Status of Single Nucleotide Polymorphism of Matrix Gla Protein Gene (rs4236) in Nephrolithiasis: A Preliminary Study in Indian Population.

Background: Urine is a supersaturated solution with solutes in very high concentration. Matrix gla protein (MGP) is one of the proteins involved in inhibition of extracellular calcification. Among the various polymorphisms studied, polymorphism of SNP rs4236 in the MGP gene is found to have association with nephrolithiasis.

Postoperative Mycobacterium abscessus nodular conjunctivitis.

Non-tuberculous or 'atypical' mycobacteria are unusual causes of ocular or periocular infection. We report a case of postoperative Mycobacterium abscessus infection of the conjunctiva. A 71-year-old gentleman developed nodular conjunctival injection and irritation 6 weeks after cataract surgery.
