Real-world management and long-term outcomes of diabetic macular oedema with good visual acuity.

Purpose: To evaluate the management and long-term outcomes of patients with diabetic macular oedema (DMO) and good initial visual acuity in real-world settings.

Methods: We reviewed 122 eyes of 100 patients with treatment-naive DMO and initial best-corrected visual acuity (BCVA) of 20/25 or better. We assessed clinical characteristics, logMAR BCVA, central subfield thickness (CST), cumulative intravitreal injections and laser treatments at yearly intervals, and characteristics at time of initial treatment. Linear mixed effects models were used to identify predictors of visual outcomes.

Results: At presentation, mean BCVA was 0.057 ± 0.048 logMAR (Snellen 20/23) and mean CST was 288 ± 57 μm. After a median follow-up of 3 years, 51% of eyes underwent treatment. More eyes underwent intravitreal injection as initial treatment (54%), but lasers were initiated at an earlier time and at better BCVA. Final BCVA was associated with better BCVA (P < 0.001) and earlier timing (P = 0.017) at initial treatment, but not CST at first treatment (P = 0.634) or cumulative number of injections or lasers (P = 0.441-0.606).

Conclusion: DMO with good initial visual acuity should be monitored closely, as delay in treatment initiation is associated with worse visual outcomes. BCVA at time of initial treatment is the strongest determinant of final visual acuity.

Both Ultrasound Features and Nuclear Atypia are Associated with Malignancy in Thyroid Nodules with Atypia of Undetermined Significance.

Ann Surg Oncol 2018 Dec 9;25(13):3913-3918. Epub 2018 Oct 9.

Department of Surgery, University of California, Davis Medical Center, Sacramento, CA, USA.

Background: The optimal management of thyroid nodules that undergo fine-needle aspiration (FNA) with findings of atypia of undetermined significance (AUS) is unclear. Categorizing nodules by AUS subtype and ultrasound characteristics may improve risk stratification. Therefore, the purpose of this study is to evaluate the association between AUS subtype and ultrasound features on risk of malignancy (ROM).

Methods: We performed a review of all patients with a thyroid nodule who underwent an FNA at our institution between January 2010 and November 2015. Patients with AUS were divided into groups with (1) nuclear atypia, (2) architectural atypia, or (3) Hurthle cell atypia. Their ultrasound features were assessed using the American Thyroid Association (ATA) thyroid nodule sonographic patterns. We conducted a univariate and multivariable analysis to determine the association between AUS subtype and other variables of interest with ROM.

Results: Of the 3428 thyroid nodules that underwent FNA, 237 (6.9%) had AUS. Of the 97 surgically resected nodules, 67 (69%) were benign and 30 (31%) were malignant. On univariate analysis nuclear atypia (p < 0.01) was associated with a thyroid malignancy. On multivariable analysis, both ATA high-risk ultrasound features (p = 0.04, odds ratio [OR] 3.68) and nuclear atypia (p < 0.01, OR 11.8) were independently associated with a final diagnosis of thyroid carcinoma.

Conclusions: Nuclear atypia and ATA high-risk ultrasound features are useful in identifying patients with AUS that are at a higher risk of thyroid malignancy. Surgeons should take these factors into consideration when evaluating patients with AUS.
