Amin Rahpeyma, Saeedeh Khajehahmadi
Marsupialization is an option for treatment of large jaw cysts. In this article with a case report successful marsupialization of a large residual cyst is demonstrated. Selecting appropriate case and device is necessary for success. Dental implant insertion at the end of treatment restores the function. This article presents a simple device, made from disposable hypodermic syringe as marsupialization device.

The technique for successful surgical correction of an anomalous origin of the right coronary artery from the opposite aortic cusp with an aberrant course between the aorta and pulmonary artery is illustrated in a symptomatic 62-year-old woman. The intramural course of the right coronary artery traversed the tip of the commissure between the anterior and posterior leaflets, and its repair entailed unroofing of the intramural segment from inside the aortic intima. This technique required resuspension of the overlying commissure to maintain optimal aortic valve leaflet coaptation and prevent aortic insufficiency...

Translocation can be stressful for wildlife. Stress may be important in fauna translocation because it has been suggested that it can exacerbate the impact of infectious disease on translocated wildlife. However, few studies explore this hypothesis by measuring stress physiology and infection indices in parallel during wildlife translocations. We analysed faecal cortisol metabolite (FCM) concentration and endoparasite parameters (nematodes, coccidians and haemoparasites) in a critically endangered marsupial, the woylie (Bettongia penicillata), 1-3 months prior to translocation, at translocation, and 6 months later...

BACKGROUND: Skin-to-skin care (SSC), often referred to as 'kangaroo care' (KC) due to its similarity with marsupial behaviour of ventral maternal-infant contact, is one non-pharmacological intervention for pain control in infants. OBJECTIVES: The primary objectives were to determine the effect of SSC alone on pain from medical or nursing procedures in neonates compared to no intervention, sucrose or other analgesics, or additions to simple SSC such as rocking; and to determine the effects of the amount of SSC (duration in minutes), method of administration (e...

An overview of the literature on the chondrocranium of marsupial mammals reveals a relative conservatism in shape and structures. We document the histological cranial anatomy of individuals representing Monodelphis domestica, Dromiciops gliroides, Perameles sp. and Macropus eugenii. The marsupial chondrocranium is generally characterized by the great breadth of the lamina basalis, absence of pila metoptica and large otic capsules. Its most anterior portion (cupula nasi anterior) is robust, and anterior to it there are well-developed tactile sensory structures, functionally important in the neonate...

A male kowari (Dasyuroides byrnei) originating from a zoo facility was delivered for post mortem evaluation in Hungary. Acute lobar pneumonia with histopathologic changes resembling an adenovirus (AdV) infection was detected by light microscopic examination. The presence of an AdV was confirmed by obtaining partial sequence data from the adenoviral DNA-dependent DNA-polymerase. Although the exact taxonomic position of this novel marsupial origin virus could not be determined, pairwise identity analyses and phylogenetic calculations revealed that it is distantly related to other members in the family Adenoviridae...

OBJECTIVES: An epidemic of Ross River Virus (RRV) occurred in the South Pacific in 1979-1980, but it was not believed to occur endemically outside Australia and Papua New Guinea. We conducted a seroprevalence study to determine whether RRV has circulated in American Samoa after 1980. METHODS: RRV ELISA IgG were performed on 200 serum samples collected in American Samoa in 2010, and seroneutralisation tests on 60 representative samples. RESULTS: Of 196 results available for ELISA IgG, 145 (74%, 95% CI 67-80%) were seropositive...

In this study we explored the prevalence, type, location and severity of skeletal lesions in six species of Australian marsupial (Macropus giganteus, Notamacropus rufogriseus, Wallabia bicolor, Phascolarctos cinereus, Trichosurus vulpecula and Pseudocheirus peregrinus) from high and low-fluoride environments. Lesions occurred to varying extents in all species, and lesion distribution varied with biomechanical differences in gait and mastication. Bone fluoride levels increased with severity of periosteal hyperostosis...

One major innovation of mammals is the tribosphenic molar, characterized by the evolution of a neomorphic upper cusp (=protocone) and a lower basin (=talonid) that occlude and provide shearing and crushing functions. This type of molar is an evolutionarily flexible structure that enabled mammals to achieve complex dental adaptations. Among carnivorous mammals, hypercarnivory is a common trend that evolved several times among therians (marsupials, placentals, and stem relatives). Hypercarnivory involves an important simplification of the carnassial molar pattern from the ancestral tribosphenic molar pattern, with the modification of the triangular tooth crown, and the loss of several cusps and cuspids typical of the tribosphenic molar...

Multiple mammalian lineages independently evolved a definitive mammalian middle ear (DMME) through breakdown of Meckel's cartilage (MC). However, the cellular and molecular drivers of this evolutionary transition remain unknown for most mammal groups. Here, we identify such drivers in the living marsupial opossum Monodelphis domestica, whose MC transformation during development anatomically mirrors the evolutionary transformation observed in fossils. Specifically, we link increases in cellular apoptosis and TGF-BR2 signalling to MC breakdown in opossums...

Molecular phylogenomics investigates evolutionary relationships based on genomic data. However, despite genomic sequence conservation, changes in protein interactions can occur relatively rapidly and may cause strong functional diversification. To investigate such functional evolution, we here combine phylogenomics with interaction proteomics. We develop this concept by investigating the molecular evolution of the shelterin complex, which protects telomeres, across 16 vertebrate species from zebrafish to humans covering 450 million years of evolution...

BACKGROUND: Taxonomic identification of ticks obtained during a longitudinal survey of the critically endangered marsupial, Bettongia penicillata Gray, 1837 (woylie, brush-tailed bettong) revealed a new species of Ixodes Latrielle, 1795. Here we provide morphological data for the female and nymphal life stages of this novel species (Ixodes woyliei n. sp.), in combination with molecular characterisation using the mitochondrial cytochrome c oxidase subunit 1 gene (cox1). In addition, molecular characterisation was conducted on several described Ixodes species and used to provide phylogenetic context...

Marsupial reproduction differs significantly in anatomy and physiology from that of placental mammals. The gastrointestinal and urogenital tracts empty into a cloaca. Reproductive parameters include gestation and pouch time, as the fetus develops outside of the uterus. Captive marsupials discussed include sugar gliders), short-tailed opossums, Virginia opossums, and Tammar and Bennett's wallabies. Common disease conditions include joey eviction, pouch infections, mastitis, metritis, prostatitis, penile necrosis, and neoplasia...

Visibility continues to be a major problem during repair of obstructed total anomalous pulmonary venous connection (TAPVC) resulting in frequent use of deep hypothermia and low flow bypass. Sutureless technique for primary repair of anomalous pulmonary venous connection is fast becoming popular. In this described modification of sutureless technique through the lateral approach, the left atrium is marsupialized around the common pulmonary venous chamber, except on the right lateral aspect, providing a bloodless field with minimal retraction of heart facilitating the surgery at mild hypothermia...

The aim of this study is to report our preliminary experiences with regard to safety and feasibility of three-dimensional (3D) endoscopic lacrimal surgeries with a recently launched latest generation 3D endoscope. A 4-mm rigid three-dimensional (3D) endoscope (TIPCAM 1S 3D ORL(R), Karl Storz, Tuttlingen, Germany) was used. Fifteen patients who underwent various endoscopic lacrimal procedures by a single surgeon (MJA) were included. The procedures included probing with nasolacrimal intubation, cruciate marsupialization of intranasal cysts for congenital dacryoceles, powered endoscopic dacryocystorhinostomy, post-operative stent removal with ostium granuloma excision...

Interactions between the immune and endocrine systems are not well studied in marsupials and monotremes. One exception to this is the phenomenon of semelparity, which is well covered in the literature as this is an unusual reproductive strategy amongst mammals and is only observed in some dasyurid and didelphid marsupials. Thymus involution provides a direct link between the endocrine and immune systems and warrants further study in marsupials and monotremes. The thymus is a primary immune tissue which is essential for overall immune function...

In the effort to understand the evolution of mammalian brains, we have found that common relationships between brain structure mass and numbers of nonneuronal (glial and vascular) cells apply across eutherian mammals, but brain structure mass scales differently with numbers of neurons across structures and across primate and nonprimate clades. This suggests that the ancestral scaling rules for mammalian brains are those shared by extant nonprimate eutherians - but do these scaling relationships apply to marsupials, a sister group to eutherians that diverged early in mammalian evolution? Here we examine the cellular composition of the brains of 10 species of marsupials...

BACKGROUND: Members of the order Chlamydiales are known for their potential as human and veterinary bacterial pathogens. Despite this recognition, epidemiological factors such as routes of transmission are yet to be fully defined. Ticks are well known vectors for many other infections with several reports recently describing the presence of bacteria in the order Chlamydiales in these arthropods. Australian wildlife are hosts to an extensive range of tick species. Evidence is also growing that the marsupial hosts these ticks parasitise can also be infected by a number of bacteria in the order Chlamydiales, with at least one species, Chlamydia pecorum, posing a significant conservation threat...

Marsupial frogs have a unique reproductive mode in which females carry eggs enclosed in a sealed dorsal brood pouch. While most anurans are considered to be oviparous with lecithotrophic eggs, the extensively vascularized membrane of the brood pouch in marsupial frogs suggests potential opportunities for nutrient transfer. We tested for matrotrophy in the live-bearing Gastrotheca excubitor (Hemiphractidae), through feeding insects labelled with a (13)C-fatty acid and a (15)N-amino acid to brooding marsupial frogs...
