Suppurative thyroiditis caused by ingested fish bone in the thyroid gland: a case report on its diagnostics and surgical therapy.

BACKGROUND: Accidental ingestion of fish bone is a common cause of otolaryngological emergency. Migration of the ingested bone into the thyroid gland, however, occurs very rarely. The associated clinical presentation, symptoms and duration of discomfort are also highly variable between patients and can be diagnostically challenging. CASE PRESENTATION: Here, we report the case of a 71-year-old female patient presenting with an ingested fish bone that migrated into the right thyroid lobe as a rare cause of suppurative thyroiditis with the clinical features of sepsis. We outline the diagnostic approach, peri- and intraoperative management as well as complications. It is proposed that besides endoscopy, imaging methods such as ultrasound or computed tomography may be necessary to verify the diagnosis and location of an ingested fish bone. Prompt surgical removal of the foreign body and resection of the infectious focus is recommended to minimize the risk of local inflammation, recurrent nerve lesions and septic complications arising from the spread of infection. CONCLUSION: Fish bone migration into the thyroid gland is an extremely rare event, the successful detection and surgical management of which can be achieved through a careful interdisciplinary approach.

INTRAOCULAR LENS MALPOSITION AFTER SUTURELESS INTRASCLERAL FIXATION OF INTRAOCULAR LENS.

PURPOSE: To introduce cases of intraocular lens (IOL) malposition after sutureless intrascleral fixation. METHODS: We retrospectively analyzed the medical records of patients who underwent sutureless intrascleral fixation. Cases with postoperative IOL requiring reoperation were analyzed further. RESULTS: Of the 48 eyes that underwent sutureless intrascleral fixation of their IOL, seven eyes had postoperative IOL malposition and underwent reoperation (14.6%). There was no difference in the clinical results between the intravitreal (33 eyes) and intracameral (15 eyes) techniques, but IOL malposition requiring reoperation was more frequent in the latter (2 cases [6.1%] vs. 5 cases [33.3%], P = 0.024). In the 7 eyes that required reoperation, the visual acuity before reoperation was 0.9 ± 0.6 logMAR (20/159), whereas astigmatism was -4.8 ± 3.2 diopters. The visual acuity and cylindrical error improved to 0.1 ± 0.2 logMAR (20/25) and -2.4 ± 2.3 diopters, respectively, at 6 months after the secondary operation. CONCLUSION: In 14.6% of the patients who underwent sutureless intrascleral fixation of the IOL, IOL malposition developed and reoperation was performed. With the intravitreal technique, which uses a wider space than the intracameral technique, the frequency of postoperative IOL malposition could be reduced.

Stent in Left Renal Vein Stuck at the Opening of Tricuspid Valve.

A 41-year-old male patient presented to the hospital with chest tightness and intermittent chest pain. Cardiac ultrasonography revealed a metallic foreign body in the right ventricle, accompanied by tricuspid insufficiency. A chest computed tomographic scan further confirmed a foreign body stuck at the opening of the tricuspid valve. The 14- × 40-mm stent was removed from the right ventricle through a thoracotomy. The patient had undergone left renal venous stenting 1 month earlier for treatment of nutcracker syndrome. Thus, for patients who have received left renal venous stenting for treatment of nutcracker syndrome, clinicians should pay due attention to stent graft migration.

Assessment of Silicone Particle Migration Among Women Undergoing Removal or Revision of Silicone Breast Implants in the Netherlands.

Importance: Silicone breast implants have been on the market for breast augmentation or breast reconstruction for approximately 60 years but may lead to medical complications, also called breast implant illness. Objective: To evaluate the existence of silicone gel bleed and migration over a long time period, including the period in which the newer cohesive silicone gel breast implants were used. Design, Setting, and Participants: In this single-center case series, capsule tissue and lymph node samples were collected from women who underwent removal or revision of silicone breast implants from January 1, 1986, to August 18, 2020, and data were extracted from the pathological reports and revision of the histology if data were missing. All tissues were examined using standard light microscopy, some extended with modified oil red O staining and energy-dispersive radiographic spectroscopy. A total of 365 women had capsular tissue removed, including 15 patients who also had lymph nodes removed, and 24 women had only lymph nodes removed. Data were analyzed from January to May 2021. Exposures: Silicone breast implants. Main Outcomes and Measures: The main outcome was presence or absence of silicones inside or outside the capsule. One-way analysis of variance was used to determine significance between groups. Results: Among a total of 389 women with silicone breast implants (mean [SD] age, 50.5 [11.2] years), 384 women (98.8%) had silicone particles present in the tissues, indicating silicone gel bleed. In 337 women (86.6%), silicone particles were observed outside the capsule (ie, in tissues surrounding the capsule and/or lymph nodes), indicating silicone migration. In 47 women (12.1%), silicone particles were only present within the capsule. In 5 women (1.2%), no silicone particles were detected in the tissues. Patients were divided into 2 groups, with 46 women who received cohesive silicone gel breast implants and 343 women who received either an older or a newer type of breast implant. There were no differences in silicone gel bleed or migration between groups (silicone detected outside or inside capsule: 44 women [95.7%] vs 340 women [99.1%]; P = .19). Conclusions and Relevance: In this case series including women with noncohesive or cohesive silicone gel breast implants, silicone leakage occurred in 98.8% of women, indicating silicone gel bleed, and in 86.6% of women, migration of silicone particles outside the capsule was detected.

Inferior Vena Cava Filter Migrated to Left Ventricle.

Inferior vena cava (IVC) filters have been widely used to prevent pulmonary emboli in patients with venous thromboembolism. Here we report a rare case of complete pericardial tamponade with severe mitral and tricuspid valve regurgitation due to a fractured IVC filter. A 38-year-old male came to our emergency department with a 19-day history of progressive chest tightness. Chest x-ray revealed a tethering catheter fractured at the level of the junction of the superior vena cava and the right atrium. We performed open surgery and discovered that a steel wire had punctured the atrioventricular septum, the mitral valve, and finally the posterior wall of the left ventricle. The patient recovered quite well and was discharged after 1 week.

Removal of Unusual Foreign Metal Object (Nail) from the Right Ventricle of Human Heart: A Case Report.

Migration of foreign bodies (FB) with the blood flow to the heart is a rare, but very alarming condition as it may lead to life-threatening complications and death. Objects that are larger than 5 mm in diameter and/or irregular in shape are recommended for removal from extra- and intracardiac areas to prevent incurable embolization. Surgical extraction of intracardiac objects is a serious surgical challenge associated with difficulties to operate, during the continuous movement of the heart, and identify the exact FB location. Early diagnosis and timely removal of FBs are crucial treatment factors for this rare case resolution. We report a case of accidental migration of a metal FB object (nail) about 1.0*0.3 cm from the right neck area jugular vein to the right ventricle apex in the heart. The FB localization was accurately detected using Bi-plane transesophageal echocardiography (TEE) with a special comet-tail artifact. TEE provided valuable information before surgery, and the nail was successfully removed through open-heart surgical procedures and cardiopulmonary bypass (CPB). Postoperative tests indicated no complications.

Multimodal Imaging Characteristics of a Migrating Oropharyngeal-Spinal Foreign Body in a Cat.

A 2.5 yr old female spayed domestic shorthair presented for acute tetraparesis, dull mentation, and fever. MRI and computed tomography identified a thin linear foreign body extending from the caudal nasopharynx through the atlanto-occipital joint and cervicomedullary junction. Signal changes within the musculature were consistent with myositis, edema, and abscessation. Inflammation and edema surrounded the foreign body, and a dorsal cervical myelopathy extended caudally to the level of C6. Computed tomography attenuation values of the foreign body were most consistent with plant material. Euthanasia was performed; postmortem dissection of the soft palate confirmed a plant stem with abscess.

Comparison of imaging techniques to detect migrating foreign bodies. Relevance of preoperative and intraoperative ultrasonography for diagnosis and surgical removal.

OBJECTIVE: To report the relative sensitivity of different diagnostic imaging (DI) techniques to detect migrating foreign bodies (FB) in subcutaneous and underlying soft tissue structures of dogs and evaluate the value of intraoperative ultrasonography (intraop-US). STUDY DESIGN: Retrospective study. SAMPLE POPULATION: Forty-one dogs. METHODS: Medical records (2007-2019) of dogs that underwent surgery for a chronic abscess or draining tract were included when preoperative US (preop-US), computed tomography (preop-CT), or preop-MRI, and at least 6 months of follow-up information were available. Collected data included the DI techniques used, DI findings, and surgical findings. The relative sensitivity of each preoperative DI (preop-DI) technique was calculated. Dogs were divided into two groups, dogs that underwent only a preop-DI examination (group A) and dogs that underwent an additional intraop-US (group B). The success rates for FB surgical removal were compared between groups. RESULTS: The relative sensitivity of preop-US and preop-CT/MRI was 88% (95% CI, 70%-95.8%) and 57.1% (95% CI, 32.6%-78.6%), respectively. The success rate for FB removal was higher in group B (89.5%) than in group A (59.1%; P = .038). Clinical resolution occurred in 90.2% of dogs for a median duration of follow-up of 4.2 years (6 months to 9.3 years). CONCLUSION: Preoperative US seems more suitable than preop-CT/MRI for detection of migrating FB in subcutaneous and underlying soft tissue structures. The use of intraop-US increases the success rate for FB surgical removal. CLINICAL SIGNIFICANCE: Intraoperative US should be used in combination with preop-US to increase the likelihood of migrating FB surgical removal in dogs.

Another Use for EUS: Removal of a Transesophageal-Migrated Mediastinal Foreign Body.

Removal of foreign bodies from the upper gastrointestinal tract, though a common occurrence, can be technically challenging and risky. We report the case of a young man that, after eating a pizza cooked in a wood-burning oven, reported a sense of foreign body. Though the first evaluation by fiberoptic laryngoscopy found no foreign body, after a few weeks, the patient was readmitted from the ER for worsening symptoms and fever. A CT scan showed a metallic mediastinal foreign body inside a large fluid collection. After multidisciplinary evaluation, an endoscopic removal was attempted by accessing the mediastinal collection through EUS-guided positioning of a Hot Axios™ stent. The cavity was drained by naso-esophageal suction. The foreign body was a fragment of the brush used to clean the oven. The patient is now doing well after 7 months.

Left ventricular perforation from a dislodged needle migrating via a pulmonary artery branch in an intravenous drug user.

Embolised needles causing injury to the right heart and cardiac tamponade has been reported before in intravenous drug users, but to our knowledge, this is the first reported case of a needle migrating via the pulmonary arterial system to cause perforation of the left ventricle. Appropriate utilisation of imaging modalities such as plain X-ray and point-of-care focused cardiac ultrasound can be vital and life-saving in the emergency setting, and the value of gated multidetector CT as a powerful tool for imaging moving structures is highlighted.

Successful laparoscopic management of a hepatic abscess caused by a fish bone.

BACKGROUND: Hepatic abscess is a rare condition but comes with heavy consequences if not diagnosed and managed properly. Early detection of this pathology is challenging because of the variety and lack of specificity of symptoms but is necessary for accurate management. CASE REPORT: We report a case of pyogenic liver abscess secondary to the migration of an ingested fish bone in a 74-year-old female. We used laparoscopic surgery to drain the abscess, remove the foreign body responsible and look for the perforation site. Parenteral antibiotherapy was added to the surgical treatment. CONCLUSION: Early diagnosis of hepatic abscess caused by the migration of a foreign body remains a challenge. In our opinion, laparoscopic surgery associated with antibiotics is the safest and most effective therapeutic option.

A rare case of fatal multi-organ polymer graft material and cholesterol embolization following aortic repair.

Ischemia is a common complication of various endovascular procedures including endovascular aortic aneurysm repair. Multiple mechanisms can contribute to the pathogenesis of ischemia: thrombosis, arterial dissection, graft malpositioning, cholesterol embolization, and polymer graft embolization which is an underrecognized complication. To the best of our knowledge, only 38 cases of polymer graft embolization have been reported in the literature. The phenomenon has been reported in different organs including brain, heart, lungs, kidneys, bowel, liver, and skin. We report a unique case of fatal simultaneous cholesterol and polymer graft embolization with subsequent ischemic infarction of multiple organs (liver, kidneys, spleen, pancreas, duodenum, and stomach) in a 76-year-old woman following endovascular repair for an enlarging thoracic aortic aneurysm.
