Hyperglycemic state frequently presents with neurologic manifestations including choreoathetosis, ballismus, dysphagia, seizures, and coma. Also, hyperglycemic hemianopia has been rarely reported to cause temporary damage to the visual cortex, resulting in homonymous hemianopia. A 65-year-old man was admitted because of right homonymous hemianopia accompanied by hyperglycemia. Brain single-photon emission computed tomography showed focal hyperperfusion in the left occipital lobe. Herein we report a case of reversible homonymous hemianopia with cerebral hyperperfusion associated hyperglycemia without seizure.

Continuous renal replacement therapy (CRRT) has become the standard modality of renal replacement therapy (RRT) in critically ill patients. However, consensus is lacking regarding the criteria for discontinuing CRRT. Here we validated the usefulness of the prediction model for successful discontinuation of CRRT in a multicenter retrospective cohort. Methods: One temporal cohort and four external cohorts included 1,517 patients with acute kidney injury who underwent CRRT for >2 days from 2018 to 2020. The model was composed of four variables: urine output, blood urea nitrogen, serum potassium, and mean arterial pressure. Successful discontinuation of CRRT was defined as the absence of an RRT requirement for 7 days thereafter. Results: The area under the receiver operating characteristic curve (AUROC) was 0.74 (95% confidence interval, 0.71–0.76). The probabilities of successful discontinuation were approximately 17%, 35%, and 70% in the low-score, intermediate-score, and highscore groups, respectively. The model performance was good in four cohorts (AUROC, 0.73–0.75) but poor in one cohort (AUROC, 0.56). In one cohort with poor performance, attending physicians primarily controlled CRRT prescription and discontinuation, while in the other four cohorts, nephrologists determined all important steps in CRRT operation, including screening for CRRT discontinuation. Conclusion: The overall performance of our prediction model using four simple variables for successful discontinuation of CRRT was good, except for one cohort where nephrologists did not actively engage in CRRT operation. These results suggest the need for active engagement of nephrologists and protocolized management for CRRT discontinuation.

Background/Aims: The occurrence of gout attacks at the start of uric acid lowering treatment worsens compliance. We aimed to determine the appropriate dose of febuxostat to reduce the occurrence of gout attacks during the initial treatment period. Methods: We retrospectively analyzed the data of patients diagnosed with gout who underwent treatment at Jeju National University Hospital between May 2018 and May 2020. Results: Two-hundred and twenty-seven patients were included, with a mean age of 53.2 ± 16.4 years, and 219 (96.5%) were male. The patients were divided into two groups according to the starting dose of febuxostat (20 mg vs. 40 mg). There were no significant differences in mean age, disease duration, colchicine, estimated glomerular filtration rate (eGFR), initial uric acid levels, and presence of subcutaneous tophi between the two groups. Gout attacks occurred more frequently in the 20 mg group than in the 40 mg group during the first 3 months of treatment (32.0% vs. 14.3%, p = 0.002), particularly during the first month (21.3% vs. 7.5%, p = 0.005). Multivariate logistic regression analysis was conducted adjusting for the effects of disease duration, the presence of subcutaneous tophi, eGFR, and initial uric acid levels. A febuxostat starting dose of 40 mg (odds ratio, 0.464; 95% confidence interval [CI], 0.246 to 0.862; p = 0.015) and anti-inflammatory prophylaxis (odds ratio, 0.359; 95% CI, 0.158 to 0.813; p = 0.014) were found to be independent factors associated with a gout attack. Conclusions Starting uric acid lowering treatment with febuxostat 40 mg rather than 20 mg may reduce the incidence of gout attacks in the early period of treatment in Korean patients with gout.

Background: This study was conducted to identify the association between sleep duration and suicidal ideation among farmers in Korea. Methods: We used Safety for Agricultural Injuries of Farmers cohort data collected from September 2015 to June 2018, which was an agricultural survey on the health and behaviors of adult farmers in Jeju island, Korea. Results: A total of 964 participants were included in the analysis, and 3.7% of them were identified with having suicidal ideation. The frequencies of average daily sleep duration of <6 h (short sleep), 6–8 h (normal sleep), and >8 h (long sleep) were 24.4%, 70%, and 5.6%, respectively. Multivariate analyses revealed that short sleep duration was significantly associated with suicidal ideation compared with normal sleep duration (odds ratio = 2.49, 95% confidence interval = 1.07–5.77). Conclusion Our findings suggest that short sleep duration in farmers result in higher suicidal ideation. Because individuals who have suicidal ideation often commit suicide, careful monitoring is required to prevent suicide in farmers with short sleep duration.

Background: We aimed to investigate the prevalence of low back pain (LBP) and its associated agricultural work-related, biomechanical factors among this population. Methods: We analyzed initial survey data from the Safety for Agricultural Injury of Farmers cohort study involving adult farmers in Jeju Island. The prevalence of LBP was calculated with associated factors. Results: In total, 1,209 participants were included in the analysis. The overall prevalence of LBP was 23.7%. Significant associations for LBP were the type of farming activity, length of farming career, prior agricultural injury within 1 year, and stress levels. Multivariate logistic regression analysis revealed three biomechanical factors significantly related to LBP: repetitive use of particular body parts; the inappropriate posture of the lower back and neck. Conclusions Some occupational, and biomechanical risk factors contribute to LBP. Therefore, postural education, injury prevention education, and psychological support will be needed to prevent LBP.

Milwaukee shoulder syndrome (MSS) is a rare disease in which joints are destroyed and occurs mainly in elderly women. We describe rapidly progressive MSS with complete destruction of the shoulder joint within 2 months. An 80-year-old woman visited the outpatient clinic with shoulder pain for 2 weeks. rotator cuff tear arthropathy was diagnosed, and nonsteroidal anti-inflammatory drugs were prescribed. Two months later, her shoulder pain worsened without trauma. Shoulder swelling and tenderness, and arm lifting inability were observed. Complete humeral head disruption was observed by radiography. We diagnosed MSS based on the presence of serohematic and noninflammatory joint effusion, periarticular calcific deposits, and rapid joint destruction, and initiated conservative treatment. When initially treating elderly patients with shoulder arthropathy, it is advisable to perform short-term follow-up and to consider the possibility of crystal-induced arthropathy.
