RESUMO
In this prospective study, we aimed to investigate whether surgical gowns become contaminated during surgery. Samples from the gowns of five surgeons during 19 surgeries were collected using sterile swabs in circular standard delimited areas on both wrists and the mid-chest at three time-points: immediately before surgical incision (t=0), 30 min (t=30), and 60 min (t=60) later. Additionally, at t=0 and t=60, three settle plates of plate count agar were positioned at 1.5 m from the ground and remained open for 20 min. The operating room temperature and relative humidity were monitored. The swabs were cultivated and incubated, and colony-forming units per gram (CFU/g) counts were measured. The CFU/g counts for bacteria or fungi did not differ among the three sampling sites. The surgeons' lateral dominance in manual dexterity did not influence the gowns' contamination. There were significant variations in the temperature and relative humidity over time, but not in the CFU/g counts. In conclusion, during the first hour of surgery, surgical gowns did not become a source of contamination and are an effective barrier against bacterial and fungal contamination even under non-standard surgical environmental conditions.

Cutaneous asthenia (CA) or Ehlers-Danlos Syndrome, in dogs, is a rare hereditary syndrome caused by autosomal dominant inheritance that causes collagen synthesis failure and leads to hyperextensibility and cutaneous fragility. This report describes a clinical case of canine CA of hereditary recessive origin, hitherto proven for other species, in an animal born from inbreeding healthy parents. A one-year-old female Maltese dog received clinical and surgical care for a cutaneous wound after a hygienic bath. The clinical history revealed the occurrence of other injuries that were caused by minor trauma and the consanguinity of the patient. During wound cleaning, the trichotomy and removal of an adhesive tape that was fixed to the skin generated new lacerations, which led to clinical suspicion of CA. CA was confirmed by calculating the cutaneous extensibility index (CEI), which was 22%, higher than the normal limit for the species (14.5%). The skin biopsy confirmed the clinical diagnosis, and the wound of the animal was treated routinely and healed clinically. Both dominant and recessive patterns have been well documented in cats; however, in dogs, only the dominant form has been reported in the literature. Our findings demonstrate that canine CA may result from autosomal recessive inheritance, and CA must be considered during diagnostic clinical approaches and breeding selections.(AU)

A história clínica revelou a ocorrência de outros ferimentos provocados por pequenos traumas e a origem consanguínea da paciente. Durante a limpeza da ferida, a tricotomia e a remoção de uma fita adesiva fixada à pele geraram novas lacerações levantando à suspeita clínica de astenia cutânea, confirmada pelo cálculo do índice de extensibilidade cutânea (CEI) que resultou em 22%, valor superior ao limítrofe de normalidade para a espécie (14,5%). A biopsia cutânea confirmou o diagnóstico clínico. A ferida do animal foi tratada rotineiramente resultando em cura clínica. Tanto as formas dominante e recessiva foram bem documentadas em gatos; entretanto, em cães, somente a forma dominante havia sido descrita pela literatura. Concluiu-se que a astenia cutânea canina pode advir de herança autossômica recessiva e isto deve ser considerado durante a abordagem clínica visando o diagnóstico e a seleção racial.(AU)

Background: Cutaneous horn is a circumscribed exophytic lesion composed of dense, compact keratin with hyperplasticepidermis, which is primarily orthokeratotic and may include foci of parakeratosis. The hyperkeratotic protuberance resembles a horn but lack bone. In humans, it is well-documented with a wide range of primary epidermal lesions identified.In dogs, the reports are rare and brief. The diagnosis is based on its appearance and excisional biopsy reveals the triggeringlesion. The objective of the present work is to describe the clinical presentation, predictive benignancy finds, treatmentand follow-up of a case of cutaneous horns that arose from anal mucocutaneous boundary in a dog.Case: A 6-month-old male Pug presented two tumors in the anus noted in the early months of life. Complete blood count,serum chemistry profile, surgery, histopathological analysis and postoperative outcome were performed. Possible relapseswere follow-up until 11 months after surgery. On physical examination, the dog was otherwise healthy. The two horn-liketumors were protruding from the mucocutaneous junction of the external anal sphincter in a sun-protected area. Both werehigher than wide in base or, in other words, they had a high height-to-base ratio. During surgery, the masses were excisedusing an electronic scalpel and sent to histopathological analysis. The post-operative care consisted of cephalexin andmeloxicam prescriptions. Also, it was recommended 0.9% NaCl solution wound flushing followed by topical chlorhexidinedigluconate solution (1%) whenever dirt or defecation were noticed. The surgical wound healed after two weeks by secondintention. Histopathology found well-delimited masses that covers the epidermis and dermis and displaces the cutaneousappendages towards the underlying musculature with an aggregate of lymphoplasmohistiocytic inflammatory infiltrate inthe adjacent...(AU)

RESUMO
ETHNOPHARMACOLOGICAL RELEVANCE: Tabebuia aurea (Silva Manso) Benth. & Hook. f. ex S. Moore is used as anti-inflammatory, analgesic and antiophidic in traditional medicine, though its pharmacological proprieties are still underexplored. In the bothropic envenoming, pain is a key symptom drove by an intense local inflammatory and neurotoxic event. The antivenom serum therapy is still the main treatment despite its poor local effects against pain and tissue injury. Furthermore, it is limited to ambulatorial niches, giving space for the search of new and more inclusive pharmacological approaches. AIM OF THE STUDY: evaluation of Tabebuia aurea hydroethanolic extract (HEETa) in hyperalgesia and neuronal injury induced by Bothrops mattogrossensis venom (VBm). MATERIALS AND METHODS: Stem barks from Tabebuia aurea were extracted with ethanol and water (7:3, v/v) to yield the extract HEETa. Then, HEETa was analyzed by LC-DAD-MS and its constituents were identified. Snake venoms were extracted from adult specimens of Bothrops mattogrossensis, lyophilized and kept at -20⯰C until use. Male Swiss mice, weighting 20-25â¯g, were used to hyperalgesia (electronic von Frey), motor impairment (Rotarod test) and tissue injury evaluation (histopatology and ATF-3 immunohistochemistry). Therefore, three experimental groups were formed: VBm (1â¯pg, 1â¯ng, 0.3⯵g, 1⯵g, 3 and 6⯵g/paw), HEETa orally (180, 540, 720, 810 or 1080â¯mg/kg; 10â¯mL/kg, 30â¯min prior VBm inoculation) and VBm neutralized (VBm: HEETa, 1:100 parts, respectively). In all set of experiments a control (saline group) was used. First, we made a dose-time-response course curve of VBm's induced hyperalgesia. Next, VBm maximum hyperalgesic dose was employed to perform HEETa orally dose-time-response course curve and analyses of VBm neutralized. Paw tissues for histopathology and DRGs were collected from animals inoculated with VBm maximum dose and treated with HEETa antihyperalgesic effective dose or neutralized VBm. Paws were extract two or 72â¯h after VBm inoculation and DRGs, in the maximum expected time expression of ATF-3 (72â¯h). RESULTS: From HEETa extract, glycosylated iridoids were identified, such as catalpol, minecoside, verminoside and specioside. VBm induced a time and dose dependent hyperalgesia with its highest effect seen with 3⯵g/paw, 2â¯h after venom inoculation. HEETa effective dose (720â¯mg/kg) decreased significantly VBm induced hyperalgesia (3⯵g/paw) with no motor impairment and signs of acute toxicity. HEETa antihyperalgesic action starts 1.5â¯h after VBm inoculation and lasted up until 2â¯h after VBm. Hyperalgesia wasn't reduced by VBm: HEETa neutralization. Histopathology revealed a large hemorragic field 2â¯h after VBm inoculation and an intense inflammatory infiltrate of polymorphonuclear cells at 72â¯h. Both HEETa orally and VBm: HEETa groups had a reduced inflammation at 72â¯h after VBm. Also, the venom significantly induced ATF-3 expression (35.37⯱â¯3.25%) compared with saline group (4.18⯱â¯0.68%) which was reduced in HEETa orally (25.87⯱â¯2.57%) and VBm: HEETa (19.84⯱â¯2.15%) groups. CONCLUSION: HEETa reduced the hyperalgesia and neuronal injury induced by VBm. These effects could be related to iridoid glycosides detected in HEETa and their intrinsic reported mechanism.

PURPOSE: To analyzed the healing effect of the powdered shell of the Megalobulimus lopesi snail on wounds of diabetic rats, since in non-diabetic rats the powdered shell presented healing potential. METHODS: Seventy-two Wistar rats (Rattus norvegicus albinus) were divided into three groups: Control group (GC.diab), no therapeutic intervention on the wound; Vehicle's Control group, topical via, in diabetic rats (GCvt.diab): Powder Shell Group (PC) applied topically (GPCvt.diab): Experimental group was administered topically shortly after wound dressing and once a day during the experimental period (3, 7, 14 and 21 days) the composition containing the powdered shell of the snail. The following variables related to the healing potential were analyzed: macroscopic one, where the capacity of reduction of the wound area was evaluated; histological analysis in HE, angiogenic activity, morphometric analysis (re-epithelization), leukocyte inflammatory infiltrate; leukocyte count and also differentiation in peripheral blood. RESULTS: The topical application in wounds of diabetic rats presented healing activity, accelerating wound closure, stimulating angiogenesis and being pro-inflammatory in the early and anti-inflammatory stages in the final times of the healing process. CONCLUSION: The topical administration of the powdered shell on wounds of diabetic patients becomes a therapeutic option of low cost, with ease in the administration and access as well.
