STUDY OBJECTIVE: Gartner duct cysts (GDC) are rare embryological remnants of the mesonephric duct with the majority of cases discovered incidentally in asymptomatic patients. The largest prior published series evaluating surgical management of GDC included 4 patients. The present study aims to determine the manifestations and outcomes of surgically managed patients with GDC with important implications for surveillance, monitoring, and management of patients. DESIGN: Retrospective chart review DESIGN: Classification: Canadian Task Force Classification III SETTING: Tertiary care center PATIENTS: All women diagnosed with GDC from 1/1994-4/2014 at our institution were identified...

Paraurethral cyst is a benign cystic disorder of anterior vaginal wall. Many secondary complications have been described in literature, but stone formation in the cyst is a rare phenomenon. We are reporting a case of a 35-year-old multiparous woman who presented with lower urinary tract symptoms, dysuria, and dyspareunia. She was diagnosed as a case of the paraurethral cyst with stones and was managed successfully. Various differential diagnoses have been suggested, most important being urethral diverticulum, ruled out by urethroscopy...

Orientation selectivity in primary visual cortex (V1) has been proposed to reflect a canonical computation performed by the neocortical circuitry.  While orientation selectivity has been reported in all mammals examined to date, the degree of selectivity and the functional organization of selectivity varies across clades. The differences in degree of orientation selectivity are large from reports in marsupials that only a small subset of neurons are selective to studies in carnivores in which it is rare to find a neuron lacking selectivity...

Thymus-dependent lymphocytes (T cells) are a critical cell lineage in the adaptive immune system of all jawed vertebrates. In eutherian mammals the initiation of T cell development takes place prenatally and the offspring of many species are born relatively immuno-competent. Marsupials, in contrast, are born in a comparatively altricial state and with a less well developed immune system. As such, marsupials are valuable models for studying the peri- and postnatal initiation of immune system development in mammals...

The temporal activity of animals is an outcome of both biotic and abiotic factors, which may vary along the geographic range of the species. Therefore, studies conducted with a species in different localities with distinct features could elucidate how animals deal with such factors. In this study, we used live traps equipped with timing devices to investigate the temporal activity patterns of the didelphid Gracilinanus agilis in two dry-woodland areas of the Brazilian savanna (Cerrado). These areas were located about 660 km apart, one in Central Brazil and the other in Southeastern Brazil...

INTRODUCTION AND HYPOTHESIS: We present a simple approach to the marsupialization of a Skene's gland cyst. METHODS: Our technique facilitates suture placement to exteriorize the cyst wall to efficiently treat a distal Skene's gland cyst and reduce the risk of recurrence. CONCLUSION: Marsupialization is an accepted option for the surgical management of Skene's gland cyst. This technique is an effective and streamlined approach to Skene's gland marsupialization...

: The human genome displays a rich fossil record of past gamma-retrovirus infections, yet no current epidemic is evident, despite environmental exposure to viruses that infect human cells in vitro. Feline leukemia viruses (FeLVs) rank high on this list, but domestic or workplace exposure has not been associated with detectable serological responses. Non-specific inactivation of gamma-retroviruses by serum factors appears insufficient to explain these observations. To investigate further we explored the susceptibility of primary and established human cell lines to FeLV-B, the most likely zoonotic variant...

PURPOSE: To investigate and compare the probability of recurrence of keratocystic odontogenic tumors (KCOTs) for different variables and treatment protocols. MATERIALS AND METHODS: An electronic search was undertaken in April 2016 that included clinical series of KCOTs reporting recurrences. Untransformed proportions and meta-analyses were performed to estimate the probability/risk of recurrence, according to several variables. RESULTS: A total of 94 publications were included (6427 KCOTs, 1464 recurrences)...

PURPOSE: Few studies have focused on the intranasal localization of the lacrimal sac during endoscopic dacryocystorhinostomy: landmarks in order to find the medial wall of the lacrimal sac have been described, but there is a lack of description of methods for the verification of the complete marsupialization of the lacrimal sac during surgery. In this report, we propose an easy and effective method for certain intraoperative identification of lacrimal sac. METHODS: A method in order to verify the effective marsupialization of the lacrimal sac is applied and described: to ensure that the opening of the sac in the nasal cavity is complete, the surgeon should identify the Rosenmuller valve, which is the end of the common canaliculus in the lacrimal sac...

Although it has been claimed that marsupials possess a lower density of isocortical neurons compared with other mammals, little is known about cross-cortical variation in neuron distributions in this diverse taxonomic group. We quantified upper layer (layers II-IV) and lower layer (layers V-VI) neuron numbers per unit of cortical surface area in three diprotodont marsupial species (two macropodiformes, the red kangaroo and the parma wallaby, and a vombatiform, the koala) and compared these results to eutherian mammals (e...

Alterations to the basal attachment points between the epithelium of the uterus and the underlying tissue in early pregnancy affect how easily the epithelium can be invaded by the implanting embryo. Attachment points- focal adhesions- disassemble to facilitate highly invasive implantation in rats, but species with less invasive implantation, including marsupials, may require different basal alterations for successful pregnancy. Here we used immunofluorescence microscopy and Western blotting to conduct the first study of basal plasma membrane dynamics in the uterus during marsupial pregnancy...

Tasmanian devils (Sarcophilus harrisii) are the largest carnivorous marsupial in Australia. Currently many animals are being held in captivity as a management procedure to combat Devil Facial Tumor Disease. Only one published study thus far has investigated nutrition in Tasmanian devils, determining their maintenance energy requirements and digestibility on a rodent diet. More information is needed on Tasmanian devil nutritional and gastrointestinal function to aid in their management. Our study aimed to investigate the current nutritional status of Tasmanian devils in a captive population and functional morphology and histology of their gastrointestinal tract...

REVIEW
Delaney Burnard, Adam Polkinghorne
Members of the order Chlamydiales are biphasic intracellular pathogens known to cause disease in both humans and animals. As we learn more about the genetic diversity of this group of pathogens, evidence is growing that these bacteria infect a broader range of animal hosts than previously thought. Over 400 host species are now documented globally with the majority of these being wild animals. Given the impact of chlamydial infections on humans and domesticated animals, the identification of members of the order Chlamydiales in wildlife raises significant questions over a) their impact on animal health and b) the relationships to those strains also found in humans and domestic animals...

Marsupial mammal relatives (stem metatherians) from the Mesozoic Era (252-66 million years ago) are mostly known from isolated teeth and fragmentary jaws. Here we report on the first near-complete skull remains of a North American Late Cretaceous metatherian, the stagodontid Didelphodon vorax. Our phylogenetic analysis indicates that marsupials or their closest relatives evolved in North America, as part of a Late Cretaceous diversification of metatherians, and later dispersed to South America. In addition to being the largest known Mesozoic therian mammal (node-based clade of eutherians and metatherians), Didelphodon vorax has a high estimated bite force and other craniomandibular and dental features that suggest it is the earliest known therian to invade a durophagous predator-scavenger niche...

We aimed to validate the use of 1) the modified agglutination test and a polymerase chain reaction (PCR) protocol in detecting Toxoplasma gondii infection in quenda (Isoodon obesulus) and brushtail possums (Trichosurus vulpecula); 2) immunofluorescence microscopy of feces and a PCR and sequencing protocol in detecting Giardia spp. infection in quenda; and 3) a fecal flotation protocol in detecting gastrointestinal helminth infections of quenda. Quenda and brushtail possum carcasses, and samples from trapped quenda, were tested with 2 parasite detection tests per parasite, and results were modeled using Bayesian latent class analysis to estimate test sensitivity and specificity...

Deltatheroidans are primitive metatherian mammals (relatives of marsupials), previously thought to have become extinct during the Cretaceous mass extinction. Here, we report a tiny new deltatheroidan mammal (Gurbanodelta kara gen. et sp. nov.) discovered at the South Gobi locality in China (Xinjiang Province) that is the first Cenozoic record of this clade and renders Deltatheroida a Lazarus taxon (with a new record 10 million years younger than their supposed extinction). The vertebrate fauna associated with Gurbanodelta is most similar to that from the slightly older late Paleocene Subeng locality in Inner Mongolia...

The monophyletic clade Monotremata branches early from the rest of the mammalian crown group in the Jurassic and members of this clade retain many ancestral mammalian traits. Thus, accurate and detailed anatomical descriptions of this group can offer unique insight into the early evolutionary history of Mammalia. In this study, we examine the inner ear anatomy of two extant monotremes, Ornithorhynchus anatinus and Tachyglossus aculeatus, with the primary goals of elucidating the ancestral mammalian ear morphology and resolving inconsistencies found within previous descriptive literature...

Bandicoots (Peramelemorphia) are a unique order of Australasian marsupials whose sparse fossil record has been used as prima facie evidence for climate change coincident faunal turnover. In particular, the hypothesized replacement of ancient rainforest-dwelling extinct lineages by antecedents of xeric-tolerant extant taxa during the late Miocene (~10 Ma) has been advocated as a broader pattern evident amongst other marsupial clades. Problematically, however, this is in persistent conflict with DNA phylogenies...
