    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.

    New methods are constantly introduced for soft tissue augmentation to correction of scars and wrinkles. Each method has its advantages and disadvantages. A 48 year old woman developed visible and palpable plaques and papules after treatment of the nasolabial and glabella folds with a poly L-lactic acid implant. Histological examination revealed a foreign body granuloma, while electron microscopy showed remnants of the implant material, demonstrating that poly L-lactic acid can also induce a foreign body reaction.

  4. [Foreign Body in Esophagus].

    PubMed

    Domeki, Yasushi; Kato, Hiroyuki

    2015-07-01

    An esophageal foreign body is the term for a foreign body in the esophagus. The 2 age groups most prone to this condition are children age 9 and under (and especially toddlers age 4 and under) and elderly individuals age 70 and over. A foreign body often lodges where the esophagus is most constricted. In toddlers, the foreign body is often currency or coins or a toy. In adults, the body is often a piece of fish, dentures, a piece of meat, a pin or needle, or a drug in its blister pack packaging. In children, an esophageal foreign body is treated by fluoroscopically guided removal of the body with a balloon catheter or magnetic catheter or removal of the body via endoscopy or direct esophagoscopy under general anesthesia. In adults, the best choice for treating an esophageal foreign body is removing the body with an endoscope but there are instances where surgery is performed because the body is hard to remove endoscopically, a puncture has occurred, or empyema or mediastinitis has developed. This paper reviews the diagnosis and treatment of an esophageal foreign body.

    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

    PubMed

    2014-03-01

    The ingestion of foreign bodies is one of the most important and difficult emergencies for a physician to diagnose. Accidental ingestion is more common in children, in patients with dental implants, in individuals with mental disability and in drug users. Voluntary ingestion is found in patients who are psychologically unstable, in prisoners or those who attempt suicide. Foreign bodies may be divided into food as fish bones, chicken bones, food bolus, meat, etc. or real foreign bodies such as orthodontic implants, needles, pins, glass, coins, etc. The authors present a case of management, from the medicolegal point of view, of a female patient age 80, who complained, for some weeks of modest pain in the left iliac fossa, and afterwards the endoscopy showed a toothpick into the wall of the sigmoid colon. Assessed of the clinical status of the patient presented severe cardiac comorbidities so that before processing the patient to a second resolutive endoscopy, it was necessary to obtain the hemodynamic stability. However the management of cases of accidental ingestion of foreign bodies is particularly difficult. Medical errors can arise from the very first contact with the patient resulting in delays in appropriate treatment. The doctor to avoid compromising its position on medical liability, must use all the knowledge and diligence known by the art and science of medicine.

  12. Acute appendicitis caused by foreign body ingestion

    PubMed Central

    Kim, Joo Heung; Lee, Dae Sup

    2015-01-01

    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.

    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.

    Objective To identify the computed tomography findings suggestive of intestinal perforation by an ingested foreign body. Materials and Methods This was a retrospective study of four cases of surgically proven intestinal perforation by a foreign body, comparing the computed tomography findings with those described in the literature. Results None of the patients reported having ingested a foreign body, all were over 60 years of age, three of the four patients used a dental prosthesis, and all of the foreign bodies were elongated and sharp. In all four patients, there were findings indicative of acute abdomen. None of the foreign bodies were identified on conventional X-rays. The computed tomography findings suggestive of perforation were thickening of the intestinal walls (in all four cases), increased density of mesenteric fat (in all four cases), identification of the foreign body passing through the intestinal wall (in three cases), and gas in the peritoneal cavity (in one case). Conclusion In cases of foreign body ingestion, intestinal perforation is more common when the foreign body is elongated and sharp. Although patients typically do not report having ingested such foreign bodies, the scenario should be suspected in elderly individuals who use dental prostheses. A computed tomography scan can detect foreign bodies, locate perforations, and guide treatment. The findings that suggest perforation are thickening of the intestinal walls, increased mesenteric fat density, and, less frequently, gas in the peritoneal cavity, often restricted to the point of perforation.

  15. Oroesophageal Fish Bone Foreign Body

    PubMed Central

    Kim, Heung Up

    2016-01-01

    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

    Introduction. Foreign body impaction (FBI) in the esophagus can be a serious condition, which can have a high mortality among children and adults, if appropriate diagnosis and treatment are not instituted urgently. 80–90% of all foreign bodies trapped in the esophagus usually pass spontaneously through the digestive tract, without any medical or surgical intervention. 10–20% of them will need an endoscopic intervention. Case Report. We hereby present a case of a large chicken piece foreign body impaction in the esophagus in a 25-year-old male with mental retardation. Patient developed hypoxemic respiratory failure requiring intubation. The removal required endoscopic intervention. Conclusions. Foreign bodies trapped in the upper gastrointestinal tract are a serious condition that can be fatal if they are not managed correctly. A correct diagnosis and treatment decrease the chances of complications. Endoscopic treatment remains the gold standard for extracting foreign body impaction. PMID:28058124

  18. Techniques for Intravascular Foreign Body Retrieval

    2013-08-01

    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.

    The topic of foreign body ingestion has received extensive coverage in the areas of surgery, emergency medicine and pediatrics. A subset of this topic, the intentional ingestion of foreign bodies, however, is much less common, and involves subtleties in evaluation and management not usually seen in accidental ingestions. Here, we report a case of ingestion of a rolled, metal tuna can lid in a male prison inmate previously diagnosed with depression and paranoid schizophrenia. Following evaluation by the surgical team, the foreign body was removed by laparotomy and the patient was discharged back to the prison without complication. In many cases, ingestions ofthis type involve a command hallucination ordering the patient to swallow the foreign body. Interestingly, the patient in the present case reported auditory hallucinations commanding him not to swallow the can lid.

  1. New classification of ocular foreign bodies.

    PubMed

    Shukla, Bhartendu

    2016-12-01

    Foreign bodies (FBs) in the eye are usually classified as intraocular (IOFB) or extraocular (EOFB). In IOFB the FB is within the eye ball and in EOFB it is outside. This classification seems oversimplified. Hence a new classification is proposed on the basis of FB locations, in which adnexal FBs (in orbit, lids, con- junctiva and lacrimal apparatus) are also included. These are further classified according to their exact location. FBs can also be classified in many other ways. Besides IOFB and EOFB, another condition IMFB (intramural foreign body) is also described. The FBs are situated within cornea or sclera and are neither IOFB nor EOFB. Ocular trauma also includes trauma to ocular adnexa and hence the terms IOFB and EOFB have been replaced by IGFB (intraglobal foreign body) and EGFB (extraglobal foreign body).

    Nasal foreign bodies in children are often managed in the pediatric emergency department. The child is usually between 2 and 4 years old, and the foreign body is most commonly a plastic toy or bead. Nasal foreign bodies are removed by a number of techniques. Positive-pressure expulsion is accomplished by orally applied pressure via a parent's mouth or an Ambu bag or by nasally applied pressure via a catheter or an oxygen source. The object can be washed out with nasally applied saline. Direct mechanical extraction is possible with a variety of tools, including forceps, hooks, or balloon-tipped catheters. Each method carries its own risks and benefits. Serious complications of nasal foreign bodies include posterior dislodgement and aspiration, trauma caused by the object itself or removal attempts, infection, and choanal stenosis. Magnets and button batteries require emergent removal as they carry the risk of septal perforation or necrosis, which may develop within a relatively short time.

    Retrieval of foreign bodies from the genitourinary system, most commonly inserted for sexual satisfaction or as a result of a psychiatric illness, can pose a significant surgical challenge. Due to their breadth of size, shape, and location within the genitourinary system, endoscopic management can be difficult.

    2013-01-01

    Neuropathic pain is caused by neural injury or painful states associated with either peripheral or central nerve injury. One of the aetiologies of this type of pain is iatrogenic trauma. This case highlights the features of peripheral neuropathic pain caused by foreign body left in the mental foramen following a previous surgical procedure. The foreign body was detected on routine radiographic evaluation. Once the foreign body was removed by surgical intervention, the pain resolved. This stresses the importance of routine radiographic evaluation in proper diagnosis and treatment planning in the management of neuropathic pain. This paper also sheds light on the role of iatrogenic mechanical cause of peripheral neuropathic pain and warrants a tough degree of caution on the part of oral clinicians. PMID:23819067

    2014-11-01

    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. In this article we describe the presentation, infectious profile, and treatment of these joint injuries.

    AIM To highlight the rising trend in hospital presentation of foreign bodies retained in the rectum over a 5-year period. METHODS Retrospective review of the cases of retained rectal foreign bodies between 2008 and 2012 was performed. Patients’ clinical data and yearly case presentation with data relating to hospital episodes were collected. Data analysis was by SPSS Inc. Chicago, IL, United States. RESULTS Twenty-five patients presented over a 5-year period with a mean age of 39 (17-62) years and M: F ratio of 2:1. A progressive rise in cases was noted from 2008 to 2012 with 3, 4, 4, 6, 8 recorded patients per year respectively. The majority of the impacted rectal objects were used for self-/partner-eroticism. The commonest retained foreign bodies were sex vibrators and dildos. Ninty-six percent of the patients required extraction while one passed spontaneously. Two and three patients had retrieval in the Emergency Department and on the ward respectively while 19 patients needed examination under anaesthesia for extraction. The mean hospital stay was 19 (2-38) h. Associated psychosocial issues included depression, deliberate self-harm, illicit drug abuse, anxiety and alcoholism. There were no psychosocial problems identified in 15 patients. CONCLUSION There is a progressive rise in hospital presentation of impacted rectal foreign bodies with increasing use of different objects for sexual arousal. PMID:27830039

    We present the rare case of a violence-related accident involving a periorbital foreign body and surgical treatment. A 43-year-old man was brought to the hospital with a foreign body lodged in his left eyelid. A ballpoint pen penetrated the upper lid and orbital floor and reached the maxillary sinus.The spring of the ballpoint pen was observed in the radiograph, but the other parts of the ballpoint pen were not seen.The ballpoint pen was retrieved along the path of insertion. The fractured part of the orbital floor was slightly enlarged with a drill to allow visual access during surgery. Plastic pieces and the spring of the pen were removed under endoscopy inside the maxillary sinus. The inferior orbital wall was successfully reconstructed and there were no postoperative complications.The unique features of this case include the nature of the foreign body and its trajectory; removal was particularly challenging because the foreign body was not clearly visible in the radiograph.

    Clinical data and computed tomography (CT) studies were reviewed for 13 dogs with confirmed nongastrointestinal foreign bodies. Locations of foreign bodies were the nasal cavity, thoracic wall, retropharyngeal region, and cerebellum. Types of foreign bodies included small plant components, blades of grass, wooden sticks, cloth fibers, and a needle. Foreign bodies in five dogs were not identified on CT, and secondary reactions resembled neoplastic or fungal disease. In eight dogs, foreign bodies were recognized by their shape and/or internal architecture. In two dogs, three-dimensional reformatting helped demonstrate foreign bodies in relation to palpable bony landmarks.

    Foreign body ingestion (FBI) is a common problem in the pediatric population. Even though morbidity and mortality due to foreign body ingestion are rare in childhood, they may cause serious anxiety in parents. We aimed to analyze the clinical presentation, etiology and management strategy of FBI in children in our country. Records of children admitting with a history of FBI over a three-year period were reviewed retrospectively. Data regarding gender, age, type of the ingested body, management strategy and outcome of the patients were recorded. Of 176 children, 98 (55.6%) were male. Mean age +/- SD of the patients was 3.75 +/- 4.25 years, and most of the patients were below four years of age (71.5%). Most of the children (64.7%) were seen within 48 hours, and most were asymptomatic. Blue beads attached to a safety pin (a cultural good luck charm) (38.6%), coins (27.8%) and turban pins (18.1%) were the most commonly observed foreign bodies. The blue beads/safety pin were found to be ingested primarily by infants, while ingestion of turban pins was mostly seen in adolescent girls who covered their heads. Localization of the foreign bodies was in the distal small intestine, stomach and esophagus in 61.4%, 23.8% and 14.7% of the cases, respectively. Sixty-nine endoscopic interventions were performed in 61 patients (34.6%), and these accounted for 7.3% of all endoscopic interventions during the three-year period. No major complication was observed during the procedure, and none of the patients underwent surgery. The frequently used accessory devices were retrieval net basket (57.9%), snare for pins (17.3%), tripod forceps and rat-tooth forceps. The blue beads/safety pin and turban pin were the commonly ingested foreign bodies in our center due to cultural factors. Education of the parents and of adolescent girls should greatly reduce the incidence of FBI. Endoscopic removal is safe without any major complications.

    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

    Exact localization of foreign body is important for planning the treatment required for its retrieval without much tissue damage. Plain film radiography is the initial screening modality used for the detection of suspected foreign body. However, about one-third of all the foreign bodies are missed in the initial radiographic examination. In case of a wooden foreign body, only 15% are well-visualized on plain radiographs and are, therefore, often missed or misdiagnosed. Hence, the different radiographic technique should be used to localize the object instead of relying on a single radiographic image. Here, we present a unique case of foreign body entrapped in the soft tissue appeared initially as osteomyelitis and fracture of the mandible in the digital panoramic radiograph, and finally detected as a foreign body in mandibular occlusal radiography.

    Introduction: Foreign body aspiration is usually a serious condition that is most common among the pediatric population, and rare in adults. In adults, aspiration may be tolerated for a long time. Case Reports: Our first case is a 38-year-old man who presented with a 2-day history of swallowing a foreign body. He was completely asymptomatic. Chest X-ray revealed the presence of 5-cm foreign object in the right main bronchus. Rigid bronchoscopy was performed and a knife was removed from the right main bronchus. Second, a 57-year old man with a known case of laryngeal cancer from 15 years previously was admitted for respiratory distress. He had previously undergone a permanent tracheostomy and had received radiotherapy for his cancer. At the first visit, the patient had prominent distress and was transferred to the operating room as an emergency. A tube was seen on chest X-ray. On bronchoscopy, we found the tracheostomy situated in the carina. The cleaved tracheostomy was removed using the grasper, by grasping the cuff line. Conclusion: We conclude that foreign body aspiration might be completely asymptomatic, especially in an adult. A good history and imaging findings can help us to diagnose and treat the condition carefully. PMID:28229065

    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

    Medical records of all prepubertal patients who underwent vaginoscopy to rule out vaginal foreign body between 2004 and 2013 were reviewed retrospectively. All patients were evaluated by pediatricians prior to surgical consultation. Vaginoscopy is performed in the operating room under general anesthesia. During the study period, 20 girls with persistent vaginal discharge with a mean age of 6.8 years (1-13 years) underwent vaginoscopy to rule out vaginal foreign body. Six patients had bloody vaginal discharge and 4 had recurrent vaginal bleeding lasting for more than one month. Ten patients had purulent vaginal discharge lasting for 1-7 months. None of vaginal cultures revealed pathological bacteria or candida species. Preoperative imaging techniques revealed vaginal foreign body in one patient only. Vaginoscopy demonstrated vaginal foreign bodies in four patients. Foreign bodies were grass inflorescence, safety pin and undefined brownish particles (n=2), which may be pieces of toilet paper or feces. There was no complication related to vaginoscopy and removal of foreign body. Hymen integrity was preserved in all patients. Persistent or recurrent vaginal discharge in prepubertal girls should raise the suspect of vaginal foreign body. Continuous flow vaginoscopy is mandatory to detect and remove any vaginal foreign body. Early diagnosis would prevent complications secondary to long-standing foreign bodies.

    Five patients were surgically treated for intraorbital foreign body: a 14-year-old girl had a door glass splinter, a 23-year-old man a metallic foreign body--gunshot pellet, a 55-year-old man a splinter from a metallic bar, a 48-year-old patient the splinters of circular saw and 61-year-old man with shot. Two foreign bodies were removed using the Krönlein-Reese-Berk lateral orbitotomy, two others by Sewell medial orbitotomy and one with superior orbitotomy of Dandy-Naffziger. Radiographs and CT scans were used to identify and localize intraorbital foreign bodies. In one case we found coexistence foreign body (shot) and tumor--inflammation pseudotumor of the orbita. It is possible, that in this case long-time occupy foreign body in the orbita was a cause of that tumor. All foreign bodies were successfully removed, and postoperative course was uneventful. The Krönlein-Reese-Berk orbitotomy provides a satisfactory access to the lateral and posterior orbit, which is of particular importance in the case of a deeply penetrating foreign body (metallic or glass). Surgical removal of intraorbital foreign bodies is a classic example of an interdisciplinary therapeutic approach. Best outcome is usually a result of a team of an ophtalmologist, ENT surgeon, maxillary surgeon and possibly also neurosurgeon performing the operation.

    Sinonasal foreign bodies are rare clinical entities. Their presence in the sinuses can originate complications, so their removal is always indicated. We present 3 cases of sinonasal foreign body, indicating their symptoms, imaging findings and surgical removal. Each patient was assessed with computerized tomography of the sinuses, rigid endoscopy, and then surgical removal. We confirmed the presence of the foreign bodies in all 3 cases and then performed a successful surgical removal by transnasal endoscopy. Sinonasal foreign bodies are infrequent entities that require surgical removal to prevent complications, with transnasal endoscopic surgery being the most commonly used surgical approach.

    Despite new equipment, such as the Hopkins rod-lens telescopes and optical forceps, foreign bodies in the airway continue to present a diagnostic and therapeutic challenge to the endoscopist. Airway foreign bodies are more common in children than adults and frequently, the patient may have aspirated more than one foreign body or the original foreign body fragments into pieces. Vegetable matter is the most frequently aspirated material by children. This material can swell as it absorbs water, it can cause an intense mucosal reaction and it can fragment during removal. A case with endoscopic photographs demonstrating these issues and a discussion are presented. PMID:18493458

    Foreign body ingestion and aspiration in children has been a serious problem, occasionally resulting in airway obstruction and death. Airway obstruction by balloons and subsequent asphyxiation is well documented. Respiratory blockage by plastic dry-cleaning sacks has resulted in warning labels on most such materials. Two recent cases of nasal aspiration of plastic coating from a commonly used disposable diaper are compared to reports of similar occurrences documented by the U.S. Consumer Product Safety Commission. On the basis of these reports we recommend that disposable diapers be continuously covered by other clothing to prevent the child's access to the plastic. Otolaryngologists and pediatricians should be aware of the potential hazard when examining diapered children with chronic rhinorrhea or sudden respiratory distress.

    Occupational lung diseases are caused by several toxic substances including heavy metals; however, the exact pathologic mechanisms remain unknown. In the workplace, dental technicians are often exposed to heavy metals such as cobalt, nickel, or beryllium and occasionally develop occupational lung diseases. We described a case of occupational lung disease in a patient who was employed as a dental technician for over a decade. A 31-year-old, non-smoking woman presented with productive cough and shortness of breath of several weeks duration. Chest computed tomography revealed a large number of scattered, bilateral small pulmonary nodules throughout the lung field, and multiple mediastinal lymph nodes enlargement. Percutaneous needle biopsy showed multifocal small granulomas with foreign body type giant cells suggestive of heavy metals inhalation. The patient's condition improved on simple avoidance strategy for several months. This case highlighted the importance of proper workplace safety.

    Injection of the subcutaneous tissues of the penis for enlargement of penile girth has been practised for many years by laypeople and medical practitioners alike. However, with recognition of the complications, the practice has died out. We report a series of five patients who presented having injected foreign materials into the subcutaneous tissues of their penises, including paraffin and mineral oils. Our patients had a variable time course of presentation ranging from 1 day following injection to over 26 years. Self-injection of the subcutaneous tissues of the penis is an unusual presentation for a penile mass but should be considered as a differential diagnosis in patients with a long latent period to presentation or with characteristic magnetic resonance imaging and histological appearances.

    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.

    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

His parents gave a preceding uncertain history of a foreign body injury to his left eye 3 months ago while playing. Presenting visual acuity in the left eye was perception of hand movements. Slit-lamp examination revealed a total white cataract with brownish-pigmented spots on the anterior capsule of the lens, but no intraocular foreign body was found. There was also no evidence of an intraocular foreign body on ultrasonography. Patient underwent cataract extraction with intraocular lens implantation. During the operation, a small (2×1×1 mm in size) intralenticular foreign body of metal material was found and removed carefully with a magnet. The patient regained 20/30 vision after surgery.

    Patients with impacted esophageal foreign bodies usually present with gastrointestinal and rarely with respiratory symptoms. Impacted esophageal foreign bodies may be identified by radiologic studies. Ingested radiolucent foreign bodies may be more difficult to diagnose, especially if the patient presents with minimal symptoms. We report a rare case of a child who presented with stridor and obstructive sleep apnea. The cause of respiratory symptoms was thought to be due to enlarged tonsils and adenoids, and the patient was scheduled for tonsillectomy and adenoidectomy. On re-evaluation by the surgeon on the day of surgery, the procedure was changed to diagnostic microlaryngoscopy and bronchoscopy to rule out any other cause. The patient's respiratory symptoms were resolved when an incidental discovery and retrieval of the radiolucent esophageal foreign body was made. The diagnosis of radiolucent esophageal foreign body can be difficult and can be easily missed without reasonable clinical suspicion.

    Foreign bodies and tissue reactions to foreign materials are commonly encountered in the oral cavity. The more common lesions include apical deposition of endodontic materials, mucosal amalgam and graphite tattoos, myospherulosis, oil granulomas, and traumatically introduced dental materials and instruments. Since many foreign materials are unidentifiable histologically, commonly used dental materials were experimentally implanted subcutaneously in rats to assess local host responses and characterize the nature of these materials microscopically. The histologic characteristics of these foreign body reactions are detailed herein. The implanted materials corresponded to reactions seen in human subjects.

    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

Since the act may go unnoticed, the child may present late. However, most foreign bodies pass spontaneously in the stools. Case Capsule: Two children were brought with history of battery ingestion. In one case, an emergency gastro intestinal endoscopy had to be done for the foreign body removal which was made up of corroded battery. In the other case, no interventation was undertaken & an uncorroded battery passed per anum along with stools after 15 days of ingestion. Conclusion: Decision regarding immediate intervention or conservative approach will require consideration of the level of lodgement & type of foreign body. Prevention is possible if parents/guardians exercise control on their wards & are aware of implications of such an event. PMID:25657965

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

    Granulomas are rarely seen in gastric biopsies mostly as an involvement of granulomatous diseases like sarcoidosis, Crohn's disease, infections, neoplasms, and vasculitis. Here, we claim cyanoacrylate as a foreign body type granuloma-causing agent in the stomach after vascular embolisation. We present cyanoacrylate associated gastric changes of three cases: two endoscopic biopsies and one gastric resection. In two cases, cyanoacrylate associated ulcers and granulomatous inflammation were observed in gastric mucosal biopsies following endoscopic examination after 7 months and 6 years of the glue injections, respectively. In the third case, the cyanoacrylate injection was performed 2 months prior to the surgery. Then the patient underwent distal pancreatectomy for pancreatic adenocarcinoma and during the operation a gastric mass was resected with a suspicion of tumoral infiltration. These three cases demonstrated that glue exposure causes active chronic inflammation with foreign body type granulomas, mucosal ulceration, and bleeding in the gastric mucosa. Even further, it can induce mass formation in the injection sites. PMID:28203472

    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.

    Detection of non-radio-opaque foreign bodies can be difficult. Current imaging modalities employed for detection of foreign bodies include: X-ray computed tomography, magnetic resonance, and ultrasound. Successful diagnosis of the presence of foreign bodies is variable because of the difficulty of differentiating them from soft tissue, gas, and bone. We are applying laser-induced optoacoustic imaging to the detection of foreign bodies. Tissue-simulating phantoms containing various common foreign bodies have been constructed. Images of these phantoms were generated by two laser-based optoacoustic methods utilizing different detection modalities. A pre-commercial imager developed by Seno Medical Instruments (San Antonio), incorporated an ultrasound transducer to detect induced optoacoustic responses, while a laboratory-built imaging system utilized an optical probe beam deflection technique (PBDT) to detect the optoacoustic responses. The laboratory-built unit also included an optical parametric oscillator as the pump, providing tunable wavelength output to optimize the optoacoustic measurements by probing the foreign bodies at their maximum optical absorption. Results to date have been encouraging; both methodologies have allowed us to reconstruct successfully the image of foreign-body containing phantoms. In preliminary work the PBDT approach appeared to produce higher resolution than did the ultrasound detector, possibly because PBDT is not constrained by the lower bandwidth limit imposed on the ultrasound transducer necessary to increase imaging depth. During the research in progress, we will compare the optoacoustic images to those generated by MRI, CT, and ultrasound, and continue to improve the resolution of the technique by using multiple detection sensors, and to improve image contrast by scanning foreign bodies over a range of wavelengths.

    This case report describes a foreign body retained in the liver long after perihepatic gauze packing. A 64-year-old female patient had suffered a rib fracture and liver rupture during a traffic accident in 1973. She discovered a mass in her right hypochondrium. Her hepatic ultrasonography showed a round mass (20.3 cm × 17.3 cm × 16.0 cm in size) with fluid echogenicity in the right lobe of her liver, and a hepatic cystic-solid mass (19.7 cm × 18.5 cm × 15.6 cm in size) was identified in an abdominal computerized tomography scan. Several pieces of gauze were extracted, and brown pus from the hepatic mass was suctioned during her exploratory laparotomy. Histology documented gauze remnants with necrotic material inclusions and fibrotic capsules. To our knowledge, this patient’s case represents the longest time for which a foreign body has been retained in the liver. In addition, we conducted a comprehensive literature review of foreign bodies retained in the liver. Foreign bodies may be introduced into the liver via penetrating trauma, surgical procedures or the ingestion of foreign bodies (which then migrate from the gut). Thus, they can be classified into the following three categories: penetrating, medical and migrated foreign bodies. The details of the case are thoroughly described. PMID:23745042

    Optoacoustic imaging is an emerging medical technology that uniquely combines the absorption contrast of optical imaging and the penetration depth of ultrasound. While it is not currently employed as a clinical imaging modality, the results of current research strongly support the use of optoacoustic-based methods in medical imaging. One such application is the diagnosis of the presence of soft tissue foreign bodies. Because many radiolucent foreign bodies have sufficient contrast for imaging in the optical domain, laser-induced optoacoustic imaging could be advantageous for the detection of such objects. Common foreign bodies have been scanned over a range of visible and near infrared wavelengths by using an optoacoustic method to obtain the spectroscopic properties of the materials commonly associated with these foreign bodies. The derived optical absorption spectra compared quite closely to the absorption spectra generated when using a conventional spectrophotometer. By using the probe-beam deflection technique, a novel, pressure-wave detection method, we successfully generated optoacoustic spectroscopic plots of a wooden foreign body embedded in a tissue phantom, which closely resembled the spectrum of the same object obtained in isolation. A practical application of such spectra is to assemble a library of spectroscopic data for radiolucent materials, from which specific characteristic wavelengths can be selected for use in optimizing imaging instrumentation and provide a basis for the identification of the material properties of particular foreign bodies.

    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.

    Deliberate single foreign body ingestion is a scenario that many gastroenterologists commonly see in psychiatric units and prisons. However, multiple foreign body ingestions, especially located in the duodenum, provide the endoscopist with unique challenges for management and treatment. Although most foreign objects pass spontaneously, one should have a low threshold of intervention for multiple objects, especially those that are wide, sharp and at risk of perforation. Diagnosis is typically made when there is a history of ingestion coupled with corresponding radiographic verification. The symptoms tend to be non-specific although some patients are able to delineate where the discomfort level is, correlating with the site of impaction. Most foreign bodies pass spontaneously; however when multiple sharp objects are ingested, the gastroenterologist should perform endoscopic procedures to minimize the risks of bowel perforation. We describe here a successful case of multiple ingested foreign bodies retrieved across the C-loop of the duodenum and the pharynges-esophageal curve via endoscopy and review the literature of multiple foreign body ingestion.

    Urinary bladder functions for the storage and expulsion of urine. Foreign bodies in male urinary bladder are rare due to lengthy urethra, especially when they are rounded in shape and difficult to be introduced into urinary bladder. This is a case report of a middle age male with thin body habitus and slightly disturbed psychiatric status. He presented with both irritative and obstructive lower urinary tract symptoms (LUTS). He was investigated and found to have an intact bangle in the urinary bladder. The patient was planned for surgery, and the foreign body was removed endoscopically with the help of cystoscope. Later on the patient was referred to a psychiatrist for psychological management.

    Two cases with a urethrovesical foreign body in adolescent boys are reported. Case 1 was a 12-year-old boy with a stretched safety pin, 7 cm in length, in the urethra. This was probably introduced by him. Case 2 was a 14-year-old boy with a self-introduced metallic bar, 5 cm in length, in the urinary bladder. The foreign bodies were endoscopically removed. Both of the boys had grown in fatherless families. In Case 1, his father had died in a traffic accident while trying to save the patient at the age of 5 years. In case 2, the parents had been divorced. These episodes could have resulted in mental instability in the boys, which possibly led to the self-introduction of the foreign body. Urethrovesical foreign bodies are not rare. However, a foreign body in adolescents under 15 years of age is very rarely reported. It is incumbent upon urologists to thoroughly investigate the psychological conditions in such cases, and to properly judge whether psychiatric cares and follow-up are necessary.

    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

    Believe it or not, once upon a time, to remove a foreign body from the ear canal, the clinicians used to introduce the severed head of a living lizard which was still then gasping for breath. It was hoped that, the opening and closing jaw movements of the gasping lizard would at one time grasp the Foreign Body. Afterwards the removal of the lizard's head would also lead to the removal of the Foreign Body.Today the safe and simple removal is not considered as the ultimate treatment of Foreign body. Amongst the victims of self introduced Foreign bodies, are mostly children. Specially those who do it repeatedly and on others, are thought to be mentally retarded or frustrated. Such children should be subjected to Psychoanalysis and if the said study confirms one to be so, he should be given appropriate treatment. This will help him to grow normally by alleviating his various other behavioural disorders. In addition, it will stop his tendeny to do it again and save him suffering from problems of other mental disorders which can crop up in his future life if left untreated.

    Intracranial wooden foreign bodies are rare. In addition, such objects are difficult to identify with conventional radiographic techniques, such as X-ray radiography or brain computed tomography. A 48-year-old man presented to our emergency room with a headache. Even though he had a history of trauma, he had no external wounds and showed no neurological deficits at the initial examination. He was initially diagnosed with trauma-related pneumocephalus. He developed a delayed intracranial infection and underwent surgery to remove the wooden foreign body. The present case illustrates the necessity for special attention to patients suspected of having pneumocephalus with a rare presentation during the initial examination. Early surgical removal of the intracranial foreign body is necessary to prevent complications. PMID:27857924

    Ingestion of foreign bodies is an avoidable accident that is seen mainly in children under 3 years-old. Most of them pass through the digestive tract without causing clinical manifestations or complications, but a significant percentage is impacted in the esophagus causing vomiting, sore throat, dysphagia and drooling. The most common foreign bodies are coins. Complications usually occur when there is a delay in diagnosis or with large, sharp or potentially toxic objects, as the button battery. It is essential to make differential diagnosis between coin and button battery, since the latter requires urgent removal due to the earliness of the injury caused. We report 115 cases of foreign bodies in the esophagus, and we alert the pediatrician in recognizing and preventing this problem.

    The multiple variant of aero-digestive foreign bodies' pathology determine many complex aspects with regard to their physiopathology, nature, and their location. The presence of a medical handicap or any particular condition could increase morbidity and expose to major risks. We are reporting here about 4 cases including an esophagus foreign body in a leprosies patient, an esophago-gastric case in a mental disorder patient, and two laryngeal-tracheal-bronchial cases during epileptic episodes. From the rarity of such accidents in an adult to their happening during a loss of consciousness or a delirious state, the clinical history is always missing. The symptoms are atypical and may misguide. The classical penetration syndrome cannot be reported. Only a clinical examination carefully conducted and completed with targeted para clinical examinations can help make early diagnosis. Endoscopy of the Esophagus on one hand, and endoscopy of the trachea and lungs on the other hand were used to extract these foreign bodies.

    We present the case of a patient who suffered a cardiac penetrating trauma due to a 6-cm long steel splinter. He was self-admitted to the emergency room and was asymptomatic. Cardiac trauma was diagnosed by the presence of a foreign body in his chest X-ray. Transthoracic and transesophageal echocardiography showed pericardial effusion and a dense foreign body that crossed the left ventricle from upside down and forward to back. The patient underwent cardiac surgery under extracorporal circulation. A shooting wound was seen on the left ventricular free wall. Transesophageal echocardiography was performed during surgery in order to define the position of the foreign body and to discard lesions due to multidirectional injury. Lesions were repaired and the patient was discharged with no complications. This case report illustrates the possibility of survival after cardiac penetrating trauma, and the role of echocardiography in the diagnosis and surgical repair of this type of trauma.

    Tracheobronchial foreign body aspiration is a serious medical problem, with clinical manifestations ranging from acute asphyxiation to insidious lung damage, as demonstrated by the three presented cases. Patient 1 aspirated during dinner, emergency bronchoscopy retrieved pieces of food, and she fully recovered the following day. Patient 2 presented with recurrent pneumonia and a right lower lobe lung abscess. After right lower lobectomy, pathology revealed a foreign object in the right main stem bronchus, a peanut aspirated one year earlier. Patient 3 became unresponsive several days after spinal surgery. The differential diagnosis included myocardial infarction, stroke, and foreign body aspiration. The patient died and necropsy revealed a foreign body in the right main stem bronchus (cooked meat). Thus, foreign body aspiration is not always suspected clinically, and the pathologist may play an important role in making the diagnosis. Histological identification of the aspirated material may be necessary for definitive diagnosis. Therefore, sections of commonly aspirated foods are presented, together with a 10 year history of aspirated objects received by this institution's surgical pathology department.

    The foreign body reactions are commonly referred to the network of immune and inflammatory reactions of human or animals to foreign objects placed in tissues. They are basic biological processes, and are also highly relevant to bioengineering applications in implants, as fibrotic tissue formations surrounding medical implants have been found to substantially reduce the effectiveness of devices. Despite of intensive research on determining the mechanisms governing such complex responses, few mechanistic mathematical models have been developed to study such foreign body reactions. This study focuses on a kinetics-based predictive tool in order to analyze outcomes of multiple interactive complex reactions of various cells/proteins and biochemical processes and to understand transient behavior during the entire period (up to several months). A computational model in two spatial dimensions is constructed to investigate the time dynamics as well as spatial variation of foreign body reaction kinetics. The simulation results have been consistent with experimental data and the model can facilitate quantitative insights for study of foreign body reaction process in general. PMID:21532988

    In evaluating the gastrointestinal tract, whether in the emergency room setting, the inpatient setting or the outpatient setting, the radiologist may encounter a myriad of intraluminal radio-opaque, non-anatomic entities. It is the radiologist's role to distinguish between true foreign bodies and medical paraphernalia. Further, the later must be evaluated for proper positioning vs. improper, potentially detrimental positioning. While many foreign bodies from the community may be distinctly familiar to the radiologist, the large variety of medical tools in existence may not be. Furthermore, many medical devices are designed to transiently traverse, or interact with the gastrointestinal tract, requiring the radiologist to become familiar with their natural history. We explore a select group of common and uncommon intraluminal foreign bodies and will divide them into medical paraphernalia that are properly positioned; medical paraphernalia that are in abnormal locations and miscellaneous foreign bodies from the community. For each medical tool, we will discuss its development and medical utility, natural history as it relates to the gastrointestinal tract, optimal positioning as assessed radiologically, malpositioning, and subsequent complications. A small selection of unusual foreign bodies from the community will be presented. Finally, a selection of medical conditions which produce symptoms due to acquired intraluminal objects will be reviewed.

    Intracranial foreign body granulomas are rarely reported. Clinical symptoms caused by foreign body granulomas can be noticed from months to many years after surgical procedure. The most common reported etiology is suture material. A 45-year-old woman was presented with grand mal epilepsy. She was operated for brain tumor 19 years ago. In CT scan, a round radio-dense mass resembling a tumor at anterior fossa was seen. She underwent craniotomy and resected a granuloma with cotton fibers surrounded by yellow capsule without residual or recurrent tumor. Granuloma can mimic intracranial meningioma and special attention should be paid not to leave cotton pledgets during operations. PMID:22091258

    The aspiration of a foreign body remains a common paediatric problem, with serious consequences that can produce both acute and chronic disease. Aspiration usually causes a medical emergency that requires a prompt diagnosis and an urgent therapeutic approach as it may result in the death of the child or severe brain injury. It typically involves organic foreign bodies (mainly food or nuts) aspirated by children under 5 years old, and usually at home. In this statement, the Committee on Safety and Prevention of Non-Intentional Injury in Childhood of the Spanish Paediatrics Association provides a series of recommendations, both educational (while eating and playing), as well as legal, to prevent such episodes.

    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.

    Foreign bodies being forced into the esophagus as a form of fatal child abuse is rare. A 4.5-month-old female infant presented to clinicians with respiratory distress. Several coins were recovered from the esophagus. One month later, she was found dead in her crib. At autopsy, there were three coins in the esophagus. In addition, there were cutaneous contusions of various ages, acute and partially healed fractures of the extremities, old aspirated foreign material in the lungs, and pulmonary fat emboli. Although the fat emboli may have contributed to the death, several potentially fatal mechanisms from the esophageal foreign bodies deserve consideration. These include vagal stimulation from esophageal distention, aspiration of swallowed fluids after esophageal obstruction, compression of the trachea or the heart by the coins, and cardiac compression or airway occlusion by the introducing finger.

They have potentially harmful consequences for the patient as they can be life threatening and usually, a further operation is necessary. The incidence of RSB is between 0.3 to 1.0 per 1,000 abdominal operations, and they occur due to a lack of organisation and communication between surgical staff during the process. Typically, the RSB are surgical sponges and instruments located in the abdomen, retroperitoneum and pelvis. PMID:28293325

    Summary Background Foreign body in the lower urinary tract has a low incidence. Here we discuss a case of a safety pin within the bulbar urethra inserted by a young boy for sexual gratification, which was successfully removed under cysto-urethroscopic guidance. Case Report Herein we present a case of a 14-year-old boy who presented with complaints of perineal pain and dysuria. On evaluation in detail and from clinical history, we came to know that he had inserted a safety pin within the urethra. Urine analysis revealed microscopic haematuria and few pus cells. X-ray of the pelvis and computerised tomography helped in confirming the presence of the safety pin within the urethra. Conclusions The method of extraction of a foreign body per urethra depends on the size and shape of the foreign body. Cysto-urethroscopic removal is successful depending on the physical characteristics of the foreign body. It has the advantage of minimising urothelial trauma and also helps in assessing any previous mucosal injury or thickening. Psychological evaluation and counselling may help to prevent further such episodes. PMID:27867440

  15. The anaesthetic consideration of tracheobronchial foreign body aspiration in children

    PubMed Central

    2016-01-01

    Cases of tracheobronchial foreign body aspiration are frequently encountered emergency cases of childhood; and, delays in its recognition and treatment do result in serious morbidity and mortality. Diagnosis mainly relies on taking history which should indicate what the foreign body is, when it has been aspirated and where it is located. Belated consultation can cause misdiagnosis with the mixing of the symptoms and data with those of other pathologies common to childhood and further delays in the correct diagnosis. Bronchoscopy is required for the differential diagnosis of suspected tracheobronchial foreign body aspiration in order to eliminate other common pediatric respiratory concerns. Given the shared use of the airways by the surgeon and the anaesthesiologist, bronchoscopy is a challenging procedure requiring experienced teams with an efficient method of intercommunication, and also well planning of the anaesthesia and bronchoscopy ahead of the procedures. Despite the recent popularisation of the fiberoptic brochoscopes, the rigid bronchoscopy remains to be used commonly and is regarded to provide the gold standard technique. There have been reports in the literature on the uses of inhalation and/or intravenous (IV) anaesthesia and spontaneous or controlled ventilation methods without any demonstration of the superiority of one technique over the other. The most suitable methods of anaesthesia and ventilation would be those that reduce the risks of complications, morbidity and mortality; and, preventive measures should be taken with priority against childhood cases of tracheobronchial foreign body aspiration.

    Pulmonary granulomas were induced in BALB/c mice by the intratracheal injection of insoluble polymerized dextran and latex microparticles. Very large granulomas developed around dextran beads, which reached peak intensity within 2-3 days and rapidly declined in size thereafter. Latex beads generated small stable lesions. The involvement of cell-mediated immunity could not be demonstrated in the inflammatory responses induced by either type of bead. Antigen-induced delayed type hypersensitivity (DTH) and mitogen-induced DTH-like footpad reactions were markedly suppressed in immunized mice bearing early dextran granulomas. Mitogen-induced DTH-like footpad reactions were suppressed in unimmunized animals bearing early dextran foreign-body granulomas. Antigen- and mitogen-induced footpad swelling recovered to normal levels as dextran granulomas diminished in size. No suppression of these footpad reactions was observed in mice bearing small latex foreign-body granulomas. The intraperitoneal injection of aqueous extracts prepared from the lungs of unimmunized donor animals bearing early dextran foreign-body granulomas could partially transfer suppression of mitogen DTH-like footpad responses to normal mice. These results suggest that cells within large, nonimmunologic lung granulomas produce a soluble factor which participates in the expression of anergy-like immunosuppression.

    Foreign bodies should be removed from wounds during the primary wound management stage whenever possible. Metallic fragments can be identified and localized by conventional radiography, computed tomography, sonography, x-ray image intensifier, or electromagnetic metal detector. Locating metallic objects may still cause problems for the surgeon during the removal procedure. Detection and removal of superficial ferromagnetic fragments (iron, nickel, and cobalt) by a magnet is possible. In the literature the authors found no report about using the magnet for this purpose. Having conferred with the manufacturer KANAT (Istanbul, Turkey), the authors used a magnet made of neodymium. The power of the magnet was 12,000 gauss. It was cylindrical and 1.3 x 0.8 cm in diameter. This method was used in 6 patients successfully for localization and removal of ferromagnetic foreign bodies. Use of a magnet is an easy and cost-effective method that does not require education and specific staff.

    An 82-year-old man presented with signs and symptoms that were suggestive of acute cholecystitis. He underwent a laparoscopic cholecystectomy. During the intervention, a wooden foreign body was removed from the infiltrated omentum, probably after it had perforated the gastric antrum. The gastric perforation had led to a secondary infection of the gallbladder. The presumed gastric perforation was treated conservatively, and the patient recovered well and was discharged after 7 days. Secondary inflamed gallbladders are rare; the current case is, to the best of our knowledge, the first case reporting a secondary infection of the gallbladder due to a gastric perforation. Clinicians should be aware of possible ingestion of foreign bodies in elderly patients wearing dental prosthetic devices.

    An 82-year-old man presented with signs and symptoms that were suggestive of acute cholecystitis. He underwent a laparoscopic cholecystectomy. During the intervention, a wooden foreign body was removed from the infiltrated omentum, probably after it had perforated the gastric antrum. The gastric perforation had led to a secondary infection of the gallbladder. The presumed gastric perforation was treated conservatively, and the patient recovered well and was discharged after 7 days.

    Ingestion of foreign bodies is not an uncommon problem in our society. The patients usually ingest different types of foreign bodies either accidentally or deliberately. Rare in children but adults are not uncommonly affected and are either psychiatric patients or ingest foreign bodies accidentally. Life threatening complications may occur at times due to ingestion of sharp and pointed objects. An interesting case of ingestion of multiple injurious foreign bodies presenting with multiple small intestinal perforations is presented with review of literature.

    This is an interesting case report of a foreign body (FB) aspiration in an adult patient. The FB in question was a dental drill, which accidentally went into the airways during a dental procedure. The extraction was technically difficult due to the peripheral location and thin and sharp tip of the FB. The extraction of this FB required a unique innovation through the rigid bronchoscope.

  5. Intravascular foreign bodies: danger of unretrieved fragmented medical devices.

    Tateishi, Minori; Tomizawa, Yasuko

    2009-01-01

    A warning on the danger of unretrieved device fragments and recommendations to mitigate the danger were issued by the Food and Drug Administration in January 2008. The causes of intravascular foreign bodies are classified into three main categories: improper manipulation and usage, device defects, and others, such as patient and anatomical factors. Device failure after long-term use is rarely predicted at the time of approval, since device abnormality is rarely experienced in animal studies and clinical trials conducted during development of the device. Stent fracture due to metal fatigue is one example. Complex complications could occur from simultaneous use of two or more devices with diverse characteristics. The success rate of percutaneous retrieval of intravascular foreign bodies has improved with the advances in commercially available devices. However, the procedure is not always successful and sometimes surgical removal becomes necessary. Appropriate device selection and acquisition of experience in using the device are important. When an intravascular foreign body cannot be retrieved, the risk of complication could be high. Magnetic resonance imaging examination sometimes causes adverse events, including burns due to the heat generated by metal movement. Such information should be correctly recorded. Furthermore, it is necessary to provide patients with adequate information about the characteristics of implanted devices and unretrieved fragments. We reviewed the literature on unretrieved medical device fragments and include articles that describe the Japanese experience.

    The study purpose was to determine the ability of hand-held metal detectors (HHMDs) to identify the presence of ingested metallic foreign bodies (MFBs). Twenty-three children presenting to the emergency department with a complaint of MFBs ingested were enrolled. Sixteen of 23 patients had radiographically proven foreign bodies. The MFBs comprised coins (n = 11), a button battery (n = 1), a medallion (n = 1), a token (n = 1), a needle (n = 1), and a marble (leaded glass) (n = 1). The HHMD correctly detected 15 of 16 radiographically positive MFBs (93%) and correctly excluded a potential MFB in six of six radiographically negative cases. The only foreign body not detected was an ingested needle. One radiograph was equivocal. Radiographic localization of the ingested objects was as follows: esophagus, n = 4; stomach, n = 9; and intestines, n = 3. The HHMD correctly localized all detected MFBs. The HHMD had a sensitivity of 94%, a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 86%. HHMDs are effective screening devices for possible ingested MFBs. Positive studies localized to the stomach and lower gastrointestinal tract do not require confirmatory radiographic studies.

    A foreign body in the larynx is an airway emergency that requires urgent evaluation and treatment. Irregular foreign bodies tend to orient in a sagittal plane and may produce only partial obstruction, allowing adequate air movement, hence making them undetectable for a long period of time.

    Foreign body ingestion is a common condition, especially among children who represent 80% of these emergencies. The most frequently ingested foreign bodies in children are coins, toys, magnets and batteries. Most foreign body ingestions in adults occur while eating, leading to either bone or meat bolus impaction. Flexible endoscopy is the therapeutic method of choice for relieving food impaction and removing true foreign bodies with a success rate of over 95% and with minimal complications. This review describes a comprehensive approach towards patients presenting with foreign body ingestion. Recommendations are based on a review of the literature and extensive personal experience.

    We present three cases of unusual corneal/conjunctival foreign bodies that were not visible on standard slit lamp examination. All patients presented with complaints of foreign body sensation in the affected eyes. One patient had visited an ophthalmologist prior to presentation to our center and was diagnosed and treated for conjunctivitis. On slit lamp examination minimal congestion was seen hence, all the patients were diagnosed with conjunctivitis with corneal epithelial defects by the residents. However, because the patients complained of foreign body sensation, fluorescein staining of the affected eye was performed. On examination, the corneas had epithelial defects and linear scratch marks. We suspected a foreign body in upper palpebral conjunctiva (UPC). Examination after eyelid eversion indicated tripod-shaped glassy foreign bodies embedded deep within the UPC. We present cases of an unusual type of glassy tripod-shaped foreign body which may go undetected even on slit lamp examination. Fluorescein staining may aid in the detection of these foreign bodies.

    A retrospective review of 400 Chinese children who had inhaled foreign bodies was undertaken. There has been a yearly increase in the total number of cases of airway foreign bodies removed in our hospital. Fifty-eight percent of the children presenting were from the countryside; 42% were townspeople. Approximately 90% of the patients were under 3 years of age, with the peak incidence of foreign body inhalation occurring between 1 and 2 years of age (57.8%). The male-female ratio was about 1.2:1. About 95% of the removed foreign bodies were organic in origin. The majority of the foreign bodies were found most often in the right bronchial tree (46%). A positive history of foreign body inhalation was obtained in 98% of the cases. Twenty-eight percent of the children presented at the hospital within 24 hours, 71% within 1 week, and 29% more than 1 week after inhaling the foreign body. The most common presenting symptoms of laryngotracheal foreign bodies were cough, wheezing, dyspnea, and hoarseness; those of bronchial foreign bodies were cough, wheezing, decreased air entry, and rhonchi. More than two-thirds of the children with larygotracheal foreign bodies had normal x-ray findings. The most common fluoroscopic findings in those children with bronchial foreign bodies were mediastinal shift (36.8%), obstructive emphysema (35.7%), and normal findings (35%). A total of 348 (87%) bronchial foreign bodies were removed by rigid bronchoscopy (81%), rod-lens bronchoscopy (5%), and spontaneous expulsion (1%); 52 (13%) laryngeal and tracheal foreign bodies were removed by direct laryngoscopy (12%) and tracheotomy (1%). A single endoscopic procedure successfully removed 92.5% of 400 foreign bodies detected in the airways. One child died during bronchoscopy, for a mortality rate of 0.25%.

    Traumatic brainstem injuries usually lead to severe lesions and unfavourable outcome. In the literature, the few cases with favourable outcome all benefited from surgical removal of the foreign body. We report a very unusual case of a penetrating brainstem injury with a crossbow arrow with conservative treatment and favourable clinical course despite an infectious complication (brainstem abscess). This case illustrates an important gap between a good clinical status and the severity of the lesion highlighted by CT scan. In addition, a collegial decision was made not to treat the lesion surgically, but only the complication, the abscess, by stereotactic puncture. The treatment must thus be tailored in this type of lesion.

    Clinical otolaryngologists frequently encounter nasal foreign bodies (FBs) particularly among children. The removal of nasal FBs is a common otolaryngological practice. However, occasionally trauma results from FBs being lodged in the nasal cavity especially through the nasolacrimal duct. In this article we present an unusual case of a FB that from the left medial canthus went inside the nasolacrimal duct, then through the inferior turbinate and stuck in the floor of the nose. We describe the transnasal endoscopic approach used and we recommend that the treatment be done as soon as possible to avoid complications. PMID:24925531

    We present a case of confusing white foreign body in the nasal cavity detected during Endoscopic Sinus Surgery (ESS) in a 35-yr-old male which turned out to be a malposition of classic laryngeal mask airway (LMA). Although malposition of LMA is a known entity to the anesthesiologist, if ventilation is adequate, back folded LMA in nasal cavity might not be recognized by the surgeon and lead to catastrophic consequences during endoscopic sinus surgery. In principle, misfolding and malpositioning can be reduced by pre usage testing, using appropriate sizes, minimizing cuff volume, and early identification and correction of malposition.

    Paediatric age group is most vulnerable for the accidental foreign body (FB) ingestion which may go unnoticed. These patients present with symptoms or complications as a result of FB and may mimic other conditions on various investigations. We describe a 9-month old infant who ingested crystal gel ball and presented with vomiting for a month. On radiological imaging it was interpreted as duplication cyst of the duodenum. At operation, crystal gel ball was retrieved. Our case vindicates importance of keeping various possibilities in mind as differential diagnoses during evaluation and management of surgical ailments such as the duplication cyst of duodenum.

In the course of the intervention it was noted that the syndrome was determined by an acute Meckel diverticulitis, perforated by a foreign body (fish bone). In view of making the diagnosis of acute diverticulitis, that cannot be assessed before surgery, the importance is stressed of the correlation of the clinical aspects with the apendicular lesions found in the course of the operation, and, when there is no satisfactory concordance, careful checking of the cecum becomes necessary, as well as of the right annexe and of the ileon over at least three feet.

    Removal of sharp foreign bodies via upper endoscopy is common; however, management in the setting of distal migration is not well-documented. We report two cases of objects beyond the ligament of Treitz, including successful extraction of a 4.4 cm sewing pin from the cecum using hot biopsy forceps with a protector hood to shield colonic mucosa, and in a separate case, a 3.4 cm glass shard from the ascending colon using a Roth Net retriever. We demonstrate that monitoring with serial radiographs and examination may allow for supervised passage of sharp objects into the colon, where removal can be performed safely via colonoscopy.

    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.

    The Authors focus on the liability of the surgery team members in the case they inadvertently forget behind in the patient's body a foreign object, which causes injuries and/or death. The Authors underline that, according to the current case law regarding medical malpractice, both the main surgeon and their assistant/subordinate are liable for engaging in a markedly imprudent and/or negligent conduct, such as not double-checking scrupulously the surgical site before its closure in order to highlight forgotten foreign bodies. As well, the Authors underline that either the circulator nurse or the theatre nurse can be considered punishable by law when that medical error occurs, even if they are responsible for the count of the instruments used in the course of the surgery. Conversely, the main surgeon and his or her assistant are always directly responsible, due to the fact that the nurses' count procedure represents merely an additional control measure, without substituting at all the check the surgeons must obligatory conduct on the surgical site. Finally, the Authors point out that, as the count procedure is performed by the members of a surgical team, where a hierarchy-based relationship rules, the main surgeon is the liable for any preventable and avoidable adverse event provoked by the nursing staff as a consequence of the objective responsibility due to culpa in eligendo and culpa in vigilando.

Respiratory symptoms started acutely with a stridor at age 4. Thereafter she developed a chronic cough with intermittent fever. She was treated ambulatory in the health care centre with oral antibiotics and finally referred to the district hospital at age 7. The chest X-ray then suggested tuberculosis for which a 6 month treatment was given with no improvement. The cough persisted and haemoptysis appeared so the patient was referred to the reference hospital (KUTH). Chest X-ray showed diffuse lesions of the left lung with bronchiectasis. Bronchoscopy revealed the presence of a foreign body in the left intermediary bronchus and a piece of plastic was extracted. Symptoms rapidly disappeared with antibiotic treatment. This case illustrates how important it is to include foreign body inhalation in the differential diagnosis of respiratory disease in children. Bronchoscopy plays a key role in diagnosis and treatment. The authors point out the advantages of the joint efforts of the Belgian Development Aid Agency (BTC) and the Université libre de Bruxelles (ULB) in the development of this activity in the Rwandese context.

  5. Treatment of Foreign Body Obstruction of the Upper Airway

    PubMed Central

    Hoffman, Jerome R.

    1982-01-01

    The treatment of foreign body obstruction of the upper airway has been the subject of considerable attention and controversy. Current recommendations from the National Academy of Sciences, the American Red Cross and the American Heart Association include the use of back blows, abdominal thrusts (Heimlich maneuver) or chest thrusts (or both) and finger probes, until definitive therapy by trained medical and paramedical personnel becomes available. Nevertheless, a number of authorities on this subject have claimed that these approaches are dangerous, and that abdominal thrusts should be the first and only first-aid technique used in this situation. There are only limited data on which to make recommendations regarding this issue. Clinical evidence is scanty and of a highly anecdotal and unscientific nature. The data that are available suggest that a combination of maneuvers is in fact preferable to any single maneuver. Experimental physiologic data on both humans and animals tend to support this concept and suggest that back blows, which generate high initial pressures, may dislodge objects from the larynx enough to allow subsequent thrust maneuvers, which generate more sustained increases in intrathoracic pressure, to move the object out of the larynx. At this time, in the absence of definitive data, it seems reasonable to teach as many lay citizens as possible to recognize upper airway obstruction due to foreign body and to perform any and all of these techniques (preferably in combination), as well as external cardiopulmonary resuscitation (CPR) where appropriate, on choking victims.

    PubMed Central

    Lu, Guiliang; Zhou, Yu; Yu, Yao; Du, Sidan

    2011-01-01

    This paper focuses on developing a novel technique based on machine vision for detection of foreign substances in injections. Mechanical control yields spin/stop movement of injections which helps to cause relative movement between foreign substances in liquid and an ampoule bottle. Foreign substances are classified into two categories: subsiding-slowly object and subsiding-fast object. A sequence of frames are captured by a camera and used to recognize foreign substances. After image preprocessing like noise reduction and motion detection, two different methods, Moving-object Clustering (MC) and Frame Difference, are proposed to detect the two categories respectively. MC is operated to cluster subsiding-slowly foreign substances, based on the invariant features of those objects. Frame Difference is defined to calculate the difference between two frames due to the change of subsiding-fast objects. 200 ampoule samples filled with injection are tested and the experimental result indicates that the approach can detect the visible foreign substances effectively.

    2015-01-01

    Objective: To analyse the clinical efficacy of surface projection in the localization and removal of metal foreign bodies using CT scan. Methods: Total 795 cases with 1008 metal foreign bodies were treated at our hospital in 2012. Pre-operative surface projection was performed to localize foreign bodies in patients under the guidance of CT scan. The removal path from the skin surface to foreign body and puncture site were then determined. Finally, the foreign bodies were extracted using proper foreign body forceps which were chosen according to the size, depth and position of the foreign bodies in different parts of the human body. The incision length, operative time and intraoperative blood loss were recorded. Additionally, outpatient follow-up was scheduled post-operatively for 1 week. Results: The accurate localization rate under the guidance of CT scan was 100%, and 1008 pieces of metal foreign bodies were all successfully removed with a removal rate of 100%. The mean incision length was 0.4 ± 0.1 cm, the mean operative time was 4.1 ± 2.0 min and the intraoperative blood loss was 1.1 ± 0.5 ml. These results showed minimal invasiveness, shorter operative time and minimal blood loss, respectively. Additionally, the results of outpatient follow-up showed that the wound healed spontaneously. Moreover, there were no significant bleeding, incision infections or complications. Conclusion: Surface projection may be an accurate and effective method for the pre-operative localization and extraction of metal foreign bodies. Advances in knowledge: (1) Surface projection was applied for localization of metal foreign bodies in our study. (2) The accurate localization rate of surface projection under the guidance of CT scan was 100%. (3) All foreign bodies were successfully removed with a removal rate of 100%. (4) Surface projection technique has advantages in the removal of foreign bodies. PMID:26194590

    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.

    Migrating foreign bodies in the aerodigestive tract are uncommon but can pose serious complications. Long-standing migrating foreign bodies can exist manifesting chronic and unusual symptoms such as chronic cough, recurrent episodes of dyspnoea and fever. Adverse body reactions to foreign objects such as adhesions can cause difficulty in their diagnosis, localisation and removal. A thorough clinical and radiographical approach is of immense value in such cases. We report two difficult cases of migrated foreign bodies: a 2-year-old child with a long-standing foreign body that migrated to the upper mediastinum, and an adult patient with a fish bone that migrated to the oropharyngeal muscles. Presentations of these cases were not alike, with chronic unusual recurrent symptoms in one and typical acute symptoms in the other. The diagnosis and precise localisation of both foreign bodies was challenging, and an open approach was employed to remove them.

    We describe a simple and rapid method of electron probe x-ray analysis on a foreign body removed from the eye. We demonstrated the presence of copper in an intraocular foreign body which has originated from a blank 0.22 calibre cartridge. Sodium, potassium, calcium, phosphorus, sulpher and chlorine were also detected. It seems likely that these elements were derived from the biological milieu in which the intraocular foreign body had rested for some 2 years and 9 months.

    This case report highlights an unusual case where a foreign body in the parotid gland was initially thought to be sialolithiasis based on CT scans. The foreign body was safely retrieved from the parotid gland without formal superficial parotidectomy using methylene blue and an image intensifier to localize the lesion. Diagnosis and management of foreign bodies in the parotid gland are reviewed, and surgical options in removal of such lesions are discussed. PMID:23320231

    Colorectal foreign bodies per annum introduced are not exceptional. They can be classified as high-lying or low-lying, depending on their location relative to the recto-sigmoid junction. High-lying rectal foreign bodies sometimes require surgery; low-lying ones are often palpable by digital examination and can removed at bedside. No reliable data exist regarding the frequency of inserted rectal foreign bodies and the literature is largely anecdotal. We review our experience on patients almost all males and heterosexual with retained colorectal foreign bodies and their outcome in Surgical Emergency Unit of a Southern Italy University hospital.

  14. 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.

    Upper aerodigestive tract may harbour foreign bodies such as sponges, grains, toy parts, stones, paper, insects, cotton, etc. These objects may go undetected for days or even weeks. A metallic foreign body after being inhaled and ultimately being lodged in the nasopharynx is a rare entity. We report a case of an unusual nasopharyngeal foreign body (metallic bolt) presenting with symptoms of nasal regurgitation and change in voice in a 2-year boy. The foreign body was diagnosed by X-ray skull lateral view including nasopharynx and was removed under general anaesthesia.

    Abstract Self-harm is a frequent pathology amongst psychiatric patients and in the penitentiary environment. Multiple self-aggression types are described, but, by far, the practice most frequently met inside the Romanian penitentiary environment is foreign body (FB) ingestion. The paper aims to show aspects pertaining to the presence of intraduodenal foreign bodies, both in simple cases and in cases that ended with a perforation, using a number of 47 cases registered between 2003 and 2010 in “Rahova" Penitentiary Hospital. The paper also focused on particular aspects linked to intraduodenal foreign body surgical accessibility.

    The presence of foreign bodies in mushrooms affects their marketability and may result in health risks to consumers. The inspection of fresh or dried mushrooms today is very important in view of the increased consumption of this kind of food. Ten samples of dried mushrooms collected in supermarkets were examined for evidence of entomological contamination by macro and microscopic analytical methods, the so-called filth-test. A total of 49 46 determinations, comprising 15 g of the vegetable matrix, were made. The microscopic filth test consistently detected an irregular distribution of physical contaminants following repeated determinations of the same sample. Visual examination, on the other hand, was not sufficient to ensure a product free of contaminants. PMID:27800414

    Foreign body (FB) aspiration into the airway is lees common in adults than children. Nevertheless its incidence does not decrease through time. We present clinical relevant aspects of airway FBs on the basis of a selective review of pertinent literature retrieved by a search in the PubMed database. The most common aspirated FBs by adults are organics, especially fragments of bones and seeds. Symptoms usually are cough, chocking and dyspnea. Right localization, especially bronchus intermedius and right lower lobe, is more frequent. Chest radiography can be normal in up to 20% of the cases and FBs can be detected in 26% of the patients. FBs can safely remove in the majority of patients under flexible bronchoscopy. Surgical treatment must be reserved for cases in which bronchoscope fails or there are irreversible bronchial or lung complications. PMID:28066626

    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.

    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. PMID:27621882

    2016-01-01

    Although there were previous studies on the clinical aspects such as etiology, treatment modalities, studies regarding the necessity of radiologic evaluation for nasal foreign body were limited. The aim of this study is to evaluate the necessity and indication of radiologic evaluation for nasal foreign bodies. There are consecutive patients aged less than 10 years who presented with suspected foreign bodies in nasal cavity. We reviewed the patient's age and sex, including the methods of evaluation, management tools, and types of foreign bodies. There were 35 cases (11.4%) on whom radiographs were performed in the 24 uncooperative patients and 11 cooperative patients who were not identified with any foreign bodies via nasal endoscopy. Among them, only 4 cases had positive reports of foreign body and the others were normal radiologic findings. We suggest that the radiologic evaluation is always not necessary to find the location of nasal foreign bodies. It, however, should be performed in cases of negative findings of physical examination with anterior rhinoscopy or sinus endoscopy and unwitnessed foreign bodies to rule out metallic contents, especially button type battery.

    Foreign body ingestion is a common indication for imaging children. Ultrasound can be a useful adjunct to serial radiographs for evaluation of foreign bodies in the enteric tract. This case report describes a child who swallowed a single magnetic rock. Follow-up radiographs 4 days later could not determine progression of the foreign body beyond the stomach. Ultrasound was used to locate it, showing a structure with unexpected posterior reverberation artifact in the stomach. This was correlated with a similar magnet in a water bath demonstrating identical reverberation artifact. This report discusses the underlying factors for the different sonographic appearances and associated ultrasound artifacts of foreign bodies. This knowledge is important when performing sonography as adjunct modality for identification of foreign bodies in the gastrointestinal tract.

    Background Guidelines support endoscopic removal of certain gastric FB and all FB lodged in the esophagus. We aim to report our experience on endoscopic foreign bodies (FB) removal in order to aid in the formation of future guidelines regarding this subject. Methods Retrospective analysis of one hundred forty-four cases of FB removal involving 43 patients who underwent esophagogastroduodenoscopy (EGD) for FB removal from January 2005 through December 2010 in a university-based hospital. To evaluate to outcome of endoscopic FB removal, cost of procedures and complications. Results Of all FB removal cases, 23 (53%) were males, with total mean age of 26.4 ± 11.3 years. Only 20% were performed on an outpatient bases. Abdominal x-ray was obtained to confirm ingestion of FB in 83%, and computed tomography scan was performed in 13%. Most procedures were performed in operation room (59%) while only 21% of the cases were performed in endoscopy lab. General anesthesia was used in 58%, while monitored anesthesia care in 28%. Average time to EGD was 17.14 hours. No major complications due to procedure were reported. Minor trauma and erosions due to FB were reported in 14%. FB extraction was unsuccessful in only three cases, and one case required surgical intervention. Cost of all procedures was over 430, 000 dollars with mean of 2,990 dollars for procedure. Conclusion Endoscopic retrieval is effective and safe procedure, but utilizes significant hospital resources. PMID:27785219

  7. Stability Analysis of a Model for Foreign Body Fibrotic Reactions

    2012-01-01

    Implanted medical devices often trigger immunological and inflammatory reactions from surrounding tissues. The foreign body-mediated tissue responses may result in varying degrees of fibrotic tissue formation. There is an intensive research interest in the area of wound healing modeling, and quantitative methods are proposed to systematically study the behavior of this complex system of multiple cells, proteins, and enzymes. This paper introduces a kinetics-based model for analyzing reactions of various cells/proteins and biochemical processes as well as their transient behavior during the implant healing in 2-dimensional space. In particular, we provide a detailed modeling study of different roles of macrophages (MΦ) and their effects on fibrotic reactions. The main mathematical result indicates that the stability of the inflamed steady state depends primarily on the reaction dynamics of the system. However, if the said equilibrium is unstable by its reaction-only system, the spatial diffusion and chemotactic effects can help to stabilize when the model is dominated by classical and regulatory macrophages over the inflammatory macrophages. The mathematical proof and counter examples are given for these conclusions. PMID:23193430

    Aspiration of foreign bodies (FBs) by children can lead to serious illness and sometimes even death. Bronchoscopic removal of the FB is necessary to prevent from any catastrophic event. Sometimes bronchoscopic removal is not possible due to the larger size of the FB, sharp FB, or long duration FB. Tracheostomy is normally used for the removal of such FBs. The aim of this case report is to highlight the use of Heimlich maneuver for the removal of such FBs before opting invasive procedures. In the present case, a 5-year-old child was presented with history of FB aspiration 5 h back. After multiple failed bronchoscopic attempts to remove the FB it was decided to use Heimlich maneuver in the supine position. A single attempt of Heimlich maneuver expelled the FB into the oral cavity, which was removed by Magill's forceps. On repeated bronchoscope check, there was no remnant of FB. Child's further course of stay in hospital was uneventful. In conclusion, Heimlich maneuver may be useful in patient with failed bronchoscope removal of airway FBs before proceeding for tracheotomy or other invasive procedures.

    2017-01-06

    Medical and lay attention to and intervention for rectal foreign bodies, the presence of an object in the rectum most often via insertion through the anus, has long been a source of humour and suspicion in both medical and public discourses. How do the ways medical providers write and talk to each other about rectal foreign bodies shape and reflect understandings of gender, sexuality and the (im)proper use of the anus and rectum? This paper examines the medical literature on rectal foreign bodies to shed light on the ways in which medical providers frame rectal foreign bodies. It develops a set of six frames that demonstrate how the medical literature on rectal foreign bodies (re)produces a variety of normative assumptions about and sociocultural values concerning bodies and sexuality, danger, shame, deception, mental illness and medical professionalism. It concludes with a discussion of how these framings of rectal foreign bodies might potentially contribute to the ongoing stigmatisation not only of rectal foreign body patients, but of non-heteronormative sexualities in general.

    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

    Vaginal discharge in prepubertal children is mainly due to hypoestrogenic state of vaginal mucosa making it thin and alkaline leading to mucosal invasion by pathogen. In a paediatric case with persistent foul smelling , blood stained vaginal discharge not responding to medical therapy, vaginal foreign body should always be ruled out. Here, we report a 3 -year -old girl with complaint of recurrent vaginal discharge occasionally blood stained not relieved despite few antibiotics courses. On X -ray pelvis, a radioopaque foreign body hair clip was seen. Under sedation foreign body was removed by forceps following which child became asymptomatic. PMID:25738041

    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.

Evisceration was performed. There were no cardiopulmonary and gastroenterological findings except mild bradycardia (54/min). CT evaluation revealed a 4-cm-sized, sharp, metallic, intraorbital foreign body in the left orbit. After the removal of the foreign body, the symptoms completely resolved with a normal heart rate (69/min). The authors present a case of delayed oculocardiac reflex induced by an old intraorbital foreign body.

    We present a case of foreign body synovitis in the knee joint caused by a fragment of stainless steel imbedded in the tibial plateau for 10 years, which was extracted successfully using an arthroscope. The cause of synovitis was the long-standing release of small stainless steel particles resulting from the abrasion of the steel against the opposing lateral femoral condyle. For an articular foreign body, arthroscopy is by far the best treatment. Arthroscopy allows the surgeon to localize as well as to extract even the smallest foreign body fragment, and also provides for washing out of the joint cavity.

    2015-01-01

    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.

    Schwannoma is usually a subcutaneous benign neoplasm that derives from nerve sheath. Pain and neurologic symptoms are uncommon, and exclusively dermal tumors are very rare. Solitary schwannoma has a traumatic origin in some cases, and rarely occur as a part of neurofibromatosis or schwannomatosis. An association of deeply located schwannoma with foreign material has been reported in very few cases. To our knowledge, we present the first case of a painful dermal schwannoma in association to foreign material.

    Foreign bodies in paranasal sinuses are very rare and most of them are encountered in the maxillary sinus. These foreign bodies may be organic or inorganic and can enter the maxillary sinus through an oro-antral fistula. The oro-antral fistula is formed by a break in the bony segment of the maxillary sinus floor and usually arises subsequent to maxillary premolar and molar extractions. A 63-year-old female patient evaluated for a nonhealing, left, toothless palate lesion and chronic headache occurring over 4 years. Radiography and computed tomography revealed bone discontinuity in the left floor of the maxillary sinus and calcifications within the antrum. A blue foreign body, later identified as dental impression material, was removed by intranasal endoscopy. A careful oral examination is recommended prior to prosthetic restorations. In addition, paranasal sinus foreign bodies should be surgically removed to prevent secondary soft tissue reactions.

    The topic of foreign body ingestion has received extensive coverage in the areas of surgery, emergency medicine, and pediatrics. A subset of this topic, the intentional ingestion of foreign bodies, however, is much less common, and requires special evaluation and management. Here, we report a case of ingestion of a rolled, metal tuna can lid in a male prison inmate previously diagnosed with depression and paranoid schizophrenia. Following evaluation by the surgical team, the foreign body was removed by laparotomy and the patient was discharged back to the prison without complication. In many cases, ingestions of this type involve a command hallucination ordering the patient to swallow the foreign body. Interestingly, the patient in the present case reported auditory hallucinations commanding him not to swallow the can lid. On further investigation, we found that patient had a proclivity toward this swallowing behavior even prior to his incarceration. Early identification of inmates with this proclivity has important implications for treatment and prevention.

    Imaging in traumatic injury to the orbits plays an important role to identify malformation of the globe, retrobulbar pathology, such as hematoma, the presence of fractures, and identification of foreign bodies. MRI can be especially useful in characterizing soft tissue abnormalities without the use of ionizing radiation. The authors report a case of penetrating injury to the orbit with a retained foreign body where the graphite core of a pencil ("pencil lead") resulted in metal-like diamagnetic susceptibility artifact. This was proven to have no metallic components by CT and surgical exploration. MRI performed in the setting of penetrating injury could aid in localization of a graphite foreign body, and if there is a known graphite foreign body, evaluation of immediately adjacent structures may be obscured.

    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.

    Foreign bodies in esophagus are avoidable accidents that occur most often in children younger than 3 years. The most common presenting symptoms are dysphagia, drooling and vomiting. Occasionally a foreign body in the esophagus may present with respiratory symptoms such as cough, stridor and respiratory distress. This is more common in young children and when the object remains lodged in the esophagus for a prolonged period. Clinical suspicion is essential for early diagnosis, which allows to avoid potential complications. We describe 3 children with a foreign body impacted in the esophagus who presented mainly respiratory symptoms. We alert pediatricians on symptomatic variation in the presentation of a foreign body ingestion and we underline the importance of early diagnosis and treatment.

    Aspiration of foreign bodies is an important and preventable cause of morbidity and mortality in childhood. The early diagnosis and treatment are essential for risk of mortality in the acute and complications arising from the continuance of a foreign body in the airway. The clinical presentation may mimic different diseases, delaying the correct diagnosis. Pediatricians should be aware of the possibility of foreign body in children with persistent respiratory symptoms, even in the absence of a history of choking. Bronchoscopy is indicated in all patients with suspected aspiration, even when the physical and radiological examination is inconclusive. We evaluate in 90 cases the time between the aspiration of foreign body and the removal, and emphasize the need for preventive measures and greater dissemination of knowledge in the community and health professionals about this problem.

    Foreign body ingestion is a common clinical problem in early childhood. However, it may occur even in adults, unknowingly. Most ingested foreign bodies entering the stomach pass through the gastrointestinal tract uneventfully. Here we report on a 13-year-old boy who presented with chronic abdominal pain, weight loss and occult gastrointestinal bleeding for 6 mo. Colonoscopy was negative; however, a ballpoint pen was impacted in the sigmoid region. Subsequently, the child admitted swallowing a pen as a 20-euro bet 6 mo previously. Crohn's disease is a chronic relapsing inflammatory gastrointestinal disease. It is often difficult to diagnose due to the fact that there is no single pathognomonic sign or symptom. This case is a description of an adolescent with chronic gastrointestinal symptoms due to a foreign body. Therefore, an ingested foreign body should be included in the differential diagnostic procedure related to gastrointestinal symptoms.

    Fishbones are the most commonly ingested foreign bodies that cause gastrointestinal tract penetration. However, fishbones embedded in the gastrointestinal tract that lead to foreign body granulomas that mimic submucosal tumors are rare. Herein, we describe a 56-year-old woman who presented with a 20-day-history of upper abdominal pain. Endoscopy revealed an elevated lesion in the gastric antrum. An abdominal computed tomography scan showed a mass in the gastric antrum and a linear calcified lesion in the mass. An endoscopic ultrasonography examination revealed a 3.9 cm × 2.2 cm, irregular, hypoechoic mass with indistinct margins in the muscularis propria layer. The patient was initially diagnosed as having a submucosal tumor, and subsequent surgical resection showed that the lesion was a foreign body granuloma caused by an embedded fishbone. Our case indicated that the differential diagnosis of a foreign body granuloma should be considered in cases of elevated lesions in the gastrointestinal tract.

    A patient was found to have a metallic foreign body in the left anterior orbit on CT imaging, but the foreign body was not evident on clinical examination. On high-resolution ultrasonography, an object was identified in the left upper eyelid; however, the typical shadow with metallic foreign bodies was not seen. A high-power oscillating magnet was then applied to the eyelid, which revealed a subcutaneous metallic foreign body in the left upper eyelid. When used in conjunction, the high-resolution ultrasound and oscillating magnet successfully localized and facilitated retrieval of the metallic foreign body from the left upper eyelid.

    Missed or neglected foreign bodies are not infrequent in surgical practice. This case report highlights the fact that thorough clinical examination and detailed evaluation of trauma patients are very necessary so that any associated injuries or foreign bodies will not be missed and any unforeseen clinical or medico-legal complications can be prevented. We present a case of a 35-year- old male patient who had traumatic transfemoral amputation of the right lower limb with a clean laceration (size 2 cm multiply 1 cm) over the medial aspect of the left thigh. Radiographs suggested a single radioopaque foreign body which proved misleading, as during surgical removal multiple radiolucent and radiopaque foreign bodies were discovered. Postoperative ultrasound was performed and showed no retained foreign bodies. A secondary closure of the right thigh amputation was done and patient was discharged. At the last follow-up, 9 months after injury, the patient had no complaints, and both the amputation stump and the wound over the left thigh were healthy. Thus in the cases of retained foreign bodies, in addition to thorough clinical examination and radiography, ultrasonograpy should be supplemented. And if required, use of CT scan as well as MRI should be also considered.

    2016-01-01

    Foreign body ingestion is a common diagnosis that presents in emergency departments throughout the world. Distinct foreign bodies predispose to particular locations of impaction in the gastrointestinal tract, commonly meat boluses in the esophagus above a preexisting esophageal stricture or ring in adults and coins in children. Several other groups are at high risk of foreign body impaction, mentally handicapped individuals or those with psychiatric illness, abusers of drugs or alcohol, and the geriatric population. Patients with foreign body ingestion typically present with odynophagia, dysphagia, sensation of having an object stuck, chest pain, and nausea/vomiting. The majority of foreign bodies pass through the digestive system spontaneously without causing any harm, symptoms, or necessitating any further intervention. A well-documented clinical history and thorough physical exam is critical in making the diagnosis, if additional modalities are needed, a CT scan and diagnostic endoscopy are generally the preferred modalities. Various tools can be used to remove foreign bodies, and endoscopic treatment is safe and effective if performed by a skilled endoscopist. PMID:27807447

    Paranasal sinus injuries by foreign bodies have a lower incidence compared with facial injuries. Among them, penetrating maxillofacial injuries to the sphenoid sinus and skull base remain rare. We report the case of a 41-year-old man who presented with, after a missile-related maxillofacial injury, a metallic foreign body enclosed within the sphenoid sinus with carotid-canal fracture. Angiographic evaluation showed a mass in the right internal carotid artery. The foreign object was successfully extracted through a transmaxillary sublabial approach with a good outcome. We discuss the extensive preoperative evaluation and interdisciplinary management of this unusual injury.

    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

    Purpose. Ocular trauma with retained foreign body is an important cause of visual impairment in working-age population. Clinical status impacts on the timing and planning of surgery. In the last year small gauge vitrectomy has become safer and more efficient, extending the range of pathologies successfully treated. Aims. To evaluate the safety and outcomes in patients with open eye injury with retained foreign body that underwent early 25-gauge vitrectomy. Methods. In this retrospective, noncomparative, interventional case series, we performed 25-gauge vitrectomy on 10 patients affected by open globe injuries with retained foreign body, over 3 years. We analyzed age, wound site, foreign body characteristics, ocular lesions correlated, relative afferent pupillary defect, visual acuity, and intraocular pressure. Follow-up evaluations were performed at 1, 3, and 6 months. According to the clinical status we performed other procedures to manage ocular correlated lesions. Results. The median age of patients was 37 years. The foreign body median size was 3.5 mm (size range, 1 to 10 mm). 25-gauge vitrectomy was performed within 12 hours of trauma. Foreign body removal occurred via a clear corneal or scleral tunnel incision or linear pars plana scleral access. Visual acuity improved in all patients. Endophthalmitis was never reported. Only two cases reported postoperative ocular hypertension resolved within the follow-up. Retinal detachment recurred in one case only. Conclusions. 25-gauge vitrectomy could be considered as early approach to manage open globe injuries with a retained posterior segment foreign body in selected cases with good outcomes and low complication rate.

    Purpose To analyze the clinical features of foreign-body aspiration into the lower airway in geriatric patients. Patients and methods The clinical data of 17 geriatric patients with foreign-body aspiration were retrospectively analyzed and compared with 26 nongeriatric adult patients. The data were collected from Peking University First Hospital and Anhui Chest Hospital between January 2000 and June 2014. Results (1) In the geriatric group, the most common symptoms were cough and sputum (15 cases, 88%), dyspnea (six cases, 35%), and hemoptysis (four cases, 24%). Five patients (29%) in the geriatric group could supply the history of aspiration on their first visit to doctor, a smaller percentage than in the nongeriatric group (13 cases, 50%). Only three cases in the geriatric group were diagnosed definitely without delay. Another 14 cases were misdiagnosed as pneumonia or lung cancer, and the time of delayed diagnosis ranged from 1 month to 3 years. Complications due to delay in diagnosis included obstructive pneumonitis, atelectasis, lung abscess, and pleural effusion. (2) Chest computed tomography demonstrated the foreign body in three cases (21%) in the geriatric group, which was lower than the positive proportion of detection in the nongeriatric group (nine cases, 35%). The most common type of foreign body in the geriatric group was food, such as bone fragments (seven cases, 41%) and plants (seven cases, 41%), and the foreign body was most often lodged in the right bronchus tree (eleven cases, 65%), especially the right lower bronchus (seven cases, 41%). Flexible bronchoscopy removed the foreign body successfully in all patients. Conclusion The clinical features of foreign-body aspiration in geriatric patients are usually more obscure than in nongeriatric adults, which may lead to long delay in diagnosis. Flexible bronchoscopy is safe and useful for early diagnosis and effective management in geriatric patients. We suggest flexible bronchoscopy as the first

    A number of people injured during the second world war harbour foreign bodies such as grenade splinters or bullets in some part of the body. Most of these metal fragments remain clinically silent. Some of them, however, may cause delayed complications. The purpose of this study was to determine the characteristics of delayed complications associated with foreign bodies after world war II injuries. 159 patients with retained foreign bodies after world war II injuries were retrospectively identified radiologically in our data bases in the time interval from 1997 to 2009. Diverse delayed complications secondary to the metal objects were diagnosed in 3 cases (2%): one patient with grenade splinter migration into the choledochal duct, one case with pseudotumoural tissue reaction, and one patient with late osteomyelitis. The time from injury to clinical presentation varied from 56 to 61 years. PubMed and Medline were screened for additional cases with delayed sequelae after foreign body acquisition during the 2nd world war. A 30 year search period from 1980 up to date was selected. 15 cases were identified here. Our study demonstrates that health consequences of the 2nd world war extend into the present time, and therefore physicians should be aware of the presence of hidden foreign bodies and their different possible late reactions.

    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.

    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.

    A 26-year-old Turkish Army soldier underwent full ophthalmoscopic examination after a penetrating ocular injury in the left eye due to the accidental explosion of a detonating fuse during handling. Visual acuity of the left eye was hand motion level. Funduscopy revealed foreign bodies suspended in the vitreous gel and accompanying vitreous haemorrhage. B-scan ultrasonography, CT of the orbits and microscopic examination of the intraocular foreign bodies (IOFBs) were performed prior to removal of bone fragments and pars plana vitrectomy. The IOFBs were fragments of the patients' bone tissue. Bone fragments from victim's body may cause IOFBs after an explosion in military personnel.

    Aspiration of tracheobronchial foreign bodies commonly affects young children, is potentially life threatening and requires early intervention for extraction. Access to facilities and skill manpower for bronchoscopic extraction is however limited in Nigeria. The aim of this study is to describe the experience in our institution with bronchoscopic removal of tracheobronchial foreign bodies and highlight the challenges encountered. This is a retrospective study of all patients referred to the Lagos State University Teaching Hospital with a diagnosis of tracheobronchial foreign body within the period of February 2008 and February 2013. Data extracted from the medical records were age, sex, time interval between aspiration and presentation, location of tracheobronchial foreign body, bronchoscopic technique, complications and outcome. A total of 24 patients were referred and confirmed at bronchoscopy to have tracheobronchial foreign bodies. Mean age was 6.6 + 5 years. Male to female ratio was 1:1. Delayed presentation was common with 22 patients (91.7%) presenting more than 24 hours after aspiration. Aspirated material was inorganic in 17 patients (70.8%) and organic in 7 patients (29.2%). Location of tracheobronchial foreign bodies was right main bronchus in 16 patients (66.7%), left main bronchus in 6 patients (25%) and the trachea in 2 patients (8.3%). Challenges to speedy and safe removal of the foreign bodies were delayed presentation and a limited range of bronchoscopic equipment early in the series which caused prolonged procedures and increased complications. Two mortalities occurred early in the series; one from airway obstruction and the other from respiratory failure caused by tracheobronchial oedema. Extraction of tracheobronchial foreign bodies was faster, more complete and safer later in the series due to a wider range of bronchoscopy equipment which included both flexible and rigid videobronchoscopy with the use of optical forceps.

    Foreign body reactions may occur in patients who receive bioabsorbable implants during orthopedic surgery for fractures and ligament repair. The authors describe a 34-year-old man who presented with a palpable tender mass on the lateral aspect of the left knee of 1 month's duration. He underwent posterior cruciate ligament and posterolateral corner reconstruction 3 years earlier. Physical examination showed a 1×1-cm soft, nontender mass without localized warmth on the lateral epicondyle of the distal femur. Magnetic resonance imaging showed a broken screw fragment surrounded by a cyst-like mass. Under general anesthesia, the surgeon excised the screw fragment and the fibrotic mass, enclosing it in the subcutaneous tissue at the lateral epicondyle, the site at which a poly-L-lactic acid bioabsorbable screw had been inserted to fix the graft for posterolateral corner reconstruction. Histologic evaluation showed a foreign body reaction to the degraded screw particles. To the authors' knowledge, this report is the first description of a patient presenting with a delayed foreign body reaction to a broken poly-L-lactic acid bioabsorbable screw at the lateral femoral epicondyle after posterolateral corner reconstruction. Because delayed foreign body reactions can occur at any site of poly-L-lactic acid bioabsorbable screw insertion, care should be taken to avoid screw protrusion during ligament reconstruction because it can lead to screw breakage and delayed foreign body reaction.

    Oesophageal foreign bodies are common in dogs. Endoscopic removal is a viable treatment option but few studies have assessed the clinical and radiographic features that would be useful in decision-making and prognosis. Dogs (n = 44) with oesophageal foreign bodies presented to the University Veterinary Hospital were assessed. Terriers and West Highland White Terriers were significantly overrepresented (p < 0.0001) and in those breeds the foreign body was significantly (p < 0.0001) more likely to be located caudal to the heart base. The majority (88.6%) of foreign bodies were bones or bone fragments. Group 1 (n = 30) included animals where endoscopic removal was successful and Group 2 (n = 14) animals where it was unsuccessful or not attempted because of evidence of oesophageal rupture. There was no statistically significant difference in age, sex, body weight, type, location and size of foreign body, recovery rate, short-term complications and long-term outcome between the two groups. Duration of signs prior to presentation and time to spontaneous oral feeding were significantly longer (p < 0.01 in each case) in Group 2 (five days and 120 hours, respectively) compared to Group 1 (2 days and 24 hours, respectively). Mortality was 11.1%. Long-term follow-up of 29 dogs suggested oesophageal stricture formation manageable by feeding alone in seven (24.1%) cases. Terriers appear predisposed to oesophageal foreign bodies. Success of endoscopic removal is adversely affected by duration of signs prior to presentation. Surgical removal negatively influences time to recovery. Stricture formation appears to be a relatively common complication and alternate measures for its prevention should be sought. PMID:21851744

    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.

  16. Pitfalls in diagnosis and problems in extraction of retained wooden foreign bodies in the foot.

    The detection and removal of a radiolucent foreign body in soft tissues is a problem. It is further complicated when it is not radio-opaque and embedded in the deep layers of the foot. Despite advances in imaging techniques, the detection of retained wooden foreign bodies remains a difficult and challenging task. Although radiographs have been proven to be ineffective, it is often the first method used. Wood often splinters, causing incomplete removal and persistent symptoms. In such cases complete surgical extraction cannot be guaranteed in spite of our best efforts. Therefore, a post-procedure imaging to ensure the adequacy of extraction becomes crucial. The choice of imaging in such circumstances is a moot point to consider. This case report highlights the common pitfalls associated with retained wooden foreign bodies and demonstrates how ultrasonography could be used as a simple and effective tool in this regard.

The symptomatology, physical, laboratory and x-ray findings are described. Methods of management are discussed, with emphasis on the operative management of perforations and the conservative approach to retained foreign bodies. It is felt that these protocols will be useful to physicians who see this practice less frequently. X-rays of two more unusual cases are depicted. A thorough review of the literature is also presented. This is the largest reported series of patients with retained rectal foreign bodies and/or perforations. The series includes two female patients, a heretofore unreported occurrence. Images Fig. 1. Fig. 2. PMID:984928

    Intraorbital foreign bodies are located within the orbit but outside the ocular globe. Though not uncommon, removal of these objects poses a challenge for surgeons. External approaches have been the most frequently used but are associated with increased complications and morbidity. An endoscopic endonasal approach can be an appropriate and less complicated technique in these cases. We report a case of a chronic intraorbital foreign body located within the medial extraconal space lateral to the lamina papyracea and behind the lacrimonasal duct, which was successfully removed using a transnasal, transethmoidal endoscopic technique. Neither postoperative complications nor ocular impairment was reported. The patient improved and remains asymptomatic. The transnasal transethmoidal endoscopic approach can be used as a safer and less invasive alternative when removing foreign bodies from the medial orbital compartment. PMID:27957368

    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

A detailed case report was made of the use of anterior segment OCT (AS-OCT) and ocular Pentacam to evaluate intrastromal foreign bodies. AS-OCT and Pentacam were valuable non-invasive tools in identification, localization and monitoring patients with intrastromal foreign bodies. This report demonstrates that AS-OCT and ocular Pentacam are effective and necessary procedures for both the diagnosis and follow-up of intracorneal foreign bodies.

    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.

    A woman with bilateral breast cancer treated with bilateral mastectomies, implant reconstructions, chemotherapy, and hormonal therapy underwent FDG PET/CT imaging. Imaging demonstrated sternal, nodal, and lung lesions which were stable or slowly increasing, as well as a parasternal chest wall mass which was enlarging much more rapidly and was excised. Pathology of the chest wall mass demonstrated only benign soft tissue with fat necrosis and foreign body giant cell reaction, without evidence of malignancy or implant rupture. This case demonstrates how a benign FDG-avid foreign body reaction, induced by an intact breast prosthesis, could easily be mistaken for malignancy.

    Introduction For Otorhinolaryngologist, removal of Foreign Bodies (FB) from the ear, nose and throat is one of the common emergency procedures done. Most of the cases especially of the ear and nose can be managed without General Anaesthesia (GA). But in some cases GA may be needed. There are very few studies that address the scenario of ear, nose and throat foreign body that required GA for its removal and the complications associated with it. Aim This study was conducted with the aim to study the patient’s profile, types and distribution of FB removed under GA, and the associated complications. Materials and Methods The present study is a hospital based retrospective, cross-sectional study conducted in the Department of Otorhinolaryngology in association with Department of Anaesthesiology and Critical Care in North Eastern Indira Gandhi Regional Institute of Health and Medical Sciences, Shillong, Meghalaya, India from year 2009 to 2014. Information was collected from indoor patient file and operation record book. Those patients where foreign body was not found after examination under GA were excluded. Results A total of 112 cases of foreign body in ear, nose and throat removed under GA were selected. There was variation of age from youngest case being 11 months to 74 years with a slight male predominance. Two third of the patients belonged to paediatric age group. Most of the FB were inanimate with high number of inorganic type found in majority. Foreign body in food passage was found in most cases. Coin and meat bone were the common FB in children and adults respectively. We found no complications related to removal of foreign body from the food passage and nose. But some complications were seen in foreign body of ear and tracheo-bronchial tree. Conclusion Ear, nose and throat FB that required GA were seen in all age groups. FB of food passage constitute the majority. Type of foreign body varies between children and adults. In children most common types were

    Foreign bodies in the noses of children may often be expelled by simple nose blowing. Success of this manoeuvre depends on how firmly the object is lodged, and on the co-operation and skill of the child. Attempts at direct removal using instruments frequently result in the patient becoming distressed and resort to general anaesthesia is sometimes required. This short communication describes a series of cases in which nebulized adrenaline helped loosen firmly impacted foreign bodies, thereby facilitating removal, minimizing upset for the child, and avoiding anaesthetic risk.

    Fibroendoscopy is the treatment of choice for foreign oesophageal and gastric bodies. Whereas the presence of objects in the oesophagus demands immediate endoscopic removal, gastric localization does not require any emergency treatment except for cases of perforation or incarceration, as most foreign bodies (80-90%) are eliminated naturally. Only two weeks after ingestion, in the case of failed expulsion, is it necessary to proceed to endoscopic removal so as to prevent decubitus or perforation erosions. Endoscopic extraction is made difficult by the length and weight of the object, on by its smallness and lack of texture, which make it hard to get hold of. In the case of suture stitches, it may be hard to cut them because of the presence of a gastric mucosa reactive granulomatous inflammatory process. Contraindications to endoscopic extraction are the failure of the patient to cooperate, acute oesophagitis (peptic and due to caustics) and perforating in the stomach, due to congenital or acquired malformations, means that surgery is necessary. The elimination of foreign bodies depends on the correlation between shape and size of object and the anatomo-functional components of the digestive ways. With reference to an approximate geometric schematization of transit organs, the physiopathology of foreign bodies may be expressed by means of mathematical formulae whose manifold variables sometimes make the natural elimination of the bodies unpredictable.

    Tissue engineering chamber technique can be used to generate engineered adipose tissue, showing the potential for the reconstruction of soft tissue defects. However, the consequent foreign body reaction induced by the exogenous chamber implantation causes thick capsule formation on the surface of the adipose flap following capsule contracture, which may limit the internal tissue expansion. The nanotopographical property and architecture of nanofibrous scaffold may serve as a promising method for minimizing the foreign body reaction. Accordingly, electrospinning porous polycaprolactone (PCL) nanofibrous mesh, a biocompatible synthetic polymer, was attached to the internal surface of the chamber for the reducing local foreign body reaction. Adipose flap volume, level of inflammation, collagen quantification, capsule thickness, and adipose tissue-specific gene expression in chamber after implantation were evaluated at different time points. The in vivo study revealed that the engineered adipose flaps in the PCL group had a structure similar to that in the controls and normal adipose tissue structure but with a larger flap volume. Interleukin (IL)-1β, IL-6, and transforming growth factor-β expression decreased significantly in the PCL group compared with the control. Moreover, the control group had much more collagen deposition and thicker capsule than that observed in the PCL group. These results indicate that the unique nanotopographical effect of electrospinning PCL nanofiber can reduce foreign body reaction in a tissue engineering chamber, which maybe a promising new method for generating a larger volume of mature, vascularized, and stable adipose tissue.

Patients with this problem who sought treatment in the otorhinolaryngology clinic of Hospital Universiti Sains Malaysia (HUSM) were studied for duration of one year from January 2010 to December 2010. Specifically, the clinical presentation, type of foreign body and management outcome were analysed. 72 patients were reviewed - 44 (61.1%) males and 28 (38.9%) females. The age range was one year to 75 years with 59.8% being children below 10 years old. Ear pain (56.9%) was recorded as the most common and persistent symptom and insects (54%) were the commonest foreign body encountered. 95% (69) of the foreign bodies were removed under clinic setting with only three (4.2%) cases requiring general anaesthesia. Post-removal complications were noted in only one patient (1.4%). Repeated attempts by untrained personnel should be avoided and timely referral is vital to avoid undesirable complications.

    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.

    Seven patients were treated during a period of three years in the Otolaryngology department of Tel-Aviv Medical Centre, Israel, for the ingestion of a strange, previously unknown foreign body. The objects had been inadvertently swallowed while eating certain dairy products such as yogurt or sour cream. This rigid, sharp pointed plastic object is a waste product which is punched out from the production line of the foods and their containers. The plastic object is radiolucent and, therefore, difficult to identify on standard roentgenograms. Fluoroscopic examination with a contrast medium was needed for its demonstration. Five patients underwent rigid esophagoscopy under general anesthesia for removal of the foreign body. In two other cases the object was extracted from the piriform sinus under topical anesthesia. This unusual foreign body, although uncommon, poses a potential medical hazard. A high index of suspicion is necessary to make the diagnosis when a patient presents with a history of foreign body ingestion while eating dairy products of soft consistency.

    We evaluated the role of the emergency department (ED) in the management of ear, nose, and throat foreign bodies in an Australian tertiary care hospital. We retrospectively reviewed all cases of ENT foreign-body presentations in the ED over a 2-year period. We identified 168 such cases, a large proportion of which involved pediatric patients. In addition to demographic factors, we also collected data on the nature of the foreign bodies, the specific sites involved, the rate of successful treatment by the ED staff, the seniority/rank of the treating clinician, and complications. Foreign bodies in the ear accounted for 49% of all cases, the nose for 43%, and the throat for 8%. The ED staff attempted to remove the foreign body in 89% of cases, while the rest were referred to the ENT team. The rate of successful removal of all foreign bodies attempted by the ED team was fairly high-78%; success rates were 86% for nasal foreign bodies, 72% for aural objects, and 67% for those lodged in the throat. No major complications occurred; minor bleeding episodes after removal occurred in 8% of cases. Most ENT foreign-body presentations were managed safely and entirely by the ED team; most of the ENT referrals were to outpatient clinics.

    Fish bones as a foreign body are often present in the palatine tonsil and the base of the tongue. Such foreign bodies can often be diagnosed with inspection only. However, it is difficult to diagnose and extirpate a foreign body when it is buried in the oral/pharyngeal mucosa. We experienced a case of a fish bone foreign body buried in the tongue muscle layer. We report herein on the case of a 49-year-old man with a fish bone foreign body buried in his tongue. The patient had noticed a sore throat since eating a sea bream and was referred to our department. Visual inspection revealed no foreign body, but CT imaging revealed a fish bone in the tongue. We performed an emergency surgical exploration of tongue to locate the fish bone. Because the fish bone as a foreign body was unable to be confirmed by palpation, we identified the location of the fish bone by intraoperative CT. This is a rare case of a fish bone buried in the tongue muscle layer, and intraoperative CT was useful in identifying the positon of the foreign body.

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.

    A fuel injection array for a gas turbine engine includes a plurality of bluff body injectors and a plurality of swirler injectors. A control operates the plurality of bluff body injectors and swirler injectors such that bluff body injectors are utilized without all of the swirler injectors at least at low power operation. The swirler injectors are utilized at higher power operation.

    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.

    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.

    A foreign body granuloma of the buccal mucosa induced by honeybee sting was reported. The patient was an 82-year-old female who presented with a submucous mass at the right buccal mucosa. The mass was 20 mm in diameter, elastically firm, partly mobile without pain or tenderness, and covered with almost normal mucosa. MR image did not delineate the lesion clearly. Under clinical diagnosis of a benign tumor, the lesion was excised under local anesthesia. The excised lesion was 14 × 11 × 9 mm in size and solid and yellowish in cut surface. Histologically, the lesion consisted of granulomatous tissue with a few narrow, curved, eosinophilic structures compatible with decomposed fragments of a honeybee sting and was diagnosed as a foreign body granuloma, although the patient did not recall being stung.

    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.

    Retained foreign bodies after surgery have the potential to cause serious medical complications for patients and bring fourth serious medico-legal consequences for surgeons and hospitals. Standard operating room protocols have been adopted to reduce the occurrence of the most common retained foreign bodies. Despite these precautions, radiolucent objects and uncounted components/pieces of instruments are at risk to be retained in the surgical wound. We report the unusual case of a retained plastic pulsatile lavage irrigator tip in the surgical wound during acetabulum fracture fixation, which was subsequently identified on routine postoperative computed tomography. Revision surgery was required in order to remove the retained object, and the patient had no further complications. PMID:21619681

    Purpose: The purpose of this study is to describe a case series of keratoconjunctivitis caused by a retained bindi (dot) in six children who presented to a tertiary eye care facility in Southern India. Patients and Methods: Over a period of 11 years (January 2000 and January 2012), six children (all female, ranging in age from 6 months to 3 years) were diagnosed with ocular manifestations subsequent to a retained bindi. Results: All patients presented with redness, photophobia, extensive lacrimation, and blepharospasm. Two patients presented with mucopurulent conjunctivitis, three patients with suppurative keratitis and one patient presented with corneal epithelial defect. After removal of the foreign body the response to topical antibiotics was good in five of six cases, whereas one patient required therapeutic keratoplasty. Conclusions: Young children presenting with unilateral keratitis and conjunctivitis should alert the clinician to the possibility of a retained foreign body in the eye. PMID:24881616

    A foreign body lodged for decades in the parotid gland, entering through the oral cavity or the skin, is extremely rare. Even less common is the clinical presentation of a foreign body lodged in the parotid gland simulating a tumour. The authors report the finding of a fragment of shrapnel lodged in the parotid gland for 63 years. The case is unusual owing to the rare clinical presentation, the length of time between the injury and the occurrence of symptoms and the associated mandibular osteolysis in the panoramic radiograph. Initial diagnoses considered were a tumour emerging in the parotid gland, a large odontogenic cyst or an odontogenic tumour with soft tissue extension. Sometimes neither fine needle aspiration nor radiology is capable of providing an accurate diagnosis before surgery.

    2014-12-22

    Chest X-ray in a 17-year-old boy, presenting with haemoptysis, revealed a radiopaque foreign body (FB) in the right lower lobe. There was no history of aspiration. CT located the needle-shaped FB in the right posterobasal lower lobe segment bronchus. In bronchoscopy, the FB turned out to be a pin, of which the radiolucent plastic head was embedded in the peribronchial tissue. Extraction by flexible and rigid bronchoscopy failed; finally, thoracotomy and bronchotomy had to be performed to remove the pin. In delayed diagnosis of a tracheobronchial FB, CT scan is not only necessary to localise the FB but also to depict or rule out secondary pulmonary changes. Nevertheless, radiolucent components of a metallic FB might be invisible even in CT, leading to underestimation of its size and extension. Late diagnosis complicates removal of tracheobronchial foreign bodies and may even necessitate open surgery, including pulmonary resections.

    A 2-year-old, spayed female, mixed-breed dog was presented for evaluation of a progressive asymmetric tetraparesis and cranial nerve deficits with a 3-week duration. Computed tomography showed a contrast-enhancing lesion along the left side of the junction of the medulla and the cervical spinal cord. An exploratory surgery determined the presence of an intramedullary lesion of the first cervical spinal cord segment. The mass was removed through a dorsal midline myelotomy. Microscopic examination identified a foreign body granuloma that contained a dense, anisotropic outer wall, supporting the conclusion that the foreign body was of plant origin. The dog recovered to a more improved ambulatory status than prior to surgery.

    A three-year-old, 30-kg, spayed female German wirehaired pointer was presented for coughing, pyrexia and lethargy. Thoracic radiographs showed mild right-sided pleural effusion, moderate pneumothorax and a pulmonary lesion in the right middle or caudal lung lobe. A diagnosis of pyothorax was established by fine needle aspiration of the pleural effusion. Thoracoscopic exploration was performed using one-lung ventilation. A vegetal foreign body (grass awn) and an abscess were observed in the distal part of the right middle lung lobe. The foreign body was removed and a right middle lung lobectomy was performed, both thoracoscopically. No complications were noted. The dog was discharged 48 hours after surgery, and no recurrence of the clinical signs was observed during the follow-up time period (three years and three months). Thoracoscopy is a minimally invasive alternative to thoracotomy to explore and successfully treat some non-chronic pyothoraces in dogs, including lesions affecting the right middle lung lobe.

    Damselfish Chromis notata is a small fish less than 15 cm long and it is widespread in the Indo-Pacific Ocean. Of all the cases of fish bone foreign body (FBFB) disease at our hospital, a damselfish FBFB was very common, and a specific part of the bone complex was involved in the majority of cases. This study was performed to evaluate the clinical characteristics of damselfish FBFB in Jeju Island. We retrospectively reviewed the medical records from March 2004 to March 2011 for foreign body diseases. Among 126 cases of foreign body diseases, there were 77 (61.1%) cases of FBFB. The mean age ± standard deviation was 57.8 ± 12.7 yr, and this was higher in females 60.9 ± 14.6 yr vs 54.1 ± 8.7 yr. Damselfish was the most common origin of a FBFB 36 out of total 77 cases. The anal fin spine-pterygiophore complex of damselfish was most commonly involved and cause more severe clinical features than other fish bone foreign bodies; deep 2.7 ± 0.8 cm vs 2.3 ± 0.8 cm; P < 0.01, more common mural penetration 23/36 vs 10/41; P < 0.01, and longer hospital stay 12.6 ± 20.0 days 4.7 ± 4.8 days; P = 0.02. We recommend removing the anal fin spine-pterygiophore complex during cleaning the damselfish before cooking. PMID:23091319

    2014-01-01

    Summary Muslin-induced foreign body granulomas are rare delayed complications after wrapping of intracranial aneurysms. Few small case series have been reported, with a paucity of documented MRI findings. In addition, there are no reports on long-term radiological appearances or temporal evolution of conservatively managed patients. We thus report on the long-term radiological and clinical follow-up of two patients with asymptomatic muslin-induced foreign body granulomas after wrapping of recurrent middle cerebral arterial aneurysms. Both patients were successfully managed conservatively and remain asymptomatic three and six years after diagnosis of their granulomas. A literature review confirms that MRI features of muslin-induced foreign body granuloma are typical. Features include focal areas of elevated T2 signal with increased diffusion-weighted signal and thin rim enhancement. To the best of our knowledge, this is the first report to confirm that there is a corresponding reduction in apparent diffusion coefficient, as typical in an intracranial abscess. Thus a history of aneurysm wrapping is critical for diagnosis. Accurate clinical recognition of this exuberant inflammatory response will avoid misdiagnosis as pyogenic abscess or tumor and prevent unnecessary or invasive treatment. PMID:24556302

    Objective: A foreign body aspiration in the tracheobronchial tree is a dangerous medical condition in the childhood period. Although rigid bronchoscopy is a safe procedure, it may cause complications. The aim of this study was to present our bronchoscopy experience and to evaluate the efficacy of pre-operative administration of nebulized albuterol and budesonide combination for reducing intra-operative complications in foreign body aspirated cases. Methods: In this retrospective study our pediatric cases in which a foreign body was removed from tracheobronchial tree in last 8 years were analyzed. After excluding the patients who needed emergent and negative bronchoscopies, the remaining clinically stable 84 patients were compared for the effects of preoperative administration of nebulized albuterol and budesonide combination on bronchoscopy complications. Results: There were 51 boys (60.3%) and 33 girls (39.7%). There were 38 children in the non-nebulized group and 46 children in the nebulized group. We found that the combined albuterol and budesonide nebulization decrease complications such as arterial oxygen desaturation (p<0.05), and bronchospasm (p<0.05) during the bronchoscopic intervention. Conclusion: Preoperative nebulization of albuterol and budesonide combination may decrease perioperative complications of bronchoscopy. PMID:28367177

    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.

    2016-01-01

    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

    2009-09-01

    Periprosthetic infection is a foreign-body-associated infection that is characterised by delayed osteomyelitis of bone tissue surrounding artificial joint replacement. Most of these infections result from intraoperative bacterial contamination of the prosthetic device implanted. The period from contamination to clinically apparent infection can last months or even years. In these cases, the initial surgical procedure is often not blamed for the actual infection. Moreover, these infections often produce minimal symptoms that can be mistaken for aseptic loosening of the artificial joint replacement. The bacterial burden of the causative pathogen is low in these cases, a fact that need to be considered in the diagnostic procedures.Knowledge of the pathogenesis allows the orthopaedic surgeon to plan the diagnostic procedures and therapy as well. In this context, the pathogen's ability to form biofilm is of crucial significance and explains why it is necessary to remove the foreign body (prosthesis or other artificial devices, such as material used for osteosynthesis or spinal stabilisation) to control this type of infection. This article gives some basic information for better understanding of foreign-body-associated infection in order to improve diagnostics and therapy in the clinical routine.

    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.

    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.

    To be on the alert on infants with esophageal foreign body, and to pay more attention to the button battery esophageal foreign body, the clinical data of a 12-month-old infant with button battery esophageal foreign body, which was missed diagnosis for up to 4 months, is analyzed. And the related literature is reviewed. An esophagoscopy was carried out to remove the foreign body. A favorable outcome was achieved. When the infants have unexplained gastrointestinal symptoms, we should consider the possibility of an esophageal foreign body. We should pay attention to the button battery due to its highly corrosive to the esophagus. Timely diagnosis, reasonable operation are the keys to cure.

    Ocular trauma is the leading cause of visual loss in young adults. Open globe injuries with intraocular foreign bodies are an important part of this group, and in general an early surgery is required, in order to preserve the visual acuity and the eye globe. Primary surgical repair and foreign body removal may be performed using external magnet or vitrectomy. Based on published reports and our clinical experience we think that vitrectomy is safer procedure, giving better chance for good postoperative visual outcome.

    Regional suppurative meningoencephalitis and ventriculitis of variable chronicity was diagnosed in three young dogs residing in Colorado. Grass awns were grossly identified in the right occipital cortex of one dog and in the right lateral ventricle of another. Intralesional plant material was microscopically evident in the dura mater overlying the right occipital cortex of the third dog. One grass awn was identified as a floret of Hordeum jabatum. In each case, aerobic culture of brain tissue identified multiple isolates of bacteria. The dogs presented with clinically variable, rapidly progressive neurologic dysfunction, including tetraplegia, depressed mentation, and episodic extensor rigidity, ataxia, circling, stupor, vocalization, and head-pressing. Encephalitis due to bacteria introduced from migrating plant foreign material is a potential sequela of intranasal, periocular, or pharyngeal foreign bodies.

    Retained foreign bodies (RFBs) are a surgical complication resulting from foreign materials accidently left in a patient's body. This review attempts to give an overview of different types of RFBs, problems related to them and their management after the surgical operation. The internet was searched using the Google and Google scholar. In addition, relevant electronic journals from the University's library such as Entrez (including PubMed and PubMed central), Since Direct, Scirus, NIH.gov, Medknow.com, Medscape.com, Scopus, MedHelp.org, Cochrane library, WebMD.com, and World Health Organization Hinari. It shows that the major reasons of RFBs are emergency surgical operation with unplanned changes, patient high body mass index, and poor communication. To prevent this textile material should be radiopaque marked and must be counted once at the start and twice at the conclusion of all surgical procedures. If the count is incorrect, then radiography or manually re-exploration should be performed. Ultrasonography, computerized tomography, magnetic resonance imaging and radio frequency identification are also used in the proper identification of RFBs. Safety practice should be robust and simple enough to protect patient under the most chaotic of circumstances. Proper communication among the personnel participating in surgery aimed at preventing this medical negligence would help in mitigating such errors. Finally, the surgeon should not only follow the standard recommended procedure, but also report cases of RFBs. PMID:24669327

    Objective: Foreign bodies in the ear are mainly encountered in children. This can often pose a problem especially in an accident and emergency department where a microscope or expert help is not routinely available. This paper presents a simple, safe, and effective way of ear syringing. The ease and simplicity of the procedure along with the equipment are described. Method and result: The equipment consists of a "disposable" sterile kit, consisting of a 20 ml syringe, saline at body temperature and 14 or 16 gauge cannula (without the needle). An in vitro experiment was conducted to calculate the pressure generated by the water jet on the eardrum. The pressure was well below the pressure required to burst a tympanic membrane, and hence this technique is safe to use. Conclusions: Ear syringing is an effective and easy way of removing most foreign bodies. A detailed history and an otoscopic examination must precede the procedure. The novel method of syringing described in this paper with the usual safeguards could be a useful adjunct in the management of this common condition. PMID:15788826

    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

    Lung tumors are extremely rare in the pediatric population, comprising only 0.2% of all malignancies in children. Among them, mucoepidermoid carcinoma (MEC) is even rarer with a reported frequency of 0.1% to 0.2%. MEC is defined by the World Health Organization as a tumor characterized by a combination of mucus-secreting, squamous, and intermediate cell types. We describe the case of a 4-year-old girl who presented with a history of intermittent fever and nonproductive cough of 1-month duration after foreign body aspiration. The chest X-ray showed complete collapse of the left lung. After removal of the foreign body, the lung expanded well after. However, the control chest X-ray done after 5 days showed again complete collapse of the left lung. The biopsy specimen taken during bronchoscopy confirmed the diagnosis of low-grade MEC. Fluorescence in situ hybridization (FISH) confirmed the presence of MAML2 rearrangement. Complete surgical resection with preservation of lung parenchyma was performed. No adjuvant therapy was needed. Repeat bronchoscopy was performed 2 months after surgery and showed no recurrence of the tumor. In conclusion, a remote chest X-ray after removal of a foreign body is necessary to avoid missing a rare serious underlying disease such as MEC. According to the size and the location of the tumor, complete surgical removal is sufficient without additional treatment in case of low-grade tumor. The presence of MAML2 rearrangement confers a favorable outcome and may have long-term implications for the clinical management. PMID:27994904

    A 51-year-old woman with a history of a left orbital floor fracture repaired with stainless steel mesh in 1973 presented for evaluation of chronic head tilt and strabismus. Ocular motility examination revealed severely restricted eye movements with a large-angle esotropia and left hypotropia, and positive forced ductions. Dilated fundoscopic examination was notable for a small metal wire surrounded by hyperpigmentation in the inferonasal quadrant. CT confirmed globe penetration by the mesh floor implant. Although treatment options were contemplated, after further review, observation was chosen. This is a rare case of wire mesh causing a well-tolerated metallic intraocular foreign body and strabismus.

    A Sputnik lens implant removed after five years because of bullous keratopathy exhibits a dense covering of its Supramid anterior staves with large foreign body giant cells, while its Prolene loops and Polymethylmethacrylate optics have attracted only few of these cell units. The glass-membrane-like component of the reactive membrane also shows significant differences on the different parts of this implant. The use of observation of the components of reactive membranes on lens implants as indicators of toleration in the eye is suggested.

    Background. Reports of retained colorectal foreign bodies (CFBs) are no longer considered uncommon. We present a case where a retained CFB was retrieved using a modified TAMIS technique using standard instruments and trocars. Case Report. A 52-year-old man presented with a CFB. We report our technique of extraction with standard laparoscopic instruments without specialized access platforms. Conclusions. This modified TAMIS technique is well suited for resource poor environments because it requires no specialized equipment, platforms, or additional skill sets compared to conventional laparoscopy.

    Most patients with voluntary anal insertion of a foreign body (IFB) present to the emergency department and are then managed by the surgical team. This report reviews the medical literature on IFB and includes results of a chart review of operative logged interventions and clinically coded procedures for anal IFBs at a single acute hospital in the United Kingdom between May 2009 and September 2013. The objective was to establish the current practice in the management of anal IFB and update a framework for the initial workup, surgical procedure, and appropriate mental health intervention.

    It is known [1 3] that in order to provide heat shield or to improve the aerodynamics of the body strong injection of cooling gas into the supersonic stream is utilized. Analysis of flow characteristics in the neighborhood of the solid body in the presence of strong single-phase injection and the effect of injection on the aerodynamic characteristics of some axisymmetric bodies are given, e.g., in [2 4]. Supersonic flow past a blunt-nosed axisymmetric body with blowing of a mixture of gas and solid particles through a porous segment in the leading edge region is considered in the present paper. Such a situation could occur in modeling the breakdown of the heat shield of a flight vehicle during its reentry into the thick layers of atmosphere and also in the case of forced introduction of particles in the flow of the injected gas in order to break up the leading edge shock and accordingly the variation in the drag of the body [5]. A description of the trajectory of the particles has been obtained as a result of numerical and analytical solution of the problem and their analysis is used to arrive at conclusions on their intersection and, consequently, also on the multiple-valued nature of the flow parameters in the neighborhood of the line dividing the external flow and the injected two-phase mixture. Sufficient conditions for multiple-valuedness have been analytically found which agree with numerical results. It has been established that with a change in composition of sufficiently small particles within the limits 0.1 to 0.6 by weight of the injected mixture the drag coefficient of the body does not change by more than 10%.

    2016-01-01

    Purpose This study was performed to characterise the nature, clinical presentation, mode of insertion, and management of intravesical foreign bodies in patients treated at our hospital. Methods Between January 2008 and December 2014, 49 patients were treated for intravesical foreign bodies at King George Medical University, Lucknow. All records of these patients were retrospectively analysed to characterise the nature of the foreign body, each patient’s clinical presentation, the mode of insertion, and how the case was managed. Results A total of 49 foreign bodies were retrieved from patients’ urinary bladders during the study period. The patients ranged in age from 11 to 68 years. Thirty-three patients presented with complaints of haematuria (67.3%), 29 complained of frequency of urination and dysuria (59.1%), and 5 patients reported pelvic pain (10.2%). The circumstances of insertion were iatrogenic in 20 cases (40.8%), self-insertion in 17 cases (34.6%), sexual abuse in 4 cases (8.1%), migration from another organ in 4 cases (8.1%), and assault in 4 cases (8.1%). Of the foreign bodies, 33 (67.3%) were retrieved by cystoscopy, while transurethral cystolitholapaxy was required in 10 patients (20.4%), percutaneous suprapubic cystolitholapaxy was performed in 4 patients (8.1%), and holmium laser lithotripsy was performed in 2 patients (4.08%). Conclusions Foreign bodies should always be included in the differential diagnosis when evaluating a patient who presents with chronic lower urinary tract symptoms. A large percentage of foreign bodies can be retrieved using endoscopic techniques. Open surgical removal may be performed in cases where endoscopic techniques are unsuitable or have failed.

    Despite advances in imaging techniques, the detection of vegetative foreign bodies in soft tissues remains a difficult and sometimes even a challenging task. Clinical evaluation of such patient may present several months or even years after the initial injury and clinician may fail to elicit an antecedent skin puncture. X-ray examination will miss radiolucent foreign bodies. A 15-year-old boy presented with a draining non-healing sinus at the lateral aspect of his right thigh for 9 months. Musculoskeletal ultrasonography was ordered after ruling out chronic osteomyelitis to detect possible lesions around the thigh. High-frequency linear ultrasonic probe readily detected an elongated foreign body within the vastus lateralis muscle. A long piece of wood was confirmed at surgery. Non-healing sinus with normal finding in radiograph following old trauma should raise the suspicion of implanted radiolucent foreign body/bodies. The role of diagnostic ultrasound as a valuable screening tool for the detection of foreign body is briefly reviewed. PMID:22871025

    Summary Background Fractures of mid-face were first described by Le Fort and are classified into three categories – Le Fort I, Le Fort II and Le Fort III. The pterygoid processes of the sphenoid bone are fractured in all the three categories of Le Fort fractures as the sphenoid bone connects the cranium vault to the facial bones. Fractures of the pterygoid processes without associated Le Fort fractures are rare and are usually associated with fractures of the mandible, temporal bone or other facial bones. An isolated fracture of pterygoid plates without associated Le Fort fractures or fractures of other mid-face bones are exceedingly rare. Case Report We present a case of an isolated fracture of the right lateral pterygoid plate by a penetrating foreign body (wooden twig) in an adult male who presented with discharging sinus in the oropharynx. The presence of the foreign body was confirmed on computed tomography and was removed under general anesthesia via submandibular incision. The patient had an uneventful postoperative hospital stay and was asymptomatic on a follow-up five months later. Conclusions This article emphasizes the fact that pterygoid plates may be fractured without an associated Le Fort fracture or a fracture of the mandible. This is the first case of an isolated pterygoid plate fracture in the literature. PMID:28382185

    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.

    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.

    A metal detector reveals the presence of metallic objects by measuring the change in the inductance of a coil placed near a metallic mass. The device used in this study is similar in principle to those used for passenger surveillance in airports except for its smaller size and simpler design. In this study, we compared the accuracy of a metal detector with that of plain radiographs for the localization of ingested metallic objects. Twenty-eight consecutive patients with the presumptive diagnosis of metallic foreign-body ingestion were examined with a metal detector. The results were compared with those of plain radiographs which were considered the gold standard. Fifteen positive cases and 13 negative cases were correctly diagnosed by metal detector examination. No false-positive or false-negative results occurred. Our experience suggests that metal detection is a simple and accurate technique for the localization of ingested metallic objects and provides information equivalent to that from plain radiographs for the treatment of patients with suspected foreign-body ingestion.

    A 2-year-old male castrated Springer Spaniel with a 3-week history of waxing and waning right sided exophthalmos, periorbital swelling, chemosis, and fundic changes was examined. Ophthalmic examination of the right eye revealed slight chemosis and nictitating membrane protrusion. Indirect ophthalmoscopy showed an approximately 8 mm peripapillary hyporeflective tapetal lesion with subretinal edema consistent with a bulbar/retrobulbar disease process. Inflammatory or neoplastic diseases were the main differential diagnoses. Ancillary diagnostics (ocular ultrasound and computed tomography) showed a focal, poorly defined dense tissue involving the caudomedial aspect of the right globe, adjacent to the optic nerve head without apparent orbital involvement. Considering the duration, location, and severity of the clinical findings, enucleation of the right globe was performed. Histopathology revealed focal thickening of the posterior wall with severe pyogranulomatous inflammation, surrounding a foreign body most consistent with plant material embedded between the sclera and the choroid (suprachoroidal). This report describes a rare case of a scleral/suprachoroidal foreign body (plant material), and outlines the difficulty of establishing an etiological diagnosis using standard ocular imaging.

  14. Lack of Platelet Endothelial Cell Adhesion Molecule-1 Attenuates Foreign Body Inflammation because of Decreased Angiogenesis

    Platelet endothelial cell adhesion molecule-1 (PECAM-1, CD31) is a 130-kd member of the immunoglobulin superfamily of proteins, expressed on endothelial cells, leukocytes, and platelets. Antibody-blocking studies have implicated it in modulating leukocyte transmigration and angiogenesis. However, the generation of the PECAM-1 knockout mouse has shown that its function can be compensated for by similarly acting proteins because most acute inflammatory models proceed in a comparable manner in wild-type and knockout animals. We decided to examine the function of PECAM-1 in the chronic process of foreign body inflammation. We show that PECAM-1-deficient mice exhibit attenuated neutrophil infiltration in and around a subcutaneous polyvinyl acetyl implant. Bone marrow engraftment studies indicate that the lack of CD31 expression on the endothelium determines the diminished leukocyte accumulation in the knockout implants. Specifically, we find that decreased angiogenesis (as manifested by lower vessel density, decreased hemoglobin content, and less laminin deposition) correlates with lower neutrophil accumulation in the knockout animals. This study indicates that the absence of endothelial PECAM-1 results in decreased angiogenesis and therefore in diminished delivery of leukocytes to the foreign body implants. PMID:12598328

    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.

    2015-06-01

    Pulmonary foreign-body granulomatous embolization has been described secondary to crystal precipitation in total parenteral nutrition (TPN) as well as when pharmaceutical tablets are crushed and injected intravenously. Extensive granulomatous embolization may cause pulmonary hypertension and death due to acute cor pulmonale. We report the case of a 34-year old woman who had been receiving TPN post-operatively secondary to complications of a paraesophageal hernia repair. During and following receiving TPN, she experienced episodes of hypoxia, tachycardia, fever, and hypotension. Computed tomography scans of the thorax showed centrilobular nodules, tree-in-bud and ground-glass opacities, as well as findings of pulmonary hypertension. Following an episode of hypoxia she was found unresponsive and died despite resuscitative efforts. Microscopic examination of the lungs following post-mortem examination revealed occlusive granulomatous inflammation of the pulmonary arterial vasculature by crystalline material. The morphologic and histochemical patterns of the crystals were suggestive of microcrystalline cellulose, a finding that was confirmed by energy dispersive X-spectroscopy and infrared spectroscopy. Ancillary tests did not support that the crystalline material was the result of TPN precipitation. Foreign-body granulomatous embolization leading to acute core pulmonale may occur as a complication of both intravenous injection of oral medications as well as of TPN crystallization. The source of crystalline material may be difficult to discern based solely on morphological assessment or by histochemical staining. Ancillary studies such as energy dispersive X-spectroscopy or infrared spectroscopy should be performed to definitively discern the two entities.

  17. Hypercalcemia in a male-to-female transgender patient after body contouring injections: a case report

    PubMed Central

    2014-01-01

    Introduction Body contouring injections by non-licensed providers are frequently sought out by a subset of the male-to-female transgender community. Although short-term side effects such as pulmonary embolism and injection site infection are well known, long-term consequences of such practices are less well studied. Case presentation Here we describe the case of a 40-year-old African American male-to-female transgender patient who presented to our institution with hypercalcemia and acute renal failure secondary to body contouring injections with industrial strength silicone by non-licensed providers, a decade prior to her visit. Work-up revealed an extensive granulomatous inflammatory process in the injection area resulting in electrolyte abnormalities and kidney injury. The patient’s lab results and symptoms responded well to long-term corticosteroid treatment and correlated with treatment adherence. Conclusion Affected patients can sometimes present with unusual clinical symptoms many years after silicone injections. In a constantly growing transgender community that often utilizes non-licensed providers for silicone injections, the medical community will likely face an increasing number of patients with long-term side effects of such practices. Therefore, it is imperative for physicians to recognize such cases promptly and initiate potentially life-saving treatment. PMID:24572248

    The removal of embedded blast-generated fragments from soft tissue is very difficult, especially in the head and neck regions. First, because many retained foreign materials are non-metallic and can, therefore, not be detected by fluoroscopy, and second, because a broad exploration of the soft tissue is not possible in the facial area for functional and cosmetic reasons. Intraoperative navigation computer-assisted surgery (CAS) may facilitate the retrieval of foreign bodies and reduce exploration trauma. In a blind trial, five test specimens of different materials (glass, metal, wood, plastic, and stone) were inserted on the left and right sides of the head and neck of ten body donors through an intraoral incision. A second physician then detected and removed the foreign bodies from one side of the body without and from the other side of the body with navigation. We measured the duration of surgery, the extent of tissue trauma caused during surgery, the time it took to remove the foreign bodies, and the subjective evaluation of the usefulness of navigation. With the aid of the navigation system, the various foreign bodies were detected after an average of 26.7 (±35.1) s (p < 0.0001) and removed after an average of 79.1 (±66.2) s (p = 0.0239), with an average incision length of 10.0 (±3.5) mm. Without the navigation system, the foreign bodies were located after an average of 86.5 (±77.7) s and removed after an average of 74.1 (±45.9) s, with an average incision length of 13.0 mm (±3.6) mm (=0.0007). Intraoperative navigation systems are a valuable tool for removing foreign bodies from the soft tissue of the face and neck. Both the duration of surgery and the incision length can be reduced using navigation systems. Depending on the material of the foreign bodies and the signal intensity in the CT/MRI scanner, however, the detection reliability varies. All in all, navigation is considered to be a useful tool.

    2002-01-01

    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.

    Radiography or computed tomography is the most widely available imaging tool for foreign body detection. However, the detectability of low-density substances by x ray is very poor when located in soft tissues. Various dielectric loss factors of foreign bodies contribute great microwave absorption heterogeneity compared with the surrounding tissue. A fast thermoacoustic tomography system at 1.2 and 6 GHz was developed to detect foreign targets in small animals. The 6 GHz system had a much higher signal-to-noise ratio in near-surface imaging but smaller imaging depth than the 1.2 GHz system. The effects of microwave distribution inhomogeneity on nonuniform excitation of acoustic pressure were studied and a corresponding calibration algorithm for image distortion was provided and experimentally examined. Thermoacoustic images of radiolucent objects including glass fiber, wood, and bamboo hidden in phantom and residual in living mice were compared with radiography and ultrasonography. Good contrast was obtained between the foreign bodies and the tissue surrounding it, and the location and size of the lesion targets in thermoacoustic images were in good agreement with the actual sample. The experimental results demonstrate that thermoacoustic tomography may become the ideal modality for radiolucent foreign body detection and imaging in animals and human.

    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

    Intratracheobronchial foreign bodies are common accidents in children. In developed countries, the removal of these intratracheobronchial foreign bodies is performed with flexible or rigid fiberoptic bronchoscopy. Resorting to surgery is rare. In the inadequate medical context described, suitable medical technical equipment doesn't exist. Removal alternatives are necessary in order to avoid sanitary evacuation which is not always within patients' means. In this study, the authors describe the removal of an intratracheobronchial foreign body opaque to X-rays with foreign body forceps. The forceps, passed through the orotracheal intubation probe, were guided by an image intensification system in a traumatology operating theatre.

    Oesophageal foreign bodies (FBs) are commonly encountered in an otolaryngology setting. The majority of such cases remain in the paediatric population, where obtaining an accurate history of events is challenging. Oesophageal FBs present in a variety of ways other than dysphagia, which may result in delayed presentation, diagnosis and subsequent treatment. Where an ingested FB is a battery, early removal is advocated owing to the potential for significant complications, a problem highlighted by a patient safety alert issued by NHS England. A common paediatric presentation, torticollis has a multitude of potential underlying causes. We present an unusual case of torticollis in a two-year old girl, subsequently revealed to be caused by an ingested button battery. PMID:26890847

    We report a case of cervical abscess after the ingestion of foreign body (chicken bone) secondary to probable esophageal perforation that it was sent to us with suspicion of mediastinal complication. The girl, 17 years-old, nothing else to arrive our hospitalary center required entrance in ICU due to her severe clinical process: High fever, intense neck-thoracic pain, laterocervical diffuse and progressive left inflammation and bad general state. The CT showed the presence of a well defined abscess and abundant aerial component that dissected the cervical muscles that made necessary to perform drainage verifying intraoperatively no mediastinal involvement. The culture of the purulent collection revealed Streptococcus anginosus/milleri resistant to clindamicine but sensible to penicilina and derivatives. We exposed a serie of considerations at respect of such microorganism and its clinical signification.

    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.

    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.

    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

    Introduction Ingestion of foreign bodies has been previously reported in some patients with schizophrenia. This behavior may be a manifestation of delusional beliefs or a response to command hallucinations and can lead to severe complications. Case Presentation This paper reports a patient with schizophrenia who, as a manifestation of his illness, ingested a metallic skewer to kill ademon inside his abdomen that he believed was controlling him. As a result, he developed an acute intestinal perforation and underwent surgery. Conclusions It is of a great importance to closely monitor the therapy compliance of patients suffering from mental illnesses. This will benefit them by preventing some of the serious complications of their disease, which may include life-threatening conditions such as intestinal perforation that needs surgical intervention.

    Extra peritoneal bladder injuries are very difficult to diagnose on clinical examination alone. CT-scan with cystogram (Contrast: Ultavista300) is a reliable diagnostic tool to evaluate such injuries at an early stage. For accurate diagnosis of bladder injury, enhancement of bladder contents is necessary otherwise extravasated urine can be mistaken for haematoma or ascites. Retrograde filling of bladder with minimum 250 -300 ml of contrast material is necessary before performing abdominopelvic CT to rule out any form of bladder injury. Therefore in case of suspected bladder injury CT cystogram should be performed at the time of initial CT examination in the emergency room. We report a case of extraperitoneal bladder injury and foreign body in urinary bladder after a firework injury.

    The study objectives were to determine the impact of a nationwide educational campaign on the incidence of foreign body aspiration (FBA) in Israeli children. Impressed by the alarming number of FBAs, we conducted an educational campaign through the media during 1982-1983. The campaign included television and radio broadcasts, newspaper articles and interviews, and medical educational programmes in community paediatric care centres. Questionnaires were sent to all Departments of Paediatrics in Israel. Results showed a reduction in the incidence of FBA by 35% in 1983 as compared to 1981. Re-evaluation studies conducted in 1992 showed no further reduction of FBA. CONCLUSION. Continuous and extensive educational programmes should be undertaken by the health authorities if FBA is to be prevented. Furthermore, it is important to legislate mandatory labelling of seed and nut containers with the warning that the intake of seeds is dangerous to children under 5 years of age.

    A 66-year-old woman underwent right lower lobectomy and partial resection of the middle lobe for Stage I A double lung cancer. Five years after the operation, a routine computed tomography (CT) scan showed a mass on the staple line at the middle lobe. The mass was enlarged on CT scan after 6 months. A definitive diagnosis could not be made by bronchoscopic examination and fluoro-2-deoxy-glucose(FDG)/positron emission tomography( PET)-CT showed FDG uptake in the mass( early phase:SUVmax=3.24, late phase:SUVmax=4.31). Local recurrence of lung cancer was not completely denied, and right middle lobectomy was performed. Histopathologically, the resected specimen revealed granuloma with foreign body reaction. We should keep in mind the possibility of granuloma as differential diagnosis of lung cancer when using stapler.

    The inhalation of a foreign body (FB) is rare in the adult although more common in the child. The type of FB varies greatly according to the dietary and educational habits of the populations studied. In Morocco, metal FB are common, especially the pins used to attach scarves. These pins migrate easily and wedge at a distance making them difficult to extract by endoscopy, thereby resulting in thoracotomy. The authors present two cases of the inhalation of a pin held in the mouth during a sudden emotion. Since the clinical symptomatology is inconspicuous, thoracic imaging is used to locate the FB. After a failure to extract it by rigid bronchoscopy combined with flexible bronchoscopy, the two patients underwent surgery. The sequellae were simple. Prevention in both the child and in the adult are the best way to avoid this incident that may have dramatic results.

    Civil processes and criminal procedures against physicians and/or medical assistants due to retained foreign bodies following surgery are not uncommon within the framework of the booming liability disputes in hospitals. As the protection and safety of the patient is the highest priority, the physician must take all feasible and reasonable precautions against such a possibility during both in- and outpatient operations.These include clear, written instructions for the assisting medical personnel in relation to count control, its documentation, final revision and specification in the surgical report. The delegation of swab and instrument counts to reliable OP nurses and other personnel is juristically possible and leads to their own responsibility, based on principle of basic trust, i.e. the physician can rely on the correct count of abdominal sponges, swabs etc. If an error does occur, the organizational liability does not fall on those responsible for the operation.

    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.

    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.

    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

    Background: Pneumomediastinum (PM) secondary to foreign body aspiration (FBA) is rare in children. Although it is mainly benign, some cases may be fatal. Due to the rare nature of this clinical entity, proper assessment and management have been poorly studied so far. Here, we characterized the presentation and management of this clinical entity and provided an evaluation system for the management. Methods: We retrospectively reviewed children with PM secondary to FBA, who were treated in Beijing Children's Hospital from January 2010 to December 2015. All patients were stratified according to the degree of dyspnea on admission, and interventions were given accordingly. Bronchoscopic removals of airway foreign bodies (FBs) were performed on all patients. For patients in acute respiratory distress, emergent air evacuation and/or resuscitations were performed first. Admission data, interventions, and clinical outcomes were recorded. Results: A total of 39 patients were included in this study. The clinical severity was divided into three grades (Grades I, II, and III) according to the degree of dyspnea. Thirty-one patients were in Grade I dyspnea, and they simply underwent bronchoscopic FBs removals. PM resolved spontaneously and all patients recovered uneventfully. Six patients were in Grade II dyspnea, and emergent drainage preceded rigid bronchoscopy. They all recovered uneventfully under close observation. Two exhausted patients were in Grade III dyspnea. They died from large PM and bilateral pneumothorax, respectively, despite of aggressive interventions in our hospital. Conclusions: PM secondary to FBA could be life-threatening in some patients. The degree of dyspnea should be evaluated immediately, and patients in different dyspnea should be treated accordingly. For patients in Grade I dyspnea, simple bronchoscopic FBs removals could promise a good outcome. For patients in Grade II dyspnea, emergent air evacuation and/or resuscitation should precede a

    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

    Esophageal foreign body impaction (EFBI) often requires urgent evaluation and treatment, but characteristics of emergency department (ED) care such as timing of presentation and therapeutic procedures and costs of care are unknown. We aimed to study health-care utilization for patients with EFBI presenting to the ED. Cases of EFBI from 2002 to 2009 were identified by querying three different databases from the University of North Carolina Hospitals for all records with ICD-9 CM code 935.1: 'foreign body in the esophagus.' Charts were reviewed to confirm EFBI and extract pertinent data related to the ED visit, including time of presentation, length of ED stay, medications administered, type of procedure performed, characteristics of procedures, and time to therapeutic procedure. Hospital charges for EFBI encounters and consult fees were determined from the Physicians' Fee Reference 2010, and were compiled to estimate costs. Of the 548 cases of EFBI identified, 351 subjects (64%) presented to the ED. A total of 118 (34%) patients received a medication to treat EFBI, which was only effective in 8% of those patients. Two hundred ninety (83%) subjects underwent a procedure including esophagogastroduodenoscopy (EGD) (n=206) or ear, nose, and throat surgery (ENT)-performed laryngoscopy/esophagoscopy (n=138). Admission to the hospital occurred in 162 (46%) of cases. There was no relationship between ED arrival time and time-to-procedure or total time in ED. There was also no significant relationship between delivery of ED medications and likelihood of undergoing a procedure, or between ED arrival time and delivery of medications. The charges associated with a typical EFBI episode ranged from $2284-$6218. In conclusion, the majority of patients with EFBI at our institution presented to the ED. Medical management was largely ineffective. A therapeutic procedure was required to clear the EFBI in most patients. Time of ED arrival made no difference in time

    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

    1. Intracerebroventricular administration of histamine to cats caused hypothermia followed by a rise in body temperature. 2-Methylhistamine caused a similar biphasic response, while 3-methylhistamine had no effect on body temperature and 4-methylhistamine produced a delayed hyperthermia. Some tolerance to the hypothermic activity developed when a series of closely spaced injections of histamine was given. 2. Doses of histamine and 2-methylhistamine which altered body temperature when given centrally were ineffective when infused or injected I.V. 3. Pyrilamine, an H1-receptor antagonist, prevented the hypothermic response to histamine. 4. Hypothermic responses to histamine at an environmental temperature of 22 degrees C were comparable to responses in a cold room at 4 degrees C in both resting animals and animals acting to depress a lever to escape an external heat load. A change in error signal from the thermostat could account for these results. However, lesser degrees of hypothermia developed when histamine was given to animals in a hot environment. In some, but not all animals, this smaller response could be attributed to inadequate heat loss in spite of maximal activation of heat-loss mechanisms. 5. The hyperthermic response to histamine was antagonized by central, but not peripheral, injection of metiamide, an H2-receptor antagonist. 6. The results indicate that histamine and related agents can act centrally to cause both hypothermia, mediated by H1-receptors, and hyperthermia, mediated by H2-receptors.

    To study pharmacokinetics of injection of iodine-131 labelling MEI-TUO-XI monoclonal antibody (hepatoma monoclonal antibody HAb18 F(ab')2) in vivo. 24 cases of primary hepatocelluar carcinoma (PHC) were equally divided into the low dose group, middle dose group and high dose group. After the relevant injection was administrated into the hepatic artery of each case, intravenous blood and urine samples were separately collected at different time for determination of the radioactive count ratio (min(-1)). The proportion of 131I-HAb18 F(ab')2 in serum of each blood sample was determined, and the radioactive count ratio (min(-1)) of druggery for each blood sample was revised according to the proportion. The pharmacokinetic parameters were calculated using DAS ver 1.0 (Drug And Statistics for Windows) program. The component of urine radiomaterial was determined and the percentages of urine radioactivity in administration dosage were calculated. The catabolism of the injection with time accorded with dynamics two-compartment model. The catabolism product was mainly free-131I and was excreted via kidney; the urine radioactivity was 47.70%-51.16% of administration dosage during 120 h after administration of drug. Therefore, the pharmacokinetics of the injection can satisfy the clinical demands. The drug dose recommended for clinical use was 27.75 MBq of the injection for each kg of human body.

Confirmed by necropsy, a porcupine quill had migrated to the patient's left cerebral hemisphere, likely through the oval foramen. This case study demonstrates the efficacy of CT in visualizing a quill in the canine brain.

    Objectives: To compare the usefulness of four imaging modalities in visualizing various foreign bodies of different sizes. Methods: Foreign bodies of four sizes (0.5, 1, 2 and 3 mm) including metal, tooth, wood, plastic, stone, glass and graphite were embedded in six fresh sheep heads on bone surface between the corpus mandible and muscle, and inside the tongue muscle. A human dry skull served as an air-filled space. Plain radiography, CT, MRI and ultrasonography were used, and four skilled radiologists rated the findings individually. Results: All embedded foreign bodies except wood were best visualized using CT. Wood could only be detected using ultrasonography, and then only when fragments were >0.5 mm in size. Plain radiography and CT were almost equally accurate in visualizing metal and graphite. MRI was the least useful imaging technique. Conclusions: In cases with suspected foreign bodies in the maxillofacial region, CT seems to be the optimal initial imaging study. Wood, however, could only be detected using ultrasonography.

    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. PMID:27578936

    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

    A preliminary investigation has been performed to determine the influence of stagnation point water injection on the hypersonic aerodynamic forces and moments for two-dimensional blunt bodies. This investigation was performed in the Langley 20-Inch Mach 6 Air Tunnel, and represents the qualitative first phase of a study to examine the potential benefits of water injection to reduce aerodynamic drag and aero-heating. Tests with a 4-inch diameter hemisphere cylinder and a 4-inch diameter cylinder with a span 1.5 times the diameter were performed over a range of free-stream unit Reynolds number from two million to six million per ft and of angle of attack (-5 deg to 5 deg) with water and gaseous nitrogen injection at the geometric stagnation point. The momentum flux ratio, that is, the ratio of the momentum flux of the jet to that of the free-stream flow, was varied from the non-blowing value of zero up to 0.00031 by maintaining the jet momentum fixed and varying the free-stream momentum, hence Reynolds number. The effect of water injection on the aerodynamic drag coefficient for the hemisphere cylinder was observed to be negligible as the momentum flux ratio was increased to 0.00017, but decreased significantly as this ratio increased above 0.00017; a nearly 50 percent reduction in drag occurred for a factor of two increase in momentum flux ratio.

    We used for the first time a vascular casting material to take advantage of a simple tracing procedure and to isolate the peculiar features of acupuncture point injections. The polymer Mercox was injected into the skin of a dead mouse at acupuncture points along the bladder meridian lines. After a partial maceration of the whole body with a potassium-hydroperoxide solution, we anatomized it under a stereomicroscope to trace the injected Mercox. Many organs were checked to determine whether or not they contained some Mercox tracing. Connections between the injection sites along the acupuncture points were observed. Two to three layers of Mercox in a plate shape were found under the skin at the acupuncture points, and Mercox travelled throughout the adipose tissue, the fascia, and the parietal and visceral serous membranes inside the organ's parenchyma. The casting material Mercox used with a modified partial maceration procedure is a promising method for visualizing the routes of the meridian system and the primo vascular system. The routes for Mercox are different from those of the blood and lymphatic vessels.

    Foreign body (FB) ingestion is a common emergency as well as a major cause of accidental injury and represents a severe public health problem in childhood, especially in infants. Most cases of FB ingestion reported in children aged between 6 months and 3 years depend primarily on the fact that young children are more likely to explore objects using their mouth and are not able to distinguish edible objects from nonedible ones, their teeth are physiologically lacking, and they have poor swallowing coordination. Although, sometimes it can cause serious complications, FB ingestion generally has a low mortality rate. However, accidental ingestion of magnetic toys, as a rare kind of FB mostly encountered in children, has now become more common due to the increased availability of objects and toys with magnetic elements. The majority of magnetic FB traverse the gastrointestinal (GI) system spontaneously without complication, but in rare cases may cause severe damages to the GI tract due to its special pathogenesis [Kay and Wyllie: Curr Gastroenterol Rep 2005;7: 212-218]. Ingestion of multiple magnets may be related to increased morbidity resulting in a delay of recognition of FB injury that can lead to serious complications and require surgical resolution.

    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 paper describes 239 children with bronchopulmonary disease due to foreign body (f.b.) aspiration treated in our center during between 1980-1992. Twenty-eight percent of the cases had been referred to hospital without any suspicion of f.b. aspiration. Almost half of the children (49.7%) were below the age of 2 years. Boys were affected more often (61.5%) than girls. In 61.1% the cases the f.b. had been aspirated into the right bronchial tree. Pieces of nuts were the most common f.b. - 35.1%. The most common chest X-ray symptoms were disturbances of bronchial patency (74.1%). Non-metalic, but potential shadowing f.b. like bones and teeth gave the clear signs only in 17.6% of the cases. After f.b. aspiration chronic irreversible lesions such as bronchiectasis and lung fibrosis were observed in 18.8% of the children. The prevalence of bronchiectasis was proportional to the duration of deposition. If the f.b. had been removed within the first month after aspiration we observed no complications. After aspiration of ears of grain, bronchiectasis was present in 80% of cases. Aspiration of f.b. into the left bronchial tree very often caused ventilation disturbations. Such cases were diagnosed and treated earlier than cases of right side f.b. aspirations. As a consequence bronchiectasis in the left lung was observed 2.7 less frequently.

    Although nitric oxide (NO) is a well documented effector molecule in rodent macrophages, its significance in human mononuclear phagocytic cells has been controversial. The foreign body inflammatory reaction around loosened joint replacement implants leads to formation of an osteolytic granulomatous pseudo-synovial membrane rich in activated macrophages. We studied 13 specimens of interface membrane tissue collected from revision surgery of aseptically loosened hip and knee prostheses for the presence of inducible NO synthase (iNOS). The presence of iNOS was demonstrated immunohistochemically in 10 of these specimens. Within the tissue this enzyme was confined to macrophages and vascular endothelial cells. iNOS activity was demonstrated biochemically by measuring the calcium-independent generation of citrulline from L-arginine, and the presence of iNOS mRNA was demonstrated using reverse transcriptase polymerase chain reaction. NO synthesis in the interface tissue may be an important factor in the maintenance of the inflammatory and osteolytic processes. Images Figure 1 Figure 2 Figure 3 PMID:9060826

    The implantation of non-biological materials, including scaffolds for tissue engineering, ubiquitously leads to a foreign body response (FBR). We recently reported that this response negatively impacts fibroblasts encapsulated within a synthetic hydrogel and in turn leads to a more severe FBR, suggesting a cross-talk between encapsulated cells and inflammatory cells. Given the promise of mesenchymal stem cells (MSCs) in tissue engineering and recent evidence of their immunomodulatory properties, we hypothesized that MSCs encapsulated within poly(ethylene glycol) (PEG) hydrogels will attenuate the FBR. In vitro, murine MSCs encapsulated within PEG hydrogels attenuated classically activated primary murine macrophages by reducing gene expression and protein secretion of pro-inflammatory cytokines, most notably tumor necrosis factor-α. Using a COX2 inhibitor, prostaglandin E2 (PGE2) was identified as a mediator of MSC immunomodulation of macrophages. In vivo, hydrogels laden with MSCs, osteogenically differentiating MSCs, or no cells were implanted subcutaneously into C57BL/6 mice for 28 days to assess the impact of MSCs on the fibrotic response of the FBR. The presence of encapsulated MSCs reduced fibrous capsule thickness compared to acellular hydrogels, but this effect diminished with osteogenic differentiation. The use of MSCs prior to differentiation in tissue engineering may therefore serve as a dynamic approach, through continuous cross-talk between MSCs and the inflammatory cells, to modulate macrophage activation and attenuate the FBR to implanted synthetic scaffolds thus improving the long-term tissue engineering outcome.

    Children, and in particular young children under the age of three, are the most vulnerable for aspiration and ingestion of foreign bodies (FBs). The Red Cross War Memorial Children’s Hospital in Cape Town is the only children’s hospital in South Africa and is unique in having a dedicated trauma unit for children under the age of 13 as part of its institution. Core activities of Childsafe South Africa (CSA), located at the hospital, are data accumulation and interpretation, development of educational programmes, health inculcation and advising in legislation involving child health. To achieve this task, CSA works in close co-operation with government, industry, non-governmental and community predicated organisations, community groups and individuals. A database of all children treated for trauma at CSA has been maintained since 1991; it currently contains detailed information of over 170,000 injuries in children under the age of 13. This review consists of a literature review combined with data from our database and aims to provide information on our experiences with tracheobronchial aspiration of FBs in children. PMID:28149578

    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.

    The majority of gastrointestinal (GI) foreign bodies (FBs) discovered in adults are the result of intentional ingestion, most of which are found in patients with a preexisting psychiatric illness, with substance abuse disorders, or in people seeking secondary gain. No similar case of internal injuries following unintentional ingestion of a barbecue grill cleaning brush bristle has been reported. A 58-year-old Caucasian male with no significant history presented with complaint of halitosis, not improving after oral care and dental hygiene measures. He denied any other symptoms. After ruling out oral causes of halitosis, an esophagogastroduodenoscopy was performed, which revealed a black wire-shaped metallic FB embedded in the duodenum. The FB was identified as a silver metallic flexible wire resembling the bristle of a barbecue grill cleaning brush. The halitosis resolved completely within 3 weeks of the removal of the FB. To the best of our knowledge, this is the first case of duodenal impaction of a barbecue grill cleaning brush bristle atypically presenting with halitosis. Physicians’ awareness of this potential injury from grill cleaning brush bristles would lead to a quick diagnosis after a focused history. Also avid grillers must be made aware of this potential hazard and should be encouraged to carefully examine the barbecue grill surface for any remnant bristle of the grill cleaning brush. Appropriate history taking, considering GI causes as potentially inducing halitosis, and an awareness of this entity among providers are important to facilitate prompt diagnoses and prevent major adverse outcomes.

    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.

    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.

    Although the primary etiological factor of periapical lesions is microbial, there are other independent factors that can adversely affect the outcome of endodontic treatment. In this communication, we present morphological evidence in support of the role of a foreign body reaction of periapical tissue to root-filling materials. The specimen consisted of a surgical biopsy of an asymptomatic periapical lesion which persisted after a decade of postendodontic follow-up. The biopsy was processed for correlated light and electron microscopy and was analyzed by various microtechniques. The unique feature of the lesion was the presence of vast numbers of large multinucleated cells and their cytoplasmic inclusion bodies. Morphologically, these multinucleated cells resembled foreign body giant cells. They contained characteristic birefringent cytoplasmic inclusions which on electron-probe x-ray microanalysis consistently revealed the presence of magnesium and silicon. The magnesium and silicon are presumably the remnants of a root-filling excess which protruded into the periapex and had been resorbed during the follow-up period. These observations strongly suggest that in the absence of microbial factors, root-filling materials which contain irritating substances can evoke a foreign body reaction at the periapex, leading to the development of asymptomatic periapical lesions that may remain refractory to endodontic therapy for long periods of time.

    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

    A 32-year-old female was admitted to our hospital with the chief complaint of vaginal discharge of urine. She had undergone radical hysterectomy due to uterine cancer at another hospital by a gynecologic surgeon 5 years earlier. X-ray examination showed a stone-like shadow at the left ureter without hydronephrosis. She was diagnosed with ureterovaginal fistula with the left ureteral stone. Left ureterolithotomy and ureterovesiconeostomy was performed. The stone revealed a foreign body stone originating from the silk worm-gut which had penetrated accidentally the ureter when the vaginal wall was sutured at the previous surgery. Including our case, 15 cases of foreign body stones in the upper urinary tract were found in the Japanese literature and none of them were associated with ureterovaginal fistula.

    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

    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.

    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±24μm for use as injectable cell carriers. Treatment with ethanolic sodium hydroxide for 2min 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 24h at 37°C was 0.9±0.1MPa, and the average Young's modulus was 9.4±1.2MPa. Scaffold porosity levels were 81.6% on average, with a mean pore diameter of 54±38μm. 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.

  13. Chemical and physical effects on the adhesion, maturation, and survival of monocytes, macrophages, and foreign body giant cells

    Collier, Terry Odell, III

    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

    Foreign body aspiration is still a cause of significant morbidity in children. Complications occur due to difficulty in diagnosis and treatment. An eight-year-old child presented with a history of recurrent cough for 3 days. Rigid bronchoscopy under general anesthesia revealed plastic bead occupying right main bronchus. Removal with grasping forceps failed for several times due to spherical, smooth, and large bead. Finally, Fogarty catheter was passed through bead under C-arm guidance and successfully removed.

    Objectives The aim of the study was to evaluate age, sex, breed, clinical signs, time between onset of signs and presentation, diagnostic procedures, method of extraction, location and nature of foreign bodies (FBs) in confirmed cases of tracheobronchial FBs in cats. We hypothesised that bronchoscopy was effective in extracting tracheobronchial FBs in cats. Methods A retrospective study was performed using clinical reports from three private practices in France between May 2009 and November 2014. Cats were included if an intraluminal tracheobronchial FB had been identified and extracted (either by bronchoscopy or surgery). Results Twelve cats (six male, six female) were included. Mean age was 3.75 ± 2.5 years. Coughing was the main complaint and was present in 9/12 (75%) of the cats. Thoracic radiographs were obtained in 12/12 cats (100%) and a FB was suspected in 11/12 (92%). Bronchoscopy was performed in all of the cats and enabled FB extraction in 10/12 (83%) of them. In 2/12 cats (17%), an additional surgical approach was required. In 6/12 (50%) cats, FBs were located in the trachea, while in 6/12 (50%) cats FBs were in the bronchial tree, particularly in the right caudal bronchus (4/6; 66%). Seven of 12 (58%) FBs were vegetal in nature, 3/12 (25%) were mineral and 2/12 (17%) were undetermined. All the mineral FBs were extracted from the trachea, while the majority of the vegetal ones (5/7; 71%) were found in the bronchi. Conclusions and relevance Feline respiratory FBs can be found in the trachea and in the bronchial tree, particularly in the right caudal bronchus. Vegetal FBs tend to migrate through the bronchial tree, whereas mineral ones tend to lodge in the trachea. Bronchoscopy seems to be a highly effective procedure for the extraction of tracheobronchial FBs in cats.

    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.

    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.

    Foreign body (FB) removal in our hospital was almost exclusively performed by surgeons through a rigid bronchoscope until the pulmonologists started getting involved in FB extraction. This study aimed to retrospectively review the results of 2 years of experience with 120 patients who presented or were referred to the Pulmonary Medicine Department, Ain Shams University Hospital in Cairo, Egypt, with clinical suspicion of FB aspiration during the period between December 2006 and December 2008. FBs were removed by either rigid and/or flexible bronchoscopy using either general or topical anesthesia. There were 54 male and 66 female patients with an age range between 3 months and 70 years and 68.5% of the patients were under the age of 10 years. Ninety patients (75%) presented with a definite history of FB aspiration, with a time interval between aspiration and presentation ranging between less than 6 hours and 12 months. The FB was visible on the chest x-ray in 42 cases. Aspirations were primarily into the right lung (53.2%). Seeds and scarf pins were the most common FB found, and were retrieved in 36 cases. Pulmonologists were successful in extracting 110 out of 111 (99.1%) bronchoscopically visualized FBs, and open thoracotomy was required in only 1 case for FB removal. In another 6 cases, only mucous plug was found to be the endogenous FB, whereas no FB could be found in 3 cases. No mortality or serious complications took place during or after the bronchoscopy. In conclusion, pulmonologists can extract FBs easily and safely either by using rigid and/or flexible bronchoscopes if they have the appropriate experience.

    A retrospective study was performed to determine the predisposing factors associated with the complications of ingested gastrointestinal (GI) tract foreign bodies (FBs) in children who had surgical or endoscopic removal. The study was performed in 161 children who had endoscopic or surgical removal. The clinical data were evaluated in two groups. In groups I and II, respectively, 135 patients with no complications and 26 patients with complications were analyzed. The relative risk analysis was performed for the risk factors. The number of the patients with an accurate history and the radiopaque FBs was significantly higher in group I. Metal, especially sharp objects, and food plugs obstructing a diseased esophagus were the most common FBs found in group II. The majority of the FBs of both groups were entrapped in esophagus, the number of the FBs distal to esophagus was significantly higher and duration of lodgment was significantly longer in group II. Esophageal abrasion, laceration and bleeding, complete esophageal obstruction, caustic injury, severe esophageal stricture, laryngeal edema, recurrent aspiration pneumonia, loss of weight, intestinal perforation, constipation and intestinal obstruction were determined as complications. The relative risk was >1 for duration of lodgment more than 24 h, for sharp or pointed objects, button batteries, nonopaque objects, diseased esophagus and for the objects located below the upper third of esophagus. Type, radiopacity, location and duration of the ingested GI tract FB determine the outcome. A delayed diagnosis is the most significant factor increasing the risk of complications. Physician must maintain a high index of suspicion and a more extensive history; physical examination and radiodiagnostic investigation should be obtained in suspected cases.

    Recently, iatrogenic foreign-body granuloma has been increasingly reported. The asymptomatic presentation and confusing appearance of granuloma can lead to misdiagnosis of a secondary malignancy, especially for a patient with a corresponding past medical history. Sometimes, surgical treatment is unavoidable, and the diagnosis relies upon the pathologic result. Herein, we report an unusual case of a 43-year-old man who underwent a nephrectomy for renal cell carcinoma (clear cell type) 5 years ago. A secondary granuloma was identified behind the inferior vena cava in the retroperitoneum 6 months after the surgery, but the radiologists had failed to identify it throughout the 4 years of routine examination. Later on, the lesion was identified by positron emission tomography, which classified it as a highly 18F-fluorodeoxyglucose-avid lesion. Considering no visible foreign-bodies identified on images, the lesion was arguably diagnosed as a lymph node metastasis of renal cancer. Finally, it was confirmed as a foreign-body granuloma encasing surgical suture and adipose tissue by the pathological analysis. PMID:25429231

    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.

    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.

    AIM: To determine the utility of X-ray in identifying non-metallic foreign body (FB) and assess inter-radiologist agreement in identifying non-metal FB. METHODS: Focus groups of nurses, fellows, and attending physicians were conducted to determine commonly ingested objects suitable for inclusion. Twelve potentially ingested objects (clay, plastic bead, crayon, plastic ring, plastic army figure, glass bead, paperclip, drywall anchor, eraser, Lego™, plastic triangle toy, and barrette) were embedded in a gelatin slab placed on top of a water-equivalent phantom to simulate density of a child’s abdomen. The items were selected due to wide availability and appropriate size for accidental pediatric ingestion. Plain radiography of the embedded FBs was obtained. Five experienced radiologists blinded to number and types of objects were asked to identify the FBs. The radiologist was first asked to count the number of items that were visible then to identify the shape of each item and describe it to a study investigator who recorded all responses. Overall inter-rater reliability was analyzed using percent agreement and κ coefficient. We calculated P value to assess the probability of error involved in accepting the κ value. RESULTS: Fourteen objects were radiographed including 12 original objects and 2 duplicates. The model’s validity was supported by clear identification of a radiolucent paperclip as a positive control, and lack of identification of plastic beads (negative control) despite repeated inclusion. Each radiologist identified 7-9 of the 14 objects (mean 8, 67%). Six unique objects (50%) were identified by all radiologists and four unique objects (33%) were not identified by any radiologist (plastic bead, Lego™, plastic triangle toy, and barrette). Identification of objects that were not present, false-positives, occurred 1-2 times per radiologist (mean 1.4). An additional 17% of unique objects were identified by less than half of the radiologists

    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%.

    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.

    Background: Intracerebral foreign body granuloma is rarely reported. We present the case of a male patient with a cerebral foreign body granuloma. Case Description: Initial admission of a 67-year-old male patient was after an aphasia followed by secondary generalized seizures. Cranial computed tomography (CCT) showed a metal-dense, wedge-shaped foreign body in the range of the frontal sinus on the left side, breaking through the frontal sinus, and creating a connection to the frontal cerebral lobe. The patient did not report previous trauma or accident. A concomitant inflammatory response could not be excluded in CCT imaging. In clinical examination, the patient showed no sensorimotor deficit. Operative resection and dural reconstruction was performed. Several tiny, metal-like foreign-body fragments and one stone-like body could be detected and removed. Histopathological examination showed an intracerebral granuloma with areas of acute granulocytic inflammatory reaction. Conclusion: Cerebral foreign body granuloma is a rare entity without initially provoking clinical symptoms, and causing clinical symptoms even years after the initial event. In most reported cases, wooden or metallic bodies are reported. In addition, hemostatic materials and non-resorbable cotton sheets can cause intracerebral granuloma. There is a high risk of infection with a high mortality rate in case of an existent intracranial abscess. In case of first presentation of seizures, a foreign body should be kept in mind if a traumatic injury cannot be reported. Therefore, possible foreign bodies provoking clinical symptoms such as seizures should always be radiologically excluded, and if present and operatively accessible, removal should be done as soon as possible.

    Serotonin is known to inhibit food and water intake. However, the effect of its injection into nucleus caudatus on food and water intake is not known. In the present study, serotonin hydrochloride, buspirone (the serotonin 5-HT1A agonist) and ondensetron (the 5HT3 antagonist) were injected into nucleus caudatus through stereotaxically implanted cannulae in three different dosages (1, 2 and 5 microg) and their effects on 24 h food and water intake, and body weight were recorded. The injection of serotonin hydrochloride resulted in a dose- dependent decrease in food intake attaining maximum of 27.3% at 5 microg dose, whereas water intake and body weight were decreased 12% and 4.3% respectively only at the highest does. Buspirone elicited a dose dependent inhibition of food and water intake and body weight (22.3%, 19.8% and 5.1% respectively), whereas ondensetron elicited an increase in food and water intake (37.8% and 36.3% respectively) without significantly altering bodyweight. It was concluded that serotonin hydrochloride injected into nucleus caudatus inhibits food and water intake significantly. These effects are mediated via 5-HT1A and 5HT3 receptors. The effect of injections of 5-HT1A receptor agonist is more pronounced on water intake. The effect of injections of 5HT3 receptor antagonist is also more pronounced on water intake.

    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

    The multfactorial nature of bone injuries in modern warfare and emergency trauma patients warrants enhancement of existing models. To develop a more appropriate model, rat tibiae (n = 195) were mechanically injured, divided into 2 groups (with or without thermal injury), and contaminated with a range of Staphylococcus aureus (Cowan 1) inocula. In some experiments, S. aureus inocula also contained Escherichia coli or foreign bodies (sand or soil). The primary outcome measure was the amount of S. aureus remaining in the tibia (tibial bacterial load) 24 h after contamination, reported as log10 cfu/g bone. S. aureus showed ID50 and ID95 values of 72 and 977 cfu, respectively. Values were lower than seen previously by using S. aureus strain SMH. S. aureus tibial bacterial loads were higher in tibiae with mechanical and thermal injury (log10 4.15 +/- 0.27 cfu/g) versus mechanical injury alone (log10 3.1 +/- 0.47 cfu/g, P = 0.028). The addition of E. coli to the S. aureus inoculum had no effect on tibial bacterial loads (S. aureus only, log10 4.24 +/- 0.92 cfu/g; S. aureus + E. coli, log10 4.1 +/- 1.0 cfu/g, P = 0.74). Sand, added as a foreign body, increased tibial bacterial load. Combined mechanical and thermal trauma of the tibia is associated with increased S. aureus tibial bacterial loads, increasing the risk of acute osteomyelitis. Understanding the interplay of mechanical and thermal injuries, bimicrobial contamination, and foreign bodies may improve our understanding of traumatic bone injuries and the pathogenesis of osteomyelitis.

    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.

    Eye injuries are common in forward areas of operations. Definitive diagnosis and care may be limited not by provider skill but rather by available equipment. The ability to treat simple trauma such as corneal foreign bodies at the Role 1 level has advantages including rapid return to duty, decreased cost of treatment, and, most important, decreased risk of delayed care. We propose the device such as a hand-held portable slit lamp should be made available for appropriate Special Operations Medical Forces (SOFMED) or aviation providers.

    Ingested or penetrating foreign bodies are common in veterinary medicine. When they are radiolucent, these objects become a diagnostic challenge, but they can be investigated sonographically. However, successful object identification depends on the skill of the sonographer. Considering that these cases appear randomly during hospital routines, it is not always possible to train all students to identify them correctly. Therefore, the aim of this study was to produce homemade simulations of radiolucent foreign bodies for veterinary student demonstrations that could be identified sonographically and to evaluate the acceptability, applicability, and usefulness of these simulations according to a visual analog scale questionnaire and subjective questions. For this purpose, object models (a pacifier nipple, a toy ball, a sock, nylon thread, and a mango seed) were designed, produced, and immersed in gelatin. To simulate wood splinters in the integumentary and musculoskeletal system, a piece of meat punctured with a toothpick and ice cream stick splinters were used. The type of phantom had a determinant effect on the visualization (chi-square = 36.528, P < 0.0001) and recognition (chi-square = 18.756, P = 0.0021) capability of the students. All of the students answered that their experience with the models could help in real situations. The student responses to the questionnaire indicated that the project was well accepted, and the participants believed that this experience could be applicable to and useful in veterinary routines.

  17. A peculiar case of a retained inert piece of fireworks as an intraocular foreign body in the anterior chamber.

    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.

    Prosthetic reinforcements markedly reduce the risk of hernia recurrence. However, the implantation of meshes is related to an inflammatory foreign body reaction (FBR) with serious complications (i.e., persistent seroma, wound infection, mesh migration, entrapment, chronic pain). Adrenal hormones profoundly modify inflammatory response. Their effects on FBR however, remain ill defined. We therefore studied the FBR to polyvinylidenfluoride (PVDF) mesh material that was coated with four different substances: hydrocortisone (COR) or mifepristone (MIF), which respectively stimulate and block the glucocorticoid receptor, and aldosterone (ALD) or spironolactone (SPI), which respectively stimulate and block the mineralocorticoid receptor. The coated substances were released from the meshes within 24 h. Seven, 21, and 90 days after implantation, the specimen was evaluated for collagen formation, granuloma size, inflammatory activity, and angiogenesis. COR and SPI coating protected from inflammatory response, while ALD and MIF coating showed little difference to the control group. The COR and SPI groups showed smaller granuloma sizes at all time points, as well as a reduced number of inflammatory cells (p < 0.001) at day 90, and decreased collagen formation starting after 21 days (p < 0.05). There was a negative correlation for angiogenesis with inflammation around foreign body structures. In summary, these results suggest that early and temporary stimulation of the glucocorticoid receptor or blockade of the mineralocorticoid receptor have beneficial effects on FBR in the long term.

  19. Detection of Foreign Bodies and Bubble Defects in Tire Radiography Images Based on Total Variation and Edge Detection

    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.

    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.

    Implantation of sterile foreign objects in the peritoneal cavity of an animal initiates an inflammatory response and results in encapsulation of the objects by bone marrow-derived cells. Over time, a multilayered tissue capsule develops with abundant myofibroblasts embedded in extracellular matrix. The present study used the transgenic MacGreen mouse to characterize the time-dependent accumulation of monocyte subsets and neutrophilic granulocytes in the inflammatory infiltrate and within the tissue capsule by their differential expression of the csf1r-EGFP transgene, F4/80, and Ly6C. As the tissue capsule developed, enhanced green fluorescent protein-positive cells changed from rounded to spindle-shaped morphology and began to co-express the myofibroblast marker alpha-smooth muscle actin. Expression increased with time: at day 14, 11.13 +/- 0.67% of tissue capsule cells co-expressed these markers, compared with 50.77 +/- 12.85% of cells at day 28. The importance of monocyte/macrophages in tissue capsule development was confirmed by clodronate-encapsulated liposome removal, which resulted in almost complete abrogation of capsule development. These results confirm the importance of monocyte/macrophages in the tissue response to sterile foreign objects implanted in the peritoneal cavity. In addition, the in vivo plasticity of peritoneal macrophages and their ability to transdifferentiate from a myeloid to mesenchymal phenotype is demonstrated.

    In the food industry there is an ever increasing need to control and monitor food quality. In recent years fully automated x-ray inspection systems have been used to detect food on-line for foreign body contamination. These systems involve a complex integration of x- ray imaging components with state of the art high speed image processing. The quality of the x-ray image obtained by such systems is very poor compared with images obtained from other inspection processes, this makes reliable detection of very small, low contrast defects extremely difficult. It is therefore extremely important to optimize the x-ray imaging components to give the very best image possible. In this paper we present a method of analyzing the x-ray imaging system in order to consider the contrast obtained when viewing small defects.

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.

    In computed tomographic (CT) scans, a wooden foreign body can appear as a lucency with nearly the same density as air or fat, and it can be indistinguishable from orbital adipose tissue. Magnetic resonance imaging (MRI) can localize these wooden foreign bodies in the orbit. We studied a case in which a wooden golf tee lodged in the right optic canal of a nine-year-old boy. The head portion lodged in the orbital apex and the tip entered the interpeduncular fossa. Clinical examination revealed a right paranasal laceration; the right eye had no light perception and a peripapillary hemorrhage, but was otherwise normal. Surgical exploration and evaluation by CT failed to locate the foreign body. However, the golf tee was demonstrated by MRI as a low intensity image. Although it was removed by craniotomy with good neurological results, bacterial panophthalmitis led to enucleation of the eye. This case emphasizes the diagnostic value of MRI and the hazards of retained wooden foreign bodies.

    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.

    For enterococcal implant-associated infections, the optimal treatment regimen has not been defined. We investigated the activity of daptomycin, vancomycin, and gentamicin (and their combinations) against Enterococcus faecalis in vitro and in a foreign-body infection model. Antimicrobial activity was investigated by time-kill and growth-related heat production studies (microcalorimetry) as well as with a guinea pig model using subcutaneously implanted cages. Infection was established by percutaneous injection of E. faecalis in the cage. Antibiotic treatment for 4 days was started 3 h after infection. Cages were removed 5 days after end of treatment to determine the cure rate. The MIC, the minimal bactericidal concentration (MBC) in the logarithmic phase, and the MBC in the stationary phase were 1.25, 5, and >20 μg/ml for daptomycin, 1, >64, and >64 μg/ml for vancomycin, and 16, 32, and 4 μg/ml for gentamicin, respectively. In vitro, gentamicin at subinhibitory concentrations improved the activity against E. faecalis when combined with daptomycin or vancomycin in the logarithmic and stationary phases. In the animal model, daptomycin cured 25%, vancomycin 17%, and gentamicin 50% of infected cages. In combination with gentamicin, the cure rate for daptomycin increased to 55% and that of vancomycin increased to 33%. In conclusion, daptomycin was more active than vancomycin against adherent E. faecalis, and its activity was further improved by the addition of gentamicin. Despite a short duration of infection (3 h), the cure rates did not exceed 55%, highlighting the difficulty of eradicating E. faecalis from implants already in the early stage of implant-associated infection.

    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.

    Risk Assessment is the systematic study of decisions subject to uncertain consequences. An increasing interest has been focused on modeling techniques like Bayesian Networks since their capability of (1) combining in the probabilistic framework different type of evidence including both expert judgments and objective data; (2) overturning previous beliefs in the light of the new information being received and (3) making predictions even with incomplete data. In this work, we proposed a comparison among Bayesian Networks and other classical Quantitative Risk Assessment techniques such as Neural Networks, Classification Trees, Random Forests and Logistic Regression models. Hybrid approaches, combining both Classification Trees and Bayesian Networks, were also considered. Among Bayesian Networks, a clear distinction between purely data-driven approach and combination of expert knowledge with objective data is made. The aim of this paper consists in evaluating among this models which best can be applied, in the framework of Quantitative Risk Assessment, to assess the safety of children who are exposed to the risk of inhalation/insertion/aspiration of consumer products. The issue of preventing injuries in children is of paramount importance, in particular where product design is involved: quantifying the risk associated to product characteristics can be of great usefulness in addressing the product safety design regulation. Data of the European Registry of Foreign Bodies Injuries formed the starting evidence for risk assessment. Results showed that Bayesian Networks appeared to have both the ease of interpretability and accuracy in making prediction, even if simpler models like logistic regression still performed well.

    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.

    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.

  1. A problem-solving approach to effective insulin injection for patients at either end of the body mass index.

    People with diabetes require skills and knowledge to adhere to medication regimens and self-manage this complex disease. Effective self-management is contingent upon effective problem solving and decision making. Gaps existed regarding useful approaches to problem solving by individuals with very low and very high body mass index (BMI) who self-administer insulin injections. This article addresses those gaps by presenting findings from a patient survey, a symposium on the topic of problem solving, and recent interviews with diabetes educators to facilitate problem-solving approaches for people with diabetes with high and low BMI who inject insulin and/or other medications. In practice, problem solving involves problem identification, definition, and specification; goal and barrier identification are a prelude to generating a set of potential strategies for problem resolution and applying these strategies to implement a solution. Teaching techniques, such as site rotation and ensuring that people with diabetes use the appropriate equipment, increase confidence with medication adherence. Medication taking is more effective when people with diabetes are equipped with the knowledge, skills, and problem-solving behaviors to effectively self-manage their injections.

    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

    Background Foreign body aspiration (FBA) is a potentially life-threatening condition in children, and removal of an aspirated bead can be difficult. Case Report An 11-month-old male infant presented with a history of choking 6 days prior to admission. FBA was suspected, and initial examination revealed a bead occluding the left main bronchus. The surgeon tried to retrieve the foreign body, but the patient developed coughing episodes with desaturation. The patient was intubated and a bronchoscopy was performed with a flexible bronchoscope. A Fogarty catheter was passed through the bronchoscope and then advanced through the bead opening. The distal balloon was inflated, and the bead was removed as the Fogarty catheter was withdrawn. Conclusion We successfully removed an aspirated bead from an infant using the passing-through technique with a Fogarty catheter. Maintaining spontaneous ventilation for as long as possible and good coordination between the anesthesiologist and surgeon are crucial in such cases. PMID:25829892

    A statistical study of 41 cases with denture foreign bodies in the air and upper food passages which were treated in our department during the past 21 years was done. (1) Males were more frequently affected. The ratio of male to female was about 2 to 1. (2) Of 41 dentures, 2, 2 and 37 were lodged in the air passages, hypopharynx and esophagus respectively. (3) There were 5 complete mandibular dentures in 41 cases. (4) The causes of the denture foreign bodies were originated to the problem of denture itself in 29 cases, that of the patient himself in 2 cases and both in 10 cases. (5) Of 39 problematic dentures, 16 showed the breakage such as plate fracture and clasp deformity, but the other 23 showed no breakage. In this latter group, poor holding of the denture was ascribed to miss-making or miss-planning. (6) Of 12 patients with problems in their physical function, 5 had suffered from cerebrovascular disease and 3 from geriatric dementia. (7) The denture foreign body in aged patients with physical hypofunction tends to increase in recent years. (8) Of 39 dentures tried to remove by esophagoscopy, 18 were done with difficulty and they were detachable partial dentures with one artificial tooth and 2-arm-clasps lodged at the first and/or second isthmus of the esophagus. Though we have a denture removed successfully at the third trial, we have no case needed external esophagotomy. (9) Duplicated denture models were made in 20 cases prior to the procedure, and we certify that these models play an important role for the safer removal of denture foreign bodies.

    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.

    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.

  8. Isiris: A Novel Method of Removing Foreign Bodies from the Lower Urinary Tract to Avoid Unnecessary Hospitalization and Anesthesia

    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

    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.

    The present case shows a case of progression of osteolysis of the greater trochanter caused by a foreign body granuloma associated with the number 5 Ethibond suture in cementless THA with the direct lateral approach that was completely healed by removal of the Ethibond suture. A 55-year-old Japanese woman with secondary osteoarthritis caused by acetabular dysplasia underwent left cementless THA with the direct lateral approach. After setting of the total hip prosthesis, the gluteus medius muscle and vastus lateralis muscle were reattached to the greater trochanter through two bone tunnels using number 5 Ethibond EXCEL sutures. The left hip pain disappeared after surgery, but the bone tunnels enlarged gradually and developed osteolysis at 10 weeks. The removal of the Ethibond sutures and debridement improved the osteolysis. Histological examination showed the granuloma reaction to a foreign body with giant cell formation. The Ethibond suture has the lowest inflammatory tissue reaction and relatively high tension strength among nonabsorbable suture materials. However, number 5 Ethibond has the potential to cause osteolysis due to a foreign body granuloma, as in the present case. PMID:28255486

    In this study, the efficacy of ceftaroline versus vancomycin against biofilm-producing methicillin-resistant Staphylococcus epidermidis (MRSE) in a murine model of foreign-body and systemic infection was compared. Two bacteraemic biofilm-producing MRSE strains were used (SE284 and SE385). The minimum inhibitory concentrations (MICs) for strains SE284 and SE385, were, respectively, 0.25 mg/L and 0.5 mg/L for ceftaroline and 4 mg/L and 2 mg/L for vancomycin. The in vitro bactericidal activities of ceftaroline and vancomycin were evaluated using time-kill curves. A foreign-body and systemic infection model in neutropenic female C57BL/6 mice was used to ascertain in vivo efficacy. Animals were randomly allocated into three groups (n = 15) without treatment (controls) or treated with ceftaroline 50 mg/kg every 8 h or vancomycin 110 mg/kg every 6 h. In vitro, ceftaroline showed concentration-dependent bactericidal activity, whilst vancomycin presented time-dependent activity. In the experimental in vivo model, ceftaroline and vancomycin decreased the liver and catheter bacterial concentrations (P <0.05) and increased survival (P <0.05) for both strains. In conclusion, ceftaroline is as effective as vancomycin in the treatment of experimental foreign-body and systemic infection caused by biofilm-producing MRSE.

    Purpose To report a case of combined laparoscopic and carbon dioxide partial cystectomy and foreign body removal and to review the existing literature on the topic. Materials and Methods A 43-year-old Asian woman was found to have an intrauterine device embedded in the bladder wall during evaluation for chronic pelvic pain and urinary tract infection. She underwent cystoscopic-laparoscopic partial cystectomy, with an uncomplicated postoperative course. She had normal renal function during the follow-up period. This case demonstrates the possibility and safety of performing cystoscopic-laparoscopic partial cystectomy for the removal of a partially implanted intravesical foreign body. Results The patient recovered without incident and was discharged 7 days after surgery. No abnormalities were noted in the urine output or renal function in the postoperative follow-up period. No complications due to retrograde flow of carbon dioxide up the ureters or air embolism were noted during the procedure or postoperatively. Conclusions The combination of laparoscopy and air cystoscopy has been shown to be an optimal method for retracting foreign bodies embedded in the bladder wall. Also, air cystoscopy can be used to give doctors a better view in cases in which vision is compromised under water-contrast cystoscopy. PMID:27847920

    Summary: In the pursuit of success in sports, some athletes are not deterred by health risks associated with the (mis)use of black market preparations of dubious origin as performance-enhancing agents. Several studies published in the recent years demonstrated that anabolic-androgenic steroids, but also stimulants and growth hormones, are misused by numerous recreational athletes from all over the world. Trenbolone is an anabolic steroid routinely used in the finishing phase of beef production to improve animal performance and feed efficiency. A 35-year-old male patient presented to our plastic surgery clinic after self-intramuscular administration of Trenbolone to the superior gluteal area bilaterally, which led to a full-thickness defect in a cone-like distribution. The wounds underwent surgical debridement and were treated locally with mafenide acetate irrigation and wound dressings. Closure was achieved by secondary intention healing. In this report, we discuss the first documented case of full-thickness skin and subcutaneous tissue necrosis after black market anabolic steroid injection. This illustrates a plastic complication and resolution of a widespread but seldom reported problem. PMID:27757350

  16. Many-body effects and self-contained phase dynamics in an optically injected quantum-dot laser

    2012-06-01

    Quantum-dot (QD) lasers exhibit unique properties when subjected to optical injection, e.g. lower sensitivity and less complex dynamics when compared to conventional quantum-well (QW) lasers. These features can be explained by a lower phase-amplitude coupling and a higher damping of relaxation oscillations in QD laser devices. In this work, we investigate an optically injected QD laser and clarify the role of many-body effects. We model the QD laser device using a semi-classical approach based on the semiconductor-Bloch and Maxwell's equations. The QD optical transition is modeled with a finite spectral width, accounting for inhomogeneous broadening due to QD imperfections. Furthermore, many-body Coulomb interactions, leading to renormalizations of the single-particle energies, are taken into account assuming the screened Hartree-Fock approximation. Throughout the literature the phase dynamics of the electric field inside the laser cavity is implemented by assuming a constant α-factor. Our model accounts for the effects of α via a more rigorous treatment of light-semiconductor interaction. As a result the model allows to extract a value for the α-factor from the intrinsic phase dynamics of the system. The extracted α-factor is not a constant, but rather changes on the one hand dynamically throughout the simulations, and on the other hand with all operation conditions. Furthermore, the dynamical shift of the band-gap energy due to the Coulomb interactions gives rise to modifications in the locking behavior of the laser, that can not be explained with the simpler free-carrier models.

    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.

  18. The effect of stratification on premixed swirl-flame flashback by using porous center-body injection

    Boundary layer flashback must be prevented in order to stably operate stationary gas turbines. One strategy to avoid flashback is to create equivalence-ratio stratification, such as by reducing the fuel/air ratio in the boundary layer below the flammability limit. Typically, stratification is achieved by using radially non-uniform fuel injection. The goal of the current study is to reduce the propensity of flashback in a premixed annular swirl combustor that uses a premix section with center-body. A porous metal center-body (10 micron pore size) is used to bleed air directly into the boundary layer and thus locally reduce the equivalence ratio. Planar laser-induced fluorescence imaging of anisole-seeded flow is carried out to assess the stratification in the flow. Time-resolved PIV and chemiluminescence imaging are used to investigate flashback at atmospheric pressure conditions. A comparative study between fully premixed and stratified flame flashback is conducted to determine how stratification influences flashback physics.

    Galanin-Like Peptide (GALP) is a hypothalamic neuromediator of metabolism and reproduction. GALP is known to stimulate reproduction and alter food intake and body weight in multiple species. The regulation of body weight involves control of both energy intake and energy expenditure. Since GALP is known to alter food intake - possibly via the autonomic nervous system - we first hypothesized that GALP would increase metabolic rate. First, male Sprague-Dawley rats were implanted with intracerebroventricular (ICV) cannulae and abdominal radiotelemetry temperature transmitters. Following ICV injection with either 5nmol GALP or vehicle, the oxygen consumption of each rat was monitored for 8h. Food intake, core temperature, and general motor activity were monitored for 24h. GALP significantly increased oxygen consumption, an indirect estimator of metabolic rate, without having any significant effect on motor activity. Compared to controls, GALP increased core body temperature during the photophase and reduced food intake over the 24h period following injection. ICV GALP also increased plasma levels of luteinizing hormone (LH). A second group of male Sprague-Dawley rats were implanted with abdominal transmitters and given injections of GALP directly into the nucleus of the tractus solitarius (NTS). These injections resulted in a significant reduction in food intake, and a significant increase in both oxygen consumption and core body temperature compared to vehicle injections. Direct injections of GALP into the NTS compared to vehicle also resulted in a significant increase in plasma leptin levels, but not LH levels. GALP appears to increase energy expenditure in addition to decreasing energy input by actions within the NTS and thus may play an important role in the hypothalamic regulation of body weight.

    A prospective randomized double-blind clinical study was performed to investigate corneal wound healing after treatment either with an eye gel containing calf blood extract or an eye ointment containing vitamin A and dexpanthenol. A total of 54 outpatients were included in this study, all treated for corneal foreign body injury. The size of the corneal lesions was measured by planimetry on days 0, 1, and on the following days until complete epithelial healing occurred. Results showed the calf blood extract eye gel to be statistically more effective in promoting corneal wound healing, especially in patients with wound areas larger than 6 mm(2).

    The management of intravascular metallic foreign bodies (FB) can be difficult and challenging. We report a case of a migrating FB, initially within the femoral vein which subsequently migrated to the intrahepatic vena-cava. Following a change of posture, the metallic FB moved with gravity against the normal venous blood flow to the left renal vein. It was finally fixed in position in a peripheral branch of the renal vein using an intravascular stent. Employing gravity as a therapeutic intervention and the technique used in isolating the FB has not, to our knowledge, been reported before. A case is described, and the literature is reviewed.

    The effect of Solcoseryl on the healing rate of corneal lesions after foreign body removal was assessed in a double-blind study. Solcoseryl is a protein-free hemodialysate which is widely used to stimulate tissue repair processes. The healing rate was determined by means of photodocumentation which was complete in 82 out of 92 cases. The Solcoseryl group showed in significantly faster healing rate and a lower tendency to development of corneal opacities than the control group. No side-effects were observed which could be attributed to either of the drugs used in the study.

    In this study, our purpose was to investigate the possible effect of paternal obesity on intracytoplasmic sperm injection (ICSI) outcomes on the basis of clinical pregnancy outcome. Antropometric measurements of 155 couples, referred to our infertility clinic and who underwent an ICSI cycle, have been evaluated. The study sample were divided into three groups with respect to paternal body mass index (BMI), as normal weight (BMI: 20-24.9), overweight (BMI: 25-29.9) and obese (BMI ≥ 30). Results of conventional semen analysis were also analysed. Clinical pregnancy data, including fertilisation rate, implantation rate, clinical pregnancy rate and live birth rate, were evaluated. Paternal obesity was a significant negative factor for sperm concentration and sperm motility (P = 0.03 and P = 0.01 respectively). A significant decrease of clinical pregnancy rate and live birth rate was associated with increased paternal BMI (P = 0.04 and P = 0.03 respectively). We have not determined a significant difference among groups in terms of fertilisation rate and implantation rate. This study demonstrates that increasing paternal BMI has a negative influence on ICSI success, including clinical pregnancy rate and live birth rate. There is a need for further studies to point the importance of lifestyle changes in order to overcome the negative influence of paternal obesity on couple's fertility.

  12. The role of collagen receptors Endo180 and DDR-2 in the foreign body reaction against non-crosslinked collagen and gelatin.

    Despite the use of collagen-derived scaffolds in regenerative medicine, little is known about the degradation mechanisms of these scaffolds in vivo. Non-crosslinked dermal sheep (NDSC) and gelatin disks were implanted subcutaneously in mice. NDSC disks showed a very low degradation rate, despite the presence of high numbers of macrophages and the influx of neutrophils. This was attributed to the presence of the matrix metalloproteinase inhibitor TIMP-1. The limited degradation occurred mainly in the later stages of the foreign body reaction, and could be attributed to (1) phagocytosis by macrophages due to a co-expression of Endo180 and MT1-MMP on these cells (intracellular degradation) and (2) the presence of MMP-13 due to an upregulation of the expression of the DDR-2 receptor (extracellular degradation). In contrast, gelatin disks degraded quickly, due to the efficient formation of large giant cells as well as the presence of MMP-13; the inhibitor TIMP-1 was absent. The DDR-2 receptor was not expressed in the gelatin disks. Endo180 and MT1-MMP were expressed, but at most times no co-expression was seen. We conclude that the physical state of collagen (native or denatured) had a dramatic outcome on the degradation rate and provoked a completely different foreign body reaction.

    Modulation of the foreign body reaction is considered to be an important step toward creation of implanted sensors with reliable long-term performance. In this work, microdialysis probes were implanted into the subcutaneous space of Sprague-Dawley rats. The probe performance was evaluated by comparing collected endogenous glucose concentrations with internal standard calibration (2-deoxyglucose, antipyrine, and vitamin B12). Probes were tested until failure, which for this work was defined as loss of fluid flow. In order to determine the effect of fibrous capsule formation on probe function, monocyte chemoattractant protein-1/CC chemokine ligand 2 (MCP-1/CCL2) was delivered locally via the probe to increase capsule thickness and dexamethasone 21-phosphate was delivered to reduce capsule thickness. Probes delivering MCP-1 had a capsule that was twice the thickness (500–600 μm) of control probes (200–225 μm) and typically failed 2 days earlier than control probes. Probes delivering dexamethasone 21-phosphate had more fragile capsules and the probes typically failed 2 days later than controls. Unexpectedly, extraction efficiency and collected glucose concentrations exhibited minor differences between groups. This is an interesting result in that the foreign body capsule formation was related to the duration of probe function but did not consistently relate to probe calibration. PMID:21722577

    Surgicel® (Ethicon, North Ryde, NSW, Australia) is an absorbable sheet of oxidized cellulose polyanhydroglucuronic acid polymer used as an hemostatic in cardiovascular and thoracic surgery. In some cases, the retained material may cause foreign body granulomatous reactions and simulate tumor recurrence, an abscess, an hematoma, or an infection. We report the case of a 55-year-old patient who was operated of a lung adenocarcinoma. In the thoracic computed tomography scan 1 year after the surgery, a right paratracheal lymph node was detected, so endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was performed suspecting recurrence of the tumor. The cytology results of the lymph node showed a nonnecrotizing granulomatous reaction secondary to Surgicel®, used as an hemostatic during the surgery. The objective of presenting this case is to consider foreign body reaction to Surgicel® in the differential diagnosis of postoperative suspicion of neoplastic recurrence, and on the other hand, to note that EBUS-TBNA enables diagnosis.

    Orthopedic foreign body-associated infections are often treated with rifampin-based combination antimicrobial therapy. We previously observed that rifampin-resistant and methicillin-resistant Staphylococcus aureus (MRSA) isolates were present 2 days after cessation of rifampin therapy in experimental foreign body osteomyelitis. Unexpectedly, only rifampin-susceptible isolates were detected 14 days after the completion of treatment. We studied two rifampin-resistant isolates recovered 2 days after treatment and one rifampin-susceptible isolate recovered 14 days after treatment. Growing these isolates alone in vitro or in vivo demonstrated no fitness defects; however, in mixed culture, rifampin-susceptible bacteria outcompeted rifampin-resistant bacteria. In vivo, two courses of rifampin treatment (25 mg/kg of body weight every 12 h for 21 days) yielded a greater decrease in bacterial quantity in the bones of treated animals 14 days following treatment than that in animals receiving a single course of treatment (P = 0.0398). In infections established with equal numbers of rifampin-resistant and rifampin-susceptible bacteria, one course of rifampin treatment did not affect bacterial quantities. Rifampin-resistant and rifampin-susceptible isolates were recovered both 2 days and 14 days following treatment completion; however, the proportion of animals with rifampin-resistant isolates was lower at 14 days than that at 2 days following treatment completion (P = 0.024). In untreated animals infected with equal numbers of rifampin-resistant and rifampin-susceptible bacteria for 4 weeks, rifampin-susceptible isolates were exclusively recovered, indicating the outcompetition of rifampin-resistant by rifampin-susceptible isolates. The data presented imply that although there is no apparent fitness defect in rifampin-resistant bacteria when grown alone, they are outcompeted by rifampin-susceptible bacteria when the two are present together. The findings also suggest that

    Combined positron emission tomography/computed tomography (PET/CT) using the glucose analogue 2-[18F]-fluoro-2-deoxy-D-glucose (FDG) has become the standard of care in oncological patients. However, due to the non-specific nature of FDG uptake, there are many physiological variants and benign pathological entities that also demonstrate augmented glucose metabolism, such as inflammatory and infective processes. Undiagnosed and retained foreign bodies (occult foreign bodies) in the lung can induce inflammatory reaction consisting of polymorphonuclear neutrophils, macrophages, and granulation tissue resulting in intense FDG uptake because of high metabolic activity and cell turnover. Here, we present a case of an occult foreign body imitating a tumor on PET/CT.  PMID:28265526

  17. Long-term sustained release of salicylic acid from cross-linked biodegradable polyester induces a reduced foreign body response in mice.

    There has been a continuous surge toward developing new biopolymers that exhibit better in vivo biocompatibility properties in terms of demonstrating a reduced foreign body response (FBR). One approach to mitigate the undesired FBR is to develop an implant capable of releasing anti-inflammatory molecules in a sustained manner over a long time period. Implants causing inflammation are also more susceptible to infection. In this article, the in vivo biocompatibility of a novel, biodegradable salicylic acid releasing polyester (SAP) has been investigated by subcutaneous implantation in a mouse model. The tissue response to SAP was compared with that of a widely used biodegradable polymer, poly(lactic acid-co-glycolic acid) (PLGA), as a control over three time points: 2, 4, and 16 weeks postimplantation. A long-term in vitro study illustrates a continuous, linear (zero order) release of salicylic acid with a cumulative mass percent release rate of 7.34 × 10(-4) h(-1) over ∼1.5-17 months. On the basis of physicochemical analysis, surface erosion for SAP and bulk erosion for PLGA have been confirmed as their dominant degradation modes in vivo. On the basis of the histomorphometrical analysis of inflammatory cell densities and collagen distribution as well as quantification of proinflammatory cytokine levels (TNF-α and IL-1β), a reduced foreign body response toward SAP with respect to that generated by PLGA has been unambiguously established. The favorable in vivo tissue response to SAP, as manifest from the uniform and well-vascularized encapsulation around the implant, is consistent with the decrease in inflammatory cell density and increase in angiogenesis with time. The above observations, together with the demonstration of long-term and sustained release of salicylic acid, establish the potential use of SAP for applications in improved matrices for tissue engineering and chronic wound healing.

    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.

    Long-term selection for juvenile body weight from a common founder population resulted in two divergent chicken lines (low-weight selected line (LWS), high-weight selected line (HWS)) that display distinct food intake and blood glucose responses to exogenous neuropeptides and insulin. The objective of this study was to elucidate putative targets affecting food intake and energy homeostasis by sequencing hypothalamic RNA from LWS and HWS chickens after insulin injection. Ninety-day-old female LWS and HWS chickens were injected with either vehicle or insulin and hypothalamus collected at 1 h postinjection. Through RNA sequencing, a total of 361 differentially expressed genes (DEGs) were identified. There was greater expression of genes, mainly tyrosine hydroxylase (TH), L-aromatic amino acid decarboxylase (DDC), and vesicular monoamine transporter (VMAT), involved in serotonin and dopamine biosynthesis and signaling in LWS than in HWS vehicle-injected chickens. In contrast, after insulin injection, these genes were more highly expressed in HWS than in LWS. We identified 90 single nucleotide polymorphisms (SNPs) existing only in the HWS and 121 SNPs specific to LWS and 5119 SNPs close to fixation (with absolute frequency difference ≥0.9). Four were located in genes encoding enzymes associated with serotonergic and dopaminergic pathways, such as DDC, TH, and solute carrier family 18, member 2 (VMAT). These data implicate differences in biogenic amines such as serotonin and dopamine in hypothalamic physiology between the chicken lines, and these differences might be associated with polymorphisms during long-term selection. Changes in serotonergic and dopaminergic signaling pathways in response to insulin injection suggest a role in whole-body energy homeostasis.

    2014-01-01

    Background Epidural lipomatosis (EL) is an increase of adipose tissue, normally occurring in the epidural space, sufficient to distort the thecal sac and compress neural elements. There is a lack of knowledge of risk factors, impact on patient’s symptoms, and its possible association with epidural steroid injections. Methods History, physical examination, patient chart, and MRI were analyzed from 856 outpatients referred for epidural steroid injections. Seventy patients with signs of EL on MRI comprised the study group. Thirty-four randomly selected patients comprised the control group. The severity of EL was determined by the MRI assessment. The impact of EL was determined by the patient’s history and physical examination. Logistic regression was used to correlate the probability of developing EL with BMI and epidural steroid injections. Results EL was centered at L5 and S1 segments. The average BMI for patients with EL was significantly greater than that of control group (36.0 ± 0.9 vs. 29.2 ± 0.9, p <0.01). The probability of developing EL with increasing BMI was linear up to the BMI of 35 after which it plateaued. Triglycerides were significantly higher for the EL group as compared to controls (250 ± 30 vs. 186 ± 21 mg/dL p < 0.01). The odds of having EL were 60% after two epidural steroid injections, 90% after three epidural steroid injections and approached 100% with further injections, independent of BMI. Other risk factors considered included alcohol abuse, use of protease inhibitors, levels of stress, hypothyroidism and genetic predisposition. However there were insufficient quantities to determine statistical significance with a degree of confidence. The impact of EL on patient’s symptoms correlated with EL severity with Spearman correlation coefficient of 0.73 at p < 0.01 significance level. Conclusions The BMI and triglycerides levels were found to be significantly elevated for the EL group, pointing to an increased

    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

    2011-01-01

    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.

    Osteoarthritis of the trapeziometacarpal joint is a common pathology. Numerous surgical procedures exist without any of one of them showing an obvious superiority. In our practice, when the trapezium is not big enough to allow use of a Roseland total joint arthroplasty, we used a combination of trapeziectomy and Dacron anchovy interposition. This simple and fast technique gives results similar to others in terms of pain, joint motion and strength. It appeared to be a safe technique until 2000, where an abnormal complication appeared: five implants (11% of the 46 used between 2000 and 2002) displayed a foreign body reaction both clinical and radiological, and three patients underwent revision surgery for ablation of the implant. Histological analysis confirmed this adverse reaction in all of the cases. In view of the delay between surgery and reaction we expect new cases to appear, thereby increasing the current rate. In view of the lack of any other explanation for these findings, the authors have stopped using the Dacron implant, and have instead reverted to a classical tendon interposition.

    Using a tissue cage infection rat model, we test the anti-biofilm effect of clarithromycin on the efficacy of daptomycin and a daptomycin + rifampicin combination against methicillin-susceptible (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA). In vitro: kill curves, daptomycin exposure studies and clarithromycin activity against biofilm were studied. In vivo: the efficacies of clarithromycin, daptomycin or daptomycin + clarithromycin, daptomycin + rifampicin and daptomycin + rifampicin + clarithromycin combinations were evaluated. In vitro: the addition of clarithromycin to daptomycin improved its activity only against one MRSA strain. Changes in daptomycin MIC values appeared more quickly in MSSA than in MRSA strain, and this was not modified by clarithromycin. Clarithromycin prevented biofilm formation but did not eradicate it. In vivo: the daptomycin + rifampicin combination was the most effective treatment and was not improved by the addition of clarithromycin. Daptomycin and daptomycin + clarithromycin had similar effectiveness; the combination protected against the appearance of daptomycin resistance only in one MRSA strain. Using a staphylococcal foreign-body infection model, we observed a slight effect with the addition of clarithromycin to daptomycin, which resulted in protection against the appearance of daptomycin-resistant strains. However, efficacy was not improved. Overall, our findings do not support a relevant clinical role for macrolides in treating device-related staphylococcal infections based on their anti-biofilm effect.

  11. A comparative clinical study of Solcoseryl Eye-Gel and Cysteine Eye-Gel 2.4% in the treatment of foreign-body injuries of the cornea.

    Solcoseryl, a protein-free haemodialysate, promotes tissue regeneration and improves utilization of oxygen in the cell. In a randomized, double-blind, clinical study, Solcoseryl Eye-Gel was compared with Cysteine Eye-Gel in the treatment of foreign-body injuries of the cornea in a total of 99 eyes. In order to facilitate objective evaluation of the effects of the treatment, the area of the lesion before the start of treatment and on the following day was determined by means of slit-lamp photographs. Healing of the lesion and relative reduction of the area of the wound were observed much more frequently in the group treated with Solcoseryl Eye-Gel than in the reference group. Maculae corneae after the end of the treatment were significantly less frequent under Solcoseryl Eye-Gel than under Cysteine Eye-Gel. Teh tolerability of the test preparation was good; an itching sensation was reported in only 2 cases. Under Cysteine Eye-Gel, on the other hand, a burning sensation was reported by a number of patients and very fine deposits in the epithelium were also observed in a few cases. Thus complete closure of the epithelium over the lesion after 1 day was observed much more frequently in the group of patients treated with Solcoseryl Eye-Gel than in the reference group (63 vs. 53%).

    For safe electrical stimulation with body-implanted devices, the degradation of stimulus electrodes must be considered because it causes the unexpected electrolysis of water and the destruction of tissues. To monitor the charge injection property (CIP) of stimulus electrodes while these devices are implanted, we have proposed a charge injection monitoring system (CIMS). CIMS can safely read out voltages produced by a biphasic current pulse to a stimulus electrode and CIP is calculated from waveforms of the acquired voltages. In this paper, we describe a wide-range and low-power analog front-end (AFE) for CIMS that has variable gain-frequency characteristics and low-power analog-to-digital (A/D) conversion to adjust to the degradation of stimulus electrodes. The designed AFE was fabricated with 0.18 µm CMOS technology and achieved a valuable gain of 20–60 dB, an upper cutoff frequency of 0.2–10 kHz, and low-power interleaving A/D conversion. In addition, we successfully measured the CIP of stimulus electrodes for body-implanted devices using CIMS.

    Chickens from lines selected for low (LWS) or high (HWS) body weight differ by 10-fold in body weight at 56 days old with differences in food intake, glucose regulation, and body composition. To evaluate if there are differences in appetite-regulatory factor and glucose transporter (GLUT) mRNA that are accentuated by hypoglycemia, blood glucose was measured, and hypothalamus, liver, pectoralis major, and abdominal fat collected at 90 days of age from female HWS and LWS chickens, and reciprocal crosses, HL and LH, at 60 min after intraperitoneal injection of insulin. Neuropeptide Y (NPY) and receptor (NPYR) subtypes 1 and 5 mRNA were greater in LWS compared with HWS hypothalamus (P < 0.05), but greater in HWS than LWS in fat (P < 0.05). Expression of NPYR2 was greater in LWS than HWS in pectoralis major (P < 0.05). There was greater expression in HWS than LWS for GLUT1 in hypothalamus and liver (P < 0.05), GLUT2 in fat and liver (P < 0.05), and GLUT9 in liver (P < 0.05). Insulin was associated with reduced blood glucose in all populations (P < 0.05) and reduced mRNA of insulin receptor (IR) and GLUT 2 and 3 in liver (P < 0.05). There was heterosis for mRNA, most notably NPYR1 (-78%) and NPYR5 (-81%) in fat and GLUT2 (-70%) in liver. Results suggest that NPY and GLUTs are associated with differences in energy homeostasis in LWS and HWS. Reduced GLUT and IR mRNA after insulin injection suggest a compensatory mechanism to prevent further hypoglycemia.

    The compound S38151 is a nanomolar antagonist that acts at the melanin-concentrating hormone receptor 1 (MCH1). S38151 is more stable than its purely peptide counterpart, essentially because of the blockade of its N-terminus. Therefore, its action on various models of obesity was studied. Acute intra-cerebroventricular (i.c.v.) administration of S38151 in wild-type rats counteracted the effect of the stable precursor of melanin-concentrating hormone (MCH), NEI-MCH, in a dose-dependent manner (from 0.5 to 50 nmol/kg). In genetically obese Zucker fa/fa rats, daily i.c.v. administration of S38151 induced dose-dependent (5, 10, and 20 nmol/kg) inhibition of food intake, water intake, and body weight gain, as well as increased motility (maximal effect observed at 20 nmol/kg). In Zucker fa/fa rats, intraperitoneal injection of S38151 (30 mg/kg) induced complete inhibition of food consumption within 1 h. Daily intraperitoneal injection of S38151 (10 and 30 mg/kg) into genetically obese ob/ob mice or diet-induced obese mice is able to limit body weight gain. Furthermore, S38151 administration (10 and 30 mg/kg) does not affect food intake, water intake, or body weight gain in MCHR1-deleted mice, demonstrating that its effects are linked to its interaction with MCH1. These results validate MCH1 as a target of interest in obesity. S38151 cannot progress to the clinical phase because it is still too poorly stable in vivo. PMID:23267345

    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.

    In addition to macrophages, multinucleated giant cells (MNGCs) are involved in the tissue reaction to a variety of biomaterials. Especially in the case of bone substitute materials it has been assumed that the MNGCs are osteoclasts, based on the chemical and physical similarity of many materials to the calcified matrix and the bony environment in which they are used. However, many studies indicate that these cells belong to the cell line of the foreign body giant cells (FBGCs), which are of "inflammatory origin", although they have been shown to possess both a pro- and also anti-inflammatory phenotype. Moreover, no information is available about their role in the tissue reaction to bone substitute materials. The present study was conducted to analyze the origin of MNGCs in the implant beds of a synthetic and a xenogeneic bone substitute and focused on the application of immunohistochemical methods. Two antibodies against integrin molecules specific for osteoclasts (β-3 integrin) or FBGCs (β-2 integrin) were used to distinguish both giant cell types. The results of the present study indicate that the MNGCs induced by both kinds of bone substitutes are FBGCs, as they express only β-2 integrin in contrast to the osteoclasts outside of the immediate implantation areas, which only demonstrate β-3 integrin expression. These data give new insight into the tissue reaction to both xenogeneic and synthetic bone substitutes. Based on this new knowledge further research concerning the proteomic profile of the FBGCs especially based on the different physicochemical properties of bone substitutes is necessary. This may show that specific characteristics of bone substitutes may exhibit a substantial influence on the regeneration process via the expression of anti-inflammatory molecules by FBGCs. Based on this information it may be possible to formulate and choose bone substitutes that can guide the process of bone tissue regeneration on the molecular level. © 2017 Wiley

    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 Cu(2+) 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.

    A comparative study was carried out with thirteen pigs, aged 1 to 3 days, to follow up the resorption and distribution of the Bulgarian iron-dextran preparations Ferdex-100, Dextrofer-75, A-100, and Miofer-100 in the body. Histochemically, an activation of the reticulo-endothelial system was established. Most macrophages that had phagocytised iron were established in the regional lymph nodes, followed by the liver, kidneys, marrow, while in the spleen their count was negligible. Using the histochemical reaction for the demonstration of iron in the viscera it was established that the A-100 preparation was best utilized by the organism. It was concluded that by the amounts of iron found in some organs it even exceeded Miofer-100.

    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.

    High-pressure paint injection injuries are relatively rare industrial accidents and almost exclusively occur on the non-dominant hand. A rarely documented complication of these injuries is the formation of a foreign body granuloma. We report a case of a 33-year-old man presenting with extensive facial scarring and progressive right paranasal swelling 7 years after a high-pressure paint injury. After imaging investigations, an excision of the mass and revision of scarring was performed. Access to the mass was gained indirectly through existing scarring over the nose to ensure an aesthetic result. Histological analysis revealed a florid granulomatous foreign body reaction to retained paint. To the best of our knowledge, this is the first reported case of a facial high-pressure paint injury with consequent formation of a foreign body granuloma.

    Background Detection of foreign bodies (FBs) is challenging. Selection of a fast and affordable imaging modality to locate the FB with minimal patient radiation dose is imperative. Objectives This study sought to compare four commonly used imaging modalities namely cone beam computed tomography (CBCT), magnetic resonance imaging (MRI), computed tomography (CT), and ultrasound (US) for detection of FBs in the head and neck region. Materials and Methods In this in vitro study, iron, glass, stone, wood, asphalt, and tooth samples measuring 0.1 × 0.5 × 0.5 cm were placed in the tongue muscle, soft tissue-bone interface and nasal cavity in a fresh sheep’s head and subjected to MRI, US, CT and CBCT. A total of 20 images were captured by each imaging system from the six materials in the afore-mentioned locations. The images were observed by an expert oral and maxillofacial radiologist and a general radiologist. To assess reliability, 20 images were randomly observed by the observers in two separate sessions. The images were classified into three groups of good visibility, bad visibility and invisible. The data were analyzed using SPSS version 18, Wilcoxon Signed Rank, Pearson chi square, and Fisher’s exact tests. Results All FBs in the tongue and at the soft tissue-bone interface had good visibility on US (P = 1.00). Also, CBCT and CT had significantly different performance regarding FB detection (P < 0.001). All wooden samples in the nasal cavity were invisible on CT scans; while, only 20% of them were invisible on CBCT scans. MRI showed significant differences for detection of FBs in the three locations (P < 0.001). MRI could not locate iron samples due to severe artifacts and only showed their presence (bad visibility) but other FBs except for wood and tooth in the nasal cavity (100% invisible) had good visibility on MRI. Conclusions Ultrasound is recommended as the first choice when FB is located within the superficial soft tissues with no bone around it. In

    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.

    Upper back pains lasting ten years were promptly improved in a 63 year old woman following the rejection of a forgotten foreign glass body, through a scar located over the left scapula, and treated by acupuncture. The patient insisted on having this treatment after unsuccessful prolonged and multi-disciplinary formal medical interventions culminating in preparations for exploratory surgery. The acupuncture directed to the scar induced an inflammatory reaction characterized by a sterile granulomatous reaction which surrounded a large piece of glass, apparently implanted in the soft tissue of the suprascapular area during a severe road accident which occurred ten years previously. The surgical intervention was avoided.

    Bystander effect induction by fathead minnows injected with environmentally relevant doses of (226)Ra was investigated. Twenty four h and 6 months after injection with a single dose of 21, 210 or 2100 μBq, fin tissue samples emitted a pro-apoptotic signal, which reduced the clonogenic survival of an apoptosis sensitive reporter cell line. Twenty four h and 10 weeks after injection explants from non-injected bystander fish, swum with the injected fish, also emitted a pro-apoptotic signal. However 6 months after injection the bystander fish to 21 and 210 μBq injected fish emitted an anti-apoptotic signal. This demonstrates that extremely low dose irradiation can have effects outside of the irradiated fish. This has implications for population and ecosystem responses to contamination.

    2017-01-01

    Background: Currently, there is no agreement on the optimal urinary derived human chorionic gonadotropin (u-hCG) dose requirement for initiating final oocyte maturation prior to oocyte collection in in vitro fertilization (IVF), but doses that range from 2500- 15000 IU have been used. We intended to determine whether low dose u-hCG was effective for oocyte maturation in IVF/intracytoplasmic sperm injection (ICSI) cycles independent of body mass index (BMI). Materials and Methods: We retrospectively evaluated a cohort of 295 women who underwent their first IVF/ICSI cycles between January 2003 and December 2010 at the Division of Reproductive Endocrinology and Infertility, Wayne State University, Detroit, MI, USA. Treatment cycles were divided into 3 groups based on BMI (kg/ m2): <25 (n=136), 25- <30 (n=84), and ≥30 (n=75) women. Patients received 5000, 10000 or 15000 IU u-hCG for final maturation prior to oocyte collection. The primary outcome was clinical pregnancy rates (CPRs) and secondary outcome was live birth rates (LBRs). Results: Only maternal age negatively impacted (P<0.001) CPR [odds ratio (OR=0.85, confidence interval (CI: 0.79-0.91)] and LBR (OR=0.84, CI: 0.78-0.90). Conclusion: Administration of lower dose u-hCG was effective for oocyte maturation in IVF and did not affect the CPRs and LBRs irrespective of BMI. Women’s BMI need not be taken into consideration in choosing the appropriate dose of u-hCG for final oocyte maturation prior to oocyte collection in IVF. Only maternal age at the time of IVF negatively influenced CPRs and LBRs in this study. PMID:28367299

    INTRODUCTION Lower urinary tract foreign body insertions have a low incidence. The motives for insertion of a variety of objects are difficult to comprehend. This case warrants discussion given the great management challenge faced by the oddity and infrequency with which a fork is encountered in the penile urethra. PRESENTATION OF CASE A 70-year-old man presents to the Emergency Department with a bleeding urethral meatus following self-insertion of a fork into the urethra to achieve sexual gratification. Multiple retrieval methods were contemplated with success achieved via forceps traction and copious lubrication. DISCUSSION The presentation of urethral foreign bodies can vary widely, as can the type of object inserted. The most prevalent motivation for self-insertion of urethral foreign bodies is autoerotism. Motivations ought to be explored in light of possible underlying psychological or psychiatric conditions. The most appropriate surgical extraction technique can be guided by physical examination and imaging. Endoscopic removal is often successful, depending on the object's physical attributes and morphology. It is important to arrange appropriate follow-up, as late complications can occur such as urethral strictures. CONCLUSION Psychological and surgical arms encompass the management plan. Foreign body retrieval is determined by its physical attributes and morphology with the aim to minimise urothelial trauma and preserve erectile function. Essentially, endourological extraction serves the primary means of retrieval. Cystourethoscopy is important to diagnose urothelial injuries and to ensure complete removal of foreign bodies following extraction. PMID:24055017

    This patent describes a cam for controlling the injection rate of fuel in a fuel injection system of an engine. The fuel injection system including a cyclically operating unit injector having a body, an injector plunger mounted for reciprocating movement in the injector body between an advanced position and a retracted portion to pump into the engine during each cycle a variable quantity of fuel up to a maximum quantity under rated engine conditions, and a drive train for converting rotational movement of the cam into reciprocating movement of the pumping plunger depending on the profile of the cam. The cam profile comprises at least a plunger retraction segment and a plunger advancement segment for controlling the velocity if injector plunger retraction and advancement, respectively, the plunger advancement segment including a pre-injection subsequent shaped to cause an initial quantity of fuel to be injected into the engine during each cycle at rated engine conditions while the pre-injection subsegment is in contact with the drive train, and an injection subsegment following the pre-injection subsegment.

  4. Delayed-onset ureteral obstruction after endoscopic dextranomer/hyaluronic acid copolymer (Deflux) injection for treatment of vesicoureteral reflux in children: a case series.

    2013-03-01

    We report 4 patients with upper urinary tract (UUT) obstruction requiring ureteric reimplantation at 1, 7, 28, and 63 months after dextranomer/hyaluronic acid copolymer (Dx/HA) injection for vesicoureteric reflux. Histopathologic evaluation of ureteric segments revealed extensive foreign body formation in all cases. We conclude that UUT obstruction is a rare but serious complication after Dx/HA injection that can occur even years after surgery. The incidence of delayed-onset UUT obstruction may be higher than previously noted. Long-term follow-up and a critical reappraisal of the method are needed to assess the late sequelae of Dx/HA injection therapy for vesicoureteric reflux.

    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).

    We constructed A-type inclusion body (ATI) hybrid promoters, that is, late ATI promoters followed by tandemly repeated early regions of the promoter for the 7.5-kDa protein (the 7.5-kDa promoter). The repetition of the whole early promoter sequence of the 7.5-kDa gene, including the upstream consensus sequence and initiation region, efficiently increased the early expression of the bacterial chloramphenicol acetyltransferase gene in recombinant vaccinia virus. Recombinant vaccinia virus could express influenza virus hemagglutinin via the hybrid promoter more efficiently, induced higher levels of neutralizing antibody and cytotoxic T lymphocytes, and consequently protected mice more efficiently against challenge with influenza virus than did recombinant vaccinia virus containing the widely used 7.5-kDa promoter.

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

    PubMed

    Friedmann, Daniel P; Kurian, Anil; Fitzpatrick, Richard E

    2016-06-01

    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.

  18. The mechanism of body temperature changes induced by intraventricular injections of adrenaline, noradrenaline and 5-hydroxytryptamine in the ox (bos taurus)

    1. Adrenaline, noradrenaline and 5-hydroxytryptamine (5-HT) were injected into the lateral ventricle of the ox. The effect of these drugs was measured on the respiratory rate, tidal volume, heat production, skin temperature of the ear, evaporative loss from the skin and the rectal temperature at 20 and 10° C ambient temperature. 2. Neither adrenaline (3 mg) nor noradrenaline (3 mg) had any effect on the temperature regulating mechanisms of the ox, except to produce vasoconstriction if vasodilatation was already present due to high ambient temperature or previous injection of 5-HT. 3. Injection of 5-HT (5 mg) caused a rise in respiratory rate, a fall in tidal volume and heat production, elevation of ear skin temperature and skin evaporative loss and a decrease in rectal temperature. Sedation of the animals occurred. 4. In its reaction to these monoamines the ox is similar to the goat, sheep and rabbit, but is unlike the cat and dog. 5. It was concluded that neither adrenaline nor noradrenaline has a role in the central control of temperature regulation in the ox, but that 5-HT may be involved in the control of heat dissipation mechanisms.

    Background The clinical implications of lower body weight in drug using populations are uncertain given that lower mean weights may still fall within the healthy range. Objectives To determine the effect of type, mode and frequency of drug use on underlying body composition after accounting for differences in body shape and size. Methods We conducted a cross-sectional analysis of 511 participants from the Tufts Nutrition Collaborative (TNC) Study. Data included measures of body composition, a 24-hour dietary recall, and a detailed health history and lifestyle questionnaire. Multivariate regression analysis was used to determine the independent effect of drug use on percent body fat (BF) after adjusting for BMI and waist circumference. Results Heavy injection drug users (IDUs) had a 2.6% lower percent BF than non-users after adjusting for BMI, waist circumference, and other confounders. (p=0.0006). Differences in percent BF were predominantly due to higher lean mass, rather than lower fat mass. Cocaine and heroin had similar effects on body composition. Conclusions In the U.S., where the general population is prone to over-nutrition, the average percent BF for heavy injectors does not fall into a range low enough to suggest harmful effects. However, in populations with substantial levels of under-nutrition, small differences in percent BF among drug users will have a greater impact on health status. Scientific Significance Differences in BMI, weight and body composition are not always straightforward. Accounting for underlying nutritional status and relative differences in fat and FFM is critical when interpreting results. PMID:20141402

  20. Development and functional evaluation of biomimetic silicone surfaces with hierarchical micro/nano-topographical features demonstrates favourable in vitro foreign body response of breast-derived fibroblasts.

    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.
