Ultrasound-assisted foreign body extraction (U-SAFE): Review of technique and technical pearls.

Soft tissue foreign bodies are a common presentation to emergency departments and primary care. They have variable presentations and associated morbidity depending on their acuity, location, functional impairment and neurovascular involvement. Traditional removal has utilised blind technique or surgical exploration. Their removal can be difficult secondary to induration, inflammation, granulation and scar tissue. Ultrasonography has emerged as a minimally invasive and inexpensive method of examination and retrieval. This article entails ultrasound-guided foreign body extraction with associated pearls of experience. From March 2017 to August 2020, a fellowship trained interventional radiologist and a fellowship trained musculoskeletal radiologist performed 52 foreign body extractions under ultrasound guidance at a single institution. 52 foreign body extractions occurred over 3-year time period with a 95% success rate. The most common location of foreign body was the finger (62%) and feet/toes (17%). Foreign bodies identified include wood (31%), plant-based material (29%), metal (17%), glass (17%) and synthetic material (6%). Two unsuccessful cases were secondary to delayed presentation with significant foreign body reaction and the 2nd due to patient psychiatric issues. There were no identified complications. Ultrasonography-guided foreign body extraction is a minimally invasive, efficient and targeted technique for foreign body removal.

Foreign Body Aspiration in Egyptian Children Clinical, Radiological and Bronchoscopic Findings.

PurposeForeign body aspiration (FBA) is a frequent cause of childhood morbidity and mortality. Diagnosis of FBA is challenging in the absence of a witnessed aspiration event. The aim of this study was to determine the accuracy of presenting symptoms as well as physical and radiologic findings as predictors of FBA in children. Thus, indications for bronchoscopy could be determined in such cases.MethodsThis retrospective cohort study was conducted in the ENT department, Kafr-elsheikh University Hospital. The medical records of patients younger than 16 years old who underwent rigid bronchoscopy for suspected FBA were included. Data including age, gender, symptoms, physical examination findings, radiological features, nature and location of foreign body, and outcome of the bronchoscopy were collected.ResultsThis study included 130 patients, 105 (80.8%) patients were positive for the presence of a foreign body in their airways. Foreign bodies were most frequently (43.8%) lodged in the right main bronchus, and nuts (66.7%), were the most commonly retrieved. Multivariate regression analysis identified the presence of suggestive signs or symptoms as independent predictors of FBA on rigid bronchoscopy.ConclusionObjective finding of clinical signs eg unilateral wheezes on chest examination in the presence of symptoms such as a sudden cough, dyspnea, and hoarseness could predict FBA and help physicians in deciding bronchoscopy.

A first-aid fast track channel for rescuing critically ill children with airway foreign bodies: our clinical experience

ObjectiveTo explore the role of a first-aid fast track channel in rescuing children with airway foreign bodies and to analyse and summarize the experience and lessons of the first-aid fast track channel in rescuing airway foreign bodies from patients in critical condition.MethodsWe retrospectively reviewed the medical records of children with airway foreign bodies rescued by first-aid fast track channels admitted to our hospital from January 2017 to December 2020. The corresponding clinical features, treatments, and prognoses were summarized.ResultsClinical data from 21 cases of first-aid fast track channel patients were retrospectively collected, including 12 males and 9 females aged 9–18 months. Cough was the most frequently exhibited symptom (100.0%), followed by III inspiratory dyspnoea (71.4%). Regarding the location of foreign bodies, 5 cases (23.8%) had glottic foreign bodies, 10 cases (47.6%) had tracheal foreign bodies, and 6 cases (28.6%) had bilateral bronchial foreign bodies. The most common type of FB was organic. FB removal was performed by rigid bronchoscopy in every case, and there were no complications of laryngeal oedema, subcutaneous emphysema, or pneumothorax. No tracheotomy was performed in any of the children.ConclusionThe first-aid fast track channel for airway foreign bodies saves a valuable time for rescue, highlights the purpose of rescue, improves the success rate of rescue and the quality of life of children, and is of great value for the treatment of critical tracheal foreign bodies. It is necessary to regularly summarize the experience of the first-aid fast track channel of airway foreign bodies and further optimize the setting of the first-aid fast track channel.

Optimized Fuzzy C-Means Algorithm-Based Coronal Magnetic Resonance Imaging Scanning in Tracheal Foreign Bodies of Children.

In order to provide theoretical support for clinical diagnosis, the diagnostic value of the optimized fuzzy C-means (FCM) algorithm combined with coronal magnetic resonance imaging (MRI) scan was investigated in the diagnosis of tracheal foreign bodies in children. The anisotropic filtering was applied to optimize the traditional FCM algorithm, so as to construct a new MRI image segmentation algorithm, namely, AFFCM algorithm. Then, the traditional FCM algorithm, the FCM algorithm based on the kernel function (KFCM), and the FCM algorithm based on the spatial neighborhood information (RFCM) were introduced for comparison with the AFFCM. 28 children diagnosed with foreign bodies in the trachea were selected for MRI diagnosis, and AFFCM was used for segmentation. The partition coefficient, segmentation entropy, and the correlation degree between classes after fuzzy division of the four algorithms were recorded, and the location and distribution of foreign bodies in the trachea and the types of foreign bodies were also collected. Besides, the MRI scanning and chest X-rays of the children with foreign bodies in the trachea should also be recorded in terms of the positive rate, diagnosis rate, and indirect signs. The class division coefficient and interclass correlation degree after fuzzy division of AFFCM were markedly greater than those of FCM, KFCM, and RFCM (P < 0.05), while the segmentation entropy of AFFCM was less sharp than the entropies of FCM, KFCM, and RFCM (P < 0.05). Among the 28 children, there were 5 cases with foreign bodies in the trachea (17.86%), 10 cases in the left bronchus (35.71%), and 13 cases in the right bronchus (46.43%). Among the foreign body types, there were 10 cases of melon seeds (35.71%), 6 cases of peanuts (21.43%), and 5 cases of beans (17.86%). The positive rate (89.29%) and diagnosis rate (96.43%) of MRI for bronchial foreign bodies increased obviously in contrast to the rates of X-ray chest radiographs (57.14% and 67.86%) (P < 0.05). Therefore, it was indicated that AFFCM showed higher partition coefficient value, lower segmentation entropy, larger similarity among classes, and better image segmentation effect. Furthermore, AFFCM-based coronal MRI scan had a higher positive rate and diagnosis rate for children's tracheal foreign bodies, and the main signs were emphysema and atelectasis.

FOREIGN BODY IN THE DIGESTIVE TRACT (ESOPHAGUS) CASE STUDY

The majority of foreign body ingestions occur in children between the ages of six months and three years. Most cases are brought to medical attention by a child's caregivers following a witnessed or reported ingestion. Many of the children are asymptomatic or have transient symptoms at the time of the ingestion. Clinical management focuses on identifying and treating the cases at risk for complications, which depend on the location and type of foreign body. A battery lodged in the esophagus should be removed urgently. There was not recommended to take anything orally when swallowing a battery according to these guidelines until the body has been radiographically determined and removed endoscopically. Recent studies using natural and artificial models of batteries in the esophagus of animals have shown that early and repeated administration of honey or sucralfate before removal may reduce the degree of esophageal burns.

BACKGROUND Foreign body aspiration (FBA) in children is one of the major causes of death in developing countries, the diagnosis of which can be missed due to varied presentation. It is one of the causes of choking among children which, if not recognized early may lead to fatal consequences. Early recognition and prompt intervention may reduce the mortality and morbidity. In this study, we wanted to assess the clinical profile of children with foreign body aspiration/ingestion, determine the nature and location of foreign body and also determine the outcome among children with foreign body aspiration at a tertiary care centre. METHODS This cross-sectional study was taken up to analyse the clinical profile, to study the types, location and the outcome of children with foreign body aspiration. All children in the age group of 2 months to 12 years admitted to Niloufer hospital, Hyderabad from January 2018 to December 2019 with either history of FBA or clinical features suggestive of FBA even in the absence of history were included in the study. Age, sex, clinical features (C/F), duration of illness were noted. A chest X-ray was done in all cases, whereas a computed tomography (CT) scan was done in children where clinical features &amp; chest X-rays were inconclusive. All children fulfilling the inclusion criteria were subjected to bronchoscopy under general anaesthesia by ENT surgeons. The findings like type and location of the foreign bodies were noted. Statistical analysis was done by statistical package for social sciences (SPSS) software version 10.0. RESULTS Of 108 children studied, 60 % of cases were males and 40 % were females. 55 % of cases were below the age of 3 years. Common symptoms were rapid breathing (68 %) and cough (38.8 %). Nuts &amp; seeds were the common foreign bodies seen in 47.30 %, out of which groundnuts were the most common. Organic foreign bodies accounted for 58.11 % while inorganic was 41.89 %. The common site of lodgement of foreign body was right main bronchus (35.59 %), followed by left main bronchus (27.11 %) and sub-glottis (8.47 %). CONCLUSIONS Foreign body aspiration is difficult to diagnose in children and a delay in diagnosis can lead to mortality and morbidity. Early intervention by bronchoscopy goes a long way in improving survival. Clinical suspicion is the key to the diagnosis. KEYWORDS Foreign Body, Bronchoscopy, Children

Sonographic Evaluation of a Perpetual Penetrating Retained Wood Splinter, Ulnar Artery Occlusion, and Soft Tissue Swelling in the Left Arm

Penetrating foreign bodies are frequently encountered, most commonly wood, glass, or metal slivers. Retained foreign bodies are often overlooked on initial examination and only 15% of wooden foreign bodies are detected by radiographic visualization such as radiography (X-ray), computerized tomography (CT), and magnetic resonance imaging (MRI). Soft tissue infection is the most common complication of a penetrating foreign body. This case report describes a 63-year-old man who was caught under a falling tree limb. His left forearm was speared by a large branch causing an open wound. Ten years later, the patient presented to the emergency department with pain, edema, and erythema. A left arm venous duplex was performed using dynamic B-mode imaging with pulsed Doppler to evaluate the venous system for thrombosis and a palpable mass. Sonography revealed a “perpetual” retained linear foreign body encased in a fluid collection and a distal ulnar artery occlusion with reconstitution of flow at the level of the wrist. Surgical correlation confirmed the presence, size, and location of the foreign body and associated fluid and debris. The foreign body, a wood splinter, was surgically removed without complications.

Anterior segment optical coherence tomography aided delineation of metallic intraocular foreign body

Penetrating ocular injury is an important cause of loss of vision and may be associated with the presence of intraocular foreign body (IOFB). Missed IOFB may present with non-specific clinical features which may delay accurate diagnosis and proper management. We are presenting a case of unusual retained intraocular foreign body in a 38-year-old woman which emphasizes the need of careful review of patient's traumatic history and need of investigation like anterior segment optical coherence tomography (ASOCT) in diagnosis, localization of foreign body and follow-up after foreign body removal.

Factors affecting successful esophageal foreign body removal using a Foley catheter in pediatric patients.

ObjectiveThis study aimed to determine the factors that affect successful esophageal foreign body (FB) removal using a Foley catheter and to identify methods to increase the success rate.MethodsIn this retrospective, cross-sectional study, we included pediatric patients who presented with esophageal FB impaction that was removed using a Foley catheter in the emergency departments of tertiary care and academic hospitals. We analyzed the effect of the patients’ age, sex, and symptoms; FB type, size, and location; Foley catheter size; complications during FB removal; duration between FB ingestion and removal; operator’s years of training; sedation; success rate of FB removal; endoscopy; and patient’s posture during FB removal on the success of Foley catheter-based FB removal.ResultsOf the 43 patients we enrolled, Foley catheter-based FB removal was successful in 81.4% (35/43) but failed in 18.6% (8/43) of patients; no FB-removal-related complications were reported. There was no significant association between the success rate of Foley catheter-based FB removal and any study variable. A higher number of years in training tended to increase the success rate of Foley catheter-based FB removal, although statistical significance was not achieved.ConclusionChildren’s esophageal FB removal is a practical challenge in the emergency rooms, and using a Foley catheter is associated with a high success rate of the removal and low occurrence of complications. In this study, no single variable was found correlated with the success rate of Foley catheter-based esophageal FB removal in pediatric patients, which may indicate multiple variables interacting with one another to affect the success rate.

Clinical analysis of tracheobronchial foreign body aspiration in children: a focus on external and intrinsic factors

BackgroundTracheobronchial foreign body aspiration (TFBA) is a critical disease in children and is extremely dangerous, even life-threatening. The factors affecting the occurrence and prognosis of TFBA are complex. The purpose of this study is to examine the external and intrinsic factors affecting clinical features of TFBA in West China and propose potential effective intervention measures.MethodsWe retrospectively analyzed the clinical data of pediatric patients diagnosed with TFBA with foreign bodies (FBs) removed by rigid bronchoscopy under general anesthesia at the otolaryngology department from December 2017 to November 2018. The data included age, sex, clinical symptoms, type and location of FB, guardians, prehospital duration and residence of these pediatric patients.ResultsThe ratio of males (72) to females (53) was 1.4:1. Children aged from 1 to 3 years accounted for 76% (95/125) of patients. Cough, continuous fever and dyspnea were the primary symptoms. The right primary bronchus was the most common location of FB detection by rigid bronchoscopy (67 cases, 53.6%). Organic FBs were most common in our study. Guardians of patients significantly differed in the rural (parents 16, grandparents 31) and urban (parents 52, grandparents 26) groups (χ2 = 12.583, p = 0.000). More children in the rural group than in the urban group had a treatment delay longer than 72 h. More children in the group with no history of FB aspiration (12, 25%) than in the group with prior FB aspiration had a treatment delay longer than 72 h.ConclusionPediatric TFBA is a common emergency in otolaryngology. Age, sex, tracheobronchial anatomy and other physiological elements were defined as intrinsic factors, while guardians, residence, FB species and prehospital time were defined as external factors of TFBA. External and intrinsic factors both influence the occurrence and progression of TFBA. It is extremely important to take effective measures to control external factors, which can decrease morbidity and mortality.

The removal of foreign body ingestion in the upper gastrointestinal tract: a retrospective study of 1,182 adult cases.

BackgroundForeign body (FB) ingestion in the gastrointestinal tract is a common and urgent problem observed in children and adults. However, there may be difficulty locating FBs and complications associated with their removal. This study aimed to identify risk factors and complications correlated to the presence and removal of FBs.MethodsThis 5-year retrospective study enrolled 1,311 patients between June 2014 and April 2019. Demographic and endoscopic data were collected, containing age, gender, types and location of FBs, duration of FB ingestion, accessory devices, endoscopic methods, and complications. Logistic regression analysis was applied to evaluate the predictive risk factors.ResultsAmong 1,131 patients, FBs were found in 90.16% of cases. A major predictor for the presence of FB was a presentation of less than 24 hours (h). The types of FBs were jujube pits (36.72%) and fish bones (22.00%), and over 80% of the FBs were discovered in the esophagus. Complications were found in 239 cases (20.22%), of which hemorrhage (162/239, 67.78%) was the most frequent. Age ≥60, duration ≥24 h, and FBs ingested in the esophagus were considered as risk factors for developing complications.ConclusionsIn conclusion, the longer duration, age ≥60, and impaction in the esophagus were risk factors for developing complications following the ingestion of FBs. These factors should be considered when developing assessment and treatment plans in the management of FB ingestion.

Foreign Body Nose: An Unusual Presentation

Introduction This is a very interesting case of retained homicidal foreign body in the nose in contrast to most of the foreign bodies which are accidental. Case Report A 27 year old male presented to ENT emergency with alleged history of assault over face with sharp object following which patient developed nasal bleed. On examination vertical laceration of approximately 8 cm in length was present along left naso-orbital groove extending superiorly from medial canthus of left eye and inferiorly to nasal alar cartilage. On anterior rhinoscopy a metallic foreign body was seen in both nasal cavities, which appeared to be crossing from left to right side piercing the nasal septum. Foreign body was removed via open approach. Discussion Penetrating maxillofacial injury with foreign body impaction are less common. High index of suspicion is required in diagnosing these cases. Radiological intervention should be done to get idea of exact location and extent of foreign body. Lateral rhinotomy is a useful approach in removing these foreign bodies.

Comparison of Endoscopy Alone with Surgery Converted from Endoscopy for the Removal of Esophageal Foreign Bodies in Adults: A Retrospective Study from a Single Center

BackgroundThe impaction of an esophageal foreign body is an urgent situation requiring emergency intervention. This retrospective study from a single center in China aimed to compare endoscopy alone with surgery converted from endoscopy for the removal of esophageal foreign bodies in adults.Material/MethodsA total of 252 patients with esophageal foreign bodies were divided into 3 groups based on the treatment received: endoscopy, surgery converted from endoscopy, or surgery only. Patients’ clinical and demographic data were retrospectively reviewed and analyzed.ResultsThe diameter of the foreign bodies in patients treated by surgery converted from endoscopy was larger than that of those treated by simple endoscopy (5.2 cm vs 2.7 cm, P=0.0003). The cervical or upper thoracic esophagus was the most common site of foreign body impaction treated by surgery converted from endoscopy, while the foreign bodies removed by simple endoscopy were frequently lodged at the middle thoracic esophagus (P=0.021). Bone-related foreign bodies and dentures were most likely impacted in patients treated with surgery converted from endoscopy. The factors influencing the choice of treatment included foreign body maximal diameter and location.ConclusionsLarger foreign bodies that were found in the cervical or upper thoracic esophagus were associated with failed endoscopic removal and required surgical removal. Irregularly shaped or sharp foreign bodies, including dentures and fishbones, required surgical removal. These findings may guide future decisions of first-line approaches for the removal of esophageal foreign bodies.

Celiotomia e gastrotomia para remoção cirúrgica de corpos estranhos em axolote (Ambystoma mexicanum): relato de caso

The ingestion of foreign bodies in artificial aquariums is a frequent occurrence observed in the surgical clinic of amphibians raised as pets, which includes axolotls (Ambystoma mexicanum). The present report describes a case of ingestion of seven foreign bodies in a male axolotl, five months old, with a history of irregular and irreducible bulging of the ventral body surface, with firm consistency. In the anamnesis, it was reported that the animal inhabited an aquariums with gravel substrate. On physical examination, the axolotl showed good general condition and vital parameters within the normal range for the species. The swallowed materials were identified in the gastric region by means of total body radiographic examination, and their characteristics were consistent with the substrate used in the patient’s aquarium. As anesthetic protocol, immersion in Isofluorane and oxygen gas was prioritized, in order to reach the branchial and, occasionally, transdermal route. Surgical removal was performed through celiotomy and gastrotomy in an aquatic environment with controlled temperature, pH and bacterial collection, according to available literature and taking into account the nature, diameter and location of foreign bodies. After five and fifteen days of the procedure, the healing of the surgical wound was monitored, showing a good restoration of tissue continuity and a good general condition of the patient.

DIAGNOSTICS AND SURGICAL TREATMENT OF GUNSHOT WOUNDS OF THE UPPER AND LOWER LIMBS WITH THE PRESENCE OF FOREIGN BODIES

Summary. The aim. Comparison of clinical, clinical instrumental and morphological data to establish the most informative signs of extremity foreign bodies, the possibility of choosing surgical tactics and improving treatment results.&#x0D; Materials and methods. Removal of ferromagnetic metallic foreign bodies of various sizes was carried out under visual control using a magnetic search tool. Visual control of the removal of a foreign body allows you to assess the adequacy of its removal.&#x0D; Results and its discussion. Removal of a foreign body was carried out using general surgical instrumentation under tactile control using the surgeon's finger and a Billroth curved hemostatic clamp or a mosquito curved hemostatic clamp.&#x0D; Removal of foreign bodies of extremities under hardware control is possible both in continuous time (on line) and intermittent (step-by-step) mode - detection of foreign bodies, marking (leaving marks on the skin).&#x0D; Removal of a foreign body was also carried out under X-ray control. Most often, a step-by-step technique was used, in which the characteristics of a foreign body were first determined, then it was removed and, finally, a control X-ray study was performed with uncertainty about the completeness of removal.&#x0D; In cases where there were problems with the spatial perception of the location of foreign bodies, the removal of foreign bodies under visual, tactile and hardware control was difficult, we used a combination of these methods.&#x0D; Conclusions. As a result of using the proposed modern diagnostic technologies, the completeness of removal of extremities foreign bodies significantly increased from 6.2±0.1 to 1.4±0.1 (p&lt;0.005); the duration of their removal decreased from 30.4±1.8 to 11.2±1.3 minutes (p&lt;0.005); the number of surgical interventions decreased from 2.8±0.2 to 1.7±0.1 (p&lt;0.005); the expressiveness of the pain syndrome decreased from 7.3±0.2 to 5.2±0.4 points (p&lt;0.005); the duration of inpatient treatment decreased from 18.6±1.1 to 16.5±1.3 days.

Migratory foreign body of hypopharynx

A 22-year-old male, tailor by profession presented to Ear Nose Throat (ENT) emergency with accidental ingestion of needle while cleaning his teeth which was associated with difficulty in swallowing (more for solids than liquids) and irritation in throat. On clinical examination no foreign body was seen. Diagnosis of extraluminal migration can be done with the help of Computed tomograms (CT) scans which can provide exact location of foreign body before surgical exploration. C-arm can be utilized specially in metallic foreign bodies to localize during the surgery. In our case both CT and C-Arm were used and foreign body was removed by transcervical route without any complication. In case of absence of foreign body on intraluminal assessment, possibility of migration of foreign body should be completely ruled out and patient should be investigated accordingly.

Clinical and radiological characteristics of oro-antral communications/fistulae due to implant dentistry procedures: A cross-sectional retrospective study.

Assess the unique clinical and radiological sequelae following oro-antral communications/fistulae (OAC/OAF) due to implant dentistry vs other etiologies. A structured form served to collect data from medical records. All consecutive patients who underwent surgical closure of OACs/OAFs between 2003 and 2020, at a single center were included. Demographic, radiological, clinical, operative and postoperative characteristics were collected. The differences between groups (cases with implant dentistry etiology [IDE] vs cases with other etiologies) were assessed statistically. Data were gathered from 121 cases. The findings show that IDE cases were more likely to be of older age (OR = 1.07, CI [1.02, 1.13] P = .02); to have a foreign body in the maxillary sinus (OR = 21.04, CI [4.34, 114.92] P < .01); to have fluid passage (OR = 11.40, CI [1.87, 118.73] P = .02) and purulent discharge through the fistula (OR = 3.52, CI [0.86, 16.34] P = .09). Clinical and radiological sequelae due to OACs/OAFs secondary to implant dentistry procedures are more severe compared to other etiologies. The suggested pathogenesis is foreign body reaction. Early and accurate diagnosis of the foreign body location, followed by its early removal is recommended.

Retained Foreign Body Which Should be Suspected as a Cause of Retractable Chronic Hand Inflammation and Diagnostic Capacity of Ultrasonography

Background: Foreign bodies in the hand are common but easily and often missed in the initial evaluation of injury. Diagnosing retained foreign bodies is difficult due to radiolucent foreign bodies. Purpose of this study is to emphasize the need of consideration of foreign bodies in patients with chronic synovitis in hand. Methods: Twenty-five patients who had retained foreign body in soft tissue of hand with chronic inflammation symptoms were included. Ultrasonography was conducted in all of the patients. Patient age, sex, localization of foreign body, duration of symptom, history of injury, follow up period, complication, and biopsy results were recorded and reviewed. Also, patients' demographics and clinical results were retrospectively reviewed. Results: Nine of the 25 patients diagnosed with a foreign body in the hand did not remember the initial presentation of injury. The average symptom duration (from injury to hospitalization) was 10.5 months (range 1-96 months). The middle finger and the proximal interphalangeal joint were the most common site of a retained foreign body (10 patients). All patients were diagnosed via ultrasonography and underwent surgery. Biopsy results showed mainly chronic inflammation, fibrosis, granuloma, and foreign bodies. Conclusions: Patient with symptoms of cellulitis, osteomyelitis, and palpable mass in hand for over a month without a diagnosis should be suspected of retained FBs.

History Page: Leaders in MSK Radiology.

Born in 1869, Gaston Contremoulins began his career as a painter. Fascinated by photography and discovery of X-rays by Roentgen in 1895, our ingenious self taught engineer joined the laboratory of microphotography in the faculty of medicine in Paris. He published in 1896 studies in the use of X-rays associated with a compass for research and anatomical localization of foreign bodies in the skull. This work was awarded by the Montyon prize of the French Academy of Sciences in 1897. Appointed chief of radiological laboratories in Paris Hospital in 1898, despite the fact that he was not doctor, he developed his method named metro radiography for localization, then extraction of foreign bodies in all organs mainly during World War 1. He developed with surgeons osteosynthesis and prothesis for wounded soldiers. Early awareness of radiation hazards for physicians, hospital staff and also the neighborhood of the radiological installation, Contremoulins developed ways of protecting source and also promoted the shielding of walls and floors, despite the opposition of some of the radiologists. Retired from the Necker Hospital in 1934, he exercised his talents in the Saint-Germain-en-Laye Hospital for another 16 years. He ended his days in 1950 after he was diagnosed with inoperable cataracts.

Nasal foreign bodies identified by rhinoscopy in dogs: 42 cases.

To evaluate signalment, clinical presentation, location and type of nasal foreign bodies identified by rhinoscopy in dogs. We retrospectively reviewed medical records from dogs that presented for consultation between April 2012 and June 2019 and were diagnosed with nasal foreign body via rhinoscopy. Forty-two dogs met the study's inclusion criteria. Thirty (71.4%; 30/42) were purebreds. Males accounted for 59.5% (25/42) of cases. The median age was 4.0 years old and 76.2% (32/42) were dogs up to 7 years of age. Mean bodyweight was 21.8kg and dogs weighing more than 10kg were overrepresented (78.6%; 33/42). Sneezing occurred in 78.6% (33/42) of cases. Foreign body retrieval was achieved by rhinoscopy in all cases. The foreign body was extracted from the right nasal cavity in 52.4% (22/42) of cases and from the left one in 42.9% (18/42). Two dogs (4.8%; 2/42) presented with one foreign body in each nasal cavity. Most nasal cavity foreign bodies (90.5%; 38/42) were grass awns. Three (7.2%; 3/42) were mineral and one (1/42) was fabric. Follow-up was documented for 35 patients, of which 97.1% (34/35) experienced resolution of clinical signs. Seven cases (16.7%; 7/42) were lost to follow-up. Nasal foreign bodies were more common in dogs up to 7 years of age and heavier than 10kg. Sneezing was the primary clinical sign. The vast majority of foreign bodies were grass awns and rhinoscopy was an effective means of nasal cavity foreign body retrieval.
