RESUMO

O presente trabalho teve como objetivo avaliar a percepção de estudantes de medicina veterinária e profissionais médicos veterinários quanto ao leite destinado ao consumo humano. O estudo foi realizado por meio da aplicação de um questionário elaborado na plataforma Google Forms®. Das 70 respostas obtidas, 43 (61,4%) foram de profissionais graduados em medicina veterinária e 27 (38,6%) graduandos nesse curso. As respostas apresentadas mostraram que 60 (85,7%) dos indivíduos consomem leite, sendo que o produto de maior consumo é o leite UAT, representado por 42 pessoas (70%). Dos 10 indivíduos que não consomem leite, 6 (60%) não o fazem por não se adaptarem ao sabor do leite, 2 (20%) por receio de fraudes, 1 (10%) pela intolerância à lactose e 1 (10%) pela alergia à proteína do leite. Quanto à presença de conservantes no leite UAT, 46 indivíduos (65,7%) acreditam que este possui conservantes. Quanto à veiculação de doenças, 68 indivíduos (97,1%) acreditam que o leite seja passível de transmitir doenças. Quandoquestionados sobre o que os auxilia na decisão de compra do leite, a maioria informou (47 participantes -67,1%) observar a data de fabricação e de validade. Observou-se que mesmo entre os profissionais que possuem conhecimento prévio sobre tecnologia e inspeção de leite, ainda existe o conceito de que o leite UAT possui conservantes, sendo menos saudável. Entretanto, os entrevistados demonstraram conhecimento sobre a possibilidade de veiculação de patógenos no leite que não tenha sido submetido ao tratamento térmico.(AU)


The present study aimed to evaluate the perception of veterinary medicine students and veterinary medical professionals regarding milk intended for human consumption. The study was carried out by applying a questionnaire in Google Forms®. Of the 70 responses obtained, 43 (61.4%) were from professionals graduated in veterinary medicine and 38.6% were students. The answers presented showed that 60 (85.7%) of the individuals consume milk, with the highest consumption product being UAT milk (42 participants, 70%). Of the 10 individuals who do not consume milk, 6 (60%) do not do so because they do not adapt to the taste of milk, 20% for fear of fraud, 1 (10%) for lactose intolerance and 1 (10%) for allergy to milk protein. As for the presence of preservatives in UAT milk, 46 (65.7%) believe that it has preservatives. As for the transmission of diseases, 68 (97.1%) believe that milk is susceptible. When asked what helps in the decision to buy milk, the majority (47 participants, 67.1%) reported observing the expiration date of manufacture. Even professionals who have previous knowledge about milk technology and inspection, there is still the concept that UAT milk has a preservative, being less healthy. However, there is an understanding of the possibility of transmission of pathogens in milk that has not been subjected to heat treatment.(AU)

RESUMO

This study aimed to compare the effects of different coinduction agents on the duration and dose of propofol in healthy cats. Six cats aged 4.8 ± 1.0 years and weighing 4.4 ± 1.1 kg participated in 4 treatment groups of propofol combined with: saline or control group (TC); ketamine 2 mg/kg (Tket); fentanyl 1 µg/kg (Tfen); or midazolam 0.3 mg/kg (Tmid). Twenty minutes following premedication with dexmedetomidine at 10 µg/kg, induction followed the same protocol in all groups, starting with a propofol bolus of 1 mg/kg over 1 minute followed by an adjuvant, then propofol again at 1 mg/kg/minute for orotracheal intubation. Variables recorded were (in minutes): time of extubation, time to return of palpebral reflex, eye recentralization, recovery of consciousness, quadrupedal position and total propofol dose used (mg/kg). A comparison between the 4 groups was performed by analysis of variance followed by Dunnett test under 5% significance. There was no significant difference in any of the times evaluated during anesthetic recovery between the groups. The propofol dose used to allow orotracheal intubation was significantly lower in all groups compared to TC (P < .05). Ketamine, midazolam, and fentanyl are indicated as suitable choices for coinduction with propofol in cats.

RESUMO

Cobalamin (vitamin B12) is important in gastrulation, nervous system development and haemoglobin formation. Mutations of the ABCD4 or LMBRD1 genes can lead to cobalamin-related disorders. We report a patient with disseminated skin hyperpigmentation caused by a homozygous LMBRD1 variant. Genetic disorders of cobalamin metabolism caused by variants in the ABCD4 or LMBRD1 genes should be considered in patients presenting with cutaneous hyperpigmentation.

RESUMO

This study aimed to investigate the effects of a single bolus and continuous rate infusion (CRI) of 1% propofol on cholesterol and triglyceride levels of healthy bitches undergoing elective ovariohysterectomy. 10 healthy bitches undergoing elective ovariohysterectomy had blood samples obtained at baseline (TB), 15 minutes following premedication with acepromazine and morphine (TPM), after an intravenous bolus of propofol (induction to anesthesia, TIND) and following 90 minutes of CRI of propofol started at 0.4 mg kg-1 min-1 and adjusted according to individual requirements (TCRI). Data were initially tested for normality using the Shapiro-Wilk test, and comparisons were performed using Friedman followed by Dunn post-hoc test. Serum cholesterol levels significantly decreased at TIND and TCRI (median [min-max] 201 mg dL-1 [111-234 mg dL-1], and 215 mg dL-1 [111-239 mg dL-1]), respectively, compared with TB (232 [128-245 mg dL-1]) and TPM (206 [115-255 mg dL-1]). No differences were found between TIND and TCRI. Triglyceride levels increased significantly at TIND (120 [67-231 mg dL-1]) and TCRI (229 [73-549 mg dL-1]) compared with TPM (36 [51-29 mg dL-1]), and TCRI compared with TB. In conclusion, 1% propofol lipid emulsion significantly increases serum triglycerides and causes lipemia in healthy dogs at a single bolus or CRI.

RESUMO

The persistent photoconductivity (PPC) effect is a commonly observed behavior in SnO2 nanostructures. Here we described and studied this effect through a comparative study, based on measurements of electronic transport using network as well as single devices built from SnO2 nanowires under different experimental conditions. At room temperature, the PPC effect was observed to be more accentuated in single nanowire devices. It was found that nanowire-nanowire junctions play a fundamental role in the device behavior: the decay time of nanowire network (τ = 52 s) is about three orders of magnitude lower than those of single nanowire (τ = 4.57 × 104 s). Additionally, it was confirmed that the PPC effect was directly related to the amount of oxygen present in the environment and it is destroyed with increasing temperature. Furthermore, the PPC effect was interpreted based on the surface effect that depends on the capture/emission of electrons by the surface states.

RESUMO

The present work was designed to compare four commercial samples of quercetin, three of them presenting pharmaceutical grade (QPGa, QPGb and QPGc) and the other one pro-analysi grade (QPA) by means of different techniques. Physical and chromatographic characterization of these samples shows different properties following its origin, especially a clear evidence of polymorphism occurrence.

RESUMO

OBJECTIVE: To describe the main cytological findings associated with smears collected from oral lesions of paracoccidioidomycosis and to appraise the use of cytology as a diagnostic tool for the disease. STUDY DESIGN: Cytological smears and biopsies were collected from 40 lesions with a clinical suspicion of paracoccidioidomycosis. Evaluation of the sensitivity, specificity, positive and negative predictive values, accuracy and the positive likeness ratio of the oral smear when compared with the histological diagnosis, was performed. The latter is considered the 'gold standard' for comparison. RESULTS: The main morphological findings were the rounded-shaped, birefringent and multiple-budded fungi, Langhans' giant cells and epithelioid cells. The following associative measures were found: sensitivity, 67.9%; specificity, 91.7%; positive predictive value, 95.0%; negative predictive value, 55.0%; accuracy, 75.0%; and positive likeness ratio, 8.14. CONCLUSION: The cytological findings of paracoccidioidomycosis are characteristic and cytology is accurate in the diagnosis of the disease. Positive patients should be treated. Negative patients should be submitted to biopsy to confirm or to dismiss the diagnosis of this mycosis.

RESUMO

A case of calcifying odontogenic cyst associated with compound odontoma in an unerupted primary tooth in a three-year-old patient is reported. Some considerations regarding the age of the patient, differential diagnosis and treatment are discussed. Although the cyst can occur at any age, the majority of cases appear before the fourth decade of life. This malady represents less than 2 percent of all odontogenic tumors and cysts.
