Project description:BackgroundForeign body aspiration (FBA) in children has a high morbidity, and early diagnosis is the key for preventing acute and chronic respiratory complications. To diagnose FBA, commonly used imaging modalities have limited negative predictive value, and rigid bronchoscopy remains as the gold standard. We present a case where the diagnosis of FBA was made in a novel way with electrical impedance tomography (EIT). Case Presentation. A 19-month-old previously healthy boy was admitted with a clinical diagnosis of respiratory failure secondary to bronchiolitis. Chest X-ray showed bilateral lung hyperinflation. He enrolled in a research study which used EIT to measure the effects of high flow nasal cannula (HFNC) on minute ventilation in children with bronchiolitis. On initiation, the patient had near-normal right lung ventilation (98%) and near-absent left lung ventilation (2%). We discontinued the study and alerted the medical team that we suspected FBA. Further imaging (lateral decubitus films and lung ultrasounds) was also obtained, but was not diagnostic. Rigid bronchoscopy was performed and showed a peanut occluding the left mainstem bronchus (LMB). The peanut was removed followed by complete resolution of the patient's symptoms.ConclusionsWe believe this is the first reported case of FBA diagnosed via EIT. EIT has been shown to be a useful but underutilized technology for diagnosing respiratory disease. While FBA remains a relatively common cause of morbidity and mortality in children less than age four, early diagnosis remains difficult and requires vigilance. This case illustrates the challenges of relying on chest films and ultrasound to assist with diagnosis and suggests that EIT in combination with a thorough history and physical exam can be used to confirm the presence of FBA.

Project description:Esophageal foreign bodies (FBs) are common and can be the serious cause of morbidity and mortality in children. One-third of FBs, retained in the gastrointestinal tract, are found in the esophagus. Their management depends on the anatomical location, shape, size, and the duration of impaction. In children, unwitnessed esophageal FBs can present with respiratory symptoms such as stridor. Therefore, a high index of suspicion is generally required to avoid significant morbidity and mortality. We are reporting an unusual FB with unusual symptoms in a 2-year-old female child.

Project description:In medical literature there are several case reports of foreign bodies introduced into the urethra. Foreign bodies are usually inserted as result of erotic activities, psychiatric disorders and, rarely, in an attempt to evacuate the urine. Diagnosis is based on clinical examination and imaging tests. Endoscopic management is the treatment of choice but, in some cases, open surgery may be necessary. The therapeutic approach should be systematically complemented by a psychiatric assessment of the patient. We report the case a 64-year old man with a personal history of behavioral disorders who introduced an electric wire in his urethra. The patient underwent endoscopic extraction under regional anesthesia. The patient at the time of discharge was referred to a psychiatrist.

Project description:Introduction:Accidental foreign body aspiration can cause severe damage to the airway and threaten the patient's life. This situation requires multidisciplinary and systematic approach from the medical and surgical team, in order to achieve complete resolution maintaining airway permeability. Presentation of case:This is a 49 y/o man who presented with a severe asthma attack, in whom an unsuspected foreign body in the inferior airway was diagnosed, which was possibly the result of aspiration during the initial emergency care, causing worsening of the already critical condition. Discussion:We described the clinical course, radiologic and endoscopic findings, and outcome of the patient, highlighting the importance of considering the possibility of a foreign body in the airway, when there is no improvement in refractory status asthmaticus. This is particularly important in a university hospital. Moreover, the implementation of checklists when invasive procedures are performed can avoid loss of material, preventing iatrogenic aspiration events. Conclusion:Foreign body aspirations may remain undetected due to lack of suspicion, especially in adults, in whom they can cause chronic symptoms, or worsen chronic respiratory conditions turning them into more complex diseases. This cause must be considered in the differential diagnosis of refractory status asthmaticus.

Project description:Wooden foreign bodies penetrating through the orbit into paranasal sinuses are rare. We report a case of a young male who complained of double vision, pain and redness after a fall from a tree. There was no external wound over periocular skin. The clinical and radiological examination was suggestive of an inferior orbito-sinal wooden foreign body with floor fracture, which was managed by surgical removal of the foreign body and orbital floor fracture repair using a silicon sheet in a single sitting.

Project description:Abdominal pain is a common presentation in emergency medicine. We describe the case of a 54-year-old female who presented to the emergency department due to worsening abdominal pain. She had a history of right upper quadrant (RUQ) abdominal pain that had been ongoing for several months. The pain had been thought by the primary care team to be related to gastritis and she had been prescribed a proton pump inhibitor (PPI). Her abdominal pain increased in the three days prior to her presentation to the emergency department (ED). The computed tomography (CT) scan of the abdomen showed a foreign body (FB) in the liver which was successfully removed surgically. Pathology results showed that the FB was consistent with a small bone fragment. Ingestions of FB are common but seldom result in complications. When complications do arise, perforation of a hollow viscous is typically seen. Rarely, transmigration of the FB can occur.

Project description:ImportanceAlthough various clinical prediction models (CPMs) have been described for diagnosing pediatric foreign body aspiration (FBA), to our knowledge, there is still no consensus regarding indications for bronchoscopy, the criterion standard for identifying airway foreign bodies.ObjectiveTo evaluate currently available CPMs for diagnosing FBA in children.Data sourcesPerformed in Ovid MEDLINE, Ovid Embase, PubMed, Web of Science, and CINAHL database with citation searching of retrieved studies.Study selectionPrediction model derivation and validation studies for diagnosing FBA in children were included. Exclusion criteria included adult studies; studies that included variables that were not available in routine clinical practice and outcomes for FBA were not separate or extractable.Data extraction and synthesisWe followed the Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modeling Studies and the Prediction Model Risk of Bias Assessment Tool framework. Data were pooled using a random-effects model.Main outcomes and measuresThe primary outcome was the diagnosis of FBA as confirmed by bronchoscopy. Characteristics of CPMs and individual predictors were evaluated. The final model presentation with available measures of performance was provided by narrative synthesis. A meta-analysis of individual predictor variables and prediction models was performed.ResultsAfter screening 4233 articles, 7 studies (0.2%; 1577 patients) were included in the final analysis. There were 6 model derivation studies and 1 validation study. Air trapping (odds ratio [OR], 8.3; 95% CI, 4.4-15.5), unilateral reduced air entry (OR, 4.8; 95% CI, 3.5-6.5), witnessed choking (OR, 3.1; 95% CI, 1.0-9.6), wheezing (OR, 2.5; 95% CI, 1.2-5.2), and suspicious findings suggestive of FBA on radiography (OR, 18.5; 95% CI, 5.0-67.7) were the most commonly used predictor variables. Model performance varied, with discrimination scores (C statistic) ranging from 0.74 to 0.88. The pooled weighted C statistic score of all models was 0.86 (95% CI, 0.80-0.92). All studies were deemed to be at high risk of bias, with overfitting of models and lack of validation as the most pertinent concerns.Conclusions and relevanceThis systematic review and meta-analysis suggests that existing CPMs for FBA in children are at a high risk of bias and have not been adequately validated. No current models can be recommended to guide clinical decision-making. Future CPM studies that adhere to recognized standards for development and validation are required.

Project description:BACKGROUND:An orbitocranial injury with a penetrating Intraorbital Foreign Body (IOFB) is listed as a rare cause of penetrating trauma. Since this type of trauma is considered a surgical emergency, taking a thorough history along with careful examination to find out the mechanism and cause of the trauma is crucial towards correct diagnosis and management of the disease. CASE PRESENTATION:A 35-year-old male patient was presented to the ER with an occupational craniofacial injury because of an IOFB. The patient underwent an extra-dural orbitocranial craniotomy procedure to remove the foreign body. Interestingly, a plastic foreign body (a piece of a plastic pipe) was removed from the orbital cavity, which was suspected to be a fractured orbital bone, at first place. CONCLUSION:In this study, we demonstrated that plastics could mimic bone structure in a Computerized Tomography (CT) scan leading to possible initial misdiagnosis. Hence high clinical suspicion is necessary for the correct diagnosis of such cases. However, despite the prompt intervention, our patient ended up with permanent vision loss in his injured eye.

Project description:IntroductionAlthough intra-orbital foreign bodies (IOrFBs) are commonly seen in daily ophthalmology practice, rarely, they can have very unusual clinical presentations, especially nonmetallic FBs.Presentation of caseA 33-year-old male presented with sudden onset right lower lid swelling and tearing. He was initially tolerating the symptoms, however, it got progressively worse, so he came two weeks after the initiation of symptoms. His eye vitals were within normal limit, including the visual acuity of 6/6 OU. Additionally, slit lamp and fundus examinations were benign. Concern was for infectious etiology with unclear source. After a lengthy conversation, he recalled falling on the ground with face down about 16 months ago. However, he stated that he had remained asymptomatic and never went for treatment after the incident. Non-contrast CT of head and orbit showed hyperdense tract in medial aspect of right eye adjacent to the globe, piercing across the bilateral ethmoidal sinuses. Thus, a diagnosis of retained IOrbFB was made. He underwent surgery where a 5cm rotten wood was extracted. Post-surgical course was uncomplicated. Not all penetrating intra-orbital foreign bodies present immediately after the incident. In our case the patient remained asymptomatic for 16 months.ConclusionTherefore, when dealing with an ocular infection of unclear source, clinicians should ask about distant histories of ocular or facial injuries to assess intraocular foreign bodies.
