Thyroid follicular dendritic cell sarcoma (FDCS) is an extremely rare malignancy that originates from follicular dendritic cells of the thyroid germinal centers. To the best of our knowledge, there are only 4 reported cases of thyroid FDCS in the English literature. Herein, we present the fifth case of FDCS of the thyroid gland. A 63-year-old woman presented with a painless midline neck mass, enlarging for the last 4 months. Physical examination revealed a 6-cm nonmobile, firm, multinodular thyroid mass with palpable cervical lymphadenopathy. Due to high suspicion for thyroid malignancy, the patient underwent total thyroidectomy with bilateral modified radical neck dissection. Histologic evaluations revealed sheets of storiform eosinophilic tumoral cells with prominent nucleoli containing multinucleated giant cells, and subsequent immunohistochemistry showed immunoreactivity for CD4, CD21, CD35, CD45 (LCA), and CD68. The patient was started on 6 cycles of doxorubicin, ifosfamide, and radiotherapy. She has had monthly thyroid ultrasonography and contrast-enhanced thoracoabdominal CT scan every 3 months for detecting potential recurrence and/or metastasis screening. Fortunately, 8 months after the operation, the patient is alive without any signs of local or distant metastasis.
Background and objectiveTracheostomy in coronavirus disease 2019 patients can be performed in cases of prolonged intubation or in patients with a known difficult airway. Tracheostomy is usually performed by two main approaches: open surgery or percutaneous endoscopic insertion. However, few studies have compared these two techniques in severe COVID-19 patients. The objective of the present study was to compare the efficacy of the two main methods of tracheostomy among patients with severe COVID-19 infection. We also aimed to investigate the impact of various lab data and medications on patient outcomes.
Materials and methodsWe included all symptomatic severe COVID-19 patients in need of prolonged mechanical ventilation. We examined the patients' past medical history, arterial blood gas (ABG) analysis, laboratory workups, and medication history. We calculated the PaO 2 /FiO 2 ratio as an index to evaluate the severity of acute respiratory distress syndrome (ARDS).
ResultsDuring the study period, 72 patients with severe COVID-19 underwent tracheostomy tube insertion. The average age of participants was 58.93 ±15.27 years; 44 (61.1%) were male and 28 (38.9%) were female. Of note, 54 (75.0%) patients passed away and only 18 (25.0%) survived. Among the survivors, 13 (29.5%) were men and five (17.9%) were women. The study showed a significantly higher mortality rate (23, 92.0%) among patients who underwent open surgery compared to those who received percutaneous surgery (31, 65.9%) (p=0.01).
ConclusionBased on our findings, percutaneous endoscopic tracheostomy seems to be the superior approach compared to open tracheostomy. Other predictive factors associated with patient outcomes included levels of HCO 3 , FiO 2 , PaCO 2 , and PaO 2 /FiO 2 ratio.
Monochorionic twins (MC) are at increased risk of CHDs, especially
acquired CHDs in twin-twin transfusion syndrome (TTTS). Multiple cardiac
abnormalities in MC twins with TTTS are to be expected due to cardiac
hemodynamic changes. Therefore, more attention to this group of patients
should be given regarding heart abnormalities.
A 30-year-old pregnant female presented to the emergency department with labor pain in her 39th week of pregnancy. Cesarean section under spinal anesthesia was the chosen route of delivery for this patient due to previous cesarean section in her first pregnancy. The delivery itself was uneventful but seven hours after the surgery, bilateral swelling of parotid glands were noted. Rehydration therapy and a single dose of hydrocortisone (100 mg IV route) were administered, and swellings were completely resolved on postoperative day 2. This is one of the rare cases of anesthesia mumps after spinal anesthesia, and we think rehydration therapy and the single dose corticosteroid may prove useful in these cases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
