Pediatric intracranial arterial injuries by penetrating gunshot wounds: an institutional experience.

Purpose: Pediatric intracranial injuries due to penetrating gunshot wounds are a rare entity that is often fatal. A subset of patients may experience an intracerebral arterial injury; however, literature on the pediatric population is limited. This study analyzes a large institution's experience with pediatric head gunshot wounds and intracranial arterial injuries.

Attenuation of the Type IV Pilus Retraction Motor Influences Neisseria gonorrhoeae Social and Infection Behavior.

Unlabelled: Retraction of the type IV pilus (Tfp) mediates DNA uptake, motility, and social and infection behavior in a wide variety of prokaryotes. To date, investigations into Tfp retraction-dependent activities have used a mutant deleted of PilT, the ATPase motor protein that causes the pilus fiber to retract. ΔpilT cells are nontransformable, nonmotile, and cannot aggregate into microcolonies.

Cervical assessment in women with hysteroscopic uterine septum resection: a retrospective cohort study.

Objective: To estimate whether cervical length measured by transvaginal ultrasonography in women with a history of hysteroscopic uterine septum resection predicts spontaneous preterm birth <35 weeks' gestation.

Methods: This retrospective cohort study compared women who had undergone hysteroscopic metroplasty, and were subsequently pregnant with singleton gestations delivered January 2003 to December 2012, to a low-risk control group. Transvaginal ultrasonographic cervical lengths were measured 16-30 weeks' gestation.

Maternal and perinatal outcomes of extreme obesity in pregnancy.

Objective: To evaluate the effects of extreme obesity (pre-pregnancy BMI ≥ 50.0 kg/m2) in pregnancy on maternal and perinatal outcomes.

Methods: We conducted a population-based cohort study using the Newfoundland and Labrador Perinatal Database to compare obstetric outcomes in women with extreme obesity and those with a normal BMI (pre-pregnancy BMI 18.

Transvaginal ultrasonography to predict preterm birth in women with bicornuate or didelphus uterus.

Objective: To estimate whether cervical length measured by transvaginal ultrasonography (TVUS) in women with uterine anomalies predicts spontaneous preterm birth (SPTB).

Methods: This retrospective cohort study compared women with a uterine anomaly who were pregnant with singleton gestations and delivered August 2000 to April 2008 to a low risk control group. Transvaginal ultrasonographic cervical lengths were measured 16-30 weeks gestation.
