Case Report: Penile Strangulation Secondary to Hair Tourniquet.

Penile strangulation is a rare condition in children caused by circumferential constriction of the coronal sulcus by constricting material, commonly thin maternal hair. Vague presenting symptoms often makes diagnosis difficult, but delay in diagnosis can lead to a variety of severe complications including urethral injury and penile necrosis. Providers must have a high index of suspicion and carry out a careful examination to identify maternal hair strands that may bury deep within penile edema.

Dimethyl sulfoxide (DMSO) as intravesical therapy for interstitial cystitis/bladder pain syndrome: A review.

Aims: The purpose of this review is to update the current understanding of dimethyl sulfoxide (DMSO) and its role in the treatment of interstitial cystitis (IC).

Methods: A systematic review was conducted using the PRIMSA checklist to identify published articles involving intravesical DMSO for the treatment of IC.

Results: Thirteen cohort studies and three randomized-controlled trials were identified.

Pulmonary artery endothelial cell phenotypic alterations in a large animal model of pulmonary arteriovenous malformations after the Glenn shunt.

Background: Longevity of the superior cavopulmonary connection (SCPC) is limited by the development of pulmonary arteriovenous malformations (PAVM). The goal of this study was to determine whether phenotypic changes in pulmonary artery endothelial cells (PAEC) that favor angiogenesis occur with PAVM formation.

Methods: A superior vena cava to right pulmonary artery connection was constructed in 5 pigs.
