-white deposits birefringent under polarized light, suggestive of silica crystals. The patient denied any history of trauma or prior surgery. An intraorbital triamcinolone injection to the superior orbit allowed resolution of symptoms and a successful taper off systemic corticosteroids. PMID:22082591

    The aim of this study was to report a case of acute retinal necrosis (ARN) after intraocular foreign body removal. A 32-year-old male presented with visual loss in the left eye. He was hit by an iron fragment while he was hammering. An intraocular foreign body was found with corneal laceration and traumatic cataract. On the day he was injured, primary closure of the laceration, lensectomy, and vitrectomy were performed, and the foreign body was removed. The day after the operation, there was no sign of retinal detachment or retinitis. Two days after the operation, retinal necrosis and accompanying vitreous inflammation were noted in the far periphery. On day 3, the necrosis spread circumferentially and inflammation became more distinct. ARN was presumed and intravenous acyclovir was administered. The necrotic areas were reduced 2 days later, and were resolved in 1 month. The final visual acuity in his left eye was 20/20 after implantation of an intraocular lens. This case is the first report of ARN after penetrating injury and an intraocular foreign body. ARN may develop after open-globe injury. PMID:23658473

    We report a case of a retained graphite anterior chamber foreign body that was masquerading as stromal keratitis. A 28-year-old male visited with complaints of visual disturbance and hyperemia in his right eye for four weeks. On initial examination, he presented with a stromal edema involving the inferior half of the cornea, epithelial microcysts, and moderate chamber inflammation. Suspecting herpetic stromal keratitis, he was treated with anti-viral and anti-inflammatory agents. One month after the initial visit, anterior chamber inflammation was improved and his visual acuity recovered to 20/20, but subtle corneal edema still remained. On tapering the medication, after three months, a foreign body was incidentally identified in the inferior chamber angle and was surgically removed resulting in complete resolution of corneal edema. The removed foreign body was a fragment of graphite and he subsequently disclosed a trauma with mechanical pencil 12 years earlier. This case showed that the presence of an anterior chamber foreign body should always be considered in the differential diagnosis of idiopathic localized corneal edema. PMID:21461226

    Introduction Esophageal perforation in adults is most frequently caused by ingested foreign bodies. They can migrate through the esophageal wall, damaging the nearby organs such as the aorta or the trachea, with fatal outcome. After the diagnosis, the viable treatments for extracting the foreign body and repairing the perforation are several. The appropriate treatment, may be endoscopic, surgical or combined, depending on the level of the perforation, on the co-morbidities of the patient and on the available resources. Presentation of case This paper describes a case of a 68 years old patient with a double EP caused by a meat-bone that perforated the thoracic esophageal wall, approaching the aorta on the left side and the azygos vein on the right side. Discussion Because of the double transfixion and the position near the aorta and the azygos, it was not possible to remove safely the bone during the endoscopy. The management required a combined endoscopic and surgical approach. This way it was possible to detect easily the location of the perforation, to remove safely the foreign body, to repair the perforation both from the outside and from the inside, and to place the nasogastric tube under direct vision. Conclusion Even when the type of esophageal perforation requires surgical treatment, the simultaneous use of endoscopy proved to be an advantage in order to extract the foreign body safely, to perform a double repair of the perforation and to place the nasogastric tube under direct vision.

    Foreign bodies are often encountered by oral and maxillofacial surgeons and may present a diagnostic challenge to the trauma surgeon due to many factors such as the size of the object, the difficult access, and a close anatomic relationship of the foreign body to vital structures. They are usually a result of injuries or operations. Fragments of broken instruments can be left behind and entire teeth or their fragments can be displaced during extraction. The approach to this kind of injury should be sequential and multidisciplinary, beginning with the trauma unit that will provide maintenance of the airways, hemodynamic stabilization, and, but only if necessary, neurologic, ophthalmologic, and vascular evaluation. With a view to illustrating and discussing the diagnosis and treatment of this kind of injury, this study reports impacted foreign bodies in oral and maxillofacial region. The following data were collected: age, sex, race, etiology, occurrence of fracture, anatomic location of the fracture, daytime of the traumatic event, type of the object, signal and symptoms, type of imaging examination used, type of anesthesia, approach, transoperative complication, period between surgery and hospital liberation, and the occurrence of death. Foreign body injuries in the maxillofacial region can place the patient's life at risk, so a correct initial treatment performed by a multidisciplinary team increases the survival of this kind of patient.

    A 52-year-old man sustained a laceration to his left eyebrow after a fall in his bathroom. His plastic glasses shattered upon impact. The patient was referred to a local emergency department. After a quick exploration by the physician on call, the wound was closed by a nurse using the Steri-Strip Wound Closure system. No further exploration or imaging was performed. Four weeks after the incident the patient presented to a dermatologist with a "foreign body sensation" at the site of the laceration. Assuming a foreign body granuloma, he was referred to a maxillofacial surgeon who removed plastic debris (parts of the glasses worn by the patient). The wound subsequently healed without further complications.The patient filed a complaint for inadequate treatment in the emergency department. No detailed patient and accident history had been obtained, the wound exploration performed by the physician was superficial, and the wound closure was performed by a nurse. The expert opinion of the arbitration board ascertained a medical malpractice in terms of insufficient history, examination, and a lack of documentation. Specific questioning of the accident history would have led to the suspicion of possible foreign bodies, thus, leading to a more thorough exploration and likely further imaging. The arbitration board concluded that obtaining a detailed accident history and an accurate examination would have revealed the foreign bodies and/or led to further imaging. Complying with this, the patient could have been spared further harm and secondary surgery would have been unnecessary. PMID:24474417

    The ingestion of foreign bodies is a worldwide pediatric pathology. We assessed the clinical, endoscopic, and therapeutic aspects of this condition in a pediatric gastroenterology unit. We reviewed 61 patients (median age of 3.25 ± 4.7 years). The most frequently ingested objects were coins (26.23%), unidentified metal objects (13.11%), bones (8.19%), batteries, and buttons (6.55%). The clinical features we encountered included abdominal pain (55.73%), vomiting (34.42%), and asymptomatic children (29.5%). Routine X-ray examination enabled finding the foreign body in 42 of the cases. An esophagogastroduodenoscopy was performed within 24–72 hours. 25 cases resulted in a negative endoscopy (40.98%), 19 objects (31.14%) were removed using a polypectomy snare, and extraction failure occurred in 17 patients (27.86%). 28 foreign bodies were passed without incidents; in 14 cases, the swallowed objects were never found. In one case, a battery was stuck in the esophageal folds and led to tracheal-esophageal fistula and bronchopneumonia and later to esophageal stenosis. We report a large proportion of foreign bodies that could not be identified or removed due to lack of early endoscopy and poor technical settings. Batteries and sharp objects lead to severe complications and preschool-age children are at high risk for such events. PMID:26949384

    We report a case of recurring foreign bodies in the urinary bladder. A 67-year-old male inserted a foreign body into the urinary bladder during masturbation. Eight months later, he experienced a fever and went to a hospital where ultrasonography revealed a foreign body in his urinary bladder. Then, he was referred to our hospital for surgical treatment. The patient's surgical record indicated that he had undergone the same operation 3 times in the past thirty years. The inserted foreign body was successfully removed by suprapubic cystotomy, and he was discharged 13 days after the operation. He was also evaluated by psychiatrists, but they diagnosed that he had no mental disorder. To our knowledge, this is the first report on the removal of a foreign body in the urinary bladder four times in the same patient. PMID:27133888

    We report the case of a patient who developed sarcoid granulomas 11 months after starting treatment with pegylated interferon alfa and ribavirin for chronic hepatitis C. The sites of the lesions were related to 3 different foreign bodies: silica in old scars on the skin, hyaluronic acid that had been injected into facial tissues, and silicone in an axillary lymph node draining the area of a breast implant. Systemic sarcoidosis was diagnosed on the basis of a history of dry cough and fever and blood tests that revealed elevated angiotensin converting enzyme and liver enzymes. Interruption of the antiviral therapy led to normalization of liver function tests and disappearance of the skin lesions and lymphadenopathies. Dermatologists and cosmetic surgeons should be aware of the risk of sarcoid lesions related to cosmetic implants in patients who may require treatment with interferon in the future. PMID:22995946

    We report a fatal case of gastrointestinal perforation and hemorrhage secondary to the ingestion of a foreign body. While engaged in an amateur futsal competition, an apparently healthy young man suddenly collapsed and his respiration ceased. Autopsy revealed a 3-mm circular perforation on the gastric wall fundus with a significant amount of clotted blood within the gastric lumen. On inspection, a foreign body consisting of a bristle-like hair, later identified via electron microscopy to be a cat vibrissa, i.e. a whisker, was found along the perforation margin. Thus, the inadvertent ingestion of fine, sharp objects (even a cat whisker) can lead to gastric perforation and bleeding, which might prove fatal under given circumstances. PMID:27183326

    A 13-year-old boy with no previous history of foreign body aspiration, presenting with side pain, was referred to our clinic with a pneumonia diagnosis by an external medical facility where he had been started on antibiotic treatment. Consolidation in the right inferior lobe and minimal pleural effusion were found on the lung radiograph and computed tomography scan. Skin hyperemia and abscess formation in the right chest were observed subsequently. A drain was placed; bronchoscopy, sampling for cultures, and a biopsy were performed. Four months after this first episode ended with inconclusive results, the patient returned, reporting that a spike of grass was protruding from the continued abscess drainage. The skin lesion closed after emptying of the abscess cavity; a check-up bronchoscopy was unremarkable. The extrusion from the skin of the foreign body, a rare event in the published literature, was our first such case. PMID:26652568

    Introduction Self-inflicted foreign bodies in the male urethra and urinary bladder are an emergency that urologists may rarely have to face. A case of an electrical wire inserted in the male urethra and coiled in the bladder is presented. Case presentation A 53-year-old male presented with the inability to void and bloody urethral discharge after having introduced an electrical wire in his urethra for masturbation 3 hours earlier. He had made several unsuccessful attempts to remove it. Conclusion The variety of these objects may be impressive and removal of the foreign body may be quite challenging requiring imagination and high-level surgical skills., In this case an electrical wire was used and the diagnostic as well as the therapeutic steps for its removal are presented.

    The authors present a patient with a presumed diagnosis of Crohn's disease for 6 years turning out to be an unusual inflammatory mass caused by ileal perforation due to a foreign body. When surgical intervention became necessary for admissions with recurrent obstruction, laparoscopy revealed an inflammatory mass in the terminal ileum, exposing two pieces of plastic bearing the word ‘Heinz’. Resection of the inflammatory mass led to the complete resolution of symptoms. Histology from the operative specimen showed no features of Crohn's disease. There were no granulomas and no fissuring ulcers. This case highlights that an inflammatory mass in the small intestine caused by the perforation of ingested foreign body can mimic Crohn's disease. To our knowledge, this is the first report of a synthetic plastic packaging causing ileo-caecal junctional perforation mimicking Crohn’s disease. PMID:23749825

    Patients with autism often find admission to hospital an anxious time. Awareness of the condition, a speedy diagnosis and flexibility in adapting treatment plans will facilitate early discharge and return to their familiar environment. We describe a patient with severe autism who presented with an acute abdomen secondary to ingestion of a foreign body which required laparotomy. Communication directly to medical staff was greatly limited due to severe autism and close liaison with family members was essential in interpreting scant clinical signs. At the time of surgery a rubber bottle teat was found causing transection of small bowel due to erosion of the foreign body. The postoperative course was fraught with challenges and ensuring side room nursing care with family members present throughout his admission minimised postoperative stress and confusion. We recommend awareness of management strategies for patients with autism to ensure rapid recovery and early discharge home. PMID:24966264

  2. Foreign body detection in food materials using compton scattered x-rays

    NASA Astrophysics Data System (ADS)

    McFarlane, Nigel James Bruce

    This thesis investigated the application of X-ray Compton scattering to the problem of foreign body detection in food. The methods used were analytical modelling, simulation and experiment. A criterion was defined for detectability, and a model was developed for predicting the minimum time required for detection. The model was used to predict the smallest detectable cubes of air, glass, plastic and steel. Simulations and experiments were performed on voids and glass in polystyrene phantoms, water, coffee and muesli. Backscatter was used to detect bones in chicken meat. The effects of geometry and multiple scatter on contrast, signal-to-noise, and detection time were simulated. Compton scatter was compared with transmission, and the effect of inhomogeneity was modelled. Spectral shape was investigated as a means of foreign body detection. A signal-to-noise ratio of 7.4 was required for foreign body detection in food. A 0.46 cm cube of glass or a 1.19 cm cube of polystyrene were detectable in a 10 cm cube of water in one second. The minimum time to scan a whole sample varied as the 7th power of the foreign body size, and the 5th power of the sample size. Compton scatter inspection produced higher contrasts than transmission, but required longer measurement times because of the low number of photon counts. Compton scatter inspection of whole samples was very slow compared to production line speeds in the food industry. There was potential for Compton scatter in applications which did not require whole-sample scanning, such as surface inspection. There was also potential in the inspection of inhomogeneous samples. The multiple scatter fraction varied from 25% to 55% for 2 to 10 cm cubes of water, but did not have a large effect on the detection time. The spectral shape gave good contrasts and signal-to-noise ratios in the detection of chicken bones.

    Osteoclasts and foreign body giant cells (FBGCs) are both derived from the fusion of macropahges. These cells are seen in close proximity during foreign body reactions, therefore it was assumed that they might interact with each other. The aim was to identify important genes that are expressed by osteoclasts and FBGCs which can be used to understand peri-implantitis and predict the relationship of these cells during foreign body reactions. Bone marrow macrophages (BMM) were treated with receptor activator of nuclear factor kappa B ligand (RANKL) to produce osteoclasts. Quantitative PCR (qPCR) was used to identify the genes that were expressed by osteoclasts and FBGCs compared to macrophage controls. TRAP staining was used to visualise the cells while gelatine zymography and western blots were used for protein expression. Tartrate-resistant acid phosphatase (TRAP), matrix metallo proteinase 9 (MMP9), nuclear factor of activated T cells 1 (NFATc1), cathepsin K (CTSK) and RANK were significantly lower in FBGCs compared to osteoclasts. Inflammation specific chemokines such as monocyte chemotactic protein (MCP1 also called CCL2), macrophage inflammatory protein 1 alpha (MIP1α), MIP1β and MIP1γ, and their receptors CCR1, CCR3 and CCR5, were highly expressed by FBGCs. FBGCs were negative for osteoclast specific markers (RANK, NFATc1, CTSK). FBGCs expressed chemokines such as CCL2, 3, 5 and 9 while osteoclasts expressed the receptors for these chemokines i.e. CCR1, 2 and 3. Our findings show that osteoclast specific genes are not expressed by FBGCs and that FBGCs interact with osteoclasts during foreign body reaction through chemokines. PMID:24500983

The tip was machined to a 20-gauge cylinder that can be inserted readily into the eye either through an entrance wound or through a pars plana incision. Placement of the tip of the magnet inside the eye allows the foreign body to impact the tip of the magnet rather than the wall of the eye. PMID:2916983

    Introduction. Foreign bodies (FBs) in the aerodigestive tract are important causes of morbidity and mortality and pose diagnostic and therapeutic challenges. The best method of removal of an esophageal and tracheobronchial FB is endoscopic guided extraction. Objective. To present our experience of the removal of aerodigestive FBs in adult Ethiopian patients using rigid endoscopes. Methods. A hospital-based prospective study, at Tikur Anbessa Referral and Teaching Hospital, from January 2011 to December 2012 (over two years). Results. A total of 32 patients (18 males and 14 females) with a mean age of 28.0 ± 12.74 years were treated for FB ingestion and aspiration at Tikur Anbessa Hospital. The FBs were impacted at the esophagus in 18 (56.2%) patients, at the pharynx in 7 (21.8%), and at the air way in 7 (21.8%) patients. Pieces of bones were the commonest objects found in the esophagus (17/18 of the cases) and the pharynx (4/7), while fractured tracheostomy tubes and needles were frequently seen in the air way (3/7 cases each). The foreign bodies were visible in plain radiographs of 26 (81.2%) patients. Successful extraction of FBs was achieved by using Mc gill forceps in 11 cases, rigid esophagoscopes in 9 patients, and bronchoscopes in 4 cases. Four cases required open surgery to remove the foreign bodies. Two complications (one pneumothorax and one esophageal perforation) occurred. All patients were discharged cured. Discussion and Recommendations. Aerodigestive FBs are not so rare in the hospital and timely diagnosis and removal of accidentally ingested and aspirated foreign body should be performed so as to avoid the potentially lethal complications associated. Rigid esophagoscopy requires general anesthesia and is associated with its own complications, but our experience and outcome of its use are encouraging. PMID:24834074

    A new species in the family Enterobacteriaceae, Escherichia vulneris, was characterized by the Centers for Disease Control and Prevention in 1982. It has been shown to have a predilection for human wounds, and several case reports have described superficial wound infections with this rare organism. Until now, however, there have been no reports of osteomyelitis occurring secondary to E vulneris infection. The authors present the case of a 13-year-old boy who fell on a stick and sustained a penetrating injury to his right knee. Radiographs and magnetic resonance imaging revealed a lytic lesion with a foreign body in the tibial epiphysis. On culture, only E vulneris was found, and histologic examination showed the foreign body to be surrounded by acute and chronic inflammation, abscess formation, and foreign-body giant-cell reaction. Although a recent study questioned the pathogenicity of this organism after reviewing the cases of 12 patients in whom there was concurrent heavy growth of Staphylococcus aureus, the present case supports the finding that E vulneris is a human pathogen that should be treated when obtained from human wound cultures.

    Background Bioabsorbable plates and screws are commonly used to reduce maxillofacial bones, particularly in pediatric patients because they degrade completely without complications after bone healing. In this study, we encountered eight cases of a delayed foreign body reaction after surgical fixation with bioabsorbable plates and screws. Methods A total of 234 patients with a maxillofacial fracture underwent surgical treatment from March 2006 to October 2013, in which rigid fixation was achieved with the Inion CPS (Inion, Tampere, Finland) plating system in 173 patients and Rapidsorb (Synthes, West Chester, PA, USA) in 61 patients. Their mean age was 35.2 years (range, 15-84 years). Most patients were stabilized with two- or three-point fixation at the frontozygomatic suture, infraorbital rim, and anterior wall of the maxilla. Results Complications occurred in eight (3.4%) of 234 patients, including palpable, fixed masses in six patients and focal swelling in two patients. The period from surgical fixation to the onset of symptoms was 9-23 months. Six patients with a mass underwent secondary surgery for mass removal. The masses contained fibrous tissue with a yellow, grainy, cloudy fluid and remnants of an incompletely degraded bioabsorbable plate and screws. Their histological findings demonstrated a foreign body reaction. Conclusions Inadequate degradation of bioabsorbable plates caused a delayed inflammatory foreign body reaction requiring secondary surgery. Therefore, it is prudent to consider the possibility of delayed complications when using bioabsorbable plates and surgeons must conduct longer and closer follow-up observations. PMID:26848444

    We present a case report in which a 4-year-old girl was involved in a fall that resulted in an injury of the right orbita. The girl kept a chopstick in her right hand that got into the right orbita due to this accident. Only a fraction remained in the orbita; the residual chopstick got lost. Hence, the substance of the chopstick was unknown. Computed tomography (CT) revealed a foreign body in the right orbita, but ophthalmologists had initially no indication of intervention. Further course according to the follow-up CT showed an increase of Hounsfield units (HU). These findings led to the assumption that the foreign body was made of wood. Through this, the ophthalmologists performed an evacuation. Motivated by these clinical results, we created an experimental setup that could demonstrate changes of HU in different coated chopsticks. It is concluded that wooden foreign bodies can display a variety of CT appearances depending on materials, types, coating, and time-course. PMID:17347767

    The purpose of the study was to compare two similar foreign body retrieval devices, the Texan{sup TM} (TX) and the Texan LONGhorn{sup TM} (TX-LG), in a swine model. Both devices feature a {<=}30-mm adjustable loop. Capture times and total procedure times for retrieving foreign bodies from the infrarenal aorta, inferior vena cava, and stomach were compared. All attempts with both devices (TX, n = 15; TX-LG, n = 14) were successful. Foreign bodies in the vasculature were captured quickly using both devices (mean {+-} SD, 88 {+-} 106 sec for TX vs 67 {+-} 42 sec for TX-LG) with no significant difference between them. The TX-LG, however, allowed significantly better capture times than the TX in the stomach (p = 0.022), Overall, capture times for the TX-LG were significantly better than for the TX (p = 0.029). There was no significant difference between the total procedure times in any anatomic region. TX-LG performed significantly better than the TX in the stomach and therefore overall. The better torque control and maneuverability of TX-LG resulted in better performance in large anatomic spaces.

    Gossypibomas are foreign objects, usually surgical sponges or towels, accidentally retained in the human body during an operation. They are associated with significant postsurgical complications, morbidity and mortality. Postsurgical radiographs are considered the standard of care for a retained foreign body, but their detection sensitivity typically ranges between 60% and 80%. To address this we have microfabricated x-ray visible microtags that can be attached to foreign bodies and allow them to be easily recognized by a trained radiologist or a computer aided detection (CAD) algorithm. Key element of the microtag design is the use of three radiopaque beads placed in a precise, triangular configuration. We demonstrated that those microtags are visible in standard radiographs over different backgrounds (soft tissue, bone) and at different spatial orientations. We envision that these microtags attached to surgical sponges and towels will greatly increase the detection sensitivity and specificity of gossypibomas at an infinitesimal cost and will be used in the operating room to provide point of care information to the surgeons.

    Background: Foreign body aspiration (FBA) is a significant cause of airway distress, mortality, and morbidity in children. Diagnosis of FBA can be challenging and is sometimes delayed for weeks or even months. If not diagnosed and treated promptly, FBA can result in serious consequences. Methods: For this retrospective study, we investigated the medical records of 89 children who underwent bronchoscopy for suspected FBA and recorded relevant demographic, clinical, and treatment data. Results: Of the 89 patients identified for this study, 51 had a definitive diagnosis of FBA. Among these patients, choking, chronic cough and wheezing, cyanosis, and dyspnea were the most frequent symptoms of FBA. The foreign bodies were located in the left bronchus (45.1%), the right bronchus (35.3%), the trachea (15.7%), and in both the right and left bronchi (3.9%). Seeds were the most prevalent foreign body, found in 39.2% of the patients. Conclusion: Lack of complete medical history in patients with suspected FBA is one of the main causes of delayed FBA diagnosis. Bronchoscopy is considered the definitive diagnostic method for FBA and should be conducted in all patients with suspected FBA because of the low risk of complications and reduced probability that FBA diagnosis and treatment will be delayed.

    In recent years, a variety of devices (drug-eluting stents, artificial organs, biosensors, catheters, scaffolds for tissue engineering, heart valves, etc.) have been developed for implantation into patients. However, when such devices are implanted into the body, the body can react to these in a number of different ways. These reactions can result in an unexpected risk for patients. Therefore, it is important to assess and optimize the biocompatibility of implantable devices. To date, numerous strategies have been investigated to overcome body reactions induced by the implantation of devices. This review focuses on the foreign body response and the approaches that have been taken to overcome this. The biological response following device implantation and the methods for biocompatibility evaluation are summarized. Then the risks of implantable devices and the challenges to overcome these problems are introduced. Specifically, the challenges used to overcome the functional loss of glucose sensors, restenosis after stent implantation, and calcification induced by implantable devices are discussed.

    1960-01-01

    Measurements of average skin friction of the turbulent boundary layer have been made on a 15deg total included angle cone with foreign gas injection. Measurements of total skin-friction drag were obtained at free-stream Mach numbers of 0.3, 0.7, 3.5, and 4.7 and within a Reynolds number range from 0.9 x 10(exp 6) to 5.9 x 10(exp 6) with injection of helium, air, and Freon-12 (CCl2F2) through the porous wall. Substantial reductions in skin friction are realized with gas injection within the range of Mach numbers of this test. The relative reduction in skin friction is in accordance with theory-that is, the light gases are most effective when compared on a mass flow basis. There is a marked effect of Mach number on the reduction of average skin friction; this effect is not shown by the available theories. Limited transition location measurements indicate that the boundary layer does not fully trip with gas injection but that the transition point approaches a forward limit with increasing injection. The variation of the skin-friction coefficient, for the lower injection rates with natural transition, is dependent on the flow Reynolds number and type of injected gas; and at the high injection rates the skin friction is in fair agreement with the turbulent boundary layer results.

    Anterior gastrointestinal tract obstruction by a foreign body has been reported in several avian species, most commonly in captive birds. It is often associated with behavioral issues that lead to compulsive consumption of bedding materials or bright moving objects. In penguins, foreign bodies are most commonly identified at necropsy and often are found in the ventriculus because of anatomic characteristics of the species. A captive African black-footed penguin ( Spheniscus demersus ) was diagnosed with a ventricular foreign body. The anatomic and physiologic differences that should be taken into account when surgically removing a ventricular foreign body in a penguin are described. These differences include the caudal location in the coelom and the large size of the ventriculus in proportion to the penguin's body size; the presence of a simple stomach, uniform in thickness and lacking muscular development; a simple gastrointestinal cycle (gastric contraction); and variability in pH of stomach contents. No complications were observed after surgery, and the bird recovered completely. Management of foreign bodies in birds should be based on the clinical signs of the individual bird, the species affected and its anatomic characteristics, the nature and location of the foreign body, available tools, and the preference and experience of the surgeon. This particular case demonstrates that the most indicated and preferred method is not always possible and that knowledge of biologic, anatomic, and physiologic differences of the species may allow the use of an alternative and more invasive approach with favorable outcomes.

    2009-01-01

    A biologically inspired spiking neural network model, called pulse-coupled neural networks (PCNN), has been applied in an automatic inspection machine to detect visible foreign particles intermingled in glucose or sodium chloride injection liquids. Proper mechanisms and improved spin/stop techniques are proposed to avoid the appearance of air bubbles, which increases the algorithms' complexity. Modified PCNN is adopted to segment the difference images, judging the existence of foreign particles according to the continuity and smoothness properties of their moving traces. Preliminarily experimental results indicate that the inspection machine can detect the visible foreign particles effectively and the detection speed, accuracy and correct detection rate also satisfying the needs of medicine preparation.

    The radiological determination of foreign objects in corpses can be difficult if they are fragmented or deformed. With multislice computed tomography, radiodensities--referred to as Hounsfield units (HU)--can be measured. We examined the possibility of differentiating 21 frequently occurring foreign bodies, such as metals, rocks, and different manmade materials by virtue of their HU values. Gold, steel, and brass showed mean HU values of 30671-30710 (upper measurable limit), mean HU values for steel, silver, copper, and limestone were 20346, 16949, 14033, and 2765, respectively. The group consisting of objects, such as aluminum, tarmac, car front-window glass, and other rocks, displayed mean HU values of 2329-2131 HU. The mean HU value of bottle glass and car side-window glass was 2088, whereas windowpane glass was 493. HU value determination may therefore help in preautopsy differentiation between case-relevant and irrelevant foreign bodies and thus be useful for autopsy planning and extraction of the objects in question.

    We report here the successful removal of a retrobulbar metallic foreign body in a patient with penetrating ocular trauma by a transconjunctival approach and combination management with C-arm fluoroscopy and extraocular muscle severance. A 37-year-old man sustained a penetrating injury to the right eye while using an iron hammer. Initial slitlamp examination revealed a corneoscleral laceration, iridocele, anterior chamber collapse, and a traumatic cataract. Visual acuity in the right eye was limited to the perception of hand motion. Computed tomography revealed an orbital foreign body in the retrobulbar area. The patient underwent corneoscleral suturing, severance of extraocular muscles, removal of the foreign body with guidance by C-arm fluoroscopy, pars plana lensectomy, and pars plana vitrectomy. Combination management with C-arm fluoroscopy and extraocular muscle severance may thus be a suitable approach to the removal of a retrobulbar metallic foreign body. PMID:27070785

    Skin is well recognized as an important somatic mirror of one's emotion and a site for the discharge of one's anxieties. We present a case of a 42-year-old female patient presenting with a vague history of generalized body pain and skin lesions in the form of cotton threads buried under the skin, crusted plaque, multiple keloids and rusted pin buried through the skin mostly in the easily accessible areas of the body. Histopathology from the crusted plaque revealed foreign body granuloma. To satisfy her psychological or emotional need, it is the deliberate and conscious production of self-inflicted skin lesions through overvalued ideation of acupuncture on her part. PMID:19915244

    We previously demonstrated that myeloid cells are the source of fibrotic tissue induced by foreign material implanted in the peritoneal cavity. This study utilised the MacGreen mouse, in which the Csf1r promoter directs myeloid-specific enhanced green fluorescent protein (EGFP) expression, to determine the temporal gene expression profile of myeloid subpopulations recruited to the peritoneal cavity to encapsulate implanted foreign material (cubes of boiled egg white). Cells with high EGFP expression (EGFP(hi)) were purified from exudate and encapsulating tissue at different times during the foreign body response, gene expression profiles determined using cDNA microarrays, and data clustered using the network analysis tool, Biolayout Express(3D). EGFP(hi) cells from all time points expressed high levels of Csf1r, Emr1 (encoding F4/80), Cd14 and Itgam (encoding Mac-1) providing internal validation of their myeloid nature. Exudate macrophages (days 4-7) expressed a large cluster of cell cycle genes; these were switched off in capsule cells. Early in capsule formation, Csf1r-EGFP(hi) cells expressed genes associated with tissue turnover, but later expressed both pro- and anti-inflammatory genes alongside a subset of mesenchyme-associated genes, a pattern of gene expression that adds weight to the concept of a continuum of macrophage phenotypes rather than distinct M1/M2 subsets. Moreover, rather than transdifferentiating to myofibroblasts, macrophages contributing to later stages of the peritoneal foreign body response warrant their own classification as 'fibroblastoid' macrophages.

    Treatment with low-amperage (200 microA) electrical current was compared to intravenous doxycycline treatment or no treatment in a rabbit model of Staphylococcus epidermidis chronic foreign body osteomyelitis to determine if the electricidal effect is active in vivo. A stainless steel implant and 10(4) CFU of planktonic S. epidermidis were placed into the medullary cavity of the tibia. Four weeks later, rabbits were assigned to one of three groups with treatment administered for 21 days. The groups included those receiving no treatment (n = 10), intravenous doxycycline (n = 14; 8 mg/kg of body weight three times per day), and electrical current (n = 15; 200 microA continuous delivery). Following treatment, rabbits were sacrificed and the tibias quantitatively cultured. Bacterial load was significantly reduced in the doxycycline (median, 2.55 [range, 0.50 to 6.13] log10 CFU/g of bone) and electrical-current (median, 1.09 [range, 0.50 to 2.99] log10 CFU/g of bone) groups, compared to the level for the control group (median, 4.16 [range, 3.70 to 5.66] log10 CFU/g of bone) (P < 0.0001). Moreover, treatment with electrical current was statistically significantly more efficacious (P = 0.035) than doxycycline treatment. The electricidal effect (the bactericidal activity of low-amperage electrical current against bacterial biofilms) is active in vivo in the treatment of experimental S. epidermidis chronic foreign body osteomyelitis.

    Foreign body ingestions in children are some of the most challenging clinical scenarios facing pediatric gastroenterologists. Determining the indications and timing for intervention requires assessment of patient size, type of object ingested, location, clinical symptoms, time since ingestion, and myriad other factors. Often the easiest and least anxiety-producing decision is the one to proceed to endoscopic removal, instead of observation alone. Because of variability in pediatric patient size, there are less firm guidelines available to determine which type of object will safely pass, as opposed to the clearer guidelines in the adult population. In addition, the imprecise nature of the histories often leaves the clinician to question the timing and nature of the ingestion. Furthermore, changes in the types of ingestions encountered, specifically button batteries and high-powered magnet ingestions, create an even greater potential for severe morbidity and mortality among children. As a result, clinical guidelines regarding management of these ingestions in children remain varied and sporadic, with little in the way of prospective data to guide their development. An expert panel of pediatric endoscopists was convened and produced the present article that outlines practical clinical approaches to the pediatric patient with a variety of foreign body ingestions. This guideline is intended as an educational tool that may help inform pediatric endoscopists in managing foreign body ingestions in children. Medical decision making, however, remains a complex process requiring integration of clinical data beyond the scope of these guidelines. These guidelines should therefore not be considered to be a rule or to be establishing a legal standard of care. Caregivers may well choose a course of action outside of those represented in these guidelines because of specific patient circumstances. Furthermore, additional clinical studies may be necessary to clarify aspects based on

    Reproducible animal models of osteomyelitis close to the clinical scenario are difficult to obtain as the animals either die shortly after inoculation of bacteria or the bone cures itself of infection. Additional materials used as foreign bodies offer increased chances for localized infection due to bacterial attachment and are closer to clinical pathology. Through in vivo experimentation we investigated here the influence of surface area of a series of foreign bodies on the final outcome of the animal model, in terms of reproducibility, survival rate and time necessary for onset of chronic disease. Stainless steel Kirschner wire segments, stainless steel balls and cotton meshes were employed for this purpose. The clinical, microbiological, radiological and histological results obtained were compared with the simple case where no foreign body was used. The follow-up period was 57days. The cotton meshes, which had the highest surface area, were observed to provide the best outcome, with the lowest disease onset time interval (of 1week earlier than the others), the highest survival (of 90%) and disease reproduction rate (90%). The only clinical pattern of the mesh group rabbits was short lived inflammation while the other rabbits presented also some other clinical signs such as rhinorrheas, abscesses, rush and/or dyspnea. Moreover, this model is the most suitable for further treatment studies, as the cotton meshes could be easily removed after disease onset, without any intervention on the bone. This is important, as the treatment would address the bacteria present within the bone parts (marrow, cortex, periosteum etc.) not those forming the biofilm. PMID:27264239

    Introduction  Foreign body in airway is a common emergency in ENT practice. As we know, Rigid Bronchoscopy is the method of choice for removing it, although at times it leads to specialists performing unnecessary bronchoscopy, exposing patients to hazards of general anesthesia. Objective  The objective of my study is to calculate sensitivity, specificity, positive predictive value, odds ratio from the clinical and radiological signs, comparing with the gold standard, the rigid bronchoscope procedure. Method  This is a prospective analytical study designed at University Teaching Hospital and conducted over a period of 18 months, from March 2011 to August 2012. Data collection was broadly classified into three different categories: (1) Symptomatology, such as presence or absence of choking, cyanosis, and difficulty in breathing; (2) Clinical signs, such as the presence or absence of air entry, crackles, and rhonchi 3. Chest X-ray findings were suggestive of a foreign body. Results  There were a total of 40 rigid bronchoscopies performed under general anesthesia for the diagnosis and therapeutic reasons. Among 40 patients who underwent rigid bronchoscopy, 32 (80%) were found to have varieties of foreign bodies in their airway while 8 patients (20%) had negative bronchoscopy. The history of choking is the only clinical symptoms which came out to be statistically Significant (p = 0.043) with odds ratio of 5. Conclusion  Rigid bronchoscopy is the gold standard technique for diagnosis and procedure of choice to remove FB from airway. Regardless, it still presents a small chance of negative result, especially when there is no history of aspiration. PMID:27413398

    Anterior urethral valve (AUV) is a long known but rare anomaly, which is occasionally encountered in boys with obstructive uropathy. We present a case of AUV with a diverticulum which was misdiagnosed at other center as neurogenic bladder resulting in chronic renal failure. The case was further complicated by breakage of tip of the catheter used for clean intermittent catheterization (CIC) in the diverticulum presenting as a foreign body in the urethra. This article highlights the frequently missed diagnosis of AUV by most practitioners wrongly labeling it as neurogenic bladder, leading to improper management and renal failure in young boys.

    Eye injuries from foreign body incidents remain prevalent in the workplace setting. Often the professional nurse provides the first line of treatment. The informal class presented at the authors' facility offered a comprehensive, organized presentation of a common injury encountered in the practice of occupational health nursing. Strenghts of the presentation included handouts demonstrating eye eversion technique and a flip chart summarizing the content to be placed in each medical station as quick reference. One challenge involved presenting the information to all nurses. The site encompasses four locations and some nurses function as the only staff in the plant for a given shift. With the support of administration and some creative scheduling, 10 of 17 nurses attended one of three classes offered in one morning, and the remaining 7 were able to view the class on videotape. Videotaping the presentation also provided material for future orientation, as well as an opportunity for review. Overall analysis found this a worthwhile offering relevant to practice. A brief formal written evaluation indicated the objectives for the class were achieved and elicited subjects for future topics. Informal chart reviews to check for documentation of visual acuity testing and eversion of the upper lid for foreign body injuries is another outcome measure currently in progress. In addition, a performance improvement project could be accomplished easily by retrospective chart review of assessment and treatment documentation, and tracking of revisits and referrals. Knowledge of current standards in the assessment, first aid, and treatment of eye injuries is every occupational health nurse's responsibility. However, prevention of foreign body injuries is far superior to any treatment modality available. As highly visible leaders within the occupational setting, nurses can be advocates and role models for safe work practices. Occupational health nurses may promote safe eye practices by

    Implanted materials including drug delivery devices and chemical sensors undergo what is termed the foreign body reaction (FBR). Depending on the device and its intended application, the FBR can have differing consequences. An extensive scientific research effort has been devoted to elucidating the cellular and molecular mechanisms that drive the FBR. Important, yet relatively unexplored, research includes the localized tissue biochemistry and the chemical signaling events that occur throughout the FBR. This review provides an overview of the mechanisms of the FBR, describes how the FBR affects different implanted devices, and illustrates the role that microdialysis sampling can play in further elucidating the chemical communication processes that drive FBR outcomes.

    Adult foreign body (FB) aspiration is an uncommon but potentially fatal event. Options for extraction include flexible bronchoscopy (FLXB), rigid bronchoscopy (RB), and surgical extraction. We report the case of a large, smooth aspirated rock causing airway obstruction in an elderly male. RB is generally the preferred approach for extraction of a large complex FB; however, due to its size, the FB had to be removed using FLXB combined with an endobronchial blocker. In this report, we describe the anesthetic and surgical considerations and the novel technique used to extract the FB. PMID:27274879

    To asses the role of bronchoscopy and its yield in children with respiratory symptoms and no typical history of radiological evidence of foreign body aspiration (FBA), we reviewed the records of all patients who underwent bronchoscopy at our institution between 1985 and 1995 and had no history of choking, witnessed FBA or clear radiological evidence of FBA (N = 54, age range 4 months to 16 years). These were subdivided into two subgroups, those with positive bronchoscopy, and those with negative bronchoscopy. Respiratory symptoms and their duration, signs and radiological findings did not differ in both subgroups. PMID:11330222

    Nonthrombotic pulmonary embolism is defined as embolization to the pulmonary circulation caused by a wide range of substances of endogenous and exogenous biological and nonbiological origin and foreign bodies. It is an underestimated cause of acute and chronic embolism. Symptoms cover the entire spectrum from asymptomatic patients to sudden death. In addition to obstruction of the pulmonary vasculature there may be an inflammatory cascade that deteriorates vascular, pulmonary and cardiac function. In most cases the patient history and radiological imaging reveals the true nature of the patient's condition. The purpose of this article is to give the reader a survey on pathophysiology, typical clinical and radiological findings in different forms of nonthrombotic pulmonary embolism. The spectrum of forms presented here includes pulmonary embolism with biological materials (amniotic fluid, trophoblast material, endogenous tissue like bone and brain, fat, Echinococcus granulosus, septic emboli and tumor cells); nonbiological materials (cement, gas, iodinated oil, glue, metallic mercury, radiotracer, silicone, talc, cotton, and hyaluronic acid); and foreign bodies (lost intravascular objects, bullets, catheter fragments, intraoperative material, radioactive seeds, and ventriculoperitoneal shunts).

    Facial injuries with the retention of foreign bodies inside the tissues, both in soft and hard ones, can cause major functional and aesthetic damage. Among the different etiological agents, cutting tools, fragments of a firearm, the splinter of wood, steel, or iron, launched by misuse, or even caused by defects in equipment, are the main cause of these injuries. The aim of this study was to discuss the peculiarity of the multidisciplinary approach in caring of a 33-year-old man, victim of an accident at work, by the rupture of an emery disc and consequent penetration of the fragments in violation of the tissues in the orbital and zygomatic region of the left side, with perforation of the eyeball and orbital-zygomatic fracture. Urgent treatment consisted of debridement of wounds, bleeding control, removal of foreign bodies, fracture reduction with rigid internal fixation, and suture, performed by the oral and maxillofacial surgical team. Reconstruction of orbital tissues by the ophthalmology team consisted of suture of the injuries. About 1 month after the trauma, phthisis bulbi was noted, and the patient underwent a new procedure under general anesthesia for eye evisceration and installation of an alloplastic prosthesis associated with the homogenous sclera. Facial harmony was restored, especially in aesthetics and function of the zygomatic-orbital complex. PMID:21772171

    The number of implanted medical devices is steadily increasing and has become an effective intervention improving life quality, but still carries the risk of infection. These infections are mainly caused by biofilm-forming staphylococci that are difficult to treat due to the decreased susceptibility to both antibiotics and host defense mechanisms. To understand the particular pathogenesis and treatment tolerance of implant-associated infection (IAI) animal models that closely resemble human disease are needed. Applications of the tissue cage and catheter abscess foreign body infection models in the mouse will be discussed herein. Both models allow the investigation of biofilm and virulence of various bacterial species and a comprehensive insight into the host response at the same time. They have also been proven to serve as very suitable tools to study the anti-adhesive and anti-infective efficacy of different biomaterial coatings. The tissue cage model can additionally be used to determine pharmacokinetics, efficacy and cytotoxicity of antimicrobial compounds as the tissue cage fluid can be aspirated repeatedly without the need to sacrifice the animal. Moreover, with the advance in innovative imaging systems in rodents, these models may offer new diagnostic measures of infection. In summary, animal foreign body infection models are important tools in the development of new antimicrobials against IAI and can help to elucidate the complex interactions between bacteria, the host immune system, and prosthetic materials.

    The aim of this study is to report our experience in the diagnosis and treatment of tracheobronchial foreign bodies (TFBs). We retrospectively reviewed medical records of 2,000 TFB patients (1,260 males and 740 females) who were treated between January 2010 and December 2013. Chest radiography and computed tomography were performed to diagnose TFBs. The location and type of foreign bodies (FBs), anesthesia methods, and treatment outcomes and complications were analyzed. Overall, 72.5% of our patients with TFB were aged between 1 years and 3 years. Plant-based FBs are the most common FB type, accounting for 91.5%. Almost 52.1% of the FBs were encountered in the right bronchus. The coincidence rate for computed tomography-based three-dimensional reconstruction was significantly greater than that for chest X-ray examination (98.7% vs 82.0%, P<0.01). Under general anesthesia, the FBs were removed by rigid bronchoscopy. Neither anesthesia complication nor intraoperative hypoxemia occurred. There were seven deaths from acute obstructive asphyxia and eight from residual FB-induced chronic asphyxia and respiration-circulation failure. In conclusion, early diagnosis and prompt treatment of TFBs with rigid bronchoscopy under general anesthesia is effective in reducing complications and mortality in affected children. PMID:26357477

    Bone substitute materials of different origin and chemical compositions are frequently used in augmentation procedures to enlarge the local bone amount. However, relatively little data exist on the long-term tissue reactions. The presented case reports for the first time histological and histomorphometrical analyses of a nanocrystaline hydroxyapatite-based bone substitute material implanted in the human sinus cavity after an integration period of 3 years. The extracted biopsy was analyzed histologically and histomorphometrically with focus on the tissue reactions, vascularization, new bone formation, and the induction of a foreign body reaction. A comparably high rate of connective tissue (48.25%) surrounding the remaining bone substitute granules (42.13%) was observed. Accordingly, the amount of bone tissue (9.62%) built the smallest fraction within the biopsy. Further, tartrate-resistant acid phosphatase-positive and -negative multinucleated giant cells (4.35 and 3.93 cells/mm(2), respectively) were detected on the material-tissue interfaces. The implantation bed showed a mild vascularization of 10.03 vessels/mm(2) and 0.78%. The present case report shows that after 3 years, a comparable small amount of bone tissue was observable. Thus, the foreign body response to the bone substitute seems to be folded without further degradation or regeneration. PMID:26824327

    We present a case report of a 73-year-old, postmenopausal woman with detailed history of breast cancer and oncology treatment including tamoxifen therapy. She presented at the clinic of gynecology and obstetrics with recurrent inflammation of the urinary and genital tract and suspicion of a cervical mass. She also presented occasional abdominal complaints and malodorous vaginal discharge. These symptoms were observed in the patient for several years. Before hospitalization she received many kinds of empirical, antimicrobial treatment such as chlorquinaldol, metronidazole, nifuratel, and nystatin. She did not receive further guidance from doctors about the causes of ailments and further diagnostic and treatment capabilities. In our clinic a detailed diagnostic process including ultrasound transvaginal examination and a minisurgical procedure revealed the presence of a vaginal foreign body (which turned out to be a plastic, shampoo bottle cap) surrounded by a mass of inflamed tissue mimicking a cervical tumor. All symptoms and complaints subsided after surgical removal of the foreign body and antibacterial therapy with metronidazole and cefuroxime. Our study draws attention to the need of thorough gynecological care including prophylaxis, especially in the case of complaints of an intimate nature. Even trivial, frequently occurring disorders can be dangerous and require proper and responsible doctor's supervision and management through the healing process. PMID:26528112

    Two cases: A 66-year-old woman was referred to the hospital due to dyspnoea and cough. Seven months prior to referral, the patient had choked on a chunk of nut and grain-filled bread. She had daily cough and dyspnoea. The patient was convinced of an airway foreign body and she contacted her general practitioner and the emergency service several times; they all found this unlikely. Fibre optic bronchoscopy revealed two obstructing nut-like foreign bodies in the right upper and lower lobe, respectively. A 77-year-old man with sarcoidosis developed increased dyspnoea and sputum production. Three weeks earlier, the patient had choked on a magnesium tablet. Everyone was convinced that the tablet had dissolved. Infection was suspected. Chest CT scan was performed showing no obvious signs of infection or progression in sarcoidosis. After the CT scan, the patient coughed up the remains of the tablet and his symptoms resolved. Retrospective evaluation of the CT scan revealed the tablet. PMID:26002666

    Vaginal discharge in children may result from a variety of causes. A long-standing intra-vaginal foreign body can pose both diagnostic and therapeutic challenges in children. Treatment failure may occur because of alteration of the normal vaginal flora. A 6-year-old girl, who lived with her parents, presented with a foul-smelling, blood-stained vaginal discharge as well as dysuria for 2 years. There was no history of sexual abuse. Initial evaluation that excluded gynecologic examination revealed lower abdominal tenderness. Vaginal swab and urine cultures yielded Staphylococcus aureus sensitive to ceftriaxone only. She was commenced on this antibiotic for 2 weeks, but the discharge persisted, necessitating referral to the gynecologist. Examination under anesthesia by the gynecologist revealed shreds of toilet tissue paper extracted from the vagina and slight excoriations on the wall of the vagina. Vaginal foreign body can present with diverse symptoms. It should be considered in any young female patient presenting with recurrent or persistent vaginal discharge. PMID:23634340

    INTRODUCTION Foreign body ingestion rarely causes complications, though it can pose a significant diagnostic challenge. Perforation, particularly of more muscular viscera, can present insidiously with a wide range of differential diagnoses. PRESENTATION OF CASE Here we present a case of 75 year-old woman presenting with chest and epigastric pain. Initial imaging suggested a pancreatic lesion. Despite appropriate treatment she deteriorated clinically, and following urgent laparotomy a duck bone fragment was found to have perforated the lesser curvature of the stomach and embedded within the liver causing subhepatic abscess formation and associated inflammation. DISCUSSION There are a number of examples of insidious presentations of gastrointestinal perforation. However, we have found only one other case of a perforation presenting as a pancreatic pseudotumour, and ours is the first to have been successfully managed by removal of the foreign body and drainage of the abscess alone. CONCLUSION A high level of suspicion is required to make the correct diagnosis in cases such as these where the symptoms are not clear-cut. Thorough review and discussion of imaging prior to surgical treatment is essential to prevent unnecessary intervention. PMID:24926924

    Foreign body aspiration (FBA) is uncommon in the adult population but can be a life-threatening condition. Clinical manifestations vary according to the degree of airway obstruction, and, in some cases, making the correct diagnosis requires a high level of clinical suspicion combined with a detailed history and exam. Sudden cardiac arrest after FBA may occur secondary to asphyxiation. We present a 48-year-old male with no history of cardiac disease brought to the emergency department after an out-of-hospital cardiac arrest (OHCA). The patient was resuscitated after 15 minutes of cardiac arrest. He was initially managed with therapeutic hypothermia (TH). Subsequent history suggested FBA as a possible etiology of the cardiac arrest, and fiberoptic bronchoscopy demonstrated a piece of meat and bone lodged in the left main stem bronchus. The foreign body was removed with the bronchoscope and the patient clinically improved with full neurological recovery. Therapeutic hypothermia following cardiac arrest due to asphyxia has been reported to have high mortality and poor neurological outcomes. This case highlights the importance of early identification of FBA causing cardiac arrest, and we report a positive neurological outcome for postresuscitation therapeutic hypothermia following cardiac arrest due to asphyxia.

    Implantation of biomaterials into the body, e.g. for tissue engineering purposes, induces a material-dependent inflammatory response called the foreign body reaction (FBR). A hallmark feature of this response is the formation of large multinucleated cells: foreign body giant cells (FBGCs). Biomaterials like cross-linked and non-cross-linked collagen often induce the formation of FBGCs. It is unknown whether different biomaterials result in the formation of different FBGCs. To investigate this, we implanted cross-linked and non-cross-linked dermal sheep collagen subcutaneously in mice. After 21 days the implanted material was collected and prepared for ultrastructural analysis. More FBGCs formed on and between implants of cross-linked collagen compared to non-cross-linked material. The ultrastructural aspects of the FBGCs present on the two types of implants proved to be similar. On both materials, they formed long slender protrusions on the basolateral membrane, they were very rich in mitochondria, contained numerous nuclei, and showed signs of the presence of a clear zone facing the implanted material. Similar clear zones, that resemble osteoclastic features, were also seen in FBGCs generated in vitro on bone slices, but these cells did not form a ruffled border. However, similarities in ultrastructure such as the occurrence of slender protrusions and high mitochondrion content were also found in the FBGCs generated in vitro. These data indicate that FBGCs formed on different substrates share many morphological characteristics. The formation of long finger-like protrusions seemed typical for the FBGCs, in vivo as well as in vitro, however the function of these structures needs further analysis. PMID:27155321

    Application of implantable glucose biosensors for "real-time" monitoring is reliant on controlling the negative tissue reaction at the sensor tissue interphase. A novel polymer coating consisting of poly(lactic-co-glycolic) acid (PLGA) microsphere dispersed in poly(vinyl alcohol) (PVA) hydrogels was evaluated in combination with dummy sensors as a "smart" drug eluting biocompatible coating for implantable biosensors to prevent the foreign body response, and thus enhance sensor performance in vivo. The polymeric microspheres slowly release tissue-modifying drugs at the implantation sites to control the inflammation and fibrous encapsulation, while the hydrogel allows rapid analyte diffusion to the sensing elements. Dummy sensors with identical dimensions to that of the functional glucose sensors (0.5×0.5×5mm) were coated with the PLGA/PVA composites using a mold fabrication process. Both normal and diabetic rats were used in the current study to investigate the effect of the diabetic state on tissue sensor interactions. It was evident that the PLGA/PVA hydrogel composite was able to form a uniform coating around the dummy sensor and stayed intact throughout the course of the study (one month). Tissue samples containing dummy sensors that were coated with dexamethasone free composites exhibited acute and chronic inflammation as well as fibrous encapsulation in both normal and diabetic rats. However, the diabetic rats exhibited decreased intensity and delayed onset of the foreign body response following implantation of drug free dummy sensors in comparison to those of normal rats. On the other hand, tissues containing dummy sensors that were coated with dexamethasone containing composites remained normal (i.e. similar to untreated tissues), with no inflammatory reaction or fibrous encapsulation occurring over the one-month period in both the normal and diabetic rats.

    Electrospun materials have been widely explored for biomedical applications because of their advantageous characteristics, i.e., tridimensional nanofibrous structure with high surface-to-volume ratio, high porosity, and pore interconnectivity. Furthermore, considering the similarities between the nanofiber networks and the extracellular matrix (ECM), as well as the accepted role of changes in ECM for hernia repair, electrospun polymer fiber assemblies have emerged as potential materials for incisional hernia repair. In this work, we describe the application of electrospun non-absorbable mats based on poly(ethylene terephthalate) (PET) in the repair of abdominal defects, comparing the performance of these meshes with that of a commercial polypropylene mesh and a multifilament PET mesh. PET and PET/chitosan electrospun meshes revealed good performance during incisional hernia surgery, post-operative period, and no evidence of intestinal adhesion was found. The electrospun meshes were flexible with high suture retention, showing tensile strengths of 3 MPa and breaking strains of 8–33%. Nevertheless, a significant foreign body reaction (FBR) was observed in animals treated with the nanofibrous materials. Animals implanted with PET and PET/chitosan electrospun meshes (fiber diameter of 0.71±0.28 µm and 3.01±0.72 µm, respectively) showed, respectively, foreign body granuloma formation, averaging 4.2-fold and 7.4-fold greater than the control commercial mesh group (Marlex). Many foreign body giant cells (FBGC) involving nanofiber pieces were also found in the PET and PET/chitosan groups (11.9 and 19.3 times more FBGC than control, respectively). In contrast, no important FBR was observed for PET microfibers (fiber diameter = 18.9±0.21 µm). Therefore, we suggest that the reduced dimension and the high surface-to-volume ratio of the electrospun fibers caused the FBR reaction, pointing out the need for further studies to elucidate the mechanisms underlying

    Background & Aims Gastric injections of botulinum toxin A (BTA) have been reported to delay gastric emptying, increase satiation, and reduce body weight, but there are few data from randomized, placebo-controlled studies. Methods We enrolled 60 obese participants in a 24-week, double-blind, randomized, placebo-controlled, concealed allocation trial to compare the effects of gastric antral injections of BTA (100 U, 300 U, or 500 U) and saline placebo. The study was conducted at an outpatient clinical research unit. Participants were given one set of injections of BTA or placebo into the gastric antral muscularis propria, using endoscopic ultrasound guidance. Gastric emptying of solids (GES) was measured by scintigraphy; we also measured body weight, satiation (maximum tolerated volume in a caloric liquid drink test), calorie intake (by food frequency questionnaire), gastrointestinal symptoms, and psychologic aspects of eating behavior (by rating scale). Results Compared with baseline values, 2 weeks after injections, the mean t1/2 for GES increased by 0.8, 14, 24, and 14 minutes among subjects given placebo, 100 U, 300 U, or 500 U of BTA, respectively (P=.24 overall, P=.04 for the group given 300 U vs placebo); 16 weeks after the injections, mean body weights were reduced by 2.2, 0.2, 2.3, and 3.0 kg in these groups, respectively. There were no statistically significant differences in mean body weight change, satiation volume, caloric intake, gastrointestinal symptoms, or psychological aspects of eating behavior among groups. Conclusions Gastric antral injections of BTA may delay gastric emptying at a dose of 300 U, but do not cause early satiety, altered eating behaviors, or loss of body weight.

    Using ultrasound for detecting soft tissue foreign bodies seems to be the preferred choice with minimum invasion and easy availability at the bedside in emergency departments. In this study, a workshop (1 hour of lecture presentation and 3 hours of interactive hands-on) was designed to evaluate the efficacy of a short course of simple interactive training to improve the ability of emergency medicine residents to detect foreign bodies with ultrasound. Eight pieces of fresh full thickness (10 × 10 × 10 cm) lamb leg muscle were used in this study. Five different types of foreign bodies, including: a piece of glass (5 × 5 × 4 mm), wood (5 × 5 × 4 mm), gravel (5 mm diameter), plastic (5 × 5 × 2 mm) and a nail (25 mm in length) were placed deep inside each lamb leg. An ultrasound machine with a 7.5 MHz linear probe was used in this study. 35 emergency medicine residents (12 PGY1, 11 PGY2 and 12 PGY3) were enrolled in this study. Pretest and post-test results were compared and analyzed. Among all 35 participants in the training session, foreign body detection was significantly improved after the workshop (p < 0.001). Overall sensitivity and specificity for differentiating the presence and absence of a foreign body with 95% confidence were 60% (75% for PGY3) and 85.7% (91.7% for PGY3), respectively. The overall accuracy increased from 20.2% to 72.8% due to this session. This study supported the possibility of using ultrasound to detect foreign bodies by emergency physicians with a very short training course. This is highly beneficial for overcrowded emergency departments.

    Objectives: To study retrospectively the frequency, demographic, phenomenological, and psychiatric profile in patients presented with self-insertion of foreign bodies in the lower genitourinary tract in our institute. Materials and Methods: From January 2009 to 2015, the records of patients admitted with self-insertion of foreign bodies into the lower urinary tract were analyzed retrospectively regarding demographic and phenomenological profile, the mode of presentation, diagnosis, management, complications, and possible contributing factors leading to the event. Results: Out of 17,978 inpatients, ten patients (0.055%) presented with foreign body insertion in the lower genitourinary tract in last 6 years. Mean age was 28.1 ± 13.9 (7–50) years. Objects used for insertion were varied from seeds, twigs to the electric wire. The contributing factors were lack of partner, misconception about masturbation, and underlying psychiatric illness. The presenting symptoms were pain and swelling of the penis, difficulty in voiding, and skin ulceration. The diagnosis was possible by simple observation in four patients, X-ray kidney, ureter, and bladder, and sonography of the pelvis in six patients. Five patients had endoscopic retrieval of foreign body, 2 had an open, suprapubic cystotomy, urethrotomy was needed in one patient, and forceps removal in two patients. There were no postoperative complications. Psychiatric profile was evaluated in nine patients. Conclusions: Foreign body insertion to lower urinary tract was rare. A main cause for insertion of foreign bodies was autoerotism, misconceptions regarding masturbation, and underlying psychiatric illness. In addition to suitable method of surgical removal, counseling and psychiatric evaluation are necessary to prevent recurrences or for early detection of psychiatric problems. PMID:27453657

    An 8-year-old, female domestic shorthair cat was presented with a ventral abdominal subcutaneous mass. A radiograph showed that the center of the mass contained what appeared to be steel sutures, presumed to be from an ovariohysterectomy performed 7 years earlier. The excised mass was irregular and contained numerous pockets filled with friable necrotic material and hemorrhages that were dissected by fibrous connective tissue bands. Multiple tangled and fragmented pieces of steel staples were deeply embedded within the mass. Histologically, the mass was non-encapsulated, densely cellular, and infiltrative. Neoplastic cells lined caverns and channels and were factor VIII-positive by immunohistochemistry. The neoplastic cells were oval to round with granular cytoplasm and vesicular nucleus and exhibited moderate cellular and nuclear pleomorphism. A diagnosis of subcutaneous hemangiosarcoma was made. To our knowledge, this is the first report of foreign body associated hemangiosarcoma and the first case of steel staple associated neoplasm in domestic animals. PMID:24082166

    Foreign body (FB) impaction in the oesophagus is fairly common in paediatric Gastroenterology practice. This study aims to describe a case of an unusually impacted button lithium battery, in the mid-oesophagus of a 7-year-old child that was confirmed, and removed during oesophagogastroduodenoscopy. A 7-year-old male child, presented at the Emergency Paediatric Unit of our hospital with a history of ingestion of a button-like metallic object. A plain soft tissue X-ray of the neck and chest, however, revealed a dense round object located at the sternal angle of Louis. The object was dislodged and identified as a flat lithium battery after an oesophagogastroduodenoscopy, carried out under general anaesthesia using a flexible forward-viewing video gastroscope. The button battery was subsequently passed in faeces. Endoscopic removal of impacted oesophageal FBs under general anaesthesia is an effective and safe procedure in children in experienced hands.

    A pregnant 7-y-old Beagle crossbred dog (Canis familiaris) presented with clinical signs of lethargy, dehydration, and occasional vomiting. The dog was managed with fluids, antibiotics, and supportive care for several days in an effort to maintain the pregnancy. The bitch aborted the pups at approximately 50 d of gestation and was euthanized due to her poor reproductive performance and age. Necropsy revealed a compact mass of plastic pieces in the pylorus of the stomach. The gastric foreign body was discovered to be the vinyl covering of a bed that was in the dog's run as part of the environmental enrichment program for this animal. The use of that type of dog bed was discontinued. This case emphasizes that any type of enrichment can cause harm and the risks must be assessed carefully before implementing any enrichment device.

On closer questioning, he was admitted to ‘inhaling something’ that may have been caught in the mouthpiece of his inhaler and wondered whether there might be something in his chest. On examination, he had a monophonic high-pitched wheeze in his right mid-zone; chest X-ray confirmed the presence of a foreign body in his right main bronchus. As it was after normal working hours, he was referred for bronchoscopy under the cardiothoracic surgeons at St George's.

    Introduction Penile strangulation from constricting metallic objects disorders is an uncommon urological emergency which requires prompt intervention to prevent complications. The treatment modalities are diverse and characterized by lack of consensus. Material and Methods Three cases with penile incarceration due to constricting metallic objects who presented to our department were included in this study. All 3 patients required different management options highlighting the diversity of clinical presentation and need for customization of treatment as per the clinical scenario. Results The 3 patients required different approach for treatment. First patient could be managed by degloving of penile skin while second patient required mechanical removal of the foreign body and debridement of local necrotic tissues. The third patient had to undergo excision of gangrenous penile skin and skin grafting. Conclusion The study emphasizes the diversity of clinical presentations and the need for employing different surgical techniques to achieve the desired results. PMID:24917757

    In this case report, we describe our experience of a self-inflicted long complex urethrovesical foreign body managed suprapubically through the minimally invasive technique. A 21-year-old man with antipsychotic treatment for the past 10 years presented with a long electric cable wire in his bladder with the distal end in the penile urethra. He presented with symptoms of voiding difficulty and gross haematuria. An attempt of gentle retrieval of wire through the cystoscopic forceps was not successful due to a very complex knot of cable in the bladder. To avoid open surgery such as suprapubic cystotomy, the percutaneous minimally invasive approach was planned. Access to the bladder was achieved by the suprapubic puncture of the bladder, placement of a guide-wire and serial dilation of supra-pubic tract. With the help of nephroscope, through suprapubic tract, the cable wire was retrieved antegradely without causing undue trauma to the bladder or urethra. PMID:23749820

    Foreign body (FB) inhalation in the tracheobronchial tree is an infrequently encountered event in adults. The diagnosis is suspected in the presence of a clinical history of aspiration and the presence of respiratory symptoms. Management involves confirmation by flexible bronchoscopy, which may be both diagnostic as well as therapeutic. However, in certain situations including those with large FB, FB embedded in granulation tissue or FB with very smooth margins, rigid bronchoscopy may be superior to flexible bronchoscopy in the retrieval of the FB. An alternative to rigid bronchoscopy in such situations may be the use of a cryoprobe. Herein, we describe a patient with a large tracheobronchial FB causing a complete collapse of the left lung and hypoxemia. The FB was successfully extracted using a cryoprobe during flexible bronchoscopy, obviating the need for rigid bronchoscopy. PMID:27625452

    A case of meningioma is reported. At the age of 18 years, the patient had undergone insertion of a Torkildsen shunt through a posteroparietal burr hole for obstructive hydrocephalus secondary to a tumor of the pineal region, of which no biopsy had been made. After the hydrocephalus was relieved, he underwent irradiation of the tumor. Thirty years later, he was treated for an intracranial meningioma wrapped around the shunt. The tumor followed the shunt in all of its intracranial course. Microscopy disclosed pieces of the shunt tube within the meningioma. The role of a foreign body and irradiation in the induction of meningiomas is discussed, and a comprehensive review of the literature is presented. 47 references.

    Although the release of nitric oxide (NO) from biomaterials has been shown to reduce the foreign body response (FBR), the optimal NO release kinetics and doses remain unknown. Herein, polyurethane-coated wire substrates with varying NO release properties were implanted into porcine subcutaneous tissue for 3, 7, 21 and 42 d. Histological analysis revealed that materials with short NO release durations (i.e., 24 h) were insufficient to reduce the collagen capsule thickness at 3 and 6 weeks, whereas implants with longer release durations (i.e., 3 and 14 d) and greater NO payloads significantly reduced the collagen encapsulation at both 3 and 6 weeks. The acute inflammatory response was mitigated most notably by systems with the longest duration and greatest dose of NO release, supporting the notion that these properties are most critical in circumventing the FBR for subcutaneous biomedical applications (e.g., glucose sensors).

    Foreign body (FB) ingestion is a relatively common reason for visits to the emergency room. If the FB is symptomatic or damaging to the patient, either endoscopic or surgical intervention should ensue. We present a case of abdominal pain and hematuria beginning ∼24 h after an incidental FB ingestion. Initial CT imaging defined a linear opacity perforating through the posterior duodenal wall abutting the ureter causing inflammation and hydronephrosis. After two unsuccessful endoscopic attempts at retrieval, we were able to identify the object with the aid of intraoperative fluoroscopy and surgically remove the FB. The patient recovered uneventfully and was discharged home. Posterior duodenal perforation by an FB may not manifest with obvious localized or systemic symptoms unless the perforation involves surrounding structures such as the aorta, vena cava or ureter. In such cases, surgical intervention is required for FB removal. PMID:26903557

    A tooth-like foreign body (FB) was found inside a sausage bread. Analysis aimed to investigate whether the FB was a tooth and its origin. The FB was measured, weighed, photographed, and radiographed. Macroscopic findings were suggestive of an anterior tooth. Histological slides of undecalcified cross-sections of the FB and samples of human and swine teeth were prepared. Histological features of the FB (in light microscopy, 125× magnification) were discrepant from human tissues. Compared histological analysis displayed majority of features consistent with a hypsodont swine tooth, probably a canine. Cellularized cementum in crown region, adjacent to the enamel, and shape of the cementocytes were the main criteria excluding the possibility of human origin of the FB. Scanning electronic microscopy and energy-dispersive spectroscopy were not performed because of fewer features to be analyzed and FB size. It was concluded that the FB may have been incorporated during meat grinding of the sausage. PMID:22804486

    The use of plain radiographs to localize a suspected fishbone foreign body is the subject of controversy. Accordingly radiographs of 14 species of fishbone, impacted in a soft tissue phantom, were assessed by a series of observers from the ENT department (consultant surgeons, senior registrars and house officers). The agreement was assessed by graphical description of the data and tested by a Spearman's rank correlation test. The overall results showed that, for the clinician, radiography is very useful to detect the bones of: cod, haddock, lemon sole, cole fish, grey mullet and plaice; useful for red snapper, monk fish, gurnard and salmon; and unhelpful in detecting bones from herring, pike, mackerel and trout. The use of radiographs to locate these impacted fishbones can be rationalized in the light of these findings. Images Figure 1 PMID:8709081

  8. A comparative 18F-FDG PET/CT imaging of experimental Staphylococcus aureus osteomyelitis and Staphylococcus epidermidis foreign-body-associated infection in the rabbit tibia

    PubMed Central

    2012-01-01

    Background 18F-FDG-PET imaging has emerged as a promising method in the diagnosis of chronic osteomyelitis commonly due to Staphylococcus aureus. The inaccuracy of 18 F-FDG-PET in the detection of periprosthetic joint infections may be related to the predominance of low-virulent S. epidermidis strains as the causative pathogen. We have compared the18F-FDG-PET characteristics of S. aureus osteomyelitis and foreign-body-associated S. epidermidis infections under standardized laboratory conditions. Methods Twenty-two rabbits were randomized into three groups. In group 1, a localized osteomyelitis model induced with a clinical strain of S. aureus was applied. In groups 2 and 3, a foreign-body-associated infection model induced with a clinical or laboratory strain of S. epidermidis was applied. A small block of bone cement was surgically introduced into the medullary cavity of the proximal tibia followed by peri-implant injection of S. aureus (1 × 105 CFU/mL) or one of the two S. epidermidis (1 × 109 CFU/mL) strains with an adjunct injection of aqueous sodium morrhuate. In group 1, the cement block was surgically removed at 2 weeks but left in place in groups 2 and 3 in order to mimic foreign-body-associated S. epidermidis infections. At 8 weeks, the animals were imaged using 18 F-FDG PET/CT. The presence of bacterial infection was confirmed by cultures, and the severity of bone infections was graded by means of radiography, peripheral quantitative CT, and semi-quantitative histology. Results The S. aureus strain caused constantly culture-positive osteomyelitis. The clinical S. epidermidis strain resulted in foreign-body-associated infections, while the laboratory S. epidermidis strain (ATCC 35983) induced only occasionally culture-positive infections. There was a correlation (r = 0.645; P = 0.013) between semi-quantitative score of leukocyte infiltration and the 18 F-FDG uptake in animals with positive cultures. Standardized uptake value

    We present a case of endovascular retrieval of a penetrating foreign body that was originally lodged in the mediastinum and then migrated to the hepatic vein. The steel nail entered the thorax and traversed the left lung causing a pneumothorax. The patient underwent a thoracotomy, but the foreign body had migrated from its original mediastinal position. A postsurgical CT showed that the object was below the right hemidiaphragm. Diagnostic venogram demonstrated that the object was in the main hepatic vein. Using a double-snare technique, the object was safely and successfully removed from the hepatic vein via the right common femoral vein.

    Foreign body aspiration (FBA) is more common in children than adults with about 80% occurring in children aged less than 15 years. FBA in adults is often overlooked as a potential cause of airway obstruction especially if there is no asphyxiation. We present a case of a 45-year-old male with alcohol abuse who presented with post-obstructive pneumonia secondary to aspiration of tooth of unknown duration. The tooth was removed via flexible bronchoscopy (FBr) and we will discuss the use of FBr for foreign body (FB) removal, which FB can be easily removed by FBr, and the different techniques and devices used for FB removal via FBr.

    2013-01-01

    Objective The brain foreign body response (FBR) is an important process that limits the functionality of electrodes that comprise the brain-machine interface. Associated events in this process include leakage of the blood brain barrier (BBB), reactive astrogliosis, recruitment and activation of microglia, and neuronal degeneration. Proper BBB function is also integral to maintaining neuronal health and function. Previous attempts to characterize BBB integrity have shown homogeneous leakage of macromolecules up to 10 nm in size. In the present study, we describe a new method of measuring BBB permeability during the foreign body response in a mouse model. Approach Fluorescent nanoparticles were delivered via the tail vein into implant-bearing mice. Tissue sections were then analyzed using fluorescence microscopy to observe nanoparticles in the tissue. Gold nanoparticles were also used in conjunction with TEM to confirm the presence of nanoparticles in the brain parenchyma. Main results By using polymer nanoparticle tracers, which are significantly larger than conventional macromolecular tracers, we show near-implant BBB gaps of up to 500 nm in size that persist for at least 4 weeks after implantation. Further characterization of the BBB illustrates that leakage during the brain FBR is heterogeneous with gaps between at least 10 and 500 nm. Moreover, electron microscopy was used to confirm that the nanoparticle tracers enter into the brain parenchyma near chronic brain implants. Significance Taken together, our findings demonstrate that the FBR-induced BBB leakage is characterized by larger gaps and is of longer duration than previously thought. This technique can be applied to examine the BBB in other disease states as well as during induced, transient, BBB opening. PMID:23337399

    Surgical mesh devices composed of synthetic materials are commonly used for ventral hernia repair. These materials provide robust mechanical strength and are quickly incorporated into host tissue; factors which contribute to reduced hernia recurrence rates. However, such mesh devices cause a foreign body response with the associated complications of fibrosis and patient discomfort. In contrast, surgical mesh devices composed of naturally occurring extracellular matrix (ECM) are associated with constructive tissue remodeling, but lack the mechanical strength of synthetic materials. A method for applying a porcine dermal ECM hydrogel coating to a polypropylene mesh is described herein with the associated effects upon the host tissue response and biaxial mechanical behavior. Uncoated and ECM coated heavy-weight BARD™ Mesh were compared to the light-weight ULTRAPRO™ and BARD™ Soft Mesh devices in a rat partial thickness abdominal defect overlay model. The ECM coated mesh attenuated the pro-inflammatory response compared to all other devices, with a reduced cell accumulation and fewer foreign body giant cells. The ECM coating degraded by 35 days, and was replaced with loose connective tissue compared to the dense collagenous tissue associated with the uncoated polypropylene mesh device. Biaxial mechanical characterization showed that all of the mesh devices were of similar isotropic stiffness. Upon explantation, the light-weight mesh devices were more compliant than the coated or uncoated heavy-weight devices. The present study shows that an ECM coating alters the default host response to a polypropylene mesh, but not the mechanical properties in an acute in vivo abdominal repair model. PMID:23873846

    Purpose We report a rare case of traumatic injury to the eye caused by homemade fireworks in a Chinese juvenile patient with a metal ring left in the orbit after having been sutured at the Emergency Department. Methods An 11-year-old boy presented with a traumatic injury to the right eye from homemade fireworks. Following initial assessment involving maxillofacial computed tomography (CT) and suturing at the Emergency Department, he was transferred to our department for further evaluation because of his poor sight 1 day later. On examination, a skin laceration beneath the right eyebrow was noted, but the superior orbit was not fully visible on the maxillofacial CT performed 1 day previously. Therefore, an orbital CT scan was carried out on the second day, which showed a hyperdense ring embedded in the superior border of the orbital wall; the ring was surgically removed. On postoperative day 7, a fundus examination revealed resolving vitreous hemorrhage, blunt traumatic retinal detachment, and a large retinal tear superior to the macula. The patient refused to take surgery for retinal detachment into consideration. Therefore, we opted for oral steroids and careful observation. Results After 2 months’ observation, the large retinal tear had healed and white fibrous scar tissue had developed, and the retinal detachment superior to the macula had reattached itself spontaneously. The patient's vision had further improved to 20/200. During 1 year of follow-up, he remained clinically stable. Conclusion To avoid missing the diagnosis, a complete history of the mechanism of injury and accurate imaging still prove most useful. Complete removal of the foreign body by the emergency physician is necessary because of the ocular toxicity of an iron-containing foreign body. As evidenced by the current case, oral steroids and observation for a period of several months is a management of choice for traumatic retinal detachment and retinal tear superior to the macula associated

    This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the removal of foreign bodies in the upper gastrointestinal tract in adults. Recommendations Nonendoscopic measures 1 ESGE recommends diagnostic evaluation based on the patient's history and symptoms. ESGE recommends a physical examination focused on the patient's general condition and to assess signs of any complications (strong recommendation, low quality evidence). 2 ESGE does not recommend radiological evaluation for patients with nonbony food bolus impaction without complications. We recommend plain radiography to assess the presence, location, size, configuration, and number of ingested foreign bodies if ingestion of radiopaque objects is suspected or type of object is unknown (strong recommendation, low quality evidence). 3 ESGE recommends computed tomography (CT) scan in all patients with suspected perforation or other complication that may require surgery (strong recommendation, low quality evidence). 4 ESGE does not recommend barium swallow, because of the risk of aspiration and worsening of the endoscopic visualization (strong recommendation, low quality evidence). 5 ESGE recommends clinical observation without the need for endoscopic removal for management of asymptomatic patients with ingestion of blunt and small objects (except batteries and magnets). If feasible, outpatient management is appropriate (strong recommendation, low quality evidence). 6 ESGE recommends close observation in asymptomatic individuals who have concealed packets of drugs by swallowing ("body packing"). We recommend against endoscopic retrieval. We recommend surgical referral in cases of suspected packet rupture, failure of packets to progress, or intestinal obstruction (strong recommendation, low quality evidence). Endoscopic measures 7 ESGE recommends emergent (preferably within 2 hours, but at the latest within 6 hours) therapeutic esophagogastroduodenoscopy for

    The paper contains new numerical simulation and experimental test results of blunt body drag reduction using thin spikes mounted in front of a body and one- or two-phase jets injected against a supersonic flow. Numerical simulations utilizing the NASA CFL3D code were conducted at the Hampton University Fluid Mechanics and Acoustics Laboratory (FM&AL) and experimental tests were conducted using the facilities of the IM/MSU Aeromechanics and Gas Dynamics Laboratory. Previous results were presented at the 37th AIAA/ASME/SAE/ASEE Joint Propulsion Conference. Those results were based on some experimental and numerical simulation tests for supersonic flow around spike-nosed or shell-nosed bodies, and numerical simulations were conducted only for a single spike-nosed or shell-nosed body at zero attack angle, alpha = 0 degrees. In this paper, experimental test results of gas, liquid and solid particle jet injection against a supersonic flow are presented. In addition, numerical simulation results for supersonic flow around a multiple spike-nosed body with non-zero attack angles and with a gas and solid particle forward jet injection are included. Aerodynamic coefficients: drag, C (sub D), lift, C(sub L), and longitudinal momentum, M(sub z), obtained by numerical simulation and experimental tests are compared and show good agreement.

    In this study, the effect of soft segment chemistry on the phase morphology and in vivo response of commercial-grade poly(ether urethane) (PEU), silicone-modified PEU (PEU-S), poly(carbonate urethane) (PCU), and silicone-modified PCU (PCU-S) elastomers were examined. Silicone-modified polyurethanes were developed to combine the biostability of silicone with the mechanical properties of PEUs. Results from the infrared spectroscopy confirmed the presence of silicone at the surface of the PEU-S and PCU-S films. Atomic force microscopy phase imaging indicated that the overall two-phase morphology of PEUs, necessary for its thermoplastic elastomeric properties, was not disrupted by the silicone modification. After material characterization, the in vivo foreign body response and biostability of the polyurethanes were studied using a subcutaneous cage implant protocol. The results from the cage implant study indicated that monocytes adhere, differentiate to macrophages which fuse to form foreign body giant cells on all of the polyurethanes. However, the silicone-modified surfaces promoted apoptosis of adherent macrophages at 4 days and high levels of macrophage fusion after 21 days. These results confirm that the surface of a biomaterial may influence the induction of apoptosis of adherent macrophages in vivo and are consistent with previous cell culture studies of these materials. This study validates the use of our standard cell culture protocol to predict in vivo behavior and further supports the hypothesis that interleukin-4 is the primary mediator of macrophage fusion and foreign body giant cell formation in vivo. The impact of these findings on the biostability of polyurethanes is the subject of current investigations. Attenuated total reflectance-Fourier transform infrared analysis of explanted specimens provided evidence of chain scission and crosslinking at the surface of all of the polyurethanes. The silicone modification did not fully inhibit the oxidative

    Osteoclasts are multinucleated cells responsible for bone resorption. They are derived from the fusion of cells in the monocyte/macrophage lineage. Monocytes and macrophages can also fuse to form foreign body giant cells (FBGC). Foreign body giant cells are observed at the interface between a host and a foreign body such as implants during a foreign body reaction. Macrophages are attracted to the site of bone resorption and foreign body reactions by different cytokines. Chemokine (C-C) ligand-2 (CCL2) is an important chemotactic factor and binds to a receptor CCR2. In this study we investigated the importance of CCL2 and the receptor CCR2 in the formation of osteoclasts and FBGC. CCL2 mRNA was more highly expressed in giant cell culture than macrophages, being 9-fold and 16-fold more abundant in osteoclasts and FBGC respectively. Significantly fewer osteoclasts and FBGC were cultured from the bone marrow of CCL2 and CCR2 knockout mice, when compared to wild type. Not only were the number of giant cells reduced but there was a significant reduction in the number of nuclei and the size of these cells in the cultures of CCL2 and CCR2 knockout mice. Formation of osteoclasts and FBGC were recovered in cultures by addition of exogenous CCL2 to the media containing marrow cells from CCL2-/- mice. We conclude that CCL2 and its receptor CCR2 are important for the formation of osteoclasts and FBGC and absence of these genes causes inhibition of osteoclast and FBGC formation. PMID:26205994

    It is not so common to aspirate foreign body in normal adults without any predisposing factors as compared to children and those with the altered neurological state. Endobronchial foreign bodies are one of the causes of obstructive pneumonia and difficult to diagnose as signs and symptoms are often nonspecific. However, once they are diagnosed, they can generally be removed, leading to rapid and drastic resolution of symptoms. Bronchoscopy is the gold standard in the identification and localization of an airway foreign body and also for better management of the ailment. However with the help of virtual bronchoscopy one can decide the location of the foreign body before any invasive intervention and being noninvasive it can be performed in follow-up easily to check the patency of airways. It is not possible to detect the exact size of foreign body with the virtual bronchoscopy. In this article, we report a case of unnoticed foreign body aspiration in a 49-year-old female patient who was initially treated for pneumonia. However, due to nonresolution of opacity contrast enhanced computed tomography thorax with virtual and flexible bronchoscopy were performed, which revealed a foreign body in the right lower lobe bronchus that was removed with biopsy forceps in piecemeal. In her follow-up visit, she underwent virtual broncoscopy that revealed clear airways. Thus, detailed history and high index of suspicion is required for nonresolving pneumonias that may occur due to unnoticed foreign body/ies in an adult.

    Objective We described the technique of ultrasound (US)-guided percutaneous removal of the foreign bodies (FB) with hydro-dissection in the radiologic department and presented video files of several cases. Materials and Methods Four patients referred to the radiology department for US evaluation and US-guided percutaneous removal of the FBs in the upper and lower extremities between November, 2006 and November, 2013 were included in this study. The procedures started with US evaluation for the exact location and shape of the FB. A 5 mm-sized skin incision was made at the site of the nearest point from the FB where no passing arteries or tendons were present. We adopted a hydrodissection technique to separate the FB from adjacent tissue using a 2% lidocaine solution. Injected anesthetics detached the FBs from surrounding tissue and thereby facilitated removal. After the tip of the mosquito forceps reached the FB, the wooden FBs were removed. Results The mean time required for the entire procedure was approximately 20 minutes. There were no significant complications during the US-guided removal or long-term complications after the procedure. All 4 FBs were successfully removed from the soft tissue under US guidance. Conclusion Ultrasound-guided percutaneous removal of the FBs with hydro-dissection in the radiology department is a less invasive and safe method over surgical removal in the operating room. Additionally, the use of a guide wire and serial dilator may help minimize soft tissue injury and facilitate the introduction of forceps. PMID:26576123

    Aim: To evaluate visual outcome following pars plana vitrectomy (PPV) and intraocular foreign body (IOFB) removal through the sclerocorneal tunnel combined with simultaneous cataract extraction and sulcus-fixated intraocular lens (IOL) implantation as a single procedure in penetrating ocular trauma with IOFB and traumatic cataract. Materials and Methods: Eighteen cases of penetrating ocular trauma with retained IOFB and traumatic cataract who underwent PPV, IOFB body removal and cataract extraction with posterior chamber IOL (PCIOL) implantation in the same sitting, between June '04 and December '05 were retrospectively analyzed. All the foreign bodies were removed through the sclerocorneal tunnel. Result: All the 18 patients were young males, with an average follow-up period of 12 months. In 12 cases the foreign body was intravitreal and in six cases it was intraretinal but extramacular. Thirteen cases had a best corrected visual acuity ranging from 20/20 to 20/60 at their last follow-up. Five cases developed retinal detachment due to proliferative vitreoretinopathy (PVR) changes postoperatively and were subsequently managed by surgery. Conclusion: Primary IOL implantation with combined cataract and vitreo-retinal surgery is a safe option reducing the need for two separate surgeries in selected patients with retained IOFB and traumatic cataract. This combined procedure provides good visual outcome with early rehabilitation in young working patients. PMID:20195033

    Mast cell activation has been shown to be an initiator and a key determinant of foreign body reactions. However, there is no non-invasive method that can quantify the degree of implant-associated mast cell activation. Taking advantage of the fact that fibrin deposition is a hallmark of mast cell activation around biomaterial implants, a near infrared probe was fabricated to have high affinity to fibrin. Subsequent in vitro testing confirmed that this probe has high affinity to fibrin. Using a subcutaneous particle implantation model, we found significant accumulation of fibrin-affinity probes at the implant sites as early as 15 min following particle implantation. The accumulation of fibrin-affinity probes at the implantation sites could also be substantially reduced if anti-coagulant – heparin was administered at the implant sites. Further studies have shown that subcutaneous administration of mast cell activator – compound 48/80 – prompted the accumulation of fibrin-affinity probes. However, implant-associated fibrin-affinity probe accumulation was substantially reduced in mice with mast cell deficiency. The results show that our fibrin-affinity probes may serve as a powerful tool to monitor and measure the extent of biomaterial-mediated fibrin deposition and mast cell activation in vivo.

    Sugammadex is a selective chemical agent that can reverse neuromuscular blockade induced by vecuronium and rocuronium. The aim of this report is to discuss the effectiveness of sugammadex in the reversal of neuromuscular blockade in children younger than 2 years. A 16-month-old boy, weighing 10 kg, was admitted to the pediatric emergency department due to choking, cyanosis, and severe respiratory distress that occurred while he was eating peanuts. In the emergency department, the patient's condition deteriorated, and he went into respiratory arrest. He was immediately intubated and taken to the operating room. A rigid bronchoscopy was performed under general anesthesia, with administration of intravenous pentothal (5 mg/kg), rocuronium (0.6 mg/kg), and fentanyl (0.5 μg/kg) in the operating room. The foreign body was removed within 6 minutes, and the profound neuromuscular blockade was reversed with a dose of 2 mg/kg sugammadex. He was extubated successfully after obtaining the spontaneous respiratory activity, and adequate breathing was restored. Clinical use of sugammadex in children younger than 2 years is not recommended because of the lack of clinical studies. In this case report, the profound neuromuscular blockade was successfully reversed with a dose of 2 mg/kg sugammadex in a 16-month-old boy. However, more prospective clinical studies are required for the safe use of this agent in children. PMID:27555184

    Sodium polystyrene sulfonate (SPS) (Kayexalate) is a cation-exchange resin used to treat hyperkaliema. Administered with sorbitol, it usually has minor adverse effects, but it may cause colonic or intestinal necrosis in uremic patients. We report an unusual case of rectal stenosis due to SPS crystals in a 46-year-old man. The patient had been involved in a car accident with severe thoracic and abdominal trauma. During his hospitalization, he presented traumatic acute pancreatitis with ischemic colitis because of hypotension, and acute renal insufficiency treated by hemofiltration and Kayexalate administered by nasogastric tube without sorbitol. Left colon was resected and Hartmann's procedure was performed. Restoration of the colon continuity was performed 13 months later. The rectal lumen was narrowed with a thickened rectal wall. Microscopic examination revealed fibrosis of the submucosa containing numerous basophilic polygonal crystals surrounded by macrophages. This is the first case report of rectal stenosis caused by foreign body reaction to SPS crystals after ischemic colitis. PMID:17498597

    Among the myriad emergencies that could arise in the dental clinical setting there are a few that occur occasionally despite being entirely preventable. Ingestion or aspiration of dental materials, appliances, or instruments comprises this category. Regardless of incidence, foreign body ingestion or aspiration episodes are recognized as potential complications in the specialty of orthodontics. Despite their infrequent occurrence, the morbidity from a single incident and the amount of specialty medical care that may be needed to manage such incidents is too high to ignore. There is also the associated risk of malpractice litigation given the fact that these incidents are preventable. At present, no clear guidelines exist regarding prevention of this emergency in practice. This article attempts to review relevant literature and aims to formulate certain recommendations based on best available evidence to minimize the incidence of such events, while also suggesting guidelines toward making their management more effective. A flow chart outlining management options and strategies to aid the clinician in the event of such an emergency is also presented. PMID:22701326

    Implantation of biomaterials and devices into soft tissues leads to the development of the foreign body response (FBR), which can interfere with implant function and eventually lead to failure. The FBR consists of overlapping acute and persistent inflammatory phases coupled with collagenous encapsulation and currently there are no therapeutic options. Initiation of the FBR involves macrophage activation, proceeding to giant cell formation, fibroblast activation, and collagen matrix deposition. Despite the recognition of this sequence of events, the molecular pathways required for the FBR have not been elucidated. We have identified that the acute inflammatory response to biomaterials requires nucleotide-binding domain and leucine-rich repeat-containing 3 (Nlrp3), apoptosis-associated speck-like protein containing CARD (Asc), and caspase-1, as well as plasma membrane cholesterol, and Syk signaling. Full development of the FBR is dependent on Asc and caspase-1, but not Nlrp3. The common antiinflammatory drug aspirin can reduce inflammasome activation and significantly reduce the FBR. Taken together, these findings expand the role of the inflammasome from one of sensing damage associated molecular patterns (DAMPs) to sensing all particulate matter irrespective of size. In addition, implication of the inflammasome in biomaterial recognition identifies key pathways, which can be targeted to limit the FBR. PMID:22109549

    Infratemporal fossa cellulitis is rare and mostly occurs because of sinusitis and dental procedures. Furthermore, cellulitis caused by iatrogenic foreign bodies is very rare. A 28-year-old woman who had previously undergone cosmetic bimaxillary operation visited our hospital complaining of left facial swelling, oppressive pain, and nasal obstruction since 2 years. She had been attending another clinic, but despite having additional procedures and taking medications, her symptoms persisted. A subsequent operation was performed, during which we found a remnant surgical gauze from the previous operation, which was decomposed and trapped around the necrotic soft tissue and had eroded the bony structure around the pterygoid fossa. The material was successfully removed by endoscopic surgery, and the necrotic tissue was debrided. After the operation, all symptoms disappeared, and the patient was discharged without sequelae. During any procedure, surgeons must meticulously check for remnant material. Additionally, physicians must carefully note patient history and perform a physical examination, even in patients without serious symptoms. We report a case of advanced infratemporal fossa cellulitis due to remnant gauze material during a previous operation that was undetected. PMID:25950522

    Background: Laparoscopy is widely used as a tool in many clinical situations allowing for diagnosis and/or surgical management in a minimally invasive fashion. Most laparoscopic cases are ambulatory and allow patients to recover quickly. Nonetheless, attention to surgical technique is paramount to avoid both short and long term complications. Case: A 32-year-old woman had a laparoscopy and a reported left salpingoophorectomy for benign disease of the ovary in September, 1994. Shortly thereafter, in January, 1995, she was diagnosed with an intrauterine pregnancy and delivered in October of 1995 by spontaneous vaginal delivery. The pregnancy and delivery were both uncomplicated. The patient presented four weeks postpartum with clinical suspicion of appendicitis. However, at the time of laparotomy, the patient was found to have a retained foreign body from her prior laparoscopy in the right lower quadrant with a pelvic abscess and evidence of prior right salpingoophorectomy. The appendix appeared grossly normal. Conclusion: Laparoscopy is a safe, effective modality for various surgical and gynecologic conditions. Although laparoscopy is usually done on an outpatient basis, complications can manifest several weeks or months later. This case illustrates and reminds us of the importance of adherence to surgical laparoscopic principles. These include direct visualization when removing equipment and a complete count of surgical instrumentation to confirm the integrity of such at the end of each procedure. PMID:9876653

    We describe our experience with blowgun dart aspiration via an illustrative case series and review the resources available to teach children how to construct these objects. A 15-year-old boy presented with cough, wheeze, and eventually admitted to aspiration of a homemade blowgun dart. This instance heightened the awareness of our experience with blowgun dart aspiration as 3 cases presented within a 3-month period. Patients uniformly presented with cough and reported aspiration, and wheezing was noted in 2 of the 3. Although all ultimately admitted their behavior, 2 were initially reluctant to admit aspirating the blowgun dart. Radiographic findings of a needle-shaped metallic airway foreign body were consistent in all patients. Each admitted to finding instructions for blowgun dart construction on the Internet. Emergent rigid bronchoscopy with blowgun dart removal resulted in symptom resolution in all without complication. This represents the largest series of blowgun dart aspiration to date. During deep inhalation, when preparing to propel a blowgun dart, the vocal folds maximally abduct, leading to increased risk for aspiration. Twenty websites were identified providing instructions for the construction of homemade blowgun darts. With the accessibility of the Internet and number of instructional websites, this clinical entity may become more common in the future. Unfortunately, only a few of the websites provide any safety warnings. Certainly, prompt treatment can result in good outcomes; however, serious potential complications, including death, could occur especially given the hesitance our patients showed in divulging the truth of the inciting event.

    Implantable immunoisolation membranes need to possess superior biocompatibility to prohibit the fibrotic deposition that would reduce the nutrient supply and impair the viability/function of the encapsulated cells. Here, electrospun membranes based on thermoplastic polyurethane (TPU) were fabricated to contain microfibers (PU-micro) or nanofibers (PU-nano). The two types of membranes were compared in terms of their interaction with macrophage cells and the host tissues. It was found that the fibrous membranes of different topographies possess distinct material properties: PU-nano caused minimal macrophage responses in vitro and in vivo and induced only mild foreign body reactions compared to PU-micro membranes. A flat macroencapsulation device was fabricated using PU-nano membranes and its immunoisolation function investigated in subcutaneous transplantation models. The nanofibrous device demonstrated the capability to effectively shield the allografts from the immune attack of the host. Nanotopography may confer biocompatibility to materials and nanofibrous materials warrant further study for development of "invisible" immunoisolation devices for cell transplantation. PMID:27344368

    Background Penetrating brain injuries caused by explosions are survived in extremely rare cases only. However, potential casualties of such cases may be encountered by regular physicians even outside a war zone, e.g., due to an assault or terror blast. There is very limited literature to this end; therefore, we report the successful neurosurgical management of a penetrating head injury due to a pipe bomb explosion. Case Description A 19-year-old man was brought to the ER with a swollen, bleeding right orbit, and a severely injured left hand after having sustained an unwitnessed explosion from a self-made pipe bomb. He presented with a GCS (Glasgow Coma Scale) of 15 at time of admission, work-up revealed an intracranial retained metal fragment measuring 5 × 1 × 0.2 cm lodged retro-orbitally and in the skull base. The patient underwent emergent right temporal craniotomy and temporal lobectomy and simultaneous right enucleation before the petrous bone and sphenoid wing lodged metal fragment was successfully removed. Conclusion This case underscores the importance of having a high suspicion for the presence of an intracranial injury and a retained foreign body in the setting of a penetrating head injury. Aggressive and timely workup as well as expeditious surgical management are crucial in these settings and can generate exceptionally good outcomes despite a major trauma. PMID:21246061

    Poly(ethylene glycol) (PEG) hydrogels with their highly tunable properties are promising implantable materials, but as with all non-biological materials, they elicit a foreign body response (FBR). Recent studies, however, have shown that incorporating the oligopeptide RGD into PEG hydrogels reduces the FBR. To better understand the mechanisms involved and the role of RGD in mediating the FBR, PEG, PEG-RGD and PEG-RDG hydrogels were investigated. After a 28-day subcutaneous implantation in mice, a thinner and less dense fibrous capsule formed around PEG-RGD hydrogels, while PEG and PEG-RDG hydrogels exhibited stronger, but similar FBRs. Protein adsorption to the hydrogels, which is considered the first step in the FBR, was also characterized. In vitro experiments confirmed that serum proteins adsorbed to PEG-based hydrogels and were necessary to promote macrophage adhesion to PEG and PEG-RDG, but not PEG-RGD hydrogels. Proteins adsorbed to the hydrogels in vivo were identified using liquid chromatography-tandem mass spectrometry. The majority (245) of the total proteins (≥300) that were identified was present on all hydrogels with many proteins being associated with wounding and acute inflammation. These findings suggest that the FBR to PEG hydrogels may be mediated by the presence of inflammatory-related proteins adsorbed to the surface, but that macrophages appear to sense the underlying chemistry, which for RGD improves the FBR.

    The potential of foreign body aspiration or ingestion is a worldwide health problem in dentistry. The general dental practitioners should be extremely attentive in handling of minor instruments during any intervention related to the oral cavity, especially in the supine or semi-recumbent position of the patient. Aspiration cases are usually more critical and less common than ingestion. We report a case of iatrogenic aspiration of an endodontic broach, which gets disclosed during the recording of past dental history of the patient. The patient was asymptomatic during that time. A quick posterior-anterior chest radiograph was taken which revealed the presence of broach in the lower lobe of the left lung. The patient was immediately referred to the pulmonary medicine department where the fiberoptic bronchoscope retrieval was planned, and the same was carried out successfully under local anesthesia. Although such accidents have rare occurrence, the associated risks and morbidity are too high to be overlooked, especially from the viewpoint of special care, resources, and the associated financial cost required for their management. Moreover, practitioners are also liable for malpractice litigation given the fact that such cases are avoidable. This article also discusses relevant review literature, risk factors, symptoms, and management of such iatrogenic accidents along with drawing attention to the significance of preventive measures and their role in avoiding meritorious legal and ethical issues.

    Foreign body multinucleated giant cells (FBGCs) and osteoclasts share several characteristics, like a common myeloid precursor cell, multinuclearity, expression of tartrate-resistant acid phosphatase (TRAcP) and dendritic cell-specific transmembrane protein (DC-STAMP). However, there is an important difference: osteoclasts form and reside in the vicinity of bone, while FBGCs form only under pathological conditions or at the surface of foreign materials, like medical implants. Despite similarities, an important distinction between these cell types is that osteoclasts can resorb bone, but it is unknown whether FBGCs are capable of such an activity. To investigate this, we differentiated FBGCs and osteoclasts in vitro from their common CD14+ monocyte precursor cells, using different sets of cytokines. Both cell types were cultured on bovine bone slices and analyzed for typical osteoclast features, such as bone resorption, presence of actin rings, formation of a ruffled border, and characteristic gene expression over time. Additionally, both cell types were cultured on a biomimetic hydroxyapatite coating to discriminate between bone resorption and mineral dissolution independent of organic matrix proteolysis. Both cell types differentiated into multinucleated cells on bone, but FBGCs were larger and had a higher number of nuclei compared to osteoclasts. FBGCs were not able to resorb bone, yet they were able to dissolve the mineral fraction of bone at the surface. Remarkably, FBGCs also expressed actin rings, podosome belts and sealing zones—cytoskeletal organization that is considered to be osteoclast-specific. However, they did not form a ruffled border. At the gene expression level, FBGCs and osteoclasts expressed similar levels of mRNAs that are associated with the dissolution of mineral (e.g., anion exchange protein 2 (AE2), carbonic anhydrase 2 (CAII), chloride channel 7 (CIC7), and vacuolar-type H+-ATPase (v-ATPase)), in contrast the matrix degrading enzyme

    The efficacy of implanted biomedical devices is often compromised by host recognition and subsequent foreign body responses. Here, we demonstrate the role of the geometry of implanted materials on their biocompatibility in vivo. In rodent and non-human primate animal models, implanted spheres 1.5 mm and above in diameter across a broad spectrum of materials, including hydrogels, ceramics, metals and plastics, significantly abrogated foreign body reactions and fibrosis when compared with smaller spheres. We also show that for encapsulated rat pancreatic islet cells transplanted into streptozotocin-treated diabetic C57BL/6 mice, islets prepared in 1.5-mm alginate capsules were able to restore blood-glucose control for up to 180 days, a period more than five times longer than for transplanted grafts encapsulated within conventionally sized 0.5-mm alginate capsules. Our findings suggest that the in vivo biocompatibility of biomedical devices can be significantly improved simply by tuning their spherical dimensions.

    While foreign body aspirations are mostly seen in children, they are also observed in adulthood, but in a rare frequency. As it can be asymptomatic for a long time, it can also be confused with many clinical conditions, such as asthma, which can cause chronic cough. Various complications, such as bronchiectasis and pneumonia, can develop in the presence of long-standing aspirated foreign body. In this study, we present two cases one of whom diagnosed with asthma and treated for 30 years, and the other diagnosed with asthma and treated for 10 years. Although no pulmonary complications developed in our first case, bronchiectasis in the right middle lobe developed in our second case. PMID:26362694

    Permanent make-up is a kind of cosmetic tattoo in which the colorants (pigments) are deposited in dermis after piercing the skin by tiny solid needles. It may cause some adverse effects such as local inflammation, infection, and allergic reactions on the skin and even systemic adverse effects such as sarcoidal reactions. Here the case of a 34-year-old woman who has some yellowish hard shiny papules on her eyebrows after having a permanent make-up is described. The histopathological examinations of the papules are diagnosed as sarcoidal foreign-body reactions. All the laboratory investigations were in normal limits except a mild elevation in angiotensin converting enzyme or ACE level. The lesions mostly improved after topical corticosteroid treatment. Sarcoidal foreign-body reaction due to permanent make-up is discussed with this presentation. PMID:26073118

    The diversity of objects that can be found in the urinary bladder often surpasses the urologist's imagination and mostly they are introduced per urethrally. Impalement injuries of the rectum with bladder perforation have been rarely reported. A high index of clinical suspicion is required to make the diagnosis of bladder perforation while assessing patients presenting with rectal impalement. In this interesting case, a young male child presented with haematuria and dysuria. He had a history of accidentally sitting on an agarbatti (Indian incense stick) stand while playing, followed by perianal pain which subsided spontaneously. Next day he presented with haematuria and dysuria. Clinical examination was inconclusive. On thorough investigation, a linear echogenic foreign body was found in the urinary bladder. The child was operated and the foreign body (incense stick) was removed. This is the first reported case of rectal impalement injury with incense stick, migrated to the urinary bladder in a 2-year-old child. PMID:24925539

    Purpose Foreign body (FB) ingestion is common in children, and button battery (BB) ingestion has been increasing in recent years. This study was to identify factors related to outcomes of FB ingestion, particularly BBs in the stomach. We evaluated whether the current recommendations are appropriate and aimed to suggest indications for endoscopic removal of BB in the stomach in young children. Methods We investigated patient age, shape, size, location of FBs, spontaneous passage time and resulting complications among 76 children. We observed types, size, location of BB and outcomes, and analyzed their associations with complications. Results Coins and BB were the two most common FBs. Their shapes and sizes were not associated with the spontaneous passage time. Size, spontaneous passage time, and age were also not associated with any specific complications. For BB ingestion, all 5 cases with lithium batteries (≥1.5 cm, 3 V) presented moderate to major complications in the esophagus and stomach without any symptoms, even when the batteries were in the stomach and beyond the duodenum, while no complications were noted in 7 cases with alkaline batteries (<1.5 cm, 1.5 V) (p=0.001). All endoscopies were conducted within 24 hours after ingestion. Conclusion The type and voltage of the battery should be considered when determining whether endoscopy is required to remove a BB in the stomach. For lithium battery ingestion in young children, urgent endoscopic removal might be important in order to prevent complications, even if the child is asymptomatic and the battery is smaller than 2 cm.

    ObjectiveTo describe a new interventional technique to remove foreign bodies (FBs) embedded in soft tissues around vital vessels.MethodsUnder fluoroscopic guidance and using local anesthesia, percutaneous removal of FBs was performed using forceps in nine patients. All patients suffered from a metallic soft tissue FB located in close proximity to important vessels and one also had a small traumatic pseudoaneurysm adjacent to the FB. Prior to removal of the FB, the position of the nearest vessel was identified using a guide wire or catheter placed into the vessel. Balloon catheter was also simultaneously used to temporarily stop the blood flow of the nearest artery during the FB removal in three of the nine patients.ResultsAll of the nine FBs with 0–2 mm interval to the nearest vessel were successfully removed in the nine patients without any serious complications. The removed FBs measured 3–12 mm in length and 1–3 mm in width. The total fluoroscopic time of retrieval of each FB was 5–9 min (mean, 6.4 min). The volume of intraoperative bleeding ranged from 5 to 12 ml (mean, 7.5 ml). The length of hospital stay for each patient ranged from 4 to 8 days (mean, 5.5 days).ConclusionVascular intervention-aided percutaneous FB removal is minimally invasive and an effective method for removal of FBs around vital vessels.

    In this work, the foreign body reaction (FBR) to small subcutaneous implants was compared between small (rodent) and large (swine) animal species for the first time. Dexamethasone-releasing poly(lactic-co-glycolic acid) microspheres/polyvinyl alcohol hydrogel composite coatings were adapted to prevent FBR to small, subcutaneous implants in a large animal model (Goettingen minipigs). The implants consisted of small silicon chips (used to mimic small medical devices) that were coated with the composite formulations. The stages of the FBR were compared with previous studies in rats (that used the same-sized implants); the onset and severity of chronic inflammation (collagen deposition) was identified as a key difference between the two species. In the absence of inflammation control, fibrosis was observed from day 7 post-implantation in minipigs, whereas in rats this did not occur until day 14. This is significant as swine skin is the most commonly used model for preclinical testing of dermal formulations. It was determined that for long-term prevention of the FBR (longer than 24h), a lag phase in dexamethasone release between days 1 and 10 did not affect the anti-FBR properties of the implant in rats. However, continuous release of dexamethasone, with no lag phase, was necessary to prevent inflammation in minipigs (effective dexamethasone dose was 100μg delivered immediately after implantation and 10μg/day delivered continuously thereafter). This study offers significant insight into the translation of anti-FBR strategies across species, and showcases the importance of tailoring the controlled release kinetics of the formulation to the host response.

    Background Foreign bodies (FBs) in the upper gastrointestinal tract are produced chiefly by accidental swallowing but rarely produce symptoms. Removal of FBs is not an infrequent challenge for upper gastrointestinal endoscopy. The aim of this study is to elicit our experience in a 5-year period in dealing with FBs in the upper gastrointestinal tract using upper endoscopy. Methods This retrospective study was conducted at Zagazig University Hospitals, Egypt, over a 5-year period. We reviewed all patients’ files with full notations on age, sex, type of FB and its anatomical location, treatments, and outcomes (complications, success rates, and mortalities). Patients with incomplete files and those with FBs not identified at the endoscopic examination were excluded. Results A total of 45 patients were identified. Their ages ranged from 6 months to 102 years. Slight male predominance was noticed (53.3%). The most frequent presentation was a history of FB ingestion without any associated manifestations (44.4%). Coins were the most commonly encountered FBs (14/45). Esophagus was the most common site of trapping (27/45). The overall success rate was 95.6% (43/45). Upper endoscopy successfully resolved the problem by either FB removal (41/43) or dislodgment of the impacted fleshy meat to the stomach (2/43). Two cases were referred for surgical removal. The rate of complications was 6.7%. Furthermore, no mortalities due to FB ingestion or removal had been reported throughout the study. Conclusion Our experience with FB removal emphasizes its importance and ease when performed by experienced hands, at well-equipped endoscopy units, and under conscious sedation in most cases, with high success rates and minor complications.

    BACKGROUND: Airway foreign bodies (AFBs) is an interdisciplinary area between emergency medicine, pediatrics and otolaryngology. It is a life-threatening condition that is not infrequently seen; however, it is poorly covered in medical literature. Accidental aspiration of an element into airways is a widespread clinical scenario among children under 3 years, predominantly males. Moreover, it is the leading cause of infantile deaths and the fourth one among preschool children. DATA RESOURCES: A systemic search was conducted in July 2015 using PubMed/PubMed Central Database of The National Center for Biotechnology Information (NCBI) (http://www.ncbi.nlm.nih.gov/). A total of 1 767 articles were identified and most of them were meta-analyses, systematic reviews, and case series. Those thoroughly discussing assessment and management of AFBs were retrieved. RESULTS: AFBs episodes may be either witnessed or missed. Presence of a witness for the inhalation is diagnostic. The later usually present with persistent active cough. A classical triad of paroxysmal cough, wheezing, and dyspnoea/decreased air entry was reported, though many presentations have inconsistent findings. Hence, diagnosis requires high index of clinical suspicion. Flexible fibro-optic bronchoscopy is the gold standard of diagnosis, whereas inhaled objects are best retrieved by rigid bronchoscopes. CONCLUSIONS: Close supervision of pediatrics is the hallmark of prevention. Caregivers should ensure a safe surrounding milieu, including the toys their offspring play with. Immediate complications result from direct obstruction or injury by the inhaled object. Alternatively, prolonged lodging traps air and induces inflammatory response causing atelectesis and pneumonia, respectively. PMID:27006731

    Injury caused by biomedical device implantation initiates inflammatory and wound healing responses. Cells migrate to the site of injury to degrade bacteria and toxins, create new vasculature, and form new and repair injured tissue. Blood-proteins rapidly adsorb onto the implanted material surface and express adhesive ligands which mediate cell adhesion on the material surface. Monocyte-derived macrophages and multi-nucleated foreign body giant cells adhere to the surface and degrade the surface of the material. Due to the role of macrophage and foreign body giant cell on material biocompatibility and biostability, the effects of surface chemistry, surface topography and specific proteins on the maturation and survival of monocytes, macrophages and foreign body giant cells has been investigated. Novel molecularly designed materials were used to elucidate the dynamic interactions which occur between inflammatory cells, proteins and surfaces. The effect of protein and protein adhesion was investigated using adhesive protein depleted serum conditions on RGD-modified and silane modified surfaces. The effects of surface chemistry were investigated using temperature responsive surfaces of poly (N-isopropylacrylamide) and micropatterned surfaces of N-(2 aminoethyl)-3-aminopropyltrimethoxysilane regions on an interpenetrating polymer network of polyacrylamide and poly(ethylene glycol). The physical effects were investigated using polyimide scaffold materials and polyurethane materials with surface modifying end groups. The depletion of immunoglobulin G caused decreased levels of macrophage adhesion, foreign body giant cell formation and increased levels of apoptosis. The temporal nature of macrophage adhesion was observed with changing effectiveness of adherent cell detachment with time, which correlated to increased expression of beta1 integrin receptors on detached macrophages with time. The limited ability of the micropatterned surface, polyimide scaffold and surface

    A 39-year-old patient presented 3 days after a bicycle accident with a progressive left periorbital inflammatory swelling and diplopia in upgaze. On the day of the accident, a cranial x-ray did not reveal a fracture or an orbital foreign body, and the 2.5 cm skin wound on the left lower eyelid was sutured. For further evaluation, computer tomography) was performed. This did not show a radio-opaque, orbital foreign body. An explorative orbitotomy was carried out and revealed a 3.7 cm long wooden fragment medial to the inferior oblique muscle (OI). The extraconal portion of OI was found to be necrotic. Complete reconstruction of the OI was not possible due to the extent of the necrosis. The residual muscle was fixated to the orbital septum. Recovery was good and the diplopia resolved after 6 months. This case emphasizes the importance of a meticulous inspection of skin wounds with a high risk of remaining wooden foreign bodies and shows the possibility of functional recovery of extraocular muscles following partial reconstruction.

    Current imaging modalities face challenges in clinical applications due to limitations in resolution or contrast. Microwave-induced thermoacoustic imaging may provide a complementary modality for medical imaging, particularly for detecting foreign objects due to their different absorption of electromagnetic radiation at specific frequencies. A thermoacoustic tomography system with a multielement linear transducer array was developed and used to detect foreign objects in tissue. Radiography and thermoacoustic images of objects with different electromagnetic properties, including glass, sand, and iron, were compared. The authors' results demonstrate that thermoacoustic imaging has the potential to become a fast method for surgical localization of occult foreign objects.

    Video-assisted thoracic surgery (VATS) is widely adopted in acute management of patient with thoracic trauma, but its use in penetrating thoracic injuries with retained foreign bodies were rarely reported. We described three of such cases using VATS as the first line approach. Identification of injuries, control of bleeders, clot evacuation, resection of damaged lung parenchyma and safe retrieval of foreign bodies were all performed via complete VATS within short operative time. Patient were uneventfully discharged during early post-operative period. We suggest that, for haemodynamically stable patients, VATS offers a safe and minimally-invasive alternative to conventional thoracotomy for penetrating thoracic injury with retained foreign bodies.

    Background Daptomycin is a novel cyclic lipopeptide whose bactericidal activity is not affected by current antibiotic resistance mechanisms displayed by S. aureus clinical isolates. This study reports the therapeutic activity of high-dose daptomycin compared to standard regimens of oxacillin and vancomycin in a difficult-to-treat, rat tissue cage model of experimental therapy of chronic S. aureus foreign body infection. Methods The methicillin-susceptible S. aureus (MSSA) strain I20 is a clinical isolate from catheter-related sepsis. MICs, MBCs, and time-kill curves of each antibiotic were evaluated as recommended by NCCLS, including supplementation with physiological levels (50 mg/L) of Ca2+ for daptomycin. Two weeks after local infection of subcutaneously implanted tissue cages with MSSA I20, each animal received (i.p.) twice-daily doses of daptomycin, oxacillin, or vancomycin for 7 days, or was left untreated. The reductions of CFU counts in each treatment group were analysed by ANOVA and Newman-Keuls multiple comparisons procedures. Results The MICs and MBCs of daptomycin, oxacillin, or vancomycin for MSSA strain I20 were 0.5 and 1, 0.5 and 1, or 1 and 2 mg/L, respectively. In vitro elimination of strain I20 was more rapid with 8 mg/L of daptomycin compared to oxacillin or vancomycin. Twice-daily administered daptomycin (30 mg/kg), oxacillin (200 mg/kg), or vancomycin (50 mg/kg vancomycin) yielded bactericidal antibiotic levels in infected cage fluids throughout therapy. Before therapy, mean (± SEM) viable counts of strain I20 were 6.68 ± 0.10 log10 CFU/mL of cage fluid (n = 74). After 7 days of therapy, the mean (± SEM) reduction in viable counts of MSSA I20 was 2.62 (± 0.30) log10 CFU/mL in cages (n = 18) of daptomycin-treated rats, exceeding by >2-fold (P < 0.01) the viable count reductions of 0.92 (± 0.23; n = 19) and 0.96 (± 0.24; n = 18) log10 CFU/mL in cages of oxacillin-treated and vancomycin-treated rats, respectively.

    Abstract The purpose of this study was to investigate the clinical characteristic and visual outcome of siderosis bulbi with retained intraocular foreign body (IOFB) and to validate the predictive value of the Ocular Trauma Score (OTS) in siderosis bulbi. Certain numerical values rendered to the OTS variables at present were summated (Table 1) and converted into 5 OTS categories as performed in the OTS study. The prognostic value of OTS was first assessed in cases of siderosis bulbi resulting from a chemical reaction of retained IOFBs. Twenty-four eyes of 24 patients diagnosed with siderosis bulbi who underwent surgery between 2007 and 2013 at our medical centre were reviewed. Due to patients’ ignorance in ocular injuries, delayed presentation by the patient (54.17%) and no history of trauma (16.67%) were the most common cause of siderosis bulbi with IOFB retention. The main symptom of all these patients was impaired vision. The most common complications were cataract (23/24, 95.83%), followed by retinal pigmentary degeneration (15/22, 68.18%), iris heterochromia (14/24, 58.33%), pupillary mydriasis (10/21, 47.62%), secondary glaucoma (6/24, 25.00%), relative afferent pupillary defect (6/24, 25.00%), and retinal detachment (3/24, 12.50%). IOFBs were removed in 22 eyes (91.67%), except 2 enucleated eyes with absolute glaucoma (8.33%). Among all the patients (24 eyes), the best-corrected visual acuity improved in 63.64%, unchanged in 18.18% and deteriorated in 18.18% after surgical intervention. No statistically significant difference was found between the categorical distributions of our patients and those in the OTS study group. Further promotion and education on eye protection are needed to minimize visual loss from siderosis bulbi. The OTS, which was designed to predict visual outcomes of general ocular trauma, may also provide reliable information about the prognosis of siderosis bulbi resulting from a chemical reaction of retained IOFBs.

    Injectable scaffolds are of interest in the field of regenerative medicine because of their minimally invasive mode of delivery. For tissue repair applications, it is essential that such scaffolds have the mechanical properties, porosity and pore diameter to support the formation of new tissue. In the current study, porous poly(dl-lactic acid-co-glycolic acid) (PLGA) microspheres were fabricated with an average size of 84 ± 24 μm for use as injectable cell carriers. Treatment with ethanolic sodium hydroxide for 2 min was observed to increase surface porosity without causing the microsphere structure to disintegrate. This surface treatment also enabled the microspheres to fuse together at 37 °C to form scaffold structures. The average compressive strength of the scaffolds after 24 h at 37 °C was 0.9 ± 0.1 MPa, and the average Young’s modulus was 9.4 ± 1.2 MPa. Scaffold porosity levels were 81.6% on average, with a mean pore diameter of 54 ± 38 μm. This study demonstrates a method for fabricating porous PLGA microspheres that form solid porous scaffolds at body temperature, creating an injectable system capable of supporting NIH-3T3 cell attachment and proliferation in vitro.

    Hepatic abscess caused by foreign body penetration of the alimentary tract is rare. We report a case of gastric antrum penetration due to a toothpick complicated by liver abscess formation. A 41-year-old man was admitted to our hospital with the chief complaint of upper abdominal pain for 2 mo. Esophagogastroduodenoscopy performed at a local clinic revealed a toothpick penetrating the gastric antrum. Computed tomography (CT) of the abdomen at our hospital revealed a gastric foreign body embedded in the posterior wall of gastric antrum with regional phlegmon over the lesser sac and adhesion to the pancreatic body without notable vascular injury, and a hepatic abscess seven cm in diameter over the left liver lobe. Endoscopic removal of the foreign body was successfully performed without complication. The liver abscess was treated with parenteral antibiotics without drainage. The patient’s recovery was uneventful. Abdominal ultrasonography demonstrated complete resolution of the hepatic abscess six months after discharge. Relevant literature from the PubMed database was reviewed and the clinical presentations, diagnostic modalities, treatment strategies and outcomes of 88 reported cases were analyzed. The results showed that only 6 patients received conservative treatment with parenteral antibiotics, while the majority underwent either image-guided abscess drainage or laparotomy. Patients receiving abscess drainage via laparotomy had a significantly shorter length of hospitalization compared with those undergoing image-guided drainage. There was no significant difference in age between those who survived and those who died, however, the latter presented to hospitals in a more critical condition than the former. The overall mortality rate was 7.95%. PMID:24707157

    Introduction In rare cases, a foreign body may penetrate the thoracic cavity without the person’s awareness. I report a case of the traumatic intrathoracic foreign body of glass implants that the patient did not have awareness about. Presentation of case The 53-year-old woman was unsteady on her foot and leaned against the sliding door of the glass in a washroom. She fell unto a crashing glass panel sustained chest injury, and then she noticed bleeding from the left chest. Dyspnea and chest pain were emergent gradually. Chest Computed Tomography (CT) showed two foreign bodies which she did not complain of in a left pleural cavity. We performed an emergency video-assisted thoracic surgery by the diagnosis of traumatic hemopneumothorax and the foreign bodies. We could remove two glass pieces. Discussion I found 15 cases of intrathoracic foreign body without the patient's awareness in a Japanese medical central magazine for the years 1993–2015. In some cases identifying a glass piece on perioperative X-rays may be difficult. Thus, all means for determining the accurate number of glass pieces and their approximate positions should be used, including multi-slice CT. I realize that a preoperative strategy is also important. Conclusion The patients who injured the chest with the glass without awareness of the implant of the foreign body, we take an intrathoracic foreign body by the penetration of the glass piece into consideration, need the search by the imaging. The extraction of the glass foreign bodies by VATS is very useful. PMID:27111874

    Foreign body gingivitis has been described as an inflammatory reaction of marginal or attached gingival tissues due to foreign material in the connective tissue. This article presents the case of a 58-year-old woman with the chief complaint of periodic discomfort in her maxillary "gums" and redness in the facial gingival tissues of the maxillary anterior segment. A biopsy showed a granulomatous reaction in both the red and neutral areas. The patient revealed that she had been using a water jet device on a high pressure setting. She was advised to discontinue the water jet use, after which the gingival redness and inflammation began to subside, and appeared normal at 3- and 6-month follow-up visits. PMID:25184713

    Foreign language education in the twenty-first century still teaches vocabulary mainly through reading and listening activities. This is due to the link between teaching practice and traditional philosophy of language, where language is considered to be an abstract phenomenon of the mind. However, a number of studies have shown that accompanying words or phrases of a foreign language with gestures leads to better memory results. In this paper, I review behavioral research on the positive effects of gestures on memory. Then I move to the factors that have been addressed as contributing to the effect, and I embed the reviewed evidence in the theoretical framework of embodiment. Finally, I argue that gestures accompanying foreign language vocabulary learning create embodied representations of those words. I conclude by advocating the use of gestures in future language education as a learning tool that enhances the mind. PMID:25538671

    Fifty odd years ago, in his historic book, 'The Silent World,' Jacques Cousteau told us that scuba divers breathing compressed air were apt to get a 'high,' which he called, 'Rapture of the Deep,' and a form of cerebral arrest, which he termed, 'Nitrogen Narcosis'. Furthermore, these submarine soloists, also like persons under general anesthesia, are prone to mysterious sudden death. All this reminds us of 'ether parties,' and contemporary snorters and huffers, sniffing such foreign bodies as, glue, cocaine, paint-thinner, gasoline, spray-can-propellant, etc. Relevant is the fact that the endogenous and other soporifics which arise within the body proper (endo-integumentarily) do not induce general anesthesia, which is cerebral arrest, until they have entered the extra-integumentary mucosal compartments called airways. Nitrogen is an inert gas, so its actions are neither toxic nor chemical, but mechanical. The effects of endogenous soporifics such as acetone, carbon dioxide, alcohol, and ammonia, are usually assumed to be toxic and endo-integumentary. Therefore, I must emphasize the fact that they do not cause 'Highs,' somnolence, nor deaths until/unless they have entered the extra-integumentary airways. Certainly those agents may also have some endo-integumentary actions. I must also stress the fact that foreign bodies in the airways which do not pierce the integument to enter the body proper, such as endotracheal or tracheostomy tubes, lumps of meat, mucus plugs (boogers), etc., can also occasionally trigger cerebral, respiratory and even cardiac arrests locally and mechanically in the airways, depending on which trigger points they stimulate and how powerfully. Four points explain the mechanism of general anesthesia: (a) Endogenous soporifics do not induce sleep until they have entered the extra-integumentary airways, and contacted the mural mucosa; (b) however administered, intravenously, rectally, or by inhalation, exogenous general agents do not anesthetize

    Background Diagnostic and therapeutic instrumentation of the lower gastrointestinal tract has been reported to result in bacteremia and endocarditis. No such case has been reported in persons with a history of rectal foreign body insertion despite its potential for greater trauma. Case presentation A 58-year-old male was admitted with confusion and inability to speak. His past history was notable for hospitalization to extract a retained plastic soda bottle from the rectosigmoid two years prior. On examination, he was febrile, tachycardic and hypotensive. There was an apical pansystolic murmur on cardiac examination. He had a mixed receptive and expressive aphasia, and a right hemiparesis. On rectal examination he had perianal erythema and diminished sphincter tone. Magnetic resonance imaging of the brain showed infarction of the occipital and frontal lobes. Transesophageal Echocardiography of the heart revealed vegetations on the mitral valve. All of his blood culture bottles grew methicillin sensitive Staphylococcus aureus. He was successfully treated for bacterial endocarditis with intravenous nafcillin and gentamicin. The rectum is frequently colonized by Staphylococcus aureus and trauma to its mucosa can lead to bacteremia and endocarditis with this organism. In the absence of corroborative evidence such as presented here, it is difficult to make a correlation between staphylococcal endocarditis and anorectal foreign body insertion due to patients being less than forthcoming Conclusion There is a potential risk of staphylococcal bacteremia and endocarditis with rectal foreign body insertion. Further studies are needed to explore this finding. Detailed sexual history and patient counseling should be made a part of routine primary care. PMID:15921523

  9. The role of chemical mediators in the inflammatory response induced by foreign bodies: comparison with the schistosome egg granuloma.

    Kellermeyer, R W; Warren, K S

    1970-01-01

    Both divinyl benzene copolymer (plastic) beads and schistosome eggs produce inflammatory reactions after intravenous deposition into the lung of a mouse. As reported previously, the schistosome egg granuloma is an immunologic reaction of the delayed hypersensitivity type; this inflammatory process is prevented by immunosuppressive measures, and characteristically demonstrates an anamnestic response. In contradistinction, the plastic bead granuloma appears to be characteristic of a foreign body reaction; it is unaffected by immunosuppressive measures and does not demonstrate an anamnestic response with repeated exposure. The data in this report suggest that the granuloma formation around plastic beads is a nonimmunologic reaction induced by chemical mediators of inflammation. This proposal is supported by the following findings: the plastic beads activate Hageman factor in normal human and mouse plasma; the plastic beads induce vascular permeability-enhancing activity as measured in guinea pig skin and kinin-like activity in normal human and mouse plasma that is dependent on Hageman factor; ellagic acid, an agent that activates Hageman factor in vivo and is reported to diminish kininogen by consumptive depletion, markedly depresses the plastic bead granuloma. These data are consistent with the idea that the plastic bead granuloma and perhaps other foreign body inflammatory reactions are in major part dependent on kinin formation. Ellagic acid also suppressed the schistosome egg granuloma, but not to the same degree as the plastic bead granuloma. The implications of this observation are discussed in the text. Silicosis and "blue velvet disease", pathologic processes associated with the deposition of silica and magnesium trisilicate, respectively, in the lung, and the induction of a foreign body reaction may also be dependent on the activation of chemical mediators of inflammation by the silica and magnesium trisilicate particles with immunologic mechanisms

    Percutaneous nephrolithotomy (PNL) is the first-line treatment in large, multiple stones and lower calyceal stones. Majority of complications associated with PNL are minor and clinically insignificant. It was seen that distal piece (2 cm in size) of ureter catheter observed at pelvis was found at the parenchyma of left lung on the perioperative fluoroscopy in the patient undergoing PNL for right kidney stone. We presented this complication to stress that a foreign body can pass into circulation presumably through venous injury and can migrate to the lung. PMID:26171308

    The mucopolysaccharidosis (MPS) is a rare lysosomal storage disease. Glycosaminoglycans (GAG) accumulate in musculoskeletal system, connective tissues. Enlarged tongue, short immobile neck, and limited mobility of the cervical spine and temporomandibular joints render the airway management potentially risky. MPS children have high anesthetic risks, especially in airway management of emergency situations. The foreign-body aspiration requiring intervention with rigid bronchoscopy is an urgent and risky clinical situation. We present our experience with a challenging airway management with a three-year-old child with MPS who needed emergency bronchoscopy due to peanut aspiration. PMID:27146659

    Penile foreign body injection is an uncommon entity produced by penile paraffin, mineral oil, and vaseline injections for the purpose of penile enlargement. Generally, penile subcutaneous and glandular injections for penile augmentation are performed by a nonmedical person, under unacceptable conditions. It will be an aim to share our experiences about penile vaseline injection. PMID:23213616

    Hydrogels may be the ideal vitreous substitutes due to their wonderful physical features and biocompatibility. However, their drawbacks, short residence time, and biodegradation in vivo, have led to the fact that none of them have been approved for clinical use. In this study, we developed a novel approach of using a foldable capsular vitreous body (FCVB) injected with polyvinylalcohol (PVA) hydrogel as a vitreous substitute for long-term tamponade. The 3% PVA hydrogel that was cross-linked by gamma irradiation showed good rheological and physical properties and had no toxicity in vitro. After 180 days retention, the 3% PVA hydrogel inside FCVB remained transparent and showed good viscoelasticity without biodegradation and showed good biocompatibility and retina support. This new approach may develop into a valuable tool to improve the stability performance of PVA hydrogel as a vitreous substitute and to extend the application function of FCVB for long-term implantation in vitreous cavity.

    Macrophages that are recruited to the site of implanted biomaterials undergo fusion to form surface-damaging foreign body giant cells. Exposure of peripheral blood monocytes to interleukin-4 can recapitulate the fusion process in vitro. In this study, we used interleukin-4 to induce multinucleation of murine bone marrow-derived macrophages and observed changes in cell shape, including elongation and lamellipodia formation, before fusion. Because cytoskeletal rearrangements are regulated by small GTPases, we examined the effects of inhibitors of Rho kinase (Y-32885) and Rac activation (NSC23766) on fusion. Y-32885 did not prevent cytoskeletal changes or fusion but limited the extent of multinucleation. NSC23766, on the other hand, inhibited lamellipodia formation and fusion in a dose-dependent manner. In addition, we found that in control cells, these changes were preceded by Rac1 activation. However, NSC23766 did not block the uptake of polystyrene microspheres. Likewise, short interfering RNA knockdown of Rac1 limited fusion without limiting phagocytosis. Thus, phagocytosis and fusion can be partially decoupled based on their susceptibility to NSC23766. Furthermore, poly(ethylene-co-vinyl acetate) scaffolds containing NSC23766 attenuated foreign body giant cell formation in vivo. These observations suggest that targeting Rac1 activation could protect biomaterials without compromising the ability of macrophages to perform beneficial phagocytic functions at implantation sites.

    The aim of this study is to report our experience in the diagnosis and treatment of tracheobronchial foreign bodies (TFBs). We retrospectively reviewed medical records of 2,000 TFB patients (1,260 males and 740 females) who were treated between January 2010 and December 2013. Chest radiography and computed tomography were performed to diagnose TFBs. The location and type of foreign bodies (FBs), anesthesia methods, and treatment outcomes and complications were analyzed. Overall, 72.5% of our patients with TFB were aged between 1 years and 3 years. Plant-based FBs are the most common FB type, accounting for 91.5%. Almost 52.1% of the FBs were encountered in the right bronchus. The coincidence rate for computed tomography-based three-dimensional reconstruction was significantly greater than that for chest X-ray examination (98.7% vs 82.0%, P<0.01). Under general anesthesia, the FBs were removed by rigid bronchoscopy. Neither anesthesia complication nor intraoperative hypoxemia occurred. There were seven deaths from acute obstructive asphyxia and eight from residual FB-induced chronic asphyxia and respiration-circulation failure. In conclusion, early diagnosis and prompt treatment of TFBs with rigid bronchoscopy under general anesthesia is effective in reducing complications and mortality in affected children. PMID:26357477

    Implantation of biomaterials elicits a foreign body response characterized by fusion of macrophages to form foreign body giant cells and fibrotic encapsulation. Studies of the macrophage polarization involved in this response have suggested that alternative (M2) activation is associated with more favorable outcomes. Here we investigated this process in vivo by implanting mixed cellulose ester filters or polydimethylsiloxane disks in the peritoneal cavity of wild-type (WT) and monocyte chemoattractant protein-1 (MCP-1) knockout mice. We analyzed classical (M1) and alternative (M2) gene expression via quantitative polymerase chain reaction, immunohistochemistry and enzyme-linked immunosorbent assay in both non-adherent cells isolated by lavage and implant-adherent cells. Our results show that macrophages undergo unique activation that displays features of both M1 and M2 polarization including induction of tumor necrosis factor α (TNF), which induces the expression and nuclear translocation of p50 and RelA determined by immunofluorescence and Western blot. Both processes were compromised in fusion-deficient MCP-1 KO macrophages in vitro and in vivo. Furthermore, inclusion of BAY 11-7028, an inhibitor of NFκB activation, reduced nuclear translocation of RelA and fusion in WT macrophages. Our studies suggest that peritoneal implants elicit a unique macrophage polarization phenotype leading to induction of TNF and activation of the NFκB pathway. PMID:25242651

    We present the analysis and decomposition of tire radiography images by combining the total variation, curvelet transform based image enhancement, and Canny edge detection to detect foreign bodies and bubble defects in tires. Relying on the feature of total variation that images can be decomposed as texture parts and cartoon parts, we decompose the tire radiography image and select the cartoon part for defect detection since the textures are segmented and defect information is retained. The edges of the image are enhanced by modifying the curvelet coefficients before further edge detection operation. Furthermore, a Canny edge detection operator is used to detect the defects in which the eight-neighborhood bilinear interpolation non-maximum suppression method is employed to improve the detection performance. In our experiments, the Sobel operator and state-of-the-art methods such as the LoG operator and Canny edge detection algorithms are employed for comparison, and the experimental results are discussed briefly. The experimental results indicate that foreign bodies and bubbles in tires can be detected and located accurately by our proposed method.

    This is a descriptive case report of a seven-year-old boy presented in January 2007 with decreased vision in the right eye, for 2 months after sustaining a trauma while he was playing with fireworks during the Eid holiday. He was treated in a suburban hospital for corneal laceration and was prescribed a topical antibiotic and a topical steroid. When the child presented to us, a slit lamp examination revealed a thread in the anterior chamber, his un-aided visual acuity was 6/60 on a Snellen chart. Surgery to remove the foreign body was scheduled, but the patient never attended. The patient was lost to follow-up and returned in January 2011 with an un-aided visual acuity of 6/12, although the foreign body was retained in the anterior chamber (AC) with a quiet eye and good vision. At that time, we decided to follow the patient without any surgical intervention. Again, the patient was lost to follow-up and returned with almost full vision in September 2012, with a visual acuity of 6/6 without correction. Thus, we concluded that thread like IOFBs in the AC can be considered inert materials that may not need any surgical intervention in a quiet eye that does not show any signs of inflammation and where the IOFB is non-mobile and located away from the endothelium.

    This study investigated the degree to which body habitus influences radiation dose during CT fluoroscopy (CTF)-guided lumbar epidural steroid injections (ESI). An anthropomorphic phantom containing metal oxide semiconductor field effect transistor (MOSFET) detectors was scanned at two transverse levels to simulate upper and lower lumbar CTF-guided ESI. Circumferential layers of adipose-equivalent material were sequentially added to model patients of three sizes: small (cross-sectional dimensions 25×30 cm), average (34×39 cm), and oversize (43×48 cm). Point dose rates to skin and internal organs within the CTF beam were measured. Scattered point dose rates 5 cm from the radiation beam were also measured. Direct point dose rates to the internal organs ranged from 0.05-0.11 mGy/10mAs in the oversized phantom, and from 0.18-0.43 mGy/10mAs in the small phantom. Skin direct point dose rates ranged from 0.69-0.71 mGy/10mAs in the oversized phantom and 0.88-0.94 mGy/10mAs in the small phantom. This represents a 180-310% increase in organ point dose rates and 24-36% increase in skin point dose rates in the small habitus compared with the oversize habitus. Scatter point dose rates increased by 83-117% for the small compared to the oversize phantom. Decreasing body habitus results in substantial increases in direct organ and skin point doses as well as scattered dose during simulated CTF-guided procedures. Failure to account for individual variations in body habitus will result in inaccurate dose estimation and inappropriate choice of tube current in CTF-guided procedures. PMID:25363254

    A 6-year-old entire male cat was presented with a 1-week history of severe dyspnoea without coughing. Upon auscultation, an inspiratory and particularly pronounced expiratory wheeze was noted, with severe dyspnoea. The minimum database was normal. Plain thoracic radiographs showed signs of a mural or intraluminal intrathoracic (T1-T4) tracheal narrowing. A dynamic collapsing trachea was ruled out using fluoroscopy. Bronchoscopy was performed and a dark green and brown spiculated foreign object was found just cranial to the carina. Following removal, the cat rapidly developed extensive truncal subcutaneous emphysema and oxygen-responsive dyspnoea and cyanosis. Follow-up radiographs demonstrated unilateral pneumothorax and lung collapse, marked pneumomediastinum and dissection of air through the tracheal wall. A thoracic drain was placed and the pneumothorax resolved rapidly. Follow-up radiographs demonstrated resolution of pneumothorax and development of extensive retroperitoneal air. The cat made an uneventful recovery. The foreign object was the calyx and stem of a flower. This article emphasises the importance of diagnostic imaging in the dyspnoeic patient, both for confirming initial suspicions of respiratory tract disease, and in managing and charting post-therapy resolution or complications.

    A 68-year-old man presented with the chief complaint of swelling of the penis. A pencil had been inserted into his urethra by a commercial sex worker for sexual stimulation. On a computed tomography (CT) scan, a foreign object was visible throughout the urethra and in the urinary bladder. Cystoscopy performed under spinal anesthesia showed a pencil in the urethra. We attempted removing the object endoscopically by using a Holmium laser. However, the endoscopic procedure failed and finally, we removed the object by transvesical open surgery. At the same time, suprapubic cystostomy was performed for the disorder of the urethra. An anterior urethrocutaneous fistula was formed 5 days after the operation. After removal of the urethral catheter, he was managed with only suprapubic cystostomy. Conservative management of the urethrocutaneous fistula was effective. The fistula was completely closed 26 days after the operation. He was discharged 33 days after the operation. PMID:27569356

    A 13-year-old female is presented. When she was six years old, she had fallen, holding wooden chopsticks and got stuck with a chopstick in the right upper eyelid. She was brought to a physician immediately, but a residual foreign body was missed and no particular symptom had developed during 7 years. She visited our department with fever and headache, and a brain abscess and an intracranial foreign body were found on computed tomography (CT) and magnetic resonance image (MRI) 7 years after the penetrating injury. She underwent removal of the object and abscess by craniotomy and recovered without neurological abnormalities. Since intracranial retained wooden foreign bodies frequently cause delayed complications of severe central nervous system infection, surgical removal is necessary even in the absence of symptoms.

    The prophylactic and therapeutic activities of teicoplanin were evaluated in two different experimental models of foreign body infections caused by methicillin-resistant Staphylococcus aureus (MRSA). In a guinea pig model of prophylaxis, subcutaneously implanted tissue cages were infected at a > 90% rate by 10(2) CFU of MRSA in control animals. A single dose of 30 mg of teicoplanin per kg of body weight administered intraperitoneally 6 h before bacterial challenge was as effective as vancomycin in preventing experimental infection in tissue cages injected with either 10(2), 10(3), or 10(4) CFU of MRSA. In a rat model evaluating the therapy of chronic tissue cage infection caused by MRSA, the efficacy of a 7-day high-dose (30 mg/kg once daily) regimen of teicoplanin was compared with that of vancomycin (50 mg/kg twice daily). Whereas high levels of teicoplanin were found in tissue cage fluid, continuously exceeding its MBC for MRSA by 8- to 16-fold, no significant reduction in the viable counts of MRSA occurred during therapy. In contrast, either vancomycin alone or a combined regimen of high-dose teicoplanin plus rifampin (25 mg/kg twice daily) could significantly decrease the viable counts in tissue cage fluids. Whereas the bacteria recovered from tissue cage fluids during therapy showed no evidence of teicoplanin resistance, they failed to be killed even by high levels of this antimicrobial agent. The altered susceptibility of in vivo growing bacteria to teicoplanin killing might in part explain the defective activity of this antimicrobial agent when used as monotherapy against chronic S. aureus infections. These data may indicate the need for a combined regimen of teicoplanin with other agents such as rifampin to optimize the therapy of severe staphylococcal infections. PMID:7985998

    Today orthodontic treatment is in growing demand and is not limited to a specific age or social group. The nature of orthodontic treatment is such that the orthodontic wires and appliances, which are used to apply force and move the teeth, are exposed to the oral cavity. Shaping and replacing these wires in oral cavity are the major assignments of orthodontist on appointments. Therefore, we can say that orthodontic treatment requires working with dangerous tools in a sensitive place like oral cavity which is the entrance of respiratory and digestive systems. In this paper, a case of ingesting a broken orthodontic wire during eating is reported, and also necessary remedial measures at the time of encountering foreign body ingestion or aspiration are provided.

    We report a case of a laryngectomized patient who accidentally aspirated a wooden stick through his tracheal stoma in highly unusual circumstances. He was in a habit of cleaning secretions of upper airway with a wooden stick covered with cotton on the tip soaked in olive oil, via tracheostomy. After applying topical aerolized lidocaine spray through the tracheostomy stoma a flexible video-brochoscopy was performed and a tree twig over 11 cm in length was removed. The patient's symptoms were resolved by a bronchoscopy. With experience and availability of accessories, the removal of the foreign body using flexible bronchoscope under local anesthesia can be performed safely and successfully. This case suggests that the physicians and otolaryngologists should educate their laryngectomized patients about stomal care and discuss any potential life-threatening situation they might encounter.

    The therapeutic activity of ceftobiprole medocaril, the water-soluble prodrug of ceftobiprole, was compared to that of vancomycin in a rat tissue cage model of chronic methicillin-resistant Staphylococcus aureus (MRSA) foreign-body infection. The MICs and MBCs of ceftobiprole and vancomycin in Mueller-Hinton broth for strain MRGR3 were 1 and 4 and 1 and 2 μg/ml, respectively. In vitro elimination rates of strain MRGR3 of 4 and 8 μg/ml of ceftobiprole or vancomycin were equivalent. After 2 weeks of infection, mean ± standard error of the mean viable counts of strain MRGR3 were 6.83 ± 0.11 log CFU/ml of tissue cage fluid (n = 87). High-dose regimens of ceftobiprole medocaril (equivalent to 150 mg/kg of ceftobiprole) or 50 mg/kg vancomycin produced nearly identical average peak and trough levels of ceftobiprole and vancomycin in tissue cage fluid, which exceeded the MBC of either antibiotic towards strain MRGR3 for ≥75% of each dosing interval. After 7 days of therapy with ceftobiprole medocaril or vancomycin, average counts of MRGR3 decreased significantly (P < 0.02) by 0.68 ± 0.28 (n = 29) and 0.88 ± 0.22 (n = 28) log CFU/ml of tissue cage fluid, respectively, compared with cages of untreated animals, but were not significantly different from each other. No resistant mutants were detected on ceftobiprole-supplemented agar following therapy with this cephalosporin. The in vivo activity of ceftobiprole medocaril against chronic MRSA foreign-body infections was equivalent to that of vancomycin and did not lead to the emergence of resistant subpopulations.

    Chronic brain implants are accompanied by a tissue response that causes the loss of neurons in the vicinity of the implant and the formation of a glial scar that is also referred to as foreign body response. Despite immense progress in the field of brain-computer interface (BCI) research the biocompatibility of chronic brain implants remains a primary concern in device design. Excitotoxic overstimulation of NMDA-receptors by extrasynaptic glutamate plays a pivotal role in cell death in the acute phase of the tissue reaction. In this study, we examined the effect of the uncompetitive NMDA-receptor antagonist memantine locally applied during cannula implantation in the caudal forelimb area (CFA) of the motor cortex (M1) in Lister Hooded rats on their behavioural performance in a skilled reaching and a rung-ladder task as well as in the open field. Moreover, the distribution of neurons and glial cells in the vicinity of the implant were assessed. Memantine improved the performance in the behavioural paradigms compared to controls and increased the number of surviving neurons in the vicinity of the implant even above basal levels accompanied by a reduction in astrocytic scar formation directly around the implant with no effect on the microglia/macrophage activation two and six weeks after cannula implantation. These findings suggest that memantine is a potential therapeutic agent in the acute phase of chronic foreign body implantation in the motor cortex in terms of increasing the viability of neurons adjacent to the implant and of improving the behavioural outcome after surgery.

    Mast cells (MCs)_are recognized for their functional role in wound-healing and allergic and inflammatory responses - host responses that are frequently detrimental to implanted biomaterials if extended beyond acute reactivity. These tissue reactions impact especially on the performance of sensing implants such as continuous glucose monitoring (CGM) devices. Our hypothesis that effective blockade of MC activity around implants could alter the host foreign body response (FBR) and enhance the in vivo lifetime of these implantable devices motivated this study. Stem cell factor and its ligand c-KIT receptor are critically important for MC survival, differentiation and degranulation. Therefore, an MC-deficient sash mouse model was used to assess MC relationships to the in vivo performance of CGM implants. Additionally, local delivery of a tyrosine kinase inhibitor (TKI) that inhibits c-KIT activity was also used to evaluate the role of MCs in modulating the FBR. Model sensor implants comprising polyester fibers coated with a rapidly dissolving polymer coating containing drug-releasing degradable microspheres were implanted subcutaneously in sash mice for various time points, and the FBR was evaluated for chronic inflammation and fibrous capsule formation around the implants. No significant differences were observed in the foreign body capsule formation between control and drug-releasing implant groups in MC-deficient mice. However, fibrous encapsulation was significantly greater around the drug-releasing implants in sash mice compared to drug-releasing implants in wild-type (e.g. MC-competent) mice. These results provide insights into the role of MCs in the FBR, suggesting that MC deficiency provides alternative pathways for host inflammatory responses to implanted biomaterials. PMID:24406200

    The QR regressor tumour (QR-32), a fibrosarcoma which is unable to grow progressively in normal syngeneic C57BL/6 mice, was able to grow progressively in 13 out of 22 mice (59%) when it was subcutaneously coimplanted with gelatin sponge. We established four culture tumour lines from the resultant tumours (QRsP tumour lines). These QRsP tumour lines were able to grow progressively in mice even in the absence of gelatin sponge. The ability of QRsP tumour cells to colonise the lungs after intravenous injection and to produce high amounts of prostaglandin E2 (PGE2) during in vitro cell culture was much greater than that of parent QR-32 cells. These biological characteristics of QR-32 cells and QRsP tumour cells were found to be stable for at least 6 months when they were maintained in culture. We also observed that QR-32 cells were able to grow progressively in five out of 12 (42%) mice after coimplantation with plastic non-adherent peritoneal cells obtained from mice which had been intraperitoneally implanted with gelatin sponge. These host cells reactive to gelatin sponge increased the production of high amounts of PGE2 by QR-32 cells during 48 h coculture. Preliminary in vitro studies implicated the involvement of hydrogen peroxide and hydroxyl radical as some of the factors necessary to induce QR-32 cells to produce high amounts of PGE2 and to accelerate tumour progression.

    Introduction A foreign body (FB) is an object or substance foreign to the location where it is found. FBs in the ear, nose, and throat are a common problem frequently encountered in both children and adults. Objective To analyze FBs in terms of type, site, age, and gender distribution and method of removal. Methods A retrospective study was performed in a tertiary care hospital in the central part of Nepal. The study period was from June 2013 to May 2014. The information was obtained from hospital record books. Results A total of 134 patients had FBs in the ear, nose, or throat; 94 were males and 40 were females. Of the 134 patients, 70 (52.23%) had FB in the ear, 28 (20.89%) in the nose, and 36 (26.86%) in the throat. The FB was animate (living) in 28 (40%) patients with FB in the ear and 1 (3.5%) patient with FB in the nose, but the FB was inanimate (nonliving) in any patient with FB in the throat, in 42 (60%) patients with FB in the ear FB, and in 27 (96.4%) patients with FB of the nose. The FB was removed with or without local anaesthesia (LA) in 98 (73.13%) patients, and only 36 patients (26.86%) required general anaesthesia (GA). The most common age group affected was <10 years. Conclusion FBs in the ear and nose were found more frequently in children, and the throat was the most common site of FB in adults and elderly people. Most of the FBs can be easily removed in emergency room or outpatient department. PMID:25992166

Conclusion FBs in the ear and nose were found more frequently in children, and the throat was the most common site of FB in adults and elderly people. Most of the FBs can be easily removed in emergency room or outpatient department. PMID:25992166

    Despite the use of daptomycin alone at high doses (greater than 6 mg/kg of body weight/day) against difficult-to-treat infections, clinical failures and resistance appeared. Recently, the combination daptomycin-cloxacillin showed enhanced efficacy in clearing bacteremia caused by methicillin-resistant Staphylococcus aureus (MRSA). The aim of this study was to evaluate the efficacy of daptomycin at usual and high doses (equivalent to 6 and 10 mg/kg/day in humans, respectively) in combination with cloxacillin in a rat tissue cage infection model by MRSA and to compare its efficacy to that of daptomycin-rifampin. We used MRSA strain ATCC BAA-39. In the log- and stationary-phase kill curves, daptomycin-cloxacillin improved the bactericidal activity of daptomycin, especially in log phase. For in vivo studies, therapy was administered intraperitoneally for 7 days with daptomycin at 100 mg/kg/day and 45/mg/kg/day (daptomycin 100 and daptomycin 45), daptomycin 100-cloxacillin at 200 mg/kg/12 h, daptomycin 45-cloxacillin, and daptomycin 100-rifampin at 25 mg/kg/12 h. Daptomycin-rifampin was the best therapy (P < 0.05). Daptomycin 45 was the least effective treatment and did not protect against the emergence of resistant strains. There were no differences between the two dosages of daptomycin plus cloxacillin in any situation, and both protected against resistance. The overall effect of the addition of cloxacillin to daptomycin was a significantly greater cure rate (against adhered bacteria) than that for daptomycin alone. In conclusion, daptomycin-cloxacillin enhanced modestly the in vivo efficacy of daptomycin alone against foreign-body infection by MRSA and was less effective than daptomycin plus rifampin. The benefits of adding cloxacillin to daptomycin should be especially evaluated against infections by rifampin-resistant MRSA and for protection against the emergence of daptomycin nonsusceptibility.

    Ingestion/aspiration episodes of foreign bodies are potential complications in almost all branches of dentistry. Occasionally, orthodontic appliances or small orthodontic components are accidentally swallowed and have caused problems with either the airway or the gastrointestinal tract, especially where the patient is supine or semi-recumbent. Despite their rare occurrence, the morbidity from a single incident and the level of specialized medical care that may be needed on emergency basis to manage such incidents is too high to ignore. Moreover, there is also the related risk of malpractice litigation given the fact that these incidents are preventable and increasing awareness among people. This article attempts to review potential risks and complications of ingestion/aspiration episodes based on relevant literature and describe the type of appliances and their parts most likely to cause problems. Certain recommendations based on best available evidence to minimize the incidence of such events are proposed, and strategies to aid the clinician in the event of such an emergency are also formulated.

    We report on the performance of composite nerve grafts with an inner 3D multichannel porous chitosan core and an outer electrospun polycaprolactone shell. The inner chitosan core provided multiple guidance channels for regrowing axons. To analyze the in vivo properties of the bare chitosan cores, we separately implanted them into an epineural sheath. The effects of both graft types on structural and functional regeneration across a 10 mm rat sciatic nerve gap were compared to autologous nerve transplantation (ANT). The mechanical biomaterial properties and the immunological impact of the grafts were assessed with histological techniques before and after transplantation in vivo. Furthermore during a 13-week examination period functional tests and electrophysiological recordings were performed and supplemented by nerve morphometry. The sheathing of the chitosan core with a polycaprolactone shell induced massive foreign body reaction and impairment of nerve regeneration. Although the isolated novel chitosan core did allow regeneration of axons in a similar size distribution as the ANT, the ANT was superior in terms of functional regeneration. We conclude that an outer polycaprolactone shell should not be used for the purpose of bioartificial nerve grafting, while 3D multichannel porous chitosan cores could be candidate scaffolds for structured nerve grafts.

    Qualitative research is lacking regarding the experiences of magnetic resonance imaging (MRI) technologists and their involvement in workplace safety practices. This article provides a gateway to explore, describe and document experiences of MRI technologists in New Zealand (NZ) pertaining to intra-orbital metallic foreign body (IMFB) safety practices. This phenomenological study describes the experiences of seven MRI technologists all with a minimum of 5 years' NZ work experience in MRI. The MRI technologists were interviewed face-to-face regarding their professional IMFB workplace experiences in order to explore historical, current and potential issues. Findings demonstrated that aspects of organization and administration are fundamentally important to MRI technologists. Varying levels of education and knowledge, as well as experience and skills gained, have significantly impacted on MRI technologists’ level of confidence and control in IMFB practices. Participants’ descriptions of their experiences in practice regarding decision-making capabilities further highlight the complexity of these themes. A model was developed to demonstrate the interrelated nature of the themes and the complexity of the situation in totality. Findings of this study have provided insight into the experiences of MRI technologists pertaining to IMFB safety practices and highlighted inconsistencies. It is hoped that these findings will contribute to and improve the level of understanding of MRI technologists and the practices and protocols involved in IMFB safety screening. The scarcity of available literature regarding IMFB safety practices highlights that more research is required to investigate additional aspects that could improve MRI technologists’ experiences.

    Purpose: This study assessed the contribution of ahyaluronic acid (HA) injection between the rectum and the prostate to reducing the dose to the rectal wall in stereotactic body radiation therapy (SBRT). Methods and Materials: As part of a phase 2 study of hypofractionated radiation therapy (62 Gy in 20 fractions), the patients received a transperineal injection of 10 cc HA between the rectum and the prostate. A dosimetric computed tomographic (CT) scan was systematically performed before (CT1) and after (CT2) the injection. Two 9-beam intensity modulated radiation therapy-SBRT plans were optimized for the first 10 patients on both CTs according to 2 dosage levels: 5 × 6.5 Gy (PlanA) and 5 × 8.5 Gy (PlanB). Rectal wall parameters were compared with a dose–volume histogram, and the prostate–rectum separation was measured at 7 levels of the prostate on the center line of the organ. Results: For both plans, the average volume of the rectal wall receiving the 90% isodose line (V90%) was reduced up to 90% after injection. There was no significant difference (P=.32) between doses received by the rectal wall on CT1 and CT2 at the base of the prostate. This variation became significant from the median plane to the apex of the prostate (P=.002). No significant differences were found between PlanA without HA and PlanB with HA for each level of the prostate (P=.77, at the isocenter of the prostate). Conclusions: HA injection significantly reduced the dose to the rectal wall and allowed a dose escalation from 6.5 Gy to 8.5 Gy without increasing the dose to the rectum. A phase 2 study is under way in our department to assess the rate of acute and late rectal toxicities when SBRT (5 × 8.5 Gy) is combined with an injection of HA.

    The aim of this study was to examine the chronic effects and mode of action of doxorubicin in ocular tissues. A dose of 10 microg (17.24 nanomoles) of doxorubicin hydrochloride in 20 microl sterile saline were intravitreally injected, under local anaesthesia, in one eye of 13 rabbits and 50 microg (86.20 nanomoles) were similarly injected in one eye of 3 rabbits. The contralateral eye received 20 microl of saline only. The dose of 50 microg induced initially mild uveal inflammation which became chronic and turned into circular iritis. Both doses of the drug induced cataract of the lens and clouding of the cornea within 2-3 months. The activity of superoxide dismutase, in iris-ciliary bodies and lenses treated with either 10 or 50 microg of the compound, was significantly lower relative to that in respective control tissues. In contrast to superoxide dismutase, catalase showed an increased activity in experimental tissues relative to control. The lysosomal hydrolases acid phosphatase, N-acetyl-B-D-glucosaminidase, aryl sulphatase and acid cathepsin, all showed significantly elevated activities in iris-ciliary body tissues one year after injection with the 50 microg doxorubicin. The reduction in superoxide dismutase activity may render ocular tissues susceptible to peroxidative attack and the increased activities of lysosomal hydrolases may contribute to chronic cell injury and inflammation.

    Abstract Background: Polyembolokoilamania refers to the practice of inserting foreign bodies (FBs) into natural orifices. A FB within the urethra is a relatively rare phenomenon with 646 cases recorded last year in the United Kingdom. Management of these patients presents technical challenges and complexities because of underlying psychiatric disorders that are often associated. This case illustrates a novel way of removing FBs from the genitourinary tract, requiring less resources, preventing hospital admission, and attempts to break the cycle of behavior, leading to recurrent attendance with polyembolokoilamania. Case Presentation: A 38-year-old Caucasian male prisoner, with psychiatric history presented to the emergency department (ED) with a history of inserting FBs into his urethra on 12 different occasions over a 6-week period. Of these 12 attendances, 3 resulted in admission and 2 required emergency intervention in theater under general anesthesia. After the third attendance in 5 days, it was decided to use Isiris™, a single-use flexible cystoscopy device with a built-in ureteral stent grasper, to remove the FBs and check the integrity of the urethra. The procedure was performed within the ED, without the need for admission to a ward bed or general anesthesia. Furthermore, only two members of staff were required to remove all of the urethral FBs. Conclusion: Isiris, although marketed as a stent removal device, enabled us to remove all the patient's FBs in one procedure. Isiris is an easy to use device, similar to a flexible cystoscope, that a specialist nurse or resident would be familiar using. It allows efficient and safe removal of lower urinary tract FBs, even out of hours. It requires minimal staffing support and can be done in the ED. It has the potential to reduce associated sequela of urethral polyembolokoilamania, saving resources while preserving the availability of the emergency theater. PMID:27579445

    The implantation of biomaterials induces a granulomatous reaction accompanied by foreign body giant cells (FBGCs). The characterization of multinucleated giant cells (MNGCs) around bone substitutes implanted in bone defects is more complicated because of healing with bone admixed with residual bone substitutes and their hybrid, and the appearance of two kinds of MNGCs, osteoclasts and FBGCs. Furthermore, the clinical significance of osteoclasts and FBGCs in the healing of implanted regions remains unclear. The aim of the present study was to characterize MNGCs around bone substitutes using an extraskeletal implantation model and evaluate the clinical significance of osteoclasts and FBGCs. Beta-tricalcium phosphate (β-TCP) granules were implanted into rat subcutaneous tissue with or without bone marrow mesenchymal cells (BMMCs), which include osteogenic progenitor cells. We also compared the biological significance of plasma and purified fibrin, which were used as binders for implants. Twelve weeks after implantation, osteogenesis was only detected in specimens implanted with BMMCs. The expression of two typical osteoclast markers, tartrate-resistant acid phosphatase (TRAP) and cathepsin-K (CTSK), was analyzed, and TRAP-positive and CTSK-positive osteoclasts were only detected beside bone. In contrast, most of the MNGCs in specimens without the implantation of BMMCs were FBGCs that were negative for TRAP, whereas the degradation of β-TCP was detected. In the region implanted with β-TCP granules with plasma, FBGCs tested positive for CTSK, and when β-TCP granules were implanted with purified fibrin, FBGCs tested negative for CTSK. These results showed that osteogenesis was essential to osteoclastogenesis, two kinds of FBGCs, CTSK-positive and CTSK-negative, were induced, and the expression of CTSK was plasma-dependent. In addition, the implantation of BMMCs was suggested to contribute to osteogenesis and the replacement of implanted β-TCP granules to bone. PMID

    Currently, it is not well understood how changes in biomaterial properties affect the foreign body response (FBR) or macrophage behavior. Because failed attempts at biomaterial degradation by macrophages have been linked to frustrated phagocytosis, a defining feature of the FBR, we hypothesized that increased hydrogel crosslinking density (and decreased degradability) would exacerbate the FBR. Gelatin hydrogels were crosslinked with glutaraldehyde (0.05, 0.1, and 0.3%) and implanted subcutaneously in C57BL/6 mice over the course of 3 weeks. Interestingly, changes in hydrogel crosslinking did not affect the thickness of the fibrous capsule surrounding the hydrogels, expression of the pan-macrophage marker F480, expression of three macrophage phenotype markers (iNOS, Arg1, CD163), or expression of the myofibroblast marker aSMA, determined using semi-quantitative immunohistochemical analysis. With respect to temporal changes, the level of expression of the M1 marker (iNOS) remained relatively constant throughout the study, while the M2 markers Arg1 and CD163 increased over time. Expression of these M2 markers was highly correlated with fibrous capsule thickness. Differences in spatial distribution of staining also were noted, with the strongest staining for iNOS at the hydrogel surface and increasing expression of the myofibroblast marker aSMA toward the outer edge of the fibrous capsule. These results confirm previous reports that macrophages in the FBR exhibit characteristics of both M1 and M2 phenotypes. Understanding the effects (or lack of effects) of biomaterial properties on the FBR and macrophage phenotype may aid in the rational design of biomaterials to integrate with surrounding tissue.

    Whilst levofloxacin (LVX) in combination with rifampicin (RIF) is considered the optimal treatment for prosthetic joint infection (PJI) caused by meticillin-susceptible Staphylococcus aureus (MSSA), no therapeutic alternatives have been accurately evaluated. Based on the high effectiveness of the combination of daptomycin (DAP) plus RIF against meticillin-resistant S. aureus (MRSA) in this setting, in this study the efficacy of DAP+RIF and DAP+LVX combinations was tested as alternative therapies for foreign-body infections (FBIs) caused by MSSA. A tissue-cage infection model was performed using an MSSA strain. Male Wistar rats were treated for 7 days with LVX, DAP, RIF or the combinations LVX+RIF, DAP+RIF and DAP+LVX. Antibiotic efficacy was evaluated by bacterial counts from tissue cage fluid (TCF) and the cure rate was determined from adhered bacteria. Resistance was screened. Monotherapies were less effective than combinations (P<0.05), and resistance to DAP and RIF emerged. DAP+RIF (decrease in bacterial counts in TCF, -4.9logCFU/mL; cure rate, 92%) was the most effective therapy (P<0.05). There were no differences between LVX+RIF (-3.4logCFU/mL; 11%) and DAP+LVX (-3.3logCFU/mL; 47%). No resistant strains appeared with combined therapies. In conclusion, the combinations DAP+RIF and DAP+LVX showed good efficacy and prevented resistance. DAP+RIF provided higher efficacy than LVX+RIF. These DAP combinations were efficacious alternatives therapies for MSSA FBI. Further studies should confirm whether DAP+RIF may be useful as a first-line therapy in the setting of PJI caused by MSSA.

    Ingestion of a foreign body is common among children. However, ingestion of foam earplugs (FEPs) has not been reported previously. A 7-month-old female infant presented with small bowel obstruction, which was finally proved to be a case of FEP ingestion.Computed tomography (CT) phantom study was performed to examine the imaging features of FEPs. We studied the following dry and fully wet FEPs, FEPs squeezed in pure water to varying degrees, and FEPs with different degrees of compression in the dry and wet states from day 0 to 6 and all scanned with a CT scanner.The density of a dry FEP is -843.5 ± 4.5 Hounsfield units (HU) and it increases to 0.76 ± 9.3 HU when fully wet. The densities of FEPs ranged from -844.2 to 1.0 HU with different water/air ratios, and some showed a heterogeneous geographic pattern. The densities of FEPs increase due to compression and gradual water absorption.FEPs can be potentially hazardous objects to children. Owing to the special foam structure of the FEP, it can mimic a fatty lesion if the density ranges from -100 to -50 HU; moreover, it can hide in the water if fully wet. However, it should not be mistaken as air, as the density of a dry FEP is -843.5 HU, and the contour can be observed if the window level is set appropriately. Because of its soft texture, the surgeon should be careful not to miss an FEP during the operation. Moreover, radiologists should be familiar with the CT features of FEPs so that they can be identified before surgery. PMID:27583901

    A novel biodegradable copolymer, poly(propylene fumarate-co-caprolactone) [P(PF-co-CL)], has been developed in our laboratory as an injectable scaffold for bone defect repair. In the current study, we evaluated the ability of P(PF-co-CL) to reconstitute the load-bearing capacity of vertebral bodies with lytic lesions. Forty vertebral bodies from four fresh-frozen cadaveric thoracolumbar spines were used for this study. They were randomly divided into four groups: intact vertebral body (intact control), simulated defect without treatment (negative control), defect treated with P(PF-co-CL) (copolymer group), and defect treated with poly(methyl methacrylate) (PMMA group). Simulated metastatic lytic defects were made by removing a central core of the trabecular bone in each vertebral body with an approximate volume of 25% through an access hole in the side of the vertebrae. Defects were then filled by injecting either P(PF-co-CL) or PMMA in situ crosslinkable formulations. After the spines were imaged with quantitative computerized tomography, single vertebral body segments were harvested for mechanical testing. Specimens were compressed until failure or to 25% reduction in body height and ultimate strength and elastic modulus of each specimen were then calculated from the force–displacement data. The average failure strength of the copolymer group was 1.83 times stronger than the untreated negative group and it closely matched the intact vertebral bodies (intact control). The PMMA-treated vertebrae, however, had a failure strength 1.64 times larger compared with the intact control. The elastic modulus followed the same trend. This modulus mismatch between PMMA-treated vertebrae and the host vertebrae could potentially induce a fracture cascade and degenerative changes in adjacent intervertebral discs. In contrast, P(PF-co-CL) restored the mechanical properties of the treated segments similar to the normal, intact, vertebrae. Therefore, P(PF-co-CL) may be a suitable

    Launch lock and release mechanisms constitute a common space business, however, some science missions due to very challenging functional and performance requirements need the development and testing of dedicated systems. In the LISA Pathfinder mission, a gold-coated 2-kg test mass must be injected into a nearly pure geodesic trajectory with a minimal residual velocity with respect to the spacecraft. This task is performed by the Grabbing Positioning and Release Mechanism, which has been tested on-ground to provide the required qualification. In this paper, we describe the test method that analyzes the main contributions to the mechanism performance and focuses on the critical parameters affecting the residual test mass velocity at the injection into the geodesic trajectory. The test results are also presented and discussed.

Using bioluminescent Staphylococcus aureus, we have adapted the existing foreign-body and deep-wound mouse models of staphylococcal infection to allow real-time monitoring of the bacterial colonization of catheters or tissues. This approach also enables kinetic measurements of bacterial growth and clearance in each infected animal. Persistence of infection was observed throughout the course of the study until termination of the experiment at day 16 in a deep-wound model and day 21 in the foreign-body model, providing sufficient time to test the effects of antibacterial compounds. The usefulness of both animal models was assessed by using linezolid as a test compound and comparing bioluminescent measurements to bacterial counts. In the foreign-body model, a three-dose antibiotic regimen (2, 5, and 24 h after infection) resulted in a decrease in both luminescence and bacterial counts recovered from the implant compared to those of the mock-treated infected mice. In addition, linezolid treatment prevented the formation of subcutaneous abscesses, although it did not completely resolve the infection. In the thigh model, the same treatment regimen resulted in complete resolution of the luminescent signal, which correlated with clearance of the bacteria from the thighs. PMID:12936968

    Calcium alginate dressings have beneficial effects on wound healing by providing a moist wound environment. However, cytotoxicity and the nonbiodegradable nature of calcium alginate dressings induce unresolved chronic foreign-body reaction. In this study, a novel freeze-dried alginate gel dressing (AGA-100) low in calcium ions was evaluated for cytotoxicity to L929 cells in vitro and in full-thickness pig wounds in vivo. Cytotoxicity testing on L929 cells showed the cytocompatibility of AGA-100 extracts, while extracts from Kaltostat, a well-established alginate dressing, induced cytopathic effects. In an in vivo study using pigskin, AGA-100, Kaltostat, and gauze were applied on 1-in-diameter circular full-thickness wounds on the back of pigs and the time course of wound closure was evaluated. Kaltostat and gauze dressings were used as controls. For histologic evaluation, wound tissue was harvested on day 18. AGA-100-treated wounds showed rapid wound closure compared to control wounds on day 15. Foreign-body reaction was marked in Kaltostat- and gauze-treated wounds, and differed significantly from AGA-100-treated wounds. Based on these data, AGA-100 could reduce the cytotoxicity to fibroblasts and foreign-body reaction that have been observed with currently available calcium alginate dressings; it was also found to be useful as an alginate dressing.

    In the non-industrialized countries of Africa and Asia obstetric fistulas are more frequently caused by prolonged labour, whereas in countries with developed healthcare systems they are generally the result of complications of gynaecological surgery or, rarely, benign pathologies like inflammation or foreign bodies. A 22-year-old woman was brought to the gynaecology clinic because of foul-smelling vaginal discharge. On pelvic examination a ring-like foreign body was impacted between the anterior and posterior vaginal wall. MRI scan confirmed the presence of a cylindrical foreign body in the vagina and the patient revealed that she had 'involuntarily' inserted a plastic bubble bath cap into the vagina. At surgery removal of the cap was difficult and at the end of the manoeuver evidence of a huge urethro-vesico-vaginal fistula occurred. The patient was discharged with bilateral ureteral stents and suprapubic catheter. After 3 months we performed an end-to-end anastomotic urethroplasty to repair the urethral avulsion and restored the bladder/trigonal and vaginal/cervical defects with 3 layers of sutures; 3 months later the patient had no complaints. Complex genital fistulas represent an extremely debilitating morbidity. In our case, a vaginal approach was successful, but the choice between an abdominal or vaginal approach depends on the surgeon's experience and training. PMID:25138359

    The purpose of this study was to determine if body mass index (BMI) is associated with behaviors that may increase risk for HIV and other sexually transmitted diseases (STDs) among US high school students. We analyzed nationally representative data from the 2005–2011 national Youth Risk Behavior Surveys (YRBS) to examine associations of BMI categories with sexual risk behaviors and injection drug use among sexually active high school students, using sex-stratified logistic regression models. Controlling for race/ethnicity and grade, among female and male students, both underweight (BMI < 5th percentile) and obesity (BMI ≥ 95th percentile) were associated with decreased odds of being currently sexually active (i.e., having had sexual intercourse during the past 3 months). However, among sexually active female students, obese females were more likely than normal weight females to have had 4 or more sex partners (odds ratio, OR = 1.59), not used a condom at last sexual intercourse (OR = 1.30), and injected illegal drugs (OR = 1.98). Among sexually active male students, overweight (85th percentile ≤ BMI < 95th percentile) was associated with not using a condom at last sexual intercourse (OR = 1.19) and obesity was associated with injection drug use (OR = 1.42). Among sexually active students, overweight and obesity may be indicators of increased risk for HIV and other STDs. PMID:25105024

    Antimicrobial efficacy in orthopedic device infections is diminished because of bacterial biofilms which express tolerance to antibiotics. Recently, the use of high doses of levofloxacin with rifampin has been recommended for staphylococcal infections. In the present study, we evaluated the efficacy of levofloxacin at doses of 50 mg/kg/day and 100 mg/kg/day (mimicking the usual and high human doses of 500 mg/day and 750 to 1,000 mg/day, respectively) and compared it to that of to linezolid, cloxacillin, vancomycin, and rifampin in a rat tissue cage model of experimental foreign-body infection by Staphylococcus aureus. The antimicrobial efficacy in vitro (by MIC, minimum bactericidal concentration, and kill curves) for logarithmic- and stationary-phase bacteria was compared with the in vivo efficacy. In vitro bactericidal activity at clinically relevant concentrations was reached by all drugs except rifampin and linezolid in the log-phase studies but only by levofloxacin in the stationary-phase studies. The bacterial count decreases from in vivo tissue cage fluids (means) for levofloxacin at 50 and 100 mg/kg/day, rifampin, cloxacillin, vancomycin, linezolid, and controls, respectively, were: -1.24, -2.26, -2.1, -1.56, -1.47, -1.15, and 0.33 (all groups versus controls, P < 0.05). Levofloxacin at 100 mg/kg/day (area under the concentration-time curve/MIC ratio, 234) was the most active therapy (P = 0.03 versus linezolid). Overall, in vivo efficacy was better predicted by stationary-phase studies, in which it reached a high correlation coefficient even if the rifampin group was excluded (r = 0.96; P < 0.05). Our results, including in vitro studies with nongrowing bacteria, pharmacodynamic parameters, and antimicrobial efficacy in experimental infection, provide good evidence to support the use of levofloxacin at high doses (750 to 1,000 mg/day), as recently recommended for treating patients with orthopedic prosthesis infections.

    In the present work 92 patients were studied all of whom had inhaled a foreign body (FB) into one of the tracheobronchial branch. The following factors were evaluated: sex, age, nature of the FB, localization in the respiratory tree, clinical symptoms, radiological findings, time lapse between diagnosis and removal. The peak incidence (61.9%) was in children under 3 years of age with a male-female ratio of 2:1. The most frequently inhaled FBs were of organic nature (31.5%); of these 58.6% were peanuts. The time lapse between inhalation and removal of the FB was as follows: in 20.5% the object was removed within 24 hours; in 66.4% within one week; in 12% in more than a week; and in 1.1% it took more than 8 weeks. In 53.2% of the cases the right bronchial branches were involved while in 28.2% the left side was affected. The most frequent symptoms were coughing (73.9%), wheezing (69.5%), dyspnea (51%) and fever (17.3%). Radiography detected the FB in only 7 cases (8.7%); in the remaining cases only indirect signs of the FB could be found: atelectasia (11.9%), emphysema (19.5%), cardio-mediastinic shift controlateral to the FB (10.8%). As regards complications, only 6 patients showed signs of slight endobronchial bleeding, 2 cases showed a pneumothorax and one other patient required a tracheotomy because of the particular shape of the FB which proved unable to pass backward through the glottis. In all cases the FB was removed using stiff bronchoscopy under either local or general anesthesia. The authors feel that, even if no clinical signs are found and radiography proves negative, one must always consider the possibility of a FB in the tracheal-bronchial branches, particularly in patients within the age range most at risk (under 3 years) and in those having a highly suspicious clinical history. In addition, the authors assert that the use of corticosteroids before and after the bronchoscopy markedly decreases the incidence of post-operative subglottic edema which

    Nano-silicon dioxide (SiO2) is used nowadays in several biomedical applications such as drug delivery and cancer therapy, and is produced on an industrial scale as additive to paints and coatings, cosmetics and food. Data regarding the long-term biokinetics of SiO2 engineered nanoparticles (ENPs) is lacking. In this study, the whole-body biodistribution of SiO2 core-shell ENPs containing a paramagnetic core of Fe3O4 was investigated after a single exposure via intravenous injection or intratracheal instillation in mice. The distribution and accumulation in different organs was evaluated for a period of 84 days using several techniques, including magnetic resonance imaging, inductively coupled plasma mass spectrometry, X-ray fluorescence and X-ray absorption near edge structure spectroscopy. We demonstrated that intravenously administered SiO2 ENPs mainly accumulate in the liver, and are retained in this tissue for over 84 days. After intratracheal instillation, an almost complete particle clearance from the lung was seen after 84 days with distribution to spleen and kidney. Furthermore, we have strong evidence that the ENPs retain their original core-shell structure during the whole observation period. This work gives an insight into the whole-body biodistribution of SiO2 ENPs and will provide guidance for further toxicity studies. PMID:26525175

    Conclusion The intraoperative application of glucocorticoid-loaded hydrogels seems to cause a reduction in neutrophil infiltration. No beneficial effect on hearing thresholds was detected. Objectives To evaluate the application of dexamethasone- and triamcinolone-acetonide- loaded hydrogels for effects on hearing-preservation and foreign-body reaction in a guinea pig model for cochlear implantation. Methods 48 guinea pigs (n= 12/group) were implanted with a single channel electrode and intraoperatively treated with 50 µl of a 20% w/v poloxamer 407 hydrogel loaded with 6% dexamethasone or 30% triamcinolone-acetonide, a control hydrogel, or physiological saline. Click- and tone burst-evoked compound action potential thresholds were determined pre- and directly postoperatively as well as on days 3, 7, 14, 21 and 28. At the end of the experiment, temporal bones prepared for histological evaluation by a grinding/polishing technique with the electrode in situ. Three ears per treatment group were serially sectioned and evaluated for histological alterations. Results The intratympanic application of glucocorticoid-loaded hydrogels did not improve the preservation of residual hearing in this cochlear implant model. The foreign body reaction to the electrode appeared reduced in the glucocorticoid treated animals. No correlation was found between the histologically described trauma to the inner ear and the resulting hearing threshold-shifts. PMID:25720453

    The prophylactic and therapeutic activities of two fluoroquinolones, levofloxacin and alatrofloxacin (the l-Ala-l-Ala prodrug of trovafloxacin), were compared to those of vancomycin in two different experimental models of foreign-body-associated infections caused by methicillin-resistant but quinolone-susceptible Staphylococcus aureus (MRSA) isolates. In a guinea pig model of prophylaxis, subcutaneously implanted tissue cages were infected with 103 CFU of MRSA, which was a 100% infectious dose in control animals. A single dose of 50 mg of levofloxacin per kg of body weight, administered intraperitoneally 3 h before bacterial challenge, was more efficient than vancomycin for the prevention of infections in tissue cages with MRSA inocula of 104 and 105 CFU. In a rat model used to evaluate therapy of chronic tissue cage infection caused by MRSA, the efficacies of 7-day high-dose regimens of levofloxacin (100 mg/kg once a day [q.d.] or 50 mg/kg twice a day [b.i.d.]) or alatrofloxacin (50 mg/kg q.d.) were compared to the efficacy of vancomycin (50 mg/kg b.i.d.). Active levels of levofloxacin, trovafloxacin, and vancomycin were continuously present in tissue cage fluid, with the levels exceeding the minimal bactericidal concentrations for MRSA during therapy. The q.d. and b.i.d. regimens of levofloxacin had equivalent activities and were significantly (P < 0.05) more active than alatrofloxacin or vancomycin in decreasing the viable counts of MRSA in tissue cage fluids. No quinolone-resistant mutants emerged during therapy with either fluoroquinolone. The mechanisms explaining the inferior activity of alatrofloxacin compared to the activity of levofloxacin against chronic foreign-body-associated infections by MRSA are unknown. PMID:11959588

    The prophylactic and therapeutic activities of three broad-spectrum fluoroquinolones were evaluated in two different experimental models of foreign-body infections caused by methicillin-resistant Staphylococcus aureus (MRSA) susceptible to quinolones. In a guinea pig model of prophylaxis, subcutaneously implanted tissue cages were infected at a > 90% rate by 10(2) CFU of MRSA in control animals. A single dose of 50 mg of ciprofloxacin per kg of body weight administered intraperitoneally 3 h before bacterial challenge was less effective than an equivalent regimen of either sparfloxacin or temafloxacin in decreasing the rate of experimental infection in tissue cages challenged with increasing inocula of MRSA. In a rat model evaluating the therapy of chronic tissue cage infection caused by MRSA, the efficacy of a 7-day high-dose (50-mg/kg twice-daily) regimen of sparfloxacin, temafloxacin, or ciprofloxacin was compared to that of vancomycin (50 mg/kg twice daily). Active levels of sparfloxacin, temfloxacin, or ciprofloxacin were continuously present in tissue cage fluid during therapy, exceeding their MBCs for MRSA by 6- to 20-fold. Either temafloxacin, sparfloxacin, or vancomycin was significantly (P < 0.01) more active than ciprofloxacin in decreasing the viable counts of MRSA in tissue cage fluids. The different activities of ciprofloxacin compared with those of the other two quinolones against chronic tissue cage infections caused by MRSA did not involve the selective emergence of quinolone-resistant mutants. Temafloxacin and ciprofloxacin, which showed the most prominent differences in their in vivo activities, however, exhibited similar bactericidal properties and pharmacokinetic parameters in the rat model. In conclusion, both temafloxacin and sparfloxacin were significantly more active than ciprofloxacin for the prophylaxis or treatment of experimental foreign-body infections caused by a quinolone-susceptible strain of MRSA.

  1. Reducing surface area while maintaining implant penetrating profile lowers the brain foreign body response to chronically implanted planar silicon microelectrode arrays.

    A consistent feature of the foreign body response (FBR), irrespective of the type of implant, is persistent inflammation at the biotic-abiotic interface signaled by biomarkers of macrophage/microglial activation. Since macrophage-secreted factors shape the foreign body reaction, implant designs that reduce macrophage activation should improve biocompatibility and, with regard to recording devices, should improve reliability and longevity. At present, it is unclear whether the goal of seamless integration is possible or whether electrode developers can modulate specific aspects of the FBR by intentionally manipulating the constitutive properties of the implant. To explore this area, we studied the chronic brain FBR to planar solid silicon microelectrode arrays and planar lattice arrays with identical penetrating profiles but with reduced surface area in rats after an 8-week indwelling period. Using quantitative immunohistochemistry, we found that presenting less surface area after equivalent iatrogenic injury is accompanied by significantly less persistent macrophage activation, decreased blood brain barrier leakiness, and reduced neuronal cell loss. Our findings show that it is possible for implant developers to modulate specific aspects of the FBR by intentionally manipulating the constitutive properties of the implant. Our results also support the theory that the FBR to implanted electrode arrays, and likely other implants, can be explained by the presence of macrophages at the biotic-abiotic interface, which act as a sustained delivery source of bioactive agents that diffuse into the adjacent tissue and shape various features of the brain FBR. Further, our findings suggest that one method to improve the recording consistency and lifetime of implanted microelectrode arrays is to design implants that reduce the amount of macrophage activation at the biotic-abiotic interface and/or enhance the clearance or impact of their released factors.

  2. The introduction of automated dispensing and injection during PET procedures: a step in the optimisation of extremity doses and whole-body doses of nuclear medicine staff.

    Significant staff exposure is generally expected during PET-and PET/CT applications. Whole-body doses as well as extremity doses are usually higher per procedure compared with SPECT applications. Dispensing individual patient doses and manual injection involves high extremity doses even when heavy weighted syringe shields are used. In some cases the external radiation causes an exposure to the fingertips of more than 500 mSv y(-1), which is the yearly limit. Whole-body doses per procedure are relatively lower compared with extremity doses and are generally spread over the entire procedure (Guillet, B., Quentin, P., Waultier, S., Bourrelly, M., Pisano, P. and Mundler, O. Technologist radiation exposure in routine clinical practice with 18F-FDG PET. J. Nucl. Med. Technol. 33, 175-179 (2005). Optimisation of the individual workload is often used to restrict staff doses, but many PET centres face the need for further optimisation to reduce the staff doses to an acceptable level. During this study the effect of the use of an automated dispensing and injection system for (18)FDG on whole-body doses and extremity doses was evaluated. Detailed dosimetric studies using thermoluminescent and direct ion storage dosimetry were carried out before and after the introduction of this system. The results show that the extremity doses can be reduced by more than 95 % up to a mean level of 10 muSv per handled GBq. At the same time, whole-body doses can be halved during injection of the tracer. This results in a dose reduction of 20 % during the entire procedure of injection, escorting and positioning. In this way, the study shows that with the use of automated dispensing and injection a considerable staff dose reduction can be obtained. PMID:20335185

    Interleukin-1β (IL-1β) appears to be the mediator of the reciprocal communication between the brain and the immune system. IL-1β has been shown to modulate homeostatic functions including fever, feeding, drinking and cardiovascular control. The aim of the present study was to investigate the effects of IL-1β injections directly into the subfornical organ (SFO) and the median preoptic nucleus (MnPO) on salt appetite, hedonic response, locomotion, body temperature and blood pressure in sodium-depleted rats. IL-1β injections into the SFO and MnPO at the doses of 0.2, 0.4, 0.8 and 1.6ng/0.2μl promoted a dose-dependent inhibition of salt intake in sodium-depleted rats. Results of the "dessert" test and the "open field" test suggested that the inhibition of salt appetite is not due to any changes in the hedonic aspect of ingestive behavior or to changes in locomotor activity. As expected, IL-1β injections into the SFO and MnPO promoted an increase in body temperature. However, the fever induced by IL-1β injected into the SFO was slower than the increase in body temperature obtained following IL-1β injection into the MnPO. Furthermore, IL-1β at a dose of 1.6ng/0.2μl directly injected into the MnPO led to a significant increase in blood pressure, while injection of the same concentration of IL-1β into the SFO caused no significant change in blood pressure or heart rate. The action of pro-inflammatory cytokines may interfere with the normal control of body temperature, blood pressure and fluid homeostasis, producing the adjustment required to cope with infection and inflammation. Further studies are required to clarify the mechanisms involved in fever, blood pressure increase and inhibition of sodium appetite induced by injections of IL-1β into the SFO and MnPO in sodium-depleted rats.

    Severe bradycardia is a common untoward effect during balloon angioplasty when performing carotid artery stenting. Therefore atropine injection even before dilatation and the presence of an anesthesiologist are advocated in all patients. In the surgical literature, injection of a local anesthetic agent into the carotid sinus before carotid endarterectomy was performed in an attempt to ameliorate perioperative hemodynamic instability. This study was undertaken to test the hypothesis that percutaneous infiltration of the carotid sinus with local anesthetic immediately before balloon dilatation reduces bradycardia and ameliorates the need for atropine injection or the presence of an anesthesiologist. Infiltration of the carotid sinus with 5 ml of 1% lidocaine, 3 min before dilatation, was performed in 30 consecutive patients. No one exhibited any significant rhythm change that required atropine injection. The anesthesiologist did not face any hemodynamic instability during the carotid artery stenting procedure.

    Background Post-sternotomy mediastinitis (PSM) is a devastating surgical complication affecting 1–3% of patients that undergo cardiac surgery. Staphylococcus aureus is one of the most commonly encountered bacterial pathogen cultured from mediastinal samples obtained from patients with PSM. A component of the membrane of the gram positive bacteria, lipoteichoic acid, stimulates the blood monocytes and macrophages to secrete cytokines, radicals and nitrogen species leading to oxido-inflammatory damage. This seems to be responsible for the high mortality rate in PSM. For the evaluation of the pathogenesis of infection or for the investigation of alternative treatment models in infection, no standard model of mediastinitis seems to be available. In this study, we evaluated four mediastinitis models in rats. Methods The rats were divided into four groups to form different infection models. Group A: A suspension of 1 × 107 colony-forming units Staphylococcus aureus in 0,5 mL was inoculated from the right second intercostal space into the mediastinum. Group B: A hole was created in the right second intercostal space and a piece of stainless-steel implant with a length of 0.5 cm was inserted into the mediastinum and a suspension of 1 × 107 cfu bacteria in 0,5 mL was administered via the tail vein. Group C: Precolonized stainless-steel implant was inserted into the mediastinum. Group D: Precolonized stainless-steel implant was inserted into the mediastinum and the bacteria suspension was also injected into the mediastinum. On the 10th day, rats were sacrificed and the extension of infection in the mediastenae was evaluated by quantitative cultures. Myeloperoxidase activity (MPO) and malondialdehyde (MDA) levels were determined in the sera to evaluate the neutrophil activation and assess the inflammatory oxidation. Results The degree of infection in group C and D were 83.3% and 100% respectively (P < 0.001). MDA levels were significantly higher in these two groups than

    A 34-year-old patient presented with a right orbito-facial mass since childhood, consistent with a congenital arteriovenous (AV) malformation. Prior to presentation, she had multiple incomplete surgical resections and embolizations with N-butyl acetyl acrylate and Onyx-18. The patient reported gradual, progressive vision loss shortly after Onyx-18 embolization. Five months after embolization, she presented with decreased vision, disfigurement and mechanical ptosis relating to a large subcutaneous mass affecting the medial right upper eyelid and forehead. Significant exam findings included a visual acuity of 20/400 (20/60 prior to embolization), an afferent pupillary defect, and optic disc pallor. MRI and angiography revealed a persistent AV malformation with feeders from the ophthalmic artery and an absent choroidal flush to the right eye. Pathology from surgical resection showed a significant foreign body giant cell reaction to the embolization material adjacent to the vessels. We suggest that an incomplete embolization with Onyx-18 may have caused vascular steal syndrome from the ophthalmic artery. PMID:27239463

    The importance of biomechanics in glucose sensor function has been largely overlooked. This article is the first part of a two-part review in which we look beyond commonly recognized chemical biocompatibility to explore the biomechanics of the sensor–tissue interface as an important aspect of continuous glucose sensor biocompatibility. Part I provides a theoretical framework to describe how biomechanical factors such as motion and pressure (typically micromotion and micropressure) give rise to interfacial stresses, which affect tissue physiology around a sensor and, in turn, impact sensor performance. Three main contributors to sensor motion and pressure are explored: applied forces, sensor design, and subject/patient considerations. We describe how acute forces can temporarily impact sensor signal and how chronic forces can alter the foreign body response and inflammation around an implanted sensor, and thus impact sensor performance. The importance of sensor design (e.g., size, shape, modulus, texture) and specific implant location on the tissue response are also explored. In Part II: Examples and Application (a sister publication), examples from the literature are reviewed, and the application of biomechanical concepts to sensor design are described. We believe that adding biomechanical strategies to the arsenal of material compositions, surface modifications, drug elution, and other chemical strategies will lead to improvements in sensor biocompatibility and performance.

    Formation of foreign body giant cells (FBGCs) occurs following implantation of medical devices such as artificial joints and is implicated in implant failure associated with inflammation or microbial infection. Two major macrophage subpopulations, M1 and M2, play different roles in inflammation and wound healing, respectively. Therefore, M1/M2 polarization is crucial for the development of various inflammation-related diseases. Here, we show that FBGCs do not resorb bone but rather express M2 macrophage-like wound healing and inflammation-terminating molecules in vitro. We also found that FBGC formation was significantly inhibited by inflammatory cytokines or infection mimetics in vitro. Interleukin-1 receptor-associated kinase-4 (IRAK4) deficiency did not alter osteoclast formation in vitro, and IRAK4-deficient mice showed normal bone mineral density in vivo. However, IRAK4-deficient mice were protected from excessive osteoclastogenesis induced by IL-1β in vitro or by LPS, an infection mimetic of Gram-negative bacteria, in vivo. Furthermore, IRAK4 deficiency restored FBGC formation and expression of M2 macrophage markers inhibited by inflammatory cytokines in vitro or by LPS in vivo. Our results demonstrate that osteoclasts and FBGCs are reciprocally regulated and identify IRAK4 as a potential therapeutic target to inhibit stimulated osteoclastogenesis and rescue inhibited FBGC formation under inflammatory and infectious conditions without altering physiological bone resorption.

    Limited antimicrobial agents are available for the treatment of implant-associated infections caused by fluoroquinolone-resistant Gram-negative bacilli. We compared the activities of fosfomycin, tigecycline, colistin, and gentamicin (alone and in combination) against a CTX-M15-producing strain of Escherichia coli (Bj HDE-1) in vitro and in a foreign-body infection model. The MIC and the minimal bactericidal concentration in logarithmic phase (MBClog) and stationary phase (MBCstat) were 0.12, 0.12, and 8 μg/ml for fosfomycin, 0.25, 32, and 32 μg/ml for tigecycline, 0.25, 0.5, and 2 μg/ml for colistin, and 2, 8, and 16 μg/ml for gentamicin, respectively. In time-kill studies, colistin showed concentration-dependent activity, but regrowth occurred after 24 h. Fosfomycin demonstrated rapid bactericidal activity at the MIC, and no regrowth occurred. Synergistic activity between fosfomycin and colistin in vitro was observed, with no detectable bacterial counts after 6 h. In animal studies, fosfomycin reduced planktonic counts by 4 log10 CFU/ml, whereas in combination with colistin, tigecycline, or gentamicin, it reduced counts by >6 log10 CFU/ml. Fosfomycin was the only single agent which was able to eradicate E. coli biofilms (cure rate, 17% of implanted, infected cages). In combination, colistin plus tigecycline (50%) and fosfomycin plus gentamicin (42%) cured significantly more infected cages than colistin plus gentamicin (33%) or fosfomycin plus tigecycline (25%) (P < 0.05). The combination of fosfomycin plus colistin showed the highest cure rate (67%), which was significantly better than that of fosfomycin alone (P < 0.05). In conclusion, the combination of fosfomycin plus colistin is a promising treatment option for implant-associated infections caused by fluoroquinolone-resistant Gram-negative bacilli. PMID:23295934

    Enterococcus faecalis can cause healthcare-associated biofilm infections, including those of orthopedic devices. Treatment of enterococcal prosthetic joint infection is difficult, in part, due to biofilm-associated antimicrobial resistance. We previously showed that the E. faecalis OG1RF genes ahrC and eep are in vitro biofilm determinants and virulence factors in animal models of endocarditis and catheter-associated urinary tract infection. In this study, we evaluated the role of these genes in a rat acute foreign body osteomyelitis model and in in vitro biofilm-associated antimicrobial resistance. Osteomyelitis was established for one week following the implantation of stainless steel orthopedic wires inoculated with E. faecalis strains OG1RF, ΩahrC, and ∆eep into the proximal tibiae of rats. The median bacterial loads recovered from bones and wires did not differ significantly between the strains at multiple inoculum concentrations. We hypothesize that factors present at the infection site that affect biofilm formation, such as the presence or absence of shear force, may account for the differences in attenuation in the various animal models we have used to study the ΩahrC and ∆eep strains. No differences among the three strains were observed in the planktonic and biofilm antimicrobial susceptibilities to ampicillin, vancomycin, daptomycin, linezolid, and tetracycline. These findings suggest that neither ahrC nor eep directly contribute to E. faecalis biofilm-associated antimicrobial resistance. Notably, the experimental evidence that the biofilm attachment mutant ΩahrC displays biofilm-associated antimicrobial resistance suggests that surface colonization alone is sufficient for E. faecalis cells to acquire the biofilm antimicrobial resistance phenotype.

    Matrix metalloproteinases (MMPs) are enzymes with specificity towards extracellular matrix (ECM) components. MMPs, especially MMP-9, have been shown to degrade components of the basal lamina and disrupt the blood-brain barrier (BBB) and thus, contribute to neuroinflammation. In the present study we examined the role of MMP-9 in the foreign body response in the brain. Millipore filters of mixed cellulose ester were implanted into the brain cortex of wild type and MMP-9 -null mice for a period of 2 d to 8 wks and the response was analyzed by histology and immunohistochemistry. We observed enhanced and prolonged neuroinflammation in MMP-9-null mice, evidenced by persistence of neutrophils, macrophages/microglia, and reactive astrocytes up to 8 wks post-implantation. In addition, blood vessel density around implants was increased in MMP-9-null mice and detection of mouse serum albumin (MSA) indicated that vessels were leaky. Immunohistochemical and western blot analyses indicated that this defect was associated with the absence of tight junction proteins zonula occludens-1 (ZO-1) and ZO-2 from vessels in proximity to implants. Analysis of brain sections and brain protein extracts revealed that the levels of the pro-inflammatory cytokine interleukin-1β (IL-1β), which is a substrate for MMP-9, were significantly higher in MMP-9-null mice at 8wks post-implantation. Collectively, our studies suggest that increased levels of IL-1β and the delayed repair of BBB are associated with prolongation of the FBR in MMP-9-null mice. PMID:19264129

    Foreign body reaction induced by biomaterials is a serious problem in clinical applications. Although 317L-Cu stainless steel (317L-Cu SS) is a new type of implant material with antibacterial ability and osteogenic property, the foreign body reaction level still needs to be assessed due to its Cu2+ releasing property. For this purpose, two macrophage cell lines were selected to detect cellular proliferation, apoptosis, mobility, and the secretions of inflammatory cytokines with the influence of 317L-Cu SS. Our results indicated that 317L-Cu SS had no obvious effect on the proliferation and apoptosis of macrophages; however, it significantly increased cellular migration and TNF-α secretion. Then, C57 mice were used to assess foreign body reaction induced by 317L-Cu SS. We observed significantly enhanced recruitment of inflammatory cells (primarily macrophages) with increased TNF-α secretion and apoptosis level in tissues around the materials in the early stage of implantation. With tissue healing, both inflammation and apoptosis significantly decreased. Further, we discovered that NF-κB pathway and Caspase 3 played important roles in 317L-Cu SS induced inflammation and apoptosis. We concluded that 317L-Cu SS could briefly promote the inflammation and apoptosis of surrounding tissues by regulating the activity of NF-κB pathway and Caspase 3. All these discoveries demonstrated that 317L-Cu SS has a great potential for clinical application. PMID:26604748

    The present study aims to report a case of conjunctival necrosis and scleritis due to a subtenon injection of triamcinolone acetonate. A 15-year-old boy received a subtenon injection of triamcinolone acetonate after a pars plana vitrectomy due to an intraocular foreign body. Seven days later, conjunctival necrosis and scleritis appeared at the site of injection. No improvement was seen after seven days of conservative treatment, and necrotic tissue debridement was performed. Within one week the conjunctiva cleared. Conjunctival necrosis and scleritis are rare complications of periocular corticosteroid injections, but an early diagnosis can be very valuable. Improper dosage and injection site of corticosteroids with insufficient prophylactic antibiotics are predisposing factors. If conservative treatment is not sufficient, debridement should be considered as a potential critical treatment option. PMID:24396585

    Jet ventilation initially described by Sanders has been modified and improved for use with the Storz bronchoscope. Theoretical and technical performance are discussed and the mechanical and physiological properties are dealt with e.g. FiO2, driving and endotracheal pressure, expiratory CO2 concentrations, blood gas analysis, pulmonary artery pressure and electrocardiographic changes. Using this method prolonged diagnostic and surgical procedures, such as cauterisation of bronchial adenoma, removal of foreign bodies from the airways especially of small children and bronchial toilet in status asthmaticus, are rendered free from problems for the anaesthetist. We believe that the inject ventilator is a very useful addition to endotracheal surgery. PMID:495920

    Hematopoietic injury is the most common side effect of radiotherapy. However, the methods available for the mitigating of radiation injury remain limited. Xuebijing injection (XBJ) is a traditional Chinese medicine used to treat sepsis in the clinic. In this study, we investigated the effects of XBJ on the survival rate in mice with hematopoietic injury induced by γ ray ionizing radiation (IR). Mice were intraperitoneally injected with XBJ daily for seven days after total body irradiation (TBI). Our results showed that XBJ (0.4 mL/kg) significantly increased 30-day survival rates in mice exposed to 7.5 Gy TBI. This effect may be attributable to improved preservation of white blood cells (WBCs) and hematopoietic cells, given that bone marrow (BM) cells from XBJ-treated mice produced more granulocyte-macrophage colony forming units (CFU-GM) than that in the 2 Gy/TBI group. XBJ also decreased the levels of reactive oxygen species (ROS) by increasing glutathione (GSH) and superoxide dismutase (SOD) levels in serum and attenuated the increased BM cell apoptosis caused by 2 Gy/TBI. In conclusion, these findings suggest that XBJ enhances the survival rate of irradiated mice and attenuates the effects of radiation on hematopoietic injury by decreasing ROS production in BM cells, indicating that XBJ may be a promising therapeutic candidate for reducing hematopoietic radiation injury.

    A 72-year-old Taiwanese woman had the history of cosmetic cryopreserved autologous fat injection on her forehead ~21 years ago and was referred to our oculoplastic clinic and presented with multiple painless mass, which she had for 4 years, on both upper eyelids. Histopathology confirmed the diagnosis of foreign body granuloma on both upper eyelids. Clinicians should be aware of the potential complication of granuloma reaction and migration even many years after the injection. We advise that autologous fat injection should be performed solely by trained physicians and it should be made known that there is a possible occurrence of migration. PMID:27382336

    Facial changes with aging include thinning of the epidermis, loss of skin elasticity, atrophy of muscle, and subcutaneous fat and bony changes, all which result in a loss of volume. As temporal bones become more concave, and the temporalis atrophies and the temporal fat pad decreases, volume loss leads to an undesirable, gaunt appearance. By altering the temporal fossa and upper face with hyaluronic acid filler, those whose specialty is injecting filler can achieve a balanced and more youthful facial structure. Many techniques have been described to inject filler into the fossa including a "fanned" pattern of injections, highly diluted filler injection, and the method we describe using a three-injection approach. Complications of filler in the temporal fossa include bruising, tenderness, swelling, Tyndall effect, overcorrection, and chewing discomfort. Although rare, more serious complications include infection, foreign body granuloma, intravascular necrosis, and blindness due to embolization into the ophthalmic artery. Using reversible hyaluronic acid fillers, hyaluronidase can be used to relieve any discomfort felt by the patient. Injectors must be aware of the complications that may occur and provide treatment readily to avoid morbidities associated with filler injection into this sensitive area. PMID:26311237

    Although exact statistics are lacking, body modifications for cosmetic purposes are performed in many countries. The commonest forms include tattooing, body piercing, and breast and facial augmentation using implants or injectable fillers. Liposuction and, to a lesser extent, mesotherapy are also practiced in many countries. Infective complications of these procedures include local infections, transmission of bloodborne pathogens (viral hepatitis and human immunodeficiency virus), and distant infections such as infective endocarditis. Presence of foreign bodies, long healing time of piercing wounds, and poor compliance with infection control practices of some practitioners all predispose the recipients to infections. Apart from the endogenous microbial flora of the skin and mucosae, atypical mycobacteria, especially the rapid growers, have emerged as some of the most important pathogens in such settings. Outbreaks of infection are commonly reported. We hereby review the current knowledge of the topic with specific focus on infections associated with tattooing, body piercing, breast augmentation, mesotherapy, liposuction, and tissue filler injections. Greater awareness among consumers and health-care professionals, as well as more stringent regulations by the health authorities, is essential to minimize the health risks arising from these procedures.

    An injection nozzle having a main body portion with an outer peripheral wall is disclosed. The nozzle includes a plurality of fuel/air mixing tubes disposed within the main body portion and a fuel flow passage fluidly connected to the plurality of fuel/air mixing tubes. Fuel and air are partially premixed inside the plurality of the tubes. A second body portion, having an outer peripheral wall extending between a first end and an opposite second end, is connected to the main body portion. The partially premixed fuel and air mixture from the first body portion gets further mixed inside the second body portion. The second body portion converges from the first end toward said second end. The second body portion also includes cooling passages that extend along all the walls around the second body to provide thermal damage resistance for occasional flame flash back into the second body.

  2. Imaging features of midface injectable fillers and associated complications.

    2013-08-01

    Injectable fillers are increasingly used for midface augmentation, which can be performed for facial rejuvenation and treatment of HIV facial lipoatrophy. A variety of temporary and permanent filler agents has been developed, including calcium hydroxylapatite, collagen, liquid silicone, polytetrafluoroethylene, hyaluronic acid, poly-l-lactic acid, and polyacrylamide gel. Facial fillers are sometimes encountered on radiologic imaging incidentally and should not be mistaken for pathology. Alternatively, patients with facial fillers may undergo imaging specifically to evaluate associated complications, such as infection, overfilling, migration, foreign-body reaction, and scarring. Therefore, it is important to be familiar with the imaging appearances of the various filler materials and their complications. PMID:22837310

    We compared the efficacies of daptomycin (doses equivalent to 8 to 10 mg/kg of body weight/day in humans) and cloxacillin alone with those of cloxacillin-rifampin and cloxacillin-daptomycin combinations, using a tissue cage methicillin-susceptible Staphylococcus aureus (MSSA) infection model. Monotherapies were less effective than combinations (P<0.05), and daptomycin resistance emerged. Cloxacillin-daptomycin proved as effective as cloxacillin-rifampin and prevented the appearance of resistance; this combination may be an alternative anti-MSSA therapy, which may offer greater benefits in the early treatment of prosthetic joint infections (PJI).

  5. Effects on body temperature of prostaglandins of the A, E and F series on injection into the third ventricle of unanaesthetized cats and rabbits.

    1. Prostaglandins were injected into the third ventricle of unanaesthetized cats and rabbits whilst rectal temperature was recorded.2. In cats prostaglandin E(1) and E(2) (PGE(1) and PGE(2)) produced hyperthermia which mostly began within a minute of injection and lasted 1 or more hours. With PGE(1) the hyperthermia was shown to be dose dependent between 10 ng and 10 mug (2.8 x 10(-11) and 2.8 x 10(-8)M). The hyperthermia was associated with vigorous shivering, skin vasoconstriction and piloerection. In several experiments a secondary rise in temperature occurred a few hours after the injection but such an effect was sometimes observed with control injections of 0.9% NaCl solution as well.3. None of the other prostaglandins (A(1), F(1alpha), F(2alpha)) examined in cats had an immediate or strong effect on temperature comparable to the hyperthermia produced by PGE(1) and PGE(2).4. In rabbits PGE(1) (2 mug) also caused hyperthermia which began shortly after the injection and lasted for hours. PGF(2alpha) and PGA(1), did not affect temperature.5. In cats it was seen that an intraperitoneal injection of 4-acetamidophenol (paracetamol 50 mg/kg) did not affect the initial strong hyperthermia produced by PGE(1) and PGE(2) but abolished the secondary rise.6. The possibility is discussed that PGE(1) plays a role as a central transmitter or modulator in temperature regulation. PMID:4330929

    Reproducing extracellular matrix topographical cues, such as those present within acellular dermal matrix (ADM), in synthetic implant surfaces, may augment cellular responses, independent of surface chemistry. This could lead to enhanced implant integration and performance while reducing complications. In this work, the hierarchical micro and nanoscale features of ADM were accurately and reproducibly replicated in polydimethylsiloxane (PDMS), using an innovative maskless 3D grayscale fabrication process not previously reported. Human breast derived fibroblasts (n=5) were cultured on PDMS surfaces and compared to commercially available smooth and textured silicone implant surfaces, for up to one week. Cell attachment, proliferation and cytotoxicity, in addition to immunofluorescence staining, SEM imaging, qRT-PCR and cytokine array were performed. ADM PDMS surfaces promoted cell adhesion, proliferation and survival (p=<0.05), in addition to increased focal contact formation and spread fibroblast morphology when compared to commercially available implant surfaces. PCNA, vinculin and collagen 1 were up-regulated in fibroblasts on biomimetic surfaces while IL8, TNFα, TGFβ1 and HSP60 were down-regulated (p=<0.05). A reduced inflammatory cytokine response was also observed (p=<0.05). This study represents a novel approach to the development of functionalised biomimetic prosthetic implant surfaces which were demonstrated to significantly attenuate the acute in vitro foreign body reaction to silicone.

  10. Delayed granulomatous reactions to facial cosmetic injections of polymethylmethacrylate microspheres and liquid injectable silicone: A case series.

    Polymethylmethacrylate microsphere (PMMA) and liquid injectable silicone (LIS) fillers are non-biodegradable, synthetic polymers utilized for long-term soft-tissue augmentation. Delayed granulomatous reactions to permanent fillers are a rare yet significant event that can occur months to years post procedure and are often refractory to treatment and associated with significant cosmetic morbidity. We report a case series of 4 patients who developed granulomatous reactions to PMMA or LIS, 15 months to 5 years post injection. The etiology of granulomatous reactions to permanent fillers is still poorly understood, with foreign-body reactions and/or biofilms purported to play a role. Real-time biochemical analysis with polymerase chain reaction should be performed when the index of suspicion for the presence of a biofilm is high. PMID:26735450

    Objective To determine changes in body weight and composition resulting from hormonal contraception. Study design Dual-energy X-ray absorptiometry was performed at baseline and every 6 months for 3 years on 703 women (200 Black, 247 White, 256 Hispanic) initiating use of oral contraception (OC, n = 245), depot medroxyprogesterone acetate (DMPA, n = 240), or nonhormonal contraception (NH, n = 218). DMPA discontinuers were followed for up to 2 years to examine the reversibility of observed changes. Results Over 36 months, DMPA users increased their weight (+5.1 kg), body fat (+4.1 kg), percent body fat (+3.4%), and central-to-peripheral fat ratio (+0.1) more than OC and NH users (P<.01). OC use did not cause weight gain. After DMPA discontinuation, NH users lost 0.42 kg/6 months while OC users gained 0.43 kg/6 months. Conclusions Body weight and fat significantly increase while using DMPA. After discontinuation, some decrease occurs when NH is used. PMID:19254592
