Hand, foot, and mouth disease is a viral infection related to coxsackieviruses A5, A6, A9, and A10, coxsackieviruses B2 and B5, and echovirus 11. It generally affects children, but this article presents a clinical case of a young woman with hand, foot, and mouth disease. Patients with this disease have oral and skin lesions that may be confused with other diseases. The differential diagnosis is very important because both dental and medical professionals may misdiagnose the disease and sometimes prescribe an inappropriate medication.

Purpose: To establish an experimental model of traumatic ulcer in rat cheek mucosa for utilization in future alternative therapy studies. Methods: A total of 60 adult male rats (250 - 300g) were used. Ulceration of the left cheek mucosa was provoked by abrasion using a n o 15 scalpel blade. The animals were observed for 10 days, during which they were weighed and their ulcers were measured. The histological characteristics were analyzed and scored according to the ulcer phase. In the statistical analysis, a value of p<0.01 was considered a statistically significant response in all cases. Results: During the five first days, the animals lost weight (Student t test, p<0.01). The ulcerated area receded linearly over time and was almost completely cicatrized after 10 days (ANOVA, Tendency post-test, p<0.0001). Groups on days 1, 2 and 3 days displayed similar results, but a decrease in scores were observed after the 4th day. Conclusion: The proposed cheek mucosa ulcer model in rats can be considered an efficient, low-cost, reliable, and reproducible method.

Introduction. Necrotizing sialometaplasia is a benign, self-limiting and rare inflammatory disease which, on clinical and histological examination, mimics malignant neoplasms. Case report. We report the case of a healthy 25-year-old Caucasian woman with a three-week history of a painless lump on her hard palate. Oral examination revealed a nodule consisting of two lobules on the right side that measured 2.5 cm. Her mucosa was normal in color and a fluctuant area was detected in the posterior region upon palpation. Our patient was submitted to incisional biopsy and histopathological examination. The histological diagnosis was necrotizing sialometaplasia. The lesion had healed spontaneously after 30 days, with observed signs of involution of the nodule. Conclusion: Histopathological examination is necessary for the diagnosis of necrotizing sialometaplasia because the clinical features of this condition can mimic other diseases, particularly malignant neoplasms. © 2011 Oliveira Alves et al; licensee BioMed Central Ltd.

Clinical, histopathological and ultrastructural findings of caprine dystrophic epidermolysis bullosa (DEB) with autosomal recessive inheritance are reported. The goats presented with exungulation, erosions, crusts and scars on the skin and ulcers in the oral cavity. Microscopically, the skin showed subepidermal separation with clefts filled occasionally with clear eosinophilic fluid, cellular debris or neutrophils. Ultrastructurally, the site of blister formation was the sublamina densa in the epidermal basement membrane zone. In skin with blister formation and in clinically uninvolved skin, the basal lamina was preserved, but the anchoring fibrils were sparse and rudimentary. A twin brother of an affected kid was mated over 5 years with his mother; three out of the 10 kids born presented with epidermolysis bullosa, indicating that the disease has an autosomal recessive mode of inheritance. It is suggested that the disease is similar to human severe generalized recessive DEB. © 2012 Elsevier Ltd.

Size distributions of expiratory droplets expelled during coughing and speaking and the velocities of the expiration air jets of healthy volunteers were measured. Droplet size was measured using the Interferometric Mie imaging (IMI) technique while the Particle Image Velocimetry (PIV) technique was used for measuring air velocity. These techniques allowed measurements in close proximity to the mouth and avoided air sampling losses. The average expiration air velocity was 11.7 m/s for coughing and 3.9 m/s for speaking. Under the experimental setting, evaporation and condensation effects had negligible impact on the measured droplet size. The geometric mean diameter of droplets from coughing was 13.5m and it was 16.0m for speaking (counting 1 to 100). The estimated total number of droplets expelled ranged from 947 – 2085 per cough and 112 – 6720 for speaking. The estimated droplet concentrations for coughing ranged from 2.4 - 5.2cm-3 per cough and 0.004 – 0.223 cm-3 for speaking.

In recent decades a number of Australian artists and teacher/artists have given serious attention to the creation of performance forms and performance engagement models that respect children’s intelligence, engage with themes of relevance, avoid the cliche´s of children’s theatre whilst connecting both sincerely and playfully with current understandings of the way in which young children develop and engage with the world. Historically a majority of performing arts companies touring Australian schools or companies seeking schools to view a performance in a dedicated performance venue engage with their audiences in what can be called a ‘drop-in drop-out’ model. A six-month practice-led research project (The Tashi Project) which challenged the tenets of the ‘drop-in drop-out’ model has been recently undertaken by Sandra Gattenhof and Mark Radvan in conjunction with early childhood students from three Brisbane primary school classrooms who were positioned as co-researchers and co-artists. The children, researchers and performers worked in a complimentary relationship in both the artistic process and the development of product.

Aims To determine the effect of nutritional status on the presence and severity of pressure ulcers in statewide? public healthcare facilities, in Queensland, Australia. Research Methods A multicentre, cross sectional audit of nutritional status of a convenience sample of subjects was carried out as part of a large audit of pressure ulcers in a sample of state based public healthcare facilities in 2002 and 2003. Dietitians in 20 hospitals and six residential aged care facilities conducted single day nutritional status audits of 2208 acute and 839 aged care subjects using the Subjective Global Assessment. The effect of nutritional status on the presence, highest stage and number of pressure ulcers was determined by logistic regression in a model controlling for age, gender, medical specialty and facility location. The potential clustering effect of facility was accounted for in the model using an analysis of correlated data approach. Results Subjects with malnutrition had an adjusted odds risk of 2.6 (95% CI 1.8-3.5, p<0.001) of having a pressure ulcer in acute facilities and 2.0 (95% CI 1.5-2.7, p<0.001) for residential aged care facilities. There was also increased odds risk of having a pressure ulcer, having a higher stage pressure ulcer and a higher number of pressure ulcers with increased severity of malnutrition. Conclusion Malnutrition was associated with at least twice the odds risk of having a pressure ulcer of in public healthcare facilities in Queensland. Action must be taken to identify, prevent and treat malnutrition, especially in patients at risk of pressure ulcer.

Glacial cycles during the Pleistocene reduced sea levels and created new land connections in northern Australia, where many currently isolated rivers also became connected via an extensive paleo-lake system, 'Lake Carpentaria'. However, the most recent period during which populations of freshwater species were connected by gene flow across Lake Carpentaria is debated: various 'Lake Carpentaria hypotheses' have been proposed. Here, we used a statistical phylogeographic approach to assess the timing of past population connectivity across the Carpentaria region in the obligate freshwater fish, Glossamia aprion. Results for this species indicate that the most recent period of genetic exchange across the Carpentaria region coincided with the mid- to late Pleistocene, a result shown previously for other freshwater and diadromous species. Based on these findings and published studies for various freshwater, diadromous and marine species, we propose a set of 'Lake Carpentaria' hypotheses to explain past population connectivity in aquatic species: (1) strictly freshwater species had widespread gene flow in the mid- to late Pleistocene before the last glacial maximum; (2) marine species were subdivided into eastern and western populations by land during Pleistocene glacial phases; and (3) past connectivity in diadromous species reflects the relative strength of their marine affinity.

This paper explores one of the ways in which the Somerset region in the United Kingdom, devastated by the foot and mouth epidemic in 2001, is trying to free itself from recurring negative representations and create more positive images of the area. After the epidemic projects were sought that would promote a more positive image and draw tourists back to the area. One of these projects drew on literary tourism to reinvigorate the site. A Walking and Bridle trail called the ‘Coleridge Way Walk’ has been implemented to take the images of the area from ones of disease and dirtiness to ones of Romantic longing. The Coleridge Way Walk uses past imaginings to re-energise the area. This energy, in part, comes from ‘re-imagining’ the site through past imaginings. The Coleridge Way Walk uses the past to create future direction for the once tainted area.
