Corynebacterium striatum (C. striatum ) is an aerobic Gram-positive rod, which is an organism of the respiratory tract and skin. Because of its low virulence, it is usually thought to be a contaminant even if it is shown in culture tests, but it can cause endocarditis and respiratory infections, and rarely meningitis and arthritis. Infection with C. striatum has been reported in patients with reduced immunity, as well as in patients with catheter or broken skin barriers. Septic knee arthritis caused by C. striatum infection is rarely reported, and knee joint infection by C. striatum in patients who underwent arthroscopic debridement for previous septic arthritis is even more rare. Therefore, we report a case of septic knee arthritis caused by C. striatum that was improved by early diagnosis and arthroscopic treatment.

Background: This study aims to compare the clinical outcomes of steroid injections during the rehabilitation period after arthroscopic rotator cuff repair (ACRC). Methods: Among patients who underwent ARCR, 117 patients who met the inclusion and exclusion criteria were enrolled. Pain and rangeof motion (ROM) recovery at the 3-, 6-, and 24-month follow-up visits and functional outcome at the 24-month follow-up were comparedbetween 45 patients who received ultrasound-guided subacromial steroid injection at postoperative week 4 or 6 and 72 patients who didnot. Functional outcome was assessed using the American Shoulder and Elbow Surgeons (ASES) score and Constant score. Healing of therepaired tendon and retear were observed at the 6-month follow-up via magnetic resonance imaging (MRI) or computed tomography (CT)arthrography. Results: At the 3-month follow-up, the steroid injection group showed lower visual analog scale scores than the control group (p<0.05) andshowed faster recovery of forward flexion and internal rotation (p<0.05). From the 6-month follow-up, the two groups did not show differences in pain and ROM, and the ASES score and Constant score also did not significantly differ at the 24-month follow-up. The two groupsdid not differ in retear rate as determined by MRI or CT arthrography at the 6-month follow-up. Conclusions This study demonstrated that ultrasound-guided subacromial steroid injection at 4 or 6 weeks after ARCR leads to quick painreduction and ROM recovery until 3 months after surgery. Therefore, subacromial steroid injection is speculated to be an effective and relatively safe method to assist rehabilitation.

OBJECTIVE: To investigate the immediate effect of dorsal penile nerve (DPN) stimulation on detrusor pressure (Pdet) and blood pressure (BP) during hyper-reflexic contractions of the bladder in patients with cervical spinal cord injury (SCI). METHOD: The subjects were eight male patients with cervical SCI who had symptoms of autonomic dysreflexia. During water-cystometry, BP was monitored using an intra-arterial catheter into the radial artery, and was recorded simultaneously with the Pdet. Electrical stimulation was applied to the DPN, using surface electrodes each time a bladder contraction was detected. Baseline BP and BP at the first and the last hyper-reflexic contractions of bladder were measured with Pdet, respectively. RESULTS: As Pdet increased, the BP increased in all cases. The reflex contractions of the bladder were effectively suppressed by DPN stimulation, and as the Pdet decreased during stimulation, radial arterial pressure also decreased immediately and significantly. CONCLUSION: DPN stimulation can lower both Pdet and the elevated BP.
