Airway epithelia express intrinsic antimicrobial and nutrient-sequestering factors, which contribute to the host defense of the respiratory tract. Hepcidin is an endogenous peptide hormone that serves as a key regulator of iron metabolism, and ferroportin and ZIP8 are iron transporters. All exhibit innate antimicrobial activity. The purpose of this pilot study is to determine if molecules involved in iron regulation are expressed within sinus epithelia and to compare levels of expression between patients with and without chronic rhinosinusitis (CRS). Sinus mucosa was obtained from patients with (n = 19) and without (n = 14) CRS. Real-time polymerase chain reaction following RNA extraction was used to quantify expression of hepcidin, ferroportin, and ZIP8 mRNA. Hepcidin, ferroportin, and ZIP8 were all detected in the sinus epithelia of patients with and without CRS. However, only ZIP8 was significantly changed in CRS, with a 2.5-fold mean increase in mRNA expression relative to controls (P = .005). These findings suggest that ZIP8 may play a role in the innate epithelial defense of the paranasal sinuses.

Objectives  The aim of this study was to identify the reasons for patient messages, phone calls, and emergency department (ED) visits prior to the first postoperative visit following discharge after endoscopic transnasal transsphenoidal (eTNTS) surgery. Design  This is a retrospective review of patients at a tertiary care academic center who underwent eTNTS for resection of a sellar region tumor between May 2020 and August 2021. Patient, tumor, and surgical characteristics were collected, along with postoperative, postdischarge, and readmission information. Regression analyses were performed to investigate risk factors associated with postdischarge phone calls, messages, ED visits, and readmissions. Main Outcome Measures  The main outcomes were the number of and reasons for phone calls, patient messages, and ED visits between hospital discharge and the first postoperative visit. We additionally determined whether these reasons were addressed in each patient's discharge instructions. Results  A total of 98 patients underwent eTNTS during the study period. The median length of hospital stay was 2 days (interquartile range [IQR]: 1-4 days), at which point most patients (82%) were provided with eTNTS-specific discharge instructions. First postoperative visit took place 9 days after discharge (IQR: 7-10 days). Within that time, 54% of patients made at least one phone call or sent at least electronic message and 17% presented to the ED. Most common reasons for call/message were nasal care, appointment scheduling, and symptom and medication questions. Conclusion  Through this work, we highlight the most common reasons for resource utilization via patient phone calls, messages, and ED visits among our cohort to better understand any shortfall or gap in the discharge process that may reduce these events.

Purpose

Spheno-orbital meningiomas are rare tumors, accounting for up to 9% of all intracranial meningiomas. Patients commonly present with proptosis, and visual deficits. These slow growing tumors are hard to resect due to extension into several anatomical compartments, resulting in recurrence rates as high as 35-50%. Although open surgical approaches have been historically used for resection, a handful of endoscopic approaches have been reported in recent years. We aimed to review the literature and describe a case of spheno-orbital meningioma with severe vision loss which was resected with an endoscopic endonasal approach achieving complete resolution of visual symptoms.

Methods

A systematic review of literature was conducted in accordance with the PRISMA guidelines. PubMed, Cochrane, and Web of Science databases were queried for spheno-orbital meningiomas resected via an endoscopic endonasal approach. Furthermore, the presentation, surgical management, and post-operative outcomes of a 53-year-old female with a recurrent spheno-orbital meningioma are described.

Results

The search yielded 26 articles, of which 8 were included, yielding 19 cases. Average age at presentation was 60.5 years (range: 44-82), and 68.4% of patients were female. More than half of the cases achieved subtotal resection. Common complications associated with endoscopic endonasal surgery included CN V2 or CN V2/V3 hypoesthesia. Following surgical intervention, visual acuity and visual field remained stable or improved in the majority of the patients.

Conclusion

Endoscopic approaches are slowly gaining momentum for treatment of spheno-orbital meningiomas. Further studies on the clinical benefits of this approach on patient outcomes and post-operative complications is warranted.
