A new technique for establishing ultrasound-guided central access involves the use of the axillary vein, the distal projection of the subclavian vein, via the lateral chest. ⋯ The Valsalva maneuver and Trendelenburg angles above 10° do not increase axillary vein area but do increase patient discomfort. Our data suggest optimal positioning in the supine resting position or at a 5° Trendelenburg position.

Thyrotoxic periodic paralysis is rare in Caucasian populations, but affects approximately 2% of East Asians with thyrotoxicosis (13% of males, 0.17% of females). The presentation is characterized by abrupt-onset hypokalemia and profound proximal muscular weakness, and commonly occurs after carbohydrate loading or exercise. ⋯ It may be important to check thyroid function in patients presenting with acute paralysis, especially those of Asian origin. In patients with thyrotoxic periodic paralysis, administration of potassium, with cardiac monitoring and a total dose of <50 mmol, limits the dysrhythmia risk. Patients are likely to benefit from the prescription of non-selective beta-blockers until they become euthyroid. In contrast to familial periodic paralysis, regular oral potassium supplementation is ineffective in thyrotoxic periodic paralysis, and acetazolamide precipitates, rather than prevents, attacks.

Knives cause more disabling injuries than any other type of hand tool. ⋯ Knives represent an important source of morbidity and mortality to people of all ages. Manufacturers should develop safer knife designs that incorporate features, such as improved opening and closing mechanisms on pocket knives, to prevent these injuries. Other potential safety efforts include targeted educational interventions and changes in voluntary product safety standards and public policy.

Ovarian torsion (OT) is one of the most common gynecologic surgical emergencies. All age groups can be affected, but ovarian stimulation, as found during early pregnancy or infertility treatment, is a major risk factor. ⋯ Ovarian torsion in pregnancy is increasing in frequency due to the growing prevalence of ovarian stimulation treatment. Although diagnostic ultrasound is a frequently used imaging tool in patients with suspected OT, the mere presence of blood flow on Doppler ultrasonography of the adnexa has a poor negative predictive value. A high clinical suspicion and early laparoscopic management correlate with favorable maternal and fetal outcomes.

Emergency Department (ED) overcrowding and ensuing concern about patients who leave without treatment have become a mounting national concern. In addition, the Centers for Medicaid and Medicare Services released regulatory standards for EDs requiring reporting of time from initial triage to decision to admit, as well as actual time of admission. ⋯ Our study demonstrated that a tailored ED redesign process can dramatically decrease the time to provider, ALOS, and LWOT rates.
