Foreign body (FB) aspiration occurs less frequently in adults than in children. Among the complications related to FB aspiration, pneumothorax is rarely reported in adults. Although the majority of FB aspiration cases can be diagnosed easily and accurately by using radiographs and bronchoscopy, some patients are misdiagnosed with endobronchial tumors. We describe a case of airway FB that mimicked an endobronchial tumor presenting with pneumothorax in an adult. A 77-year-old man was referred to our hospital due to pneumothorax and atelectasis of the right upper lobe caused by an endobronchial nodule. A chest tube was immediately inserted to decompress the pneumothorax. Chest computed tomography with contrast revealed an endobronchial nodule that was seen as contrast-enhanced. Flexible bronchoscopy was performed to biopsy the nodule. The bronchoscopy showed a yellow spherical nodule in the right upper lobar bronchus. Rat tooth forceps were used, because the lesion was too slippery to grasp with ellipsoid cup biopsy forceps. The whole nodule was extracted and was confirmed to be a FB, which was determined to be a green pea vegetable. After the procedure, the chest tube was removed, and the patient was discharged without any complications. This case highlights the importance of suspecting a FB as a cause of pneumothorax and presents the possibility of misdiagnosing an aspirated FB as an endobronchial tumor and selecting the appropriate instrument for removing an endobronchial FB.

To identify and localize an intraorbital wooden foreign body is often a challenging radiological issue; delayed diagnosis can lead to serious adverse complications. Preliminary radiographic interpretations are often integrated with computed tomography and magnetic resonance, which play a crucial role in reaching the correct definitive diagnosis. We report on a 40 years old male complaining of pain in the right orbit referred to our hospital for evaluation of eyeball pain and double vision with an unclear clinical history. Computed tomography and magnetic resonance scans supposed the presence of an abscess caused by a foreign intraorbital body, confirmed by surgical findings.

Pencil core granuloma is characterized by a delayed foreign-body reaction against retained fragments of pencil lead. Previous case reports presented pencil core granuloma resembling malignant melanoma, haemangioma, or soft tissue sarcoma. We present a case of pencil core granuloma arising from the palm 25 years after the initial injury. The patient presented a bluish nodule that had been present over 25 years before. The nodule initially measured 5 mm in diameter. However, five years before presentation, it suddenly enlarged to the size of 30 mm during six months. Computed tomography (CT) of the lesion revealed a linear radiopaque structure of 8 mm long with a mass on its distal end. Surgical resection revealed a bluish muddy mass and pencil lead. Histological examination revealed degenerative tissue with calcification surrounded by massive amounts of black granular material in the middle and lower dermis.

Pva Hydrogel

Background: Hemiarthroplasty using a polyvinyl alcohol (PVA) hydrogel synthetic implant has been suggested as a good alternative to arthrodesis for the treatment of hallux rigidus. However, failure rates as high as 20% have been recorded. Purpose: To characterize the pathological processes in bone, cartilage, and the synovial membrane after PVA hemiarthroplasty in an ovine model with 6 months of follow-up. Study Design: Controlled laboratory study. Methods: A unilateral osteochondral defect (8-mm diameter × 10-mm depth) was made in the medial femoral condyle in 6 sheep. Animals were randomized to receive a PVA implant (n = 4) or to have an empty defect (n = 2) and were monitored for 6 months. Patellofemoral radiographs were obtained at monthly intervals, and quantitative computed tomography was performed at the end of the study. After death, the joints were macroscopically evaluated and scored. Osteochondral and synovial membrane histological findings were assessed using modified Osteoarthritis Research Society International (OARSI) and aseptic lymphocyte-dominated vasculitis-associated lesion (ALVAL) scoring systems. Immunohistochemistry using Iba1 was performed to evaluate activated macrophage infiltration. Results: Overall, 2 sheep with PVA implants were euthanized at 1 and 5 months because of uncontrollable pain and lameness (failed implants). Quantitative computed tomography showed that sheep with failed implants had 2.1-fold more osteolysis than those with successful implants. The sheep with failed implants had osteoarthritis with extensive glycosaminoglycan loss and cartilage fibrillation of the condyle and opposing tibial surface on histological examination. A foreign body reaction with severe chronic lymphoplasmacytic and granulomatous inflammation with giant cells was detected surrounding the implant. The synovial membrane ALVAL score was 9 of 19 and 14 of 19 in failed implants with synovial hyperplasia and lymphoplasmacytic and macrophage infiltration. In contrast, the synovial membrane in successful implants and empty defects was normal (ALVAL score = 0/19). Immunolabeling for Iba1 in failed implants confirmed extensive and dense macrophage infiltration within the condyle and synovial membrane, with the highest immunoreactive score (9/9). Conclusion: PVA hydrogel implants had a 50% failure rate with uncontrollable pain, severe osteolysis, inflammation, and foreign body reactions. Clinical Relevance: The failure rate and pathological characteristics of the PVA implants suggest that their use should not be continued in human patients without further in vivo safety studies.

AbstractA 12 year old male Fox Terrier (case 1) and a one year old female Poodle (case 2) were presented with a history of dysorexia and vomiting, and case 2 also with distress associated with eating. Both dogs were diagnosed with acute pancreatitis based on clinical signs, blood analysis and ultrasonography which revealed the presence of a vegetable foreign body in the proximity of the pancreatic right lobe. Laparatomy enabled the gramineae awns to be removed which led to full resolution of clinical signs. We believe that these are the first reported cases of acute pancreatitis due to grass awns.

A dog was referred to Alta Vista Animal Hospital with a porcupine quill penetrating the right ventricle. The presenting complaint was tachypnea and dyspnea secondary to bilateral pneumothorax. Computed tomography revealed bilateral pneumothorax without evidence of quills. A median sternotomy was performed and the quill was removed. The dog recovered uneventfully. Quill injuries are common in dogs; however, intracardiac quill migration is rare. Dogs without evidence of severe cardiac injury secondary to intracardiac foreign bodies may have a good prognosis.

Transanal rectal foreign body implies that a foreign body has been inserted transanally due to sexual orientation or other reasons and cannot be removed. Such cases require emergency measures because foreign bodies often present difficulties in manual removal or endoscopic removal and may even require surgery when peritonitis due to gastrointestinal perforation occurs. We report a patient in our hospital who had a rectal foreign body inserted into the deep part of the proctosigmoid that could be removed endoscopically. A 66-year-old man visited our hospital because of an eggplant which had been inserted into his rectum by his friend and could not be removed. Since plain abdominal computed tomography showed a foreign body thought to be an eggplant in the proctosigmoid, the foreign body was captured and removed with a snare under lower gastrointestinal endoscope guidance.

The paper describes a patient who ingested a piece of bone during his meal. A foreign body was suspected and admission to the hospital was recommended as well as esophagoscopy, which he refused. Approximately 48 hours after the meal, the patient was admitted to the hospital for increased temperature, neck pain, and swollen right side of neck. Assuming that the condition was a result of hypopharyngeal perforation cased by a foreign body, computed tomography was performed. A collection of pus was found in the lateral and anterior neck compartments with subcutaneous tissue edema, and a foreign body was found in the projection of the hypopharynx. A wide incision was made under general anesthesia and drainage was performed using surgical drains and nasogastric tube. Antibacterial therapy was also applied. The patient was dismissed from the hospital in good general condition. Complications involving a foreign body in the hypopharynx and/or esophagus require urgent attention and adequate diagnosis and therapy. A correct indication, good choice of surgical procedure and intensive antibacterial therapy increase the chance of cure in such patients. .
