Unilateral chronic angle-closure glaucoma in a pediatric patient with neurofibromatosis: a case report

Neurofibromatosis type 1 (NF1) is an autosomal dominant genetic disease that causes multi-system damage. It is rarely associated with angle-closure glaucoma, especially in pediatric patients. We herein report a case of unilateral chronic angle-closure glaucoma in a patient with NF1. A 5-year-old girl with a large subcutaneous soft mass and multiple scattered coffee-milk spots presented with low vision, increased intraocular pressure, and angle closure in her right eye. Lisch nodules were seen in both eyes. In her right eye, ectropion uveae was observed at the top and bottom margins of the pupil. Magnetic resonance imaging of the skull and orbit revealed no abnormalities. Finally, trabeculectomy was performed on the right eye, after which the right eye showed a stable intraocular pressure. NF1 combined with angle-closure glaucoma is rare and easily missed in the clinical setting. Early diagnosis and treatment may achieve good results

Dataset of tensile strength development of concrete with manufactured sand

This article presents 755 groups splitting tensile strength tests data of concrete with manufactured sand (MSC) in different curing age ranged from 1 day to 388 days related to the research article “Experimental study on tensile strength development of concrete with manufactured sand” (Zhao et al., 2017) [1]. These data were used to evaluate the precision of the prediction formulas of tensile strength of MSC, and can be applied as dataset for further studies
