In this review we describe lessons learned from the authors' series of patients born with the most complex of congenital anorectal problems, cloacal malformations, with the hope to convey the improved understanding and surgical treatment of the condition's wide spectrum of complexity learned from patients cared for over the last 25 years. This includes a series of 490 patients, 397 of whom unde...

OBJECTIVE Sex assignment to newborns with ambiguous genitalia is controversial. Our objective was to determine the attitudes and practices of pediatric urologists on this subject. STUDY DESIGN A survey of fellows in the Urology Section of the American Academy of Pediatrics was completed by 185/228 (81%). The survey referred to two cases, masculinized 46XX congenital adrenal hyperplasia (CAH) ...

A study was conducted to determine the effect of foam extract on sperm motility in the male Japanese quail (Coturnix coturnix japonica). Adult male quails (<12 weeks) of heavy body weight strain were housed in individual cages and divided into 5 groups according to the size of their cloacal glands. The data indicated that the size of the cloacal gland was positively correlated with the frequenc...

Highly pathogenic avian influenza (HPAI) H5N1 virus incursions from migrating birds have occurred multiple times in Romania since 2005. Beginning in September 2008 through April 2013, seasonal sentinel surveillance for avian influenza A viruses (AIVs) using domestic geese (Anser cygnoides) and ducks (Anas platyrhynchos) in the Danube Delta was established by placing 15 geese and 5 ducks at seve...

Bone morphogenetic protein (Bmp) signaling has long been known to be important for the early development of the ventral mesoderm, including blood, vasculature and kidney cells. Although Bmp genes are continually expressed in the ventral cells throughout gastrulation and somitogenesis, previous studies in zebrafish have not addressed how the role of Bmp signaling changes over time to regulate ve...

The gut microbiome of herbivorous animals consists of organisms that efficiently digest the structural carbohydrates of ingested plant material. Green turtles (Chelonia mydas) provide an interesting model of change in these microbial communities because they undergo a pronounced shift from a surface-pelagic distribution and omnivorous diet to a neritic distribution and herbivorous diet. As an a...

Pheromones play an important role in modifying vertebrate behavior, especially during courtship and mating. Courtship behavior in urodele amphibians often includes female exposure to secretions from the cloacal gland, as well as other scent glands. The first vertebrate proteinaceous pheromone discovered, the decapeptide sodefrin, is a female attracting pheromone secreted by the cloacal gland of...

Two candidate formalin-inactivated vaccines, made from high-growth reassortant viruses with the HA and NA genes from avian viruses in a background of genes derived from A/Puerto Rico/8/34 (PR8), were prepared against H5N1 and H9N2 subtypes (designated as H5N1/PR8 and H9N2/PR8, respectively). These viruses bear the genotypes, antigenicity, and attenuation in mouse models that are desirable in ca...

PURPOSE The surgical correction of bladder exstrophy to achieve continence with voiding remains a challenging problem for the urologist. Since 1989 we have performed complete primary repair for exstrophy based on the concept that the primary defect of bladder and cloacal exstrophy is anterior herniation. Thus, the bladder and urethra must be treated as a single unit to move them posteriorly int...
