An Isolated Ureteropelvic Junction Injury Following a Low-impact Mechanical Fall.

Objective: To describe the presentation of a rare isolated ureteropelvic junction injury resulting from a mechanical fall on ice.

Materials And Methods: A 71-year-old previously healthy man presented to the emergency department at the University of Massachusetts Medical School 3 hours following falling on ice with complaints of gross hematuria and flank pain. Patient records were accessed via the institution's electronic medical records system between March 22, 2018 and April 22, 2018.

Antenatally diagnosed cloacal exstrophy variant with intravesical phallus in a twin pregnancy.

We report a rare case of covered cloacal exstrophy variant with a hemiphallus trapped within partially closed bladder halves. The persistence of the cloacal membrane until at least 18 weeks' gestation, confirmed by antenatal ultrasound scanning, is discordant with existing theories of embryogenesis of cloacal exstrophy. The clinical presentation highlights the need for careful assessment, before and during surgery, to obtain a complete understanding of the anatomic defect before gender assignment and appropriate reconstructive efforts.

Comparison of field performance of the Andersen N6 single stage and the SAS sampler for airborne fungal propagules.

Comparisons of two common bioaerosol samplers were made after sampling and enumeration of airborne fungal propagules in several office structures on a university campus in Southern California. Data collected on five occasions throughout the year showed that a Surface Air Systems (SAS) high flow portable sampler recovered consistently lower levels of colony forming units (cfu) than an Andersen N6 single stage impactor. There was no difference statistically between the samplers when concentrations of Cladosporium were compared.

Results of a multicenter trial of the CapSure (Re/Stor) Continence shield on women with stress urinary incontinence.

Objectives: To prospectively study the impact of the CapSure (Re/Stor) Continence shield for the treatment of stress urinary incontinence.

Methods: One hundred women with pure stress urinary incontinence were enrolled in a 6-month study. Objective measures of urine loss included pad weight test (PdWt) and provocative stress test (PST).

The effect of respirator dead space and lung retention on exposure estimates.

This paper develops, tests, and applies equations that predict the magnitude of the effect of lung retention and respirator dead space on average inhalation concentration and other related quantities. The equations were validated by numerical simulation and experimental measurement with a respirator on a mannequin connected to a breathing machine. Experimental data are presented verifying the applicability of the equations.
