We investigated the ability of echo-planar imaging with L1-regularized iterative sensitivity encoding-based diffusion-weighted imaging (DWI) to improve the image quality and reduce the scanning time in prostate magnetic resonance imaging. We retrospectively analyzed 109 cases of prostate magnetic resonance imaging. We compared variables in the quantitative and qualitative assessments among 3 imaging groups: conventional parallel imaging-based DWI (PI-DWI) with an acquisition time of 3 minutes 15 seconds; echo-planar imaging with L1-regularized iterative sensitivity encoding-based DWI (L1-DWI) with a normal acquisition time (L1-DWINEX12) of 3 minutes 15 seconds; and L1-DWI with a half acquisition time (L1-DWINEX6) of 1 minute 45 seconds. ⋯ In the qualitative analysis, the image quality score for L1-DWINEX12 was significantly higher than those of PI-DWI and L1-DWINEX6. A non-inferiority assessment demonstrated that L1-DWINEX6 was non-inferior to PI-DWI in terms of both quantitative CNR-DWI and qualitative grading of image quality with a <20% inferior margin. L1-DWI successfully demonstrated a reduced scanning time while maintaining good image quality.

Case Reports
CT findings of glycogen storage disease I complicated with pancreatitis: A case report.
The incidence of glycogen storage disease type I (GSD I) in the overall population is 1/100,000.[1] Hyperlipidemia in patients with GSD I can induce pancreatitis. Three cases of GSD I complicated with pancreatitis have been reported.[2] Here, the computed tomography (CT) features of GSD I complicated with pancreatitis are reported for the first time. ⋯ The density of the liver depends on the relative amount of glycogen and fat, which can be increased, normal, or decreased. Hyperlipidemia in patients with GSD I can induce pancreatitis.

Tethered cord syndrome (TCS) represents a spectrum of neurological symptoms that are caused by constant or intermittent axial traction of the terminal cone of the spinal cord due to abnormal positioning. It is uncommon for abnormal structures of TCS to be accompanied by split cord malformation, thoracic spinal stenosis, and other spinal cord diseases. ⋯ This is a rare case of TCS combined with thoracic disc herniation and bony mediastinum. A more conservative invasive surgical approach was elected and markedly improved the patient's symptoms. Additional clinical cases are needed to confirm the stability and feasibility of this surgical approach.

Myelodysplastic Syndrome (MDS) is a common blood dyscrasia that mainly affects the elderly population. Several prognostic scores are available utilizing blood count variables and cytogenetic abnormalities, targeting the disease rather than the patient. Sarcopenia and frailty are associated with shortened survival rates in various disease states. ⋯ Low ALT levels were associated with increased mortality among patients with MDS. Impact: Using ALT as a frailty metric may allow patient-centered, personalized care in this patient population. A low ALT level reflects the pre-morbid robustness of patients and is not intended to replace disease-centered characteristics.

Surgical treatment for patients with Parkinson disease (PD) under general anesthesia has become frequent. PD is a significant predictor of postoperative complications. However, the factors that predict complications in patients with PD remain unknown. ⋯ The operation time, the red blood cell transfusion and the rate of rotigotine usage were higher in patients with complications than those without (314 ± 197 min vs 173 ± 145 min, P = .006; 0 [0-560] mL vs 0 [0-0] mL, P = .02; 39% vs 6%, P = .003, respectively) (mean ± standard deviation or median [interquartile range]). Preoperative rotigotine usage (OR: 9.33; 95% confidential interval [CI]: 2.07-42.07; P = .004) was an independent risk factors for postoperative complications. The findings indicate that clinicians should closely monitor postoperative complications when patients with PD who have received transdermal dopamine agonists undergone longer time surgery.
