Programmable Valve With Virtual off Function Is Useful for Chronic Subdural Hematoma After Ventriculoperitoneal Shunt Surgery.

Over-drainage after a ventriculoperitoneal (VP) shunt can often lead to chronic subdural hematoma; however, the treatment is unclear. Hematoma drainage is performed after physically stopping the shunt function, such as by ligating or removing the shunt system. However, shunt reconstruction is required after the subdural hematoma improves.

Association of diabetic retinopathy with kidney disease progression according to baseline kidney function and albuminuria status in individuals with type 2 diabetes.

Background: Whether diabetic retinopathy (DR) can predict kidney disease progression in individuals with diabetes remains unclear. Furthermore, there are only a limited number of studies investigating the association between DR and kidney outcomes classified according to baseline kidney function and albuminuria status. Here, we examined the association of DR with kidney disease progression in individuals with type 2 diabetes.

Effects of ambient atmospheric pressure on intraocular pressure measured using a Goldman applanation tonometer in normal eyes under ordinary conditions.

Purpose: Little is known about the effects of ambient atmospheric pressure (AP) on intraocular pressure (IOP) under ordinary conditions. This study aimed to investigate the effects of AP on Goldmann applanation tonometer-measured IOP (GAT-IOP) in normal eyes under everyday atmospheric conditions adjusting for effects of possible confounding factors including other climatic factors.

Methods: Data obtained from 2,431 normal healthy eyes of 2,431 subjects (mean age: 56.
