Comfort, stability and body posture in wheelchair cushions: a preliminary study with able bodied subjects

Long term wheelchair usage has been related to a number of problems, among which pressure ulcers are one of most concern. The design of wheelchair seat cushions has been of increasing interest among researchers, as it can influence seat interface pressure and user's comfort. The aim of this study was to investigate the subjects' perception comfort, stability and body posture of six different commercially available wheelchair cushions. The evaluation was through a questionnaire, where the subjects rate their perceptions on a ten point visual analog scale after staying seated in the cushion for two minutes. The results shows that the Roho^TM aircell cushion was preferred by the users, while the least preferred one was the water cushion. Individuals' subjective perceptions may compliment objective data on seat interface pressure, thus contributing to a more complete view of the users' experience during wheelchair cushion usage.

Hepatitis C infection: challenges in dental management and diagnosis of extrahepatic manifestations

Hepatitis C is associated with autoimmune diseases, hepatocellular carcinoma,and extrahepatic manifestations that, in conjunction, may seriously compromise the patient's quality of life. We herein describe a case of chronic hepatitis C with oral manifestations and discuss some implications for diagnosis and treatment. A 63-year-old woman complaining of spontaneous bleeding of the oral mucosa presented with bilateral asymmetric ulcers surrounded by white papules and striae on the buccal mucosa. Her medical history revealed leucopenia, thrombocytopenia, and skin lesions associated with chronic hepatitis C. Propranolol and ranitidine had recently been prescribed. Lichen planus, lichenoid reaction, and erythema multiforme were considered in the differential diagnosis. Histopathological analysis revealed lymphocytic infiltrate in a lichenoid pattern. The lesions partially healed after 1 week and completely regressed after 6 months, despite the maintenance of all medications; no recurrence was observed. The final diagnosis was oral lichen planus associated with hepatitis C. Chronic hepatitis C may present oral manifestations, which demand adjustments in dental treatment planning. Medication side effects may interfere with the clinical presentation and course of the disease and should be accounted for in the differential diagnosis. The possibility of spontaneous remission of oral lichen planus should always be considered, especially when putative etiological factors of a lichenoid lesion are withdrawn in an attempt to differentiate oral lichen planus from lichenoid lesions. This case emphasizes the importance of recognizing the extrahepatic manifestations of hepatitis C as a cause of increased morbidity.

Testes preliminares de motilidade intestinal e toxicidade oral aguda com extrato de cascas pulverizadas de Endopleura uchi (Huber) Cuatrec: (Humiriaceae) em camundongos

The aim of this work was to analyze the acute oral toxicity and the effects on intestinal motility of the extract obtained through decoction 20% (m/v) of Endopleura uchi, popularly known as "uxi-amarelo", a native plant from the Brazilian Amazon. The plant is used indiscriminately against several diseases: arthritis, cholesterol, diabetes, ulcers, myomas, and intestinal illnesses in general, among others. The present results show that there were no significant alterations in intestinal motility and that the extract does not present signs of toxicity, showing its safety for consumption purposes.

Intramammary coinfection by vaccinia virus and staphylococcus aureus in a bovine vaccinia outbreak

Introduction: Bovine vaccinia virus (VACV) is a well-known zoonotic agent related to exanthemous lesions in skin and mucous membranes of dairy cattle and humans, characterized by the formation of vesicles, pustules and ulcers. Mastitis is one of the most common infectious diseases of dairy herds. Bovine mammary infections are caused mainly by bacterial microorganisms, especially staphylococci. To the best of our knowledge, intramammary coinfection with VACV and Staphylococcus aureus in cows has not been reported previously. Case presentation: During an outbreak of exanthematic bovine VACV infection with animals showing vesicles, pustules and haemorrhagic ulcers on the teats, milk samples were collected for mastitis detection. Conclusion: The present report describes a case of intramammary coinfection by VACV and S. aureus in a bovine VACV outbreak.

Uso de plasma rico em plaquetas em úlceras de córnea em cães

This study aims to clinically and macroscopically evaluate the adjuvant therapy with platelet-rich plasma in the form of eyedrops or clot, for corneal ulcers in dogs treated at the Veterinary Ophthalmology Service. We analyzed 20 eyes diagnosed with ulcerative keratitis, divided into two experimental groups. The eyedrop group (GC) was composed of eyes treated topically with eyedrops of autologous plateletrich plasma (PRP), and the clot group (GT) was composed of eyes treated with a platelet-rich clot and covered with a third eyelid for retention of the clot. The groups were evaluated by clinical and macroscopic analysis and by the analysis of epithelial defect reduction, at different times, at three, five, ten, 15 and 30 days, except for the third day in GT. The coverage of the third eyelid was removed on the fifth day. In both groups the inflammation signs reduced, there was an improvement in ocular sensibility and proper repair of epithelial defect. All GT eyes and 70% GC eyes showed complete healing on the fifth day, the remainder of GC completed healing on the tenth day. PRP in the form of eyedrops and clot is an excellent adjuvant therapy to be instituted in the clinical treatment for corneal ulcer in dogs, because it decreases the inflammatory signs and the ocular pain and it potentially assists in healing epithelial defects.

Documentação química de espécies do gênero Casearia (Salicaceae) de importância ecológica, econômica e medicinal

The Casearia genus (Salicaceae) is well known because of the medicinal use of its species. Among them, a noteworthy one is the C. sylvestris specie because it already has studies concerning its antiproliferative and/or cytotoxic activity in tumor cells. Furthermore, this specie is popularly used against snake bites, in gastric ulcers treatment and as anti-inflammatory. As well as this, there are other species from this same genus which have been poorly studied, such as the following species: C. decandra, C. grandiflora, C. javitensis, C. arborea, C. lasiophylla and C. ulmifolia. However, several biological activities have been reported for them. In this context, the aim of this project, besides of contributing to the Casearia genus studies, is to study those six species through the analysis and documentation of their leaves' chemical composition (aqueous, ethanolic and hexanic extracts), using analytical separation techniques coupled with spectroscopic techniques, such as UHPLC-DAD, GC-MS and NMR 1H, which will assist the identification of new secondary metabolites in this genus. Moreover, another goal of this present work is aiming the bioprospection of substances with medicinal and economical potential and finally promote the systematic study of some biological activities, such as antimicrobial and cytotoxicity bioassays. A wide variety of metabolites was identified in those three types of extracts, being most of them detected for the first time in Casearia genus, highlighting C. lasiophylla and C. decandra for featuring antimicrobial activity against Staphylococcus aureus.

JAVMA37-43 Anthrax in Swine

Anthrax is not commonly considered so important a menace to swine as it is to other forms of live stock, in which the disease is apt to declare itself with terrifying severity. In comparison with the marked mortality frequently observed in cattle, the tangible losses caused by anthrax in swine seem negligible. As recent as 25 years ago, there still were observers who sincerely doubted the occurrence of the disease in hogs and this opinion found some support in the many reported failures to induce the infection in that animal species by artificial methods.
