Orbital Apex Syndrome with Nasal Type Natural Killer(NK)/T-cell Lymphoma of Sphenoid and Ethmoid Sinus

PURPOSE: To report a case of nasal-type NK/T cell lymphoma occurring in the sphenoid and ethmoid sinuses of an orbital apex syndrome patient. CASE SUMMARY: A 61-year-old male patient visited our hospital for the impairment of vision in the right eye for the previous month, and for right-side blepharoptosis, pain around the eyeball, and limitation of extraocular movement in the right eye for three days earlier. In MRI (magnetic resonance image) and CT (computed tomography), shades with vague boundaries were observed in the right sphenoid and ethmoid sinuses, and open biopsy and decompression were performed for the lesions. After the surgery, the vision of the right eye increased, and improvement was observed in the right blepharoptosis, the pain around the eyeball, and in the limitation of motility of the extraocular muscle in the right eye. The patient was diagnosed with nasal type NK/T cell lymphoma in biopsy, and radiotherapy and chemotherapy were performed.

The Possibility of Fluid Contamination Within Syringes in Case of Experimental Needle Contamination

PURPOSE: The present study examined the risk of intraocular infection only in cases where the injection needle was replaced when the injection needle was contaminated before intraocular injection. METHODS: Staphylococcus aureus and Staphylococcus epidermidis were cultured and smeared on the end of 30 syringe needles containing 0.1 mL normal saline. After removing only the injection needle, the normal saline in the syringes was injected onto blood agar plates and cultured. RESULTS: The culture results were positive in 21 out of 30 samples in the group smeared with Staphylococcus aureus, and in 25 out of 30 samples in the group smeared with Staphylococcus epidermidis. CONCLUSIONS: When the injection needle is contaminated, the replacement of the needle does not eliminate the possibility of intraocular infection.
