Indocyanine green fluorescence visualizes landmark arteries for endoscopic sinus and skull base surgery.

Objective: Landmark arteries during endoscopic sinus surgery are currently identified on the basis of anatomy, CT imaging and navigation, and Doppler flowmetry. However, the advantage of intraoperative fluorescence imaging during endoscopic sinus surgery has not been demonstrated. This study aimed to investigate whether Indocyanine Green (ICG) is useful for visualizing landmark arteries during endoscopic sinus and skull base surgery.

[Diagnostic efficacy and pitfalls of a 64-raw multislice computed tomography scan for mild head injuries in children].

The aim of this study is to analyze the usefulness of 64-raw multislice computed tomography (CT) scans and bone images of three-dimensional CT (3D-CT) scans for evaluation of mild head injuries in children. Thirteen children (9 boys and 4 girls, less than or equal to 15 years old) with mild head injury were included in the study. Head CT scans obtained within 24 hours after injury.

High expression of L-type amino acid transporter 1 in infiltrating glioma cells.

L-type amino acid transporter 1 (LAT1), a neutral amino acid transport agent, is essential for the transport of large neutral amino acids. LAT1 also corresponds to tumor-associated gene-1 (TA1), an oncofetal antigen that is expressed primarily in fetal tissues and cancer cells such as glioma cells. We have investigated the expression of the transporter in the human primary glioma tissue from 68 patients.

[A case of bleeding dural arteriovenous fistula of the transverse-sigmoid sinus with pure leptomeningeal drainage, varix: case report].

We reported a case of bleeding from the varix of a transverse-sigmoid sinus dural arteriovenous fistula with pure leptomeningeal drainage. A 55-year-old man presented with visual disturbance. neurological examination revealed left homonymous hemianopsia.

[The improvement in regional cerebral blood flow in the anterior cranial fossa which was affected by a dural arteriovenous fistula: case report].

We report a case of dural arteriovenous fistula of the anterior cranial fossa with venous ischemia. A 55-year-old man presented with headache and visual disturbance. Neurological examination showed no abnormality.

[Postoperative subdural empyema due to Propionibacterium acnes].

Propionibacterium acnes are gram-positive pleomorphic rods that grow under an anaerobic condition. They are the most frequent inhabitants of sebaceous glands of skin, hair follicles, mouth, upper respiratory tract, and as a frequent contaminant in laboratory cultures. Propionibacterium acnes is an underestimated but significant cause of postneurosurgical infection, especially in the presence of foreign bodies such as shunt systems.
