Treatment of Meningiomas Involving the Optic Canal with Endoscopic Transnasal Decompression of the Optic Nerve.

BACKGROUND: Management of patients with optic nerve sheath meningiomas (ONSMs) is controversial and the treatment strategy in this patient group is still up for discussion. Transnasal endoscopic orbital and optic nerve decompression aims to reduce the pressure in the orbit and on the optic nerve and thereby prevent vision loss. This article presents material from 7 cases of transnasal endoscopic orbital decompression. METHODS: The study design is a retrospective cohort study. The aim was to include all patients with a meningioma residing along the nerve sheath and who were operated using endoscopic transnasal decompression of the orbit and if needed the optic canal at Odense University Hospital. Data from the medical records were collected and pre- and postoperative eye examinations were compared. In addition, it was recorded whether there were complications to the procedure and whether additional treatments were given. RESULTS: In total, 4 women and 3 men were included in the study. Four out of 7 patients experienced improvement in vision after the operation. One patient experienced unchanged vision and 2 patients experienced deterioration of vision after surgery. CONCLUSIONS: The current report of 7 patients with ONSM shows promising results for this surgical procedure as 4 out of 7 patients experienced improvement in their vision at follow-up examinations. The 2 patients who experienced deterioration of vision already had severely reduced vision preoperatively, which indicates that surgery should be considered before the vision becomes significantly reduced.

Endonasal Endoscopic Approach for Minimally Invasive Orbital Decompression in Nonthyroid Proptosis-A Scoping Review.

OBJECTIVE: The endoscopic endonasal approach (EEA) was originally performed to treat thyroid orbitopathy and proptosis. Since then, this approach also has been used to treat other causes of proptosis. This review systematically identifies surgical outcome and complication rates in patients without thyroid proptosis who underwent endoscopic endonasal orbital decompression. METHODS: Databases were searched using the following search terms: orbital disease, surgical decompression, and endoscopic endonasal approach. Two independent reviewers screened all abstracts and titles for relevance and all articles passing this screen were subjected to full-text review. To assess risk of bias, we used ROBINS-I (Risk Of Bias in Non-randomized Studies-of Interventions). RESULTS: Eight studies with a total of 74 patients with nonthyroid proptosis were included. Pre- and postoperative eye examination was performed in all studies, but the extent of examination was varying. With a mean age of 35.7 years, most patients were adolescent, and most pathologies induced unilateral proptosis Complications to EEA for orbital decompression were transient diplopia (5 patients/6.8%), transient facial dysesthesia (2 patients/2.7%), ptosis (1 patient/1.4%), infarction (1 patient/1.4%), sinus obstruction (1 patient/1.4%), and enophtalmos (1 patient/1.4%). The authors reported successful reduction of proptosis in all but 2 patients (97.2%), and only 2 authors reported a need for secondary decompression. CONCLUSIONS: Medial orbital decompression using EEA is a feasible approach for orbital decompression in patients with nonthyroid proptosis. While being comparable in primary outcome to transorbital approaches, the EEA seems superior in terms of complication rates.

[Orbital decompression in non-thyroid-associated diseases].

Hypoxia triggers hypoxia-inducible factor (HIF). Not only hypoxia triggers downstream HIF target genes for transcription, as intermittent hyperoxia also possesses similar capabilities, suggesting that fluctuations in oxygen availability may be equally important for inducing HIF transcription. This review describes some of the mechanisms, whereby intermittent hyperbaric hyperoxia may explain some of the observations during hyperbaric oxygen therapy such as enhanced wound healing, angiogenesis and tissue healing, and concludes that oxidative stress enhances certain antibiotics in infection control.

Long-term follow-up of RET Y791F carriers in Denmark 1994-2017: A National Cohort Study.

BACKGROUND AND OBJECTIVES: Recently, a comprehensive study presented evidence that a long-disputed REarranged during Transfection (RET) variant, RET Y791F, should be classified as nonpathogenic. In spite of this, several subsequently published papers, including the revised American Thyroid Association guidelines for medullary thyroid carcinoma, refer to the variant as pathogenic. This study presents data from a unique national Danish cohort of RET Y791F carriers who have been followed by watchful waiting instead of being subjected to early thyroidectomy, to determine if any carrier shows evidence of multiple endocrine neoplasia 2A (MEN2A) at long-term follow-up. METHODS: A national cohort of all patients tested for RET mutations in Denmark from September 1994 to October 2017 was searched for carriers of RET Y791F. Medical records and laboratory reports of carriers were reviewed for signs of MEN2A at latest follow-up (medullary thyroid carcinoma, primary hyperparathyroidism, pheochromocytoma, cutaneous lichen amyloidosis, or Hirschsprung's disease). RESULTS: In total, twenty RET Y791F-carriers were identified, none of whom showed any evidence of MEN2A, despite an age range from 7 to 87 years. CONCLUSIONS: Our national cohort study of all Danish RET Y791F carriers substantiates the claim that the RET Y791F variant is nonpathogenic.

Intranasal corticosteroids compared with oral antihistamines in allergic rhinitis: A systematic review and meta-analysis.

BACKGROUND: Intranasal corticosteroids (INS) (corticosteroid nasal sprays) and oral antihistamines (OA) are two of the most common treatments for patients with allergic rhinitis (AR). To our knowledge, there are no systematic reviews on this topic including trials published after 2007. OBJECTIVE: To compare INS with nonsedating OAs as treatments for AR. METHODS: The systematic review and meta-analysis were based on the Grades of Recommendation, Assessment, Development, and Evaluation principles and the Patient, Intervention, Comparison, and Outcome approach. Primary literature was searched up to January 22, 2015. Criteria for eligibility were randomized controlled trials that compared the efficacy and/or adverse effects of INS and OA in patients with AR. Continuous outcome data were analyzed by using standardized mean differences (SMD) for multiple outcome measures, and mean differences in the case of a single study or outcome. Pooled estimates of effects, 95% confidence interval (CI), were calculated by using random-effects models. RESULTS: The meta-analysis included five randomized controlled trials with a total of 990 patients. INS were superior to OAs in improving total nasal symptoms score (SMD -0.70 [95% CI, -0.93 to -0.47]) and in relieving the following: nasal obstruction (SMD -0.56 [95% CI, -0.82 to -0.29]), rhinorrhea (SMD -0.47 [95% CI, -1.00 to 0.05]), nasal itching (SMD -0.42 [95% CI, -0.65 to -0.18]), sneezing (SMD -0.52 [95% CI, -0.73 to -0.32]), and quality of life mean difference -0.90 [95% CI, -1.18 to -0.62]). There was no difference in relief of ocular symptoms (SMD -0.08 [95% CI, -0.23 to 0.08]). In addition, four randomized controlled trials were included in a narrative analysis. The results in the narrative analysis were comparable with those found in the meta-analysis. CONCLUSION: INS were superior to OAs in improving nasal symptoms and quality of life in patients with AR.

[Diagnostic challenges during cranial osteonecrosis elucidation]. / Diagnostiske udfordringer under udredning af kranial osteonekrose.

This is a case report of an 81-year-old male with severe headaches caused by osteonecrotic lesions in the frontotemporal part of the skull. Initially, metastatic lesions were suspected but other causes had to be identified because of chronic inflammation evidence in all biopsies. In the diagnostic process a discussion of missed malignancy, morbus Paget and steroid induced avascular necrosis are presented.

[Results of functional endoscopic sinus surgery]. / Resultater af funktionel endoskopisk sinuskirurgi.

INTRODUCTION: Chronic rhinosinusitis (CRS) and polyposis cavi nasi (PCN) are two frequently occurring, disabling diseases. Many international studies have obtained very good results with the functional endoscopic sinus surgery (FESS) technique in cases of resistance to conservative treatment. This is the first study in Denmark that attempts to compare Danish results with international results. MATERIALS AND METHODS: The study included 31 patients operated on in the period 1 January-31 December 2002 in the ENT Department, Aarhus University Hospital. After a retrospective journal study, all patients were followed up on by means of a postoperative cross-sectional examination, with a questionnaire and endoscopic inspection of the nasal cavity. RESULTS: We found significant improvement as regarded sense of smell, degree of nasal obstruction, rhinorrhoea and facial pain. The endoscopic inspections showed a significant reduction in nasal polyps. Eighty-six percent of the patients said they would recommend the same kind of surgery to a similar patient. CONCLUSION: The study showed good results using functional endoscopic sinus surgery on Danish patients with CRS and PCN. The Danish population of those suffering from CRS and PCN undergoing surgery was not comparable to those in international studies. The study raised questions concerning the lack of national references and database programme.
