Objectives: To evaluate central foveal thickness (CFT) variability and accompanying changes in visual acuity (VA) 12 months before and after treatment with the 190 mcg fluocinolone acetonide (FAc) intravitreal implant for diabetic macular edema (DME). Methods: The Iluvien Clinical Evidence cohort study in the United Kingdom (ICE-UK) investigated the effectiveness of the FAc implant in people treated at 13 hospitals from April 2013 to April 2015. The following parameters were calculated for CFT for each patient: mean, standard deviation (SD), retinal thickness amplitude (RTA, the difference between maximum and minimum values), and coefficient of variation (CV). ⋯ Conclusions: After accounting for the reduction in CFT, retinal thickness stabilized following FAc implantation. There might be VA benefits in reducing variability in CFT over time. This merits further exploration but would require more frequent CFT observations in order to properly determine patterns of retinal thickness variability.

Objective: Hypoactive sexual desire disorder (HSDD) in women has been viewed inaccurately by some in the medical and payer community as analogous to erectile dysfunction (ED) in men. This literature review aims to highlight the distinctions between HSDD and ED. Methods: Two systematic literature searches were conducted on the epidemiology, symptomatology and biopsychosocial outcomes of HSDD and ED. ⋯ ED is measured by objective, physiological responses (erection and sexual function), but quantitative assessments for HSDD are more difficult because loss of desire with associated distress has to be assessed. Outcome measures used to assess ED, such as the number of satisfying sexual events, are far less informative as an endpoint for randomized clinical trials of treatments for HSDD. Conclusions: HSDD and ED are distinct conditions affecting different phases of the sexual response model, and thus require clear and unique clinical characterization and adequate communication between the health care professional and patient for appropriate diagnosis, management and treatment.

Objective: This economic evaluation aims to provide a preliminary assessment of the cost-effectiveness of radiofrequency ablation (RFA) compared with argon plasma coagulation (APC) when used to treat APC-refractory gastric antral vascular ectasia (GAVE) in symptomatic patients. Methods: A Markov model was constructed to undertake a cost-utility analysis for adults with persistent symptoms secondary to GAVE refractory to first line endoscopic therapy. The economic evaluation was conducted from a UK NHS and personal social services (PSS) perspective, with a 20-year time horizon, comparing RFA with APC. ⋯ The model estimated that implementing RFA would result in reductions in the need for intravenous iron, endoscopic intervention and requirement for blood transfusions by 27.1%, 32.3% and 36.5% respectively. Compared to APC, RFA was associated with an estimated 36.7% fewer procedures. Conclusions: RFA treatment is likely to be cost-effective for patients with ongoing symptoms following failure of first line therapy with APC and could lead to substantive reductions in health care resource.

Objective: The study aims to evaluate how asthma influences on clinical symptoms, imaging scores and HRQL in CRS patients. Methods: The study enrolled CRS patients and collected data about asthma status, clinical symptoms, allergic sensitization, computed tomography (CT) and 22-item SinoNasal Outcome questionnaire (SNOT-22). Matching pairs of asthmatic and non-asthmatic CRS patients were defined based on age, gender and nasal polyp presence. ⋯ Although there was no difference in Lund-Mackay score, there was a slightly higher osteitis score in CRS asthma group (5.21 vs. 3.45; p = .059). Conclusion: CRS patients with asthma have significantly worse impairment of smell and taste when compared to non-asthmatic CRS patients. This is the only significant difference which is independent of nasal polyp presence, gender, age and allergy.
