Sonographic evaluation of hydronephrosis in the pediatric population: is well-tempered sonography necessary?

Objectives: Standardized protocols exist for diuretic renography. There are no specific guidelines regarding hydration before renal sonography. This study assessed the importance of the hydration status by sonographic measurements of the anteroposterior diameter and its effect on Society for Fetal Urology (SFU) hydronephrosis grading.

Integrated printed circuit board device for cell lysis and nucleic acid extraction.

Preparation of raw, untreated biological samples remains a major challenge in microfluidics. We present a novel microfluidic device based on the integration of printed circuit boards and an isotachophoresis assay for sample preparation of nucleic acids from biological samples. The device has integrated resistive heaters and temperature sensors as well as a 70 μm × 300 μm × 3.

Ruptured ectopic pregnancy presenting 3 years after supracervical hysterectomy.

An ectopic pregnancy after a hysterectomy is a rare event, with about 40 reported cases since it was first identified by Wendeler in 1895. There are even fewer cases reported of an ectopic pregnancy occurring years after a hysterectomy has been performed. This case illustrates the sonographic and computed tomographic (CT) findings in the setting of abdominal pain in a woman of childbearing age and highlights the need to obtain a urine pregnancy test as part of the workup for abdominal pain in women, even if a history of a hysterectomy has been given.

Significance of cultural beliefs in presentation of psychiatric illness: a case report of selective mutism in a man from Nepal.

A 22-year-old active duty E1 Nepalese male who recently emigrated from Nepal suddenly exhibited strange behaviors and mutism during Advanced Individual Training. After receiving care from a hospital near his unit, he was transferred to Walter Reed Army Medical Center Inpatient Psychiatry for further evaluation and treatment. Although he was admitted with a diagnosis of psychosis not otherwise specified (NOS), after consideration of cultural factors and by ruling out concurrent thought disorder, a diagnosis of selective mutism was made.
