A 48-year-old man with long-standing type 2 diabetes mellitus (recent glycated hemoglobin level, 6.5%) and chronic kidney disease (baseline creatinine level, 3.3 mg per deciliter [292 μmol per liter]; glomerular filtration rate, 24 ml per minute per 1.73 m2 of body-surface area) presented to his primary care physician with a 3-month history of numbness, tingling, and faint violaceous discoloration of the tips of multiple fingers and toes. His physical examination showed reduced light-touch sensation in a glove-and-stocking distribution; the radial and pedal pulses were palpable. The vitamin B12 level was 260 pg per milliliter (192 pmol per liter; normal range, 190 to 950 pg per milliliter [140 to 701 pmol per liter]). ⋯ One month later, a nontraumatic wound developed on the left foot. The ankle–brachial index (ABI) was 1.2 on both sides (normal range, 0.91 to 1.3). Wound care was initiated for a presumed neuropathic ulcer.

Multicenter Study
Encephalitis in travellers: A prospective multicentre study.
As the epidemiology of encephalitis varies from one country to another, international travel may be an important clue for the diagnostic workout of this puzzling disease. ⋯ The two primary causes of encephalitis in travellers are arboviruses and HSV. Empirical treatment of encephalitis in travellers must include acyclovir. Pre-travel advice and vaccination may decrease the risk of encephalitis in travellers.

Randomized Controlled Trial Multicenter Study
Treat-to-Target or High-Intensity Statin in Patients With Coronary Artery Disease: A Randomized Clinical Trial.
In patients with coronary artery disease, some guidelines recommend initial statin treatment with high-intensity statins to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). An alternative approach is to begin with moderate-intensity statins and titrate to a specific LDL-C goal. These alternatives have not been compared head-to-head in a clinical trial involving patients with known coronary artery disease. ⋯ Among patients with coronary artery disease, a treat-to-target LDL-C strategy of 50 to 70 mg/dL as the goal was noninferior to a high-intensity statin therapy for the 3-year composite of death, myocardial infarction, stroke, or coronary revascularization. These findings provide additional evidence supporting the suitability of a treat-to-target strategy that may allow a tailored approach with consideration for individual variability in drug response to statin therapy.

Parathyroid adenoma is the most frequent cause of primary hyperparathyroidism. In recent years, the preoperative location of parathyroid adenomas allowed minimally invasive surgical techniques that have become preferred over the traditional bilateral neck exploration. The more recent guidelines on this subject highlight the role of nuclear medicine imaging tests. The aim of this study was to review the current role of Doppler ultrasound (US) in assessing the preoperative location of parathyroid adenomas in patients with primary hyperparathyroidism. ⋯ Doppler ultrasound showed high diagnostic accuracy even in patients with nodular thyroid disease regardless of calcium and parathyroid hormone levels and adenoma size. Furthermore, its safety, affordability and availability should favor its use as first line test in primary hyperparathyroidism to assess the preoperative location of parathyroid adenomas.
