Disruption of tear-film homeostasis (altered composition, reduced production, rapid evaporation) and resulting ocular surface inflammation cause the discomfort and blurred vision of dry eye disease. Many cases are caused by tear evaporation due to meibomian gland dysfunction. Other precipitating factors can include lacrimal gland dysfunction, poor eyelid function, environmental factors, extended screen time, inflammatory conditions such as Sjögren's syndrome, and use of some ocular or systemic drugs such as antihistamines, retinoids, or selective serotonin reuptake inhibitors...

Onychomycosis is caused most commonly by Trichophyton rubrum or T. mentagrophytes. About 10% of all persons worldwide and 40% of those ≥60 years old are believed to have the disease. Risk factors include older age, diabetes, poor peripheral circulation, smoking, HIV infection, psoriasis, and immunosuppression. Left untreated, onychomycosis can cause nail plate destruction, ingrown nails, and (particularly in patients with diabetes) secondary infections. Guidelines on treatment of onychomycosis have been published.
