Study Design Prospective cohort study. Objectives In spine surgery, accurate screw guidance is critical to achieving satisfactory fixation. Augmented reality (AR) is a novel technology to assist in screw placement and has shown promising results in early studies. This study aims to provide our early experience evaluating safety and efficacy with an Food and Drug Administration-approved head-mounted (head-mounted device augmented reality (HMD-AR)) device. Methods Consecutive adult patients undergoing AR-assisted thoracolumbar fusion between October 2020 and August 2021 with 2 -week follow-up were included. Preoperative, intraoperative, and postoperative data were collected to include demographics, complications, revision surgeries, and AR performance. Intraoperative 3D imaging was used to assess screw accuracy using the Gertzbein-Robbins (G-R) grading scale. Results Thirty-two patients (40.6% male) were included with a total of 222 screws executed using HMD-AR. Intraoperatively, 4 (1.8%) were deemed misplaced and revised using AR or freehand. The remaining 218 (98.2%) screws were placed accurately. There were no intraoperative adverse events or complications, and AR was not abandoned in any case. Of the 208 AR-placed screws with 3D imaging confirmation, 97.1% were considered clinically accurate (91.8% Grade A, 5.3% Grade B). There were no early postoperative surgical complications or revision surgeries during the 2 -week follow-up. Conclusions This early experience study reports an overall G-R accuracy of 97.1% across 218 AR-guided screws with no intra or early postoperative complications. This shows that HMD-AR-assisted spine surgery is a safe and accurate tool for pedicle, cortical, and pelvic fixation. Larger studies are needed to continue to support this compelling evolution in spine surgery.

Rosacea is a facial inflammatory dermatosis that is linked with various systemic illnesses. With regards to the eye, rosacea patients have been described to manifest ocular surface changes, such as blepharitis and conjunctivitis. However, studies that examine the association of rosacea with a wider array of ocular diseases are limited. Thus, our aim was to identify the range of ocular comorbidities in the Korean patient population and create a reference data set. A multi-institutional, case-control study was conducted, where 12,936 rosacea patients and an equal number of sex- and age-matched control subjects were extracted over a 12-year period. We were able to discover a notable association between rosacea and blepharitis (adjusted odds ratio (aOR) 3.44; 95% confidence interval, 2.71–4.36, p < 0.001), conjunctivitis (aOR 1.65; 95% CI, 1.50–1.82, p < 0.001), glaucoma (aOR 1.93; 95% CI, 1.70–2.20, p < 0.001), dry eye syndrome (aOR 1.89; 95% CI, 1.70–2.09, p < 0.001), and chalazion (aOR 3.26; 95% CI, 1.41–7.57, p = 0.006) from logistic regression analysis. Female subjects and individuals younger than 50 exclusively showed higher odds for chalazion. Our study suggests that ocular comorbidities (i.e., glaucoma, dry eye syndrome, and chalazion as well as blepharitis and conjunctivitis) are more prevalent among Koreans with rosacea. Clinicians should proactively check ocular symptoms in rosacea and employ joint care with an ophthalmologist in cases of need.

Objective: This study was conducted to evaluate the association between neurodegenerative dementia and herpes zoster infection (HZI) using a national sample cohort. Methods: From the national cohort study conducted by the Korean National Health Insurance Service, we extracted data for patients with neurodegenerative dementia and for 1:4 matched control participants and searched the patient histories for HZI. Results: The adjusted odds ratio (OR) for HZI was 0.90 (95% CI = 0.84-0.97) in the dementia group. According to the subgroup analysis, the adjusted OR for HZI was 0.91 (95% confidence interval [CI] = 0.83 -1.00) in the < 80 years old group, 0.88 (95% CI = 0.78 -1.00) in the ≥ 80 years old group, 0.77 (95% CI = 0.66-0.89) in men and 0.96 (95% CI = 0.88 -1.05) in women. Conclusions: We concluded that HZI does not increase the risk of neurodegenerative dementia in individuals of any age or of either sex.
