Abstract
We investigated the occurrence and pathologic findings of transmissible viral proventriculitis (TVP) associated with the chicken proventricular necrosis virus (CPNV) in commercial broiler chickens in southeastern Brazil. Seventy-three broilers, 25-36 d old, with a history of reduced growth, were referred to our veterinary pathology services from 2013 to 2017. Broilers were clinically examined, weighed, and euthanized for postmortem examination. Broilers of different ages with proventricular histologic lesions were positive for CPNV by RT-PCR; however, the intensity of histologic lesions was higher among 33-d-old animals, and viral RNA detection was more frequent among those that were 28 d old. In the proventriculi of 35 of 73 (48%) broilers, lesions were characterized by glandular epithelial necrosis, lymphoplasmacytic and histiocytic infiltrates, and metaplasia of glandular epithelium to ductal epithelium. In 24 of 73 (36%) broilers with histologic TVP-compatible lesions, CPNV was detected by RT-PCR for the viral protein 1 (VP1) gene. Broilers with histologic lesions were lighter than expected compared to the Cobb 500 standard weight. TVP has not been reported previously in broiler chickens in Brazil, to our knowledge.

Abstract
Chlamydia psittaci was detected in 152 (72%) blue-fronted Amazon parrots (Amazona aestiva, parrot from the Psittacidae family) out of a population of 212 that died during 2009-2011 in a wildlife rescue and rehabilitation centre in Minas Gerais, Brazil, following rescue from illegal wildlife trafficking. The macroscopic changes observed in these animals were hepatomegaly with multifocal white foci visible at the serosal surfaces of the liver, and extending into the parenchyma, and splenomegaly. The microscopic lesions observed in the liver included multifocal to coalescing miliary necrosis of hepatocytes with infiltration by heterophils, lymphocytes and plasma cells. In the spleen, loss of the normal architecture and infiltration by macrophages and plasma cells were observed. Stained tissue sections (Gimenez technique) revealed small round clusters suggestive of C. psittaci (reticulate bodies) in the cytoplasm of macrophages from the liver and spleen. Nine sequences of segments of the ompA gene, obtained from different individuals, were randomly selected for sequencing. The phylogenetic analyses showed that all strains clustered with genotype A, which is the most virulent genotype for birds. This genotype is involved in mortality of psittacines, is easily transmitted in captivity and represents a problem for successful rehabilitation. The results indicate the necessity to improve biosecurity in triage and to provide individual personal protection for professionals and caretakers.

Abstract
Foram utilizados 24 suínos machos castrados com o objetivo de determinar o efeito da temperatura ambiente sobre suas respostas termorreguladoras durante o estresse agudo por calor durante 48 horas. Os animais foram alojados em duas câmaras climatizadas com controle de temperatura, umidade e ventilação. Em uma das câmaras, os animais estavam em conforto térmico para a categoria (22ºC) e em outra, em estresse por calor (34ºC). Em cada câmara foram alojados 12 suínos, sendo a parcela experimental representada por dois animais na baia, totalizando seis repetições. As condições ambientais das câmaras climáticas e os parâmetros fisiológicos de frequência respiratória, temperatura retal e superficial foram monitoradas no início e a cada 12 horas durante o período experimental. No período observado, suínos em crescimento apresentaram respostas termorregulatórias efetivas a partir de 12 horas de exposição ao estresse agudo de calor (34°C).

Abstract
Extinct from nature, captive young Alagoas curassows (Pauxi mitu) were found agonizing or dead with respiratory disease. Intranuclear inclusion bodies were found in the epithelia of the trachea, associated with marked necrotic tracheitis. An Aviadenovirus was isolated in chicken eggs and characterized genetically with 99% identity to the fowl Aviadenovirus A, as based on the hexon protein gene. This is the first report of respiratory disease caused by Aviadenovirus in any cracid species in Brazil, recommending for stricter biosecurity in the conservation premises. RESEARCH HIGHLIGHTS Fatal tracheitis in curassows extinct from nature was associated with Aviadenovirus A. Seven-month-old Alagoas curassows (Aves: Cracidae) died with haemorrhagic tracheitis. Aviadenovirus A with 99% identity to fowl adenovirus 1 was detected in dead curassows. Fatal tracheitis by Aviadenovirus was described in Pauxi mitu (Aves: Cracidae).

Abstract
We present the case of a 29 year-old male with a tumor involving the mesencephalic tectum with associated hydrocephalus. Third ventriculocisternostomy was performed along with endoscopic biopsy; this provided adequate sampling of the tumor and enabled diagnosis of rosette-forming glioneural tumor (RGNT). The patient was followed for 48 months without progression of the disease. We review the features of the previous eight cases described in the literature and discuss the advantages of a minimally invasive approach and conservative management.

Abstract
ABSTRACT The first three jets of the sperm-rich fraction of Pêga jackasses were collected and assessed separately. Five fertile Pêga jackasses were used as semen donors and underwent fractionated semen collection, using an open model artificial vagina. The first three jets of the semen were collected separately and assessed for volume, sperm motility, vigor, concentration/mL of semen, and sperm morphology. These characteristics were compared between first, second and third jets and between jackasses. It was observed that the jet volume differed (P<0.05) between jackasses, although it was similar (P>0.05) between first, second and third jets. Sperm motility did not differ (P>0.05) between jets and jackasses. Vigor was similar (P>0.05) between jets of the same jackass, and only the first jet differed (P<0.05) between jackasses. The first, second and third jets of the sperm-rich fraction had decreased sperm concentrations (P<0.05) of 955.56, 725.56 and 280.56x 106 sperm/mL of semen, respectively. Sperm morphology differed between the first three jets only for the incidence of mid-piece defect, higher in the third one (4.26%), compared to the first (3.36%) and second (3.38%) ones. When comparing the morphological characteristics of the sperm-rich fraction between five jackasses, regardless of the jet, there were differences in the percentage of normal sperm, proximal cytoplasmic droplet, mid-piece and head defects.

Abstract
Thirty-six isolates of psittacid herpesvirus (PsHV), obtained from 12 different species of psittacids in Brazil, were genotypically characterized by restriction fragment length polymorphism (RFLP) analysis and PCR amplification. RFLP analysis with the PstI enzyme revealed four distinct restriction patterns (A1, X, W and Y), of which only A1 (corresponding to PsHV-1) had previously been described. To study PCR amplification patterns, six pairs of primers were used. Using this method, six variants were identified, of which, variants 10, 8, and 9 (in this order) were most prevalent, followed by variants 1, 4, and 5. It was not possible to correlate the PCR and RFLP patterns. Twenty-nine of the 36 isolates were shown to contain a 419 bp fragment of the UL16 gene, displaying high similarity to the PsHV-1 sequences available in GenBank. Comparison of the results with the literature data suggests that the 36 Brazilian isolates from this study belong to genotype 1 and serotype 1.

Abstract
AIM The aims of this study were to compare the volatile sulphur compounds (VSC)-reducing effect of two commercial mouthrinses using a morning bad breath model and to assess the role of mechanical plaque control (MPC) when performed previously to mouthrinse use. PATIENTS AND METHODS Eleven volunteers with good oral health were enrolled in a double-blind, randomized, six-step crossover design study with a 7-day washout period. Two commercial mouthrinses were tested using a saline solution (NaCl 0.9%) as a negative control: one mouthrinse contained 0.05% chlorhexidine, 0.05% cetylpyridinium chloride and 0.14% zinc lactate (CHX-CPC-Zn), while the other contained 0.05% chlorhexidine, 0.15% triclosan and 0.18% zinc pidolate (CHX-triclosan-Zn). A portable sulphide monitor (Halimeter(®) ) was used for VSC quantification. Measurements were made at baseline, and 1, 3 and 5 h after rinsing. Significant differences were detected by analysis of variance. RESULTS No significant differences between groups were detected at baseline. We were unable to demonstrate a significant influence of mechanical plaque control on the reduction of VSC levels when performed before mouthrinse use (P = 0.631). Both mouthrinses effectively lowered VSC levels in all test intervals (P < 0.05). No statistically significant differences were found between mouthrinses in any of the test intervals (P = 0.629, 0.069 and 0.598 at 1, 3 and 5 h). CONCLUSION This study demonstrated that CHX-CPC-Zn and CHX-triclosan-Zn have significant and similar effects in reducing VSC levels, which persist for at least 5 h. Such effects were independent of previous MPC, which failed to improve on the results of mouthrinse use alone.

Abstract
The occurrence of Aviadenovirus (FAdV) was investigated in chickens from the poultry industry of Minas Gerais state, Brazil. The investigation was conducted due to the scarcity of recent data in the country and its description in neighboring countries. For this purpose, livers were collected from layer chicks (n=25), older layers (n=25), broilers (n=300), and livers (n=25) and stool (n=25) samples from broiler breeders, representing the major poultry regions of the state. FAdV DNA was demonstrated using a previously described PCR protocol for amplifying part of the hexon gene encoding sequence. FAdV was found in layer chicks (36%), widespread (100%) in older layers, and with regional differences in broilers (24-86%). Although all broiler breeder stools were negative, FAdV DNA was detected in livers (16%, 4/25) of stool-negative birds. In order to obtain additional information on the circulation of the infection, livers of subsistence chickens collected from one poultry intensive region, were evaluated (n = 12), with FAdV being detected in all samples. FAdV was found in young and old layers, broilers, broiler breeders and free-range chickens, and results suggest the circulation of FAdV among different types of chickens. The detection in older layer chickens may indicate an extended risk of horizontal transmission in regions of Minas Gerais with mixed activity of egg and meat type chickens and poor biosecurity strategies. The infection in breeders may indicate vertical transmission and the continuous production of infected progenies. The hexon-gene-targeted PCR amplicon sequences aligned with FAdV of species D of Aviadenovirus. Results indicate the necessity for biosecurity, especially for breeders, separating flocks according to origin, age and health status, which will be an advantage regarding any pathogen.

Abstract
Fifty-four fecal samples taken from broiler chickens from 1 to 45 days of age, and of pullets from 10 to 13 weeks of age, original from eight different poultry regions in the state of Minas Gerais, Brazil, were collected from March 2008 to January 2010 for avian Orthoreovirus (ARV) and avian Rotavirus (AvRV) analyses. For the assay of ARV, RNA was immediately extracted (Trizolâ) and transcribed into cDNA for assaying in a nested-PCR with ARV-specific primers. For AvRV, polyacrylamide gel electrophoresis (PAGE) was performed with RNA extracts obtained by phenol-chloroform extraction. CAV was additionally investigated through a nested-PCR of thymus and spleen. Results found 5.55% positive for ARV and 9.25% for AvRV. Also, CAV and ARV genomes were detected in co-infection, in a highly prostrated and claudicating chicken flock. No ARV or AvRV infections were detected in pullets. Material of a clinically affected flock was inoculated into SPF embryos, resulting in embryonic hemorrhage, whitish foci in the chorio-allantoic membrane and death. Sequencing of ARV amplicons and isolate cDNA grouped local strains with the ARV S1133 strain, historically used in live vaccines, suggesting the continued circulation of this vaccine virus strain in intensive poultry regions. Detection rates for ARV and AvRV, as well as the presence of CAV, were additionally indicative of failing biosecurity strategies for the intensive poultry regions examined.

Abstract
Psittacid herpesvirus (PsHV) was isolated from 41 birds kept in captivity in Belo Horizonte, Minas Gerais/Brazil using chicken embryo fibroblasts (CEF) cell cultures. For this study, leukocytes or cloacal swabs of live birds were used. Also, portions of liver, spleen or kidney from birds collected at necropsy were utilized for these tests. PCR tests confirmed the presence of PsHV in 100% of samples. Thirty-three of the PCR products were sequenced and the results disclosed a 99% and 100% identity when compared with other sequences PsHV-1 (AY372243.1 and AF261756.1), previously deposited in GenBank. In addition, histopathology was performed and 19 of the 29 birds contained random multifocal lymphoplasmacytic hepatitis with necrotic foci, suggestive of viral infection. Three samples were examined by electron microscopy to visualize the viral particles obtained from cell culture. The viral structures measured 269 nm in average, had envelopes with an icosahedral capsid and tegument, consistent with herpesvirus. Thus, a total of 41 isolates were obtained from PsHV cell cultivation in CEF, confirming the circulation of the virus between parrots kept in captivity in Belo Horizonte, and affirming the importance of further studies in this area.

Abstract
A vaccine protecting women against placental malaria could be based on the sub-domains of the VAR2CSA antigen, since antibodies against the DBL4ɛ-ID4 subunit of the VAR2CSA protein can inhibit parasite binding to the placental ligand chondroitin sulphate A (CSA). Here we tested the ability of DBL4ɛ-ID4 to induce binding-inhibitory antibodies when formulated with adjuvants approved for human use. We have characterized the immune response of DBL4ɛ-ID4 in combination with Freund's complete and incomplete adjuvant and with three adjuvants currently being used in clinical trials: Montanide(®) ISA 720, Alhydrogel(®) and CAF01. Antibodies induced against DBL4ɛ-ID4 in combination with these adjuvants inhibited parasite binding to CSA from 82% to 99%. Although, different epitope recognition patterns were obtained for the different formulations, all adjuvant combinations induced strong Th1 and Th2 type responses, resulting in IgG with similar binding strength, with to the DBL4ɛ-ID4 antigen. These results demonstrate that the DBL4ɛ-ID4 antigen is highly immunogenic and that binding inhibitory antibodies are induced when formulated with any of the tested adjuvants.

Abstract
A nested PCR assay was used to diagnose bovine encephalitis through herpesviruses including bovine herpesvirus 5 (BHV-5), bovine herpesvirus 1 (BHV-1), Aujeszky's disease virus (SHV-1), and ovine herpesvirus 2 (OHV-2) in 14 fragments of central nervous system (CNS) from cattle that died with neurological signs. In addition, as some samples of bovine herpesvirus type 4 (BHV-4) have been isolated from neural tissue, it was also tested by nested PCR. The cases of encephalitis occurred in isolation at different times of the year and did not present any seasonality. The duration of the clinical course ranged between 1 to 15 days, and in 64.3% of the cases it manifested between 1 to 2 days. The most frequently observed neurological signs were ataxia, recumbency, unsteadiness and inability to stand, opisthotonus, paddling movements, nystagmus and ptyalism. In the nested assay, there was no evidence of: BHV-1, SHV-1 or OHV-2 in the DNA obtained from the CNS in any of the samples. But the presence of BHV-4 was found in all fragments of the CNS in cattle which died presenting neurological signs. Moreover, BHV-5 was found in association with BHV-4 in two of these samples.

Abstract
BACKGROUND Corrective eyeglasses are frequently worn by adults, particularly at older ages. Their lenses and frames provide ultraviolet protection. Medial canthal basal cell carcinomas are infrequent (3-8%), and their relation with the use of corrective glasses was not yet investigated. OBJECTIVES To assess the prevalence of corrective eyeglasses use in individuals with medial canthal basal cell carcinoma. METHODS Case-control study using two controls matched by age, gender, and ethnicity for each case. Cases were patients with medial canthal basal cell carcinoma, and controls were patients with basal cell carcinoma elsewhere on the face. The prevalence of major risk variables was estimated and adjusted by conditional multiple logistic regression. RESULTS Fifty cases and 100 controls were assessed. The mean patient age was 69.7 years, and 54% of the subjects were females. No difference regarding the eyeglasses use or use duration was found between groups. However, when visual defects were separately evaluated, eyeglasses for myopia correction were independently associated with lower risk of medial canthal basal cell carcinoma development (OR=0.26; P=0.03), what can be related to long term local photoprotection. CONCLUSION The use of eyeglasses for myopia correction is associated with lower prevalence of medial cantal basal cell carcinoma. Risk-reducing mechanisms should be elucidated.

Abstract
Durante o período de Outubro de 2004 a Fevereiro de 2006, 75 amostras de sistema nervoso central (SNC) oriundas de eqüinos que morreram com sinais neurológicos no estado de Minas Gerais foram enviadas ao Laboratório de Virologia Comparada no ICB/UFMG para o diagnóstico de herpesvírus eqüino. Essas amostras foram previamente diagnosticadas negativas para o vírus da raiva através dos testes de imunofluorescência direta e inoculação em camundongos, no Laboratório de Saúde Animal (LSA) do Instituto Mineiro de Agropecuária (IMA). Dentre as amostras analisadas, 39 (52%) foram positivas para o herpesvírus eqüino 1 (EHV-1) através da técnica de reação em cadeia pela polimerase (PCR). Na maioria dos casos, o exame histopatológico do SNC revelou uma discreta vasculite com infiltrado perivascular de células mononucleares, congestão, trombose arterial e degeneração do tecido nervoso central. As amostras de SNC positivas para o EHV-1 foram coletadas de eqüinos oriundos de 30 municípios de Minas Gerais. Os casos de EHV-1 ocorreram de forma isolada não apresentando caráter sazonal. Na maioria dos casos (71,8%), a evolução dos sinais clínicos foi aguda, sendo que os sinais clínicos observados com mais freqüência foram ataxia, instabilidade dos membros posteriores, paralisia dos membros posteriores e decúbito. De acordo com informações relatadas pelo IMA, as infecções causadas pelo EHV-1 foram tão freqüentes como as infecções causadas pelo vírus da raiva em eqüinos no estado de Minas Gerais durante o período estudado. Portanto, torna-se importante a inclusão da encefalite pelo EHV-1 no diagnóstico diferencial de outras doenças do SNC de eqüinos no estado de Minas Gerais.

Abstract
An outbreak of Malignant Catarrhal Fever (MCF) resulted in death of five female buffaloes and one domestic cow from the same farm. Four buffaloes died 10-15 days after the appearance of clinical signs, while the fifth was euthanized in extremis, after similar clinical signs. Histopathological lesions included multifocal histiolymphocytic epicarditis, myocarditis and lymphocytic interstitial pneumonia, which are commonly seen in cases of MCF in buffaloes. Furthermore, lymphocytic vasculitis centered in the adventitia, with occasional fibrinoid necrosis in the muscular layer, was found in the kidneys, liver, spleen, lymph nodes and brain. Nucleotide sequencing of DNA fragments from the central nervous system amplified by PCR revealed 98% similarity with known OHV-2 sequences from Genbank. Additionally, PCR analysis also revealed the presence of OHV-2 DNA in the peripheral mononuclear blood cells of two clinically healthy buffaloes. The diagnosis of MCFwas based on epidemiological, clinical, gross and histopathological findings and on the results of a semi-nested PCR followed by nucleotide sequencing.

Abstract
INTRODUCTION Vascular malformations are uncommon causes of aqueductal obstruction. To our concern, only one case of hydrocephalus caused by a venous varix draining an unruptured arteriovenous malformation has been described in the literature. CASE REPORT We report the case of a 70-year-old woman presenting with progressive cognitive impairment, gait disturbance and urinary incontinence. Magnetic resonance imaging and magnetic resonance angiography revealed a large venous varix draining an unruptured arteriovenous malformation causing hydrocephalus. CONCLUSION Although uncommon, it is necessary to consider the presence of a vascular malformation in adults who presented with signs of aqueductal obstruction.

Abstract
A nested-PCR (n-PCR) was used to detect feline leukemia virus (FeLV) proviral DNA in blood samples from 464 sick and 608 healthy domestic cats (Felis catus) selected by convenience, and a significantly high prevalence of FeLV infection was observed. n-PCR results revealed the presence of FeLV proviral DNA in 47.2 % of sick cats and 47.4 % of healthy cats. Phylogenetic analysis revealed that FeLV samples from healthy or sick cats were grouped into separate clades. We determined FeLV subgroups by an n-PCR based on the envelope (env) gene. The partial env gene of FeLV Minas Gerais (MG) samples were compared to various exogenous FeLV isolates and endogenous (enFeLV) provirus from the same region. FeLV-B MG samples were more similar to endogenous sequences and to natural FeLV-B isolates than to either FeLV-A or FeLV-C. The results revealed the circulation of FeLV-B in large populations of urban domestic cats in Brazil.

Abstract
An intra-conical histologically malignant solitary fibrous tumor of the orbit presented in a 28 year-old female with intact vision and exophthalmos. Total resection was achieved by means of a frontal craniotomy and orbital roof osteotomy. Evidence of a beneficial role for adjuvant treatments in this particular tumor is controversial and vision impairment is a possible side effect. Therefore they were not employed. The patient is well after two years of follow-up.

Abstract
11528 Background: The authors analyse retrospectively the impact on tumour control and toxicity of concomitant radiotherapy (RT) and Temozolomide (TMZ) in high grade gliomas (HGG) of the CNS, in patients treated in the Clínica de Radioterapia do Porto - Portugal. Methods: This cohort represents all patients with HGG treated between January 2002 and January 2006, with concomitant RT a median total dose of 60 Gy, 2 Gy per treatment given once daily 5-days/week and TMZ 75mg/m2 for 42 days, followed by adjuvant treatment with TMZ 5-days schedule every 28 days (150 mg/m2 for the first cycle increased to 200mg/m2). The cohort was retrospectively analyzed for gender distribution, age, extent of surgical resection, initial KPS, median overall survival (OS) and haematological toxicity. Results: 23 with HGG (6 females, 17 males) were treated with concomitant RT (44–72 Gy) and TMZ followed by adjuvant TMZ; median age was 58 (ranging from 17–72); median KPS was 80 (ranging from 40–90); 3 patients had complete resection, 17 partial resection and 3 biopsy. All patients except one, who had treatment interruption for thrombocytopenia, completed the concomitant phase of treatment; 19 patients continued to received adjuvant treatment with TMZ (median number of cycles was 5 (ranging from 1–20). Median OS (measured from the date of diagnosis to the date of death) was 20.4 month and 1 yr OS was 54%. During concomitant phase, one patient had grade 3–4 thrombocytopenia. During the adjuvant TMZ therapy 4 patients had grade 3–4 haematological toxicity (anaemia: 1; thrombocytopenia: 1; leucopoenia and thrombocytopenia: 2). Conclusions: The results of concomitant RT+TMZ followed by TMZ in these patients with HGG showed values in accordance with the latest data published on literature for this association. Differences observed might be due to the small sample size.RT+TMZ followed by adjuvant TMZ is a well tolerated treatment with better results in median OS comparatively with previous results of RT only treatment in HGG. Treatment related toxicity was within acceptable levels, and this approach became routine practice in this set of patients. No significant financial relationships to disclose.

Abstract
SUMMARY. This study aimed to genotype infectious bursal disease virus (IBDV) isolates from the Minas Gerais state poultry industry. RNA was extracted from bursae obtained from field cases without passage or commercial vaccines. Genetic subtyping of IBDV isolates and vaccine strains was carried out by the reverse transcriptase-polymerase chain reaction (RT-PCR) and restriction fragment length polymorphism (RFLP) analysis. A 588-bp fragment in the VP1 gene, an 847-bp fragment in the VP2 gene, and a 320-bp fragment in the VP3 gene were amplified by PCR and digested with restriction enzymes PstI and ScaI (VP1); BamHI, BstEII, and PstI (VP2); and NcoI, ScaI, and XbaI (VP3). Our work shows that complementing the clinical history of the outbreaks with RT-PCR followed by RFLP analysis using PstI for VP1, BamHI for VP2, and XbaI for VP3 allowed an accurate classification of a causative agent as a very virulent IBDV.

Abstract
A cavernous malformation involving the Gasserian ganglion, 2nd and 3rd divisions of the trigeminal nerve on the left side was resected via an extradural route in a 54 year old male. Cavernous malformations of the cranial nerves are rare. Specific origin from the trigeminal nerve has not been previously reported.

Abstract
Seventy-two patients submitted to meningioma surgery at Pedro Hispano Hospital from 1997 to 2001 were reviewed to analyze the association between size (largest diameter of the lesion obtained from imaging examinations) and other variables regarding the biological behavior and clinical outcome of these patients. Statistically significant associations were found between tumor size and location, type of first symptom, type of physical examination, histological grade, surgical complications, postoperative CSF bursae and the need for blood transfusion. Patient's age, gender, duration of first symptom, clinical status at discharge and persistent complaints were not associated to tumor size. There was a trend towards a statistically significant association between tumor size and both grade of resection and persistent deficits. The causes and implications of the findings are discussed. Tumor size is a parameter that may interfere with the neurosurgeon's capacity to treat these patients as well as with their recovery.

Abstract
A case of conventional intramedullary osteosarcoma (epithelioid subtype) with 10 years of evolution and another of high grade surface osteosarcoma of the chondroblastic type, both in the skull, gave rise to several diagnostic and therapeutic difficulties. Key points concerning the definition, classification, imaging, clinical series data and treatment options available for skull osteosarcoma are highlighted.
