A case of corneal opacity caused by atovaquone administration.

Purpose: Atovaquone is an alternative drug that is used for the prevention and treatment of pneumonia when the first-line drug, sulfamethoxazole-trimethoprim (ST combination), cannot be used due to side effects. However, atovaquone is known to cause ocular side effects including oculomucocutaneous syndrome and vortex keratopathy. In this report, we describe a patient who developed bilateral white granular diffuse corneal opacity that extended from the corneal sub-epithelium to the stroma after continuous oral atovaquone administration for 14 months.

The Risk of Intravenous Cement Leakage and Short-term Outcomes of Selective Cement-augmented Pedicle Screws: A Multicenter Retrospective Study.

Study Design: Multicenter retrospective cohort study.

Objective: To evaluate the efficacy and safety of using cement-augmented pedicle screw (CAPS) fixation only for the cephalad and caudal vertebral bodies.

Summary Of Background Data: Pedicle screw fixation is less effective in patients with low-quality bone.

stana: an R package for metagenotyping analysis and interactive application based on clinical data.

Metagenotyping of metagenomic data has recently attracted increasing attention as it resolves intraspecies diversity by identifying single nucleotide variants. Furthermore, gene copy number analysis within species provides a deeper understanding of metabolic functions in microbial communities. However, a platform for examining metagenotyping results based on relevant grouping data is lacking.

Bilateral Fuchs' Superficial Marginal Keratitis Diagnosis and Treatment.

In this study, we reported two patients with clinical pictures compatible with the diagnosis of bilateral Fuchs' superficial marginal keratitis (FSMK) treated with surgical treatment and anti-inflammatory drugs. The cases suffered from bilateral photophopia, blurred vision, and pseudopterygium with normal intraocular pressure (IOP). Pseudopterygia extended from temporal and nasal sides and had a gray line between the corneal normal epithelium with no lipid deposits.
