Luteoma of pregnancy masquerading as a granulosa cell tumor.

Pregnancy luteomas are rare, nonmalignant lesions thought to be caused by hormonal changes during pregnancy. Granulosa cell tumor is a rare type of ovarian cancer; 10% occur during pregnancy and typically present with elevated inhibin levels. Herein, we present a case of a pregnant female with a pelvic mass and elevated inhibin B suggestive of a granulosa cell tumor, yet with final pathology consistent with a pregnancy luteoma.

Reducing time-to-unit among patients referred to an outpatient stroke assessment unit with a novel triage process: a prospective cohort study.

Background: To evaluate the performance of a novel triage system for Transient Ischemic Attack (TIA) units built upon an existent clinical prediction rule (CPR) to reduce time to unit arrival, relative to the time of symptom onset, for true TIA and minor stroke patients. Differentiating between true and false TIA/minor stroke cases (mimics) is necessary for effective triage as medical intervention for true TIA/minor stroke is time-sensitive and TIA unit spots are a finite resource.

Methods: Prospective cohort study design utilizing patient referral data and TIA unit arrival times from a regional fast-track TIA unit on Vancouver Island, Canada, accepting referrals from emergency departments (ED) and general practice (GP).

Massive Vulvar Linear Verrucous Epidermal Nevus Presenting at Menarche.

Background: Epidermal nevi are benign hamartomatous growths of the skin that present at birth and develop in early childhood often linearly along the "lines of Blaschko." Verrucous linear epidermal nevi are the most common epidermal nevi and often are located on the trunk or extremities. There is minimal evidence regarding vulvar involvement and subsequent management of the associated cosmetic deformity in this anatomic location.

Exploring phlebotomy technique as a pre-analytical factor in proteomic analyses by mass spectrometry.

Multiple reaction monitoring mass spectrometry (MRM-MS) is an emerging technology for blood biomarker verification and validation; however, the results may be influenced by pre-analytical factors. This exploratory study was designed to determine if differences in phlebotomy techniques would significantly affect the abundance of plasma proteins in an upcoming biomarker development study. Blood was drawn from 10 healthy participants using four techniques: (1) a 20-gauge IV with vacutainer, (2) a 21-gauge direct vacutainer, (3) an 18-gauge butterfly with vacutainer, and (4) an 18-gauge butterfly with syringe draw.
