... On the other hand, in an Italian study of 901 COVID-19 patients, after adjustment for age, sex, and comorbidities, isolated neurological symptoms increased the chance of survival, but nearly one-third of these symptoms comprised dysgeusia, anosmia, or syncope [36]. Of these, anosmia was associated with a nearly 7-fold decrease in the risk of death among more than 11,000 patients with COVID-19 included in a large meta-analysis of 26 studies [37]. A recent Brazilian retrospective cohort study that included 613 patients with COVID-19 showed that, apart from older age and a requirement for mechanical ventilation, patients with encephalopathy had a significantly higher risk of death, but those with anosmia had a lower risk of dying [6]. ...
... The following data were collected: patient demographics, Charlson comorbidity index (CCI) [24], tumor variables, five-item modified frailty index (mFI-5) [25,26], body mass index (BMI) [27], and treatment modalities. Preoperative complete blood count and albumin level were obtained within a week before surgery. ...
... The prevalence of pituitary adenomas in population based studies is between 78 and 166 cases per 100,000 [2][3][4][5]. However pediatric cases represent only ∼5% of all pituitary adenomas [6][7][8]. ...
... This technology greatly eliminates the use of implantable device supply leads [35,[37][38][39]59]. Recently, Abiri et al. developed a transmitter-centered control system for wireless power transfer with sufficient power to cardiac pacing [60]. Under the device safety conditions, the device was validated using a computational model. ...
... An interesting study by Goshtasbi et al. 19 queried online ratings and comments from several patient rating sites of identified American fellowship-trained rhinologists at academic institutions. They queried Google, Healthgrades, Vitals, and RateMD and created a rating score system 1-5. ...
... The most recent data show the risk of CSF leak to be in the order of 3.5%-5.0%. [1][2][3] Conventionally accepted factors contributing to CSF leak were the defect size, number of reconstructed layers, type of graft, body mass index (BMI), and surgeon experience. The development of the pedicled nasoseptal flap has led to a significant decrease in the occurrence of CSF leak after anterior skull base reconstruction. ...
... Inclusion criteria were surgically treated adults aged 18 years and older who, in the period from 2004 to 2016, had been diagnosed with International Classification of Diseases for Oncology, Third Edition (ICD-O-3) histology codes for PA (8140, 8202, 8260, 8270, 8271, 8272, 8280, 8281, 8290, 8300), 9 with benign histological confirmation via microscopic examination. To avoid potential reporting errors, exclusion criteria consisted of PAs with a size greater than 98 mm (many centers coded "99" and "100" for an unknown tumor size), tumors coded outside the pituitary gland (topographical code 75.1), and any patients who had prior malignancy. ...
... However, only two patients received concomitant RT + CT and the other six RT (combined with surgery in two cases). This outcome corroborates findings by Lehrich et al., in a study involving 440 patients, indicating that induction chemotherapy may not provide survival benefits in SNUC patients [20]. As for many other subsets of SNM, further studies are warranted also for SNUC. ...
... The indication and timing of surgical decompression remains controversial and the role of conservative management remains unresolved. While it is recognised that visual outcomes are improved if surgery is performed within 7 days of presentation [5,8,16,19,23,24], conservative management for patients with less severe and non-progressive visual symptoms can have very good long-term results [7,9,10,21,22]. ...
... The 3 mm diameter wireless pacer was sufficiently powered for continuous pacing using 1.26 mW of power from a 40 mm diameter transmitter while remaining nearly 23 times below the SAR safety limits. This power requirement may be fulfilled via a rechargeable battery with charging intervals of over 5 months or up to years, depending on the pacing demand [48]. ...
