Purpose:
To describe the surgical technique and clinical outcome of autologous retinal free flap transplantation for recurrent giant macular hole retinal detachment (MH RD) in a high myopia patient.Case summary: A 71-year-old female had undergone pars plana vitrectomy (PPV), internal limiting membrane peeling, and endolaser photocoagulation at the margin of the hole with silicone oil tamponade for repair of myopic MH RD. Silicone oil was removed at postoperative 4 months and the retina was properly attached. Unfortunately, the retina redetached with a large MH, which developed 8 years after surgery. The patient underwent 3-port PPV under general anesthesia. A retinal flap was harvested from the mid-periphery of the superior detached retina. The retina was cut along the marked edge of the retinal flap except for a small attachment part (hinge). After fluid-air exchange, the hinge of the retinal free flap was gently dissected and then placed on the macular area with a drop of viscoelastics. Endolaser treatment was performed around the retinal flap harvest site and silicone oil was injected at the end of surgery. The 1 week postoperative optical coherence tomography showed MH closure, which was stable at postoperative 9 months.
Conclusions
Autologous retinal free flap transplantation is an effective method as a surgical option for recurrent giant MH RD in high myopia patients.

This study examines how acquired capability for suicide, negative urgency, and social support effectuate a suicide attempt. Sixty-three adults having visited an emergency room due to a suicide attempt were studied. The results can be summarized as follows. First, there were no significant sex differences in acquired capability for suicide, negative urgency, and social support. Second, the correlation among suicidal ideation, acquired capability for suicide, negative urgency, social support, and suicide attempts was examined. Results showed that suicide attempts were significantly and positively correlated with suicide ideation, acquired capability for suicide, and negative urgency. However, social support and suicide attempts did not significantly correlate. Third, results of hierarchical regression analysis indicated that acquired capability for suicide and negative urgency significantly predicted suicide attempts even when suicide ideation was controlled, but social support did not significantly explain attempts. In other words, study results imply that suicide attempts increase when acquired capability for suicide and negative urgency are high. Study results offer empirical data for understanding the intrinsic characteristics of individuals attempting suicide.

Relapsing polychondritis is a rare rheumatologic disorder most commonly presenting as recurring episodes of inflammation in cartilaginous tissues. Auricular chondritis with red ears resembling cellulitisis the most common clinical manifestation. Other manifestations include arthritis, nasal chondritis, and ocular, pulmonary, and cardiovascular disease. Here we report the case of a 54-year-old female patient with relapsing polychondritis and associated scleritis. On histologic examination, the auricle, including cartilaginous tissues, showed loss of the normal basophilia of cartilage and perichondrial infiltration of inflammatory cells. The patient was treated with systemic steroids. Symptoms in both auricles were reduced, scleritis developed, and ocular symptoms were waning.

Purpose:
An inverse relationship between cancer and neurodegenerative disease, which presents the possibility of a reduced risk of dementia in cancer patients, has been suggested previously. However, a nationwide longitudinal population-based study of specific types of cancer with due consideration of treatment effects has not been conducted.
Materials and Methods:
This nationwide population-based cohort study used data obtained in a 12-year period (January 2007- December 2018) in the Korean National Health Insurance claims database. All female breast cancer patients (age ≥ 50 years) diagnosed between 2009 and 2010 were included after excluding those with physician visits for any cancer during a 2-year period (2007-2008). Patients with senile cataract constituted the control group. The main study outcome was the risk of developing dementia.
Results:
From a total of 90,396 and 85,906 patients with breast cancer and cataract, respectively, patients without behavior codes were excluded. Data for 15,407 breast cancer patients and 7,020 controls were analyzed before matching. After matching for comorbidities and age, either group comprised 2,252 patients. The median follow-up time was 104.1±24.0 months after matching. After matching, breast cancer was a predictor of a lower risk of for dementia (hazard ratio, 0.091; 95% confidence interval, 0.075 to 0.111; p < 0.001). In breast cancer patients, receiving chemotherapy and endocrine therapy did not significantly affect the incidence of dementia.
Conclusion
Breast cancer was associated with a remarkably decreased risk of dementia. The findings strongly suggest an inverse relationship between cancer and neurodegeneration, regardless of the adverse effects of cancer treatment on cognitive function.

BACKGROUND/AIMS: The different clinical manifestations of gastroesophageal reflux disease (GERD) may be influenced by associated psychological factors. We evaluated the psychological status (anxiety and depression) according to each subtype of GERD. METHODS: Subjects who underwent esophagogastroduodenoscopy and completed a symptom questionnaire between January 2008 and December 2011 were analyzed. The subjects were classified into the following groups: erosive reflux disease (ERD), non-erosive reflux disease (NERD), asymptomatic erosive esophagitis (AEE), and controls. Anxiety and depression were assessed using the State-Trait Anxiety Inventory and Beck Depression Inventory, respectively. RESULTS: We analyzed 19 099 subjects: 16 157 (84.6%), 176 (0.9%), 1398 (7.3%), and 1368 (7.2%) in the control, ERD, NERD, and AEE groups, respectively. Multiple multinomial logistic regression revealed a significant association of increased state (adjusted OR, 1.89; 95% CI, 1.53–2.33) and trait anxiety (adjusted OR, 1.78; 95% CI, 1.34–2.35) and depression (adjusted OR, 2.21; 95% CI, 1.75–2.80) with NERD. ERD group showed a significant association only with state anxiety (adjusted OR, 2.20; 95% CI, 1.27–3.81) and depression (adjusted OR, 2.23; 95% CI, 1.18–4.22). The AEE group, however, did not show any significant association with psychological factors. CONCLUSION: This cross-sectional study revealed that anxiety and depression levels were significantly higher in subjects with GERD (notably in the NERD) than in controls.

Background/Aims:
We investigated how interactions between humans and computer-aided detection (CADe) systems are influenced by the user’s experience and polyp characteristics.
Methods:
We developed a CADe system using YOLOv4, trained on 16,996 polyp images from 1,914 patients and 1,800 synthesized sessile serrated lesion (SSL) images. The performance of polyp detection with CADe assistance was evaluated using a computerized test module. Eighteen participants were grouped by colonoscopy experience (nurses, fellows, and experts). The value added by CADe based on the histopathology and detection difficulty of polyps were analyzed.
Results:
The area under the curve for CADe was 0.87 (95% confidence interval [CI], 0.83 to 0.91). CADe assistance increased overall polyp detection accuracy from 69.7% to 77.7% (odds ratio [OR], 1.88; 95% CI, 1.69 to 2.09). However, accuracy decreased when CADe inaccurately detected a polyp (OR, 0.72; 95% CI, 0.58 to 0.87). The impact of CADe assistance was most and least prominent in the nurses (OR, 1.97; 95% CI, 1.71 to 2.27) and the experts (OR, 1.42; 95% CI, 1.15 to 1.74), respectively. Participants demonstrated better sensitivity with CADe assistance, achieving 81.7% for adenomas and 92.4% for easy-to-detect polyps, surpassing the standalone CADe performance of 79.7% and 89.8%, respectively. For SSLs and difficult-to-detect polyps, participants' sensitivities with CADe assistance (66.5% and 71.5%, respectively) were below those of standalone CADe (81.1% and 74.4%). Compared to the other two groups (56.1% and 61.7%), the expert group showed sensitivity closest to that of standalone CADe in detecting SSLs (79.7% vs 81.1%, respectively).
Conclusions
CADe assistance boosts polyp detection significantly, but its effectiveness depends on the user’s experience, particularly for challenging lesions.
