Higher cumulative dose of topical corticosteroids is associated with osteoporosis and major osteoporotic fracture: A nationwide case-control study.

BACKGROUND: Connections between long-term use of topical corticosteroids (TCSs) of varying potency and osteoporosis and major osteoporotic fracture (MOF) are unclear. Susceptibility to adverse bone effects of TCSs in different sex, age and ethnic groups is unknown too. OBJECTIVES: To demonstrate the association between cumulative dose of TCSs of varying potency and osteoporosis and MOF in Taiwanese population, with stratified analysis of sex and age. METHODS: We conducted a nationwide case-control study and obtained data from Taiwan National Health Insurance Research Database. Cumulative TCS doses in different exposure periods were calculated, and the potency of TCSs was converted to prednisolone equivalent. Adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for osteoporosis and MOF associated with TCS use. RESULTS: From 2017 to 2020, 129,682 osteoporosis cases and 34,999 MOF cases were selected and randomly matched with 518,728 and 139,996 controls by sex and age. We found clear dose-response relationships between long-term TCS exposure and osteoporosis and MOF. For example, compared to no TCS use, adjusted ORs of osteoporosis were 1.216 (95% CI 1.189-1.243), 1.260 (95% CI, 1.241-1.280) and 1.341 (95% CI, 1.314-1.369) for exposure to low, medium and high cumulative TCS doses, respectively, over 5 years. Adjusted ORs of MOF were 1.118 (95% CI 1.069-1.170), 1.191 (95% CI, 1.156-1.227) and 1.288 (95% CI, 1.238-1.340) for exposure to low, medium and high cumulative TCS doses, respectively, over 5 years. Stratified analysis showed women had higher ORs of osteoporosis and MOF compared to men. Younger people (<50 years) had highest OR of osteoporosis compared to other age groups. CONCLUSIONS: Higher cumulative TCS dose was associated with increased risk of osteoporosis and MOF. Long-term use of TCSs should be cautious, especially in susceptible populations such as women and young people.

The impact of atopic dermatitis on health-related quality of life in Taiwan.

BACKGROUND/PURPOSE: Atopic dermatitis (AD) is a common skin disease. At present, there is little evidence regarding its impact on patients' health-related quality of life (HRQoL) in Taiwan. Therefore, this study investigated the relationship between AD severity and patients' HRQoL in Taiwan. METHODS: Patients with AD were recruited from three hospitals in Taiwan from April 2018 to April 2019. AD severity was measured using the Scoring of AD (SCORAD) scale, and HRQoL was assessed using the Dermatology Life Quality Index (DLQI) and the five-level version of EuroQol five-dimension questionnaire (EQ-5D-5L). RESULTS: A total of 200 patients (mean age: 34.4 years) were recruited, including 103 males and 97 females. They were further classified as 79 mild, 72 moderate, and 58 severe AD patients according to their SCORAD scores. There was a positive correlation between their SCORAD and DLQI scores (Spearman's r = 0.77, p < 0.001). Patients with severe AD had higher scores in all the DLQI questions, particularly the symptoms, feelings, and work/school. In addition, both the EQ-5D visual analogue scale (VAS) scores and utility index values were negatively correlated with the SCORAD scores (Spearman's r = -0.46 and -0.60, respectively, both p < 0.001). Patients with higher AD severity had more problems with mobility, usual activity, pain/discomfort, and anxiety/depression, while demographic characteristics did not significantly affect HRQoL. CONCLUSION: Higher AD severity is associated with poorer HRQoL in Taiwanese AD patients, with AD's effects on symptoms, feelings, and work/school being the most troublesome. Meanwhile, demographic factors did not affect HRQoL significantly.

Tenon excision with fibrin glue-assisted reattachment of conjunctiva flap (T.E.F.A.R.C) for the treatment of conjunctivochalasis.

To observe the surgical outcome of "Tenon Excision with Fibrin Glue-Assisted Reattachment of Conjunctiva Flap" (T.E.F.A.R.C.) for the treatment of symptomatic conjunctivochalasis (CCH). This is a retrospective case series of CCH patients undergoing T.E.F.A.R.C. from January 2017 to December 2020 were reviewed. Seven patients (14 eyes) with symptomatic CCH received T.E.F.A.R.C. in both eyes. The symptoms before and after the procedures were compared and surgical complication was evaluated. The mean follow-up time was 13.7 ± 2.14 months. After the operation, resolution of the symptoms was reported in 12 eyes (86%). The grade of CCH decreased from 3 to 0 in all 14 eyes, and the restoration of inferior conjunctival surface and fornix within 1 day was also observed in all eyes. Most patients had localized injection and mild chemosis after the operation, which mostly recovered within 3 weeks. No complication or recurrence of CCH was reported after 1 year of follow-up. In conclusion, T.E.F.A.R.C. is a simple and effective treatment option for CCH with less surgical complication. Future larger studies are needed to confirm its clinical applicability.

Comparing the results of manual and automated quantitative corneal neuroanalysing modules for beginners.

This study aimed to evaluate the reliability of in vivo confocal microscopic neuroanalysis by beginners using manual and automated modules. Images of sub-basal corneal nerve plexus (SCNP) from 108 images of 18 healthy participants were analyzed by 7 beginner observers using manual (CCMetrics, [CCM]) and automated (ACCMetrics, [ACCM]) module. SCNP parameters analyzed included corneal nerve fiber density (NFD), corneal nerve branch density (NBD), corneal nerve fiber length (NFL), and tortuosity coefficient (TC). The intra-observer repeatability, inter-observer reliability, inter-module agreement, and left-right eye symmetry level of SCNP parameters were examined. All observers showed good intra-observer repeatability using CCM (intraclass correlation coefficient [ICC] > 0.60 for all), except when measuring TC. Two observers demonstrated especially excellent repeatability in analyzing NFD, NBD, and NFL using manual mode, indicating the quality of interpretation may still be observer-dependent. Among all SCNP parameters, NFL had the best inter-observer reliability (Spearman's rank-sum correlation coefficient [SpCC] and ICC > 0.85 for the 3 original observers) and left-right symmetry level (SpCC and ICC > 0.60). In the additional analysis of inter-observer reliability using results by all 7 observers, only NFL showed good inter-observer reliability (ICC = 0.79). Compared with CCM measurements, values of ACCM measurements were significantly lower, implying a poor inter-module agreement. Our result suggested that performance of quantitative corneal neuroanalysis by beginners maybe acceptable, with NFL being the most reliable parameter, and automated method cannot fully replace manual work.
